以人单纯疱疹病毒(HSV)基因组即刻早期mRNA4和5拼接区1034~1050密码子序列为靶位点,人工化学修饰、合成特异性8~14mer反义寡聚硫代磷酸型、甲基磷酸型及未修饰型核苷酸(S-ODN14、M-ODN8、N-ODN8)体外抑制病毒活性。S-ODN145~10μmol/L浓度即可抑制HSV致CPE和PFU,M-ODN840~60μmol/L表现明显抑制效应,ELISA检测S-ODN1410μmol/L接近50%抑制病毒抗原表达。M-ODN8的抑制病毒活性剂量呈现细胞毒性。 相似文献

目的探讨正常血压人群以及高血压人群中不同血压昼夜模式与心率变异性(HRV)的相关性分析。方法共入选2009年1月至2010年8月中山大学附属第一医院门诊及病房患者406例,其中高血压病例286例,根据动态血压监测结果分为杓型组、非杓型组和反杓型组,并设对照组120例。全部病例均在监测动态血压的同时记录动态心电图,并分析心率变异性的时域指标。结果非杓型组和反杓型组的SDNN、SDANN、SDNN index、RMSSD、pNN50和Triangular Index值均比杓型组和对照组降低(P<0.05),其中,反杓型组的上述指标明显降低。结论不同血压昼夜模式的高血压病患者HRV指标有明显差别,血压昼夜模式消失的高血压病患者自主神经功能受损更加严重。 相似文献

慢性盆腔炎是指女性内生殖器官慢性炎症[1],多反复发作,且产生一系列并发症,严重影响患者的身心健康.祖国医学无慢性盆腔炎这一病名,根据本病的临床表现及特点,属"妇人腹痛"、"带下"、"月经不调"、"瘕"、"痛经"及"不孕症"等范畴.自2008年12月-2010年08月,笔者应用自拟清热利湿方药治疗本病患者16例,取得满意效果,现报道如下. 相似文献

BACKGROUND: Alpha-tocopherol ( α-tocopherol) can effectively relieve neuronal damage induced by oxygen-centered free radicals. However, the effective dose remains controversial.
OBJECTIVE: To evaluate the protective effects of low-concentration α-tocopherol on neuronal membranes. DESIGN, TIME AND SETTING: Contrast observation and in vitro study, performed at Laboratory of Neurosurgery, Tianjin Huanhu Hospital between April and September 2006.
MATERIALS: Fetal cortical neurons were derived from two 14-day pregnant SD rats, and α-tocopherol was provided by Sigma, USA. METHODS: The neurons were randomly assigned to six groups: (1) normal: neurons were cultured under normal conditions; (2) oxidative damage: oxidative free radicals was damaged using the Fenton reaction; (3) α-tocopherol: neurons were cultured in different concentrations of -tocopherol 10, 20, 40, and 80 mg/L for 2 hours, respectively.
MAIN OUTCOME MEASURES: Neuronal membrane damage was observed using a confocal laser microscope, and malonaldehyde production was detected using the thiobarbituric acid method. RESULTS: At normal, biological concentrations (10 mg/L), α-tocopherol induced no change in the damaged neurons (P 〉 0.05). However, at a concentration of 80 mg/L, the number of damaged neurons was significantly reduced, compared with the damage group (P 〈 0.05). Malonaldehyde levels following 80 mg/L α-tocopherol treatment were less than the oxygen free radical damage group (P 〈 0.05), but greater than the control group (P 〈 0.01). CONCLUSION: A concentration of 80 mg/L α-tocopherol can effectively protect the neuronal cell membrane from oxidative damage 相似文献

纤维鼻咽喉镜检查麻醉方法的效果观察与护理 总被引:1,自引:0,他引:1
纤维鼻咽喉镜是诊治鼻咽喉部疾病的重要手段,一般用传统的喷雾吸入麻醉法,对麻醉不充分者,可导致检查失败,病人出现不良反应.我科于2003年1~10月采用地卡因和利多卡因超声雾化吸入法麻醉,就3种麻醉方法进行分组观察分析,现报告如下. 相似文献

新的医疗保险制度的实施意味着“以药养医”体制的终结。为适应变化的医疗市场,医院管理必须从“政策依赖型”向“市场导向型”转变,用经济杠杆形成医院管理的硬约束。广东省中医院经过几年的探索和努力,通过这一“转变”,使医院取得了较大的发展。我们体会到:调动人的积极性、主动性和创造性,需要一个支点。这个动力支点,就是绩效激励机制。这一机制强调与工作量消费水平、学术水平挂钩,并向科研、服务、管理倾斜,以实现充分挖掘潜力,全方位调动人的积极性。 相似文献

脑细胞间液甘油浓度变化可反映细胞膜的损伤程度,测定脑细胞间液甘油浓度的正常值,并对其在各种病理条件下的意义进行研究有重要意义。联合与甘油有显著相关性的指标如兴奋性氨基酸及乳酸/丙酮酸,可用于评价亚低温的脑保护作用。 相似文献
