Objective To evaluate and improve the geometrical accuracy of the magnetic resonance imaging used for gamma knife radiosurgery localization. Methods Four common MRI scan programs were used in this study. The images were transferred to the Gamma Plan treatment planning system.Deviations between stereotactic coordinates based on MR images and real geometrical positions given by the construction of the phantom insert were evaluated for each study.The deviations were further investigated as a function of the spatial position of measured points in the investigated volume.Results The geometrical coordinate errors for axial and coronal images of the selected scan programs were all less than 1 mm.Optimal imaging procedure in terms of geometrical accuracy was observed using spin echo T1 and 3D FSPGR MRI sequences in the unit.Statistically significant differences were found in axial images amongSE T1,FSE T2,FRFSE Pd,FSPGR 3D sequences (F=1497.51,1873.63,2.87,3.00,P ＜0.05).The error increased along with the increase of the distance between node point and centricity.Conclusions The geometrical coordinate errors is related with the imaging program in M(il)l. Proper imaging programs and parameters should be selected according to the imageology character of patients' lesions when the radiosurgery is performed.

Objective To assess the carotid elasticity using wave intensity(WI) in subjects with different plasma glucose level.Methods 107 subjects were enrolled in this study,according to their plasma glucose levels,subjects were categorized as normal plasma glucose group (group A),normal plasma glucose in higher level group (group B) and pre-diabetes group (group C).Carotid WI examination was performed and analyzed.The parameters included magnitude of the peak during late systole (W2),negative area during the mid-ejection (NA),and stiffness parameter (β),pressure strain elasticity modulus (Ep),arterial compliance(AC),augmentation index(AI),one point pulse wave velocity(PWVβ).Results Compared to group A,W2,β,Ep,PWVβ increased significantly while AC decreased in group C(P ＜0.05),but there was no obvious difference of NA between two groups.Furthermore,this statistically difference was not found in group B(P ＞0.05).Conclusions Carotid elasticity have been altered in pre-diabetes group which can be evaluated by WI,but no marked change is observed in normal plasma glucose of higher level group.

Objective To investigate the effect of berberine on gut microbiota and T helper cell 17 (Th17), regulatory T cell (Treg) cell in sleep deprived rats.Methods SD rats were randomized into control group, model group, low-dose and high-dose group (BBR1 and BBR2, 100 mg/kg and 200 mg/kg, administrated orally).Sleep deprived rat model was established by the small-platforms-over-water method.The number of bacteria in rectum content of rat was detected.The ratio of Th17/Treg was evaluated by flow cytometry.The expression of interleukin 17 (IL-17), RAR-related orphan receptor (ROR) C, and Forkhead Box Protein P3 (Foxp3) mRNA was evaluated.Results The counting of Clostridium perfringens was elevated (P<0.05), the amount of other microbiota decreased (P<0.05), Th17/Treg ratio(P<0.05), IL-17 and RORC expression enhanced (P<0.05), Foxp3 expression decreased (P<0.05) in the gut of model rats.In contrast, treatment with berberine inhibited the proliferation of Clostridium perfringens(P<0.05), and promoted the growth of other microbiota (P<0.05), and dampened Th17/Treg ratio (P<0.05), regressed IL-17 and RORC expression, augmented Foxp3 expression.Conclusions Various doses of berberine can counteract gut microbiota imbalance and Th17/Treg imbalance induced by sleep deprivation.
