Vascular inflammatory process has been suggested to play a key role in initiation and progression of atherosclerosis, a major complication of diabetes mellitus. Thus, in this study, we attempted to determine whether three structurally related polyphenols found in the Chinese herb Huang Qui, namely baicalin, baicalein, and wogonin, can suppress vascular inflammatory processes induced by high glucose (HG) in human umbilical vein endothelial cells (HUVECs) and mice. Data showed that HG induced markedly increased vascular permeability, monocyte adhesion, expressions of cell adhesion molecules (CAMs), formation of reactive oxygen species (ROS) and activation of nuclear factor (NF)-κB. Remarkably, all of the above mentioned vascular inflammatory effects of HG were attenuated by pretreatment with baicalin, baicalein, and wogonin. Vascular inflammatory responses induced by HG are critical events underlying development of various diabetic complications, therefore, our results suggest that baicalin, baicalein, and wogonin may have significant therapeutic benefits against diabetic complications and atherosclerosis.

Diabetes mellitus has become a major growing public health problem worldwide. More than 90% of all diabetes cases are classified as type 2 diabetes (T2D), which is also known as non-insulin dependent diabetes. Protein tyrosine phosphatase 1B (PTP1B) plays an important role in the negative regulation of insulin signal transduction pathway and has emerged as novel therapeutic strategy for the treatment of type 2 diabetes. PTP1B inhibitors enhance the sensibility of insulin receptor (IR) and have favorable curing effect for insulin resistance-related diseases. Recently twelve anti-diabetic xanthones were isolated from the bark of Garcinia xanthochymus. Hence, in the present study, molecular docking was carried out for these twelve xanthones. The objective of this work is to study the interaction of the newly isolated xanthones with PTP1B. The docking results showed that xanthones have good interactions and has better docking score with PTP1B and suggest LYS120 and ASP181 are the important residues involved in interaction between PTP1B enzyme and the xanthones.

Purpose: To provide baseline data for prevention and education of diabetic foot in Korea. Materials and Methods: 216 diabetic patients are included in this survey. The average age is 58.64 year old with average 9.92 years of diabetes mellitus periods. Among them, 41% used insulin injection, 42% oral medication, 14% both and 3% diet were used for their blood sugar control. The diabetic foot survey was done. Results: The survey of patients symptom and disease of their feet results: 49% had sensory decrease in their feet. Associated disease in foot were callus(15%), heel pain(10%), bunion(4%), toe deformity(2%), Tinea pedis were 9%, tingle sensation were 17%, and swelling on feet were 2%, The survey of patients privious history of foot problems are: 8% had previous operation history on their feet and 17% had history of infection on their feet, 23% had bullae history, The survey of patients prevention and education are: Those who have had more than one diabetic foot education were 45.7%, and among them 24% had routine regular foot check up. Only 5% wear special diabetic shoe and 3% had custom orthotics. Conclusion: Interests to diabetic foot care is increasing in diabetic patients in Korea. However still we need more education, and efforts for prevention. Special education and diabetic shoe is still low, The survey data could be good baseline for diabetic prevention and education.

Diabetic Ketoacidosis(DKA), one of acute complications of diabetes mellitus(DM) occurs mostly in insulin dependent diabetes mellitus (IDDM) patients. Its clinical symptoms are hyperglycemia, ketonemia or ketonuria, metabolic acidosis, etc. The interaction of lack of insulin, excessive secretion of insulin antagonic hormone and dehydration cause body fluid loss and electrolyte, typical symptom of DKA as polyuria, polydipsia, nausea, vomiting, abdominal pain occur. As a result, prompt supply of fluid and insulin by intravenous injection should be conducted for treatment. It is still an emergent disorder whose mortality is still 10 to 15%, though is has decreased compared to the past. We treated a female patient who has DKA, had withdrawn insulin pump therapy. We report a case of DKA with a brief review of related literatures.

