The results showed that after intensive training for one week, serum CK levels were significantly increased by 57.53 mmol/L （P〈0.05）. After regulation of the training intensity, average serum CK levels were increased by 21.79 mmol/L （P〈0.05）. BUN contents were increased by 0.83 mmol/L on average with the difference being not significant （P〉0.05）. After intermittent training, there was significant difference in the average increased levels of serum CK in athletes （P〈0.05）. There was significant difference before and after regulation of training （P〈0.05）. The increased levels of BUN were 0.78 mmol/L without significant difference （P〉0.05）. It was concluded that serum CK was one of the biochemical indicators monitoring the training load sensitivity of badminton athletes, but BUN was of little value in monitoring the training load. Both serum CK and BUN recovered slowly after one-week intensive training and intermittent training, suggesting the metabolic mechanism of human body in training needs further study.展开更多

Methods： Thirty two high-risk patients undergoing elective total hip replacement surgery under general anesthesia were chosen from Nanjing Medical University, Affiliated Nanjing First Hospital. In this single-blind randomized controlled clinical triM, patients were randomly assigned to receive preoperative inspiratory muscle training or conventional treatment （CT）. The major effectiveness outcome variables were atelectasis and duration of postoperative hospitalization. Results： Both groups were comparable prior to surgery. Seven patients in the CT group and 3 in the IMT group developed atelectasis （P = 0.25）. Median duration of postoperative hospitalization was 13 days （range, 10～17 days） in the IMT group versus 16 days （range, 11～23 days） in the CT group （Mann- Whitney U statistics, Z = -2.22, P = 0.03）. Mean postoperative inspiratory pressure was 5% higher in the IMT group. Conclusion： Preoperative intensive inspiratory muscle training appears to reduce the incidence of atelectasis and duration of postoperative hospitalization in patients at high risk of developing postoperative pulmonary complications who were scheduled for elective total hip replacement surgery under general anesthesia.展开更多
