ABSTRACT

OBJECTIVE: To analyse diabetes treatment, treatment change and self-management behaviours in association with 2-year glycaemic trajectories in patients with non-newly diagnosed type 2 diabetes mellitus in Chinese primary care. METHODS: This was an observational, multi-centre, longitudinal, retrospective cohort study. Clinical data of 4690 subjects were extracted from electronic medical records, including serial glycated haemoglobin A1c (HbA1c) measurements, antidiabetic medication records and compliance to exercise, diet, medications and self-monitoring of blood glucose (SMBG). Patterns of longitudinal HbA1c trajectories were identified using the percentage of HbA1c measurements <7.5% from the second available HbA1c measurement. Clinical relevance of the clusters was assessed through multivariable analysis. RESULTS: Approximately half of the participants demonstrated good glycaemic control; of these, 34.5% demonstrated stable, good control, and 13.7% demonstrated relatively good control. About 16.2% demonstrated moderate control, and 35.6% demonstrated poor control. From the good to poor control groups, the percentage of subjects treated with insulin at baseline and during the follow-up period increased gradually, while the percentage of subjects adhering to exercise, diet, medications and SMBG decreased gradually. Compared with baseline, the adherence to exercise, diet, medications and SMBG improved significantly. Approximately 50% and 26% of subjects in the two poorest control groups, respectively, experienced treatment changes. After multivariable adjustments, baseline HbA1c ≥7.5%, HbA1c change ≥-0.5% from baseline to visit 1, insulin treatment, treatment change, poor adherence to diet, exercise, SMBG during the follow-up period and HbA1c measurements <3 per year were significantly associated with poorer glycaemic control. CONCLUSION: We identified four longitudinal HbA1c trajectories in patients with non-newly diagnosed type 2 diabetes. Even if baseline HbA1c is suboptimal, aggressive treatment changes, good adherence during the follow-up period, ≥3 HbA1c measurements per year and reducing HbA1c levels to a certain extent by the first follow-up visit were important for good, stable, long-term glycaemic control.

ABSTRACT

AIMS: Our aim was to search for clinical predictors of good glycemic control in patients starting or intensifying oral hypoglycemic pharmacological therapy. METHODS: A multicenter, prospective cohort of 499 diabetic subjects was enrolled in this study: patients with newly diagnosed diabetes (NDM group) or poor glycemic control with oral antidiabetic drugs (OADs) (PDM group). All subjects then started or intensified OADs therapy and followed up for 91 days. Glycemic control was determined according to HbA1c at day 91 with HbA1c <7% considered good. RESULTS: The proportions of patients with good glycemic control after follow up for 91 days were 66.9% and 34.8% in NDM group and PDM group respectively. Logistic regression analysis showed that the change in GA at 28 days was the only predictor of good glycemic control in NDM patients (OR = 1.630, 95% CI 1.300-2.044, P < 0.001). In PDM patients, changes in GA at 28 days, CPI, baseline HbA1c, diabetic duration, and BMI were all independent predictors of good glycemic control (All P < 0.05). CONCLUSIONS: GA decline is a good predictor of future success in newly diagnosed patients. In patients intensifying therapy, beside GA decline, other individualized clinical characteristics should also be considered.

ABSTRACT

The improvement of glycemic control in patients with type 2 diabetes (T2D) is an urgent need in Asia. East Asian T2D patients have distinct characteristics, including relatively low body weight, early impairment of islet beta cell function with reduced insulin secretion and a marked increase in postprandial blood glucose levels. Control of postprandial hyperglycemia and beta cell preservation are key elements of the therapeutic strategy for these patients. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) reduce HbA1c, fasting plasma glucose, and (in particular) postprandial glucose levels, and slow gastric emptying, while minimizing the risk of hypoglycemia and weight gain. Compared with long-acting GLP-1RAs, short-acting GLP-1RAs produce greater slowing of gastric emptying (which is a key factor driving the reduction of postprandial glycemia) and induce beta cell rest rather than promoting postprandial insulin secretion when used under physiological conditions. GLP-1RAs have greater efficacy in Asian than Caucasian patients. GLP-1RA add-on therapy provides clinically meaningful reductions in HbA1c and postprandial glucose in Asians with T2D inadequately controlled by oral antidiabetic drugs (OADs) or basal insulin ± OADs. Premixed insulin is often prescribed for T2D patients in China. A short-acting GLP-1RA plus basal insulin is an alternative to premixed insulin, resulting in better efficacy and a lower risk of hypoglycemia and weight gain. In conclusion, GLP-1RAs, especially short-acting GLP-1RAs, are a practical treatment option for East Asian patients with T2D inadequately controlled by OADs or basal insulin.Funding: Sanofi.

