我对韩国火病(Hwa-Byung)的认识

火病(Hwa-Byung)是韩国人很熟悉的心身疾病之一,属于韩国人固有文化相关综合征。反而此韩国火病在中医界并不熟知,本文收集和整理了目前有关火病的内容,介绍韩国火病的实际现状。韩国庆熙医疗中心韩方神经精神科通过使用choseunghun开发软件即"火病认定的标准诊断协议",在2004年5月至11月以门诊患者为主进行研究,确定患者辨火病的辨证类型结果如下,其中最多的辨证类型心阴阳两虚证(15),气血两虚证(5),少阳邪气弥漫三焦证(8),热扰胸膈证(8),痰火扰心证(7)。     

蜚蠊提取液改善阴道微生态及治疗宫颈持续性高危型人乳头瘤病毒感染的研究

目的观察蜚蠊提取液联合干扰素对宫颈持续性高危型人乳头瘤病毒（high-risk human papillomavirus, HR-HPV）感染的治疗效果,并比较治疗前后阴道微生态及宫颈局部细胞免疫功能变化。方法按病例纳入和排除标准纳入宫颈持续性HR-HPV感染患者80例随机分为2组,每组40例,对照组使用干扰素阴道纳入治疗,研究组在对照组的基础上加用蜚蠊提取液进行阴道冲洗,两组均治疗3个疗程。在治疗前后分别进行宫颈HR-HPV检测、阴道微生态评价及宫颈细胞免疫功能检测。结果治疗后研究组宫颈持续性HR-HPV感染转为阴性24例（61.54%）,对照组转为阴性13例（33.33%）,研究组治疗宫颈持续性HR-HPV感染的效果明显优于对照组（χ2=6.221,P=0.013）;研究组治疗后阴道微生态失衡（χ2=6.642,P=0.010）、乳杆菌分级异常（Ⅱb或Ⅲ级,χ2=6.271,P=0.012）、革兰阴性短杆菌（χ2=7.508,P=0.006）、革兰阳性球菌（χ2=8.419,P=0.004）、pH值异常（χ2=4.198,P=0.040）、H2O2阳性（χ2=5.769,P=0.016）及AV检出（χ2=4.255,P=0.039）等指标较治疗前得到明显改善（P＜0.05）;对照组治疗后仅在pH值异常改善方面与治疗前差异有统计学意义（χ2=7.429,P=0.006）;两组间治疗后比较,研究组对阴道微生态失衡的治疗效果较对照组更明显,具有显著性差异（χ2=4.446,P=0.035）;治疗后研究组宫颈细胞免疫功能改善比对照组更明显,CD4（t=-4.741,P＜0.001）、CD8（t=-4.725,P＜0.001）、CD4/CD8（Z=-5.022,P＜0.001）、TNF-α（t=-4.912,P＜0.001）、IL-4（t=-2.162,P=0.034）差异均具有统计学意义（P＜0.05）。结论蜚蠊提取液清利湿热、活血解毒等功效,与干扰素合用可显著提高宫颈持续性HR-HPV感染的治疗效果,其作用可能与通过纠正阴道微生态失衡及改善宫颈局部细胞免疫功能相关。     

太子参葛根淫羊蕾复合物抗抑郁作用:与NRSF/NRSE-TPH2信号相关

抑郁症属于心理性疾病且无特效疗法.本文对由太子参多糖、葛根淫羊藿总黄酮组成的太子(TZ)胶囊的抗抑郁作用进行了实验研究.利用整体动物悬尾和强迫游泳方法观察TZ的抗抑郁药效,构建了五羟色胺羟化酶2(TPH2,tryptophan hydroxylase-2)质粒对TZ进行体外实验研究,利用qPCR和Western blo...     

Novel spontaneous myelodysplastic syndrome mouse model

BackgroundMyelodysplastic syndrome (MDS) is a group of disorders involving hemopoietic dysfunction leading to leukemia. Although recently progress has been made in identifying underlying genetic mutations, many questions still remain. Animal models of MDS have been produced by introduction of specific mutations. However, there is no spontaneous mouse model of MDS, and an animal model to simulate natural MDS pathogenesis is urgently needed.MethodsIn characterizing the genetically diverse mouse strains of the Collaborative Cross (CC) we observed that one, designated JUN, had abnormal hematological traits. This strain was thus further analyzed for phenotypic and pathological identification, comparing the changes in each cell population in peripheral blood and in bone marrow.ResultsIn a specific‐pathogen free environment, mice of the JUN strain are relatively thin, with healthy appearance. However, in a conventional environment, they become lethargic, develop wrinkled yellow hair, have loose and light stools, and are prone to infections. We found that the mice were cytopenic, which was due to abnormal differentiation of multipotent bone marrow progenitor cells. These are common characteristics of MDS.ConclusionsA mouse strain, JUN, was found displaying spontaneous myelodysplastic syndrome. This strain has the advantage over existing models in that it develops MDS spontaneously and is more similar to human MDS than genetically modified mouse models. JUN mice will be an important tool for pathogenesis research of MDS and for evaluation of new drugs and treatments.     

MMP-1中单核苷酸多态性与贵州汉族人的非小细胞肺癌易感性

目的:研究基质金属蛋白酶1(metal matrix proteinase-1,MMP-1)启动子区-1607 bp处1G或2G单核苷酸多态性(single nucleotide epolymorphism,SNP)与贵州汉族人非小细胞肺癌(non-small cell lung carcinoma,NSCLC)遗传易感性的关系.方法:采用聚合酶链反应 - 限制性片段长度多态性(polymerase chain reaction-restriction fragment length polymorphism,PCR-RFLP)方法分析71名NSCLC患者和75名健康对照者的MMP-1启动子区SNP的基因型,比较不同基因型与NSCLC发生风险的关系.结果:2G/2G基因型在NSCLC组中分布频率高于健康对照组.2G/2G基因型较1G/1G及2G/2G 1G/2G基因型患NSCLC风险率增加,OR(95%CI)值分别为3.082(1.620～5.862),2.517(1.283～4.936),吸烟可增加2G/2G基因型患NSCLC风险率.结论:贵州汉族人群MMP-1启动子区SNP(1G/2G)基因型与NSCLC易感性有关,2G/2G基因型的NSCLC发生风险增加.
