Abstract
Type 2 diabetes mellitus (T2DM) has been the most prevalent disease and has become a serious public health threat worldwide. Gynura bicolor (Willd.) DC. (GB) contains a variety of nutrients and possesses numerous activities, which might benefit those with diabetes. The current study aimed to confirm the improvement of metabolic disorders and explore the potential mechanism of GB in high fat diet-fed (HFD) and streptozotocin (STZ)-induced T2DM mice. The aboveground sample of GB was extracted with alcohol, and identified by highperformance liquid chromatography (HPLC) and liquid chromatography-Mass Spectrometry/Mass Spectrometry (LC-MS/MS) analysis. HFD and STZ-induced T2DM mice were administrated with GB extract. Biochemical and histopathologic examinations were conducted, and metabolomics evaluation was performed in serum and urine. GB significantly reduced body weight and liver weight, reversed hyperlipidemia, hyperglycemia, insulin resistance, oxidative stress and inflammation, improved hepatic histopathological changes and lipid deposition and mitigated liver injury in T2DM mice. Serum and urine metabolomics demonstrated a variety of significantly disturbed metabolites in T2DM and these changes were reversed after GB administration, including 13S-hydroxyoctadecadienoic acid, arachidonic acid, L-Valine and so on. According to the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, the overlapping enriched pathways in the normal control group and GB group were identified, including linoleic acid metabolism, PPAR signaling pathway, protein digestion and absorption, biosynthesis of amino acids and so on. This study demonstrates that the ethanol extract of GB remarkably attenuates metabolic disorders and maintains the dynamic balance of metabolites in T2DM, providing a scientific basis for GB in the treatment of T2DM and metabolism diseases.

Kaneto H, Baxter M, Takahashi Y, Terauchi Y. Simultaneous Versus Sequential Initiation of Lixisenatide and Basal Insulin for Type 2 Diabetes: Subgroup Analysis of a Japanese Post-Marketing Surveillance Study of Lixisenatide (PRANDIAL). Adv Ther 2022; 39:5453-5473. [PMID: 36207508 PMCID: PMC9618543 DOI: 10.1007/s12325-022-02311-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 08/25/2022] [Indexed: 01/30/2023]
Abstract
INTRODUCTION We aimed to assess the efficacy and safety of lixisenatide and basal insulin (BI) according to timing of treatment initiation, treatment compliance, and number of concomitant daily injections in Japanese individuals with type 2 diabetes (T2D). METHODS Each substudy analyzed subgroup data from the 3-year post-marketing surveillance PRANDIAL study. Endpoints included glycated hemoglobin (HbA1c), postprandial glucose, treatment response (HbA1c < 7.0% at week 24 and 156), and safety. Changes in HbA1c levels were analyzed using paired t tests; between-group comparisons were made using analysis of variance (ANOVA). RESULTS Of 2679 participants, 46.5% initiated BI before lixisenatide, 12.0% the same day, 2.7% between 1 and 90 days, and 2.8% at 91 or more days after lixisenatide; 36.0% did not receive BI. Overall, 85.4% of patients were compliant with lixisenatide treatment. The majority of patients (52.4%) received two injections/day (one was lixisenatide). Compared with other subgroups taking BI and lixisenatide, the subgroup starting them simultaneously had a mean change in HbA1c of - 0.69% [8 mmol/mol] (vs + 0.07% [0.8 mmol/mol] to - 0.79% [9 mmol/mol]) and numerically higher treatment response (21.0% vs 8.3-18.7%), but more hypoglycemia (8.1% vs 2.3-2.8%). CONCLUSIONS Japanese people with T2D achieved better glycemic control by simultaneous as opposed to sequential initiation of lixisenatide and BI.
