1如何撰写循证临床综述显示文摘传统临床综述不同于系统评价和Meta分析。临床综述是在广泛讨论某一主题时选择性评价医学文献;非定量系统评价则全面评价医学文献,收集并综合所有相关信息以形成最佳诊疗方案;而Meta分析(即定量系统评价)是采用严格的统计学方法分析汇总的研究资料,以回答某一具体的临床问题。本文旨在为《美国家庭医生》撰写循证临床综述提供指南。首先,主题应与家庭医疗实践相关,并能引起普遍兴趣。接着,用表格列出综述的继续医学教育目标。描述文献检索过程,列举循证医学评价的多种来源,如Cochrane协作网、BMJ临床证据网或InfoRetriever网。尽可能使用与发病率、病死率或生活质量相关的临床结局证据及基于初级保健人群研究的证据。向《美国家庭医生》投稿时,应根据以下标准划分支持重要建议的证据级别:A级,随机对照试验(RCT)、Meta分析;B级,其它证据;C级,共识/专家意见。最后,还应提供一份要点总结表。Jay Siwek Margaret L.

3Seed Zone Properties and Crop Performance as Affected by Three No-Till Seeders for Permanent Raised Beds in Arid Northwest China显示文摘The no-till seeders of various soil opener configurations have been shown to produce various soil physical responses in relation to soil and climate conditions, thus affecting crop performance in permanent raised beds (PRB) systems. This is particularly important in arid Northwest China where large volumes of residue are retained on the soil surface after harvest. In Zhangye, Gansu Province, China, a field trial assessed the effects of three typical (powered-chopper, powered-cutter and powered-disc) PRB no-till seeders and one traditional seeder on soil disturbance, residue cover index, bulk density, fuel consumption, plant growth, and subsequent yield. In general, seedbed conditions and crop performance for PRB no- till seeders seeded plots were better than for traditional seeded plots. In PRB cropping system, the powered-chopper seeder decreased mean soil disturbance and increased residue cover index compared to powered-disc and -cutter seeders. However, the results indicated that soil bulk density was 2.3-4.8% higher, soil temperature was 0.2-0.6℃ lower, and spring wheat emergence was 3.2-4.7% less. This was attributed to greater levels of residue cover and firmer seedbeds. Spring maize and wheat performance in the powered-cutter and -disc treatments was better (non-significant) than powered-chopper treatment. So powered disc no-till seeder, which generally provided the best planting condition and the highest yield, appeared to be the suitable seeder in heavy residue cover conditions. Considering the precision requirements for soil disturbance and residue cover, the powered strip-chopping no-till seeder could be a suitable option for PRB cropping system in Northwest China. Although these results are preliminary, they are still valuable for the design and selection of no-till seeders for PRB cropping systems in arid Northwest China.HE Jin LI Hong-wen Allen David McHugh WANG Qing-jie LI Hui Rabi Gautam Rasaily Khokan Kumer Sarker 2012Journal of Integrative Agriculture2012,11,10:5
4Reference quality assembly of the 3.5-Gb genome of Capsicum annuum from a single linked-read library显示文摘Linked-Read sequencing technology has recently been employed successfully for de novo assembly of human genomes,however,the utility of this technology for complex plant genomes is unproven.We evaluated the technology for this purpose by sequencing the 3.5-gigabase(Gb)diploid pepper(Capsicum annuum)genome with a single Linked-Read library.Plant genomes,including pepper,are characterized by long,highly similar repetitive sequences.Accordingly,significant effort is used to ensure that the sequenced plant is highly homozygous and the resulting assembly is a haploid consensus.With a phased assembly approach,we targeted a heterozygous F1 derived from a wide cross to assess the ability to derive both haplotypes and characterize a pungency gene with a large insertion/deletion.The Supernova software generated a highly ordered,more contiguous sequence assembly than all currently available C.annuum reference genomes.Over 83%of the final assembly was anchored and oriented using four publicly available de novo linkage maps.A comparison of the annotation of conserved eukaryotic genes indicated the completeness of assembly.The validity of the phased assembly is further demonstrated with the complete recovery of both 2.5-Kb insertion/deletion haplotypes of the PUN1 locus in the F1 sample that represents pungent and nonpungent peppers,as well as nearly full recovery of the BUSCO2 gene set within each of the two haplotypes.The most contiguous pepper genome assembly to date has been generated which demonstrates that Linked-Read library technology provides a tool to de novo assemble complex highly repetitive heterozygous plant genomes.This technology can provide an opportunity to cost-effectively develop high-quality genome assemblies for other complex plants and compare structural and gene differences through accurate haplotype reconstruction.Amanda M.Hulse-Kemp Shamoni Maheshwari Kevin Stoffel Theresa A.Hill David Jaffe Stephen R.Williams Neil Weisenfeld Srividya Ramakrishnan Vijay Kumar Preyas Shah Michael C.Schatz Deanna M.Church Allen Van Deynze 2018Horticulture Research2018,5,1:4

17Source-sink relations and responses to sink-source manipulations during grain filling in wheat显示文摘The source-sink ratio during grain filling is a critical factor that affects crop yield in wheat,and the main objective of this study was to determine the source-sink relations at both the canopy scale and the individual culm level under two nitrogen(N)levels at the post-jointing stage.Nine widely-used cultivars were chosen for analyzing source-sink relations in southwestern China;and three typical cultivars of different plant types were subjected to artificial manipulation of the grain-filling source-sink ratio to supplement crop growth measurements.A field experiment was conducted over two consecutive seasons under two N rates(N+,150 kg ha^(-1);N-,60 kg ha^(-1)),and three manipulations were imposed after anthesis:control(Ct),removal of flag and penultimate leaves(Lr)and removal of spikelets on one side of each spike(Sr).The results showed that the single grain weights in the three cultivars were significantly decreased by Lr and increased by Sr,which demonstrated that wheat grain yield potential seems more source-limited than sink-limited during grain filling,but the source-sink balance was obviously changed by climatic variations and N deficient environments.Grain yield was highly associated with sink capacity(SICA),grain number,biomass,SPAD values,and leaf area index during grain filling,indicating a higher degree of source limitation with an increase in sink capacity.Therefore,source limitation should be taken into account by breeders when SICA is increased,especially under non-limiting conditions.Chuanmai 104,a half-compact type with a mid-sized spike and a long narrow upper leaf,showed relatively better performance in source-sink relations.Since this cultivar showed the characteristics of a lower reduction in grain weight after Lr,a larger increase after Sr,and a lower reduction in post-anthesis dry matter accumulation,then the greater current photosynthesis during grain filling contributed to the grain after source and sink manipulation.WU Xiao-li LIU Miao LI Chao-su Allen David(Jack)MCHUGH LI Ming XIONG Tao LIU Yu-bin TANG Yong-lu 2022Journal of Integrative Agriculture2022,21,6:2
