43例轻、中度腕管综合征中西医结合治疗分析

目的：探讨轻、中度腕管综合征中西医结合治疗的临床疗效及安全性。方法：对采用腕管神经阻滞结合中药薰洗及夜间腕关节中立位固定治疗的43例轻、中度腕管综合征患者进行随访观察。43例中单侧患病32例，双侧11例；病程6～24个月，中位数11个月。均表现为桡侧3个半指麻木疼痛，伴夜间麻醒，夜间或晨起时较明显，腕部Tinel征及屈腕试验（Phalen征）阳性。电生理检查均有正中神经掌腕段或腕指段感觉神经传导速度减慢、感觉神经动作电位波幅下降或缺失。根据顾玉东制定的临床分型标准轻度24例，中度19例。结果：治疗过程中未出现药物不良反应，1个疗程治疗后采用上述标准进行评定，本组治愈28例，好转13例，无效2例，总有效率为95．3％。结论：采用腕管神经阻滞结合中药薰洗及支具制动综合治疗轻、中度腕管综合征，更能有效地降低腕管内压力和解除对正中神经压迫，临床疗效满意，值得推广。

Remaining Useful Life Prediction of Li-Po Batteries in UAVs Using Extended Kalman Filter

The use of batteries in UAVs （unmanned aerial vehicles） has become common due to some advantages in comparison with internal combustion engines such as weight reduction and better power control. However, in these vehicles it is critical to monitor the RUL （remaining useful life） of the batteries. This information can be used, for instance, as a decision support tool to define which missions could be assigned to the UAV until the next battery recharge. This work presents a methodology to predict the RUL of Li-Po （Lithium-Polymer） batteries. The approach uses an extended Kalman filter and an exponential model for the degradation evolution. The proposed methodology uses time series of battery terminal voltages, assuming that the discharge occurs under a constant current condition. Different discharge current levels were considered.The results showed that the proposed methodology provides good results, despite its simplicity.
