文摘Non selective beta blockers(NSBBs)are used in primary and secondary prophylaxis of portal hypertensionrelated bleeding in patients with cirrhosis.The efficacy of NSBBs treatment is predicted by hemodynamic response in term of reduction of the hepatic venouspressure gradient(HVPG)below 12 mm Hg or at least20%of the basal value.Nevertheless a relevant number of patients who do not achieve this HVPG reduction during NSBBs therapy do not bleed during follow up;this evidence suggests an additional non-hemodynamic advantage of NSBBs treatment to modify the natural history of cirrhosis.Recent studies have questioned the efficacy and safety of NSBBs in patients with advanced stage of liver disease characterized by refractory ascites and/or spontaneous bacterial peritonitis.These studies have suggested the existence of a defined and limited period to modify the natural history of cirrhosis by NSBBs:the"window hypothesis".According with this hypothesis,patients with cirrhosis benefit from the use of NSBBs from the appearance of varices up to the development of an advanced stage of cirrhosis.Indeed,in patients with refractory ascites and/or spontaneous bacterial peritonitis the hemodynamic effects of NSBBs may expose to a high risk of further complications such as renal insufficiency and/or death.Methodological concerns and contrasting results counterbalance the evidence produced up to now on this issue and are the main topic of this editorial.
文摘目的探讨可溶性E-钙黏蛋白(soluble E-cadherin,SE-CAD)、胸苷激酶-1(thymidine kinase 1,TK-1)在非小细胞肺癌(NSCLC)患者血清中的水平,并分析其与附睾蛋白4(HE4)、癌胚抗原(CEA)、细胞角蛋白19片段(CYFRA21-1)联合检测在NSCLC诊断中的临床应用价值。方法收集本院2016年1月至2018年1月期间初诊NSCLC患者86例、小细胞肺癌患者45例、同期良性疾病患者42例、同期初诊其他恶性肿瘤(除肺癌外)患者30例、健康受试者的血清标本40例,应用液态芯片技术对受试者血清标本进行CEA、CYFRA21-1水平检测,ELISA方法检测SE-CAD、TK-1、HE4。结果①非小细胞肺癌患者血清中SE-CAD水平明显高于良性对照组、正常对照组( P <0.05),差异具有统计学意义,但与小细胞肺癌组及其他恶性肿瘤组比较差异无统计学意义( P >0.05);②非小细胞肺癌组患者血清 TK1 与CYFRA21-1水平明显高于良性对照组、小细胞肺癌组、其他恶性肿瘤组和健康对照组,差异均有统计学意义(均 P <0.05)。③单项检测时,CYFRA21-1对非小细胞肺癌的诊断灵敏度最高,为87.2%,TK-1的诊断特异性最高。5种肿瘤标志物联合检测,灵敏度高达93.2%,特异性有所降低为85.7%。结论 SE-CAD、TK1 与CYFRA21-1均可作为鉴别良恶性肿瘤的检验指标,联合HE4、CEA、CYFRA21-1等指标对非小细胞肺癌诊断的灵敏度远高于单项检测。
