BackgroundFamily functioning is one of the factors influencing non-suicidal self-injury （NSSI） behaviors in adolescents with depressive disorders. Previous studies have treated family functioning as a unitary construct， which may obscure the differential impacts of specific dimensions on NSSI behaviors. ObjectiveTo explore the relationships between various dimensions of family functioning and NSSI behaviors in adolescents with depressive disorders， aiming to provide precise targets for family-based interventions for adolescents with depressive disorders who exhibit NSSI behaviors. MethodsIn this cross-sectional study， 217 adolescent patients who were treated at the outpatient or inpatient department of The First Psychiatric Hospital of Harbin from January to July 2025 and met the diagnostic criteria for depressive disorders as stipulated in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） were included as the research subjects. Assessments included a self-designed questionnaire， the Hamilton Depression Scale-17 item （HAMD-17）， and the Family Assessment Device （FAD）. Univariate Logistic regression analysis was employed to investigate the association between each dimension of family functioning and the NSSI behaviors， and multivariate Logistic regression was used to test the independent effect of each dimension of family functioning on the NSSI behaviors. ResultsA total of 204 cases （94.01%） of adolescent patients with depressive disorders completed the valid questionnaire survey. Among them， 134 cases （65.69%） exhibited NSSI behaviors （NSSI group）， and 70 cases （34.31%） did not exhibit NSSI behaviors （non-NSSI group）. Compared with the non-NSSI group， the NSSI group had a higher HAMD-17 score ［（20.97±7.50） vs. （17.79±6.95）， t=8.705， P=0.004］， a higher FAD total score ［（155.68±21.84） vs. （148.87±22.72）， t=4.348， P=0.038］， and a higher problem-solving dimension score ［（2.54±0.49） vs. （2.34±0.51）， t=7.399， P=0.007］. All the differences were statistically significant. The results of the Logistic regression analysis showed that the FAD total score （OR=1.014， 95% CI： 1.001–1.028， P=0.041） and the problem-solving dimension score （OR=2.241， 95% CI： 1.228–4.090， P=0.009） were both risk factors for NSSI behaviors. After adjusting for gender， age， residence， educational level， monthly family income， and whether being an only child， the correlation between the FAD total score and NSSI behaviors was not statistically significant （OR=1.010， 95% CI： 0.995–1.025， P=0.185）， while the correlation between the FAD problem-solving dimension score and NSSI behaviors remained statistically significant （OR=2.000， 95% CI： 1.028–3.889， P=0.041）. ConclusionImpaired problem-solving capacity within family functioning may constitute a risk factor for NSSI behaviors in adolescents with depressive disorders. ［Funded by Research Project of Heilongjiang Provincial Health Commission （number， 20240303090148， 20230303090154）］

Objective:To analyze the differences in emergency rescue service capacities between county-level hospitals in Zhejiang and Jiangsu provinces, and propose targeted improvement suggestions.Methods:Cluster sampling was employed, with representative county-level hospitals recommended by provincial hospital alliances in Zhejiang and Jiangsu. Emergency departments voluntarily submitted data, resulting in 24 hospitals from Zhejiang and 34 from Jiangsu. Data were collected through the China County-Level Hospital Emergency Service Capability Evaluation System. Differences between provinces were analyzed. Spearman correlation analysis explored relationships between multidimensional indicators, and multivariate logistic regression identified factors influencing hospital grade B++ and above.Results:In terms of department scale, Jiangsu had a larger emergency department area (4 853 m 2vs. 1 927 m 2, P<0.001), more beds of comprehensive inpatient wards in the emergency department (25.5 beds vs. 5.5 beds, P=0.011), and higher scores for the ratio of emergency department area to beds (4.8 vs. 3.4, P=0.005) than Zhejiang. In terms of staffing, Jiangsu had a higher proportion of doctors with master's degrees or above (13.8% vs. 0.0%, P<0.001), a higher proportion of frontline emergency medical staff with over three years of clinical experience (100.0% vs. 91.5%, P=0.001), and more doctors (19 vs. 15, P=0.039) and nurses (46 vs. 32, P=0.039). In terms of quality and safety and medical service capacity, Zhejiang had a higher severe trauma resuscitation success rate (92.9% vs. 83.75%, P=0.003), annual emergency surgery volume (1 002 vs. 428, P=0.015), and number of emergency surgery procedures (125 vs. 42, P=0.027), but Jiangsu had a shorter emergency room stay time (87.5 min vs. 136.2 min, P=0.029). In terms of informatization, Zhejiang outperformed Jiangsu in all indicators, especially in patient information interconnection and sharing (100.0% vs. 82.4%, P=0.030) and in-hospital diagnosis and treatment timeline (91.7% vs. 73.5%, P=0.043). Correlation analysis showed that the total specialty scale score was significantly positively correlated with the in-hospital emergency rescue service capacity score ( r=0.576) and the staffing score ( r=0.455). The total evaluation score was significantly positively correlated with the informatization total score ( r=0.397) and the pre-hospital emergency rescue service capacity score ( r=0.322). Binary Logistic regression analysis showed that the emergency rescue service capacity score was significantly positively correlated with hospital grade ( B=1.431, P=0.03, OR=4.185, 95% CI:1.152-15.205). For every 1-unit increase in the emergency department area ( B=0.002, P=0.05), the probability of a hospital being upgraded to B++ or above increased by 0.2% ( OR=1.002, 95% CI:1.000-1.004). Conclusions:Both provinces exhibit distinct advantages in emergency department development. Departmental scale and configuration significantly impact emergency service capabilities, while staffing and quality management constitute core elements for improvement. Informatization construction notably enhances emergency service efficiency and quality.

