黃偉(Huang Wei),彭靜(Peng Jing) 중국어문학연구회 2021 중국어문학논집 Vol.- No.129

In the development map of Chinese classical Ci-poetry, Ci-poetry in the Qing Dynasty occupies an important position. Chen Wei-song played an important role in promoting the development of Ci-poetry in the Qing Dynasty. First of all, Chen Wei-song broke through the concept of “The poem is solemn and Ci-poetry is charming”and “ to amuse the guests and relax one"s mind”and put forward the great idea of “choosing words is to preserve words, that is, to preserve history.”.He elevated the Ci-poetry which is considered as “Xiao Dao”and “Shi Yu” by traditional scholars to a literary position of equal importance with the classics and history. Chen Wei-song"s admiration of Ci-poetry greatly promoted the continuous movement of Ci-poetry in Qing Dynasty. Secondly, Chen Wei-song invoked the poetic viewpoint of “An injustice makes an outcry”and “Poverty makes progress”.On the basis of respecting the style of writing, Chen Wei-song further emphasized the use of words to express the difficulties of times. Thirdly, Chen Wei-song"s aesthetic orientation was based on his proposition that he was not partial to one school in terms of aesthetic style. Finally, Chen Wei-song"s boldness and harshness of Ci-poetry lead to the evolution of the style of Ci-poetry in the early Qing Dynasty. Chen Wei-song has opened up a new frontier in the pioneering of Ci-poetry.

Objective: The aim of this study was to evaluate the effects of three feeding systems, i.e., indoor feeding (CON), indoor feeding with 4-h daily access to grazing artificial pasture (ITGP), and indoor feeding with 8-h daily access to grazing artificial pasture (IEGP), on the plasma antioxidant and immunological capacity, slaughter characteristics, meat quality and economic efficiency of Huang-huai lambs. Methods: Thirty-three healthy Huang-huai rams with similar body weight (approximately 5 mo of age, 28.96±1.01 kg) were assigned equally to three experimental groups. When finished fattening, six lambs from each group were collect blood samples for plasma analyses and then slaughtered to determine slaughter characteristics and obtain biceps brachii muscle for further analysis of meat quality and fatty acid profile. Results: Compared to CON group, animals submitted to ITGP and IEGP groups resulted in greater contents of serum glutathione peroxidase, immunoglobulins (IgA, IgG, and IgM), polyunsaturated fatty acids (PUFA), n-6 PUFA, and PUFA/saturated fatty acid (FA) ratio and lower palmitic /oleic acid ratio (p<0.05). Moreover, animals in ITGP group exhibited a higher (p<0.05) loin eye area, content of meat crude protein (CP), and eicosetrienoic acid compared to CON group, while slaughter performance was superior (p<0.05) to that of the IEGP group. The economic efficiency of ITGP group was 70.12% higher than that of CON group, while the IEGP group exhibited a decrease of 92.54% in economic efficiency compared to the CON group. Conclusion: Restricted grazing time combined with indoor feeding was more effective in conferring superior body health, carcass traits and economic efficiency in Huang-huai lambs, as well as higher CP content and healthier FA composition in the resulting meat.

Carbon disulfide (CS2), a common organic solvent, induces a variety of adverse effects in the male reproductive system. In this study, we investigated the cytotoxicity, ultrastructural changes, and potential apoptotic induction mechanisms of CS2 in mixed cultures of Sertoli and germ cells. Sertoli and germ cells were cocultured and treated with CS2 for 24 h. Growth rates were noted, and apoptotic cells were identified by Hoechst 33258 staining. Ultrastructure changes were observed via transmission electron microscopy (TEM). Mitochondrial membrane potential and expressions of apoptosis-related factors (cytochrome c, Bax, Bcl- 2, caspase-3 and caspase-9) were examined by JC-1 staining, western blot, and real-time PCR. The results showed that CS2 treatment was associated with reduced growth rates of Sertoli-germ cells. Ultrastructure changes in Sertoli-germ cells treated with CS2 were typical of apoptosis. In addition, CS2 treatment depolarized mitochondrial membrane potential, upregulated Bax levels and downregulated Bcl-2 levels, released cytochrome c from the mitochondrial intermembrane space to the cytosol, and triggered mitochondria-mediated apoptosis. Subsequently, caspase-9 and caspase-3 were activated, resulting in Sertoli-germ cells apoptosis. The above data suggest that CS2 has adverse effect on the viability of Sertoli-germ cells and induces apoptosis through mitochondrial pathway.

Objective In this research, the influence of breviscapine on anxiety, fear elimination, and aggression and the potential mechanism was investigated. Methods Anxiety and locomotion were analyzed by elevated plus maze and open field test in mice. Bussey-Saksida Mouse Touch Screen Chambers were used to perform fear conditioning. Territorial aggression was assessed by resident intruder test. Protein levels were evaluated by Western blot. Breviscapine improved fear-extinction learning in BALB/cJ mice. Results Breviscapine at 20-100 mg/kg increased center cross number, total distance traveled, and velocity in a dose-dependent manner. On the other hand, breviscapine at 20-100 mg/kg decreased the immobility time in open field test. In addition, breviscapine at 20-100 mg/kg increased the ratio of time on the open arm, time on the distal parts of the open arm, and total distance traveled in elevated plus maze. Breviscapine at 100 mg/kg increased the average attack latency and decreased the number of attacks over the last 3 days of resident intruder test. In hippocampus, protein levels of postsynaptic density protein-95 and synaptophysin were elevated by breviscapine at these three doses. Conclusion The administration of breviscapine alleviates fear extinction, anxiety, and aggression, while increases locomotor in a dose-dependent manner, which might be associated with its influence on synaptic function.

