Rheumatoid arthritis is claimed rheumatoid (RA) again, is the not clear as yet chronic systemic inflammatory property disease of a kind of cause of disease, is main clinical manifestation with pathological changes outside chronic, symmetry, many synovial jointss inflammation and the joint, belongs to the autoimmune inflammatory diseases.This disease is sent out well in little joints such as hands, wrist, foots, and outbreak is symmetrical distribution repeatedly.Joint red and swollen heat pain and dysfunction are arranged in early days, and late period, stiff deformity in various degree can appear in the joint, and with bone and skeletal muscle atrophy, very easily disabled.From the angle of pathological change, rheumatoid arthritis is a kind of synovium of joint (can feed through to articular cartilage, osseous tissue, articular ligament and flesh key later on) that mainly involves, and is the popularity diseases associated with inflammation of connective tissues such as serous coat, the heart, lung and eye secondly.The general performance of rheumatoid arthritis also has heating, fatigue and weak, pericarditis, subcutaneous nodule, pleuritis, arteritis, peripheral neuropathy etc. except that arthropathy.Generalized rheumatoid arthritis also comprises the popularity pathological changes of whole body except that the inflammatory disorders of joint part.
Traumatic arthritis is many because of wound or lasting chronic strain cause articular cartilage generation degeneration or form bony spur, shows as that diseased joints is swollen, pain and the dyskinesia, is prone to occur in prudent joint, like joints such as shoulder, knee joint, ankles, sees among athlete and the person between twenty and fifty more.
Osteoarthritis is a kind of modal arthropathy, and the title of osteoarthritis is extremely many, like HOA, degenerative osteoarthritis, degeneration property arthritis, hyperplastic osteoarthritis or osteoarthritis, all refers to a kind of disease, the domestic unified osteoarthritis of using.Its prevalence increased along with the age, and the women is more multiple than the male.Osteoarthritis is with the far-end and the PIP of hands, and knee joint, elbow and shoulder joint and joint of vertebral column are got involved easily, the then less morbidity of wrist, ankle joint.Osteoarthritis is caused by tissue degeneratiaon and the strain of accumulation property; Be more common in fat overweight middle-aged and elderly people; The position of regular incidence is that knee joint, finger, neck, lumbar vertebra etc. are located; Symptom is mainly arthralgia, stiff (meeting feel pain relief behind light activity), and arthroncus, amyotrophy etc. can appear in weight person.
Suppurative arthritis is often invaded articular cavity by antibacterial and is caused, is more common in children, often betides hip joint, cardinal symptom be the part red, swollen, bitterly, heat and dysfunction, and whole body poisoning symptom such as hyperpyrexia.
The arthritis no matter which kind of reason causes or the arthritis of which kind of type, diagnosis and treatment early are in order to avoid cause permanent joint function disturbance even disable.
Being used to treat all kinds of arthritis has multiple medicine, and Western medicine has penicillamine, salicylic acid preparation, indometacin, propionate biology, immunosuppressant, levamisole etc.But the side effect of Western medicine is paid close attention to and is estimated by the world day by day, and the sense of self-protection of disease of patient treatment simultaneously makes many pharmacy corporations strengthen the natural drug of dynamics of investment and speed research and development effective and safe in continuous enhancing.
