Friends, we are really tired of eating melons.Zhang Xiaohan, who is not very reliable, has drawn cartoons again!

This time, she still rushed to the hot search with ambiguous melons. According to her description, a "first-line intellectual actress" who is famous for her urban drama met with a married rich man in a hotel in Hainan, and the rich man also sent the actress high-luxury jewelry worth tens of millions to make her happy …

Regardless of whether this melon is real or not, who will take care of Zhang Xiaohan! Put it directly with a hammer. Stop drawing cartoons! Few of the comic books she drew before have ever come true …

But this netizen is right. People’s curiosity can’t be suppressed. Although we scold Zhang Xiaohan for having no credibility, we still can’t help but look for an "intellectual actress" who can sit in the right place according to the information disclosed.

Some netizens have even started to list the names of qualified actresses, such as Jiang Shuying, Dilraba, Angel, Chen Shu, Song Jia Jr., Sunny, Chen Douling, Wu Jinyan … The appraisal criteria are based on the paparazzi’s phrase "an intellectual actress who is famous for her urban drama".

Among them, Jiang Shuying was listed as the most likely actress by netizens because of too many details.

First of all, Jiang Shuying was really helped by the fire in Nothing But Thirty, and she did play a lot of urban dramas herself. It can be said that when I saw her face, I couldn’t help but think of urban female roles such as Jiang Lai and Wang Manni.

Recently, in Ode to Joy 3, Jiang Shuying still plays an urban white-collar Ye Zhenzhen.

Secondly, Jiang Shuying really went to Hainan recently and had a beautiful photo. In the photo, she has long hair, and the red flower in her ear seems to echo the red flower on the plate in Zhang Xiaohan’s cartoon.

As it happens, Jiang Shuying has also sent several selfies recently, and the jewels in the selfie are particularly eye-catching. Immediately, some netizens said: "Is this the jewelry sent by a wealthy businessman, so it is the show of love?"

However, some netizens immediately clarified that they searched for the same model in Jiang Shuying’s selfie. The bracelets and watches are more expensive, but as an actress in Jiang Shuying’s coffee spot, she can afford them. The necklace is only a niche brand with more than 1,000 pieces, which can’t reach the level of "ten million yuan jewelry" at all.

Jiang Shuying and his studio also denied this speechless rumor., the tone is full of helplessness:"I can be talked about, but I can’t be framed."

Then netizens found out that,The characters of wealthy businessmen and wives in cartoons seem to be very similar to those of Yu Dong, president of Bona Film, and his wife Jin Qiaoqiao., just Jin Qiaoqiao also dyed red hair.

After reading the so-called "evidence" dug up by these netizens, my little sister is completely speechless, and everyone’s ability to learn from the melon is really getting better and better!

Then Jin Qiaoqiao sent a message to respond to this matter:"Rumors stop at the wise! Watch more movies when you have time. "

Later, Jin Qiaoqiao replied to the comments of netizens in the comment area. In the face of the "persuasion" of netizens, my sister said that she was too speechless:"Can you don’t believe those false news that are fabricated and maliciously slandered on the Internet! It’s all fake! Fake! Fake! " "This netizen? Can you have a little brain? "

There are even netizens who call Jin Qiaoqiao the "little three" of Yu Dong, and Jin Qiaoqiao is so angry that he directly returns.: "Who are you talking about? Spread rumors? ! If you don’t get it, you have to take a lawsuit! "

Here, my little sister wants to get a word in,Jin Qiaoqiao clarified the "mistress" as early as 2014.Yu Dong ended his first marriage in 2010, and he and Jin Qiaoqiao only met in 2012, so there is no such thing as "mistress intervening".

Then Jin Qiaoqiao called Zhang Xiaohan, saying that he was also curious about who the three people in his cartoon were, and had to say that Jin Qiaoqiao was somewhat domineering!

Speaking of Jin Qiaoqiao, I believe that everyone’s first impression of her is stillThe charming and charming peacock princess in the 98 edition of The Journey to the WestOk! It is this role that opened her up.The road of "princess professional household".

The second princess in the East China Sea in "Pig Eight Rings in Spring" is also unforgettable, and Jin Qiaoqiao’s delicate, expensive and sweet appearance is really very suitable for playing the princess.

Princess Yuzhen in "The Secret History of Yang Guifei" is even more compassionate. Some netizens even commented that she is very "Guanyin" and has a kind face and a beautiful face.

Because of her extraordinary and recognizable beauty, Jin Qiaoqiao has been quite successful in her career since she graduated from Nortel, which is enough for most students to envy.

It is said that you can’t have both career and peach blossom, but Jin Qiaoqiao is different, and her peach blossom has never been bad.

No, Jin Qiaoqiao’s first love was vigorous enough. He directly held hands with Wu Qihua, the top student of TVB at that time, and officially announced his love affair. If this were put in today, it would be enough to paralyze the server.

At that time, Jin Qiaoqiao was quite pure and beautiful, and her figure was full of pure desire. She was a little girl with a happy face. Look at this dress, it is not out of date now!

