线状银屑病一例

患者男，２５岁。右上肢起皮疹、脱屑，反复发作５年余。５年前右手小指外伤愈后不久，即在原创面起红斑、丘疹、脱屑，并沿小鱼际呈线状向上肢蔓延，微痒，夏重冬轻。近２年来，皮损数目增多，面积增大，向右腋下、右肩胛区扩散，同时右股内侧及右侧阴囊亦出现同样皮疹。...     

新氨基糖苷类抗生素89－07给药方案研究

用小鼠败血症系统感染模型，以感染小鼠肾匀浆活菌计数为标准，以庆大霉素为对照药，探讨日剂量单次与分两次给药两种方案对新氨基糖苷类抗生素８９—０７体内抗留作用的影响。结果表明大肠杆菌９０－０２０、绿脓假单胞菌３—３７４、金葡球菌９０—５０６对抗生素８９—０７和庆大霉素均敏感（ＭＩＣ范围０．０６２５～２ｍｇ／Ｌ）；抗生素８９—０７和庆大霉素日剂量单次给药组（ＯＤ）３株实验菌的肾匀浆活菌计数值由给药前的４．９４±０．０９、４．６０±０．２７、４．８６±０．１０１ｇｃｆｕ／ｍｌ分别降至１．９４±０．１９、１．８４±０．２５、１．８８±０．２５１ｇｃｆｕ／ｍｌ（给药后７～８ｈ）．日剂量分两次给药组（ＢＩＤ）则分别降至２．９５±０．４８、２．８７±０．３７、３．４４±０．２７１ｇｃｆｕ／ｍｌ。ＯＤ组对３株实验菌的最大杀菌作用Ｅｍａｘ分别为３．０２、２．９７和２．８５１ｇｃｆｕ／ｍｌ，ＯＤ给药方案的体内杀菌作用明显优于ＢＩＤ方案。     

运用综合指数对医疗统计指标的评价

<正>医疗统计是医院信息管理的重要组成部分,如何评价医疗质量指标,从总的趋势看已由单项评价过渡到综合评价.只有综合评价才能弥补各种单一方法的不足,才能较客观地反映医院的医疗质量和各科室的实际工作水平.本文试用了综合指数ORAQL的方法,将常规监督性检查统计结果进行综合评价.

胰腺癌黏蛋白4基因修饰的树突状细胞疫苗构建及对胰腺癌细胞的免疫效应

Objective To obtain the dendritic cells ( DC)-based vaccine modified by adenovirus containing MUC4 gene , and evaluate the anti-tumor efficacy of DC vaccine to pancreatic tumor cells. Meth-ods The mRNA sequence of tumor associated antigen, MUC4, was obtained from NCBI, and MUC4 se-quence was acquired through the restriction enzyme sites and over lap PCR, then subcloned into adenovirus plasmid to create recombinant adenovirus ( rAd-MUC4) . The DCs were infected by rAd-MUC4 virus and then stimulated the lymph cells from the same donor to induce MUC4 specific cytotoxicity T lympbocytes ( CTL) . The efficacy of CTL was analyzed by LDH releasing assay. Elispot was used to detect the IFN-γ release. Results The recombinant adenovirus containing MUC4 ( sv12) gene was obtained. The MUC4-induced CTL could specifically kill the Capan-1 pancreatic tumor cells [ ( 13. 7±6.0)% , ( 21.4± 4. 7)% , (36.1±9. 5)% at ratios of 10: ,20: ,40: ] , higher than MCF-7 and Bxpc-3 cells respectively, P < 0. 05. The spots number of CTL induced by rAd-MUC4 was ( 139.1±23.3) , more than GFP and PBS control group,P<0.05. Conclusion The Muc4 gene modified DC vaccine could induce the proliferation of CTL, which provided a significant cytotoxicity to HLA-matched MUC4 positive tumor cell lines in vitro.

早期半卧位预防腹部术后腰肌酸痛的探讨

目的：观察早期半卧位在预防腹部手术后由于被动体位引起的腰肌酸痛的效果。方法：100例患者随机分成2组，实验组患者全身麻醉腹部手术后采用早期半卧位。对照组患者采用去枕平卧位。术后48h内进行观察比较。结果：实验组术后发生腰酸者3例，程度轻，于手术当日发生，次晨消失。对照组术后发生腰酸者13例，程度重，有3例诉腰酸痛难忍。结论：术后早期半卧位能有效预防体位不适而引起的腰肌酸痛。
