目的探讨肌聚糖蛋白α(α-SG)、肌聚糖蛋白β(β-SG)在良性前列腺增生症(BPH)患者膀胱逼尿肌中的表达。方法选择67例住院手术的BPH患者为研究对象,根据排尿后膀胱残余尿量分为尿潴留组31例(>50ml)和非尿潴留组36例(<50ml),并选择同期住院、无BPH且排尿后膀胱内无残余尿的男性膀胱恶性肿瘤患者28例为对照组;采集患者逼尿肌标本,采用免疫组化、Westernblot法检测α-SG、β-SG表达。结果免疫组化显示α-SG、β-SG免疫阳性产物呈棕黄色颗粒,主要位于细胞质,与膀胱逼尿肌细胞走向一致。与对照组相比,尿潴留组α-SG、β-SG表达水平均明显下降,非尿潴留组均明显增加,差异均有统计学意义(均P<0.05)。结论SG在BPH患者膀胱逼尿肌中存在异常表达,可能与BPH临床进展有关。 |

Abstract: |
Objective To investigate the expression of α-sarcoglycan (α-SG) and 茁-sarcoglycan (茁-SG) in detrusor of bladder in patients with benign prostatic hyperplasia (BPH) Methods Sixty seven patients with BPH were enrolled in the study, including 31 cases with urinary retention (>50ml), and 36 cases without urinary retention (<50ml), and 28 bladder tumor patients without BPH and urinary retention as control group. The expressions of α-SG, 茁-SG in detrusor tissue were detected by immunohistochemical technique and Western blot. Results Immunohistochemistry showed that positive staining of α-SG, β-SG was mainly present in the cytoplasm, and arrayed along bladder detrusor cells. Compared to the control group, the expression of α-SG, β-SG in detrusor in urinary retention group was decreased (P<0.05), while the expression in non-urinary
retention group was increased (P<0.05). Conclusion The abnormal expression of sarcoglycans in the detrusor of bladder is associated with the clinical progress of BPH patients. |
