Hyperglycemia can result in severe adverse effects on the body. The mortality and morbidity of surgery are increased significantly in diabetic patients. The surgical stress-related hyperglycemia and insulin resistance can also produce the same adverse consequences. The metabolic state of the surgical patients, anesthesia method, glucose infusion, stress-induced neuroendocrine responses and insulin resistance can affect the perioperative blood glucose levels, resulting in poor clinical outcomes. The relationship between tight glycemic control and reducing post-operative mortality and morbidity is not clear. It's necessary to control blood sugar level during the perioperative period but the ideal state of glycemic control still needs a mult-center clinical trial evidence. It is generally believed that perioperative blood glucose level should be controlled below 10 mmol/L. The efficacy and safety of tight glycemic control needs further study.

OBJECTIVETo analyze the mechanism of neuroprotection of insulin and which blood glucose range was benefit for insulin exerting neuroprotective action.

DATA SOURCESThe study is based on the data from PubMed.

STUDY SELECTIONArticles were selected with the search terms "insulin", "blood glucose", "neuroprotection", "brain", "glycogen", "cerebral ischemia", "neuronal necrosis", "glutamate", "γ-aminobutyric acid".

RESULTSInsulin has neuroprotection. The mechanisms include the regulation of neurotransmitter, promoting glycogen synthesis, and inhibition of neuronal necrosis and apoptosis. Insulin could play its role in neuroprotection by avoiding hypoglycemia and hyperglycemia.

CONCLUSIONSIntermittent and long-term infusion insulin may be a benefit for patients with ischemic brain damage at blood glucose 6-9 mmol/L.

Epidemiologic studies have revealed diabetes mellitus is an important determining factor not only for the presence of peripheral arterial disease (PAD) but also for the severity of PAD. As PAD is closely related to mortality and morbidity in individuals with diabetes as well as the general population, the primary prevention for PAD is very important. Age, disease duration, the level of hyperglycemia, blood pressure, and smoking status are independent risk factors for development of PAD in diabetic patients, and management of those risk factors might be an effective tool for reducing PAD burden.

Stroke ranks as one of the leading causes of death and the most common cause of permanent disability in adults in Korea. Timely recognition and treatment is imperative to reduce stroke-related morbidity and mortality. Patients with acute ischemic stroke should be evaluated for intravenous thrombolysis with recombinant tissue-plasminogen activator (rt-PA); antiplatelet drugs can be administered to those who do not qualify for rt-PA therapy. Adequate hydration and correction of possible hypoxia are necessary, and hyperglycemia and fever should be treated aggressively. Blood pressure management should be individualized on the basis of stroke pathophysiology. It is important to prevent and manage complications of acute stroke, such as pneumonia, urinary tract infection, bed sore, deep vein thrombosis, and joint contracture. Meticulous evaluation of etiology of ischemic stroke can determine the most appropriate acute management and would guide the secondary prevention of stroke.

Hyperglycemia significantly increases the risk of cardiovascular disease (CVD) in diabetics. However, it has been shown by a series of large scale international studies that intensive lowering of blood glucose levels not only has very limited benefits against cardiovascular problems in patients, but may even be harmful to patients at a high risk for CVD and/or poor long-term control of blood glucose levels. Therefore, Western medicine is faced with a paradox. One way to solve this may be administration of Chinese herbal medicines that not only regulate blood glucose, blood fat levels and blood pressure, but also act on multiple targets. These medicines can eliminate cytotoxicity of high glucose through anti-inflammatory and anti-oxidant methods, regulation of cytokines and multiple signaling molecules, and maintenance of cell vitality and the cell cycle, etc. This allows hyperglycemic conditions to exist in a healthy manner, which is called "harmless hyperglycemia" Furthermore, these cardiovascular benefits go beyond lowering blood glucose levels. The mechanisms of action not only avoid cardiovascular injury caused by intensive lowering of blood glucose levels, but also decrease the cardiovascular dangers posed by hyperglycemia.

OBJECTIVETo study the clinical effect and safety of early postnatal application of glucocorticoids in the prevention of bronchopulmonary dysplasia (BPD) in preterm infants.

METHODSThe databases including PubMed, Cochrane Library, Embase, CNKI, Wanfang Data, and VIP were comprehensively searched for articles on early postnatal application of glucocorticoids in the prevention of BPD in preterm infants published up to June 2016. Review Manager 5.3 was used for the Meta analysis of 16 randomized controlled trials (RCTs) that met the inclusion criteria.

