Purpura nephritis (anaphylatic purpura nephritis) is a kidney damage caused by allergic purpura, which can be caused by allergic reactions caused by bacterial, viral and parasitic infections, or by allergies to certain drugs and foods, or by plant pollen, insect bites and cold stimuli. In addition to skin purpura, joint pain, abdominal pain and blood in stool, the clinical manifestations are mainly hematuria and proteinuria, mostly occurring within one month after skin purpura, some may see skin purpura and abdominal pain at the same time, while some only have asymptomatic urinary abnormalities. If protein loss is excessive, nephrotic syndrome may appear. If hematuria and proteinuria persist for a long time, it may be accompanied by renal decompensation and finally lead to chronic renal failure. The proportion of allergic purpura leading to renal involvement is 20% to 100%, with more male patients than female. Therefore, Professor Gao Jining focuses on the use of heat-clearing and detoxification methods in the treatment process, and according to the different causes of heat toxicity, he uses the corresponding heat-clearing and detoxification drugs, reflecting the principle of Chinese medicine. 2.Taking into account the deficiency and the reality Although the disease is mainly evil in the early stage and positive deficiency in the later stage, it is often mixed with deficiency and reality, so Professor Gao Jining pays special attention to taking into account the deficiency and reality when treating the disease. For those who are predominantly evil, the evil is easily depleted of qi and yin, so in the process of medication, the actual evil is eliminated and supplemented with benefits for qi and yin; while for those who are predominantly deficient, there are often signs of actual evil such as stasis, dampness, heat and toxicity, etc. To help the positive do not forget to eliminate the evil, so as to help the positive not to help the evil, and to eliminate the evil not to hurt the positive, and to balance the symptoms and the root. 3, invigorate blood circulation and resolve blood stasis “Blood evidence theory” cloud: “everything has a root, when the time will be hair, blood loss what root, blood stasis is also its root, so repeatedly hair, the period of more volatile blood stasis.” According to this theory, Prof. Gao Jining concluded that patients with allergic purpura nephritis are manifested as rash spots on the outside, and blood oozing on the inside will also become stasis for a long time. “The actual blood stasis goes away, the new blood is born, the hundred veins are open, the blood returns to the meridian, the purpura is removed”, more in the selection of prescriptions with blood circulation drugs, the original idea. Diet and regulation 1. With the gradual understanding of this disease, it is gradually realized that diet is significant to this disease in terms of prevention and recovery. To this end, the following recommendations are made to friends with kidney disease: avoid contact with allergens, avoid eating seafood and other hairy products and allergy-prone drugs; advocate a light diet, nutritious diet, avoid spicy, greasy, fatty, sweet and thick; patients should eat more products that strengthen the spleen and stomach, such as yams, malt, etc., after the condition is stable, the intake of animal protein in moderation, and advocate soup dietary therapy; before the allergens are clear, avoid eating foods that have never been tried before. Avoid eating foods that have never been tried before until the allergen is clear, to reduce the recurrence of the disease. 2, in life, patients with the disease should choose loose cotton clothes, to prevent the evil out of the poor and depressed skin, pay attention to rest, appropriate exercise to strengthen their immunity.
