1面向21世纪的卒中新定义:美国心脏病学会和美国卒中学会声明显示文摘尽管脑血管病有着全球性影响且对其病理生理学的认识有了很多进步,但是'卒中'这一术语在临床实践、临床研究或公共卫生评估中的定义却不一致。传统的定义依据于临床,却没有考虑到科学技术的进步。美国心脏协会(AHA)和美国卒中协会(ASA)卒中分会组织了写作小组,为21世纪卒中新定义撰写专家共识性声明。中枢神经系统(CNS)梗死,指由缺血所导致的脑、脊髓或视网膜的细胞死亡,是基于持续性损害的神经病理学、神经影像学和(或)临床证据。CNS梗死表现为一个临床谱:缺血性卒中特指伴有明显症状的CNS梗死,而静息性梗死根据定义指未引起已知的症状的梗死。卒中也还包括脑出血和蛛网膜下腔出血。新定义的卒中结合了临床和组织学标准,可被用于实践、研究和公共卫生评估。俞羚 董荃 宋叶平 江静雯 李卉 刘亮贤 苏爱萍 李焰生 Sacco RL Kasner SE Broderick JP Caplan LR Connors JJ Culebras A Elkind MS George MG Hamdan AD Higashida RT Hoh BL Janis LS Kase CS Kleindorfer DO Lee JM Moseley ME Peterson ED Turan TN Valderrama AL Vinters HV 2013神经病学与神经康复学杂志2013,10,2:188
2破裂动脉瘤-栓塞或夹闭疗效相当(英文)显示文摘In the May 2009 issue of The Lancet Neurology,the 5-year follow-up results of the International Subarachnoid Aneurysm Trial(ISAT) were published.The authors concluded that,although the significant difference between coiling and neurosurgical clipping of ruptured intracranial aneurysms in terms of death and severe disability after 1 year has vanished(primary endpoint),coiling should still be favored over neurosurgical clipping because mortality rates significantly favored coiling.In this commentary,it is this particular conclusion that is challenged by combining data from previous ISAT publications with the current 5-year follow-up results.This modified intent-to-treat analysis clearly demonstrates that the significant advantage in terms of mortality in favor of the endovascularly treated patients is no longer present,with a hazard ratio of 0.80 in favor of endovascular treatment(95% confidence interval: 0.60-1.05;P =.10).Therefore,for everyday clinical practice and decision making,coiling and clipping are to be considered equivalent in the long term.Bakker NA Metzemaekers JD Groen RJ Mooij JJ Van Dijk JM 2010中华神经外科疾病研究杂志2010,9,3:41
3Experimental study of“Tong Xia”purgative method in ameliorating lung injury in acute necrotizing pancreatitis显示文摘AIM To investigate the role of tumor necrosisfactor(TNF)in lung injury during acutenecrotizing pancreatitis(ANP),and thetherapeutic effect of'Tong Xia'purgativemethod in minimizing the severity of lung injury.METHODS Fourteen canines were randomlydivided into 3 groups:the'Tong Xia'treatmentgroup(n = 5)using Dachengqitang;salinecontrol group(n = 5),and the sham operationgroup(n = 4).TNF activity in serum and inbronchoalveolar lavage fluid(BALF),the serumendotoxin levels were measured,and theseverity of lung injury evaluated.RESULTS Elevation of TNF activity was moreprominent in BALF than in serum.TNF activity inserum at 6 and 12 hours and in BALI:wassignificantly decreased in the'Tong Xia'treatment group than in the saline control one(q=21.11,q=12.07,q=9.03,respectively,P<0.01)and the lung injury was significantlyalleviated at 12 hours as compared with that inthe saline group,manifested as amelioration otthe lung wet/ dry weight ratio,decrease inprotein concentration and neutrophils count inBALF,and improvement of pulmonaryinflammatory changes.A positive correlationwas demonstrated between serum TNF activity and endotoxin level.CONCLUSION Hypersecretion of TNF is shownto be one of the major causes of lung injuryduring ANP;'Tong Xia'purgative method couldalleviate the degree of lung injury mediated byTNF.Xia Q Jiang JM Gong X Chen GY Li L Huang ZW 2000World Journal of Gastroenterology2000,6,1:31

8Acute liver failure is frequent during heat stroke显示文摘Acute liver failure (ALF) is relatively frequent during heat stroke (HS). This risk must be emphasized, because its incidence is higher than is usually thought. In a recent study by Weigand et al , two cases were reported in which liver failure was the leading symptom. We have confirmed their conclusion in a study of 25 cases of HS with ALF, compared with 25 other cases without ALF. Moreover, we observed that hypophosphatemia on admission could predict occurrence of ALF during HS. As for clinical and other biological parameters, phosphatemia should be monitored for at least 3 d in all cases of HS, even when it is thought to be mild.JM Garcin JA Bronstein S Cremades P Courbin F Cointet 2008World Journal of Gastroenterology2008,14,1:18

