舌鳞状细胞癌Tca8113细胞株醛脱氢酶高表达亚群细胞生物学特性的研究

目的检测醛脱氢酶（ALDH）在舌鳞状细胞癌Tca8113细胞株中的表达,研究ALDH高表达（ALDHhig）亚群细胞的生物学特性。方法采用流式细胞仪检测Tca8113细胞株中ALDH的表达;分选ALDHhig与ALDHlow亚群细胞,体外培养观察其增殖、分化及在无血清培养基中的成球能力;利用抑制消减杂交（SSH）技术筛选ADLHhig亚群细胞高表达基因。结果舌鳞状细胞癌Tca8113细胞株中仅有1.3%的细胞高表达ADLH;分选出的ADLHhig肿瘤细胞增殖能力高于ALDHlow细胞和未分选的肿瘤细胞;随着培养时间的延长,体外培养的ALDHhig细胞比例逐渐下降至分选前水平;ALDHhig亚群细胞能够在无血清培养基中悬浮生长形成肿瘤球,且高表达干细胞相关基因。结论舌鳞状细胞癌Tca8113细胞株中有一小群细胞高表达ALDH,具有干细胞的生物学特性;ALDH可能是舌鳞状细胞癌干细胞的标志物之一。     

Tongue metastasis originated from esophageal squamous cell carcinoma: A case report

The tongue is a rare site for metastasis. In this report, we present a woman with a history of esophageal squamous cell carcinoma who suffered from two metastatic masses on the left side of her tongue 2 years after completion of definitive chemoradiation. The patient underwent chemotherapy and left hemi‐glossectomy.     

基于HS-GC-MS和电子感官技术比较不同产地金银花气味和味道差异

目的 比较河南、河北、山东产地金银花挥发性成分、气味和味道的差异,为鉴别不同产地金银花提供参考。方法基于顶空-气相色谱-质谱法（head space-gas chromatography-mass spectrometry,HS-GC-MS）及电子鼻和电子舌2种智能感官技术对不同产地金银花药材进行测定。以变量投影重要性（variable importance projection,VIP）>1、P<0.05为标准筛选出每个产地间的差异挥发性成分。对电子鼻与HS-GC-MS结果进行pearson相关分析,使用SPSS25软件建立不同产地金银花味道判别模型。结果 经HS-GC-MS分析从金银花中共鉴定出73个挥发性成分。筛选出河南与河北、河南与山东、河北与山东样品间差异挥发性成分分别为15、11、13个,其中己醛和丁香醛为3个产地的共有差异性挥发成分。电子鼻和电子舌均能较好区分不同产地的金银花样品。通过pearson相关分析确定了11种引起金银花气味差异的挥发性成分。另外,建立的味道判别函数模型可对不同产地金银花进行准确判别。结论 HS-GC-MS、电子鼻和电子舌技术结合多元统...     

An Alternative Digital Image Correlation-Based Experimental Approach to Estimate Fracture Parameters in Fibrous Soft Materials

One of the main challenges in experimental fracture mechanics is to correctly estimate fracture parameters of a nonhomogeneous and nonlinear material under large deformation. The crack tip detection is strongly affected by fibers at crack tip, leading to inaccurate measures. To overcome this limitation, a novel methodology based on the Digital Image Correlation (DIC) method for crack tip detection of fibrous soft composites is proposed in this work. The unidirectional composite was manufactured using a matrix of polydimethylsiloxane reinforced with a single layer of extensible cotton knit fabric. For two different fiber orientations, the crack growth (da), Crack Tip Opening Displacement (CTOD) and Crack Tip Opening Angle (CTOA) were determined using pure shear specimens under mode I fracture. A consistent estimation of fracture parameters was obtained. The location of the crack tip position during the fracture test using the DIC-based methodology was validated against a visual inspection approach. Results indicated that the DIC-based methodology is easily replicable, precise and robust.     

舌鳞癌颈淋巴转移的临床研究

目的：为了探讨舌鳞癌颈巴结转移的规律及临床治疗的关系。方法：对96例舌鳞癌根治性颈清扫标本的转移性淋巴结在颈部的分布进行了回顾性分析。结果：颈部淋巴结转移病理阳性的总发生率52．1％。N0，N1，N2，N3的Ⅳ区、Ⅴ区淋巴结转移率分别为：3．3％，5．0％，30．0％，31．3％。病理证实仅有I区或Ⅱ区淋巴结转移，而无Ⅲ区淋巴结转移时，Ⅳ区、Ⅴ区淋巴结转移率为4．2％，有Ⅲ区淋巴结转移时，Ⅳ区、Ⅴ区淋巴结转移率为57．7％。结论：对于N0和N1的舌鳞癌患者可行肩胛舌骨上清扫，N2和N3的舌鳞癌者应行根治性清扫。行肩胛舌骨上清扫时，行Ⅲ区淋巴结冰冻切片检查，根据结果决定是否同时清扫Ⅳ区、Ⅴ区。     

Classification of hyperspectral medical tongue images for tongue diagnosis

Human tongue is one of the important organs of the body, which carries abound of information of the health status. The images of the human tongue that are used in computerized tongue diagnosis of traditional Chinese medicine (TCM) are all RGB color images captured with color CCD cameras currently. However, this conversional method impedes the accurate analysis on the subjects of tongue surface because of the influence of illumination and tongue pose. To address this problem, this paper presents a novel approach to analyze the tongue surface information based on hyperspectral medical tongue images with support vector machines. The experimental results based on chronic Cholecystitis patients and healthy volunteers illustrate its effectiveness.     

53例患者舌受辐射后舌苔的变化分析

1993～1995年间因头部肿瘤接受放射治疗53例患者,舌体受到较高剂量的辐射,引起舌苔明显变化,放疗期间舌苔变厚44/53例(P<0.01),舌苔变黄增至27/53例(P>0.05);放疗结束后引起少苔和光苔36/53(P<0.01)。表明舌苔变化对指导临床辨证有非常意义。     

改良的联合技术纠正中国人典型的鼻尖肥大

目的探讨中国人典型的鼻尖形态是否符合东方美貌人群的面部标准，寻找有效的手术矫正方法。方法自2006年5月至2007年7月，对25例患者实施改良的联合技术，即去除鼻尖皮下多余的组织，修剪软骨组织，置入“L”型硅胶假体及自体软骨植入，最后缝线固定和塑形等。结果本组共25例患者，术后鼻尖精巧，结构清晰，并且基本符合美貌人群的面部标准，效果满意。结论根据东方人鼻尖肥大的解剖特点，尝试将艺术和鼻整形技术结合起来，先处理鼻尖各个解剖单元，然后再按照美学标准进行组合，使操作过程细致、规范，克服了以往矫正鼻尖肥大不充分，各个解剖单元结构不清晰等缺点，为临床提供了准确地分析和判断，达到了期望的手术效果。
