Chapter 2303 【2303】Cover Yingying

"Teacher, you can ask the students from the school next door to participate in the discussion. It doesn't have to be me alone." Duan Sanbao replied.

His voice is like glutinous rice, glutinous and waxy, with a slow tone, accompanied by bright eyes with a bit of sweetness, like a kindergarten child who is serious about studying.

Really cute boy.

When this person started to express his academic opinions, Zhao Zhaowei and the others could feel that this person's reluctance to answer was definitely not an act of modesty and low-key behavior.

Zhao Zhaowei frowned, pulled up the corner of Zhang Desheng's clothes and said, "Say it, or Shihua first. This man must have heard something from somewhere. Look, his eyes have been staring at Ying. Ying see."

You will never be fooled by the super cute appearance of this classmate Ruo Xiaopenyou. Zhao Zhaowei swears that the members of the Guoxie team are not only Xie classmates, but all of them are the ghosts that Teacher Ren said.

Duan Sanbao heard what the boys from the National Association of China said, lowered his head, tapped his pen on the paper and continued to give birth to ostriches.

Having had a contest with the genius Song Xuelin from the Northern Capital, Zhao Zhaowei became more and more convinced that his instinct was right: this guy was pretending to thank his classmates.

"Are you participating?" Cheng Yuchen turned to ask the students of the National Association.

People from the capital booed: "Say it, come in and discuss together. Don't hide it, it will suffocate people."

With Zhao Zhaowei's statement, Zhang Desheng stood up first, and said loudly: "Let me say one."

The scene was quiet.

The hearts of the Guoxie people were beating, and the eyes of the Guodu people on the opposite side seemed to be waiting for them to roll over.

Zhang Desheng, come on. —— Zhao Zhaowei and the others shouted in their hearts.

After receiving the voices from his classmates, Zhang Desheng became tense from not being nervous. He pulled his throat a few times and then lowered his voice, saying: "On the film, you can see that the angle of the septum of the heart is blunted. It may be a lung infection, enlarged lymph nodes, or something like this. What he said may have a heart problem. It is unlikely to say that it is a fat pad, because this patient is young and not obese."

The human diaphragm shows an arch like an arch bridge on the positive and lateral chest radiographs. This arch and the projection of the heart will form an angle, called the intercardiac angle, which is actually the angle between the inside of the lung and the heart. If the human body is dissected, since the human body is a three-dimensional space, the definition of the intercardiac angle is more complicated. There is pericardium on the outside of the heart, lungs on both sides, and chest wall on the front and back. The septal angle is the three-dimensional angle between the pericardium and the lungs or chest wall.

It is impossible for a doctor to say that he saw the three-dimensional space of the human body when looking at the chest X-ray. He can only make a rough judgment and sum up a set of experiences.

The medical experience is: for normal people, the septal angle shown on the chest radiograph is sharp. If it becomes blunt, it may be that the nearby inflammatory tissue exudates and causes the shadow to become larger, and lung infection and lymph node enlargement are all possible. Another possibility is that the bigger the heart is, the bigger the projection of the heart becomes, and the included angle naturally becomes blunt. If you are obese, you may be misdiagnosed as heart disease due to excess fat.

Zhang Desheng answered another doctor's summary of reading a patient's chest X-ray.

The doctor reads the examination report not only to see whether the direction of his suspicion is correct, but also to see all other aspects clearly, so as to determine whether the patient has other physical problems.

To read the most common frontal and lateral chest radiographs, it is necessary to distinguish lungs, heart, mediastinum, pleura, diaphragm, ribs and other organs.
