Objective: To develop and internally validate a nomogram to predict recurrence-free survival (RFS) including the time to radical cystectomy (RC) and perioperative blood transfusion (PBT) as potential ***: Patients who underwent open RC and ileal conduit between January 1996 to December 2016 were split into developing (n=948) and validating (n=237) cohorts. The time to radical cystectomy (TTC) was defined as the interval between the onset of symptoms and RC. The regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve ***: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were TTC (hazards ratio [HR] 1.07, 95% confidence interval [CI] 1.05-1.08, pmore units: HR 1.72, 95% CI 1.29-2.29, pmous cell carcinoma (HR 0.60, 95% CI 0.45-0.81, p=0.001), pT3-T4 (HR 1.77, 95% CI 1.41-2.22, pmph node status (HR 1.53, 95% CI 1.21-1.95, pmphovascular invasion (HR 1.28, 95% CI 1.01-1.62, p=0.044). The areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. The decision curve analysis revealed a better net benefit of the ***: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing TTC and PBT in addition to standard pathological criteria.

Band Gap Control for （Fe, Ti）-Containing mesoporous Silica Nanoparticles Using the Photo-Assisted Deposition Technique

引用

Journal of Environmental Science and Engineering 2010年第7期4卷 36-40页

作者： R.m. mohamed A.m. El-Toni F.A. harraz I.A. Ibrahim Advanced materials Technology Department Central Metallurgical Research and Development Institute （CMRDI） Helwan Cairo11421 Egypt

It is a great advantage to design advanced materials with outstanding porosity and controllable band gab. In this study, （Fe, Ti）-containing mesoporous silica （x Fe/Ti-HmS） nanoparticles were prepared by a photo-assisted deposition PAD technique, where x is a nominal composition ofFe （l to 4 wt%））. The prepared samples were characterized by DR-UV, XRD, and TEm techniques. The results showed the insertion of Fe into intra-framework of Ti-HmS resulted in a gradual narrowing of the band gap of Ti-HmS samples with increment of Fe wt%. TEm observations reveal that Fe nanoparticles are evenly distributed within Ti-HSm matrix at different Fe wt%. Such results indicate the possibility to control the band gap of a single-site photocatalyst （Ti-HmS） by coupling it with the conventional nano-sized Fe catalysts.

水力机械内的水压力脉动常常导致叶片的疲劳破坏及共振,为了研究叶片旋转交互作用引起的流体诱导水压力,基于CFD计算和模型试验开展导叶式喷水推进混流泵叶片交互作用径向力研究.建立了一个闭式的混流泵试验循环系统,在叶轮和泵轴内内置同步旋转测力计测量叶轮上的瞬时力和转矩.通过大量的标定确定试验轴系的动态特性.采用Fluent软件进行非定常数值模拟,并将模拟结果与试验结果进行了比较,分析了产生偏差的原因.结果表明:叶片旋转经过时的轴上径向作用力的频率与工况有关,同时叶片激发的径向力导致叶轮有与轴旋转方向相反旋转的趋势;计算的推进泵外特性与试验吻合较好,同时叶片交互作用径向力的量级也有较好的吻合度;从小流量到大流量工况,计算结果的变化趋势与试验结果一致.

世界核心医学期刊文摘（皮肤病学分册） 2005年第5期1卷 15-16页

作者： Luftl m. S■huler G. Jungbluth A.A. 牛新武 Department of Dermatology Universit y Hospital of Erlangen Hartmannstr. 14 D-91052 Erlangen Germany

Background:Cancer testis antigens (CTAs) are expressed in a variety of malign ant tumours. No CTA expression is found in normal adult tissues, except in male germ cells and occasionally placenta. To date, more than 20 CTAs or antigen fami lies have been identified. Objectives:Owing to their tumour-associated express ion pattern, CTAs may be useful for making a distinction between benign and mali gnant neoplasms. The present study was done to analyse the value of CTAs for the discrimination of cutaneous melanoma and naevi. Patients and methods:Primary m elanomas (38) and 19 naevi were analysed for their expression of CTAs by immunoh istochemistry using the following monoclonal antibodies (mAb) to the following a ntigens (mAb/antigen):mA454/mage.A1, 57B/mage.A4, ES121/NY-ESO-1. In a subs et of melanomas (n=26), the CTA panel was extended to three additional CTAs (mAb /antigen):CT7-33/mage.C1, m3H67/mage.A3 and GAGE/GAGE. Results:All 19 naevi were negative for the mAbs mA454, m3H67, 57B, ES121, CT7-33 and GAGE. In melan oma, the immunoreactivity was as follows:mA454:8/38 (21%), 57B 11/38 (29%), ES121 9/38 (24%). However, 19/38 (50%) were positive for at least one CTA. When 26 melanomas we re tested for the expression of six different CTAs 20/26 (77%) were positive fo r at least one CTA. Conclusions:CTAs may be useful in the determination of susp ected malignancy in cutaneous melanomas. The low incidence of particular CTAs ca n be overcome by increasing the number of CTAs analysed.

1962—1963年,在湘南、湖中、湘东和湘西等山区调查,得知湖南省水稻三化螟垂直分布最高为海拔1,025米。但不同山系的最高分布不一,一般都止于海拔800米以下。气候因素是影响垂直分布的主导因素。从湖南省三化螟的平面分布看来,它的踪迹遍及全省,但根据它们的发生动态,可划分为五个发生区:(1)第3—4代经常猖獗区:(2)第3—4代间歇猖獗区:(3)第3代经常猖獗区;(4)第3代间歇猖獗区:(5)轻微发生区。我们认为,水稻种植制度和气候条件是左右平面分布猖獗程度的因素。讨论了三化螟的预测预报和大田防治应有重点,在海拔700米以上地区,不必进行;400—700米的地区,视种植制度复杂与否来决定;400米以下地区,若双季稻或迟熟中稻面积较大,则必须着重进行。猖獗区要注意防治,轻微区要总结原因,找出根治螟害的途径。
