Background Myocardial infarction （MI） has likely contributed to the increased prevalence of heart failure （HF）. As a result of re- duced cardiac function, splanchnic blood flow decreases, causing ischemia in villi and damage to the intestinal barrier. The induction of heme oxygenase-1 （HO-1） could prevent, or lessen the effects of stress and inflammation. Thus, the effect and mechanism thereof of HO-1 on the intestines of rats with HF was investigated. Methods Male Wistar rats with heart failure through ligation of the left coronary artery were identified with an left ventricular ejection fraction of 〈 45% through echocardiography and then divided into various experimental groups based on the type of peritoneal injection they received [MI： saline; MI ＋ Cobalt protoporphyrin （CoPP）： CoPP solution; and MI ＋ Tin mesoporphyrin IX dichloride （SnMP）： SnMP solution]. The control group was comprised of rats without coronary ligation. Echocardiogra- phy was performed before ligation for a baseline and eight weeks after ligation in order to evaluate the cardiac function of the rats. The bac- terial translocation （BT） incidence, mesenteric microcirculation, amount of endotoxins in the vein serum, ileum levels of HO- 1, carbon oxide （CO）, nitric oxide （NO）, intedeuldn （IL）-10, turnour necrosis factor-et （TNF-ct）, and the ileum morphology were determined eight weeks after the operation. Results The rats receiving MI ＋ CoPP injections exhibited a recovery in cardiac function, an amelioration of mesenteric microcirculation and change in morphology, a lower BT incidence, a reduction in serum and ileac NO and TNF-ct levels, and an elevation in ileac HO-1, CO, and interleukin-10 （[L-10） levels compared to the MI group （P 〈 0.05）. The rats that received the MI ＋ SnMP injections exhibited results inverse to the MI （P 〈 0.05） group. Conclusions HO-1 exerted a protective effect on the intestines of rats with HF by inhibiting the inflammation and amelioration of microcirculation through t

Viral protein R(Vpr) plays an important role in the replication and pathogenesis of Human immunodeficiency virus type 1(HIV-1). Some of the various functions attributed to Vpr, including the induction of G2/M cell cycle arrest, activating the NF-κB pathway, and promoting viral reverse transcription, might be interrelated. To test this hypothesis, a panel of Vpr mutants were investigated for their ability to induce G2/M arrest and to activate the NF-κB pathway. The results showed that the Vpr mutants that failed to activate NF-κB also lost the activity to induce G2/M arrest, which suggests that inducing G2/M arrest via Vpr depends at least partially on the activation of NF-κB. This latter possibility is supported by data showing that knocking down the key factors in the NF-κB pathway – p65, Rel B, IKKα, or IKKβ– partially rescued the G2/M arrest induced by *** results suggest that the NF-κB pathway is probably involved in Vpr-induced G2/M cell cycle arrest.

Osteoporosis is a frequent complication of chronic inflammatory diseases and increases in the pro-inflammatory cytokines make an important contribution to bone loss by promoting bone resorption and impairing bone formation. Omentin-1 is a newly identified adipocytokine that has anti-inflammatory effects, but little is known about the role of omentin-1 in inflammatory osteoporosis. Here we generated global omentin-1 knockout（omentin-1^-/-） mice and demonstrated that depletion of omentin-1 induces inflammatory bone loss-like phenotypes in mice, as defined by abnormally elevated pro-inflammatory cytokines, increased osteoclast formation and bone tissue destruction, as well as impaired osteogenic activities. Using an inflammatory cell model induced by tumor necrosis factor-α（TNF-α）, we determined that recombinant omentin-1 reduces the production of proinflammatory factors in the TNF-α-activated macrophages, and suppresses their anti-osteoblastic and pro-osteoclastic abilities. In the magnesium silicate-induced inflammatory osteoporosis mouse model, the systemic administration of adenoviral-delivered omentin-1 significantly protects from osteoporotic bone loss and inflammation. Our study suggests that omentin-1 can be used as a promising therapeutic agent for the prevention or treatment of inflammatory bone diseases by downregulating the proinflammatory cytokines.

伴随着经济的高速发展,文化生活市场化、电子化、网络化的程度愈演愈烈,而传统戏曲文化面临的危机却越来越难以挽回。然而,传统戏曲在所谓的"草根阶层",仍然保存着旺盛的生命力。民间戏曲爱好者在人员构成、组织形式、心理动因、审美意向、文化内涵等方面拥有独自的特点。非功利的艺术诉求、质朴纯真的生命美学、深厚温馨的家园情结、抱团取暖的修禊意识是其丰厚的文化底蕴。"礼失求诸野",充分发掘底层民众的戏曲文化内涵可以从根本上繁荣民族传统戏曲文化提供有益的借鉴。

We propose a new description scheme for MPEG-7:Generic-model-based Description Scheme to describe contents of audio, video, text and other sorts of multimedia. It uses a generic model as the description frame, which provides a simple but useful object\|based structure. The main components of the description scheme are generic model, objects and object features. The proposed description scheme is illustrated and exemplified by Extensible Markup Language. It aims at clarity and flexibility to support MPEG\|7 applications such as query and edit. We demonstrate its feasibility and efficiency by presenting applications: Digital Broadcasting and Edit System (DEBS) and Non\|linear Edit System (NLES) that already used the generic structure or will greatly benefit from it.

In order to further improve the transfection efficiency of hydroxyapatite nanoparticle （HAp）, arginine functionalized hydroxyapatite （HAp/Arg） was synthesized by hydrothermal synthesis. The morphology, crystallite size and zeta potential of the HAp/Arg were characterized by transmission electron microscopy （TEM）, atomic force microscopy （AFM） and zeta potential analyzer. The loading and protecting properties of HAp/Arg to DNA were tested by electrophoresis. Its cytotoxicity was also measured in Hela cells and HAEC cells by MTT and LDH, and its transfection efficiency was examined by fluorescence microscope and flow cytometry. The results reveal that HAp/Arg is short rod-like and nano single crystal, the mean diameter is 50-90 nm and zeta potential is 35.8 mV at pH 7.4. HAp/Arg to DNA can be condensed by electrostatic effect and protect DNA against degradation in DNase I, and shows high transfection efficiency without cytotoxicity. These results suggest that HAp/Arg can be a promising alternative as a novel gene delivery system.
