| 1 | Endoscopic management of postoperative bile leaks显示文摘BACKGROUND: Significant bile leak as an uncommon complication after biliary tract surgery may constitute a serious and difficult management problem. Surgical management of biliary fistulae is associated with high morbidity and mortality. Biliary endoscopic procedures have become the treatment of choice for management of biliary Gstulae. METHODS: Ninety patients presented with bile leaks after cholecystectomy ( open cholecystectomy in 45 patients, cholecystectomy with common bile duct exploration in 20 and laparoscopic cholecystectomy in 25). The presence of bile leaks was confirmed by ERCP and the appearance of bile in percutaneous drainage of abdominal collections. Of the 90 patients with postoperative bile leaks, 18 patients had complete transaction of the common bile duct by ERCP and were subjected to bilioenteric anastomosis. In the remaining patients after cholangiography and localization of the site of bile leaks. therapeutic procedures like sphinctero-tomy, biliary stenting and nasobiliary drainage ( NBD ) were performed. If residual stones were seen in the common bile duct, sphincterotomy was followed by stone extraction using dormia basket. Nasobiliary drain or stents of 7F size were placed according to the standard techniques. The NBD was removed when bile leak stopped and closure of the fistula confirmed cholangiographically. The stents were removed after an interval of 6-8 weeks. RESULTS: Bile leaks in 72 patients occurred in the cystic duct (38 patients), the common bile duct (30 ), and the right hepatic duct (4). Of the 72 patients with post-operative bile leak, 24 had associated retained common bile duct stones and 1 had ascaris in common bile duct. All the 72 patients were subjected to therapeutic procedures including sphincterotomy with stone extraction followed by biliary stenting (24 patients), removal of ascaris and biliary stenting (1), sphincterotomy with biliary stenting (18), sphincterotomy with NBD (12), biliary stenting alone (12), and NBD alone (5). Bile leaks stopped in all patients at a median interval of 3 days (range 3-16 days) after endoscopic in- terventions. No difference was observed in efficacy and in time for the treatment of bile leak by sphincterotomy with endoprosthesis or endoprosthesis alone in patients with bile leak after surgery. CONCLUSIONS: Post-cholecystectomy bile leaks occur most commonly in the cystic duct and associated common bile duct stones are found in one-third of cases. Endoscopic therapy is safe and effective in the management of bile leaks and fistulae after surgery. Sphincterotomy with endoprosthesis or endoprosthesis alone is equally effective in the management of postoperative bile leak. | Naresh Agarwal Barjesh Chander Sharma Sanjay Garg Rakesh Kumar Shiv K Sarin | 2006 | Hepatobiliary & Pancreatic Diseases International2006,5,2: | 33 |
| 2 | Novel insights into the pathophysiology of varicocele and its association with reactive oxygen species and sperm DNA fragmentation显示文摘精索静脉曲张与减少的男繁殖潜力被联系了。与在 biomolecular 技术的进展,更好理解涉及精索静脉曲张挑起的阴囊的损坏的机制是可能的。尽管机制充分还没被描述了,它是可能的是 multifactorial,当前的证据在联系精索静脉曲张的男 subfertility 的致病建议反应的氧种类(ROS ) 和结果的氧化压力(OS ) 的中央角色。过多的 ROS 与精子 DNA 破碎被联系,它可以调停与精索静脉曲张有关的差的精子功能和授精结果的临床的表明。ROS/OS 和 DNA 破碎测试有潜力与常规精液分析相比提供另外的诊断、预示的信息并且可以在单个病人指导治疗学的管理策略。 | Chak-Lam Cho Sandro C Esteves Ashok Agarwal | 2016 | Asian Journal of Andrology2016,18,2: | 30 |
| 3 | Relationship between acrosin activity of human spermatozoa and oxidative stress显示文摘Aim: To study the association between seminal oxidative stress and human sperm acrosin activity.Methods: It is a prospective study consisting of 30 infertile men and 12 fertile normozoospermic volunteers. A full history, clinical examination and scrotal ultrasound were done to exclude other related factors such as smoking and varicocele. Presence of white blood cells (WBCs) in semen samples was evaluated by peroxidase staining. Lipid peroxidation in spermatozoa was induced after incubating with ferrous sulphate (4mmol/L) and sodium ascorbate (20 mmol/L). Induced peroxidation of spermatozoa was assessed by determining the production of thiobarbituric acid reactive substances (TBARS). Acrosin activity was measured using the gelatinolysis technique. The halo diameters around the sperm heads and the percentages of spermatozoa showing halo formation were evaluated. An acrosin activity index was calculated by multiplying the halo diameter by the halo formation rate. Results: A significant difference was observed in acrosin activity parameters and TBARS levels between samples with WBCs (>1×10^6/mL of ejaculate) and those without. This difference was also noted between the normozoospermic and the oligoasthenoteratozoospermic semen samples. The TBARS production by spermatozoa had a significant negativecorrelation with the acrosin activity index (r=-0.89, P<0.001). Conclusion: The presence of oxidative stress in an individual with leukocytospermia and/or abnormal semen parameters is associated with impaired sperm function as measured by its acrosin activity.

