吉林辽宁两省18年来的目标设置对突发公共卫生事件应急工作落实情况的关联研究

目的本研究立足于项目组前期研究的成果上，积极探索吉林辽宁两省目标设置水平的差异，并进一步探究受目标设置影响下的工作落实结果情况，探讨产生差异的原因。 方法以系统穷尽的方式收集吉林辽宁两省2000至2017年有关目标与工作落实情况的指标，利用Spearman相关和线性回归分析吉林辽宁两省目标设置对于突发应急工作落实情况的影响。 结果吉林辽宁两省突发应急领域的目标设置水平与工作落实情况总体均呈现上升趋势，截至2017年，吉林目标设置水平与工作落实情况分别为46%与60%，辽宁为60%与53.3%，且目标设置水平与工作落实呈正相关。 结论有公众需要为依据且定量可考的目标设置对于工作落实、推进、完善具有积极的正反馈作用，建立科学量化的突发应急目标设置评价体系是适宜可行的。     

外周血miR-150-5p、SOCS1 mRNA对类风湿关节炎“病”“证”诊断意义的初步探讨＊

目的 探讨类风湿关节炎患者外周血miR-150-5p、细胞因子信号抑制因子1（suppressor of cytokine signaling 1，SOCS1）mRNA的表达及对类风湿关节炎（Rheumatoid Arthritis，RA）疾病诊断、中医证型判断的意义。方法 纳入符合诊断标准的RA患者57例及健康对照组19例，根据《22个专业95个病种中医诊疗方案》有关RA的中医证候诊断标准，判断RA的中医证型。qPCR检测RA患者及健康对照组miR-150-5p、SOCS1mRNA的相对表达水平，同时检测血常规、肝功能、肾功能等常规指标。双荧光素酶分析方法判断两者是否存在靶向关系。统计分析miR-150-5p、SOCS1 mRNA对RA疾病的诊断意义及其与中医证型的相关性。结果 RA患者外周血miR-150-5p的相对表达水平下调，低于正常人群（t = -19.019，P < 0.05）；其表达水平随疾病活动度升高，有下降趋势；患者外周血SOCS1 mRNA的相对表达水平上调，低于正常人群（t = 5.333，P < 0.05）；其表达水平随疾病活动度升高，有上升趋势。MiR-150-5p与SOCS1 mRNA有靶向结合关系（P < 0.05）。通过AUC曲线比较，miR-150-5p的相对表达水平区分RA的敏感性及特异性分别为98.1%、92.1%（AUC = 0.972，P < 0.05）；SOCS1 mRNA的相对表达水平无法区分RA（AUC = 0.472，P > 0.05）。RA患者中miR-150-5p的相对表达水平低于3.06，RA患者风湿痹阻证、寒湿痹阻证的相对风险分别为8.33、250.00（P < 0.05）。结论 miR-150-5p、SOCS1 mRNA在RA患者中有差异性表达，且有靶向结合关系。miR-150-5p可能是RA的疾病诊断及中医风湿痹阻证、寒湿痹阻证证型诊断的潜在生物标志物。     

不同区域晶状体上皮细胞基因表达差异分析

【目的】比较不同区域猪晶状体上皮细胞的基因表达在转录组水平上的差异。【方法】解剖显微镜下分离晶状体前囊膜，将附着于其上的上皮细胞分为中央（直径为10．56mm）和周边两部分。分别提取两个样本的总RNAs并经PCR扩增，以Cy3和Cy5分别标记扩增的中央与周边部分的cDNA。与含7548个基因的表达谱芯片杂交，经图像分析，生物信息学处理获得基因表达在转录水平差异的相关信息。【结果】中央与周边区域的猪晶状体上皮细胞在转录组水平共鉴定出952个有效表达的基因点，其中差异表达基因261个．以中央区域为参照，周边上皮细胞mRNA上调137个，下调124个。差异表达基因主要涉及的功能有：细胞周期与凋亡、细胞骨架蛋白及细胞外基质、转录、细胞信号分子等。【结论】中央与周边区域猪晶状体上皮细胞基因表达在转录组水平上差异明显。这类差异呈明显的功能聚类。     

Suppression of rotavirus SA-11 reproduction by protease inhibitors in cell culture

The effect of proteases inhibitors, epsilon-amino-caproic acid and gordox, on reproduction of rotavirus SA-11 in MA-104 cells was studied by enzyme immunoassay. These inhibitors were shown to exert an inhibiting effect on rotavirus reproduction.     

Reduced graft-versus-host disease-inducing capacity of T cells after activation, culturing, and magnetic cell sorting selection in an allogeneic bone marrow transplantation model in rats.

Graft-versus-host disease (GvHD), a major complication of allogeneic bone marrow transplantation, has been ascribed to mature T cells in the graft. Because T cells play an important role in engraftment of the bone marrow and decrease the probability of relapse of leukemia, a treatment strategy was developed to preserve the benefits of T cells in the graft and to control the severe complications of GvHD. This can be accomplished by the genetic modification of donor T cells with a suicide gene that allows their selective in vivo elimination and subsequently the abrogation of GvHD. For clinical benefit the alloreactivity of herpes simplex virus thymidine kinase (HSV-TK) gene-transduced T cells should be retained. Therefore, we investigated the influence of gene transduction and the selection procedure on T cells. We demonstrated that activation and culturing of T cells reduce their capacity to induce lethal GvHD in an allogeneic rat bone marrow transplantation model. Furthermore, positive immunomagnetic selection of gene-transduced T cells resulted in loss of the GvHD-inducing capacity of HSV-TK(+) T cells directly after MACS (magnetic cell sorting) selection; this loss could be recovered by a 1-day expansion of the selected T cells. No effect on alloreactivity was observed to be caused by the gene transduction procedure. Our study resulted in the development of an optimized culture and gene transduction protocol with preservation of T cell alloreactivity. Treatment of transplanted rats with ganciclovir resulted in a rapid reduction in the number of HSV-TK(+) T cells in the peripheral blood and in increased survival of the animals.
