OBJECTIVE:To investigate the function change of intestinal CYP3A4 and P-glycoprotein (P-gp) under diabetic conditions and its mechanism. METHODS:Caco-2 cells were respectively added with 25, 50 and 100 μmol/L midazolam (CYP3A4 probe substrate) for incubation for 15,30,60,120,180 min;with 0.1,0.2,0.4 μg/ml rhodamine 123 (P-gp sub-strate)for incubation for 15,30,60,90,120 min to determine the substrate concentrations and incubation time. Caco-2 cells were added with insulin,glucose and fatty acid (palmitic acid and oleic acid) at different concentrations,and then the production of 1′-OH-midazolam,the metabolite of midazolam,and the intake of rhodamine 123 were determined,in order to investigated the ef-fect on the function of CYP3A4 and P-gp. RESULTS:The optimal substrate concentrations and incubation time were as follows as 50 μmol/L midazolam,0.1 μg/ml rhodamine 123 and incubation for 2 h. With the increase in the concentration of insulin,glucose and palmitic acid,the production of 1′-OH-midazolam and the activity of CYP3A4 reduced;the intake of rhodamine 123 in-creased,and the efflux transport function of P-gp decreased. Oleic acid had no significant effect on the production of 1′-OH-mid-azolam or the intake of rhodamine 123. CONCLUSIONS:Under diabetes condition,the increase of insulin,glucose and palmitic acid may reduce the function of CYP3A4 and P-gp,while oleic acid has no effect on the function.

Objective To evaluate the significance of ultrasonography in diagnosis and differentiation of morning glory syndrome. Methods Ultrasonography,CT and fundus fluorescein angiography(FFA) features were retrospectively analyzed in 6 cases of morning glory syndrome.Results Ultrasonography, CT and FFA characters of morning glory syndrome were as follow: on the B-type ultrasonogram, the dark area of vitreous cavity extended to the posterior pole and optic papilla, projecting to the basal part of muscle cones, thus the posterior part of vitreous cavity looked like a converted bottleneck. Sometimes the light ribbon of retinal detachment can also be seen. On the A-type ultrasonogram, both vitreous cavity and bottleneck showed no ultrasonic echo and acted as an equable baseline without any evident wave crest. The attachment spot of optic nerve of eye turned thin and vitreous body protruded to the posterior wall of eyeball with spherical shape on CT imaging. In the earlier period of FFA, hypofluorescence appeared on the optic disc; then ,the abnormal arteriae and vein around the optic papilla were diplayed clearly; In the later period, optic discs were dyed with fluorescein. Conclusions Ultrasonography, CT and FFA showed imageological features of morning glory syndrome from different aspects, which was helpful for differentiating similar diseases such as optic disc coloboma. Especially, ultrasonography was considered as a more safe and reliable imageological method than other imageological methods in precisely diagnosing and differentiating morning glory syndrome and superior to the traditional fundus check which gives no integrity.
