Rheumatoid arthritis is a chronic disease characterized by non-suppurative inflammation of joints and peri-articular tissues, and is a disease of the autoimmune system. The treatment of rheumatoid arthritis is still a worldwide problem, and there is no cure for the disease, which mostly occurs in small joints, such as the hands, feet and wrists, and may have temporary remission. According to statistics, rheumatoid arthritis has a relatively high mortality rate, showing that the condition itself does not cause the death of patients, but rather some inflammatory system complications caused by RA, such as cardiovascular disease and lung disease, are the main causes of death. The cause of rheumatoid arthritis is unknown. However, the pathogenesis is related to the following factors: 1, infection: streptococcal cell wall fragment water suspension injected into the rat’s abdominal cavity, can produce chronic arthritis, the feces of patients with this disease can be cultured a large number of gas-producing bacillus, the patient’s synovial membrane has been found in the virus particles. The above findings indicate that the development of the disease is related to infection. 2, genetic: there is evidence that people with a family history of rheumatoid arthritis have a much higher chance of developing the disease. 3, immune dysfunction: a large number of experimental data prove that rheumatoid arthritis is an inflammatory disease caused by dysfunctional regulation of the immune system. 4, cold: there is evidence that people who live in cold places are more likely to develop the disease than those who live in warm places. The rheumatoid arthritis is thought to be the result of poor living conditions, but data show that more and more young people in urban areas are suffering from rheumatoid arthritis, in addition to the above reasons, mostly related to their poor lifestyle, too much pressure at work or some bad habits, such as taking a cold shower immediately after exercise in the summer may cause people to suffer from rheumatoid arthritis. Rheumatoid arthritis is a very complex condition, and for patients, a little inattention can aggravate the condition, such as overwork, mood, cold, flu, and infection.
