[Effect of Naoxintong Capsule on Vascular Remodeling in Type 2 Diabetic Patients with Subclinical Vascular Disease].

Objective To observe the effect of Naoxintong Capsule (NC) on carotid artery vas- cular remodeling (VR) in type 2 diabetes mellitus (T2DM) patients with subclinical vascular disease. Methods A total of 180 T2DM patients with subclinical atherosclerosis (AS) were randomly assigned to the observation group and the control group in the ratio of 1:1 , 90 in each group. All patients took conven- tional hypoglycemic therapy, and the choices of therapeutic drugs and doses were selected according to patients' conditions. Patients in the observation group additionally took NC (3 pills each time, three times per day) , while those in the control group took no interventional drug. The therapeutic course for all was 6 months. The size and nature of bilateral carotid artery plaque were measured before and after treatment using color Doppler ultrasound diagnostic instrument. Bilateral carotid artery intimal-medial thickness (IMT) , plaque area (PA) , total vascular area (TVA) , lumen area (LA) , peak systolic velocity (PSV) , end diastolic velocity (EDV) , vascular resistance index (VRI) , and pulsatility index (PI) were measured. The total plaque score, unstable plaque detection rate, stenosis rate (S) , and refactoring index ( RI) were calculated. Levels of fasting plasma glucose (FPG) , glycated hemoglobin Al c (HbA1 c) , triglyceride (TG) , total cholesterol (TC) , high density lipoprotein cholesterol ( HDL-C) , and low density lipopro- tein cholesterol (LDL-C) were detected. Results Compared with before treatment in the same group, carotid artery IMT and plaque score decreased, levels of TC, TG, LDL-C, FPG, and HbAlc were reduced, PSV, EDV and PI increased, and VRI decreased in both two groups after treatment, with statisti- cal significance (P <0. 05). More obvious effects were shown in decreasing carotid artery IMT, plaque score, PA, and unstable plaque detection rate, reducing levels of TC, LDL-C and VRI, and increasing HDL-C, PSV, and EDV in the observation group, with statistical difference as compared with the control group (P <0. 05). After treatment the reconstruction rate and negative remodeling increased in the control group, with statistical difference as compared with before treatment (P <0. 05). Compared with the control group after treatment, the negative remodeling increased more in the observation group after treatment (X2 =6. 4615, P <0. 05). Conclusion NC could alleviate the carotid artery IMT, reduce and stabilize the plaque, improve blood flow parameters, and delay vascular reconstruction for treating T2DM patients with subclinical vascular disease.

Shenzhu Tiaopi granule combined with lifestyle intervention therapy for impaired glucose tolerance: a randomized controlled trial.

OBJECTIVE: The purpose of the study was to evaluate the clinical effects of the Shenzhu Tiaopi granule (SZTP) combined with a lifestyle intervention in patients with impaired glucose tolerance (IGT), who also had a spleen deficiency and damp overabundance syndrome (SDDOS). METHODS: After a one-month washout period, a total of 514 patients were randomly assigned to the control (lifestyle intervention) and experimental (SZTP plus lifestyle intervention) groups, with 257 patients in each group. Patients in the control group received the lifestyle intervention (diet and exercise) for 12 months, while the patients in the experimental group were treated with SZTP plus the lifestyle intervention for 12 months. The Traditional Chinese Medicinal (TCM) symptom scores were observed in each group before and after treatment; the conversion rates from IGT to diabetes mellitus (DM) were also measured. RESULTS: Following 12 months of treatment, the conversion rate from IGT to DM in the experimental group was significantly lower than in the control group (8.52% vs. 15.28%, P<0.05). A significantly higher number of patients with IGT reverted to normal blood glucose levels in the experimental group than in the control group (42.15% vs. 32.87%, P<0.05). In addition, after following the treatment for 12 months, the TCM symptoms of patients in the experimental group were markedly alleviated, as compared to the control group (P<0.01). CONCLUSION: The combination of SZTP and lifestyle intervention showed a reduction in the conversion from IGT to DM, and an increase in the conversion from IGT to normal blood glucose levels.
