目的：分析小儿紫癜性肾炎的临床特点。方法：回顾分析两院儿科最近8年收治的小儿紫癜性肾炎180例的临床表现、实验室检查结果，治疗和预后等方面的资料。结果(1)临床以血尿蛋白尿型最多见(61/180)，其次为急性肾炎型(36/180)、肾病综合征型(31/180)和单纯血尿或蛋白尿型(25/180)。(2)重症病儿短期使用激素可改善肾脏损害。(3)所有病例均有必要长期随访。结论：小儿紫癜性肾炎绝大多数预后良好，但病情反复不愈者可发展为终末期肾脏损害，故需要长期随访。
Aiming at the human-computer interaction problem during the movement of the rehabilitation exoskeleton robot, this paper proposes an adaptive human-computer interaction control method based on real-time monitoring of human muscle state. Considering the efficiency of patient health monitoring and rehabilitation training, a new fatigue assessment algorithm was proposed. The method fully combined the human neuromuscular model, and used the relationship between the model parameter changes and the muscle state to achieve the classification of muscle fatigue state on the premise of ensuring the accuracy of the fatigue trend. In order to ensure the safety of human-computer interaction, a variable impedance control algorithm with this algorithm as the supervision link was proposed. On the basis of not adding redundant sensors, the evaluation algorithm was used as the perceptual decision-making link of the control system to monitor the muscle state in real time and carry out the robot control of fault-tolerant mechanism decision-making, so as to achieve the purpose of improving wearing comfort and improving the efficiency of rehabilitation training. Experiments show that the proposed human-computer interaction control method is effective and universal, and has broad application prospects.