ABSTRACT

Pituitary stalk interruption syndrome (PSIS) is associated with simultaneous or subsequent pituitary hormone deficiencies (PHDs). Although the clinical features of multiple PHDs are well known, the status of the thyrotrophic axis in PSIS has not been thoroughly investigated.The clinical data of 89 PSIS patients and 34 Sheehan syndrome (SS) patients were retrospectively analyzed.The prevalence of central hypothyroidism in the PSIS patients and the SS patients was 79.8% and 70.6%, respectively. The thyroid-stimulating hormone (TSH) levels in the PSIS patients were significantly higher in comparison with the SS patients (5.13 ±â€Š3.40 vs 1.67 ±â€Š1.20 mU/L, P < .05). TSH elevation (8.79 ±â€Š3.17 mU/L) was noticed in 29 of 71 (40.85%) hypothyroid PSIS patients but not in the 24 hypothyroid SS patients. The TSH levels in the hypothyroid PSIS patients were significantly higher in comparison with the euthyroid PSIS patients (5.42 ±â€Š3.67 vs 3.66 ±â€Š1.50 mU/L). Thyroid hormone replacement significantly reduced the TSH levels in the PSIS patients with elevated TSH levels from 7.24 ±â€Š0.98 to 1.67 ±â€Š1.51 mU/L (P < .05). The logistic regression analysis suggested that TSH level was not significantly associated with pituitary stalk status and height of the anterior pituitary gland.PSIS is a newly recognized cause of central hypothyroidism. The proportion and amplitude of TSH elevations are higher in PSIS than in other causes of central hypothyroidism.

ABSTRACT

Primary macronodular adrenal hyperplasia (PMAH), also known in the past as bilateral macronodular adrenalhyperplasia or adrenocorticotropin (ACTH)-independent macronodular adrenal hyperplasia, is a rare type of Cushing's syndrome (CS) and is associated with bilateralenlargement of the adrenal glands. It accounts for <1% of all endogenous cases of CS. In order toidentify the pathogenic mutations in the causative gene of (AIMAH pedigrees, Whole-genome sequencing of three patients in family I was used to retrieve candidate causative genes. Meanwhile, the causative gene was identified by Sanger sequencing from the two pedigrees. Sequencing of ARMC5 exons of three patients was carried out to identify somatic mutations. Moreover, haploid clone of one tumor DNA sample was conducted. ARMC5 was the causative gene of two pedigrees confirmed by whole-genome sequencing (WGA) and Sanger sequencing. The variant sites of the two families were c.C943T (p.R315W) and c.C1960T (p.R654X), respectively. Autosomal dominant inheritance of AIMAH was confirmed by genotypes of one family member. Several somatic mutations were discovered in tumor DNA samples. In addition, haploid clone of tumor DNA was confirmed by germline mutation and somaticmutation, which suggested the pathogenic mechanism of "two-hit-model." ARMC5 was the causative gene of AIMAH pedigrees. This AIMAH in this study presented autosomal dominant inheritance, fitting to Mendelian inheritance law. However, the pathogenic mode of this disease showed as compound heterozygote.

