围绝经期综合症治疗进展 总被引:1,自引:0,他引:1
女性一生中大约有1/3的时间是在绝经后度过的,围绝经期症状使得女性的日常生活及工作受到了很大的影响。传统的治疗方法为激素替代治疗,但因可能会增加乳癌和子宫内膜癌等的发病风险,其应用还存在很大的争议,非激素类药物包括中枢肾上腺素受体激动剂,选择性的5-HT重摄取抑制剂,Y-氨基丁酸类似物,黑升麻类药物等。黑升麻类药物缓解围绝经期症状的疗效是肯定的,黑升麻没有雌激素样作用,可能是通过5-羟色胺受体来发挥作用的。 相似文献

黑升麻是一种植物药,目前已广泛应用于缓解围绝经期综合征的相关症状。近些年来,大量临床研究证明,黑升麻能有效缓解低雌激素相关的血管舒缩症状(潮热出汗)、精神心理症状(失眠、抑郁、易激惹)、泌尿生殖症状(阴道萎缩、干涩)等,并能预防绝经后妇女的骨质疏松。与激素疗法相比,黑升麻的不良反应少且轻,暂未发现妇科恶性肿瘤增加的风险。其安全性远远高于激素,且对身体还有其它的潜在益处。黑升麻的作用机制目前还未明确,目前发现黑升麻的作用机制类似于雌激素受体调节剂,且黑升麻还与神经递质5-羟色胺、γ-氨基丁酸及阿片受体有关。本文主要综述黑升麻在缓解围绝经期综合征中的作用机制、有效性及安全性,并与其它治疗围绝经期综合征的药物的疗效进行比较。 相似文献

激素印迹是单细胞动物和多细胞动物的一种生理现象,也是选择参与信号识别过程分子的工具。激素印迹后,受体记忆将遗传给子孙后代,因此其对进化的作用可能是很大的。同时,激素印迹还有利于物种的维持。另外,激素印迹过程还是具有终身效应的临时开放系统的一部分。没有印迹,就没有完全的受体成熟,而不成熟的受体是不能和适量的激素结合的。在围 期诸如治疗药物和环境污染剂等人工合成的物质分子易致错误或病理印迹。许多研究表明错误印迹对生物体具有重要的影响。当然,单细胞动物的激素印迹过程与多细胞动物并不完全一样。 相似文献

绝经综合征是指女性绝经前后因雌激素水平波动或下降所引起的一系列生理及心理的短期、中期和长期的临床症状,严重影响老年女性的生活质量。目前激素替代治疗(HRT)被认为是治疗绝经综合征最有效的方法。但是,由于HRT相关的健康风险以及人群对HRT的担忧,很多女性不能或者不选择HRT治疗。因此,随着全球老龄化社会的到来,以绝经期女性为中心的综合治疗,包括共同决策替代药物成为当务之急。本文旨在阐述肠道菌群与绝经综合征临床症状的关系并分析治疗效果,探讨肠道菌群在绝经综合征治疗中的研究前景。

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
