Description
技术领域
本发明涉及一种生物化学物质在疾病检测中的新应用。具体而言,本发明涉及人血浆中甘丙肽的检测方法以及甘丙肽在女性抑郁症检测中的应用。
背景技术
抑郁症又称抑郁障碍,是由各种原因引起的以抑郁为主要症状的心境障碍或情感性障碍,涉及遗传、生化、心理和社会环境等多种因素。以持续性心境低落为主要特征,主要表现为情绪低落、精神压抑、易于哭泣,可伴有自卑、自责,患者感到精力疲惫、脑力迟钝、前途暗淡、悲观失望等。抑郁症属于中医情志病范畴,散在于古医籍中郁证、癫狂、脏躁、百合病、惊悸、怔忡、不寐、奔豚气等疾病。随着社会的发展,应激源的增多,抑郁症的发病率呈逐年增长的趋势。研究显示,单相抑郁的终生患病率在10%以上,且女性是男性的2倍左右[Moldin SO,Reich T,Rice JP.Current perspectives on the genetics ofunipolar depression.Behav Genet1991;21(3):211-242]。
抑郁症的发病率、复发率、自杀致残率较高,却面临着检出率低、治疗率低以及治愈率低等特点。世界卫生组织预测,到2020年抑郁症将成为发展中国家仅次于心脏病的第二大疾病,成为最严重的疾病负担[Kessler RC,Berglund P,Demler O.The epidemiology of major depressive disorder:results from the nationalcomorbidity survey replication(NCS-R).JAMA2003,89(2):3095]。
遗传研究认为,抑郁症具有一定的遗传倾向。双生子研究显示,抑郁症的遗传度在40%~50%[Torgersen S.Genetic factors in moderately severe and mildaffective disorders.Arch Gen Psychiatry1986;43(3):222-226]。寄养子研究也提示遗传在抑郁症发病中具有重要作用[Wender PH,Kety SS,Rosenthal D,Schulsinger F,Ortmann J,Lunde I.Psychiatric disorders in the biological andadoptive families of adopted individuals with affective disorders.Arch GenPsychiatry1986;43(10):923-929]。抑郁症先证者一级亲属与普通人群相比,其相对危险度在2~3,复发性抑郁和早发抑郁的相对危险度至少在4~5。但迄今为止,抑郁症的遗传模式还不甚清楚。
源于单胺氧化酶抑制剂[Richelson E.Synaptic effects of antidepressants.JClin Psychopharmacol1996;16(3Suppl2):1S-7S]和三环类抗抑郁药[Tran PV,Bymaster FP,McNamara RK,Potter WZ.Dual monoamine modulation for improvedtreatment of major depressive disorder.J Clin Psychopharmacol2003;23(1):78-86]通过增加突触间隙去甲肾上腺素(去甲肾上腺素)和5羟色胺(五羟色胺)浓度而发挥抗抑郁效应的单胺递质假说是抑郁症病因学的主流假说[Chopra K,Kumar B,Kuhad A.Pathobiological targets of depression.Expert Opin Ther Targets2011;15(4):379-400]。假说认为,抑郁症是中枢去甲肾上腺素和五羟色胺功能不足或缺失所致。大量证据表明:中枢五羟色胺和去甲肾上腺素功能失调与抑郁症发病以及抗抑郁药的作用机理密切相关。但是,递质失调的背后机理不甚明了。
