To understand the current status of psychological therapy and counseling services in mental health institutions in mainland China so as to provide reference basis for developing subsequent relevant policies.

From May to June 2021, the National Mental Health Project Office conducted a survey using a self-designed questionnaire on 3 833 institutions providing psychological therapy and counseling services in 31 provinces in mainland China. The data was collected by the mental health project offices at all levels and submitted to the National Mental Health Project Office.

2 214(57.76%) institutions provided psychological therapy or counseling services to both outpatient and inpatient patients. In 2020, we served over 21.86 million people, with outpatient patients slightly higher than inpatients. 2 685(70.05%) institutions charge fees, of which 1 206(44.92%) reported that their psychological therapy services are included in medical insurance. The fee standards for psychological therapy and counseling services vary greatly among different institutions, with psychological therapy services ranging from 5 yuan RMB to 3 000 yuan RMB per session and psychological counseling services ranging from 5 yuan RMB to 2 400 yuan RMB per session.

Residents have low utilization of psychological therapy or counseling services within medical institutions. The prices of psychological therapy or counseling services vary greatly, and the medical security needs to be deeply implemented.

To analyze the data of public consultation events and corresponding online public opinion on disease prevention and control in Chengdu from 2017 to 2023, so as to provide reference for understanding the public’s demand for public health information and reducing the occurrence of adverse public opinion in disease prevention and control and response to emergency public health events.

Collect information on public consultation events related to Chengdu Center for Disease Control and Prevention from 2017 to 2023, and use Baidu search tool “Baidu Index” to collect public opinion monitoring data during the same period. Statistical analysis was conducted on the distribution of public consultation events and their correlation with the Baidu Index of corresponding keywords using methods such as statistical description, chi square test, and linear correlation.

From 2017 to 2023, a total of 7 253 public consultation incidents were received, with the highest number in 2022 (4 915); 12345 hotline platform calls are the main source, accounting for 58.78% (4 263 cases); The main types of consultations from 2017 to 2019 were vaccination issues; From 2020 to 2023, the consultation related to COVID-19 will account for 90.41% (5 952/6 583), and the questions related to the prevention and control of COVID-19 (χ²=1 092.147, P<0.001) and COVID-19 nucleic acid detection (χ²=45.083, P<0.001) in 2022 have increased respectively compared to 2020-2021; In 2023, the proportion of non-COVID-19 related vaccination issues and disease prevention and control issues will decrease (χ²=459.109, P<0.001) and increase (χ²=13.999, P<0.001) respectively compared with that before COVID-19; Linear correlation analysis showed that the number of questions related to vaccination between the “vaccination” search index (r=0.864, P=0.027), the number of questions related to COVID-19 prevention and control between the “COVID-19” search index (r=0.794, P=0.033) and information index (r=0.872, P=0.010), the number of questions related to COVID-19 vaccination between the “COVID-19 vaccine” search index (r=0.840, P=0.018) and information index (r=0.835, P=0.019), and the number of questions related to COVID-19 nucleic acid detection between the “nucleic acid detection” information index (r=0.972, P<0.001) were positively correlated respectively.

Using public health professional knowledge to answer questions for the public is a targeted form of health education. In daily work, we should pay more attention to public opinion monitoring, understand public needs through multiple channels, strengthen public opinion guidance and risk prediction, continue to carry out publicity and education, and improve public health literacy; When an emergency public health event occurs, it is necessary to promptly disclose the epidemic situation, strengthen prevention and control propaganda and guidance, inform the public of response methods, and continuously optimize prevention and control measures to provide support for disease prevention and control and response to emergency public health events.

To analyze the influencing factors of preventive service cost in Guizhou Province from 2016 to 2022 by using grey correlation degree method.

Based on the accounting results of “SHA2011” and the data of “Guizhou Statistical Yearbook” and “Guizhou Health Statistical Yearbook”, the factors affecting the cost of preventive services in Guizhou from 2016 to 2022 were analyzed by using grey correlation method.

The highest correlation with the cost of preventive services in Guizhou province was the number of health technicians in epidemic prevention and control and maternal and child health institutions (0.826), followed by the gross enrollment rate of higher education (0.735), the number of health technology beds in epidemic prevention and control and maternal and child health institutions (0.730). The lowest correlation was the proportion of tertiary industry in GDP (0.593).

Health resource input has the strongest correlation with the cost of preventive services. Health fund input and public health services are the main influencing factors of the cost of preventive services in Guizhou Province. At the same time, full attention should be paid to the influence of social factors such as economic development, education level, urbanization level and age structure on the cost of preventive services.

To explore the current situation and development trend of coupling and coordination of medical resource allocation and service utilization in traditional Chinese medicine hospitals, to clarify the coordinated development relationship between the two, and to provide reference opinions for promoting the benign interaction between the two and achieving balanced development.

From 2017 to 2021, 11 relevant index data of medical resource allocation and service utilization of TCM hospitals in 30 provinces of China were selected, and the comprehensive development index and relative development degree were used to comprehensively evaluate the allocation and service utilization of TCM hospitals, and the coupling coordination method was used to explore the coupling and coordination relationship and development trend of the two systems.

