1Foveal avascular zone area and parafoveal vessel density measurements in different stages of diabetic retinopathy by optical coherence tomography angiography显示文摘AIM:To investigate foveal avascular zone(FAZ) and parafoveal vessel densities(PRVD) by means of optical coherence tomography angiography(OCTA) in diabetic patients with or without diabetic retinopathy(DR) and to assess the reproducibility of FAZ and PRVD measurements.METHODS:Sixty diabetic patients(60 eyes) with different stage of DR(graded according to the International Clinical Severity Scale for DR) and 20 healthy subjects underwent FAZ area and PRVD measurements using OCTA by two experienced examiners.FAZ area in all patients was also assessed using fluorescein angiography(FA).RESULTS:In subject with proliferative DR and with moderate-severe non proliferative DR,FAZ area was significantly increased compared to healthy controls(P=0.025 and P=0.050 respectively measured with OCTA and P=0.025 and P=0.048 respectively measured with FA).OCTA showed significantly less inter-observer variability compared to FA.Concordance correlation coefficient(CCC) for FAZ area measurements was 0.829(95%CI:0.736-0.891) P<0.001 with FA and 1.000(95%CI:0.999-1.000) P<0.001 with OCTA.CCC was 0.834(95%CI:0.746-0.893) P<0.001 and 0.890(95%CI:0.828-0.930) P<0.001 for parafoveal superficial and deep vessel density measurements,respectively.CONCLUSION:OCTA shows progressive increase of FAZ area and reduction of PRVD in both superficial and deep plexus at increasing DR severity.FAZ area and PRVD measurements using OCTA are highly reproducible.Rodolfo Mastropasqua Lisa Toto Alessandra Mastropasqua Raffaella Aloia Chiara De Nicola Peter A Mattei Guido Di Marzio Marta Di Nicola Luca Di Antonio 2017International Journal of Ophthalmology(English edition)2017,10,10:26
2冠状动脉内影像学临床应用专家共识(第一部分):对冠状动脉介入治疗的指导与优化显示文摘欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。Lorenz Raber Gary S Mintz Konstantinos C Koskinas Thomas W Johnson Niels R Holm Yoshinubo Onuma Maria D Radu Michael Joner Bo Yu Haibo Jia Nicolas Meneveau Jose M.de la Torre Hemandez Javier Escaned Jonathan Hill Francesco Prati Antonio Colombo Carlo di Mario Evelyn Regar Davide Capodanno William Wijns Robert A Byme Giulio Guagliumi 2019中华心血管病杂志2019,47,1:17

5从附睾到卵子:CRISP蛋白在哺乳动物受精过程中的作用显示文摘哺乳动物的受精过程涉及精卵结合的很多步骤,是一个非常复杂的过程,其分了机制亟待阐明。此篇综述主要论述了CRISP(富含半胱氨酸的分泌蛋白)作为模型分子在哺乳动物受精过程中的价值。大量的体外实验和基因敲出模型研究显示,附睾内的CRISP1以两种不同的亲和力结合于精子表面,参与精子获能、精子-透明带结合、精卵融合的调控。这些研究成果可以延伸至人类。我们住研究中发现,人类具有与啮齿类同源的CRISP(hCRISP1),同样参与受精过样。CRISP家族的其他成员(睾丸内CRISP2、附挈内CRISP3—4、射精时的CRISP3)也参与了精卵结合的过程,提示同源分子间的相互协同有助于受精的成功。另外,我们的研究显示,CRISP蛋白伴随精子穿越男性及女性生殖管道的全过程。我们推测CRISP不仅参与了受精过程,而且可能成为不育和避孕研究的新靶点。Vanina G Da Ros Mariana Weigel Munoz Maria A Battistone Nicolas G Brukman Guillermo Carvajal Ludmila Curci Matlas D Gomez-Elias Debora J Cohen Patricia S Cuasnicu 2015Asian Journal of Andrology2015,17,5:5

