Berberine might block colorectal carcinogenesis by inhibiting the regulation of B-cell function by Veillonella parvula / 中华医学杂志(英文版)

BACKGROUND@#Colorectal carcinogenesis and progression are related to the gut microbiota and the tumor immune microenvironment. Our previous clinical trial demonstrated that berberine (BBR) hydrochloride might reduce the recurrence and canceration of colorectal adenoma (CRA). The present study aimed to further explore the mechanism of BBR in preventing colorectal cancer (CRC).@*METHODS@#We performed metagenomics sequencing on fecal specimens obtained from the BBR intervention trial, and the differential bacteria before and after medication were validated using quantitative polymerase chain reaction. We further performed ApcMin/+ animal intervention tests, RNA sequencing, flow cytometry, immunohistochemistry, and enzyme-linked immunosorbent assays.@*RESULTS@#The abundance of fecal Veillonella parvula ( V . parvula ) decreased significantly after BBR administration ( P = 0.0016) and increased through the development from CRA to CRC. Patients with CRC with a higher V. parvula abundance had worse tumor staging and a higher lymph node metastasis rate. The intestinal immune pathway of Immunoglobulin A production was activated, and the expression of TNFSF13B (Tumor necrosis factor superfamily 13b, encoding B lymphocyte stimulator [BLyS]), the representative gene of this pathway, and the genes encoding its receptors (interleukin-10 and transforming growth factor beta) were significantly upregulated. Animal experiments revealed that V. parvula promoted colorectal carcinogenesis and increased BLyS levels, while BBR reversed this effect.@*CONCLUSION@#BBR might inhibit V. parvula and further weaken the immunomodulatory effect of B cells induced by V. parvula , thereby blocking the development of colorectal tumors.@*TRIAL REGISTRAION@#ClinicalTrials.gov, No. NCT02226185.

Relationship between parental personality,mood disorders and family functions of the children with autism spectrum disorder / 中华实用儿科临床杂志

Objective The number of children diagnosed with autism spectrum disorder (ASD)has increased dramatically in the past years.Parents of children with ASD usually experience a variety of chronic and acute stressors that may decrease marital satisfaction and family functioning.The aim was to explore the characteristics of parental per-sonality,mood disorders and family functions of the Children with ASD and to explore the relevance factors in order to draw out methods to improve parental family functions.Methods A cross -sectional survey was conducted and 593 outpatients with ASD diagnosed in Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine form January 201 0 to January 201 4 were straight into the group,their parents were tested by Family Assessment Device (FAD),Zung Self -Rating Depression Scale(SDS),Zung Self -Rating Anxiety Scale(SAS)and Eysenck Personality Questionnaire(EPQ).SPSS 1 7.0 software was adopted to establish the database and statistical analysis.Results Ac-cording to FAD,parents of children with ASD had lower scores in problem solving[(2.1 0 ±0.37)scores]and roles [(2.09 ±0.27)scores](t =-6.669,P =0.000;t =-1 8.707,P =0.000)than the standard scores,while other di-mensions score were significantly higher than the standard scores in communicdtion[(2.25 ±0.35)scores],emotional reaction[(2.38 ±0.40)scores],emotional involvement[(2.36 ±0.37)scores],behavioral control[(2.31 ±0.27) scores]and general function[(2.1 2 ±0.38)scores],there were significant differences(t =3.1 35,1 1 .1 1 5,1 6.997, 37.1 1 6,8.064;P =0.002,0.000,0.000,0.000,0.000).For EPQ of parents,mother had obviously higher scores than father in psychoticism scale[(53.68 ±1 .36)scores vs (52.65 ±1 .1 7)scores,t =-1 3.841 ,P =0.000],and signifi-cantly lower scores in Lie scale[(52.27 ±0.79)scores vs (52.1 7 ±0.75)scores,t =2.449,P =0.01 4].Compared to fathers,mothers were coded as higher depression and anxiety scores(t =-6.276,-6.440,all P =0.000)and higher prevalence rate(χ2 =1 5.893,27.592,all P =0.000),which were statistically significant.According to the asso-ciation study of FAD and the others(especially in mood of parents),it was found that several dimensions showed obvious correlation.Conclusions Parents of children with ASD have family function damaged badly,except for prob-lem solving and roles.The parents showed different personality traits and mood disorders,particularly mothers′mood disorder problem was prominent.Parental family functioning were closely related to their personality traits and emotional disorders in various dimensionalities,which was worthy of attention.
