Ulcerative colitis (UC) is an immune-related non-specific inflammatory disease of the intestine, the pathogenesis of which is still unclear. In this article, the diagnosis and treatment of the disease are briefly described. The disease can be diagnosed by typical mucopurulent stools with painful diarrhea, continuous superficial ulcers or congested edematous erosions on colonoscopy, and pathology with inflammatory cell infiltration cryptitis and crypt abscesses. Other scholars have proposed that a certain percentage of patients with irritable bowel syndrome later progress to UC, irritable bowel syndrome generally normal colonoscopy and no systemic disease, but long-term regular abdominal discomfort accompanied by abnormal stools, should also pay attention to this phenomenon. But all the diagnosis of UC must first exclude infectious bowel disease, such as acute enteritis, dysentery, etc., and hemorrhoids, this needs to be noted. Treatment, active purulent stool more, mesalazine 4g per day (no significant therapeutic significance of increasing the dose), the symptoms can be controlled then gradually reduced to 2g maintenance; not, add hormone, according to 1mg/kg body weight / day methylprednisolone oral combined with mesalazine treatment, or hormone intravenous or enema treatment, such as effective, hormone gradually reduced to stop; not, immunosuppressive agents or even biological agents or surgery Treatment. In remission, there are few pus and blood stools, or only a small amount of mucus or only abdominal pain, but also constipation type, regular dosage of mesalazine 2g/day, can assist probiotics and other drugs. In Chinese medicine, the disease is resting dysentery, long dysentery, intestinal restaurant, red and white dysentery, etc. The disease is damp-heat containing poison, intestinal complex damage, treatment when clearing heat and detoxifying dampness to stop dysentery, active period clearing heat and detoxifying power, Baitou Weng Tang is the main; relieving period tonifying spleen and benefiting Qi, Ginseng and Atractylodes is the main. Chinese medicine enema is also effective because of its direct action, commonly used to clear heat and detoxify the blood. In our clinical practice, we often use Chinese medicine orally plus enema, and western medicine must be added during the active period, most of which are still effective and can relieve the symptoms and the condition. Most people will ask me how to treat it and what they should pay attention to in general. How to cure the specific analysis, can not be generalized, but must be regular hospital consultation, to build confidence, the disease can not be cured but can be completely long-term relief.
