ObjectiveTo investigate the influenza vaccination coverage among kindergarten and primary school children in Zhejiang Province in 2023 and analyze the influencing factors, and to provide the basis for improving the effect of influenza vaccination in children. MethodsA multi-stage random cluster sampling method was used to select 3 681 parents of children from 10 primary schools and kindergartens based on economic level and geographical distribution in Zhejiang Province, who participated in an online questionnaire survey, including basic information about the children and their parents, parents’ knowledge about influenza, and their willingness to vaccination. ResultsAmong the 3 681 parents surveyed, 33.82% (1 245/3 681) reported that their children received influenza vaccination in 2023. Multivariate logistic regression analysis showed that factors contributing to children’s influenza vaccination included both parents [adjusted OR (95%CI): 1.56 (1.32‒1.84)] and children [6.04 (5.04‒7.27)] having a history of influenza vaccination, parents’ conviction the influenza vaccine could protect children from severe diseases [1.43 (1.19‒1.74)], and the willingness of most parents would let their children get vaccinated [1.40 (1.13‒1.74)]. In contrast, vaccine hesitancy among parents [0.55 (0.43‒0.69)] and the belief that influenza is just a common cold [0.80 (0.65‒1.00)] were hindering factors. ConclusionThe influenza vaccination coverage among children is insufficient. Both the vaccination history of parents and children, as well as parents’ correct understanding of influenza and the effectiveness of influenza vaccine, significantly influence the influenza vaccination status in children. Efforts to address vaccine hesitancy and misconceptions about influenza are essential to improve vaccination rates.

The rationale for the design of control groups in tuina clinical trial is the foundation for rigorously validating the effectiveness and safety of this therapy. This article reviewed the current state of the design of tuina placebo in control groups of clinical trials， pointed out the necessity of setting up tuina placebo in clinical trials of tuina， analyzed the challenges in implementing blinding of tuina manipulation， and concluded that tuina placebo is still challenged by the placebo effect， the diversification of tuina manipulation but the lack of standardization， and the difficulty of implementing blinding due to the high level of public awareness of tuina. This article also summarized the design of placebo manipulation in three types of clinical trials， including spinal manipulation， acupressure， and paediatric tuina， and proposed four strategies for designing placebo tuina manipulation-controlling placebo effects， developing operational standards for placebo tuina manipulation， ensuring the rigor of blinding implementation， and applying new technologies to enhance the standardization and blinding capacity of placebo tuina methods. So the article is aimed at improving the methodological quality of tuina clinical trial designs， and promoting the standardization and scientificity of tuina clinical trial design.

Objective To analyze the spatial and temporal distribution characteristics of hand-foot-mouth disease (HFMD) in Zibo City, to explore the key incidence areas, and to find a suitable prediction model, so as to provide reference for the prevention and control of HFMD. Methods The spatiotemporal clustering characteristics of HFMD in Zibo City from 2018 to 2023 were analyzed by using SaTScan 10.0.2 software and ArcGIS 10.7 software. A combination model of ARIMA and SVM was established, and the prediction results were verified and compared. Results Spatial clustering analysis showed that there was spatial clustering of the incidence of HFMD in various townships of Zibo City from 2020 to 2022. The high-high clustering areas and Getis-Ord hot spot areas were mainly concentrated in some main urban areas of Zhangdian District, Zichuan District, and Huantai County. A total of 2-5 aggregation areas were detected by spatiotemporal scanning analysis. The first-type aggregation areas were mainly concentrated in the towns of Zhangdian District, Huantai County, Linzi District, Zhoucun District and Gaoxin District. The aggregation months were July, August, September and November. The model prediction results showed that the ARIMA-SVM combined model was more accurate than the traditional ARIMA model. Conclusion There is a spatiotemporal clustering of hand-foot-mouth disease in Zibo City. The ARIMA-SVM combined model can be used to predict the incidence of hand-foot-mouth disease in Zibo City, and to strengthen health education and disease monitoring in high-risk areas and populations during the epidemic months.

Benign liver lesions mainly include hepatic hemangioma， focal nodular hyperplasia of the liver， hepatocellular adenoma， and hepatic angiomyolipoma. Hepatic alveolar echinococcosis is a type of parasitic disease， and since it mainly occurs in the liver， it is also a benign lesion of the liver. The clinical treatment of benign liver lesions is mainly based on follow-up observation， supplemented by surgical resection. For patients with end-stage diseases， liver transplantation can be performed due to the large volume of the lesion， the invasion of a number of surrounding large vessels， unclear anatomic location， and the possibility of intraoperative rupture and massive hemorrhage. Since patients with poor liver function based on the liver allocation score for organ donation are more likely to get donor liver， it is difficult for patients with benign liver lesions to obtain the corresponding donor liver resources due to the growth pattern of benign liver lesions， thereby leading to the limited application of allogeneic liver transplantation. Since its emergence in the 1980s， ex vivo liver resection and autotransplantation （ELRA） has brought a new way for the treatment of such patients. This article summarizes the current application of ELRA in benign liver lesions， in order to provide a reference for diagnosis and treatment by clinical medical staff.

