Objective To study the epidemiological characteristics of diarrhea-predominant irritable bowel syndrome (IBS-D) as well as the relationship between the main syndromes and different factors. Method The relevant information of patients were collected by clinical epidemiological method and the relationship between the main characteristics of the IBS-D syndromes and different factors was explored with the major syndromes as the key link. Result Most of the cases aged 30～49 years old. Special hobbies of patients followed by drinking, smoking, addicting spicy, addicting coffee and so on. Poor emotion, mental stress and diet were the main inducements. Liver stagnation and spleen deficiency has the highest percentage (44.7%). The distribution of syndromes in different ages, different genders, different occupations and different education had no significant difference. Conclusion The number of IBS-D hospital visiting-patients is lower than the actual number of illness people. Mental factors are important internal factors, and dietary factors may be an important external factor. Different factors have no effect on the distribution of syndromes.

Objective: To clone hGLP-1 cDNA in the pBS SK(+/-)vector and construct the expression vector of pGEX-4T-3/hGLP-1cDNA to express GST-hGLP-1 fusion protein. Methods: The hGLP-1 cDNA was constructed by 6 synthetic oligonucleotides fragments, followed by the procedure of annealing and ligation with oligonucleotides fragments. The hGLP-1 cDNA was cloned into the pBS SK(+/-) vector, and was selected by α-complementation. It was confirmed by DNA sequening, then inserted into the MCS of the fusion expression vector pGEX-4T-3. The recombinant vector was transformed into E. coli TG1. Results: The recombinant plasmid DNA was digested with restrictive endonuclease BamHⅠand XhoⅠ. The result demonstrated that the hGLP-1 cDNA was successfully inserted into the pGEX-4T-3 vector and fusion protein GST-hGLP-1 had been expressed in SDS-PAGE. Conclusion： Expression of GST-hGLP-1 fusion protein can provide foundation for obtaining a larger quantity of recombinant hGLP-1 for experimental and clinic studies.

BACKGROUND/AIMS: This study was designed to investigate the effect of Fengliao-Changweikang (FLCWK) in diarrhea-predominant irritable bowel syndrome (IBS-D) rats and explore its underlying mechanisms. METHODS: IBS-D model rats were induced by neonatal maternal separation (NMS) combined with restraint stress (RS). In in vivo experiments, the model rats were randomly divided into 5 groups: NMS + RS, FLCWK (low dose, middle dose, and high dose), and pinaverium bromide. The normal control (no handling) rats were classified as the NH group. The therapeutic effect of FLCWK was evaluated by fecal characteristics, electromyographic response and abdominal withdrawal reflex scores. In in vitro experiments, the model rats were randomly divided into 2 groups: NMS + RS, FLCWK (middle dose), and no handling rats were used as the NH group. The differences in basic tension and ACh-induced tension of isolated colonic longitudinal smooth muscle strips (CLSMs) among the 3 groups were observed. In addition, different inhibitors (nifedipine, TMB-8, L-NAME, methylene blue, and 4-AP) were pretreated to explore the underlying mechanisms. RESULTS: In in vivo experiments, fecal characteristics, electromyographic response, and abdominal withdrawal reflex scores significantly improved in the FLCWK group, compared with the NMS + RS group. In in vitro experiments, the basic tension and ACh-induced tension of CLSMs in IBS-D rats were significantly inhibited by FLCWK. After pre-treatment with different inhibitors, the ACh-induced tension of CLSMs in each group showed no significant difference. CONCLUSIONS: FLCWK manifested curative effect in IBS-D rats by inhibiting colonic contraction. The underlying mechanisms may be related to regulatory pathway of nitric oxide/cGMP/Ca2+ and specific potassium channels.

Objective: To analyze the epidemiological characteristics of school foodborne disease outbreaks in Henan Province from 2011 to 2020 and to provide the basis for effective prevention and control of school foodborne disease outbreaks. Methods: The outbreaks of foodborne diseases in schools in Henan Province reported by the foodborne disease outbreak surveillance system from 2011 to 2020 were statistically analyzed. Results: A total of 47 outbreaks of school foodborne diseases were reported in Henan province in the past 10 years, with a total of 1 258 cases, 701 hospitalizations and 1 death. Zhengzhou, Zhumadian, Xinyang and Xinxiang were the top 4 cities in Henan Province in terms of the number of school foodborne disease outbreaks reported. The peak of foodborne illness incidents in schools was in June and September. The largest number of incidents occurred in middle school canteens and primary school canteens(all 12). The number of reported incidents (12) and the number of cases of foodborne diseases (371) in schools caused by cereals and their products were the largest. Pathogenic bacteria and their toxins were the main pathogenic factors that caused the outbreaks of foodborne diseases in schools, accounting for 78.26% of the identified causes. Bacillus cereus was the top pathogens causing foodborne diseases outbreaks in schools. The pathogenic factor that caused the largest number of cases was Diarrheogenic Escherichia Coli, and the pathogenic factor that caused the death cases was poisonous mushrooms. Apart from unexplained incidents, improper processing was the main link leading to foodborne diseases outbreaks in schools. Conclusion The primary and middle school students are the group with high incidence of foodborne diseases in schools. The supervision and management of school canteen should be strengthened in summer to prevent the outbreak of bacterial foodborne diseases caused by improper processing and storage of grain food.
