Objective To investigate the effects of electroacupuncture at"Zusanli"(ST36)on type 3 innate lymphoid cells(ILC3s)secreting interleukin(IL)-22 and intestinal cholinergic neurons in the colon of mice with inflammatory bowel disease(IBD),and to explore the mechanisms underlying electroacupuncture-mediated amelioration of IBD.Methods Twenty-four male C57BL/6J mice were divided into a normal group(n=8)and a modeling group(n=16)using the random number table method.The modeling group received 4％dextran sulfate sodium solution ad libitum for 7 days to establish the IBD model.On the fourth day after modeling,the modeling group was divided into a model group and an electroacupuncture group using the random number table method,with eight mice per group.Electroacupuncture intervention was applied bilaterally at"Zusanli"(ST36)in mice of the electroacupuncture group,once daily for 20 min each time,for seven consecutive days.After intervention,stool characteristics and occult blood were assessed.The disease activity index(DAI)of mice in each group was scored,and colon length was measured.The morphology of the colon tissue in mice was observed using hematoxylin-eosin staining,and the histopathological score was determined.A cytometric bead array was used to detect the contents of IL-1β,tumor necrosis factor-α(TNF-α),and IL-6 in colon tissue.Flow cytometry was used to determine the IL-22+ILC3s proportion in lamina propria lymphocytes of colon tissue.The content of IL-22 in colon tissue was detected using an enzyme-linked immunosorbent assay.Immunofluorescence was used to detect the number of choline acetyltransferase(ChAT)+/cellular Fos(c-Fos)+co-labeled neurons in colon tissue.Results Compared with the normal group,mice in the model group exhibited different degrees of loose stools,strongly positive fecal occult blood test,elevated DAI scores,shortened colon length,increased colon histopathological score;increased contents of IL-1β,TNF-α,and IL-6 in colon tissue;and a decreased IL-22+ILC3s proportion in lamina propria lymphocytes of colon tissue(P＜0.05).Compared with the model group,mice in the electroacupuncture group exhibited improved fecal traits,weakly positive fecal occult blood test,decreased DAI score,increased colon length,reduced colon histopathological score;decreased contents of IL-1β,TNF-α,and IL-6 in colon tissues;an increased IL-22+ILC3s proportion in lamina propria lymphocytes of colon tissue;increased IL-22 content in colon tissue;and increased ChAT+/c-Fos+co-labeled neurons in colon tissue(P＜0.05).Conclusion Electroacupuncture at"Zusanli"(ST36)can significantly ameliorate colonic damage and reduce inflammatory responses in IBD mice,and its mechanism may be related to the activation of intestinal cholinergic neurons and the enhancement of colonic ILC3s function.

Objective:To explore the value of morphometric analysis program (MAP) in detecting focus of pediatric epilepsy related to focal cortical dysplasia (FCD) II.Methods:A retrospective analysis was performed; 42 epilepsy children with FCD II and postoperative Engel grading I in Department of Neurosurgery, He'nan Provincial People's Hospital from June 2020 to January 2023 were enrolled. Preoperative MRI data were analyzed by MAP. Difference in general data and focus detection rate by MRI and MAP were compared between the positive MAP group and negative MAP group, and consistency of MAP positive areas (true positive MAP and false positive MAP by postoperative CT) with interictal PET low metabolism positive areas was analyzed.Results:Of the 42 children, 28 had positive MAP and 14 had negative MAP in the epileptogenic focus. Gender was statistically different between positive MAP group and negative MAP group ( P<0.05). MAP had significantly better performance in focus detection compared with MRI (28/42 vs. 19/42, P<0.05). Significant difference was noted between consistency of true positive MAP area with interictal PET low metabolism positive areas (40/43) and that of false positive MAP area with interictal PET low metabolism positive areas (4/33, P<0.05). Conclusion:MAP can improve the focus detection rate of pediatric epilepsy related to FCD II effectively, and PET contributes to rule out false positive results.
