Chapitre 2943: Dog-licking

"General manager Zhou, the patient is here for Rheumatology immunity." Zheng Ren said.

"Why don't I see the cricoid cartilage ... It seems to have dissolved?" Zhou Litao asked in surprise.

"As a rare disease, the cause and mechanism of relapsing polychysanthema are still unknown. It is reported to be an autologous-immune disease, but it also has a certain hereditary tendency. The specific mechanism of the disease is still under further research."

Zheng Ren explained,"the symptoms of this disease in the lungs are mainly seen when the disease is accompanied by tracheal cartilage inflammation. Pathological examination shows that the tracheal cartilage has dissolved, the trachea mucous membrane is swollen, and granulation, etc. The windpipe cavity can become narrow and even blocked."

"But ..." Zhou Litao paused for a moment. He still had some doubts, but how could he voice his doubts about boss Zheng's words? he swallowed them back.
