Objective To observe the results and reality of transurethral resection of bladder tumor(TUR-Bt) with upside down loop and plsamakinetic in the prevention of obturator nerve reflex.Methods A total of 211 patients with lumbar anesthesia received TUR-Bt.Firstly,the tumor tower above bladder wall was cut with the traditional way.When intraoperative findings were obturator nerve reflex,or to the obturator nerve mapping area,operation should be changed to superimpulse plasma column electrode vaporization to cut off residual tumor tissue,then after flipping the loop,the residual tumour was resected with upside-down loop from the tumour side wall.Results In 211 cases,192 cases had a little obturator nerve reflex,but the movement of body was not obvious,which did not influence the operation.The serious complication,such as perforation of bladder and injury of nerve and vessel,did not occur.Conclusions The lateral resection of bladder side wall tumour with upside-down loop can effectively avoid strong obturator nerve reflex,which is safe,uncomplicated,and efficacious and it does not increase the additional outlay and hurt.

Objective:To study the effect of Compound Duzhong Jiangu Granules on joint function, quality of life and inflammatory factors in patients with Kashin-Beck disease.Methods:By group design, 135 patients with Kashin-Beck disease in Chongxin County, Pingliang City, Gansu Province, were selected and divided into intervention group (100 cases treated with Compound Duzhong Jiangu Granules, 12 g/bag, 1 bag/time, 3 times/day, treatment for 1 month) and control group (35 cases treated with ibuprofen, 0.3 g/capsule, 1 capsule/time, 2 times/day, treatment for 2 weeks) according to the randomized, single-blind principle. The changes of joint dysfunction index score, joint function improvement rate, total scores of Kashin-Beck disease quality of life (KBDQOL) and scores of each dimension were analyzed before treatment, 1 month and 3 months after treatment. The serum levels of interleukin-6 (IL-6), nuclear factor κB (NFκB)-p65, inducible nitric oxide synthase (NOS2), nitric oxide (NO), and prostaglandin E2 (PGE2) were detected by enzyme-linked immunosorbent assay before treatment and 1 month after treatment.Results:The total scores of joint dysfunction index of the intervention group and the control group 1 month after treatment and 3 months after treatment were lower than those before treatment, but 3 months after treatment was higher than 1 month after treatment ( P < 0.001). One month after treatment, the total effective rates of joint function improvement in the intervention group and the control group were 68.00% (68/100) and 54.55% (18/33), respectively; 3 months after treatment, the total effective rates of the intervention group and the control group were 36.00% (36/100) and 39.39%(13/33), respectively. The total scores and scores of each dimension of KBDQOL were not significant for the main effect of the group ( P > 0.05), but significant for the main effect at the time point ( P < 0.05), and there was no interactive effect ( P > 0.05). There were significant differences in the scores of social support and mental status dimensions in the intervention group at different time points ( P < 0.001). And in the intervention group, the total score, the scores of physical function, activity limitation, economy and overall health dimensions were statistically significant between before treatment and 1 month after treatment, 1 month after treatment and 3 months after treatment( P < 0.05); however, there was no significant difference between before treatment and 3 months after treatment ( P > 0.05). One month after treatment, the serum PGE2 levels of both groups were decreased ( P < 0.05), and there was no difference in other inflammatory factors at different groups and time points ( P > 0.05). Conclusion:Compound Duzhong Jiangu Granules can effectively inhibit the inflammatory reaction of patients with Kashin-Beck disease, promote the improvement of joint function and improve the quality of life in various aspects.
