【摘要】 目的:探討rt-PA静脉溶栓联合人尿激肽原酶治疗急性缺血性脑卒中的临床效果及对预后的影响。方法:应用随机数字表法将2018年8月-2019年6月笔者所在医院收治的80例急性缺血性脑卒中患者分为观察组及对照组,发病时间<4.5 h,观察组40例采用rt-PA静脉溶栓联合人尿激肽原酶治疗,对照组40例采用rt-PA静脉溶栓治疗。对比两组治疗前后NIHSS评分、治疗有效率及并发症发生率,并通过改良Rankin量表评分对比两组预后情况。结果:两组治疗后NIHSS评分较治疗前明显下降,且试验组低于对照组(P<0.05);观察组治疗有效率为75.00%,明显高于对照组的50.00%(P<0.05);观察组预后良好率为67.50%,明显高于对照组的42.50%(P<0.05);两组并发症发生率比较,差异无统计学意义(P>0.05)。结论:rt-PA静脉溶栓联合人尿激肽原酶治疗急性缺血性脑卒中的临床效果显著,可明显改善患者预后,且未增加并发症发生率。

Effect of rt-PA Intravenous Thrombolysis Combined with Human Urinary Kallidinogenase in the Treatment of Acute Ischemic Stroke and Its Influence on the Prognosis of Patients/ZOU Dongyong, JIANG Bo. //Chinese and Foreign Medical Research, 2020, 18(10): -46

[Abstract] Objective: To explore the clinical effect of rt-PA intravenous thrombolysis combined with Human Urinary Kallidinogenase in the treatment of acute ischemic stroke and its influence on the prognosis of patients. Method: A total of 80 patients with acute ischemic stroke admitted to our hospital from August 2018 to June 2019 were divided into the observation group and the control group according to the random number table method. All patients were within 4.5 hours of onset. And 40 cases in the observation group were treated with rt-PA intravenous thrombolysis combined with Human Urinary Kallidinogenase, and 40 cases in the control group were treated with rt-PA intravenous thrombolysis. The NIHSS scores before and after treatment, effective rate, incidence of complications of the two groups were compared, and the prognosis of the two groups was compared by the score of modified Rankin scale. Result: NIHSS scores in the two groups decreased significantly after treatment compared with those before treatment, and the observation group were lower than those of the control group (P<0.05). The effective rate was 75.00% in the observation group, which was significantly higher than 50.00% of the control group (P<0.05). The rate of favorable prognosis of the observation group was 67.50%, which was significantly higher than 42.50% of the control group (P<0.05). The incidence of complications was compared between the two groups, and the difference was not statistically significant (P>0.05). Conclusion: rt-PA intravenous thrombolysis combined with Human Urinary Kallidinogenase has a significant clinical effect in the treatment of acute ischemic stroke, and can significantly improve the prognosis of patients, and does not increase the incidence of complications.

rt-PA通过优先激活与纤维蛋白结合的纤溶酶原而使血栓溶解。既往研究表明,即使rt-PA未能将血栓完全溶解,但仍能达到开通部分微血管的功效,可改善患者的远期预后[5-7]。人尿激肽原酶是从健康男性尿液中提取的一种脑血管扩张剂,能选择性地扩张闭塞动脉,从而改善微循环,促进新生血管生成,减少细胞凋亡,防止疾病进展[8-11]。

两组治疗后NIHSS评分均较治疗前明显下降,且观察组治疗后NIHSS评分均低于对照组(P>0.05);观察组治疗有效率为75.00%,明显高于对照组的50.00%(P<0.05);观察组预后良好率为67.50%,明显高于对照组的42.50%(P<0.05)。说明rt-PA静脉溶栓联合人尿激肽原酶治疗急性缺血性脑卒中的临床效果理想,能有效改善患者NIHSS评分,预后较好[12]。分析原因可能为人尿激肽原酶通过激活一氧化碳-cGMP和前列环素-cAMP信号传导通路以进一步扩张血管,改善微循环,促进新生血管形成,达到改善预后的目的,并能促进神经功能恢复[13-14]。

本研究中,观察组并发症发生率为47.50%,对照组并发症发生率为45.00%,差异无统计学意义(P>0.05)。说明采用rt-PA静脉溶栓联合人尿激肽原酶治疗急性缺血性脑卒中未增加并发症发生率,安全性较高。

综上所述,采用rt-PA静脉溶栓联合人尿激肽原酶治疗急性缺血性脑卒中的临床效果显著,可明显改善患者的临床预后,且未增加并发症发生率。
