[Summary] Interleukin-2 receptor antagonist (IL-2Ra,ie,basiliximab and daclizumab),a new antibody agent,is widely employed in lowering the risk of acute rejection after organ transplantation,but it meanwhile causes increasing concerns on the effect it exerts on glucose metabolism in transplant recipients,and so far the exact effect still remains controversial.New onset diabetes after transplantation (NODAT) is one of the most influential metabolic complications affecting graft survival and patients' long-term outcomes.Some of the current researches indicate that IL2Ra may improve glucose metabolism in the transplant recipients,some show just the opposite,yet others show no effects.Hence further investigations focusing this aspect are needed.

Although the type of XHD150B-IO 800mA X-ray machine possesses a damage protection electric circuit for the main thyristors, with the first switch of photographic hand valve pressed, abnormal instant exposure still appears when double (in different phase) or more than three main thyristors are broken through, short-circuited or mis-energized, and consequently the high voltage element or X-ray machine will break down. Therefore the original electric circuit must be improved. Material: A few of leads. Method: We exchange the conjunction sequence of three NO (normal open) contacting points of radiograph high voltage preparing work relay--MAG SW- R with three reverse parallel connection of main thyristors. Conclusion: The normal procedure of radiographic exposure won't be disturbed after the improvement. When whichever one or more than two main thyristors is broken through, short-circuited or mis-energized, the spoilage can be detected instantly and the protection circuit works correspondingly, which guarantees the safety of X-ray machine.

Purpose To characterize normal growth of the fetal fourth ventricle in the second trimester of pregnancy by standardized ultrasonography.Materials and Methods 516 cases of pregnant women with single fetus aged 18-27 weeks and 6 days were examined by conventional ultrasound.At the standard section of the fourth ventricle,the transverse dimension,anteroposterior dimension,circumference and area of the fourth ventricle were measured.Results The display rate of the fourth ventricles of fetuses aged 18-27 weeks and 6 days was up to 100％.There were no significant differences in the values of the fourth ventricles between fetuses with different gender (P＞0.05).The values of the fourth ventricle,including transverse dimension,anteroposterior dimension,circumference and area,increased linearly with the increase of gestational age,and there were positive correlations (r=0.374,0.378,0.387,0.379,P＜0.05).Conclusion The normal size of the fourth ventricle can be obtained by standardized measurement,which can be used as a reference for the clinical evaluation of the size of the fourth ventricle.
