    • 摘要: [Abstract]Objective To investigate the changes of T cell immune function in patients with hepatocellu-lar carcinoma(HCC)and its relationship with circulating tumor cells (CTCs), total tumor volume (TTV) and hepatitis B virus (HBV-DNA). Methods Peripheral blood of 45 patients with HCC was collected, and pe-ripheral blood of 45 normal adults was taken as control. CD3+T cells, CD4+T cells and CD4+/CD8+ratio were determined by flow cytometry. CTCs in the blood were detected by CanPatrolTM. The maximum diameter of tu-mor, quantitative hepatitis B virus (HBV-DNA) and other clinical pathological parameters were collected. The HCC patients were divided into high level group and low level group according to the rate of CD4+/CD8+, CTCs, TTV and HBV-DNA level. Results Compared with the healthy control, the percentage of CD3+T cells, CD4+T cells and the rate of CD4+/CD8+in HCC patients were significantly decreased(P0.05). The CD4+/CD8+ratio was positively correlated with TTV (P0.05). Conclusions The immune function of T cells in patients with HCC was disor-dered, and the immune function of T cells was significantly decreased. The immune function of T cell had a close relationship with CTCs and TTV in patients with HCC.%Objective To investigate the changes of T cell immune function in patients with hepatocellu-lar carcinoma(HCC)and its relationship with circulating tumor cells (CTCs), total tumor volume (TTV) and hepatitis B virus (HBV-DNA).

    • 摘要: 目的:了解福建省三明沙县医院健康人群输血传播病毒(TTV)的感染情况方法:准备212名健康人群健康人群者血浆。使用UTR和G1-G5群特异性巢式PCR ,检测血浆中TTV的UTR-DNA 以及5种基因群的DNA。将1-5群部分PCR阳性产物(每1群各两份)进行核酸序列测定,并与15种已定群别的TTV代表株进行同源性比较分析。统计学方法:使用卡方检验(χ2)对检测结果进行分析。结果:(1)使用改良UTR-PCR方法测定,健康人群者TTV感染率为95.3%(212/212),(2)使用群特异性PCR检测TTV,G4群TTV感染率最高,为52.0%(105/212),然后依次为G5:39.1%(79/212),G3:32.7%(66/212),G1:25.7%(52/212),G2:8.4%(17/212)。)。结论:TTV易发生混合群感染,即同一个实验对象可以检测出不同种属于不同群TTV感染。部分阳性产物所测的核酸序列与TTV病毒代表株的核酸序列进行比较分析,认为TTV分群PCR测定是一种可行的TTV感染率检测手段。

    • 摘要: 背景:如何有效治疗新生几呼吸窘迫综合征是各大医院目前研究的重点课题。目的:探讨容量目标通气对新生儿呼吸窘迫综合征动脉血气及安全性的影响。方法:将62例新生儿呼吸窘迫综合征患儿随机分成对照组(n=31)与研究组(n=31),对照组采用同步间歇通气联合辅助模式进行治疗,研究组采用标容量通气+同步间歇通气+压力支持通气模式进行治疗。比较两组动脉血气相关指标、氧疗时间、有创通气时间、住院时间及并发症发生率。结果与结论:研究组有创通气时间、住院时间及低碳酸血症、气漏、呼吸机相关肺炎、脑室周围白质软化发生率低于对照组(P〈0.05),动脉血氧分压,吸入氧体积分数比值、肺泡,动脉血氧分压比值高于对照组(P〈0.05)。表明采用容量目标通气治疗新生儿呼吸窘迫综合征,可显著改善动脉血气水平,缩短有创通气时间及住院时间,降低低碳酸血症及并发症发生率。

    • 摘要: 一、公共卫生安全意义与疫苗研究 Mauro等指出:TTV与其他动物圆环病毒有很多特异的型,尤其是鸡贫血病毒(CAV)。目前尽管只有一个学者报道过在人输血后肝炎(非A—G型)病例中分离出TTV,该病毒也属于动物圆环病毒属,并且在该病例中检测出了PCV抗体。由于该病毒很广泛地存在于猪体内,

    • 摘要: 金刚石线锯是未来切割技术的必然发展趋势。在本文中,通过改造原有的传统砂浆切割机型石井IST500来实现金刚石线锯技术的推广,并且以金刚切专用机PV500作为对比对象。在硅片厚度、TTV方面,指出改造机型石井更有优势;在硅片等级分布方面(完整片数和A率),虽改造机型石井不及金刚切专用面PVS00,但差别不大。从整体上来讲,已成功实现传统砂浆切割机型石井设备的改造。

    • 摘要: 随着现代光电器件工艺的不断改进以及焦平面器件像元数的不断增加,大尺寸晶片越来越受到工艺人员的重视,晶片研磨过程中的表面平整度或总厚度偏差(Total Thickness Variation,TTV)数值有所增加.为了满足工艺人员对大尺寸晶片的要求,降低了研磨工艺中晶片的TTV值.在对不同研磨条件下所得到的晶片的TTV进行研究后,制定了合理的研磨工序.
