Depression is a high-incidence mental disorder with complex causes and multifaceted pathogenic mechanisms. Its pathogenesis has not yet been fully elucidated, which has hindered the development of novel and highly effective antidepressant drugs. This condition severely affects human physical and mental health while imposing a significant socio-economic burden. At present, several hypotheses exist regarding the pathogenesis of depression, including monoamine neurotransmitter imbalances, neurotrophic factor deficiencies, neural plasticity impairments, glutamate dysregulation, neuroinflammatory disorders, gut microbiota imbalances, and mitochondrial autophagy dysfunction. Currently, most clinical antidepressants are monoamine neurotransmitter reuptake inhibitors. Although they exhibit certain therapeutic effects, they are associated with significant drawbacks, such as severe adverse reactions and poor patient compliance. In contrast, traditional Chinese medicine (TCM), characterized by its multi-targeted effects, mild efficacy, and minimal side effects, has demonstrated significant advantages in the treatment of depression. Chinese medicine Polygalae Radix possesses the functions of calming the mind, enhancing cognitive functions, harmonizing the heart and kidneys, and dispelling phlegm to open orifices. It is often included in compound prescriptions for the clinical treatment of depression. Based on current hypotheses regarding the pathogenesis of depression, this paper systematically reviews research progress on the antidepressant mechanisms of Polygalae Radix from multiple perspectives, including its active components, its use in herbal pairings, and its inclusion in TCM compound prescriptions. This review aims to provide a scientific basis for the clinical application of Polygalae Radix in antidepressant therapy and to serve as a reference for the modernization of its antidepressant research.

Objective:
To investigate the prevalence and influencing factors of hepatitis C virus (HCV) infection among drug users in Baoshan District, Shanghai Municipality, so as to provide insights into strengthening HCV intervention among drug users.
Methods:
Drug users under community management in Baoshan District from 2017 to 2023 were recruited. Demographic information, drug use behaviors, sexual behaviors and receipt of intervention service were collected through questionnaire surveys. Blood samples were collected for HCV antibody testing, and the prevalence of anti-HCV antibody was analyzed. Factors affecting the prevalence of anti-HCV antibody among drug users were analyzed using a multivariable logistic regression model.
Results:
A total of 2 801 drug users were surveyed, including 2 233 males (79.72%) and 568 females (20.28%). The majority of drug users were aged 40 to <60 years (1 663 drug users, 59.37%). The prevalence of anti-HCV antibody was 28.35%, showing an overall upward trend from 2017 to 2023 (P<0.05). Multivariable logistic regression analysis showed that females (OR=1.468, 95%CI: 1.169-1.844), 40 years and over (40 to <50 years, OR=2.441, 95%CI: 1.838-3.242; 50 to <60 years, OR=2.377, 95%CI: 1.787-3.161; 60 to 97 years, OR=1.637, 95%CI: 1.163-2.304), using traditional drugs (OR=2.488, 95%CI: 1.967-3.147) or mixed drugs (OR=2.950, 95%CI: 1.974-4.409), having injected drugs (not share needles, OR=3.649, 95%CI: 2.849-4.673; share needles, OR=3.532, 95%CI: 1.851-6.738) and never using condoms during sexual contacts with spouses/cohabitants in the past year (OR=1.975, 95%CI: 1.354-2.879) were associated with a higher prevalence of anti-HCV antibody; the educational level of high school/technical secondary school (OR=0.483, 95%CI: 0.280-0.835) or college and above (OR=0.280, 95%CI: 0.129-0.608) was associated with a lower prevalence of anti-HCV antibody.
Conclusions
The prevalence of anti-HCV antibody among drug users in Baoshan District showed an upward trend from 2017 to 2023. Gender, age, educational level, type of drugs, history of drug injection and never using condoms during sexual contacts with spouses/cohabitants were influencing factors for prevalence of anti-HCV antibody among drug users.

Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.

