The primary objective of this clinical trial is to assess the clinical efficacy and safety of the Buyuan Zhixiao Formula in treating elderly patients with diabetes and multiple metabolic disorders exhibiting symptoms of renal deficiency and blood stasis. Furthermore, this study aims to intervene in high-risk factors to prevent arteriosclerosis and to investigate the clinical efficacy of the Buyuan Zhixiao Formula in the prevention and treatment of cognitive impairments.
The main questions it aims to answer are:
1. What are the clinical effects of Buyuan Zhixiao Formula, including lowering blood sugar, lowering blood pressure, lowering lipids, and treating obesity? 2. Can Buyuan Zhixiao Formula improve cognitive impairment in diabetes? Researchers compared Buyuan Zhixiao Formula with a placebo (a drug that looks similar but contains only 10% of the active ingredients) to see if the drug Buyuan Zhixiao Formula can treat elderly people with diabetes and multiple metabolic disorders.
Participants will:
1. Take the drug Bu Yuan Zhi XiaoFormula or placebo every day for 6 months；Follow-up for 6 months； 2. Check fasting blood sugar and 2-hour postprandial blood sugar every month; check HbA1c, blood lipids, vascular function, and cognitive impairment serum markers every 3 months; 3. Conduct scores on TCM symptoms, cognitive ability, nutritional status and other scales and adverse events; 4. Urine and serum samples were collected before and after treatment;
1.Age ≥65 years, irrespective of sex;
2.Individuals who meet the Western medical diagnostic criteria for type 2 diabetes mellitus (T2DM) in the elderly, with a hemoglobin A1c level of ≥7.0% in the past three months;
3.Compliance with the diagnostic criteria for abdominal obesity (waist circumference ≥90 cm for males and ≥85 cm for females);
4.Conformity to the diagnostic standards for hypertension (systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg);
1.Exclusion of individuals who, within the past week, have experienced severe infections, acute cardiovascular or cerebrovascular events (such as acute cerebral infarction or myocardial infarction), significant trauma, acute pancreatitis, or other conditions that could precipitate stress-induced hyperglycemia. This also extends to those with concurrent endocrinopathies that may induce insulin resistance, such as Cushing's syndrome, hyperthyroidism, or pituitary growth hormone adenomas, as well as those currently receiving treatment with glucocorticoids or undergoing chemotherapy for malignancies.
2.Exclusion of individuals with a history of neurological disorders or psychiatric conditions that could impair cognitive function, as well as those with a history of medication use for these conditions.
3.Exclusion of individuals with severe complications of diabetes such as diabetic nephropathy in the uremic stage, or those with significant primary diseases of the cardiovascular, cerebrovascular, hepatic, renal, or hematopoietic systems, as well as individuals diagnosed with cancer.
4.Exclusion of individuals with communication barriers that could affect the assessment of cognitive function, including severe impairments in speech, vision, and hearing.
