摘要
目的 探讨CD68和转化生长因子-β2(transforming growth factor-β2,TGF-β2)在良性前列腺增生(BPH)组织中的表达及临床意义.方法 2016年4—9月应用免疫组化染色检查PV二步法,分别检测90例BPH患者前列腺组织中CD68和TGF-β2的表达情况,并分析CD68和TGF-β2的表达程度与患者临床资料的关系.结果 BPH组织中CD68的阳性表达率为86%(77/90),表达于上皮细胞;TGF-β2阳性表达率为79%(71/90),表达于上皮细胞与间质细胞.根据细胞着色程度将患者分组,随着细胞着色程度的加深,相应患者的前列腺体积更大、IPSS评分更高、最大尿流率更低,组间比较差异均有统计学意义(均P<0.01).结论 CD68和TGF-β2在BPH组织中均阳性表达,且其表达程度与患者的症状、体征成正相关.巨噬细胞介导的炎症免疫反应可能在BPH的发生、发展中起到了重要的作用.
Objective To study the expression and significance of CD68 and TGF-β2 in benign prostatic hyperplasia(BPH).Methods The immunohistochemistry PV two step method was used to detect the expression level of CD68 and TGF-β2 in 90 cases of benign prostatic hyperplasia and combined with clinical data were analyzed.Results Positive rate of CD68 as macrophages marker was 86%(77/90) in the epithelial cells,positive rate of TGF-β2 as transforming growth factor marker was 79%(71/90) in epithelial cells and stromal cells. Immune inlfammation mediated by macrophages,with coloring degree deepening,the degree of immune inlfammation increased,larger prostate volume(P<0.01),IPSS score higher (P<0.01),maximum urinary lfow rate lower(P<0.01),the dffierences between groups were statistically significant.Conclusions This point may indicate immune inlfammation play an important role in the development process of BPH and help to complete the pathogenisis theory.
