1新辅助放化疗联合全直肠系膜切除术后接受辅助化疗不能改善Ⅱ/Ⅲ期直肠癌患者的无复发生存率显示文摘目的:目前,NCCN指南建议对局部进展期Ⅱ/Ⅲ期直肠癌先行新辅助放化疗(nCRT),然后行全直肠系膜切除术(TME)和辅助化疗。辅助化疗的肿瘤学获益尚未得到进一步证实。本研究的目的是评估nCRT+TME手术后接受辅助化疗的直肠癌患者肿瘤复发和生存情况。方法:本研究是在南加州的14家医院和相关诊所完成的回顾性研究,研究对象为2005年1月1日至2016年12月31日接受手术治疗的862例Ⅱ/Ⅲ期直肠癌患者,无论是否行辅助化疗,纳入研究的患者均接受了新辅助化疗以及全直肠系膜切除术。主要终点是无复发生存率。李来元 VOSS R K LIN J C ROPER M T 2020结直肠肛门外科2020,26,2:5

5脑型和味型代谢性谷氨酸受体的不同功能显示文摘目的 利用脑型及味型mGluR4在体内外的表达 ,检测两种受体结构功能上的差异 ,从而证实它们在信号转导功能上的不同。 方法 将克隆得到的脑型及味型mGluR4分别通过脂质体介导转染CHO细胞。在L MSG和L AP4的作用下 ,检测两种受体的功能。利用WesternBlot及原位杂交技术 ,分别检测它们在体内外的表达。 结果 转染脑型及味型mGluR4的CHO细胞 ,表达两种不同分子量的免疫活性蛋白 ,其中脑型分子量约为 12 0kD而味型约为 6 8kD。在L MSG和L AP4作用下 ,味型mGluR4对刺激物反应的浓度远高于脑型mGluR4。对大鼠脑组织及舌味蕾的原位杂交证明 ,mGluR4在小脑颗粒细胞有很高的表达 ,而在味蕾细胞表达率较低 ,阳性细胞仅占味蕾细胞的 5 %。 结论 味组织中的mGluR4与脑组织中mGluR4在结构和功能上有明显不同。味型mGluR4特异性表达于味蕾细胞 ,在高于脑内的浓度下 ,结合细胞外的谷氨酸 ,通过降低cAMP的浓度引发味觉信号转导。杨慧 徐群渊 Roper S Chandhari N 2002解剖学报2002,33,1:2
