皮肤癌

It is well known that ultraviolet radiation induces derma cancer especially in white European and American with epidemic investigation reports.

流行病调查表明，紫外线辐射可能诱发皮肤癌，其中包括黑色素和非黑色素皮肤癌，特别在欧美白人中。

The good news about skin cancer is that it is rarely fatal and skin cancer is not responsible for many deaths.

好消息，关于皮肤癌的是，这是很少致命和皮肤癌是不负责的许多人死亡。

With each hour,the sun's ultraviolet radiationproduces irreversibledamage,hastening the development of unsightly wrinkles.and with each year oii the beach or rooftop,the sunbather increases his risk of getting skin cancer.skin cancer is by far the most common form of cancer.an estimated 400,00 new cases will be blamed this year in the united states.and almost all of them can be blamed on over-exposure to the sun.

太阳紫外线无时无刻不在制造永久性伤害，加速了那些难看的皱纹的产生。而每年，随着日光浴者在海滩或者房顶所花的时间越来越多，他们患皮肤癌的危险性也越大。如今，皮肤癌是最常见的一种癌症。在美国，今年将有可能新增四十万病例，而其中大多数要归咎于过度暴晒。

The risk increases in summer because ultraviolet rays from the sun are the main cause of skin cancer.

阳光中的紫外线是导致皮肤癌的主要原因，因此夏天患皮肤癌的危险更大。

Multiple CSCCs carry a high risk of subsequent primary skin cancer. CSCCs arising in a scar have higher rate of recurrence or metastasis than those occurring in actinic keratoses. A patient presented with primary CSCCs on the ankle and wrist.

多处原发性皮肤癌病患比起一般皮肤癌患者，有更高的机会发生次发性皮肤癌，且源於疤痕或慢性砷中毒的扁平上皮细胞癌，其侵袭性、复发率、转移可能性，及并发其他疾病的可能性也比源於紫外线暴露者为高。

"Long-term skin cancer and actinic keratoses surveillance continue to be important,and repeated resurfacing procedures or courses of topical agents,such as fluorouracil or imiquimod, may be necessary," the researchers write."A largerstudy comparing trichloroacetic acid resurfacing for actinic keratoses reductionand nonmelanoma skin cancer prophylaxis would help validate the superiority ofthis resurfacing technique over the carbon dioxide laser andassess its cost-effectiveness compared with photodynamic therapyor imiquimod treatment." They cite improved patient compliance in the trichloroacetic-acid group, ease of performance in the outpatient setting, andsubjective measures of better tolerance as reasons this procedure is an attractive alternative to repeated courses with topicalagents or laser resurfacing.

研究者指出，长期皮肤癌和光化性角化病之监测仍是重要的，反覆的皮肤重建整形步骤、或外用制剂如fluorouracil 或 imiquimod的反覆疗程也可能是必须的；一个比较三氯醋酸皮肤重建整形以减少光化性角化病和预防非黑色素皮肤癌的大型研究，将可有助於确定其优於二氧化碳雷射的优势，以及评估其和光动力治疗或 imiquimod治疗之花费效益比比较；他们举例说，三氯醋酸组病患之遵医嘱性增加、门诊病患也容易进行、个案之测量耐受度比较佳，这些都是重复疗程时比外用药剂或雷射更有吸引力的理由。

A history of sunburns early in life also increases the risk. So does a family history of skin cancer.

早年有晒伤史或有皮肤癌家族病史的人患皮肤癌的危险也较大。

While this technology is promising and may eventually be useful as a diagnostic tool for basal-cell carcinoma and other skin cancers, Dr. Petri cautions that this is still basic research."We are not anywhere near being able to use this clinically," he told Medscape Oncology ."But looking into possible future applications, this technology could be used to identify patients at high risk of skin cancers or to evaluate a suspected lesion if the patient wishes to avoid a biopsy."

Petri博士表示，虽然本技术看似有用，且最后可能可以作为基底皮肤癌和其他皮肤癌的诊断工具，但这仍只是基础研究，他向Medscape Oncology表示，我们还未达可以临床运用此技术的境界，不过，著眼於未来的运用，本技术可以用来辨识高风险皮肤癌患者，或者用来评估希望避免切片之病患的可疑病灶。

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。

Them responded requesting 37,000 copies of booklets and 2,300 posters.

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