目前,这一假说仍然存在诸多问题。绝大多数抗抑郁药主要针对单胺转运体靶点,增加突触间隙的去甲肾上腺素和五羟色胺水平,发挥抗抑郁作用。但是,抗抑郁药短时间内即可增加突触间隙神经递质,而抗抑郁疗效却要延迟2~4周显示[Davis LL,Wisniewski SR,Howland RH.Does comorbid substance usedisorder impair recovery from major depression with SSRI treatment?An analysis ofthe STAR*D level one treatment outcomes.Drug Alcohol Depend2010;107(2-3):161-170];抗抑郁药的总有效率仅为60%~80%,仍有相当一部分病人缺乏疗效或由于毒副反应放弃治疗[Wong ML,Licinio J.From monoamines togenomic targets:a paradigm shift for drug discovery in depression.Nature ReviewsDrug Discovery2004;3:136-151];以褪黑素为作用靶点的新型抗抑郁药成功研发上市,进一步说明抑郁症病因病理的复杂性,说明目前单胺类假说不能诠释抑郁症的病理机制,促使研究者进一步探讨其具体发病机理。同时,由于抑郁症是一种发作性的疾病,具有一定的自愈倾向。这提示,在机体内部存在某些内源性的保护因素[Zhang JM,Tonelli L,Regenold WT.Effects of neonatal flutamidetreatment on hippocampal neurogenesis and synaptogenesis correlate withdepression-like behaviors in preadolescent male rats.Neuroscience2010;169(1):544-554]。对于这些内源性保护因素的探寻也许会对认识抑郁症发病机理、转归和治疗产生深远影响。
神经调质,尤其是与心境障碍相关的神经肽类,逐渐引起研究者的注意。在脑内,这些神经肽常与经典的神经递质如去甲肾上腺素、五羟色胺、多巴胺等共存。这些调质的一个重要特征就是在应激状态或神经元处于高活性状态下被激活。他们通过多种受体亚型,调节共表达神经元的功能和活性。
甘丙肽在脑内均有较为广泛的分布,参与人体多种高级生理功能的调节,如认知、情感行为、神经损伤等。在中缝背核有95%的五羟色胺能神经元与甘丙肽递质共存,蓝斑80%以上的去甲肾上腺素能神经元与甘丙肽递质共存;无论是蓝斑还是中缝背核所有的甘丙肽能阳性神经元内均有去甲肾上腺素或五羟色胺递质的存在。甘丙肽的受体在蓝斑和中缝背核部位均有表达且有其纤维投射[Kehr J,Yoshitake T,Wang FH.Galanin is a potent in vivo modulator ofmesencephalic serotonergic neurotransmission.Neuropsychopharmacology2002;27(3):341-356]。甘丙肽与中缝背核大部分五羟色胺能神经元和色氨酸羟化酶共表达。因此,甘丙肽系统影响五羟色胺能和去甲肾上腺素能神经元功能。
基于上述研究,本发明主要通过抑郁症患者体内甘丙肽及性激素与抑郁症之间的关联性,探寻神经肽与性激素相关激素间的关系,为女性抑郁症的检测提供新的方法。
发明内容
本发明为检测预防和治疗抑郁症疾病,研究了抑郁症患者血浆中神经肽与抑郁症之间的关联性,研究结果显示,血浆中甘丙肽浓度与女性抑郁症严重程度呈相关性。
本发明根据研究需要设定了样本采集标准,成功采集了700名抑郁症患者的血液样本,对样本进行了性别、年龄、抑郁程度等方面的统计和分层。年龄、发病年龄、体重指数、HAMD、HAMA及其性别差异均无显著性差异。
本发明采用放射免疫的方法测定样本血浆中甘丙肽等神经肽的浓度,统计学研究发现整体样本中甘丙肽浓度与抑郁症严重程度不存在相关性,甘丙肽与HAMD评分之间的相关系数(r)为:0.233(P=0.084),HAMD为汉密尔顿抑郁量表。
性别分层后女性患者血浆甘丙肽浓度与HAMD评分、甘丙肽与睾酮之间存在相关性,相关系数r分别为:0.324(P=0.046),0.421(P=0.014),而男性患者血浆甘丙肽浓度与HAMD评分无显著相关性,r=-0.68(P=0.694)。
本发明通过对抑郁症患者血浆甘丙肽、性激素相关激素与HAMD评分的相关分析首次发现,甘丙肽的血浆浓度与女性抑郁症患者的HAMD评分成正相关,相关系数为0.324(P=0.046)。我们可以通过测定女性抑郁症患者甘丙肽的血浆浓度来推测或判断抑郁症状的严重性,进而为抑郁症的临床评估提供生物学的指标。本发明通过对
