ABSTRACT
Objective To evaluate the correlation of visual acuity measured using two different types of eye chart in children with amblyopia.Methods 119 cases (213 eyes) amblyopia patients were selected,including 40 cases (80 eyes) of refractive amblyopia,41 cases (58 eyes) of anisometropia amblyopia,and 38 cases (75 eyes) of strabismus amblyopia were selected.Best corrected visual acuity (BCVA) were determined using standard visual chart and visual noise dual chart and the correlation between the two visual acuity result were explored using Spearman's correlation analysis.Results The visual acuity in refractive amblyopia,anisometropia amblyopia and strabismus amblyopia determined by standard visual chart was statistically correlated with that determined by visual noise dual visual acuity chart.Conclusions The visual acuity measured by standard vision chart showed satisfactory linear relationship with that measured by visual acuity chart double among three types of amblyopia,however,the strength of correlation coefficient between different types of amblyopia were different:correlation coefficient in anisometropic amblyopia was the highest,and the coefficient in refractive amblyopia was the lowest.
ABSTRACT
Objective: To study the effects of B-lymphocyte dysfunction on the serum copper, selenium and zinc levels of rheumatoid arthritis [RA] patients, and to provide evidence for clinical practice
Methods: Sixty RA patients enrolled in our hospital from August 2009 to August 2013 were selected as the observation group
Another 60 healthy subjects who received physical examinations in our hospital were selected as the control group
Their B-lymphocyte stimulator [BlyS] levels and CD19+CD25 lymphocyte percentages were determined
The levels of trace elements were measured, and correlation analysis was performed
Results: The BlyS levels of the observation group and the control group were [0.39+/-0.21] ng/ml and [0.13+/-0.04] ng/ml respectively, which were significantly different [P < 0.05]
The percentages of CD25[+], CD19" and CD19[+]CD25] lymphocytes in the observation group were significantly higher than those in the control group [P < 0.05]
The serum copper, selenium and zinc levels of the observation group were significantly lower than those of the control group [P < 0.05]
Pearson's correlation analysis showed that the BlyS level was correlated with the levels of copper, selenium and zinc respectively [r=-0.541, -0.370, -0.430, P < 0.05]
Conclusion: Rheumatoid Arthritis may be induced by BlyS-mediated B-lymphocyte dysplasia and dysfunction, accompanied by decreased expressions of copper, selenium and zinc
ABSTRACT
Objective To investigate the compliance and its impact factors of amblyopic children treating with visual perceptual learning.Methods 116 amblyopic children treating with visual perceptual learning were investigated using self-made compliance questionnaire for amblyopic children treating with visual perceptual learning.Results The average compliance score of amblyopia in treatment of visual perceptual learning was(71.45±10.10) points,ranging from 36 to 92 points.The univariate linear regression analysis showed thatawareness of parents on the amblyopia training,communication with medical staff,parents supervise children training and eyesight improvement speed of children were the statistical significant impact factors.The further multivariate linear regression analysis showed that awareness of parents on the amblyopia training and parents supervise children training were also the statistically significant impact factors.Conclusions The compliance of amblyopic children treating with visual perceptual learning was satisfactory and its impact factors were associated with parents,the supervision and awareness of parents were the key impact factors for amblyopic children treating with visual perceptual learning.