ABSTRACT

INTRODUCTION: Lixisenatide is a novel GLP-1 receptor agonist for the treatment of type 2 diabetes mellitus (T2DM). Its efficacy and safety have been assessed in a series of phase 3 studies included in the GetGoal program. In these studies, lixisenatide was found to be superior to placebo in glycemic control. The aim of this meta-analysis was to assess the safety and efficacy of lixisenatide as an adjunct therapy in Asian patients with T2DM in adequately controlled with oral antidiabetic drugs (OADs). METHODS: We performed a meta-analysis from five lixisenatide phase 3 studies. In each of these multiethnic studies, patients with T2DM inadequately controlled (glycated hemoglobin, HbA1c ≥7%) with established OADs were randomized to lixisenatide or placebo for 24 weeks, with a balanced distribution of Asian patients in these two arms (503 and 338 patients in the intent-to-treat population, respectively). RESULTS: Lixisenatide was superior to placebo in reducing HbA1c (weighted, total mean difference -0.57%; P = 0.002). More patients treated with lixisenatide versus placebo achieved HbA1c targets of ≤7% (49.1% vs. 28.4%, P = 0.003). Lixisenatide was superior to placebo in lowering 2-h postprandial glucose (PPG) (weighted, total mean difference -5.50 mmol/l, P = 0.0005). More patients treated with lixisenatide versus placebo achieved 2-h PPG targets of ≤7.8 mmol/l (39.2% vs. 2.2%, P < 0.0001). More patients treated with lixisenatide versus placebo achieved both an HbA1c target of ≤7% and a 2-h PPG target of ≤10 mmol/l (34.8% vs. 2.69%, P < 0.00001). The body weight of the lixisenatide group tended to decrease. Lixisenatide was generally well tolerated. CONCLUSION: Lixisenatide as an adjunct therapy can significantly improve the glycemic control of Asian patients with type 2 DM who do not meet targets for glycemic control with an established OAD regimen.

ABSTRACT

AIMS: This study was to determine whether serum glycated albumin (GA) was a better indicator of glycemic control than hemoglobin A1c (HbA1c) when starting a new treatment regimen for type 2 diabetes. METHODS: Newly diagnosed type 2 diabetes patients, or patients who had poor glycemic control with oral hypoglycemic agents, were enrolled at 10 hospitals in Beijing. Serum GA, HbA1c, fasting blood glucose (FBG), and C-peptide were assayed on Days 0, 14, 28, and 91 after treatment. RESULTS: Four hundred ninety-nine patients were enrolled. Mean FBG, GA and HbA1c decreased significantly in patients at Days 14, 28, and 91. In patients with improved glycemic control, the reduction of GA and HbA1c levels was 10.5±13.3% vs. 5.1±5.4% on Day 14, 16.0±13.4% vs. 9.0±7.0% on Day 28, and 18.0±16.7% vs. 18.3±9.4% on Day 91, respectively, compared with baseline values. Changes in GA on Day 14, 28 and 91 were all closely correlated with changes in HbA1c on Day 91. Change in GA on Day 14 was correlated with treatment effectiveness evaluated by HbA1c on Day 91. CONCLUSIONS: GA may be a useful marker for assessing glycemic control at an early stage of new diabetes treatment and assist in guiding adjustments to treatment and therapy.

ABSTRACT

BACKGROUND: Thyroid hormone resistance syndrome (THRS) is a rare disorder with increased concentrations of free thyroxine (FT4) and triiodothyronine (FT3), but normal or slightly increased thyroid-stimulating hormone (TSH). The mutations in the thyroid hormone receptor ß (THRß) gene are thought to be the main pathogenesis. OBJECTIVES: The aims of this study were to present 1 pedigree of Chinese THRS, summarize their clinical characteristics, and analyze the gene mutation. METHODS: The clinical characteristics and thyroid function of the proband and his family members were collected. Gene mutations were analyzed by DNA sequencing. RESULTS: The proband and his mother exhibited symptoms of hyperthyroidism, such as palpitations, heat intolerance, and perspiration. The mother also had atrial fibrillation. The rest of the kindred did not display clinical manifestations of hyper- or hypothyroidism. DNA sequencing revealed a heterozygous G>A missense mutation at position 949 in Exon 9 of THRß both in the patient and his mother, which led to the transition from alanine to threonine at position 317 of THRß protein (A317T), whereas the rest of the kindred did not share this mutation. The proband and his mother were diagnosed with pituitary resistance to thyroid hormone. Oral administration of methimazole was stopped and ß-receptor blockers were administrated. CONCLUSIONS: We present 1 pedigree of THRS with heterozygous A317T mutation in THRß gene in the proband and his mother, which is the first reported mutation in Chinese and provides a comprehensive review of available literature.

