Effect of glycerin on immediate cutaneous reactions of histamine (positive) and phosphate‐buffered saline (negative) controls in intradermal skin testing of healthy dogs: A randomised, blinded study

open access: yesVeterinary Dermatology, Volume 34, Issue 4, Page 348-354, August 2023., 2023
Background – Glycerinated allergen extracts contain 50% glycerin, an excellent preservative. While glycerin is a recognised irritant in humans, the utility of glycerinated extracts for intradermal testing has not been validated in dogs. Hypothesis/Objective – To determine and compare the effects of glycerin on immediate cutaneous reactions to ...

Functional trait dissimilarity drives arboreal ant community assembly while competitive trait hierarchies shape colony performance in experimental mesocosms

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3487-3503, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many broad‐scale studies along spatial and habitat gradients show that organisms' traits can strongly influence community assembly by facilitating dispersal and environmental filtering.

Effect of aspirin on maternal hemodynamics in Chinese women at high risk for preterm pre‐eclampsia: longitudinal study

open access: yesUltrasound in Obstetrics &Gynecology, Volume 66, Issue 5, Page 621-630, November 2025.
ABSTRACT Objectives To compare the maternal hemodynamics of Chinese women at low and at high risk for preterm pre‐eclampsia (PE) and assess the differences in hemodynamic parameters between high‐risk women with or without prophylactic aspirin. Methods This was a prospective longitudinal case–control study of 857 Chinese women with a singleton pregnancy

胸水细胞p53和K-ras基因突变对于肺癌的诊断价值

open access: yesZhongguo shiyan zhenduanxue, 2006
目的目的:研究p53和Kras基因在良恶性胸水细胞中的突变情况。方法研究组为34例伴有恶性胸水的肺癌患者,对照组为28例出现胸水的结核性胸膜炎和其他炎性胸膜炎患者。常规抽水胸水,提取胸水细胞DNA,采用PCRSSCP方法,分别对p53基因第7、8外显子和Kras基因第1、2外显子进行突变分析。结果研究组p53基因突变率为41.2%,而对照组只有7.1%,明显低于肺癌患者 ...

多变量Logistic回归分析在渗出性胸水病因鉴别诊断中的作用

open access: yesZhongguo shiyan zhenduanxue, 2008
目的利用多变量Logistic回归,综合分析多个临床常规检查结果,探索诊断渗出性胸水良、恶性质的简便方法。方法收集首次就诊时发现渗出性胸水的236例病例资料,对可能有助于诊断的性别、年龄、有无发热、有无异常包块、有无5年以上吸烟史以及胸水中CEA水平等6个指标分别进行单变量分析和多变量Logistic回归分析。结果单变量分析显示年龄、异常包块、吸烟史和胸水CEA具有统计学差别,但诊断价值有限。多变量Logistic回归分析显示性别、年龄、吸烟史、异常包块和胸水CEA水平是恶性胸水的预测指标 ...

基于常规实验室检查的良恶性胸/腹水鉴别诊断模型研究

open access: yesZhongguo shiyan zhenduanxue, 2010
目的分析常规实验室检查结果对胸/腹水良恶性质的鉴别诊断价值,并建立简便的数学诊断模型。方法查阅胸/腹水患者的病案资料,核实病因诊断,收集血细胞分析、血生化检查、胸/腹水常规及生化检查、血清肿瘤标志物检测结果等。单因素Logistic回归分析各项检查单项对良恶性胸/腹水的鉴别诊断价值,多因素Logistic回归分析建立数学诊断模型,并评价其对恶性胸/腹水的诊断价值。结果常规实验检查的27项单项指标中有13项对胸/腹水性质有鉴别诊断价值(P=0.000-0.018)。血白细胞计数、血总胆红素、胸 ...

ADA、CEA及GLU在癌性及结核性胸腔积液性质诊断的临床应用价值

open access: yesZhongguo shiyan zhenduanxue, 2015
目的研究胸水腺苷酸脱氨酶(ADA)、癌胚抗原(CEA)以及葡萄糖(GLU)的检测对癌性及结核性胸水性质的鉴别价值。方法 158例癌性胸腔积液设为癌性组,135例结核性胸腔积液设为结核组,观察两组胸水ADA、CEA及GLU变化情况,并运用ROC曲线对三指标对癌性胸腔积液及结核性胸腔积液的诊断进行评价。结果癌性组与结核组胸水ADA、CEA及GLU统计学差异均有显著性 ...

几种不同检测方法对结核性胸膜炎诊断价值分析

open access: yesZhongguo shiyan zhenduanxue, 2009
目的探讨几种不同检测方法对结核性胸膜炎诊断价值。方法检测47例胸腔积液患者,其中37例经组织病理学或病原学明确诊断的结核性胸膜炎,10例诊断为恶性胸水。检测全部患者胸水中ADA活性、抗结核分枝杆菌抗体、结核分支杆菌特异性ELISPOT检测,经统计学处理后,评价各项指标对结核性胸膜炎诊断的灵敏度、特异度及临床诊断符合率。结果结核性胸水中腺苷脱氨酶(ADA)活性、结核分枝杆菌抗体,结核分支杆菌特异性ELISPOT检测,与恶性胸水组比较差别有统计学意义 ...
