1Role of CD56-expressing immature biliary epithelial cells in biliary atresia显示文摘AIM: To analyze the clinical and pathological parameters and expression of the neural cell adhesion molecule(CD56) in patients with biliary atresia(BA).METHODS: Established clinical laboratory markers of hepatic function, including enzyme activity, protein synthesis, and bilirubin metabolism, were evaluated in patients with BA and compared with those in patients with choledochal cysts and neonatal hepatitis. Pathological changes in tissue morphology and fibrosis were examined by histological and tissue collagen staining. Immunohistochemical staining for the biliary epithelial cell markers CD56 and CK19 together with the Notch signaling related molecules Notch1 and Notch2 was performed in the context of alterations in the structure of intrahepatic biliary ducts.RESULTS: Differences in some clinical laboratoryparameters among the three diseases examined were observed, but they did not correlate with the pathological classification of fibrosis in BA. Immunohistochemical staining showed the presence of CD56-positive immature bile ducts in most patients(74.5%) with BA but not in patients with choledochal cysts or neonatal hepatitis. The number of CD56-expressing cells correlated with disease severity, with more positive cells present in the later stages of liver damage(81.8% vs 18.2%). Furthermore, bile plugs were mainly found in CD56-positive immature biliary ducts. Notch signaling was a key regulatory pathway in biliary duct formation and played a role in tissue fibrosis. Notch1 was co-expressed in CD56-positive cells, whereas Notch2 was found exclusively in blood vessels in the portal area of patients with BA. CONCLUSION: The maturation of biliary epithelial cells and the expression of Notch may play a role in the pathogenesis of BA.Rui-Zhong Zhang Jia-Kang Yu Jiao Peng Feng-Hua Wang Hai-Ying Liu Vincent CH Lui John M Nicholls Paul KH Tam Jonathan R Lamb Yan Chen Hui-Min Xia 2016World Journal of Gastroenterology2016,22,8:8
2美国苹果砧木育种历史、现状及其商业化砧木特性显示文摘综述美国苹果砧木的育种历史和现状,简介美国选育的苹果砧木特性,以期为我国苹果砧木的选育提供参考。美国从1968年开始苹果砧木育种,早期进行了资源的广泛评价和筛选,随后根据美国具体气候条件,将育种目标主要定为矮化和半矮化、抗火疫病、抗颈腐病、抗苹果绵蚜、抗重茬、早产丰产等,杂交后代进行深入、多层次的评价和筛选,最终成功选育出目前商业化和科研应用较广泛、已申请专利的14个苹果砧木品种,包括1个极矮化砧木、5个矮化砧木、8个半矮化砧木。主要特性:树体本身为小灌木,抗火疫病和苹果绵蚜,耐颈腐病和重茬,易繁殖;嫁接品种后致矮、早实丰产。可见,美国在矮化砧木选育之前的评价筛选及选育后的鉴定方面都具有系统的手段和方法,为苹果砧木选育的重要部分,可以作为我国苹果砧木育种的参考。王大江 Bus Vincent G M 王昆 高源 赵继荣 刘立军 李连文 朴继成 2018中国果树2018,0,6:7

4羟乙基淀粉溶液在复苏肠缺血-再灌注休克中的作用显示文摘目的 比较不同剂量羟乙基淀粉溶液 ( HES)对兔肠缺血再灌注损伤所致休克的复苏作用。方法 32只新西兰白兔随机分为 4组 :模型对照、乳酸林格液复苏组 ( L RS,2 0 m l· kg- 1 · h- 1 ) ,小剂量 HES复苏组 ( HES2 ml· kg- 1· h- 1 + L RS18m l· kg- 1· h- 1 ) ,大剂量 HES复苏组 ( HES2 0 ml· kg- 1· h- 1 )。采用肠系膜上动脉夹闭 6 0 m in后松夹行再灌注制备肠缺血再灌注休克模型 ,松夹再灌注时同步进行液体复苏。观测各时间点的血流动力学参数 (平均动脉压、心率、心排血量、肠系膜上动脉血流 ) ,并通过测定肠黏膜CO2 分压和动脉血 CO2 分压的差值 (动脉二氧化碳间隙 )、肠黏膜 p H值、动脉血乳酸浓度和氧输送等指标间接评估组织氧合情况。实验结束后累计动物死亡数。结果 HES能明显提高肠缺血再灌注休克时的血流动力学参数 ,与对照组和 L RS组比较差异均有显著性 ( P均 <0 .0 5 ) ;小剂量 HES比大剂量 HES改善血流动力学参数的作用更平稳 ( P均 <0 .0 5 ) ,且较其他 3组能明显降低血乳酸浓度和动脉二氧化碳间隙 ,减轻 p Hi的降低 ( P均 <0 .0 5 ) ;而大剂量 HES对上述参数的影响不明显 ,并可见动物口鼻出血及死亡 ;小剂量或大剂量HES与其他两组比较均能使氧输送回升 ( P均 <0 .0 5 )。涂自智 孙庆华 George Dimopoulos Suzana M Lobo Daniel de Backer 肖献忠 Jean-Louis Vincent 2004中国危重病急救医学2004,16,8:6
