OBJECTIVETo observe the effects of electroacupuncture (EA) with branch-foundation acupoint combination on the indices regarding pituitary-target gland axis in aging rats with yang deficiency, so as to explore its regulating mechanism on aging rats with yang deficiency.

METHODSForty healthy Sprague-Dawley female rats were randomly divided into a normal control group, a model group, an EA group and an EA control group, 10 rats in each group. Except the normal control group, the rats in the rest 3 groups were all treated with subcutaneous injection of D-galactose for 40 d, followed by intramuscular injection of hydrocortisone for 7 d to establish aging model with yang deficiency. After the successful establishment of model, the EA group was treated with EA at "Guanyuan" (CV 4), "Housanli" (ST 36) and "Baihui "(GV 20) while the EA control group was treated with EA at "Zhongji" (CV 3) "Yinlingquan" (SP 9) and "Yintang" (GV 29); the rats in the normal control group and model group were immobilized and fixed during the same time period. The treatments were given 6 times per week totally for 4 weeks. With radiation immunity analysis method, the 8 biological indices of pituitary-target gland axis, including thyroid-stimulating hormone (TSH), triiodothyronine (T3), tetraiodothyronine-4 (T4), adrenocorticotropic hormone (ACTH), corticosterone (CORT), estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were detected to observe the changes of their content.

RESULTSCompared with the normal control group, the serum level of TSH, T3, T4 and E2 were reduced in the model group (P<0.05, P< 0.01) while those of ACTH, CORT, FSH and LH were increased (P<0.05, P<0.01). Compared with the model group, the serum level of TSH, T3, T4 and E2 were increased in the EA group (P<0.05, P<0.01) while those of ACTH, CORT, FSH and LH were significantly reduced (P<0.05, P<0.01). Compared with the EA control group, the content of TSH was increased in the EA group without statistical significance (P>0.05), that of T3, T4 and E2 was increased (all P<0.05) and that of ACTH, CORT, FSH and LH was significantly reduced (all P<0.05).

CONCLUSIONThe electroacupuncture with branch-foundation acupoint combination has benign regulating effects on the key hormones of pituitary-target gland axis, which could effectively improve the dysfunction of pituitary-target gland axis that is caused by aging with yang deficiency; the efficacy of electroacupuncture with branch-foundation acupoint combination is superior to that of adjacent control acupoint combination.

OBJECTIVETo discuss the results and significance of the detection of the CFTR gene mutation in azoospermia patients with congenital unilateral absence of the vas deferens (CUAVD).

METHODSWe collected peripheral blood samples from 6 azoospermia patients with CUAVD for detection of the CFTR gene mutations and single nucleotide polymorphisms. We analyzed the genome sequences of the CFTR gene in comparison with the website of the UCSC Genome Browser on Human Dec. 2013 Assembly.

RESULTSMissense mutation of c. 592G > C in exon 6 was found in 1 of the 6 azoospermia patients with CUAVD and splicing mutation of c. 1210-12T[5] was observed in the noncoding region before exon 10 in 2 of the patients, both with the V470 haplotype in exon 11.

CONCLUSIONMutations of the CFTR gene can be detected in azoospermia patients with CUAVD and the detection of the CFTR gene mutation is necessary for these patients.

AIM:To investigate the effects of resveratrol ( Res) on the proliferation of ARPE-19 cells and to ex-plore the possible mechanisms.METHODS:After ARPE-19 cells were treated with Res at concentrations of 0, 50, 100, 150, 200 and 300 μmol/L for 24 h, 48 h and 72 h, the effects of Res on the proliferation of the cells were tested by CCK-8 assay.The ARPE-19 cells were treated with Res at concentrations of 0, 100, 150 and 200 μmol/L for 48 h.The effects of Res on the cell cycle and apoptosis were detected by flow cytometry with Annexin V-FITC/PI staining.The protein expression of proliferating cell nuclear antigen (PCNA) was detected by immunofluorescent assay.The mRNA expression of PCNA, P21 and P27 was determined by real-time PCR.RESULTS:The results of CCK-8 assay showed that Res inhibited the prolifera-tion of ARPE-19 cells in a time-and dose-dependent manner.The treatment with Res for 48 h resulted in an arrest of cell cycle at S phase without increasing cell apoptosis.Res inhibited the protein expression of PCNA in ARPE-19 cells.The re-sults of real-time PCR showed that Res increased the mRNA expression of P21 and P27, and decreased the mRNA expres-sion of PCNA.CONCLUSION: Res inhibits the proliferation of ARPE-19 cells and induces the cell cycle arrest at S phase.The mechanism may be related to up-regulation of P21 and P27, and down-regulation of PCNA.

BACKGROUND: Studies demonstrated that small intestinal submucosa (SIS) had no immunogenicity, which can not lead to rejection following transplantation, thus, this is an ideal skin substitutes for natural skin.OBJECTIVE: Basic fibroblast growth factor (bFGF) gene was transfected into bone marrow mesenchymal stem cells (BMSCs),and combined the cells with SIS to construct tissue-engineered skin.METHODS: BMSCs were obtained from Japanese big-earad rabbits, and in vitro cultured. Then the subculturad BMSCs were transfected by pCDNA3.1 plasmid, followed by incubation on swine SIS to construct the tissue-engineered skin. The growth of cells and phenotype of BMSCs were detected by flow cytometry. In addition, the result of transfecting BMSCs with pCDNA-bFGF vector was measured by Western blot, and the structure of tissue-engineered skin was observed.RESULTS AND CONCLUSION: After passaged, BMSCs were grown quickly with Iong-fusiform shape. The cells were positive expressed CD90 and CD44, but negative expressed CD45. bFGF had been transfected into BMSCs, and stable expressed. The transfected BMSCs grew well in SIS. By this method, tissue-engineered skin can be constructed in vitro.

The epidemic of rabies has rapidly increased and expanded in Yunnan province in recent years.In order to further analyze and understand the etiological reasons for the rapid expansion of rabies in Yunnan,a strain of rabies virus CYN1009D in Yunnan was isolated,and the complete genomic sequencing was carried out,and the bioimfomative analysis on genes/encoded proteins and phylogeny with reference to sequences in GenBank was performed.The complete genome of CYN1009D was 11923 nt in length and belonged to genotype I.The genes encoding different structural proteins were all conserved in their lengths,in comparison to other strains in China.The amino acid sequence was conserved at different antigen sites of NP,but the variation was detected at the secondary phosphorylation site of position 375; variations were also detected in the phosphorylation sites at positions 63-63 and 162 of PP; the sites playing important roles in virus synthesis,budding and viral morphology in MP were conserved; two glycosylation sites were detected at Asn37 and Asn319in GP,the neutralizing antigen sites in GP were conserved; the initial amino acid of LP (ML) was different from that of most of the strains in China (MM); the variations in G-L region in the intergenic region were significant.The phylogenic tree showed that CYN1009D has a closer genetic relationship to the strains in Southeast Asia,indicating that prevention and control on rabies in borderland areas should be reinforced meanwhile efforts are made to control rabies in China.

In this paper 3 different media (A,for yeast cultivation ; B, for laccase producing; D, for white rot fungi cultivation) were compared in enriching and screening decolorizing fungi culture using Reactive Black 5 (RB5) and Reactive Red (M-3BE) from the following three points: decolorization effects, abilities of producing enzymes and diversity of microbial community. 11 groups of fungi with obvious decolorization effects were obtained after enrichment for near one month. Among them, 6 groups came from medium D, the other two 3 groups from medium A and B, respectively. However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae (Monascus went), Erysiphaceae and Physodermataceae. Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae (Penicillium) were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.
