Efficacy and safety benefits of iGlarLixi versus insulin glargine 100 U/mL or lixisenatide in Asian Pacific people with suboptimally controlled type 2 diabetes on oral agents: The LixiLan-O-AP randomized controlled trial.

AIMS: To compare the efficacy and safety of iGlarLixi with insulin glargine 100 units/mL (iGlar) and lixisenatide (Lixi), in Asian Pacific people with suboptimally controlled type 2 diabetes (T2D) on metformin with or without a second oral antihyperglycaemic drug (OAD). MATERIALS AND METHODS: LixiLan-O-AP (NCT03798054) was a 24-week multicentre study in adults (n = 878, mean age 56.0 years, mean body mass index 26.0 kg/m2 ) with glycated haemoglobin (HbA1c) levels ≥53 mmol/mol (7%) and ≤97 mmol/mol (11%) on OAD(s), randomized (2:2:1) to open-label once-daily iGlarLixi, iGlar or Lixi while on continued metformin ± sodium-glucose cotransporter-2 inhibitors. The primary efficacy endpoint was change in HbA1c. RESULTS: After 24 weeks, greater reductions in HbA1c from baseline (67 mmol/mol; 8.3%) were seen with iGlarLixi (-21 mmol/mol; -1.9%) compared with iGlar (-16 mmol/mol; -1.4%; P < 0.0001) and Lixi (-10 mmol/mol; -0.9%; P < 0.0001). Greater proportions of participants achieved HbA1c <53 mmol/mol (<7%) with iGlarLixi versus iGlar or Lixi (79%, 60% and 30%, respectively), overall and as composite endpoints including weight and hypoglycaemia. iGlarLixi improved 2-hour postprandial glucose versus iGlar and Lixi and mitigated the weight gain seen with iGlar (least squares mean difference -1.1 kg; P < 0.0001). Documented ≤3.9 mmol/L (≤70 mg/dL) hypoglycaemia was similar between iGlarLixi and iGlar (both 3.38 events per participant-year). The incidence rates of nausea and vomiting were lower with iGlarLixi (14% and 6%) than Lixi (21% and 11%). CONCLUSIONS: iGlarLixi achieved significant HbA1c reductions, to near-normoglycaemic levels, compared with iGlar or Lixi, with no meaningful additional risk of hypoglycaemia and mitigated body weight gain versus iGlar, with fewer gastrointestinal adverse events versus Lixi. iGlarLixi with specifically adapted ratios may provide an efficacious and well-tolerated treatment option for Asian Pacific people with T2D.

Impact of variants of the EXT2 gene on Type 2 diabetes and its related traits in the Chinese han population.

PURPOSE/AIM OF THE STUDY: Exostosin 2 (EXT2) is involved in early pancreatic development and the regulation of insulin synthesis. In this study, we aim to evaluate the contribution of EXT2 to the genetic pathogenesis of type 2 diabetes and its related traits in the Chinese population. MATERIALS AND METHODS: A case-control study in a Chinese Han population was conducted that included 4766 patients with type 2 diabetes and 4596 control subjects from 14 different regions of China. Three single nucleotide polymorphism (SNP), rs3740878, rs11037909 and rs1113132, in the EXT2 gene were genotyped using the Illumina GoldenGate Genotyping assay. RESULTS: After adjusting for sex, age and body mass index, logistic regression analysis revealed that the EXT2 gene had no association with type 2 diabetes using an additive genetic model [rs3740878 (Odds Ratio (OR) = 0.996, 95% confidence interval (CI) 0.928-1.069, p = 0.910), rs11037909 (OR = 1.003, 95%CI 0.933-1.078, p = 0.931), and rs1113132 (OR = 0.993, 95% CI 0.925-1.065, p = 0.842)]. None of these SNPs were associated with beta cell function as determined using the baseline disposition index, early phase insulin secretion and Oral Glucose Tolerance Test (OGTT) total disposition index. CONCLUSIONS: Our study suggests that the EXT2 gene might not have a major role in the development of type 2 diabetes in the Chinese population.

Successful management of a multiple endocrine neoplasia type 1-associated thymic neuroendocrine neoplasms with acute chest pain as initial symptom: A rare case report.