5金属诱导非晶硅横向晶化形成的多晶硅的生长研究显示文摘详细研究了金属诱导非晶硅横向晶化时间、温度对晶化生长的影响。结果显示 ,晶化生长速度受温度影响较大 ,其最大生长速度在 6 2 5℃附近。在较高的温度下 ,非晶自发成核和晶化 ,从而限制了金属诱导晶体生长速度。镍诱导源的长度和厚度也对晶体生长有影响 。秦明 Yuen C Y Poon Vincent M C 黄庆安 2001固体电子学研究与进展2001,21,3:4

7Safety and efficacy of ledipasvir/sofosbuvir on hepatitis C eradication in hepatitis C virus/human immunodeficiency virus co-infected patients显示文摘AIM To evaluate the safety and efficacy of ledipasvir/sofosbuvir on hepatitis C eradication in patients with hepatitis C virus(HCV)/human immunodeficiency virus(HIV) co-infection in an urban HIV clinic.METHODS A retrospective cohort study of 40 subjects co-infected with HIV-1 and HCV treated with the fixed-dose combination of ledipasvir and sofosbuvir for 12 wk from 2014 to 2016.All patients included were receiving antiretroviral therapy(ART) with HIV RNA values of 100 copies/m L or fewer regardless of baseline HCV RNA level.The primary end point was a sustained virologic response of HCV at 12 wk(SVR12) after the end of therapy.RESULTS Of the 40 patients enrolled,55% were black,22.5% had been previously treated for HCV,and 25% hadcirrhosis.The patients were on a wide range of ART.Overall,39 patients(97.5%) had a SVR 12 after the end of therapy,including rates of 97.1% in patients with HCV genotype 1 a and 100% in those with HCV genotype 1 b.One patient with HCV genotype 3 a was included and achieved SVR12.Rates of SVR12 were similar regardless of previous treatment or the presence of compensated cirrhosis.Only 1 patient experienced relapse at week 12 following treatment and deep sequencing didn't reveal any resistance associated mutation in the NS5A or NS5B region.Interestingly,7(17.5%) patients who were adherent to ART experienced HIV viral breakthrough which resolved after continuing the same ART regimen.Two(5%) patients experienced HIV-1 virologic rebound due to noncompliance with HIV therapy,which resolved after resuming the same ART regimen.No severe adverse events were observed and no patient discontinued treatment because of adverse events.The most common adverse events included headache(12.5%),fatigue(10%),and diarrhea(2.5%).CONCLUSION This retrospective study demonstrated the high rates of SVR12 of ledipasvir/sofosbuvir on HCV eradication in patients co-infected with HCV and HIV,regardless of HCV baseline levels,HCV treatment history or cirrhosis condition.The oral combination of ledipasvir/sofosbuvir represents a safe and well tolerated HCV treatment option that does not require modification for many of the common HIV ART.Occasional HIV virologic rebound occurred but later resolved without the need to change ART.Xiaoping He Lynne Hopkins George Everett Willie M Carter Cynthia SchroppDyce Khalid Abusaada Vincent Hsu 2017World Journal of Hepatology2017,9,30:2