ObjectiveTo improve the response capabilities to disasters and prevent major epidemics, it is of practical use to study the capability evaluation system of the national emergency medical rescue team that combines theoretical training and practical exercises, to enhance the overall quality of the teams. MethodsFirst, a capability assessment system for the national emergency medical rescue team was constructed based on the INSARAG External Classification (IEC) standards of the national emergency medical rescue team. Then, based on the outcome based education (OBE) concept, we conducted innovative research on the curriculum design and exercise programs for team building and member training. Finally, an empirical analysis was conducted on the effectiveness of the evaluation system and training exercises based on the statistical analysis of the comprehensive quality evaluation of the Shanghai national emergency medical rescue team from 2020 to 2023, as well as the empirical analysis of the rescue exercise on the Cruise of spectrum. ResultsBased on the linear regression analysis of each core competency indicators, the five core competencies in the evaluation system, including rescue skills, medical and health knowledge, disaster coping ability, team cooperation ability, and mental resilience training, were positively correlated with the cumulative number of trainings (r=0.71, r=0.76, r=0.81, r=0.84, r=0.96,all P<0.05), indicating that the training was effective and the course design was reasonable. Empirical cases showed that the three-dimensional rescue drill model had remarkable results in the actual combat application and ability improvement of team members. ConclusionThe training courses and drills designed based on the three-level assessment system are effective in improving the comprehensive capabilities of the national emergency medical rescue team.

Objective By using the computational fluid mechanic(CFD)method the tandem carotid artery stenosis(TCAS)was simulated on the model,and to compare the postoperative hemodynamic changes of different surgical procedures.Methods One patient with tandem stenosis of internal carotid artery(ICA)and common carotid artery(CCA)was selected.CFD technique was used to establish four three-dimensional(3-D)models of the carotid bifurcations,including one model of a real patient and three models of presumptive surgery.The hemodynamic analysis was performed with these models so as to explore the development mechanism of TCAS and to discuss the selection of suitable surgical plan.Results In tandem stenosis,the stenosis was preferentially formed in CCA and subsequently led to ICA stenosis.The local hemodynamic situation in TCAS was more complex and more risky than in single carotid artery stenosis.In tandem stenosis,the treatment of one stenosis site would affect the blood flow at the next stenosis site and cause restenosis or plaque rupture.Conclusion In treating patients with TCAS,CFD simulation examination should be performed when the surgical plan is formulated,which can help clinicians to predict the postoperative changes in blood flow and to choose the appropriate surgical plan.

ObjectiveTo present the exploration and application of a prospective follow-up research method for acute infectious disease surveillance based on natural community populations, using COVID-19 infection as an example, and to provide a reference for improving the infectious disease surveillance and early warning system. MethodsA multi-stage probability proportional sampling method was employed to sample residents from all communities of 16 administrative districts in Shanghai, with households as the units. A cohort for acute infectious diseases based on natural community populations was established. The baseline survey was conducted for all cohort subjects, and COVID-19 antigen test kits were distributed. From December 21, 2022 to September 30, 2023, prospective follow-up monitoring of COVID-19 antigen and nucleic acid was carried out on the study subjects on a weekly basis. The baseline characteristics and follow-up information of the cohort subjects were described. ResultsThe cohort for acute infectious diseases included a total of 12 881 subjects, comprising 6 098 males (47.3%) and 6 783 females (52.7%). The baseline survey revealed that 35.2% (4 540/12 881) of the subjects had a history of COVID-19 infection. During the follow-up period from December 21, 2022 to September 30, 2023, the average incidence density in the cohort was 0.61/person-year, with a higher incidence density in females (0.63/person-year) compared to males (0.59/person-year). Individuals aged 60 and above (0.64/person-year) and those with underlying health conditions (0.67/person-year) had a higher incidence density. Healthcare workers showed a notably higher incidence density (0.84/person-year) than that in other occupational groups. As of September 30, 2023, a total of 340 subjects in the cohort experienced secondary infections, with a median interval of 170 days between the first and second infections. ConclusionThis study applies cohort study method to acute infectious disease surveillance, providing crucial data support for estimating infection rates and forecasting alerts for acute infectious diseases in the community. This method can be promoted and applied as a new approach for acute infectious disease surveillance.
