International Eye Science 2017;17(9):1655-1658
The corneal reconstruction is tosurgial recover the structure integrity and corneal function after suffered from various trauma, inflammation and degenerative diseases.The corneal diseases caused millions of people worldwide suffering from eyesight damages and even blindness.At present, the corneal transplant is the main therapy for corneal blindness.However, the shortage in donor corneal issue is a worldwide problem and the failure due to the immunologic rejection of host is common.Nowadays, with the development of tissue culture and bioengineering technology, the application prospect of autologous stem cell transplantation is becoming more and more popular which might replace the allogeneic transplantation, becoming an important clinical treatment of regenerative medicine.Human dental pulp stem cells (hDPSCs) is a class of adult stem cell divided from the third molar teeth.Both hDPSCs and corneal cell are from the cranial nerve in embryonic ectoderm.Extensive researches show that the hDPSCs have the potentialities in corneal cell differentiation without causing immunologic rejection of the recipient.These findings manifested the potentials of hDPSCs in the clinical applications related to ocular surface reconstruction.In this paper, the features and current investigation status of hDPSCs in ocular surface reconstruction are reviewed.
6.Expression and role of ubiqutin carboxyl-terminal hydrolase L1 in lens with age-related cataract under oxidative stress
Chinese Journal of Experimental Ophthalmology 2012;30(6):534-537
Background Oxidative damage is a major cause of age-related cataracts,and the ubiquitinproteasome system is involved in lens differentiation and development.Ubiquitin carboxy-terminal hydrolase L1 (UCHL1),one of key enzymes of ubiquitin-proteasome system,was discovered to participate in the age related diseases and oxidative stress damage. Objective This study was to investigate the effects of UCHL1 on the formation and development of age-related cataract. Methods Lens capsule were collected from 24 patients with age-related cataract(including 12 cases of cortical cataract and 12 cases of nuclear cataract) during the surgery.Five normal lens capsule membranes were obtained from eye bank of Tongji University.Human lens epithelial cells (LECs) line (SRA01/04) was also collected in this study.Expression of UCHL1 in the lens epithelial layer of different samples was assayed using immunofluorescence technology.UCHL1 eukaryotic expressing vector was constructed and transfected into cultured SRA01/04 by liposome,and green fluorescent protein (GFP) eukaryotic expressing vector was transfected at the same method as the control group.UCHL1 over-expressing cells were then exposed to different concentrations (0.2,0.3,0.4 and 0.5 mol/L) of tert-butyl hydroperoxide (TBHP) for 24 hours and subsequently monitored for cell viability evaluation by MTT assay. Results Immunofluorescence showed that UCHL1 was expressed in human lens epithelial layer,but significantly different expressing levels were seen among normal lens capsular membrane,cortical cataract and nuclear cataract ( F =13.411,P =0.000),and UCHL1 expressing levels were lower in cortical cataract and nuclear cataract than the normal lens (P =0.000,P =0.000).No significant difference was found in UCHL1 expressing level between cortical cataract and nuclear cataract ( P =0.164).Western blot analysis verified that UCHL1 exhibited a stranger expression in the UCHL1 transfected group compared with the GFP transfected group,illuminating a successful transfection of UCHL1 in SRA01/04 cells.MMT assay revealed that the A570/630 value in UCHL1 transfected cells was significantly elevated in comparison with GFP transfected cells following the treatment of 0.3 mol/L TBHP. Conclusions UCHL1 has an antioxidative ability,and it might plays an important role in the progress of age-related cataract.

Chinese Journal of Analytical Chemistry 2017;45(6):824-829
A fluorescence nanosensor based on an easily prepared fluorescent molecule, 1-oxo-1H-phenalene-2,3-dicarbonitrile (OPD), was developed for highly sensitive detection of glucose.Under the catalysis of horseradish peroxidase (HRP), 3,3′,5,5′-tetramethylbenzidine (TMB) was oxidized into oxidized TMB (oxTMB) by H2O2.And the fluorescence of OPD was quenched by the intense absorption of the formed oxTMB, thus realizing effective quantitative detection of H2O2.The linear range was 0.05-0.8 μmol/L and 1-10 μmol/L respectively, with limit of detection of 0.02 μmol/L.Besides, on the basis of transformation of glucose into H2O2 through the catalysis of glucose oxidase, this nanosensor could be further exploited for highly sensitive detection of glucose.The TMB-HRP-OPD sensor exhibited linear range of 0.1-3.0 μmol/L and 4.0-30 μmol/L respectively for detection of glucose, with limit of detection of 0.02 μmol/L.Furthermore, it was successfully applied to the determination of glucose in real human serum and the results were in good agreement with the clinical data.
