Background Congenital cataract is the major cause of blindness in children with plentiful clinical manifestations and closely linked with genetics. Objective Present study was to investigate the classification of congenital cataract in Yunnan province.Methods The manifestation characteristics of 184 eyes of 116 patients with congenital cataract in Yunnan province were analyzed.The relationship of performance of various types of congenital cataract between phenotype and hereditary feature were explored. Results All of the 116 congenital cataract eyes from 116 patients were divided into ten types based on the clinical appearance,including the complete cataract,nuclear cataract,posterior polar cataract,anterior polar cataract,coralliform cataract,coronary cataract,pulverulent cataracts,lamellar cataract and blue cataract.Bilateral nuclear cataract and unilateral entire cataract is most prevalent in these patients.Blue cataract and coralliform cataract belong to the less types.Forty-four in 116 cases were found to have the hereditary history and determined as autosomal dominant inheritance.Sporadic cases were determined in 72 cases.Conclusions The analysis of phenotype of the hereditary congenital cataract offers some clues to the classification of congenital cataract.

ObjectiveTo investigate the role of the anti-podocyte antibody in the pathogenesis of membranous nephropathy(MN).Methods Thirty-six frozen section slice from biopsies of normal kidney were randomly divided into 3 groups:A,B and C groups(n=12,respectively),then,serum of MN and IgA nephropothy patients,and normal saline were added by drops to frozen section respectively,then the changes were observed by fluorescence microscope.Twenty-one male New Zealand white rabbits were feed with standard diet for 1 week,then were randomly divided into 3 groups:D,E,F groups (n=7,respectively),and injected with the serum of MN and IgA nephropathy,and normal saline respectively through ear-border vein.24-h urinary protein, serumalbumin, serumcreatinineweredetected. Atweek8afterinjection, the histopathological changes in kidney tissue of rabbits were observed by light microscope,electron microscope and immunofluorescence staining. Results Immunofluorescenee staining displayed IgG deposition in glomerular podocytes in group A,and there was no positive expression in other two groups.The quantitative measurement of 24-h urinary protein increased significantly after injection of MN serum (P＜0.01),meanwhile the serum albumin markedly decreased (P＜0.01).The inmnunofluorescence staining showed that IgG deposited in the glomerulus capillaries wall,which presented spherical particles.Light microscope revealed the thickening of GBM without nailing process formation.Electron microscope showed the podocyte foot processes,subepithelial dense deposits.Such pathological changes were not found in E group and F group.Conclusion There is anti-podocyte antibody in blood of MN patients,which may play a role in the pathogenesis of MN.

Background Certain relationship has been found between phenotype and genes mutation of congenital cataract.It is clear that different genetic mutations can cause the same complication in congenital cataract,meanwhile,different complications may be caused by the same gene mutation.However,their mechanism is still remained unclear.Objective This study was to observe the phenotype of congenital cataract accompanied with iris dysplasia.Methods Fifteen patients with congenital cataract accompanied with iris dysplasia were included in this study.The slit lamp,gonioscope and ophthalmoscope were used for the examination of the anterior ocular segment,the anterior chamber angle and fundus on all the patients.This study was approved by the Ethic Committee of Second People' s Hospital of Yunnan Province.Written informed consent was obtained from each patient or the custodian prior to any medical procedure.Results All the patients showed binocular involvement.Congenital nuclear cataract with whole coloboma of iris was seen in 7 cases,and 2 cases showed an entire cataract associated with incomplete coloboma of iris.Entire cataract with aniridia was diagnosed in 5 patients,and suture cataract complicated with aniridia was in 1 patient.Conclusions Some regular patterns can be implied between the morphological type of cataract and iris dysplasia,which may be helpful for further study of these diseases.

