Objective: To analyze the epidemiological characteristics and trends of other infectious diarrhea among children under 18 years old in Guangzhou City from 2014 to 2020, and to explore the correlation between climatic factors and the incidence of the disease, so as to provide reference for the early prevention of infectious diseases. Methods: The data of cases of other infectious diarrhea and meteorological data of children under 18 years old in Guangzhou City from 2014 to 2020 were collected through the Chinese Infectious Disease Reporting System and the Guangzhou Meteorological Bureau. The correlation between meteorological factors and the incidence of other infectious diarrhea was analyzed using negative binomial regression. Results: A total of 104 566 cases of other infectious diarrhea among children under 18 years old were reported in Guangzhou City from 2014 to 2020, with a male to female ratio of 1.48∶1. The incidence rate was the highest in 2017 (980.83 per 100 000) and the lowest in 2020 (388.22 per 100 000). The peak of incidence occurred from October to March of the following year. Children under 5 years old accounted for 87.95% of all cases. The number of cases of other infectious diarrhea was negatively correlated with the temperature of the previous 6 days ( IRR = -0.07 ), and positively correlated with the temperature difference on the day of onset ( IRR =0.02) (both P <0.05). It was also positively correlated with the wind speed of the previous 7 days ( IRR=0.07, P <0.05), but there was no statistically significant correlation with the relative humidity on the day of onset ( IRR=-0.00, P >0.05). Conclusions Low temperature, large temperature difference, and high wind speed can increase the risk of other infectious diarrhea. It is necessary to strengthen the prediction and early warning in conjunction with meteorological changes, and warn kindergartens and schools to enhance preventive measures against the clustering of other infectious diarrhea cases.

Objective:To investigate the effects of multidisciplinary small-class teaching on expertise and skill acquisition and learning experience in standardized residency training in general surgery.Methods:Sixty residents of grade 2021 rotating in general surgery from January to August 2023 were divided into multidisciplinary teaching group ( n=30) and traditional teaching group ( n=30, to receive tradition one-on-one teaching). All the residents underwent a theoretical examination and Mini-Clinical Evaluation Exercise (Mini-CEX) skill assessment before admission, and the scores were compared between the two groups. At the end of training, the two groups were compared in terms of theoretical and Mini-CEX skill assessment scores and the degree of satisfaction with teaching. Statistical analysis was conducted using SPSS 26.0. Results:There were no significant differences in the theoretical assessment and Mini-CEX skill assessment scores before admission between the two groups ( P>0.05). At the end of training, the multidisciplinary teaching group had a significantly higher theoretical examination score [(88.15±3.45) vs. (72.25±4.36), P<0.05] and a significantly higher Mini-CEX score [(86.35±2.24) vs. (76.28±3.92), P<0.05] compared with the traditional teaching group. According to the survey, the residents in the multidisciplinary teaching group were more satisfied with teaching and more likely to recognize the teaching effects. Conclusions:Multidisciplinary small-class teaching can help improve the quality of standardized general surgery residency training on gastrointestinal tumor treatment, which is a highly accepted and effective attempt at standardized residency training.

Based on network pharmacology and in vitro assays,we conducted a collaborative investi-gation into the protective effects of ginsenosides Rg1 and Re on LPS-induced damage of porcine je-junal epithelial cells IPEC-J2.Network pharmacology was used to obtain and screen the intersec-ting targets of Rg1 and Re to alleviate intestinal barrier damage,and molecular docking technique was used to verify the predicted results of network pharmacology.The experiment included the Control group,LPS group,Rg1 group,and Re group.The effects of different concentrations of Rg1 and Re on cell survival rate,apoptosis rate,TEER value,FD4 permeability,and inflammatory fac-tors of IPEC-J2 were observed,and the effects of different concentrations of Rg1 and Re on the mRNA expression levels of apoptosis-related genes were also detected by fluorescence quantitative PCR.The results of network pharmacology showed that the prevention of intestinal barrier damage by Rg1,Re mainly involved the processes of PI3K-Akt and MAPK signaling pathways.The molec-ular docking results showed that the binding energy of Rg1 to all intersecting targets was less than 0,while that of ginsenoside Re to SRC targets only was less than 0.In vitro experiments showed that pretreatment with different concentrations of Rg1 and Re increased the survival rate and TEER value of LPS-treated IPEC-J2 to varying degrees,and reduced the apoptosis,the decrease of FD4 permeability,and the secretion of inflammatory factor TNF-α,suggesting that Re and Rg1 prevented the intestinal barrier from damage.It was shown that Re and Rg1 could effectively re-duce the effects of LPS treatment on IPEC-J2 cells.Rg1 significantly upregulated the mRNA ex-pression levels of MAPK8,MAPK10,HRAS,and significantly down-regulated the mRNA expres-sion levels of MAP2K1,PIK3CG,IL-2 and SRC;and Re significantly upregulated the mRNA ex-pression levels of MAPK8,MAPK10,HRAS,and PIK3R1,BCL2 gene mRNA expression levels.These results suggest that ginsenosides Rg1,Re and ginsenoside products containing Rg1 and Re deserve further investigation in preventing intestinal barrier damage in piglets.

