OBJECTIVETo evaluate the clinical therapeutic effect of electroacupuncture for treatment of catatonic schizophrenia.

METHODSEighty cases were randomly divided into an observation group and a control group, 40 cases in each group. The observation group was treated with electroacupuncture, Baihui (GV 20) and Taiyang (EXHN 5) were selected, once daily; the control group was treated with modified electric convulsive therapy (MECT), the treatment was given once every 2 days or 3 days, 14 to 21 days constituted one course in the two groups.

RESULTSThe markedly effective rate and total effective rate were 72.5% and 92.5% in the observation group, 77.5% and 97.5% in the control group, respectively, there was no significant difference between the two groups (both P>0.05).

CONCLUSIONThe therapeutic effect of electroacupuncture is similar to that of MECT.

OBJECTIVETo explore whether the vitamin D receptor gene (VDR) polymorphisms are associated with the outcomes of hepatitis B virus (HBV) infection in Chinese Han population.

METHODSPolymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the polymorphisms of Fok I locus in exon 2 and Taq I locus in exon 9 of VDR gene. One hundred and eighty-four chronic hepatitis B patients and 205 asymptomatic HBV carriers were recruited to make the comparison of frequencies of genotype and haplotype of the VDR gene between the patients and the carriers.

RESULTSThe univariate analysis showed a significant difference in Fok I polymorphism between chronic hepatitis B patients group and asymptomatic HBV carriers group. The FF genotype frequency in chronic hepatitis B patients group was 44.6%,higher than 31.7% in asymptomatic HBV carriers group (P<0.05). After adjusting the confounders by multiple logistic regression analysis, the result still showed a significant difference in Fok I site polymorphism between chronic hepatitis B patients group and asymptomatic HBV carriers group (OR=1.95, P<0.05). The FT haplotype frequency in chronic hepatitis B patients group was higher than that in asymptomatic HBV carriers group (OR=1.45, P<0.05). The fT haplotype frequency in chronic hepatitis B patients group was lower than that in asymptomatic HBV carriers group (OR=0.72, P<0.05).

CONCLUSIONVDR gene polymorphism may be an influence factor of genetic susceptibility to HBV infection.

ObjectiveTo investigate the effect of myosin heavy chain 7 gene-derived miRNA-208b-3p on the fibrotic phenotype of cardiac fibroblasts. MethodsmiRNA chip array was performed to detect the dysregulated miRNAs in the myocardium of diabetic db/db mice and db/m control mice. Neonatal mouse ventricular cardiomyocytes （NMVCs） and cardiac fibroblasts （CFs） were isolated from C57BL/6 mice and cultured. Real-time quantitative PCR （RT-qPCR） was conducted to determine the expression of miR-208b-3p in mouse CFs and NMVCs subjected to angiotensinⅡ（AngⅡ） and high glucose plus glucose oxidase （G/Go） treatment， respectively. Cell counting kit 8（CCk8） assay， flow cytometry and determination of fibrosis-related protein， including COL1A1， COL3A1and α-SMA， were performed in mCFs transfected with miR-208b-3p. Dual luciferase reporter assay was performed to confirm the interaction between miR-208b-3p and the 3'-UTR of metal response element binding transcription factor 2 （Mtf2） and progesterone receptor membrane component 1（Pgrmc1）， respectively. The expressions of Mtf2 and Pgrmc1 at the mRNA and protein levels in mCFs after miR-208b-3p mimic transfection were determined using RT-qPCR and Western blot assay， respectively. The small interfering RNA （siRNA） was used to inhibit Mtf2 and Pgrmc1 expression in mCFs， and the effects of Mtf2 siRNA， Pgrmc1 siRNA and miR-208b-3p on fibrosis-related protein expression in mCFs were investigated. ResultsResults of miRNA chip array and RT-qPCR assay showed that miR-208b-3p was up-regulated in the myocardium of the diabetic db/db mice. miR-208b precursor and the host gene of Myh7 were consistently increased in db/db mice. miR-208b-3p and Myh7 mRNA were expressed in mCFs and NMVCs， but the levels of miR-208b-3p and Myh7 mRNA in NMVCs were much higher than those in mCFs. miR-208b-3p was up-regulated in mCFs and NMVCs subjected to Ang Ⅱ and G/Go treatment， respectively. miR-208b-3p could significantly enhance fibrosis-related protein， including COL1A1， COL3A1 and α-SMA， in mCFs， without affecting the proliferation activity and cell cycle distribution of mCFs. Dual luciferase reporter assay revealed the interactions of miR-208b-3p with the 3'-UTR of Mtf2 and Pgrmc1. The results of RT-qPCR and Western blotting confirmed that miR-208b-3p inhibited Mtf2 and Pgrmc1 expression at the post- transcriptional level. Transfection with miR-208b-3p mimic， Mtf2 siRNA and Pgrmc1 siRNA could consistently enhance the fibrosis-related protein expression in the cardiac fibroblasts. ConclusionsmiR-208b-3p enhances fibrosis-related gene expression by targeting Mtf2 and Pgrmc1in mCFs.
