ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Purpose: Combinations of immune checkpoint inhibitors (ICIs) and chemotherapy have become the standard first-line treatment for human epidermal growth factor receptor 2 (HER-2)-negative advanced gastric cancer. However, primary resistance remains a challenge, with no effective biomarkers available for its prediction. This retrospective study explores the relationship between the baseline inflammatory burden index (IBI) and primary resistance in such context. Materials and Methods: We analyzed 62 patients with HER-2-negative advanced gastric cancer who received ICIs and chemotherapy as their first-line treatment. The IBI was calculated as follows: C-reactive protein (mg/L) × neutrophil count (10 3 /mm 3 )/lymphocyte count (10 3 /mm 3 ). Based on disease progression within 6 months, patients were categorized into the primary resistant or the control group. We compared baseline characteristics and IBI scores between the groups and assessed the predictive value of the IBI using the receiver operating characteristic curve. Both univariate and multivariate binary logistic regression analyses were conducted to identify factors influencing primary resistance. Results: Nineteen patients were included in the primary resistance group, and forty-three patients were included in the control group. The IBI was significantly higher in the resistant group compared to the control group (P<0.01). The area under the curve for the IBI was 0.82, indicating a strong predictive value. Multivariate analysis identified the IBI as an independent predictor of primary resistance (P=0.014). Conclusions The baseline IBI holds promise as a predictor of primary resistance to combined ICIs and chemotherapy in patients with HER-2-negative advanced gastric cancer.

Objective:To investigate the incidence, risk factors, and outcomes of falls among the elderly community population in Beijing.Methods:A cross-sectional survey was conducted using stratified multistage random sampling to select urban and rural residents aged 65 years and older in Beijing. Mortality data was collected after the baseline survey for 5 years. The incidence of falls was weighted based on the composition ratios of age and gender from the 2010 Nation-wide Population Census of Beijing. A logistic regression model was used to analyze the impacts of demographic sociology of common chronic diseases on fall occurrence. The Cox proportional hazards regression model was used to analyze the fall and 5-year survival association.Results:A total of 2 968 participants completed the questionnaire, at cross-sectional survey, with an average age of (73.2±6.0) years, and 1 581 (53.8%) participants were female. Three hundred and sixty-one individuals experienced a fall within the past year. Among those who fell, 64 (17.7%) fell twice, and 95 (26.6%) fell three or more times. Of them, 14.4% (52) had post-fall fractures, with the wrist, knee, and hip being the most common fracture sites, accounting for 25.0%, 17.3%, and 15.4%, respectively. The weighted fall incidence was 12.4% (95% CI: 11.2%-13.5%). Aging, being female, and living in rural areas were more likely to fall. Logistic regression analysis showed that after adjusting for age, gender, and urban-rural status, the risk of falls for those living alone ( OR=1.48, 95% CI: 1.08-2.04) or living with children/grandchildren ( OR=1.51, 95% CI: 1.15-1.97) were significantly higher than those living with their spouse. In addition, the risk of falls was elevated significantly among the elderly with hypertension, diabetes, stroke, dementia, depression status, urinary incontinence, arthritis, insomnia, vision, and hearing loss, dependence on activities of daily living (ADL), general and poor self-rated health (SRH). The Cox proportional hazard regression model revealed that the 5-year risk of death increased by 65% ( HR=1.65, 95% CI: 1.29-2.11) for those who experienced a fall, which increased with fall frequency. This elevated risk persisted after adjusting for chronic conditions, ADL, and SRH. Conclusions:Ageing, female, living in rural regions, having common chronic diseases, dependence on ADL, general and poor SRH, living alone or living with children/grandchildren were associated with the elevated fall risk. The occurrence of fall was seasonal. The most common short-term adverse consequence after a fall was fractures, while the long-term effect was an increased risk of death.

