ABSTRACT
Objective: To observe the clinical efficacy of Peiyuan Tongnao capsule combined with "Zhisanzhen" for post-stroke dementia (PSD) and investigate its mechanism.Method: Ninety-eight eligible patients were randomly divided into control group (49 cases) and observation group (49 cases) by random number table.Both groups received donepezil tablet,10 mg/time,qd,and nimodipine tablet,30 mg/time,qd.Patients in control group additionally took "Zhisanzhen" ,qd,5 times/week.Based on the treatment in control group,patients in observation group additionally took Peiyuan Tongnao capsule,3 capsules/time,tid.The treatment course was 12 weeks.Before and at the 4th,8th and 12th week after treatment,mini-mental state examination (MMSE),montreal cognitive assessment (MoCA),activity of daily living scale (ADL),neuropsychiatric inventory (NPI) and symptoms of traditional Chinese medicine (TCM) were evaluated.Before and after treatment,levels of serum hyperhomocysteinemia (Hcy),hepatocyte growth factor (HGF),oxidized low density lipoprotein (Ox-LDL) and acetylcholinesterase (AchE) were detected.Result: The total clinical effective rate was 93.88% in observation group,better than 77.55% in control group (χ2=5.333,PFcontrol=3.947,Fobservation=5.833,PFcontrol=3.876,Fobservation=6.011,Pth and 12th after treatment,scores of MMSE in the observation group were all higher than those in control group (Pth week after treatment,score of MoCA in observation group was higher than that in control group (PPPPPConclusion: Peiyuan Tongnao capsule combined with "Zhisanzhen" can improve cognitive and behavioral abilities,improve clinical efficacy,ameliorate abnormal mental behavior,relieve clinical symptoms,and regulate levels of Hcy,Ox-LDL,AchE and HGF in the treatment of post-stroke dementia.
ABSTRACT
Objective: To discuss the effect of Peiyuan Tongnao capsules on neurological impairment of patients with ischemic stroke at convalescence, and discuss the mechanism of action in microcirculation improvement, anti-inflammation and neuroprotection. Method: One hundred and thirty one patients were randomly divided into control group (66 cases) and observation group (65 cases) by random number table. Patients in control group were given aspirin enteric-coated tablets, 0.1 g/day, simvastatin tablets, 10 mg/days, and treated by percutaneous nerve electrical stimulator for 30 times, 30 min/time, 1 time/day, 5 times/week. In addition of the therapy in control group, patients in observation group were also given Peiyuan Tongnao capsules, 3 grains/time, 3 times/days. A course of treatment was 12 weeks. Before treatment, and at the 4th, 8th and 12th weeks, neurological deficits in the national institutes of health (NIHSS), activity of daily life scale (ADL), berg balance scale (BBA), fugl-meyer scale (FMA) and traditional Chinese medicine (TCM) syndromes were scored. And levels of brain-derived neurotrophic factor (BDNF), neuron-specific enolase (NSE), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), homocysteine (Hcy) and serum cystatin C (Cys-C) and hemorheological indicators whole blood viscosity, high shear rate, low shear rate, reduced viscosity, plasma viscosity, platelet aggregation rate, fibrinogen (FIB) and blood sedimentation rate (ESR)were detected. Result: At the 8th and 12th week after treatment, score of NIHSS in observation group was lower than that in control group (PPPα, Hcy, Cys-C and hemorheological indices were all lower than those in control group (PPConclusion: Peiyuan Tongnao capsules can promote the recovery of neurological impairment at recovery period of ischemic stroke, regulate inflammatory factors, improve blood rheology, protect neural function, and improve the effect of routine western medicine rehabilitation therapy.