Although Jin Qiaoqiao’s mother thinks that Wu Qihua and Jin Qiaoqiao are too different in age and somewhat introverted, she thinks that her daughter will not be happy to live with him.

But when the two were in the thick of love, they couldn’t listen to their parents’ thoughts at all.Wu Qihua even bought a mansion in Shanghai and gave it to Jin Qiaoqiao in the name of "wedding room"It is said that it cost 1.6 million, which was 1.6 million in 2003.

The good times didn’t last long, and the two finally broke up.After all, Wu Qihua is a "playboy" with too much romantic history, and it is really difficult to get results in falling in love with him.

Later, Jin Qiaoqiao has been caught in various scandals, but there has been no "positive fate".

For example, Jin Qiaoqiao, the unspoken rule of Zhang Guoli, was also caught by Deng Jie (although it seems that there is no real hammer at all now, it is just an empty talk and a visual sense) ↓

Some netizens broke the news that they had picked up Jin Qiaoqiao’s mobile phone, saying that Jin Qiaoqiao had received an ambiguous text message from a wealthy businessman who wanted to pay for her dinner date. The text message boasted:"We are not short of money, what price, Miss Jin can say. Whatever you want, we will never make a counter-offer. "

It’s not a scandal, can only say that the entertainment circle at that time was really in hot water …

Jin Qiaoqiao’s second love affair was with Yu Dong, CEO of Bona Film, and they went straight to the marriage hall. Jin Qiaoqiao also gave birth to a son and a daughter for Yu Dong.

I mean, I’m really principled, and I don’t talk much about love, either talking about being popular or talking about movie mogul.

After marrying the president, Jin Qiaoqiao is almost in a state of retirement. She has been working as a full-time mother at home, and her personal social accounts also record anecdotes about her children’s growth, and only occasionally does Yu Dong appear.

Netizens are deeply touched by this.In the past, the goddess became a child nanny after marrying into a rich family, or was she a "widowed baby"!

E-mail flipped through Jin Qiaoqiao’s account and found that there were not many children’s fathers.

Either take your children out with your parents ↓

Or take two dolls to the playground by yourself.

Recently, however, some netizens ran into Jin Qiaoqiao and Yu Dong to take the children to Universal Studios. My son took his mother’s hand and Yu Dong touched his son’s head while listening to the voice. The picture was quite warm. It seems that they were very happy, and netizens were also worried about it.

Although Jin Qiaoqiao has been a stay-at-home housewife for many years, it seems that her life is empty and her career is barren, but at least she is also a serious "Bona boss".

It’s up to her to hold a birthday party, and almost half of the big coffee in the entertainment circle came to celebrate her birthday., Jason Wu, Iola, Jet Li, Tung shing Yee, Xiang Huaqiang, Xiangtai, Zhang Ziyi, Li Xiang, Chiu Man-Cheuk, Pu Cunxin, Fan Ming, Fu Disheng, Ren Jing, Chen Xiao, Huang Yi, Tan Jing, Chen Xuedong … How many female stars can do this in-plane entertainment?

Jin Qiaoqiao had nothing to do but open a hot pot restaurant to kill time. Stars such as Yao Chen, Jerry Lee and Lin Yongjian rushed to call her new store, and her contacts were quite amazing.

Perhaps the family can also be a woman’s career. Although Jin Qiaoqiao has been away from the entertainment circle for many years, who said that it is not a real skill to run the family well? (text/seedling bag)

Mesenchymal Stem Cell (MSC) have unique biological characteristics and therapeutic potential, and are becoming a "new star" in the field of disease research, and the research enthusiasm continues unabated. MSC involves many related researches, such as multiple sclerosis, arthritis, neuropathic pain, intestinal diseases, etc., and is a research hotspot in the field of transplantation and autoimmune diseases.

Statistics on the number of published papers in MSC field from 2014 to 2024, with data from Pubmed.

Mesenchymal stem cells (MSC) are pluripotent stem cells derived from mesoderm with high self-renewal and multi-lineage differentiation potential. They are widely distributed in various tissues of the whole body, with the advantages of easy separation and easy acquisition, and can be differentiated and expanded in vitro.

MSC is an excellent tool for tumor therapy and gene transfer research, functional genomics, drug screening, Qualcomm screening and toxicology. International Association for Cell Therapy (ISCT) defines human MSC as:

Under standard culture conditions, it is adherent growth;

CD105, CD73 and CD90 should be expressed, but CD45, CD34, CD14 or CD11b, CD79α or CD19 and HLA-DR surface markers should not be expressed.

It can differentiate into osteoblasts, chondrocytes and adipocytes in vitro.

Mesenchymal stem cells come from a variety of cells or tissues, such as bone marrow, adipose tissue, peripheral blood, placental tissue, dental pulp and so on. Similarly, MSC can also differentiate into many cell types, such as osteoblasts, chondrocytes, fat cells, muscle cells, nerve cells, stromal cells and so on.

The origin and differentiation of MSC (from references)

It is worth noting that the differentiation potential of mesenchymal stem cells may vary with the source of stem cells, expansion conditions and their culture microenvironment. Three-line differentiation is the focus of MSC culture and amplification. Triple differentiation usually refers to osteogenesis, adipogenesis and chondrogenesis. In order to better understand the triple differentiation of MSC, this paper preliminarily summarizes the general process of triple differentiation of MSC and the identification methods corresponding to some markers.

