杏丁联合吡拉西坦注射液改善血管性痴呆患者认知功能的效应

背景目前国内外对痴呆症治疗方法和药物较多.杏丁和吡拉西坦(脑复康)是一种循环障碍改善剂和神经细胞保护剂,可减慢脑组织功能减退,对认知功能障碍具有改善作用.目的观察杏丁与吡拉西坦联合应用治疗血管性痴呆对认知功能的改善作用.设计以患者为观察对象的病例对照研究.单位河南大学第一附属医院神经科.对象2000-10/2002-03河南大学第一附属医院神经内科住院血管性痴呆患者91例,随机分为治疗组48例和对照组43例.干预治疗组以杏丁注射液20 mL加吡拉西坦8 g分别加入50 g/L葡萄糖注射液250 mL中静脉滴注,1次/d,14 d为1个疗程;对照组以吡拉西坦8 g加入50 g/L葡萄糖注射液250 mL静脉滴注,1次/d,14 d为1个疗程.两组其他治疗药物无差别.两组于治疗结束后1个月以复查简明智能状态检查量表,长谷川痴呆修改量表评估对认知功能的改善,以神经功能缺损评分分析神经功能症状的改善.主要观察指标①两组患者简明智能状态检查量表,长谷川痴呆修改量表及神经功能缺损评分.②疗效分析.结果91例患者均进入结果分析.两组治疗前简明智能状态检查量表和长谷川痴呆修改量表评分相比差异均无显著性意义,治疗组治疗后简明智能状态检查量表和长谷川痴呆修改量表评分(23.26±5.12)分和(2.78±3.46)分]与对照组(19.14±3.21)分和(15.21±2.29)分]比较,差异有显著性意义(t=4.79,15.44,P＜0.01),治疗组治疗后神经功能缺损积分13.68±7.83与对照组17.33±8.81比较,差异有显著性意义,治疗组总有效率(总显效率+进步)为92%,对照组总有效率为56%,两组相比差异亦有显著性意义(X2=15.48,P＜0.01).结论治疗组治疗后简明智能状态检查量表评分高于对照组,长谷川痴呆修改量表评分低于对照组,说明杏丁联合吡拉西坦治疗血管性痴呆能显著改善其认知功能.

Effect of the xingding allied piracetam injection on improvement of cognitive function in patients with vascular dementia

BACKGROUND: At present, there are many drugs and therapeutic methods for dementia at home and abroad. Both xingding and piracetam are the kind of improver for circulatory obstruction and protector for nerve cells and can slow down the functional decline of brain tissue and provide improvement for cognitive deficit.OBJECTIVE: To observe the improvement of allied application of xingding and piracetam on cognitive function in treatment of vascular dementia.DESIGNS: Case-controlled study based on patients.SETTING: Neurological Department in Affiliated Hospital of Henan University. PARTICIPANTS: Totally 91 cases of vascular dementia hospitalized in Neurological Department of First Affiliated Hospital of Henan University from October 2000 to March 2002, which were randomized into treatment group of 48 cases and the control of 43 cases.INTERVENTIONS: In treatment group, xingding injection of 20 mL and piracetam of 8 g were administrated and 50 g/L glucose injection 250 mL was added respectively for intravenous injection, once daily and 14 days made one session. In the control, piracetam of 8 g was prescribed with 50 g/L glucose injection 250 mL added for intravenous injection, once daily and 14 days made one session. There was no any difference in other medication treatment. One month later after treatment of two groups, he patients were re-examined with mini-mental state examination(MMSE) and Hasegawa dementia scale(HDS) was used to assess the cogitative improvement and neurological defect scale(NDF) was used to analysis the improvement of neurological functional symptoms.MAIN OUTCOME MEASURES: ① Scores of MMSE, HDS and NDF in two groups. ② Analysis on therapeutic effects.RESULTS: Totally 91 cases entered the analysis on the results. There was no significant difference in MMSE and HDS before treatment in two groups. In treatment group, after treatment, MMSE and HDS scores were (23.26±5.12) and(2.78±3.46) respectively, indicating significant difference(t=4.79, 15.44, P＜0.01) compared with the control(19.14 ±3.21)and(15.21±2.29) . NDF score was 13.68±7.83 after treatment and the significant difference was presented compared with the control(17.33 ±8.81) . The total effective rate(total remarkable rate + progression) was 92% in the treatment group and was 56% in the control. By the comparison between two groups, the difference was significant(χ2= 15.48, P＜0.01).CONCLUSION: After treatment, MMSE score in treatment group was higher than that in the control and HDS score was lower than that in the control, explaining that xingding allied piracetam significantly improves cogitative function in the treatment of vascular dementia.
