Severe lumbar spinal stenosis combined with Guillain-Barré syndrome: A case report

BACKGROUNDGuillain-Barré syndrome (GBS) is a rare disorder that typically presents with ascending weakness, pain, paraesthesias, and numbness, which mimic the findings in lumbar spinal stenosis. Here, we report a case of severe lumbar spinal stenosis combined with GBS.CASE SUMMARYA 70-year-old man with a history of lumbar spinal stenosis presented to our emergency department with severe lower back pain and lower extremity numbness. Magnetic resonance imaging confirmed the diagnosis of severe lumbar spinal stenosis. However, his symptoms did not improve postoperatively and he developed dysphagia and upper extremity numbness. An electromyogram was performed. Based on his symptoms, physical examination, and electromyogram, he was diagnosed with GBS. After 5 d of intravenous immunoglobulin (0.4 g/kg/d for 5 d) therapy, he gained 4/5 of strength in his upper and lower extremities and denied paraesthesias. He had regained 5/5 of strength in his extremities when he was discharged and had no symptoms during follow-up.CONCLUSIONGBS should be considered in the differential diagnosis of spinal disorder, even though magnetic resonance imaging shows severe lumbar spinal stenosis. This case highlights the importance of a careful diagnosis when a patient has a history of a disease and comes to the hospital with the same or similar symptoms.     

新型冠状病毒肺炎中医认识初探

新型冠状病毒肺炎中医属"寒湿疫"范畴,以湿邪为病机核心,以肺为病位中心,以脾胃盛衰为疾病进退的关键。治疗与预防调护方面,急性期,卫气同调,宜宣清和化;恢复期,肺脾同治,宜清补轻宣,注重饮食、情志调摄;谨慎使用抗病毒、抗生素、激素及液体疗法。

萸竹定眩丸治疗痰浊阻络型眩晕的疗效及对外周血FGF-21水平的影响

目的:评价萸竹定眩丸对痰浊阻络型眩晕的治疗效果及对外周血FGF-21水平的影响。方法:120例患者随机分为治疗组和对照组,对照组口服盐酸氟桂利嗪胶囊10mg,每晚1次;治疗组在对照组的基础上给予萸竹定眩丸,每次1丸,每日2次;两组均治疗14天。14天后比较两组患者临床疗效、血脂及外周血中FGF-21水平。结果:治疗组总有效率为93. 3%,对照组总有效率为66. 7%,两组总有效率比较有统计学差异(P 0. 05);治疗后两组FGF-21水平均较治疗前明显降低(P 0. 01,P 0. 05),且治疗组FGF-21水平比对照组降低更明显(P 0. 05);治疗后,两组的TC、TG、LDL-C水平均较治疗前明显下降,HDL-C水平均较治疗前明显升高(P 0. 01),且治疗组的TC水平比对照组下降更显著,HDL-C水平比对照组上升更显著(P 0. 01)。结论:萸竹定眩丸治疗椎-基底动脉供血不足性眩晕(中医辨证属痰浊阻络型眩晕)具有明确疗效;萸竹定眩丸对改善人体的糖脂代谢水平,降低TC,升高HDL-C疗效明确;萸竹定眩丸在临床应用中未发现严重不良反应,临床应用安全可靠。     

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。