Osteogenic differentiation

MSC can directionally differentiate into osteoblasts under the stimulation of various cytokines and other physical and chemical environments. Then the osteoblasts further differentiated into osteoblast precursor cells and entered a rapid proliferation period. Osteoblasts synthesize and secrete organic matrix at this stage, forming osteoid (mainly type I collagen), characterized by alkaline phosphatase, which is an early sign of osteoblast differentiation and maturity; Alkaline phosphatase appears blue under the microscope after fixation with blue, while undifferentiated cells have no obvious color.

Mature osteoblasts express ECM calcification-related proteins. Long-term osteogenic induction causes calcium ions to precipitate in the form of calcium salts, forming "bone nodules". Bone nodules can be dyed deep red by alizarin red (alizarin red reacts with calcium to produce a deep red compound), and the strength of osteogenic differentiation can be expressed by the area and depth of the pigment.

Identification of osteogenic differentiation of MSC from different sources

Chondrogenic differentiation

Firstly, MSC gathers into a cluster, and the middle cells in the cluster are transformed into a large and round cell, that is, chondrocyte, through division and differentiation. Chondrocytes produce matrix and fibers (mainly type II collagen), and the expression of type II collagen was observed by immunohistochemistry.

Generally, the differentiation results of chondrocytes were identified by Alyssin Blue. Alisine blue is an alkaline dye, which can combine with nucleic acid in cells to make the nucleus dark blue. At the same time, alisin blue combined with polysaccharides in cartilage matrix, making cartilage cells and matrix light blue.

Identification of chondrogenic differentiation of MSC from different sources

Adipogenic differentiation

There are two stages of adipogenic differentiation of MSC: first, it differentiates into adipose precursor cells, and then it differentiates into adipocytes under the influence of specific stimuli (such as C/EBPs and PPAR-γ).

Cells keep accumulating fat droplets in the cytoplasm and getting bigger. After dyeing with oil red O, it is red under the microscope. Undifferentiated cells have no obvious color.

Identification of chondrogenic differentiation of MSC from different sources

Various factors will affect the differentiation potential. Such as culture environment, growth factors and the existence of other cells, will affect the differentiation process. Specific signal molecules, such as bone morphogenetic protein (BMP) or Wingless related integration site (Wnt), can promote the differentiation of stem cells into bone cells or nerve cells, respectively.

The research on mesenchymal stem cells is so hot that Yiqiao Shenzhou has compiled a detailed MSC operation guide. Protocol is full of dry goods, in addition to the above three-line differentiation identification examples, it also includes how to isolate mesenchymal stem cells, how to subculture and expand them, and how to determine that the expanded cells are mesenchymal stem cells.

I haven’t seen CoCo Lee for a long time. Last night, a Weibo made everyone guess.

I wonder what happened to her.

Last night, some people suspected that she was in a bad state and suspected of depression, and some said that she was in a marital situation.

Sister CoCo Lee responded that if it is about CoCo Lee’s marriage, it is best for her sister to explain it herself, but please don’t be too sensitive.

CoCo Lee’s husband is Canadian tycoon Bruce, whose Chinese name is Le Yumin. He used to be the partner of Li Zekai Colby NetLtd, and he has been the executive director of Libiao since 2001 and the president of Libiao (Trade) since 2004.

The difference between them is 17 years old. In 2011, they got married after 8 years of love running.

At that time, the wedding was quite luxurious, and it was said that it cost as much as 120 million yuan. Many big coffees at home and abroad attended the gathering of stars, and the performing guests included Alicia keys, Brother Mars, black eyed peas and so on.

CoCo Lee’s marriage life has always been low-key, and the luxury wedding was also kept secret all the time, but it was unexpected to pass on the marriage change.

Private life is not easy for outsiders to evaluate, but I still hope that coco will be all right.

Tom Hiddleston, a "Shake-off" actress, has been exposed to live with Zawe Ashton, who is three years younger.

The two men were exposed to love in September last year, but Shakeson’s friends denied that they were dating.

Now foreign media once again broke the news that the woman had moved to Atlanta to live with Dawson. People familiar with the matter said: "Tom and Zawei have been silent about their relationship, but in recent weeks, she has been accompanying him in the United States. They are very suitable, enjoying the quieter side of life and staying away from the glitz and charm of the entertainment industry. "

I saw that many netizens questioned the woman’s appearance, but the girls are stage performers and quite talented. They are good at writing poems, publishing books and acting.

When people get along together, they may not care about their faces at all.

> come on, friend, dog food is coming again.

>Lu Han and Guan Xiaotong again.Show a low-key love, give it.Everyone sent a wave of dog food that was secretly poked.

>In the promotional video recorded by Guan Xiaotong for the new drama, netizens found that the curtains in the video were the same as those in the previous video recorded by Lu Han.

It’s really easy for lovers in love to reveal small details.