Key Clinical Message: Acute chest pain can be the first manifestation of multiple endocrine neoplasia type 1(MEN1)-associated thymic neuroendocrine neoplasms (NEN). Comprehensive treatment may be an effective strategy for MEN1-associated NEN. Abstract: Multiple endocrine neoplasia type 1(MEN1)-associated thymic neuroendocrine neoplasms (NEN) is caused by the mutation of tumor suppressor MEN1 gene. Patients with MEN1-associated NEN initially presenting with acute chest pain are very rare. In the manuscript, we reported a case of a 45-year-old man who developed MEN1-associated NEN with acute chest pain as initial symptom. Thoracoscopic thymotomy was performed and thymic NEN was successfully removed. Genetic test showed a germline mutation of MEN1 gene in this patient. Immunohistochemical staining exhibited Syn(+), CgA(+), INSM1(+), CD56(+) and Ki67-positive cells (2%) in MEN1-associated NEN. Further evaluation unveiled MEN1-associated benign tumors including digestive NEN and pituitary gland adenoma. The 99mTc-HYNIC-TOC scintigraphy showed that focally increased radioactivity in the mid-upper abdomen. This patient was administered with 50Gy/25F of radiation dose to treat the postoperative lesions. Subsequently, sandostatin LAR (30 mg per week) was used as systemic therapy. He had no recurrence or metastasis for 6-month follow-up. Thus, acute chest pain can be the first manifestation of MEN1-associated NEN, and comprehensive treatment including surgery, radiation and systemic treatment may be an effective strategy for MEN1-associated NEN.

Diversities of Mechanism in Patients with VHL Syndrome and diabetes: A Report of Two Cases and Literature Review.

Background: Von Hippel-Lindau (VHL) syndrome is characterized by tumorous lesions affecting multiple organs. Pancreatic involvement in VHL syndrome can present as endocrine tumors and pancreatic cysts, which can interfere with both exocrine and endocrine functions of the pancreas. Diabetes is an uncommon complication of VHL syndrome. Purpose: This study aims to summarize the various mechanisms of diabetes in VHL syndrome by reporting two cases and conducting a literature review. Methods: We analyzed the clinical and imaging data of two patients with VHL syndrome and diabetes. Additionally, we reviewed the existing literature to explore the clinical diversities and management strategies for VHL syndrome complicated with diabetes. Results: The first patient presented with liver metastasis of pancreatic neuroendocrine tumor and multiple pheochromocytoma. After surgery, the patient's diabetic control improved, as evidenced by a significant reduction in insulin dosage. This indicates a potential insulin resistance due to elevated metanephrine levels prior to surgery and partial insulin deficiency caused by distal pancreatectomy. The second patient had multiple hemangioblastomas, as well as multiple pancreatic cysts and positive pancreatic islet autoantibodies. Diabetes in this case may be attributed to pancreatic lesions and the coexistence of autoimmune insulitis. A literature review of other patients with VHL combined with diabetes revealed multiple mechanisms, including increased catecholamine levels, pancreatic lesions, surgical removal of pancreatic tissue, endocrine treatment, and possibly the coexistence of autoimmune insulitis. Conclusion: VHL syndrome complicated with diabetes involves diverse mechanisms.

Serum lipids and lipoproteins in Chinese men and women.

