Randomized Controlled Trial[Preliminary study on CT retrograde intubation dacryosystography (CT-RIDC) and its impact factors].
To observe practicality and safety of CT-RIDC for the patients with presaccular lacrimal obstruction and study the related factors. To provide guidance for the diagnosis and treatment of the patients with presaccular lacrimal obstruction. ⋯ CD-RIDC may apply to pre-operative examination for the patients with the opening orifice and presaccular lacrimal obstruction.It provideed imaging evidence for diagnosis and therapy and it was safe and practical. Many factors could affect CD-RIDC. The main verified facors were the shape of the inferior orifice of nasolacrimal duct, head position of the patient and the bending angle of the tip of intubation guided needle.

[Clinical analysis of orbital exenteration for orbital retinoblastoma].
To analyze the reasons of orbital exenteration for orbital retinoblastoma (RB) patients. ⋯ The major reasons of orbital exenteration for orbital RB patients lies in the following: giving up treatment from patients, tumor recurrence in the orbit after enucleation, progressing of orbital RB after simple conservative treatment, misdiagnosis and mishandling to let RB invade into orbit rapidly.

[Protective effect of thymosin β4 against oxidative damage in cultured rabbit corneal epithelial cells].
The aim of this study was to investigate the effects of thymosin β4 (Tβ4) against oxidative damage in rabbit corneal epithelial cells in vitro. ⋯ Tβ4 has a strong protection effect against oxidative damage induced by H2O2 in corneal epithelial cells through promoting cell growth and cell migration, and the underlying mechanisms may due to the antioxidation and anti-apoptotic effects of Tβ4.

[Diabetes self-management and its association with diabetic retinopathy in patients with type 2 diabetes].
To investigate the association of diabetic self-management with the risk of diabetic retinopathy (DR) in patients with type 2 diabetes mellitus. ⋯ Higher risk of DR is associated with longer duration of diabetes,insulin therapy, higher HbA1c level, male gender, and lower level of education, whereas higher risk of DR is also associated with lower obedience to diet control and less exercise, which suggest that lower level of diabetic self-management increased the risk of DR.

[Influence of 460-480 nm wavelength light at three different irradiance on retina tissue of SD rats].
To investigate the survival of SD rat retinal cells after irradiated with 460-480 nm wavelength blue light at three different irradiance. ⋯ The safe exposure time to SD rat retina layers is 12 hours for the blue light with wavelength 460-480 nm at the irradiance 0.6 W/m(2). And the safe exposure time descends to 3 hours at the irradiance 1.5 W/m(2).
