血脂及血液流变学指标与突发性聋患者听力曲线类型的关系及其临床疗效的影响因素分析

摘要 目的：探究血脂及血液流变学指标与突发性聋（SSHL）患者听力曲线类型的关系,并分析临床疗效的影响因素。方法：选取2020年6月-2022年1月我院收治的103例SSHL患者设为SSHL组,另选取103例体检健康者设为健康组,分析两组血脂水平及血液流变学指标,比较不同听力曲线类型的SSHL患者血脂水平及血液流变学指标,Spearman相关分析血脂水平及血液流变学指标与SSHL患者听力曲线类型的关系,单因素和多因素Logistic回归模型分析SSHL患者临床疗效的影响因素。结果：与健康组比较,SSHL组总胆固醇（TC）、三酰甘油（TG）与全血高切、中切、低切粘度及血浆粘度明显增高（P＜0.05）,高密度脂蛋白-C（HDL-C）、低密度脂蛋白-C（LDL-C）差异比较无统计学意义（P＞0.05）。不同听力曲线类型的SSHL患者各项血脂指标比较差异均无统计学意义（P＞0.05）,不同听力曲线类型的SSHL患者各项血液流变学指标比较差异均有统计学意义（P＜0.05）,其中全聋型患者各项血液流变学指标显著高于低频下降型患者（P＜0.05）。血脂四项与SSHL听力曲线类型无显著相关性（P＞0.05）,而血液流变学指标与SSHL听力曲线类型显著相关（P<0.05）。治疗无效组患者双耳患病比例、听力曲线类型为全聋型比例、全血高切粘度、全血低切粘度、血浆粘度显著高于有效组患者（P＜0.05）,多因素Logistic分析结果显示：双耳患病、听力曲线类型为全聋型、血浆粘度增加为SSHL患者治疗无效的危险因素（P＜0.05）。结论：SSHL患者存在血脂及血液流变学异常,血液流变学与SSHL患者听力曲线类型和临床疗效有一定关系,其中双耳患病、全聋型、血浆粘度增加为SSHL患者治疗无效的危险因素,检测血脂和血液流变学对于SSHL诊治具有一定临床指导意义。

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.