7Clinical outcomes of tricuspid valve repair accompanying left-sided heart disease显示文摘AIM To determine whether the need for additional tricuspid valve repair is an independent risk factor when surgery is required for a left-sided heart disease.METHODS One hundred and eighty patients(68 ± 12 years,79 males) underwent tricuspid annuoplasty.Cox proportionalhazards regression model for multivariate analysis was performed for variables found significant in univariate analyses.RESULTS Tricuspid regurgitation etiology was functional in 154 cases(86%),organic in 16 cases(9%),and mixed in10 cases(6%),respectively.Postoperative mortality at 30 days was 11.7%.Mean follow-up was 51.7 mo with survival at 5 years of 73.5%.Risk factors for mortality were acute endocarditis [hazard ratio(HR) = 9.22(95%CI:2.87-29.62),P < 0.001],ischemic heart disease requiring myocardial revascularization [HR = 2.79(1.26-6.20),P = 0.012],and aortic valve stenosis [HR = 2.6(1.15-5.85),P = 0.021].Significant predictive factors from univariate analyses were double-valve replacement combined with tricuspid annuloplasty [HR = 2.21(1.11-4.39),P = 0.003] and preoperatively impaired ejection fraction [HR = 1.98(1.04-3.92),P = 0.044].However,successful mitral valve repair showed a protective effect [HR = 0.32(0.10-0.98),P = 0.046].Additionally,in instances where tricuspid regurgitation required the need for concomitant tricuspid valve repair,mortality predictor scores such as Euroscore 2 could be shortened to a simple Euroscore-tricuspid comprised of only 7 inputs.The explanation may lie in the fact that significant tricuspid regurgitation following leftsided heart disease represents an independent risk factor encompassing several other factors such as pulmonary arterial hypertension and dyspnea.CONCLUSION Tricuspid annuloplasty should be used more often as a concomitant procedure in the presence of relevant tricuspid regurgitation,although it usually reveals an overly delayed correction of a left-sided heart disease.Kasra Azarnoush Ahmad S Nadeemy Bruno Pereira Massoud A Leesar Céline Lambert Alaa Azhari Vedat Eljezi Nicolas Dauphin Etienne Geoffroy Lionel Camilleri 2017World Journal of Cardiology2017,9,10:4
8Immunohistochemical expression of intrarenal renin angiotensin system components in response to tempol in rats fed a high salt diet显示文摘AIM To determine the effect of tempol in normal rats fed high salt on arterial pressure and the balance between antagonist components of the renal renin-angiotensin system.METHODS Sprague-Dawley rats were fed with 8% Na Cl highsalt(HS) or 0.4% Na Cl(normal-salt,NS) diet for 3 wk,with or without tempol(T)(1 mmol/L,administered in drinking water). Mean arterial pressure(MAP),glomerularfiltration rate(GFR),and urinary sodium excretion(UVNa) were measured. We evaluated angiotensin Ⅱ(Ang Ⅱ),angiotensin 1-7(Ang 1-7),angiotensin converting enzyme 2(ACE2),mas receptor(Mas R),angiotensin type 1 receptor(AT1R) and angiotensin type 2 receptor(AT2R) in renal tissues by immunohistochemistry.RESULTS The intake of high sodium produced a slight but significant increase in MAP and differentially regulated components of the renal renin-angiotensin system(RAS). This included an increase in Ang Ⅱ and AT1 R,and decrease in ACE-2 staining intensity using immunohistochemistry. Antioxidant supplementation with tempol increased natriuresis and GFR,prevented changes in blood pressure and reversed the imbalance of renal RAS components. This includes a decrease in Ang Ⅱ and AT1 R,as increase in AT2,ACE2,Ang(1-7) and Mas R staining intensity using immunohistochemistry. In addition,the natriuretic effects of tempol were observed in NS-T group,which showed an increased staining intensity of AT2,ACE2,Ang(1-7) and Mas R.CONCLUSION These findings suggest that a high salt diet leads to changes in the homeostasis and balance between opposing components of the renal RAS in hypertension to favour an increase in Ang Ⅱ. Chronic antioxidant supplementation can modulate the balance between the natriuretic and antinatriuretic components of the renal RAS.Gabriel Cao Silvana Lorena Della Penna Nicolas Martín Kouyoumdzian Marcelo Roberto Choi Susana Gorzalczany Belisario Enrique Fernández Jorge Eduardo Toblli María Inés Roson 2017World Journal of Nephrology2017,6,1:4

13Transanal total mesorectal excision:a valid option for rectal cancer?显示文摘Low anterior resection can be a challenging operation, especially in obese male patients and in particular after radiotherapy. Transanal total mesorectal excision(Ta TME) might offer technical advantages over laparoscopic or open approaches particularly for tumors in the distal third of the rectum. The aim of this article is to review the current experience with Ta TME. The limits and future developments are also explored. Although the experience with Ta TME is still limited, it might be a promising alternative to laparoscopic TME, especially for difficult cases where laparoscopy is too demanding. The preliminary data on complications and short-term oncological outcomes are good, but also emphasize the importance of careful patient selection. Finally, there is a need for large-scale trials focusing on long-term outcomes and oncological safety before widespread adoption can be recommended.Nicolas C Buchs Gary A Nicholson Frederic Ris Neil J Mortensen Roel Hompes 2015World Journal of Gastroenterology2015,21,41:3
