OBJECTIVETo assess the effects of moxibustion at Shenque (CV8) in promoting gastrointestinal function recovery in rats following gastric perforation repair and explore the underlying mechanism.

METHODSThirty male SD rats with glacial acetic acid-induced gastric perforation underwent surgical repair of the perforation. The rats were then randomized 8 days later into model group (n=10), domperidone group (n=10), and moxibustion group(n=10) and treated with physiologic saline, domperidone suspension, and moxibustion at Shenque (CV8), respectively. Gastric antral myoelectric activities of the rats were observed and peripheral blood levels of TNF-α, IL-6, and T lymphocyte subpopulation were determined.

RESULTSGastric antral myoelectric activities in rats receiving moxibustion were stronger than those in the model group (P<0.05) but comparable with those in domperidone group (P>0.05). TNF-α and IL-6 level were decreased significantly and T lymphocyte subpopulations increased significantly in moxibustion group compared with those in the model and domperidone groups (P<0.05).

CONCLUSIONMoxibustion at Shenque (CV8) can promote the recovery of gastrointestinal functions in rats undergoing gastric perforation repair possibly by enhancing gastrointestinal electric activity, suppressing inflammation, and improving the cellular immune function, and can therefore serve as a simple and effective adjuvant therapy during the perioperative period.

Objective To evaluate the risk of disease of Vibrio parahaemolyticus in aquatic products of raw food animals for population in guangzhou,and determine risk management points. Methods VP quantitative detection was carried out in aquatic products of raw food animals sold in Guangzhou from 2009 to 2022.sQMRA was applied to assess Vibrio parahaemolyticus risk of aquatic products of raw food animals. According to stratified analysis based on the pollution of Vibrio parahaemolyticus and evaluation results,carry out risk management and analysis. Results Among the 98 samples were detected positive of VP from 1 343 samples from 2009 to 2022 , with an overall positive rate of 7.30%.The number of Vibrio parahaemolyticus infection cases caused by eating aquatic products of raw food animals in Guangzhou was 3012. If the proportion of raw food is reduced , the number of Vibrio parahaemolyticus infection cases will be significantly reduced. The number of cases caused by eating raw fash will be reduced from 2128 to 217.The detection rate of Vibrio parahaemolyticus in raw fresh water products was much higher than that in marine products. The probability of infection in the population was higher. The number of cases caused by eating raw fash was the highest.The detection rate of Vibrio parahaemolyticus was higher in raw crustaceans and molluscs. The incidence of Vibrio parahaemolyticus infection cases caused by eating raw fash in the four quarters varied from high to low as such sequence ,4.93×10^-5 in the three quarters , 2.53×10^-5 in the second quarter , 2.40×10^-5 in the first quarter ,1.77×10^-5 in the fourth quarter . Conclusion The risk of disease of Vibrio parahaemolyticus in aquatic products of raw food animals was higher. The public health education should be done well. Aquatic products should be cooked thoroughly before eating . Reduce the intake of raw aquatic products and avoid cross contamination. Focus on the risks of summer and autumn seasons and seafood such as crustaceans and molluscs. Concentrate on scientific research on Vibrio parahaemolyticus pollution of fresh water products.

Objective To understand phthalic acid esters pollution of daily consumed food in Guangzhou City，and evaluate the hazard of phthalic acid esters exposure in residents dietary. Methods Detected the content of phthalic acid esters in 10 types of food by gas chromatography-mass spectroscopy（GC-MS）methods .It combined with a survey on dietary nutrients intake of Guangzhou residents was conducted．Hazard index on the dietary exposure assessment of chemicals in food was applied. Results It showed that the highest levels of DBP，DEHP and DIBP，from the mixed diet samples in Guangzhou were 1.256，1.418，0.576 mg/kg respectively；and the exposure level of DBP，DEHP and DIBP were 2.431、5.981、2.408μg/kg.d ;HQ was respectively 0.243、0.125、0.025. HI was 0.393. Conclusion The dietary contamination of phthalic acid esters for Guangzhou was kept at a low level.But the pollution of 3 kinds of mixed samples such as meats，eggs，aquatic and products may be a certain risk of health that should attract more attention.
