目的 檢測系統性紅斑狼瘡(SLE)患者血清可溶性黏附分子水平,并分析其與SLE不同中醫辨證分型的相關性及診斷價值。方法 選取SLE患者46例,辨證分型為熱毒熾盛型19例,脾腎陽虛型14例,肝腎陰虛型13例,取晨起空腹靜脈血,采用ELISA法檢測其血清可溶性細胞間黏附分子-1(SICAM-1)及血管內皮細胞黏附分子-1(SVCAM-1)水平變化,并設同期來院體檢正常者40例為對照組,進行對比分析。結果 各證型血清SICAM-1、SVCAM-1水平均顯著高于對照組(P<0.05);熱毒熾盛型血清SICAM-1、SVCAM-1水平顯著高于脾腎陽虛型及肝腎陰虛型(P<0.05);脾腎陽虛型2項指標顯著高于肝腎陰虛型(P<0.05);SLE狼瘡活動積分及ESR以熱毒熾盛型最高,依次為脾腎陽虛型及肝腎陰虛型(P<0.05);熱毒熾盛型及脾腎陽虛型補體C3滴度顯著低于肝腎陰虛型(P<0.05);SICAM-1與SVCAM-1兩種分子間呈正相關性(P<0.01);血清SICAM-1、SVCAM-1水平與狼瘡積分、ERS呈正相關(P<0.01);與補體C3呈負相關(P<0.01)。結論 血清SICAM-1、SVCAM-1水平測定可作為判定SLE活動的重要指標,檢測SLE患者血清可溶性黏附分子水平可作為中醫辨證論治輔助指標。
系統性紅斑狼瘡;辨證分型;可溶性黏附分子
系統性紅斑狼瘡高發于青年女性,是一種自身免疫性結締組織病,可累及機體多臟器,嚴重影響患者生活質量[1-3]。中醫學將其歸屬于“血陰陽毒”“風瘡”“痹證”等范疇,但因臨床及病理表現復雜,中醫對其分型方案尚無統一的辨證方法[4]。從現代醫學的血肌酐、補體、血沉、紅細胞免疫功能、自身抗體、免疫學及細胞因子學等角度對系統性紅斑狼瘡的辨證研究已有報道[5]。本研究通過對系統性紅斑狼瘡不同中醫辨證分型患者血清可溶性黏附分子水平進行檢測,分析其變化及與系統性紅斑狼瘡分型的相關性,結果報道如下。
1.1 一般資料 選取我院2011年1月—2013年1月間收治的系統性紅斑狼瘡患者46例,其中男5例,女41例,年齡21~72歲,平均年齡(28.8±11.2)歲,病程1~30年,平均(7.1±4.6)年。本組患者均符合美國風濕病學會1997年推薦的系統性紅斑狼瘡分類標準;活動積分依據歐洲系統性紅斑狼瘡活動評分標準(1992年)進行判定,其中緩解期13例,活動期33例;經中醫辨證分型為熱毒熾盛型19例,脾腎陽虛型14例,肝腎陰虛型13例,排除其他嚴重繼發性疾病患者。設同期來院體檢正常的女性40例為對照組,年齡20~45歲,平均年齡(29.2±6.7)歲。
1.2 辨證分型標準 依據衛生部頒布的系統性紅斑狼瘡分型診斷標準并由我院中醫科醫師協助進行判定。符合肝腎陰虛型、脾腎陽虛型、熱毒熾盛型3型[6]。
1.3 檢測方法 采各組實驗對象晨起空腹靜脈血3mL,離心機離心,分離血清,-70℃冰箱保存備測;采用酶聯免疫吸附試驗(ELISA)法檢測各組血清可溶性細胞間黏附分子-1(SICAM-1)及血管內皮細胞黏附分子-1(SVCAM-1)水平,檢測儀器采用BENCHMAR BIO-RAD酶標儀,SICAM-1及SVCAM-1試劑盒由北京邦定泰克生物有限公司提供,操作步驟嚴格遵照說明書進行;并采用常規法檢測血沉ESR及補體C3水平變化。
1.4 統計學方法 本研究所得數據采用SPSS 11.0軟件進行分析,采用Spearman相關分析法進行相關性分析,計量資料以均數±標準差(±s)表示,進行t檢驗,P<0.05為有統計學意義。

表2 系統性紅斑狼瘡各證型活動積分、ESP、C3比較
2.3 相關性分析 Spearman相關性分析顯示,系統性紅斑狼瘡患者SICAM-1與SVCAM-1兩種分子間呈正相關性(P<0.01,r=-0.601);血清SICAM-1、SVCAM-1水平與系統性紅斑狼瘡患者狼瘡積分呈正相關(P<0.01,r=0.315,0.413),與ERS呈正相關(r=0.365,P<0.01;r=0.434,P<0.01),與補體C3呈負相關(r=-0.642,P<0.01;r=-0.562,P<0.01)。
系統性紅斑狼瘡是臨床常見的自身免疫性疾病,可累及全身多個系統,發病機制尚未完全明確。目前,中醫學對系統性紅斑狼瘡的診治已取得可喜的成績[7],辨證論治是中醫學制定診治方案的主要依據。但臨床辨證分型多依據患者不適主訴、舌脈、癥狀來進行判定,不夠規范。故本文針對系統性紅斑狼瘡的中醫證型分類及微觀推測指標進行檢測,并進行相關性分析,用客觀臨床指標進行衡量,以期加快對系統性紅斑狼瘡辨證診治的現代化進程。
近年來,系統性紅斑狼瘡發生發展與可溶性黏附分子水平變化的相關性仍是研究的熱點之一[8-11]。可溶性黏附分子屬于免疫球蛋白超家庭,由細胞膜表面的糖蛋白脫落后形成,各種可溶性黏附分子的作用分別代表了炎癥細胞、B細胞與基質間的黏附和內皮細胞的活化[12-14],因此,與系統性紅斑狼瘡發病過程關系密切。熱毒熾盛型、脾腎陽虛型及肝腎陰虛型是系統性紅斑狼瘡臨床常見證型,因此本研究主要對這3種證型進行分析。研究結果顯示,系統性紅斑狼瘡各證型患者血清SICAM-1、SVCAM-1水平均顯著高于對照組(P<0.05);狼瘡活動積分及ESR以熱毒熾盛型系統性紅斑狼瘡患者最高,其次為脾腎陽虛型及肝腎陰虛型,不同分型間狼瘡活動積分比較有統計學意義(P<0.05)。其原因可能與熱毒熾盛型及脾腎陽虛型系統性紅斑狼瘡患者多處于活動期,而肝腎陰虛型患者多處于緩解期有關,提示血清SIVCAM-1,SVCAM-1水平檢測可作為臨床系統性紅斑狼瘡辨證分型的參考。另外,系統性紅斑狼瘡患者SICAM-1與SVCAM-1兩種分子間呈正相關性,提示兩種分子在系統性紅斑狼瘡發生發展中起協同作用;血清SICAM-1、SVCAM-1水平與系統性紅斑狼瘡患者狼瘡積分呈正相關,表明血清SICAM-1、SVCAM-1水平測定可作為判定系統性紅斑狼瘡活動的重要指標。
