Ribbon-like Cu doped V6O（13） was synthesized via a simple solvothermal approach followed by heat treatment in *** an cathode material for lithium ion battery,the ribbon-like Cu doped V6O（13 ）electrode exhibited good capacity retention with a reversible capacity of over 313 m Ah·g^-1 for up to 50 cycles at 0.1C,as well as a high charge capacity of 306 m Ah·g^-1 at a high current rate of 1 C,in comparison to undoped V6O（13 ）electrode（267 m Ah·g^-1 at 0.1C and 273 m Ah·g^-1 at 1 C）.The high rate capability and better cycleability of the doped electrode can be attributed to the influence of the Cu ions on the mophology and the electronic conductivity of V6O（13） during the lithiation and delithiation process.

The underlying causes of biodiversity disparities among geographic regions have long been a fundamental theme in ecology and ***,the patterns of phylogenetic diversity(PD) and phylogenetic beta diversity(PBD) of congeners that are disjunctly distributed between eastern Asia-eastern North America(EA-ENA disjuncts) and their associated factors remain *** we investigated the standardized effect size of PD(SES-PD),PBD,and potentially associated factors in 11natural mixed forest sites(five in EA and six in ENA) where abundant EA-ENA disjuncts *** found that the disjuncts in ENA possessed higher SES-PD than those in EA at the continental scale(1.96vs-1.12),even though the number of disjunct species in ENA is much lower than in EA(128 vs 263).SESPD of the EA-ENA disjuncts tended to decrease with increasing latitude in 11 *** latitudinal diversity gradient of SES-PD was stronger in EA sites than in ENA *** on the unweighted unique fraction metric(UniFrac) distance and the phylogenetic community dissimilarity,PBD showed that the two northern sites in EA were more similar to the six-site ENA group than to the remaining southern EA *** on the standardized effect size of mean pairwise distances(SES-MPD),nine of eleven studied sites showed a neutral community structure(-1.96 ≤SES-MPD ≤1.96).Both Pearson’s r and structural equation modeling suggested that SES-PD of the EA-ENA disjuncts was mostly associated with mean divergence ***,SES-PD of the EA-ENA disjuncts was positively correlated with temperaturerelated climatic factors,although negatively correlated with mean diversification rate and community *** applying approaches from phylogenetics and community ecology,our work sheds light on historical patterns of the EA-ENA disjunction and paves the way for further research.

目的:探讨四联疗法基础上加用益生菌治疗幽门螺杆菌(helicobacter pylori,Hp)阳性慢性萎缩性胃炎伴焦虑抑郁的疗效。方法:选取2016年1月至2018年1月重庆市急救医疗中心收治的Hp阳性慢性萎缩性胃炎伴焦虑抑郁患者132例,以随机数字表法分... 详细信息

目的:探讨四联疗法基础上加用益生菌治疗幽门螺杆菌(helicobacter pylori,Hp)阳性慢性萎缩性胃炎伴焦虑抑郁的疗效。方法:选取2016年1月至2018年1月重庆市急救医疗中心收治的Hp阳性慢性萎缩性胃炎伴焦虑抑郁患者132例,以随机数字表法分为观察组和对照组,每组66例。对照组患者给予四联疗法,观察组患者在对照组的基础上加用双歧杆菌乳杆菌三联活菌片治疗。比较两组患者的白细胞介素6(IL-6)、C反应蛋白(CRP)及肿瘤坏死因子α(TNF-α)含量,Hp根除率、汉密尔顿焦虑量表评分(hamilton anxiety scale,HAMA)、汉密尔顿抑郁量表(hamilton depression scale,HAMD)评分、临床疗效及不良反应发生情况的差异。结果:治疗后,观察组患者IL-6、CRP及TNF-α含量明显低于对照组,Hp根除率明显高于对照组,差异均有统计学意义(P<0.05);治疗后,观察组患者HAMA评分、HAMD评分明显低于对照组,差异均有统计学意义(P<0.05)。观察组患者的总有效率为96.97%(64/66),明显高于对照组的84.84%(56/66),差异有统计学意义(P<0.05)。观察组患者的不良反应发生率为18.18%(12/66),明显低于对照组的45.45%(30/66),差异有统计学意义(P<0.05)。结论:双歧杆菌乳杆菌三联活菌片辅助治疗Hp阳性慢性萎缩性胃炎的疗效确切,有助于Hp的清除,有利于改善焦虑抑郁等不良心理状态,且不良反应发生率低。
