  • Roles of subretinal fluid on expression of bcl-2 oncoprotein of cultured human retinal pigment epithelial cells and fibroblast cells

    Objective To investigate the effect of subretinal fluid (SRF) with different grades of proliferative vitreoretinopathy (PVR) on bcl-2 oncoprotein expression in retinal pigment epithelium (RPE) cells and fib roblast (FB). Methods Using immunohistological staining technique and Western-blotting method to detect the expression of bcl-2 protein in RPE cells and FB under the stimulation of SRF. Results The expression levels of bcl-2 increased in both types of cells to a certain extent compared with those of the control group 4 hours after the cells subjected to SRF; 36 hours later, the expression levels of bcl-2 of experimental groups decreased more quickly than those of the control group, and the control group showed relatively higher bcl-2 protein levels at the end of observation. Conclusions SRF may stimulate the e xpression of bcl-2 in RPE cells and FB under culture at early stage, but accel arate the declining of bcl-2 protein levels a certain time after subjected to SRF.

  • Low molecular weight heparin (fraxiparne) for prevention of experiment postvitrectomy intraocular fibrin

    Purpose:To determine the efficacy of a low-molecular-weight heparin (fraxipparine) administered in the infusion fluid to prevent postoperative fibrin formation in a rabbit lensectomy and vitrectomy model. Methods:Fourteen adult pigmented rabbits were randomly as signed into two groups.Standard fragmatome lensectomies and core vitrectomies were performed prospectively in a masked fashion on control eyes with balanced salt infusion and on experimental eyes treated with fraxiparine/ml 6U in the infusate.Intraoperative bleeding was graded in a masked fashion by the surgeon. The amounts of firbrin and hemorrhage were graded in a masked fashion on postoperative days 1 through 7. Results:The mean grde of fibrin in the eyes treated with fraxiparine was lower than that in the control eyes (Plt;0.01) on postoperative days 1 through 3 respectively.Also,the average days to clear the fibrin in the eyes treated with fraxiparine was shorter than that in the control eyes (P=0.001).No statistically significant differences in the degree of intraoperative or postoperative hemorrhage were noted between the two groups. Conclusion:Low-molecular weight heparin(fraxiparine) is an effetive inhibit or of postoperative fibrin formation in a rabbit model and is not associated with is not associated with an increased risk of intraoperative or postopertive bleeding at the tested dose.

  • Quantitative analysis of biochemical components in the suprachoroidal space fluid of choriodal detachment associated with rhegmatogenous retinal detachment

    Objective To investigate the nature of the suprachoroidal fluid by detecting the concentration of total protein (TP), lactate dehydrogenase (LDH), albumin (ALB), total cholesterol (CHOL), total bilirubin (TBIL) in suprachoroidal liquid of patients who have rhegmatogenous retinal detachment with choroid detachment (RRDCD). Methods Eighteen RRDCD patients (18 eyes) who underwent vitrectomy were enrolled in this study. There were 10 males (10 eyes) and 8 females (8 eyes), 8 right eyes and 10 left eyes. There were 8 patients with age of ≤55 years, 10 patients with age of >55 years. There were 7 patients with duration of ≤30 days, 11 patients with duration of >30 days. There were 7 eyes with diopters of ≥−6.0 D, 11 eyes with diopters of <−6.0 D. There were 11 eyes with class C proliferative vitreoretinopathy (PVR), 7 eyes with class D PVR. Suprachoroidal fluid samples were collected from all the patients, and took preoperative serum samples as RRDCD group. Ten serum samples of normal people were set as control group. The concentration of TP, LDH, ALB, CHOL, TBIL in all the subjects were measured. The properties of the suprachoroidal fluid were identified by Light standard and concentration standard of ALB, CHOL, TBIL. Results There was no difference on the concentration of TP, LDH, ALB, CHOL, TBIL from suprachoroidal fluid samples in the patients with different age, sex, eyes, diopter, PVR grade (P>0.05). There was no difference on the concentration of TP, LDH, ALB, CHOL, TBIL from preoperative serum samples in the patients between RRDCD group and control group (P>0.05). There was no difference on the concentration of ALB and CHOL from suprachoroidal fluid samples and preoperative serum samples in the RRDCD patients (P>0.05), but there were significant differences on the concentration of TP, LDH, TBIL (P<0.05). According to the Light standard, there were 17 cases of exudates and 1 case of transudate. According to the concentration standard of ALB, CHOL and TBIL, there were 14, 18, and 16 cases of exudates, and 4, 0, and 2 cases of transudate, respectively. There was no difference on the identification result of Light standard and concentration standard of ALB, CHOL, TBIL (χ2=2.090, 1.029, 0.364; P>0.05). Conclusion The suprachoroidal fluid of RRDCD patients composed of TP, LDH, CHOL and TBIL. The suprachoroidal fluid is more likely to be exudate.