| 4 | 氧化应激检测在男性不育临床中的应用显示文摘活性氧 (ROS)在低浓度发生可以调节正常精子功能 ,而高浓度ROS危害精子的存活力和功能。ROS产生过量与抗氧化系统损伤会发生氧化应激 (OS)。目前认为损伤OS促进了一系列男性生殖功能的病理学改变。ROS介导的精子质膜过氧化损伤 ,可以解释在高比例的不育病人中观察到的精子功能缺陷。ROS产生过多也会破坏精子核内DNA的完整性。DNA碱基对OS敏感 ,这些结构的过氧化能引起碱基修饰、DNA链断裂以及染色质交联。由过量ROS诱发的DNA损伤会加速生殖细胞凋亡过程 ,导致与男性不育相关的精子计数降低 ,以及可以解释近半个世纪以来所观察到的精液质量明显下降现象。近 10年来 ,克里夫兰临床基金会的研究组已经查明了男性不育中OS的关键作用 ;研究的主要目的是将这些重要的知识从实验室转向临床应用。我们设计的研究目标 :①理解精液中OS发生的精确机制 ;②建立准确评估OS状态的实验 ,并进行质控研究 ;③检测OS与精子核DNA损伤之间的相关性 ; | Ashok Agarwal Ramadan Abdou Saleh | 2002 | 中华男科学杂志2002,8,1: | 26 |
| 5 | Gestational diabetes mellitus: An update on the current international diagnostic criteria显示文摘The approach to screening and diagnosis of gestational diabetes mellitus(GDM) around the world is disorderly. The protocols for diagnosis vary not only in-between countries, but also within countries. Furthermore, in any country, this disparity occurs in-between its hospitals and often exists within a single hospital. There are many reasons for these differences. There is the lack of an international consensus among preeminent health organizations(e.g., American College of Gynecologists and World Health Organization). Often there is a disagreement between the country's national diabetes organization, its local health society and its regional obstetric organization with each one recommending a different option for approaching GDM. Sometimes the causes for following an alternate approach are very obvious, e.g., a resource strapped hospital is unable to follow the ivory-tower demanding recommendation of its obstetric organization. But more often than not, the rationale for following or not following a guideline, or following different guideline within the same geographic area is without any perceivable explanation. This review is an attempt to understand the problems afflicting the screening and diagnosis of GDM globally. It traces the major temporal changes in the diagnostic criteria of(1) some respected health organizations; and(2) a few selected countries. With an understanding of the reasons for this disparity, a way forward can be found to reach the ultimate goal: a single global guideline for GDM followed worldwide. | Mukesh M Agarwal | 2015 | World Journal of Diabetes2015,6,6: | 21 |

| 7 | 氧化磷酸化与糖酵解:精子以何种途径获取能量?显示文摘精子为高度特异性的细胞,提供精子重要功能的主要能源一一三磷酸腺苷(ATP)主要通过两种代谢途径形成,即糖酵解和氧化磷酸化(OXPHOS)。ATP除了在精子的头部和鞭毛的主段通过糖酵解的方式产生外,在线粒体主要通过OXPHOS的方式产生。然而,在精子成功受精的过程中主要以何种方式产生ATP具有很大的差异性。与糖酵解相比,线粒体呼吸被认为是一种更有效的ATP合成代谢过程。然而,研究表明ATP从线粒体到精子鞭毛末端的扩散电位不足以支持精子的运动,这表明糖酵解是精子尾部区域主要的获能方式。多项研究表明虽然糖酵解是鞭毛产生ATP的主要方式,但是,精子运动所需要的能量主要还是来自于线粒体的呼吸。有些研究表明当糖酵解受到抑制的时候,精子仍能维持其正常的运动和功能,虽然目前尚未明确这种运动是否能持续足够长的时间,是否能够达到有效受精。本文主要目的是对哺乳动物精子能量的代谢进行综述,分析人类精子在受精的过程中以何种ATP代谢途径作为主要的能量供应方式。 | Stefan S du Plessis Ashok Agarwal Gayatri Mohanty Michelle van der Linde | 2015 | Asian Journal of Andrology2015,17,2: | 19 |