AIM: To investigate the inhibition of the recombinant human endostatin adenavirus (Ad-Es) on the experimental choroidal neovascularization(CNV) models by intravitreous injection.METHODS: Experimental CNV models were induced by semiconductor laser in 30 male Brown Norway(BN) rats and randomly divided into 3 groups with 10 rats in each group.At 21d after photocoagulation, the single administration group were given intravitreous injection with Ad-Es 0.01mL;the repeated administration group were given intravitreous injection with Ad-Es 0.01mL and a repeated injection 7d later;the saline control group were given intravitreous injection with saline 0.01mL.At 7d after final administration, the leakage of fundus fluorescein angiography (FFA) was observed.Various CNV areas were measured by using laser confocal microscopy of choroidal flatmount method.Pathology and ultrastructure were observed with light microscopy, the expressions of CD105 were measured by immunohistochemistry.RESULTS: The leakage of CNV of the administration group abviously decreased as compared with those in the saline group, the leakage of repeated administration group decreased compared with that of single administration group (P<0.05).Laser confocal microscope quantitative CNV analysis showed that CNV area of the administration group was significantly smaller than that of control group, the area of repeated administration group was smaller than that of single administration group (P<0.05).Under the light microscope, the vascular endothelial cell number and quantity of the administration group were significantly lower than that of the control group, the cell number of repeated administration group was lower than that of single administration group.CD105 expression of the administration group was significantly weaker than that in the saline group;the expression of repeated administration group was weaker than that of single administration group.CONCLUSION: Ad-Es can effectively inhibit semiconductor laser induced CNV in BN rats, and the inhibition effect of repeated administration group is better than that of single administration group.It may be a useful new method in the treatment of CNV.

To investigate the advantage of using the medical sodium hyaluronate gel undergo goniosynechialysis, and to compare the difference of the viscoelastic agent and perfusion fluid by clinical control study.
●METHODS:Totally 103 cases (103 eyes) patients who had angle- closure glaucoma (ACG) with cataract all in Beijing Tongren Hospital affiliated to Capital Medical University, from September 2012 to February 2013. All the patients had primary glaucoma or recurrence ACG with cataract. Their intraocular pressure (lOP) could be controlled in normal value using one or two anti -glaucoma medications. We divided all the patients into two groups by chance. Experimental group had 53 cases (50 eyes), and control group had 50 cases (53 eyes). Two groups all had been performed phacoemulsification combined with goniosynechialysis by the same experiential operator. But experimental group did goniosynechialysis using the medical sodium hyaluronate gel, control group did goniosynechialysis using perfusion fluid. We observed the change of lOP, central anterior chamber depth and anterior chamber structure of two groups in postoperative 1mo.
●RESULTS: SPSS19. 0 statistics software was utilized to analyze the data, This study selected one- side test α =0. 05, adopted paired t - test or two- sample t - test. We obtained that experimental group lOP decreased 12. 42 ± 0. 04mmHg, anterior chamber depth increased 1. 276 ± 0. 201mm; that control group lOP decreased 6. 56 ± 0. 08mmHg, anterior chamber depth increased 0. 852 ± 0. 132mm. And experimental group anterior chamber angle opened more widely than the other group, the comparison had statistical significance (P<0. 05).
●CONCLUSlON: ln phacoemulsification combine with goniosynechialysis,use medical sodium hyaluronate gel do goniosynechialysis can more effectively decrease lOP. This because the medical sodium hyaluronate gel has high glutinousness, it can separate angle of anterior chamber and controlling lOP effectively.

Objective To explore the influence of Azithromycin on helper T lymphocyte cell(Th)1/Th2 in peripheral blood of children with bronchitic asthma.Methods Twenty-four asthmatic children and 20 healthy children were selected.Peripheral blood mononuclear cells (PBMC) were isolated from venous blood and made into cells suspension in aseptic condition.0.2 mg/L,0.1 mg/L,0.05 mg/L and 0 mg/L Azithromycin were added into the cultures in asthmatic group.The control group was not interfered with Azithromycin.The supernatant was collected after 48 h.The levels of IFN-?,IL-4 and IL-10 in the supernatant were determined by enzyme-linked immunosobent assay(ELISA).SPSS 11.5 software was used to analyze data.Results 1.The level of IL-4 produced from PBMC of asthmatic group was significantly higher than that of control group(P0.05).2.Azithromycin 0.1 mg/L more promoted the secretion of IL-4 than the other 3 concentrations(Pa0.05).3.Azithromycin 0.2 mg/L and 0.1 mg/L more increased the level of IL-10 than the control group(P0.05).Conclusions The routine drug level of Azithromycin(0.1 mg/L) had no effects on the imbalance of Th1/Th2 of asthmatic children,but could modulate the immunological function by up-regulating the level of IL-10.
