阿片类药物依赖病人手术的麻醉体会

海洛因成瘾者对阿片类药依赖性很强,手术麻醉有其特殊性。本院自1998年1月-2003年3月曾为19例海洛因成瘾病人进行手术麻醉,现报道如下。 资料与方法 一般资料 19例海洛因成瘾者,男15例,女4例,年龄17-42岁,体重38-72 kg。手术急诊15例、择期4例。病

预防食管静脉曲张破裂再出血的临床研究陈胜坚，房太勇，黄好基，黄超，董学峰肝硬化门脉高压食管静脉曲张破裂出血（ＥＶＢ）的发生率与死亡率都较高。首次止血后出血常可再次发生，第一年再出血率不低于４０％～８０％［１］。因此预防再出血很重要。由于患者机体状况不...     

烫伤大鼠细胞免疫抑制与肠源性内毒素血症的关系

采用大鼠４０％ＴＢＳＡⅢ度烫伤模型，将动物随机分烫伤对照组和选择性消脱污染防治组，探讨烫伤大鼠全身性细胞免疫抑制与肠源性内毒素血症的关系。结果显示，大鼠４０％Ⅲ度烫伤后脾细胞对促有丝分裂原增殖应答反应、诱生白介素－２（ＩＬ－２）活性及Ｔ细胞亚群（Ｔｈ／Ｔｓ）比值明显下降，预防性进行ＳＯＤ动物，内毒素血症发生率显著降低，脾细胞增殖应答反应和ＩＬ－２活性的诱生能力均明显恢复（Ｐ〈０．０５￣０．０１），

抗体工程与病理学

结合抗肝癌基因工程抗体的制备，概述了抗体工程的工作内容及其与病理学的关系，抗体工程的主要目的之一是制备人的或接近人的，而能在病人体内应用的抗体，一方面它可以来源于单克隆抗体的改造，首先克隆出鼠抗体可变区的轻链及重链成为小抗体或重组成单链抗体及人鼠嵌合抗体等基因工程抗体。另一方面，也可以用免疫过的小鼠脾细胞或者人的淋巴细胞建立鼠、人抗体库，然后抗原从抗体库中筛选出鼠或人的各种类型抗体。鉴于抗体对靶细胞一般只起导向作用，要携带效应分子才发挥杀伤肿瘤细胞的作用或其它作用。常用的“弹头”有毒素及细胞因子等。所以必须将这种基因与抗体基因融合在一起才能表达有作用的融合蛋白。抗体工程还包括抗体的增效或抗体的成熟，以及对照人抗体的结构进行置换，使抗体人源化等。

Analysis of differentially expressed genes in fetal skin of scarless and scar-forming periods of gestational rats

Objective: To study the differences of gene expression between earlier gestational skin and later gestational skin of rats with the aids of single primer amplification (SPA) and high-density oligonucleotide DNA array to understand the molecular mechanism of scarless healing. Methods: Total RNAs were isolated from fetal rat skin of the scarless (E15) and scar-forming (E18) periods of gestation (term =21.5 days). The RNAs from earlier gestational skin (EGS) and later gestational skin (LGS) were both reversely transcribed to cDNAs, then labeled with the incorporation of fluorescent dCTP for preparing the hybridization probes by SPA method. The mixed probes were then hybridized to the oligonucleotide DNA arrays which contained 5 705 probes representing 5 705 rat genes. After highly stringent washing, these DNA arrays were scanned for fluorescent signals to display the differentially expressed genes between the 2 groups of skin. Results: Among 5 705 rat genes, there were 53 genes (0.93%) with differentially expressed levels between EGS and LGS groups, 27 genes, including fibroblast growth factor 2 ( FGF2 ) and follistatin were up-regulated (0.47%) and 26 genes were down-regulated (0.46%) in fetal skin during scarless period versus scar-forming period. Higher expressions of FGF2 and follistatin in EGS than those in LGS were also revealed by RT-PCR method. Conclusions: High-density oligonucleotide DNA array provided a powerful tool for investigating differential gene expression in earlier and later gestational fetal skins. This technology validates that the mechanism of fetal scarless healing is very complicate and the change of many gene expressions is associated with fetal scarless healing.
