为了获得更多高效降解有机磷阻燃剂(OPFRs)的菌种资源,探明OPFRs微生物降解途径和作用机制,本研究以一株从广州某污水处理厂剩余污泥中筛选获得的对多种典型OPFRs具有降解能力的太平洋芽孢杆菌(Bacillus pacificus)为研究材料,选取环境中检出率高的磷酸三(2-氯乙基)酯(TCEP)、磷酸三(2-氯丙基)酯(TCPP)、磷酸三甲苯酯(TCP)、磷酸三苯酯(TPhP)作为OPFRs典型代表污染物,开展OPFRs混合污染物微生物降解研究.结果表明:Bacillus pacificus能以4种OPFRs(TCEP、TCPP、TCP、TPhP)作为磷源生长代谢.在投菌量为1.0g/L,污染物初始浓度为1.0mg/L时,Bacillus pacificus对TCP的降解效果显著,在第9d的降解率达96.1%,另外3种OPFRs的降解率为23%~34%.4种OPFRs的主要降解途径均是通过磷酯键断裂,最终生成氯乙醇、氯丙醇、磷酸和苯类等小分子化合物.其中,TCEP和TCPP还可以通过末端脱氯进行分解,生成磷酸三丙酯和磷酸三(2-乙基丙基)酯,而TCP则还可以通过甲氧基化而被分解为磷酸三甲酯.研究表明:Bacillus pacificus能耐受并有效降解4种常见的OPFRs混合污染物,可为环境OPFRs污染治理提供新思路和优质的微生物菌种资源.

Background There was a causal relationship between elevated lipoprotein(a)[Lp(a)]levels and increased risk of calcific aortic valve stenosis(CAVS)in whites and *** present study aimed to investigate whether Lp(a)levels were associated with aortic stenosis(AS)severity and clinical events in Chinese *** Levels of serum Lp(a)were measured in 652 patients with CAVS,whom all underwent baseline echocardiographic *** clinical endpoint was defined as a composite of aortic valve replacement(AVR)and cardiac *** Patients in the tertile 3 of Lp(a)had a higher percentage of severe AS compared with those in the tertile 1 and 2 of Lp(a)(46.2%vs.33.9%,P=0.005).Moreover,the top tertile of Lp(a)was an independent predictor of severe AS(OR=1.78,95%CI:1.18-2.66,P=0.006).However,there was no significant association between tertile 3 of Lp(a)and clinical events(hazard ratio:0.73;95%CI:0.43-1.24;P=0.239)in the multivariate Cox regression analysis during a mean follow-up time of 3.16±2.74 *** Elevated Lp(a)level was an independent predictor of severe AS by echocardiography in the Chinese population,but was not associated with the increased risk of AVR and cardiac death,suggesting that Lp(a)levels might be helpful in the risk stratification of patients with CAVS.

为探讨不同密度单粒精播对花生开花动态及结实特性的影响,以普通大花生品种花育25为材料,在行距相同的条件下设置4个处理,包括单粒播分别为株距9 cm、12 cm和15 cm,折合播种密度分别为27.8万株·hm^(-2)(S9)、20.8万株·hm^(-2)(S12)和16.7万株hm-2(S15)3个处理,和双粒播27.8万株·hm^(-2)(D18,穴距18 cm)1个处理,研究不同密度单粒精播对花生开花习性、果针形成、荚果发育动态、结实范围及产量的影响。结果表明,与双粒播相比,不同密度单粒播均可不同程度地促进花生早开花、多开花,增加有效果针数,促进荚果发育,低密度条件下,效果最为显著;从群体指标看,20.8万株·hm^(-2)的单粒精播模式下,花生开花数、有效果针数、结果数最多,荚果体积最大,荚果饱满度高,产量水平最高。不同密度单粒精播改变了花生的结实范围和荚果空间分布,密度降低,结实范围增加,但不同处理荚果干重(95%以上)仍主要分布在半径6.0 cm以内的空间范围内,密度20.8万株·hm^(-2)(株距12.0 cm)的单粒精播条件下,结实范围与半株距接近,更有利于群体间荚果的均匀分布。

Blast disease caused by the fungus Magnaporthe grisea results in significant yield losses of cereal crops across the *** date,very few regulatory genes contributing to blast resistance in grass species have been identified and the genetic basis of blast resistance in cereals remains ***,a core collection of foxtail millet(Setaria italica)containing 888 accessions was evaluated through inoculation with the blast strain HN-1 and a genome-wide association study(GWAS)was performed to detect regulators responsible for blast disease resistance in foxtail *** phenotypic variation of foxtail millet accessions inoculated with the blast strain HN-1 indicated that less than 1.60% of the samples were highly resistant,35.25% were moderately resistant,57.09% were moderately susceptible,and 6.08% were highly *** geographical pattern of blast-resistant samples revealed that a high proportion of resistant accessions were located in lower latitude regions where the foxtail millet growing season has higher rain *** 720000 SNP markers covering the Setaria genome,GWAS showed that two genomic loci from chromosomes 2 and 9 were significantly associated with blast disease resistance in foxtail ***,eight putative genes were identified using rice blast-related transcriptomic *** results of this work lay a foundation for the foxtail millet blast resistance biology and provide guidance for breeding practices in this promising crop species and other cereals.

