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.

An organic-inorganic mercury coordination compound [Hg（DMSO）2（H2O）]2 [GeW12O40]· DMSO·H2O （DMSO =dimethyl sulfoxide） has been synthesized and characterized by IR, UV spectra, elemental analysis, TG-DTA and X-ray single-crystal diffraction. Structural analysis revealed that in the title compound, the mercury is three-coordinated to show the distorted trigonal cone geometry, and depending on the electrostatic interaction to connect the polyanion [α-GeW12O40]^4-. TG-DTA study manifests the decomposition temperature of the polyanion framework in the title compound is 513.5℃, which is much higher than that of the anion framework. It means that the formation of the organic-inorganic mercury coordination compound made the polyanion [α-GeW12O40]^4- to he more stable.

Sparfloxacin can be oxidized by nitrous acid, then react with hydroiodic acid to form a fluorescent derivative. Based on this, a reversed-phase high performance liquid chromatographic pre-column derivatization new method is described for the determination of sparfloxacin in human urine. The linear range is 0.05 mg/L to 4.0 mg/L, the recoveries are 91.5%similar to 95.7% and the RSD is 1.2%similar to4.2%. The results showed that this method is suitable for the determination of sparfloxacin in human urine.

Background Argon laser peripheral iridoplasty （ALPI） is proved to be effective in lowering intraocular pressure （lOP） of patients with mild acute primary angle closure （APAC）. It is unclear whether this laser treatment is equally efficient in managing patients with severe APAC. This study aimed peripheral iridotomy （LPI） on patients with refractory APAC, therapy. to evaluate the IOP-lowering efficacy of ALPI and laser who have previously responded poorly to intensive medical Methods Thirty-six patients （8 men and 28 women） were identified as medically refractory APAC, who still had ocular pain, red eye, hazy cornea, closed anterior chamber （AC） angle, and lOP of not less than 21 mmHg after two days or more of anti-glaucoma medication. All enrolled patients underwent ophthalmologic examinations including measurement of visual acuity （VA）, best corrected VA （BCVA）, lOP, biomicroscopy, and gonioscopy followed by ALPI immediately in the APAC eye and LPI in both eyes. Results All patients were affected unilaterally, with average age of （54.6±11.7）（range, 37.0-75.0） years old. The mean lOP value of the affected eyes dropped from （31.6±7.7）（range, 21.0-39.0） mmHg at enrollment to （18.4±8.7）（range, 10.0-27.0） mmHg 2 hours after ALPI. At follow-up day 7, the mean lOP value maintained at （14.8±4.2）（range, 9.0-21.0） mmHg, which was significantly different （P=0.000） compared with baseline. The average decrease of lOP in the APAC eyes was （16.8±7.4）（range, 12.0-21.0） mmHg. At follow-up three years later, the mean lOP of the APAC eyes stabilized at （16.3±3.2）（range, 9.0-20.0） mmHg with at least 180° of AC angle opened. Conclusion ALPI and LPI lower the lOP of medically refractory cases of APAC though they have responded poorly to anti-glaucoma medication.

中国的政治协商制度承担着协商民主的功能,是人民代表大会票选式民主的补充。政协由34个不同的界别组成,教育界别属于其中之一。政协委员一项重要的工作形式即是提案。通过对近几届教育界别政协委员组成结构及教育提案进行统计显示,教育界别政协委员的组成结构比较单一,界别的组织化程度低、委员提案的界别属性也不强,未能很好地实现界别设置的目的。应该通过调整界别设置,提高界别组织化程度与提案的界别属性,以及加强政协工作的程序法治等几个方面来改善。