ABSTRACT

BACKGROUND: Type B insulin resistance is a rare autoimmune disease characterized by the presence of autoantibodies against the insulin receptor. Helicobacter pylori (H pylori) infection may play a causative role in the autoimmune diseases. CASE PRESENTATION: Here, we present a rare case of a 48-year old female patient, who had type B insulin resistance with systemic scleroderma and was successfully treated with multiple immune suppressants after eradication of Helicobacter pylori infection. CONCLUSION: The present case suggests H pylori infection-related pathological mechanism may contribute to type B insulin resistance syndrome and autoimmune disorders. Treatment toward H pylori may be helpful to relieve syndrome of type B insulin resistance for H pylori positive patients.

ABSTRACT

BACKGROUND: Reninoma is an extremely rare renal tumor characterized by excessive renin secretion causing secondary hypertension and hypokalemia. Reninoma is a benign and highly manageable lesion if it is discovered early and removed surgically. METHODS: We report six cases of reninoma and provide a literature review on this rare disease, highlighting the diagnostic evaluation and follow-up of each patient. RESULTS AND CONCLUSIONS: Reninoma should be considered in young adults with elevated renin activity and refractory hypertension. Imaging studies and selective venous catheterization are often helpful in identifying the lesion. In most cases of reninoma presenting with renin-mediated hypertension, conservative surgical treatment should be considered to remove the small, superficial lesion.

ABSTRACT

Aim. To investigate incidental adrenal enlargement clinical characteristics and functional status and analyze functional lesion risk factors. Materials and Methods. This retrospective study included 578 patients with adrenal imaging features showing enlargement. Incidental adrenal enlargement cases (78) were considered eligible. Demographics, functional diagnosis, adrenal imaging features, and concomitant diseases were analyzed. Results. The number of adrenal enlargements and proportion of incidental adrenal enlargement increased each year. Mean patient age was 50.32 years. Thirty-nine cases had unilateral enlargement on the left side and 3 on the right side; 36 had bilateral enlargement. Routine medical checkup was found to have the greatest chance (43.59%) of revealing clinical onsets leading to discovery. Biochemical and functional evaluation revealed 54 (69.23%) cases of nonfunctional lesions, 12 (15.38%) of subclinical Cushing syndrome, 6 (7.69%) of primary hyperaldosteronism, 1 (1.28%) of metastasis, and 5 (6.41%) of unknown functional status. Nodular adrenal enlargement (OR, 7.306; 95% CI, 1.727-28.667; P = 0.006) was a risk factor for functional lesions. Age and lesion location were not significant factors. Conclusion. Incidental adrenal enlargement is a frequent radiographic finding and is accompanied by diverse clinical factors that require proper evaluation and management. Nodular adrenal enlargement was a risk factor.

ABSTRACT

OBJECTIVE: To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome (MetS) and risk factors in adults in China. METHODS: A cross-sectional survey was condcuted in 14 provinces (autonomous region, municipality) in China. A total of 47,325 adults aged⋝20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation (IDF) criteria and modified IDF criteria. RESULTS: The age-standardized prevalence of MetS was 24.2% (22.1% in men and 25.8% in women) and 19.5% (22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1% (8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity (90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. CONCLUSION: Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.

