Description

血清中EDA-A2作为情绪紊乱类疾病辅助诊断标记物的用途
技术领域
本发明属于生物技术领域,具体涉及一种血清中EDA-A2作为情绪紊乱类疾病辅助诊断标记物的用途,以及制备相应的辅助诊断试剂的应用。
背景技术
抑郁症是一种以持久心境低落、快感消失为主要特征,伴有食欲和睡眠障碍的情感疾病。据统计,抑郁症全球患病率约为4.3%,患病人数超过3亿人,已成为世界范围内的首要致残原因。据世界卫生组织统计,目前抑郁症是造成疾病负担的第四大原因,到2020年抑郁症已成为仅次于心血管疾病的世界第二大造成疾病负担的病因。
目前,关于抑郁症的发病机制学和病理改变说众多,主要有神经发生障碍、单胺类神经递质缺乏、氧化应激障碍以及免疫调节紊乱等,但均未被广泛采纳。此外,现有技术中对于抑郁症的诊断主要依靠症状和问诊以确诊和鉴别诊断,缺乏客观的实验室诊断方法,进而导致抑郁症误诊、漏诊率高,加之传统抗抑郁药物有效率并不理想,较易致使病情迁延。因此,如何准确的进行抑郁症的诊断,对于抑郁症的治疗具有重要的意义。
生物标志物是一种能客观测量并评价正常生物过程、病理过程或对药物干预反应的指示物,筛选抑郁症相关生物标志物将有助于揭示其潜在的病理生理机制,开发出客观的诊断和鉴别方法。因此,筛选抑郁症的病理生理标志物、开发实验室诊断标志物、寻找药物反应标志物的意义重大。研究抑郁症发病机理及可以体现其严重程度的生物标志物,并及时针对病因进行干预与治疗是治疗抑郁症疾病或者情绪紊乱类疾病的关键因素。

具体的,所述情绪紊乱类疾病为血管性痴呆。
现有技术中,所述EDA-A2主要参与毛囊和汗腺的发育,本发明以所述EDA-A2为标志物进行情绪紊乱类疾病的辅助诊断。
本发明还公开了一种基于检测血清中EDA-A2水平进行情绪紊乱类疾病辅助诊断的试剂或产品。
本发明还公开了一种用于辅助诊断情绪紊乱类疾病的试剂盒,包括可检测待测个体血清中EDA-A2水平的试剂。

本发明还公开了一种基于检测血清中EDA-A2水平进行预测和/或判断情绪紊乱类疾病治疗药物效果的试剂或产品。
本发明还公开了一种预测和/或判断情绪紊乱类疾病治疗药物效果的试剂盒,包括可检测待测个体血清中EDA-A2水平的试剂。
本发明以血清中EDA-A2的水平值作为标记物进行情绪紊乱类相关病症的辅助诊断,具有较好的鉴别诊断意义,能够快速进行包括抑郁症等在内的情绪紊乱类疾病的诊断。
本发明进一步以血清中EDA-A2的水平值为标记物,可以实现抗抑郁等情绪紊乱类疾病药物的药效的预测或验证,具有较高的临床意义。
附图说明
为了使本发明的内容更容易被清楚的理解,下面根据本发明的具体实施例并结合附图,对本发明作进一步详细的说明,其中,
图1为实施例1中在执行任务前、后外周静脉血的荧光强度结果;
图2为实施例2中不同地区实验人员血清中EDA-A2的水平测试结果;
图3为实施例3中不同症状实验人员血清中EDA-A2的水平测试结果。
具体实施方式
实施例1蛋白芯片筛选
针对执行某长期任务中面对较大精神心里压力的青年男性,分别于执行任务前、后取外周静脉血,其中,执行任务前样品8例,任务后样品12例。利用的是Raybiotech公司AAH-BLG-1芯片,从507个因子中筛选目标蛋白,读出结果为荧光强度,实验结果见附图1。
经过标准化后,数值越高表明蛋白浓度越高,结果发现,血清中EDA-A2水平下降(p=0.015536),拟把EDA-A2作为焦虑抑郁指征的辅助诊断检测指标,并结合临床症状进行疾病的诊断。
实施例2焦虑抑郁患者临床验证与辅助鉴别诊断
收集2019年6月到2019年8月期间,在解放军总医院第一医学中心就诊的抑郁焦虑症候群患者,共计24例,对照来源于同时期解放军总医院第一医学中心体检但各项指标均正常的健康志愿者,共收集20例。
另外收集2020年10月23日四川省成都市第四人民医院住院的抑郁焦虑症候群患者19例,精神分裂症患者20例,阿尔茨海默病患者13例,血管性痴呆患者6例。分别获取所有对象的肘正中静脉血5ml,室温静置30min,1000×g离心15min,分装冻存于-70℃冰箱。
由于缺乏敏感的ELISA试剂盒,本实施例验证利用的是定制型Raybiotech公司AAH-BLG-1芯片,专门分析各实验人员血清中EDA-A2的水平,实验结果见附图2。
由附图2结果可见,无论是北京的焦虑抑郁症候群患者,还是四川的患者,均呈现出血清中EDA-A2水平下降,其中,北京患者与健康对照的差异显著(p=0.007927),四川患者与健康对照的差异也显著(p=0.008599),而北京患者与四川患者之间无统计学差异(p=0.780366)。
实施例3
将上述实施例2中收集的北京患者和四川患者合并成一组,同健康对照相比,根据不同症状患者统计其血清中EDA-A2的水平,实验结果见附图3。
由附图3结果可见,焦虑抑郁症候群患者血清中EDA-A2水平显著下降(p=0.000915);精神分裂症患者血清EDA-A2水平与健康对照相比也显著下降(p=0.006739),且同焦虑抑郁症候群患者无显著差异(p=0.909253);阿尔茨海默病和血管性痴呆患者血清EDA-A2水平接近(p=0.821091),因为两组患者人数均较少,将两组合并为痴呆组,痴呆患者与健康对照无统计学差异(p=0.914907),且同焦虑抑郁症候群患者差异显著(p=0.003316)。
综上,本发明以血清中EDA-A2水平值为标记物进行情绪紊乱类相关病症的辅助诊断,具有较好的辅助鉴别诊断意义,可用于进行包括抑郁症等在内的情绪紊乱类疾病的诊断。
显然,上述实施例仅仅是为清楚地说明所作的举例,而并非对实施方式的限定。对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