Since the announcement of their love affair, the number of public shows of love is not much, but there are always the same clothes and shoes, and the sweet little details in life can’t be hidden.

Remember that rich third-generation boyfriend Shi Boxiong who has been circulating since Wu Qianyu and raymond lam broke up?

The eldest grandson of Hong Kong real estate developer Shi Ziqing, the family has tens of billions of assets.

Before Wu Qianyu and raymond lam officially admitted to breaking up, it was always said that it was because the woman had hooked up with the rich three generations.

Shi Boxiong attended the dinner and often played together in private.

However, compared with raymond lam and Zhang Xinyue, their subsequent relationship has been unclear.

Wu Qianyu has publicly dried the flowers that Shi Boxiong gave her. Many netizens ridiculed that she was deliberately exposed and secretly poked to put pressure on Shi Boxiong?

Later, when asked about her boyfriend by the Hong Kong media, she said that she was not ready and wanted to slow down.

Last year, I also sent an ins, which suspected that I was single.

However, in March this year, the two were photographed going out for an outing together, which can be regarded as a rumor that their love affair died.

There is also a Hong Kong media exposure that the two have moved into a new mansion to live together, and the Qianyu BB with a stable relationship is also likely to marry a rich family and make a positive result.

Undoubtedly, the ideal is the best among the new power brands at present, and the world of inquiry has become the biggest competitor of the ideal by the bright performance of M7 and M9, and with the exposure of the brand-new world of inquiry M8, the impact of the world of inquiry on the sales volume of the ideal market continues.

Although the new car may not be officially released until Guangzhou Auto Show, the popularity of M8 in the world is very high, and the empowerment of Huawei’s black technology has become the focus of attention in the automotive industry. Moreover, according to the current product camp, it is not difficult to speculate that the pricing of new cars may be in the range of 350,000 to 450,000 yuan, directly targeting the popular and other models in the current market.

Therefore, this model not only bears the heavy responsibility of breaking through the brand in the world, but also has high hopes to become the key to surpassing the ideal of competitors in sales. It is reported that the M8 will be listed at the end of February, and the new car will be delivered in early March. This compact listing rhythm undoubtedly shows the confidence and expectation of the M8 market performance.

According to the exposed pictures, Wen Jie M8 shows a completely different style from and M9 in appearance design. The front face of the new car adopts a brand-new headlight group. Although it retains the family-style design language of the through belt, the details are more exquisite and unique. The design of the closed grille at the front of the car and the possible adjustment of the lamp style indicate that the M8 will bring a refreshing visual experience while maintaining its family characteristics.

As for the interior, the M8 has been innovated and optimized on the basis of inheriting the design of the M9 triple screen, and the right angles on both sides have become rounded corners, which are matched with diamond decorative plates, star ring scatterers, projection giant screens and other elements to create a more luxurious and technological driving atmosphere.

What’s more, the M8 will be equipped with the Rubik’s Cube platform for the first time. This innovative platform not only endows the new car with the unique skill of rear wheel steering, but also indicates the infinite possibilities of the brand in the future product layout.

The Rubik’s Cube platform will be compatible with cars, SUVs, MPVs, pure electric vehicles, extended range, hybrid vehicles and other power forms, laying a solid foundation for the sustainable development of the brand. In the future, with the advent of more models based on the Rubik’s Cube platform, the product matrix of Wenjie brand will be more perfect and the market competitiveness will be significantly improved.

In terms of battery life and charging, the M8 also showed strong competitiveness. The new car will be equipped with the "Whale" 800V high-voltage battery pack. By greatly reducing the number of wire harnesses and the thickness of the battery pack, the fast charging ability of 150 kilometers in 5 minutes is realized.

At the same time, the pure battery life of the M8 is expected to exceed 600 kilometers, and the extended-range version will exceed 1,400 kilometers, which can easily cope with both urban commuting and long-distance travel, showing excellent battery life and fuel economy performance. If this is the case, the M8 can not only balance the problems of endurance anxiety and high oil price pressure, but also attract users’ attention with the blessing of various black technologies.

Write at the end:

At present, with its precise market positioning, innovative design, luxurious interior configuration and strong technical strength of Sanpower, Wenjie M8 can become a group of dark horses in the next new energy vehicle market. In the future market competition, ask whether M8 can successfully surpass competitors such as Ideal with these advantages, realize the leap-forward growth of sales volume, and once again "cripple" the ideal. Everyone who eats melons can look forward to it.

On the First Session of the 11th Danzhou CPPCC National Committee

sequence Reply to proposal 245

?

