Kaposi肉瘤患者病情进展与HHV-8病毒载量相关性的研究进展

Kaposi肉瘤（Kaposi’s sarcoma，KS）、部分多中心血管滤泡淋巴增生症（multi—centriccastle—man’s disease，MCD）和原发性渗出性淋巴瘤（primary effusion lymphoma，PEL）等和AIDS相关恶性肿瘤的发生与人类疱疹病毒8型（Human Herpesvirus-8，HHV-8）密切相关[1]。HHV-8是一种重要的具有高度致癌性的人类肿瘤病毒，在HHV．8相关的疾病中，KS最为多见。研究表明，在Kaposi肉瘤患者的瘤组织中，HHV．8DNA检出率为80％～100％[2]。随着实时荧光定量     

唾液能传染卡波济氏肉瘤?

新奥尔良消息:西雅图研究人员已在男性同性恋患者的唾液中发现了与卡波济氏肉瘤(KS)相关的病毒,并认为唾液接触可能是传染KS的一条途径。研究人员的上述发现受到持怀疑态度的流行病学家的欢迎,许多有关行为方面的研究已表明精液接触与发生KS密切相关。在AIDS中,几乎仅在同性恋男性患者中发现KS,这表明KS本身可能就是一种通过性活动传播的疾病。两年前,研究人员在KS病变中检出一种新的疱疹病毒,即人疱疹病毒8(HHV8,亦称     

卡波氏肉瘤病因学的研究进展

卡波氏肉瘤（Kaposi＇s sarcoma，KS）是一种缓慢进展的软组织恶性多发性色素性血管肉瘤，主要见于皮肤，也可累及内脏。根据临床表现、生物行为及特点不同可分为经典型、艾滋病相关型、非洲地方型、免疫抑制／器官移植相关型。KS病因学一直未能确定，KS是AIDS的早期表现之一，也是艾滋病（AIDS）最常见的原发性肿瘤和致死原因，鉴于其对AIDS的特殊价值，KS引起广泛关注。现将其病因学的研究进展综述如下。     

济南地区献血者中人疱疹病毒8型（HHV 8）IgG抗体的检测及相关危险因素分析

目的：了解人疱疹病毒8型（HHV 8）在济南地区不同献血者中的感染情况，并对其与年龄、性别、HBV、HCV、梅毒螺旋体的相关性进行统计学分析。方法：以HHV 8 ORF K8.1合成多肽为抗原，采用ELISA方法检测献血者血清中相应IgG水平。结果：520份血清中抗HHV 8 ORFK8.1抗体的总体检出率为5.962%（31/520），有随年龄增加而增高的趋势，但与性别、HBV、HCV、梅毒螺旋体的相关性无统计学意义。结论：济南地区献血者中有一定比率的HHV 8感染。采取措施，防止HHV 8经输血传播具有一定的现实意义。     

艾滋病相关的卡波西肉瘤免疫激活状态研究

目的：进一步探讨免疫功能改变在艾浚病相关的卡波西肉瘤(AIDS—KS)发病中的作用。方法：对12例AIDS—KS，32例无卡波西肉瘤的HIV感染者(HIV—NKS)和16例正常对照进行了研究，用ELISA对8例AIDS—KS，28例HIV—NKS和16例正常对照血清(或血浆)进行了sFas，β2—微球蛋白(β2—MG)，IL—l0，IL—16，IL—l8，IL—6和可溶性IL—4受体(sIL—4R)测定，对l2例AIDS—KS，32例HIV—NKS外周血淋巴细胞、淋巴细胞亚群及CD38^ CD8，HLA—DR^ CD8进行了分析。结果：β2—MG，sIL—4R水平在HIV—NKS组明显高于正常对照组，IL—16水平在HIV—NKS组明显低于正常对照组，IL—18水平在HIV—NKS组和AIDS—KS组均明显高于正常对照组；CD3、CD4、CD8、NK、HLA—DR^ CD8在AIDS—KS均低于HIV—NKS，而AIDS—KS组CDl9、CD38^ CD8高于HIV—NKS组，但各组间差异无显著性。结论：AIDS—KS和HIV—NKS一样存在一定程度的免疫救活，但AIDS—KS和HIV—NKS间免疫状态无明显差异，提示免疫状态的差异可能不是艾滋病患者并发卡波西肉瘤的主要原因。     

HHV6和HHV7感染与类风湿性关节炎的相关性

目的 探讨人疱疹病毒6型（HHV6）和7型（HHV7）感染在类风湿性关节炎（RA）病因学中作用。方法 用巢式PCR技术，检测62例类风湿性关节炎病人和138例健康献血员外周血单个核细胞（PBMCs）和血浆中HHV6和HHV7DNA。结果 类风湿性关节炎病人组PBMCs中HHV6和HHV7DNA阳性率与正常对照组比较均无显著性差异（P〉0．05）；部分类风湿性关节炎病人血浆中可检出HHV6和HHV7DNA，而对照组血浆中则为阴性。结论 类风湿性关节炎病人中可能存在HHV6或HHV7的活动性感染，与类风湿性关节炎的发生发展有一定关系。     

