OBJECTIVE: To critically appraise the methodological quality of clinical practice guidelines for headache produced over the last two decades, including those covering specific interventions using Traditional Chinese ***: The guidelines on headache disorders were obtained by searching a number of databases, including Pub Med, EMBASE, Web of Science,Chinese Biomedical Literature Database, China National Knowledge Infrastructure Database, China Science and Technology Journal Database, and Wanfang database, three guideline-related databases [Guideline-International Network, National Guideline Clearinghouse, and Medlive], and the records of organizations that develop guidelines. The publication date was limited to the period from January 1996 to June 2015. The search terms "headache", "headache disorders", "cephalalgia", "migraine", "tension-type headache", "practice guideline", "consensus ", "statement", "regulation", and "recommendation" were used in the "Me SH" and "Free-text" fields. The guidelines were independently appraised by four researchers using the Appraisal of Guidelines for Research and Evaluation Ⅱ ***: A total of 23 guidelines published between 1998 and 2014 were reviewed. The overall consistency of the four appraisers was good [interclass correlation coefficient 0.84; 95% confidence interval(CI) 0.82-0.86]. The mean(standard deviation) scores for scope and purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability, and editorial independence were 52.1(18.0), 39.5(17.1), 33.4(21.0), 49.8(21.9),23.8(19.3), and 24.2(23.7). Only two guidelines were recommended, 12 were recommended with modification, and nine were not ***: Physical Traditional Chinese Medicine therapies were recommended to treat headache. The overall quality of headache guidelines was low in China, but evidence-based guidelines are gradually becoming mainstream. Guideline developers should carefully consider, i

The divergence and continuous evolution of plants and animals contribute to ecological *** and transcription factors(TFs) are key determinants of gene regulation and transcription ***,theevolutionary trajectories and relationships of promoters and TFs are still poorly understood. Here, we conducted extensive analysis of large-scale multi-omics sequences in 420 animal species and 223 plant species spanning nearly a billion years of evolutionary history. Results showed that promoter GC-contentandTFisoelectricpoints,as features/signatures that accompany long biological evolution, exhibited increasing growth in animal cells but a decreasing trend in plant cells. Furthermore, the evolutionary trajectories of promoter and TF signatures in the animal kingdom provided further evidence that Mammalia as well as Aves evolved directly from the ancestor Reptilia. The strong correlation between promoter and TF signatures indicates that promoters and TFs formed antagonistic coevolution in the animal kingdom, but mutualistic coevolution in the plant kingdom. The distinct coevolutionary patterns potentially drive the plant-animal divergence, divergent evolution and ecological diversity.

The successful construction of highly stable and active platinum nanoparticles(Pt NPs) within the confined cavity of a threedimensional porphyrinic nanocage is presented in this study. The flexible porphyrinic nanocage containing eight N-heterocyclic carbene(NHC) precursors was prepared using a metal-carbene-templated ring-closing metathesis(RCM) approach as new capping materials for the fabrication/stabilization of Pt NPs. Notably, the NHC-stabilized Pt NPs within the porphyrinic nanocage exhibited high catalytic activity for selective oxidation of 2-chloroethyl ethyl sulfide to nontoxic 2-chloroethyl ethyl sulfoxide with excellent stability and recyclability.

This article concentrates on the investigation of hot deformation behavior of conventionally rolled commercial grade AA5083 alloy （A1-4. 5Mg）, for automotive and aviation applications. The superplastic response of the alloy was investigated at high strain rates （ 1〉10-3 s-I） , and a temperature range of 400℃to 550 ℃. An elongation to failure of 201% was achieved at low temperature （425 ℃ ） and high strain rate （ 10-2s-1 ）, which indicates sufficient ductility under hot deformation for manufacturing of extremely complex shapes using superplastic forming technology. Furthermore, the alloy exhibited a maximum elongation of about 470% at strain rate of 10-3s-1 and a temperature of 525℃. The deformation and failure mechanisms at both the critical conditions were studied as a function of strain rate and temperature. The contributions of strain-rate sensitivity and strain hardening were analyzed in relation to the observed tensile ductilities. Deformation mechanism of the alloy was also investigated with reference to Strain rate sensitivity index （m） and Activation energy （Q） for the given test condition. Empirical calculations reveal that dominant deformation mechanism responsible for hot deformation of the alloy is grain boundary sliding （ GBS）, which is further supported by deformed surface examination using scanning electron microscopy （SEM）. Fracture surfaces of the samples deformed to failure, at relatively higher and lower strain rates, was examined to investigate the micro- mechanisms governing failure. Phenomenon of cavity nucleation, growth and coalescence was observed to be the failure mechanism in the investigated alloy.
