In the whistle of the steamer, a small inland steamship of about 40 tons slowly approached the pier of Hengyang Steamship Bureau. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoAt this time, the sunrise in the east, with the red morning glow, actually has a blood-colored splendor.

Wu Xinglian, who had been traveling all night, came to Hengyang early in the morning - this is the epidemic area closest to the north, at this time the city has been completely isolated, the army and military police not only guard the city, but also defend the road through the place, in order to avoid the further expansion of the epidemic, no one is allowed to enter or leave here without a special pass issued by the General Administration of Epidemic Prevention

After arriving in Hengyang, Wu Xinglian did not rest, but prepared for the next experiment, and there were test materials prepared for him by others in the room, and there were several flat-bottomed beakers.

"Although it is a little higher, I will use this for cultivation for the time being...... Petri dish bar......"

After inadvertently popping up such a term in his mind, Wu Xinglian drew the shape of a "petri dish" (1) on paper, if it was really as he speculated, perhaps future experiments would not be able to do without this simple glassware with a lid.

After Wu Xinglian prepared everything, he couldn't help but look out the window and saw a carriage galloping towards him, stopping at the door of the hotel, and a doctor in military uniform jumped down from the carriage and rushed into the hotel.

Wu Xinglian turned around and walked out of the room, knocking on the door of his student Lin Jiaming:

"Jiaming, it seems that there is a rest, ready to go."

The medic ran upstairs panting and reported that a patient had just been in the isolation hospital.

Wu Xinglian hurriedly asked:

"What about the patient's family? Have they been notified? ”

The military doctor immediately replied:

"According to your order, the gendarmes have sent people to strictly protect the patient's house from idlers, and Dr. Yang is guarding there and has not yet informed his family."

Wu Xinglian nodded hurriedly:

"Okay, go there right away." ”

He and Lin Jiaming quickly came to the isolation hospital with the military doctor who led the way. This is a newly built primary school in Hengyang City, which has not yet been put into use and is used as an isolation hospital.

"The deceased coughed up blood and died last night."

In the introduction of other military doctors, Wu Xinglian examined the patient's body, and judging from the physical symptoms, he did die of the plague. Then he immediately ordered all the people to withdraw, ordered the gendarmes to cordon off the scene, no one was allowed to approach, and after a simple disinfection of the hut, Wu Xinglian took out a mask and put it on, and after bringing surgical instruments, he and Lin Jiaming were about to go in.

Dr. Yang hurriedly asked:

"Sir, what are you?"

"Dissect the corpse!"

Wu Xinglian replied briefly.

"But this ......"

Doctor Yang looked at the chief medical officer with some surprise, although he was no stranger to autopsies, but he knew very well that autopsies were not generally accepted in China, although the Ministry of War had already issued autopsy regulations, allowing autopsies "based on the learning needs of military doctors". However, in such a situation, if the autopsy is carried out, it is very likely to cause civil unrest, after all, the people will not necessarily come into contact. Moreover, the dissection of the corpse of the deceased is likely to be infected with the emaciation plague, and everyone knows that the plague will kill those who are infected.

Dr. Yang quickly dissuaded:

"Chief Medical Officer, please think again!"

Shaking his head, Wu Xinglian said:

"I know what I'm doing, and I'll take care of everything."

After that, he walked into the house first, and Lin Jiaming followed closely.

Everything is just speculation, in Wu Xinglian's flash of speculation, he believes that if a person dies because of plague, then there will naturally be a large number of "plague bacteria" in the patient's body, and it is very dangerous to dissect. However, in order to understand the cause, it must be done. And more importantly, it has the potential to save a lot of people.

When he came to the patient's corpse, everything was arranged, Wu Xing and Lin Jiaming said:

"Are you ready?"

Lin Jiaming nodded a little nervously.

Wu Xinglian added:

"Be careful."

With that, he cut open the skin of the deceased.

In the dark corner, blood slowly flowed from the tip of the knife......

On January 7, 1857, in this faculty office in Hengyang, Wu Xinglian performed the first off-campus human anatomy. The patient's blood, lungs, spleen, and liver were taken out separately, put into culture or soaked in formalin, and then the skin of the deceased was re-stitched, and then he would be cremated and buried, which is why he was asked whether his family should be informed - everything had to be done quietly, after all, the people were resistant to autopsies, and this was the same as the military department required that autopsies should be carried out in military medical schools.

Wu Xinglian then ordered the room to be thoroughly disinfected. Then ask Dr. Yang to find a room in the isolation hospital. An empty room was prepared and disinfected, and after the disinfection, Lin Jiaming placed the microscope and other experimental equipment there, which was regarded as a temporary laboratory.