Dear member Yao Yunqin:

Thank you very much for your concern and support for the development of new energy heavy trucks in our city., you put forward at the first meeting of the 11th CPPCC Danzhou. Proposal No.245, after study, we hereby reply as follows:

First, the development status of new energy heavy trucks in Danzhou City

The development of new energy replacing electricity and heavy trucks with heavy trucks.The construction of (charging) power infrastructure and the operation of heavy trucks for power exchange are the core.At present, there are heavy trucks in operation in our city. There are 36 vehicles and 50 special commercial concrete vehicles for power exchange. Two heavy truck power exchange projects have been completed and put into use at the end of January 2022.Pure electric heavy truck power station replacement project of Yangpu International Container Terminal, invested and built by Guodian Power Investment (Hainan) Energy Service Co., Ltd., a subsidiary of Hainan Branch of State Power Investment, is built in Yangpu International Container Terminal Port according to the eight-station heavy truck charging and replacing power station, with a construction scale of 1250kVA, and a newly-built pre-installed 10kV, 1250 KVA box-type substation is connected by the 10 kV Shovel Line of South Power Grid. It is equipped with 8 chargers, 7 for operation and 1 for standby, with a total power load of 150kW. It is equipped with 35 vehiclesPower-changing heavy truck43 sets of 141kWh batteries. The power station has the characteristics of high efficiency, cost reduction, flexibility, safety and environmental protection: high efficiency is reflected in the fact that it can supply vehicles with energy for 6 minutes and solve mileage anxiety; Separate sales of vehicles and electricity, greatly reducing the cost of car purchase; The battery packs with different electric quantities can be flexibly replaced according to the working conditions, thus reducing the self-weight of the car body; The centralized management of charging is safe and controllable, which prolongs the service life of the battery and improves the utilization value of the battery.

The other is Hainan Yangpu Ronghe Junchi Landao Power Station Exchange Project., the first electric heavy truck charging and replacing power station in our province, invested and built by Hainan Yangpu Ronghe Junchi Technology Co., Ltd. (hereinafter referred to as Ronghe Junchi), located in the factory area of Hainan Landao Environmental Protection Industry Co., Ltd., Mutang Park, Danzhou Industrial Park, with an area of 10 mu. The power exchange station is constructed in two phases, including 2 power exchange stations, 2 2000KW transformers, 50 heavy-duty trucks and 57 sets of 282kwh batteries. The power exchange station and batteries are put into operation in 60 phases in five years. In the first phase, a 2000 kW transformer, a power station and 30 parking spaces were laid. In the second phase, a 2000KW transformer and a power station were laid. At present, the infrastructure of the first phase of Landao Power Station (NO.001) has been completed, which also has the characteristics of high efficiency, cost reduction, flexibility, safety, standard and intensive.

Second, the demand for the construction of new energy heavy trucks in Danzhou City

According to Hainan Provincial Department of Industry and Information Technology The Implementation Plan for the Pilot Application of New Energy Vehicle Switching Mode in Hainan Province issued in November 2021 (Qiong Gongxin Automobile [2021] No.195) and "Guiding Opinions of Hainan Province on Supporting the Construction of Electric Vehicle Switching Stations"(Qiong Fa Gai Energy Letter [2021] No.513) requires giving priority to pilot projects in Haikou, Sanya, Danzhou Yangpu, Qionghai, Wanning and other regions to build a new energy vehicle power exchange network with reasonable layout and moderate advance.

Huanxinyingwan District with Yangpu as the industrial center in our city.Industrial development has a certain foundation.The orientation of industrial development is relatively clear. Take Xiaochantan Wharf and Yangpu Port as radiation centers.Through Hainan West Line Expressway, Wanyang Expressway, Danbai Expressway and Haiyu West Line.(G225), heavy truck freight can radiate the whole island.

Developing clean energy heavy trucks is the need of industrial development.From the perspective of Yangpu Economic Development Zone,With the development of olefin industrial chain in petrochemical functional zone and the extension of aromatic industrial chain to high added value.In recent years, a large number of petrochemical projects, such as millions of tons of ethylene and PTA and PET expansion projects, have been put into production, and the radiation from the port to the petrochemical functional area will surge. According to incomplete statistics, the annual demand for standard containers in the petrochemical functional area will surge from 12,000 to 15,000 to more than 30,000 TEUs every year, and the electric transformation of short-distance transportation within 100 kilometers has obvious advantages.

Heavy trucks with electricity exchange have the advantage of short-distance transportation cost, in view of the current ordinary chaika transportation.The transportation cost of each standard container within 100 kilometers is 400 to 420 yuan, and the liquefied petroleum gas or methanol after cleaning transformation is about 200-220 yuan; Pure electric heavy trucks are transported in 180-200 yuan each.

It is necessary for the development of the park to promote the replacement of heavy trucks.With the in-depth integration of foreign integration,The foundations of two areas of Danzhou Industrial Park, Mutang and Wang Wu, are under rapid construction.The healthy food processing and high-end manufacturing industries in Yangpu Economic Development Zone have developed rapidly.Driven by the development of the park, the demand for heavy truck transportation such as container trucks and commercial concrete has surged.

Popularizing heavy trucks for power exchange is the demand of infrastructure construction.With the implementation of the expansion plan of Xiaochantan WharfPort container throughput can be doubled from the current 1.5 million standard containers. With the demand for infrastructure construction such as road network and hospitals around Xinyingwan District, the demand for heavy truck transportation of commercial concrete is increasing.

Popularizing the construction of heavy truck-to-power station can solve some energy storage needs of offshore wind energy development.From next year, with the development of three nearly 350MW wind fields in CZ2-4 in the northwest of Danzhou, the heavy truck power station can solve the energy storage function of some offshore wind power because of its strong energy storage capacity and great adjustment of power supply peaks and valleys.

