目的：比较两种细胞株为底物间接免疫荧光法( indirect immunofluorescence assay,IIF)检测细胞膜DNA( cell membrane DNA,cmDNA)抗体在儿童系统性红斑狼疮( juvenile systemic lupus erythema-tosus,JSLE)中的检测效果。评价cmDNA抗体单独及与核小体抗体( anti-nucleosome antibody,AnuA)、史密斯( Smith,Sm)抗体和双链DNA( double-stranded DNA,dsDNA)抗体联合检测对JSLE的诊断价值；探讨cmDNA抗体与临床特点的相关性。方法选取92例JSLE为研究对象,71例非JSLE风湿病患儿为对照组。留血清采用IIF分别观察培养的人B细胞株Raji、人早幼粒白血病细胞株HL60细胞膜的荧光图形；同时用IIF检测抗核抗体( antinuclear antibody,ANA)；联合酶联免疫吸附法( enzyme-linked immuno sorbent assay,ELISA)和IIF检测dsDNA抗体；联合应用免疫双扩散法和免疫印迹法检测Sm抗体、ELISA法测定AnuA,收集同期临床资料。结果以两种细胞株为底物检测JSLE患儿血清cmDNA抗体,发现Raji细胞株较HL60细胞株更易复苏、荧光图形亮度更强,表达效果更好。 cmDNA抗体在JSLE组较对照组有更高的阳性率。以Raji细胞株为底物检测cmDNA抗体,cmDNA抗体的敏感性明显高于Sm抗体及dsDNA抗体(P0．05),但低于Sm抗体及AnuA(P<0．01)。 cmDNA抗体分别与dsDNA抗体、Sm抗体及AnuA联合检测在SLE诊断中的敏感性均明显高于单独检测( P<0．05)。cmDNA抗体与SLE疾病活动度评分无相关性( P=0．907)。结论 cmDNA抗体对儿童SLE诊断的敏感性高,特异性强,可能成为儿童SLE诊断的相对特异性抗体之一。 cmDNA抗体与dsDNA抗体、Sm抗体及AnuA联合检测可提高对儿童SLE诊断的敏感性。选择Raji细胞株为底物检测cmDNA抗体较HL60细胞株更有优势。

通过分光光度计测定腐蚀后溶液中钛离子浓度的方法,研究了钛在H2O2溶液中的腐蚀特性,以及不同pH值条件下,K+,Ca2+,Na+,Mg2+,Cl-,HPO42-,H2PO4-等添加离子对钛腐蚀的影响。结果表明:Ca2+对钛腐蚀具有最强的抑制性,而HPO42-则具有最强的促进作用。分析认为:Ca2+通过吸附到钛表面形成CaTiO3或者CaO2来抑制钛的腐蚀;而HPO42-则是吸附到钛表面来增加表面氧化膜的缺陷,从而促进钛的腐蚀。

This paper studied the allelopathic effects on the fungi and pest insests and the chemical compositions of the essential oil of ***×***. Our experimental results indicated that the leaf oil emulsion of ***×*** inhibited the growth of four fungi tested. As the concentration went higher, the inhibition also became stronger. When the concentration of leaf oil was at 1600μg/ml, the effect of inhibition on epiphytes was highest. The inhibition rate of four fungi such as Fusarium oxysporum, Pyriculerie grisea, Glorosprium musarum, Phytophthora capsici was 58.08% 、 79.24% 、 75.27% and 92.18% respectively。Also, the leaf oil of ***×*** inhibited the pupation and feeding behavior of the pest insects tested. The same concentration effect as in the fungi was observed. When the concentration of leaf oil was at 2500μg/ml, the inhibition rate of Spodoptera litura Fabricius and Helicoverpa armigera Hubner was highest, the anti-feeding rate was 56.26% and 86.6% respectively, while the pupation rate was 45.28% and 7.45% respectively. We analyze the leaf oil of ***×*** by GC/MS. The main components which per cent is higher 3% were identified such as : α-pinene(13.63 %)、Alloocimene(43.22%)、Gamma.-terpinene(5.49%)、2,6-Octadien-1-ol, 3,7-dimethyl-, (E)- ( 3.58 % )、 BETA. fenchyl alcohol ( 4.58 % )、 2-amino-3,5-dicyano-6-(4-methoxyphenoxy)-pyridine(3.67%). Most components identified are terpenes which have been classified as allelochemicals. It can be concluded that the ***×*** had certain allelopathic effects on the pest insects and fungi by measuring allelopathic effects and identifying allelochmicals. The allelopathic potentials of the leaf oil of ***×*** needs further research, especially with field-environment similar conditions.