BACKGROUND: Because of rapid change in lifestyle risk factors, cardiovascular disease has become the leading cause of death in China. We sought to estimate the national levels of serum lipids and lipoproteins among the Chinese adult population. METHODS AND RESULTS: We conducted a cross-sectional study in a nationally representative sample of 46 239 adults aged ≥20 years. Fasting serum total, high-density lipoprotein, and low-density lipoprotein cholesterol and triglycerides were measured by standard methods. The age-standardized estimates of total, high-density lipoprotein, and low-density lipoprotein cholesterol and triglycerides were 4.72 (95% confidence interval, 4.70-4.73), 1.30 (1.29-1.30), 2.68 (2.67-2.70), and 1.57 (1.55-1.58) mmol/L, respectively, in the Chinese adult population. In addition, 22.5% (21.8-23.3%) or 220.4 million (212.1-228.8) Chinese adults had borderline high total cholesterol (5.18-6.21 mmol/L), and 9.0% (8.5-9.5%) or 88.1 million (83.4-92.8) had high total cholesterol (≥6.22 mmol/L). The population estimates for borderline high (3.37-4.13 mmol/L), high (4.14-4.91 mmol/L), and very high (≥4.92 mmol/L) low-density lipoprotein cholesterol were 13.9% (13.3-14.5%) or 133.5 million (127.0-140.1), 3.5% (3.3-3.8%) or 33.8 million (31.2-36.5), and 3.0% (2.8-3.3%) or 29.0 million (26.3-31.8) persons, respectively. In addition, 22.3% (21.6-23.1%) or 214.9 million (207.0-222.8) persons had low high-density lipoprotein cholesterol (<1.04 mmol/L). The awareness, treatment, and control of borderline high or high total cholesterol were 11.0%, 5.1%, and 2.8%, respectively, in the Chinese adult population. CONCLUSIONS: Serum total and low-density lipoprotein cholesterol levels were high and increasing in the Chinese population. Without effective intervention, atherosclerotic cardiovascular diseases may soar in the near future in China.

Prevalence of diabetes among men and women in China.

BACKGROUND: Because of the rapid change in lifestyle in China, there is concern that diabetes may become epidemic. We conducted a national study from June 2007 through May 2008 to estimate the prevalence of diabetes among Chinese adults. METHODS: A nationally representative sample of 46,239 adults, 20 years of age or older, from 14 provinces and municipalities participated in the study. After an overnight fast, participants underwent an oral glucose-tolerance test, and fasting and 2-hour glucose levels were measured to identify undiagnosed diabetes and prediabetes (i.e., impaired fasting glucose or impaired glucose tolerance). Previously diagnosed diabetes was determined on the basis of self-report. RESULTS: The age-standardized prevalences of total diabetes (which included both previously diagnosed diabetes and previously undiagnosed diabetes) and prediabetes were 9.7% (10.6% among men and 8.8% among women) and 15.5% (16.1% among men and 14.9% among women), respectively, accounting for 92.4 million adults with diabetes (50.2 million men and 42.2 million women) and 148.2 million adults with prediabetes (76.1 million men and 72.1 million women). The prevalence of diabetes increased with increasing age (3.2%, 11.5%, and 20.4% among persons who were 20 to 39, 40 to 59, and > or = 60 years of age, respectively) and with increasing weight (4.5%, 7.6%, 12.8%, and 18.5% among persons with a body-mass index [the weight in kilograms divided by the square of the height in meters] of < 18.5, 18.5 to 24.9, 25.0 to 29.9, and > or = 30.0, respectively). The prevalence of diabetes was higher among urban residents than among rural residents (11.4% vs. 8.2%). The prevalence of isolated impaired glucose tolerance was higher than that of isolated impaired fasting glucose (11.0% vs. 3.2% among men and 10.9% vs. 2.2% among women). CONCLUSIONS: These results indicate that diabetes has become a major public health problem in China and that strategies aimed at the prevention and treatment of diabetes are needed.

How do resource dependence and technological progress affect carbon emissions reduction effect of industrial structure transformation? Empirical research based on the rebound effect in China.

Under the guidance of carbon peak and carbon neutral targets, the industrial structure transformation is vital for carbon emissions reduction in China. However, there is a rebound effect of carbon emissions during the industrial structure transformation. Resource dependence and technological progress have significant impacts on industrial structure transformation and its carbon reduction effect. This paper explores how industrial structure transformation under resource dependence causes the rebound effect from a technological progress perspective. The key results indicate that (1) resource dependence distorts the carbon emissions reduction effect of industrial structure transformation; (2) with the development of technology, the industrial structure upgrading under resource dependence could cause an increase on carbon emissions at the beginning, but the increase would be weakened subsequently, displaying a two-stage feature; (3) the industrial structure rationalization under resource dependence reduces carbon emissions at first, but the reduction would be weakened as the technology develops, then industrial structure's rationalization shows an insignificant impact on carbon emissions, and finally reduces carbon emissions again, presenting a four-stage characteristic; (4) environmental protection technology can correct the distortion effect of resource dependence on the industrial structure rationalization and amplify the industrial structure rationalization's reduction effects on carbon emissions; (5) with the development of energy-saving technology, industrial structure rationalization has a paradoxical impact on carbon emissions, the industrial structure rationalization first reduces, then increases, and finally reduces carbon emissions, indicating an inverted "N" relationship. Finally, policy recommendations for carbon emissions reduction are proposed from the perspective of industrial structure transformation and technological progress.

