目的:探究肝硬化患者中发生血小板减少症(TCP)的相关因素。方法:该研究为横断面研究。纳入北京大学第一医院2010年1月1日至2020年12月31日初次诊断为肝硬化的住院患者,收集人口统计学特征、肝硬化病因、肝硬化并发症、实验室指标、Child-Pugh分级、有创操作、住院期间病死率等临床资料。用logistic回归模型探索肝硬化患者发生TCP的相关因素。分类变量以χ^(2)检验进行比较;连续变量的组间比较用t检验、单因素方差分析(ANOVA)或非参数检验。结果:共2592例肝硬化患者,排除临床资料不完整的75例,纳入2517例进行分析。其年龄为58(50,67)岁,男性占64%,1435例(57.0%)发生TCP,434例(17.2%)出现3~4级TCP。性别、原发性胆汁性胆管炎(PBC)、原发性硬化性胆管炎(PSC)、合并食管胃静脉曲张(EGV)为TCP的主要相关因素。女性(OR=1.32,95%CI:1.12~1.56,P=0.001)更易合并TCP。合并EGV(OR=3.09,95%CI:2.63~3.65,P<0.001)者更易发生TCP,这可能与其脾功能亢进并发比例更高有关(P<0.001);PBC(OR=0.64,95%CI:0.50~0.82,P<0.001)和PSC(OR=0.23,95%CI:0.06~0.65,P=0.010)患者更少发生TCP,这可能是由于PBC患者的凝血酶原时间更短、凝血功能更好(P<0.001),及PSC患者合并脾功能亢进的比例更低(P=0.004)。TCP及3~4级TCP患者止血操作率更高(P值均<0.05),肝活检率更低(P<0.05)。3~4级TCP患者院内病死率高于未发生3~4级TCP患者(P=0.004)。结论:肝硬化患者常见TCP,其中女性合并EGV患者TCP发生率较高,合并PBC和PSC者TCP发生率较低。TCP影响有创操作,且与不良结局相关。

Introduction: The severity of Sars-Cov-2 infection is associated with the development of acute respiratory distress syndrome (ARDS). The progression to ARDS appears to be driven by a major inflammatory mechanism potentially sensitive to corticosteroids. Observation: This article describes the case of an elderly patient was admitted to emergency departments for intense asthenia, accompanied by motor diarrhoea, dyspnoea with desaturation in ambient air, in a context of strong suspicion of infection linked to COVID-19. The article also reviews the existing literature on the diagnosis and treatment of this severe form of the disease. Conclusion: Corticosteroids, and in particular dexamethasone, have been shown to be effective in the management of patients with COVID-19, an oxygen-releasing disease.

脉冲激光沉积技术制备ba_(0.85)Ca_(0.15)Zr_(0.1)Ti_(0.9)O_(3)(BCZT)外延薄膜时通常需要较高的沉积温度,且易含有氧空位缺陷。本文旨在提供一种基于脉冲激光沉积技术接后退火处理工艺,并成功在导电基板上制备了高质量BCZT外延薄膜,探究了退火温度对BCZT外延薄膜结构和性能的影响。不同温度(750、800、850和900℃)退火后薄膜均呈现纯净物相,且随着退火温度的升高,薄膜的铁电性能逐渐提高,2Pr由4.2μC/cm^(2)提升至17.6μC/cm^(2),但900℃退火温度下薄膜样品的漏电流问题最严重。通过拟合J-E关系表明,低电场下700℃至850℃退火后的薄膜均遵循欧姆导电机制,而900℃退火后的薄膜遵循空间电荷限制电流机制,高电场下所有退火温度下的薄膜均遵循福勒-诺德海姆隧穿机制。

Journal of Integrative Plant Biology 2005年第2期47卷 214-222页

Reverse transcription-polymerase chain reaction (RT-PCR) was performed to isolate a cDNA clone using specific primers designed based on the barley (Hordeum vulgare L.) Mlo gene cDNA sequence.A full-length cDNA encoding an Mlo-like protein was isolated and characterized in a Triticum aestivum L.-Haynaldia villosa L. 6VS/6AL translocation line. The putative protein consists of 534 amino acid residues,which contain a nuclear localization motif (NLS), nine casein kinase Ⅱ motifs (S/T-X-X-D/E) and seven protein kinase C motifs (S/T-X-R/K). It is highly homologous to other plant Mlo proteins. Thus, this clone was designated as ta-Mlo (Genbank accession No. AF384144). Northern blotting analysis showed that the transcription of ta-Mlo was enhanced slightly by Blumeria graminis (DC) EO Speer f. sp. tritici. Western blotting analysis showed that the protein expression product of the ta-Mlo gene in wheat seedling leaves is a membrane-bound protein. The protein could be induced by B. graminis. Southern blotting analysis indicated that there is one copy of the ta-Mlo gene in each wheat genome. ta-Mlo was localized on specific chromosomal regions of 2AL, 2BL, and 2DL in wheat.
