ABSTRACT

Objective To observe the effect of monosialoteterahexosyl ganglioside (GM1) combined with Shuxuening injection on nerve function in patients with acute cerebral infarction (ACI) and its mechanism.Methods A total of 94 patients with ACI admitted to the Department of Neurology in Xiangyang First Peoples' Hospital Affiliated to Hubei Medical College from January 2013 to June 2016 were enrolled,and they were divided into two groups by random number table,each group 47 cases.The patients in two groups were all given conventional western medicine treatment;The patients in one group (single group) were treated by intravenous (Ⅳ) drip of GM1,100 mg once a day;and the patients in another group (combined group),by above GM1 Ⅳ drip combined with Shuxuening intramuscular injection,once 2 mL,twice a day;the therapeutic course in two groups was 14 days.Before and after treatment,the changes of China stroke clinical neurological impairment score (CSS score),glasgow coma score (GCS),nerve factor,oxidative stress index and hemodynamics index of two groups were observed.Results Compared with those before treatment,after treatment the CSS score,the levels of neuron specific enolase (NSE),and malondialdehyde (MDA) were significantly lower,while the GCS score,the levels of nerve growth factor (NGF),neurotrophic factor (NTF),maximum blood flow velocity (Vmax),minimum blood flow velocity (Vmin),mean blood flow velocity (Vmean),mean blood flow quantity (Qmean),glutathione peroxidase (GSH-Px),catalase (CAT) and superoxide dismutase (SOD) were all significantly higher in the combined group (all P ＜ 0.05).After treatment,the CSS score,levels of NSE and MDA in the combined group were significantly lower than those of the single group [CSS:11.20 ± 1.78 vs.16.24 ± 1.95,NSE (μg/L):13.17± 1.00 vs.17.68 ± 1.84,MDA (μmol/L):4.14±0.49 vs.5.61 ±0.50,all P ＜ 0.05],GCS score,NGF,NTF,GSH-Px,CAT,SOD,Vmax,Vmin,Vmean and Qmean of the combined group were all significantly higher than those of the single group [GCS:13.68± 1.85 vs.12.01±1.76,NGF (ng/L):88.10±8.83 vs.68.13±7.16,NTF (pg/L):5.13±0.38 vs.3.71±0.30,GSH-Px (U/L):128.13±8.07 vs.103.90±6.58,CAT (U/L):25.74±2.15 vs.19.43± 1.84,SOD (μU/L):94.36±8.00 vs.77.29±7.34,Vmax (cm/min):48.23±3.36 vs.43.17±2.88,Vmin (cm/'min):8.11±0.76 vs.6.85 ± 0.64,Vmean (cm/min):18.69 ± 1.37 vs.15.60 ± 1.24,Qmean (mL/min):9.10 ± 0.74 vs.7.79 ± 0.66,all P ＜ 0.05].Conclusions GM1 combined with Shuxuening injection can improve nerve function in patients with ACI by improving brain blood flow,secreting neurotrophic related factors and inhibiting oxidative stress reaction,thus it has important clinical significance for repairing the damaged nerve function.
