Chronic colitis is a common clinical condition whose development is associated with a variety of factors. It is a chronic non-specific inflammation of the mucosal layer of the colon and rectum. Clinical manifestations of diarrhea, abdominal pain, abdominal distension or urgency, stools with mucus or pus and blood, often accompanied by fatigue, poor performance, unclean bowel movements, anal swelling, mood irritability and other symptoms. It brings a lot of inconvenience to the normal work and life of patients. Modern medicine for this disease is not yet a special treatment drugs. The Chinese medicine believes that chronic colitis belongs to the Chinese medicine “diarrhea”, “intestinal nettle thin I Ψ thin bar喽 exhausted thin trek aluminum barium category. The location of the disease in the intestines, the internal organs in the liver, spleen, stomach and kidney. I, the etiology of the disease in the same external environmental conditions, affected by the same pathogenic factors, some people develop, some do not develop. The reason: “Jing Yue Quan Shu”: “The origin of diarrhea and drainage is always from the spleen and stomach”. The spleen is responsible for transportation and transformation, and is the “source of biochemistry of qi and blood” and the “foundation of the latter day”. Due to congenital or due to poor diet, fatigue, and long days leading to damage to the spleen and stomach, the spleen does not have healthy transportation, the qi and blood are not enough to moisten the whole body, phlegm and drinks are generated internally, or the damp evil turns into heat and cold over time; stopping in the intestines, the large intestine does not conduct properly, and the qi and blood and the dregs in the intestines are knotted together, damaging the intestinal complex. Long-term diarrhea does not heal, and the kidneys are affected over time, resulting in spleen and kidney Yang deficiency. In addition, emotional injury, liver loss of drainage, liver qi transverse to offend the spleen and earth, liver and spleen disharmony, liver depression and spleen deficiency, resulting in spleen and stomach damage. In conclusion, the disease is a mixture of deficiency and reality, with the original deficiency and the symptoms being real. Weakness of the spleen and stomach is the main cause; damp-heat, phlegm-dampness and blood stasis are the symptoms. On the other hand, the deficiency of positive energy is easily injured by external sensation, diet and emotion, which makes it difficult to heal and recurrent. Any disease is a process of change and development, and each stage has a key link. To address the characteristics of the disease, the combination of evidence and disease identification, “urgent is to treat its symptoms, slow is to treat the root”, support and eliminate evil. 1.Acute attack period. Symptoms: diarrhea, abdominal pain, abdominal distension, mucus-purulent-blood stools more than 10 times a day, shortness of breath, fatigue, poor appetite and emaciation, red tongue, yellow and thick greasy coating, pulse count. Routine stool examination: a large number of red and white blood cells (e.g., 20-30 red blood cells, full field of white blood cells). Most of the cases at this stage are due to the evil of dampness and heat, stagnation in the intestine, and the blood and qi, blood defeat and flesh decay. Treatment is to clear heat and dampness, cool the blood and stop bleeding. 2. Chronic phase. This phase is relative to the acute attack phase, there may still be mucus-purulent-blood stool, but the stool routine + occult blood shows: 0-8 red blood cells, 1-5 white blood cells, a significant reduction compared to the previous. The main focus is to help the righteousness, according to the different types of evidence, the diagnosis and treatment are as follows: 2.1 spleen deficiency damp-heat type: symptoms: diarrhea abdominal 0, yellow thick greasy coating, pulse string. Treatment is to clear heat and dampness, benefit Qi and strengthen the spleen. 2.2 Spleen qi weakness type: symptoms: abdominal pain, loose stools, several times a day with mucus or indigestible diet, symptoms aggravated after eating cold, greasy food, withered face, light red tongue, thin white moss, weak pulse. Treatment is to benefit the qi, strengthen the spleen, and relieve dampness. 2.3 Spleen and kidney yang deficiency type: i.e. generalized cold symptoms, diarrhea and abdominal pain when cold is encountered. Spleen and Stomach Theory? The Spleen and Stomach: “The source of the deficiency of the spleen and stomach is the deficiency of yang energy and the surplus of yin energy.” 2.4 Liver and spleen disharmony: Symptoms: abdominal pain, bloating, diarrhea or constipation, stool once a day or several times a day with mucus, pain decreases after stool, especially aggravated by emotional disorders, light red tongue, thin white moss, pulse is hypochondriac. Treatment is to dredge the liver and strengthen the spleen. 2.5 Retention enema treatment method This method is a combination of local and overall treatment. The drug reaches the disease directly and takes effect, avoiding the influence of the digestive tract on it, maintaining the performance of the drug, quickly and fully exerting the therapeutic effect, and its efficacy is sure. The use of dialectical medicine: Huang Lian, Lian Qiao, Licorice, etc., together with oral Chinese medicine to play a half-hearted effect. For patients with positive fecal occult blood, 3g of Panax ginseng powder or 2g of Qing Dai can be added to the decocted enema to activate blood circulation and stop bleeding, and clear heat; if the local ulcer is heavy, 1g of tin-like dispersion (watermelon cream, borax, Qing Dai, ice chips, pearl, niuhuang, etc.) can be added to detoxify and relieve swelling, produce muscle and relieve pain. Fifteen days is a course of treatment, after which it is discontinued for one week, followed by the next course of treatment. However, this disease originates from the weakness of the spleen and stomach, and is prone to recurrence, so prevention is important. We should pay attention to keeping warm, moderate diet, and strengthen exercise. In addition, the increasing pressure of work life in today’s society is one of the important reasons why the incidence of the disease is on the rise, so it is important to maintain a good state of mind and a relaxed mood.