Objective:To investigate the therapeutic efficacy of proximal ulnar osteotomy combined with autologous iliac bone grafting for the repair of chronic elbow varus with posteromedial rotational instability caused by coronoid process bone defects.Methods:A retrospective analysis was conducted on the data of 9 male patients with chronic elbow varus and posteromedial rotational instability caused by coronoid process bone defects who were treated with proximal ulnar osteotomy combined with autologous iliac bone grafting at Sichuan Provincial Orthopaedic Hospital from January 2017 to May 2024. The patients' ages ranged from 20 to 46 years, with an average of 29.78±8.77 years old. There were 3 cases on the right side and 6 on the left side. The height of the bone defect on the anteromedial surface of the coronoid process ranged from 5.24 to 12.23 mm, with an average of 9.01±2.61 mm. The time from injury to surgery ranged from 5 to 9 months, with an average of 6.78±1.39 months. During the operation, proximal ulnar osteotomy combined with autologous iliac bone grafting was used to repair the coronoid process bone defect. Simultaneously, the lateral ulnar collateral ligament was reconstructed using the suture anchors (3 patients) or repaired with autologous palmaris longus tendon (6 patients). Finally, a hinged external fixator was applied in all cases. The range of motion (ROM) of the elbow joint was recorded before and after the surgery. The visual analogue score (VAS) was used to evaluate the degree of pain, and the Mayo elbow performance score (MEPS) was employed to assess the elbow joint function.Results:All surgical incisions healed primarily, and no case of infection occurred. All 9 patients were followed up, with a follow-up period ranging from 11 to 25 months, and an average of 17.78 ± 5.16 months. The bone grafts all healed, with a healing time ranging from 3 to 5 months, and an average of 3.56±0.73 months. The elbow extension angles before surgery, at 6 months postoperatively, and at the last follow-up were 24.44°±14.24°, 11.11°±9.28°, and 2.22°±4.41°, respectively. The flexion angles were 118.89°±5.46°, 123.33°±5.00°, and 128.89°±3.33°, respectively. The flexion-extension ROMs were 94.44°±18.28°, 112.22°±13.02°, and 126.67°±7.07°, respectively. The pronation angles were 61.67°±6.12°, 61.67°±3.54°, and 67.22°±5.07°, respectively. The differences in these angles were all statistically significant ( P<0.05). The supination angles before surgery, at 6 months postoperatively, and at the last follow-up were 77.22°±7.55°, 78.89°±6.01°, and 79.44°±6.35°, respectively. The rotational ROMs were 138.89°±11.93°, 140.56°±7.26°, and 146.67°±10.31°, respectively. No statistically significant differences were observed ( P>0.05). The VAS scores before surgery, at 6 months postoperatively, and at the last follow-up were 6.89±0.78 points, 2.33±1.00 points, and 0(0, 0.5) points, respectively, and the difference was statistically significant ( H=23.216, P<0.001). The MEPS scores were 42.22±5.65 points, 76.67±7.05 points, and 95.00±7.50 points, respectively, and the difference was also statistically significant ( F=134.212, P<0.001). The cantilever test confirmed that none of the patients had elbow joint instability symptoms, and the patients were satisfied with the treatment effect. Conclusions:Proximal ulnar osteotomy combined with autologous iliac bone grafting, simultaneous repair or reconstruction of the lateral ligament complex, and fixation with a hinged external fixator is an effective treatment approach for chronic elbow varus with posteromedial rotational instability. This method can alleviate elbow pain, improve the ROM, and enhance elbow function in patients, yielding satisfactory short-term outcomes.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

