The high fire safety of polymer nanocomposites is being pursued by research institutions around the *** addition to intrinsic flame retardancy strategy,the additive-type flame retardants have attracted increasing attention due to low commercial cost and easy fabrication ***,traditional additive-type flame retardants usually need high addition amount to achieve a desirable effect which causes many side-effects on the overall performance of polymer materials,such as deteriorated mechanical property and *** present two-dimensional(2D)nanomaterials have also been applied to reduce the fire hazards of polymer(nano)composites with the coupling of barrier function and catalysis as well as carbonization *** though most research work mainly focus on graphene-based flame retardants,more emerging two-dimensional nanomaterials are taking away research attention,due to their complementary and unique properties,mainly including hexagonal boron nitride(h-BN),molybdenum disulfide(MoS2),metal organic frameworks(MOF),carbon nitride(CN),titanium carbide(MXene)and black phosphorene(BP).In this review,except for graphene,the flame retardant mechanism involving different layered nanomaterials are also ***,the functionalization method and flame retardancy effect of different layered nanomaterials are emphatically discussed for offering an effective reference to solve the fire hazards of polymer ***,this work objectively evaluates the practical significance of polymer/layered nanomaterials composites for industrial application.

Currently, T cells dedicated to medi- ating immunosuppression and homeostasis are called regulatory T （Treg） cells. Treg cells are closely assoc- iated with infection, allergy, autoimmunity, tumor immunity, fetal-maternal tolerance, and organ transplantation. Treg cells exert their immunosuppressive functions by directly killing or inhibiting T cells and antigen-presenting cells （dendritic cells, macrophages,

Microporous titanium dioxide thin films have been grown on titanium plates by the micro-plasma oxidation method with different current densities (4, 6, 10 and 14 A/dm2). X-ray diffraction, scanning electronic microscopy and UV-Vis spectrophotometry were used to characterize the films. It is found that the films grown are microporous and consist of crystalline titanium dioxide. The micropore size and the content of anatase and rutile TiO2 phase increase with the applied voltage. The relatively higher degradation efficiency for rhodamine B is obtained in the film produced with a current density of 10 A/dm2.

In contrast to grassland and forest ecosystems, little is known about insect response to nitrogen deposition in agricultural ecosystems. This study was carried out to investigate the effects of short-term （1-2 years） nitrogen application （0, 172.5, 345.0, 690.0, and 1035.0 kg · N ha^-1 · y^-1） on beetle communities in tea plantations. A collection of 34 families, 89 species of beetles, was obtained from a tea plantation in Wuyishan, China. Among them, herbivores, predators and detritivores had 52, 29, and eight species, respectively. Species richness, effective diversity and abundance （measured as the number of individuals and insect biomass） of the beetle community were not significantly related to the rate of nitrogen application. However, nitrogen application changed the species distribution and weakly increased the evenness of species distribution, while this did not significantly change the species evenness. Species richness and abundance of herbivores and predators were not significantly related to the rate of nitrogen application. However, there were some variations in trophic responses to nitrogen. Species richness and abundance of detritivores increased with increasing nitrogen application.

As one of the facultatively intracellular bacteria, Salmonella enterica serovarTyphimurium （S. Typhimurium） replicates even in macrophages and induces their death--a key strategy of this virulent patho- gen in evading the innate immune response.1 The underlying mechanisms are well known but complex, because many pathways are involved, such as apoptosis,2 necrosis,3 pyr- optosis4 and autophagy,s In a recent issue of Nature Immunology, Robinson et al. reveal a novel pathway for killing macrophages dur- ing infection： type 1 interferon- （IFN-α and IFN-β associated necroptosis.6

Background Vaginal myomectomy was firstly reported in 1994, however, it is a relatively new technique in China. The feasibility and safety of the procedure is still controversial in this country. The aim of this study was to analyze the outcomes of vaginal myomectomy in 90 patients and to investigate the feasibility and safety of the surgery. Methods From June 2001 to June 2004, 90 patients with uterine leiomyoma were treated with vaginal myomectomy in our hospital （vaginal group）. The indications, operative performance, postoperative complications, and recovery of the patients were analyzed and compared with those of 93 patients with uterine leiomyoma treated by laparotomic myomectomy from January 2000 to January 2001 （laparotomy group）. The Student＇s t test was used to compare the continuous variables between the two groups, and the chi-square test was used to compare the categorical variables. The vaginal and laparotomy groups were followed up for 10-34 months （median, 21） and 15-24 months （median, 30）, respectively. Results Vaginal myomectomy was performed successfully in 87 of the 90 patients （96.7%）. In the other 3 patients, the procedure failed and laparotomy was carded out. In both groups, the uterus was enlarged to 8-16 weeks gestational size （median, 10 gestational weeks）. The number of resected tumors was 1 - 12 （median, 2） in the vaginal group and 1-15 （median, 4） in the laparotomy group, respectively （P〉0.05）. The mean operating time, intraoperative blood loss, and postoperative hospital stay were （52± 21） minutes, （230± 44） ml, and （7.0±1.2） days in the vaginal group, and （654±32） minutes, （200±56） ml, and （7.04±1.5） days in the laparotomy group （P〉0.05）. The mean top postoperative temperature was （38.44±1.1）℃ and （37.8±0.6）℃ in the two groups respectively （P〈0.05）. Both groups had one recurrent case during the follow-up （P〉0.05）. Condusions Vaginal myomectomy is feasible and safe in treating uterine leiomyoma. To some extent, it is superior to laparot
