Clear cell carcinomas that may occur in the lower urinary tract include variants of the more common cancers such as prostatic adenocarcinoma and transitional cell carcinoma as well as infrequent carcinomas such as clear cell carcinoma, which is similar to that of mullerian origin and metastatic renal cell carcinoma.8 A benign process that occasionally has been reported to show marked clear cell change is nephrogenic adenoma, a lesion that is considered a benign metaplastic process.3,5,12 Perhaps because of the great histo

透明细胞癌可能发生在较低泌尿系统包括变异更常见的癌症如前列腺腺癌和过渡细胞癌以及罕见的癌如透明细胞癌，它是相似的苗勒管起源和转移性肾细胞癌 18亿美元的良性碾压工艺，偶尔被报告显示标记为透明细胞变化腺瘤，被视为是一种良性病变的化生 process.3，5，12也许因为伟大的历史

There were 22 malignant tumors including 11 osteosarcomas, 5 chondrosarcomas, 2 malignant fibrous histocytomas, and one each of malignant osteoblastoma, alveolar sarcoma, rhabdomyosarcoma, malignant giant cell tumor of bone. 28 benign tumors included 27 giant cell tumors of bone and 1 benign fibrous histocytoma.

为寻找良性骨缺损理想的充填材料，特别是修复儿童良性溶骨性较大的骨缺损，采用天然型无机骨充填良性溶骨性骨缺损5例，其中骨囊肿3例，纤维异样增殖症1例，非骨化性纤维瘤1例。

The chromatin unfolding assay showed that ,like the wild-type transactivation domain, two variants that represent benign polymorphisms did not induce chromatin unfolding or only induced subtle change. Contrary to the behaviors of the wild type and two benign variants, four cancer-predisposing mutations in the transactivation domain superactivate the chromatin unfolding. The results suggest that the chromatin unfolding assay can aid in the characterization of deleterious mutations in the C-terminal transactivation domain of BRCA1 and may provide more reliable presymptomatic risk assessment.

对这些重组质粒的染色质伸展活性检测表明，野生型pwt和两种良性多态性突变体不具有染色质伸展活性或只有极微弱的染色质伸展活性，而其他4种乳腺癌易感突变体均具有过强的染色质伸展活性，提示利用染色质伸展技术可预测BRCA1转录激活区基因型与乳腺癌发生风险的表现型的关系。

Methods DNA aneuploid and TA were detected respectively in 165 cases of malignant pleural effusion and 127 cases of benign dropsy of chest (benign group, including tuberculous,other effusion and transudate of chest) by FCM and TRAPHybELISA.Carcinoembryonic antigen was also detected in the two groups.The difference of DNA aneuploid and TA between these two groups was analyzed.

恶性积液165份、良性积液127份(包括结核性、其他渗出液、漏出液)，应用流式细胞术检测DNA异倍体、端粒末端重复序列扩增—杂交—酶联免疫分析技术检测TA，同时检测临床常用的癌胚抗原，比较各类积液中上述3项指标检测结果的差异。

The studies exploring the relationship between HPV infection and laryngealcarcinoma began in 1980s,since then,almost all the research was aimed at theinvestigation of the HPV prevalence in the biopsies,due to differences in thechoice of DNA detection method,cell sampling and the geogen,the prevalenceestimates of HPV have varied accordingly,and led to two different points about therelationship between HPV infection and laryngeal carcinoma:some researchersdemonstrated that a higher HPV prevalence could be found in laryngeal carcinomas(from 50% to 90%)than in benign laryngeal lesions,suggesting a relationshipbetween HPV infection and laryngeal carcinoma;but the other researchers foundthat the isolation of HPV is no greater in the laryngeal cancers(from 5% to 43.3%)than in the normal larynx or benign laryngeal lesions,thereby questioning itsctiological significance,so,the role of HPV in the development of laryngealcarcinomas still remains unclear.

有关HPV与喉癌的研究始于80年代，但20多年来研究模式始终停留在对临床标本进行检测的水平上，由于各家采用的检测手段敏感性不同、标本数量以及来源地域也存在差异，使各家学者对喉癌中HPV阳性率的报道极不一致，并由此导致了两种截然不同的观点：一部分学者报告的喉癌标本中HPV阳性率高达50%~90%，并显著高于喉良性肿瘤，认为HPV与喉癌有关；而另有不少学者检测的样本中，阳性率（5%~43.3%）并不比正常喉粘膜及良性肿瘤高，认为HPV与喉癌无关，因此，HPV到底是不是喉癌的致癌因素目前仍无定论。

With the aim of elucidating features which may help with differential diagnosis, this study reports the incidence and pathologic features of benign ovarian alterations, benign ovarian tumors, and occult primary and metastatic malignancies in prophylactic oophorectomies from 108 women with a BRCA mutation and from 35 women with other strong risk factors for hereditary breast/ovarian carcinoma.
