The molecular basis of chemoresistance is poorly understood, precluding adances in glioma treatment and leaing gliomas among the most lethal tumors.

药物抵抗的分子基础尚未被很好的阐明，排除了对治疗敏感的胶质瘤，而留下的胶质瘤便是最为致命性的。

Objective: We have studied Baizhus effects of suppressing tumors and anti-metastasizing during our pretests. In order to discuss the mechanism further, we have respectively studied its effects from three aspects.

目的：预试验对于白术抑瘤及抗肿瘤侵袭和转移的作用进行了研究，确定白术具有抑瘤及抗肿瘤转移的作用，为进一步探讨其机理所在，本研究从三方面作了更细致的研究。

Successful embolization was defined as greater than 95% occlusion of the dome without any coil prolapsing into the parent essel.

成功的栓塞是这样定义的：大于95％的瘤体被栓塞且没有螺圈脱出进入载瘤血管。

In fact, how to choose the treatment method for a patient with acoustic neuroma, what limits resecting tumor to be more reasonable and when the tumor to relapse after operation, etc.

随着人们对听神经瘤生长方式的认识，外科手术已不再是治疗听神经瘤的唯一方法，放射治疗和动态影像学观察也越来越受到重视。

The glioma's invasive tissue is the recurring source of glioma in clinical treatment, even after resecting glioma.

在胶质瘤治疗的过程中，即使肿瘤组织自身被切除，浸润组织则是胶质瘤复发的根源。

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

PURPOSE: To investigate the combined effects of adenoviral-mediated p53(Ad-p53) transgene expression and irradiation response in nude mice models of lung adenocarcinoma (A549 and GLC-82).To determine whether wtp53 sensitizes cells to radiation independently of their p53 status and to investigate the interaction mechanism.

目的：本研究筛选了P53基因状态不同的两种人肺腺癌细胞系A549及GLC-82，分别建立裸鼠人肺腺癌移植瘤模型，使用E1复制缺陷型重组腺病毒介导的野生型P53基因瘤内注射治疗，观察其放射增敏作用并探讨其机制，同时比较不同P53基因状态对治疗的影响，为临床开展基因放射治疗提供实验依据。

Mature teratomas of benign tumors, and said, skin samples cyst is one of the most common ovarian tumor, ovarian tumors by 10%— 20%, germ cell tumors of 85%— 97%, 95% teratomas.

成熟畸胎瘤属良性肿瘤，又称皮样囊肿，是最常见的卵巢肿瘤，占卵巢肿瘤10%～20%，占生殖细胞肿瘤85%～97%，占畸胎瘤95%以上。

Up to now however, there has been no evidence that PET leads to improved management of patients in routine clinical practice. We did a randomised controlled trial in patients with suspected non-small-cell lung cancer, who were scheduled for surgery after conventional workup, to test whether PET with 18FDG reduces number of futile thoracotomies.

首先，在原发瘤的评估方面，其作用目前仅限于对单发肺内结节的良恶性鉴别，并且阳性预测值相对较低，在肿瘤可切除性评估方面的作用远逊于CT；更何况肺内良性肿瘤也需要手术切除，而那些不需要手术的病灶，比如活动性结核瘤及炎性肿物，PET 的假阳性率又太高。

The B, C, D group each mouse right armpit department hypodermic vaccinates the H22 lump cell to hang fluid 0.2ml, after vaccinating 24h weighing, and starts the abdominal cavity injection to give the medicine: A, B group uses physiological saline 0.2ml/only (continuously to give medicine 14 days) every day, C group with 5 fluorine uracil mg/day, dilutes the density is mg/0.2ml (the 1~5th day for medicine), D group will put down with the physiological saline disappears the hitch to compound mg/only (continuously to give medicine 14 days).

依据随机化原则，将40只ICR雌性小鼠随机分为四组，分别为空白对照组，荷瘤对照组，5氟尿嘧啶组，平消栓组。B，C，D组每只小鼠右腋部皮下接种H22瘤细胞悬液0.2ml，接种24h后称重，并开始腹腔注射给药：A，B组每日用生理盐水0.2ml/只（连续给药14天），C组用5氟尿嘧啶25mg/kg（第1~5天给药），D组用生理盐水将平消栓配制成1.0g/kg（连续给药14天）。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
