221 subjects at risk for MS were enrolled and evaluated.The discovered mean number of MS components was little greater by IDF definition than by CDS one(2.33 vs 2.09,P>0.05).The concordance rate of both definitions was 80% in diagnosing MS.The female MS prevalence was higher by IDF (18/83) than by CDS (2/83)(P<0.05).But male MS prevalence was higher by CDS (18/138) than by IDF (7/138) (P<0.05).In those with normal glycaemia, more individuals were diagnosed to have MS by IDF definition (21/94,22.3%) than by CDS one (10/97,10.3%)(P<0.05).Of people with MS diagnosed on CDS definition, 11 (12%) were non-obese.Finally, 6% MS people was missed by IDF definition due to neglecting postprandial-challenge glycemia.In conclusions, the two definitions are comparable in identifying MS and its components, while from CDS to IDF definition some MS people drift in the way as follows: from men to women, from dysglycemia to abnormal fat metabolism, and from non-obesity to obesity.

ObjectiveTo investigate the effect of hyperglycemia on calcium load and cyclic AMP content in normal and STZdiabetic rat skeletal muscle.MethodsCalcium load and cyclic AMP content were measured in vivo and in vitro after incubation with 5.6mmol/L and 16.7mmol/L glucose concentration.Atom spectrum absorption assay for calcium and radioimmunoassay for cAMP were employed.ResultsHigh concentration glucose elevated cyclic AMP content and lessened calcium load significantly.Cyclic AMP also elevated in diabetic skeletal muscle incubated with even 5.6mmol/L glucose.Diabetes was necessary for high concentration glucose to elevate cyclic AMP in vitro,because cyclic AMP did not change in normal rat muscle even incubated with 16.7mmol/L glucose.But diabetes discounted the reduction of calcium load induced by 16.7mmol/L glucose.ConclusionThe effects of hyperglycemia on calcium load and cyclic AMP content in skeletal muscle may accord with its antiinsulin action,which may be involved in the mechanism of glucose toxicity.

Objective To analyze the CT and MRI features of pituitary stalk interruption syndrome, so that to improve the diagnostic knowledge of this disease.Methods The imaging and clinical data of 4 patients with pituitary stalk interruption syndrome were retrospectively analyzed. Results In all of the 4 cases, the pituitary stalk were not shown by CT in 2 and by MRI in 4,the high signal intensity of the posterior lobe disappeared on T1WI,while a small nodule in infundibulum with high signal intensity on T1WI was found. Conclusion MRI is the most valuable imaging modality for the diagnosis of pituitary stalk interruption syndrome.

Objective To investigate the relationship of glycaemia level and the artery stiffness by means of ultrasonography. Methods Among the individuals selected for screening for impaired glucose tolerance, the systolic and diastolic diameters of both common carotid arteries in a single cardiac cycle, and the intima-media thickness were measured. Based on these measured parameters the artery compliance (AC), stiffness index and Yang's elastic Model (YEM) were calculated. Both fasting blood sugar level and that of 2 hours after 75g glucose challenge were quintiled so as to compare the arteriosclerosis surrogates. Linear correlation and partial linear regression were used to analyze the relationship of both fasting and post-challenge blood sugar levels with the three surrogates. Finally, those surrogates were also compared among different glucose tolerance categories. Normal glucose tolerance (NGT, n=97), impaired glucose tolerance (IGT, n=51) and type 2 diabetes mellitus (T2DM, n=73) were classified by the previous results of 75g oral glucose tolerance test. Results The AC decreased, and SI and YEM elevated significantly after the third quintile of fasting glycaemia, while the similar changes were found after the fourth quintile of 2 hour glycaemia. Both fasting and post-challenge glycaemia correlated inversely with AC and positively with SI and YEM. Partial correlation analysis showed that the significance of the correlation of fasting glucose with the arteriosclerosis surrogates disappeared but that of post-challenge glucose with those surrogates remained. In different categories of glucose tolerance, AC decreased but YEM rose significantly in IGT and T2DM when compared with NGT. The SI of T2DM was higher than of NGT. However the three surrogates remained similar between IGT and T2DM. Conclusions Artery stiffness was enhanced with the increase in fasting or post-challenge glycaemic levels. Post-challenge glycaemia was a better determinant than fasting glycaemia. The degree of arteriosclerosis in IGT was higher than that in NGT, but was similar to that of T2DM.
