Objective: To analyze the process of handling a pulmonary tuberculosis(TB) outbreak among senior high school students in a boarding school in Chongqing, as well as to investigate the underlying causes of the outbreak, so as to provide evidence to inform TB prevention and control strategies in school settings. Methods: From November 2023 to April 2024, an epidemiological investigation was conducted into the TB outbreak in a grade 12 class from a boarding high school. Suspected cases were screened using symptom screening, tuberculin skin test (TST), and chest X-ray examinations. Confirmed cases underwent individual epidemiological interviews and sputum culture; Cultured positive mycobacterial strains were subjected to whole genome sequencing after identification as Mycobacterium tuberculosis. Results: A total of 10 active pulmonary TB cases were identified, all from the same class, yielding a student attack rate of 16.67%. Three isolates were culture positive, as well as all strains were of L2 type，and the WGS analysis of the strains suggested a common transmission chain. Excluding the index case, four additional cases were detected through symptom driven health care visits. Notably, 70% of patients presented with "chest tightness and chest pain" symptoms, and 50% had "cough" symptoms,but none were detected during morning health checks or tracking of absences due to illness. A total of 326 contacts were identified and underwent three rounds of screening and one follow up examination. In the initial screening, 35 close contacts from the same class showed strong TST positivity, corresponding to a strong positivity rate of 55.56%, significantly higher than the 20.76% observed among casual contacts ( χ 2=29.80, P <0.01). Among the 35 strongly TST positivvity close contacts and five individuals with moderate TST positivity whose induration had increased by ≥10 mm over two years, none received timely preventive treatment initially; five of them were subsequently diagnosed with active TB within three months. Following this, 25 individuals initiated preventive therapy, resulting in a preventive treatment initiation rate of 62.50%. Among TST negative classmates who converted to strong positivity on repeat TST testing at three months, 75.00% started preventive treatment, but only 22.22% completed the full course. Conclusion Inadequate implementation of morning health checks and cause tracking for absenteeism due to illness, poorly standardized screening procedures, and delayed preventive treatment may have been key factors contributing to the spread of the outbreak.

ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

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: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Objective:To investigate the expression and clinical significance of urinary C-X-C motif chemokine ligand 10(CXCL10)and C-X-C motif chemokine ligand 16(CXCL16)in patients with idiopathic membranous nephropathy(IMN).Methods:A total of 131 patients with IMN(IMN group)who were treated in Zhejiang Provincial Corps Hospital of the Chinese People's Armed Police Force from December 2020 to June 2022 were prospectively selected,131 healthy volunteers(control group)who underwent physical examination during the same period were selected.Patients with IMN were divided into stage Ⅰ group(25 cases),stage Ⅱ group(68 cases),stage Ⅲ group(22 cases)and stage Ⅳ group(16 cases)according to pathological staging,patients were divided into non-remission group(33 cases)and remission group(98 cases)based on the therapeutic efficacy after a 2-year follow-up.Urinary CXCL10 and CXCL16 levels were measured by enzyme-linked immunosorbent assay.Clinical data of patients with IMN were collected,The relationship between urinary CXCL10,CXCL16 levels and pathological staging in patients with IMN was analysied by Spearman/pearson correlation.Multivariate logistic regression analysis influencing factors on non-remission treatment in patients with IMN,and receiver operating characteristic(ROC)curves were used to assess the predictive value Of urinary CXCL10,CXCL16 levels for non-remission treatment in patients with IMN.Results:Urinary CXCL10 and CXCL16 levels in the IMN group were significantly higher than those in the control group(P＜0.05).Urinary CXCL10 and CXCL16 levels were the highest in stage Ⅳ group,urinary CXCL10 and CXCL16 levels in stage Ⅲ group were higher than those in stage Ⅱ group and stage Ⅰ group,and urinary CXCL10 and CXCL16 levels in stage Ⅱ group were higher than those in stage Ⅰ group(P＜0.05).Urinary CXCL10 and CXCL16 levels in patients with IMN were positively correlated with pathological staging,urinary CXCL10 were positively correlated with CXCL16(P＜0.05).Urinary CXCL10 and CXCL16 in non-remission group were higher than those in the remission group(P＜0.05).pathological staging Ⅲ～Ⅳ,elevated 24 h urine protein level,and elevated urinary CXCL10 and CXCL16 levels were independent risk factors for non-remission treatment in patients with IMN(P＜0.05).The areas under the curve(AUC)of urinary CXCL10 and CXCL16 levels for predicting non-remission treatment in patients with IMN alone and in combination were 0.783,0.785,and 0.875,respectively,the combined detection had the highest predictive efficacy(P＜0.05).Conclusion:Urinary CXCL10 and CXCL16 levels are elevated in patients with IMN,it is closely related to the pathological staging of patients and the therapeutic efficacy,the combined detection of urinary CXCL10 and CXCL16 has a high value in predicting the therapeutic efficacy in patients with IMN.

