Objective: To investigate the epidemiological characteristics and spatial-temporal clustering of severe fever with thrombocytopenia syndrome (SFTS) in Huai'an City, Jiangsu Province from 2011 to 2024, so as to provide a basis for optimizing local SFTS prevention and control strategies, and identifying high-risk areas and key populations. Methods: Data on SFTS incidence and deaths in Huai'an City from 2011 to 2024 were collected from the Infectious Disease Reporting Information System of the Chinese Disease Prevention and Control Information System. The reported incidence, mortality, and fatality rates were calculated. Descriptive analysis was performed on temporal, population, and regional distribution. The average annual percent change (AAPC) was used to analyze the trend in the reported incidence of SFTS. Global and local spatial autocorrelation analyses were employed to examine the spatial distribution patterns and spatial association patterns of SFTS incidence while spatio-temporal scanning analyses was used to assess the spatial-temporal clustering of SFTS. Results: A total of 337 SFTS cases were reported in Huai'an City from 2011 to 2024, with the reported incidence rising from 0.17/100 000 to 1.88/100 000. There were 20 deaths, with an average annual mortality of 0.03/100 000, and a fatality rate of 5.93%. The incidence showed obvious seasonality, with a peak in May and June (148 cases, accounting for 43.92%). Spring and summer accounted for 107 cases (31.75%) and 159 cases (47.18%), respectively. The reported SFTS cases were mainly male, farmers, and individuals aged ≥41 years, accounting for 56.38%, 79.23%, and 96.74%, respectively. The population distribution of death cases was basically consistent with that of incident cases. Xuyi County was a high-incidence area, with a total of 332 reported cases, accounting for 98.52%. All death cases were reported in this county. Spatial autocorrelation analyses revealed a positive spatial correlation in SFTS incidence from 2019 to 2024, with Moran's I values ranging from 0.214 to 0.336 (all P<0.05). Heqiao Town, Tianquanhu Town, and Guiwu Town in Xuyi County were identified as high-high clustering areas. Spatio-temporal scanning analyses showed that cluster 1 was consistent with the high-high clustering areas, with an aggregation time from the second quarter of 2019 to the second quarter of 2022. Conclusions From 2011 to 2024, the reported incidence of SFTS in Huai'an City showed an upward trend, with a high incidence in spring and summer. Males, farmers, and the middle-aged and elderly population were the key populations for prevention and control. Xuyi County was the key area for prevention and control.

Objective To analyze the epidemiological characteristics of hepatitis E (HE) in Huai'an City from 2015 to 2024, and construct and validate the prediction effect of the Seasonal Autoregressive Integrated Moving Average (SARIMA) model, and to provide a scientific basis for HE prevention and control. Methods Data of reported HE cases in Huai'an City from January 2015 to December 2024 were extracted from the National Disease Control and Prevention Information System. Descriptive epidemiological methods were used to analyze the temporal, regional and population distribution characteristics of HE incidence. After data preprocessing, stationarity test and randomness test, the SARIMA model was constructed. The optimal model was selected by minimizing the Akaike Information Criterion (AIC). The model performance was evaluated by adjusted R-squared (Adj R²) and root mean square error (RMSE). The monthly incidence rate of HE in Huai'an City in 2025 was predicted and compared with the actual incidence data to validate the model. Results A total of 1 713 HE cases were reported in Huai'an City from 2015 to 2024, showing a fluctuating upward trend. Huaiyin District (339 cases) and Lianshui County (334 cases) were high-incidence areas. The cases were mainly concentrated in people aged 45 and above (83.3%), males (gender ratio 2.37:1) and farmers (70.8%). The optimal model was SARIMA (1,1,1)×(2,0,1)₁₂, with residual as white noise sequence. There was no statistical difference between the actual incidence and predicted value from January to August 2025 (P>0.05). Conclusion HE incidence in Huai'an has obvious aggregation and temporal fluctuation characteristics. The SARIMA model has a good prediction effect, which can provide reference for formulating targeted prevention and control strategies.

