Bacteria need a high degree of genetic stability to maintain their species identities over long evolutionary times while retaining some mutability to adapt to the changing environment.It is a long unanswered question that how bacteria reconcile these seemingly contradictory biological properties.We hypothesized that certain mechanisms must maintain a dynamic balance between genetic stability and mutability for the survival and evolution of bacterial species.To identify such mechanisms,we analyzed bacterial genomes,focusing on the Salmonella mismatch repair(MMR)system.We found that the MMR gene mutL functions as a genetic switch through a slipped-strand mispairing mechanism,modulating and maintaining a dynamic balance between genetic stability and mutability during bacterial evolution.This mechanism allows bacteria to maintain their phylogenetic status,while also adapting to changing environments by acquiring novel traits.In this review,we outline the history of research into this genetic switch,from its discovery to the latest findings,and discuss its potential roles in the genomic evolution of bacteria.

调节控制负荷侧协同消纳新能源是新型电力系统下的关键技术之一。考虑到热电联产机组的以热定电工作方式,加剧了热电耦合效应,提出了利用碳捕集技术辅之电制热负荷为热电联产机组提供辅热的优化调度策略。首先,分析多元系统电力电量平衡关系,建立碳捕集设备和热电联产的运行特性模型;其次,考虑碳捕集和电制热负荷无极调节优势及运行边界,建立了考虑弃风成本、碳交易成本的含CHP-CCS的综合能源系统优化调度模型;最后,以中国北方某城市冬季供暖期为例,利用CPLEX进行数值分析。仿真结果表明,该方法能够提升系统经济性和新能源消纳率,同时达到了减少碳排放量的目的。

心悸为临床常见病证之一,张仲景于《伤寒论杂病论》中论述了心悸的病机证治。张仲景重视脾胃在发病和辨证论治中的重要作用,书中多见顾护脾胃的学术思想。本文总结《伤寒杂病论》中心悸相关条文,明确了心悸的病因病机和中焦脾胃功能的密切关系。脾胃功能的健旺与否是心脏发挥正常功能的基础,亦是心悸发生的重要影响因素。心悸之本在于中焦脾胃功能失常,治疗当以调理中焦脾胃为中心,兼顾心、肝、肾等脏腑功能。

Near UV highly luminescent colloidal Cs_(2)NaBiCl_(6)nanocrystals(NCs)were synthesized by a simple low-cost ligand-assisted reprecipitation method.In our strategy,metal chloride precursors were added to the mixture of anti-solvent and ligand at room-temperature.The obtained Cs_(2)NaBiCl_(6)NCs exhibited a bright blue emission with significantly improved photoluminescence quantum yield(PLQY)of 39.05%.The optical properties and stability were greatly enhanced by doping Sb where Cs_(2)NaBi_(0.75)Sb_(0.25)Cl_(6)showed a high PLQY of 46.57%,and both the powder and the colloidal solution exhibited superior stability.

For efficient solid-state refrigeration technologies based on electrocaloric effect(ECE),it is a great challenge of simultaneously obtaining a large adiabatic temperature change(DT)within a wide temperature span(Tspan)in lead-free ferroelectric ceramics.Here,we studied the electrocaloric effect(ECE)in(1-x)(Na_(0.5)Bi_(0.5))TiO_(3)-xCaTiO_(3)((1-x)NBT-xCT)and explored the combining effect of morphotropic phase boundary(MPB)and relaxor feature.The addition of CT not only constructs a MPB region with the coexistence of rhombohedral and orthorhombic phases,but also enhances the relaxor feature.The ECE peak appears around the freezing temperature(Tf),and shifts toward to lower temperature with the increasing CT amount.The directly measured ECE result shows that the ceramic of x=0.10,which is in the MPB region,has an optimal ECE property of DTmax=1.28 K@60℃under 60 kV/cm with a wide Tspan of 65C.The enhanced ECE originates from the electric-field-induced transition between more types of polar nanoregions and long-range ferroelectric macrodomains.For the composition with more relaxor feature in the MPB region,such as x?0.12,the ECE is relatively weak under low electric fields but it exhibits a sharp increment under a sufficiently high electric field.This work provides a guideline to develop the solidestate cooling devices for electronic components.

目的:探讨一氧化碳(CO)中毒患者早期中毒程度与血小板与淋巴细胞比值(PLR)、中性粒细胞与淋巴细胞比值(NLR)的关系。方法:选取本院2014年6月至2017年6月收治的160例CO早期中毒患者(观察组),依据患者中毒严重程度分为轻度组(n=43)、中度组(n=92)和重度组(n=25),另选取160例的健康体检者作为对照组,统计各组患者中性粒细胞、血小板、白细胞和淋巴细胞等计数;显微镜下观察各组中性粒细胞、血小板的形态变化,并分类200个中性粒细胞计算核突积分和毒性指数;计算各组患者PLR和NLR水平,Logistic回归模型分析PLR、NLR与CO中毒的关系。结果:不同程度早期CO中毒患者中性粒细胞、血小板、白细胞均显著高于对照组,淋巴细胞水平显著降低,差异均有统计学意义(均P<0.05);轻度组患者中性粒细胞中未见或极少见毒性颗粒,中度组和重度组患者中性粒细胞中毒颗粒逐渐增大,核突积分和毒性指数也逐渐增大,差异均有统计学意义(均P<0.05);随着中毒程度的增加,患者中PLR和NLR逐渐升高,且显著高于对照组,差异具有统计学意义(P<0.05);Logistic回归分析显示,PLR和NLR均是早期CO中毒的独立危险因素(P<0.05)。结论:早期CO患者中毒严重程度与PLR和NLR密切相关,血小板、中性粒细胞和淋巴细胞等的检测和PLR、NLR有助于早期CO中毒患者的病情评估。
