High-intensity laser therapy combined with targeted hand function training for the treatment of grade 1-2 thumb carpometacarpal osteoarthritis / 中国骨伤

OBJECTIVE@#To explore clinical effect of high-intensity laser therapy(HILT) combined with targeted hand function training on pain and lateral pinch force in grade 1-2 thumb carpometacarpal(CMC) osteoarthritis(OA).@*METHODS@#From April 2020 and April 2022, 42 female patients with thumb CMC OA grade 1 to 2, aged from 58 to 80 years old with an everage of (68.90±7.58) years old were divided into observation group of 21 patients who received HILT and targeted hand function training for 4 weeks, and 21 patients in control group who received ultrashort wave therapy combined with using of an orthosis for 4 weeks. Visual analogue scale(VAS) was applied to evaluate degree of pain, function of finger was evaluated by dynamometer to measure lateral pinch force at baseline, immediately following intervention at 4 and 12 weeks following intervention.@*RESULTS@#VAS and lateral pinch force at immediately and 12 weeks after intervention betwwen two groups were better than that of before intervention(P<0.05). Compared with control group, the degree of pain in observation group improved more(immediately after intervention t=3.37, P<0.05, 12 weeks after intervention t=9.05, P<0.05), lateral pinch force higher than that of control group (immediately after intervention t=-2.55, P<0.05, 12 weeks after intervention t=9.51, P<0.05).@*CONCLUSION@#High-intensity laser therapy combined with targeted hand function training is more effective than traditional methods in improving pain and lateral pinch force in grade 1-2 thumb carpometacarpal osteoarthritis.

Short-term effect evaluation of self-management group projects for chronic disease patients in Suzhou / 公共卫生与预防医学

Objective To evaluate the short-term effect of self-management group project for chronic disease patients in Suzhou. Methods Eight to ten streets / towns were randomly selected from 10 cities and districts under the jurisdiction of Suzhou. Each street / town set up a chronic disease self-management group and carried out group activities. The awareness rate of chronic disease related knowledge, health management behavior and health status of the group members after and before the activities were compared to evaluate the short-term effect of the self-management group project. Results A total of 89 chronic disease self-management groups were set up in Suzhou in 2020. Among them, there were 47 hypertension groups and 42 diabetes groups. A total of 1176 people were surveyed at baseline, and 1161 people participated in the evaluation survey after the group activities. By setting up self-management groups, the awareness rates of chronic disease-related knowledge (BMI range, variety of food intake per day per week, moderate-intensity activity time per week, daily salt intake, harm of excessive salt intake, diagnostic criteria for hypertension, sodium content in low sodium salt, fasting blood glucose criteria, low-density lipoprotein control targets) in hypertension and diabetes patients after the intervention were improved compared with those before the intervention, and the differences were statistically significant (P“self-monitoring blood pressure” increased from 52.80% before the intervention to 66.32%, while the proportion of "having a blood glucose monitoring system at home" increased from 52.80% before the intervention to 66.32%, and the proportion of “self-monitoring blood glucose” increased from 25.67% before the intervention to 38.67%. The percentage of "drinking alcohol in the past 30 days" dropped from 12.14% before the intervention to 8.35%. All these differences were statistically significant. There was no difference in the number of "smoking in the past 30 days" compared with before the activity (P≥0.05). The number of days with poor health resulting from injuries in the past 30 days also decreased but the difference was not statistically significant (P≥0.05). In terms of the severity of depression, the number of people with moderate and severe depression decreased after the intervention, and the number of people who turned into mild depression increased, and the difference was statistically significant (P<0.05). Conclusion The self-management group project for chronic disease patients in Suzhou has achieved good results and is suitable for continued promotion and application in this region.

Clinical results of critical rehabilitation pathway after total knee arthroplasty / 中国骨伤

OBJECTIVE@#To investigate the clinical results of the application of critical rehabilitation pathway in the rehabilitation after total knee arthroplasty.@*METHODS@#From March 2015 to December 2019, 67 patients with total knee arthroplasty (TKA) were included. There were 49 females and 18 males, 42 cases on the left and 25 cases on the right, with an average age of 60 to 81(70.72±5.92) years old. Critical rehabilitation paths included intensive strength and gait rehabilitation exercises. All patients were evaluated before operation and 3, 12 months after operation. The evaluation indexes included stair climbing test (SCT), six minute walk test (6MWT), quadriceps and hamstring strength, range of motion, visual pain scale (VAS), Western Ontario McMasterUniversity Osteoarthritis score(WOMAC).@*RESULTS@#All the patients completed the entire pathway and the assessment. The results of pre-operative, 3 months after surgery and 12 months after surgery were as follows respectively. SCT-up: (16.32±3.58) s, (18.16±2.46) s, (11.00±1.29) s, @*CONCLUSION@#Critical rehabilitation path is safe and effective. The knee function of patients who receive critical rehabilitation path after TKA is significantly improved in the first 12 months after operation.

Recognition of Y Fragment Deletion by Genotyping Graphs after Amplified by PowerPlex® 21 Detection Kit / 法医学杂志

OBJECTIVES@#To recognize the possibility of Y fragment deletion of Amelogenin gene intuitively and simply according to the genotyping graphs.@*METHODS@#By calculating the ratio of total peak height of genotyping graphs, the statistics of equilibrium distribution between Amelogenin and D3S1358 loci, Amelogenin X-gene and Amelogenin Y-gene, and different alleles of D3S1358 loci from 1 968 individuals was analyzed after amplified by PowerPlex® 21 detection kit.@*RESULTS@#Sum of peak height of Amelogenin X allele was not less than 60% that of D3S1358 loci alleles in 90.8% female samples, and sum of peak height of Amelogenin X allele was not higher than 70% that of D3S1358 loci alleles in 94.9% male samples.@*CONCLUSIONS@#The result of genotyping after amplified by PowerPlex® 21 detection kit shows that the possibility of Y fragment deletion should be considered when only Amelogenin X-gene of Amelogenin is detected and the peak height of Amelogenin X-gene is not higher than 70% of the total peak height of D3S1358 loci.
