溃疡性结肠炎中医辨证分型与黏附分子关系的研究

【摘要】 目的 研究溃疡性结肠炎(UC)患者部分黏附分子表达和中医辨证分型的关系。方法 将溃疡性结肠炎患者(UC组)35例辨证分为大肠湿热证(16例)、肝郁脾虚证(8例)、脾肾阳虚证(6例)、血瘀肠络证(5例),用流式细胞术测定各个证型患者外周血中吞噬细胞膜糖蛋白CD44、可溶性黏附分子P—选择素(CD62P)及可溶性细胞间黏附分子—1 CD54的表达情况,并与正常对照组进行比较。结果 大肠湿热证及血瘀肠络证的CD44、CD62P、CD54表达最高,肝郁脾虚证、脾肾阳虚证次之, 与正常对照组比较差异均有统计学意义(P0.01),大肠湿热证及血瘀肠络证间比较差异无统计学意义(P0.05),与其他2个证型比较差异均有统计学意义(P0.01)。肝郁脾虚证及脾肾阳虚证间比较差异无统计学意义(P0.05)。结论 CD44、CD62P、CD54表达与中医辨证分型有关,测定外周血中CD44、CD62P、CD54表达情况可以协助中医辨证分型,确定治疗方案。

Methods 35 patients with UC were divided into 5 groups according to TCM differentiation of syndromes including Dachangshire syndrome group(16 cases), Ganyupixu syndrome group (8 cases), Pishenyangxu syndrome group (6 cases), Xueyuchangluo syndrome group (5 cases). The expression of CD44, CD62P,CD54 in patients’ peripheral blood in different syndromes were detected and compared. Results The expressions of CD44,CD62P,CD54 were highest in Dachangshire syndrome group and Xueyuchangluo syndrome group, next Ganyupixu syndrome group and Pishenyangxu syndrome group, there were significant differences between the 4 groups and normal control group(P0.01),however, there was no significant difference between Dachangshire syndrome group and Xueyuchangluo syndrome group(P0.05),there were significant differences between Dachangshire syndrome group as well as Xueyuchangluo syndrome group and Ganyupixu syndrome group and Pishenyangxu syndrome group(P0.01).But there was no significant difference between Ganyupixu syndrome group and Pishenyangxu syndrome group(P0.05). Conclusion The expression of CD44,CD62P, CD54 is closely related to TCM typing according to differentiation of syndromes, and the detection of expression of CD44,CD62P,CD54 in patients’ peripheral blood is helpful to the TCM typing according to differentiation of syndromes and to selection of treatment plan.   【Key words】 Colitis; Ulcerative; TCM typing according to di fferentiation of syndromes。

溃疡性结肠炎(ulcerative colitis, UC)的病因和发病机制至今仍未清楚。目前多认为与免疫反应异常有关。各种生化介质,包括细胞因子、生长因子、黏附分子—1及一氧化氮(NO)等在介导这一异常的免疫反应中起着重要作用。其中,黏附分子的作用不容忽视。2004—01—2007—02,我们观察了外周血中吞噬细胞膜糖蛋白CD44、可溶性黏附分子P—选择素(CD62P)及可溶性细胞间黏附分子—1 CD54与溃疡性结肠炎中医辨证分型的关系,现报告如下。    1 资料与方法。

1.1 一般资料 观察组35例均为本院消化科门诊(18例)及住院(17例)患者。均符合2000年成都会议制定的UC诊断标准[1];男21例,女14例;年龄23~56岁,平均32.4岁;病程2个月~9年,平均4.5年;根据中医辨证分型标准[2]分为大肠湿热证(16例)、肝郁脾虚证(8例)、脾肾阳虚证(6例)、血瘀肠络证(5例)。正常对照组30例来自同期门诊体检人群。男20例,女10例;年龄22~65岁,平均34.1岁;均无UC、心脑血管疾病、糖尿病病史,无吸烟及服用抗血小板药物史。观察组和对照组的年龄、性别差异均无统计学意义(P>0.05),具有可比性。

1.2 观察方法 用流式细胞术测定各组外周血液中CD44、CD54及CD62P表达情况,所用异硫氰酸荧光素(FITC)标记的单克隆抗体、鼠抗人CD44抗体、鼠抗人CD54抗体、鼠抗人CD62P抗体及同种荧光素标记的阴性对照羊抗鼠IgG抗体,均为法国Immunotech公司产品,FACScan流式细胞仪为美国BD公司产品。

1.3 统计学方法 运用SPSS统计软件处理,计量资料用均数±标准差(x±s)表示,组间比较采用t检验。

2 结果   各组CD44、CD62P、CD54表达情况 见表1。

表1 各组CD44、CD62P、CD54表达情况(略)。

由表1可见,观察组大肠湿热证、血瘀肠络证CD44、CD62P、CD54表达最高,肝郁脾虚证、脾肾阳虚证次之。4个证型与正常对照组比较差异均有统计学意义(P0.01)。大肠湿热证与血瘀肠络证、肝郁脾虚证与脾肾阳虚证比较差异无统计学意义(P0.05),大肠湿热证与肝郁脾虚组证、脾肾阳虚证血瘀肠络证与肝郁脾虚证、脾肾阳虚证比较差异均有统计学意义(P0.01)。
