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 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.

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 discuss the impact of Wenyang lishui formula on ventricular remodeling in rats with pulmonary hypertension-induced right heart failure (RHF) based on the Hippo/Yes-associated protein (YAP) signaling pathway. METHODS Ten rats were randomly selected as the control group. The remaining 63 rats were given a single intraperitoneal injection of monocrotaline to establish the pulmonary hypertension-induced RHF model. The 50 rats that successfully underwent the model establishment were randomly divided into the RHF group, low-dose group of Wenyang lishui formula (4.25 g/kg), high-dose group of the Wenyang lishui formula (17.00 g/kg), furosemide group (20 mg/kg), and high-dose group of Wenyang lishui formula+ Hippo/YAP signaling pathway activator group (17.00 g/kg of Δ Wenyang lishui formula+16 mg/kg of PY-60), with 10 rats in each group. The rats in each group were given the corresponding drug solution or normal saline by gavage or/andtail vein injection, once a day, for 4 consecutive weeks. During the experiment, the general conditions of the rats in each group were observed; after the last administration, the right ventricular diameter, right atrial diameter, end-diastolic volume, pulmonary artery blood flow acceleration time (PAAT) and its ratio to ejection time (ET) (PAAT/ET), pulmonary artery pressure and its ratio to pulmonary arterial flow velocity (pulmonary artery pressure/velocity) were measured. The plasma levels of brain natriuretic peptide and angiotensin Ⅱ (Ang Ⅱ) were detected. The pathological changes of the right ventricular tissue were observed, and the collagen volume fraction, the phosphorylation levels of the large tumor suppressor 1/2 (LATS1/2) and YAP, and the protein expression of the transcriptional coactivator of PDZ-binding motif (TAZ) were also detected. RESULTS Compared with the RHF group, the rats in Wenyang lishui formula low-dose and high-dose groups showed improved hair color, movement, diet, and mental state. The atrophy of right ventricular myocardial cells, the increase of inflammatory cells, collagen deposition, and hypertrophy of myocardial fibers were significantly alleviated. The right ventricular internal diameter, right atrial internal diameter, end-diastolic volume, pulmonary artery pressure, pulmonary artery pressure/velocity, the plasma levels of brain natriuretic peptide and AngⅡ , collagen volume fraction, the phosphorylation level of YAP and protein expression of TAZ were significantly decreased, while the PAAT, PAAT/ET and the phosphorylation level of LATS1/2 were significantly increased (P<0.05). PY-60 could significantly reverse the improvement effects of high-dose Wenyang lishui formula on the above quantitative indicators (P< 0.05). CONCLUSIONS Wenyang lishui formula can restore the right heart function of pulmonary hypertension-induced RHF rats, reduce their pulmonary artery pressure, alleviate the pathological changes in their cardiac tissues, and the above effects may be related to the activation of Hippo expression and the inhibition of YAP phosphorylation.

The observation of eye expression is an important aspect of traditional Chinese medicine diagnosis.Traditional Chinese medicine proposes the original proposition that"the eyes are the messenger of the heart",suggesting that eye expression reflects the external manifestation of mental consciousness and cognitive activities.Research has shown that eye expression can directly reflect brain function and cognitive abilities,serving as a biological marker for pathological changes in brain structure and playing an important role in early diagnosis of mental disorders.In recent years,scholars have paid increasing attention to eye tracking technology as an objective tool for measuring eye expression.This paper outlines the theoretical basis of using traditional Chinese medicine's observation of eye expression for diagnosing mental disorders,and analyzes the current application status of eye tracking technology in diagnosing conditions such as depression,schizophrenia,and autism spectrum disorder.It is hoped that this review will provide insights for future research on applying objective methods to traditional Chinese medicine diagnosis through observing eye expressions.
