Background Nomal binocular vision is achieved through accommodation and vergence.Anisometropia is associated with abnormal visual development,but its impact on accommodation and vergence is unknown.This study is helpful to make a reaonable correction plan for anisometropia.Objective This clinical study was to examine the binocular vision function in myopic anisometropia and evaluate the influence of myopic anisometropia on binocular vision function.Methods Seventy subjects with myopic anisometropia ≥ 1.0 D were recruited in Tianjin Eye Hospital and Tianjin Vocational Institute from 2006 to 2009.The subjects were assigned to the low anisometropia group with the 1.0 D ≤ spherical equivalent difference < 2.5 D and the moderate and high anisometropia group with spherical equivalent difference ≥2.5D,and other 35 individuals with spherical equivalent difference < 1.0 D were enrolled as the without anisometropia group.Binocular vision function parameters were examined in all the individuals,including comprehensive refractometer to check the diopter,Worth 4 dot to examine the binocular vision function,different distance of vertical fusional amplitudes,accommodative convergence/accommodation (AC/A) and stereoscopic vision.Written informed consent was obtained from each subject prior to the study.Results After anisometropia was completely corrected,the normal rate of Worth 4 dot examination was 94.3%,80.0% and 60.0% in the without anisometropia group,low anisometropia group,moderate and high anisometropia group,respectively,showing a statistical difference among groups (x2 =12.137,P<0.05),and the normal rate of 4 dot was less,and that of 5 dot was higher in the moderate and high anisometropia group compared with the without anisometropia group and low anisometropia group (P<0.05).No significant difference was found in the normal rate for phoria of distance among the three groups (x2 =4.489,P=0.344).The normal rate for near phoria of distance was 65.7%,42.9% and 37.1% in the without anisometropia group,low anisometropia group,moderate and high anisometropia group,respectively,with significant difference among them (x2 =6.045,P<0.05).The normal rate of stereopsis was 91.4%,77.1% and 54.3% in the without anisometropia group,low anisometropia group,moderate and high anisometropia group,respectively,which was statistically different among groups (x2 =12.863,P =0.002),and that in the moderate and high anisometropia group was significant declined in comparison with the without anisometropia group (x2 =12.208,P < 0.05).The difference of distance phoria,AC/A,negative relative accommodation (NRA),positive relative accommodation (PRA),accommodation amplitude and binocular accommodative lag were statistically different among groups (P>0.05).Conclusions The normal rate of the stereopsis,Worth 4 dot and the phoria of near distance are decreased with the increase of anisometropia,but other ocular motor parameters are normal in anisometropic subject.

Phosphate-dissolving microorganisms are widely distributed in soil, rhizosphere and other ecological environment. Understanding the characteristics of these microorganisms in solubilizing phosphates is helpful to apply them in improving P use efficiency. The obtained results indicated that the fungi had much higher capacity to dissolve the rock than the bacteria. Existence of Fe, Al, Mg and Na in the culture media reduced the rock solubilization by the bacteria, but increased the solubilization of the fungi. The higher content of the rock in the media, the lower capacity of the rock phosphate solubilization was found. The capacity was also significantly reduced if the concentration of C material in the media was higher than 3%. It was also found that the microorganisms destroyed the rock structure. The P was more easily released from the rock at further incubation. In conclusion, there is some potential to utilize the microorganisms to activate the rock phosphate.

ObjectiveTo observe the retinal function and nerve fiber layer (RNFL) thickness after laser in situ keratomileusis (LASIK). MethodsLASIK was performed in 15 cases (30 eyes) with myopia after strict preoperative examination. All examinations such as vision, correction vision, diopter, intraocular pressure, corneal thickness, ocular axis, topography scan and fundus of eye examination were performed before and 1 day, 1 week, 1 month,3 months and 6 months after operation, as well as electroretinography (ERG), visual evoked potential (VEP), optical coherece tomography at same time. ResultsThere was not significant difference in the intraocular pressure, ERG and VEP 1 day after LASIK. The thickness of RNFL decreased 1 week after LASIK (P<0.05) and recovered 1~6 months later. ConclusionLASIK does not disturb the retinal function and RNFL thickness irreversiblely.

Objective To observe the effect of rehabilitation on unilateral spatial neglect(USN) in stroke patients with hemiplegia.Methods 42 stroke patients with hemiplegia and USN accepted several kinds of rehabilitation therapies for 8 weeks.Before and after the treatment,they were assessed with 4 kinds of USN assessments,Barthel Index and National Institutes of Health Stroke Scale(NIHSS).Results After the treatments,the scores of the Barthel Index and the NIHSS had obviously improved,while the abnormal ratio emerged through the 4 kinds of USN assessments obviously decreased.Conclusion Rehabilitation can improve the activity of daily living and promote the recovery of neural function of patients with USN after stroke.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.
