Diabetes is one of the most serious chronic diseases. Numerous drugs including oral agents and traditional Chinese medicines, such as sitagliptin phosphate (SP) and Fuzhujiangtang granules (FJG), have been discovered to treat diabetes and used in combination in clinical practice. However, the exact effect and underlying mechanism of using combined medicine is not clear. In this study, we compared the antidiabetic effect of SP, FJG, and SP plus FJG (SP-FJG) using forty 8-week-old Zucker diabetic fatty (ZDF) rats and 10 age-matched Zucker lean rats as the normal control group. ZDF rats were treated with different therapies, respectively, for 6 weeks. The study showed that the fast blood glucose, random blood glucose (RBG), oral glucose tolerance test (OGTT), insulin tolerance test (ITT), homeostasis model of assessment-insulin resistance index, triglyceride (TC), superoxide dismutase, and malondialdehyde of each treatment group were improved when compared with the diabetes mellitus (DM) control group. Using SP-FJG in combination had better improvements in OGTT, fast serum insulin levels, TNF-α, and IL-6 compared with using SP individually. Besides, the increased LDL and TC caused by using SP was attenuated by using FJG in combination. Meanwhile, compared with the DM group, 1781 differentially expressed genes (DEGs) (including 1248 mRNA, 211 ncRNA, 202 cirRNA, and 120 miRNA) were enriched in 58 pathways. Through analysis of ceRNA networks, we found that rno-miR-326-3p, rno-miR-423-5p, rno-miR-15b-5p, rno-let-7c-5p, and rno-let-7b-5p were related to pharmacodynamics in different groups. By analyzing the protein-protein interaction (PPI) and coexpression networks of the transcriptomes of different groups, it is inferred that Lrrk2 and Irak3 may be pharmacodynamic genes for type 2 diabetes mellitus (T2DM). Our research compared the treatment of SP, FJG, and SP-FJG and acquainted the PPI network, coexpression network, mutations, and pharmacodynamics genes, which reveals the new mechanisms of pathogenesis of T2DM.

Introduction: Gestational diabetes mellitus is common disorder in pregnancy. It is associated with adverse pregnancy outcome. There is no consensus regarding the optimal approach to screening of gestational diabetes mellitus. The present study has tried toobserve the value of fasting blood glucose in screening of gestational diabetes. Objective: To determine the frequency of patients in whomfasting blood glucose and 100gm glucose tolerance show agreement for screening of gestational diabetes mellitus at 24 -28 wks. Studydesign: Comparative cross sectional study. Settings: The study was conducted at Gynecology and Obstetrics department Shaikh ZayedFederal Post Graduate Institute Lahore. Duration of study with dates: 6 months from 12Nov 2010 to 11 May 2011. Material and method: Thestudy included 135 booked patients with positive family history of diabetes mellitus. All patients underwent fasting blood glucose at 24-28 weeksof gestation, regardless of results of fasting blood glucose on next visit they underwent 100g oral glucose tolerance test (OGTT). The agreementbetween fasting blood glucose and 100g oral glucose tolerance test was calculated in frequency and percentages. Results: The mean age ofwomen in studied population was 27.15±3.70.Out of 135 patients 86.7 %( 117) showed agreement between results of fasting blood glucose and100g OGTT while 13.31 %( 18) showed no agreement between both of the tests. Conclusions: Fasting blood glucose is a good screeningoption for gestational diabetes mellitus along with positive history. It provides a simple, cheap and more practical test for screening of gestationaldiabetes mellitus. However diagnostic confirmation with 100g OGTT should be done.

