Background: Different visual acuity chart can be targeted to evaluate the visual function of patients with different eye diseases. We conducted a comparative analysis of the digital logarithm of the minimum angle of resolution (LogMAR) vision chart and the standard logarithmic vision chart for the measurement of visual acuity after retinal detachment surgery.
Methods: We used the digital LogMAR vision chart and the standard logarithmic vision chart to measure the visual acuity of 100 patients (100 eyes) who underwent retinal detachment surgery at our hospital using the LogMAR recording method and compared the differences between the mean measurements obtained by both methods for all patients and for different age groups.
Purpose: To evaluate the applicability of different visual acuity charts for outpatient pediatric visual tests.
Methods: Fifty-three children (53 eyes) aged 4-8 years undergoing visual acuity tests as outpatients were randomly selected for this study. The best corrected visual acuity (BCVA) of the eye with better visual acuity was measured for each child using the digital LogMAR visual chart, the ETDRS visual chart, and a new standard logarithm visual chart; all measurements were repeated twice and the BCVA was recorded.

Aim: To investigate the protective role of HO/CO systems in IL-1beta induced islest apoptosis and to explore the mechanisms of the protective effect of fructose-1, 6-disphosphate (FDP).
Methods: The pancreases of the rats were removed to collect islets cells. The cells were incubated with IL-1beta with/or FDP.
Objective: To investigate the influence of cervical sympathetic nerve block (SB) on blood flow volume and barrier function of intestinal mucosa after combined radiation and burn injury in rat.
Methods: SD rats were divided into three groups: control (n = 18), combined injury group (n = 100, rats with Co gamma ray body irradiation with a dose of 5 Gy plus 15% TBSA full-thickness burn injury), and combined injury with SB treatment (n = 100, with the same dose of gamma-ray irradiation and burn injury, treated with SB). Twenty rats were sacrificed on 0, 1, 5, 7 days after combined injuries for various observations.
