Purpose: This study aimed to analyze the content and effectiveness of psychosocial support interventions for women with gestational diabetes mellitus (GDM). Methods: The following databases were searched with no limitation of the time period: Ovid-MEDLINE, Cochrane Library, Ovid-Embase, CINAHL, PsycINFO, NDSL, KoreaMed, RISS, and KISS. Two investigators independently reviewed and selected articles according to the predefined inclusion/exclusion criteria. ROB 2.0 and the RoBANS 2.0 checklist were used to evaluate study quality. Results: Based on the 14 selected studies, psychosocial support interventions were provided for the purpose of (1) informational support (including GDM and diabetes mellitus information; how to manage diet, exercise, stress, blood glucose, and weight; postpartum management; and prevention of type 2 diabetes mellitus); (2) self-management motivation (setting goals for diet and exercise management, glucose monitoring, and enhancing positive health behaviors); (3) relaxation (practicing breathing and/or meditation); and (4) emotional support (sharing opinions and support). Psychosocial supportive interventions to women with GDM lead to behavioral change, mostly in the form of self-care behavior; they also reduce depression, anxiety and stress, and have an impact on improving self-efficacy. These interventions contribute to lowering physiological parameters such as fasting plasma glucose, glycated hemoglobin, and 2-hour postprandial glucose levels. Conclusion: Psychosocial supportive interventions can indeed positively affect self-care behaviors, lifestyle changes, and physiological parameters in women with GDM. Nurses can play a pivotal role in integrative management and can streamline the care for women with GDM during pregnancy and following birth, especially through psychosocial support interventions.

To develop basidiomycetes-fermented cereals with hypoglycemic property, inhibitory effects of basidiomycetes mycelia and basidiomycetes-fermented cereals on postprandial glucose were investigated. In vitro effect of basidiomycetes mycelia on retarding the membrane transport of glucose was compared with pectin. For basidiomycetes mycelia, $13.1{\pm}3.6{\sim}41.8{\pm}8.0%$ of total glucose remained in inner solution of dialysis membrane after dialysis for 120 min, indicating that most of basidiomycetes mycelia might effectively retard membrane transport of glucose. Glucose tolerance of basidiomycetes mycelia and basidiomycetes-fermented cereals was tested on streptozotocin-induced diabetic rats administrated with maltose. Postprandial glucose levels of basidiomycetes mycelia, $389.4{\pm}43.8{\sim}426.3{\pm}49.4mg/dL$, were considerably lower than that of control, $535.3{\pm}78.6mg/dL$, at 30 minutes after maltose administration. Namely, basidiomycetes mycelia showed better postprandial glucose lowering effect than pectin. Brown rice and barley fermented with Paecilomyces japonica showed much lower postprandial glucose level than raw brown rice and barley, especially hypoglycemic effect of barley fermented with Paecilomyces japonica was significant.

The goal of this study was to develop an optimal formula for cookies containing soybean/seoritae, Hwanggum, and isomalto-oligosaccharide using response surface methodology to achieve a blood glucose lowering effect. The model showed a good fit with the experimental data [$R^2=0.92$ (soybean) and 0.93 (seoritae)]. However, the p-value of lack of fit was less than 0.05 and ridge analysis was used to determine an optimal formula. The estimated optimal conditions were as follows: soybean cookie: 68.7% soybean, 2.5% Hwanggum, and 75.2% isomalto-oligosaccharide; seoritae cookie: 56.5% soybean, 3.8% Hwanggum, and 56.2% isomalto-oligosaccharide. The area under the curve and glycemic index were significantly lower in the soybean cookie group than in the control. The glycemic load (GL) index of the soybean (19.9) cookie was in the range of a low-glycemic food (<20 GL). These results can be applied to develop a cookie with a blood glucose lowering effect.

Weanling male rats of Wistar strain were fed relatively high-calories-diet containing 1% (K$_1$ group), 5% (K$_{5}$ group) and 10% Chinese cabbage kimchi juice (K$_{10}$ group) for 4 weeks to study their effects on body weight gain rate, serum lipids levels and other blood biochemical parameters. In this study it was found out that significant decrease in body weight gain rate, diet efficiency ratio, serum triglyceride level, serum total cholesterol level, blood glucose level and LDL-cholesterol level was observed in $K_{10}$ group as compared to control group fed only high-calories-diet. Significant increase in HDL-cholesterol level, GPT activity, GOT activity and creatinine level was found in $K_{10}$ group as compared to control group. But creatinine level, GPT and GOT activity of $K_{10}$ group were within the normal ranges. The results suggest that long term intake of traditional Chinese cabbage kimchi in large dose have the lowering effect on blood lipid and blood glucose level. There is no possibility of adverse actions on renal and hepatic functions by ordinary intake of Chinese cabbage kimchi in spite of being rich in salt and hot spices such as garlic, onion, ginger and red pepper.r.r.

