AIM: To investigate the cytotoxic effect on human corneal epithelial cells(HCECs) and the ability to faciliate corneal epithelial wound healing of carboxymethylcellulose(CMC) and hyaluronic acid(HA).METHODS: HCECs were exposed to 0.5% CMC(Refresh plus, Allergan, Irvine, California, USA) and 0.1% and 0.3%HA(Kynex , Alcon, Seoul, Korea, and Hyalein mini,Santen, Osaka, Japan) for the period of 30 min, and 4, 12,and 24 h. Methyl thiazolyl tetrazoiun(MTT)-based calorimetric assay was performed to assess the metabolic activity of cellular proliferation and lactate dehydrogenase(LDH) leakage assay to assess the cytotoxicity. apoptotic response was evaluated with flow cytometric analysis and fluorescence staining with Annexin V and propiodium iodide. Cellular morphology was evaluated by inverted phase-contrast light microscopy and electron microscopy. The wound widths were measured 24 h after confluent HCECs were scratch ***: The inhibitory effect of human corneal epithelial proliferation and cytotoxicity showed the time-dependent response but no significant effect. Apoptosis developed in flow cytometry and apoptotic cells weredemonstrated in fluorescent micrograph. The damaged HCECs were detached from the bottom of the dish and showed the well-developed vacuole formations. Both CMC and HA stimulated reepithehlialization of HCECs scratched, which were more observed in ***: CMC and HA, used in artificial tear formulation, could be utilized without any significant toxic effect on HCECs. Both significantly stimulated HCEC reepithelialization of corneal wounds.

International Journal of Ophthalmology(English edition) 2017年第6期10卷 896-901页

AIM： To investigate the effect of angiotensin II type 1 receptor blocker （ARB） and angiotensin converting enzyme inhibitor （ACEI） on intraocular growth factors and their receptors in streptozotocin-induced diabetic rats. METHODS： Forty Sprague-Dawley rats were divided into 4 groups： control, diabetes mellitus （DM）, candesartan- treated DM, and enalapril-treated DM （each group, n---10）. After the induction of DM by streptozotocin, candesartan [ARB, 5 mg/（kg · d）] and enalapril [ACEI, 10 mg/（kg · d）] were administered to rats orally for 4Wko Vascular endothelial growth factor （VEGF） and angiotensin II （Ang II） concentrations in the vitreous were measured using enzyme-linked immunosorbent assays, and VEGF receptor 2 and angiotensin II type 1 receptor （ATIR） levels were assessed at week 4 by Western blotting. RESULTS： Vitreous Ang II levels were significantly higher in the DM group and candesartan-treated DM group than in the control （P=0.04 and 0.005, respectively）. Vitreous ATIR increased significantly in DM compared to the other three groups （P〈0.007）. Candesartan-treated DM rats showed higher vitreal ATIR concentration than the enalapril-treated DM group and control （P〈0.001 and P=0.005, respectively）. No difference in vitreous Ang II and ATIR concentration was found between the enalapril- treated DM group and control. VEGF and its receptor were below the minimum detection limit in all 4 groups. CONCLUSION： Increased Ang II and ATIR in the hyperglycemic state indicate activated the intraocular renin-angiotensin system, which is inhibited more effectively by systemic ACEI than systemic ARB.

OBJECTIVE: To examine the dose-dependent impact of Asiasari Radix(A. radix) on the cell viability,differentiation and mineralization of stem cells derived from ***: Stem cells that were derived from gingiva were grown in the presence of A. radix at final concentrations that ranged from 0.001 to 10 μg/m L. The morphology of the cells was viewed under an inverted microscope and the analysis of cell proliferation was performed by using Cell Counting Kit-8(CCK-8) on day 1. The alkaline phosphatase activity test was used to assess differentiation and Alizarin red S staining was used to assess mineralization of treated ***: The control group showed spindleshaped, fibroblast-like morphology and the shapesof the cells in 0.001, 0.01, 0.1, 1 and 10 μg/mL of *** were similar to that of the control group at day 1. The cultures growing in the presence of0.001 μg/m L of A. radix at day 1 showed an increase in the CCK-8 value(P 0.05). Mineralized extracellular deposits were observed after Alizarin Red S staining and the cultures grown in the presence of 0.001 μg/m L of A. radix showed the highest value for quantitative results for bound dye(P < 0.05).CONCLUSION: Within the limits of this study, A. radix influenced the proliferation of stem cells derived from the gingiva and low concentrations of *** might enhance osteogenic differentiation of the stem cells.

AIM： To investigate the efficacy of combined topical 0.05% cyclosporine A（CsA; Restasis~？, Allergan pharmaceuticals, USA） and 0.1% sodium hyaluronate treatment in dry eyes with meibomian gland dysfunction（MGD）.METHODS： In a retrospective analysis, 53 patients（106 eyes） with MGD were enrolled and performed lid warm massage for 10 min daily and be instilled preservative free sodium hyaluronate 0.1% eye drops 4 times daily. Patients were divided into subjects treated with topical 0.05% CsA and preservative free sodium hyaluronate vehicle（experimental group, n=74 eyes） and subjects treated with the preservative free sodium hyaluronate vehicle（control group, n=32 eyes）. They were evaluated at baseline and 1, 2, and 3 mo for subjective symptoms and objective signs including tear film break-up time（t BUT）, Schirmer test, corneal staining（CS） score, lid margin telangiectasia（LMT）, meibomian gland secretion（MGS）, and conjunctival injection（CI）.RESULTS： In the short-term treatment, the experimental group showed a statistically significant improvement in the ocular surface disease index（OSDI; P〈0.001）, tBUT（P=0.004）, Schirmer test score（P=0.008） and LMT（P=0.021） by repeated measure ANOVA. Additionally, mean changes from baseline in OSDI（P〈0.001）, tBUT（P=0.001）, Schirmer test score（P=0.029）, CS score（P=0.047）, LMT（P=0.002）, CI（P=0.030） were improved better in the experimental group than in the control group at 3 mo. However, there was no significant difference between the two groups in MGS（P=0.67）.CONCLUSION： In dry eyes with MGD, 0.05% CsA improves the tear film stability as well as subjective ocular discomfort, and is effective in controlling lid margin inflammation.