ABSTRACT

BACKGROUND: The aim of the present study was to assess the efficacy of structured education in insulin-treated type 2 diabetes mellitus (T2DM) patients. METHODS: In a 16-week open-label randomized controlled study, 1511 T2DM patients with inadequate responses to two or more oral antidiabetic drugs (OADs) for >3 months (HbA1c >7.5%) were randomized (1:1) to either an education group (structured diabetes education plus insulin therapy) or a control group (usual care plus insulin therapy). Both groups discontinued previous OADs (except biguanides and α-glucosidase inhibitors) and started twice daily injections of 30% soluble-70% isophane recombinant insulin. The primary endpoint was the change in HbA1c from baseline. Efficacy and safety data were analyzed for within- and between-group differences. RESULTS: Of the initial 1511 patients, 1289 completed the study (643 in the control group; 646 in the education group). At the end of the study, significant reductions in HbA1c versus baseline were evident in both groups, but the reduction was greater in the education group (2.16% vs. 2.08%; P < 0.05). A higher proportion of patients in the education group achieved target HbA1c levels <7% (43.81% vs. 36.86%; P < 0.05) and ≤6.5% (28.48% vs. 22.71%; P < 0.05). In addition, patients in the education group showed greater increments in scores and improvement in the Morisky Medication Adherence Scale (P < 0.05). The overall incidence of hypoglycemic events was similar in the two groups. CONCLUSIONS: Structured education can promote the ability of patients to self-manage and their compliance with medications, thereby achieving better outcomes.

ABSTRACT

In addition to their hypotensive properties, angiotensin receptor blockers (ARBs) have been shown to exert clinical antidyslipidemic effects. The mechanism underlying these ARB lipid metabolic effects remains unclear. Some ARBs, for example, telmisartan, activate peroxisome proliferator-activated activated receptor-gamma (PPAR-gamma). We hypothesized that PPAR-gamma-activating ARBs might exert antidyslipidemic effects via PPAR-alpha. In this study, we assessed the effect of telmisartan on the expression of PPAR-alpha and lipoprotein lipase (LPL). PPAR-alpha expression was detected by reverse-transcription polymerase chain reaction and Western blot in HepG2 hepatocytes as well as differentiated C2C12 myocytes treated with increasing concentrations of telmisartan (0.1-10 µmol/L) for 48 h. Results showed that 1 µmol/L and 10 µmol/L telmisartan significantly increased the expression of PPAR-alpha mRNA and protein in HepG2 cells (p < 0.01). No effect was shown in differentiated C2C12 cells. Similarly, 1 µmol/L and 10 µmol/L telmisartan significantly increased the expression of LPL mRNA and protein in HepG2 cells (p < 0.01), and this increase was significantly (p < 0.01) inhibited by the PPAR-alpha-specific antagonist MK886. These results indicate that certain of the antidyslipidemic effects of telmisartan might be mediated via increased PPAR-alpha-dependent induction of LPL expression.

ABSTRACT

Endoplasmic reticulum (ER) stress and autophagy have both been reported to be associated with lipotoxicity in ß-cells, yet the relationship between them has not been fully clarified. In the present study, we tested the hypothesis that the ER stress-autophagic pathway in ß-cells is a downstream pathway activated following saturated fatty acid treatment. Mouse insulinoma (MIN6) ß-cells were treated with either palmitate or thapsigargin (TG) with or without various inhibitors. The results indicated that palmitate strongly enhanced the protein expression of microtubule-associated protein 1 light chain 3 (LC3)-II. Furthermore, the expression levels of ER stress markers, BiP and CHOP, and phosphorylation levels of JNK were increased after palmitate treatment. In addition, palmitate-induced autophagy was blocked by 500 µM of the ER stress inhibitor tauroursodeoxycholic acid (TUDCA) or 20 µM JNK inhibitor SP600125. In turn, the phosphorylation of Akt (Ser473) was also downregulated by palmitate, while the levels of insulin receptor ß (IRß) were not reduced. A further increase in LC3-II levels was observed in cells treated with both palmitate and 50 µM PI3K/Akt inhibitor LY294002 compared with cells treated with palmitate alone. Palmitate-induced phospho-Akt (Ser473) downregulation was also inhibited by TUDCA or SP600125. Pretreatment with the autophagy inhibitor 3-methyladenine (3-MA, 5 mM) for 1 h increased the expression of ER stress markers, and enhanced cell injuries caused by 0.1 µM TG, including decreased cell viability and insulin secretion. Palmitate induces autophagy in pancreatic ß-cells possibly through activation of ER stress and its downstream JNK pathway. Palmitate-induced autophagy may protect ß-cells against cell injuries caused by ER stress.

