Objective To analyze the case data of farmers' foodborne disease surveillance reports in Guizhou Province from 2022 to 2024, and to provide reference for the precise prevention and control of foodborne diseases among farmers in Guizhou Province. Methods Case data of foodborne disease surveillance reports of farmers were systematically collected from 2022 to 2024 in Guizhou Province. Descriptive epidemiological methods were used to analyze the temporal, geographical, and demographic distribution of foodborne diseases among farmers, along with their primary clinical symptoms and pathogen detection results. Results From 2022 to 2024, a total of 22,882 cases of foodborne diseases were reported among farmers in Guizhou Province. The majority of clinical symptoms (97.81%) were related to the digestive system, with summer being the peak season. While females outnumbered males, the gender difference was statistically insignificant (P >0.05). The 36-55 age group accounted for the highest proportion (38.83%), with Zunyi City (34.89%) and Qiandongnan Prefecture (23.21%) reporting the most cases. Fungal products were the most frequently reported suspected food items (26.96%), and home-made preparation was the primary processing method (58.63%). A total of 1 210 fecal samples were collected through active monitoring with an overall detection rate of 13.22%. Norovirus showed the highest detection rate (9.92%, 120/1 210). Statistically significant differences were observed among different seasons, age groups, regions, types and processing methods of suspected food exposure, and pathogen detection rates (P <0.001). Conclusion Foodborne disease prevention and control among farmers in Guizhou Province should focus on the risks of wild mushroom poisoning in summer and homemade foods, and continuously improve farmers' awareness of the dangers of foodborne diseases and food safety.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

Background::The increasing incidence of inflammatory bowel disease (IBD) presents significant medical and societal challenges. A well-designed IBD database is crucial for both epidemiological studies and clinical management. However, inconsistencies between regional databases hinder cross-institutional and international research, especially between Eastern and Western societies.Methods::We developed a new IBD database, the 301 IBD database, integrating the IBD clinical characteristics from the Penn IBD database (USA) and the latest IBD guidelines and consensus and clinical practices of the Chinese PLA General Hospital (PLAGH). We applied this database to analyze clinical data of IBD inpatients at PLAGH from 2008 to 2023.Results::The 301 IBD database contains 490 items in 6 sections including demographic characteristics, personal history, clinical phenotype, disease activity, laboratory tests and examinations, and treatment. Features of the 301 IBD database include inpatient focus, biochemical indicators and opportunistic infection focus, and more about ulcerative colitis (UC)-associated complications. Single-center analysis revealed an increasing hospitalization trend, from 2.35% in 2008 to 3.94% in 2023. We found that the clinical characteristics of our UC inpatients are predominantly male (62.5%), extensive lesions (55.1%), low usage of biologics (4.1%), and a high incidence of UC-CRC (3.0%). The clinical characteristics of CD inpatients included male predominance (68.39%), early onset age (35.43 ± 14.75-year-old), and high rate of surgery (25.81%).Conclusion::The 301 IBD database, integrating Eastern and Western clinical data, provides a valuable tool for IBD clinical research. Future international, multicenter collaborations are expected to further enhance its utility.

Under the current situation of "low prevalence and low infection" of schistosomiasis in China, and to provide a basis for achieving the goal of eliminating schistosomiasis by 2030 proposed by the Healthy China Action (2019 - 2030) as scheduled, the Hunan Provincial Corps Hospital of the Chinese People's Armed Police Force established a schistosomiasis monitoring and early warning index system based on the previous studies on schistosomiasis early warning index system and the recent literature analysis, combined with the current potential risk factors affecting the transmission and prevalence of schistosomiasis, and organized two rounds of expert consultation and carried out project promotion meetings. The experts reached a consensus on the comprehensiveness and practicability of the index system, aiming to lay a solid foundation for construction of China's schistosomiasis prevention and control early warning system.