Objective To investigate the prevalence of soil-transmitted nematode human infections in Hubei Province from 2016 to 2023, so as to provide insights into formulation of soil-transmitted nematodiasis control strategies and evaluation of soil-transmitted nematodiasis control effectiveness. Methods There were 10 surveillance points established in Hubei Province for soil-transmitted nematodiasis each year from 2016 to 2023. The surveillance points were divided into eastern, western, southern, northern and central regions according to geographical locations, and one administrative village was sampled from a township in each region as a surveillance point. Then, at least 200 permanent residents at ages of over 3 years were randomly sampled at each point, with at least 1 000 individuals sampled. Soil-transmitted nematode infection was detected using a modified Kato-Katz thick smear method (two slides for one stool sample), and Enterobius vermicularis infection was additionally detected with a cellophane tape test among children at ages of 3 to 9 years. The prevalence of soil-transmitted nematode human infections was descriptively analyzed. Results A total of 80 547 individuals underwent surveillance for soil-transmitted nematodiasis in Hubei Province from 2016 to 2023, and a total of 262 individuals were detected with soil-transmitted nematode infections, including two cases with mixed infections, yielding an overall prevalence rate of 0.33% (262/80 547). The prevalence rates of hookworm, Ascaris lumbricoides, Trichuris trichiura, and E. vermicularis infections were 0.02% (20/80 547), 0.07% (55/80 547), 0.02% (15/80 547) and 0.22% (174/80 547), respectively, appearing a parasite species-specific prevalence rate (χ² = 250.235, P < 0.05), and the prevalence rates of soil-transmitted nematode infections were 0.50%(51/10271),0.37%(34/9120),0.39%(39/10099),0.40%(41/10168), 0.36% (37/10 234), 0.45% (46/10 211), 0.03% (3/10 238) and 0.11% (11/10 206) in Hubei Province from 2016 to 2023, respectively, showing a year-specific prevalence rate (χ² = 60.589, P < 0.05). Soil-transmitted nematode infections were detected across 36 surveillance points, and there was a significant difference in the prevalence of soil-transmitted nematode infections among surveillance points (0.02% to 3.30%, P < 0.001). In addition, the differences in prevalence rates of human soil-transmitted nematode infection among different age groups (χ² = 531.091, P < 0.05), occupations (P < 0.001), and education levels (P < 0.001) were all statistically significant. Among these, the children at ages of 3 to 9 years old (1.40%, 174/12 461), nursery-school children (1.69%, 90/5 312) and preschool-aged children (1.56%, 93/5 969) were relatively high. Conclusions The overall prevalence of soil-transmitted nematodiasis was low in Hubei Province from 2016 to 2023; however, the prevalence varied across regions and among populations, with E. vermicularis as the predominant species of soil-transmitted nematode. Soil-transmitted nematodiasis control should be given a high priority in key areas in Hubei Province, and preschool children, primary school students, and individuals with a low educational level are recommended as key target populations for health education and interventions.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To explore the correlation between serum uric acid/high density lipoprotein cholesterol(UHR)and carotid atherosclerosis(CAS)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 322 patients with T2DM admitted to Department of Endocrinology,Tongling People's Hospital were enrolled in this study from November 2021 to March 2023.They were divided into CAS group(n=165)and T2DM group(n=157)according to whether accompanied with CAS.The medical history,physical examination,biochemical examination and UHR were compared between the two groups.Results Compared with T2DM group,the age,SBP,TG,Scr,Cys-C,Hcy,SUA and UHR in CAS group were increased(P<0.01),while HDL-C and HbA1c were decreased(P<0.05 or P<0.01).Pearson or Spearman correlation analysis showed that TG,Scr and Hcy were correlated with UHR(P<0.01).Logistic regression analysis showed that UHR,age and SBP were the independent risk factors of CAS in T2DM patients.ROC curve analysis showed that the sensitivity and specificity of UHR in predicting CAS were 82.40%and 73.90%.Conclusions UHR is the risk factor of CAS in T2DM patients and has a certain predictive value for CAS.

Objective To explore factors affecting blood pressure control in chronic disease patients in China's na-tional basic public health service chronic disease patient management program and to find their relationships with Bayesian network(BN)model,in order to provide a scientific basis for comprehensive hypertension management.Methods 5 577 Hypertensive patients were selected from eight provinces(including autonomous regions)covering eastern,central and western parts of China during a survey from 2021 to 2022.Researchers collected individual and community-management data to screen influencing factors by Logistic regression,and to describe factor dependencies and to identify key determinants of blood pressure control with BN in.blood pressure control.Results Logistic regression revealed that urban/rural status,education,alcohol use,exercise,overweight/obesity and com-munity-doctor advice on salt reduction,smoking cessation were significantly associated with blood pressure control(P＜0.05).The BN model identified 22 directed edges showing that urban residence and good hypertension knowl-edge were more correlated with better control,while community-doctor management and services directly affected patient lifestyle habits but not blood pressure control.Conclusions Research should focus more on urban-rural dis-parities and hypertension education.Additionally,improving patient habits and community-doctor services is essen-tial for better blood pressure control.

