With western blot analysis and DNA polymerase chain reaction-single strand conformation polymorphism assay,protein product of Rb gene and mutation in exon 5～8 of P_(53) gene were examined in 17 cases of human testicular seminoma.

采用Western印迹和DNA聚合酶链反应－单股构造多态性分析法对17例人睾丸精原细胞瘤组织标本的抗癌基因Rb表达的蛋白产物和P_（53）基因外显子5～8的突变进行检测，发现有3例标本的Rb基因表达的蛋白产物缺失，有4例标本的P_（53）基因有点突变，对照的正常人睾丸组织和视网膜组织均呈Rb基因蛋白产物表达阳性，对照的正常人睾丸组织中未发现P_（53）基因突变。

Pleomorphic adenoma is the most common gland tumor of parotid origin, accounting for 60 to 70%. This kind of tumor usually presents as a slow-growing painless mass anteroinferior to the ear. The diagnosis is based on physical examination, image studying and even fine needle aspiration biopsy. The optimal method of treatment of such tumors is local excision or paroidectomy in which the entire capsule is totally dissected off but the facial nerve is spared. Diagnosis and treatment planning are focused on preventing tumor recurrence and consequent malignant transformation.

腮腺之多形性腺瘤乃是唾液腺最常见的肿瘤，约占所有唾液腺良性肿瘤的百分之六十至七十，这类的肿瘤在临床上的表现常是耳下缓慢增生的无痛性肿块，临床上诊断的依据必须配合临床检查、电脑断层扫描、磁振造影及细针抽取切片的病理检查方可得知，其治疗方式主要是对肿瘤进行局部切除手术或腮腺的切除手术，手术中颜面神经需小心保留，但须将肿瘤的外膜部分切除乾净，诊断及治疗计画著重在预防肿瘤复发及肿瘤产生恶性转变。

"Many more children could be cured without the risk of long-term side effects of treatment if we could identify at presentation subgroups of those who could safely avoid treatment with cardiotoxic chemotherapy drugs and radiotherapy," senior author Kathy Pritchard-Jones, from Royal Marsden Hospital NHS Trust in Sutton, England, says in a news release.

在新闻发布会上，英国萨顿市Royal Marsden医院NHS Trust的Kathy Pritchard-Jones说：如果我们能早期发现，更多的患有〔Wilms瘤〕的儿童可以不必接受长期有副作用的治疗方法，这些孩子可以不必接受有心脏毒性的化疗和放疗的治疗，相对应的是，这种疾病极低的生存率，可以通过早期的强化治疗来改善。

mitochondrial dnais the only inheritant substance except for the nuclear dna in a euˉkaryon cell,which is related to the oxidative phosphorylation of a cell.mitochondrial dna is the important target of carcinogens and is vulnerable because of its structure and function.the mutation of mtdna could reduce the nomal respitation and release large quantities of ros,whichincrease the danger of cancer happening.so,mtdna has been thought to be involved in carcinogenesis and recently more and more studies in this aspect have comeout.in this paˉper,we review the researches for relationship among mtdna mutation and tumors in digestion system,woman system,head and neck,urinary systemand blood system.

线粒体dna（mitochondrial dna，mt dna）是真核细胞中唯一存在的独立于核dna之外的遗传物质，与细胞的氧化磷酸化功能密切相关。mtdna自身的结构和功能特点决定了它是致癌物作用的重要靶点，易受致癌因素的损伤而发生突变。mtdna的突变可削弱正常的呼吸功能，释放高水平的活性氧，进而增加肿瘤发生的危险性，所以mtdna被认为与肿瘤发生有密切关系。近年来，这方面的研究越来越多，本文现就mtdna突变与消化系统肿瘤、妇科肿瘤、头颈部肿瘤、泌尿系统肿瘤等实体瘤以及血液系统恶性肿瘤之间的关系作一简单的综述。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
