对高效液相色谱串联质谱法(HPLC⁃MS/MS)测定水产品中5种卡因类(cacaines)麻醉剂及其代谢物残留量的不确定度进行评定。
建立不确定度评定的数学模型,分析影响测定结果的各不确定度来源,并对各分量加以量化和合成,探讨各不确定度分量对测定结果的影响。
分析评定不确定度各分量,结果表明不确定度贡献主要来自标准曲线拟合、样品溶液制备、样品加标回收率、标准溶液配制和测量的重复性。当河虾中3⁃氨基苯甲酸乙酯甲基磺酸盐(MS⁃222)含量为8.68 μg‧kg-1时,其扩展不确定度为1.18 μg‧kg-1(
该方法适用于HPLC⁃MS/MS测定卡因类麻醉剂及其代谢残留量的不确定度分析,可为水产品中卡因类麻醉剂及其代谢测量结果的准确性提供科学可靠的依据。

目的 应用鼓膜切开法和鼓室接种细菌法构建鼓室硬化动物模型,观察两种方法造模后其鼓膜和鼓室粘膜的组织形态学变化.方法 40只SD大鼠分为4组,每组10只:A1组双耳鼓膜不作处理,作为正常对照;A2组双耳鼓膜紧张部后下象限作2 mm的切口;B1组双侧鼓室不作处理,作为正常对照;B2组双侧鼓室接种1×108 CFU/ml肺炎链球菌0.1 ml.分别于鼓膜切开后第2周及鼓室接种肺炎链球菌后第1、2、4、6、8周时观察各组大鼠鼓膜情况,比较鼓室硬化发生率;分别于造模后第2周和第8周取材行听泡连续切片HE染色,观察鼓膜及鼓室粘膜的组织形态学变化.结果 A2组14耳发生鼓膜钙化(14/20,70%);B2组死亡一只,6耳发生鼓膜钙化(6/18,33.33%),两组的鼓膜及鼓室粘膜均可观察到炎症细胞浸润及纤维组织增生,但B2组的改变更显著.两对照组(A1和B1组)既未发生鼓膜钙化,也未出现组织形态学改变.结论 两种鼓室硬化造模方法均切实可行,但鼓膜切开法操作更简单,成模周期更短,成模率更高. 相似文献

Primary pulmonary leiomyosarcoma (LMS) is a very unusual tumor.Although LMS has well-known metastatic potential,cutaneous metastasis is a remarkably uncommon.Exposure to cytotoxic agents could lead to "therapy-related myeloid neoplasm" (t-MN).Starting from 2008,the World Health Organization (WHO) has adopted the term to cover the spectrum of malignant diseases previously known as therapy-related acute myeloid leukemia (t-AML),therapy-related myelodysplastic syndrome (t-MDS) and therapy-related myelodysplastic/myelo-proliferative neoplasm (t-MDS/MPN).We described the onset of t-MDS and progression to t-AML in one case diagnosed as primary pulmonary LMS with cutaneous metastasis.This patient achieved complete remission (CR) after three courses of IA regimen chemotherapy (idarubicin 5 mg/d,d 1-3;cytarabine 100 mg/d,d 1-5) and 1 course of HA chemotherapy regimen (homoharringtonine 3 mg/d,d 1-3;cytarabine 100 mg/d,d 1-7).This case presents the natural course of therapy-related neoplasm and provides therapeutic experience for t-AML. 相似文献

Background:Hypertension (HTN) has been considered as a health concern in developing countries. And Hui is a minority group with a large population in China. Its genetic background, inadequate access to health services, eating habits, religious belief, ethnic customs, and other factors differ from that of other ethnic groups, which may influence the prevalence of HTN. However, there is no current meta-analysis on the prevalence and risk factors of HTN among Hui population. Thus we conducted a systematic review aiming to estimate the pooled prevalence and risk factors of HTN among Hui population.Methods:PubMed, The Cochrane library, Web of science, CINAHL Complete, Weipu Database (VIP), China Knowledge Resource Integrated Database (CNKI), Wanfang Database, and SinoMed were systematically searched from inception to February 28, 2020 with publication language restricted to English and Chinese. We included cross-sectional, case–control, or cohort studies that focused on prevalence and risk factors of HTN among Hui population. Two investigators independently assessed the risk of bias of the studies included in the review using tools developed by JBI. Meta-analysis was conducted using Stata 12.0 software package.Results:Twenty-three studies were identified with a total of 30,565 study participants. The overall pooled prevalence of HTN was 28% (95% confidence interval [CI]: 24%–32%, I2 = 98.8%, P < .001). Stratified by gender, the pooled prevalence of HTN in Hui was 26% (95%CI: 20%–33%, I2 = 97.6%, P < .001) for males and 30% (95%CI: 23%–37%, I2 = 98.3%, P < .001) for females. Pooled prevalence of HTN in Hui was 2% (95%CI: 2%–6%, I2 = 70.6%, P = .065), 10% (95%CI: 3%–17%, I2 = 83.7%, P < .001), 22% (95%CI: 12%–32%, I2 = 87.9%, P < .001), 37% (95%CI: 20%–53%, I2 = 94.0%, P < .001), 39% (95%CI: 24%–54%, I2 = 97.7%, P < .001) and 42% (95%CI: 29%–56%, I2 = 95.6%, P < .001) for those aged 18 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, and ≥70 years, respectively. Pooled prevalence of HTN in Hui was 22% (95%CI: 14%–29%, I2 = 97.9%, P < .001) in urban areas and 23% (95%CI: 16%–30%, I2 = 95.8%, P < .001) in rural areas. Daily salt intake (odd ratio [OR] = 3.94, 95%CI: 3.03–5.13, I2 = 90.2%, P < 001), family history (OR = 3.50, 95%CI: 2.60–4.71, I2 = 95.3%, P < .001), smoking (OR = 1.84, 95%CI: 1.61–2.09, I2 = 59.6%, P < .001), drinking (OR = 1.74, 95%CI: 1.26–2.39, I2 = 95.3%, P = .001), weekly meat intake (OR = 1.92, 95%CI: 1.04–3.54, I2 = 96.5%, P = .036), body mass index (OR = 2.20, 95%CI: 1.81–2.66, I2 = 91.3%, P < .001), and areas (OR = 1.29, 95%CI: 1.10–1.51, I2 = 81.5%, P = .001) were risk factors of HTN in Hui, while physical exercise (OR = 0.76, 95%CI: 0.66–0.88, I2 = 62.7%, P < .001) was protective factor.Conclusions:The pooled prevalence of HTN among Hui people was 28%, daily salt intake, family history, drinking, smoking, weekly meat intake, body mass index, areas, and physical exercise were all risk factors for HTN among Hui population. Early screening and treatment of HTN among Hui population should be given due attention. 相似文献
