清消法对痤疮患者面部皮肤微生态的调节作用

通过观察皮肤酸碱度、皮脂分泌率、皮损部细菌密度、多样性和局部IL-1、IL-6水平,探讨清消法对寻常型痤疮患者面部微生态的影响。

选择我院收治的寻常型痤疮患者142例,按照随机数字表分成治疗组和对照组,各71例。对照组患者口服异维A酸联合外涂阿达帕林凝胶、夫西地酸乳膏;治疗组患者采用清消法联合外涂阿达帕林凝胶、夫西地酸乳膏进行治疗。观察两组患者的临床疗效、痤疮综合分级系统（GAGS）评分、面部皮肤酸碱度、皮脂分泌率、皮损部细菌密度和多样性及皮损局部IL-1、IL-6水平。

治疗组患者的总有效率（92.96%）高于对照组（81.69%）。与对照组比较,治疗组患者GAGS评分、皮肤酸碱度、皮脂分泌率、皮损部细菌密度及IL-1、IL-6水平均显著降低（均P＜0.05）。

清消法可通过调节面部油脂分泌和酸碱度,改善患者皮损部菌群失衡,降低炎症因子,从而有效治疗痤疮。

     

寻常痤疮中的微生态机制研究

最近的一项研究发现健康人群和寻常痤疮患者面部及肠道的菌群存在显著差异,寻常痤疮患者面部及肠道菌群出现紊乱,并且发现寻常痤疮并不与痤疮丙酸杆菌的过度增殖有关,而是取决于菌株的类型及其之间的平衡。此外,肠道菌群的紊乱也会间接影响寻常痤疮的发生和发展。因此,越来越多的研究致力于改善寻常痤疮患者面部和肠道的菌群平衡,进而达到治疗寻常痤疮的目的。本文主要综述了寻常痤疮患者面部和肠道的菌群失衡与寻常痤疮发病的关系,以及改善寻常痤疮患者面部和肠道菌群失衡的益生菌疗法。

Recent advances in the study of Kaposi's sarcoma-associated herpesvirus replication and pathogenesis

It has now been over twenty years since a novel herpesviral genome was identified in Kaposi's sarcoma biopsies. Since then, the cumulative research effort by molecular biologists, virologists, clinicians, and epidemiologists alike has led to the extensive characterization of this tumor virus, Kaposi's sarcoma-associated herpesvirus(KSHV; also known as human herpesvirus 8(HHV-8)), and its associated diseases. Here we review the current knowledge of KSHV biology and pathogenesis, with a particular emphasis on new and exciting advances in the field of epigenetics. We also discuss the development and practicality of various cell culture and animal model systems to study KSHV replication and pathogenesis.     

The structure, reproduction and taxonomy of Vidalia and Osmundaria (Rhodophyta, Rhodomelaceae)

Comprises species occurring mostly in subtidal habitats in tropical, subtropical and warm-temperate areas of the world. An analysis of the type species, V. spiralis (Sonder) Lamouroux ex J. Agardh, a species from Australia, establishes basic characters for distinguishing species in the genus. These characters are (1) branching patterns of thalli, (2) flat blades that may be spiralled on their axis, (3) width of the blade, (4) primary or secondary derivation of sterile and fertile branchlets and (5) position of sterile and fertile branchlets on the thalli. Application of the latter two characters provides an important basic method for separation of species into three major groups. Osmundaria , a genus known only in southern Australia, was studied in relation to Vidalia , and its separation from the Vidalia assemblage is not accepted. Species of Vidalia therefore are transferred to the older genus name, Osmundaria. Two new species, Osmundaria papenfussii and Osmundaria oliveae are described from Natal. Confusion in the usage of the epithet, Vidalia fimbriala Brown ex Turner has been clarified, and Vidalia gregaria Falkenberg, described as an epiphyte on Osmundaria pro/ifera Lamouroux, is revealed to be young branches of the host, Osmundaria prolifera.     

New or rare chromosome counts in Artemisia L. (Asteraceae, Anthemideae) and related genera from Kazakhstan

Fifteen chromosome counts of six Artemisia taxa and one species of each of the genera Brachanthemum, Hippolytia, Kaschgaria, Lepidolopsis and Turaniphytum are reported from Kazakhstan. Three of them are new reports, two are not consistent with previous counts and the remainder are confirmations of very scarce (one to four) earlier records. All the populations studied have the same basic chromosome number, x = 9, with ploidy levels ranging from 2x to 6x. Some correlations between ploidy level, morphological characters and distribution are noted.

Selection with two alleles and complete dominance

For a plant selection model with frequency-independent viabilities, fertilities and selfing rates, it is shown that apart from global fixation, for certain parameter combinations a protected polymorphism and facultative fixation (either allele may become fixed according to initial frequencies) may both occur. Facultative fixation requires different selling rates for the dominant and recessive type. Protection of the polymorphism requires resource allocation for male and female function. In this connection the problem of purely genetically caused population extinction is discussed.
For general frequency dependence and regular segregation, the chances for establishment of a completely recessive gene are compared to those of a completely dominant gene. It is proven that the process of establishment of the recessive gene, despite a fitness advantage, may be considerably endangered by drift effects if random mating prevails. The recessive gene may reach the same effectivity in establishment as a dominant gene, only if the recessive homozygote mates exclusively with its own type during the period of establishment.