After the patient's organs were fixed with formalin, Wu Xinglian immediately took a section, then looked at it under a microscope, and soon he identified a strain from the organ section that was different from the normal cell.

"Jiaming, Doctor Yang, come and see."

He pointed to the microscope and said:

"There is an abnormality in the organ, but if I am not mistaken, it is very likely to be the culprit of the plague!"

When he said this, Wuxing Cotton didn't know what he had created at this moment. But he knew very well that his guess was correct, and it was very likely that he would use it to solve the problem.

The two of them were very excited after reading it, as doctors, they naturally understood what this meant, which meant that the doctor had opened a new chapter, Lin Jiaming hurriedly asked:

"Teacher, what now?"

Wu Xinglian frowned tightly and said:

"Now we have to wait for the culture of the blood samples, and we have to get live samples before we can draw conclusions. If all this can be confirmed...... Perhaps, we can fight the plague! ”

It's time to come down within two days. While waiting for the results of the sample culture, Wu Xinglian and Lin Jiaming conducted a careful study of the patient's various organs, which fully proved the existence of Murine Liquid Bacillus.

Two days later, a cluster of Y. pestis appeared on the medium, indicating the presence of live bacteria in the patient's blood.

Everything is confirmed, so what's next?

In the following period of time, Wu Xinglian continued to conduct experiments, as the chief medical officer of the General Administration of Epidemic Prevention, he devoted all his energy to the development of vaccines, and he did not choose the more virulent live Yersinia pestis, but chose dead strains to prepare vaccines. After discovering that Yersinia pestis could grow in nutritious broth, he immediately injected rabbits with a high-temperature inactivated broth culture to protect them from Y. pestis.

By the end of January, the plague death toll had climbed to 60,000. Because of this, he immediately decided to have a doctor give him an injection, and there were no adverse effects except for local pain and increased body temperature.

In the early morning of the next day, that is, on January 29, Wu Xinglian reported his vaccination process and reaction to hundreds of doctors and military commanders who participated in the epidemic prevention, and recruited volunteers to be vaccinated, and immediately received everyone's response, and on the same day, 476 people who participated in the epidemic prevention were vaccinated.

Two days later, the vaccine was sent to Yongzhou, the worst hit area, and trials were conducted in specific areas of the worst hit on the same day.

In the hardest-hit area, known as Pilot Zone 1, which had a pre-pandemic population of more than 5,000 people, less than 3,300 people remained, and more than one-third of the population died from the plague.

On the day of vaccination, the plague-stricken people gathered in the streets, with half of each household vaccinated and the other half not vaccinated as a control group. For these people, they don't know what the doctor is doing, and in the fear of death, they can only accept everything helplessly.

It's a gamble!

No one knows what this mass vaccination will bring, and likewise no one knows if the vaccine will really work, but everyone knows very well that this is their last chance.

As the chief medical officer, Wu Xinglian has been following the situation there since the start of vaccination trials in various places. Every day, he would personally go to the mailroom and wait for reports from all over the country, and then make the reports himself.

"Of the 1,514 people vaccinated in Pilot Zone 1, 13 died on the same day, and no one died for the next six days. Of the 1,647 unvaccinated, 19 died on the same day, and 97 died in the following six days. No. 2 Experimental Area...... The effectiveness of vaccines in preventing plague has been preliminarily confirmed......"

There is no doubt that the experiment was successful, and Wu Xinglian, as the general hospital of the General Hospital of the General Administration of Epidemic Prevention, couldn't help but breathe a sigh of relief, and now he can finally face those people. While vaccines can't save people who have already been infected with plague, they can at least keep those who haven't been safe.

"The only problem now is the ...... of production"

Although he knows that with the current production, the vaccine is far from meeting the needs of millions of people, Wu Xinglian, as an epidemic prevention expert, knows very well that the limited number of vaccines used in high-risk areas and high-risk groups is enough to control the current situation, at least so that it will not spread further.

"To set up a laboratory ......"

After drafting a long telegram to the governor's office about the epidemic, Wu Xinglian put forward his suggestions in the long telegram, and his suggestions were very simple.

"In addition to the establishment of an infectious disease laboratory in Wuchang, a corresponding small laboratory should be set up in each province and prefecture, and the doctors in the laboratory should receive basic epidemic prevention training to avoid a similar outbreak of infectious diseases......"

If the outbreak of this epidemic has made Wu Xinglian aware of anything, I am afraid that it is aware of the need to establish a response mechanism to ensure the physical safety of the people......

“…… The government should provide sufficient funds for epidemic prevention research! ”