ObjectiveTo analyze the epidemiological characteristics of pathogens in foodborne disease cases in Haining City， Zhejiang Province， and to provide a basis for the prevention and investigation of foodborne diseases and outbreak events. MethodsInformation on foodborne disease patients from 2014 to 2023 was collected， and stool or anal swab samples were tested for relevant pathogens. The χ² test was used to compare the differences in pathogen detection rates among different groups， and multivariate logistic regression analysis was used to analyze the risk factors for pathogen detection. ResultsA total of 5 814 samples were tested， with a positive detection rate of 15.36%. The detection rates were 4.95% for norovirus， 4.49% for Escherichia coli， 3.59% for Salmonella， 2.22% for Vibrio parahaemolyticus， and 0.11% for Shigella. The positive detection rates showed seasonal characteristics， with a minor peak in March-April dominated by norovirus and a major peak in July-September dominated by bacteria. The three groups with the highest detection rates were workers， white-collar workers and other groups. Multivariate logistic regression analysis showed that age， season， and antibiotic use before consultation were significant influencing factors for pathogen detection （P<0.05）. Total pathogen detection risk was lower in the group that took antibiotics before visiting the clinic compared to those who did not （OR=0.29， 95%CI： 0.15‒0.49）. The detection risk for norovirus was lower in the preschool age group （OR=0.19， 95%CI： 0.04‒1.00）， in summer and autumn （OR range 0.23‒0.41）， and in the group taking antibiotics （OR=0.42， 95%CI： 0.15‒0.92）， but higher in the adolescent group （OR=1.40， 95%CI： 1.05‒1.88）. The detection risk for enteropathogenic Escherichia coli was higher in summer （OR=1.82， 95%CI： 1.30‒2.60）. The detection risk for Salmonella increased in the elderly group and in summer （OR range 1.44‒2.21）， but decreased in the adolescent group， in winter， and in the group taking antibiotics （OR range 0.22‒0.65）. The detection risk for Vibrio parahaemolyticus increased in summer and autumn （OR range 1.80‒1.90）， but decreased in the primary and secondary school student group and in winter （OR range 0.10‒0.32）. ConclusionThe prevalence of foodborne disease pathogens in Haining City is relatively high. Age， season， and antibiotic use before consultation are independent influencing factors for pathogen detection. These findings suggest that specific hypotheses regarding pathogenic factors can be proposed based on the time of occurrence and the age distribution of cases during field investigations of foodborne outbreaks.

【Objective】 To explore the correlation between abnormal thalamic functional connectivity (FC) and memory loss in maintenance hemodialysis patients with end-stage renal disease (ESRD). 【Methods】 An auditory verbal learning test (AVLT-H) was conducted on 22 patients with ESRD and 28 age-, sex-, and education-matched healthy controls (HC) to evaluate memory function. After that, resting-state functional magnetic resonance imaging (rs-fMRI) data were gathered, and a whole-brain FC analysis centered on the thalamus was executed to discern variations in thalamic FC between the two groups. Finally, Pearson and Spearman correlation analyses were carried out. 【Results】 Compared to the HC group, the ESRD group exhibited notably lower scores in IR-S (P=0.002), SR-S (P<0.001), and LR-S (P=0.005). Concurrently, the ESRD group demonstrated diminished FC of the right thalamus with the left superior frontal gyrus, the left parietal lobule, the right suproccipital gyrus, the right anterior cuneus, and the right middle frontal gyrus (P<0.05, TFCE correction). Additionally, reduced FC were observed between the left thalamus and the left gyrus rectus, the left parietal lobule, and the right parietal lobule in the ESRD group (P<0.05, TFCE correction). Moreover, the FC values between the left thalamus and the left gyrus rectus in the ESRD group displayed significant negative correlations with IR-S (r=-0.499), SR-S (r=-0.458), and LR-S (r=-0.455) (all P<0.05). 【Conclusion】 Memory impairment is evident in ESRD patients undergoing maintenance hemodialysis, and it appears to be intricately linked to anomalous FC within the left thalamus and the left gyrus rectus. These findings offer potential imaging markers for monitoring memory dysfunction in individuals with ESRD.

