Association of the insulin-like growth factor binding protein 3 (IGFBP-3) polymorphism with longevity in Chinese nonagenarians and centenarians

Human lifespan is determined greatly by genetic factors and some investigations have identified putative genes implicated in human longevity. Although some genetic loci have been associated with longevity, most of them are difficult to replicate due to ethnic differences. In this study, we analyzed the association of 18 reported gene single nucleotide polymorphisms (SNPs) with longevity in 1075 samples consisting of 567 nonagenarians/centenarians and 508 younger controls using the GenomeLab SNPstream Genotyping System. Our results confirm the association of the forkhead box O3 (FOXO3) variant (rs13217795) and the ATM serine/threonine kinase (ATM) variant (rs189037) genotypes with longevity (p=0.0075 and p=0.026, using the codominant model and recessive model, respectively). Of note is that we first revealed the association of insulin-like growth factor binding protein 3 (IGFBP-3) gene polymorphism rs11977526 with longevity in Chinese nonagenarians/centenarians (p=0.033 using the dominant model and p=0.035 using the overdominant model). The FOXO3 and IGFBP-3 form important parts of the insulin/insulin-like growth factor-1 signaling pathway (IGF-1) implicated in human longevity, and the ATM gene is involved in sensing DNA damage and reducing oxidative stress, therefore our results highlight the important roles of insulin pathway and oxidative stress in the longevity in the Chinese population.     

针刺联合丁螺环酮、右佐匹克隆治疗广泛性焦虑障碍伴失眠的临床疗效观察

目的 探讨针刺疗法联合丁螺环酮、右佐匹克隆治疗广泛性焦虑障碍伴失眠的临床效果.方法 选取我院门诊或住院治疗的63例广泛性焦虑障碍伴失眠患者,按照随机原则分组,对照组(口服丁螺环酮与右佐匹克隆)32例,观察组(对照组药物治疗基础上加针刺治疗)31例,比较两组患者治疗前后汉密尔顿焦虑量表(HAMA)、匹兹堡睡眠质量指数(PSQI)评分情况与治疗有效率.结果 治疗前,观察组与对照组的HAMA、PSQI评分情况比较,差异无统计学意义(P＞0.05),两组治疗4周后,观察组HAMA和PSQI评分与治疗总有效率均显著高于对照组,两组比较差异有统计学意义(P＜0.05).结论 在广泛性焦虑障碍伴失眠患者治疗中加入针刺疗法能够明显改善其焦虑症状,同时改善其睡眠,疗效显著,适合临床推广应用.     

张仲景论治水气病经验浅析及临床体会*

本文从张仲景《伤寒杂病论》论治水气病入手，对其进行归纳、整理和分析，初步探讨其辨证论治水气病规律。张仲景在《内经》“开鬼门，洁净腑”基础上，提出了“诸有水者，腰以下肿，当利小便；腰以上肿，当发汗乃愈”，“有水，可下之”之治疗大法。张仲景论治水气病理、法、方、药千余年来沿用至今，为后世的水肿以阴阳为纲的分类以及从肺、脾、肾论治奠定了基础，同时也为水肿的辨治拓宽了思路。     

不同焦油释放量卷烟全烟气气-液界面暴露致细胞毒性、炎症因子释放和细胞凋亡的研究

目的:探讨两种不同焦油释放量卷烟对人支气管上皮细胞的细胞毒性、炎症因子释放水平和细胞凋亡的影响。方法:选取国际标准化组织(ISO)规定抽吸参数下焦油释放量分别为每支9.4 mg的卷烟样品1和每支14.0 mg的卷烟样品2作为研究对象。实验分为洁净空气对照组和烟气染毒组。利用VITROCELL系统产生的洁净空气或稀释的主流烟气以气-液界面方式暴露染毒Beas-2b细胞,经计算洁净空气对照组剂量为0支卷烟产生的主流烟气,烟气染毒组剂量分别为0.12%支、0.27%支、0.57%支、1%支卷烟产生的主流烟气;利用中性红细胞毒性试验检测细胞存活率;ELISA法检测细胞培养液中的IL-6、IL-8释放水平;Annexin V-FITC/PI流式细胞分析法检测细胞凋亡水平。结果:样品1和样品2产生的主流烟气均可引起Beas-2b细胞存活率降低,炎症因子IL-6、IL-8的释放水平和细胞凋亡率显著增加。在0.12%支的烟气剂量下,样品1与样品2烟气引起的细胞毒性、炎症因子释放水平和细胞凋亡率的差异无统计学意义;在0.57%和1%支的烟气剂量下,样品2的细胞毒性高于样品1。结论:两种不同焦油释放量卷烟样品均可引起细胞毒性、促炎症因子释放和细胞凋亡。在0.57%支~1%支烟气剂量范围内,具有高焦油释放量的卷烟烟气引起的细胞毒性强于低焦油释放量的卷烟烟气。
