3超重与男性生殖能力研究进展:睡眠呼吸暂停,一个新领域显示文摘肥胖会对男性生殖产生负面影响,主要是因为肥胖与低睾酮水平和促性腺激素改变有关。男性肥胖已经被发现与男性生育力下降有关,但由于影响的性质和程度不同,肥胖与精子参数相关性的数据存在争议。一些新研究领域的出现,如遗传多态性和睡眠呼吸暂停,将有助于解释研究结果的差异性。已经发现睡眠紊乱与男性睾酮生成的变化和性腺功能低下有关,也可能与勃起功能障碍有关。睡眠紊乱与不育和精子参数的关系还有待研究。忠有性腺功能低下和不育的男性应该进行睡眠呼吸暂停症的筛查。对肥胖和睡眠呼吸暂停的治疗可以改善睾酮水平和勃起功能。Ahmad O Hammoud Douglas T Carrell Mark Gibson C Matthew Peterson A Wayne Meikle 2012Asian Journal of Andrology2012,14,1:11
4Notch signaling controls chondrocyte hypertrophy via indirect regulation of Sox9显示文摘RBPjk-dependent Notch signaling regulates both the onset of chondrocyte hypertrophy and the progression to terminal chondrocyte maturation during endochondral ossification. It has been suggested that Notch signaling can regulate Sox9 transcription, although how this occurs at the molecular level in chondrocytes and whether this transcriptional regulation mediates Notch control of chondrocyte hypertrophy and cartilage development is unknown or controversial. Here we have provided conclusive genetic evidence linking RBPjk-dependent Notch signaling to the regulation of Sox9 expression and chondrocyte hypertrophy by examining tissuespecific Rbpjk mutant(Prx1Cre;Rbpjkf/f), Rbpjk mutant/Sox9 haploinsufficient(Prx1Cre;Rbpjkf/f;Sox9f/1),and control embryos for alterations in SOX9 expression and chondrocyte hypertrophy during cartilage development. These studies demonstrate that Notch signaling regulates the onset of chondrocyte maturation in a SOX9-dependent manner, while Notch-mediated regulation of terminal chondrocyte maturation likely functions independently of SOX9. Furthermore, our in vitro molecular analyses of the Sox9 promoter and Notch-mediated regulation of Sox9 gene expression in chondrogenic cells identified the ability of Notch to induce Sox9 expression directly in the acute setting, but suppresses Sox9 transcription with prolonged Notch signaling that requires protein synthesis of secondary effectors.Anat Kohn Timothy P Rutkowski Zhaoyang Liu Anthony J Mirando Michael J Zuscik Regis J O'Keefe Matthew J Hilton 2015Bone Research2015,3,3:8

6Epistaxis in end stage liver disease masquerading as severe upper gastrointestinal hemorrhage显示文摘AIM:To describe the prevalence,diagnosis,treatment,and outcomes of end stage liver disease(ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage(UGIH).METHODS:This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011.RESULTS:A total of 1249 patients were registered for severe UGIH in the data basis,461(36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen(75%) subjects required posterior nasal packing and 2(10%) embolization in addition to correction of coagulopathy. Five(25%) patients died in the hospital,12(60%) received orthotopic liver transplantation(OLT),and 3(15%) were discharged without OLT. The mortality rate was 63% in patients without OLT.CONCLUSION:Severe epistaxis in patients with ESLD is(1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH;and(2) associated with a high mortality rate in patients not receiving OLT.Marine Camus Dennis M Jensen Jason D Matthews Gordon V Ohning Thomas O Kovacs Rome Jutabha Kevin A Ghassemi Gustavo A Machicado Gareth S Dulai 2014World Journal of Gastroenterology2014,20,38:3

10Bleeding risk with clopidogrel and percutaneous endoscopic gastrostomy显示文摘AIM To compare bleeding within 48 h in patients undergoing percutaneous endoscopic gastrostomy(PEG) with or without clopidogrel.METHODS After institutional review board approval, a retrospective study involving a single center was conducted on adult patients having PEG(1/08-1/14). Patients were divided into two groups: Clopidogrel group consisting of those patients taking clopidogrel within 5 d of PEG and the non-clopidogrel group including those patients not taking clopidogrel within 5 d of the PEG.RESULTS Three hundred and nineteen PEG patients were found. One hundred and sixty-eight males and 151 females with mean body mass index 28.47 ± 9.75 kg/m2 and mean age 65.03 ± 16.11 years were identified. Thirtythree patients were on clopidogrel prior to PEG with 286 patients not on clopidogrel. No patients in either group developed hematochezia, melena, or hematemesiswithin 48 h of percutaneous endoscopic gastrostomy(PEG). No statistical differences were observed between the two groups with 48 h for hemoglobin decrease of > 2 g/dL(2 vs 5 patients; P = 0.16), blood transfusions(2 vs 7 patients; P = 0.24), and repeat endoscopy for possible gastrointestinal bleeding(no patients in either group). CONCLUSION Based on the results, no significant post-procedure bleeding was observed in patients undergoing PEG with recent use of clopidogrel.Umair Sohail Chela Harleen Amin O Mahdi Murtaza Arif Douglas L Nguyen Matthew L Bechtold 2016World Journal of Gastrointestinal Endoscopy2016,8,16:2

13【特刊综述】雄激素对骨骼肌的作用:对乏力的发展和治疗的意义显示文摘雄激素对骨骼肌合成有明显影响,随着年龄增大,雄激素的下降常伴随肌量和肌力的下降。这种肌量和肌功能的下降,被称为少肌症或肌体老化,是老年人体质弱化(男性化减退)进展的关键事项。也是导致快速机能衰退及其不良后果的关键。雄激素水平下降对老年男性体质弱化(男性化减退)的潜在影响和对躯体功能的促进治疗作用无疑已经引起了相当的关注。本综述概述了近期关于肌肉老化、少肌症、老年体质弱化的概念、定义,并评估了关于雄激素和老年体质弱化的研究进展。近期源于观测性和介入性研究的证据强烈支持雄激素对老年男性肌量的作用,但雄激素对肌力和特有的躯体功能的效用并不明确。研究显示,雄激素治疗在老年男性中通常有良好的耐受性,而近期的研究则关注于雄激素的高剂量治疗和对于心血管风险较高人群的治疗。雄激素受体调节剂(SARMs)的初期试验研究显示传统雄激素治疗对于老年患者在肌量和肌功能方面有相同的效用。将来的重要研究方向包括利用这类雄激素治疗并结合适用于不同老年患者群体促进躯体功能的运动训练,同时将更多地关注近期关于激素水平、身体成分及躯体功能间关系的观测性(回顾性)研究。Matthew DL O'Connell Frederick CW Wu 2014Asian Journal of Andrology2014,16,2:2
