消栓肠溶胶囊对缺血性脑卒中恢复期患者神经损伤、脑血流灌注及血清CRP和Hcy水平的影响

目的观察消栓肠溶胶囊对缺血性脑卒中恢复期患者神经损伤、脑血流灌注及血清C反应蛋白(CRP)和同型半胱氨酸酶(Hcy)水平的影响。方法选择武汉市第六医院神经内科2017年1～10月收治的92例缺血性脑卒中恢复期患者为研究对象,按照随机数字表法分为观察组和对照组,对照组46例给予西医常规药物治疗,观察组46例在对照组治疗基础上给予消栓肠溶胶囊治疗。治疗4周后,观察两组脑血流灌注[收缩期峰值流速(PSV)、平均流速(TMV)、阻力指数(RI)]、神经损伤[泛素羧基末端水解酶-1(UCH-L1)、神经元特异性烯醇化酶(NSE)、神经胶质原纤维酸性蛋白(GFAP)、S100B蛋白(S100B)]、血清Hcy和CRP水平的变化情况,并统计两组临床疗效,比较两组治疗期间用药安全性。结果观察组治疗后总有效率显著高于对照组(P <0.05);两组治疗后PSV、TMV水平均明显高于治疗前(均P <0.05),RI均明显低于治疗前(均P <0.05),且观察组上述各脑血流灌注指标改善情况均明显优于对照组(均P <0.05);两组治疗后UCH-L1、NSE、GFAP、S100B水平均明显低于治疗前(均P <0.05),且观察组上述各神经损伤指标水平均明显低于对照组(均P <0.05);两组治疗后血清CRP和Hcy水平均明显低于治疗前(P <0.05),且观察组CRP和HCY水平均明显低于对照组(P <0.05);两组用药治疗期间血常规、尿常规、便常规、肝肾功能、心电图、电解质均未出现明显异常,且无严重不良反应发生。结论消栓肠溶胶囊能够显著提高脑血流灌注,抑制血清Hcy和CRP表达,减轻脑组织炎性损伤,优化神经功能,有助于改善缺血性脑卒中恢复期患者的神经功能缺损程度,促进疾病转归。

Effects of Yinxingdamo Injection Combined with Oxiracetam Capsule on Cognitive Function and Neurological Deficit in Patients with Acute Cerebral Infarction

OBJETTIVE: To observe the effects of Yinxingdamo Injection combined with oxiracetam capsule on cognitive function and neurological deficit in patients with acute cerebral infarction. METHODS: A total of 76 patients with acute cerebral infarction were randomly divided into observation group and control group, with 38 patients in each group. Patients in the control group were treated with conventional western medicine and oxiracetam capsules while patients in the observation group were given Yinxingdamo injection intravenous drip treatment on the basis of the same treatment. After 4 weeks of treatment, the cognitive function of the two groups before and after treatment was observed [Simple Intelligence Scale(MMSE Score), Montreal Cognitive Assessment Scale(MoCA Score)], Neurological Deficit [Chinese Stroke Scale(CSS Score), Daily Life Activity ability(ADL score)], free radical biochemical indicators [malondialdehyde(MDA), oxide dismutase(SOD)] changes, and statistical effects of two groups. RESULTS: After treatment, the total effective rate of the observation group was 92.1%, which was significantly higher than 73.7% of the control group(P < 0.05). The MMSE score and MoCA score of the two groups were significantly increased after treatment(P < 0.05), and the MMSE score and MoCA score inobservation group were significantly increased after treatment than the control group(P < 0.05). The CSS scores of the two groups were significantly decreased after treatment(P < 0.05), and the ADL scores were significantly increased(P < 0.05). The improvement of CSS score and ADL score in the observation group were significantly better than those in the control group(P < 0.05), and serum MDA levels were significantly decreased in both groups after treatment(P < 0.05), and SOD levels were significantly increased(P < 0.05), and the improvement of MDA and SOD levels in the observation group was significantly better than that in the control group group(P < 0.05). CONCLUSION: Yinxingdamo injection combined with oxiracetam capsule can effectively inhibit the oxygen free radical reaction injury in patients with acute cerebral infarction, and significantly improve the symptoms of cognitive dysfunction and neurological deficit in patients. Its curative effect is exact and worthy of clinical application.

奶牛乳房炎致病菌多重Taq-Man荧光PCR检测方法的建立

为同时检测大肠杆菌、无乳链球菌和金黄色葡萄球菌,提高对奶牛乳房炎的诊断率,本试验针对3种病原菌的保守序列设计合成了3套特异性引物,通过优化PCR反应体系和反应条件,建立了多重Taq-Man荧光定量PCR检测方法。结果显示,该检测方法具有高特异性,与肠炎沙门菌、肺炎克雷伯菌及鲍曼不动杆菌等无交叉反应;大肠杆菌、金黄色葡萄球菌和无乳链球菌的最低检测浓度分别为103、102和104拷贝数/μL,敏感度较高。DNA各个拷贝数浓度的变异系数均低于2.02%,表明重复性良好。对24份临床采集奶样的检测结果表明,建立的多重Taq-Man荧光定量PCR检测方法可用于临床大肠杆菌、无乳链球菌和金黄色葡萄球菌感染引起的奶牛乳房炎的检测,具有良好的推广应用价值。
