【摘要】 目的:探討rt-PA靜脈溶栓聯合人尿激肽原酶治療急性缺血性腦卒中的臨床效果及對預后的影響。方法:應用隨機數字表法將2018年8月-2019年6月筆者所在醫院收治的80例急性缺血性腦卒中患者分為觀察組及對照組,發病時間<4.5 h,觀察組40例采用rt-PA靜脈溶栓聯合人尿激肽原酶治療,對照組40例采用rt-PA靜脈溶栓治療。對比兩組治療前后NIHSS評分、治療有效率及并發癥發生率,并通過改良Rankin量表評分對比兩組預后情況。結果:兩組治療后NIHSS評分較治療前明顯下降,且試驗組低于對照組(P<0.05);觀察組治療有效率為75.00%,明顯高于對照組的50.00%(P<0.05);觀察組預后良好率為67.50%,明顯高于對照組的42.50%(P<0.05);兩組并發癥發生率比較,差異無統計學意義(P>0.05)。結論:rt-PA靜脈溶栓聯合人尿激肽原酶治療急性缺血性腦卒中的臨床效果顯著,可明顯改善患者預后,且未增加并發癥發生率。

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通過優先激活與纖維蛋白結合的纖溶酶原而使血栓溶解。既往研究表明,即使rt-PA未能將血栓完全溶解,但仍能達到開通部分微血管的功效,可改善患者的遠期預后[5-7]。人尿激肽原酶是從健康男性尿液中提取的一種腦血管擴張劑,能選擇性地擴張閉塞動脈,從而改善微循環,促進新生血管生成,減少細胞凋亡,防止疾病進展[8-11]。
兩組治療后NIHSS評分均較治療前明顯下降,且觀察組治療后NIHSS評分均低于對照組(P>0.05);觀察組治療有效率為75.00%,明顯高于對照組的50.00%(P<0.05);觀察組預后良好率為67.50%,明顯高于對照組的42.50%(P<0.05)。說明rt-PA靜脈溶栓聯合人尿激肽原酶治療急性缺血性腦卒中的臨床效果理想,能有效改善患者NIHSS評分,預后較好[12]。分析原因可能為人尿激肽原酶通過激活一氧化碳-cGMP和前列環素-cAMP信號傳導通路以進一步擴張血管,改善微循環,促進新生血管形成,達到改善預后的目的,并能促進神經功能恢復[13-14]。
本研究中,觀察組并發癥發生率為47.50%,對照組并發癥發生率為45.00%,差異無統計學意義(P>0.05)。說明采用rt-PA靜脈溶栓聯合人尿激肽原酶治療急性缺血性腦卒中未增加并發癥發生率,安全性較高。
綜上所述,采用rt-PA靜脈溶栓聯合人尿激肽原酶治療急性缺血性腦卒中的臨床效果顯著,可明顯改善患者的臨床預后,且未增加并發癥發生率。