Exploring the nexus of green finance and renewable energy consumption: unraveling synergistic effects and spatial spillovers.

As China transitions towards a green and low-carbon energy system, it is crucial to have the support of green finance. In this study, we explore the effects of synergy and spatial spillovers in the development of green finance and the consumption of renewable energy. By taking a synergistic perspective, we aim to provide new insights for energy structure reform. We use a spatial simultaneous equations model in combination with a three-stage generalized spatial least squares approach, our findings are the following: firstly, there is a positive synergy between the development of green finance and the consumption of renewable energy. Secondly, there are positive spatial spillovers in the development of green finance and the consumption of renewable energy, but the regional interaction effects of green finance development on renewable energy consumption are negative. Furthermore, we observe that the impact of renewable energy consumption on green finance development has been increasing since 2013. However, the reverse relationship is not true, indicating that the renewable energy industry has stabilized and is gaining appeal in financial markets. Our study highlights that the development of green finance can promote an increase in renewable energy consumption through the facilitation of economic growth, green technology innovation, and the upgrading of the industrial structure. We emphasize the importance of regional and industrial coordination to create synergy between green finance development and renewable energy consumption.

Decreased programmed cell death ligand 2-positive monocytic myeloid-derived suppressor cells and programmed cell death protein 1-positive T-regulatory cells in patients with type 2 diabetes: implications for immunopathogenesis.

Objectives: The activation of immune cells plays a significant role in the progression of type 2 diabetes. This study aimed to investigate the potential role of myeloid-derived suppressor cells (MDSCs) and T-regulatory cells (Tregs) in type 2 diabetes. Methods: A total of 61 patients diagnosed with type 2 diabetes were recruited. Clinical characteristics were reviewed and peripheral blood samples were collected. We calculated the percentage of different cells. Frequencies of MDSC subsets refered to the percentage of G-MDSCs (CD15+CD33+CD11b+CD14-HLA-DR-/low) in CD45 positive cells and the percentage of M-MDSCs (CD14+CD15-CD11b+CD33+HLA-DR-/low) in lymphocytes plus monocytes. Results: Frequencies of programmed cell death ligand 1-positive granulocytic MDSCs (PD-L1+ G-MDSCs), programmed cell death ligand 2-positive monocytic MDSCs (PD-L2+ M-MDSCs), PD-L2+ G-MDSC, and programmed cell death protein 1-positive Tregs (PD-1+Tregs) were decreased in patients with type 2 diabetes. The frequency of PD-1+ Tregs was positively related to PD-L2+ M-MDSCs (r= 0.357, P = 0.009) and negatively related to HbA1c (r = -0.265, P = 0.042), fasting insulin level (r = -0.260, P = 0.047), and waist circumference (r = -0.373, P = 0.005). Conclusions: Decreased PD-L2+ M-MDSCs and PD-1+ Tregs may promote effector T cell activation, leading to chronic low-grade inflammation in type 2 diabetes. These findings highlight the contribution of MDSCs and Tregs to the immunopathogenesis of type 2 diabetes and suggest their potential as targets for new therapeutic approaches.

Pituitary stalk interruption syndrome and liver cirrhosis associated with diabetes and an inactivating KCNJ11 gene mutation: a case report and literature review.

