By observing clinical cases, we studied the curative effect of amnion membrane transplantation on decreasing corneal neovascularization (CNV). It was a non-randomized retrospective case-control study. Among 17 cases (21 eyes) of third-degree alkali burns from 2007 to 2010, 10 cases (12 eyes) were performed with amnion membrane transplantation operation, and others were not. Amnion membrane transplantation was performed at the 3rd day after burn in the treatment group. Areas of CNV in double groups were measured at the 14th day and 60th day after burn. Area of CNV in the treatment group was (66.207±7.251)mm2 at the 14th day after burn, and was 18.27% lower than that in the control group. Area of CNV in the treatment group was (120.046±13.812)mm2 at the 60th day after burn, and was 11.35% lower than that in the control group. There was both statistical significance (Pli burn.

The single crystalline nanostructure of organic semiconductors provides a very promising class of materials for applications in modern optoelectronic devices. However, morphology control and optoelectronic property modulation of high quality single crystalline samples remain a challenge. Here, we report the morphology-controlled growth of single crystalline nanorod arrays of perylene- 3,4,9,10-tetracarboxylic dianhydride （IrFCDA）. We demonstrate that, unlike FTCDA film, PTCDA nanorods exhibits optical waveguide features, enhanced absorption, and Frenkel excitation emission in the visible region. Additionally, we measured the electrical properties of PTCDA nanorods, including the conductivity along the growth direction of the nanorod, which is roughly 0.61 S-m i （much higher than that of pure crystalline PTCDA films）.

The transport properties of La_(0.67)Sr_(0.33)Mn_(O3) (LSMO) epitaxial films on differently orientated LaAlO3 substrates have been studied. The as-deposited films with different orientation exhibit different transport behaviours. The resistivity of the films on the (100) and (110) substrates undergoes a metal--insulator transition while the resistivity of the film on the (111) substrate is insulator-like. This is attributed to the discrepancy of oxygen deficiency in the samples which is influenced by the lattice mismatch between the film and the substrate. After being annealed at 700℃ in 1-atm flowing pure oxygen for half an hour, all films have the same resistivity behaviour as the bulk LSMO, which may be important for future applications.

The binary pnictide semimetals have attracted considerable attention due to their fantastic physical properties that include topological effects, negative magnetoresistance, Weyl fermions, and large non-saturation magnetoresistance. In this paper, we have successfully grown the high-quality V_(1-δ)Sb_(2) single crystals by Sb flux method and investigated their electronic transport properties. A large positive magnetoresistance that reaches 477% under a magnetic field of 12 T at T = 1.8 K was observed. Notably, the magnetoresistance showed a cusp-like feature at the low magnetic fields and such feature weakened gradually as the temperature increased, which indicated the presence of a weak antilocalization effect(WAL). In addition, based upon the experimental and theoretical band structure calculations, V_(1-δ)Sb_(2) is a research candidate for a flat band.

Novel histone deacetylase （HDAC） inhibitors 9a-1 were designed and synthesized by coupling the carboxyl group of salicylic acid （SA） with N-hydroxycinnamamides through various alkylol amines, and their in vitro biological activities were evaluated. The N-hydroxycinnamamide/SA hybrids 9b-f and 9h showed good to moderate anti-tumor activities. Notably, compound 9e had a greater potency, comparable to vorinostat （SAHA）, in human colon carcinoma cells, which was probably, or at least partially, attributable to the positive effects of the chain length noted in allojlol amines. Furthermore, the HDAC inhibitory activities of 9e against Hela cell nuclear were also similar to that of vorinostat （SAHA）, while the tested compounds 9c-f did not exhibit any isoform selectivity in the inhibition of HDACs. In addition, compound 9e could selectively inhibit tumor cells, but not inhibit non-tumor cell proliferation in vitro. Our findings suggest that the N-hydroxycinnamamide/SA hybrids may hold significant promise as therapeutic a^ents for the intervention of human cancers.