Many benefits of silk protein fibroin (SPF) have been suggested in biomedical applications; and notably, significant SPF effects have been observed for metabolic syndromes that are directly linked to insulin resistance, such as type 2 diabetes mellitus (T2DM). Based on our previous findings, we believe that SPF from spiders exhibits outstanding glucose-lowering effects in diabetic BKS.Cg-m+/+Lepr^db mice. In order to evaluate the dietary effects of SPF in diabetic animals, we generated several lines of transgenic rice (TR) that expresses SPF, and the feeding of TR-SPF to diabetic animals decreased blood glucose levels, but did not change insulin levels. Western blot analyses of hepatic proteins showed that AMP-activated protein kinase (AMPK) expression and phosphorylation both decreased in TR-SPF-fed groups, compared with controls. This finding suggests that the glucose-lowering effects in this diabetic animal model might be AMPK-independent. In contrast, six-transmembrane protein of prostate 2 (STAMP2) was upregulated after TR-SPF exposure. Together with STAMP2, the Akt protein phosphorylation increased after TR-SPF exposure, which indicates that STAMP2 leads to Akt phosphorylation and thus increases insulin sensitivity in hepatocytes. Importantly, the hepatic steatosis that was seen in the liver of diabetic mice was remarkably alleviated in TR-SPF-fed mice. Hepatocytes that were immunopositive for STAMP2 were overwhelmingly observed in hepatic tissues from TR-SPF-fed mice compared to the control. Taken together, these results suggest that feeding diabetic mice with TR-SPF upregulates STAMP2 expression and increases Akt phosphorylation in hepatic tissues and thus potentially alleviates insulin resistance and hepatic steatosis.

The use of herbals has increased considerably while their efficacy and safety remain untested. This unsupported surge in demand has prompted a call for their clinical evaluation. One area in which evaluations are emerging is ginseng and diabetes. Growing evidence is accumulating from in vitro and animal models indicating that various ginseng species, American (Panax quinquefolius L), Asian (Panax ginseng C.A. Meyer), Korean Red, San-chi (Panax notoginseng [Burk.] P.R. Chen), and the non-panax species Siberian (Eleutherococcus senticossus) ginsing, and their fractions, saponins (ginsenosides) and peptidoglycans (panaxans for panax species and eleutehrans for Siberian ginseng), might affect carbohydrate metabolism and related signaling molecules. Recent human studies from our laboratory have also shown a blood glucose lowering effect of American ginseng (AG) and some other ginseng spices postprandially after acute administration and chronically after administration for 8-weeks in people with type 2 diabetes. Although generally encouraging, these data only indicate a need for more evaluations of ginsengs safety and efficacy. Because of poor industry standardization, it is not known whether all ginsengs will affect blood glucose. In this regards some ginseng batches have demonstrated null effects while others have even raised postprandial glycemia. Clinical research should therefore focus on components involved in its glucose lowering effects.

the ginseng polypeptide (GPP) isolated from the root of Panax ginseng C.A. Meyer was demonstrated to decrease the levels of blood sugar and hepatic glycogen when injected intravenously to rats at a doses of 50-200mg/kg without affecting blood total lipid. When mice were injected subcutaneously daily at a dose of 50 and 100mg/kg for 7 successive days, GPP was also found to decreased blood sugar and hepatic glycoge. In addition, GPP was found to decrease various experimenta hyperglycemias induced by injection of adrenaline, glucose and alloxan. GPP exhibited inhibiting effect on the glycogen enhancement induced by glucose, but strengthening effect on the glycogen decrease induced by adrenaline. When the levels of blood total lipid and liver glycogen were increased by alloxan, GPP was shown to inhibit these changes except its lowering blood sugar. the toxicity of GPP is very low, its LD50 was found to be 1.62$\pm$0.130 g/kg for iv.

In the past decade, the incidence of type 2 diabetes (T2D) has rapidly increased, along with the associated cardiovascular complications. Therefore, understanding the pathophysiology underlying T2D, the associated complications and the impact of therapeutics on the T2D development has critical importance for current and future therapeutics. The prevailing feature of T2D is hyperglycemia due to excessive hepatic glucose production, insulin resistance, and insufficient secretion of insulin by the pancreas. These contribute to increased fatty acid influx into the liver and muscle causing accumulation of lipid metabolites. These lipid metabolites cause dyslipidemia and non-alcoholic fatty liver disease, which ultimately contributes to the increased cardiovascular risk in T2D. Therefore, understanding the mechanisms of hepatic insulin resistance and the specific role of liver lipids is critical in selecting and designing the most effective therapeutics for T2D and the associated co-morbidities, including dyslipidemia and cardiovascular disease. Herein, we review the effects and molecular mechanisms of conventional anti-hyperglycemic and lipid-lowering drugs on glucose and lipid metabolism.

Antidiabetic activity of Mori folium ethanol soluble fraction (MFESF) was examined in db/db mice, which is a spontaneously hyperglycemic, hyperinsulinemic and obese animal model . 500 and 1000mg/kg dose for MFFSF (designated by SY 500 and SY 1000, respectively) and 5mg/kg dose for acarbose were administered for 6 weeks. Body weight gain, fasting and non-fasting serum glucose, glycated hemoglobin and triglyceride were all reduced dose dependently when compared between db/db control group and MFESF treated group. At 11th and 13th week after birth, MFESF increased an insulin secretion which may result in lowering serum glucose level. Total activities of sucrase and maltase in SY 500 treated group were decreased when compared to db/db control. On the other hand, those in SY 1000 and acarbose treated groups were increased. This result may suggest that proteins for sucrase and maltase were compensatorily induced due to significant inhibition of glycosidase-catalyzed reaction at doses administered in this study.

This study was designed to find out the effects of soybean protein and milk protein between nondiabetic and diabetic rats. The experimental results are summarized as follows. 1. Total food intake was higher in diabetic soybean protein group than other groups but it was not significant. 2. The change of body weight was lower in diabetic soybean protein group than other groups and the soybean protein was effective to maintain the ideal body weight. 3. The effects of lowering total cholesterol and glucose in serum was higher in soybean protein groups than the milk protein groups.
