Objective To observe the effects of electro-acupuncture ( EA ) on learning, memory and the morphology of hippocampal neural tissues in rats with a model of chronic cerebral ischemia.Methods One hundred and twenty male Sprague-Dawley rats were used. Chronic cerebral ischemia models were successfully established in 104 of them, and those rats were randomly divided into an EA group and a model group with 52 rats each. These were further subdivided into 1,2, 4 and 6 week subgroups with 13 rats in each. The EA group was given EA. The changes in spatial learning and memory ability were observed using a Morris water maze. The morphological changes in hippocampal nerve tissue were observed by HE staining.Results The escape latency in the EA group was significantly different from the model group at the 2nd, 4th and 6th week. The nerve cells in the dentate gyrus were more tightly and consistently lined-up and had rich layers, and the structures in the EA group were better than in the model group.Conclusions EA can improve spatial learning and memory and promote the repair of injury after cerebral ischemia.

Objective To investigate the clinical phenotype, genotype and ultrastructural features in a pedigree with autosomal recessive congenital ichthyosis. Methods Patients were examined for clinical manifestation. PCR was carried out to amplify all the 15 exons and adjacent splice sites of TGM1 gene followed by bidirectional sequencing. Skin samples were taken by biopsy from the back of the proband, fixed in 3% glu-taraldehyde for transmission electron microscopy. Results The proband presented an intermediate clinical phenotype between lamellar ichthyosis (LI) and non-bullous congenital ichthyosiform erythroderma (NCIE), while his brother manifested as a collodion baby. A C551T heterozygous mutation which located in the third exon of TGM1 gene and resulted in a substitution of arginine by cysteine at codon 143 (R143C), was detected in the proband, his brother and father. Meanwhile, another heterozygous C-to-T transition at position 759 causing a substitution of serine by phenylalanine at codon 212 (S212F), was noted in the proband, his brother and mother. Electron microscopy revealed not only features of ichthyosis congenital type Ⅲ but also those of ichthyosis congenital type Ⅱ in lesions of the proband. Conclusions The patients in this pedigree carry compound heterozygous mutations, i.e. R143C, a hot missense mutation, as well as a de novo mutation S212F. The proband, who harbors mutations in the TGM1 gene, shows electron microscopic features characteristic not only of ichthyosis congenital type Ⅱ but also of ichthyosis congenital type Ⅲ.

Objective To investigate the effect of resveratrol on miRNA-106b in Alzheimer′s disease ( AD ) animal model.Methods Fifty Kunming male mice were divided into five groups by completely randomized block sampling.The five groups included three dosage resveratrol groups , an AD model group and a control group.The AD models were established in one month prior to treatments. Subsequently, from the 31st day various doses of resveratrol were provided intragastricly for 60 days.Then the memory function was observed by the step-down test.Meanwhile, the varying expressions of APP , P62, ApoA1, miRNA-106b, ABCA1 were tested in each group to determine whether there is the binding site for miRNA-106b in APP 3′UTR sequence.Results Compared with the control group by step-down test, the memory function of the AD model group mice decreased in different degree , which in the drug treatment group was higher than that in the model group (P<0.05).Compared with the AD group, the expression of APP (1.131 ±0.035) in the drug treatment group was higher than that in the model group (0.652 ± 0.026), while the P62 (0.412 ±0.022) and ApoA1 (0.534 ±0.032) were lower than the model group ( all P<0.05 ).High and medium dose groups of resveratrol treatment reduced varying degrees of APP (0.733 ±0.018,0.929 ±0.019,F=177.733) levels, and increased P62(0.954 ±0.035,0.633 ±0.015, F=434.5 ) and ApoA1 ( 1.042 ±0.051, 0.824 ±0.034, F=286.582 ) levels ( all P<0.05 ).The expression of miRNA-106b (0.464 ±0.313) and ABCA1(0.293 ±0.042) in the model group was lower than that in the control group (miRNA-106b 1.064 ±0.032, F=238.159; ABCA1 0.781 ±0.027,F=341.61;both P<0.05).The miRNA-106b (0.843 ±0.034, 0.601 ±0.012) and ABCA1 (0.882 ± 0.025, 0.624 ±0.036) levels in the high, medium dose resveratrol treatment groups increased to different extent ( both P<0.05 ).After the drug treatment , luciferase reporter vector experiments showed that the APP 3′UTR sequence contains the binding site of miRNA-106b.Conclusions APP is one of the target genes of miRNA-106b.Resveratrol is capable of improving AD by enhancing the expression of miRNA-106b and down-regulating the target genes including APP , P62 and ApoA1.This provides a new theoretical basis for the clinical treatment of AD.
