ObjectiveTo analyze the output and efficiency of chronic disease management services for hypertension and diabetes in community health service institutions in Shanghai, to evaluate the allocation and efficiency of chronic disease management resources, and to provide references for improving the efficiency of chronic disease management in Shanghai’s communities. MethodsA total of 73 community health institutions from 15 districts of Shanghai were selected. Based on the chronic disease management resource data of community health institutions in 2019, 2021, and 2023, descriptive methods and the BCC model in Data Envelopment Analysis (DEA) were used to analyze the resource allocation, service output, and the efficiency of chronic disease management services in community health institutions in Shanghai. ResultsFrom 2019 to 2023, the indicators of resource allocation and service output of community health service institutions in Shanghai all showed upward trends. In terms of service efficiency, the average number of chronic disease patients managed by each health technician decreased from 237 to 231, and the number of patients served per 1 000 working hours decreased from 54 to 44. DEA efficiency analyses showed that the average overall efficiency increased from 0.867 in 2019 to 0.886 in 2021 and then decreased to 0.811 in 2023. The average technical efficiency decreased from 0.901 to 0.847, which was the main reason for the decline in overall efficiency. The average scale efficiency showed an initial increase followed by a decrease, rising from 0.961 in 2019 to 0.977 in 2021 and dropping back to 0.955 in 2023. The number of strong effective districts (overall efficiency=1.000) decreased from 6 in 2019 to 3 in 2023, and the efficiency differences between districts expanded. The range of overall efficiency widened from 0.622‒1.000 to 0.513‒1.000, indicating a decline in overall efficiency and an increase in inter-district heterogeneity. ConclusionFrom 2019 to 2023, the total volume of resource allocation and service output for chronic disease management in community health service institutions in Shanghai increased continuously. However, both the service output efficiency and the overall resource allocation efficiency declined, driven primarily by a decrease in technical efficiency, and accompanied by widening inter‑district disparities.

Objective:To examine the relationships between perceived organizational support in job resources, self-efficacy in personal resources, and teaching commitment based on the job requirement-resource model, and to explore the path of influencing clinical teachers' teaching commitment.Methods:Using the convenience sampling method, 463 clinical teachers from 16 university-affilicated hospitals in Shandong Province, China were selected as the study subjects. Surveys were conducted using the Perceived Organizational Support Scale, Self-efficacy Scale, and Teaching Commitment Scale. A statistical analysis was performed using SPSS 26.0. A structural equation model was constructed using AMOS 26.0 to test the mediation effect.Results:①The level of teaching commitment of clinical teachers was relatively high, with a total score of (45.25±9.21) points. The total score of perceived organizational support was (38.22±9.75) points, and the total score of self-efficacy was (112.27±17.30) points. ②Perceived organizational support and self-efficacy were positively correlated with teaching commitment ( r=0.59, r=0.65, both P<0.01). ③ Perceived organizational support had significant and direct positive effects on teaching commitment and self-efficacy ( β=0.36, β=0.51, both P<0.01). Self-efficacy significantly and positively affected teaching commitment ( β=0.47, P<0.01). Self-efficacy played a significant and partial mediating role in the effect of perceived organizational support on teaching commitment (standardized mediating effect value of 0.239, P<0.01), and the mediating effect percentage was 39.83%. Conclusions:Perceived organizational support not only directly predicts clinical teachers' teaching commitment, but also indirectly affects teaching commitment through self-efficacy. University-affiliated hospital administrators should pay attention to clinical teachers' perceived organizational support to improve their self-efficacy and teaching commitment, thereby ensuring teaching quality.

Aim To explore the protective effect of icariin on the damage of tight junctional function of Sertoli cells in naturally aging mice and the related mechanism.Methods 15-month-old C57BL/6J male mice were randomly divided into three groups:aging model group,low-dose and high-dose icariin treatment group(5 and 20 mg·kg-1).Another 1-month-old C57BL/6J male mice were considered as adult control group(n=10).The mice in adult control group and aging model group were given the vehicle(0.5％sodi-um carboxymethyl cellulose solution)by intragastric administration,while the mice in icariin-treated groups were given different concentrations of icariin,respec-tively.After continuous administration of icariin for three months,the testes and epididymis were immedi-ately removed,weighed,and the organ index was calcu-lated.Sperm viability and sperm concentration in epi-didymis were measured.The morphological changes of testes were observed by HE staining.The ultrastructur-al changes of tight junctions of Sertoli cells were ob-served by transmission electron microscopy.The ex-pression levels of tight junction-related proteins ZO-1,Occludin,and Claudin11 of testicular Sertoli cells were detected by Western blot.The expression and localiza-tion of ZO-1,Occludin,Raptor,Rictor,p-70S6K,and p-rps6 were detected by immunofluorescence.Results Compared with the aging model group,icariin signifi-cantly increased testicular weight and its index,and ep-ididymal index,improved sperm viability and increased sperm concentration in naturally aging mice.In addi-tion,icariin improved the degeneration of testicular morphology and the damage of ultrastructure of Sertoli cell tight junction with aging.Furthermore,Western blot results showed that icariin up-regulated the expres-sion of ZO-1 and Occludin,but had no significant effect on the expression of Claudin 11.Immunofluorescence assay showed that icariin up-regulated the expression of Rictor,and down-regulated the expression of p-70S6K,p-rps6 and Raptor.Conclusions Icariin improves the tight junction damage of Sertoli cells in naturally aging mice,and its mechanism may be related to restoring the balance between mTORC1 and mTORC2.

