Patient: Onset in ’99, diagnosed in ’05. Can I use Yunnan Baiyao for intestinal bleeding? Patient: Hello, Director Ren: I am a CD patient. But from Dr. Ren’s confidence and treatment, every CD patient’s improvement brings great joy. You have a lot of work to do every day, and you are always available to answer questions from patients. I wish you more success in your work and look forward to your success in overcoming CD. General Surgery Department of Nanjing Military Hospital, Ren Jian’an: You can take Yunnan Baiyao orally. One is easy to bleed, that is, there is a broken wound, the approach is to try to control the onset of Crohn’s disease . The second is that it is not easy to stop the bleeding. Since most patients with Crohn’s disease have lesions concentrated in the terminal ileum, which is the main site of vitamin K absorption. Vitamin K is an essential substrate for the synthesis of several important clotting factors by the liver, and the clotting mechanism of Crohn’s disease patients is very poor. It is not easy to stop the bleeding. This is a problem that some general practitioners tend to overlook. After all, Crohn’s disease has been increasing in China in the last decade. So you can check one of your coagulation indicators. Prothrombin time (PT), if it exceeds the normal value, you can subcutaneous injection of a little vitamin K1, many miraculous results. Thank you for your encouragement! Patient: I am very grateful to Director Ren for answering my questions seriously in his busy schedule, and I wish him all the best! Please also treat yourself well and rest early. General Surgery Department of Nanjing Military Hospital, Ren Jianan: Yes, thank you for your concern! Patient: Hello, Director Ren: My intestinal bleeding situation is under control, and it was a recurrence of CD that I controlled with the least amount of money. Vitamin K1 cost 50 cents and it really worked wonders! As you said to a consultant it is best not to bother you, that is your good wishes for the patient. I can also face my disease, although I have been following your personal website for six or seven months, and have not met with you, but I feel that your guidance online is very timely and accurate, you do not have much time off every day, and I do not really want to delay your time, this time the intestinal bleeding situation is more serious so I can only trouble you. Thank you very much for your excellent medical skills and noble medical ethics. Happy birthday to the director! I wish you all the best in your work! Happy family! General surgery Ren Jian’an: through the online diagnosis, as when the eunuch doctors to the Empress Dowager’s “hanging red line diagnosis”, do not see people, all based on the complaint, a little mysterious. This time it worked, all based on experience and luck. But the Internet does provide us with a more convenient way to solve problems. Keep in touch.
