查询词典 lung cancer

Down-regulated expression of PTEN and up-regulated expression of VEGF〓 were considered as two important events in tumorigenesis of ovarian cancer and could act as molecular markers to indicate the pathobiological behaviors of ovarian cancer. Decreased PTEN expression and increased VEGF〓 expression were closely associated with tumorigenesis and pathobiological behaviors of ovarian endometrioid and serous cancer respectively. Reduced expression of PTEN gene might be involved in carcinogenesis and progression of ovarian cancer by up-regulating the VEGF〓 expression to enhance angiogenesis.

在卵巢癌组织中PTEN基因mRNA表达下调和VEGF〓基因mRNA表达上调是卵巢癌发生的重要分子事件，可作为反映卵巢癌病理生物学行为的指标，且分别与卵巢内膜样癌和浆液性囊腺癌的发生和病理生物学行为关系密切；PTEN基因mRNA表达降低可能通过上调VEGF〓基因mRNA表达促进新生血管形成，进而参与卵巢癌的发生和侵袭。

The changes of appearance in buccal cancer patient due to disease itself or after remedy always has big impact on patients' body image. This study explored the adaptation process of body image for appearance changes in buccal cancer patients after surgery and examined the relationship among adaptation, social support, and body image. The purposes of this study were to: 1.explore the distribution of essential attribute, healthy behavior, disease condition, body image, body image adaptation, and social support in buccal cancer patients after operation; and 2. examine if the adaptation of body image and social support will affect patients' body image. The study usee a cross-sectional design and recruit post-operative buccal cancer patients from a regional teaching hospital at southern Taiwan.

口腔癌患者因疾病及治疗带来的外观改变，对患者心理上於身体心像的调适会形成极大的冲击，且发病年龄多集中在中壮年期的男性，本研究即探讨男性口腔癌个案术后身体心像因应及社会支持之相关性，研究目的主要针对：一、了解男性口腔癌术后不同时期患者其基本属性、健康行为、疾病情况的分布情形以及身体心像状况、身体心像因应和社会支持的情形；二、了解身体心像的影响因子为何，采用横断式研究法，以立意取样，於南部某区域教学医院的耳鼻喉科门诊，选取罹患口腔癌且经手术治疗过后的男性患者，并排除合并其他非口腔癌重大伤病者及合并其他慢性疾病造成外观改变者。

Cancer is uv's final result.shortwave radiant energy,especially from the uv b band,breaks the strandsof dna.enzymeswork constantly trearrange the dna into proper sequence.but with repeated uv exposure,the repair process may even-tually break down.then the mutantdna may produce a colony of cancer cells.but skin cancer may be avoided with a good dose of common sense.people with fair skin and blue eyes who burn easily stand the highest risk.special danger spots are the parts of the body most constantly exposed to the sun,such as the cheeks,nose,lower lip and the ears.people who have already developed precancerouslesionsor had one skin-cancer growth stand a greatly increased chance of developing others.

紫外线伤害的最终结果就是诱发癌症。短波辐射能量，特别是来自uv-b波段的辐射能量会破坏dna链。本来，酶能够按照适当的顺序来重新安排这些被打乱秩序的dna，但是持续暴露于紫外线下会让这一修复过程崩溃。到那时，变异的dna就会制造出大量的癌细胞。其实，只要运用一些常识。我们就能预防皮肤癌。浅肤色、蓝眼睛的人会轻易就被晒黑，因此他们患皮肤癌的风险就高。诸如脸颊、鼻子、下嘴唇和耳朵等长期暴露在阳光下的部位是皮肤癌的高发区域。那些已经受到癌症前期伤害或者是已经患过一次皮肤癌的人，极有可能再次患上皮肤癌。

Years old, 25 being colonic cancer,51 being rectal cancer, 31 had limph-node metastasis, 13 had distant metastasis.In the present study, 44 cases of gastric cancer with normal gastric mucosa and 62 caese of colorectal cancer with there normal mucosa was detected CD44v6 raRNA expression using reverse transcription-polymerase chain reaction.

结果 胃、大肠的正常动膜有少量CD44V6表达：胃癌、大肠癌组织CD44V6VRNA、蛋白的表达率均高于其正常锚膜（P＜0.00），44例胃癌组织 CD44V6IuRN表达阳性率在不同的性别、发生部位、大体类型、组织类型、组织学分化程度、浸润深度和TNM分期间差异无显著性。

Begg argues that all risk factors for breast cancer are overrepresented in incident cases of breast cancer, so that a sample of women who have been diagnosed with breast cancer and who are identified as mutation carriers are more likely to have other breast cancer risk factors than similar mutation carriers who are disease-free.

Dr。 Begg认为，所有的乳腺癌危险因子在乳腺癌病例中都被高估，所以一些已经被诊断为乳腺癌，且确认是某种基因突变的携带者妇女，比起具有相似的遗传突变的健康携带者，更可能是其他乳腺癌的危险因子导致疾病发生。
