| 2 | PI 3-kinase pathway is responsible for antiapoptotic effects of atrial natriuretic peptide in rat liver transplantation显示文摘AIM:To investigate the in vivo effect of atrial natriureticpeptide(ANP)and its signaling pathway during ortho-topic rat liver transplantation.METHODS:Rats were infused with NaCl,ANP(5 μg/kg),wortmannin(WM,16 μg/kg),or a combination ofboth for 20 min.Livers were stored in UW solution(4°C)for 24 h,transplanted and reperfused.Apoptosis wasexamined by caspase-3 activity and TUNEL staining.Phosphorylation of Akt and Bad was visualized by West-ern blotting and phospho-Akt-localization by confocalmicroscopy.RESULTS:ANP-pretreatment decreased caspase-3activity and TUNEL-positive cells after cold ischemia,indicating antiapoptotic effects of ANP in vivo.The an-tiapoptotic signaling of ANP was most likely caused byphosphorylation of Akt and Bad,since pretreatment withPI 3-kinase inhibitor WM abrogated the ANP-inducedreduction of caspase-3 activity.Interestingly,analysis ofliver tissue by confocal microscopy showed translocationof phosphorylated Akt to the plasma membrane of hepa-tocytes evoked by ANP.CONCLUSION:ANP activates the PI-3-kinase pathwayin the liver in vivo leading to phosphorylation of Bad, an event triggering antiapoptotic signaling cascade inischemic liver. | Uwe Grutzner Melanie Keller Michael Bach Alexandra K Kiemer Herbert Meissner Manfred Bilzer Stefan Zahler Alexander L Gerbes Angelika M Vollmar | 2006 | World Journal of Gastroenterology2006，12，7： | 3 |
| 3 | Helicobacter pylori arginase mutant colonizes arginase Ⅱ knockout mice显示文摘AIM: To investigate the role of host and bacterial arginases in the colonization of mice by Helicobacter pylori (H.pylori).METHODS: H.pylori produces a very powerful urease that hydrolyzes urea to carbon dioxide and ammonium,which neutralizes acid.Urease is absolutely essential to H.pylori pathogenesis;therefore,the urea substrate must be in ample supply for urease to work efficiently.The urea substrate is most likely provided by arginase activity,which hydrolyzes L-arginine to L-ornithine and urea.Previous work has demonstrated that H.pylori arginase is surprisingly not required for colonization of wild-type mice.Hence,another in vivo source of the critical urea substrate must exist.We hypothesized that the urea source was provided by host arginase Ⅱ,since this enzyme is expressed in the stomach,and H.pylori has previously been shown to induce the expression of murine gastric arginase Ⅱ.To test this hypothesis,wild-type and arginase (rocF) mutant H.pylori strain SS1 were inoculated into arginase Ⅱ knockout mice.RESULTS: Surprisingly,both the wild-type and rocF mutant bacteria still colonized arginase Ⅱ knockout mice.Moreover,feeding arginase Ⅱ knockout mice the host arginase inhibitor S-(2-boronoethyl)L-cysteine (BEC),while inhibiting > 50% of the host arginase Ⅰ?activity in several tissues,did not block the ability of the rocF mutant H.pylori to colonize.In contrast,BEC poorly inhibited H.pylori arginase activity.CONCLUSION: The in vivo source for the essential urea utilized by H.pylori urease is neither bacterial arginase nor host arginase Ⅱ;instead,either residual host arginase Ⅰ?or agmatinase is probably responsible. | Songhee H Kim Melanie L Langford Jean-Luc Boucher Traci L Testerman David J McGee | 2011 | World Journal of Gastroenterology2011，17，28： | 3 |