Objective:To understand spatial aggregation of lung cancer mortality and its changing trends over the past fifty years in different counties and districts of Shandong Province from 1970 to 2021.Methods:The mortality data of lung cancer were obtained from the death registration system of Shandong province and three retrospective surveys of death cause. The mortality rate and age-standardized mortality rate were used to describe the changing trend of lung cancer in different years, and the contribution value of population factors and non-population factors in lung cancer mortality change was calculated by the mortality differential decomposition method. GeoDa 1.20 and ArcGIS 10.8 software were used for spatial autocorrelation analysis and visualization map display.Results:The crude mortality rate of lung cancer in Shandong Province showed a significant upward trend from 1970 to 2021, rising from 7.22 per 100 000 in 1970-1974 to 62.73 per 100 000 in 2020-2021, with an increase of 7.69 times. Meanwhile, the standardized mortality rate of lung cancer exhibited a trend of increasing first and then decreasing. The differential analysis of lung cancer mortality in different years revealed that changes in crude mortality rates were the result of the combined effects of demographic and non-demographic factors. The proportion of population factors (aging population) leading to an increase in lung cancer mortality rate rose from 2.12% in 1990-1992 to 40.20% in 2020-2021. From a spatial distribution perspective, there were significant regional differences in lung cancer mortality rates among counties (cities, districts) in Shandong Province across different eras. Compared to the period of 1970-1974, the lung cancer mortality rates in all counties and districts in 2020-2021 showed a considerable increase, and there were noticeable changes in the areas of high-high and low-low clustering of lung cancer mortality rates across different eras.Conclusion:There have been significant temporal and spatial changes in the mortality rate of lung cancer in Shandong Province from 1970 to 2021. The crude mortality rate has shown an upward trend, while the standardized mortality rate increases first and then decreases. The concentration of lung cancer mortality rates in counties and districts has also undergone significant changes.

OBJECTIVE To investigate the current status of infection control departments setting,allocation of in-fection control professionals and their position competence in the secondary,tertiary traditional Chinese medi-cine institutions of Beijing.METHODS The questionnaire survey was conducted for all of the secondary and tertiary traditional Chinese medicine institutions in Beijing by Beijing Traditional Chinese Medicine Hospital Infection Man-agement Quality Control Center from Feb.17,2023 to Apr.11,2023.The content of the survey involved the in-formation of the hospitals,setting information of infection control departments and allocation of infection control professionals.RESULTS Totally 59 traditional Chines medicine medical institutions were involved in the survey,35(59.32％)were tertiary hospitals.The median of opened beds was 331(155,479)in the first quarter of 2023.The median of equipped infection control professionals was 4(3,5).The number of infection control professional e-quipped in 67.80％of the medical institutions conformed to requirements of"Notice regarding to further strength-en the management of infection control professionals allocation in medical institutions"released by The Joint Pre-vention and Control Mechanism of the State Council for the Response to the Novel Coronavirus Pneumonia Epi-demic in Aug.2021,with the ratio of infection control professionals to beds 1∶94.20.The principals in charge of the infection control department who had the qualifications for senior professional and technical position and en-gaged in infection control for more than 5 years accounted for 20.00％.Among the infection control professionals,nurses accounted for 49.17％,doctors 41.67％,other professionals 9.17％.CONCLUSIONS There is relatively adequate quantity of the infection control professional equipped in the secondary and tertia-ry medical institutions of Beijing,however,the principals in charge of the infection control department who had the qualifications for senior professional and technical position and engaged in infection control for more than 5 years are very scarce.It is necessary to further optimize the structure of the infection control professionals.

