Yang Chao sat down in front of the microscope and put on his mask again.

Under the microscope is a peeled orange, and next to it are two forceps-like forceps.

"I had a patient, a six-year-old child, who had a disease called craniopharyngioma and had a very high mortality rate."

"The tumor grows in the deepest part of the brain, the saddle area, and the operation is very difficult, and it is easy to recur, and some children die after two or three times."

"Do it two or three times? Isn't that a craniotomy every time? Song Shiwei asked.

"Yes, it's very torturous, and the patient will be miserable." Yang Chao nodded.

"This child's tumor grows around the hypothalamus and pituitary gland, which are the most complex endocrine centers in the body." Yang Chao took out a brain model and explained to Song Shiwei.

"They are mainly divided into a variety of hormones, the most important of which are growth hormone and gonadotropin, and the pituitary stalk plays the role of transporting hormones. They are in control of their children's growth and development. ”

"The tumor grows in this location, and surgery means that these two parts are likely to be damaged, and once damaged, the child may not be able to develop and grow in the future, and will always remain the appearance of a child."

"But if you don't have surgery, it means death, and it's very difficult to operate, so I have to practice more."

Song Shi nodded slightly, "Is it okay to practice with oranges?" Doesn't it look like a brain? ”

"The structure of oranges is quite similar to the brain, you see, there is a gap between the petals of oranges, like a gap between brain tissue. I had to separate the brain tissue to remove the tumor inside, so I used this to practice my hands. Yang Chao said.

"I see!" Song Shi nodded slightly, he gained knowledge, "But it doesn't seem difficult to look at this......"

Usually you don't peel oranges if you are so rude to peel oranges, are oranges different from oranges?

"You're going to try it?" Yang Chao got up, let Song Shiwei sit on the chair, handed her the surgical forceps, and pointed between the two orange petals, "Just separate these two petals." ”

Song Shiwei took the surgical forceps, the tip of the surgical forceps was very thin, only two millimeters, and through the microscope, he could see that the orange petals were magnified many times.

As soon as the two surgical forceps were stretched down, the orange was instantly punctured and juice flowed out.

"Ahh Song Shi exclaimed slightly, is it so fragile?

"I'm sorry!" Song Shiwei hurriedly stood up.

"It's okay." Yang Chao smiled gently, took out a tissue and wiped it clean, "I often did this when I first started practicing, and it took several years of practice to slowly get better." ”

"The arachnoid membrane in the real brain is thinner than this orange membrane, and it looks simple, and our neurosurgeons can't practice it in five years."

Song Shi raised his eyebrows slightly, he really didn't expect that no doctor could succeed casually.

As Xiao Yi said, an excellent surgeon is grinded out little by little.

Yang Chao sat down again, held the surgical forceps in both hands and firmly separated the orange petals, and then took out a surgical thread, which was very thready, and the thread could not be seen at all if he didn't look closely.

"It's the thinnest thread in clinical surgery, several times thinner than a human hair, and it's used to suture blood vessels."

Song Shi stared at it slightly, the line was really too thin, and it was almost invisible to the naked eye.

Zhang Yi came over from the nurse's station and saw that Song Shiwei was still there, and he was with Yang Chao, and the two were so close.

Director Yang usually never lets people around when he exercises, what is the situation today?

Zhang Yi hurriedly called Xiao Yi.

"Xiao Yi, do you know who I saw in our department today?"

"If you have something to say, don't make a fuss."

Zhang Yi sighed, "I saw your wife, she is with our Director Yang, and she is quite ...... Intimate. You have to pay attention, our Director Yang is no worse than you, be careful of being pried into the corner......"

Xiao Yi immediately understood, Weiwei should have confirmed the parent-child relationship and went to Yang Chao to recognize his relatives.

"What nonsense?" Xiao Yi reprimanded, "They are relatives, not what you think." ”

"Ah, Xiao Song and our Director Yang are relatives? How I haven't heard of it. Besides, what kind of relatives are, if it's the kind of distant relatives who can't hit with eight poles, they can't prepare for what people will worry about......"

"No, they are ......" Xiao Yi hesitated for a moment, and did not say that Yang Chao and Song Shiwei were brother and sister, what if Doctor Yang didn't want people to know?

"They are close relatives, very close, closer than cousins. I know, so don't worry about it. ”

"Oh, that's good!" Zhang Yi breathed a sigh of relief, completely unaware of what kind of relatives he was closer than his cousins.

Song Shiwei stood by Yang Chao's side, looking at his preoccupied appearance, he was really handsome.

Thinking of having such an excellent brother, I am very happy.

At this time, the mobile phone in the bag suddenly rang, Song Shiwei said "I'm sorry", took out the mobile phone and went to the side to pick it up.

"Weiwei, you're in the hospital? Zhang Yi said that he saw you. ”

"Well, I'm in my brother's ...... Uh, Dr. Yang here. ”

"Confirmed?"

"Hmm!"

"Doctor Yang, is he okay?"

"It's okay to watch......" Song Shiwei said softly while holding his phone.

Yang Chao turned his head to look at Song Shiwei, thinking that this was his sister, he was still a little excited.

Looking at her delicate face and the way she smiled when she spoke, Yang Chao felt that her heart, which had been empty for so many years, was suddenly filled with something.

Song Shiwei hung up the phone and walked over, and Yang Chao hurriedly looked away.

"Well, I'll leave beforehand, and I'll come back to see you another day. Can I come? ”

"Hmm!" Yang Chao nodded slightly, his expression a little unnatural.

"Bye-bye!" Song Shiwei smiled at him, waved his hand, and left the office.

Yang Chao sat on the chair, unconsciously touching the handle of the surgical forceps with his hand, and a long-lost smile appeared on his face.

Song Shiwei took the elevator to the sixteenth floor.

When she arrived at the doctor's office, Dr. Zhang saw her and shouted, "Director Xiao, your wife is here!" ”

Xiao Yi turned his head, smiled at Song Shi, and stood up, "Come here?" ”

"Hmm!" Song Shiwei sat down beside him.

"I got the paternity test report in the morning." Song Shiwei showed the report to Xiao Yi, and it was Zhou Shuyi who gave her a copy.

"Hello with me at noon...... They went to dinner together, and then I went to see my eldest brother. ”

Xiao Yi raised his eyebrows, "It seems that you can accept your brother?" ”

"Well, maybe it's because I have an older brother, so it's easier to accept the identity of my brother. And he blamed himself for so many years, and I didn't want him to suffer any longer. Song Shiwei said.

"When are you going to tell him?" Xiao Yi asked.

"Why don't you just talk about it now?" Song Shiwei looked at Xiao Yi, "But I'm afraid it's too sudden, will he not be able to accept it?" You'll talk about it for me later. ”

"Okay, I'll call." Xiao Yi nodded.
