Obesity and type 2 diabetes mellitus should be treated using a multidisciplinary approach, including diet modification, increasing physical activity, behavior modification and drug treatment. Some morbidly obese patients even require minimally invasive gastrointestinal surgery. Although in recent years minimally invasive gastrointestinal bariatric surgery in the treatment of obesity and type 2 diabetes mellitus appears to be effective, while problems exist including lack of relevant collaborative departments and multidisciplinary treatment snf low follow-up rate, which are the main reasons for poor outcomes and complications. Therefore, the management of obesity and type 2 diabetes mellitus and its co-morbidities should be minimally invasive gastrointestinal surgery, multidisciplinary treatment, and long-term follow-up.

Diabetic foot ulcers (DFUs) is a severe complication of the diabetes mellitus, which is the first leading cause of non-traumatic lower limbs amputations. The pathogenesis of diabetic foot involves a variety of mechanisms, treatment involves the department of foot and ankle surgery, department of vascular surgery, endocrinology, and infection control. Treatment need multidisciplinary diagnosis and treatment. Debridement is the basis of treating diabetic foot ulcers, and the normal anatomical structure should be maintained during the process. Vacuum sealing drainage (VSD) and antibiotic-laden bone cement (ALBC) have more advantages of controlling infection and ulceration wound healing, which could receive good clinical effect. Tendon lengthening could alleviate the problem of ulcer occurrence and progression caused by stress concentration on the bottom of foot, which has widely application and has advantages of preventing formation of foot ulcers. Flap transplantation could solve the problem of wound healing, but it is necessary to consider whether the transplanted flap could bear the same function as plantar tissue. Tibial bone transverse distraction is a relatively new technique, and the mechanism is not clear, but it has certain application prospects from the perspective of clinical efficacy.

Both obesity and diabetes impose not only individual health problems, but also large socioeconomic burdens worldwide. Obesity is a major cause of insulin resistance and diabetes and is closely linked to a series of microvascular and macrovascular complications that ultimately lead to increased morbidity and mortality. According to recent national survey data in Korea, obesity affects about 50% of adults with type 2 diabetes mellitus. Given the evidence that anti-obesity management has been beneficial in the treatment for patients with type 2 diabetes mellitus and obesity, providers should establish a strategy for weight loss for optimal, comprehensive patient management. Lifestyle intervention including diet and exercise is the cornerstone of prevention and management for obesity and type 2 diabetes mellitus. Anti-obesity drugs should be provided to those who do not respond appropriately to lifestyle intervention. Emerging data support the superiority of metabolic surgery over lifestyle or medical management for the management of type 2 diabetes associated with severe obesity. This article concisely reviews the current recommendation for lifestyle intervention including diet and exercise and pharmacological and surgical methods for obesity management in type 2 diabetic patients.

In the conventional treatments of type I diabetes, there are various problems. As a new adequate treatment of diabetes, cell replacement therapy of diabetes has been applied and given research priority. We have investigated the applications of cell transplantation in the treatment of diabetes and have retrieved the relevant articles on cells transplantation for the treatment of diabetes. In this paper, we review the history, development, merits and demerits of cell transplantation and the recent advances in pancreatic islet transplantation research. The latest progress in the induction of stem cell to differentiate into the insulin-producing cells was also introduced.

OBJECTIVETo compare the efficacy between perioperative enteral and parenteral nutrition support for esophageal cancer patients complicated with diabetes mellitus.

METHODSThirty esophageal cancer patients complicated with diabetes mellitus between September and November 2012 were prospectively enrolled in this trial. According to random number table, 30 cases were randomly divided into enteral group (n=15) and parenteral group (n=15). During the period between 3 days before operation and 8 days after operation, patients received enteral nutrition (AnSure) and parenteral nutrition support respectively. The daily dynamic monitoring of blood glucose was performed. Nutritional indexes (albumin and prealbumin) were evaluated 1-day before operation and 8-day after operation. Postoperative recovery time of gastrointestinal function and complications associated with nutritional support were observed. The cost of nutritional support was calculated.

RESULTSPatients in the two groups achieved satisfactory perioperative blood glucose control. Finger tip blood glucose was 5.0-9.0 mmol/L before meal, 7.0-10.0 mmol/L 2-hour after meal, and 4.0-8.0 mmol/L at 10 PM and 3 AM. No hypoglycemia (<3.5 mmol/L) was found in all the patients. The time to first flatus after surgery was (62.4±15.7) in the enteral group, significantly earlier than (90.8±22.4) h in the parenteral group (P<0.01). Postoperative nutritional indices and associated complications were not significantly different between two groups (all P>0.05). Cost in the enteral group was significantly lower than that in the parenteral group [(650.8±45.8) RMB vs. (3016.5±152.6) RMB, P<0.01].

CONCLUSIONPerioperative nutrition support can effectively control blood glucose and improve perioperative nutritional status simultaneously for esophageal cancer patients with diabetes mellitus. Compared with parenteral nutrition, enteral nutrition can accelerate the recovery of gastric bowel function and reduce the cost of nutritional support.

