目的 研究用低强度激光辐射(НИЛИ)矫治类风湿关节炎(PA)患者免疫失衡的可行性。 资料与方法 共观察了128例PA患者。入选条件为:①符合4项或更多PA诊断的诊断指标;②18岁以后才发病,现年小于65岁;③病程未超过15年。所有患者此前均曾进行过药物治疗。患者被分为2组,其性别、年龄、病程、临床X-线特征及所进行的药物治疗均相似。第1组65人仅继续进行PA的药物治疗。第2组63人,除药物外还加用НИЛИ(辐射位于红外区、λ=0.89μm.脉冲功率5W,脉冲串频率150～3000Hz),在皮肤上照射罹患关节局部及肾上腺(T_(12)～L_2)、胸腺(胸骨平第2肋处)和血管 Objective To investigate the feasibility of using low-intensity laser radiation to treat patients with rheumatoid arthritis (PA). Materials and Methods A total of 128 PA patients were observed. Selection criteria: ① meet 4 or more diagnostic criteria for diagnosis of PA; ② onset after 18 years old, now less than 65 years of age; ③ duration of not more than 15 years. All patients had previously had medical treatment. Patients were divided into two groups with similar sex, age, course of disease, clinical X-ray findings, and drug therapy. Group 1 65 people only continue the PA drug treatment. In group 2, there were 63 patients who were exposed to the skin with T_ (12) and T_ (12) T_ (12) ~ L_2), thymus (sternal second ribs) and blood vessels
