Early the next morning, Yang Zhengang returned to the base, and Jiang Nan went to school in Qilin's car.

"I missed so much homework before, and Master told you to come over at night and let me make up for you." Qi Lin said.

"Oh!" Jiang Nan nodded, Yang Zhengang went back, she naturally wanted to go to Ji Xianlin's side to live, while making up classes, she also had to learn more pharmaceutical knowledge.

"How's the leukemia data going?" Qi Lin asked her, "Don't look at the third senior brother who is gentle and gentle on the surface, he is very rigorous and strict in medicine. ”

Jiang Nan nodded, "It's almost, I'll soak in the library when I have time this Monday, and I'll have almost everything I should master." ”

"That's good!" Qi Lin nodded, this junior sister doesn't have to worry about her studies, she will work very hard herself, in fact, sometimes he doesn't understand why she is working so hard, not at all like a girl of her age, she is trying a little too hard.

In fact, because Jiang Nan had a lot of things she wanted to learn in her previous life, she didn't do what she wanted to do, and she felt very regretful, and she felt that she had to learn what she should learn as soon as possible in this life, so that she would have more time to do what she wanted to do in the future, become an excellent surgeon, treat more people, and not let herself have any regrets.

On Wednesday afternoon, several students in the research group did not have classes, and Xu Yan took everyone to the hematology ward of the Affiliated Hospital of the Military Medical University.

The doctors and nurses there came over to say hello when they saw Xu Yan.

"Doctor Xu!"

"Hello Director Xu!"

Cheng Jing asked curiously, "Teacher Xu, are you the director here?" ”

"Yes, just appointed." Xu Yan nodded, "My main job is the attending doctor here, and the school is part-time." ”

I see, everyone nodded, yes, Mr. Xu came back from studying abroad, and his medical skills must be very clever, if he just became a teacher, it would be too wasteful.

Walking in the corridor of the ward, Xu Yan began to test everyone's homework.

"Who says what are the clinical symptoms of acute promyelogenous leukemia?" Xu Yan asked.

"The main symptoms are fever, fatigue, palpitations after exertion, sternal tenderness, pale skin and mucous membranes, skin bleeding spots and ecchymosis." Cheng Jing hurriedly answered.

Xu Yan nodded, Cheng Jing glanced at Jiang Nan proudly, he was robbed of the opportunity, see how you behave in front of Teacher Xu.

"Anything else?" Xu Yan asked again.

And also? Cheng Jing was stunned for a moment, she shouldn't have leaked back, right?

"There is also a mild enlargement of the liver and spleen, which often makes some doctors misdiagnose it as a disease of the liver and spleen." Jiang Nan added.

"Not bad!" Xu Yan looked at Jiang Nan approvingly and asked, "What is the main treatment now?" ”

Jiang Nan hesitated, because acute promyelomyelogenous leukemia was no longer an incurable disease in later generations, and there was medicine to treat, at that time, Mr. Zhang often carried a large bag of medicine to those poor countries in Africa, just because it was sold very cheaply in China.

The main drug is tretinoin, but it seems that it has not been developed at all at this time, so Jiang Nan can't say.

Seeing that no one answered, Li Jie said, "The main means now is chemotherapy, as well as methotrexate, cytarabine, dexamethasone and other adjuvant intrathecal injections. ”

"That's right, of course, there's another option, a bone marrow transplant, but it's also the hardest one. First, bone marrow transplantation is not easy to find a matching donor, second, it is expensive, and third, acute promyelomyelotic leukemia has a rapid onset, and many times the patient dies before waiting for a bone marrow donor. Xu Yan said.

Everyone was silent, and their hearts were a little heavy, yes, so it was urgent to develop a drug that could treat this leukemia.

Jiang Nan thought in her heart, she knew that the retinoids used in later generations were used, but she didn't know how this medicine was made. At that time, she just followed Mr. Zhang's doctor's instructions to give medicine to patients, and what diseases she ate and how to take them were all according to the doctor's instructions, and she naturally knew the name of the medicine when she took more, but she didn't know anything about the ingredients of the medicine.

When I arrived at the ward, I saw several children with acute leukemia lying on the beds.

Acute leukemia is a high incidence in children, because of genetics, environment, drugs, chemicals, radioactivity and other factors, the onset is urgent, difficult to treat, is a very dangerous disease.

There were four children in the ward, two of whom were only five or six years old, and two of whom looked like they were in their teens, but all of them were pale, bareheaded, with infusion needles in their hands, and their faces were in pain.

"Mom, I hurt!" Suddenly a little girl moaned in pain, her mouth open, and tears fell down like beans.

"Good daughter, where does it hurt, tell your mother!" The little girl's mother held the child's hand distressedly, her face was haggard, her eyes were black, her eyes were full of red bloodshots, it seemed that the child was sick and she had not slept well.

"Mouth hurts!" The little girl began to cry.

"Obediently, Mom will bring you water to drink." The little girl's mother said hurriedly.

"Don't drink, don't drink, it hurts even more." The little girl shook her head in pain.

"What then?" The little girl's mother also shed tears, "Why don't mom brush your teeth, you haven't brushed it for a few days, is it because it hurts?" ”

The little girl didn't know, just looked at her mother with tears in her eyes.

The little girl's mother went to find a toothbrush on the bedside table, poured cold boiled water, and prepared to brush the child's teeth.

"Stop!" Jiang Nan suddenly screamed and jumped her, and the water cup almost hit.

"I'm sorry sister-in-law, I scared you!" Jiang Nan said embarrassedly, in fact, he was a little anxious and loud just now.

"The child has mouth ulcers, which is a complication of leukemia, so the child feels pain. If you insist on brushing your child's teeth, be sure to buy a very soft toothbrush. Jiang Nan looked at the hard-bristled toothbrush in the little girl's mother's hand and frowned.

Most of the toothbrushes at this time were like this, and there were some nano soft-bristled toothbrushes and silicone toothbrushes for babies in later generations, which could not be used at all.

Once the sores in your child's mouth are broken and cause bleeding, it is even worse and difficult to stop.

"What then?" The child's mother asked in a panic, seeing Jiang Nan and them wearing white coats, she naturally thought they were doctors.

"Usually just rinse your child's mouth, but if you really want to brush your teeth, you can gently wipe it with a soft cotton cloth that has been disinfected." Jiang Nan said, walked in front of the child, lowered his body, gently wiped the child's tears, and raised a smile, "Little friend, open your mouth and let your sister see, my sister will prescribe medicine for you, and it won't hurt if you apply the medicine." ”

"Really?" The little girl seemed a little disbelieving with tears in her eyes.

"Really, my sister never lies, come, 'Ah-', open your mouth!"

The little girl opened her mouth, Jiang Nan looked carefully at the girl's mouth, and sure enough, it had broken several places, no wonder it hurt.

"Teacher Xu, the little girl has a serious ulcer in her mouth, and I will go to the Chinese medicine pharmacy to prescribe some ice boron powder for her later, which will be good for her ulcers." Jiang Nan said to Xu Yan behind him.

Xu Yan nodded, and was surprised to see how familiar Jiang Nan was with leukemia, as if she had often treated it before.

Cheng Jing snorted on the side, and she loved to be in the limelight.
