1T2期胆囊癌肿瘤位置和手术范围对预后的影响:一项国际多中心研究显示文摘T2期胆囊癌根据肿瘤位置不同,进一步细分为T2a(腹膜侧)或T2b期(肝脏侧)。既往有研究认为对于腹膜侧(T2a)肿瘤,在不影响预后的情况下可避免肝脏切除,但是目前仍然缺乏可靠的证据。为了探讨肿瘤位置对T2期胆囊癌的预后价值并明确手术切除的适当范围,该研究分析了韩国、日本、智利和美国的14家医院中937例接受胆囊癌手术患者的临床及病理资料。Kwon W Kim H Han Y 杨发才(编译) 2020中华医学杂志2020,100,39:21
2Emergency cholecystectomy vs percutaneous cholecystostomy plus delayed cholecystectomy for patients with acute cholecystitis显示文摘BACKGROUND: In low-risk patients with acute cholecystitis who did not respond to nonoperative treatment, we prospectively compared treatment with emergency laparoscopic cholecystectomy or percutaneous transhepatic cholecystostomy followed by delayed cholecystectomy.METHODS: In 91 patients(American Society of Anesthesiologists class I or II) who had symptoms of acute cholecystitis ≥72 hours at hospital admission and who did not respond to nonoperative treatment(48 hours), 48 patients were treated with emergency laparoscopic cholecystectomy and 43 patients were treated with delayed cholecystectomy at ≥4 weeks after insertion of a percutaneous transhepatic cholecystostomy catheter. After initial treatment, the patients were followed up for 23 months on average(range 7-29).RESULT: Compared with the patients who had emergency laparoscopic cholecystectomy, the patients who were treated with percutaneous transhepatic cholecystostomy and delayed cholecystectomy had a lower frequency of conversion to open surgery [19(40%) vs 8(19%); P=0.029], a frequency of intraoperative bleeding ≥100 mL [16(33%) vs 4(9%); P=0.006],a mean postoperative hospital stay(5.3±3.3 vs 3.0±2.4 days;P=0.001), and a frequency of complications [17(35%) vs 4(9%);P=0.003].CONCLUSION: In patients with acute cholecystitis who presented to the hospital ≥72 hours after symptom onset and did not respond to nonoperative treatment for 48 hours, percutaneous transhepatic cholecystostomy with delayed laparoscopic cholecystectomy produced better outcomes and fewer complications than emergency laparoscopic cholecystectomy.Feza Y Karakayali Aydincan Akdur Mahir Kirnap Ali Harman Yahya Ekici G?han Moray 2014Hepatobiliary & Pancreatic Diseases International2014,13,3:20

5Difficult biliary cannulation: Historical perspective, practical updates, and guide for the endoscopist显示文摘Despite improvements in endoscopic technologies and accessories, development of advanced endoscopy fellowship programs, and advances in ancillary imaging techniques, biliary cannulation in endoscopic retrograde cholangiopancreatography(ERCP) can still be unsuccessful in up to 20% of patients, even in referral centers. Once cannulation has been deemed to be difficult, the risk of post-ERCP pancreatitis and technical failure inherently increases. A number of factors, including endoscopist experience and patient anatomy, have been associated with difficult biliary cannulation, but predicting a case of difficult cannulation a priori is often not possible. Numerous techniques such as pancreatic guidewire and stenting, early pre-cut, and rendezvous may be employed when standard approaches fail. Data regarding the rate of success and adverse events of these techniques have been variable, though most studies suggest that pancreatic duct stenting generally reduces the rate of post-ERCP pancreatitis in instances of difficult biliary cannulation. Here we provide a review on difficult biliary cannulation and discuss how the choice of which techniques to employ and how to best employ them should be individualized and take into account the skill of the endoscopist, the disorder being treated, the anatomy of the patient, and the available biomedical literature.Rani Berry James Y Han James H Tabibian 2019World Journal of Gastrointestinal Endoscopy2019,11,1:8
6Visceral hypersensitivity in inflammatory bowel diseases and irritable bowel syndrome: The role of proteases显示文摘Proteases, enzymes catalyzing the hydrolysis of peptide bonds, are present at high concentrations in the gastrointestinal tract. Besides their well-known role in the digestive process, they also function as signaling molecules through the activation of protease-activated receptors(PARs). Based on their chemical mechanism for catalysis, proteases can be classified into several classes: serine, cysteine, aspartic, metallo- and threonine proteases represent the mammalian protease families. In particular, the class of serine proteases will play a significant role in this review. In the last decades, proteases have been suggested to play a key role in the pathogenesis of visceral hypersensitivity, which is a major factor contributing to abdominal pain in patients with inflammatory bowel diseases and/or irritable bowel syndrome. So far, only a few preclinical animal studies have investigated the effect of protease inhibitors specifically on visceral sensitivity while their effect on inflammation is described in more detail. In our accompanying review we describe their effect on gastrointestinal permeability. On account of their promising results in the field of visceral hypersensitivity, further research is warranted. The aim of this review is to give an overview on the concept of visceral hypersensitivity as well as on the physiological and pathophysiological functions of proteases herein.Hannah Ceuleers Hanne Van Spaendonk Nikita Hanning Jelena Heirbaut Anne-Marie Lambeir Jurgen Joossens Koen Augustyns Joris G De Man Ingrid De Meester Benedicte Y De Winter 2016World Journal of Gastroenterology2016,22,47:7

