4-[4-(1H-Imidazol-4-yl)phenyl]-1H-imidazole
Qian Wang,Xiao-Li Zhao
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812032485
Abstract: In the molecule of the title compound, C12H10N4, the two imidazole substituents are related by inversion symmetry and each forms a dihedral angle of 25.02 (8)° with the benzene ring. In the crystal, molecules are linked through N—H...N hydrogen bonds, forming cyclic units [graph-set R44(28)], which generate a layered structure extending across (011).

Xiao-Li Hu
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.42043
Abstract:

An inequality describing the difference between Gamma and Gaussian distributions is derived. The asymptotic bound is much better than by existing uniform bound from Berry-Esseen inequality.

Medical Journal of Chinese People's Liberation Army , 2013,
Abstract: Objective  To construct mouse dual specificity phosphatase-1 (DUSP1) 3'-untranslated region (3'-UTR) dual luciferase reporter system, and to identify its function. Methods  The total RNA of RAW264.7 murine macrophage cells was extracted and reverse-transcribed into cDNA. The full length of mouse DUSP1 3'-UTR fragment was amplified by PCR and sub-cloned to the immediate downstream of luciferase cDNA in pGL3-control luciferase expression plasmid to obtain the recombinant plasmid pGL3-Luc-DUSP13'UTR (LuDP). LuDP was then verified by PCR, restriction endonuclease and DNA sequencing analysis. Plasmid LuDP was transiently co-transfected into NIH3T3 cells with internal control plasmid pRL-TK, and the effects of DUSP1 3'-UTR on the expression of attached luciferase gene was analyzed with dual luciferase reporter assay system 48 hours after transfection. Both the luciferase expression module from LuDP and renilla luciferase expression module from pRL-TK were co-subcloned into pLenti6-TR vector to construct dual luciferase reporter plasmid LuDP/RL. The recombinant plasmid LuDP/RL was co-transfected with pcDNA3.1-HuR-FLAG (the eukaryotic expression plasmid of binding protein HuR) and miRNA mimics mmu-miR-101a into NIH3T3 cells respectively. The effects of HuR and mmu-mi-R101a on the expression of DUSP1 3'-UTR attached luciferase gene were also analyzed with dual luciferase reporter assay system. Results  The dual luciferase reporter plasmid LuDP/RL was successfully constructed. The mouse DUSP1 mRNA 3'-UTR significantly down-regulated the expression of attached luciferase gene in NIH3T3 cells (0.14±0.01 fold, P<0.01). The co-transfected HuR up-regulated the expression of luciferase in LuDP/RL plasmid (1.40±0.20 fold, P<0.05), and co-transfected mmu-miR-101a down-regulated the expression of LuDP/RL (0.57±0.18 fold, P<0.05). Conclusion  The constructed dual luciferase reporter plasmid LuDP/RL can be used to analyze the regulatory mechanism of mouse DUSP1 gene expression controlled by post-transcriptional regulatory elements.
An Empirical Analysis of the Validity of Wagner’s Law in China A Case Study Based on Gibbs Sampler
Yan Zheng,Jiabai Li,Xiao-Li Wang,Changqing Li
International Journal of Business and Management , 2010, DOI: 10.5539/ijbm.v5n6p161
Abstract: This paper presents an empirical analysis on the relationship between the size of Chinese government, as measured by its annual spending, and the growth rate of the economy. More specifically, it is designed to examine the applicability of Wagner’s Law to the Chinese economy. The statistics used in this research are annual time series data on total government spending and gross domestic product covering the period of 1952 to 2007. Unexpectedly, our empirical results showed no strong evidence in support of the validity of the Wagner’s Law for Chinese economy. However, our research shows a characteristic of smooth time-varying parameters for the relationship between Chinese government expenditures and growth rate of GDP

The Random Storage Model under the Condition of Limited-space Storehouse
Huan WANG,Xiao-li ZHU,Hong ZHOU
Canadian Social Science , 2008,
Abstract: Aiming at the storage problem of stores, this paper set up storage model to reduce cost and improve benefit under the condition of limited-space storehouse. According to model, we calculated and obtained the ordering point where the general cost is the lowest. At the end of the paper, the model was proved by an example. Key words: storage model, optimum ordering point, expected value, Lagrange multiplier Résumé: Pour résoudre le problème de stockage des magasins dans la condition de la capacité d’emmagasinage limité, le présent article établit un modèle de stockage visant à réduire le co t et à augmenter les profits, calcule le point de commande optimale où la perte atteint le minimum, et en donne des exemples. Mots-Clés: modèle de stockage, point de commande, valeur espérée, Multiplicateur de Lagrange

Abstract: A 16-year long-term fertilization experiment was conducted on paddy soil derived from red earth to investigate the effects of different fertilization patterns on the concentrations of soil organic nitrogen (N) components. When chemical fertilizers were applied only, the soil nitrogen content was slightly infuenced. Organic fertilization, especially its combination with chemical fertilization, could significantly increase the contents of soil mineralizable N and organic nitrogen by 55.2% and 38.8%, respectively. In addition, organic fertilization could significantly improve the components of acid hydrolysable N, and lead to the increase of ammonium N (AN), amino sugar N (ASN), and hydrolysable unidentified N (HUN) by 36.5%, 68.4%, and 73.9%, respectively. When the organic fertilization was combined with chemical fertilization, soil amino acid N content was increased by 71.1%, while HUN content was decreased by 34.5%. In all fertilization treatments, the cumulative amount of soil mineralized N increased with increasing incubation time. The content of soil mineralized N under organic fertilization and its combination with chemical fertilization was higher than that under chemical fertilization.
Vasopressin and epinephrine versus epinephrine in management of patients with cardiac arrest: a meta-analysis

Abstract: Objective. A combination of vasopressin and epinephrine may be more effective than epinephrine alone in cardiopulmonary resuscitation (CPR), but evidence is lacking to make clinical recommendations. This meta-analysis compares the efficacy of vasopressin and epinephrine used together versus epinephrine alone in cardiac arrest (CA).Methods. We searched MEDLINE and EMBASE for randomized trials comparing the efficacy of vasopressin and epinephrine versus epinephrine alone in adults with cardiac arrest. The primary outcome was the return of spontaneous circulation (ROSC) and the survival rate on admission and discharge .We also analyzed ROSC in subgroups of patients presenting with different arrest rhythms, such as asystole, pulseless electrical activity (PEA), ventricular fibrillation (VF).Results. We analyzed 6 randomized trials out of 485 articles. We did not find evidence supporting the superiority of vasopressin and epinephrine used in combination, except for the survival rate at 24h 2.99 95% CI(1.43,6.28). No evidence supports the conclusion that vasopressin combined with epinephrine is better than epinephrine alone for ROSC, even amongst subgroups of patients.Conclusion. This systematic review of the efficacy of vasopressin and epinephrine use found that its combined use is better for 24h survival rate but only in one study which included 122 patients. Further investigation will be needed to support the use of this combination for cardiac arrest management.

Abstract: Nuclear matrix prepared from phaneroplasmodium of Physarum compressum was observed under TEM. The nuclear matrix with compound-fibres was obtained by use of 2mol/L NaCl + TritonX-100/NP40, while nuclear matrix with nuclear lamina was obtained by using Lis + TritonX-100/NP40. Net nuclear matrix was obtained without using RNase, showing RNA played an important role in nuclear matrix structure. The significance of dissociated nuclei of plasmodium in the study of cell biology was expounded in this paper.
