RÉSUMÉ
Objective To explore the effect of intermittent fasting on blood glucose control in patients with type 2 diabetes mellitus(T2DM)complicated by overweight and obesity.Methods 46 T2DM patients with overweight and obesity were divided into control group(Con,n=22)and intermittent fasting group(IF,n=24)according to their wishes.Con group was given routine diet and drug treatment by specialists in endocrinology.IF group completed the intermittent fasting by using a combination of meal replacement and natural diet,and hypoglycemic drugs were reduced on fasting days.Results Compared with Con group,IF group showed a significant decrease in body weight,BMI,hypoglycemic drug efficacy score,WC,fat index,hip circumference and visceral fat(VF)(P＜0.05).After intervention,the proportion of diabetes in remission or near remission in IF group was higher than that in Con group(P＜0.05).Conclusion Intermittent fasting can reduce the application of hypoglycemic drugs in T2DM patients with overweight and obesity,and can also reduce weight and VF.
RÉSUMÉ
Objective To study whether preoperative serum thyrotropin ( TSH) concentration can be used for risk prediction of papillary thyroid microcarcinoma ( PTMC ) . Methods The cohort of this retrospective study consisted of 1 707 patients who underwent surgery on thyroid nodules at Chinese PLA General Hospital from October 1999toFebruary2011. 37.32%(n=637)ofthesepatientssufferedfromdifferentiatedthyroidcancer(DTC),and 14. 18%(n=242) of patients with DTC suffered from PTMC. Results (1) The mean TSH level in patients with DTC was significantly higher than that in patients with benign thyroid nodules [(1. 99(1. 25-3. 19) vs 1. 48 (0. 85-2. 32) mU/L, P<0. 01]. DTC with diameter greater than 10 mm had higher serum TSH level compared with that in benign thyroid nodules[2. 04(1. 26-3. 36) vs 1. 45(0. 83-2. 30), P<0. 01]. Serum TSH level was not significantly raised in cases where-as the diameter of tumor was 10 mm or less. (2) With the increasing level of TSH, the prevalence of DTC and tumours with diameter greater than 10 mm rose significantly, but the increasing trend was not significant in PTMC. (3) Raised TSH level was an independent risk factor of DTC based on Binary logistic regression. Conclusions Serum TSH is an independent risk predictor of DTC, it is an independent risk predictor of the diameter of DTC greater than 10 mm, but it is not a good risk predictor in PTMC.
