角化的

The new study included 21 healthy volunteers with sun-damaged skin and actinic keratoses -- skin lesions that could develop into skin cancer -- on their faces.

该项研究是针对21位志愿者展开的，他们脸部的皮肤均被晒伤且患有光化性角化病-一种可演变为皮肤癌的皮肤损害。

The unique advantage of this halfanalytical numerical method is that the analytical process of Conformal Mapping can transform an irregular area into a regular one such as a rectangle. Therefore, the discretization error of numerical methods on the boundary can be avoided, and the numerical algorithm can be implemented more easily, with the computing efficiency improved.

这种保角变换的半解析数值方法的突出优点是：利用前期的保角变换解析处理将不规则的场域转化为规则的矩形域，从而避免了纯数值技术对复杂边界的离散化误差，降低了后期数值计算的算法复杂度，并提高了计算效率。

Among them,4 cases underwent vertical hemilaryngectomy and one with neoplasm excision followed cauterization.

结果 5例病人喉镜检查见声带病变局部有一定特点，病理切片可见疣状癌的特征性改变为不全角化形成、角质栓塞和推进缘。

A portion of ductal cells and individual serous acinic cells of the minor salivary gland also expressed Fas not only in membranous but also in cytoplasmic pattern.

结果发现，在正常鼻咽粘膜表面及隐窝的假复层纤毛柱状上皮细胞胞膜、部分小涎腺的导管上皮和个别浆液性腺泡上皮细胞的胞膜和胞浆Fas阳性表达；鳞状化生上皮的表层细胞胞膜有Fas表达，但基底细胞未见Fas表达；浸润的淋巴细胞也不表达Fas.45.9%（17/37）的鼻咽非角化性癌Fas阳性，但只有不足10%的癌细胞胞膜微弱表达Fas。

Germ-line mutations in the genes hTERT and hTR, encoding telomerase reverse transcriptase and telomerase RNA, respectively, cause autosomal dominant dyskeratosis congenita, a rare hereditary disorder associated with premature death from aplastic anemia and pulmonary fibrosis.

分别编码端粒末端转移酶反转录酶和端粒酶RNA的hTERT和hTR基因的种系突变导致常染色体显性先天性角化不良，它是一种罕见的因为再生障碍性贫血和肺纤维化而早亡的遗传性疾病。

Although the variability in compliancewith posttreatment tretinoin and sunscreen use is another limitationof the study, the researchers report,"We do not believe that any significant differencein posttreatment regimen adherence existed among the 3 studyarms or biased our results for actinic keratoses reduction or nonmelanoma skin cancer development."

虽然治疗后使用Tretinoin和防晒霜的变数是本研究的另一个限制，作者报告指出，我们不认为在三个研究组的治疗后处方中有任何显著差异，也不认为对我们的减少光化性角化病和预防非黑色素皮肤癌结果有任何偏见。

Reporting in the August issue of the Archives of Dermatology , Dr. Swetter and her team present the findings of their randomized prospective 5-year trial. Looking at patients with previous nonmelanoma skin cancer and severe sun damage, the group studied the effect of facial resurfacing for the treatment of actinic keratoses and prophylaxis againstnew primary basal- and squamous-cell carcinomas.

该报告登载於八月版的皮肤医学档案期刊，Swetter医师和她的团队报告此一随机前溯的五年试验研究发现，著眼於非黑色素皮肤癌和严重晒伤病患，研究脸部皮肤重建整形治疗光化性角化病，和预防初发基础细胞癌以及鳞状细胞癌的效果。

Freckles, age spots, spider veins on the face, rough and leathery skin, fine wrinkles that disappear when stretched, loose skin, a blotchy complexion, actinic keratoses (thick wart-like, rough, reddish patches of skin), and skin cancer can all be traced to sun exposure.

雀斑、色斑、脸上的红血丝、粗糙皮革化的皮肤、小细纹、皮肤松弛、肤色不匀、日光性角化病(一种厚伽，粗糙，鳞片状的皮肤病)，以及皮肤癌都能在阳光照射上找到原因。

Cavitations is the major problems of designing water hydraulic valve, understanding the relationship between shape of valve and cavitations , avoiding cavitations is extremely important, this paper, the numerical simulation and visualization research of flow field is carried out to research relation between the flow field of poppet valve and the length of valve seat by finite volume numerical method.

气穴是研制水压阀存在的主要难题，认识阀口形状与气穴的关系，避免产生气穴现象是极其重要，本文应用有限体积数值计算方法针对阀座倒角长度变化对水压阀阀道内流场的影响进行数值模拟和可视化研究，得到了一些有益的结论：倒角长度的改变对阀口间隙以及阀芯锥面与柱面相接的地方的负压会产生比较大的影响
