AIM： To evaluate the differences in the functional connectivity（FC） of the primary visual cortex（V1） between the youth comitant exotropia（CE） patients and health subjects using resting functional magnetic resonance imaging（f MRI） ***： Totally, 32 CEs（25 males and 7 females） and 32 healthy control subjects（HCs）（25 males and 7 females） were enrolled in the study and underwent the MRI scanning. Two-sample t-test was used to examine differences in FC maps between the CE patients and HCs. RESULTS： The CE patients showed significantly less FC between the left brodmann area（BA17） and left lingual gyrus/cerebellum posterior lobe, right middle occipital gyrus, left precentral gyrus/postcentral gyrus and right inferior parietal lobule/postcentral gyrus. Meanwhile, CE patients showed significantly less FC between right BA17 and right middle occipital gyrus（BA19, 37）.CONCLUSION： Our findings show that CE involves abnormal FC in primary visual cortex in many regions, which may underlie the pathologic mechanism of impaired fusion and stereoscopic vision in CEs.

This study investigated the changes in interhemispheric functional connectivity （FC） of the whole brain in open globe injury （OGI） patients, using voxel-mirrored homotopic connectivity （VMHC）, and their relationships with clinical features. Totally, 16 male and 2 female acute OGI patients and 18 sex, age, and education-matched healthy volunteers were enrolled in the study. All subjects were scanned through functional magnetic resonance imaging （fMRI）. Receiver operating characteristic （ROC） curves analyses had been used to identify the VMHC in these brain areas could be used as biomarkers to distinguish OGI and from healthy control （HC）. The mean VMHC values in multiple brain areas and clinical OGI manifestations were evaluated with a Pearson correlation analysis. OGI patients had significantly decreased VMHC in the bilateral calcarine/lingual/cuneus （BA18, 19, 30） and middle occipital gyrus （BA18, 19）. The OGI patients had abnormal interhemispheric FC in the dorsal visual pathway, which may represent the pathophysiological mechanism that underlies acute vision loss after OGI.

The spectroscopic properties and photoinduced electron transfer process have been studied in zinc phthalocyanine-viologen system with bisphenol A (ZnPcAV2+). It was found that the excited singlet state of zinc phthalocyanine moiety is quenched and the fluorescence lifetime is reduced by the linked viologen. Nanosecond laser photolysis studies showed that intramolecular quenching of the excited triplet state of zinc phthalocyanine moiety by the attached viologen occurred giving reduced viologen radical ion (V+) that survived over 50 μs.

The title compound [C16H22Br2O5] (3), was synthesized and characterized by H-1-NMR, MS and elemental analysis. Pale yellow prism crystallized from anhydrous ethanol solution was investigated by X-ray structural analysis. Crystal data: orthorhombic system space group Pbca, Mr=454.2, a=17.664(4)Angstrom b=8.625(2)Angstrom, c=24.269(5)Angstrom, z=8, Dc=1.632g/cm(3), F(000)=1776. The structure was solved by direct methods and refined to final R=0.0362, Rw=0.0357 for 1029 observed reflections with F>6.0 sigma(F).

A new type of anthracene crown ether 1, 8-anthraceno-18-crown-5 has been synthesizedand the photophysical properties upon complexation with alkali and alkaline-earth metal canonswere investigated. The fiuorescence quantum yield and lifetime are appreciably enhanced, and thestability constant Ks were determined by fluorometric titration. It was found that the magnitude ofKs is controlled by the size and charge density of the complexed canons.

AIM： To investigate the functional networks underlying the brain-activity changes of patients with high myopia using the voxel-wise degree centrality（DC） ***： In total, 38 patients with high myopia（HM）（17 males and 21 females）, whose binocular refractive diopter were-6.00 to-7.00 D, and 38 healthy controls（17 males and 21 females）, closely matched in age, sex, and education levels, participated in the study. Spontaneous brain activities were evaluated using the voxel-wise DC method. The receiver operating characteristic curve was measured to distinguish patients with HM from healthy controls. Correlation analysis was used to explore the relationship between the observed mean DC values of the different brain areas and the behavioral ***： Compared with healthy controls, HM patients had significantly decreased DC values in the right inferior frontal gyrus/insula, right middle frontal gyrus, and right supramarginal/inferior parietal lobule（P〈0.05）. In contrast, HM patients had significantly increased DC values in the right cerebellum posterior lobe, left precentral gyrus/postcentral gyrus, and right middle cingulate gyrus（P〈0.05）. However, no relationship was found between the observed mean DC values of the different brain areas and the behavioral performance（P〉0.05）.CONCLUSION： HM is associated with abnormalities in many brain regions, which may indicate the neural mechanisms of HM. The altered DC values may be used as a useful biomarker for the brain activity changes in HM patients.
