When Sun Lien got up, he still felt a sense of omen in his legs and stomach. Hu Jia's subsequent words last night made him feel a little apprehensive now.

In the future, if you have to eat with your father-in-law...... Why don't you take two cephalosporin tablets in advance?

This concern persisted until he got into his buggy and prepared to set off for a Katu village 48 kilometres away.

Sitting in a car with Sun Lien was Qian Yihong, the female gynecology doctor who met yesterday. Not long after the car started, Sun Lien noticed that Qian Yihong had been holding up his mobile phone and looking at a photo on the screen.

It was a photograph that I don't know how many times it had been taken out and looked at repeatedly, and although it was in color, the quality of the image with a particularly sense of age, coupled with the marks of wear and tear and folding, all showed the long history of the photograph thirty years ago.

There are two people in the photo, one is a young girl, wearing a very old white coat and a white hat on her head, looking like a quarantine officer in a veterinary office. Although he is young, his face is very unsightly. It seems that the pallor after recovering from a serious illness and extremely unhealthy jaundice are mixed together, how to look at it makes Sun Lien feel worried.

Next to the little girl stood a tall, thin black man. She was also a woman, and she was holding a child about four or five months old in her right hand.

"It's ...... Your previous photos?" Sun Lien looked at it for a long time, and finally found a little similarity with Qian Yihong on the face of the little girl with a very ugly face. "You've been to Africa before?"

"That's right. Qian Yihong put down her phone and laughed. "I'm still your predecessor – the first time I came to Africa was in Mali in '90, and it was already the second batch of medical teams. ”

"Then why are you still coming to Africa now?" Sun Lien was a little curious when he heard this, "The hospital selects medical team members to aid Africa, and basically only selects doctors who have not yet come, right?"

"When I come to Africa in the future, I will do it voluntarily. Qian Yihong's head raised slightly, she looked at the African sky outside the window with some nostalgia, and told the story of more than 30 years ago.

More than 30 years ago, after arriving in Polytavia as a member of the second medical team, Qian Yihong, a junior gynecologist, fell ill with malaria, the most dangerous form of falciparum malaria, on the third day after the plane landed.

At that time, there were not many ways to treat falciparum malaria, mainly relying on chloroquine and several other quinine drugs. But these drugs have never worked well on Qian Yihong's body. After more than a week of delays, the leader of the medical team saw that Qian Yihong's condition was getting worse and worse, so he decided to use the new drug that the team was carrying-compound artemether.

As a compound product of artemisinin, compound artemether can effectively solve the problem of rapid treatment of artemisinin but high recurrence rate. However, due to the lack of extensive patent registration in China at that time, through foreign drug effectiveness tests and commercialization experience, this new drug was only partially manufactured and used in China.

The medical team brought compound artemether to Polytavia, probably with the mentality of obtaining experimental data for a small range of experimental drugs. However, before they officially started the experiment, the drug was actually used by their own people.

After the use of compound artemether, Qian Yihong's malaria was quickly and effectively controlled. But unfortunately, falciparum malaria has too much damage to the body, and the delay has been a little long, and she has been in a state of severe anemia since then, and her physical condition is quite worrying. Although they hoped to give Qian Yihong a blood transfusion as soon as possible to alleviate her symptoms, at the stage of blood test, the doctors found that the young girl was actually type A RH negative blood - commonly known as "panda blood". None of the members of the medical team were equally rh-negative, and it was necessary to find RH negative blood type A in Mali, a mess with similarly weak basic medical care...... That's just impossible.

Just as the medical team and the embassy began to negotiate to send Qian Yihong back to China for further treatment, outside the Kadi Hospital where Qian Yihong worked, a large number of locals, most of whom were women, suddenly came.

They're here to donate blood.

One of the most important aspects of the work carried out by the first medical teams in Mali after arriving was the provision of obstetric and gynaecological services to the local population. During their two-year presence, the team delivered thousands of newborns to local residents. Before the team was deployed to the Carti hospital, the natural maternal mortality rate was as high as 14 per cent. During the two-year service period, the natural maternal mortality rate was reduced to less than 1 per cent.

Mali is a very underdeveloped region where women generally marry and have children before they reach adulthood. Many women who are about to become wives are just ignorant and helpless children before they give birth. The medical team staff who have been in China for a long time can not bear this, they take more care of these mothers, and at the same time actively promote relevant gynecological knowledge in the local area. To put it bluntly, the two years of the Chinese medical team in the region will affect the region's future for the next 20 years or more.

Residents were so grateful to the Chinese team that almost all the women who had given birth at the hospital couldn't sit still when they heard that some of the new doctors needed blood transfusions.

This is a very simple concept of good and evil, they are so good to us, we should also help the Chinese doctors when we need help.

These young mothers brought their children and even their husbands to donate blood. The locals, who believe that blood can be used to impose curses, have only one idea: you can draw as much blood as you want if you can help the Chinese doctors, even if the child is only a few months old, as long as you can use it.

Local doctors at Carti Hospital worked hard to soothe the agitated donors. The leader of the Chinese medical team has also made a decision to accept blood donations only from locals who are adults and meet the physical fitness standards.

A day later, three women who had been identified as having negative blood type A RH successfully made a blood donation. The red blood in their bodies was transfused into the body of Qian Yihong, who was also young. She quickly got better, and a week later, she took a photo with one of the women who was donating blood.

Qian Yihong kept this group photo by her side until she came to Africa again this time, because she was worried that the photo would be damaged, she asked her son to remake the photo into a digital version and put it in his mobile phone.

"Since that time, I have signed up for every medical team in Africa. After Qian Yihong finished telling her story, she said with a smile, "Counting this time, this is the fifth time I have come to Africa." ”

"You came here to meet the people who donated blood for you back then?" Sun Lien listened to this story and sighed with some emotion, "After so many years, have you found them?"

"I never had the chance to see them again, and I heard that they all emigrated abroad – their whereabouts are unknown, and they never saw each other again. Qian Yihong looked a little regretful, "However, seeing them again is not the main purpose of my registration." ”

"Then what is your purpose?" Sun Lien was a little in awe of the elderly gynecologist in front of him, "The conditions here are so poor, far worse than in China." ”

"Conditions in Mali were far worse than in China, and I didn't even see a single patient there, and I fell ill without delivering a child. Qian Yihong said seriously, "I didn't make any contribution to Africa, they gave so much to save my life - what else can I do? I can only do my best to repay them." ”