From 2017 to 2021, the coupling coordination degree of medical resource allocation and service utilization of TCM hospitals in various regions of China decreased, showing a stepwise decreasing pattern from east to west. There were obvious differences in the comprehensive development level of medical resource allocation of traditional Chinese medicine hospitals among regions, and the lag in medical resource allocation had become a constraint for the coordinated development of the western region. The overall structure of the relative development level had changed from “8-13-9” in 2017 to “8-12-10” in 2021, and only 12 provinces would achieve coordinated development.

There is a lot of room for improvement in the coupling and coordination of resource allocation and service utilization of traditional Chinese medicine hospitals in China, and the allocation level of medical resources in traditional Chinese medicine hospitals should be optimized according to local conditions, so as to promote the high-quality development of traditional Chinese medicine hospitals with economy. The improvement strategy of coupling coordination level is dynamically adjusted according to the relative development degree, so as to promote the benign interaction between the two and achieve high-quality coordinated development.

To explore strategies to address the gap and uneven distribution of general practitioner(GP) resources from a provincial perspective, aiming to meet the growing medical needs of the people and advance the reform of the medical and health system.

Based on the provincial GP data from 2013-2022, Kernel density estimation was used to reveal the dynamic evolution of GP resources, while the spatial autocorrelation method was applied to explore their spatial correlation characteristics. Additionally, a spatial econometric model was used to investigate the direct impacts and spillover effects of the factors influencing general practitioner resources.

There is a positive autocorrelation in China’s general practitioner resources. Among the direct effects, urbanization rate and population density have a positive impact on general practitioner resources, while the elderly dependency ratio has a negative impact. In terms of indirect effects, urbanization rate, population density, the proportion of medical and health expenditure in fiscal expenditure, and the number of medical and health institutions all have a negative impact on general practitioner resources.

General practitioner resources in China are not randomly distributed spatially, and the spillover effects of influencing factors in adjacent areas can also impact general practitioner resources. It is recommended to focus on collaboration of medical resources and coordination of medical policies among different regions, promoting cross-regional communication and sharing of general practitioners.

To analyze the chain-mediated roles of intergenerational spiritual support and depression between social participation and cognitive functioning in older adults.

In this paper, we used data from the China Health and Aging Tracking Survey (CHARLS) 2020 to screen 3 737 study participants who met the criteria. Depression and cognitive function were measured using the Center for Streaming Depression Scale (CES-D 10) and the Overall Cognitive Scoring Instrument, respectively. Two-column correlation analyses (Pearson’s correlation analyses) of correlation were used, and multiple mediating effect models were constructed to investigate the mediating effects of intergenerational spiritual support and depression in the impact of social participation activities and cognitive functioning in older adults.

After including control variables such as age, gender, marital status, chronic disease prevalence, and insurance participation, regression analysis showed that older adults’ social participation status had a significant direct effect on their cognitive functioning (β=0.254, P<0.001), while intergenerational spiritual support (β=0.052, P<0.050) and depression status (β= -0.084, P<0.001) also had a significant effect on cognitive function in older adults. The results of mediation effect analysis showed that the simple mediation effects of intergenerational psychiatric support and depression status on the relationship between social participation status and cognitive function in older adults were 0.006(95% CI: 0.001-0.012) and 0.020(95% CI: 0.006-0.036), respectively, and the chained mediation effect was 0.001(95% CI: 0.001-0.004).

This study finds a direct mediating effect of depressive status and intergenerational psychiatric support between social participation status and cognitive functioning in older adults, as well as a chain-mediated effect between the two. Social participation of older adults should be improved, while their cognitive function can be improved by children caring more about their parents and reducing depressive symptoms to delay or prevent the occurrence of cognitive impairment in older adults.

To investigate the causal association between sarcopenia and hypertension and the mediating role of sedentary behavior using Mendelian randomization.

The summary statistical data of sarcopenia-related indicators,sedentary behavior (television watching,computer use and driving) and hypertension were extracted from IEU Open GWAS database website.Univariate Mendelian randomization was used to explore the association between the indicators of sarcopenia and hypertension, and two-step Mendelian randomization was used to investigate whether sedentary behaviors (television watching, computer use and driving) mediated the causal association.

Univariate Mendelian randomization revealed that all four indicators of sarcopenia were negatively associated with hypertension, including appendicular lean mass (OR=0.92, 95% CI: 0.88-0.96), left grip strength (OR=0.78, 95% CI: 0.66-0.92), right grip strength (OR=0.78, 95% CI: 0.66-0.91) and walking pace (OR=0.20, 95% CI: 0.14-0.30). Furthermore, two-step Mendelian randomization showed that television watching partially mediated the causal association between left grip strength (22.92%) and right grip strength (23.62%) and hypertension, respectively.

All four indicators of sarcopenia had negative causal associations with hypertension and that television watching mediated part of the causal association between left and right grip strength and hypertension.