10Intraoperative cell salvage with autologous transfusion in liver transplantation显示文摘Liver transplant(LT) is the primary treatment for patients with end-stage liver disease. About 25000 LTs are performed annually in the world. The potential for intraoperative bleeding is quite variable. However, massive bleeding is common and requires blood transfusion. Allogeneic blood transfusion has an immunosuppressive effect and an impact on recipient survival, in addition to the risk of transmission of viral infections and transfusion errors, among others.Techniques to prevent excessive bleeding or to use autologous blood have been proposed to minimize the negative effects of allogeneic blood transfusion.Intraoperative reinfusion of autologous blood is possible through previous selfdonation or blood collected during the operation. However, LT does not normally allow autologous transfusion by prior self-donation. Hence, using autologous blood collected intraoperatively is the most feasible option. The use of intraoperative blood salvage autotransfusion(IBSA) minimizes the perioperative use of allogeneic blood, preventing negative transfusion effects without negatively impacting other clinical outcomes. The use of IBSA in patients with cancer is still a matter of debate due to the theoretical risk of reinfusion of tumor cells. However, studies have demonstrated the safety of IBSA in several surgical procedures, including LT for hepatocellular carcinoma. Considering the literature available to date, we can state that IBSA should be routinely used in LT, both in patients with cancer and in patients with benign diseases.Marcelo A Pinto Marcio F Chedid Leo Sekine Andre P Schmidt Rodrigo P Capra Carolina Prediger Jo?o E Prediger Tomaz JM Grezzana-Filho Cleber RP Kruel 2019World Journal of Gastrointestinal Surgery2019,11,1:16
11Molecular organic geochemical evidence for paleoenvironmental changes at 11.87—12.28 m in GS-1 sedimentary core,Gucheng Lake,East China显示文摘Organic lipids with different occurrence modes in a sedimentary core in a subtropicalfreshwater lake, Gucheng Lake, were sequentially extracted, separated and analyzed. Thedown-core variations of OEP index of alkanes, C18:2/C18:0 ratios of fatty acids, ratios of boundfatty acids to free fatty acids, thermo-maturity indices of hopanoid hydrocarbons and relativeconcentrations of sedimentary minerals revealed an evident increasing in allochthonous inputfrom rock detritus below 12.28 m in the sedimentary profile. The distribution pattern of tightly-bound β-hydroxy fatty acids indicated a difference in bacterial communities above and below theboundary, as well as the gammacerane index may assign a significant change in lake watersalinity. The evidence, in general, suggested that a significant paleoenvironmental change hadtaken place in ca. 9.6 kaBP on the regional basis.Zhang, G Sheng, GY Fu, JM Wang, SM 1999Chinese Science Bulletin1999,44,15:15

13Expression of perforin and granzyme B mRNA in judgement of immunosuppressive effect in rat liver transplantation显示文摘AIM To explore the expression of perform andgranzyme B genes mRNA to judge the effect ofimmunosuppression in acute rejection of livertransplantation.METHODS The expression of perform andgranzyme B genes mRNA was examined byreverse transcriptase-polymerase chain reaction(RT--PCR) in hamster to rat liver grafts under theimmunosuppression of cyclosporine or/andsplenectomy. Histological findings were studiedcomparatively.RESULTS Cyclosporine could obviouslydecrease the cellular infiltration, and completelyrepress the expression of mRNA for perform andgranzyme B, but could not change severehepatocyte necrosis and hemorrhage.SPlenectomy could significantly lightenhepatocyte necrosis, and completely eliminatehemorrhage, but not atfect the cellularinfiltration and the expression of perform andgranzyme B genes mRNA. Cyclosporine orsplenectomy alone could not prolong theSurvival time, however, their combination couldcompletely repress the rejection of liver grafts.The survival time of animals were significantlyprolonged (37.1 days ). The architecture ofhepatic lobules was preserved. There was slightcellular infiltration in the portal tracts and noexpression of perform and granzyme B genesmRNA could be seen in three weeks aftertransplantation.CONCLUSION Perform and granzyme B genesare valuable in judging the effect ofimmunosuppression in liver transplantation.Zhang SG Wu MC Tan JW Chen H Yang JM Qian QJ 1999World Journal of Gastroenterology1999,5,3:15

20Profile of hepatocyte apoptosis and bile lakes before and after bile duct decompression in severe obstructive jaundice patients显示文摘BACKGROUND:Excessive hepatocyte apoptosis and bile lakes in severe obstructive jaundice might impair liver functions.Although decompression of the bile duct has been reported to improve liver functions in animal studies,the mechanism of obstruction differs from that in humans.This study aimed to determine the profiles of hepatocyte apoptosis and bile lakes following bile duct decompression in patients with severe obstructive jaundice in the clinical setting.METHODS:We conducted a 'before and after study' on severe obstructive jaundice patients as a model of inhibition of the excessive process by bile duct decompression.Specimens of liver biopsies were taken before and after decompression of the bile duct and then stained by terminal deoxynucleotide transferase-mediated dUTP nick end-labeling(TUNEL) to identify hepatocyte apoptosis and by hematoxilin-eosin(HE) to identify bile lakes.All measurements were independently done by 2 observers.RESULTS:Twenty-one severe obstructive jaundice patients were included.In all patients,excessive hepatocyte apoptosis and bile lakes were apparent.After decompression,the hepatocyte apoptosis index decreased from 53.1(SD 105) to 11.7(SD 13.6)(P<0.05),and the bile lakes from 23.6(SD 14.8) to 10.9(SD 6.9)(P<0.05).CONCLUSION:Bile duct decompression improves hepatocyte apoptosis and bile lakes in cases of severe obstructive jaundice,similar to the findings in animal studies.Toar JM Lalisang Raden Sjamsuhidajat Nurjati C Siregar Akmal Taher 2010Hepatobiliary & Pancreatic Diseases International2010,9,5:9
