Abstract］ objective to study the pathological features and histopathological type and differential diagnosis of hepatic focal nodular hyperplasia.methods the clinicopathological characteristics of 40 cases of fnh were studied.all were evaluted by use of paraffin embedded sections and he staining before light microcope observation.results there were 28 females and 12 males fnh patients whose age were from 16 to 62 years（median 41.3）,all alpha-fetoprotein was negative and had no hepatitis history.25 cases were classic type showed characteristic central stellate fibrotic scar,composed of fibrous connestive tissue and tortuous blood vessels.8 cases were telangiectic type,the left were mixed type and adenomatoid type.conclusion fnh is a reactive proliferation of hepatic cells to local blood vessel anomalies,it is not realy a tumor.its differential diagnosis includes hepatic adenomatous hyperplasia nodule,hepatic anaplasia nodular hyperplasia,fibrolamellar hepatocellular carcinoma and hepatocellular adenoma.

目的 探讨肝局灶性结节性增生的病理形态特点、组织分型及鉴别诊断。方法分析40例肝局灶性结节性增生的临床资料，并采用石蜡包埋he染色光镜下观察其组织学特点。结果 40例肝局灶性结节性增生患者中，女28例，男12例，年龄18~62岁，平均年龄41.3岁，所有病例术前均无肝炎病史，甲胎蛋白阴性，组织学上25例为经典型，有特征性的中央纤维瘢痕，由纤维结缔组织及扭曲血管组成。8例为毛细血管扩张型，其余为混合型及腺瘤样增生型。结论肝结节性增生是一种肝细胞对局部血管的异常反应性增生，并非真性肿瘤，主要与肝腺瘤样增生性结节、肝间变性结节状增生、肝纤维板层癌及肝细胞腺瘤鉴别。

Recombinant adenovirus particles were produced after 293 cells transfected with recombinant Ad genomic plasmid DNA digested with PacI, then they were further amplified in 293 cells.

纯化所得腺病毒滴度约为8×1012pfu/L，当MOI=100时，腺病毒感染HepG1细胞的效率＞75％，Western Blot证实在感染重组体腺病毒的细胞中有相应基因产物的表达。

Results:In the endometrial carcinoma tela,the lack of expression of protein pten existed in endometrioid adenocarcinoma mainly,which accounted for 60 per cent.

结果：子宫内膜癌组织中pten蛋白的失表达主要局限于子宫内膜样腺癌，占60%，5例浆液性癌中则未见pten的失表达，pten失表达在这两组肿瘤间的差异有显著性(P=0.006)，p53蛋白过表达在子宫内膜样腺癌中占26.7%，在浆液性癌中为80%，两组间差异有极显著性(P=0.001)。

Survivin and VEGF may be a stimulative factor in the progression of Colonic Adenomatous polyp and Colon Cancer for predicting adenomatous polyposis carceration and chemor-interfering carceration progress.

VEGF在腺瘤的增生、癌变、肿瘤的形成、生长和血管形成中起重要作用； Survivin可能是大肠腺瘤发展及癌变过程中的重要促进因子，对于预测大肠腺瘤癌变可能性及化学干预有重要意义。

In PsNPV infected treatment, the color of the gland was purple-black dyed with eosin and the cells were distortedly squeezed together. The tracheae nearby showed grievous pathological changes and a lot of white granules deposited around it. The pathological changes in PsGV infected treatment showed another pattern. The gland body was relative small with smaller individual cells, most of which were red dyed with eosin. The cell limits were obscure.In coinfected treatment,there were few gland cells colorated by esoin.

结果表明，不同感染组粘虫前胸腺腺体都有不同程度的组织病变，PsNPV感染组在感染晚期与前胸腺相连的气管严重病变，出现大量白色颗粒状物累积，被伊红染成紫黑色，腺体细胞被挤压变形；PsGV感染组的前胸腺腺体变小，单个细胞也小，细胞界限不十分明显；两种病毒混合感染组的腺体细胞小，能被伊红染色的细胞极少。

Results Although overexpression of P53 protein was not detected in normal eyelid cutaneous epithelium, meibomian gland and mild epithelial dysplasia, the positive rate of P53 increased in degree in moderate and severe dysplasia, carcinoma in situ and invasive tumors, and PCNA labeling index progressively increased too. Overexpression of P53 protein was detected in 30/53 cases of basal cell carcinoma, 16/32 cases of squamous cell carcinoma, 10/17 cases of meibomian gland carcinoma, and the intensity of P53 protein immunostaining increased with the lowering in the degree of histological differentiation.

结果 在正常眼睑皮肤、睑板腺及轻度不典型增生眼睑上皮中，未见P53蛋白表达，而中、重度不典型增生，原位癌，浸润癌中，P53蛋白阳性表达率逐渐增高，其 PCNA指数也有增加趋势。30/53例基底细胞癌(basal cell carcinoma，BCC)、16/32例鳞状细胞癌（squamous cell carcinoma，SCC）、10/17例睑板腺癌中，P53蛋白阳性表达；同时，随着肿瘤组织分化程度的降低，P53蛋白阳性表达程度有逐渐增高的趋势。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。

We compared the difference of gene expression between thymus in one-and ten-month old Balb/c micee using DDRT-PCR. It was found that there would be a significant difference of gene expressions in murine thymuses.

我们采用差异显示反转录PCR技术对1月和10月龄Balb／c小鼠胸腺mRNA的差异表达情况进行了分析，共获得月龄差异表达的cDNA片段108条（其中90条源于1月龄小鼠胸腺中，而有18条源于10月龄小鼠胸腺中）。
