Objective To investigate the association of the gene polymorphism of endothelial nitric-oxide synthase(eNOS) with pregnancy induced hypertension(PIH). Methods Sixty-six gravidas with PIH and 91 normal pregnant women(control) in the third trimester were investigated. The G894T mutation at exon 7 of the endothelial nitric-oxide synthase gene was studied by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The frequencies of eNOS GG, GT and TT genotypes were 62.1%, 34.8% and 3.1% in PIH group and (79.1%,) 20.9% and 0.0% in control group, respectively (P0.05). Conclusions The variant (G-T) of 894 polymorphism site of eNOS is associated with the genesis of PIH, but not related to the severity of PIH. T allele may be a susceptible gene to PIH.

Objective To investigate the developmental feasibility of early human fetal testes (<3 months) using xenografting technique and to acquire an accessible donor derivation that is essential for studying human germ cell development. Methods Nine testes from 10-13 weeks aborted fetus were grafted under the back skin of 6 castrated nude mice. Grafts were collected at different time point according to the growth of the donor tissues and the health condition of the recipients. Morphological and histological analyses were performed for the observation of the development of grafted immature testicular tissues. Results The mass of grafts was increased from about 5-7mg to 84.1mg (the biggest). Six of 9 testes were to be in developing. Histological observations showed a significant expansion of seminiferous tubules from (44.26±3.14)μm to (77.69±7.47)μm. Cells dispersedly distributed in seminiferous cords at the time of grafting migrated towards the basal part of seminiferous epithelium. Some germ cells with spermatogonium-like characteristics located on the basement membrane. Sertoli cells were in stages from immature into matured with abundant cytoplasm which were orderly arranged around spermatogonia forming a niche-like structure. Conclusion Testes from early aborted human fetus grafted under the back skin of castrated nude mice showed further development and therefore could be used as an easier accessible donor tissues for the investigation of human spermatogenetic mechanism.

Objective To explore the effect of diabetic liaison nurses on controlling blood sugar levels in patients with hyperglycemia in department other than endocrinology. Methods Four hundred diabetic patients with high blood sugar were selected from January to December, 2014 in department other than endocrinology. They were divided randomly into 2 groups equally:the control group and the observation group. The control group received traditional nursing care, while blood sugar management was carried out by diabetic liaison nurse in the observation group. Result Pre-discharge sugar metabolism in the observation group was significantly better than that in the control group (P<0.05). Conclusion The diabetic liaison nurses in other departments than the endocrinology department can help control blood sugar levels in patients with hyperglycemiain.

Objective To explore the radiosensitivity of berberine on esophageal cancer cells under hypoxia condition.Methods MTT assay and clonogenic survival assay were used to evaluate the effect of berberine on proliferation inhibition and radiosensitivity of esophageal cancer cells,respectively.Immunofluorescence was employed to examine the expression of HIF-1.The change of cell cycle distribution and cell apoptosis was assayed by flow cytometry.The expression of HIF-1 was measured by Western blot.DNA damage was detected by γ-H2AX Foci counting.Results With a clear dose and time effect,berberine inhibited cell proliferation and enhanced cell radiosensitivity(t =3.69,P＜0.05)with a sensitizing enhancement ratio(SER)of 1.42.Berberine caused a dose-dependent decrease in HIF-1 protein expression and also significantly increased the cell apoptosis in ECA-109 population(t=4.74,P＜0.05).Compared with the radiation alone group,berberine enhanced X-ray induced DNA double chain breaks(DSB).Conclusions Berberine can increase the radiosensitivity of esophageal cell line ECA-109,which may be associated with decrease of HIF-1 expression and induction of apoptosis in ECA-109 cells.

