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 To analyze the impact of chronic obstructive pulmonary disease(COPD)on coronary plaque burden in elderly patients.Methods A total of 120 COPD patients admitted to the Hongqi Hospital Affiliated to Mudanjiang Medical University from January 2022 to December 2024 were prospectively enrolled and served as the COPD group.Another 120 healthy volunteers were recruited as the control group during the same period.The general clinical data and coronary plaque burden were compared between the two groups.Pearson linear correlation analysis was used to investigate the correlation between forced expiratory volume in the first second(FEV1)and coronary plaque burden as well as left ventricular ejection fraction(LVEF).Multiple linear regression analysis was employed to identify the influencing factors of total coronary plaque bur-den and calcified plaque burden.Results The COPD group had significantly larger smoking ratio and higher levels of high-sensitivity C-reactive protein(hs-CRP)and IL-6,but obviously lower LVEF and FEV1 levels than the control group(P＜0.01).Notably increased total coronary plaque burden(38.30±8.22 vs 24.61±5.56,P＜0.01),calcified plaque burden(21.11±6.57 vs 12.54±3.65,P＜0.01)and non-calcified plaque burden(17.19±5.39 vs 12.07±3.92,P＜0.01)were observed in the COPD group than the control group.FEV1 was negatively correlated with coro-nary plaque burden,calcified plaque burden,and non-calcified plaque burden,and positively corre-lated with LVEF(P＜0.01).Multiple linear regression analysis showed that FEV1 and IL-6 were influencing factors for both total coronary plaque burden(P＜0.01)and coronary calcified plaque burden(P＜0.01),and FEV1 was an influencing factor of non-calcified plaque burden in coronary arteries(P＜0.01).Conclusion COPD promotes the development of coronary plaque burden.So,for COPD patients,it is necessary to strengthen the monitoring and early prevention of coronary plaque burden.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease characterized by abnormal activation of the immune system, leading to damage of the body′s own tissues and organs. The exact mechanisms underlying the pathogenesis of SLE remain incompletely understood. Increasing evidence underscores the significant role of dietary and nutritional factors in the onset, progression, and management of SLE. Modifications in dietary patterns and nutritional interventions offer a promising strategy for improving clinical outcomes and enhancing the quality of life in patients with SLE. This article synthesizes recent basic and clinical research on the impact of various nutritional elements and dietary approaches on the development, progression, and treatment of SLE. It also explores the mechanisms at different levels, aiming to provide valuable insights for future research in this area.

Objective: To analyze the epidemilogical and seasonal characteristics of foodborne Salmonella-associated diarrhea among children aged 0-6 years in Guizhou Province from 2016 to 2023, so as to provide a basis for the prevention and control of foodborne diseases. Methods: Data were extracted from the Foodborne Disease Survellance System for cases reported between January 1, 2016, and December 31, 2023. The incidence, seasonal characteristics, and peak periods were analyzed by the method of concentration and circular distribution. Results: A total of 6 434 cases of diarrhea in children aged 0-6 years were collected, and 455 cases of Salmonella were detected, with a positive detection rate of 7.07%. Salmonella typhimurium was the main serotype causing diarrhea (59.34%). The peak of the disease was from May 3 to September 30, with certain seasonal characteristics. The highest detection rate was found in children aged 1-3 years (8.66%). Among food types, the positive detection rates of Salmonella were relatively high in other foods (17.39%), fruits and their products (10.22%), infant and toddler foods (10.09%), and aquatic animals and their products (9.80%). The processing and packaging methods of food were mainly home-made (9.38%) and bulk food (7.54%). Conclusions The detection rate of Salmonella in children aged 0-6 years is high in Guizhou Province, with strong seasonal characteristics. The detection rates of other foods, fruits and their products, infant and toddler foods, and aquatic animals and their products are high. Enhanced pathogen surveillance for susceptible populations and high-risk foods, coupled with public health education during summer/autumn, is recommended.

[Objective] To study the molecular biological mechanism for a case of ABO blood group B subtype, and perform three-dimensional modeling of the mutant enzyme. [Methods] The ABO phenotype was identified by the tube method and microcolumn gel method; the ABO gene of the proband was detected by sequence-specific primer polymerase chain reaction (PCR-SSP), and the exon 6 and 7 of the ABO gene were sequenced and analyzed. Homologous modeling of Bw.03 glycosyltransferase (GT) was carried out by Modeller and analyzed by PyMOL2.5.0 software. [Results] The weakening B antigen was detected in the proband sample by forward typing, and anti-B antibody was detected by reverse typing. PCR-SSP detection showed B, O gene, and the sequencing results showed c.721 C>T mutation in exon 7 of the B gene, resulting in p. Arg 241 Trp. Compared with the wild type, the structure of Bw.03GT was partially changed, and the intermolecular force analysis showed that the original three hydrogen bonds at 241 position disappeared. [Conclusion] Blood group molecular biology examination is helpful for the accurate identification of ambiguous blood group. Homologous modeling more intuitively shows the key site for the weakening of Bw.03 GT activity. The intermolecular force analysis can explain the root cause of enzyme activity weakening.

In recent years, prone mechanical ventilation has been widely used to improve oxygenation dysfunction in critically ill patients. During prone mechanical ventilation, the patient's face is compressed for a long time, and due to the difficulty in changing, facial pressure injuries and ocular complications are common and severe. These complications increase patient discomfort, reduce their tolerance and compliance with prone ventilation, and even cause tracheal tube displacement or dislodgement, leading to significant clinical challenges. In order to change this situation, the medical staff of the department of critical care medicine of the Second People's Hospital of Hengshui and the department of critical care medicine of Harrison International Peace Hospital had developed an adjustable facial support pad for prone ventilation, and obtained a National Utility Model Patent of China (ZL 2022 2 3295294.4). The device is composed of a facial support platform, a supporting telescopic foot frame and so on. There are front, back, left and right adjustable tracks below the support cushion platform, which can be adjusted to the best state suitable for the patient's face shape, which can alleviate the facial pressure injuries and ocular complications caused by the different sizes of each patient's face, improve the patient's comfort, and reduce the incidence of facial pressure injury and the occurrence of ocular complications of the patient. The height of the platform is adjusted by the telescopic feet, and there is a hook assembly below, which can be fixed by the clamp of the ventilator tubing, so as to prevent the ventilator tubing from pulling the endotracheal intubation due to the gravity of condensation, resulting in the displacement or even prolapse of the tracheal intubation, and reducing the occurrence of adverse events of tracheal intubation. It is worth promoting in the clinic.