ABSTRACT

BACKGROUND: It has been suggested that glycated hemoglobin (HbA1c) underestimate the actual glycemic control levels in maintenance hemodialysis (MHD) patients, because of anemia and the using of erythropoietin (EPO); it was recommended that glycated albumin (GA) should be an alternative marker. Therefore, the assessment performances of glycemic control were compared between GA and HbA1c in this research by referring to mean plasma glucose (MPG) in diabetes mellitus (DM) patients undergoing MHD or not. METHODS: MPG was calculated according to the data registered at enrollment and follow-up 2 months later and corresponding HbA1c, albumin (ALB), GA, etc. were measured in 280 cases. A case-control study for comparing GA and HbA1c was done among the groups of MHD patients with DM (n=88) and without DM (NDM; n=90), and non-MHD ones with DM (n=102) using MPG for an actual glycemic control standard. RESULTS: In these 3 groups, only for DM patients' (whether undergoing MHD or not), GA and HbA1c correlated with MPG significantly (P < 0.01). Through linear regression analysis, it could be found that the regression curves of GA almost coincided in MHD and non-MHD patients with DM, because the intercepts (2.418 vs. 2.329) and slopes (0.053 vs. 0.057) were very close to each other. On the contrary, regression curves of HbA1c did not coincide in the two groups, because variance of the slopes (0.036 vs. 0.052) were relatively large. Through comparing receiver operating characteristic (ROC) areas under the curve (AUC), it could be understood that the assessment performances of GA and HbA1c in MHD patients were lower than those in non-MHD ones, and assessment performance of HbA1c in MHD patients was better than GA (P < 0.05). In addition, the effects of Hb and EPO dose on HbA1c, or that of ALB on GA were unobvious in our study. CONCLUSIONS: Actual glycemic control level in MHD patients with DM may be underestimated by HbA1c, and it could be avoided by GA; however, glycemic evaluating performance of HbA1c may be still better than that of GA. Therefore, HbA1c should not be replaced completely although GA can be used as a choice to monitor glycemic level.

ABSTRACT

BACKGROUND AND AIM: Limitations of the currently recommended stepwise treatment pathway for type 2 diabetes mellitus (T2DM), especially the failure of monotherapies to maintain good glycemic control, have prompted use of early, more aggressive combination therapies.The VISION study is designed to explore the efficacy and safety of vildagliptin as an add-on to metformin therapy compared with up-titration of metformin monotherapy in Chinese patients with T2DM. METHODS: VISION, a 24-week, phase 4, prospective, randomized, multicenter, open-label, parallel-group study, will include 3312 Chinese T2DM patients aged ≥18 years who are inadequately controlled (6.5% >HbA1c ≤9%) by metformin (750-1000 mg/day). Eligible patients will be randomized to receive either vildagliptin plus metformin or up-titration of metformin monotherapy (5:1). Patients will also be subgrouped (1:1:1:1) based on their age and body mass index (BMI): <60 years and <24 kg/m²; <60 years and ≥24 kg/m²; ≥60 years and <24 kg/m²; and ≥60 years and ≥24 kg/m². CONCLUSION: The VISION study will test the hypothesis that early use of combination therapy with vildagliptin and metformin will provide good glycemic control and will be better tolerated than up-titration of metformin monotherapy. The study will also correlate these benefits with age and BMI.

