After getting the tissue, Yang Xi slipped out of the big office holding his stomach, and then ......

Go straight to the doctor's duty room.

Alas, it is not easy to be a teacher, there are so many knowledge points, and if you can't answer one of them, you will be embarrassed in front of the students. As a last resort, I had to pretend that my stomach hurt, sneak out to buy myself some time, and quickly find out what kind of triple negative breast cancer is.

Du Niang's search is a learning method, but Yang Xi estimated that Jiang Yubei may have searched for relevant knowledge, if she buys and sells it now, if she is pierced by the heartless Jiang Yubei, she will lose face even more.

Fortunately, I still have a little madman.

What's even luckier is that little madman has given himself a task this week to study oncology?

Drilling into the duty room, Yang Xi hurriedly summoned the system interface, spent 9.9 yuan in the system mall to buy the e-book of "Practical Medical Oncology", and after some searching, he began to seriously learn the relevant knowledge of triple negative breast cancer.

After only watching it for a minute, I fell dizzy.

It's so profound.

It's so hard to understand.

How can it be as good as "Huang Jiasi Surgery", the structure of each map is clear, the level is clear, and the step-by-step operation is concise, bright and vivid.

It is not as easy to learn as "Radiotherapy", which uses X-rays or γ rays, which cannot be seen or touched, but can be imagined.

But this medical oncology ......

ER, refers to estrogen receptors, PR, refers to progesterone receptors, HER, etc., why is there a -2 after it?

HER-2 is a human epidermal growth factor receptor, but what about HER-1, what about HER-3, and is there -4 or -5?

My head is dizzy, and my eyelids are so heavy......

The mobile phone rang suddenly, Yang Xi woke up suddenly, and subconsciously opened the call button.

"Teacher Yang, what are you doing, even the teacher has to call 119 for help. ”

"I'm ......" Yang Xi looked at the time, it was about nine fifty when he came down from the 18th floor, and now, it was half past ten, that is, he squatted in the so-called bathroom for half an hour. "Teacher Yang had severe diarrhea, so I went to the front clinic to get some medicine, and I came back. ”

The e-book was still floating in mid-air, and Yang Xi had no intention of reading it any more. Maybe it's because he used a super memory card, Yang Xi, who originally had a pretty good memory, now has a great memory, although he has a half-understanding of the knowledge points in the book, but Yang Xi believes that Jiang Yubei is still quite sure.

After washing his face at the nurse's station halfway, Yang Xi returned to the doctor's office.

Lian Xiangdong praised sincerely: "Xishao, it's awesome, my brother thought that his ten minutes was enough to be awesome, but I didn't expect that your old man would squat for an hour and a half." ”

Yang Xi said seriously: "What words, didn't I say it, I went to the front clinic to buy medicine." While speaking, Yang Xi threw a look, Ma De, dare to talk nonsense, beware of the young master who wants you to look good.

Lian Xiangdong understood in time and quickly shut up.

More than half an hour has passed, Ye Qiuhe's mental state has returned to normal, and Jiang Yubei's expression has a little smile.

"Where did you just go? By the way, you said that Qiuhe has triple-negative breast cancer, and asked Mr. Yang what triple-negative breast cancer is, right?" Yang Xi pulled a chair and sat opposite the two girls.

Jiang Yubei's expression dimmed in a second, and said: "I just checked, and it was said on the Internet that triple-negative breast cancer refers to estrogen receptors, progesterone receptors, and human epidermal growth factor receptors that are all negative, making the clinical effect of endocrine therapy and anti-HER-2 targeted therapy negligible, and the risk of recurrence and metastasis within 5 years exceeds 20%. ”

Yang Xi said in surprise: "Yes, classmate Xiao Jiang, you can grasp the key point, well, it's not easy." ”

Jiang Yubei said: "In this way, Mr. Yang agrees with the statement on the Internet. ”

Yang Xi nodded, and said: "The medical knowledge found on the Internet is also passed on after some doctors have sorted it out, of course, this does not exclude some information for the purpose of advertising, although it is mixed, for a patient who has no medical foundation, it cannot be advocated that he check these medical knowledge on the Internet, but for a medical student like you who has a considerable medical knowledge base, it is acceptable to take a look occasionally." ”

Jiang Yubei said: "Teacher Yang, are you saying that you are off topic? Now the focus is on Sister Qiuhe's condition, now she can't use endocrine therapy, and the targeted drugs are not effective, what should I do next." ”

"So, I don't advocate that you look up medical knowledge on the Internet, look, even you, a medical student, have been bypassed. Yang Xi lit a cigarette and continued: "What, let Teacher Lian explain this to you next...... Hey, old man, why the are you going?"

Lian Xiangdong had already evacuated several steps, holding his stomach and responding: "Wo Lean, my stomach suddenly hurts badly." ”

At this moment, Lian Xiangdong must have a stomachache, although he is a master's student, and he has studied for three more years than a medical undergraduate, but the major is not right, and he can't say one, two, three.

If you don't slip away, will you be embarrassed?

"Okay, then Mr. Yang will work hard and give you some popular science explanations. Yang Xi cleared his throat, pondered a little, and began to analyze and explain: "It is indeed regrettable that endocrine therapy is ineffective, and a large number of clinical research data show that endocrine therapy plus chemotherapy after breast cancer surgery can greatly reduce the chance of recurrence and metastasis within 5 years. However, to draw such a conclusion, it is summarized from a large sample of data, and for individual cases, it is necessary to analyze specific problems, do you understand this truth?"

Jiang Yubei nodded, and Ye Qiuhe also focused his attention on Yang Xi.

"Qiuhe's pathological diagnosis is moderately differentiated ductal carcinoma in situ, and only the two lymph nodes of the most recent layer of the three layers of lymph nodes dissected during the operation have metastasized, which can basically be divided into middle and early stage patients in terms of clinical stage. In such patients, even if comprehensive treatment is not given after surgery, the possibility of recurrence and metastasis within 5 years is not high. Director Ma said that women comrades have to touch themselves often like Qiuhe, find out early, and solve it early...... Hey, Xiao Jiang, we're discussing medical knowledge, what are you blushing?"

Jiang Yubei glanced at Yang Xi fiercely, and then burst into her signature heartless laughter.

After listening to Yang Xi's explanation, Ye Qiuhe was a lot more relieved, of course, she wasn't too nervous when she first got the results of Sanyin's examination, but she was more calm at this time. "So, I don't have to come back for chemotherapy?"

Yang Xi panicked, hurriedly objected, and said: "That's not good! Endocrine is ineffective, and if I don't do chemotherapy, if there is something long, not bad, wouldn't it ruin my reputation as Dr. Yang?"