| 10 | Acute renal dysfunction in liver diseases显示文摘Renal dysfunction is common in liver diseases,either as part of multiorgan involvement in acute illness or secondary to advanced liver disease.The presence of renal impairment in both groups is a poor prognostic indicator.Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction.Obstructive or post renal dysfunction only rarely complicates liver disease.Hepatorenal syndrome(HRS)is a unique form of renal failure associated with advanced liver disease or cirrhosis,and is characterized by functional renal impairment without significant changes in renal histology.Irrespective of the type of renal failure,renal hypoperfusion is the central pathogenetic mechanism,due either to reduced perfusion pressure or increased renal vascular resistance.Volume expansion,avoidance of precipitating factors and treatment of underlying liver disease constitute the mainstay of therapy to prevent and reverse renal impairment.Splanchnic vasoconstrictor agents,such as terlipressin,along with volume expansion,and early placement of transjugular intrahepatic portosystemic shunt(TIPS)may be effective in improving renal function in HRS.Continuous renal replacement therapy(CRRT)and molecular absorbent recirculating system(MARS)in selected patients may be life saving while awaiting liver transplantation. | Alex P Betrosian Banwari Agarwal Emmanuel E Douzinas | 2007 | World Journal of Gastroenterology2007,13,42: | 14 |
| 11 | Endoscopic management of acute cholangitis in elderly patients显示文摘AIM: To evaluate clinical presentation, etiology, compli-cations and response to treatment in elderly patients with acute cholangitis.METHODS: Demographics, etiology of biliary obstruc-tion, clinical features, complications and associated systemic diseases of 175 patients with acute cholangitis were recorded. Endoscopic biliary drainage was performed using nasobiliary drain or stent. The complications related to ERCP, success of biliary drainage, morbidity, mortality and length of hospital stay were evaluated. RESULTS: Of 175 patients, 52 aged ≥ 60 years (groupⅠ, age < 60 years; group Ⅱ, age ≥ 60 years) and 105 were men. Fever was present in 38 of 52 patients of group Ⅱ compared to 120 of 123 in groupⅠ. High fever (fever ≥ 38.0℃) was more common in groupⅠ(118/120 vs 18/38). Hypotension (5/123 vs 13/52), altered sensorium (3/123 vs 19/52), peritonism (22/123 vs 14/52), renal failure (5/123 vs 14/52) and associated comorbid diseases (4/123 vs 21/52) were more common in group Ⅱ. Biliopancreatic malignancy was a common cause of biliary obstruction in group Ⅱ (n = 34) and benign diseases in groupⅠ(n = 120). Indications for biliary drainage were any one of the following either singly or in combination: a fever of ≥ 38.0℃ (n = 136), hypotension (n = 18), peritonism (n = 36), altered sensorium (n = 22), and failure to improve within 72 h of conservative management (n = 22). High grade fever was more common indication of biliary drainage in groupⅠand hypotension, altered sensorium, peritonism and failure to improve within 72 h of conservative management were more common indications in group Ⅱ. Endoscopic biliary drainage was achieved in 172 patients (nasobiliary drain: 56 groupⅠ, 24 group Ⅱ, stent: 64 groupⅠ, 28 group Ⅱ) without any significant age related difference in the success rate. Abdominalpain, fever, jaundice, hypotension, altered sensorium, peritonism and renal failure improved after median time of 5 d in 120 patients in groupⅠ(2-15 d) compared to 10 d in 47 patients of group Ⅱ (3-20 d). Normalization of leucocyte count was seen after a median