Based on the medication treatment, all patients underwent continuous oral administration with Methotrexate（MTX）, Leflunomide（LEF） and Bitongding capsules for 3 weeks. And no other treatments were given to group C. In addition to medications treatment, the electroacupuncture was performed in group B. The acupoints of Tianzhu（天柱 BL 10）,DAzhui（大椎 GV 14）; Fengchi（风池 GB 20）,Quchi（曲池 LI 11）,Quze（曲泽 PC 3）,Chize（尺泽 LU 5）, Shousanli（手三里 LI 10）, Xiaohai（小海 SI 8）, Shaohai（少海 HT 3）, Tianjing（天井 TE 10）,Qinglengyuan（清冷渊 TE 11） and Hegu（合谷 LI 4） in the affected side were selected. A pair of electrodes were connected to LI 11 and LI 10, and another pair of electrodes were connected to PC 3 and LU 5, and the continuous wave with frequency of 2 Hz was designed, the needle retention for 30 min was performed, and the acupuncture was performed for 6 times per week with 3 weeks for one course,and there was one course totally. Besides the medication treatment, group A underwent the acupotomy loosing therapy. The tender point in lateral elbow joint, etc. were taken as the treatment point, and 6-8 treatment points being taken for each time, and longitudinal dredging and transverse exfoliation were conducted for 2-3 times with the acupotomy. The treatment was given for one time per week with three weeks for one course, and there was one course totally. The changes of maximum angle of active extension position, maximum angle of active flexion position and range of motion were observed, and levels of IL-6, IL-10 and TNF-a in affected synovial fluid of elbow joint were tested before the treatment and 2 weeks after the treatment in the groups.Results： ① Compared with those before treatment, the maximum angle of active extension position were smaller, the maximum angle of active flexion position were larger and the range of motion were wider of the affected elbow joints of the patients in the 3 groups on the 2 weeks after the treatment.There were statistical significances for the differences（All P 0.05）. Two weeks after the treatment,as compared with those in group C, the affected elbow joint for patients in the group B and group A was smaller in maximum angle of active extension position, larger in maximum angle of active flexion position and wider in range of motion and there were statistical significances for the differences（All P 0.05）. Comparing with those in the group B, the affected elbow joint for patients in the group A was smaller in maximum angle of active extension position, larger in maximum angle of active flexion position and wider in range of motion and there were the statistical significances for the differences（All P 0.05）. ② Compared with those before treatment, the levels of TNF-a and IL-6 were lower and the level of IL-10 was higher of the 3 groups on the 2 weeks after the treatment. There were the statistical significances for the differences（All P 0.05）. For 2 weeks after the treatment, compared with those in the group C, group B and group A were lower in levels of TNF-α and IL-6 and higher in level of IL-10 and there were the statistical significances for the differences（All P 0.05）. As compared with those in the group B, group A was lower in levels of TNF-a and IL-6 and higher in level of IL-10 and there were the statistical significances for the differences（All P 0.05）.Conclusions： The combination of acupotomy loosing can improve the maximum angle of active extension position, maximum angle of active flexion position and range of motion in affected elbow joint for RA patients with elbow joint stiffness, whose efficacy was superior to single basic treatment and electroacupuncture combined with basic treatment. Meanwhile, the levels of proinflammatory cytokines,such as TNF-α and IL-6 can be decreased, and the level of anti-inflammatory cytokines, such as IL-10 can be increased, playing a role in regulating the imbalance between proinflammatory cytokines and anti-inflammatory cytokines in RA patients, which may be one of mechanisms regarding treating RA and improving the range of motion for stiff joints.展开更多

The retrovirus-mediated delivery of IL-4RA to the airways of mice inhibited elevations of airway responsiveness and the development of allergic inflammation in asthmatic mice, and regulated the Th1/Th2 balance in OVA-sensitized and -challenged mouse models. This suggests that gene therapy is a therapeutic option for treating and controlling chronic airway inflammation and asthma symptoms.展开更多