84-1BB signaling activates glucose and fatty acid metabolism to enhance CD8^(+) T cell proliferation显示文摘4-1BB(CD137)is a strong enhancer of the proliferation of CD8^(+)T cells.Since these cells require increased production of energy and biomass to support their proliferation,we hypothesized that 4-1BB signaling activated glucose and fatty acid metabolism.We found that treatment with agonistic anti-4-1BB mAb promoted the proliferation of CD8^(+)T cells in vitro,increasing their size and granularity.Studies with a glycolysis inhibitor and a fatty acid oxidation inhibitor revealed that CD8^(+)T cell proliferation required both glucose and fatty acid metabolism.Anti-4-1BB treatment increased glucose transporter 1 expression and activated the liver kinase B1(LKB1)-AMP-activated protein kinase(AMPK)-acetyl-CoA carboxylase(ACC)signaling pathway,which may be responsible for activating the metabolism of glucose and fatty acids.We also examined whether blocking glucose or fatty acid metabolism affected cell cycle progression and the anti-apoptotic effect of 4-1BB signaling.The increase of anti-apoptotic factors and cyclins in response to anti-4-1BB treatment was completely prevented by treating CD8^(+)T cells with the fatty acid oxidation inhibitor,etomoxir,but not with the glycolysis inhibitor,2-deoxy-D-glucose.We conclude that anti-4-1BB treatment activates glucose and fatty acid metabolism thus supporting the increased demand for energy and biomass,and that fatty acid metabolism plays a crucial role in enhancing the cell cycle progression of anti-CD3-activated CD8^(+)T cells in vitro and the anti-apoptotic effects of 4-1BB signaling on these cells.Beom K Choi Do Y Lee Don G Lee Young H Kim Seon-Hee Kim Ho S Oh Chungyong Han Byoung S Kwon 2017Cellular & Molecular Immunology2017,14,9:6

18Quality control measures for lowering the seroconversion rate of hemodialysis patients with hepatitis B or C virus显示文摘BACKGROUND: Hemodialysis (HD) patients are at high risk of infection by hepatitis B virus (HBV) or hepatitis C virus (HCV). The present study was designed to determine the impact of quality control measures on the prevention of transmission of blood-borne viruses. METHODS: A total of 6182 adult maintenance HD patients from all HD units in Zhejiang Province were recruited on January 1, 2007. The baseline demographic and clinical characteristics were recorded and all patients were followed up until death or survival at 4 years later. The Quality Control Standards of Hemodialysis were gradually implemented in HD units. The HBV or HCV seroconversion rates of the recruited patients were calculated and compared every year during the observation period. RESULTS: The prevalence of HBV was 8.3% at the beginning of the study, and 6.6% for HCV. With the implementation of the HD quality control measures, the HBV seroconversion rate tended to decrease year by year (χ 2 =6.620, P=0.085), and the HCV seroconversion rate decreased significantly (χ 2 =10.41, P=0.015). Compared with the data in 2007, the HBV seroconversion rate (χ 2 =4.204, P=0.040, relative risk ratio 0.393, 95% CI 0.156-0.991) and the HCV seroconversion rate (χ 2 =7.373, P=0.007, relative risk ratio 0.386, 95% CI 0.189-0.787) decreased significantly in 2010. CONCLUSION: Quality control measures for HD decreased the seroconversion rates of HBV or HCV in HD patients, showing that updated quality control measures reduce the risk for transmission of blood-borne viruses in the HD population.Jing Yuan,Yi Yang, Fei Han, Ping Zhang, Xiao-Ying Du, Hua Jiang and Jiang-Hua Chen The Kidney Disease Center, First Affiliated Hospital, Zhejiang University School of Medicine (Yuan J, Yang Y, Han F, Zhang P, Du XY, Jiang H and Chen JH) and Hemodialysis Quality Control Center of Zhejiang Province (Yuan J, Zhang P, Du XY and Chen JH), Hangzhou 310003, China 2012Hepatobiliary & Pancreatic Diseases International2012,11,3:2
