ABSTRACT
Objective To explore the influence of modified radical gastrectomy on glycometabolism in patients with gastric carcinoma and non-obese T2DM.Methods The retrospective study was carried out to analyze the changes of glycometabolism between preoperative and postoperative follow-up in 25 patients with gastric carcinoma and non-obese T2DM.The above parameters included fasting plasma glucose (FPG),2-hour postprandial blood glucose (2 h PBG),glycosylated hemoglobin A1c (HbA1c),fasting insulin (FINS),homeostasis model assessment-insulin resistance (HOMA-IR),fasting glucagon-like peptide-1 (GLP-1),and glucose-dependent insulinotropic polypeptide (GIP).Results At the 6th and 12th month after operation,the related parameters such as FPG,2 h PBG,HbA1c,FINS and HOMA-IR were (7.54±1.44) mmo]/L and (7.17±1.35) mmol/L,(9.97±1.59)mmol/L and (9.47±1.23) mmol/L,(6.46±0.74)％ and (6.31±0.97)％,(7.73±0.98) μIU/ml and (7.44±0.96) μIU/ml,1.10±0.15 and 1.04±0.14 respectively.The above indexes were significantly improved compared with those before operation (P＜O.05).The levels of fasting GLP-1 at 6th and 12th month after operation were (2.27±0.25) pmol/ml and (2.33±0.27) pmol/ml respectively,and there was no significant change compared with those before operation (P＞0.05).On the contrary,the levels of GIP at 6th and 12th month after operation are significantly decreased compared with that before operation,which were (7.23±1.33) pmol/ml and (6.40±1.20) pmol/ml respectively.Conclusion The modified radical gastrectomy can improve T2DM in patients with gastric carcinoma markedly,even curing some patients,which may be related to the decrease of fasting GIP after operation.
ABSTRACT
Objective To investigate the level changes of plasma insulin,serum lipids in type 2 diabetes with cholelithiasis.Methods 159 cases of types 2 diabetic patients was studied during recently 3 years in our department of endocrinology,the levels of blood glucose,plasma insulin and insulin sensitivity index(ISI),serum lipids,apolipoproteins(ApoA 1,B) were measured both fasting and post-prandial,and investigated their correlation between type 2 diabetic patients with cholelithiasis(n=103) and without cholelithiasis(n=56).Results Female was predominated in fifty-six diabetic with cholelithiasis,they had higher triglyceride(TG),fasting or post-prandial insulins,ApoA 1,ApoB,the top body weight index and lower ISI than 103 diabetics without cholelithiasis.There were no significant differences in total cholesterol(CH),HDL-Ch,LDL-Ch,blood glucose concentrations between the groups.Conclusions Obesity,insulin resistance and lipids metabolic disturbance might be related to the development of cholelithiasis in type 2 diabetic patients.