Three, to speed up the city’s heavy truck power exchange project construction plan

In the past two years, it has been affected by the epidemic and the growth rate of upstream and downstream industries of real estate has slowed down.The impact has brought adverse effects on the development of new energy-replacing heavy trucks. The Municipal Bureau of Science, Technology and Information Technology will, in accordance with the "New Energy Storage Development Plan of Hainan Province in the 14th Five-Year Plan" of the Provincial Development and Reform Commission and the requirements of the city on the development plan of charging and replacing infrastructure, the implementation plan and work plan over the years. Combined with the characteristics of Danzhou Yangpu’s economic and social development, driven by the strong demand of clean energy substitution, short-distance electrification and intelligent development, during the Tenth Five-Year Plan period, we will further vigorously promote the construction of pilot projects for replacing electric vehicles with electricity, build an application and service guarantee system for the construction of electric vehicles in the industrial field, and focus on promoting the construction of heavy trucks for power stations.

Continue to use existing pilot resources.To promote the application of new energy in the industrial field. Do a good job in the promotion and replication of the power exchange mode and service guarantee system of electric heavy trucks in the area around Xinyingwan, strive to complete the electrification replacement of motor vehicles in key terminals during the 14 th Five-Year Plan period., the pilot construction of concrete transportation system for electricity exchange in Huanxinyingwan District., continue to declare the construction of provincial and national pilot cities for power exchange, and strive to establish and improve smart ports and smart logistics systems.

In summaryIn accordance with the work arrangements of provinces and cities, we will continue to unite with relevant departments to speed up the application and promotion of replacing heavy trucks and the construction of heavy truck power exchange projects. Once again, I sincerely thank you for your concern, support and supervision on the development of new energy heavy trucks in our city.!

November 7, 2022

I know some good news recently, and Dr. Tao wants to share it with you quickly. A definitive conclusion based on these good news is:

Quadruple (DTP +Hib) vaccine+domestic inactivated polio vaccine (IPV)

The price/performance ratio is getting higher and higher. It smells good.

Since 2002, Dr. Tao has collected all kinds of domestic vaccine products, coded and photographed them, and unconsciously built the China Vaccine Museum.

This vaccine museum is located in the vaccine science popularization base in Kangtai, Shenzhen. Crucially, Dr. Tao is still tirelessly collecting new vaccine products to contribute to this museum.

Vaccine Museum at No.18 Shutianpu Road, Shenzhen

Not long ago, Dr. Tao just collected the third domestic IPV from Kexing Bio. The first two paragraphs are from Institute of Medical Biology (Academia Sinica) and Beijing Beishengyan Biological Products Co., Ltd. (Beishengyan). In this way, with the import of IPV from Pasteur, there are four IPV models in China.

I accidentally compared the instructions of four IPV companies and made my first major discovery. However, we need to popularize the common sense of polio vaccine first.

The polioviruses used in two domestic IPV come from live oral vaccines. The vaccine virus in oral live vaccine is also called sabin strain virus, so domestic IPV is also called Sabin IPV(sIPV). The polio virus in Pasteur IPV comes from wild virus, also known as WIPV.

Before sIPV came out in China, the single inactivated polio vaccine was all wIPV. However, the use of wild viruses in wIPV production requires the highest biosafety level in vaccine workshops, and the possibility of polio epidemic caused by leakage into the environment cannot be ruled out.

IPV is a good thing, and China also wants to replace the oral live vaccine with major defects for all children (see:The way to avoid the devil’s lottery and vaccinate polio safely）。 However, China has a large population, and IPV is many times more expensive than oral live vaccine. If IPV can be localized, it will be much easier.

Just do it. Academia Sinica, which produces oral polio live vaccine (known as "sugar pill" vaccine), took the lead. In order to reduce the construction cost and biosafety risk, they found another way to directly inactivate the virus in the live vaccine to make IPV, and sIPV was born in the world. Beishengyan and Kexing Bio have reached the next level, and domestic sIPV imports wIPV three to one PK.

However, whether wIPV is better or sIPV is a difficult question to answer at first, but with the two IPvs used in China for 10 years, some data began to surface or be confirmed.

At first, Dr. Tao thought that although the virus sources were different, there was no substantial difference between them, and even they were winners and losers. But this time, after carefully reading the instructions of the three companies, I found a common phenomenon:The antibody levels of three sIPV in clinical trials are much higher than those of wIPV.I’m a little embarrassed that I didn’t notice this before.

See the table below for specific data. The third dose of basic immunity refers to one dose at 2, 3 and 4 months old, and the first dose of additional immunity refers to the fourth dose at 18 months old. Fourteen months after the third dose of basic immunization refers to the blood sampling test before the fourth dose.

For three types of poliovirus, the antibody levels of three domestic sIPV were higher than those of imported wIPV as control group at any time point, and the antibody level of type I virus was more obvious. The number of observers in these clinical trials is about 300 ~ 600, and the sample size is large enough to be an error.

