Objective To investigate the prevalence of hepatitis B virus infection and its epidemiological characteristics among planned pregnancy couples in Chongqing.Methods A total of 10 712 planned pregnancy couples were selected by proportionally stratified multi-stage random sampling method during April and December 2013.A questionnaire survey was performed, and enzyme linked immunosorbent assay ( ELISA) was used for hepatitis B virus surface antigen ( HBsAg ) and hepatitis B surface antibody ( anti-HBs) detection.SAS 8.2 was adopted for data process.Chi-square test and test for linear trend were performed to compare the rates of HBsAg and anti-HBs among different populations.Results Among 21 424 individuals, 1 718 (8.02%) were HBsAg positive.The positive rate of HBsAg in husbands was 9.48%, which was significantly higher than that in wives (6.55%,χ2 =63.39, P<0.01).Anti-HBs was positive in 8 967 (41.85%) individuals, and the positive rates in husbands and wives were 42.39% and 41.32%respectively (χ2 =2.54, P>0.05).The positive rates of HBsAg and anti-HBs increased with the age (χ2 =2.98 and 9.83,P<0.01).The highest HBsAg positive rate and lowest anti-HBs positive rate were observed among individuals of southeast of Chongqing.The positive rates of HBsAg and anti-HBs varied in people with different occupation.The highest HBsAg and anti-HBs positive rates were found in private business owners (9.18%) and public employees (49.69%) , respectively;and the lowest HBsAg and anti-HBs positive rates were found in public employees (6.79%) and farmers (39.08%), respectively.As the education level increased, HBsAg positive rate was decreasing (χ2 =-3.33, P<0.01), and anti-HBs positive rate was increasing (χ2 =9.73, P<0.01).Conclusions The prevalence of HBV infection is still high among planned pregnancy couples in Chongqing in the year of 2013.Vaccination and the related treatments should be enforced in population with high risk of HIV infection.

Objective: To investigate the mortality and probability of premature death due to cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases and their trends among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020, so as to provide insights into the development of the chronic disease control strategy. Methods: The data regarding the mortality of cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020 were captured from the Zhejiang Provincial Chronic Diseases Surveillance Information Management System, and the crude mortality, standardized mortality by the sixth population census data in Zhejiang Province in 2010 and probability of premature death for these four chronic diseases were estimated. The trends in mortality and probability of premature death were analyzed in Hangzhou City from 2005 to 2020 using average annual percent change (AAPC). Results: A total of 6 436 deaths occurred due to cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020. The crude and standardized mortality rates were 183.33/105 and 152.88/105, which both appeared a tendency towards a decline from 2005 to 2020 (AAPC=-1.099% and -2.926%, both P<0.05), and the probability of premature death reduced from 10.40% in 2005 to 6.78% in 2020, which appeared a tendency towards a decline (AAPC=-2.827%, P<0.05). The probability of premature death due to malignant tumors, diabetes and cardio-cerebrovascular diseases all appeared a tendency towards a decline from 2005 to 2020 (AAPC=-2.681%, -6.571% and -2.286%, all P<0.05), while no significant changing trend was seen in the probability of premature death due to chronic respiratory diseases (AAPC=-4.263%, P>0.05). The probability of premature death for these four chronic diseases reduced from 13.55% in 2005 to 9.36% in 2020 among male residents (AAPC=-2.150%, P<0.05), and reduced from 7.18% in 2005 to 4.22% in 2020 among female residents (AAPC=-4.149%, P<0.05). Conclusions The mortality and probability of premature death due to chronic diseases appeared a tendency towards a decline in Xiacheng District, Hangzhou City from 2005 to 2020, and there was a significant decline in the probability of premature death for malignant tumors, cardio-cerebrovascular diseases and diabetes.

To construct a library of mouse single chain variable fragment (scFv) antibody against ofloxacin using phage display and recombinant antibody technique, specific anti-ofloxacin scFv was screened and 3D structure was homology modeling. Total RNA was extracted from hybridoma cell of ofloxacin mAb, and was used to amplify VH and VL gene by RT-PCR using random primer. Then they were linked by a DNA linker encoding (G1y4 Ser) 3 as VH-linker-VL sequence forming scFv by SOE(splicing by overlap extension) PCR. These fragments were inserted into phage T7 after double digestion and transformed with host bacteria BLT5403. 3 ×105 pfu / ml single chain antibody phage libraries were successfully constructed. Four positive phage scFv clones were screened by direct competitive ELISA after four times of enriched procedure in the order of adsorption-elution-amplificatio, 3D structure of specific scFv was homology modeling finally. This research lays a foundation for further massive expression of anti-ofloxacin scFv.

AIM: To study the effect of genistein on activation and proliferation of T cells,and explore the molecular mechanism of genistein. METHODS: Fluorescence conjugated monoclonal antibodies and flow cytometry were used to detect the express of CD69 and CD25 by activated T cells in vitro in response to Concanavalin (ConA )and Phorbol 12,13-dibutyrate(PDB) or T cell proliferation stained by CFSE in response to PDB / Ionomycin or ConA. RESULTS: Genistein inhibited the expression of CD69 and CD25 in activated T cells in response to Con A in a concentration-dependent manner and in response to PDB in a high concentration. Genistein inhibited proliferation of T cells in both groups in a concentration-dependent manner. CONCLUSION: Genistein inhibited activation and proliferation of T cells in vitro in response to polyclonal stimulus,and it may hold potential as a new immunosuppressant.

AIM: To study the effect of natural killer(NK)-cells on graft-versus-host disease(GVHD), graft rejection, engraftment and reconstituting of hematopoiesis in mouse allogeneic bone marrow transplantation. METHODS: Lethally irradiated BALB/c(H-2 d) mice were transplanted with C57/6j(H-2 b) bone marrow containing donor peripheral T cells and/or NK cells. Recipients CD 34 + cell counts and the expression of H-2K b+ cell were detected by flow cytometry, peripheral white blood cell(WBC) was detected by auto-cytometry, and the recipients survival rates, GVHD, engraftment and hematopoiesis recovery were then observed. RESULTS: In the group of transplanted with NK cells infusion, the incidence of GVHD was evidently lessened, the survival rates, WBC and CD 34 + cell counts and the expression of H-2K b+ cell were significantly high than that without NK cells infusion. CONCLUSION: In mouse allogeneic bone marrow transplantation, alloreactivity NK cells prevent GVHD, reduce graft rejection, and promote engraftment and reconstituting of hematopoiesis. [

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.