RESULTSA total of 2 962 participants were enrolled in the 16 RCTs, with 1 486 patients in the trial group and 1 476 in the control group. The Meta analysis showed that early postnatal application of glucocorticoids reduced the incidence rate of BPD at a corrected gestational age of 36 weeks (OR=0.73, 95%CI: 0.61-0.87, P=0.0004), but there was an increase in the risk of hyperglycemia (OR=1.61, 95%CI: 1.24-2.09, P=0.0003), hypertension (OR=1.63, 95%CI: 1.11-2.38, P=0.01), and intestinal perforation (OR=1.51, 95%CI: 1.12-2.04, P=0.007).

CONCLUSIONSAt present, it is not recommended to use glucocorticoids to prevent BPD in preterm infants. Its advantages and disadvantages need further studies, with special focuses on the adverse effects of hyperglycemia, hypertension, and intestinal perforation.

The rising incidence and prevalence of diabetes along with its complications have become a global concern. The necessity for a comprehensive model-targeting primary, secondary and tertiary prevention as well as all levels of care has become apparent. Staged Diabetes Management (SDM) was developed over a decade ago by the International Diabetes Centers, Minneapolis, Minnesota, U.S.A.. SDM was founded on the principle that a detailed understanding of the natural history of diabetes and the underlying defects responsible for the development of hyperglycemia and its associated complications should be the basis of sound clinical decision-making. It relies on clinical pathways to guide the clinicians though the detection, treatment and follow up of each type. Unique to SMD is that each pathway is customized for utilization in collaboration with local physicians and allied heath professionals. Thus far clinicians from 22 countries, using 11 translated versions of SDM, have participated in this process. In Korea, SDM was introduced in 1999 with the foundation of the committee in Korean Diabetes Association (KDA). Taking into account the regional difference in medical practice, resource allocation, availability of pharmacological agents and access to care, this Korean version of SDM was developed to reduce variation in practice, improve screening and detection, tighten glycemic control and to increase surveillance of complications. It has been noted that diabetes contributes to the cost of medical services. One way of reducing the financial burden is to find cost-effective approaches to prevention, detection and treatment of diabetes and its complications. The SDM model directly addresses this issue by seeking ways to optimize the limited resources available for diabetes care, prioritizing treatment, reducing medical error and expanding the role of allied health professionals. As SDM moves into the 21st century, its mission has expanded to encompass the principles of primary and secondary prevention.

OBJECTIVE: To evaluate the effect of different control levels of glucose on the serum lactic acid during operation, and to investigate the relation between glucose and lactic acid to find a new way of myocardial protection. METHODS: Volunteers were divided into an experiment group(n=38) and a control group(n=33) by random sampling and double blind method. The experiment group received intensive insulin therapy and the control group received traditional therapy. The arterial blood gas samples of all the patients at different time points after the operation were harvested in the intensive care unit for blood gas analysis. The related data were collected and analyzed. RESULTS: The serum glucose level in the 2 groups decreased firstly, then increased, and recovered finally. The serum lactic acid level in the 2 groups increased firstly, decreased later, then reincreased, and recovered finally. The highest level of the serum lactic acid was found 2 hours after the operation. There were significant differences in serum glucose and lactic acid levels at 2, 12, and 24 h after the operation in the two groups (P<0.01). The other data were not significant (P>0.05). CONCLUSION The variation of serum glucose and lactic acid level at 2, 12, 24 h after the valve replacement is consistent and significant. The serum lactic acid in the serum may be decreased by controlling the blood glucose, which provides experiment basis for myocardial protection.

Cancer incidence appears to be increased in both type 1 and type 2 diabetes mellitus (DM). DM represents a risk factor for cancer, particularly hepatocellular, hepatobiliary, pancreas, breast, ovarian, endometrial, and gastrointestinal cancers. In addition, there is evidence showing that DM is associated with increased cancer mortality. Common risk factors such as age, obesity, physical inactivity and smoking may contribute to increased cancer risk in patients with DM. Although the mechanistic process that may link diabetes to cancer is not completely understood yet, biological mechanisms linking DM and cancer are hyperglycemia, hyperinsulinemia, increased bioactivity of insulin-like growth factor 1, oxidative stress, dysregulations of sex hormones, and chronic inflammation. However, cancer screening rate is significantly lower in people with DM than that in people without diabetes. Evidence from previous studies suggests that some medications used to treat DM are associated with either increased or reduced risk of cancer. However, there is no strong evidence supporting the association between the use of anti-hyperglycemic medication and specific cancer. In conclusion, all patients with DM should be undergo recommended age- and sex appropriate cancer screenings to promote primary prevention and early detection. Furthermore, cancer should be screened in routine diabetes assessment.
