Fasting plasma visfatin was determined in subjects with various types of glucose tolerance. Visfatin level was (17.64±1.37)μg/L in subjects with normal glucose tolerance,and rose to (27.42±1.34) μg/L(P<0.05) in those with impaired glucose tolerance or impaired fasting glucose, and to(26.55 ± 1.64) μg/L(P< 0.05)in diabetic patients. No difference was found between obese and non-obese subjects. Positive correlation existed between visfatin and HbA1c(r=0. 317,P<0.01). Multiple linear step-wise regression showed that HbA1c and fasting plasma glucose had independent relation with the visfatin level. The result suggests that plasma visfatin may be related to glueometabolism and may play a role in the development of type 2 diabetes.

The clinical features,laboratory data,and therapeutic efficacy of two patients with thyroid hormone resistance syndrome(THRS)were reported.Two cases manifested growth retardation,raised serum TT_3,FT_3levels,and decreased~(131)I uptake.One patient presented with bird face deformity,nerve deafness,and raised TSH level.The superphysiological dosage of exogenous thyroxin inhibited the synthesis and release of thyrotropin.Thyroxin treatment proved to be effective for the patients.THRS is a disease related to thyroid hormone receptor gene mutation.The final diagnosis of this disease depends on gene analysis.