Dr. Tao can say with certainty that the short-term immune effect of domestic sIPV is better than that of imported wIPV. Of course, the immune effect and protective effect are not the same thing. In fact, imported wIPV has been used outside China for more than half a century, and there is no evidence that its protective effect is unreliable, so there is no need to abandon wIPV.

This week, Dr. Tao saw that the Chinese Academy of Sciences published the 10-year observation results of sIPV and wIPV in eClinicalMedicine, a sub-journal of The Lancet, which was the final word.

10-year observation results https://t.cn/A6OENJOH

It can be seen that after 10 years, the antibody level of sIPV is also higher than that of wIPV. Inferred from this trend, the high probability will be the same after 20 years, at most, it will be flat, and it is impossible for the antibody level of sIPV to be lower than that of wIPV.

There is no doubt that sIPV’s immune effect is better than wIPV’s in both short and long term.

The above is the good news that Dr. Tao wants to share with you.

In order to prevent polio, diphtheria, pertussis, tetanus and Haemophilus influenzae (Hib) infection, every child should be vaccinated with three kinds of vaccines: polio vaccine, DTP vaccine and Hib vaccine.

There are many permutations and combinations of these three vaccines, and Dr. Tao once recommended using five vaccines directly. However, the cost performance of this scheme has dropped a lot, and the cost performance of [quadruple vaccine+domestic IPV] scheme is getting higher and higher because of the following two reasons:

First, four doses of polio vaccine are required, and the government can provide two doses of domestic IPV free of charge.

If you use pentavaccine, you can’t enjoy this free policy, because the price of pentavaccine includes imported IPV. Enjoy 2 doses of free domestic IPV, at least you can save 540 yuan. In 2023, the supply prices of five vaccines and four vaccines are 638 yuan and 368 yuan respectively, which is different from 270 yuan. Multiplying two doses is 540 yuan.

In the future, all 4 doses of polio vaccine will definitely be changed to 4 doses of free domestic IPV, and then 1080 yuan can be saved, which will be too fragrant.

Second, the five-vaccine is wIPV, which is not as fragrant as sIPV. The evidence is conclusive.

Of course, the five-vaccine also has an advantage at present, that is, it can be vaccinated at the age of 2 months, one month earlier than the four-vaccine, and protected earlier. Therefore, you can also choose five vaccines at the age of 2 months, and then choose all [four vaccines+domestic IPV].

　　Beijing nucleic acid detection "long queue" citizens: once ate near the restaurant with confirmed cases.

　　Sino-Singapore Jingwei client June 19 (Zhang Yanzheng) "Keep your distance, one meter apart, and please line up at the back for those who do nucleic acid testing." Three uniformed security guards said to the person who just came to test. On the morning of June 18th, the reporter of Zhongxin Jingwei noticed that there were two long queues at the entrance of a physical examination center in Chaoyang District, Beijing, even at the entrance of the corner cafe, with about 30 people in each queue. In addition, a guidepost of "nucleic acid detection" was placed at the intersection of the physical examination center.

　　With the escalation of epidemic prevention and control in Beijing, many citizens made an appointment for nucleic acid testing as required. Recently, Zhongxin Jingwei reporter interviewed several citizens who made an appointment for nucleic acid testing and listened to their reasons and experiences of doing nucleic acid testing.

　　"Leaving Beijing requires a negative nucleic acid certificate within 7 days"

　　Mr. Li Internet Industry, Chaoyang District, Beijing

　　At 9: 00 am on June 18th, when Mr. Li came to the entrance of a physical examination center in Chaoyang District, Beijing, there was already a long queue of nearly 50 people in front. He couldn’t help but sigh that "I didn’t expect so many people to do nucleic acid testing" and picked up his mobile phone and took a live photo.

　　Mr. Li said that due to the nature of his work, he needs to travel frequently. According to the work plan, he should fly from Beijing to Shenzhen on the evening of June 18 to participate in the following week’s project activities. However, the day before departure, I checked the news and found that I need to hold a negative nucleic acid certificate within 7 days to leave Beijing.

　　It is understood that Beijing announced on the evening of June 16 that the emergency response level of public health emergencies was adjusted from level 3 to level 2. Subsequently, Chen Bei, Deputy Secretary-General of Beijing Municipal Government, said at the press conference that under the second-level response, the relevant personnel in the middle and high-risk street towns and Xinfadi markets were forbidden to leave Beijing, while other personnel insisted on "not leaving Beijing unless necessary", and those who really needed to leave Beijing must hold a negative nucleic acid test certificate within 7 days.

　　Photo courtesy of public respondents who made an appointment to queue up for nucleic acid testing.

　　"After seeing the news, I quickly reported to my boss, and the date of meeting with the customer was postponed for five days. Then, I made an appointment for a nucleic acid test by phone to test a 260 yuan. " Mr. Li smiled. "Fortunately, I don’t live in a high-risk area, otherwise I wouldn’t be able to leave Beijing at all." He said that the plane ticket has been unsubscribed, and the human resources department of the company will be notified to re-book the plane ticket after the nucleic acid test results come out.

