补肾断续汤结合髓内钉固定治疗预防胫骨中下段骨折不愈合临床研究

目的:观察胫骨中下段骨折应用补肾断续汤联合髓内钉固定治疗的临床疗效。方法:将择期行手术治疗的98例胫骨中下段骨折患者随机分为观察组与对照组,每组49例;对照组行髓内钉固定术治疗,术后予以常规处理;观察组在对照组的基础上于术后第2天开始口服补肾断续汤治疗,所有患者均治疗3个月;观察比较2组临床疗效及骨折愈合时间、骨折不愈合发生率,治疗前后疼痛视觉模拟评分法(VAS)评分、血液流变学指标[全血高切黏度(WBHV)、低切黏度(WBLV)、红细胞聚集指数(EAI)、血浆黏度(PV)]、骨代谢指标[碱性磷酸酶(ALP)、骨钙素(BGP)、钙(Ca)、磷(P)]水平变化。结果:骨折愈合总有效率观察组为95.9%,对照组为81.6%,差异有统计学意义(P <0.05)。治疗后,观察组骨折愈合时间短于对照组、骨折不愈合率低于对照组,差异均有统计学意义(P <0.05)。治疗后,2组疼痛VAS评分均较治疗前显著下降(P <0.05),且观察组VAS评分明显低于对照组(P <0.05)。治疗后,2组各项血流变学指标WBHV、WBLV、EAI、PV值均较治疗前显著降低(P <0.05);且观察组各项指标值均低于对照组(P <0.05)。治疗后,2组患者血清ALP、BGP、P水平均较治疗前显著升高(P <0.05),血清Ca水平显著降低(P <0.05);且观察组上述各项指标改善较对照组更显著(P <0.05)。结论:补肾断续汤联合髓内钉固定治疗胫骨中下段骨折,能明显缩短患者骨折愈合时间,减轻疼痛,有效预防骨折不愈合的发生,其机制可能与改善体内血流变学状态、调控骨代谢有关。

WALK-ASSISTING BALANCE SYSTEM OF THE EXOSKELETON ROBOT FOR DISABLED PEOPLE

A novel methodology for a walk-assisting balance system of the exoskeleton robot for dis-abled people is presented. The experiment on the walk-assisting balance system is implemented using amini-type ropewalker robot. The mechanism of the ropewalker robot is designed, its dynamic model isbuilt, and its control system based on PWM is developed. The emulations in Matlab and the results ofexperiments prove that this methodology is effective.
