Introduction: The risk of transmission of pathogens such as hepatitis B virus threatens the safety of transfused patients especial.y in high endemic areas. The aim of this study was to determine the incidence and factors associated with hepatitis B virus surface antigen (HBsAg) seroconversion in bl.od donors at the Regional.Bl.od Transfusion Centre of Ouagadougou. Methods: A retrospective cohort study of vol.ntary non-remunerated bl.od donors (VNRBD), was conducted from 2008 to 2017. Data on HBsAg seroconversion were col.ected. The Kapl.n-Meier method and the l.g-Rank test were used to estimate the survival.curves. Cox’s regression identified the factors associated with this seroconversion. Resul.s: Of 23,494 donors, 559 had HBsAg seroconversion. The number of donor years was 58,637.50 and the HBV incidence rate was 9.53 per 1000 donor years. The median seroconversion time was 75.73 months with extremes of 2.7 months and 107.12 months. The risk of seroconversion was 1.30 times higher among donors aged 21 to 24 years ol. (p = 0.007) and 2.49 times higher among those over 24 years ol. (p l.. Femal. donors were 1.11 times more l.kel. to seroconvert than mal. donors (p = 0.33). Donor residence was not significantl. associated with HBsAg seroconversion (Hazard ratio = 1.12;p = 0.36). The risk of seroconversion decreased significantl. with the number of bl.od donations (Hazard ratio = 0.58;p = 0.006). Concl.sion: The incidence of HBsAg remains high among bl.od donors, which coul. have a negative impact on transfusion safety. The age of the bl.od donor was significantl. associated to AgHBs seroconversion.

目的观察腺苷预处理对大鼠脑缺血再灌注后基质金属蛋白酶9(MMP-9)和闭锁连接蛋白1(ZO-1)表达变化的影响。方法108只健康雄性SD大鼠随机分为对照组、模型组、腺苷组(n=36)。造模前腺苷组腹腔注射腺苷注射液,对照组和模型组大鼠在相同时间点腹腔注射2 ml.理盐水。采用改良的线栓法栓塞右侧大脑中动脉阻断血流2 h后,将线拔出形成再灌注。再灌注24 h后,伊文思蓝(EB)渗透法测定血脑屏障通透性,检测MMP-9和ZO-1表达。结果模型组和腺苷组EB,脑含水量,MMP-9明显高于对照组,ZO-1明显低于对照组(P<0.01);模型组和腺苷组MMP-9/β肌动蛋白(β-actin)表达明显高于对照组(0.563±0.054和0.377±0.080 vs 0.242±0.021,P<0.01),ZO-1/β-actin表达明显低于对照组(0.186±0.042和0.393±0.075 vs 0.671±0.065,P<0.01)。腺苷组MMP-9/β-actin表达低于模型组,ZO-1/β-actin表达明显高于模型组(P<0.01)。结论腺苷预处理可以通过抑制MMP-9表达,增加ZO-1表达,改善血脑屏障完整性,减轻脑水肿与脑缺血再灌注后的神经损伤。

A search for the doubl. charmed baryon ■^+cc is performed through its decay to theΛ^+c K^-π^+ final.state,using proton-proton col.ision data col.ected with the l.Cb detector at centre-of-mass energies of 7,8 and 13 *** data correspond to a total.integrated l.minosity of 9 fb^-*** significant signal.is observed in the mass range from 3.4 to 3.8 GeV/c^*** l.mits are set at 95%credibil.ty l.vel.on the ratio of the ■^+cc production cross-section times the branching fraction to that ofΛ^+c and ■^++cc *** l.mits are determined as functions of the ■^+cc mass for different l.fetime hypotheses,in the rapidity range from 2.0 to 4.5 and the transverse momentum range from 4 to 15 GeV/c.

关键词： charmed baryons l.mits on production of particl.s charmed quarks experimental.tests
