Background: Insulin antibodies (IAs) affect blood glucose control in patients receiving insulin therapy.

Aim: To investigate the relationship between different hypoglycemic treatments and IAs in patients with type 2 diabetes mellitus (T2DM).

Methods: This cross-sectional, retrospective study included 1863 patients with T2DM who were receiving exogenous insulin therapy.

Background And Aims: To compare the effects of real-time and retrospective flash glucose monitoring (FGM) on daily glycemic control and lifestyle in patients with type 2 diabetes on premix insulin therapy.

Methods And Results: A total of 172 patients using premix insulin, with HbA1c ≥ 7.0% (56 mmol/mol), or the time below the target (TBR) ≥ 4%, or the coefficient of variation (CV) ≥36% during the screening period, were randomly assigned to retrospective FGM (n = 89) or real-time FGM group (n = 83).

Introduction: Prevalence of sarcopenia has increased in patients with type 2 diabetes. The influence of glucose-lowering drugs on muscles in these patients remains unclear. We aimed to investigate the association between muscle mass/function and glucose-lowering drugs.

Background: This study is aimed at investigating whether dapagliflozin adjunct to insulin therapy further improves glycemic control compared to insulin therapy alone in patients with newly diagnosed type 2 diabetes (T2D).

Methods: This single-centre, randomized, controlled, open-labeled trial recruited newly diagnosed T2D patients. Subjects were randomized 1 : 1 to the dapagliflozin add-on to continuous subcutaneous insulin infusion (CSII) group (DAPA) or the CSII therapy group for 5 weeks.

Rationale: Dumping syndrome is a frequent and potentially severe complication after gastric surgery. Beinaglutide, a recombinant human glucagon-like peptide-1 (GLP-1) which shares 100% homology with human GLP-1(7-36), has never been reported in the treatment of dumping syndrome before.

Patient Concerns: The patient had undergone distal gastrectomy for gastric signet ring cell carcinoma 16 months ago.

Objective: To investigate the effect of metformin on testosterone levels in men with type 2 diabetes mellitus (T2DM).

Research Design And Methods: Seventy men with newly diagnosed drug-naive T2DM and HbA >9.0% (75 mmol/mol) were treated with intensive insulin pump therapy for 5 days to achieve glucose normalization.

Purpose: To observe the glycemic variation (GV) in uncontrolled Graves' disease (GD) patients with normal glucose metabolism measured by continuous glucose monitoring (CGM).

Methods: This was a single-center, open-label, observational study. From January 2017 to October 2017, 20 GD patients with normal glucose metabolism and 24 healthy control subjects were recruited.

To investigate whether metformin add-on to the continuous subcutaneous insulin infusion (Met + CSII) therapy leads to a significant reduction in insulin doses required by type 2 diabetes (T2D) patients to maintain glycemic control, and an improvement in glycemic variation (GV) compared to CSII only therapy. We analyzed data from our two randomized, controlled open-label trials. Newly diagnoses T2D patients were randomized assigned to receive either CSII therapy or Met + CSII therapy for 4 weeks.

Background:  The blood glucose point-of-care testing (POCT) system is important in the decision-making process involving patients suspected of having hypoglycemia. To investigate the real world of the POCT system being used in teaching hospitals in China.

Methods: The survey was conducted by Hisend Research Group from May 2015 to July 2015 in four teaching hospitals in China.

Hyperthyroidism causes impaired glucose tolerance, insulin resistance (IR) and insulin secretion. However, the glucose variability affected by thyroid dysfunction remains unclear. Glucose variability was assessed by continuous glucose monitoring (CGM) in a non-diabetic patient with Graves' disease (GD), to the best of our knowledge, for the first time.

To define the features of glycemic variations in drug naïve type 2 diabetic (T2D) patients with different HbA values using continuous glucose monitoring (CGM), a total of 195 drug naïve T2D patients were admitted. The subjects were divided into the following groups: lower HbA values (≤8%), moderate HbA values (>8% and ≤10%), and higher HbA values (>10%). The patients underwent oral glucose tolerance tests and were then subjected to 3-day CGM.

Background: To investigate whether saxagliptin add-on therapy to continuous subcutaneous insulin infusion (CSII) further improve blood glycemic control than CSII therapy in patients with newly diagnosed type 2 diabetes (T2D).

Methods: This was a single-center, randomized, control, open-labeled trial. Newly diagnosed T2D patients were recruited between February 2014 and December 2015.