This study aims to observe the effect of Panax notoginseng extracts on inflammatory re-sponse in immunosuppressed broilers and to investigate the mechanism through network pharma-cology and molecular docking combined with in vivo animal tests.Based on the TCMSP database and GeneCard and other disease databases,we searched for targets related to Panax notoginseng and broiler inflammation,screened key compounds and targets by applying Cytoscape 3.7.1 and String databases,respectively,and constructed a network relationship diagram of traditional Chi-nese medicine(TCM)-key components-targets,and carried out GO functional enrichment and KEGG pathway enrichment analyses by using the DAVID platform.The GO functional enrichment analysis and KEGG pathway enrichment analysis were carried out by the DAVID platform,visual-ized by the Chiplot online website,and finally,the core clustered proteins were analyzed by Pymol software to obtain the core targets,and molecular docking technology was used to predict the de-gree of matching between the active ingredients and the core targets as well as the animal experi-ments to further explore the pharmacological mechanism of Panax notoginseng extracts.Sixty 1-day-old red-feathered broilers were randomly divided into three groups(LPS group,CON group,and PN group),and the test period was 35 days.The LPS and PN groups were injected intraperito-neally with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline on the 12,14,33,and 35 d.The LPS and PN groups were injected with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline.The effect of Panax notoginseng extract on inflammatory cytokines in serum was detected by ELISA,and the hormone content in serum was also detected in each group,and fluorescence quantitative PCR was used to detect the effect of each group on the mRNA ex-pression levels of STAT3,IL-6,and CASP3.The results showed that the serum levels of IFN-γ,IL-6,iNOS,TNF-α,and TNF-β were significantly increased(P＜0.05),while the level of IL-10 was significantly decreased(P＜0.05)after LPS tapping at weeks 2 and 5.The serum levels of IFN-y,IL-6,iNOS,TNF-α,and TNF-β were significantly decreased(P＜0.05)and IL-10 was sig-nificantly increased(P＜0.05)by the addition of Panax ginseng extracts to the basal diet com-pared with the LPS group.Panax notoginseng extracts significantly decreased the serum levels of adrenocorticotropic hormone(ACTH)and corticosterone(CORT)(P＜0.05)and increased the levels of growth hormone(GH)(P＜0.05).A total of 8 active ingredients and 123 potential tar-gets for broiler inflammation were predicted by network pharmacology.The protective mechanism of Panax notoginseng against broiler inflammation may be related to the C-type lectin receptor(CLR)signaling pathway,Toll-like receptor(TLR)signaling pathway,MAPK signaling pathway,NOD-like receptor(NLR)signaling pathway,and FoxO signaling pathway.According to the pre-diction,the alleviation of inflammatory response in broiler chickens by Panax notoginseng may be related to the action on 12 key targets.Fluorescence quantitative PCR showed that Panax notogin-seng extract down-regulated the mRNA expression of IL-6 and CASP3(P＜0.05)and up-regula-ted that of STAT3(P＜0.05),and molecular docking results also showed that the active ingredi-ents in Panax notoginseng extracts could exert anti-inflammatory effects through IL-6 and CASP3.The results suggested that Panax quinquefolium extracts might alleviate the inflammatory response of immune-stressed broilers through multi-components,multi-targets,and multi-path-ways,and this study helps propose new therapeutic strategies and provides a theoretical basis for the development of feed additives based on Penthorum chinense Pursh extract.

BACKGROUND:Chlorfenapyr is used to kill insects that are resistant to organophosphorus insecticides.Chlorfenapyr poisoning has a high mortality rate and is difficult to treat.This article aims to review the mechanisms,clinical presentations,and treatment strategies for chlorfenapyr poisoning. DATA RESOURCES:We conducted a review of the literature using PubMed,Web of Science,and SpringerLink from their beginnings to the end of October 2023.The inclusion criteria were systematic reviews,clinical guidelines,retrospective studies,and case reports on chlorfenapyr poisoning that focused on its mechanisms,clinical presentations,and treatment strategies.The references in the included studies were also examined to identify additional sources. RESULTS:We included 57 studies in this review.Chlorfenapyr can be degraded into tralopyril,which is more toxic and reduces energy production by inhibiting the conversion of adenosine diphosphate to adenosine triphosphate.High fever and altered mental status are characteristic clinical presentations of chlorfenapyr poisoning.Once it occurs,respiratory failure occurs immediately,ultimately leading to cardiac arrest and death.Chlorfenapyr poisoning is difficult to treat,and there is no specific antidote. CONCLUSION:Chlorfenapyr is a new pyrrole pesticide.Although it has been identified as a moderately toxic pesticide by the World Health Organization(WHO),the mortality rate of poisoned patients is extremely high.There is no specific antidote for chlorfenapyr poisoning.Therefore,based on the literature review,future efforts to explore rapid and effective detoxification methods,reconstitute intracellular oxidative phosphorylation couplings,identify early biomarkers of chlorfenapyr poisoning,and block the conversion of chlorfenapyr to tralopyril may be helpful for emergency physicians in the diagnosis and treatment of this disease.
