Objective To investigate the intra-splenic blood cell count of posthepatitic cirrhotic portal hypertension,and compare it with patients' peripheral blood cell count to explore the role the spleen plays in peripheral cytopenia often seen in posthepatitic cirrhotic portal hypertension.Methods A prospective study was made on 15 cases with post hepatitis B cirrhotic portal hypertension undergoing splenectomy.Intrasplenic blood was sampled from upper pole,hilus (central pole),and lower pole of the spleen respectively for blood cell count.Results were compared with that of preoperative peripheral blood.Results There were significant statistical differences in the WBC count between splenic blood and peripheral blood,(11.20 ± 4.73) × 109/L vs.(4.06 ± 1.75) × 109/L,t =5.05,P ＜ 0.05),and in PLT count,(182.45±66.57) × 109/L vs.(63.54 ±28.40) × 109/L,t =7.285,P ＜0.05.There was no differences in the RBC count,(3.55 ± 0.94) × 1012/L vs.(3.01 ± 0.62) × 1012/L,t =1.874,P ＞ 0.05.Positive correlations were found between splenic PLT count and peripheral PLT count (r =0.610,P ＜0.05).Conclusions In posthepatitic B cirrhotic portal hypertension patients the intra-megalosplenic PLT and WBC count are significantly higher than that in peripheral blood.Megalosplenic PLT count correlates positively with peripheral PLT count.

Objective To find the correlation between real best corrected visual acuity (BCVA) and test-ing results of microperimetry and visual evoked potential (VEP) and to explore a newmethod in record-ing BCVAin macular disease. Methods Sixty-two patients with macular disease (macular disease group, 62 eyes) and eighteen healthy volunteers (control group, 36 eyes) had BCVA, microperimetry and VEP recorded. Results (1) By microperimetry, the values of retinal mean sensitivity and fixation percentage in macular disease group were lower than that in control group. The bicurve ellipse area in macular dis-ease group was higher than that in control group. By V EP, P100 amplitude under 0.5 cpd and 2 cpd in macular disease group were significantly higher than that in control group and the latency was prolonged (P<0.05). (2) In macular disease group, BCVAhad significant positive correlation with retinal mean sen-sitivity, bicurve ellipse area, macular central 2°and 4°fixation percentage, respectively (P<0.05). There was a significant correlation between retinal mean sensitivity and P100 amplitude (P<0.05). (3) multiple linear regression equation was y=0.053 x1+0.008 x3+3.897 (y was BCVA, while x1 was retinal mean sensi-tivity and x3 was P100 amplitude under 2 cpd). Conclusion C ombined use of microperimetry and VEP is useful in the assessment of BCVAin macular disease.

Objective:To investigate the application valve of bFGF to improve the viability of subdermal vascular network flap.Methods:Four white healthy pigs were used,each pig had 6 SVNF on back,16cm?4cm,totally 24 flaps were divided randomly into 2 groups:The bFGF groups and the control groups.On postoperative day 6,we observed the appearance of the flaps.The survival area of each flap was measured and the flap was harvested for histological analysis and the density of angiogenesis was also examined.Results:On postoperative day 6,the survival rates of the bFGF group and the control group were (81.2?1.7)% and (66.2?1.8)% respectively,the angiogenesis density of the middle and the distal segment in the bFGF group was (16.7?6.0)/mm2,(29.7?5.5)/mm2,(14.9?6.0)/mm2 respectively,while (16.6?4.0)/mm2,(21.4?5.2)/mm2,(3.5?5.1)/mm2 respectively in the control group.The bFGF group was superior to the control group in the appearance and histological analysis of the flaps.Conclusion:The results suggest that the injection of bFGF locally can promote the survival rate by accelerating the blood circulation of the SVNF’ bottom and edge,shorten the division time of SVNF and broaden the ratio of length and width.

Objective To compare the correlation between contrast vision (CV) and sweep visual evoked potential acuity (SVEP-A) among people with emmetropia, mild myopia, and moderate myopia. Meth-ods The CV and SVEP-A were tested individually in 96 eyes from healthy young volunteers, including 37 eyes of emmetropia, 27 eyes of mild myopia, and 32 eyes of moderate myopia. The statistic analysis was done by ANOVA analysis and rank sum test. Results (1) With the decrease of contrast, CV and SVEP-A decreased in every group. (2) At 100% contrast, the difference of CV between emmetropia and mild myopia had statistical significance (P<0.05). At 100%, 25% and 10% contrast, the difference of CV between emmetropia and moderate myopia had statistical significance (P<0.05). (3) In the same group, the difference of 100% and 25% contrast had statistical significance (P<0.05). So was between 100% and 10% contrast. (4) At 100% and 10% contrast, the difference of CV and SVEP-A had statis-tical significance (P<0.05). Conclusion The CV of myopia relates to many factors including ametropia and fundus lesions. The correction of ametropia is important to the values of CV and SVEP-A.
