ObjectiveTo observe the effect of kinesio tape (KT) combined with progressive resistance training (PRT) in patients with subacromial impingement syndrome (SIS), and to explore whether the direction of KT affects the therapeutic effect of SIS.MethodsBetween May 2017 and March 2019, 90 participants with SIS in West China Hospital, Sichuan University were randomly divided into three groups, with 30 participants in each group. Participants were treated with KT combined with PRT, and the direction of the KT is from the proximal end of the rotator cuff muscles to the distal end in group A. Participants were treated with KT combined with PRT, and the direction of the KT is from the distal end of the rotator cuff muscles to the proximal end in group B. Participants were treated with PRT alone in group C. Visual Analog Scale (VAS) was used to evaluate the pain in patients at rest, during movement and at night; range of motion (ROM) of shoulder and the disabilities of the arm, shoulder and hand (DASH) outcome questionnaire were used to measure the physical function before treatment and after 1 week and 2 weeks.ResultsAfter 1 week of treatment, ROM of shoulder abduction, internal rotation and DASH scores in group A were significantly improved compared with those in group B and C (P<0.05). After 2 weeks of treatment, the nighttime VAS score, ROM of shoulder abduction, internal rotation and DASH score scores in group A were significantly improved compared with those in group B and C (P<0.05). The VAS score during movement, nighttime VAS score, ROM of shoulder (except external rotation) and DASH score in group A were significantly improved after 1 week and 2 weeks of treatment (P<0.05); and after 2 weeks of treatment, the nighttime VAS score, ROM of shoulder flexion and internal rotation in group B were significantly improved compared with those before treatment (P<0.05). After 2 weeks of treatment, the VAS score during movement, nighttime VAS score, ROM of shoulder (except external rotation) in group C were significantly improved compared with those before treatment (P<0.05).ConclusionKT combined with PRT is more effective than PRT alone in the treatment of SIS, and the therapeutic effect is related to the direction of the tape.
Objective To summarize the current progress in the genetic modification of vascular prostheses and to look forward to the future of genetic modification in vascular prostheses. Methods PubMed onl ine search with the key words of “vascular prostheses, gene” was undertaken to identify articles about the genetic modification of vascular prostheses. Then these articles were reviewed and summarized. Results To improve long-term patency of vascular prostheses, various genes were transfected into seeded cells. The antithrombosis activity of local vessels increased. Conclusion Progresses in tissue engineering and molecular biology make possible endothel ial ization and genetic modification of vascular prostheses. However, because most relevant researches are still basic experiments, further study is needed before cl inical appl ication.

ObjectiveTo investigate the effect of 24-week intradialytic progressive resistance exercise on hemoglobin and iron metabolism in maintenance hemodialysis (MHD) patients.MethodsFrom April to May 2019, 62 MHD patients were enrolled and randomly assigned into exercise group (n=31) and control group (n=31). Both groups of patients received regular routine hemodialysis, on that basis, patients in the exercise group completed intradialytic resistance exercise three times per week for 24 weeks. Each exercise included 8-10 muscle groups (grasping the grip ring with both hands, flexion and extension of the elbows and shoulders on the non-vascular side and lower limbs with sandbag), 3 sets of 15 repetitions with a rest of 1-2 min between 2 sets. Exercise began with a low load, the sandbag weight was gradually increased, and the Borg score was aimed to be 11-13 points after exercise. Hemoglobin, serum ferritin, transferrin saturation, serum creatinine, high-sensitivity C-reactive protein, urea clearance index, recombinant human erythropoietin (rHuEPO) dosage at baseline and after 24 weeks, as well as the cumulative iron supplement dose and hemoglobin variation of the two groups during the study period were evaluated.ResultsThere were 20 patients in the exercise group and 30 ones in the control group who completed the study. After 24 weeks of progressive resistance exercise, the medium (lower quartile, upper quartile) of the amount of rHuEPO in the exercise group decreased from 6 000 (6 000, 9 000) U/week to 6 000 (4 500, 7 125) U/week (Z=?2.599, P=0.009), while that in the control group had no statistically significant difference (Z=?1.340, P=0.180); there was no statistically difference in hemoglobin, hemoglobin coefficient of variation, serum ferritin, transferrin saturation, or 24-week cumulative iron supplementation between the two groups.ConclusionIntradialytic progressive resistance exercise can reduce the amount of rHuEPO in MHD patients, which is benefitial to optimizing the management of hemoglobin.
