BACKGROUND: Nowadays, more and more people regard the isokinetic training as a method for strength training and rehabilitation of muscle injuries of athletes. But it is rare in study of rehabilitation following joint injury via isokinetic training. OBJECTIVE: To explore the advantage of isokinetic training in rehabilitation, further more, to provide the scientific basis to rehabilitation of muscle injuries. DESIGN, TIME AND SETTING: The contrast observation was performed at the Laboratory of Institute of Physical Education, Hebei Normal University between March and May 2008. PARTICIPANTS: Two female college basketball athletes whose knee joints were injured. METHODS: The Kinitech isokinetic testing system (Kylingk, Australia) was used to test the flexion and extension muscles of knee joint of 2 athletes and contrasted the values of flexion and extension muscle after rehabilitation training, damage side and healthy side. All data were analyzed to observe the effects of strength training. MAIN OUTCOME MEASURES: Peak torque (PT) values of flexor and extensor in knee joints. RESULTS: After 8 weeks isokinetic training, the strength index of two subjects had increased in certain degree both at the 60 (?)/s and 240 (?)/s. The PT values showed that the increasing range of flexor was greater than that of extensor in the 1st subject, but the circumstance was opposite in the 2nd subject. The index of BP, STW, and AP was greatly increased, as well as work fatigue. CONCLUSION: It is helpful to increase the muscle strength and promote the rehabilitation via isokinetic training system. The isokinetic strength training has the positive effects on rehabilitation of muscle injuries.

Objective:Based on the detection of CD4+IL17+Th17 and CD4+CD25+Foxp3+Treg cells in the peripheral blood of patients with human papilloma virus (HPV), the study analyzes the ratio of Th17 to Treg and compares the different expression of cytokine IL-17, IL-10, TGF-β, and IL-23 in the serum. Methods:From September 2014 to June 2016, 119 cases of untreated patients with cervical HPV in-fection were collected at the First Affiliated Hospital of Xinjiang Medical University, which include 46 cases of cervical cancer (CC), 43 cases with cervical intraepithelial neoplasia (CIN)Ⅱ-Ⅲ, and 30 with chronic cervicitis (CCS). The detection of HPV types classified 80 patients as high-risk and 39 as low-risk. Flow cytometry examined Treg and Th17 cells, and enzyme-linked immune sorbent assay was used to test related cytokines. Results:In the infection of high-risk cervical HPV, the rate of the CC group was 87%(40/46), which was higher than that of the CINⅡ-Ⅲgroup and the CCS group, which were 77%(33/43) and 23%(7/30), respectively. For the expression of Th17 and Treg cells in the peripheral blood and the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum, the levels of CC group were also significantly higher than that of the other two groups, and the ratio of Th17 to Treg increased considerably with the se-verity of cervical lesions. The expression of Th17 and Treg cells in the peripheral blood of patients with high-risk cervical HPV were higher than that of patients with low-risk cervical HPV (P<0.05), which was the same for the expression of the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum. The ratio of the Th17 to Treg of patients with high-risk cervical HPV increased remarkably (P<0.05). Conclusion:The expression of Treg and Th17 cells in high-risk patients exhibits an increasing trend, and the ratio of increased Th17 to Treg may directly participate in the process of HPV infection and immune evasion, which plays an important role in the occurrence and development of cervical cancer.