Objective To investigate the expression of neutrophil extracellular traps (NETs) and phagocytic function in the peripheral blood of patients with hepatic alveolar echinococcosis (HAE), and to examine their correlations with clinical inflamma tory indicators and liver functions. Methods A total of 50 patients with HAE admitted to Department of Hepatobiliary and Pancreatic Surgery, The Affiliated Hospital of Qinghai University from August 2022 to June 2023 were enrolled, while 50 age- and gender-matched healthy individuals from the Centre for Healthy Examinations of the hospital during the same period served as controls. The levels of NETs markers neutrophil myeloperoxidase (MPO) and neutrophil elastase (NE) were measured using enzyme-linked immunosorbent assay (ELISA). Peripheral blood neutrophils were isolated using density gradient centrifugation, stimulated in vitro using phorbol 12-myristate 13 acetate (PMA), and the levels of MPO and citrullination histone H3 (CitH3) released by neutrophils were quantified using flow cytometry. The phagocytic functions of neutrophils were examined using flow cytometry. In addition, the correlations of MPO and NE levels with clinical inflammatory indicators and liver biochemical indicators were examined using Spearman correlation analysis among HAE patients. Results The peripheral blood plasma MPO［(417.15 ± 76.08) ng/mL vs. (255.70 ± 80.84) ng/mL; t = 10.28, P < 0.05］, NE［(23.16 ± 6.75) ng/mL vs. (11.92 ± 3.17) ng/mL; t = 10.65, P < 0.05］and CitH3 levels［(33.93 ± 18.93) ng/mL vs. (19.52 ± 13.89) ng/mL; t = 4.34, P < 0.05］were all significantly higher among HAE patients than among healthy controls, and a lower phagocytosis rate of neutrophils was detected among HAE patients than among healthy controls［(70.85 ± 7.32)% vs. (94.04 ± 3.90)%; t = 20.18, P < 0.05］, and the ability to produce NETs by neutrophils was higher among HAE patients than among healthy controls following in vitro PMA stimulation. Pearson correlation analysis showed that the phagocytosis rate of neutrophils correlated negatively with platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), interleukin-6 (IL-6) level and C-reactive protein (CRP) level (r_s = −0.515 to −0.392, all P values < 0.05), and the MPO and NE levels positively correlated with inflammatory markers NLR, PLR, CRP and IL-6 (r_s = 0.333 to 0.445, all P values < 0.05) and clinical liver biochemical indicators aspartic transaminase, alanine aminotransferase, direct bilirubin and total bilirubin among HAE patients (r_s = 0.290 to 0.628, all P values < 0.001). Conclusions Excessive formation of NETs is found among HAE patients, which affects the phagocytic ability of neutrophils and results in elevated levels of inflammatory indicators. NETs markers may be promising novel biomarkers for early diagnosis, monitoring, and severity assessment of liver disease.

Objective:To investigate the clinical manifestations, endoscopic characteristics, and prognostic factors of patients with colorectal extranodal NK/T cell lymphoma.Methods:The clinical data of 52 patients with colorectal extranodal NK/T cell lymphoma admitted to the First Affiliated Hospital of Zhengzhou University from January 2013 to January 2023 were retrospectively analyzed. Their clinical manifestations and endoscopic characteristics were summarized, and the prognostic factors were analyzed by Cox regression model.Results:Among the 52 patients with colorectal extranodal NK/T cell lymphoma, there were 35 males and 17 females, with a male-to-female ratio of 2.06∶1. Among the general symptoms, abdominal pain was the most common (39 cases), and B symptoms occurred in 47 patients, among which fever was the most common lymphoma B symptom (42 cases), and gastrointestinal perforation was the most common complication (18 cases). Forty-three patients underwent colonoscopy, and the main manifestations under endoscopy were the ulceration type (24 cases). The ulcers were irregular at the edges and often covered with moss at the bottom. The median survival time was 4.3 months. Multivariate Cox regression analysis showed that hemocytic syndrome ( HR=8.50,95% CI: 1.679-8.328, P=0.001), serum albumin ( HR=3.59,95% CI: 1.017-6.551, P=0.048), and with or without chemotherapy ( HR=0.31, 95% CI: 0.246-1.061, P=0.025) were independent factors influencing the overall survival of patients with colorectal extranodal NK/T cell lymphoma. Conclusions:Colorectal extranodal NK/T cell lymphoma is a rare disease with a very poor prognosis. When patients present with abdominal pain and lymphoma B symptoms, and when ulcers with irregular edges and moss covering the bottom are found under endoscopy, the disease should be considered, and endoscopic biopsy should be taken in time for pathological diagnosis. The prognosis of patients with hemophagocytic syndrome and hypoproteinemia is poor. This disease should be treated with chemotherapy and surgery, and on this basis, hemophagocytic syndrome and hypoproteinemia should be treated to improve the prognosis of patients.