ABSTRACT

OBJECTIVE: To investigate the effects of vitamin-mineral supplement on young males with physical overtraining. METHODS: Two hundred and forty male Chinese field artillery personnel who undertook large scale and endurance military training and were on ordinary Chinese diet were randomized to receive a multivitamin/multimineral supplement or a placebo for 1 week. After a 1-week wash-out period, a cross-over with 1 week course of a placebo or multivitamin/multimineral supplement was conducted. Blood and urine samples were analyzed for adrenal, gonadal and thyroid hormones. In addition, cellular immune parameters (CD3+, CD3+CD4+, CD3+CD8+, CD4/CD8, CD3-CD56+, CD3-CD19+) were examined and psychological tests were performed before and after the training program and nutrition intervention. RESULTS: After a large scale and endurance military training, the participants showed significantly increased thyroid function, decreased adrenal cortex, testosterone and immunological function, and significantly increased somatization, anger and tension. Compared to placebo, multivitamin/ multimineral intervention showed significant effects on functional recovery of the pituitary - adrenal axis, pituitary-gonadal axis, pituitary- thyroid axis and immune system as well as psychological parameters. CONCLUSION: High-intensity military operations have significant impacts on the psychology, physical ability and neuroendocrine-immune system in young males. Appropriate supplementation of multivitamin/multimineral can facilitate the recovery of the psychology, physical ability and neuroendocrine-immune system in young males who take ordinary Chinese diet.

ABSTRACT

BACKGROUND: The prevalence of type 2 diabetes mellitus (T2DM) is increasing rapidly among Chinese adults, and limited data are available on T2DM management and the status of glycemic control in China. We assessed the efficacy of oral antidiabetes drugs (OADs), glucagon-like peptide-1 (GLP-1) receptor agonists, and insulin for treatment of T2DM across multiple regions in China. METHODS: This was a multicenter, cross-sectional survey of outpatients conducted in 606 hospitals across China. Data from all the patients were collected between April and June, 2011. RESULTS: A total of 238,639 patients were included in the survey. Eligible patients were treated with either OADs alone (n=157,212 [65.88%]), OADs plus insulin (n=80,973 [33.93%]), or OADs plus GLP-1 receptor agonists (n=454 [0.19%]). The OAD monotherapy, OAD + insulin, and OAD + GLP-1 receptor agonist groups had mean glycosylated hemoglobin (HbA1c) levels (±SD) of 7.67% (±1.58%), 8.21% (±1.91%), and 7.80% (±1.76%), respectively. Among those three groups, 34.63%, 26.21%, and 36.12% met the goal of HbA1c <7.0%, respectively. Mean HbA1c and achievement of A1c <7.0% was related to the duration of T2DM. CONCLUSIONS: Less than one third of the patients had achieved the goal of HbA1c <7.0%. Glycemic control decreased and insulin use increased with the duration of diabetes.

ABSTRACT

OBJECTIVE: Study of Once-daily LeVEmir(®) (SOLVE(TM)) was a 24-week international observational study to evaluate the safety and effectiveness of initiating once-daily insulin detemir (Levemir) as add-on therapy in patients with type 2 diabetes mellitus (T2DM) who failed treatment of oral anti-diabetic drugs (OAD). METHODS: The present study was derived from the data of Chinese cohort. A total of 3272 patients with T2DM failing OAD were enrolled in the study. Determir were prescribed to the patients by the decision of the physician. Clinical data were collected at baseline, week 12 and week 24 to evaluate the safety and effectiveness of detemir. RESULTS: The age of the patients was (56.2 ± 10.8) years with a diabetes duration of (7.1 ± 5.2) years. Their BMI was (25.3 ± 3.3) kg/m(2). No patient experienced any major or nocturnal hypoglycaemic event during the study. After 24 weeks of treatment, the glycosylated hemoglobin A1c (HbA1c) decreased from (8.33 ± 1.69)% to (7.16 ± 1.18)% with a mean change of -1.17%, the fasting plasma glucose decreased from (9.52 ± 2.59) mmol/L to (6.84 ± 1.42) mmol/L with a mean change of -2.7 mmol/L, and the 7-point blood glucose profile improved overall. Totally 49.1% of patients achieved HbA1c < 7%. The mean body weight decreased by 0.15 kg. CONCLUSIONS: Insulin detemir administered once daily as add-on therapy in patients with T2DM failing OAD regimen significantly reduces the risk of major hypoglycemia, improves glycemic control, increases the percentage of patients achieving treatment target with neutral effect on body weight.