Asthenospermia is one of the important causes of male infertility,and its etiology and pathogenesis are complex.Traditional Chinese medicine(TCM)offers unique advantages in treating this disease.The"kidney deficiency and toxic-stasis"theory reveals the dynamic relationship between kidney essence deficiency and the interaction of toxic-stasis in disease pathogenesis,which can be applied clinically to guide the differentiation and treatment of asthenospermia.The formation of asthenospermia is closely related to the deficiency of kidney essence and the blockage of toxic stasis.The kidney essence is the source of reproductive essence.If the kidney essence is depleted for a long time and the kidney essence is deficient,the essence chamber cannot be enriched,resulting in spermatozoa dysfunction and poor spermatozoa mobility.The poison stasis interferes with the spermatozoa and turns into spermatotoxin,which directly harms spermatozoa fertility and leads to the decrease of spermatozoa mobility.Tongjing Jiedu Formula takes tonifying kidney to supply essence,diuresis and detoxification,activating blood circulation and removing blood stasis as the treatment principle,focusing on tonifying kidney to fill essence and nourishing healthy qi to restore the nourishing effect of kidney essence,and also emphasizes clearing heat and detoxification,activating blood circulation and removing blood stasis,promoting diuresis and dredging collaterals to remove poisonous damp-heat and static blood and harmonize blood and vessel,improving spermatogenic environment and improving sperm vitality to help men have children.This article analyzes the application of Tongjing Jiedu Formula in treating asthenospermia from the perspective of"kidney deficiency and toxic stasis",aiming to provid new ideas and methods for the explanation of the pathogenesis of the disease and TCM treatment.

Objective To investigate the relationship between plasma dipeptidyl peptidase 4 (DDP4) level and the progression of abdominal aortic aneurysm. Methods Forty-three patients with abdominal aortic aneurysm admitted to Baoji Central Hospital from January 2020 to May 2021 were selected. The follow-up was conducted at least 12 months,the absolute measurement of the maximum anterior-posterior diameters of the aneurysm and the rate of progression were obtained based on the first and last computed tomography angiography data,and the patients were divided into the progression group (with the rate of progression≥0.5 mm/year) and the progression-free group (with the rate of progression<0.5 mm/year) according to the rate of the abdominal aortic aneurysm progression. The clinical characteristics of the two groups were compared. Plasma DDP4 levels were detected by enzyme-linked immunosorbent assay. The correlation between plasma DDP4 and the rate of abdominal aortic aneurysm progression was analyzed by Pearson correlation and multiple linear regression. The predictive performance of plasma DDP4 on abdominal aortic aneurysm progression was analyzed by Logistic regression model and receiver operating characteristic (ROC) curve. Results The thickness of intracavitary thrombus (P=0.046) and the rate of abdominal aortic aneurysm progression (P<0.001) in the progression group were greater/faster than those in the the progression-free group,and the plasma level of DDP was significantly higher than that in the progression-free group (P<0.001). Multivariate Logistic regression analysis showed that plasma DDP4 level was an independent predictor of abdominal aortic aneurysm progression (P<0.05). Pearson correlation analysis showed that plasma DDP4 level was positively correlated with the rate of abdominal aortic aneurysm progression (r=0.517,P<0.001). After adjusting for other confounding factors,multiple linear regression showed that there was still a significantly positive correlation between plasma DDP4 level and abdominal aortic aneurysm progression rate (β=0.312,95％CI:0.002 to 0.484,P=0.048). The area under the curve of baseline plasma DDP4 level for predicting abdominal aortic aneurysm progression was 0.840 (95％CI:0.704 to 0.976),with corresponding cutoff value of 13.89 pg/mL,specificity of 85.7％,and sensitivity of 79.3％. Conclusion Elevated plasma DDP4 levels in patients with abdominal aortic aneurysm are associated with a higher risk of aneurysm progression. Plasma DDP4 is expected to be a predictive biomarker for abdominal aortic aneurysm progression.
