人格特征对男性喉鳞状细胞癌患者术后近期心理状况的影响

目的 探讨人格特征对喉鳞状细胞癌（LSCC）患者术后近期心理健康状况的影响。方法 纳入2017年1月—2019年12月在湖北省肿瘤医院行手术治疗的119例男性LSCC患者，术后5~7 d采用SCL-90、SAS、SDS自评量表评估术后心理状态，采用EPQ问卷测评患者的人格特征。多元线性逐步回归方法分析LSCC患者术后近期SAS和SDS评分的影响因素。结果 男性LSCC患者术后SCL-90、SAS、SDS得分显著高于中国常模（P≤0.05），EPQ中精神质（P）量表和神经质（N）量表得分高于中国常模（P<0.01）。男性LSCC患者术后躯体化、强迫、焦虑、抑郁、敌对、恐怖、偏执、精神病性因子得分均显著高于中国常模（P<0.05）。家庭收入、手术方式、术后近期是否行放化疗、P和N人格特征是术后SAS评分的影响因素（均P<0.01）；家庭收入、手术方式、术后近期是否行放化疗和N人格特征是术后SDS评分的影响因素（P<0.01）。结论 LSCC患者术后近期存在抑郁、焦虑等心理障碍；具有P和N人格特征；家庭收入、手术方式、术后近期是否行放化疗以及P和N人格特征是影响术后SAS及SDS评分的独立危险因素。     

RNA sequencing screening of differentially expressed genes after spinal cord injury

In the search for a therapeutic schedule for spinal cord injury, it is necessary to understand key genes and their corresponding regulatory networks involved in the spinal cord injury process. However, ad hoc selection and analysis of one or two genes cannot fully reveal the complex molecular biological mechanisms of spinal cord injury. The emergence of second-generation sequencing technology(RNA sequencing) has provided a better method. In this study, RNA sequencing technology was used to analyze differentially expressed genes at different time points after spinal cord injury in rat models established by contusion of the eighth thoracic segment. The numbers of genes that changed significantly were 944, 1362 and 1421 at 1, 4 and 7 days after spinal cord injury respectively. After gene ontology analysis and temporal expression analysis of the differentially expressed genes, C5ar1, Socs3 and CCL6 genes were then selected and identified by real-time polymerase chain reaction and western blot assay. The mRNA expression trends of C5ar1, Socs3 and CCL6 genes were consistent with the RNA sequencing results. Further verification and analysis of C5ar1 indicate that the level of protein expression of C5ar1 was consistent with its nucleic acid level after spinal cord injury. C5ar1 was mainly expressed in neurons and astrocytes. Finally, the gene Itgb2,which may be related to C5ar1, was found by Chilibot database and literature search. Immunofluorescence histochemical results showed that the expression of Itgb2 was highly consistent with that of C5ar1. Itgb2 was expressed in astrocytes. RNA sequencing technology can screen differentially expressed genes at different time points after spinal cord injury. Through analysis and verification, genes strongly associated with spinal cord injury can be screened. This can provide experimental data for further determining the molecular mechanism of spinal cord injury, and also provide possible targets for the treatment of spinal cord injury. This study was approved ethically by the Laboratory Animal Ethics Committee of Jiangsu Province, China(approval No. 2018-0306-001) on March 6, 2018.

外周血液中miRNA表达与老年性黄斑变性相关性研究

目的　检测微小核糖核酸（microribonucleicacids，miRNA）在老年性黄斑变性（age-related macular degeneration，AMD）患者中的表达，并探讨miRNA的表达量与AMD病程之间的关系。方法　选取2014年1月至2016年11月于同济大学附属第十人民医院眼科门诊就诊的AMD患者6例为试验组，并选取同期6名正常人为对照组，通过基因芯片技术检测两组血液中miRNA的表达量。扩大样本的病例对照研究中共纳入126例AMD患者和140名正常人，检测其血液样本中miRNA的表达，比较两组人群间miRNA的表达量差异。结果　通过基因芯片技术，在试验组与对照组间共检测出216个miRNA存在表达差异（均为P<0.05），与对照组相比，试验组中111个miRNA表达量上升，105个miRNA表达量下降，差异均有统计学意义（均为P<0.05）。扩大样本的病例对照研究结果表明，在AMD患者中，miR-27a-3p、miR-29b-3p、miR-195-5p的表达量显著上升，同时，湿性AMD患者血液中miR-27a-3p的表达量高于干性AMD患者，差异均有统计学意义（均为P<0.05）。结论　AMD患者外周血中miRNA表达量水平有明显变化，miR-27a-3p、miR-29b-3p、miR-195-5p可能成为AMD血清学诊断和预后的标志物。