The study determined the variation pattern of soil microorganisms, soil biological activity, soil enzyme activity and soil nutrient status in a Eucalyptus ABL12 plantation with different undergrowth during May, 2004 to Jan., 2005, located in Danzhou, western Hainan Province. The results indicated that, the soil microbial properties and soil nutrients of the Eucalyptus stand were lower than those of the controls, the vegetable field and rubber tree stand. The numbers of soil microorganisms, soil biological activity, soil enzyme activity and soil nutrients were recorded highest in vegetable field, followed at a decreasing order by rubber tree plantation, legume-intercropped plot, herbage-intercropped plot and monoculture plot. All the parameters measured showed a tendency of vertical variation, i.e., decrease with the increase of soil depth. Seasonal variation was also observed in the numbers of soil microorganism, soil biological activity and soil enzyme activity with a single peak curve pattern that occurred in September and October at large. Bacteria were found to be the most abundant, followed by actinomycetes and fungi. These results demonstrated that intercropping ***12 with tropical legumes has improved largely the soil environment for the soil microorganisms to live in, indicative of the better soil microbiological properties and soil nutrient levels.

Seldom could metals and alloys maintain excellent properties in cryogenic condition, such as the ductility, owing to the restrained dislocation ***, a face-centered-cubic(FCC) CoCrFeNi highentropy alloy(HEA) with great ductility is investigated under the cryogenic environment. The tensile strength of this alloy can reach a maximum at 1,251±10 MPa, and the strain to failure can stay at as large as 62% at the liquid helium temperature. We ascribe the high strength and ductility to the low stacking fault energy at extremely low temperatures,which facilitates the activation of deformation ***, the FCC→HCP(hexagonal close-packed) transition and serration lead to the sudden decline of ductility below 77 K. The dynamical modeling and analysis of serrations at 4.2 and 20 K verify the unstable state due to the FCC→HCP transition. The deformation twinning together with phase transformation at liquid helium temperature produces an adequate strain-hardening rate that sustains the stable plastic flow at high stresses, resulting in the serration feature.

为了明确引起四川省广汉市鱼腥草新型叶斑及茎斑类病害的病原菌种类,为该病的科学防治提供理论依据,对采自广汉市的鱼腥草病茎叶通过组织消毒分离、离体接种、形态学观察与基于核糖体转录间隔区(ITS)、延长因子(tef1)、钙调蛋白(cal)和组蛋白(his3)基因的分子鉴定进行病原菌的分离鉴定。结果表明,病原菌菌丝呈灰白色到浅褐色,其分生孢子器可产生纺锤形到椭圆形的α型分生孢子以及丝状或钩状β型分生孢子。多基因联合系统发育分析表明,病原菌在大豆间座壳(Diaporthe sojae)和菜豆间座壳(D. phaseolorum)分枝外单独聚为一枝,并且3枝一起聚为一个大枝,因此建议成立一个新种—鱼腥草间座壳(D. houttuynia)来容纳此类病菌。结合形态学和分子鉴定结果,将引起广汉市鱼腥草新型叶斑及茎斑类病害的病原菌鉴定为鱼腥草间座壳(D. houttuynia)。
