Recently, the gene responsible for nevoid basal cell carcinoma syndrome, an autosomal dominant disorder characterized by multiple malformations and susceptibility to a variety of tumors and, particularly, to BCC, has recently been identified as PTCH.

痣样基底细胞癌症候群是一种体染色体显性遗传疾病，其主要表现有基底细胞癌、成齿的角质囊肿和其他多种骨骼发育异常，这个疾病被认为和PTCH基因突变有关。

Many factors may be involve in the course. To investigate the regulation activity of mesenchymal cells to differentiation of epithelial cells from hair follicle and to study its differentiation property, mesenchymal cells gel was made by nubby dermal papilla cells, free dermal papilla cells, skin fibroblasts. Skin keratinocytes and epithelial cells from hair follicle were inoculated on the gel surface and cultured in air-liquid interface. Three-dimensional model of DPC using to induce epithelial cells differentiation is built in vitro.

为了进一步研究毛囊细胞间的相互作用，探讨毛囊间质细胞对毛囊上皮细胞分化的调节作用，研究毛囊上皮细胞的分化特性，我们利用团块状的毛乳头细胞，游离分散的毛乳头细胞或皮肤成纤维细胞制成间质细胞胶原凝胶，表面接种皮肤角质形成细胞或毛囊上皮细胞，进行气-液界面培养，在体外建立了毛乳头细胞诱导毛囊上皮细胞分化的立体模型。

The ingredients can effectively improve skin blood capillary, opsonize skin blood microcirculation, enhance skin peroxidation, and prevent melanin from moving toward epedermis, effectively reduce pigmentation and over corinification , and realize apparent whitening and skin care functions.

功效原理：配方成分能有效改善皮肤毛洗血管，调理皮肤微循环，促进皮肤细胞有氧代谢，防止皮肤过氧化，阻止黑色素向皮肤表层转移，有效降低色素沉着和过度角质化，具有显著的美白和护肤双重功效。

The integrate study, especially careful cuticle analysis on Populus davidiana Dode on Mesozoic and Cenozoic fossil plants of Lanzhou-Minhe Basin, was made by use of environmental palaeobotany method.

运用环境古植物学的研究方法，对兰州-民和盆地的中、新生代植物化石进行了综合分析，特别是对其中的新生代山杨做了细致的角质层分析。

On March 3, the child developed a generalized papular vesicular rash on the face, neck, and upper extremities, and was transferred to a tertiary-care facility in Chicago where contact precautions were implemented. He had had a fever 2 days before his hospital admission and weeping skin lesions beginning on February 24. By March 7, the rash had worsened, with umbilicated lesions with an erythematous base, mostly on the hands, forearms, neck, chest, face, and knees, encompassing 50% of the keratinized skin.

到了3月3日，该名28个月大的儿童在脸部、颈部和上肢长出全身性丘疹水泡，而被转诊至芝加哥的一所第三级医疗单位，於该处执行接触传染预防措施；该名儿童在住院前两天发过烧，且自2月24日开始因皮肤的水泡难耐而哭泣；到了3月7日，发疹病况持续恶化，形成红斑性基底的脐形水泡，大多是长在双手、双臂、颈、胸、脸和双膝上，包括50%的角质化皮肤。

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

结果：CDK4、P16均表达于胆脂瘤上皮的棘细胞层、颗粒层和角质层，阳性率分别为68.6%、88.6%，高于对照组(前者P=0.011，后者P=0.02)。

Both upper and lower epidermis cells are polygonal or irregular in shape in all species studied. The patterns of anticlinal walls are straight, arched or sinuous, and the raphal cuticular striastriae are occasionally observed on periclinal walls. Stomatal apparatus and secretory cells are found on the upper epidermis of several species and on the lower epidermis of all Species. The slomata apparatus mainly belong to the paracytic type and latercylic type; rarely anomocytic type occurs along with the paracytic one.

结果表明：这些植物叶片的上、下表皮细胞呈多边形或不规则形，垂周壁式样为平直、弓形或波浪状，平周壁偶有脊状条纹；少数种类上表皮还有气孔器或分泌细胞，所有种类下表皮具气孔器和分泌细胞；气孔器类型以平列型和侧列型居多，偶尔有无规则型；气孔极区呈稍角质加厚或棒状加厚，稀T形加厚。
