“河车助孕方”对不育症子宫内膜雌激素受体、孕激素受体、增殖细胞核抗原及血管内皮生长因子的影响

目的 :探讨补肾调经中药治疗不育症的机理。方法 :应用免疫组织化学方法 ,观察服用“河车助孕方”前、后增殖晚期子宫内膜雌激素受体 (ER)、孕激素受体 (PR)、增殖细胞核抗原 (PCNA)及血管内皮生长因子 (VEGF )表达的变化 ,并以服药前作为自身对照。结果 :服药前 ER、PR、PCNA、VEGF在子宫内膜腺上皮细胞核的表达分别为 0 .18± 0 .3 9、0 .88± 0 .3 8、1.76± 0 .5 0、0 .15± 0 .2 9;在内膜间质细胞核的表达分别为 0 .71±0 .44、0 .79± 0 .47、1.12± 0 .47、0 .2 6± 0 .3 6;服药后在子宫内膜腺上皮细胞核的上述各项表达分别为 2 .12± 0 .40、2 .3 2± 0 .3 5、3 .15± 0 .49、1.79± 0 .44 ,与服药前比较 ,P均 <0 .0 0 1;在内膜间质细胞核的表达分别为 1.5 3± 0 .41、1.88± 0 .3 8、2 .18± 0 .5 0、2 .0 6±0 .3 9,与服药前比较 ,P均 <0 .0 0 1;服药后子宫内膜腺上皮细胞、间质细胞的 PCNA、VEGF表达亦明显增强。结论 :补肾调经中药“河车助孕方”可增加子宫内膜 ER、PR的合成 ,并使激素依赖性的 PCNA、VEGF表达增强 ,从而促进内膜正常生长、发育 ,有效地改善不育症患者子宫内膜的微环境。

The effect of Chinese herbal medicine“heche assisted pregnancy recipe”on endometrial estrogen and progesterone receptor,proliferating cell nuclear antigen and vascular endothelial growth factor in the patients with infertility

Objectives:To investigate the effect of Chinese herbal medicine"heche assisted preg-nancy recipe (HCAPR)" on estrogen receptor(ER), progesterone receptor (PR), pro-lifierating cell nuclear antigen(PCNA) and vascular endothelial growth factor (VEGF)in endometrium of infertile women.Methods: The S-P immunohistochemical assay was used to observe expression ofER, PR , PCNA and VEGF in late proliferative phase before and after the HCAPR treat-ment.Results: After the treatment, the expression of ER,PR,PCNA and VEGF in nucleiof glandular epithelium and stromal cells was significantly stronger (all P＜0. 001) re-spectively than that before treatment , especially the expression of PCNA and VEGF.Conclusions: These results suggest that traditional Chinese medicine HCAPR oftonifying kidney and regulating menstruation increased the synthesis of ER,PR, PCNAand VEGF, which may promote normal growth and development of the endometrium ,improve the micro-environment of the endometrium, and enhance uterine receptivity.The evidence may provide theoretical basis for therapy infertility with Chinese herbalmedicine.
