Rheumatoid arthritis (RA) is an autoimmune disease with mainly symmetric polyarticular lesions, with clinical manifestations of joint pain, morning stiffness, swelling, and functional limitation as the main manifestations. A. Diagnostic criteria for rheumatoid arthritis Necessary conditions include: 1. ≥ 1 joint swelling and pain, and clinical, ultrasound or MRI evidence of synovitis; 2. If undifferentiated arthritis, exclude signs and symptoms of arthritis caused by other diseases. The diagnosis of RA can be confirmed if the 2 necessary conditions are met and there are radiological changes of bone destruction typical of RA. If the necessary conditions cannot be met, the following scoring system is entered. The scoring system is divided into 4 parts: 1. Involved joints: Any swollen or tender joint found on physical examination can be confirmed as synovitis by imaging evidence of synovitis (MRI or ultrasound). Involved joints are divided into large joints and small joints, and are recorded as 0-5 points according to the number of joints involved. 2. Serology: rheumatoid factor and anti-cyclic citrullinated fetal antibodies were scored as 0-3 according to their titers. 3.Acute phase reactants: normal or abnormal CPR or ESR were scored as 0-1, respectively. 4. Duration of symptoms: <6 weeks was scored as 1. A score of 6 or more can be classified and diagnosed as rheumatoid arthritis. The treatment and prognosis of rheumatoid arthritis Because there is no special treatment drug for RA, still mainly non-steroidal anti-inflammatory painkillers, drugs to improve the condition, glucocorticoids, biological agents, etc., there are unstable clinical efficacy, long treatment period, drug adverse reactions, high economic costs, coupled with the long duration of RA, joint symptoms are easy to recur, and the prognosis is poor, so it can be said that RA is China's Therefore, it can be said that RA is one of the most widespread and serious chronic diseases in China. At present, the focus of RA treatment is still on improving joint symptoms, preventing joint deformation, restoring joint function, delaying disease progression, and reducing complications. RA is mostly caused by kidney deficiency or liver and kidney deficiency, and the disease is located in the bones and tendons, and the disease is caused by wind, cold, dampness, heat, blood stasis and phlegm, and "different is pain". RA is predominant after the chronic remission period, treatment should be based on tonifying the kidneys and warming the liver, together with the elimination of evil, the liver and kidneys are not deficient, warming the tendons and bones, so that the disease is not deep ambush. In the acute stage, heat toxicity and dampness-heat are the main factors, so we should treat the symptoms urgently, mainly to eliminate heat and dampness and detoxify the toxins, and then tonify the liver and kidneys after the disease is relieved, and remove the remaining evil to consolidate the treatment effect. In chronic remission, acute attackers have symptoms of heat toxicity and damp-heat, and also have deficiency of liver and kidney, so treatment should not be focused on eliminating the evil, so as not to injure the right to prolong the disease, when the liver and kidney and clear heat and dampness detoxification at the same time.
