Diabetic retinopathy is a major cause of blindness all over the world, and it is one of the most serious and common microvascular complications of diabetes. Breakdown of the endothelial blood - retinal barrier ( BRB ) , as occurs in diabetic retinopathy, result in vasogenic edema and neural tissue damage, causing loss of vision. The inner BRB is created by complex tight juctions of retinal capillary endothelial cells, this barrier prevents the free diffusion of substances between the circulating blood and the neural retinal, the inner BRB efficiently supplies nutrients to the retinal and removes endobiotics and xenobiotics from the retina to maintain a constant milieu in the neural retina. The central mechanism of altered inner BRB function is a change in the permeability characteristics of retinal endothelial cells caused by elevated levels of cytokines, growth factors, advanced glycation end products, inflammation, hyperglycema and loss of pericytes. This article reviews the relationship between diabetes and the ultrastructure changes of BRB.

Objective: To explore the echocardiographic cardiac geometric morphology and hemodynamics in premature infants at different gestational age with the inlfuencing factors.
Methods: A total of 150 premature infants and 150 full-term control infants were enrolled in this study. Based on gestational age, premature infants were divided into 3 groups:①(28-32+6 ) weeks,②(33-34+6 ) weeks,③(35-36+6) weeks; and full term control infants were divided into 2 groups:①’(37-38+6) weeks and②’ (39-41+6) weeks respectively. An iE33 Philips ultrasound examination was conducted to measure left ventricular end-diastolic diameter (LVEDD), LVESD, interventricular septum thickness, posterior wall thickness, left ventricular end-diastolic volume (LVEDV), LVESV, stroke volume, LVEF, left ventricular fractional shortening (LVFS), cardiac output, stroke index, cardiac index, left ventricular mass, left ventricular mass index (LVMI), left ventricular relative wall thickness, left ventricular remodeling index (LVRI) and LVEDVI.
Results: With adjusted body surface area, all parameters for cardiac geometric morphology and hemodynamics were similar among different groups,P>0.05. The day-old age (P=0.001), height (P=0.001) and body weight for low weight born infant (P=0.012), for normal weight born infant (P=0.003), for giant infant (P=0.016) were the independent inlfuencing factors for LVMI. The impact of anthropometry and the basic life indexes were similar on LVRI among groups (χ2=42.88,P=0.076), while the covariates were different on LVMI among groups (χ2=123.6,P<0.001).
Conclusion: Cardiac morphology and hemodynamics measured by echocardiography has important clinical meaning for assessing the development and maturity of neonatal hearts in premature infants.

Objective To observe curative effect of olopatadine in treatment of allergic conjunctivitis combined with frequently winking in children. Design Prospective case series. Participants Ninety seven children with frequently winking aged 3-12 years in Shanghai Eye and ENT Hospital. Methods According to the factor in causation of frequently winking (FW), 97 children were divided into allergic conjunctivitis (AC) group, trichiasis combined AC group, AC with tics group, trichiasis group, tics group and unknown cau-sation group after clinical examination. The first 3 groups with AC were treated with olopatadine 0.1% ophthalmic solution b.I.d.(n=35) and emedastine 0.05% ophthalmic solution was used q.I.d, in AC group as control(n=32). The patients were followed after 3 weeks and the extent of symptoms of FW was recorded. Main Outcome Measures Extent of the symptoms of FW. Result The effective rate of olopatadine in treating FW caused by AC or AC combined with other diseases was 80.43%. The effective rate in FW children caused mainly by AC was 82.86% which was higher than that of control drug emedastine (75.0%) (P=0.02). Seven cure cases were all in olopatadine treating group. Conclusion AC is the most common and main causative factor in FW children. Early use of olopatadine ophthalmic drop can effectively alleviate FW symptoms. (Ophthalmol CHN, 2009, 18: 272-274)
