AIM: To evaluate the outcome after surgery for unilateral superior oblique(SO) palsy in ***: The medical records of 39 patients that underwent surgery for unilateral SO palsy between January 2003 and December 2012 at Caritas Medical Centre, Hong Kong, were retrospectively reviewed. All surgeries were performed by a single surgeon. Pre-operative assessments for vertical deviation, cyclo-deviation, and Knapp’s classification were obtained to determine the nature and degree of surgical *** deviation was measured at 1wk; 1, 6mo and on last follow-up day post-operatively. Cyclo-deviation was measured on last follow-up day ***: During the 10 y period, 39 subjects were recruited. The most common etiology was congenital(94.9%). Knapp’s Type III(66.7%) and Type I(12.8%)classifications were the most common subtypes. To treat SO palsy, the most common surgical procedures were:isolated inferior oblique(IO) anteriorization(41.0%),isolated IO myectomy(10.3%), and isolated IO recession(10.3%). At 3.5 ±2.1y post-operatively, the vertical deviation was significantly reduced(15.1 ±6.2 PD versus0.5±1.4 PD, P without significant improvement in cyclo-deviation(P =0.5). Initial vertical deviation was correlated with cyclo-torsion(r =0.4, P =0.007). Those with over-correction had greater initial vertical deviation(19.4±7.2 PD versus 13.2±4.3 PD, P =0.003). After a single operation, 84.6% of subjects achieved a vertical deviation within ±3 PD.· CONCLUSION: The majority of subjects achieved corrected vertical deviation after a single surgery although there was no improvement in *** with over-correction of primary position deviation had greater preoperative vertical deviation and it may be related to simultaneous multiple muscle surgery.

Single crystals of two liquid crystal compounds, 5-{[4＇-（（（pentyl）oxy）-4-biphenylyl）carbonyl]oxy}-1-pentyne （A3EO5） and 5-{[（4＇-nonyloxy-4-biphenylyl）carbonyl]oxy}-1-pentyne （A3EO9）, have been prepared by solution growth technique. The morphologies and structures of A3EO5 and A3EO9 crystals were investigated by wide angle X-ray diffraction （wXRD）, atom force microscope （AFM） and transmission electron microscope （TEM）. In contrast to the same series of compounds which have a longer alkyl tail, 5-{[（4＇-heptoxy-4-biphenylyl）carbonyl]oxy}-1-pentyne （A3EO7）, 5-{[（4＇-heptoxy-4-biphenylyl）oxy]carbonyl}-1-pentyne （A3E＇O7） and A3EO9, A3EO5 shows strikingly different crystalline behavior. The former three compounds have only one crystal form, whereas A3EO5 exhibits polymorphism. Specifically, A3EO5 crystals grown from toluene solution show two crys- tal forms. The first one is crystal I which adopts a monoclinic P112/m space group with unit cell parameters of a= 5.79A, b=8.34A, c=43.92/k, y=96°, and the other one is crystal II which adopts a monoclinic P112 space group with unit cell parameters of a=5.55A, b=7.38A, c=31.75 ]k, y=94°. when using dioxane as the solvent to grow A3EO5 crystal, we can selectively obtain crystal Ⅰ. A3EO5 melt-grown crystals also have two crystal forms which derive from crystal I and crystal Ⅱ, respectively. The different crystalline behavior of the compounds should correlate with their different electron dipole moment resulting from the different length of alkyl tail.

Organic and inorganic clusteroluminescence have attracted great attention while the underlying mechanisms is still not well ***,we employed a series of ancient inorganic complexes platinocyanides with aggregation-induced emission property to elucidate the mechanism of clusteroluminescence including how does the chromophore form and how does the solid structures influence the luminescence *** results indicate that the isolated platinocyanide cannot work as a chromophore to emit visible light,while their clusterization at aggregate state can trigger the d-orbitals coupling of the platinum atoms to facilitate the electron exchange and delocalization to form a new chromophore to emit visible ***,the counter ions and H2O ligands help to rigidify the three-dimensional network structure of the platinocyanides to suppress the excited state nonradiative decay,resulting in the high quantum yield of up to 96%.This work fundamentally helps understanding both the organic and inorganic clusteroluminescence phenomenon.

作者： LAM jacky wing yip FAISAL Mahtab NG Ka Ming LUO Kathy Qian Department of Chemistry The Hong Kong University of Science & Technology (HKUST) Clear Water Bay Department of Chemical and Biomolecular Engineering HKUST Clear Water Bay Bioengineering Graduate Program HKUST Clear Water Bay

A fluorogen named 1-decyl-1-methyl-2,5-bis{4-[(N,N-diethylamino)methyl]phenyl}-3,4-diphenylsilole (3) was synthesized. It emitted weakly as isolated molecule but strongly as supramolecular aggregate, showing a characteristic behavior of aggregation-induced emission (AIE). The molecules of 3 formed highly emissive nanoparticles in aqueous media, which quickly and selectively marked cytoplasm of HeLa cells and posed no toxicity to the living cells. The fluorogen is thus a promising candidate mate-rial for cell imaging as a sensitive, selective and cytocompatible biosensor.