Objective:To investigate the efficacy of tiotropium bromide combined with bilevel positive airway pressure (BiPAP) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated by type 2 respiratory failure and its effects on serum level of inflammatory factors in patients.Methods:A total of 90 patients with AECOPD complicated by type 2 respiratory failure admitted to the Department of Respiratory Medicine, The Affiliated Qingdao Third People's Hospital of Qingdao University from June 2021 to June 2023 were included in this study. This study used a randomized controlled design. The patients included were divided into a control group and an observation group ( n = 45/group) using a random number table method. The control group was given conventional treatment in addition to mechanical ventilation using a BiPAP respirator. Patients in the control group used the spontaneous/timed (S/T) mode, which automatically switched between spontaneous breathing and time-controlled ventilation. The observation group received inhalation treatment with tiotropium bromide in addition to the treatment provided to the control group. The efficacy and serum levels of inflammatory factors (high-sensitivity C-reactive protein, tumor necrosis factor-alpha, and interleukin-6) were compared between the two groups. Results:After treatment, the mMRC (Modified Medical Research Council) Dyspnoea Scale score and chronic obstructive pulmonary disease assessment test score in the observation group were (1.40 ± 0.35) and (12.42 ± 2.57), respectively. These values were significantly lower than those in the control group [(2.62 ± 0.55), (19.05 ± 3.13), t = -4.05, -3.65, both P < 0.05]. After treatment, the acute physiology and chronic health evaluation Ⅱ score in the observation group was (13.85 ± 1.24), which was significantly lower than that in the control group [(18.24 ± 1.58), t = -3.92, P < 0.05]. After treatment, oxygen saturation and partial pressure of oxygen in the observation group were (95.18 ± 5.82) % and (84.37 ± 5.54) mmHg (1 mmHg = 0.133 kPa), respectively. These values were significantly higher than those in the control group [(91.42 ± 5.79) %, (72.41 ± 4.79) mmHg, t = 3.99, 3.96, both P < 0.05]. Partial pressure of carbon dioxide in the observation group was (34.37 ± 1.97) mmHg, which was significantly lower than that in the control group [(41.68 ± 2.19) mmHg, t = -3.72, P < 0.05]. After treatment, high-sensitivity C-reactive protein, tumor necrosis factor-alpha, and interleukin-6 levels in the observation group were (13.18 ± 1.43) mg/L, (8.42 ± 1.26) ng/L, and (9.18 ± 1.05) ng/L, respectively. These values were significantly lower than those in the control group [(19.28 ± 2.36) mg/L, (15.76 ± 1.73) ng/L, (19.38 ± 1.61) ng/L, t = -4.22, -5.23, -6.18, all P < 0.05]. The total response rate in the observation group was significantly higher than that in the control group [91.11% (41/45) vs. 73.33% (33/45), χ2 = 5.86, P < 0.05). Conclusions:Inhalation treatment with tiotropium bromide combined with mechanical ventilation using a BiPAP respirator can effectively reduce the severity of dyspnea and alleviate clinical symptoms in patients with AECOPD complicated by type Ⅱ respiratory failure. This combination therapy reduces hypoxia and carbon dioxide retention, diminishes inflammatory response, and enhances overall clinical efficacy.

Subunit 5B of constitutively photomorphogenic 9 signalosome(CSN5B)is an inhibitory factor for the biosynthesis of vitamin C in the L-galactose synthesis pathway in plants.To create mutants with richer vitamin C in tomato fruits,a dual-target vector of pKSE402-SlCSN5Bwas constructed and trans-formed into the breeding parent of 1912.Based on the molecular biological assay and DNA sequencing,17 transgenic positive lines were determined,and 6 lines of them were genetically mutated at the target site of SlCSN5B,with an editing efficiency of 35.3％.Among the mutants,2 lines were homozygous mu-tants,csn5b-6 with 180 bp deletion and csn5b-8 with 3 bp deletion.The biological traits of two types of deficiency homozygotes without exogenous T-DNA insertion derived from the T1 generation were observed,and there were no significant differences in phenotypes of the plant and fruit.Through physiological tes-ting of red-ripe fruits from T,generation lines of csn5b-6,the GMPase activity and the vitamin C content significantly increased by 43％and 37.8％,respectively,the content of hydrogen peroxide significantly decreased by 25.9％,and the content of soluble solids did not obviously change,compared with the wild type.There were no significant differences in plant traits and physiological characteristics between T1 gen-eration lines of csn5b-8 and the wild type.Based on gene expression analysis and protein structure predic-tion,the results showed that the gene of SlCSN5B normally transcribed,and the loss of large peptide seg-ments of CSN5B encoded by SlCSN5B caused changes in its structure to affect functioning,which led to an increase of vitamin C content in the line of csn5b-6-1 1.The findings suggest that the vitamin C content of tomato fruit can be improved by CRISPR/Cas9-mediated SlCSN5B gene editing,which provides the valuable resources for high-quality breeding in tomato.