Background: Pituitary stalk interruption syndrome (PSIS) is a congenital disease commonly found in patients with combined pituitary hormone deficiency (CPHD). Most PSIS patients manifest growth retardation and delayed puberty. We report a rare case of PSIS with tall stature, liver cirrhosis and diabetes, possibly caused by an inactivating KCNJ11 gene mutation. Case presentation: A 37-year-old female patient initially presented with liver cirrhosis and diabetes, without any secondary sexual characteristics. Endocrine investigation indicated CPHD. Small anterior pituitary, invisible pituitary stalk and no eutopic posterior lobe hypersignal in the sella turcica viewed in magnetic resonance imaging (MRI) confirmed the diagnosis of PSIS. Despite receiving no growth hormone or sex hormone therapy, she reached a final height of 186 cm. Liver histopathology revealed nonalcoholic fatty cirrhosis. Genetic testing identified a heterozygous p.Arg301Cys mutation in the KCNJ11 gene. Conclusion: This is a rare case of PSIS with liver cirrhosis and diabetes associated with an inactivating KCNJ11 gene mutation. It's supposed that early hyperinsulinism caused by the KCNJ11 gene mutation, as well as delayed epiphyseal closure due to estrogen deficiency, contributed to the patient's exceptionally tall stature. Untreated growth hormone deficiency (GHD) resulted in increased visceral fat, leading to nonalcoholic fatty liver disease (NAFLD) and cirrhosis. The decline in ß cell function with age, combined with NAFLD, may have played a role in the development of diabetes.

The concordance and discordance of diabetic kidney disease and retinopathy in patients with type 2 diabetes mellitus: A cross-sectional study of 26,809 patients from 5 primary hospitals in China.

Introduction: Diabetic kidney disease (DKD) and diabetic retinopathy (DR) share similar pathophysiological mechanisms. However, signs of DKD may be present at diagnosis of diabetes without retinopathy. Risk factors for the development of DKD and DR may not be identical. Methods: This study aimed to evaluate the concordance and discordance between DKD and DR by investigating the distribution of DKD and DR in patients with type 2 diabetes mellitus from 5 Chinese cities. A total of 26,809 patients were involved in this study. The clinical characteristics were compared among patients based on the presence of DKD and DR. Logistic regression models were used to analyze the independent risk factors of DKD and DR. Results: The prevalence of DKD and DR was 32.3% and 34.6%, respectively. Among eligible patients, 1,752 patients without DR had an increased urinary albumin-to-creatinine ratio (ACR) or reduced estimated glomerular filtration rate (eGFR), and 1,483 patients with DR had no DKD. The positive predictive value of DR for DKD was 47.4% and negative predictive value was 67.1%. Elder age, male gender, a longer duration of disease, higher values of waist circumference and HbA1c were associated with both DR and DKD. A lower educational level was associated with DR. Higher BP and TG would predict increased prevalence of DKD. Conclusions: DKD and DR shared many risk factors, but a significant discordance was present in patients with type 2 diabetes mellitus. DKD was more strongly associated with blood pressure and triglycerides than DR.

Effects of transplantation of umbilical cord blood mononuclear cells into the scrotum on sexual function in elderly mice.

Aim: This study investigated the effect of allografting umbilical cord blood mononuclear cells (UCBMCs) into the scrotum on sexual function in male elderly mice. Methods: UCBMCs were injected once into the scrotal sheath cavity of elderly mice. Results: The transplanted UCBMCs survived in the scrotal sheath cavity for 1 month. The mice had significantly increased blood testosterone concentrations, cyclic guanosine monophosphate (cGMP) levels and total nitric oxide synthase (T-NOS) activity in the corpus cavernosum and an increase in the number of mouse matings within 30 min (all p = 0.000). Conclusion: Scrotum-implanted UCBMCs improve the sexual function of male elderly mice through testosterone production and the NOS/cGMP pathway, which may provide an innovative transplantation approach for the treatment of erectile dysfunction.

COVID-19 vaccine coverage, safety, and perceptions among patients with diabetes mellitus in China: a cross-sectional study.

