An experimental study of the protective effects of Chinese medicine compound eye-patch on asthenopia / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the therapeutic efficacy and the mechanism of Chinese medicine eye-patch with invigorating blood circulation and detoxification on asthenopia.</p><p><b>METHODS</b>A total of 180 rabbits were subjected to three tests, namely the skin microcirculation, the microvascular regeneration in the skin and the skin temperature change, with 60 rabbits for each test. The rabbits in each test were randomly and equally divided into three groups: the normal control group was treated with physiological saline on naked back once per day, the low dose group was treated with the eye-patch on naked back for 15 min once per day, while the high dose group was treated for three times per day. Forty Hartley guinea pigs were randomly and equally divided into four groups for the muscle tone test: the normal control group was treated with physiological saline on naked back, the model group was treated without any medication, the low dose group was treated with the eye-patch on naked back for 10 min once per day, while the high dose group was treated for three times per day. All treatments were continued for 14 days until the termination of the test. The microcirculatory blood flow was observed by using a video-microscopy system. The histological sections were used to detect the microvascular regeneration by observing the expression of factor VIII. The temperature changes on the skin surface were measured by using infrared thermometer, and the muscle tone was tested by the electromyography.</p><p><b>RESULTS</b>In compare with the normal or the model group, the improvement in the skin microcirculation and the blood vascular regeneration, and the decreasing in the muscle tone in low dose and high dose groups were statistically significant with confident level at P<0.05.</p><p><b>CONCLUSIONS</b>The eye-patch with invigorating blood circulation and detoxification has great enhancement in blood vascular regeneration and skin microcirculation, and great improvement in the indexes for muscle tone. The study explains certain therapeutic efficacy and mechanism of the eye-patch and shows that it could reduce the symptoms for patients with asthenopia.</p>

Screening for amblyopia among grade-1 students in primary school with uncorrected vision and stereopsis test in central China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Screening for amblyopia at earliest is important for early treatment and better prognosis. This study aimed to evaluate the validity of uncorrected distant and near visual acuity (VA) and stereoacuity for screening amblyopia in grade-1 students in primary school in central China.</p><p><b>METHODS</b>By stratified cluster sampling, 3112 grade-1 students from 11 Anyang primary schools were selected for the study. All the participants underwent uncorrected distant and near VA, stereopsis test, cycloplegic refraction, best corrected VA (BCVA), cover test, and ocular movement examination. VA was measured with a logarithm of the minimum angle of resolution (logMAR) chart. Stereoacuity was measured with the Lang II stereo card and TNO test. Amblyopia was defined as the BCVA less than or equal to 0.1 logMAR units of any eye in the absence of significant pathological abnormalities. The sensitivity, specificity, and positive and negative predictive value of uncorrected VA and stereoacuity for amblyopia were analyzed.</p><p><b>RESULTS</b>Out of the 3112 eligible students, 2893 (92.96%) completed the examinations. The average age of the students was (7.10 ± 0.41) years. Screened by distant VA with low cutoff (logMAR 0.1), high cutoff (logMAR 0.0), and near VA (logMAR 0.0), 31.64%, 73.18%, and 50.23% students were abnormal, respectively. Screened by stereopsis test, only 4.69% students were abnormal. Diagnosed by a senior pediatric ophthalmologist, 61 students had amblyopia. The sensitivities of distant VA with low/high cutoff and near VA were 92.31%, 100%, and 80.77%, respectively, whereas that of stereoacuity by TNO test was 15.38%. Simultaneous testing of either two of the three tests improved the sensitivity.</p><p><b>CONCLUSIONS</b>Distant VA test of high cutoff alone displays a high sensitivity but a low specificity. Simultaneous testing of distant VA of low cutoff and stereoacuity is a better choice to balance between sensitivity and specificity.</p>

The Associations between Visual Attention and Facial Expression Identification in Patients with Schizophrenia

OBJECTIVE: Visual search is an important attention process that precedes the information processing. Visual search also mediates the relationship between cognition function (attention) and social cognition (such as facial expression identification). However, the association between visual attention and social cognition in patients with schizophrenia remains unknown. The purposes of this study were to examine the differences in visual search performance and facial expression identification between patients with schizophrenia and normal controls, and to explore the relationship between visual search performance and facial expression identification in patients with schizophrenia. METHODS: Fourteen patients with schizophrenia (mean age=46.36+/-6.74) and 15 normal controls (mean age=40.87+/-9.33) participated this study. The visual search task, including feature search and conjunction search, and Japanese and Caucasian Facial Expression of Emotion were administered. RESULTS: Patients with schizophrenia had worse visual search performance both in feature search and conjunction search than normal controls, as well as had worse facial expression identification, especially in surprised and sadness. In addition, there were negative associations between visual search performance and facial expression identification in patients with schizophrenia, especially in surprised and sadness. However, this phenomenon was not showed in normal controls. CONCLUSION: Patients with schizophrenia who had visual search deficits had the impairment on facial expression identification. Increasing ability of visual search and facial expression identification may improve their social function and interpersonal relationship.

Meta-analysis of bifocal lenses for retarding myopia progression in school-aged myopic children / 中华实验眼科杂志

Background Whether the wearing of bifocal lenses can delay the development of myopia in school childhood is in controversy.To assess the effect of bifocal lenses using evidence-based medicine method is of important significance.Objective Present study was to compare the effect of bifocal lenses with single vision lenses in retarding myopia progression in school-aged myopic children.Methods This was a evidence-based medicine study.The systematical literature search was performed from MEDLINE(1966 to October 2010),EMBASE(1974 to October 2010),Cochrane Library,Chinese Biomedical Database(1978 to October 2010),and Chinese Clinical Trial Registry combined with hand searching of related bibliographies of journals and books were applied to collect the randomized-controlled clinical trial about bifocal lenses.Screening,evaluation and data extraction of the retrieved literature were performed by two investigators independently.Mata-analysis was used to assess the progression of refraction and axial length among included randomized clinical trials.Results Three high-quality randomized-controlled clinical trials meeting the inclusion criterion were included in this meta-analysis.The results showed that the weighted mean difference in progression of refraction was 0.22D between bifocal lenses and single vision lenses(95% CI:-0.24-0.67),and the difference was statistical insignificance(P=0.35).The weighted mean difference in progression of refraction during the follow-up durations of 6,12,18,24 and ＞30 months were 0.15(95% CI:-0.09-0.38),0.17(95% CI:-0.05-0.39),0.42(95% CI:-0.14-0.98),0.23(95% CI:-0.21-0.66) and 0.03(95% CI:-0.40-0.46),respectively without statistical significance.The weighted mean difference in elongation of axial length between two interventions was -0.17mm(95% CI:-0.26-0.08) with a statistically significance(P=0.000).Conclusion Based on currently available studies,bifocal lenses could not significantly slow the progression of myopia in myopic school-aged children in comparison with single vision lenses.Because only few high-quality studies are currently available,this conclusion need to be supported by more large-sample-size clinical trials.
