| 摘要 目的：探究血清肾素-血管紧张素系统（RAS）相关因子[血管紧张素（Ang）Ⅱ、Ang-(1-7)]表达水平与多囊卵巢综合征(PCOS)患者卵巢间质血流的关系。方法：选取2020年7月至2021年10月于我院诊治的PCOS患者88例，按照胰岛素抵抗指数(HOMA-IR)将入选者分为两组，其中HOMA-IR≥2.69者分为胰岛素抵抗组(PCOS-IR组，n=42)，HOMA-IR＜2.69者分为非胰岛素抵抗组(PCOS-NIR组，n=46)。此外，选取同期于我院进行体检的健康女性志愿者90例为对照组。采用酶联免疫吸附法(ELISA)测定血清中的AngⅡ、Ang-(1-7)表达水平，同时采用EPIQ5型彩色多普勒超声仪对所有受试者在采血当天进行卵巢间质血流监测，并计算峰值血流速度（PSV）、搏动指数(PI)和阻力指数(RI)。采用Pearson检验分析PCOS患者AngⅡ、Ang-(1-7)与卵巢间质血流指标的相关性。应用多因素Logistic回归分析PCOS患者卵巢间质血流的影响因素。结果：相较于对照组，PCOS组AngⅡ、Ang-(1-7)、PSV、HOMA-IR水平明显更高，而PI、RI水平则明显更低(P<0.05)；相较于PCOS-NIR组，PCOS-IR组AngⅡ、Ang-(1-7)、PSV、HOMA-IR水平明显更高，而PI、RI水平则明显更低(P<0.05)；Pearson相关分析结果显示，AngⅡ、Ang-(1-7)与PSV、HOMA-IR均呈正相关(P<0.05)，而与PI、RI均呈负相关(P<0.05)；同时AngⅡ、Ang-(1-7)呈正相关(P<0.05)。经多因素Logistic回归分析显示，AngⅡ、Ang-(1-7)、HOMA-IR是PCOS患者卵巢间质血流的相关影响因素(P<0.05)。结论：AngⅡ、Ang-(1-7)在PCOS患者血清中呈高表达，二者之间呈正相关，且在伴有胰岛素抵抗的PCOS患者血清中表达水平进一步升高，两者表达失衡在PCOS患者卵巢间质血流异常增多中起重要作用。 |

| ABSTRACT Objective: To explore the relationship between the serum renin angiotensin system related factors [angiotensin (Ang)Ⅱ, Ang- (1-7)] expression levels and ovarian interstitial blood flow in patients with polycystic ovary syndrome (PCOS). Methods: A total of 88 patients with PCOS who were diagnosed and treated in our hospital from July 2020 to October 2021 were selected, and the candidates were divided into two groups according to the insulin resistance index (HOMA-IR). Those with HOMA-IR ≥ 2.69 were divided into insulin resistance group (PCOS-IR group, n=42), and those with HOMA-IR < 2.69 were divided into non insulin resistance group (PCOS-NIR group, n=46). In addition, 90 healthy female volunteers who underwent physical examination in our hospital were selected as the control group. The serum Ang Ⅱ and Ang-(1-7) expression levels were measured by enzyme-linked immunosorbent assay (ELISA). Meanwhile, the ovarian interstitial blood flow indexes of all subjects were monitored by EPIQ5 color Doppler ultrasound on the day of blood collection, and the peak blood flow velocity (PSV), pulsatility index (PI) and resistance index (RI) were calculated. Pearson test was used to study the correlation between Ang Ⅱ, Ang- (1-7) and ovarian interstitial blood flow in patients with PCOS. Multivariate Logistic regression analysis was used to analyze the influencing factors of ovarian interstitial blood flow in patients with PCOS. Results: Compared with the control group, the levels of Ang Ⅱ, Ang-(1-7), PSV and HOMA-IR in PCOS group were significantly higher, while the levels of PI and RI were significantly lower (P<0.05). Compared with PCOS-NIR group, the levels of Ang Ⅱ, Ang-(1-7), PSV and HOMA-IR in PCOS-IR group were significantly higher, while the levels of PI and RI were significantly lower (P<0.05). Pearson correlation analysis showed that Ang Ⅱ and Ang-(1-7) were positively correlated with PSV and HOMA-IR (P<0.05), but negatively correlated with PI and RI (P<0.05). There was a positive correlation between Ang Ⅱ and Ang-(1-7) (P<0.05). Logistic multifactor regression analysis showed that Ang Ⅱ, Ang-(1-7) and HOMA-IR were related influencing factors of ovarian interstitial blood flow in patients with PCOS (P<0.05). Conclusion: Ang Ⅱ and Ang-(1-7) are highly expressed in the serum of patients with PCOS, and there is a positive correlation between them. The expression levels are further increased in the serum of patients with PCOS with insulin resistance. The imbalance of the two expressions play an important role in the increase of abnormal ovarian interstitial blood flow in patients with PCOS. |