Objective To explore the potential central mechanisms of functional electrical stimulation(FES)hand cycling in promot-ing upper limb motor recovery after stroke.Methods A total of 35 stroke patients hospitalized in the Rehabilitation Center of Changzhou De'an Hospital from May,2023 to December,2024 were enrolled.They sequentially completed 10-minute FES hand cycling and 10-minute sham stimulation(simple hand cycling)tasks.The task order was randomized via dice rolling.Functional near-in-frared spectroscopy(fNIRS)was used to monitor real-time cerebral hemodynamic changes during both tasks to calculate the overall functional connectivity(FC)strength and the FC strength within regions of interest.Results The overall FC strength was higher during the FES hand cycling task than during the sham task(t=2.591,P<0.05),as well as FC between the ipsilateral primary motor cortex(iM1)and ipsilateral somatosensory association cortex(iSAC),iM1 and contralateral somatosensory association cortex(cSAC),ipsilateral pre-motor and supple-mentary motor cortex(iPMC)and iSAC,iPMC and cSAC,iPMC and ipsilateral primary somatosensory cortex(iS1),iPMC and iM1,and contralateral pre-motor and supplementary motor cortex(cPMC)and iSAC(PFDR<0.05).Conclusion FES hand cycling can promote the cortical function remodeling between cerebral hemispheres and the af-fected hemisphere,to integrate sensory-motor function.

Objective To investigate the relationship between serum nesfatin-1(NSF-1)and soluble tumor necrosis factor receptor-Ⅰ(sTNFR-Ⅰ)with premature rupture of membrane(PROM)in patients with severe preeclampsia(SPE),and their effects on pregnancy outcomes.Methods A total of 84 patients diagnosed with SPE in the Obstetrics Department of The First Affiliated Hospital of Nanyang Medical College from April 2023 to April 2024 were selected and grouped into the PROM and non-PROM groups based on whether they had PROM.The pregnant women were separated into good and poor pregnancy groups based on their pregnancy outcomes.Logistic regres-sion analysis was performed to assess the factors influencing PROM in patients with SPE and adverse pregnancy outcomes in patients with PROM.Receiver operating characteristic(ROC)curves were plotted to analyze the value of serum NSF-1 and sTNFR-Ⅰ in the evaluation and prediction of PROM in patients with SPE,as well as adverse pregnancy outcomes in patients with PROM.Results Serum levels of NSF-1 and sTNFR-Ⅰ were significantly higher in the study group than in the control group(P＜0.05).In addition,serum levels of NSF-1 and sTNFR-Ⅰ were significantly higher in the PROM group than in the non-PROM group(P＜0.05).Logistic regression analysis showed that NSF-1 and sTNFR-Ⅰ were risk factors for PROM in patients with SPE(P＜0.05).Based on the ROC curve,the area under the ROC curve(AUC)of serum NSF-1 and sTNFR-Ⅰ levels combined to assess PROM in patients with SPE was 0.887,and the combination of the two was superior to their respective individual predictions(Z=2.601,Z=2.585,both P＜0.05).Serum levels of NSF-1 and sTNFR-Ⅰ in the poor pregnancy group were significantly higher than those in the good pregnancy group(P＜0.05).Logistic regression analysis showed that NSF-1 and sTNFR-Ⅰ levels were risk factors for adverse pregnancy outcomes in patients with PROM(P＜0.05).Based on the ROC curve,the AUC of the combination of serum NSF-1 and sTNFR-Ⅰ for predicting adverse pregnancy outcomes in patients with PROM was 0.908,and the combination of the two was better than their respective individual predictions(Z=2.534,Z=2.556,both P＜0.05).Conclusion Serum levels of NSF-1 and sTNFR-Ⅰ were significantly increased in patients with SPE,and both were related to PROM.Elevated levels of both proteins can increase the risk of adverse pregnancy outcomes.

Aim To investigate the role and underlying mechanisms of transient receptor potential cation chan-nel 6(TRPC6)in epileptogenesis using a kainic acid(KA)-induced mouse model.Methods C57BL/6 and TRPC6-KO(KO)mice were divided into two groups and implanted with cannulas for microinjection of KA(0.03 g·L-1,5 μL)into the lateral ventricle to establish the acute epilepsy model group,with saline injection serving as the control group.The Racine score was used to record the uninterrupted seizure grade of mice within two hours after KA administration.Immunohistochemistry was used to detect neuronal loss and tissue damage in the hippocampus brain region of mice.Immunofluorescence staining,Western blot and qPCR were used to detect the expressions of TRPC6,NLRP3,ASC,Caspase-1,p62,Atg7,Atg5,Beclin-1,LC3b-Ⅱ/LC3b-Ⅰ.in the hippocampus.Results KA induced significant neuronal loss and tissue damage in the hippocampal CA3 brain region of epilep-sy mice,while the expression levels of TRPC6,NL-RP3,ASC and Caspase-1 and other proteins in the hippocampus brain area of epilepsy mice increased,and the protein expression of autophagy-related proteins Atg7,Atg5,Beclin-1,LC3b-Ⅱ/LC3b-Ⅰ increased,while the expression of p62 protein decreased.TRPC6 knockout exacerbated KA-induced epileptogenesis,neuronal injury,inflammatory response and autophagy activation.Conclusion TRPC6 is involved in KA-in-duced epileptigenesis,and the mechanism may be re-lated to the activation of NLRP3 inflammasome-autoph-agy signaling caused by TRPC6 deletion.