Aims: Diabetes mellitus (DM), one of the most common chronic diseases in China, is a risk factor for SARS-COV-2 infection and poor prognosis of COVID-19. The COVID-19 vaccine is one of the key measures to control the pandemic. However, the actual coverage of COVID-19 vaccination and associated factors remain unclear among DM patients in China. We conducted this study to investigate the COVID-19 vaccine coverage, safety, and perceptions among patients with DM in China. Methods: A cross-sectional study of a sample of 2200 DM patients from 180 tertiary hospitals in China was performed using a questionnaire developed through the Wen Juan Xing survey platform to collect information regarding their coverage, safety, and perceptions of COVID-19 vaccination. A multinomial logistic regression analysis model was performed to determine any independent relationships with COVID-19 vaccination behavior among DM patients. Results: In total, 1929 (87.7%) DM patients have received at least one dose COVID-19 vaccine, and 271 (12.3%) DM patients were unvaccinated. In addition, 65.2% (n = 1434) were booster vaccinated against COVID-19, while 16.2% (n = 357) were only fully vaccinated and 6.3% (n = 138) were only partially vaccinated. The prevalence of adverse effects after the first dose of vaccine, the second dose of vaccine, and the third dose of vaccine were 6.0%, 6.0%, and 4.3% respectively. Multinomial logistic regression analysis showed that DM patients complicated with immune and inflammatory diseases (partially vaccinated: OR = 0.12; fully vaccinated: OR = 0.11; booster vaccinated: OR = 0.28), diabetic nephropathy (partially vaccinated: OR = 0.23; fully vaccinated: OR = 0.50; booster vaccinated: OR = 0.30), and perceptions on the safety of COVID-19 vaccine (partially vaccinated: OR = 0.44; fully vaccinated: OR = 0.48; booster vaccinated: OR = 0.45) were all associated with the three of vaccination status. Conclusion: This study showed that higher proportion of COVID-19 vaccine coverage among patients with DM in China. The concern about the safety of the COVID-19 vaccine affected the vaccine behavior in patients with DM. The COVID-19 vaccine was relatively safe for DM patients due to all side effects were self-limiting.

Denosumab biosimilar (LY06006) in Chinese postmenopausal osteoporotic women: A randomized, double-blind, placebo-controlled, multicenter phase III study.

Objectives: This study assessed the efficacy, safety, pharmacokinetics (PK), and immunogenicity profiles of a denosumab biosimilar (LY06006) in Chinese postmenopausal osteoporotic women with a high risk of fracture. Methods: In this multicenter, randomized, double-blind, placebo-controlled, phase 3 trial, 448 postmenopausal women aged 50-85 years with osteoporosis were enrolled at 49 centers in China and were randomly assigned (3:1) to receive 60 â€‹mg of the denosumab biosimilar (LY06006) or placebo subcutaneously every 6 months for 1 year. Lumbar spine bone mineral density (BMD) change was the primary endpoint. Results: Of the 448 randomized patients, 409 (LY06006, n â€‹= â€‹311; placebo, n â€‹= â€‹98) completed the study. All 448 (100.0%) subjects were included in the intent-to-treat (ITT) trial, 427 (95.3%) were included in the full analysis set (FAS), 408 (91.1%) were included in the per protocol set (PPS), 446 (99.6%) were included in the safety set (SS), and 336 (75.0%) were included in the pharmacokinetics concentration set (PKCs). For the primary endpoint, a 4.71% (95% CI, 3.81%, 5.60%) treatment difference in percent change in lumbar spine BMD from baseline to month 12 was observed in the LY06006 group compared with the placebo group (P â€‹< â€‹0.0001). For the secondary endpoints, LY06006 was associated with increased lumbar spine BMD levels measured at month 6, BMD levels at the femoral neck, total hip, and trochanter measured at months 6 and 12 and reduced serum C-terminal telopeptide of type 1 collagen (CTX) and procollagen type 1 â€‹N-peptide (P1NP) levels at months 1, 6, and 12. Safety analysis was based on the safety analysis set (SS), and 264 (78.6%) subjects in the LY06006 group and 83 (75.5%) in the placebo group experienced adverse events (AEs). Most events were mild or moderate and not related to the study drugs. Conclusion: In postmenopausal women with a high risk of fracture, LY06006 increased the BMD and decreased bone resorption; thus, LY06006 might be an effective treatment for osteoporosis. LY06006 was generally safe and well tolerated without unexpected adverse reactions, similar to the reference drug Prolia®. The characteristics of effectiveness and safety were similar to those reported in previous studies. The translational potential of this article: In this multi-center, randomized, double-blind, placebo-controlled phase 3 study, LY06006 showed substantially efficacy to increase BMD and well tolerance without unexpected adverse reactions, which is comparable to the reference drug Prolia ®. The presented results are encouraging and can offer some valuable evidence for the clinical practice.

[Analysis of medication with hypertension by different glucose tolerance status].