　　However, what worries Mr. Li is that the results of this nucleic acid test may come out slowly. "The nurse in the physical examination center said that there are a lot of people who have done nucleic acid testing recently, and the specific time of the results cannot be guaranteed. It may take two or three days, or it may take four days. You don’t need to come to the physical examination center to get the report. You can query the nucleic acid test results through the the State Council client applet."

　　"Passing through high-risk epidemic areas"

　　Ms. Wang, an employee of a state-owned enterprise in Dongcheng District, Beijing

　　At the entrance of the physical examination center, Ms. Wang ranked in the front position and was one of the first people to finish the nucleic acid test. Ms. Wang introduced that she had been waiting in line at the entrance of the medical examination since 6 am. "I was passing by the Xinfadi market, so the doctor asked me in detail, but the whole testing process was very fast. The doctor took a special cotton swab and dipped it into his mouth to take some secretion-like things, and the sampling was only a few minutes."

　　Appointment personnel fill in the "Personal Commitment Letter" in the new Jingwei Zhang Yanzheng photo.

　　Compared with completing throat swab sampling in a few minutes, Ms. Li said that the process of making an appointment for nucleic acid testing was "too difficult".

　　From the WeChat notice displayed by Ms. Li, the reporter of Zhongxin Jingwei saw that this message, which was sent on June 16, said, "In order to meet the requirements of epidemic prevention work in Beijing, we are now comprehensively screening related personnel such as Xinfadi, Yuquan East Vegetable Market and Guangwai Tiantao Honglian Vegetable Market. If you have been to the above vegetable markets from May 31 to June 15, please cooperate with the registration or reply to the information."

　　Ms. Li introduced that at the beginning of June, she passed by the vegetable wholesale market in Xinfadi by bus. For safety reasons, she reported this situation to the unit, and then she was suspended from work by the unit and asked her to go to the hospital for nucleic acid testing as soon as possible. "On June 16th, I called several hospitals that day to make an appointment for nucleic acid testing, but the designated hospitals in Beijing were already full that day and needed to wait for four or five days, while the Ciming Health Physical Examination Center only received group nucleic acid testing. Finally, I found this physical examination center for personal testing, but it was also three days later."

　　"I used to eat near the restaurant where the case was diagnosed."

　　Mr. Chang’s Media Industry in Fengtai District, Beijing

　　Mr. Chang, who lives in Fengtai District, Beijing, is considering doing nucleic acid testing in the near future. Mr. Chang introduced that he had eaten in a restaurant in Fengtai before, and next door to this restaurant was the Sichuan restaurant where five waiters had been diagnosed.

　　It is understood that on June 14th, Beijing announced a confirmed case of a restaurant employee. The waitress worked in the Li Ji Sichuan Shoujingmao Store near Huaxiang Shoujingmao in Fengtai. It is reported that the waiter and the chef went to Xinfadi market to buy plates on June 4. On the evening of June 16th, Beijing CDC released a message again, saying that among the newly diagnosed people that day, four newly diagnosed people were close contacts of the confirmed female patients announced two days ago. In other words, all five employees of this Sichuan restaurant in Fengtai, Beijing were diagnosed.

　　Mr. Chang said that on June 4th, the waiter of Sichuan Restaurant went to Xinfadi Market, and he and his friends went to the restaurant next to this Sichuan Restaurant for dinner on June 5th. "In the past two days, my friend just did a nucleic acid test, and the result was negative. Today (June 18), my community organized a free nucleic acid test. In order to reassure myself and consider the safety of friends and colleagues, it can be more reassuring to do a test."

　　"I came back from Beijing and was asked by the community to do the test again."

　　Zheng Yu (pseudonym), a job-seeking student in Shantou, Guangdong.

　　Looking back on the experience of going to Beijing this time, Zheng Yu never thought that it was just her two days in Beijing that Beijing suddenly announced the emergence of local cases. Later, she had to do two nucleic acid tests after returning to Guangdong.

　　On June 10th, Zheng Yu, who just graduated from college this year, came to a company in Beijing for an interview and written test, and returned to Shantou, Guangdong on the afternoon of the 12th. As the interview unit is in Xicheng District, Beijing, she booked a hotel near the company and rented it for two nights.

　　Unfortunately, it was just these two days when I came to Beijing for an interview that Beijing announced the escalation of epidemic prevention and control. It is reported that on June 11, Beijing reported a new confirmed case in Xicheng District, and on June 12, another 6 cases were confirmed in Beijing. The sudden rebound of the epidemic also worried Zheng Yu’s family and urged her to pay attention to protection and go home early.

　　For safety reasons, Zheng Yu, who has returned to Shantou, decided to do nucleic acid testing. On the morning of June 15th, Zheng Yu did a nucleic acid test in the First Affiliated Hospital of Shantou University School of Medicine at the expense of 75 yuan. "When I was ready to see the test results the next day, I felt very nervous, as if I had experienced the second college entrance examination, because many people around me were paying attention to the test results, but fortunately the results showed negative."

　　With the development of community screening, on June 18th, Zheng Yu received a phone call from a local community worker, and the other party said that people who came back from Beijing needed a second nucleic acid test after 14 days of home isolation. (Zhongxin Jingwei APP)
