1. Glucagon-like peptide-1 (7-36) amide (GLP-1) is a gut hormone released postprandially that stimulates insulin secretion, suppresses glucagon secretion and delays gastric emptying. The insulinotropic action of GLP-1 is more potent under hyperglycaemic conditions. Several published studies have indicated the therapeutic potential of subcutaneous GLP-1 in non-insulin-dependent (Type 2) diabetes mellitus. 2. We investigated whether subcutaneous GLP-1, at a dose shown to improve glycaemic control in early Type 2 diabetes, is insulinotropic at normal fasting glucose concentrations. A double-blind, randomized, crossover study of 10 healthy subjects injected with GLP-1 or saline subcutaneously after a 16 h fast was performed. The effect on cardiovascular parameters was also examined. 3. GLP-1 caused a near 5-fold rise in plasma insulin concentration. After treatment with GLP-1, circulating plasma glucose concentrations fell below the normal range in all subjects. One subject had symptoms of hypoglycaemia after GLP-1. A rise in pulse rate was found which correlated with the fall in plasma glucose concentration. An increase in blood pressure occurred with GLP-1 injection which was seen at the same time as the rise in plasma GLP-1 concentrations. 4. This study indicates that subcutaneous GLP-1 can override the normal homoeostatic mechanism maintaining fasting plasma glucose in man, and is also associated with an increase in blood pressure.

During the past two decades, the unequivocally recommended treatment method of Type 2 diabetes mellitus was insulin administration and intensification in the earliest possible stage of the diagnosis. This approach is not only unfounded but was never scientifically proven. Yet, it has been zealously advocated to medical professionals. In fact, a sound body of evidence disproves this long-standing treatment approach. This method is a cornerstone of, what we now know to be two great illusions of past century, namely, glucocentrism and intensification. Numerous recently published studies provide alarming data regarding serious side effects of blind intensification and insulin overdosing in T2DM. They raise major concerns and call for revision of the traditional approach. Since insulin is an integral and deeply rooted part of the intensification agenda of treating T2DM, it has now suffered a serious drawback. Alternatively, in this review authors present the novel Gravicentric (Energy) concept of T2DM acceptance and therapy. They offer a new classification of anti-diabetes drugs based on their energy effect and present their Gravicentric Algorithm for wide practical utilization. For that reason, the "ELEPHANT" abbreviation was found as a helpful reminder. Viewing T2DM as disease of energy balance together with anti – energy drugs implementation provide medical doctors an unique opportunity to transform T2DM from "slowly – progressive" disease to rapidly reversible condition, which it actually is.

Abstract Background: Several studies have shown the association of polymorphisms in the MTNR1B gene with type 2 diabetes mellitus (T2DM). However, there is no evidence about the impacts of its genetic polymorphism on the therapeutic efficacy of nateglinide. Therefore, this prospective case-control study was designed to investigate the effect of MTNR1B rs10830963 gene polymorphism on the therapeutic efficacy of nateglinide in treating T2DM. Methods: We genotyped 200 healthy subjects using the method of the high resolution of melting curve (HRM). A total of 60 T2DM patients were enrolled and given nateglinide (360 mg/d) for 8 weeks orally who had the same genotypes CYP2C9*1 and SLCO1B1 521TT respectively. The outcome was measured by collecting the venous blood samples before and at the 8th week of the treatment. Also, anthropometric measurements, glucose, and lipid metabolism were determined before and after the nateglinide treatment. Results: It was found that the risk G allelic frequency of MTNR1B rs10830963 was higher in T2DM patients when compared with the healthy subjects (P<0.05). 60 newly diagnosed patients with type 2 diabetes after completing the eight weeks treatment came for the follow-up visit and showed a reduction in fasting plasma glucose (FPG) levels with an increase in homeostasis model assessment for β cell HOMA-β in the carriers of genotype CG + GG at rs10830963, when compared with the wild-type CC (P <0.05). Conclusion: Thus, it was found that the MTNR1B rs10830963 polymorphism was associated with the therapeutic efficacy of nateglinide in T2DM patients. Also, the CC homozygotes had a better effect than G allele carriers. Trial registration: This study was registered in the Chinese Clinical Trial Register (No. ChiCTR-CCC13003536).
