| 1 | Circulating endothelial and progenitor cells:Evidence from acute and long-term exercise effects显示文摘Circulating bone-marrow-derived cells,named endothelial progenitor cells(EPCs),are capable of maintaining,generating,and replacing terminally differentiated cells within their own specific tissue as a consequence of physiological cell turnover or tissue damage due to injury.Endothelium maintenance and restoration of normal endothelial cell function is guaranteed by a complex physiological procedure in which EPCs play a significant role.Decreased number of peripheral blood EPCs has been associated with endothelial dysfunction and high cardiovascular risk.In this review,we initially report current knowledge with regard to the role of EPCs in healthy subjects and the clinical value of EPCs in different disease populations such as arterial hypertension,obstructive sleep-apnea syndrome,obesity,diabetes mellitus,peripheral arterial disease,coronary artery disease,pulmonary hypertension,and heart failure.Recent studies have introduced the novel concept that physical activity,either performed as a single exercise session or performed as part of an exercise training program,results in a significant increase of circulating EPCs.In the second part of this review we provide preliminary evidence from recent studies investigating the effects of acute and long-term exercise in healthy subjects and athletes as well as in disease populations. | Matina Koutroumpi Stavros Dimopoulos Katherini Psarra Theodoros Kyprianou Serafim Nanas | 2012 | World Journal of Cardiology2012，4，12： | 18 |
| 2 | Autoimmune pancreatitis versus pancreaticcancer: a comprehensive review withemphasis on differential diagnosis显示文摘BACKGROUND: Autoimmune pancreatitis (AIP) is a rare form of chronic pancreatitis with a discrete pathophysiology occasional diagnostic radiological findings, and characteristic histological features. Its etiology and pathogenesis are still under investigation, especially during the last decade Another aspect of interest is the attempt to establish specific criteria for the differential diagnosis between autoimmune pancreatitis and pancreatic cancer, entities that are frequently indistinguishable. DATA SOURCES: An extensive search of the PubMed database was performed with emphasis on articles about the differential diagnosis between autoimmune pancreatitis and pancreatic cancer up to the present. RESULTS: The most interesting outcome of recent research is the theory that autoimmune pancreatitis and its various extra-pancreatic manifestations represent a systemic fibro inflammatory process called IgG4-related systemic disease The diagnostic criteria proposed by the Japanese Pancreatic Society, the more expanded HISORt criteria, the new definitions of histological types, and the new guidelines of the International Association of Pancreatology help to establish the diagnosis of the disease types. CONCLUSION: The valuable help of the proposed criteria for the differential diagnosis between autoimmune pancreatitis and pancreatic cancer may lead to avoidance of pointless surgical treatments and increased patient morbidity. | Kyriakos Psarras Minas E Baltatzis Efstathios T Pavlidis Miltiadis A Lalountas Theodoros E Pavlidis Athanasios K Sakantamis | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，5： | 9 |

| 4 | Current surgical management of pancreatic endocrine tumor liver metastases显示文摘BACKGROUND: The management of metastatic disease in pancreatic endocrine tumors (PETs) demands a multidisciplinary approach and the cooperation of several medical specialties. The role of surgery is critical, even when a radical excision cannot always be achieved. DATA SOURCES: A PubMed search of relevant articles published up to February 2011 was performed to identify current information about PET liver metastases regarding diagnosis and management, with an emphasis on surgery. RESULTS: The early diagnosis of metastases and their accurate localization, most commonly in the liver, is very important. Surgical options include radical excision, and palliative excision to relieve symptoms in case of failure of medical treatment. The goal of the radical excision is to remove the primary tumor bulk and all liver metastases at the same time, but unfortunately it is not feasible in most cases. Palliative excisions include aggressive tumor debulking surgeries in well-differentiated carcinomas, trying to remove at least 90% of the tumor mass, combined with other additional destructive techniques such as hepatic artery embolization or chemoembolization to treat metastases or chemoembolization to relieve symptoms in cases of rapidly growing tumors. The combination of chemoembolization and systemic chemotherapy results in better response and survival rates. Other local destructive techniques include ethanol injection, cryotherapy and radiofrequency ablation. CONCLUSION: It seems that the current management of PETs can achieve important improvements, even in advanced cases. | Theodoros E Pavlidis Kyriakos Psarras Nikolaos G Symeonidis Efstathios T Pavlidis Athanasios K Sakantamis | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，3： | 5 |
| 5 | 欧盟可再生能源现状、未来发展与挑战显示文摘据估计,欧盟的可再生能源在欧盟内部总能耗中的份额将从1992年的5.3%提高到2020年的6.2%,到2030年这个比例仍将小于7%。而白皮书中规定的战略和行动计划将力图使欧盟的2010年可再生能源份额达到12%的目标。另外各国国内的可再生能源发展目标应该和欧盟目标中可再生能源电力份额从1997年的13.9%增加到2010年的22.1%的目标一致。发展可再生能源是欧盟能源政策的中心目标,因为可再生能源在欧盟的主要目标———减少二氧化碳的排放中扮演着一个重要的角色。而且它还将通过减少欧盟对进口能源的依赖增进能源供应安全性。从中长期来看,和常规能源相比,可再生能源在经济上具备竞争力。 | Kostantions D Patlitzianas Argyris G Kagiannas John Psarras 吴君棋 | 2003 | 能源工程2003，，5： | 4 |
| 6 | Effect of early propranolol administration on portal hypertensive gastropathy in cirrhotic rats显示文摘AIM:To investigate any protective effect of early propranolol administration in the development of portal hypertensive gastropathy in cirrhotic rats. METHODS:For the development of liver cirrhosis and portal hypertensive gastropathy,60 rats underwent ligation of the left adrenal vein and complete devascularization of the left renal vein,followed by phenobarbital and carbon tetrachloride(CCl4) administration.After two weeks of CCl4 administration, the rats were randomly separated into two groups.In group A,propranolol was continuously administered intragastrically throughout the study,whereas in group B normal saline(placebo)was administered instead. Hemodynamic studies and vascular morphometric analysis of gastric sections were performed after complete induction of cirrhosis. RESULTS:Vascular morphometric studies showed higher numbers of vessels in all mucosal layers in the control group.Statistical analysis revealed a significantly higher total vascular surface in the control group compared to the propranolol group,but with no statistically significant difference between the mean vascular surfaces between the groups.Our study clearly shows that the increased mucosal blood flow is manifested by a marked increase of vessel count. CONCLUSION:Early propranolol's administration in portal hypertensive cirrhotic rats seems to prevent intense gastric vascular congestion that characterizes portal hypertensive gastropathy. | Savas Rafailidis Charalampos Demertzidis Konstantinos Ballas Michail Alatsakis Nikolaos Symeonidis Theodoros Pavlidis Kyriakos Psarras Valentini Tzioufa-Asimakopoulou Athanassios Sakadamis | 2009 | World Journal of Gastroenterology2009，15，34： | 3 |