本发明还公开了一种检测女性抑郁症的试剂盒,试剂盒中包括甘丙肽抗体,所述甘丙肽抗体可以通过免疫大鼠、小鼠、兔子等哺乳动物,获得甘丙肽多克隆抗体;也可通过经典的杂交瘤技术获得甘丙肽单克隆抗体。
本发明公开了一种检测女性抑郁症的放免试剂盒,包括以下组份:含Galanin抗体的大鼠血清、125I-Galanin(125I标记的的Galanin)、缓冲液、分离剂、正常大鼠血清、Galanin标准品为5、10、20、40、80、160pg/mL;所述缓冲液为200mMpH5.0磷酸盐缓冲液;所述分离剂为兔抗大鼠IgG血清。
本发明还公开了一种检测甘丙肽的方法,包括以下步骤:
1、测定前使样本置于室温或冷水中复融,再3000转/分离心5分钟,取上清液测定。
2、取聚苯乙烯试管编号,T、NSB,S0~S6和待测样品管等。
3、其中编号为NSB管加缓冲液300ul,编号为S0管加缓冲液200μl和含Galanin抗体的大鼠血清100μl;编号为S1~S6管先加100μl缓冲液和100μl含Galanin抗体的大鼠血清,然后分别加入100μl浓度为5、10、20、40、80、160pg/mL的Galanin标准品;样品管加入200ul待测样本上清和100μl含Galanin抗体的大鼠血清;上述各管加样完成后充分混匀,于4℃,放置24小时。
4、上述各管加入100ul125I-Galanin充分混匀,于4℃,放置24小时。
5、上述各管加入100ul正常大鼠血清,充分混匀后,室温静置20分钟。
6、除标记为T的试管,其他各管加入500ul兔抗大鼠IgG血清,混匀,室温放置20分钟,4℃离心3500转/分,25分钟,立即吸取上清液,测定各管沉淀cpm数。
7、实验结果处理如下:
(1)测每份标品管的cpm值并计算出平均数;
(2)按下列式计算各标准管,质控和病人标本的B/130%
B/B0=(B-NSB)/(B0-NSB)×100%
B=为样品管值cpm,B0=标准管B0的cpm值;NSB=非特异性结合管的cpm值;
(3)以各标准管B/130为纵轴,标准物浓度(ng/ml)为横轴在logit-log坐标纸上绘制标准曲线;
(4)在标准曲线上查出质控血清及各标本的甘丙肽浓度。
本发明通过上述方法,检测了376女性的血浆甘丙肽浓度,结果显示当女性抑郁症患者抑郁程度较为严重时,其血浆甘丙肽浓度超过34.54pg/ml;当女性抑郁症患者抑郁程度为中度抑郁时,其血浆甘丙肽浓度为29.73~34.54pg/ml;当女性抑郁症患者抑郁程度为轻度抑郁时,其血浆甘丙肽浓度达为23.55~29.73pg/ml;正常人的血浆甘丙肽浓度小于21.02pg/ml。

2、血浆水平的神经肽浓度及HAMD间的相关分析结果显示,甘丙肽与HAMD评分之间的相关系数(r)为:0.241(P=0.084),(见表3)即甘丙肽与HAMD评分之间不存在相关性。
性别分层后女性患者血浆甘丙肽浓度与HAMD评分、甘丙肽与睾酮之间差异显著,r分别为:0.324(P=0.046),0.421(P=0.014)(见表5),而男性患者血浆甘丙肽浓度与HAMD评分无显著相关性,r=-0.68(P=0.694)(见表4)。

本发明通过对大量的抑郁症患者血浆甘丙肽、性激素相关激素与HAMD评分的相关分析首次发现,甘丙肽的血浆浓度与女性抑郁症患者的HAMD评分成正相关,相关系数为0.324(P=0.046)。这一结果从另一个层面进一步提示甘丙肽功能的性别差异性。
3、不同抑郁程度的女性患者其血浆中甘丙肽的含量
通过对376名女性患者进行17项汉密尔顿抑郁量表(HAMD)打分评定,并检测其血浆中甘丙肽的含量,结果见表6:
表6女性抑郁症患者血浆甘丙肽的浓度
以上实验结果显示当女性抑郁症患者血浆甘丙肽浓度达到至少34.54pg/ml时,其抑郁程度较为严重;当血浆甘丙肽浓度达到在29.73~34.54pg/ml时,其抑郁程度为中度抑郁;当血浆甘丙肽浓度达到在23.55~29.73pg/ml时,其为轻度抑郁;正常人的血浆甘丙肽浓度小于21.02pg/ml。
我们可以通过测定女性抑郁症患者甘丙肽的血浆浓度来推测或判断抑郁症状的严重性,进而为抑郁症的临床评估提供生物学的指标。