人类疱疹病毒8型诊断学的研究进展

HHV-8又名Kaposi肉瘤相关疱疹病毒（Kaposi’s sarcoma-associated herpesvirus，KSHV），是Kaposi肉瘤（Kaposi’s sarcoma，KS）、原发性渗出型淋巴瘤（Primary effusion lymphoma，PEI。）以及多中心性Castleman病（multicentric Castleman disease，MCD）的重要病原体。它是由Chang等1994年采用代表性差异分析法从1例AIDS相关性KS患者的KS病变组织中发现的。本文就近年来HHV-8的生物学特性及其诊断学的研究进展综述如下。     

人疱疹病毒8型在HIV相关型Kaposi肉瘤发病机制中作用的研究进展

1994年人疱疹病毒8型(HHV -8)被确定为具有某些人Kaposi肉瘤(KS)的感染性因素后,几乎在所有类型的KS中均可观察到HHV -8感染.之后人们对HHV -8的病毒学、致病机制及临床预后进行了广泛、深入的研究.1人疱疹病毒8型相关型卡波西肉瘤(KS)概述KS是一种血管源性肿瘤,又称多发性、特发性出血性肉瘤.自Kaposi氏于1872年报告本病至今已有100余年的历史,有关KS的病因学一直未能确定.按照Kaposi描述的多中心发生,全身皮肤及内脏血管广泛受累,紫色的结节性皮肤皮损,被称为经典的KS.

230例健康献血者卡波氏肉瘤相关疱疹病毒感染的血清学检测

卡波氏肉瘤相关疱疹病毒(Kaposi’s sarcomaassociated herpesvirus，KSHV)又称人疱疹病毒8型(HHV-8)，是1994年美国学者Chang等首先从AIDS患者卡波氏肉瘤(KS)组织中发现的一种新的肿瘤病毒，目前被认为是KS的致病因子。KS是AIDS患者最易患的一种血管瘤，在AIDS患者中的发病率可高达50％。后来的研究表明，KSHV与多中心性卡斯特莱曼病、原发渗出性淋巴病等多种疾病有关。另外，流行病学研究表明，     

Value of D-Dimers in patients with acute aortic dissection

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P ＜ 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (＞0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P ＜0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P ＜ 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.

Methods：OPGmRNA and ODFmRNA in the bone tissue in 50 cases of osteoporosis sufferers（over 50 years old） with hip fracture（Observer Group） and 30 cases of hip facture sufferers with no osteoporosis（Control group） were analyzed with the Semi-Quantitative RT-PCR method. Results：The mRNA expressed of ODF, OPG were both high in the patients with hip fracture. In the control group, the expression of OPG mRNA was observed, while the expression of ODF mRNA was very slight. Conclusion：Aged patients contained all signals including OPG, ODF that are essential for inducing osteoclastogenesis and promoting bone resorption.     

The clinicopathological and immuohistochemical analysis of solid-pseudopapillary tumor of the pancreas： report of 9 cases

Objective：To investigate the clinical features, pathological characteristics and immunophenotype of solid-pseudopapillary tumor of the pancreas（SPTP）. Methods：Nine surgically treated cases of SPTP were retrospectively reviewed. Hematoxylin and Eosin（HE） staining and immunohistochemical staining were used to analyze all cases, and the general clinical data was collected. Results：Six patients were asymptomatic except for a palpable mass. Two patients complained of vague-epigastric pain. One patient appeared jaundice. The tumor was encapsulated and solid tissues alternately with cystic tissues. Histologically, the histological structure of solid portion was pseudopapillary with a fibrovascular core. Tumor cells were uniform and medium-sized which were arranged in sheets ets or nests or pseudopapillary patterns. Immunohistochemical studies demonstrated that SPTP proved positive in vimentin（9/9 cases）, AAT（9/9 cases）, NSE（9/9 cases）, ACT（7/9 cases）, CK20（2/9 cases）, CgA（1/9 cases）, S-100（3/gcases）, PR（4/gcases）, Syn（3/9 cases） and CD56（5/9cases）, negative in CEA and ER. Conclusion：SPTP is a tumor predominantly occurring in young women frequently without special symptoms. This tumor has various characteristical histological patterns with different immunophenotype.

Investigation of Matrix Metalloproteinase -1, 2 and tissue inhibitor of matrix metalloproteinases-1 in Endometriosis

Objective： To explore the role of matrix metalloproteinase-1,2 （MMP-1, MMP-2） and tissue inhibitor of matrix metalloproteinases-1 （TIMP-1） in endometriosis. Methods： The eutopic and ectopic endometria from 40 subjects suffering from endometriosis and regular.endometria from 40 subjects （excluding endometriosis） were collected and examined by in situ hybridization technology and western blot assay. Results： Both expressions of MMP-1 and -2 were stronger in ectopic endometrium and eutopic endometrium than in normal endometrium. On the contrary, the expression of TIMP-1 in ectopic endometrium and eutopic endometrium was lower. The differences were significant （P 〈 0.01 ）. Moreover, there was no relationship among the expressions of MMP-1, 2 and TIMP-1 in ectopic endometrium. Conclusion： The expressions of MMP-1, 2 and TIMP-1 lose balance and lack of periodic changes in ectopic endometrium , which explains the biological invasive behavior of endometriosis. It was suggested-that regulating the balance between the MMPs and TIMP-1 should be an ideal therapeutic target to endometriosis.
