Pediatric dry eye can occur associated with congenital,autoimmune,and inflammatory disorders.It is often misdiagnosed and untreated because of children's inability to participate in the assessment of subjective symptoms,also difficulty to be examined and unawareness of dry eye.So,it is necessary to pay more attention to dry eye in children.Etiology and characteristics of dry eye in children should be explored and understood.Multidisciplinary approaches of diagnose and treatment should be required.

Collagen crosslinking by ultraviolet A-light and riboflavin is an effective means for increasing corneal rigidity and preventing the progression of keratoconus.Visual acuity can be improved slightly.The maximum effect of the treatment locates in the anterior 300-340?m of the cornea.No statistically significant change is found for endothelial cell density.With more long-term research, prophylactic treatment of keratoconus at the early stage might become possible,preventing the development of keratoconus and additional refractive correction can be realized.

Dry eye is the most common complication after laser in situ keratomileusis(LASIK). Attention should focus on screening of dry eye before LASIK, decreasing risk factors of surgical manipulation and topical drugs effect on dry eye. Proper management before, during and after LASIK can minimize dry eye. (Ophthalmol CHN, 2006, 15:154-155 )

It is not uncommon for corneal endotheliitis in clinic.Misdiagnosis of the disease was often happened because of the insufficient knowledge on it and lacking of specific examine methods.It is the most important method for avoiding misdiagnosis of corneal endotheliitis to recognize its clinic features and detailed inquiring case history.

Objective To evaluate prognostic effects and complications of interventional embolization at different time points on patients with ruptured intracranial aneurysms of Hunt -Hess Ⅳ-Ⅴlevels.Methods Through a retrospective analysis from 2008.1 to 2012.12, we collected 162 from 200 patients who underwent interventional embolization due to ruptured intracranial aneurysms according to the criteria.Patients with serious neurological disorders , coma, and end-stage diseases were excluded.Brain CT scan was performed to identify the spontaneous subarachnoid hemorrhage of the patients , followed by CTA or digital subtraction angiography ( DSA) to ensure the accurate diagnosis of intracranial aneurysms.All of the patients at Hunt-HessⅣ-Ⅴlevels were treated with interventional embolization , and were divided into two study groups:early stage therapy group of 79 patients ( embolization at the time <72 hours after the onset) and late stage therapy group of 83 patients ( embolization at the time ≥72 hours after the onset ).Factors including pre-and post-interventional Glasgow coma score ( GCS ) and Glasgow outcome score , ( GOS) as well as barthel index ( BI ) were statistically compared between the study groups.T-test was performed to compare the data between the two study groups.Chi-square test was taken to evaluate the enumeration data.And the correlation of therapeutic time and prognosis of patients was demonstrated by binary regression analysis.Results In the patients with ruptured intracranial aneurysms at Hunt-Hess Ⅳ-Ⅴlevels, early stage intervention (63.5 ±13.5) resulted in significantly better BI after three months , and demonstrated better recovery in comparison to the late stage intervention group (34.8 ±12.7) ( t=6.127, P<0.05).But no statistical significance of post-operative GCS (6.6 ±1.6 in early therapy group;6.1 ± 1.4 in late therapy group ) and discharging GOS ( 3.0 ±0.7 in early therapy group; 2.9 ±0.7 in late therapy group) was found between the two groups (t=1.822, 0.631 respectively; P>0.05).The early therapy group also presented a significant decrease of complications , such as hydrocephalus (χ2 =6.369, P<0.05 ) and venous thrombosis (χ2 =5.158, P <0.05 ), compared to the late therapy group.Furthermore, Statistical analysis revealed that therapeutic time closely correlated with the prognosis of patients with ruptured intracranial aneurysms at Hunt-Hess Ⅳ-Ⅴ levels ( P =0.009, OR =3.897).Conclusion The early stage therapy can improve the prognosis and decrease incidence of complications , which should benefit the efficient management of the patients with interventional embolization of ruptured intracranial aneurysms.

A total of 102 cases (204 eyes) with mild ametropic amblyopia underwent refractive correction without any vision training.After wearing glasses,visual acuity was examined every 3 months during a follow-up period of 12 months.After wearing glasses 12 months,201 eyes (98.53％) were treated effectively,175 eyes (85.78％) cured basically and 3 eyes (1.47％) became invalid.The changes of visual acuity were satisfactory(P ＜0.01).The difference of visual acuity between every two observation timepoints were satisfactory(P ＜0.01).Treating mild ametropic amblyopia by refractive correction alone is both simple and effective.And it has an excellent compliance and a low cost.

The preocular tear film has recently been described as a bilaminar structure,including lipid layer and aqueous/mucin gel layer.The lipid layer has two phases,a relatively thick outer layer,containing nonpolar lipids such as wax esters,sterol esters,hydrocarbons, and triglycerides;and a thin polar inner layer,predominantly consisting of phospholipids.It s confirmed that there are differences in meibomian fatty acid composition between healthy and evaporative dry eye patients.Thus,therapies targeted at replenishing or stabilizing the lipid layer are key points to the treatment of evaporative dry eye,either as monotherapy or in conjunction with therapies designed to enhance aqueous production.

Objective To analyze the characteristics of ocular symptoms of Sjgren syndrome and to examine the relation between signs and symptoms.Design Prospective case series.Participants 36 patients with Sjgren syndrome diagnosed by rheumatisms.Methods A self-designed questionnaire was used to investigate 4 symptoms of patients including dryness,grittiness,soreness or irritation,burning or watering.A series of clinic tests were completed as follows:break-up time,fluorescein corneal staining,lissamine green conjunctival staining,Schirmer I test.The positive rate of such symptoms was calculated.The consistency of the symptoms and signs were compared.Main Outcome Measures Break-up time,fluorescein corneal staining,lissamine green conjunctival staining,Schirmer I test.Results Patients with Sjgren syndrome were marked by ocular symptoms.There were efficient statistically significant correlations between grittiness and fluorescein corneal staining,lissamine green conjunctival staining,break-up time(P

[Objective] To investigate the protective effects of different extraction of Agaricus blazei Murrill on HaCaT cells damaged by UVB. [Methods] The cell viability which was detected by MTT method was used to determine the impact of different dose of UVB and different extraction of Agaricus blazei Murrill on normal HaCaT cells and HaCaT cells damaged by UVB. [Results] ①The HaCaT cells viability declined after irradiation with UVB, and it was a dose-dependent manner. The cell viability was 53.23%when the dose of UVB was 20mj/cm2. ②The water extraction at the concentration of 0.2~4mg·mL-1, aqueous extraction at the concentration of 0.1~2mg·mL-1 and crude polysaccharide at the concentration of 0.2~1mg·mL-1 could promote the proliferation of HaCaT cells, while aqueous extraction and crude polysaccharide inhibited the proliferation of HaCaT cells at higher concentrations.③The water extraction at the concentration of 1~4mg·mL-1, aqueous extraction at the concentration of 1~2mg·mL-1 and crude polysaccharide at the concentration of 0.5~1mg·mL-1 could enhance the cells viability which was irradiated by 20mj/cm2 UVB (P<0.01). [Conclusion] The different extraction of Agaricus blazei Murrill all could relieve the photo-damage caused by UVB, and it has the potential of anti-photoaging.
