Disposition of the neuroleptic zuclopenthixol cosegregates with the polymorphic hydroxylation of debrisoquine in humans

The pharmacokinetics of a single oral dose of the neuroleptic drug zuclopenthixol (10 or 6 mg) was studied in 6 extensive and 6 poor metabolizers of debrisoquine. The peak plasma concentrations of zuclopenthixol did not differ between the phenotypes, whereas the plasma elimination half-life was significantly longer in poor than in extensive metabolizers (29.9 +/- 6.6 vs 17.6 +/- 6.9 h). Accordingly, the total oral plasma clearance was lower in poor than in extensive metabolizers (0.78 +/- 0.27 vs 2.12 +/- 0.65 1/h/kg). Ten of the volunteers had previously participated in a similar study in which the kinetics of perphenazine, another neuroleptic drug, were studied in poor and in extensive metabolizers of debrisoquine. There was a significant correlation between the oral clearance of perphenazine and that of zuclopenthixol among these 10 subjects. The study indicates that the disposition of zuclopenthixol, as well as that of perphenazine, is related to the genetically determined capacity to hydroxylate debrisoquine. The significance of this polymorphism for the clinical use of neuroleptics is discussed.

冠状动脉粥样硬化性心脏病患者心外膜脂肪组织的生物信息学研究

背景 心血管疾病（CVD）是常见病和多发病,患病率和死亡率呈快速上升趋势。动脉粥样硬化（AS是缺血性CVD的病理基础,研究表明心外膜脂肪组织（EAT）通过分泌外泌体（EXO）和生物活性物质促进AS进展,但其作用机制仍需进一步研究。目的 通过生物信息学方法挖掘冠状动脉粥样硬化性心脏病（CAD）患者EAT中的关键基因,探讨免疫细胞浸润情况,联合CAD患者EXO间差异表达基因（DEGs）推测EAT来源EXO间DEGs并进行验证,从细胞及分子水平上探讨EAT在CAD疾病过程中的作用机制。方法 从基因表达综合数据库（GEO）中下载关于EAT的数据集GSE64554、GSE120774,根据临床信息将EAT的测序数据分为CAD组和健康对照组,使用R语言及相关软件包进行生物信息学分析。首先使用R语言筛选CAD组与健康对照组EAT间DEGs,并进行GO富集分析和KEGG通路富集分析,构建蛋白质-蛋白质相互作用（PPI）网络,评估所选基因的生物学功能及可能参与其调控的转录因子。构建GSE64554数据集中EAT的加权基因共表达网络（WGCNA）,获取同CAD表型相关的基因模块,将所获EAT间DEGs与模...     

Establishment and Characterization of Cell Lines from Human Adenovirus Type 12-induced Murine Tumors Producing Endogenous Virus Particles

Two cell lines designated IC KMS and D KMS were established from human adenovirus type 12 induced tumors of C3Hf/OK mouse. The cell lines retained the characteristics of the original tumor i.e., production of numerous C type and intracisternal A-type particles, integration of Adl2 El region DNA and amplification of the myc gene family. Chromosomal analysis revealed chromosome aberrations in both IC KMS and D KMS cells. The modal chromosome number of IC KMS cells was 54 and that of D-KMS cells was 48. Metacentric chromosomes and mini-chromosomes were found. Trisomy of chromosome 3, 7 and 12 was seen frequently in D KMS cells. Although DNA aneuploidy was revealed by flow cytometry, the DNA indices of these cells showed no relation to the copy number of integrated Adl2 DNA. These cells have been propagated by serial culture during the past 17 months. Production of endogenous virus particles is a unique characteristic of IC KMS and D KMS cells. These cell lines would be useful materials for examining the contribution of Adl2 carcinogenesis to activation of endogenous virus particles, and also the correlation between Adl2 carcinogenesis and cancer related genes.

目的:探讨抑郁症患者大脑半球机能不对称的特点.方法:用集中注意法及两种押韵词,对58名健康被试、115名抑郁症患者进行耳优势测试.结果:1.健康组真词测听未见耳优势,而假词测听呈右耳(左半球)优势.2.抑郁症患者真词测听未见耳优势,而假词测听呈增强的右耳(左半球)优势.3.真词测听,共病焦虑障碍组无耳优势,非共病组有增强的右耳(左半球)优势;假词测听,两组均表现为右耳(左半球)优势,非共病组强于共病组.4.HAMD、HAMA、SCL-90评分与真、假词偏侧指数无相关性.结论:1.健康中国人对真词的加工与认知无耳优势,表明健康中国人在加工真词时需要左右两侧半球的协同参与;对假词的加工与认知则表现出右耳(左半球)优势,表明更为纯粹的言语材料的加工以左半球为主.2.抑郁症患者对汉字词的加工与认知,表现出较健康人强的右耳(左半球)优势.3.共病和非共病焦虑障碍者对汉字词的加工与认知,表现出较健康人强的右耳(左半球)优势,而非共病者较共病者右耳(左半球)优势强.4.患者的言语偏侧化指数与症状严重程度无相关性.5.假词为较为理想的分听材料.     

HEREDITARY HEMORRHAGIC TELANGIECTASIA WITH MALIGNANT LYMPHOMA An Autopsy Case

A 60-year-old Japanese woman was diagnosed at autopsy as having had hereditary hemorrhagic telangiectasia (HHT) associated with systemic hemangiomas. In her repoduction period, premenstrual epistaxis frequently occurred. At the age of 60, the patient died of malignant lymphoma. At autopsy, multiple telangiectatic spots were noted on the face, limbs and trunk. The paraaortic lymph nodes, which were enlarged and irregularly conglomerated, were histologically diagnosed as malignant lymphoma of the diffuse large cell type. Submucosal telangiectatic lesions were found in the gastrointestinal system from the oral cavity to the rectum. Cavernous hemangiomas were present in various visceral organs including the liver, spleen, small and large intestines, rectum, appendix, uterus, and jejunal and colonic mesenteries. There was an arteriovenous fistula in the left lung. Examination of her family pedigree showed that the patient had an autosomal dominant trait of inheritance. The pathogenesis of the systemic visceral hemangiomas observed in this patient was considered to be similar to that of hamartoma.