time of 7 d (3-20 d) in 120 patients in groupⅠcompared to 15 d (5-26 d) in 47 patients in group Ⅱ. There were no ERCP related complications in either group. Five patients (carcinoma gallbladder n = 3, CBD stones n = 2) died in group Ⅱ and they had undergone biliary drainage after failure of response to conservative management for 72 h. There was a higher mortality in patients in group Ⅱ despite successful biliary drainage (0/120 vs 5 /52). Length of hospital stay was longer in group Ⅱ patients (16.4 ± 5.6, 7-30 d) than in groupⅠpatients (8.2 ± 2.4, 7-20 d).CONCLUSION: Elderly patients with acute cholangitis have a high incidence of severe cholangitis, concomitant medical illnesses, hypotension, altered sensorium, peritonism, renal failure and higher mortality even after successful biliary drainage. | Naresh Agarwal Barjesh Chander Sharma Shiv K Sarin | 2006 | World Journal of Gastroenterology2006,12,40: | 14 |

| 17 | Xanthogranulomatous cholecystitis:a premalignant condition?显示文摘BACKGROUND:Xanthogranulomatous cholecystitis(XGC)is an uncommon variant of chronic cholecystitis,characterized by marked thickening of the gallbladder wall and dense local adhesions.It often mimics a gallbladder carcinoma(GBC), and may coexist with GBC,leading to a diagnostic dilemma. Furthermore,the premalignant nature of this entity is not known.This study was undertaken to assess the p53,PCNA and beta-catenin expression in XGC in comparison to GBC and chronic inflammation. METHODS:Sections from paraffin-embedded blocks of surgically resected specimens of GBC(69 cases),XGC(65), chronic cholecystitis(18)and control gallbladder(10)were stained with the monoclonal antibodies to p53 and PCNA, and a polyclonal antibody to beta-catenin.p53 expression was scored as the percentage of nuclei stained.PCNA expression was scored as the product of the percentage of nuclei stained and the intensity of the staining(1-3).A cut-off value of 80 for this score was taken as a positive result. Beta-catenin expression was scored as type of expression-membranous,cytoplasmic or nuclear staining. RESULTS:p53 mutation was positive in 52%of GBC cases and 3%of XGC,but was not expressed in chronic cholecystitis and control gallbladders.p53 expression was lower in XGC than in GBC(P<0.0001).PCNA expression was seen in 65%of GBC cases and 11%of XGC,but not in chronic cholecystitis and control gallbladders.PCNA expression was higher in GBC than XGC(P=0.0001),but there was no significant difference between the XGC,chronic cholecystitis and control gallbladder groups.Beta-catenin expression was positive in the GBC,XGC, chronic cholecystitis and control gallbladder groups.But the expression pattern in XGC,chronic cholecystitis and control gallbladders was homogenously membranous,whereas in GBC the membranous expression pattern was altered to cytoplasmic and nuclear.CONCLUSION:The expression of p53,PCNA and beta-catenin in XGC was significantly different from GBC and similar to chronic cholecystitis,thus indicating the inflammatory nature of XGC and may not support a premalignant nature of the lesion. | Mila Ghosh Puja Sakhuja Anil K Agarwal | 2011 | Hepatobiliary & Pancreatic Diseases International2011,10,2: | 11 |
