Objective:To explore the structural relationship between WMSDs in the upper limbs and various risk factors in the occupational population in China, based on a large sample epidemiological survey and structural equation analysis, and to establish a structural equation model, so as to lay a foundation for the prevention and control of such diseases.Methods:The Chinese version of the Musculoskeletal Disorders Electronic Questionnaire was used to conduct a nationwide survey on the prevalence of WMSDs in the upper extremity. Six factors related to WMSDs in the upper extremity were extracted by the classification standard of adverse ergonomic factors and their source and confirmatory factor analysis, including work organization, work type, upper extremity work posture, individual factors, upper extremity fatigue and upper extremity WMSDs. The structural equation analysis was carried out and the structural equation model was established.Results:The incidence of WMSDs and fatigue in the upper limbs was 24.44% and 43.76%, respectively. The adjusted structural equation model fitting indicators were generally up to the standard (GFI=1.000, AGFI=1.000, RMSEA=0.043, NFI=0.808, TLI=0.784) . The four exogenous latent variables of work organization, work type, upper limb work posture and individual factors were correlated. There was a strong positive correlation between job type and upper limb work posture ( r=0.865) , a moderate positive correlation between work organization and job type and upper limb work posture ( r=0.570, 0.490) , and a weak negative correlation between individual factors and the other three exogenous latent variables. Upper limb work posture and individual factors had direct effects on upper limb WMSDs, and the effect coefficients were 0.10 and 0.06, respectively. Upper limb fatigue played a mediating role between work organization, work type, upper limb work posture and upper limb WMSDs. The effect coefficient was 0.46, and the composition ratios of indirect effects were 100.0%, 100.0%, and 38.3%, respectively. The direct path effect of upper limb work posture, individual factors and upper limb WMSDs was weaker than the mediating path through upper limb fatigue. Conclusion:When carrying out the prevention and control of upper limbWMSDs, it is necessary to comprehensively consider the pathogenesis path of upper limb muscle fatigue and upper limb WMSDs caused by work organization, work type, and upper limb work posture, so as to provide theoretical reference for improving the prevention and control level of such diseases.

Objective To explore the effect and safety of right unilateral modified electroconvulsive therapy(RUL-MECT)for major depressive disorder patients(MDD).Methods A randomized controlled trial was conducted on 70 patients with MDD who were randomly divided into a study group and a control group.The study group underwent age-based RUL-MECT,while the control group underwent bitemporal MECT.The participants were evaluated using the 17-item Hamilton depression scale(HAMD-17),MATRICS consensus cognitive battery(MCCB)and orientation recovery tests(ORT).Any adverse reactions that occurred during each intervention process were recorded.Results Before treatment,there were no significant differences in the HAMD-17(32.89±5.68 vs.33.54±4.78)between the two groups(P>0.05).The HAMD-17 score of the intervention group was 6.83±4.68,while the control group was 7.20±4.60 after 8 interventions,repeated measures analysis of variance showed the time effect(P<0.001)was significant.The intergroup effect and interaction effect was not significant(P>0.05).In terms of MCCB scores,there were significant main effect(P<0.001)in connectivity tests,symbol coding,language memory,spatial breadth,number sequence,maze test,visual memory,emotional management and the duration of continuous operation.The intergroup effects of language memory,number sequence,visual memory,speech fluency,and continuous operation were significant(P<0.05).The interaction effect of language memory and continuous operation were significant(P<0.05).After the intervention,the recovery of orientation time was significantly shorter in the study group than that in the control group[(508.57±104.48)s vs.(631.66±212.27)s](P<0.05).The incidence of adverse reactions between two groups(28.6% vs.40.0% )has no significance(P>0.05).Conclusions Compared with bitemporal MECT,RUL-MECT has comparable efficacy in treating depressant and better performance in improving cognitive function and recovery of orientation.

Objective To compare the diagnostic value of adrenocorticotropic hormone(ACTH)stimulation test(AST)with different doses of ACTH combined with midnight administration of 1 mg dexamethasone for the determination of the subtypes of primary hyperaldosteronism(PA).Methods This is a prospective observational study.Patients diagnosed with PA in the Department of Endocrinology,the First Medical Center of of Chinese PLA General Hospital from January 1,2020 to September 30,2022 underwent AST with different doses of ACTH.All patients received 1 mg dexamethasone at midnight for inhibition.Then,the patients were randomly assigned to 25-unit and 50-unit ACTH treatment groups by a ratio of 1:2.Subtype classification and diagnosis of aldosterone-producing adenoma(APA)and idiopathic hyperaldosteronism(IHA)was made on the basis of adrenal venous blood samples and/or postoperative pathology and clinical follow-up findings.Receiver operating characteristics(ROC)curves were plotted to examine the diagnostic efficacy and the difference of AST by varying doses of ACTH in distinguishing APA and IHA.Results A total of 82 patients,including 49 patients with APA(59.8%)and 33 patients with IHA(40.2%),were enrolled.There were 29 patients in the 25-unit ACTH group(35.4%)and 53 patients in the 50-unit ACTH group(64.6%).There were no significant differences in age,sex,blood pressure,minimum serum potassium,and biochemical parameters between the 25-unit and 50-unit groups.After ACTH stimulation,plasma aldosterone concentration(PAC),cortisol(F),and PAC/F at different points of time showed no statistical difference between the two groups(P>0.05).The area under the curve(AUC)of PAC in the 25-unit group was higher than that of PAC/F.The AUC of PAC reached the maximum at 90 minutes(0.948,95%confidence interval[CI]:0870-1.000)and the optimal cutoff was 38.0 ng/dL,which had a sensitivity of 92.9%and a specificity of 86.7%for differentiating APA and IHA.Similar to the 25-unit group,the maximum AUC of PAC in the 50-unit group was greater than that of PAC/F.The AUC of PAC reached the maximum 90 minutes(0.930,95%CI:0.840-0.994)and the optimal cutoff was 39.6 ng/dL,which had a sensitivity of 91.2%and a specificity of 83.3%.The AUC of PAC at different points of time in the 25-unit ACTH group(0.862-0.948)was greater than that of 50-unit ACTH group(0.823-0.930),but the difference was not statistical significance.Conclusion AST with 25-unit or 50-unit ACTH combined with small-dose dexamethasone can be used in PA subtype determination,ie,differentiation between APA and IHA.The optimal PAC cut-off values for 25-unit or 50-unit ACTH are similar,being 38.0 ng/dL and 39.6 ng/dL,respectively,and both cutoff values show higher sensitivity and specificity at 90 min.The AST with 25-unit ACTH has the smaller dose and the better safety.Therefore,it is recommended for the diagnosis of PA subtypes.
