"Well, don't lose heart. I think you have a chance this year!" Yan Shumin leaned out his neck from behind and said, "no matter you can't find a boyfriend, at least you have a chance of promotion this year. You see, the director has sent you and me to attend the lecture, indicating that the above has started to identify with your work ability..."

The morning lecture is at the Medical University in s city.

When Nie Xiangsi and Yan Shumin sat in the conference room of Nuo University and saw the foreign professor together with many people from other hospitals, they were shocked!

"Depend on it!" Yan Shumin desperately shook Nie's arm and became a narcissist. "Lovesickness, tell me quickly. In fact, the hospital has realized that we, the elderly single women, are bothered with our brain. It specially sent us to listen to the lectures of handsome professors and want to help us win opportunities, isn't it?"

Nie Xiangsi blinked, "this Can't you send us to fight with more than 100 people? "

In the surrounding conference room, there were more than 100 doctors and nurses who came to listen. The unmarried nurses in the room were almost crazy about the young mixed race professor in front of them!

"I don't care. This is my sister's dish!" Yan Shumin gnashed his teeth and said, "Acacia, after the lecture, you will accompany me to talk to him!"

"Ah? This... " "Nie Xiangsi is silly," isn't it too abrupt

In front of him, the gentle young professor in the lecture was a Chinese Korean mixed race. He was of considerable height and stature. He had a handsome Chinese face like a Korean actor, a shirt and trousers, a tie, and a white coat of scientific researchers outside!

Elegant and handsome, with outstanding temperament, gentle voice and penetrating power!

"Let's start with an introduction." The language of his country Z is very proficient. "My name is Han Ziqi, Chinese and Korean nationality, 28 years old. I am currently engaged in the research center of life gene science in onor, USA. I am employed as a visiting professor in more than ten national medical universities. You can call me Professor Han. I have been engaged in the research of life, gene and human body for many years. Welcome to discuss it with my peers..."

Yan Shumin covered her mouth and smiled at her low aunt, "the study of human body How can it sound so green? "

"Your mind is blue." Nie Xiang Si Tucao Dao, "make complaints about your medical career."

"However, at the age of 28, he is a member of the ONO Center for life and gene science, and his achievements are too high." Yan Shumin shook her head and admired, "that's the most authoritative life gene research center in the world!"

Later in the lecture, the professor from the ONO Center for life gene research in the United States talked about blood group As we all know, the common blood types in the medical community are ABO and ab punishment. In addition to these four blood types, the rarer one is Rh negative blood, which is called Panda blood. "

His clear voice circulated in the air along the microphone, "but the rarity of Rh negative blood is only compared with the common blood type, which accounts for 15% of the white people, so according to the population base, it can not be said to be very rare. Especially compared with the following four rare blood groups, it is not rare. In addition to Rh negative blood, there are four rare blood groups in the world at present. "

" the first one is Bombay blood. There is anti-H antibody in this blood serum, which makes it very difficult for patients of this blood group to receive blood transfusion in clinical practice. In general, they can only receive blood of the same type and self transfusion. "

"The second type is p blood. According to statistics, there are only 9 people with this blood type in country Z, less than one thousandth of panda blood."

"The third is the rhunll blood group, which is currently only 43 cases in the world. It is a real universal blood group, commonly known as golden blood. This kind of blood can be delivered to any kind of rare blood group. For the patients with Rh negative panda blood, Mumbai blood and P blood, rhnull blood is the life-saving straw when they cannot find the same type of blood.

At present, there are less than six donors of rhnull blood group in the UK's international blood bank. Such blood group patients can only receive blood transfusion of the same blood group, and women with this blood group may not be keen on Breeding for a lifetime. "

A male intern raised his hand.

"Please." Professor Han showed off his hand to the intern.

The male intern stood up and said, "excuse me, Professor Han, why are rhnull blood type women not keen on breeding? What's the reason?"

Han Ziqi asked him to sit down and said, "it's very simple, because when a rhnull blood type woman is pregnant, her blood will exchange antibodies with the blood of her fetus. Once rhnull antibodies are produced, she will have hemolytic reaction with her fetus when she is pregnant with a second child, which is life-threatening. So rhnull blood group women can only have one child at most in their lifetime. "

Nie Xiangsi, who is taking notes like other people, was stunned and stopped writing.

She thought of her mother and her gambling father.

According to her mother, her father wanted to have another son, regardless of her mother's life.

In the surrounding exclamation, Nie Xiangsi continued to scribble and take notes.

Another female nurse raised her hand. "Professor Han, didn't you just say that there are four blood types that are rarer than panda blood? What kind of blood is there? "

"Thank you for your warning, or I'm afraid I won't talk about the last blood type." Han Ziqi said with a smile, the whole person with a kind of gentle temperament, caused the love of countless female nurses.

Being called a beauty, the face of the nurse just now turned red.

In the laughter of the female nurses at the scene, Han Ziqi continued, "I'm afraid I won't talk about it because the last blood type is even rarer than rhnull blood, and there is no chance to study it at present. The medical community named it as" B3 subtype ". This is an extremely rare case found in country Z more than 20 years ago. There is only one person in the world, and it is a gene mutation after testing Change, but the information of the blood group is not disclosed... "

After the lecture, Nie Xiangsi and Yan Shumin walked out of the conference room together, and Yan Shumin shook his head all the way.

"In the early years, panda blood was extremely rare for ordinary people. An aunt in my hometown was of this blood type. My uncle loved his daughter-in-law and said that he would not have children with my aunt." Yan Shumin said, "now it seems that there are all kinds of wonders in the world, and those rare blood types are unimaginable!"

Nie's surprise was a little hard to understand. "I've heard of it before. There are several rare blood types in the world."

"Before listening to Professor Han's lecture today, it was not so clear!" Yan Shumin kept the worship of Professor Han just now. "Besides, I was forced by my family to take the entrance examination to the health school. I didn't learn from you. Did you know about blood type long ago?"