AIM: To investigate the association of osteoprotegerin ( OPG) gene single nucleotide polymor-phisms (SNPs), 163A/G (rs3102735) and 245T/G (rs3134069), with susceptibility to rheumatoid arthritis (RA) in Chinese Han population .METHODS:A total of 205 patients with RA and 171 healthy control subjects were enrolled into this study.Genotyping was performed by polymerase chain reaction-based restriction fragment length polymorphism and subsequently confirmed by DNA sequencing .Odds ratio ( OR) and 95%confidence intervals ( CI) were calculated for the risk genotypes and alleles .RESULTS: OPG gene polymorphisms 163A/G and 245T/G were conformed to the Hardy-Weinberg equilibrium .The statistical differences in the genotypes of AA , AG and GG at 163A/G locus were found in RA and controls.The G allele was associated with an increased risk of RA , with OR of 1.219 (95%CI:1.066~2.339).No significant difference was observed between RA group and control group with respect to genotypic and allelic frequencies of OPG gene 245T/G (P>0.05).CONCLUSION:The OPG gene 163A/G SNP may be associated with RA susceptibility , and G allele may be the risk factor for developing RA .

Objective To analyze the malaria control measures and epidemic trend in Hubei Province from 1974 to 2015, so as to provide the evidence for malaria elimination path analysis. Methods The malaria control data in Hubei Province from 1974 to 2015 were collected and analyzed retrospectively by descriptive epidemiological methods. Results The epidemic pro?cess of malaria in Hubei Province was divided into four stages. From 1974 to 1979,it was high prevalence state of malaria,and the average annual incidence was 174.47/10 000. From 1980 to 1999,the main control strategies were to control the infection source and mosquitoes,and the average annual incidence was 17.30/10 000,significantly downward. From 2000 to 2009, through the surveillance of infection sources and controlling malaria outbreaks and strengthening the floating population manage?ment,the average annual incidence was 0.42/10 000. After 2010,followed by the elimination phase of malaria,the incidence continued to decline. In 2013,there was no local infection for the first time. The difference of average annual incidence among above?mentioned stages was statistically significant(χ2=1 254.36,P<0.05). Conclusions The malaria epidemic process in Hubei Provincial experienced the high epidemic stage,sharply drop stage,low incidence phase and the elimination phase. How?ever,the natural factors affecting malaria still exist. Therefore,strengthening the control of imported malaria and surveillance should be the main task in the process of eliminating malaria in the future.

Scr;and in this detection,Cys C had an obvious advantage to other items .Conclusions Cyc C is considered as one sensitive index of renal function impairment of infantile diarrhea sufferer;its sensitivity is advanced than Urea,Scr,and also is closely correlated with the state of diarrhea.

Objective To screen the specific antigen mimotopes of influenza A(H1N1)virus by phage display technology,in order to pave a way to develop novel influenza vaccine.Methods Using human convalescent serum of pandemic influenza A(H1N1)in 2009 as solid-phase selective molecule,an artificial synthesized phage randomly displaying cyclic 7-mer peptide was screened with three rounds of "absorption-elution-amplification" selection.At the end of the third round selection,32 clones were randomly chosen from the top-agar phage plaques and placed onto E.coli ER2378 in logarithmic growth phase.After culturing for 5 hours,the positive clones were identified by enzyme linked immunosorbent assay(ELISA),cross reaction test and competitive inhibition assay.The identified positive clones were analyzed by DNA sequencing.The decoded amino acids sequences,which displayed on the surface of phage,were aligned with the hemagglutinin(HA)gene of influenza virus by homology comparison for definition of the mimotopes of influenza A(H1N1)virus.Results After enriching the specific antibody-binding phages from phage displaying peptide library,12 positive clones were chosen from 32 randomly selected clones.DNA sequencing and homology comparison showed that one epitope PLHARLP was confirmed as mimotope of swine influenza A(H1N1)virus antigen,which was composed of the 52nd,53rd,59th,60th,61st,83rd and 271st amino acid.Conclusions Swine influenza A(H1N1)mimotope has been obtained by cyclic 7-mer peptide phage library screening.This result provides a basis for developing new influenza virus vaccine from virus antigen mimotopes.
