OBJECTIVE:To study and evaluate the efficacy and safety of homemade sterilized powder for injection of rifampicin(weifunin) in the treatment of pulmonary tuberculosis(PT) and to compared with same import preparation . METHODS:Divide the 121 of bacteriological positive PT patients in the proportion of 1 to 1 with computer automatically into the trial group and the control group used with homemade rifampicin (weifuxin) and import rifampicin(nifu)respectively,the others regimens was same in 2 groups,to evaluate the sputum culture negative conversion rates,X-ray results and adverse drug event etc.after treatment 1 and 2 months . RESULTS: 116 cases were finished ,at the end of 2 month the sputum smear negative conversion rates were 86.21 % and 91.38% (X2=0.780,P=0.377), the sputum culture negative conversion rates were 91.38% and 93.10%(X2=0.120,P=0.729)in the trial group and the control group respectively .The X-ray remarkable effective rates of 2 groups were 82.76% amd 70.69%(X2=2.365,P=0.124)respectively, and the effective rates of the 2 groups were both be 96.55% .The adverse drug event rates were 8.20% and 11.67% respectively, there was on sighificant difference in each indexes .CONCLUSIONS:2 preparation were similar in efficacy ,safety and tolerance.

The lower extremity exoskeleton robot is a wearable device designed to help people suffering from a walking disorder to regain the power of the legs and joints to achieve standing and walking functions. Compared with traditional robots that include rigid mechanisms, lower extremity exoskeleton robots with compliant characteristics can store and release energy in passive elastic elements while minimizing the reaction force due to impact, so it can improve the safety of human-robot interaction. This paper reviews the compliant characteristics of lower extremity exoskeleton robots from the aspects of compliant drive and compliant joint, and introduces the augmentation, assistive, rehabilitation lower extremity exoskeleton robots. It also prospect the future development trend of lower extremity exoskeleton robots.
