According to content of the Selaginella sinensis, a special species of Chinese plants, was closely correspond with the human activities reflecting by the historical and archeological data in the area, its content among the pollen is regarded as a proxy for interpreting extent of human activities.

利用孢粉分析中的中华卷柏这个中国植物特有种在孢粉含量中的变化与研究区历史、考古资料反映的人类活动具有十分密切的对应关系，将中华卷柏孢子在孢粉组合中含量变化作为诠释人类活动的因子。

Selaginella extract was given for 26 weeks,ALP,TRAP,BGP,TNF-αlevel of drug group A were significantly lower than the model(P.01);E_2,CT level in drug groups increased significantly(P.01),group A and group D were the most obviously.Dosage in group D was only 1/4 of the dosage level in group A.

给予卷柏提取物26周，卷柏用药A组ALP、TRAP、BGP、TNF-α水平比模型组明显降低(P.01)；卷柏各用药组中，E_2、CT水平明显升高(P.01)，A组和D组作用比较明显，且D组用药量明显低于A组，是A组用药量的1/4。

Selaginellales An order of the Lycophyta containing the single living genus Selaginella, sometimes called spike-mosses, with about 700 species, found worldwide, but especially in the tropics.

卷柏目：为石松亚门下一目，该目仅有单属卷柏属，常被称为卷柏。这类植物有700多种，分布广泛，以热带居多。

The experimental study of estrogenic activities of five kinds of Chinese herbal medicines Use uterus growth test and reporter gene technique to study the estrogenic activity of Selaginella tamariscina, Pinus massoniana Lamb, Corallodiscus flabellate, Dryopteris sublaeta Ching et Hsu and Leonurus heterophyllus Sweet.

卷柏等5种中药植物雌激素活性筛选的实验研究采用小鼠子宫增重实验结合荧光素酶报告基因技术，对卷柏、松针、益母草、石胆草及贯众等五种中药进行了植物雌激素活性的研究。

Families, 62 genus and 107 species of Pteridophyte resources have been found in Meihuashan mountain, west of Fujian province, which include more than 5 species of resources like Selaginellaceae, Pteridaceae, Athyriaceae, Aspleniaceae, Thelypteridaceae, Dryopteridaceae and Polypodiaceae and over 4 genus of plants like Selaginella, Plagiogyria, Pteris, Asplenium, Cyclosorus and Arachniodes as well as Cibotium barometz, the second state specially-protected Pteridophyte.

福建省闽西梅花山共有蕨类植物30科62属107种，种数5种以上的科有卷柏科、凤尾蕨科、蹄盖蕨科、铁角蕨科、金星蕨科、鳞毛蕨科、水龙骨科；种数4种以上的属有卷柏属、瘤足蕨属、凤尾蕨属、铁角蕨属、毛蕨属、复叶耳蕨属，其中包括国家二级重点保护蕨类金毛狗。

The representative families are Dryopteridaceae, Athyriaceae, Polypodiaceae, Thelypteridaceae, Selaginellaceae and Aspleniaceae. The main genera are Dryopteris, Selaginella, Asplenium, Arachniodes, Pteris, Allantodia and Plagiogyria. The top families' distribution types are cosmopolitan and pantropic ones, the main genera are pantropical ones, while species distribution type belong to the east Asia type and represents the feature of subtropics transition to warm temperated areatype. As for the order of closeness, the sequence of pteridophytes floristic relations between Songyang and the adjacent regions goes as Southwest China, South China, Central China, Japan, North China, Northwest China and Northeast China. The six upland pteridophytes next to Songyang can be put into the same natural flora because of its closest relationship. But compared with other 11 upland fern flora in China, fern in Songyang is not rich enough. There are 37 species endemic to China in Songyang.

结果表明，松阳蕨类植物共有38科72属161种7变种；优势科为鳞毛蕨科、蹄盖蕨科、水龙骨科、金星蕨科、卷柏科、铁角蕨科，优势属为鳞毛蕨属、卷柏属、铁角蕨属、复叶耳蕨属、凤尾蕨属、短肠蕨属、瘤足蕨属；科的分布以世界分布和泛热带分布为主，属的分布以泛热带分布为最多，种以东亚分布类型为主，特别是中国—日本分布类型最多，表现出亚热带向暖温带过渡的特点；本区与邻近地区蕨类植物区系关系的密切程度由大到小依次为西南、华南、华中、日本、华北、西北、东北；与邻近的6个山地蕨类植物区系的亲缘关系密切，可以划为同一自然区；与国内11山地蕨类植物区系相比，松阳的蕨类植物丰富程度不高；松阳拥有37种中国特有蕨类植物及一些珍稀蕨类植物，有较高的保护价值。

Nonetheless, the result showed that Pinus, Ginkgo, Cycas form a monophyletic group, which is sistered to angiosperms. Together, they from a clade that is sistered to Gnetales.

邻近连接法和贝叶氏导出氏分析结果将松叶蕨、瓶尔小草，和生根卷柏的matK序列一起形成一个单源群，同属石松类的过山龙与生根卷柏序列并未形成姐妹群。

We found a clear trnK5'-matK-trnK3' structure in Ophioglossum petiolatum, Lycopodiella cernua and Selaginella doederleinii. PCR with degenerate primers failed to amplify any trnK or matK fragments from other ferns or allies. However, dot blot hybridization showed distinct signals in these plant failed to amplify matK fragments.

本论文鉴定原始陆生植物其他未被检视的重要类群中叶绿体matK基因的存在，结果发现瓶尔小草、过山龙、生根卷柏都有trnK5'-matK-trnK3'的结构，以RT-PCR侦测matK表现时，瓶尔小草和过山龙都有侦测到讯号，但生根卷柏却没有，显示matK的表现在原始陆生植物似乎不是那麼一致。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
