Effects of sodium ferulate on preventing steroid-induced femoral head osteonecrosis in rabbits

The aim of this study is to investigate the effects and possible mechanisms of sodium ferulate (SF) on anti-apoptosis in steroid-induced femoral head osteonecrosis in rabbits. Japanese white rabbits were randomly divided into three groups (control group, treatment group, and model group), each with 24 rabbits. The model and treatment groups were first injected with an intravenous dose of horse serum, 10 ml/kg, three weeks later with an intravenous dose of 7.5 ml/kg, and two weeks later with an intramuscular dose of methylprednisolone, 45 mg/kg, three times in order to establish rabbit models of osteonecrosis. Concurrently, the treatment group was injected with intravenous doses of SF 20 mg/kg for two weeks, once per day. Three time points, Weeks 2, 4, and 8, were selected after modeling was completed. Osteonecrosis was verified by histopathology with haematoxylin-eosin (HE) staining. The apoptosis rate of osteonecrosis was observed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The apoptosis expressions of caspase-3 and Bcl-2 were analyzed by immunohistochemistry and Western blot. The rabbit models of osteonecrosis were successfully established and observed by HE staining. SF was effective in intervening in apoptosis and decreasing the apoptosis rate in femoral head necrosis by the immunohistochemistry and TUNEL assay (P<0.01). Western blot analysis indicated that there were statistical significances in the protein levels of caspase-3 and Bcl-2 (P<0.01). SF has a protective effect by reducing the incidence of early steroid-induced femoral head necrosis in rabbits, effectively intervening in apoptosis through decreasing caspase-3 expression and up-regulating Bcl-2 expression.     

学科、学者与学术——关于档案学研究的哲学思考

档案学要用唯物主义的历史观去阐释过去发生的一切,即便是在浮躁的市场氛围中,也应保持自己的专业操守,保持一份必要的职业冷静。当前,我们对档案管理实践的研究,要特别注意遵循马克思主义哲学的普遍原则,理论联系实际,解决档案管理工作中的关键问题,全局问题。     

Moisture Adsorption Mechanism of Earthen Plaster Containing Soluble Salts in the Mogao Grottoes of China

ABSTRACT

In the Mogao Grottoes of Dunhuang, China, the ambient relative humidity (RH) fluctuation in the caves is the main cause for the deterioration that has been observed, especially the deterioration of the earthen plaster and wall paintings linked to the presence of NaCl and Na₂SO₄ salt contaminants. To help identify the mechanism responsible for this salt-related deterioration and provide a theoretical basis for the development of a preventive conservation regime, this study addressed the basic moisture adsorption mechanisms of earthen plaster with soluble salts by taking an experimental approach. It is shown that, as ambient RH increases, the moisture adsorption process of the plaster containing the soluble salts can be regarded to have three basic stages, as evidenced by the results of the moisture adsorption tests performed on earthen plaster samples with different NaCl or Na₂SO₄ contents at various humidity levels. The moisture adsorption mechanism and its determining factors at each stage are also analysed. In addition, it is suggested that the hygroscopicity of the plaster structure and the interaction between the different kinds of salts in the plaster, which makes the dissolution or hydration of the salt in the plaster pores much easier, should be considered more seriously regarding increases in the ambient RH in the caves.     

"大阅读"活动的发展历程及特点分析

“大阅读”活动是一类阅读活动的统称,倡导通过阅读提升社区、社群的氛围,形成社区、社群的凝聚力,从而建设书香社会.它最早起源于英国,随后兴盛于美国,并逐步影响全世界,形成一个世界范围内广泛而持续不断的阅读热潮.“大阅读”活动的组织机构不一,有的由单一的传媒组织推动,也有的由阅读推广组织、传媒组织和图书情报机构等联合推动.通过对“大阅读”活动的发展历程及特点的总结、分析,将对我国开展“大阅读”活动、建设书香社会提供可资借鉴的启示.
