ABSTRACT
Objective To investigate the effects of acarbose versus fenofibrate on insulin secretion and insulin resistance in the subjects with impaired glucose tolerance (IGT) and hypertriglyceridemia. Methods Eighty subjects were allocated to acarbose group (28 cases),fenofibrate group (30 cases),and control group (22 cases) without intervention for 3 months,and also divided into elderly (46 cases) and younger groups (34 cases). Fasting blood samples were collected for measuring fasting plasma glucose and lipid.Oral glucose tolerance test (OGTT) were carried out with measurement of plasma insulin and glucose before ad after treatment.Early insulin secretion indexes(△I30/△G30),insulin secretion indexes (HOMA -β) and insulin resistance indexes (HOMA-IR)were calculated. Results After 3-months of treatment,the lipid profile was evidently improved in fenofibrate group. Levels of triglyceride (TG) and total cholesterol (TC) were significantly reduced ( both P ＜ 0.01 ),△I30/△G30 was significantly increased (P ＜ 0.05) and HOMA-IR was decreased (P＜＜0.01).In acarbose group,levels of fasting plasma glucose (FPG),2hours postprandial plasma glucose (2 hPG) and HOMA-IR were reduced (all P＜0.01),△I30/△G30 and HOMA-β were enhanced (P＜0.01 or P＜0.05).No change of above indicators was found in the control group.Compared with fenofibrate group,acarbose group had higher △ I30/△G30 (P＜ 0.05),HOMA-β (P＜ 0.01 ) and lower HOMA-IR ( P ＜ 0.01 ).The improvement of △△I30/△G30 was correlated with the decreasing of plasma FPG,2 hPG and TG(r=0.5812,0.6327,0.3872,P＜0.01),while HOMA-1R was related with the decreasing of plasma 2 hPG,TG and TC(r=0.8126,0.4671,0.2895,P＜ 0.01). HOMA-IR,△I30/△G30 and HOMA-β were lower (P＜0.01) and acarbose improved insulin resistance better (P＜0.05) in the elderly than in the younger with type 2 diabetes. Conclusions Pancreatic β-cell function declines gradually with aging,acarbose may have advantage over fenofibrate in improving early insulin secretion and resistance which was more relieved by diminishing glucotoxity in comparison with lipotoxity.
ABSTRACT
Objective To explore the changes of cardiac structure and funetion in the patients with type 2 diabetes mellitus(T2DM).Methods Thirty T2DM patients were included in the study,color Doppler echocardiography was performed in all of the cases,to compare and analyze the results of cardiac structure and function.Results IVS,LVPW,LAD,LVM of T2DM group were significantly larger than those in healthy group(P＜0.05,P＜0.01).T2DM group of LVEF and E/A ratio were significantly lower than those of normal group(P＜0.05).BMI,FBG,TG were positive correlation with IVS,LVPW,LVM and negative correlation with LVEF,E/A.Conclusion The patients of T2DM can lead to change of cardiac structure and function which dependent with BMI and glucose degree.
ABSTRACT
[Objective]To assess the clinical effect and radiological results of three methods of anterior cervical decompression and reconstruction for the treatment of multilevel cervical myelopathy.[Method]Fifty-two patients with continuous multilevel cervical myelopathy treated by the same team were divided into three groups.Group Ⅰ was performed the twosegment-corpectomy and reconstructed with a long titanium mesh and plate.Group Ⅱ was performed the three-level-discectomy and fused with three cages.Group Ⅲ was performed the combination with corpectomy and discectomy.The parameters included intervertebral height,JOA score.The data was compared statistically with Student s T-test or ANOVA.[Result]JOA score in all groups was improved post operation,but there was no significant difference among the three groups.The post-operation intervertebral height lose of group Ⅰ was more significant than other two groups,three cases of titanium meshs subsidence happened in group Ⅰ and one same case happened in group Ⅲ.[Conclusion]All the three surgical methods of anterior decompression and fusion can procure wonderful clinical effect,but group Ⅱ and Ⅲ were better than group Ⅰ in the stability and the maintenance of intervertebral height post operation.
