萆苓止带片对盆腔炎性疾病后遗症大鼠血清MCP-1、ICAM-1及TNF-α表达的影响

【目的】观察萆苓止带片对盆腔炎性疾病后遗症(SPID)大鼠血清单核细胞趋化蛋白-1(MCP-1)、细胞间黏附分子-1(ICAM-1)、肿瘤坏死因子-α(TNF-α)水平以及血液流变学的影响。【方法】将100只SPF级Wistar大鼠随机分为正常对照组、假手术组、模型组、萆苓止带片组(剂量为0.54 g·kg~(-1)·d~(-1))及妇科白带片组(剂量为0.225 g·kg~(-1)·d~(-1)),每组20只。其中模型组、萆苓止带片组及妇科白带片组大鼠均采用机械刺激加混合细菌法复制SPID大鼠模型。造模2周后灌胃给药21 d,检测各组大鼠子宫肿胀度,血清MCP-1、ICAM-1、TNF-α水平以及血液流变学指标。【结果】与模型组比较,萆苓止带片组及妇科白带片组SPID大鼠子宫肿胀率均有显著降低,其中萆苓止带片组子宫肿胀抑制率高于妇科白带片组(P0.01)。萆苓止带片组及妇科白带片组大鼠血清MCP-1、ICAM-1、TNF-α水平较模型组均显著降低,其中萆苓止带片组降低程度优于妇科白带片组,差异均有统计学意义(P0.05或P0.01)。萆苓止带片组大鼠血液流变学各指标较模型组均显著改善(P0.01),且改善程度优于妇科白带片组(P0.05或P0.01)。【结论】萆苓止带片SPID模型大鼠的治疗效果,与其能抑制大鼠子宫肿胀,降低血清MCP-1、ICAM-1、TNF-α水平,改善血液流变学指标有关。

Effect of Biling Zhidai Tablets on Serum Levels of Monocyte Chemotactic Protein-1, Intercellular Adhesion Molecule-1 and Tumor Necrosis Factor-alpha in Rats with Sequela of Pelvic Inflammatory Diseases

Objective To investigate the effect of Biling Zhidai Tablets(BZT) on monocyte chemotactic protein-1 (MCP-1), intercellular adhesion molecule-1 (ICAM-1)and tumor necrosis factor-alpha(TNF-α)levels as well as hemorheology of rats with sequela of pelvic inflammatory diseases(SPID). Methods One hundred Wistar rats were randomly divided into normal control group , sham-operation group , model group , BZT group(0.54 g·kg-1·d-1)and Fuke Baidai Tablets group(0.225 g·kg-1·d-1), 20 rats in each group . The rats of the model group, BZT group and Fuke Baidai Tablets group were given mechanical damage plus injection of mixed bacteria to induce SPID. After modeling for 2 weeks, the latter three groups were given intragastric administration of the medicine for 21 days. The uterine swelling rate, the serum levels of MCP-1, ICAM-1, TNF-α as well as hemorheological indexes of rats in various groups were detected. Results The uterine swelling rate in BZT group and Fuke Baidai Tablets group was significantly decreased as compared with that of the model group, and the uterine swelling inhibition rate of BZT group was higher than that of Fuke Baidai Tablets group (P<0.01). The levels of MCP-1, ICAM-1 and TNF-α of BZT group and Fuke Baidai Tablets group were significantly decreased as compared with those of the model group, and the effect of BZT group was better than t hat of Fuke Baidai Tablets group, the differences being statistically significant(P<0.05or P<0.01). The indexes of hemorheology in BZT group were significant improved as compared with Fuke Baidai Tablets group, and the improvement in BZT group was superior to that in Fuke Baidai Tablets group (P<0.05 or P<0.01). Conclusion B ZT e xert certain therapeutic effect on treating SPID rats, and the mechanism is related with the relief of swelling of uterus, decrease of serum MCP-1, ICAM-1 and TNF-αlevels and improvement of the indexes of hemorheology.