Investigation of surface-piercing fixed structures with different shapes for Bragg reflection of water waves

Wei-Wei Ding,Zao-jian Zou,Jing-Ping Wu,Bai-Gang Huang 대한조선학회 2019 International Journal of Naval Architecture and Oc Vol.11 No.2

Bragg reflection of water waves by three kinds of surface-piercing fixed structures with rectangular, cosinoidal and triangular shapes is studied. Boundary element method is used to analyze the wave scattering by these structures based on the linear wave theory. Results of reflection and transmission coefficients are validated by comparing with those available in literature. These structures with proper configurations are proved to be effective in attenuating waves by using Bragg reflection, and the triangular structures are found to be the best choices among the structures with same width and same area. Systematic calculations are then carried out for the triangular structures by varying the number, the draft, the width, the gap and the combination of width and gap of the structures to analyze their influences on the characteristics of Bragg reflection. The results are of reference values for design of the structures to attenuate waves based on the Bragg reflection.

Wei Luo,Lei Huang,Hao Chen,Limei Fang,Jin Huang,Zhinan Xu,Peilin Cen 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.5

A batch method was applied to investigate the adsorption behavior and mechanisms of L_tryptophan (Ltrp)on ion exchange resins. HZ-001 and JK006 were proved to be ideal adsorbents due to their large loading capacity and favorable selective adsorption for L-trp. Langmuir, Freundlich, and Dubinin-Radushkevich equations were applied to simulate the experimental data to describe the adsorption process of L_trp onto HZ_001 and JK006. The maximum loading capacity (at pH 5.0, 30 ℃), determined by the Langmuir and Dubinin-Radushkevich models, was close to each other (833 mg/g vs. 874 mg/g) for HZ_001, while discrepant (833 mg/g vs. 935 mg/g) for JK006. Three diffusion-controlled kinetic models were utilized to analyze the results in order to identify the adsorption mechanism. The adsorption kinetics of L_trp onto cation exchange resins was investigated under different experimental conditions, including initial solution pH, temperature, initial L-trp concentration, and adsorbent dosage. Moreover, the diffusion process of L_trp onto HZ_001 and JK006 was evaluated at different initial adsorbate concentrations. The thermodynamic parameters,obtained from the kinetic data, demonstrated that L-trp could be adsorbed spontaneously onto both resins.

Wei Luo,Limei Fan,Peilian Wei,Hao Chen,Limei Fang,Jin Huang,Zhinan Xu,Peilin Cen 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.5

Adsorption and desorption of L-tryptophan (L-trp) on strong acid cation exchange resin were investigated in a fixed-bed column. L-trp was effectively adsorbed onto the resin HZ-001, with the loading capacity and breakthrough time determined. Four kinetic models, including Adams-Bohard, Wolborska, Thomas, and Yoon-Nelson models,were adopted to determine the kinetic parameters of adsorption and to predict the breakthrough curves. The results showed that the models used described the breakthrough well. Desorption of L-trp from the column bed was performed using aqueous ammonia as the eluant. Optimum procedure was obtained with 2.0M aqueous ammonia at the elution velocity of 6 BV/h. Five cycles of adsorption-elution-regeneration were conducted to evaluate the column reutilization.

Huang, Wei,Wang, Lan-Ying,Fu, Yi-Le,Liu, Ji-Quan,Tao, You-Ni,Fan, Fang-Li,Zhai, Gao-Hong,Wen, Zhen-Yi Korean Chemical Society 2009 Bulletin of the Korean Chemical Society Vol.30 No.3

Aggregation behavior of three kinds of benzindocarbocyanine dyes in aqueous methanol solution was studied by UV-Vis absorption spectrum. The results indicated that the three dyes all existed monomer-dimer equilibrium in aqueous methanol solution (concentration range $10^{−5}\;to\;10^{−6}$ M) at 25.0$\sim$41.0 ${^{\circ}C}$ for Dye 1, 28.0$\sim$49.0 ${^{\circ}C}$ for Dye 2 and 26.0$\sim$47.0 ${^{\circ}C}$ for Dye 3. The fundamental property of the three dyes as the dimeric association constant KD, the dimeric free energy ${\Delta$}G_D, the dimeric entropy ${\Delta$}S_D, and the dimeric enthalpy ${\Delta$}H_D were determined. The ${\Delta$}H_D of three dyes: Dye 1, Dye 2 and Dye 3 was -42.5, -15.1 and -18.9 kJ/mol, respectively. The experimental observations were the subject of a theoretical study including the ground-state geometries which were fully optimized using DFT at B3LYP/6-31G level. The effect of dye molecule structure on ${\Delta$}H_D was discussed by theoretical calculations.