OBJECTIVE To analyze the biological characteristics and genomic features of highly lytic bacteriopha-ges isolated from sewage in tropical hospitals and provide references for the hospital-associated infection prevention and control of multidrug-resistant Acinetobacter baumannii(MDR-Ab).METHODS With MDR-Ab as the host bacterium,bacteriophages were isolated from sewage.Transmission electron microscopy was employed to observe their morphology,and determine the optimal multiplicity of infection(MOI),one-step growth curve and environ-mental stability.Whole-genome sequencing and bioinformatics analysis were conducted to annotate functional genes and construct a phylogenetic tree.RESULTS A virulent bacteriophage,HN_Aba_01,was isolated.Elec-tron microscopy revealed that it belonged to the Myoviridae family,with a head diameter of 50 nm and a tail length of 90 nm.This bacteriophage exhibited strong lytic activity,with an optimal MOI of 0.000 000 1,a latent period of 5 minutes and a lysis yield of 15 PFU/cell.It remained stable at temperatures ranging from 4 ℃ to 60 ℃and pH values from 3 to 10.Genomic analysis identified 85 ORFs,including lyase,perforin and depolymerase genes.It shared 98.12％identity with the bacteriophage AbP2 genome(reference genome)and was classified into the Obolenskvirus genus.CONCLUSIONS The bacteriophage isolated from tropical hospital sewage,with high lyt-ic activity and good environmental adaptability,can be used for the hospital-associated infection prevention and control of MDR-Ab.

Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy (GFAP-A) is an immune-mediated inflammatory disease of the central nervous system. However, GFAP-A characterized by progressive encephalomyelitis with rigidity and myoclonus as its predominant clinical phenotype is rare. This article described a case, supplemented with clinical video, of a young male patient who developed fever and neck pain at disease onset. Over the course of the illness, the patient experienced progressively worsening painful muscle spasms, muscle rigidity, and stimulus-sensitive myoclonus, accompanied by autonomic dysfunction. Cerebrospinal fluid analysis revealed positive GFAP-IgG antibodies. The patient showed significant improvement with treatment of high-dose corticosteroids, intravenous immunoglobulin, and mycophenolate mofetil.

AIM:This study aims to explore the mechanisms of influenza A virus(IAV)-induced macrophage inflammatory injury based on the interleukin-6(IL-6)/signal transducer and activator of transcription 3(STAT3)signaling loop and investigate the intervention effects of Ma-Xing-Shi-Gan decoction(MXSGD)-medicated serum.METHODS:RAW264.7 and BV2 cells were divided into control,Janus kinase(JAK)/STAT signaling pathway activator,inhibitor,model,oseltamivir,antiviral particle,and MXSGD groups.After IAV modeling and serum interventions,the cells were cultured for 24 and 48 h,and the indicators were detected and analyzed.ELISA,RT-qPCR,Western blot,and immuno-fluorescence assay were used to detect the secretion levels of IL-6 in the cell culture supernatant,IL-6 and STAT3 mRNA expressions,protein expression of STAT3,and expression levels of phosphorylated STAT3(p-STAT3),respectively.Pearson correlation analysis was used to evaluate the correlation between p-STAT3 and IL-6 in the two cell types.A co-cul-ture model of the two cells was constructed,and the secretion levels of IL-6 in the cell culture supernatant was measured.Molecular docking analyses were performed for STAT3 and MXSGD.RESULTS:After IAV simulation,the secretion lev-els of IL-6 in the cell culture supernatant,mRNA expression levels of IL-6 and STAT3,and protein expression levels of STAT3 and p-STAT3 in both cell lines were elevated(P<0.05 or P<0.01).Pearson correlation analysis revealed that p-STAT3 expression was positively correlated with IL-6 expression.The secretion levels of IL-6 in the co-culture model in-creased(P<0.01).MXSGD down-regulated the secretion levels of IL-6 in the cell culture supernatant mRNA,expression levels of IL-6 and STAT3,and protein expression levels of STAT3 and p-STAT3 in two kinds of cells(P<0.05 or P<0.01),and inhibited the secretion levels of IL-6 in co-culture models.STAT3 demonstrated good binding energies for liquiritin,amygdalin,and ephedrine.CONCLUSION:IAV can induce inflammatory injury in macrophages,and its mechanism may be related to activation of the IL-6/STAT3 signaling loop.MXSGD may alleviate the pathogenic effects of IAV by modulating the signaling loop.
