· AIM: To investigate the efficacy and safety of intravitreal injection of plasmin, hyaluronidase, or the combination of the two in inducing posterior vitreous detachment (PVD).· METHODS: 15 mini-type pigs were assigned to three groups (Group A, B and C), 5 in each group. One eye of each pig was intravitreally injected with the studying agent,and the fellow eye was used as control. Group A received a vitreous injection of hyaluronidase 50U (0.1mL); group B received plasmin 0.5U (0.1mL); group C received plasmin 0.5U (0.05mL) combined with hyaluronidase 50U (0.05mL). The fellow eyes in each group were injected with 0.1mL balanced salt solution (BSS). All the pigs were examined with slit-lamp biomicroscope, direct and indirect ophthalmoscope, B-scan and electroretinograph (ERG). After 7 days, the animals were killed and the eyes were enucleated and examined with light microscope, transmission electron microscope and scanning electron microscope.· RESULTS: B-scan examination showed that one eye of Group A and two eyes of Group B had partial PVD at 1st day after injection and one eye of Group C at 1 hour after injection. On the 7th day, B-scan, light microscopy and scanning electron microscopy demonstrated that all the eyes of Group A and Group B had partial PVD, while none of the control eyes had PVD. Rank sum test for scanning electron microscopy results of all the groups showed P ＜0.005.Furthermore, the comparisons between every two groups were made. The results of analyses were as follows: P＞0.05 between the drug injected eyes of Group A and Group B, P＜0.05 between Group B and Group C, Group A and Group C.The b-wave and a-wave amplitudes of ERG showed no significant difference either between preinjection and postinjection in all groups or between the drug injected eyes and the control eyes in each group. Light microscopy and transmission electron microscopy revealed no damage to the retinal structure.· CONCLUSION: Intravitreal injection of hyaluronidase 50U or plasmin 0.5U or their combination can produce PVD effectively and quickly without retinal functional or structural toxicity. The combination of the two proteases was proved to be synergetic.

Objective:To study the clinical efficacy ofYiqi Huoxue Decoction in the treatment of children with spleen and kidney deficiency type nephrotic syndrome.Methods:A total of 80 children with spleen and kidney deficiency type nephrotic syndrome in our hospital from June 2014 to October 2016 were enrolled in this study.The subjects were divided into control group (n=40) and treatment group (n=40) according to the random number table method.The control group was treated with prednisone,and the treatment group was treated with prednisone combined with Yiqi Huoxue Decoction,the two groups were treated for 4 months.The clinical efficacy of the two groups were evaluate.The 24h proteinuria,total cholesterol (TC),plasma albumin (Alb),and renal function parameters including blood urea nitrogen (BUN),serum creatinine (Scr),and serum creatinine clearance (Ccr) of the two groups before and after treatment were compared.Results:The total effective rate of the treatment group was 95.00％,which was significantly higher than 67.50％ of the control group,the difference was statistically significant (P＜0.05).The 24h proteinuria,TC,BUN and Scr of the two groups after treatment were significantly lower than before treatment,the Alb,Ccr of the two groups were significantly higher than before treatment,and above indexes in treatment group were better than the control group,the differences were statistically significant (P＜0.05).Conclusion:Yiqi Huoxue Decoction have good clinical efficacy in the treatment of children with spleen and kidney deficiency type nephrotic syndrome,which can obviously improve children renal function,and is worthy of clinical application.

Objective To study the effect of intestinal trefoil factor(ITF) on nuclear factor-?B(NF-?B) in neonatal rats intestinal tissues with necrotizing enterocolitis(NEC),and to discuss whether ITF had protective function in NEC,and its role in the mechanism of NEC.Methods Fifty neonatal rats were randomly divided into 5 groups:group A as control group,group B as control plus ITF 0.2 mg group,group C as NEC group,group D as NEC plus normal saline(NS),group E as NEC plus ITF 0.2 mg.NEC models of neonatal rats were established.On the 4th day,all subjects were put to death.The intestinal tissue located at the boundary of ileum and cecum were obtained to observe histological changes and NF-?B level.Results The density of NF-?B(p65) increased significantly in group C and D compared with those in group A,B and E(Pa

AlM: To investigated the refraction and cycloplegic effects of 0. 5g/L tropicamide eye drops in various low myopia age groups, and provide clinical guidelines for proper usage of cyclopegic agent in different population.METHODS:Three low myopia age groups (n=45) were selected, non-cycloplegic and cycloplegic auto-refraction using “Shin-Nippon” auto-refractor were performed at various time point for refractive error. The subjective accommodation amplitudes were also collected at each time point.
RESULTS: The accommodation amplitude showed a similar but significant decline between 20~60min after the first cyclopegic drops in all three age groups. However, the decline of accommodation amplitudes were not statistically correlated with the results of “Shin-Nippon”auto-refraction results at different time points.
CONCLUSlON: The refraction time should be arranged according to the cycloplegic effects of tropicamide. Open-field auto-refractor could reduce the usage of cycloglegice drugs in low myopia groups, even for the youngest.

OBJECTIVETo study the effect of Ti-TiO2 nanotubes with different diameters on the adhesion of fibroblast and osteoblast, and to find which diameter was more favorable for cells' respective adhesion.

METHODSPure titanium sheets were polished and then anodized at different potentials for 1 h with Ti as anode and Pt as cathode. TiO2 nanotubes formed at 1, 5, 10 and 20 V potentials served as experimental groups and polished pure titanium served as control group. Field emission scanning electron microscopy (Fe-SEM) was used to analyze the surface topography. Stained nucleus with Hoechst33342 were used to measure the cell adhesion. The cell shape on the sample surface were analyzed with Fe-SEM.

RESULTSTiO2 nanotube array of different inner diameters from 15 nm to 100 nm were grown on titanium sheets by anodization at potentials from 1 to 20 V. At 30, 60 and 120 min, fibroblast adhesion at nanotubes anodized at 5 V was (141 ± 9), (388 ± 14) and (489 ± 15) respectively, significantly less than any other nanotube surface at the same time (P < 0.01). Nanotubes anodized at 20 V had the least inhibitory effect for fibroblast adhesion with a number of (579 ± 14) at 120 min, and the cell shape was also inhibited. At 30, 60 and 120 min, osteoblast had a significant better adhesion on nanotubes formed at 5 V than it did on any other surface at the same time (P < 0.01), except the control group at 30 min, with the adhesion number of (198 ± 10), (431 ± 10) and (501 ± 10) respectively, and osteoblast had a abundant spread on nanotubes formed at 5 V; while osteoblast adhesion on nanotubes anodized at 20 V was (152 ± 11), (403 ± 9) and (465 ± 12) respectively, less than on any other nanotube surface within the same time (P < 0.05), and the cell shape on the surface changed to be more elongate.

CONCLUSIONSFibroblast adhesion is inhabited more or less on Ti-TiO2 nanotubes of different diameters. Nanotubes formed at 5 V have the most osteoblast adhesion, and inhibit fibroblast adhesion.
