BACKGROUND Hepatocellular carcinoma(HCC) is the third leading cause of death from malignant tumors worldwide. More than 50% of HCC cases occur in China. The prognosis remains poor and overall efficacy is still unsatisfactory. Chemotherapy resistance is the most important reason for the poor outcome. Much progress has been made in the study of chemotherapy resistance of HCC;however, the specific mechanisms of progression of HCC have still only been partially ***, the mechanism of chemotherapy resistance in HCC requires more *** To investigate the effect of miR-34 a expression on the growth inhibition of HepG2 cells by *** A recombinant lentiviral vector containing miR-34 a was constructed and transfected into HepG2 cells. The expression of miR-34 a was detected by reverse transcription-polymerase chain reaction(commonly known as RT-PCR) before and after transfection. Cells were exposed to 2 μM doxorubicin or phosphatebuffered saline before and after transfection. Cell viability in each group was detected by MTT assay, and cell cycle and apoptosis were detected by flow cytometry. Changes in expression levels of phospho(p)-p53, sirtuin(SIRT) 1,cyclin D1, cyclin-dependent kinase(CDK) 4, CDK6, BCL-2, multidrug resistance protein(MDR) 1/P glycoprotein(P-gp), and AXL were detected by Western *** Recombinant lentiviral vector LV-hsa-mir-34 a was successfully constructed by restriction endonuclease digestion and sequencing. RT-PCR showed that expression of miR-34 a in HepG2 cells was significantly upregulated after transfection(P < 0.01). MTT assay showed that growth of HepG2 cells was inhibited after upregulation of miR-34 a, and viability was significantly decreased after combined treatment with doxorubicin(P < 0.01). Flow cytometry showed that the number of HepG2 cells in G1 phase increased, and G1 phase arrest was more obvious after intervention with doxorubicin(P < 0.01). The apoptosis rate of HepG2 cells was incre

2009年和2015年中华人民共和国人力资源和社会保障部和国务院国有资产监督管理委员会先后出台了国有企业高管限薪规定,采取了绝对限薪和相对限薪两种不同方式,因此,有必要明晰哪一种方式更有利于促进国有企业高质量发展。以2010—2023年的A股国有企业为样本进行研究,结果表明:与绝对限薪相比,相对限薪更能够促进国有企业高质量发展,且相对限薪程度越高、内部控制质量越高,上述关系越明显。进一步研究发现,相对限薪促进国有企业发展质量提高是通过降低盈余管理、提高创新效率等路径实现的,且这种作用路径在产品市场竞争度高的国有企业和实体国有企业中更明显。研究结论对合理制定和有效实施限薪政策及提高企业内部控制质量,促进国有企业高质量发展具有启示意义。

Competitive adsorption of Cd, Cu, Hg and Pb by agricultural soils of the Changjiang and Zhujiang deltas in China

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第11期8卷 1808-1815页

Soils can often be contaminated simultaneously by more than one heavy metal. The sorption-desorption behavior of a metal in a soil will be affected by the presence of other metals. Therefore, selective retention and competitive adsorption of the soils to heavy metals can affect their availability and movement through the soils. In this study, the simultaneous competitive adsorption of four heavy metals (Cd, Cu, Hg, and Pb) on ten agricultural soils collected from the Changjiang and Zhujiang deltas, China was assessed. The results showed that the competition affected the behavior of heavy metal cations in such a way that the soils adsorbed less Cd and Hg, and more Pb and Cu with increasing total metal concentrations, regardless of the molar concen- tration applied. As the applied concentrations increased, Pb and Cu adsorption increased, while Cd and Hg adsorption decreased. The adsorption sequence most found was Pb>Cu>Hg>Cd. The maximum adsorption capacity for the heavy metal cations was calculated, and affected markedly by soil properties. The results suggest that Hg and Cd have higher mobility associated to the lower adsorption and that Pb and Cu present the opposite behavior. Significant correlations were found between the maximum adsorption capacity of the metals and pH value and exchangeable acid, suggesting that soil pH and exchangeable acid were key factors controlling the solubility and mobility of the metals in the agricultural soils.

The Abundance and Population Dynamics of Leptocybe invasa (Hymenoptera:Eulophidae) Galls on Eucalyptus *** China

引用

Journal of Integrative Agriculture 2012年第12期11卷 2116-2123页

作者： ZHU Fang-li REN shun-xiang QIU Bao-li HUANG zhen PENG zheng-qiang Engineering Research Center of Biological Control Ministry of Education/Department of Entomology South China Agricultural University Institute of Plant and Environment Protection Chinese Academy of Tropical Agricultural Science

The blue gum chalcid, Leptocybe invasa Fisher ＆ La Salle, invaded China in 2007 and has subsequently caused substantial damage to eucalyptus trees. In the current paper, we investigated the susceptibility of 10 Eucalyptus spp. and Eucahetus dunnii to L. invasa in the field, determined the density of galls as well as the gall volume on these tree species, and monitored the population dynamics of wasps in Hainan and Guangdong provinces of China. The order of susceptibility to L. invasa was Eucalyptus urophyllaxEucalyptus camaldulensis〉E, urophylla （coppices）〉Eucalyptus exserta〉 Eucalyptus grandisxE, urophylla in Hainan, and Eucalyptus propinqua〉Eucalyptus saligna〉E, exserta〉Eucalyptus microcorys〉Eucahetus dunnii〉E, camaldulensis〉Eucalyptus tereticornis〉Eucalyptus robust in Guangdong, China. Although L. invasa generally damages the midribs and petioles of young leaves and the tender bark of twigs of eucalyptus, galls were not observed on leaves of E. microcorys, E. camaldulensis, or E. dunnii. Gall volume significantly differed among the tree species, and gall volume and wasp number were positively correlated. In Dongfang, Hainan Province, the overwintering period of L. invasa emergencing through the year was from the end of December to March of the next year, and the number of population was the greatest on E. urophylla^E, camaldulensis, and the smallest on E. grandis E. urophylla. In Guangzhou, Guangdong Province, L. invasa hardly emerged in winter from December to June of the next year, and the population was the greatest on E. propinqua, and the smallest on E. microcorys.

以社会学理论视角为切入点,运用社会构成的经济、政治、社会交往、精神文化“四要素”分析框架进行系统分析可知,中等职业教育高质量发展要立足县域经济统筹发展,助力县域政治生态稳定,满足县域社会美好生活需要,创设县域良好文化环境。由此,从中等职业教育的发展理念、区域特色、功能定位、条件保障等方面寻求路径突破,提出推动县域中等职业教育“技能化”发展、“区域化”发展、“多元化”发展、“长效化”发展,从而为实现我国县域中等职业教育高质量发展提供理论支撑与政策依据。
