Objective To evaluate of the glucose screening retest for gestational diabetes mellitus (GDM) during pregnancy. Methods A retrospective analysis of 714 pregnant women screened for GDM, between December 1,2001, and December 31,2002, was performed.The first glucose challenge test(GCT) was performed in 16～27 week and retested in 28～38 week.Diagnosis of GDM was based on the criteria of Dong.NDDG criteria was also discussed. Results (1) 1-hour glucose value of 50 g GCT ≥7.8 mmol/L was set as abnormal.The first 50 g GCT abnormal rate was 26.6%(190/714),and the retest abnormal rate was 35.2%(225/639).The mean age of pregnant women in 50 g GCT positive group was significantly higher than that in the negative group( P

Objective To analyze functioning and disability, unmet needs and the service for people with disabilities in Shenzhen, Guangdong, China. Methods Based on International Classification of Functioning, Disability and Health (ICF) and World Report on Disabil-ity, the theoretical framework had been constructed, and the unmet needs and service status for people with disabilities in Shenzhen in 2015 had been statistically analyzed. Results For the statistics of disability by categories, physical disability composed of 42.5%, speech disability composed of 1.5%;people with severe and extremely severe disabilities composed of 52.8%;Futian District composed of 19.7%, Yantian District composed of 2.2%;people aged 0 to 18 years composed of 17.4%, and people aged over 60 years (27.0%) were the larger group. For the unmet needs of people with disabilities, 25%needed rehabilitation therapy, 18.8%needed functional training, 23.2%needed assis-tive devices, and 32.9%had no need. For rehabilitation sevice in Shenzhen, 24.4%received rehabilitation therapy, 17.4%received function-al training, 20.4%received assistive devices, and 37.6%did not receive any service. For the barrier-free reconstruction, 4.6%needed bath-room reconstruction, and 0.7%needed internet access screen software. Conclusion The status of functioning and disability, unmet needs and service development of rehabilitation in Shenzhen had been analyzed. There was still a gap between unmet needs and services of rehabilita-tion. It recommended to construct precise services delivery based on unmet needs, improve the full coverage and quality of service of reha-bilitation.

Objective To construct erythromycin-overproducing mutants by tandemly expressing S-adenosylmethionine synthetase gene metK, Vitreoscilla hemoglobin gene vhbS and pleiotropic regulatory gene adpA in Saccharopolyspora eryth-raea.Methods Through PEG-mediated protoplast transformation , the integrative plasmid carrying metK, vhbS and adpA was respectively introduced into erythromycin-producing wild-type strain S.erythraea A226 and industrial strain WB .The engineered strains were generated by apramycin resistance screening and PCR identification .The erythromycin production was compared in original strains and their mutants by the inhibition test of Bacillus subtilis and HPLC analysis .Results and Conclusion Four A226-derived mutants A226-P1-P4 and three WB-derived mutants WB-P1-P3 were independently obtained.Compared with wild-type strain A226, the relative erythromycin titer of the four engineered strains A 226-P1-P4 was increased from 8%to 25%by scoring the growth-inhibition zones .Further HPLC analysis showed that the four mutants had increased erythromycin A yield by 64%-94%.Likewise, the relative erythromycin titer and erythromycin A yield of the three engineered strains WB-P1-P3 were enhanced by 6%-10%and 31%-62%, respectively, in comparison with the original strain WB.The results show the universality of enhancing erythromycin productionvia tandem expression of metK, vhbS and adpA in S.erythraea.

Objective To investigate the effects of activator protein-1(AP-1)decoy oligodeoxynucleotides (ODNs)on the myocardial fibrosis induced by angiotension Ⅱ(Ang Ⅱ)in vitro.Methods CFs of neonatal Spra- gue-Dawley(SD)rats were isolated by trypsin digestion method.CFs were co-cultured with 10~(-7)mol/L Ang Ⅱ in the presence of different concentration of activator protein-1(AP-1)decoy ODNs or mutational AP-1 decoy ODNs for 24 h.Collagen synthesis was assessed by hydroxyproline and the mRNA expression of collagen Ⅰ,collagen Ⅲ.Results The concentration of hydroxyproline increased significantly after treated by 10~(-7)mol/L Ang Ⅱ;decoy ODNs on the range of 10-200 nmol/L dose dependently decrease synthesis of collagen;Ang Ⅱ stimulates mRNA expression of collagen Ⅲ(1.04?0.07 vs 1.63?0.071,n=3,P

Objective To study the exact function of human gene 5 transactivated by pre-S1 protein of hepatitis B virus(PS1TP5)by investigating the gene expression of PS1TP5 in yeast cells. Methods Reverse transcription-polymerase chain reaction(RT-PCR)was performed to amplify the gene of PS1TP5 using the mRNA of HepG2 cells as template and the gene was cloned into pGEM-T vector.The gene of PS1TP5 was cut from pGEM-T-PS1TP5 vector and cloned into yeast expressive plasmid pGBKT7,then pGBKT7-PS1TP5 was transformed into yeast cell AH109.The yeast protein was isolated and analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) and Western hybridization.Results PS1TP5 gene was successfully amplified and identified by DNA sequencing.The digested fragment was cloned into pGBKT7 vector and transformed into yeast cell AH109.The results of SDS-PAGE and Western assay showed that the relative molecular weight of the expressed product was about 36 950,and PS1TP5 protein existed in yeast cells.Conclusion The findings suggest that PS1TP5 can be successfully expressed in yeast cell.

This paper was designed to observe the colocalization of 11beta-HSD1 and GR, and its significance in the rat hippocampus. Immunocytochemical dual-staining showed that not only 11beta-HSD1 but also GR immunoreactive substances were present in the cultured rat hippocampal neurons. Moreover, they were colocalized in the same hippocampal neuron. Synthetic glucocorticoid dexamethasone (DEX) up-regulated the protein expression and activity of 11beta-HSD1 in the cultured hippocampal neurons, as determined by Western blot and thin layer chromatography (TLC) respectively. The transfection of PC12 cells with the plasmid containing promoter sequence of 11beta-HSD1 gene and the reporter gene of CAT enzyme was conducted. DEX up-regulated the reporter gene expression in the system described above. The up-regulation of 11beta-HSD1 and reporter gene expression induced by DEX were both blocked by GR antagonist RU38486. Our study suggests that the colocalization of 11beta-HSD1 and GR in the hippocampus may be implicated in the up-regulation of 11beta-HSD1 expression by glucocorticoids combining to its promoter region, which in turn produces more biologically active glucocorticoids necessary for the binding of low affinity of GR.

Colorectal cancer (CRC) is a common malignancy burdening people globally, with increasing morbidity and mortality nowadays, due to the alternation in the diet type and lifestyle in modern society. Berberine, a type of benzylisoquinoline alkaloid, is widely present in numerous medicinal plants, particularly including Coptidis Rhizoma. Mounting evidence reveals that berberine possesses an array of pharmacological effects, such as anti-inflammation, anti-bacterium, anti-cancer, anti-diabetes mellitus and so on. In particular, berberine exhibits substantial inhibition on various types of cancers including CRC. Hereby, we sought to systematically review the suppressive effect of berberine on CRC through the diminishment of the proliferation and metastasis, induction of apoptosis, arrest of cell cycle, regulation of inflammatory reaction, the reverse of chemotherapeutic resistance and restoration of gut microbiota in CRC, so as to shed light on the in-depth mechanisms underlying the treatment of CRC with berberine in the clinical setting.