Abstract Background Blood glucose levels during pregnancy may reflect the severity of insulin secretory defects and/or insulin resistance during gestational diabetes mellitus (GDM) pregnancy. We hypothesized that suboptimal glycemic control in women with GDM could increase the risk of postpartum type 2 diabetes mellitus (T2DM) or prediabetes. Our objective was to evaluate the impact of plasma glucose levels throughout GDM pregnancy on the risk of postpartum T2DM or prediabetes. Methods The medical records of 706 women with GDM who underwent a postpartum 75-g, 2-hour oral glucose tolerance test at our institution between January 2011 and December 2018 were reviewed. These women were classified into 2 groups according to glycemic control during pregnancy: ≤ 1 occasion of either fasting glucose ≥ 95 mg/dL or 2-hour postprandial glucose ≥ 120 mg/dL was defined as optimal glycemic control or else was classified as suboptimal glycemic control. Rates of postpartum T2DM and prediabetes were compared between women with optimal (n = 505) and suboptimal (n = 201) glycemic control. Results The rates of postpartum T2DM and prediabetes were significantly higher in the suboptimal glycemic control group than in the optimal glycemic control group: 22.4% vs. 3.0%, P < 0.001 for T2DM and 45.3% vs. 23.5%, P < 0.001 for prediabetes. In a multivariate analysis, suboptimal glucose control during pregnancy was an independent risk factor for developing either postpartum T2DM or prediabetes. The adjusted odds ratios were 8.4 (95% confidence interval, 3.5–20.3) for T2DM and 3.9 (95% confidence interval, 2.5–6.1) for prediabetes. Conclusion Our findings suggest that blood glucose levels during GDM pregnancy have an impact on the risk of postpartum T2DM and prediabetes.

Ergosterol (ERG) has been widely used in the development of novel drugs due to its unique physiological function. However, little is known about the protective effects of ERG on diabetes. Hence, the current study was designed to evaluate the positive role of ergosterol on streptozotocin- (STZ-) induced diabetes in mice. Oral glucose tolerance test (OGTT) was carried out to assess blood glucose level. Biochemical parameters such as uric acid, creatinine, serum insulin, triglycerides (TG), and total cholesterol (TC) were also measured. Pathological condition of kidney was examined by hematoxylin-eosin (H&E) staining. The expressions of PI3K, p-PI3K, Akt, p-Akt, NF-κBp65, p-NF-κBp65, IκBα, and p-IκBαwere analyzed by western blot. ERG significantly reduced the concentrations of blood glucose, uric acid, creatinine, TG, and TC. Serum insulin was elevated with ERG treatment. In addition, renal pathologic changes of diabetes mice were also alleviated by ERG. Obtained data revealed that ERG restored the levels of PI3K/Akt/NF-κB signaling-related proteins in comparison with diabetes mice. Above all, it could be assumed that ERG might play a positive role in regulating STZ-induced diabetes through suppressing PI3K/Akt/NF-κB pathway.

Glucagon Like Peptide 1

Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are released during meals from endocrine cells located in the gut mucosa and stimulate insulin secretion from pancreatic β-cells in a glucose-dependent manner. Although the gut epithelium senses luminal sugars, the mechanism of sugar sensing and its downstream events coupled to the release of the incretin hormones are not clearly elucidated. Recently, it was reported that sucralose, a sweetener that activates the sweet receptors of taste buds, triggers incretin release from a murine enteroendocrine cell line in vitro. We confirmed that immunoreactivity of α-gustducin, a key G-coupled protein involved in taste sensing, is sometimes colocalized with GIP in rat duodenum. We investigated whether secretion of incretins in response to carbohydrates is mediated via taste receptors by feeding rats the sweet-tasting compounds saccharin, acesulfame potassium, d-tryptophan, sucralose, or stevia. Oral gavage of these sweeteners did not reduce the blood glucose excursion to a subsequent intraperitoneal glucose tolerance test. Neither oral sucralose nor oral stevia reduced blood glucose levels in Zucker diabetic fatty rats. Finally, whereas oral glucose increased plasma GIP levels ∼4-fold and GLP-1 levels ∼2.5-fold postadministration, none of the sweeteners tested significantly increased levels of these incretins. Collectively, our findings do not support the concept that release of incretins from enteroendocrine cells is triggered by carbohydrates via a pathway identical to the sensation of “sweet taste” in the tongue.

