In order to observe clinical therapeutic effect of Shen Ma Yi Zhi Capsule on senile vascular dementia (VD), 68 cases of VD were randomly divided into the treatment group treated with Shen Ma Yi Zhi Capsule and the control group treated with Western medicine Trigogine, and double blind and double simulation methods were adopted for administration of drugs. Results indicated that Shen Ma Yi Zhi Capsule could obviously improve clinical symptoms, increase cumulative score of intelligence rating scale, improve memory and gnosia function, restore nervous function improve daily living capability, indexes of blood rheology and cerebral function. The treatment group in improvement of symptoms was superior to the control group. It is suggested that Shen Ma Yi Zhi Capsule has definite therapeutic effect for senile VD, with no adverse effect.

Objective To explore the relationship among the disease - syndrome - formula of type 2 diabetes.Methods Based on the clinical data of 2501 cases of type 2 diabetes, to study the relationship among the disease - syndrome - formula of type 2 diabetes by making use of association rules.Results Three formulas, Shengmai Yin (Pulse-activating Fluid), Liuwei Dihuang Decoction (Decoction of Six Herbs Including Rehmannia), and Sijunzi Decoction (Decoction of Four Noble Herbs), were selected from 122 ones to analyze the relationship between the formula and symptoms. The occurrence of fatigue with weakness, dry mouth with thirst, frequent urination with increased volume of urine, numbness of limbs, blurred vision, thirst with preference of drinking water, frequent nocturnal urination, and shortness of breath with inactive talking was in high frequency in those patients who were prescribed Shengmai Yin. The occurrence of fatigue with weakness, thirst with preference of drinking water, blurred vision, frequent nocturnal urination, dry mouth with thirst, numbness of limbs, shortness of breath with inactive talking, and soreness and weakness of lumbus and legs was in high frequency in those patients prescribed Liuwei Dihuang Decoction, and there existed a multi-association among these symptoms. The occurrence of fatigue with weakness, soreness and weakness of lumbus and legs, frequent nocturnal urination, shortness of breath with inactive talking, numbness of limbs, insomnia, and blurred vision was in high frequency in those patients who were prescribed Sijunzi Decoction, and there existed a multi-association among these symptoms.Conclusion The association rule can be adopted to analyze the relationship between formula and syndrome, and to explore the multi-association relationship among the symptoms of type 2 diabetes.

Objective To explore characteristics of the elements of syndrome, the disease position and the relationship between chemical indicators and TCM syndromes of type 2 diabetic encephalopathy. Methods 2 501 cases of type 2 diabetes clinical data were collected from Guang'anmen Hospital of China Academy of Chinese Medical Sciences, Beijing University of Chinese Medicine, Dongzhimen Hospital, Dongfang Hospital, etc. in nearly 3 years, among which, 342 cases were type 2 diabetic encephalopathy. The original clinical data were double entried in epidata by two people, establishment forms in excel, factor analysis and Bayesian networks were used as data mining research methods. Results 20 elements which characteristic root more than 1 were derived by factor analysis, 68.4% were covered. Of all 20 elements, five factors belong to Yin, five factors belong to blood stasis; lassitude, shortness of breath, stool frequency were appeared when fasting glucose abnormalities; lassitude, hemiplegia were appeared when 2-hour postprandial blood glucose abnormalities;lassitude, feverish palms and soles, stool frequency, more nocturnal enuresis when glycated hemoglobin abnormalities by Bayesian networks. Conclusion The Elements of the syndrome of type 2 diabetes encephalopathy were deficiency of Yin and blood stasis; and the main positions for diabetic patients were liver, spleen and kidney. Patients with impaired fasting glucose were Qi deficiency; Patients with impaired 2-hour postprandial glucose were Qi deficiency or pathogenic wind attacking collaterals; Patients with abnormal hemoglobin were Qi deficiency and Yin deficiency.

Objective To systematically evaluate the efficacy and safety of oral preparation of ginkgo biloba in treating vascular dementia (VD).Methods A fully literature search was conducted in CNKI,Wanfang,Sinomed,VIP databases,PubMed,Embase,the Cochrane Library and Clinical Trails with the deadline of October,2018 for randomly controlled trials of oral preparation of ginkgo biloba for vascular dementia.After assessing the quality of literatures included,RevMan5.3 software was used to analyze the extracted data.Results A total of 17 studies which including 1 326 patients were involved.The results of meta-analysis showed that:compared with the western medicine group,oral ginkgo biloba preparation combined with western medicine group was much better in the MMSE assessment [MD=2.89,95％ CI (2.06,-3.72),P=0.000 1],there was no significant difference between the western medicine group and the pure oral ginkgo biloba group in the ADL assessment [MD=-3.00,95％ CI (-4.69,-1.30),P=0.000 5] and overall clinical status assessment [RR=1.29,95％ CI (1.20,1.39),P＜0.000 01],the efficacy of the pure oral ginkgo biloba group and western medicine group was similar in the ADL assessment [MD=-0.93,95％ CI (-3.48,1.63),P=0.48].Conclusions Based on the meta-analysis,oral preparation of ginkgo biloba combinedwithwestemmedicinehas certain advantages compared with conventional western medicine treatment alone,but a large number of large-sample and high-quality trials are requiredtofurther prove and review its effect