OBJECTIVE: To analyze the combination of hypertension and the use of antihypertensive drugs by different glucose tolerance status. METHODS: Matched case-control design was used to sample the subjects from the population for the prevalence of diabetes mellitus and metabolism syndrome from 2007 to 2008. There were 3 groups including normal glucose tolerance (NGT, n = 2124), impaired glucose regulation (IGR, n = 2162) and diabetes (DM, n = 2470). The matched factors were location, age and gender. All subjects were interviewed to describe the hypertension and antihypertensive drugs of these conditions. RESULTS: After adjusting for age, gender and location, the combination of hypertension in IGR and DM groups was higher than NGT (28.3%, 40.2% and 19.9%) and OR was 1.29 (1.08 - 1.53) and 1.99 (1.67 - 2.37) respectively. The percent of treatment, prescription compliance and the surveillance of hypertension in total subjects were 48.6%, 79.3% and 62.5%. And no difference was observed among 3 groups. The proportion of calcium channel blocker of DM groups was higher than NGT group. The uses of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blocker (ARB) showed no difference among 3 groups. CONCLUSIONS: The combination of hypertension is higher in IGR and DM groups than that in NGT group. And the treatment rate of hypertension remains low. ACEI and ARB are under-utilized in IGR and DM groups.

[Ageing related changes of insulin secretion and insulin sensitivity among normal glucose tolerance individuals in China].

OBJECTIVE: To explore the aging-related changes of insulin secretion and insulin sensitivity among normal glucose tolerance (NGT) individuals in China. METHODS: A total of 34 293 individuals were recruited. All of them were described as NGT by 75 g oral glucose tolerance test (75 g OGTT) according to the diagnostic criterion of WHO, 1999. HOMA-ß, ΔI(30)/ΔG(30), InsAuc30/GluAuc30, InsAuc120/GluAuc120 were calculated to estimate insulin secretion; HOMA-IR and Matsuda index measured to estimate insulin sensitivity; Disposition index: DI(30) and DI(120) were used to estimate ß-cell function. RESULTS: HOMA-ß, ΔI(30)/ΔG(30), InsAuc30/GluAuc30 and InsAuc120/GluAuc120 were all lower in the elder group then the younger group (P trend < 0.05). The mean HOMA-ß dropped from 192 ± 16 (20 - 29 years) to 115 ± 7 (70 or elder) among men and from 162 ± 8 (20 - 29 years) to 120 ± 12 (70 or elder) among women. The mean ΔI(30)/ΔG(30) dropped from 20.0 ± 2.0 (20 - 29 years) to 8.6 ± 0.6 (70 or elder) among men and from 22.4 ± 1.6 (20 - 29 years) to 12.5 ± 1.7 (70 or elder) among women. The above index were negatively correlated with age in univariate linear regression (P < 0.05), the results among men and overall still existed after adjusted for BMI and waist circumference in multivariate linear regression, while the relation between HOMA-ß and age disappeared among women. Matsuda Index was positively correlated with age (ß = 0.02, P = 0.001) and HOMA-IR were negatively correlated with age (ß = -0.01, P = 0.001) among men even after adjusted for BMI and waist circumference and the above correlation between Matsuda Index/HOMA-IR and ageing was not significant until adjusted for BMI and waist circumference in multivariate linear regression. Among women HOMA-IR (ß = -0.01, P = 0.000), Matsuda index (ß = 0.03, P = 0.000). DI(30) and DI(120) were negatively correlated with age in both univariate and multivariate linear regression. CONCLUSIONS: The basal, postchallenge insulin secretion and postchallenge islet compensatory function decreases with ageing, while insulin sensitivity does not deteriorate with ageing and its related change of body composition and weight gain.

Euglycaemic Ketoacidosis Due to Extremely Low-Calorie Intake and Dehydration After Laparoscopic Sleeve Gastrectomy in a Patient with Type 2 Diabetes.