To analyze the relationship between cardiovascular-metabolic complications andbasic activity of daily living(BADL) and instrumental activities of daily living (IADL) in Chinese middle-aged and elderly individuals, and to explore the factors influencing different types of ADLs in this demographic with cardiovascular-metabolic complications.

The effects of cardiovascular-metabolic co-morbidities on ADLs among middle-aged and elderly individuals were investigated using the χ² test and logistic regression model in a sample of individuals aged 45 and older from the 2020 China Health and Elderly Care Tracking Survey.A randomized forest prediction model was developed to investigate the influencing factors of different types of activities of daily living in middle-aged and elderly people with cardiovascular-metabolic co-morbidities, and to predict the importance of each influencing factor.

Among China’s middle-aged and elderly population, 19.75% had at least one cardiovascular metabolic disease (CMD), and 4.18% had cardiovascular metabolic co-morbidities (CMM). The prevalence of BADL impairment was 15.90%, and that of IADL impairment was 17.32%.After adjusting for confounding factors like age and sex, middle-aged and older adults with cardiovascular metabolic co-morbidities had a higher risk of developing impaired ADLs compared to their counterparts without these co-morbidities (BADL: OR=1.662, 95% CI: 1.246-2.216; IADL: OR=2.186, 95% CI: 1.663-2.874).Age, depression, pain distress, life satisfaction, literacy, and participation in social activities were predictive of impaired BADL and IADL in older adults with multiple cardiovascular-metabolic co-morbidities, with good predictive modeling (BADL: AUC=0.804; IADL: AUC=0.761).

Middle-aged and older adults with multiple cardiovascular-metabolic co-morbidities are more likely to experience impairments in ADLs. Healthcare providers should consider the specific conditions and risk factors of this demographic and develop personalized, multidimensional intervention programs focusing on mental health, pain and chronic disease management, and life satisfaction enhancement to prevent ADL decline in those with cardiovascular-metabolic co-morbidities.

To systematically evaluate the incidence of self-harm behavior and self-harm ideation among HIV/AIDS patients, providing evidence-based support for effectively improving their mental health.

A comprehensive search of relevant studies was conducted in databases including CNKI, CBM, VIP, WanFang Data, PubMed, Embase, Cochrane Library, Web of Science, and PsyclNFO, covering literature up to August 20, 2024. Two researchers independently screened the literature, extracted data, and assessed the quality. Meta-analysis was performed using Stata 17.0 software.

A total of 9 studies were included, with a sample size of 17 414. Meta-analysis of the random effects model showed that the combined incidence of self-harm behaviors and self-harm ideation in HIV/AIDS patients was 12.3% (95% CI: 9.2%-15.4%), the incidence of self-harm behaviors was 12.4% (95% CI: 7.2%-17.6%), and the incidence of self-harm ideation was 13.3%(95% CI: 8.2%-18.5%). Subgroup analyses showed that the prevalence of self-harm behaviors and self-harm ideation was higher among HIV/AIDS patients in Asia and was higher in moderate-quality studies than in high-quality studies. In addition, higher prevalence rates were also observed in studies published before 2015, in people aged 18-24 years, and in studies with <50% males, but these results need to be interpreted with caution in conjunction with the results of the heterogeneity analysis.

The incidence of self-harm behavior and self-harm ideation is relatively high among HIV/AIDS patients, particularly in Asia. Further research is needed to validate differences among various groups and to develop effective intervention strategies.

To comprehensively analyze the influencing factors of the blood plate-paper bridge method for H antigen induction and identification, and to investigate its mechanism in order to promote the application of this method in Salmonella serotyping.

The experimental conditions of the blood plate-paper bridge method for Salmonella serotyping were optimized by comparing the effects of different paper bridge materials on the induction and identification of H antigen, scanning the surface of different paper bridge materials by scanning electron microscope to explore the mechanism of the effects, and combining the factors of environmental humidity and saline dosage. The optimized method was compared with the simple plate method of GB 4789.4 standard for serotyping 40 strains of Salmonella.

The matte surface of CN110 and CN95 nitrocellulose membranes had similar bridging effect with ordinary filter paper, and the difference was not statistically significant (P>0.05), while the effect of filter membrane was significantly lower than that of ordinary filter paper (P<0.05). Salmonella spread better at higher humidity, and there was a significant difference between the results at 80% humidity compared with those of the 50% and 20% groups (P<0.016 7). The spreading effect was significantly improved with increasing amount of saline (P<0.001), and the optimal amount was 15 μL. Forty foodborne Salmonella strains were identified using the two methods, and the method in this study was able to accurately identify Salmonella serotypes in one go, whereas the simple plate method required one to three inductions.

The blood plate-paper bridge method optimized in this study is easy to operate and has a significant induction effect, which is suitable for the identification of Salmonella serotypes. This method can be used as an effective complement to Salmonella serotyping methods to improve the efficiency and accuracy of foodborne disease traceability.