Islet transplantation has the potential to restore normoglycemia and prevent the development of diabetic complications such as retinopathy, nephropathy and neuropathy, and could therefore ve a valuable treatment for diabetic patients. The scarcity of available islets is an obstacle for clinically successful islet transplantation. To resolve the problems, we have examined the two methods, islet transplantation with extracellular matrix1 and in vivo expansion of islets with electrically- transfection of growth factors.

OBJECTIVETo observe the influence of negative pressure wound therapy on the angiogenesis of wounds in diabetic rats.

METHODSDiabetes model was reproduced by intraperitoneal injection of 20 g/L streptozotocin in the dosage of 65 mg/kg in 40 SD rats. Two weeks later, rats were divided into control group (C) and negative pressure group (NP) according to the random number table, with 20 rats in each group. A piece of full-thickness skin in the center of the back of each rat in the size of 2 cm×2 cm was excised to produce a wound. Immediately after injury, wounds in group C were given conventional dressing change; wounds in group NP were treated with continuous negative pressure (-16.0 kPa) therapy for four hours a day, which lasted for seven days. (1) Blood glucose and body weight of rats in two groups were respectively measured by glucose meter and electronic scale before treatment, and 1 and 2 week (s) after. (2) Wound blood flow was detected by laser Doppler perfusion imager before treatment and on post treatment day (PTD) 1, 3, 7, with 5 rats at each time point. (3) On PTD 3 and 7, respectively, five rats from each group were sacrificed. The wound tissue was excised and divided into two parts. The angiogenesis in the left part tissue was observed with immunohistochemical staining. The microvessel density was calculated. (4) The full-thickness skin excised before treatment and the right part tissue freeze on PTD 3 and 7 were collected. On PTD 1 and 14, wound tissue was excised in the above-mentioned method. The mRNA levels of the vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor 1 (Fit-1), angiopoietin 1 (Ang-1), Ang-2, and tyrosine kinase receptor 2 (Tie-2) were determined with real-time fluorescence quantification PCR. Data were processed with two-way analysis of variance or LSD-t test.

RESULTS(1) No significant difference was observed between two groups in blood glucose level and body weight as a whole or at each time point (with F values respectively 0.667, 0.176, t values from 0.311 to 0.707, P values all above 0.05). (2) The difference in the overall wound blood flow of rats between two groups was significant (F = 24.66, P < 0.05). On PTD 1, 3, 7, values of wound blood flow of rats in group NP were (179 ± 24), (219 ± 12), (192 ± 30) perfusion unit, significantly higher than those of rats in group C[(127 ± 16), (179 ± 8), (144 ± 17) perfusion unit, with t values respectively 3.71, 5.57, 2.77, P < 0.05 or P < 0.01]. (3) The difference in the overall microvessel density in the wound of rats between two groups was significant (F = 33.25, P < 0.05). On PTD 3, the microvessel density in the wound of rats in group NP was (80 ± 12) per 100-time visual field, which was significantly higher than that of group C[(38 ± 4) per 100-time visual field, t = 9.257, P < 0.05]. On PTD 7, the microvessel density in the wound of rats in two groups were close (t = 1.159, P > 0.05), but the vessels in group NP were regularly arranged with spacious lumen, while the vessels in group C were disorderly arranged with narrow lumen. (4) On PTD 1, 3, mRNA expression levels of VEGF, Fit-1, and Ang-1 in group NP were obviously higher than those in group C (with t values from 1.28 to 11.60, P values all below 0.01). On PTD 7, the mRNA expression level of Ang-1 (27.59 ± 3.55) in group NP was obviously higher than that in group C (19.87 ± 1.86, t = 7.23, P < 0.001), while the mRNA level of its antagonist Ang-2 (5.79 ± 0.61) in group NP was obviously lower than that in group C (17.62 ± 0.85, t = 19.88, P < 0.001). On PTD 3, 7, 14, mRNA levels of Tie-2 in group NP were obviously lower than those in group C (with t values from 8.92 to 15.60, P values all below 0.01).

CONCLUSIONSNegative pressure wound therapy may promote wound angiogenesis by enhancing the expression of Ang-1 and lowering the expression of Ang-2 in diabetic rats.

Necrotizing fasciitis is known to be a highly lethal infection of deep-seated subcutaneous tissue and superficial fascia. Reports of necrotizing fasciitis due to Streptococcus pneumoniae are exceedingly rare. We report a case of necrotizing fasciitis in a 62-yr-old man with liver cirrhosis and diabetes mellitus. He presented with painful swelling of left leg and right hand. On the day of admission, compartment syndrome was aggravated and the patient underwent surgical exploration. Intra-operative findings revealed necrotizing fasciitis and cultures of two blood samples and wound aspirates showed S. pneumoniae. The patient died despite debridement and proper antimicrobial treatment. To the best of our knowledge, this is the first case of fatal necrotizing fasciitis with meningitis reported in Korea. We also review and discuss the literature on pneumococcal necrotizing fasciitis.
