Posterior capsular opacification (PCO) is one of the major complications of modern cataract surgery.Multiple studies had demonstrated that the extracellular matrix (ECM) plays an important role in the generation and development of PCO.A variety of ECM components,including fibronectin (FN),laminin (LN),collagen,lumican,osteoponin (OPN),decorin,hyaluronic acid and vimentin,affect the biological properties of lens epithelial cells (LECs) through different mechanisms,such as regulating cell migration,adhesion and proliferation.This review focuses on the role of ECM in PCO formation in order to explore the pathogenesis of PCO and provide a potential therapeutic approach for the prevention and management of PCO.

Objective To illustrate the expressional distribution of heat shock protein 70(HSP 70) in the kidney of acute renal injury rats caused by gentamicin.Methods One hundred and fifty rats were randomly divided into 3 groups: group A (normal group), group B [80 mg/(kg?d) gentamicin to be injected], group C [160 mg/(kg?d) gentamicin to be given]. The variations of renal pathology were observed at different time phasess by light scope and electromicroscope. Simultaneously, the expression of HSP 70 in kidney was evaluated by immunohistochemistry.Results HSP 70 distributed in epithelial cells of renal tubular in acute injury rats. The expression of HSP 70 increased markedly from the 6th hour after injection, peaked at the 12th hour and lasted for 48 hours. The expression of HSP 70 in group C was higher than that in group B(P

In order to assess the feasibility of subcutaneous administration of Triptorelin with 6-week intervals for the suppression of pituitary-gonadal axis and changes of clinical signs in girls with idiopathic central precocious puberty (ICPP), 46 girls with ICPP were treated with GnRHa. Triptorelin (Decapeptyl, 3.75 mg) was administered subcutaneously (SC) at 6-weeks intervals or intramuscularly (IM) at 4-weeks intervals randomly for more than 12 months consecutively. During GnRHa therapy, clinical parameters and laboratory data, including height, weight, pubertal stage, bone age, uterine volume and ovarian size, serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and estradiol (E2), were monitored and analyzed. It was found that both treatment regimes led to regression of precocious puberty and reversal of secondary sexual characteristics. Breast developments regressed. Uterine volume was decreased after treatment, but there was no statistically significant difference. Mean ovarian volume did not change significantly during treatment. The height velocity was decreased significantly from 6.3+/-1.4 cm/year to 5.8+/-1.2 cm/year in group SC and 6.7+/-1.3 cm/year to 5.4+/-1.0 cm/year in group IM, respectively. The rate of bone maturation was reduced significantly during treatment. The ratio of deltaBA/deltaCA was 1.2+/-0.2 or 1.3+/-0.3 at the onset of therapy and decreased significantly after the treatment to 0.7+/-0.2 or 0.9+/-0.1, respectively. The predicted adult height was increased significantly and progressively during therapy. The levels of serum LH, FSH and E2 returned to the prepubertal condition. No significant side effects of therapy were noted. The most common side effect during SC treatment was that a non-irritating, 1 cm in diameter mass was palpated at the site of subcutaneous injection in the abdominal wall of patients, which disappeared after 6-12 weeks. Two girls had minimal withdrawal vaginal bleeding episodes after the first injection. It was concluded that both IM and SC triptorelin administrations were clinically effective. They induce profound suppression of hypothalamic-pituitary-gonadal axis while stabilizing height velocity, slowing bone maturation and increasing predicted adult height. These results suggest that subcutaneous injection of triptorelin in 6-weeks intervals at a dosage of 3.75 mg be a safe and acceptable regimen for ICPP

Objective To analyze the correlation of visual acuity and metamorphopsia with foveal morphology before and after vitrectomy with internal limiting membrane peeling (ILMP) in idiopathic macular epiretinal membrane (IMEM) eyes.Methods This is a retrospective case series of 47 IMEM patients (49 eyes).All the patients underwent 25G pars plana vitrectomy with IMEM removal and ILMP.The best corrected visual acuity (BCVA) was measured using the international standard visual acuity chart,and the results were converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity.The severity of metamorphopsia was measured using M-charts.The central macular thickness (CMT),inner nuclear layer thickness (INT),inner retinal layer thickness (IRT),outer retinal layer thickness (ORT),the status of ellipsoid zone (EZ) were assessed with spectral-domain optical coherence tomography at baseline and each month postoperatively.The differences in BCVA,CMT,INT,IRT,ORT and status of EZ before and after surgery were analyzed,so did the correlations between these indexes at the same time.Results Compared with baseline,the postoperative BCVA was significantly increased (F=6.133,P<0.001),but the M value,CMT,INT,IRT,ORT were significantly decreased (F=12.481,10.565,15.739,6.046,10.569;P<0.001);the integrity of EZ was improved significantly (x2=12.309,P<0.001).Preoperative BCVA was positively related to the CMT (r=0.720) and ORT (r=0.720,0.887;P<0.05),while negatively related to preoperative integrity of EZ (r=-0.295,P<0.05).The postoperative BCVA was positively related to the preoperative BCVA and postoperative CMT,ORT (r=0.774,0.754,0.842;P<0.05),while negatively related to postoperative integrity of EZ (r=-0.676,P<0.05).The preoperative M value was positively related to the preoperative CMT,INT,IRT,and ORT (r=0.931,0.668,0.840,0.637;P< 0.05).The postoperative M value was positively related to the preoperative M value and postoperative CMT,INT,IRT,and ORT (r=0.723,0.722,0.767,0.825,0.387;P<0.05).Conclusions Vitrectomy with ILMP for IMEM can improve the visual acuity,metamorphopsia and foveal morphology.Both visual acuity and metamorphopsia correlate with foveal morphology.