对新形势下如何加快政府渔业管理职能转变进行了探讨。市场经济体制下我国政府渔业管理职能主要为渔业法制建设、宏观调节、公共服务和监督管理;目前的主要问题是渔业法律制度建设滞后、渔业经济宏观调控与微观管理转化不足、渔业公共服务薄弱、渔业监督执法不到位。关于加快政府渔业管理职能转变,文章建议:(1)优化渔业管理决策机制;(2)推进渔民和社会中介参与渔业管理;(3)改革渔业管理行政体制;(4)加强渔业行政服务;(5)合理划分政府部门涉及渔业的行政管理职能。

目的探讨常规听力学检查中婴儿中耳炎诊断相关的的敏感因素。方法研究对象为听力筛查未通过的婴儿48例（96耳），男31例，女17例；年龄1．5—12个月（平均4．3个月）。所有受试者均接受了颞骨CT薄层扫描和常规听力学测试。听力学检查包括气导和骨导听性脑干反应（ABR）、40Hz-听觉相关电位（40Hz-auditory event related potential，40Hz—AERP）、畸变产物耳声发射（DPOAE）、声反射及226Hz、1000Hz探测音鼓室声导抗。统计软件采用SPSS14．0标准统计软件包。以颞骨CT结果作为诊断的依据，与以下9项因素进行Kappa一致性检验、单因素Х^2检验和多因素Logistic回归分析。分析因素包括：226Hz及1000Hz探测音鼓室声导抗、ABR气导反应阈值、ABR骨气导反应阈值差值、ABRI波潜伏期、ABRⅠ～Ⅴ波间期、40Hz-AERP反应阈值、DPOAE反应幅值及声反射阈值。结果96耳中，CT确诊中耳炎77耳，中耳正常19耳。以颞骨CT扫描结果作为金标准，Kappa一致性检验表明，1000Hz鼓室声导抗测试、ABR气导反应阈值、ABRI波潜伏期、40Hz—AERP反应阈值和DPOAE与颞骨CT具有较好一致性（Kappa值均〉0．04，P值均〈0．001）。单因素分析提示，有7个因素与婴儿中耳功能有关（P值均〈0．001）：1000Hz探测音鼓室声导抗、声反射阈值、ABR气导反应阈值、ABR气骨导反应阈值差值、ABRI波潜伏期、40Hz—AERP反应阈值和DPOAE。Logistic回归分析显示，1000Hz探测音鼓室声导抗（P〈0．001）和40Hz—AERP反应阈值（P=0．004）可以列入Logistic回归方程。结论1000Hz鼓室声导抗可作为婴儿中耳炎检出的敏感因素，ABR气导反应阈值、ABRI波潜伏期、40Hz-AERP反应阈值和DPOAE可较好地反映婴儿的中耳功能。

【目的】谷瘟病是谷子生产中的重要病害,确定谷瘟病菌不同生理小种对谷子抗病资源鉴定、抗病品种培育和生产上不同抗病品种的合理配置有重要意义。构建谷瘟病小种鉴别的谷子品种体系,为鉴别不同谷瘟病生理小种奠定基础。【方法】用采集自不同谷子产区的10份谷瘟病菌对苗期谷子核心种质资源的60份代表品种进行接种鉴定,分别对不同菌株进行致病性和谷子品种抗、感敏感性判定,按照谷子谷瘟病0—9级法划分标准进行划分,将不同的抗性结果分别记录为高抗、抗病、中抗、感病和高感5个抗病水平,其中,高抗、抗病和中抗记作0,感病和高感记作1,将抗感性结果转化为0/1数据,用NTSYS软件构建进化树,根据品种的抗感性分类,选择最少的品种数量构建谷瘟病小种鉴定的标准品种体系。【结果】根据谷子资源对接种病菌的抗感反应差异,用NTSYS软件开展谷瘟病菌致病性聚类分析,以相似系数0.70为界,将10个谷瘟病菌株分为3类,将供试品种对10个谷瘟病菌株的抗感反应数据同样用NTSYS软件进行聚类分析,以相似系数0.65为界,将谷子品种资源划分为5类,并筛选出单皮粘、金屏谷子、锦谷5号、大毛毛谷、龙爪谷、假金苗和牛头谷等7个品种作为谷瘟病小种鉴别品种体系。同时筛选出黄棒头、齐头黄、单皮粘、白谷、维子那谷和郑谷4号等6个抗广谱菌株的品种,可以作为谷子抗病育种的抗性基因来源。【结论】建立了一套谷瘟病生理小种鉴别的品种体系,并为谷子抗谷瘟病育种筛选出多份广谱抗性基础材料。