Background: Bariatric surgery is an effective therapy for type 2 diabetes mellitus (T2DM) and obesity. Euglycaemic ketoacidosis (EKA) has been reported in patients taking sodium-glucose cotransporter 2 (SGLT2) inhibitors after bariatric surgery. Cases of T2DM complicated with EKA without SGLT2 inhibitors after bariatric surgery are rarely reported. Purpose: To present a case report of a T2DM patient (without SGLT2 inhibitor use) who developed EKA soon after laparoscopic sleeve gastrectomy. Methods: Clinical records and interviews were used. Results: A 35-year-old female patient was diagnosed with T2DM and obesity. The patient underwent laparoscopic sleeve gastrectomy to lose weight and control her blood glucose levels. Her daily fluid intake was 800-1000 mL, and her daily caloric intake was less than 500 kcal during the first days after the surgery. She was prescribed degludec insulin, metformin and dulaglutide and her blood sugar was lower than 13.9 mmol/L. On postoperative Day 6, the patient complained of fatigue and vomiting. Blood gas analysis and urine analysis supported the diagnosis of ketoacidosis. Fluid resuscitation, insulin and glucose were administered to the patient immediately. On postoperative Day 8, the patient recovered without any symptoms. Conclusion: We report an extremely rare case of T2DM in which the patient developed EKA after laparoscopic sleeve gastrectomy owing to extremely low-calorie intake and dehydration. Physicians should be on alert for ketoacidosis in patients with T2DM after bariatric surgery with an euglycaemic status, even without the use of SGLT2 inhibitors or the presence of stresses, such as infection.Level V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Promoted Carbon Monoxide Sensing Performance of a Bi2Mn4O10-Based Mixed-Potential Sensor by Regulating Oxygen Vacancies.

The YSZ-based mixed-potential sensor has exhibited promising application prospects for in situ carbon monoxide (CO) monitoring owing to its excellent thermal stability. However, the way to further enhance the sensitivity and selectivity of the sensor remains challenging due to the limitation of the sensing material. In the present work, we proposed a strategy of introducing moderate oxygen vacancies in the transition metal oxide sensing material to enhance CO sensing performance. More importantly, the oxygen vacancies of the sensing electrode were regulated by adjusting the volatilization of the Bi element at different sintering temperatures. Meanwhile, the stable mullite structure and variable valency of Mn were also exploited to maintain the phase structure stability and charge balance brought by the loss of Bi. The relationship between CO sensing properties and the proportion of both Mn3+/Mn4+ and oxygen vacancies was elucidated from XPS and EIS measurements. By contrast, the 800 °C-sintered Bi2Mn4O10 possesses the highest oxygen vacancy content and thus exhibits preferable sensing performance including a lower detecting limit (10 ppm), swifter response/recovery processes, and enhanced CO sensitivity (-70.47 mV/decade operated at 450 °C) with satisfactory selectivity and stability, indicating a promising prospect for CO monitoring under exhaust environments.

The feasibility and efficacy of a community-based multifactorial intervention to improve the cardiovascular risk factor control among patients with type 2 diabetes: A 2-year cluster randomized trial.

TRIAL DESIGN: Our study is to investigate the feasibility and effectiveness of multiple cardiovascular factors intervention (MFI) in type 2 diabetes patients in China's primary care setting. METHODS: We performed a cluster randomized trial to compare the proportion of patients achieved the targets between usual care group (control, 9 sites, n = 868) and MFI group (8 sites, n = 739) among patients with type 2 diabetes in primary care setting. Logistic regression model with random effects was used to estimate the association of the effect of intervention and the proportion achieved the targets. RESULTS: At baseline, the end of 1 year, and 2 years follow-up, the proportion of patients achieved all 3 target goals (HbA1c < 7.0%, blood pressure < 130/80 mm Hg and low-density lipoprotein cholesterol < 2.6 mmol/L) were 5.7%, 5.9%, 5.7% in the control group and 5.9%, 10.6%, 12.3% in the MFI group. After adjusting sex, age, diabetes duration, body mass index, HbA1c, blood pressure, and low-density lipoprotein cholesterol at baseline, there was no difference between the 2 groups (OR (95% CI): 1.27 (0.38-4.27) and 1.86 (0.79-4.38) for the first year and second year, respectively). When stratified by payment method, the patients with medical insurance or public expenses had a higher proportion achieved target goals (6.9% vs 16.4%, OR (95% CI): 2.30 (1.04-5.08)) in the second year. CONCLUSIONS: The controlling of cardiovascular risk factor targets remains suboptimal among patients with type 2 diabetes in primary care setting. MFI in type 2 diabetes improved cardiovascular disease risk profile, especially in the patients with medical insurance.
