Research on corporate social responsibility is a hot topic in the financial field recently. Domestic and foreign scholars have conducted some researches on the impact of CSR on investment and financing, but the special institutional background of China has not been considered. Based on the background of Chinese enterprise system, this paper introduces the property right nature and analyzes the role of Chinese enterprises with different ownership nature in fulfilling social responsibility on the investment scale. Also cash as the most liquid asset is the core component of corporate governance. There are three conclusions and four policy recommendations. The first conclusions is an enterprise's active fulfillment of social responsibility will increase its investment scale. Second in state-owned enterprises, fulfilling social responsibilities has a more significant effect on the improvement of enterprise investment scale. And final conclusions is Corporate cash holdings will improve the impact of corporate social responsibility on corporate investment scale.The first policy recommendations is the government should promote listed companies to actively fulfill their social responsibilities.Secnd Listed companies should strengthen their awareness of social responsibility.Third Private enterprises should not only pay attention to their economic development, but also actively fulfill their social responsibilities.Fourth Enterprises should retain sufficient cash flow, which will have a positive impact on fulfilling corporate social responsibility, ultimately increasing investment scale and improving corporate performance.

Cuiping Li,Weidong Jiang,Yang Zhou,Xuanping Huang,Nuo Zhou 한국응용생명화학회 2020 Applied Biological Chemistry (Appl Biol Chem) Vol.63 No.2

Platelet factor-4 variant 1 (PF4V1) was recently described as a natural non-allelic gene variant of platelet factor-4 (PF4), which has been closely associated with the growth and metastasis of various cancers. Our previous research showed that PF4V1 was related to oral squamous cells carcinoma (OSCC) metastasis. Howerver, it is still not clear about the functional role of PF4V1 in OSCC. In this study, stably transfected cell lines were constructed and the expression level of PF4V1 was verified by real‐time polymerase chain reaction (RT-PCR) and western blot. The effect of PF4V1 on proliferation, migration, invasion, and apoptosis of oral cancer (OC) cells were detected. Moreover, a xenograft tumor model was constructed to evaluate the effect of PF4V1 on OSCC in vivo. Indicators of Wnt/β-catenin, angiogenesis and epithelial-mesenchymal transition (EMT) pathways were also examined. Stable cell lines with overexpression and inhibited expression of PF4V1 were constructed successfully. After stable transfection, PF4V1 significantly promoted the proliferation, migration, and invasion of OC cells in vitro, and their tumor formation in vivo. Furthermore, PF4V1 remarkably promoted the expression of β-catenin, VEGF, and FGF but suppressed the expression of GSK-3β. There was no statistically significant correlation between PF4V1 and EMT pathway. This study provides evidence that PF4V1 promotes the proliferation, migration, invasion and tumor formation of OC cells by regulating the Wnt/β-catenin pathway and angiogenesis. Our findings suggest that PF4V1 could be a very promising target of OSCC therapy in the future.

Micromechanical investigation of thermal stresses of a finite plane containing multiple elliptical inclusions based on the equivalent inclusion method and distributed dislocation method

Jiong Zhang,Yunhai Huang,Weidong Liu,Liankun Wang,Chao Yang,Lin Zuo 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.1

This paper presents a micromechanical method to analyze the thermal stresses in a finite plane containing multiple elliptical inclusions. Firstly, the Eshelby’s equivalent inclusion method is employed to solve the elastic fields of a two-dimensional infinite plane containing multiple elliptical inclusions under a uniform temperature change. Both the interior Eshelby’s tensor and the exterior Eshelby’s tensor are employed. Then the boundary of the plane is modeled by continuous distributions of dislocation densities. By combining the two steps, a system of singular integral equations is formulated based on the traction-free boundary condition. Then the thermal stresses of the plane can be obtained by the superposition of the stresses obtained by the Eshelby’s equivalent inclusion method and distributed dislocation method. Additionally, some examples are given to show the effects of the presented method. The effects of the material constants, geometric parameters and fiber packing arrangement on the thermal stresses are also studied.

Multi-objective optimization of cycloidal gear based on segmental modification of pressure angle

Yinghui Zhang,JinYong Huang,Weidong He 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.7

In order to get the optimal profile of cycloid gear after sectional modification, a multi-objective optimization design method is proposed that considers both the modification parameters and macro-parameters of the cycloid gear. An algorithm of meshing force, meshing efficiency and anti-gluing ability between the cycloid gear and the pin gear was derived, and the related independent parameters were extracted as optimization variables. Taking high efficiency, high strength and light weight as the objective, the mathematical models of doubleobjective and three-objective optimization were established, and the influence of key design variable on the objective function was analyzed, and NSGA-II multi-objective genetic algorithm was used to solve the Pareto optimal solution of the optimization mathematical model. Results show that the optimized parameters can significantly improve the meshing efficiency, reduce the volume and meet the design requirements of high strength, high efficiency and lightweight on the premise of ensuring the strength of cycloid gear surface.

Hanlin Wang,Jiexun Huang,Weidong Huang,Longyuan Yang 대한화학회 2023 Bulletin of the Korean Chemical Society Vol.44 No.1

A fluorescence enhancement probe 2-[2-(1,3-benzothiazol-2-yl)phenyl]-1H- isoin-dole-1,3(2H)-dione (HL1) for N2H4 was synthesized and characterized by using 2-(2-aminophenyl)benzothiazole as a fluorophore, and its spectroscopic properties had been researched. The results exhibited that HL1 was highly selective and sensitive to N2H4, and it had the excellent anti-interference ability and displayed a fast response. The fluorescent intensity of HL1 showed a good linear relationship with the concentration of N2H4 (1.5–12.5 μmolL1), and its detection limit was 0.12 μmol/L. In addition, HL1 was also applied for determin- ing N2H4 levels in real water samples and imaging N2H4 in living HeLa cells.

Functional Characterization of Arabidopsis thaliana WRKY39 in Heat Stress

Shujia Li,Xiang Zhou,Ligang Chen,Weidong Huang,Diqiu Yu 한국분자세포생물학회 2010 Molecules and cells Vol.29 No.5

Arabidopsis thaliana WRKY39, a transcription factor that is induced by heat stress, is a member of the group II WRKY proteins and responds to both abiotic and biotic stress. Heat-treated seeds and plants of WRKY39 knock-down mutants had increased susceptibility to heat stress, show-ing reduced germination, decreased survival, and elevated electrolyte leakage compared with wild-type plants. In con-trast, WRKY39 over-expressing plants exhibited enhanced thermotolerance compared with wild-type plants. RT-PCR and qRT-PCR analysis of wrky39 mutants and WRKY39 over-expressing plants identified putative genes regulated by WRKY39. Consistent with a role for WRKY39 in heat tolerance, the expression levels of salicylic acid (SA)-regulated PR1 and SA-related MBF1c genes were down-regulated in wrky39 mutants. In contrast, over-expression of WRKY39 increased the expression of PR1 and MBF1c. The WRKY39 transcript was induced in response to treat-ment with SA or methyljasmonate. Analysis of heat stress-induced WRKY39 in defense signaling mutants, including coi1, ein2, and sid2, further indicated that WRKY39 was positively co-regulated by the SA and jasmonate (JA) sig-naling pathways. Together, these findings reveal that heat stress-induced WRKY39 positively regulates the coopera-tion between the SA- and JA-activated signaling pathways that mediate responses to heat stress.
