We propose an efficient scheme to produce ultrahigh-brightness tens of MeV electron beams by designing a density-tailored plasma to induce a wakefield in the weakly nonlinear regime with a moderate laser energy of 120 *** this scheme,the second bucket of the wakefield can have a much lower phase velocity at the steep plasma density down-ramp than the first bucket and can be exploited to implement longitudinal electron injection at a lower laser intensity,leading to the generation of bright electron beams with ultralow emittance together with low energy ***-dimensional particle-in-cell simulations are carried out and demonstrate that high-quality electron beams with a peak energy of 50 MeV,ultralow emittance of28 nm rad,energy spread of 1%,charge of 4.4 pC,and short duration less than 5 fs can be obtained within a 1-mm-long tailored plasma density,resulting in an ultrahigh six-dimensional brightness B6D,n of2×1017 A/m2/0.1%.By changing the density parameters,tunable bright electron beams with peak energies ranging from 5 to 70 MeV,a small emittance of B0.1 mm mrad,and a low energy spread at a few-percent level can be *** bright MeV-class electron beams have a variety of potential applications,for example,as ultrafast electron probes for diffraction and imaging,in laboratory astrophysics,in coherent radiation source generation,and as injectors for GeV particle accelerators.

BACKGROUND: Giant cell carcinoma of the pancreas (GCCP) as a tumor of high malignancy, large size, and inflammatory reaction occupies 2.1%-12.8% of all cases of pancreatic malignancies. This study was to analyze cases of GCCP collected in 8 years at our hospital in an attempt to describe some features of GCCP in Chinese people. METHODS: The clinicopathological features of 19 patients who had been pathologically diagnosed as having GCCP from 1021 patients with pancreatic malignancies collected by Pancreatic Disease Research Group (PDRG) of Chang- hai Hospital were retrospectively analyzed compared with those of 96 patients with common pancreatic carcinoma (PC) who were randomly selected from 1002 patients with pancreatic carcinoma. The differences of location, clinical symptoms, imagings, laboratory test, operation and the prognosis of these two groups were defined. RESULTS: Tumors in the head of the pancreas were found in 8 patients (42.1%), and those in the body or tail of the pancreas in 11 (57.9%). The initial symptom was abdomi- nal pain in most patients (57.9%). Abdominal pain (73.7%), dyspepsia (63.2%), weight loss (36.8%) but jaun- dice were common at the time of diagnosis. The abnormal rates of routine laboratory tests in the GCCP group were lower than those in the common PC group. The assay of tumor markers between the groups of GCCP and common PC was approximately the same. The sensitivity and accu- racy of ultrasonography, spiral computed tomography and magnetic resonance imaging were considerably high. Large carcinoma in stage was seen in 9 patients or 47.4% of the GCCP group, a rate higher than that in the common PC group. Osteoid formation was found microscopically in some patients, and poorly differentiated tumor cells were found in most patients. The 1-year survival rate was 17.6%, which was lower than that in the common PC group. CONCLUSION: The clinicopathological features of GCCP are different from those of common PC. Imaging tests can be used tog

The effects of silybin on erythrocytic sorbitol level and peripheral nerve conduction veloci-ty were studied in 14 cases of noninsulin dependent diabetes mellitus (NIDDM) . Atter oral administrationof silybin 231 mglday for 4 weeks, no blood glucose change was observed in patients with NIDDM, whilethe erythrocytic sorbitol level was significantly decreased from 72. 55 21. 61 to 39. 53 14. 94 nmol/g .Hb (P<0. 01) . At the same time, peripheral nerve conduction vefocity was also improved. These resultsindicate that silybin is an effective aldose reductase inhibitor which can improve the disorder of polyolpathway in NIDDM patients and prevent chronic complications of diabetes.

根据27口井的镜质体反射率剖面,恢复了四川盆地早白垩世末—古新世时的古地温梯度.结果表明,古地温梯度介于20~25℃.km-1,总体呈南部略大于北部、东部大于西部的分布特征.根据古今地温梯度的对比,川西坳陷新生代早期以来地温梯度没有明显的变化,川东和川东北地区晚中生代以来地温梯度下降,而川中和川南地区晚中生代以来地温梯度升高.结合构造演化背景分析,盆地中新生代热历史主要受二叠纪末期的构造热事件、中生代晚期以来岩石圈厚度演化以及现今活动构造的影响.其中,二叠纪末期的构造热事件波及盆地大部分地区;现今活动构造对川南地区有明显的影响;中生代晚期以来的岩石圈厚度演化,可能是控制中新生代盆地大部分地区热历史的主要因素.
