目的：分析小兒紫癜性腎炎的臨床特點。方法：回顧分析兩院兒科最近8年收治的小兒紫癜性腎炎180例的臨床表現、實驗室檢查結果，治療和預后等方面的資料。結果(1)臨床以血尿蛋白尿型最多見(61/180)，其次為急性腎炎型(36/180)、腎病綜合征型(31/180)和單純血尿或蛋白尿型(25/180)。(2)重癥病兒短期使用激素可改善腎臟損害。(3)所有病例均有必要長期隨訪。結論：小兒紫癜性腎炎絕大多數預后良好，但病情反復不愈者可發展為終末期腎臟損害，故需要長期隨訪。
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.
