啤酒多酚物质对啤酒风味稳定性的影响

多酚是啤酒中重要的风味物质，对啤酒质量（非生物稳定性、风味稳定性以及口味）有着重要的影响。作者分析了啤酒中多酚物质的来源以及对啤酒风味稳定性的影响，并利用高效液相色谱测定了啤酒多酚中的单酚物质，研究发现其中的（＋）-儿茶素、（-）-表儿茶素、阿魏酸和槲皮素等单酚具有较高的抗氧化能力。     

鸦胆子素D对HPV16感染细胞株的作用及其可能机制

目的:研究鸦胆子素D对高危型人类乳头瘤病毒(HPV)16感染细胞的增殖抑制作用、促凋亡作用及其可能机制。方法:以人宫颈鳞状上皮永生化细胞株(Ect1/E6E7)作为HPV16型感染的宫颈癌前病变的体外实验模型,用1、5、10、15、30μmol/L的鸦胆子素D分别体外作用于细胞24、48、72 h,用3-(4,5-二甲基噻唑-2)-2,5-二苯基四氮唑溴盐(MTT)法测定细胞增殖活性改变;以1、5、10μmol/L的鸦胆子素D分别体外作用于细胞24、48、72 h后,Cell cycle staining solution检测细胞生长周期变化,Hoechst33258细胞核荧光染色法观察细胞凋亡情况,Annexin V-FITC/PI双染色法检测细胞凋亡率。宫颈癌细胞株Caski含有完整的HPV16型E6、E7基因序列,以此作为阳性对照,通过实时荧光定量PCR技术检测两种细胞内HPV16 E6、E7基因m RNA的表达。结果:鸦胆子素D对Ect1/E6E7细胞具有明显的抑制体外增殖作用,MTT结果显示抑制作用呈时间和浓度依赖性(P<0.05)。经1、5、10μmol/L鸦胆子素D体外作用48 h后,细胞生长周期停滞于G1期。流式细胞仪检测显示,各实验组细胞经鸦胆子素D作用48 h后,细胞凋亡率分别为(6.25±0.76)%、(20.21±1.32)%和(8.61±1.59)%,与对照组比较差异有统计学意义(P<0.05)。Hochest33258细胞核染色法显示细胞出现凋亡形态学改变。Real-time PCR技术检测结果显示Ect1/E6E7中HPV16 E6、E7m RNA表达水平无明显下降,与对照组比较差异无统计学意义(P>0.05)。而Caski中HPV16 E6、E7 m RNA表达水平下降,与对照组比较差异有统计学意义(P<0.05)。结论:鸦胆子素D能有效地抑制Ect1/E6E7细胞增殖,其机制可能是通过抑制HPV16 E6、E7 m RNA表达从而促进细胞凋亡。

人血清激肽释放酶6在上皮性卵巢癌诊断及监测中的意义

Objective The aim of this study was to investigate the clinical value of human serum Kallikrein 6 for the diagnosis and monitor of pithelial ovarian cancer. Methods Serum levels of KLK6 were analyzed with ELISA in 30 cases of epithelial ovarian carcinoma, 20 cases of benign ovarian tumor and 30 cases of healthy women. In the meantime, serum CAi25 was determined with chemiluminescence. Furthermore, serum levels of KLK6 and CA125 were also detected in 12 case of epithelial ovarian carcinoma with the same methods one week and the 3rd month postoperation of follow-up. Results Serum levels of KLK6 in epithelial ovarian carcinoma was higher than that in benign ovarian tumor and healthy women (P < 0.05). KLK6 also showed positive correlation with clinical stage, cytological grade, pelvic lymph node metastasis, recurrent or dead disease (P < 0. 05). On the contrary, KLK6 showed no significant correlation with pathological types (P >0. 05). After surgery of follow-up, KLK6 and CA125 were significantly decreased in 12 case of epithelial ovarian carcinoma (P < 0. 05). Furthermore, the total sensitivity and specificity of KLK6 in the diagnosis of epithelial ovarian carcinoma was 73.3% and 85.0% respectively, followed by the sensitivity to be 50. 0% and 88. 9% for the diagnosis of stage Ⅰ-Ⅱand Ⅲ-Ⅳ disease. Conclusion Our resuits showed KLK6 may be one of the reliable indexes for the diagnosis and monitor of ovarian cancer.     

