ABSTRACT
Objective To evaluate effect of intensive insulin treatment(IIT)on healthcare-associated infection (HAI)rate in patients with acute stroke and stress hyperglycemia.Methods Databases,including PubMed,Em-base,Cochrane Library,WanFang,and China National Knowledge Infrastructure(CNKI)Data,were electronically searched,relevant journals and references of the included literatures were also searched manually,literatures were selected according to the uniform inclusion and exclusion criteria,incidence of HAI and mean blood glucose in patients who received IIT for acute stroke were assessed systematically.Results A total of 13 randomized controlled trials (RCT)involving 1 032 patients were included in this systematic review.Meta-analysis results showed that 10 studies involving 832 patients were finally enrolled for comparing HAI rate, HAI rates in IIT group and conventional insulin treatment group were 28.3% and 56.1 %,respectively(Z =4.50 ),difference between two groups was statistically significant (RR=0.53 [95 %CI :0.40 to 0.70],P <0.001 );A total of 328 patients in 5 studies were finally included in the comparison of blood glucose,difference in mean blood glucose between two groups was statistically significant(MD =-2.52 [95% CI :-4.30 to -0.74],P =0.006).Funnel plot of HAI rate revealed that there was publication bias.Conclusion IIT is used for the regulation of stress hyperglycemia in acute stroke,it can reduce the incidence of HAI and blood glucose in patients.
ABSTRACT
Objective To study the effect of transient intensive insulin treatment on the serum free fatty acid (FFA) in newly diagnosed type 2 diabetic patients.Methods Sixty-four newly diagnosed type 2 diabetic patients were treated with transient intensive insulin.The fasting plasma glucose (FPG),2 hours post-prandial glucose (2hPG),lipid,fastin insulin (FINS),and serum FFA was examined hefore and after treatment.Results The levels of FPG,2hPG,total cholesterol (TC),triglycerides (TG),low density lipoproteins cholesterol (LDL-C),FFA and HOMA-IR after treatment were (9.68 ± 2.02) mmol/L,(12.77 ± 1.35) mmol/L,(4.26 ± 1.07) mmol/L,(1.52 ± 0.58) mmol/L,(2.50 ±0.75) mmol/L,(435.84 ± 190.94) μmol/L,0.51 ± 0.62,and they decreased obviously compared with those before treatment [(14.66 ± 3.50) mmol/L,(17.43 ±4.89) mmol/L,(5.03 ±0.94) mmol/L,(2.05 ± 1.42) mmol/L,(2.91 ±0.78) mmol/L,(586.68 ±229.45)μmol/L,0.65 ± 0.89](P＜0.05).The level of HOMA-β increased obviously (2.70 ± 0.83 vs.1.74 ± 1.04)(P＜0.05).The increase of HOMA-β and the decrease of HOMA-IR was positively correlated with the decrease of FFA.Conclusion The transient intensive insulin treatment can evidently decrease the level of FFA that can improve beta-cell function and relieve insulin resistance in newly diagnosed type 2 diabetic patients.
ABSTRACT
Objective To observe the effects of intensive insulin treatment on islet β cell apoptosis associated protein bcl-2 and bax in type 2 diabetic rats.Methods 36 Wistar rats were randomly divided into two groups : normal control group and high fat diet group.Rats in normal control group fed by basical feedstuff.Rats in high fat diet group fed by high fat and basical feedstuff.After 10 days,rats in high fat group were injected with STZ.After 3 days,rats in high fat group were randomly divided into two groups:diabetes control group and insulin treatment group.The course of treatment was 4 weeks.After 10 days by fat milk intragastfic administration, after 3 days of STZ injection and after 4 weeks treatment, each index was measured.After experiment, pancreatic tissue bel-2 and bax were detected through immunohistocbemical method.Results After 4 weeks intensive insulin treatment,the bcl-2 was significantly increased at(6.20 ± 2.05 )% in insulin treatment group than diabetes control group.The bax was significantly decreased at ( 2.68 ± 1.04 ) % in insulin treatment group than diabetes control group ( P < 0.05 ).Conclusion The method of insulin intensive treatment could increase islet βcell bcl-2 and decrease bax in type2 diabetic rots, Insulin intensive treatment could decrease islet β cell apoptosis.
ABSTRACT
Objective To research the effects of short-term intensive insulin treatment on regaining the sensitivity of sulfonylureas in diabetes patients. Methods Thirty patients from outpatient and emergency department,including 12 male and 18 female,who took regular-dose sulfonylureas but was high blood glucose level,were selected to suspend the sulfonylureas treatment and were given the BIAsp30 to control the blood glucose level for three months,then they were stopped the BIAsp30 and took the same sulfonylureas used before.Results The average fasting blood glucose(FBG) was(9.4?7.5)mmol/L and the average postprandial 2 h blood glucose(PG2h)(or random blood glucose) was(14.2?7.2)mmol/L in 3 months before stopping the sulfonylureas.The average FBG was(5.7?0.7)mmol/L and PG2h was(7.2?1.4)mmol/L at the beginning of the insulin getting the blood glucose under control.The average FBG was(6.0?0.8)mmol/L and PG2h was (7.8?1.2)mmol/L during the insulin treatment.The average FBG was(6.1?0.6)mmol/L and PG2 h was(7.7?1.3)mmol/L at the end of the insulin treatment.The average FBG was(6.5?0.5)mmol/L and PG2h was(8.1?(0.8))mmol/L when continuing the sulfonylureas treatment in one months.It increased significantly to compare the blood glucose before the treatment of insulin to that after the treatment of insulin(P
ABSTRACT
0.05);The levels of basal FINS showed a significant differences between group A and group B(P0.05).Conclusions Intensive insulin treatment to newly diagnosed type 2 diabetes patients can control blood glucose rapidly to a desired level,and can recover the function of B cell better than traditional oral hypoglycemic agents by dissolving the virulence of glucose rapidly.
ABSTRACT
Forty-one type 2 diabetic patients with fasting plasma glucose≥15 mmol/L and postprandial plasma glucose≥16.8 mmol/L underwent short-term intensive insulin treatment (IIT). Glucose load tests were performed before and after treatment in these patients and proinsulin and C peptide were assayed by RIA. The results showed that IIT decreased the levels of fasting and postprandial proinsulin and improved the ? cell function.
ABSTRACT
Objective To investigate the predictors of long-term remission of type 2 diabetes induced by short-term intensive insulin treatment.Methods Fifty-four cases of diabetes mellitus with the duration of illness less than 5 years received an intensive insulin treatment for 2 weeks.The standard meal test and intravenous glucose tolerance test were performed at the baseline and 24 h after treatment completion respectively.Long-term remission meant that the diabetic patients should maintain the target glyeaemic control without any hypoglyeaemie agent within one year.Results The remission rate was 57.4% (31/54) overall,and even reached to 80.6% (29/36) in patients with the duration of illness less than 6 months,whereas,the remission rate was only 11.1% (2/18) in those with the duration of illness more than 12 months.In another view,the remission rate was significantly higher in the patients with fasting plasma glucose (FPG) level of less than 7 mmol/L (78.8%,26/ 33) 24 h after intensive treatment than those with FPG level of more than 7 mmol/L (23.8%,5/21,P