The female reproductive system is essential for sustaining reproductive endocrine homeostasis,however,its vulnerability to various endogenous and exogenous insults,including pathological conditions,pharmacological agents,genetic predispositions,and environmental factors,often results in compromised fertility.The existing protective approaches(including surgical interventions,hormonal replacement therapies,and assisted reproductive techniques)are constrained by several limitations,such as adverse therapeutic effects,technical complexities,and their incapacity to reverse ovarian senescence.Artemisinin and its derivatives(ARTs),characterized by their unique endoperoxide bridge configuration,have exhibited outstanding therapeutic performance across multiple domains including malaria treatment,anticancer therapy,inflammation modulation,and parasitic infection control.Emerging research has identified their novel protective capabilities against various reproductive system pathologies.This comprehensive review systematically elucidates the molecular mechanisms underlying artemisinin-based interventions in reproductive pathologies and evaluates their clinical translation prospects,thereby proposing innovative strategies for the development of next-generation fertility-protective agents with enhanced safety and efficacy profiles.

Objective:To explore the spatial clustering of the mortality rate of cervical cancer in different counties (cities, districts) in Shandong Province from 1970 to 2021 and its 50-year changing trend, so as to provide basis for the implementation and evaluation of prevention and control strategies and programs such as cervical cancer screening, early diagnosis and treatment, human papilloma virus (HPV) vaccination, etc.Methods:The mortality data of cervical cancer were obtained from the death registration system of Shandong Province and the data of three retrospective surveys of death causes. The mortality rate and age-standardized mortality rate (using the population composition of China in 1964) are used to describe the changing trend of cervical cancer in different years. The contribution values of population factors and non-population factors in cervical cancer mortality change are calculated by mortality differential decomposition method. ArcGIS 10.8 software is used for spatial distribution and spatial autocorrelation analysis.Results:From 1970 to 2021, the crude mortality rate and age standardized mortality rate of cervical cancer in Shandong Province showed a trend of first rapid decline and then slow increase. The crude mortality rate and standardized mortality rate of female cervical cancer in Shandong Province in 1970-1974 were the highest, reaching 17.22/10 5 and 13.17/10 5, respectively. In 2004-2005, it dropped to the lowest levels of 1.50/10 5 and 0.83/10 5. Subsequently, it slowly rose to 4.12/10 5 and 1.56/10 5 in 2020-2021. The differential analysis of cervical cancer mortality in different years found that the change of cervical cancer mortality was caused by the combined action of population factors and non-population factors. Among them, demographic factors (aging population) led to the increase of cervical cancer mortality, but non-demographic factors (early diagnosis and treatment, HPV infection level, medical technology level, etc) lead to the decrease of cervical cancer mortality. Compared with 1970-1974, with the passage of time, the absolute values of the contribution values of population factors and non-population factors showed an increasing trend, while the contribution of non-population factors was greater than that of population factors, which led to the decline of cervical cancer mortality. From the perspective of spatial distribution, there were great regional differences in the mortality rate of cervical cancer in different counties of Shandong Province. In 2020-2021, the mortality rate of cervical cancer in all counties decreased to a great extent compared with that in 1970-1974, and the high-high and low-low concentration areas of cervical cancer mortality in different years changed obviously. The high-aggregation areas of the cervical cancer mortality rate in Shandong Province from 2020 to 2021 were mainly distributed in some counties and districts of Linyi City, Zaozhuang City, and Heze City in the southwest. Conclusions:There are significant temporal and spatial changes in the mortality rate of cervical cancer in Shandong Province from 1970 to 2021. According to these trends and their geographical and spatial clustering, prevention and control strategies of cervical cancer in different regions should be further formulated and evaluated.