Objective:To explore the value of neutrophil extracellular traps (NETs) and interleukin (IL)-33 in the early diagnosis of contrast-induced acute kidney injury (CIAKI).Methods:It was a prospective cohort study. The clinical data of patients who underwent coronary angiography (CAG) in Sir Run Run Hospital, Nanjing Medical University from December 2022 to December 2023 were collected. The main indicators of NETs included myeloperoxidase (MPO), neutrophil elastase (NE), citrullinated histone H3 (H3Cit) and antimicrobial peptide LL-37 amide (LL-37). Serum samples were collected before CAG, and 2 hours and 12 hours after CAG, and the levels of MPO, NE, H3Cit, LL-37, IL-33 and neutrophil gelatinase-associated lipocalin (NGAL) were detected. The differences of clinical data between CIAKI group and non-CIAKI group were compared. Multivariate logistic regression model was applied to analyze the risk factors of CIAKI. The receiver- operating characteristic curve was used to evaluate the predictive performance of biomarkers. Spearman correlation analysis was used to analyze the correlations among those biomarkers.Results:A total of 280 eligible patients with CAG were included in this study, with age of (65±13) years and 203 males (72.5%). The incidence rate of CIAKI was 11.8% (33/280). Compared with non-CIAKI group, the proportions of diabetes ( χ2=5.302, P=0.021), preoperative positive urine protein ( χ2=6.871, P=0.009), taking beta-blockers ( χ2=4.580, P=0.032), diuretics ( χ2=21.987, P<0.001) and calcium channel blocker ( χ2=10.424, P=0.001), preoperative blood glucose ( Z=2.807, P=0.005), preoperative blood urea nitrogen ( Z=2.504, P=0.012), neutrophil at 24 hours after CAG ( Z=2.173, P=0.030), serum creatinine at 24 hours after CAG ( Z=4.000, P<0.001), and blood urea nitrogen at 24 hours after CAG ( Z=4.459, P<0.001) were higher, while the preoperative hemoglobin ( Z=-2.380, P=0.017) and serum albumin ( Z=-2.556, P=0.011) were lower in CIAKI group. Multivariate logistic regression analysis showed that increasing neutrophil at 24 hours after CAG ( OR=1.180，95% CI 1.037-1.341), diuretics ( OR=5.615，95% CI 2.294-13.745) and calcium channel blockers ( OR=3.141，95% CI 1.374-7.182) were independent influencing factors of CIAKI. There were statistically significant differences in the levels of serum NE, MPO, H3Cit, LL-37, NGAL and IL-33 among before CAG, 2 hours after CAG and 12 hours after CAG in the overall population, CIAKI group and non-CIAKI group (all P<0.05). In addition, the changes of IL-33 before CAG and 12 hours after CAG was positively correlated with the changes of MPO, NE, H3Cit, LL-37, NGAL, serum creatinine and blood urea nitrogen before CAG and 12 hours after CAG (all P<0.05). The levels of NE ( Z=3.435, P=0.001; Z=6.164， P<0.001), MPO ( Z=3.627, P<0.001; Z=4.729, P<0.001), H3Cit ( Z=5.174, P<0.001; Z=6.241, P<0.001), LL-37 ( Z=4.986, P<0.001; Z=6.346, P<0.001), NGAL ( Z=2.956, P=0.003; Z=4.263, P<0.001) and IL-33 ( Z=5.056, P<0.001; Z=6.240, P<0.001) in CIAKI group at 2 h and 12 h after CAG were significantly higher than those in non-CIAKI group. The receiver-operating characteristic curve indicated that the combined AUC of neutrophil 24 hours after CAG, diuretics and calcium channel blockers in predicting CIAKI was 0.791. NE ( AUC=0.701), MPO ( AUC=0.712), H3Cit ( AUC=0.777), LL-37 ( AUC=0.767) and IL-33 ( AUC=0.795) at 2 hours after CAG predicted CIAKI relatively well. NE ( AUC=0.865), MPO ( AUC=0.758), H3Cit ( AUC=0.834), LL-37 ( AUC=0.840) and IL-33 ( AUC=0.867) at 12 hours after CAG had better prediction effect for CIAKI. The AUC of NETs combined with IL-33 in predicting CIAKI at 2 hours and 12 hours after CAG was 0.874 and 0.956, respectively. Conclusions:CIAKI patients exhibit elevated levels of NETs and IL-33. Serum MPO, NE, H3Cit, LL-37 and IL-33 at 12 hours after CAG can predict the occurrence of CIAKI. The combination of NETs and IL-33 is more effective in predicting CIAKI.

Patients suffering from nerve injury often experience exacerbated pain responses and complain of memory deficits. The dorsal hippocampus (dHPC), a well-defined region responsible for learning and memory, displays maladaptive plasticity upon injury, which is assumed to underlie pain hypersensitivity and cognitive deficits. However, much attention has thus far been paid to intracellular mechanisms of plasticity rather than extracellular alterations that might trigger and facilitate intracellular changes. Emerging evidence has shown that nerve injury alters the microarchitecture of the extracellular matrix (ECM) and decreases ECM rigidity in the dHPC. Despite this, it remains elusive which element of the ECM in the dHPC is affected and how it contributes to neuropathic pain and comorbid cognitive deficits. Laminin, a key element of the ECM, consists of α-, β-, and γ-chains and has been implicated in several pathophysiological processes. Here, we showed that peripheral nerve injury downregulates laminin β1 (LAMB1) in the dHPC. Silencing of hippocampal LAMB1 exacerbates pain sensitivity and induces cognitive dysfunction. Further mechanistic analysis revealed that loss of hippocampal LAMB1 causes dysregulated Src/NR2A signaling cascades via interaction with integrin β1, leading to decreased Ca²⁺ levels in pyramidal neurons, which in turn orchestrates structural and functional plasticity and eventually results in exaggerated pain responses and cognitive deficits. In this study, we shed new light on the functional capability of hippocampal ECM LAMB1 in the modulation of neuropathic pain and comorbid cognitive deficits, and reveal a mechanism that conveys extracellular alterations to intracellular plasticity. Moreover, we identified hippocampal LAMB1/integrin β1 signaling as a potential therapeutic target for the treatment of neuropathic pain and related memory loss.
