摘要： 摘要：目的　探讨环状RNA小脑变性相关蛋白1反义转录物（CDR1as）与微小RNA-7（miR-7）在癫痫患者血浆中的表达及与脑电图异常的关系。方法　选取2016年12月—2019年12月在新乡医学院第二附属医院门诊及住院的癫痫患者87例为观察组，并根据脑电图结果分为正常组（6例）、轻度异常组（18例）、中度异常组（37例）及重度异常组（26例）；选取同期健康体检者90例为对照组。实时荧光定量PCR（qPCR）法检测血浆CDR1as、miR-7水平，酶联免疫吸附测定（ELISA）法检测血浆白细胞介素（IL）-2、肿瘤坏死因子（TNF）-α和IL-1β水平；Pearson法分析癫痫患者血浆CDR1as、miR-7水平与IL-2、TNF-α和IL-1β水平的相关性。结果　对照组、正常组、轻度异常组、中度异常组、重度异常组血浆CDR1as、IL-2、TNF-α和IL-1β水平总体呈升高变化，miR-7水平总体呈降低变化，差异均有统计学意义（P＜0.05）。癫痫患者血浆CDR1as水平与IL-2、TNF-α和IL-1β水平呈正相关（P＜0.05），miR-7水平与IL-2、TNF-α和IL-1β水平呈负相关（P＜0.05）。结论　CDR1as、miR-7在癫痫患者血浆中分别呈高表达、低表达，与炎症因子水平、脑电图异常程度密切相关，可能通过影响炎症反应引起脑部异常放电。

Abstract: Abstract: Objective　To investigate the expressions of circular RNA cerebellar degeneration-related protein 1 antisense (CDR1as) and microRNA-7 (miR-7) in the plasma of epileptic patients and their relationships with abnormal EEG. Methods　A total of 87 epileptic patients treated and hospitalized in the Second Affiliated Hospital of Xinxiang Medical College from December 2016 to December 2019 were selected as the study objects (observation group). According to the electroencephalograph (EEG) results, patients were divided into normal group (n=6), mild abnormal group (n=18), moderate abnormal group (n=37) and severe abnormal group (n=26). In addition, 90 healthy people in the same period were selected as the control group. The plasma levels of CDR1as and miR-7 were detected by real-time fluorescent quantitative PCR (qPCR). The plasma levels of interleukin 2 (IL-2), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were detected by enzyme-linked immunosorbent assay (ELISA). Pearson's method was used to analyze the correlation between the levels of CDR1as, miR-7 and the levels of IL-2, TNF-α and IL-1β. Results　The levels of CDR1as, IL-2, TNF-α and IL-1β were significantly increased in the normal group, mild abnormal group, moderate abnormal group and severe abnormal group (P＜0.05), while the level of miR-7 was significantly decreased (P＜0.05). There was a positive correlation between the plasma levels of CDR1as and IL-2, TNF - α and IL-1 β in epileptic patients (P < 0.05). There was a negative correlation between the level of miR-7 and IL-2, TNF-α and IL-1β (P＜0.05). Conclusion　The plasma expressions of CDR1as and miR-7 are higher and lower in epileptic patients, respectively, and they are closely related to the levels of inflammatory factors and the abnormal degree of EEG, which may cause abnormal discharge of brain by influencing the  inflammatory response.