Research background. The use of plants and their extracts in treatments of chronic diseases is widely known in traditional medicine. The aim of this study is to determine the effects of 10-day consumption of Prunus spinosa L. flower extract on blood glucose, glycaemic load, serum α-amlyase and serum insulin, in normoglycaemic and hypergycaemic (alloxan) mice model. Experimental approach. Normoglycemic and hyperglycemic (alloxan treated, 150 mg/kg body mass) C57BL/6 mice were treated daily, during 10 days, with Prunus spinosa L. flower extract by gavage. The sugar content within extract was determined by HPLC analysis. In mice, blood and serum blood glucose level and OGTT-test were determined by blood glucometer. Serum insulin was determined by ELISA assay and α-amlyase by colourimetric assay. Results and conclusions. The Prunus spinosa L. flower extract increased glucose in normoglycaemic mice by 30 % after 1st and 5th day and by 17 % after 10th day of consumption in normoglycaemic mice. It is a consequence of released sugars because sugar analysis revealed 59.8 mg/L monosaccharides, mainly fructose (55.7 mg/L) and glucose (24.3 mg/L) within the extract. On the opposite, the extract consumption, reduced serum blood glucose in alloxan-induced hyperglycaemic mice by 29 % after 10 days of treatment. Oral glucose tolerance test also confirmed that that in the hyperglycaemic group treated with Prunus spinosa L. flower extract glucose homeostasis was improved and showed decrease in blood glucose, since the blood glucose over the period of 120 min, glucose homeostasis is faster achieved after treatment with shows that in Prunus spinosa L. flower extract. Serum insulin increased by 49 % and serum alpha amylase by 46 % after 10 days of treatment with Prunus spinosa L. flower extract in hyperglycaemic group. Thus, it can be concluded that Prunus spinosa L. flower extract improved glucose tolerance, enhanced insulin secretion and lowered serum α-amylase activity. Novelty and scientific contribution. The results examined for the first time the potential of Prunus spinosa L. flower extract in hyperglycaemia management.

This study is aimed at determination whether pregnant women who develop hyperemesis gravidarum in the first trimester have a tendency to develop gestational diabetes mellitus (GDM). It is also aimed at identification of effects of hyperemesis gravidarum and GDM on prenatal and neonatal status in case they were detected together. Hyperemesis gravidarum diagnose was based on the following signs and symptoms. To diagnose GDM, first trimester fasting blood glucose measurement and subsequent blood glucose monitoring and 75-g oral glucose tolerance test (OGTT) were performed in the second trimester. A total of 949 singleton pregnant women (95 with and 852 without hyperemesis gravidarum) who met our criteria were included in the study. In the first trimester, plasma blood glucose and positive GDM screening were found to be significantly higher in the hyperemesis gravidarum group compared to the control group (p=0.042 and p<0.001, respectively). However, actual GDM cases were similar between both groups. The positive predictive value was significantly lower in the hyperemesis gravidarum group (28.5% vs. 72.7%, p=0.003). In the second trimester, the prevalence of GDM was 6.6% in the hyperemesis gravidarum group and 7.3% in the control group, with no significant difference (p=0.218) between-groups. In this study, hyperemesis gravidarum was found to cause changes in maternal metabolism in the first trimester of pregnancy due to limited calorie intake and fasting; in the presence of hyperemesis gravidarum, it should be known that the positive predictive value of first trimester gestational diabetes screening may decrease and the diagnosis of pseudo-GDM may increase.

Streptozotocin Induced Diabetes

Streptozotocin (STZ) was used to induce the diabetic rat model. STZ rats were treated with mildronate (100 mg/kg daily, per os or intraperitoneally for 6 weeks). Body weight, blood glucose, triglyceride, ketone body concentrations, glycated hemoglobin percent (HbA1c%), glucose tolerance, and the development of neuropathic pain were monitored throughout the experiment. In the STZ + mildronate group, mildronate treatment caused a significant decrease in mean blood glucose (on week 4) and triglyceride concentrations (on weeks 3-6), significantly slowed the increase in HbA1c% (on week 6) and improved glucose tolerance 120 minutes after glucose ingestion during oral glucose tolerance test versus the STZ group. Mildronate completely protected development of STZ-induced neuropathic pain from the first administration week up to end of the experiment. The obtained data indicate clinical usefulness of the drug for the treatment of diabetes mellitus and its complications.

