AIM:To elucidate the molecular mechanisms of lipoic acid (LA) on redox regulation and digestive function in intestine of C57BL/6 mice fed high fat diet (HFD).METHODS:C57BL/6 mice were randomly assigned to one of three groups (n=8). The control group consumed an ordinary diet. The other two experimental groups were fed with a high fat diet,high fat plus 0.1% LA. After 6 weeks,the activities of digestive enzymes were examined. In order to evaluate the antioxidant status of the mice,superoxide dismutase (SOD),malondialdehyde (MDA),total antioxidant capacity (TAC) and reactive oxygen species (ROS) in intestinal homogenate were measured. To investigate the molecular mechanisms underlying the effects of LA,the gene expression profiles in intestine were examined using the GeneChip microarray system.RESULTS:A depressed antioxidant defense system,accompanied by digestive and absorptive function impairment,was observed in HFD-fed mice. These changes were partially restored in the LA-treated group. DNA microarray analysis of intestine showed that LA ingestion up-regulated the expression of genes related to free-radical scavenger enzymes,digestive enzymes and transporters.CONCLUSION:Treatment with LA improves redox homeostasis and the function of intestine in mice fed HFD. The mechanism may involve preventing oxidative stress by scavenging ROS directly and increasing those of free-radical scavenger enzymes gene expression indirectly.

Objective To explore the influence of high fat diet on the intestinal gene expression profile in C57BL/6 mice. Method C57BL/6 mice were randomly assigned to two groups (n=8). The control group consumed an ordinary diet. The experimental group was fed with a high fat diet. All mice were sacrificed at the end of 6 w and the intestinal gene expressions were detected by oligonucleotide microarray analysis with Affymetrix GeneChip Mouse U430A consisting of 13 097 genes. Results Among the 13 097 genes obtained from gene expression profile analysis, there were 88 and 179 genes up -and down-regulated respectively, in mice fed with high fat diet compared with the control. The differentially expressed genes were mainly related to free radical oxidative stress, DNA repair, induction of apoptosis, transport, signal transduction and inflammation immune response. Conclusion High fat diet may widely modulate the expression of many genes in the intestine in mice.

Objective A cross-sectional survey was conducted to investigate difference in job-related satisfaction indexes among staff working at community health-care service centers ( CHSC ) employing appropriate techniques on a trial basis between east and west areas of China. Methods In total, 339 staff members working at CHSC employing appropriate techniques on a trial basis, including good practice of community medical records management for hypertension , good practice of community case management for type 2 diabetes , good practice of community case management for tuberculosis , etc. , were recruited for questionnaire survey from Tianjin, Jinan and Shenzhen of east China and Chengdu and Chongqing in westChina by cluster sampling. Their demographic information, training for appropriate techniques and job-related satisfaction were collected. Results There was a significant difference in proportion of CHSC staff who receiving training for tuberculosis management launched by local government between west and east areas (34. 8% vs. 41. 4% , P <0. 05). There also was significant difference in satisfaction with the support from the superior sectors of government between west and east areas ( 59. 6% vs. 52. 0% , P = 0. 022 ) . Satisfaction towards income ranked the highest, and that towards work environment the lowest among the staff either in west or east areas. Conclusions Proportion of CHSC staff receiving training for tuberculosis and satisfaction with the support from superior sectors of government vary with communities in east and west areas employing appropriate techniques on a trial basis, and work condition of CHSC should be improved further.

Objective:To summarize the diagnosis features of the prenatal genetic diagnosis of fetal renal cystic disease and to explore the clinical feasibility and significance of prenatal genetic diagnosis of congenital cystic nephrosis.Methods:A total of 25 fetuses with congenital renal cystic disease were examined via invasive prenatal diagnosis in Henan Provincial People's Hospital from June 2017 to September 2019. Amniotic fluid samples were extracted by amniocentesis. Chromosomal microarray analysis (CMA) were performed in 17 cases. In addition to CMA, the other 8 cases were analyzed by G-band karyotype. Whole exome sequencing (WES) was performed in 6 cases which got normal results by CMA and karyotype, and highly suspected as hereditary disease.Results:Of the 25 fetuses assessed, 4 cases (16.0%) pathogenic copy number variation (pCNV) were found, including 2 cases of 17q12 deletion, 1 case of 10p15.1p14 deletion and 1 case of 4q21.28q22.1 deletion(including PKD2 gene). There were 8 cases without chromosome abnormality by karyotype analysis. Six clinical WES analysis found NPHS1 gene c.1440+1 G>A and c.925G > T mutations were related to Finnish type congenital nephrotic syndrome in 1 case, PKD1 gene c.6878C>T mutation was related to autosomal dominant polycystic kidney disease (ADPKD) in 1 case, and there was no definitive mutation in 4 cases. Conclusions:CMA and next generation sequencing are powerful tools for accurate diagnosis, treatment and genetic counseling of fetal congenital renal cystic diseases. For congenital cystic nephropathy, genetic detection is helpful to clarify the etiology, and provide more exactly informations for prognosis evaluation, treatment and family genetic counseling.

Objective:To observe the clinical efficacy of filiform needle combined with fire needles for cervical radiculopathy(CR)due to wind-cold obstructing the meridians. Methods:A total of 60 patients with CR due to wind-cold obstructing the meridians were randomized into an observation group and a control group,with 30 cases in each group.The control group was treated with filiform needle treatment,and the observation group was treated with additional fire needle point-pricking treatment.The visual analog scale(VAS)and 20-point scale of CR developed by Yasuhisa TANAKA(YT-20)were scored before treatment and after 1,2,3,and 4 weeks of treatments.The tenderness threshold was measured.The local skin temperature was measured by an infrared thermal imager.A safety evaluation was performed after treatment. Results:After treatment,the VAS score in the observation group at each time point was lower than that in the control group(P<0.05).The YT-20 score,tenderness threshold,and local skin temperature in the observation group were all higher than those in the control group(P<0.05).The VAS score in the observation group at each time point after treatment was lower than that before treatment(P<0.05),and the YT-20 score,tenderness threshold,and local skin temperature at each time point were higher than those before treatment(P<0.05).After 3 and 4 weeks of treatments,the VAS score in the control group was lower than that before treatment(P<0.05),and the YT-20 score,tenderness threshold,and local skin temperature were higher than those before treatment(P<0.05).The group factor effects of VAS and YT-20 scores,tenderness threshold,and local skin temperature between the two groups were statistically significant(P<0.05).There was no significant difference in the time effect and the interaction effect between time and group(P>0.05). Conclusion:Filiform needle combined with fire needle or applied alone both can relieve neck pain in patients with CR due to wind-cold obstructing the meridians,and improve the temperature of the neck.The combination of filiform needle and fire needle works more quickly and has better efficacy.
