AlM: To study the effects of different concentrations of Coix seed oil on human retinal capillary endothelial cells ( HRCECs ) proliferation and vascular endothelial growth factor ( VEGF) expression in high glucose environment.
METHODS: HRCECs extracted from human fresher eyeball and cultured in vitro, and ultimately used in the experiment were the growth of 3rd ~ 4th cells, the experimental were divided into blank control group, low glucose control group, high glucose control group, high glucose + ( 50ü L/mL, 100ü L/mL, 200ü L/mL ) different concentrations Coix seed oil group. Detecting the multiplication of HRCECs by MTT, the immunocytochemical method was employed to detect the each group HRCECs of VEGF expression.
RESULTS:MTT assay results showed that: different concentrations of coix seed oil acted at HRCECs for 48h, inhibition of cell proliferation was significant difference compared with high glucose control group (P<0. 05). Within 48h showed concentration dependence. There was no statistical difference between the low glucose group and high glucose control group (P>0. 05). lmmunocytochemical assay showed that:50ü L/mL, 100ü L/mL, 200ü L/mL Coix seed oil acted at HRCECs 48h, the expression of VEGF decreased significantly compared with the high glucose control group ( P< 0. 05 ), and in a dose- dependent manner. However, in high glucose control group, the expression of VEGF was obvious higher than that of low glucose control group (P<0. 05).
CONCLUSlON:Coix seed oil can inhibit the HRCECs proliferation and suppress the VEGF expression in high glucose environment.

Aim The effect of polysaccharide of spirulina on mouse myelosuppression induced by cyclophosphamide was studied. Methods Mice in the model, treatment groups Ⅰ and Ⅱ were given cyclophosphamide(ip 100 mg · kg- 1) for there days. At the same time mice in the treatment groups Ⅰ and Ⅱ were given ig spirulin 30 mg · kg-1 and 60 mg · kg-1 for ten days, while mice in the control group and model group were given ip 20 mg · kg-1 of NS. Peripheral blood and marrow cytometry, micromcelsus and chromosome aberration were analyed. Results In the dosages of 30 and 60 mg · kg-1 polysaccharide of spirulina, the polysaccharide of spirulina had perfect action on the perihemateikon and the function of bone hematoplast induced by cyclophosphamide(P ＜0.01) and antagonistic action on increase of bone cell micronuclsus(P＜0.05); The ratio of chromosome aberration in the treated group was lower compared with that in the model group. The inhibitory ratio was 51.2% and 62.5% in the treated groups Ⅰ and Ⅱ .Conclusion Polysaccharide of spirulina can perfect the hematoplast function of mice injured by cyclophosphamide.

Objective To evaluate the relationship between damages of visual field and retinal nerve fibre layer(RNFL)thickness in primary open angle glaucoma(POAG)with high myopia.Design Retrospective,case-controlled study.Participants POAG group with high myopia(21 eyes of 17 cases),POAG group with non-high myopia(17 eyes of 16 cases),high myopia group without POAG(25 eyes of 20 cases)and normal control group(19 eyes of 17 cases).Methods The static central visual fields were tested with Humphrey 750 automated perimetry and thickness of RNFL was measured with optical coherent tomography(OCT).Main Outcome Measures Mean deviation(MD),pattern standard deviation(PSD)and mean sensitivity at upper,lower,nasal and temporal quadrants in total deviation probability plots.Thickness of RNFL at upper,lower,nasal and temporal quadrants.Results There were more obvious general depression of sensitivity in total deviation probability plots of the early POAG with high myopia than those of POAG without high myopia,and the early visual field defects of glaucoma in pattern deviation probability plots of this group.MD of POAG with high myopia was more than those of others(P＜0.05).The differences of MD,PSD and mean sensitivity between POAG with high myopia and others were significant(P＜0.05).Mean sensitivities in each quadrant of POAG without high myopia were similar to those of high myopia(P＞0.05).The thickness of RNFL of POAG with high myopia was thinner than those of others and the thickness of RNFL of normality was thicker than that of others.The correlationship between mean sensitivity and the thickness of RNFL in each quadrant was significant(P＜0.05).Conclusion Pattern deviation probability plots is an important favor for judgement of the visual field changes in POAG with high myopia.The relationship between RNFL thickness with OCT and visual field damage may provide clinically relevant information in diagnosis of POAG with high myopia

Objective To provide a practicable method for the complete display and localization of the posterolateral structures (PLS) of the normal knee through MRI study. Methods 30 tibial bone specimens were observed to establish the bony landmark for localizing the knee. In 50 cadaver knees, the angles between lateral tibial plateau and the long axis of the individual structure of PLS were measured. Then the scan methods of the oblique MR images were determined based on above results. The routine and oblique scans of T 1WI were performed in 40 normal knees. The display effect and appearance of the PLS were observed on MRI. Results The lateral tibial plateau was a stable bony landmark for measuring and localizing of the knee. In the 40 normal knees, The fibular collateral ligament could be intactly displayed on 70? posterior coronal oblique images in 34 cases (85%). The popliteus could be better seen on either 45? medial sagittal oblique in 34 cases (85%) or 60? posterior coronal oblique planes in 36 cases (90%). The popliteofibular ligament could be intactly appreciated on both 60? posterior coronal oblique in 32 cases (80%) and 70? lateral sagittal oblique images in 34 cases (85%). Although the arcuate ligament and the fabellofibular ligament could occasionally be seen on routine and oblique images, but the display rate was lower. Conclusion The oblique MR imaging can intactly display the main structures of PLS, and can be useful in diagnosing the injuries in those structures.
