Objective To discuss the expansion model of the eyeball and investigate the morphologic characteristics of high-my- opic eyeball through the dimensional measurement in high-myopia and emmetropia by MRI. Design Case controll study. Participants Thirty-two emmetropes (60 eyes) and 33 high myopes (60 eyes) were enrolled, without eye diseases and history of ocular surgery or in- jury. Methods 60 high-myopic eyes and 60 emmetropic eyes were measured with MRI (I.5T,PHILIPS) to get the data of three inner ocular dimensions, intraocular volume and the volume of different parts. Main Outcome Measures Three dimensions and volumes of eyeballs. Results The average value of axial (28.16?2.80 mm), horizontal (22.87+1.23 mm) and vertical length (23.40?0.99 ram) of high-myopic eyes were much bigger than those of emmetropic eyes(P=0.000), especially the axial length( with difference of 5.38 mm); The axial length was correlated with refractive error (0.36 mm/D,r~2=0.88, P=0.000). The average value of the whole ocular volume (7. 46?0.89 ml) and vitreous volume(6.90?0.8 ml) of the high myopic eyes were bigger than those of emmetropic eyes(P=0.000), while ante- rior segment volume and lens volume were about the same as that of emmetropic eyes (P=0.220, P=0.630). Conclusions The three di- mensions of high-myopic eyes were significantly longer than that of emmetropic eyes. In high myopes, the increased vitreous volume lead to the increase of the whole ocular volume. There may be two models in the ocular expansion of high myopia: global expansion and axial elongation expansion. More serious refractive error cause more obvious expansion in axial elongation.

Objective To investigate the effect ofYindanxinnaotong (YDXNT) capsule on learning and memory abilities, super oxide dismutase (SOD) activity and malondialdehyde (MDA) content in the hippocampus of rat models of vascular dementia (VD). Methods Animals were randomly divided into sham-operated group,VD vehicle group (Group VD) and YDXNT treatment group (Group VD+YDXNT); the 4-vessel occlusion was employed to establish the VD rat models in the Group VD and Group VD+YDXNT,while rats in the sham-operated group were not performed occlusion of the bilateral common carotid artery.Rats of the Group VD+YDXNT were given 1 mL liquid (9 granules of YDXNT into 360 mL normal saline) through intragastric administration 3 times daily for a consecutive 4 weeks; and rats of the other 2 groups were given the same volume of saline.The changes of learning and memory abilities were observed by Morris water maze test; the activity of SOD and the content of MDA in the hippocampus were measured. Results As compared with those in rats of the Group VD, the learning and memory abilities in rats of the Group VD+YDXNT were significantly improved (P<0.05):time in finding the platform was obviously decreased and swimming distance in finding the platform was obviously shortened in rats of Group VD+YDXNT.As compared with those in rats of the Group VD,the activity of SOD in the hippocampus was significantly increased and the content of MDA was obviously decreased in rats of the Group VD+YDXNT (P<0.05). Conclusion YDXNT could increase oxygen radical metabolism to improve the learning and memory abilities of rats with VD.

Objective To explore the relationship between X - linked spondyloepiphyseal dysplasia tarda (SEDL) gene escaping X chromosome inactivation( XCI) and SEDL phenotype. Methods RT - PCR was performed on total RNA which was isolated from blood samples of patients, female carriers and controls. Patients and female carriers were selected from the pedigree with SEDL caused by the mutation (IVS2 - 2A→C) of the gene. cDNA was analyzed by polyacrylamide gelelectrophoresis(PAGE). Results PAGE data indicateed that female carriers expressed both normal and mutant SEDL mRNA,meaning the SEDL gene escaping XCI. Family investigation showed carrier females in the SEDL pedigree presented no symptoms. Conclusions The SEDL gene escaping X chromosome in-activation is firstly identified from human body. This may explain that carrier females present no symptoms.

Objective To study the impacts of lipopolysaccharide on expressions of Cx43 and TLR4 proteins in bladder cancer cell lines and on cell proliferation and apoptosis. Methods 5637 cells were cultured in vitro. After stimulation with LPS,expressions of Cx43 and TLR4 proteins were detected by Western blot in bladder cancer 5637 cell. The proliferation and apoptosis in the 5637?control group,5637?LPS group,and 5637?LPS +cisplatin group were detected by CCK?8(cell counting kit)and flow cytometry. Results The gene expression of Cx43 in the 5637?LPS group was significantly higher than that in the 5637?control group(t=3.892,P=0.012). The expressions of TLR4 and Cx43 in 5637?LPS group were significantly higher than those in the 5637?control group(t=7.029,P=0.019;and t=18.17,P=0.003). The proliferation was significantly decreased in the 5637?control group as compared with the 5637?LPS group (t = 8.756,P = 0.018). The apoptotic rate was (8.3 ± 1.58)% in the 5637?control group and (7.8 ± 2.03)% in the 5637?LPS group,with no significant statistical difference(t = 2.935,P = 0.099). However,the rate of the 5637?cisplatin group(60 ± 4.35)%was higher than that in 5637?cisplatin + LPS group(52 ± 6.25)%,the difference was statistically significant(t = 6.992,P =0.019). Conclusions Under the stimulation of LPS,bladder tumor cells may induce tumor cells to escape immune surveillance by increasing the expressions of TLR4 and Cx43.

Background The quantitative analysis of the relationship between the vitreous volume with diopter and axial length in high myopic eye can offer a valuable basis for relevant clinical research. However, how to measure the ocular volume in vivo is a problem. Objective This study was to measure the eyeball volumes with magnetic resonance imaging ( MRI) and compare the difference of ocular volume between emmetropic and high-myopic eyes in order to explore the influent factors of changes of eyeball volumes. Methods The volumes of ocular anterior segment,lens and vitreous were measured using MRI( 1.5-T) in 60 emmetropic eyes and 60 high-myopic eyes. The ocular axial lengths of the subjects were measured by A-scan ultrasonography. The alterations of vitreous volumes with the changes of axial lengths and diopters were evaluated by linear regression analysis. Written informed consent was obtained from each patient before any medical examination. Results The mean diopters of high myopic eyes was ( - 15. 62 ± 8. 27 ) D and the mean axial lengths were ( 28. 68 ± 2. 68 ) mm, showing a significantly positive correlation between them(R2=0. 830,P = 0. 000). The mean total ocular volumes were(7.46±0. 89)ml3 and those of vitreous were ( 6. 90 ± 0. 8 ) ml3 in the high-myopic eyes with a significant increase in comparison with emmetropic eyes [ ( 6. 00 ± 0. 35 ) ml3 and ( 5. 41 ±0. 32 ) ml3 ] ( t = - 11. 846, P = 0. 000; t = - 12. 1, P = 0. 000 ). However,no significant differences were found in the anterior segment volumes and lens volumes between high myopic eyes and emmetropic eyes (t = 1. 23, P = 0. 220; t = -0. 483 , P = 0. 630 ). The vitreous volumes of high myopic eyes were significantly correlated with the diopters and the axial lengths (R2 =0. 75 ,P = 0. 000 ;R2 =0. 85 ,P = 0. 000) ,and so were the total ocular volumes (R2 = 0. 7543, P = 0. 000; R2 = 0. 8413, P = 0. 000). Conclusion The alteration of vitreous volumes is a mainly cause of difference of total ocular volume in ammetropic eyes. In high myopic eye, vitreous volume has a good linear correlation with refractive error and axial length, which may offer valuable information for vitrectomy.