Background. Gestational diabetes mellitus (GDM) is a common complication of pregnancy. It can cause significant problems for the mother and offspring, such as caesarean delivery, birth trauma and the development of type 2 diabetes mellitus (T2DM) in the future. The identification and correction of modifiable risk factors for GDM will provide a possibility to prevent these complications. Aim. This study aimed to identify the most significant lifestyle parameters affecting the risk of developing GDM. Methods. The study included 680 pregnant women who underwent oral glucose tolerance test at 2432 weeks of pregnancy and responded to a questionnaire comprising the following sections stratified in a semi-quantitative manner: the consumption of major food groups and drinks and the amount of physical activity and smoking before and during pregnancy. A logistic regression analysis was performed to identify lifestyle parameters that influence GDM development. GDM was diagnosed according to the IADPSG criteria. Results. GDM was diagnosed in 266 women; the other 414 women formed the control group. The most significant dietary risk factor for developing GDM was the consumption of sausage(s), dried fruits and fresh fruits. Eating sausage(s) more than thrice a week during pregnancy increased the risk of developing GDM by 2.4 times [95% confidence interval (CI), 1.53.8; p 0.001] and so did the consumption of dried fruits more than thrice a week during pregnancy [odds ratio (OR), 6.5; 95% CI, 2.516.8; p 0.001)] compared with the risk of GDM by less consumption of these food groups. A regular consumption of fresh fruits more than 12 times a week during pregnancy reduced the risk of GDM (OR, 0.5; 95% CI, 0.30.8; p = 0.015). The habit of climbing at least four floors per day during pregnancy also reduced the risk of GDM (OR, 0.7; 95% CI, 0.51.0; p = 0.069). Conclusions. The recommendations for GDM prevention should include limiting the consumption of sausage(s) and dried fruits, increasing the consumption of fresh fruits and introducing regular physical activities, such as climbing stairs.

Glucose Metabolism Disorder

Abstract [Objective]: Hepcidin and ferroportin are major regulators of iron metabolism. Although many previous studies have shown that iron metabolism disorder may contribute to the pathogenesis of Type 2 diabetes mellitus (DM), few studies have investigated hepcidin and other iron metabolism parameters in women with gestational diabetes mellitus (GDM). The purpose of this study was to determine the relationship between hepcidin, ferroportin and GDM. [Methods]: A case-control study was conducted in 85 women with GDM and 85 women without GDM (controls) who received regular prenatal care at the Obstetrics and Gynecology Hospital of Fudan University from October 2015 to May 2016. Serum ferritin (SF), hepcidin (Hepc), ferroportin (FPN), and soluble transferrin receptor (sTfR), as well as other clinical parameters, were detected and analyzed in all groups. [Results]: The levels of fasting plasma glucose (FPG), oral glucose tolerance test (OGTT) 1-h and 2-h plasma glucose, glycated hemoglobin (HbA1c), SF, Hepc, FPN and sTfR as well as homeostasis model assessment for insulin resistance (HOMA-IR) were significantly higher in the GDM group (P<0.05 for all). In the GDM group, FPN was positively correlated OGTT-1 h and OGTT-2 h In the control group, only sTfR was positively correlated with OGTT-1 h. There was no correlation between the iron metabolism indicators in both GDM and control group.[Conclusion]: Hepc, FPN sRfR and SF levels were higher in the GDM group. Elevated Hepc and FPN are associated with glucose metabolism disorder and may play an important role in GDM.

Gongronema Latifolium

Gongronema latifolium (GL) has been used traditionally in the management of various ailments. The effects of GL on some haematological and biochemical parameters in fructose-induced hyperglycaemia were studied. Forty rats were randomly assigned to four groups of 10 rats each. Control was received normal rat chow, fructose + G. latifolium group was received 66% D-fructose mixed with 34% chow and crude leaf extract of GL daily. Fructose only group was received 66% D-fructose and the fourth group was received GL extract only respectively for 30 days. All animals were fed ad libitum and had free access to water. Oral blood glucose tolerance test was determined using 2 g/Kg in all groups of rats and blood samples were obtained by cardiac puncture for haematological and biochemical analyses. The blood glucose level was significantly raised in fructose-fed only group (140.6 ± 2.9 mg/dl) when compared to GL + fructose group (110.3 ±5.8 mg/dl) and control (88.1 ± 3.6 mg/dl). There was observed significant reductions in blood glucose and glucose tolerance following GL supplementation. The lipid profile values were significantly higher in fructose-fed group compared with other groups but these levels were significantly reduced following GL supplementation. The white blood cells (WBC) and platelets count in GL and fructose + GL group were significantly raised when compared with the control group. The red cell parameters were not significantly altered compared to the control group. The results show that the consumption of G. latifolium reduces hyperglycaemia and hyperlipidaemia hence the cardiovascular risk factors observed in diabetes mellitus.