Diabetes mellitus (DM) is one of the highest morbidity and mortality diseases and is a state of increased oxidative stress. This study was carried out to evaluate anti-oxidant activities of Hovenia dulcis Thunberg in streptozotocin (STZ)-induced diabetic rats. Eighty Sprague-Dawley rats, 6 week-old, were divided into 3 groups at 12hours after STZ induction; Diabetic control group (DW per os DC group), Glibencliamide group (5 mg/kg glibenclimide per os, GLI group) and Hovenia dulcis group (100 mg/kg Hovenia dulcis Thunberg water extract per os HDT group). Normal control group (NC group) was just injected with DW instead of STZ. On day 5, superoxide dismutase (SOD) and catalase activities of HDT group were significantly (P < 0.05) increased compared with DC group and glutathione peroxidase activities of HDT group was more increased than DC group but there was no significant difference.

Purpose: The purpose of this study was to investigate the depression, anxiety, stress response and self-care, to analyze the correlation among depression, anxiety, stress response and self-care by gender, and to determine factors associated with self-care in diabetic patients. Method: The subjects of this study were 103 participants with diabetes mellitus. Data were analyzed by chi-square test, t-test, Pearson correlation coefficient and multiple regression analysis by using SAS program. Result: Items for self-care evaluation by gender were significant differences in hospital visit, hypoglycemia preparation, proper hygiene, taking a rest, foot injury check, drinking, and smoking. The female patients are more likely to have higher self-care score than the male patients. However, there were no differences in depression, anxiety and stress response by gender. In male patients, there were positive correlations between the degree of depression and stress response, the degree of anxiety and stress response. In female patients, there were positive correlations between the degree of depression and stress response, the degree of anxiety and stress response. In multiple regression analysis, gender and experienced admission is associated with self-care. Conclusion: We should consider integrated approaches for psychological problems in the management of diabetic patients.

Purpose: Diabetes mellitus is a clinically and genetically heterogeneous group of metabolic disorders manifested by abnormally high levels of glucose in the blood. Mounting evidence demonstrates that diabetes is a risk factor for gingivitis and periodontitis. The circulating mononuclear phagocytes in diabetic patients with hyperglycemia are chronically exposed to high level of serum glucose. Thus, this study attempted to determine the effect of pre-exposure of monocytes and macrophages to high concentration of glucose on lipopolysaccharide (LPS)-induced production of pro-inflammatory mediators. Material and Methods: For this purpose, cells were cultured in medium containing normal (5 mM) or high glucose (25 mM) for 4-5 weeks before treatment for 24 h with LPS. LPS was highly purified from Porphyromonas gingivalis or Prevotella intermedia by phenol extraction. Result: Results showed that prolonged pre-exposure of cells to high glucose markedly increased LPS-stimulated NO secretion when compared to normal glucose. In addition to NO, high glucose also augmented LPS-stimulated IL-6, IL-8, and TNF-$\alpha$ secretion after cells were exposed to high glucose for 4 weeks. Conclusion: The present study demonstrates that pre-exposure of mononuclear phagocytes with high glucose augments LPS-stimulated production of pro-inflammatory mediators. These findings may explain why periodontal tissue destruction in diabetic patients is more severe than that in non-diabetic individuals.

The role of surgical intervention in patients with diabetic gastroparesis is unclear. We report a case of a 37-year-old man with a history of recurrent episodes of vomiting and long-standing type 2 diabetes mellitus. Esophagogastroduodenoscopy did not reveal any findings of reflux esophagitis or obstructive lesions. A gastric emptying time scan showed prolonged gastric emptying half-time (344 minutes) indicating delayed gastric emptying. Laboratory tests revealed elevated fasting serum glucose and glycosylated hemoglobin (HbA1c, 12.9%) and normal fasting C-peptide and insulin levels. We performed Roux-en-Y reconstruction after subtotal gastrectomy to treat gastroparesis and improve glycemic control, and the patient showed complete resolution of gastrointestinal symptoms postoperatively. Barium swallow test and gastric emptying time scan performed at follow-up revealed regular progression of barium and normal gastric emptying. Three months postoperatively, his fasting serum glucose level was within normal limits without the administration of insulin or oral antidiabetic drugs with a reduced HbA1c level (6.9%). Long-limb Roux-en-Y reconstruction after subtotal gastrectomy may be useful to treat severe diabetic gastroparesis by improving gastric emptying and glycemic control.
