目的:探究透脓托毒饮配合西医手术疗法对肛周坏死性筋膜炎(Perianal necrotizing fasciitis,PNF)患者预后的影响。方法:选择西安市中医医院肛肠科于2013年10月-2018年10月收治的肛周坏死性筋膜炎患者60例,根据其入院顺序经随机数字表法分为两组,每组各30例。其中,对照组行PNF清创术,研究组在对照组基础上辅助透脓托毒饮进行治疗,对比两组的治疗总有效率、外周血炎症因子水平、住院时间、创面愈合时间、疼痛积分、腐肉脱落时间、复发率和死亡率。结果:治疗后,研究组的总有效率显著高于对照组(93.3%vs. 73.3%,P0.05);两组血清肿瘤坏死因子-α(Tumor necrosis factor-alpha, TNF-α)、白细胞介素-6(Interleukin-6, IL-6)、白细胞介素-10(IL-10)水平均较治疗前显著降低,且研究组以上指标均明显低于对照组(P0.05)。研究组的住院时间、创面愈合时间、疼痛积分、腐肉脱落时间均显著短于(低于)对照组(P0.05)。随访3个月,两组的术后复发率和死亡率比较均无显著差异(P0.05)。结论:透脓托毒饮配合清创术治疗PNF的效果显著优于单用清创术,其可有效改善患者的临床症状和预后,可能与其显著降低血清炎症因子水平有关。 相似文献

目的对妇产科手术切口护理效果分析。方法选择我院于2014年6月至2015年7月收收治的妇产科手术患者140例作为研究对象,对其随机分为实验组和对照组,每组有70例,对照组患者接受常规护理,实验组患者除了接受常规护理外,还接受围术期全面性的护理。并对两组手术患者的护理效果进行对比。结果对两组手术患者实施护理手段后,发现实验者患者在切口愈合、切口感染、切口脂肪液化和切口开裂等方面,都比对照组要占有优势,两组护理效果差异具有统计学意义(P0.05)。结论对妇产科手术患者实施围术期全面性护理,有效降低了患者的切口感染率,改善了患者的生活质量,值得推广和应用。 相似文献

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
