Objective To explore an effective methods for percutaneous biopsy needle fixing which is guided by CT.Methods After the biopsy needle gets to the destination along with the aforehand route,the unique designs of hollow cylinder and the strip can fix the biopsy needle effectively.

在CT导引下，经皮穿刺切割活检术中，活检针沿预置路径进入靶点后，再经CT扫描确定活检针位置及深度是否准确，通常的方法是嘱患者家属或医务人员用手扶住活检针的控制部。

The free volume cell theory was applied to derivative the formula of activity coefficients of liquid binary solution at arbitrary temperature. The Monte Carlo algorithm was employed to calculate the non-liner equations, then the free volume parameters were directly correlated to the activity coefficients of liquid binary, ternary, quaternary and quinary solutions at arbitrary temperature. The three dimensional diagrams of a-x-T diagrams representing the changes of activity with those of temperature and concentration were plotted.

由自由体积胞腔理论推证了某温度下两组分的活度系数关联式；引入MonteCarlo非线性方程解法，通过无限稀释溶液的实验活度系数数据直接得到自由体积参数和二元系及多元系液态金属溶液在任意温度下全浓度范围内的活度数据，构筑了直观反映活度随温度和浓度变化的a-x-T三维图形。

Progress in research of catalyst deactivation in ethylbenzene dehydrogenation was reviewed.Active phase of the catalyst was briefly analyzed.Five main reasons for the catalyst deactivation were discussed,including coke deposition,loss and redistribution of potassium promoter,change in oxidation state of iron,structural transformation of the catalyst,and the catalyst poisoning.

对乙苯脱氢制苯乙烯催化剂失活的研究进展进行了综述，分析了催化剂的活性相，分别探讨了积碳、钾的流失与重新分布、Fe3+的还原、催化剂物理结构的变化和中毒等5个因素对催化剂失活的影响及其失活机理，其中，钾的流失和Fe3+的还原是造成催化剂失活的重要因素。

Most (14 out of 17, 82%) duodenal biopsies showed apoptotic counts of ≥2/100 crypts, 28%(5 out of 18) of gastric biopsies showed apoptotic counts of ≥3/100 glands, and 57%(4 out of 7) of esophageal biopsies showed apoptotic counts of ≥2/10 high-power field. Four gastric biopsies showed a previously undescribed injury pattern of parietal cells resembling the ballooning degeneration.

大多数十二指肠活检（17例中有14例，82%）的细胞凋亡计数为≥2个/100个隐窝，28%胃活检（18例中有5例）的凋亡计数为≥3个/100个腺体，57%食管活检（7例中有4例）的凋亡计数为≥2个/10个高倍视野。4例胃活检的壁细胞出现了一种以往不曾认识的损失模式——酷似气球样变性。

It is better to live significantly for 30 years than to live meaninglessly for 100 years.

我想活的有意义活着有价值三十岁就够了，活的没意义没价值到了一百岁也是白活了。

The results showed that the purity of the pectinase was improved about 41.2 times, the purity of the xylanse was improved about 18.3 times.

结果表明：果胶酶1的比活是发酵液中该酶比活的41.2倍，木聚糖酶的比活是发酵液中该酶比活的18.3倍。

objective to evaluate the main points and complications of ct-guided percutaneous pneumocentesis in patients with lung lesions.methods cook 18～21g puncture needle was used to inserting aspiration in the optimal level,situs,angle and depth.and had made of multidrop.fifty-nine patients with lung lesions underwent ct-guided percutaneous pneumocentesis and follow-up.results the successful puncture rate was 100%,accurate diagnose rate was 92%(54/59).conclusion ct-guided pneumocentesis for chest lesion is a efficient and safe diagnostic method.but it is important to improve the doctor′s operating skill to lessen vascular complication.

目的 探讨ct引导下经皮肺穿刺活检的技术要点及并发症。方法采用cook公司18～21g自动弹射活检枪，选择最佳层面、进针点、进针角度和深度，行多点取材。回顾性分析59例肺内病变ct引导下经皮肺穿刺活检术。结果穿刺成功率100%，活检诊断准确率为92%（54/59）。3例发生轻度气胸，2例穿刺后咯血痰。结论 ct引导下经皮肺穿刺活检术成功率高，是安全的，但操作医生熟练的技术方法非常重要，并可以减少并发症的发生。

But today, three minutes, we cried, we cried the whole land of mountains and rivers touching it, over the entire Chinese nation and uniting the strength of the grief and indignation, we no longer need to suppress the sentiments in mind, no longer need to control in the past few days in Yanquan Dazhuan tears, street car on a collective whistle, sounding the alarm over the city, a city of Wu Yan, it is also crying, cry on Kuba, we have too many needs to suppress the release, cry on Kuba, We have too many depressing need venting, 3 minutes, we do not want to do what, we just cry, as we are brothers and sisters toward heaven, for those who are strong to survive the hand-foot-compatriots.

破碎的心，往往会变得相当脆弱，灾后重建，坚强就变得尤其重要，三分钟过后，我们要擦干眼泪，我们不能再哭，要勇敢地活下去，因为亲人会在天堂看着我们，痛不欲生、伤心欲诀不是他们想看到的，好地地活下去，是他们对我们的期望，想一想，那废墟中以已命换子命的母亲，&亲爱的宝贝，如果你能活下去，要记住，妈妈爱你&；想一想那为了救四个孩子而牺牲了的老师，我们的走了的这些亲人，用自己的生命给我们争来了活的机会，为了他们，我们也要活的更好。

Just as Premier Wen said the sentence, as you live, to live well, not only Premier Wens expectations, even tens of thousands of brothers and sisters of our expectations, think about all those days and nights in Disaster areas the army for help, from the ruins of their hand to you to save 1.1 points out of the broken hand, the bloodshed, they moved the hands of tile brick shift has not stopped, they run the risk of aftershocks at any time to And the death race, is to allow more people to live, so that the good live, not only for ourselves, but also to all the people we love, good living, is our responsibility as well as your Obligations.

就像温总理说的那句话，你们既然活下来了，就要好好活，这不仅仅是温总理的期望，更是成千上万的手足兄弟对我们的期望，想一想那些不分昼夜在灾区求援的子弟兵，他们从废墟中用手一点一点把你们救了出来，手破了、流血了，可他们搬砖移瓦的手却一直没有停，他们冒着随时都有余震的危险来和死神赛跑，为的就是能让更多的人活下来，所以说，好好活下去，不只是为了我们自己，更是为了这一切爱我们的人，好好活，是我们的责任，也是你们的义务。

Then the analyses of detected results and the TNM stagings or the histological classifications of the carcinoma were statistically analyzed in SPSS.

结果：p53功能失活率为64％，明显高于p53基因突变率49％。p53功能失活和食管鳞癌的TNM分期有关，分期越高，p53功能失活率越高；p53功能失活和食管鳞癌的组织学分级有关，分级越高，p53功能失活率越高。
