Objective:To investigate the clinical efficacy of radial extracorporeal shockwave therapy(ESWT)for scapulohumeral periarthritis in the elderly.Methods:A total of 82 patients diagnosed with scapulohumeral periarthritis at the rehabilitation medicine department of our hospital from July 2016 to January 2019 were retrospectively analyzed.The visual analogue score(VAS), Constant-Murley score(CMS), range of motion(ROM), adverse reactions, curative effectiveness and survival analysis were examined before treatment and at several time points within 6 months of treatment.Results:Compared with pre-treatment, the VAS, CMS, ROM, curative effects and survival analysis of patients with primary and secondary scapulohumeral periarthritis improved after treatment in both the conventional rehabilitation therapy group and the conventional rehabilitation therapy combined with ESWT group(all P<0.05). The short-term effects(2 weeks and 1 month after treatment)were better in the conventional rehabilitation therapy combined with ESWT group than in the conventional rehabilitation therapy group( P<0.05). There was no significant difference in long-term effects(2, 4 and 6 months after treatment)between the two groups( P>0.05). For patients with primary scapulohumeral periarthritis, conventional rehabilitation therapy combined with ESWT had advantages over conventional rehabilitation therapy in reducing the VAS score and improving shoulder function(CMS score and ROM)( P<0.05). For patients with secondary scapulohumeral periarthritis, conventional rehabilitation therapy combined with ESWT was better in reducing VAS than conventional rehabilitation therapy( P<0.05), while there was no significant difference in shoulder function improvement between the two groups(all P>0.05). Conclusions:Conventional rehabilitation combined with ESWT can relieve shoulder pain, improve range of motion and has a good safety profile in the treatment of scapulohumeral periarthritis in the elderly, but there is no significant difference in long-term efficacy between conventional rehabilitation therapy and conventional rehabilitation therapy combined with ESWT.

Joint contracture is currently one of the very common diseases in rehabilitation medicine department.Once it occurs,it likely leads to such functional disturbances in the patients as restricted joint activities,decreased muscle strength around a joint and abnormal gait,seriously affecting the quality of life of the patients.Studies on its pathogenesis can help doctors better understand and treat the disease.In this paper,pathogenesis of the disease and progress in its therapy are summarized.

Objective To establish a model of knee joint extension contracture in New Zealand white rab-bits, and to lay the experimental foundation for further studies on the pathogenesis and treatment of joint contractures. Methods Thirty male New Zealand white rabbits with mature bones were randomly divided into 6 groups. The left knee joints of the immobilization groups ( 5 groups of 5 rats each) were fixed in extension for 1, 2, 4, 6 or 8 weeks. There was also a control group. At the end of each period the plaster was demolished and the level of transforming growth factor-β1 ( TGF-β1) in joint cavities, the degree of total contracture, myogenic contracture, arthrogenic con-tracture, and the thickness of the posterior joint capsules were measured. The significance of the differences between the immobilized groups and the control group was compared using one-way analysis. Results The level of TGF-β1 in the joint fluid differed significantly among the 6 groups. The differences in the degree of total contracture among the control group, one-week, two-week and four-week groups were also significant. The average degree of the myogenic contracture in the one-week group was significantly different from the other 5 groups' averages. The average myogenic contracture was also of significantly different between the two-week group and the control group. The degree of arthro-genic contracture was significantly different among the groups except for between the 6-week and 8-week groups. The average joint capsule thickness was significantly different among all of the groups except for between the control group and the one-week group. Conclusion This technique for modeling knee extending contracture using New Zealand white rabbits is simple and practical. It provides a better animal model for studying the mechanism of knee joint con-tracture and related treatment strategies and can be used for further exploration of the occurrence and recovery of knee contractures.

Upper gastrointestinal tract cancers originating in the esophagus or esophagogastric junction constitute a major global health problem. On February 28, 2023, National Comprehensive Cancer Network (NCCN) released the clinical practice guidelines for esophageal and esophagogastric junction cancer (version 1.2023). This article will interpret the main updates related to the treatment and follow-up in this version compared to the version 5.2022, in order to provide the Chinese clinicians a better basis and reference for the diagnosis and treatment of the diseases.

The Chinese Standard Aphasia Examination was made according to Chinese language and cultural habits by referring to Japanese Standard Language Test of Aphasia.151 normal people and patients whose brain damaged without aphasia were tested.Mean and standard deviations were calculated.The significant differences were not found by analysis of variance to age,sex,handedness,profession and education except oral instruction and describing pictures in different educational groups.Therefore,the examination is suitable for Chinese aphasics who live in different parts of China and spoken mandarin.

Background Occupational stress and depressive symptoms of disease prevention and control personnel are serious. Objective To investigate the relationship between occupational stress, psychological capital, and depressive symptoms of disease prevention and control personnel, and analyze the potential mediating effect of psychological capital on the relationship between occupational stress and depressive symptoms. Methods From July to September 2020, a cluster random sampling method was used to select 2201 employees from 21 centers for disease control and prevention as study subjects covering all levels of administrative divisions in Jiangsu Province. A total of 2036 valid questionnaires were collected with a recovery rate of 92.5%. The Core Occupational Stress Scale, Patient Health Questionnaire, and Psychological Capital Questionnaire were used to investigate their occupational stress, depressive symptoms, and psychological capital. Stratified regression analysis was used to explore the effects of occupational stress and psychological capital on depressive symptoms. A mediating effect model was used to analyze and verify the potential mediating effect of psychological capital on the relationship between occupational stress and depressive symptoms. Results The total scores in M (P₂₅, P₇₅) of occupational stress, depressive symptoms, and psychological capital in the target population were 42.0 (37.0, 48.0), 8.0 (4.0, 9.0), and 4.6 (4.0, 5.0) respectively. The positive rate of occupational stress was 31.0% (631/2036), and the positive rate of depressive symptoms was 22.0% (448/2036). The dimensional scores of organization and reward, and demand and effort of occupational stress were positively correlated with the total score of depressive symptoms [Spearman correlation coefficients (r_s) were 0.371 and 0.269, P<0.05]. The dimensional scores of social support and autonomy of occupational stress and the score of psychological capital were negatively correlated with the total score of depressive symptoms (r_s=−0.373, −0.112, −0.494, P<0.05). The organization and reward, and demand and effort had positive effects on depressive symptoms (b=0.188, 0.177, P<0.05), while social support and autonomy had negative effects on depressive symptoms (b=−0.290, −0.078, P<0.05), and associated with a 22.5% increase of explanatory variance. Psychological capital had a negative effect on depressive symptoms (b=−0.368, P<0.05), and associated with an 11.0% increase of explanatory variance. Psychological capital had mediating effects on the associations of social support, organization and reward, and autonomy with depressive symptoms, and the mediating effect values were −0.210 (95%CI: −0.253-−0.171), 0.096 (95%CI: 0.071-0.122), and −0.164 (95%CI: −0.229-−0.103), respectively. The corresponding mediating effect percentages were 40.23%, 26.97%, and 45.56%, respectively. Conclusion Occupational stress of disease prevention and control personnel can directly affect depressive symptoms, but also indirectly through psychological capital. Psychological capital plays a partial mediating role in the associations of social support, organization and reward, and autonomy of occupational stress with depressive symptoms. The occurrence of depressive symptoms can be reduced by decreasing occupational stress and increasing psychological capital.
