Prediabetes is an intermediate transition to hyperglycemia between normal blood glucose and diabetes, including impaired fasting glucose (IFG), impaired glucose tolerance (IGT)and the presence of a combination of the two.
At present, the prediabetes population in China is very large. Timely detection of this sub-health population and effective intervention are the key to prevent or delay diabetes and related complications. Basic research showed that Tangningtongluo had a good hypoglycemic effect on db/db diabetic mice and STZ induced diabetic rats, and could alleviate pancreatic islet destruction and insulin resistance to some extent.
In this study, the therapeutic effects of Tangningtongluo pian provided by Guizhou bailing Enterprise Group Pharmaceutical Co., Ltd on patients with prediabetes was evaluated clinically. A multi-center, randomized, double-blind, placebo-controlled clinical trial was designed to provide evidence-based medical evidence for Tangningtongluo pian in the treatment of prediabetes . In the design of this trial, the therapeutic effects and safety of Tangningtongluo pian in the treatment of prediabetes were evaluated with Tangningtongluo pian in the treatment group and placebo in the control group.
Prediabetes is an intermediate transition to hyperglycemia between normal blood glucose and diabetes, including impaired fasting glucose (IFG), impaired glucose tolerance (IGT)and the presence of a combination of the two.
At present, the prediabetes population in China is very large. Timely detection of this sub-health state and effective intervention are the key to prevent or delay diabetes and related complications. Prediabetes is mainly IGT, and its core pathophysiological basis is insulin resistance. The existing western medicine can improve insulin resistance to varying degrees, but it can not prevent diabetes. Tangning Tongluo is an in-hospital preparation of Guizhou bailing. It is used for diabetes caused by deficiency of Qi and Yin. The symptoms include thirst, drinking, overeating, polyuria, weight loss, shortness of breath, fatigue, hand, foot and heart heat and blurred vision; Type 2 diabetes and diabetic retinopathy see the above syndrome.Basic research showed that Tang Ning Tong Luo had a good hypoglycemic effect on db/db diabetic mice and STZ induced diabetic rats, and could alleviate pancreatic islet destruction and insulin resistance to some extent. In addition, the drug has a certain retarding effect on diabetic nephropathy animal models [renal function, renal pathology, urinary protein (3+ to 2+)] and fundus lesions, and also improves liver function and myocardial enzymes. Further mechanism studies show that Tangning Tongluo exerts its anti-inflammatory, hypoglycemic and obesity induced insulin resistance effects by up regulating the expression of sequence binding protein (SBP) 2 in macrophages ; In addition, mip1 was inhibited γ/ CCR1 axis improves in diabetic retinopathy.It is speculated that the drug may be effective for prediabetes In this study, the therapeutic effects of Tangningtongluo pian provided by Guizhou bailing Enterprise Group Pharmaceutical Co., Ltd on patients with prediabetes was evaluated clinically. A multi-center, randomized, double-blind, placebo-controlled clinical trial was designed to provide evidence-based medical evidence for Tangningtongluo pian in the treatment of prediabetes .

| Placebo group | Placebo Comparator | Placebo of Tangningtongluo tablet will be used in this arm. Patients should take medicine with warm water about 30min after meal. (2.0g/time, twice a day) According to the above usage and dosage, take 12 weeks continuously. After 12 weeks, the researcher decided whether the subjects entered the extended trial according to the wishes of the subjects, and continued to use the drug until 24 weeks. 2） Lifestyle intervention |
