The title complex Mn（HL）4（NCS）2（CH3CH2OH）2 has been achieved via selfassembly by incorporating manganese（Ⅱ） into pyridine-3-carbaldehyde thiosemicarbazonate ligand, and characterized by elemental analysis and single-crystal X-ray diffraction study. The crystal crystallizes in triclinic, space group PI^-, with a = 8.896（2）, b = 9.530（2）, c = 14.520（4）°A, α = 87.035（4）, β= 88.112（4）, γ= 69.434（4）°, V= 1150.9（5）°A^3, Z = 1, Mr = 984.17, Dc = 1.420 g/cm^3,μ（MoKα） = 0.612 mm^-1, F（000） = 511, the final R = 0.0574 and wR = 0.1547 for 2855 observed reflections with I〉2σ（I）. The complex contains one six-coordinated manganese ion connected by two thiosemicarbazide ligands, in which the thiosemicarbazone ligand acts as a monodentate ligand and coordinates to the center metal atoms via the pyridyl nitrogen atoms, two ethanol molecules and two isothiocyanic anions to give rise to a mononuclear structure. The coordination of a potentially tridentate thiosemicarbazone in manganese（Ⅱ） complex without using its sulfur and imine nitrogen sites is unusual. Hydrogen bonds existing in the complex link the different components to stabilize the crystal structure.

In order to test the systematics of the Amati relation, 24 long-duration GRBs with available Eγ,iso and Ep are separated into two subgroups according to the B-band luminosity of their host galaxies. The Amati relations in the two subgroups are found to be in agreement with each other within the uncertainties. Taking into account of the well established luminosity - metallicity relation of galaxies, no strong evolution of the Amati relation with the GRB＇s environmental metaUicity is implied in this study.

A dimeric chromium compound has been synthesized by hydrothermal method and characterized by IR, EPR spectra and TG-DTA technique. The title compound [Cr（aea）]2（OH）2 （aea = N-（2-aminoethyl）aspartate） crystallizes in monoclinic, space group P21/c with a = 8.9393（10）, b = 6.7198（7）, c = 14.6791（16） A, β = 91.0580（10）°, V= 881.63（17） A3, Z= 2, Mr = 486.34, De= 1.832 g/cm3, F（000） = 500,μ = 1.296 mm-1, R = 0.0271 and wR = 0.0756. Single-crystal X-ray structural analysis indicates that the title compound consists of two Cr（aea） units linked by two bridging hydroxyl groups. The geometry around each chromium center is approximately octahedral and completed by two hydroxyls and a quadridentate ligand which is formed when ethylenediamine reacts with maleic acid.

Cotton is a globally important natural fiber and oilseed crop of crucial economic significance. Molecular breeding has become a dominant method of cotton cultivation because it allows for a shorter breeding period and directional selection of high quality genes. Patent data are key resources and are the core competitiveness of agricultural development, as the world's largest and most reliable source of technical information. However, little attention has been paid to patent analysis of cotton molecular breeding. This study uses bibliometric analysis methodology and technical classification indexing to reveal global development trends of cotton molecular breeding, based on patents by retrieval methods and expert screening. The annual number of patents, the life-cycle of patent-based technology, patent portfolios of primary countries, and main patentees, as well as technical distribution of patents, were analyzed in this study. In addition, this study put emphasis on the comparative analysis of two important patentees through patent roadmaps based on the relationship among patent citations. Finally, in order to understand the trend of new molecular breeding technology, patents related to clustered regularly interspaced short palindromic repeats(CRISPR), RNA interference(RNAi), and gene chip were also analyzed, all of which apply to cotton but also to other crops. Results in this paper can provide references for cotton molecular breeding researchers and relevant management departments.

With the internationally growing popularity of traditional Chinese medicine(TCM), TCM-induced nephropathy has attracted public attention. Minimizing this toxicity is an important issue for future research. Typical nephrotoxic TCM drugs such as Aristolochic acid, Tripterygium wilfordii Hook. f, Rheum officinale Baill, and cinnabar mainly damage renal proximal tubules or cause interstitial nephritis. Transporters in renal proximal tubule are believed to be critical in the disposition of xenobiotics. In this review, we provide information on the alteration of renal transporters by nephrotoxic TCMs, which may be helpful for understanding the nephrotoxic mechanism of TCMs and reducing adverse effects. Studies have proven that when administering nephrotoxic TCMs, the expression or function of renal transporters is altered, especially organic anion transporter 1 and 3. The alteration of these transporters may enhance the accumulation of toxic drugs or the dysfunction of endogenous toxins and subsequently sensitize the kidney to ***-related drug combination and clinical biomarkers supervision to avoid the risk of future toxicity are proposed.

Objective: To investigate the effects of Ganoderma lucidum polysaccharides(GL-PS) on human fibroblasts and skin wound healing in Kunming male mice and to explore the putative molecular mechanism. Methods: Primary human skin fibroblasts were cultured. The viability of fibroblasts treated with 0, 10, 20, 40, 80, and 160 μg/mL of GL-PS, respectively were detected by 3-4,5-dimethyl-2-thiazolyl-2,5-diphenyl-2-Htetrazolium bromide(MTT). The migration ability of fibroblasts treated with 0, 10, 20, and 40 μg/mL of GL-PS were measured by transwell assay. The secretion of the C-terminal peptide of procollagen type Ⅰ(CICP) and transforming growth factor-β1(TGF-β1) in the cell supernatant was tested by enzyme-linked immunosorbent assay. The expression of β-catenin was detected by Western blot. Furthermore, the Kunming mouse model with full-layer skin resection trauma was established, and was treated with 10, 20, and 40 mg/mL of GL-PS, respectively as external use. The size of the wound was measured daily, complete healing time in each group was recorded and the percentage of wound contraction was calculated. Results: Compared with the control group, 10, 20, and 40 μg/mL of GL-PS significantly increased the viability of fibroblasts, promoted the migration ability of fibroblasts, and up-regulated the expressions of CICP and TGF-β1 in fibroblasts(P<0.05 or P<0.01). The expression of β-catenin in fibroblasts treated with 20 and 40 μg/mL of GL-PS was significantly higher than that of the control group(P<0.01). Furthermore, after external use of 10, 20, and 40 mg/mL of GL-PS, the rates of wound healing in mice were significantly higher and the wound healing time was significantly less than the control group(P<0.05 or P<0.01). Conclusion: A certain concentration of GL-PS may promote wound healing via activation of the Wnt/β-catenin signaling pathway and up-regulation of TGF-β1, which might serve as a promising source of skin wound healing.

Un-hydrogenated Diamond-like Carbon （DLC） films were prepared by pulsed laser deposition technique at different substrate temperature. The Raman spectra, the absorption and the photoluminescence spectra were measured. The dependence of structure and phetoluminescence properties on deposition temperature were studied in detail. The experimental results indicate that the sp^2 sites form small clus ters that consist of both olefinic chains and aromatic ring groups within the sp^3 matrix. With raising deposition temperature,the optical band gaps increase from 1.87 to 2.85 eV. The main band of photoluminescence centered at around 700nm shifts to short wavelength, and the intensity of this band increases. The photoluminescence can be attributed to carrier localization within an increasing sp^2 clusters. It was clarified that the DLC films are ordered with increasing deposition temperature.