动脉介入新辅助化疗治疗巨块型宫颈癌60例

[目的]探讨巨块型宫颈癌动脉介入新辅助化疗的疗效及对患者远期生存的影响。[方法]回顾性分析145例巨块型宫颈癌患者，其中新辅助化疗组60例和单纯手术组（对照组）85例。新辅助化疗组给予DDP60．80mg＋EPI50～80mg或DDP80mg＋5-Fu1000mg动脉介入化疗1-2个疗程，化疗后2～3周行根治性子宫切除术＋盆腔淋巴结清扫术，观察化疗后局部肿瘤体积的变化，并比较两组盆腔淋巴结转移、宫颈管浸润、宫旁浸润、阴道切缘肿瘤浸润，术中出血情况，治疗后的近期疗效及远期生存率。[结果]新辅助化疗2周后进行评价，有效率83．3％（50／60），其中完全缓解（CR）12例，部分缓解（PR）38例。宫旁浸润（10．9％，6／55），盆腔淋巴结转移（10．9％，6／55）均低于对照组（27．1％、25．9％）（P值分别为0．032、0．033）。术中出血两组比较差异无显著性（t=0．345，P=0．730）。3年和5年生存率新辅助化疗组为92．35％和72.36％，对照组为78．55％和43．89％，两组差异有统计学意义（P〈0．05）。[结论]巨块型宫颈癌动脉介入新辅助化疗可以缩小局部病灶以利于手术，可以控制淋巴管、血管内转移，提高患者的生存率，但并不增加手术并发症。     

脂肪酸合成酶FAS在卵巢癌中的表达及临床意义

目的 研究脂肪酸合成酶(FAs)在卵巢癌患者中的表达情况及其临床意义.结果 应用免疫组织化学S-P法检测52例卵巢癌、10例交界性卵巢肿瘤、10例良性上皮性卵巢肿瘤中FAS蛋白的表达情况.结果 (1)卵巢癌及交界性卵巢肿瘤中的FAS阳性表达率高于良性上皮性卵巢肿瘤(P<0.01).(2)FAS蛋白表述与组织学类型有关(P<0.01);与病理分级、临床分期无关(P>0.05).(3)FAS蛋白阳性组平均生存时间短于阴性组(22.5月与50.8月),差异有统计学意义(P<0.05).结论 FAS蛋白的过表达可能在卵巢癌的发生、发展中起一定作用,且显著缩短患者术后生存时间,是卵巢上皮性癌患者的不良预后因素.     

肿瘤患者血液和肿瘤组织中穿通支原体的分离与鉴定及其电镜观察

穿通支原体（mycoplasma penetrans，Mpe）是近年来新发现与艾滋病相关的致病性支原体。1986年Tsais和1987年Zhang等报道穿通支原体感染小鼠胚胎细胞C3H6周引起C3H细胞形态学改变，不伴有恶变特征，但至11周即出现恶性改变，18周之后转化不可逆转，并在裸鼠体内形成瘤，提示穿通支原体存在致癌潜能。近年来进一步证实支原体感染与肿瘤发生相关，但报道从肿瘤组织和血液中分离到穿通支原体尚少。为试图从肿瘤患者的血液和肿瘤组织中分离检出穿通支原体，我们随机选取2004年4月至2005年5月在浙江省温州医学院附属第一医院就治的经病理切片确诊的107例肿瘤患者，肿瘤组织和血液进行穿通支原体分离培养、聚合酶链反应（PCR）、序列分析，并取经序列证实穿通支原体检出阳性的血液和肿瘤组织标本在电镜下观察穿通支原体颗粒的存在以及细胞超微结构改变，结果报道如下。
