The invention provides an application of D-serine as a marker in the preparation of diagnostic kit for depression and a diagnostic kit for depression, which relates to the technical field of depression diagnosis. By studying metabolites of abnormal brain lesions in patients with depression, the results show that D-serine is closely related to depression. Therefore, for the first time, D-serine is used as a marker. Objectives are applied in the field related to the preparation of diagnostic kits for depression, which overcomes the impersonality of the indicators currently used in the diagnosis of depression, thus providing a new and more accurate objective diagnostic criterion for the diagnosis of late depression, and further providing a new way of thinking for the diagnosis of depression. The diagnostic kit for depression provided by the invention can quickly and accurately detect the concentration of D serine in the cerebrospinal fluid of the subjects, thereby effectively and accurately determine whether the subjects suffer from depression and the severity of depression.

D-丝氨酸作为标志物在制备抑郁症诊断试剂盒中的应用及抑郁症诊断试剂盒
本专利技术涉及抑郁症诊断
,尤其是涉及一种D-丝氨酸作为标志物在制备抑郁症诊断试剂盒中的应用及抑郁症诊断试剂盒。
技术介绍
人的抑郁情绪属于负性情绪,持续时间过长会形成病理性精神疾病,如抑郁症。抑郁症是一种由多种原因导致的以持续情绪低落为主要症状的精神疾病,其临床表现为多样,往往伴随焦虑、快感缺失和社交障碍等。抑郁症是精神科常见疾病,世界卫生组织预计,到2020年,抑郁症将会成为第二大常见疾病。抑制症发病机制复杂,涉及多系统、多环节的功能失调,可表现为多种生化物质的动态平衡异常。但令人遗憾的是,抑郁症的病因至今尚不完全清楚,并且,目前临床上对抑郁症的诊断多数依赖于各种量表进行的评分法,如比较常用的焦虑自评量表(Self-ratinganxietyscale,SAS)或抑郁自评量表(Self-ratingdepressionscale,SDS)。而不管哪种形式的量表,都属于主观诊断范畴,缺乏客观的依据和标准。目前,尚缺乏与抑郁症诊断相关的生物标志物等客观指标。有鉴于此,特提出本专利技术。专利 ...