| 4 | Age at diagnosis of type 2 diabetes and cardiovascular risk factor profile:A pooled analysis显示文摘BACKGROUND The diagnosis of type 2 diabetes(T2D)in younger adults,an increasingly common public health issue,is associated with a higher risk of cardiovascular complications and mortality,which may be due to a more adverse cardiovascular risk profile in individuals diagnosed at a younger age.AIM To investigate the association between age at diagnosis and the cardiovascular risk profile in adults with T2D.METHODS A pooled dataset was used,comprised of data from five previous studies of adults with T2D,including 1409 participants of whom 196 were diagnosed with T2D under the age of 40 years.Anthropometric and blood biomarker measurements included body weight,body mass index(BMI),waist circumference,body fat percentage,glycaemic control(HbA1c),lipid profile and blood pressure.Univariable and multivariable linear regression models,adjusted for diabetes duration,sex,ethnicity and smoking status,were used to investigate the association between age at diagnosis and each cardiovascular risk factor.RESULTS A higher proportion of participants diagnosed with T2D under the age of 40 were female,current smokers and treated with glucose-lowering medications,compared to participants diagnosed later in life.Participants diagnosed with T2D under the age of 40 also had higher body weight,BMI,waist circumference and body fat percentage,in addition to a more adverse lipid profile,compared to participants diagnosed at an older age.Modelling results showed that each one year reduction in age at diagnosis was significantly associated with 0.67 kg higher body weight[95%confidence interval(CI):0.52-0.82 kg],0.18 kg/m^(2) higher BMI(95%CI:0.10-0.25)and 0.32 cm higher waist circumference(95%CI:0.14-0.49),after adjustment for duration of diabetes and other confounders.Younger age at diagnosis was also significantly associated with higher HbA1c,total cholesterol,low-density lipoprotein cholesterol and triglycerides.CONCLUSION The diagnosis of T2D earlier in life is associated with a worse cardiovascular risk factor profile,compared to those diagnosed later in life. | Mary M Barker Francesco Zaccardi Emer M Brady Gaurav S Gulsin Andrew P Hall Joseph Henson Zin ZinHtike Kamlesh Khunti Gerald P McCann Emma L Redman David R Webb Emma G Wilmot Tom Yates Jian Yeo Melanie J Davies Jack A Sargeant | 2022 | World Journal of Diabetes2022，13，3： | 2 |

| 8 | 成人2型糖尿病不同筛查及预防策略成本效益分析显示文摘目的 比较针对2型糖尿病预防及治疗的4种筛查策略及随后予以的干预措施:(a)筛查2型糖尿病患者使其能接受早期检查及治疗,(b)筛查2型糖尿病和糖耐量受损患者,对糖耐量受损的人群予以生活方式干预以延缓或预防糖尿病的发生,(c)同(b)但予以药物干预措施,(d)不筛查。
设计 成本效益决策分析建立在对概率的发展和评估基础上,是从筛查到死亡的综合性经济决策分析模型。
研究对象 一组假设人群,筛查时年龄45岁,高于平均糖尿病风险水平。
数据来源 电子书目数据库收录的已发表的临床试验和流行病学研究;补充数据分别来自英国和威尔士健康统计署、风险筛查(STAR)研究和ADDITION研究的Leicester部分。
方法 建立一种决策树/Markov混合模型,以模拟每一种筛查策略的长期效用,包括临床和成本效益终点。该模型假设水平跨度为50年时间,其成本效益折损率为3.5%。采用敏感度分析以验证模型假设及确定哪种模型数据输入对结果的影响最大。
结果 与不筛查策略比较,筛查2型糖尿病、筛查糖尿病和糖耐量受损并予以生活方式干预、筛查糖尿病和糖耐量受损并予以药物干预治疗3种策略,每获得一个质量调整生命年(QALY)估计所需成本分别为(每年成本效益贴现率为3.5%)14150英镑(17560欧元;27860美元)、6242英镑和7023英镑。在支付意愿阈值为20000英镑时,各主动筛查策略通过干预产生的成本效益概率分别为49%,93%和85%。
结论 对年龄45岁、高于平均风险水平的人群进行2型糖尿病和糖耐量受损的筛查,并对糖耐量受损人群予以适当的干预似乎具有很好的成本效益。单独筛查糖尿病而不对糖耐量受损人群予以干预的策略具有的成本效益仍不确定,需要进一步研究确定早期检测糖尿病的作用。 | Clare L Gillies Paul C Lambert Keith R Abrams Alex J Sutton Nicola J Cooper Ron T Hsu Melanie J Davies Kamlesh Khunti 张晓梅(译) 纪立农(校) | 2008 | 英国医学杂志中文版2008，11，5： | 1 |
