ABSTRACT
Objective To describe an ideal technique to repair full-thickness lower lid marginal defects in a one-stage procedure. Methods The buccal rotation flap and the nasal septal chondromucosal flap were used in one-stage operation to repair full-thickness lower eyelid defect. Results Eleven patients including 6 male patients and 5 female patients underwent lower eyelid reconstruction since January 2000.The age ranged from 29 to 64 years with average 43. Seven patients with full-thickness lower eyelid defect were caused by basal cell carcinoma excision, while four patients were caused by trauma. All the fullthickness lower eyelid defects were reconstructed by using the buccal rotation flap and the nasal septal chondromucosal flap in one-stage operation. All the flaps survived completely after operation. There were no other complications excepting that two patients developed to mild lower eyelid retration after six months. Conclusion The technique consisting of the buccal rotation flap and the nasal septal chondromucosal flap is a simple and useful alternative procedure to close full-thickness defects in the lower eyelid.
ABSTRACT
Obesity is not only the high risk factor of diabetes mellitus,coronary heart disease and hypertension,but also a cause of renal damage.Diabetic nephropathy is one of the most frequent chronic microvascular complications of diabetes mellitus,and one of the leading causes of end-stage kidney failure.It is documented that the obese patients with type 2 diabetes may have obviously multiple metabolic abnormalities and are more prone to develop diabetic nephropathy.This article summarized the pathogenetic mechanisms of kidney injury in diabetic obese patients and provided some ideas in the medical therapy of diabetic nephropathy.
ABSTRACT
Objective To investigate the relationship between serum Leptin levels and insulin resistance.Methods During 2001-10~2002-08 fasting serum Leptin concentrations were measured with RIA in 196 cases(including 118 type 2 diabetes,78 controls),and height,body weight were measured to calculate body mass index(BMI).Results HbA_1c,SBP,TG,Leptin were correlated with ISI,Leptin concentration were higher in type 2 diabetes than in controls;Leptin concentration was significantly increased in obese subjects,whereas in type 2 diabetes serum Leptin concentration had no significant difference between obese subjects and non-obese subjects.Conclusion Most of obeses subjects have insulin resistance,whether obesity or not,the patients type 2 diabetes have some kind of insulin resistance.
