Objective To investigate the clinical significance and diagnostic value of plasma D-dimer measurement in response evaluation of female patients with tumor. Methods 149 female cancer patients were enrolled, in which there were 58 post-operative early staged cases(post-operative group), 91 metastatic cases(metastatic group). D-dimer levels before chemotherapy (D1) and after the last cycle of chemotherapy (D2) were assessed and analyzed to examine whether they are correlated to response of therapy. D-dimer levels were presented as median(25^th percentile,75^th percentile) and compared using Wilcoxon signed-rank test(for paired samples) and Mann-Whitney U test(for independent samples). Spearman rank tests were conducted to show the correlation of two variables. Results In post-operative group,D2 was lower than D1(ΔD=-184.8,P<0.0001),and both of D1 and D2 were positively correlated with age(r²= 0.356,0.389,respectively,P<0.01). In metastatic group, after chemotherapy,33 cases had progressive diseases(PD group), while 58 cases gained response or stable diseases(non-PD group). Baseline D-dimer level of PD group was higher than that of non-PD group(1586 vs 754.2,P<0.01),and after chemotherapy the case was similar(2511 vs 525.8,P<0.01). After chemotherapy, D-dimer level increased in PD group(ΔD=1124,P<0.0001), and decreased in non-PD group(ΔD=-153.3,P=0.0045).We compared the abilities of the ΔD(ΔD=D2-D1), D1and D2 to discriminate between responders and non-responders using receiver operating characteristic curves(ROC). The areas under the curve (AUC) of the ΔD, D1and D2, were 0.8603(95%CI:0.7685-0.9520)、0.6740(95%CI:0.5582-0.7597)、0.8956(95%CI:0.8291-0.9621), respectively. The appropriate cut-off values with biggest Youden index of D-dimer for non-responders were as follows: ΔD＜-145.4 ng/mL,D1>1375ng/mL,D2>1033ng/mL. Conclusion Plasma D-dimer level is strongly associated with tumor burden. D-dimer could be used to predict prognosis and treatment response in female patients with tumor.

目的 采用生物信息学方法预测低氧预处理人胎盘绒毛膜间充质干细胞环状RNAs相对应的miRNA及其靶基因,并分析靶基因所参与的生物学过程和信号通路。方法 用Arraystar公司的商业软件为环状RNAs预测其相对应的miRNAs,分别用targetScan7.1和mirdbV5数据库预测miRNAs的靶基因,并取两个预测结果的合集,应用在线网站http://www.geneontology.org和http://www.genome.ad.jp/kegg对靶基因进行功能富集分析和信号通路富集分析。结果 功能富集分析表明,circRNAs的靶基因主要涉及到细胞发育、细胞分化和细胞发育调控。东京基因和基因组百科全书信号通路富集分析表明肿瘤中转录失控和有丝分裂原激活蛋白激酶(MAPK)信号通路最有意义,而且分析发现MAPK信号通路为核心通路。本研究表明,低氧预处理使得间充质干细胞中部分circRNAs的表达量发生差异性变化。结论 低氧预处理人胎盘绒毛膜间充质干细胞环状RNAs同低氧预处理间充质干细胞的生物学特性变化密切有关,为了解低氧预处理影响间充质干细胞特性发生变化的分子机制提供新思路。

Objective To predict the miRNA and its target genes of circular RNAs in hypoxia- preconditioned human palcenta chorionic mesenchymal stem cells using bioinformatics, and analyze the biological process and signaling pathway. Methods Arraystar's commercial software was used to predict the corresponding miRNAs of circular RNAs. The target genes of miRNAs were predicted by targetScan7.1 and mirdbV5 databases respectively, and an intersection of two prediction results was obtained. The online databases http://www. geneontology.org and http://www.genome.ad.jp/kegg performed functional enrichment analysis and signal pathway enrichment analysis of target genes. Results Functional enrichment analysis indicated that the target genes of circRNAs mainly involved cell development, cell differentiation and cell development regulation. The signal enrichment analysis of the Tokyo Gene and Genome Encyclopedia indicates that transcriptional misregulation in cancer and mitogen-activated protein kinase (MAPK) signaling pathway are most meaningful, and the MAPK signaling pathway is found to be the core pathway. This study showed that hypoxic preconditioning caused significant changes in the expression of mesenchymal stem cell circRNAs. Conclusion The changes of circular RNAs in hypoxia-preconditioned human placental chorionic mesenchymal stem cell is closely related to the biological characteristics of hypoxia-preconditioned mesenchymal stem cells. This study provides a new idea for understanding the molecular mechanism of hypoxic preconditioning affecting the changes of biological characteristics in mesenchymal stem cells.
