Objective To explore the effects of ultraviolet irradiation on platelet. Methods Three assays were been developed.These include platelet count,release of alpha granule membrane protein 140(GMP-140)and morphology of platelet by electron micrograph in those samples before and after ultraviolet irradiation.Results Compared with the nonirradiated controls,the irradiated units showed significant changes including decrease of platelet count,increase of release of GMP-140 and platelet lesion in morphology.Conclusion Ultraviolet irradiation may have activation and lesion effect in platelet.

Objective To evaluate the X-ray diagnosis value of intestinal malrotation in adults.Methods The X-ray findings of 16 cases with intestinal malrotation confirmed by surgery were analyzed retrospectively. All of them were taken X-ray plain films, 11 cases were taken alimentary tract barium meal,and 5 cases were taken barium enema. Results Eight cases were found incomplete obstruction of the duodenum, and 2 cases were found low small intestine obstruction on the X-ray plain films. The alimentary tract barium meal showed 4 cases with dilatation and incomplete obstruction of the duodenal bulb to horizontal segment,and the distal end of narrowing intestine appeared as a rat tail,7 cases showed the abnormal duodenal location and shape,called "strip" sign. Four cases were found abnormal duodenojejunal flexure by barium enema examination. Conclusion The alimentary tract barium meal and barium enema examination has great diagnosis value for intestinal malrotation in adults.

Objective To explore the influence of gender and age on auditory startle reflex in healthy adults.Methods A total of 150 healthy volunteers (92 males and 58 females) aged from 18 to 60 years were recruited for this study.A modified startle reflex paradigm was adopted.Furthermore,gender-age differences on startle magnitude,habituation,perceived spatial co-location induced prepulse inhibition (PSC-PPI) and perceived spatial separation-induced prepulse inhibition (PSS-PPI) in healthy volunteers were analyzed.Results ① There was no significant difference in amplitude and habituation of startie reflex between males and females (F=0.29,P=0.593;F=1.57,P=0.212).PSC-PPI and PSS-PPI were significantly higher in males (PSC-PPI:(34.68± 20.81) %,PSS-PPI:(44.56 ± 23.19) %) than those in females (PSC-PPI:(23.11±22.43)%,PSS-PPI:(35.21±25.09)%) (F=9.48,P=0.002;F=4.76,P=0.031).② There was a negative correlation between startle magnitude and age (r=-0.29,P<0.01),however,no obvious correlations between age and PSC-PPI or PSS-PPI as well as habituation were observed.③Bivariate analysis of variance showed that no interaction between gender and age was found to the indexes of startle reflex(F=0.71-1.36,all P>0.05).Conclusions There are differences for gender and age in the indexes of startle reflex.In detail,age chiefly influences startle magnitude,while gender mainly affects the prepulse inhibition.
