"Teacher, you can let students from the school next door participate in the discussion. I don't always have to speak alone." Duan Sanbao replied.
If you listen carefully, his voice is a bit like glutinous rice, glutinous, slow in tone, and a little sweet with bright eyes, like a kindergarten child who is studying seriously.
What a really cute boy.
When this person began to express his academic opinions before, Zhao Zhaowei and the others could already feel that this person's unwillingness to answer was definitely not a humble and low-key behavior.
Zhao Zhaowei frowned, pulled up the corner of Zhang Desheng's clothes and said, "You say it, or Shihua says it first. This guy must have heard something from somewhere. Look at his eyes that have been staring at Ying. Yingkan."
You will never be fooled by the super cute appearance of this classmate Ruo's little friend. Zhao Zhaowei swore that the members of the National Association were not only classmate Xie, but all of them were what Teacher Ren called elves.
When Duan Sanbao heard the words of the boys from the National Association, he lowered his head and tapped the pen on the paper to continue giving birth to ostriches that day.
Having competed with Song Xuelin, the genius from Beidu, Zhao Zhaowei became more and more convinced that his intuition was right: this guy was pretending and was trying to trick his classmate into thanking him.
"Are you participating?" Cheng Yuchen turned to ask the students of the National Association.
The people in the capital shouted: "You guys said, come in and discuss it together. Don't hide it, it will suffocate people to death."
After classmate Zhao Zhaowei's statement, Zhang Desheng stood up first and said loudly: "Let me tell you something."
The place was quiet.
The hearts of the people in the National Association were beating, and the eyes of the people in the capital opposite seemed to be waiting for them to overturn.
Zhang Desheng, come on. ——Zhao Zhaowei and the others shouted in their hearts.
After receiving the voice of his classmates, Zhang Desheng became nervous. He raised his voice a few times and then lowered his voice and said: "You can see on the film that the septal angle has become blunt. It may be a lung infection, swollen lymph nodes, or something like this." What he said was that there might be a heart problem. It is unlikely that it was a fat pad because the patient was young and not obese."
The human diaphragm appears as an arch like an arch bridge on the front and side views of the chest X-ray. This arch and the projection of the heart will form an angle, called the septal angle, which is actually the angle between the inner side of the lungs 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 the pericardium on the outside of the heart, the lungs on both sides, and the chest wall on the front and back. The septocardial angle is the three-dimensional angle between the pericardium and the lungs or chest wall.
Doctors cannot say they see the human body in three-dimensional space when looking at a chest X-ray. They can only make a rough judgment and summarize a set of experience.
Medical experience is that for normal people, the septocardial angle shown on the chest X-ray is sharp. If it becomes dull, it may be caused by the leakage of nearby inflammatory tissue, causing the shadow to become larger, or the lung infection may lead to swollen lymph nodes. Another possibility is that as the heart becomes larger, the projection of the heart becomes larger, and the angle naturally becomes blunter. For obese people, there is a greater possibility of being misdiagnosed as heart disease because of their excess fat.
Zhang Desheng finally answered another doctor’s summary of reading a patient’s chest X-ray.
When the doctor looks at the examination report, he not only needs to check whether the direction of his suspicion is correct, but also needs to look at all other aspects clearly to determine whether the patient has other physical problems.
To read the most common anteroposterior and lateral chest radiographs, it is necessary to distinguish the lungs, heart, mediastinum, pleura, diaphragm, ribs and other organs.
