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

   is really a super cute boy.

   When this person started to express academic opinions before, Zhao Zhaowei and the others could already feel: this person's unwillingness to answer is definitely not a humble and low-key behavior.

Zhao Zhaowei frowned, pulled up the corner of Zhang Desheng's shirt and said, "You say it, or Shihua will say it first. This man must have heard something from somewhere. Look at Ying Ying's eyes all the time. Ying look."

   will never be deceived by the super cute appearance of this classmate Ruo Xiaopen. Zhao Zhaowei swears that the members of the National Association are not only Xie classmates, but all of them are ghosts from Teacher Ren's mouth.

   Duan Sanbao heard the words of the boys of the National Association, lowered his head, tapped his pen on the paper and continued to give birth to an ostrich that day.

   Having had a contest with Song Xuelin, the genius in Beidu, Zhao Zhaowei became more and more convinced that his intuition was right: this guy was pretending, ready to take the words of his classmates.

   "Are you participating?" Cheng Yuchen turned his head and asked the students of the National Association.

  The people in the capital jeered and said, "You said, let's discuss together. Don't hide it, it will suffocate people to death."

  With what Zhao Zhaowei said, Zhang Desheng stood up first and said loudly: "I will say one."

  The scene is quiet.

   The hearts of the people from the National Association were beating, and the eyes of the people from the opposite country 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 from not being nervous. After pulling a few times, his throat became lower and said: "On the film, you can see that the angle of the heart is dull, it may be a lung infection, swollen lymph nodes, or something like What he's saying is probably a heart problem. It's unlikely that it's the fat pad, because the patient is not fat at a young age."

The    human diaphragm appears as an arch like an arch on the frontal and lateral chest radiographs. The projection of this arch and the heart will form an angle, called the septal angle, which is actually the angle between the inside of the lung and the heart. If the human body is dissected, because the human body is a three-dimensional space, the definition of this heart septal angle is more complicated. There is a pericardium on the outside of the heart, the lungs on both sides, and the chest wall before and after. The septal angle is the three-dimensional angle between the pericardium and the lung or chest wall.

   It is impossible for a doctor to see 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 experience.

  The medical experience is: In normal people, the heart septal angle shown on the chest X-ray is sharp. If it becomes dull, it may be due to the exudation of nearby inflammatory tissue causing the shadow to become larger, and it is possible that the lungs are infected with swollen lymph nodes. Another possibility is that the heart becomes larger and the projection of the heart becomes larger, and the included angle naturally becomes blunt. In the case of obese people, there is a possibility of misdiagnosis of heart disease due to the large amount of fat.

   Zhang Desheng answered the outline of another doctor's reading of the patient's chest X-ray.

   When the doctor looks at the examination report, it is not only to see if the direction of his suspicion is correct, but all other aspects need to be clearly seen, so as to determine whether the patient has other physical problems.

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