Background Detrimental effects of ventricular desynchronization due to long term right ventricular pacing (VP) were well acknowledged.Little study was focused on the unfavorable aspects of increased right atrial pacing (AP).The purpose of this randomized, self-controlled, cross-over study was to test the hypothesis that percentage of AP (％AP) is positively correlated with percentage of VP (％VP) in patients with sick sinus syndrome and intact atria-ventrieular (AV)conduction.

目的 CD8+细胞毒性T细胞(Tc细胞)在机体细胞内免疫及肿瘤免疫中起重要作用.Tc17细胞在宫颈癌患者中的分布情况及其在抗肿瘤免疫中的作用尚未见报道.我们检测了宫颈癌患者外周血及宫颈组织中的Tc17细胞的分布情况,及其与Th17细胞、Treg细胞的关系;同时分析Tc17细胞与临床病理指标的关系,以探讨Tc17细胞在宫颈癌发生发展中的作用,为明确宫颈癌发生的免疫学机制及开展新的治疗靶点奠定基础.
Aim The aim of this study is to investigate the impact of preoperative platelet counts, parameters (MPV,PDW, PCT and P-LCR) and aggregation rates (MAR) on prognosis in patients with epithelial ovarian
目的 探讨DNA损伤修复基因单核苷酸多态性与宫颈癌化疗药物抵抗的关系.方法 本研究纳入了2008-2009年间在复旦大学附属肿瘤医院行根治性手术的70例宫颈鳞状细胞癌患者,采用体外MTT方法分别检测顺铂、卡铂、奈达铂和奥沙利铂对肿瘤细胞的抑制率,并对8个DNA损伤修复基因(ERCC1,ERCC2,ERCC4,ERCC5,ERCC6,XPC,RAD23B,and RAD52)上的13个多态性位点进行
目的 检测IEX-1,HIF-1 α,NF-κB在宫颈癌组织中的表达及相关性,初步探讨其与宫颈癌发生发展之间的关系.方法 应用免疫组化法检测50例宫颈癌组织,40例宫颈CIN(宫颈上皮内瘤样病变)组织及26例正常宫颈组织中IEX-1,HIF-1α和NF-κB的表达,并分析三者的相关性.结果 IEX-1在宫颈癌组织中的阳性表达率明显低于宫颈CIN和正常宫颈组织,差异具有统计学意义(P＜0.05),H
目的 探讨新疆喀什地区伽师县克孜勒博依乡妇女人群HPV(Human papilloma virus,人乳头瘤病毒)感染及高危型HPV的分布特征,以及HPV感染与当地妇女不同程度宫颈病变的关系,为制定新疆农村妇女宫颈癌防治对策和措施以及HPV疫苗的研究提供科学依据.方法 于201 1年6月15日～7月15日在伽师县克孜勒博依乡选择30～60岁的1300例妇女为主要研究对象.所有研究对象接受问卷调查、
目的 前期工作表明,基于卵巢癌生理病理特征,筛选特定的靶向受体,可以获得更为高效的治疗效果和更低的毒副反应.本文选择集中表达于女性生殖系统的卵泡刺激素(Follicle-stimulating hormone,FSH)受体(FSH receptor,FSHR)作为靶位点,构建主动靶向卵巢癌的基因药物递药系统,旨在改善基因药物用于体内治疗时的缺陷.方法 用免疫化学、Western Blot和实时定量
