Clinical Study of GKT in Diabetes Related Dementia

Recently a new clinical dementia subgroup based on brain imaging, called "diabetes related dementia (DrD)". DrD, unlike Alzheimer's disease and vascular dementia, is considered a "controllable" or "modifiable" form of dementia. However, there is currently a lack of corresponding treatment measures. Ginkgo biloba ketone ester tablets are extracts of Ginkgo biloba leaves. Previous studies have shown that they can increase cerebral blood flow, reduce cerebrovascular resistance, improve cerebral circulation, and are beneficial for the treatment of cognitive impairment. This project intends to explore the role of ginkgo ketoester tablets in diabetes related dementia through a multicenter randomized double-blind controlled clinical study.

This study was divided into two treatment groups: the experimental group and the control group. 196 type 2 diabetes patients with mild cognitive impairmentpatients were randomly selected and assigned to the experimental group of 98 patients and the control group of 98 patients in a 1:1 equal amount. Experimental group: Ginkgo biloba ketone ester tablets combined with conventional hypoglycemic treatment group, the usage is Ginkgo biloba ketone ester tablets (Styron), taken orally, 3 times a day, 0.5g each time, and continuously administered for 6 months. Control group: conventional hypoglycemic treatment group. The Montreal Cognitive Assessment Basic (MoCA-B) was used for the detection of cognitive dysfunction. Neuropsychological testing of cognitive function was conducted using Alzheimer's Disease Assessment Scale - Cognitive Scale (ADAS-cog), Auditory Word Learning Test (AVLT-H);Assessment of Daily Living Ability - Functional Activity Questionnaire (FAQ);Shape Connection Test A and B and Symbolic Digital Form Test (SDMT).Collect patients' blood, and detect C-reactive protein, interleukin-6, oxidative stress, ApoE4 genotype, phosphorylated tau protein, irisin, β- Amyloid protein before and after the experiment.Detect changes in ankle brachial pulse wave conduction velocity (baPWV)/and ankle brachial blood pressure index (ABI) of patients before and after the experiment.

Ginkgo Ketone Ester Tablets (Styron), taken orally, 3 times a day, 0.5g each time, continuously administered for 6 months

Alzheimer's Disease Assessment Scale-Cognitive section (0-70), the higher the score, the more severe the cognitive impairment

Functional Activity Questionnaire (FAQ)S,the higher the score, the more severe the cognitive impairment

Shape Connection Test A and B (STT-A&B)，the higher the score, the more severe the cognitive impairment

Human CRP(C-Reactive Protein) ELISA Kit for detecting C-reactive protein concentration (mg/L )in serum

ankle brachial blood pressure index (ABI) measures ankle blood pressure and upper arm brachial artery blood pressure through ankle brachial index instrument

Inclusion Criteria: Type 2 diabetes with mild cognitive impairment patients aged 65 years or above; Able to cooperate in completing cognitive function testing; Patients who can swallow pills No previous history of acute stroke Exclusion Criteria: Type 1 diabetes; Acute cerebral infarction and myocardial infarction within 3 months; Severe liver and kidney dysfunction; Late stage malignant tumors; Thyroid dysfunction； Brain injury and cerebral hemorrhage within 3 months； Folic acid and/or vitamin B12 deficiency Patients who are currently using thrombin inhibitors, defibrillators (with unclear efficacy in ischemic stroke and increased risk of bleeding), antiplatelet drugs, blood activating and stasis resolving agents, and other ginkgo biloba leaf preparations (as they may affect the evaluation of the therapeutic effect of ginkgo biloba ester tablets in this trial), as well as other trial medications.
