Cryosurgery may be performed intraoperatively or percutaneously using a heavy-duty cryogenic device, with LN2 or argon as the cryogen, with an appropriate cryoprobe and probe-tip adaptor to fit the size and shape of the tumor,under the guidance of ultrasound

Tanaka应用冷冻疗法治疗34例进展型甲状腺癌，包括12例原发性，22例复发性。在12例原发性病例中，3例无病生存10年以上，2例无病生存4年后死于衰老；22例复发性病例中，7例生存10年

The fabrication processes for nano-silicon-tips using a (100) single crystal silicon wafer by the anisotropic wet etching in the KOH etchant were designed. Based on the experiment and the model of {411} crystal planes, the crystal planes of silicon tips were analyzed. Through discussing the effect of the mask direction on tip shapes, the process parameters to get high aspect ratio nano-silicon-tips were achieved.

设计了硅尖制备的工艺流程，采用KOH溶液湿法各向异性腐蚀(100)单晶硅的方法制备硅尖，根据实验结果和{411}晶面模型，分析了硅尖侧壁的组成晶面，讨论了掩模偏转方向对硅尖形状的影响，得到了制备高纵横比纳米硅尖的工艺参数。

Six days after inoculation, the cucumber root tip was slightly swollen and symmetrical root-knots were observed at the meristematic and elongation zones. Giant cells were differentiated by previous cambium cells in the center of the root; 10days after inoculation, symmetrical and secondary root-knots were observed at the root hair and upper zones. Vessels were separated by giant cells, around which protoxylem vessels were observed; l6days after inoculation, hypo-vascular tissue appeared earlier than normal; 20-30 days after inoculation, the vertical arrangement of vessels was disordered, shape was distorted and a new vascular tissue appeared in the cortex.

结果显示：接种后6 d的根尖分生区、伸长区出现膨大、对称的根结，根中心的原形成层细胞分化出巨型细胞；10 d在根毛区及以上部位出现既有对称又有偏于一侧的根结，周围有原生木质部导管出现，根结中巨型细胞阻断了导管；16 d次生维管组织提早出现；20~30 d导管纵向排列无序，形状扭曲，皮层中有新维管组织产生。
