2CT arterial portography and CT hepatic arteriography in detection of micro liver cancer显示文摘AIM To recognize the characteristic findings of micrQliver cancer (MLC) and to evaluate the effect of CT arterial portography (CTAP) and CT hepatic arteriography (CTHA) in diagnosis of MLC. METHODS Between April 1996 to December 1998, CTAP and CTHA were performed in 12patients with MLC, which were not detect ed byconventional CT examinations. After CTHA, 3 mL-- 5 mL mixture of lipiodol, doxorubic in andmitomycin C were injected into hepatic arterythrough the catheter, and then followed up by CTthree or four weeks later (Lipiodol CT LP-CT).RESULTS A total of 22 micro--tumors (0 .2 cm 0.6 cm in diameter ) were detected in 12patients, which manifested as small perfusiondefects in CTAP and small round enhancement inCTHA. The rate of detectability of CTAP andCTHA was 68.2% (15/ 22) and 77.3% (17/ 22)respectively, and the rate of the simultaneoususe of both procedures reached 86. 4% (19/ 22 ).All micro--tumors were demonstrated as punctatelipiodol deposit fool in LP--CT. After LP--CT, theelevated serum level of Q-fetoprotein (AFP)dropped to the normal level in all patients.CONCLUSION The CTAP and CTHA are the mostsensitive imaging methods for detecting microIiver cancer. Confirmed by the change of theelevated serum AFP level and lipiodol depositfool in LP-CT, small perfusion defects in CTAPand punctate enhancement in CTHA may suggestmicro--liver cancer.Li L Wu PH Mo YX Lin HG Zheng L Li JQ Lu LX Ruan CM Chen L 1999World Journal of Gastroenterology1999,5,3:16

5乙型肝炎病毒与肿瘤抑制基因p53相互作用的生物学功能及意义显示文摘以前的研究发现:HBVX蛋白能与肿瘤抑制基因p53蛋白结合,在原发性肝癌的发生中具有重要意义。为进一步探讨二者之间的关系,经过计算机比较分析发现,在HBV基因组中存在与经典的p53DNA-蛋白质结合位点类似的序列(TGCCT),用含有此序列的HBV基因片段作探针,与肝癌细胞核蛋白作用,通过凝胶电泳迁移率移位实验、凝胶电泳迁移率超移位实验和原位紫外线交联实验,确定其HBVDNA与p53蛋白的特异性结合;进一步用p53与HBVDNA共转染和定量PCR分析,探讨二者结合对HBVDNA复制的影响和意义。结果显示,HBV基因组中存在能与p53蛋白特异性结合的序列,使细胞内p53蛋白积聚,并反式激活,增强HBVDNA的复制。这一结果对进一步揭示HBV感染与原发性肝癌发生的关系。朱明华 Duan.,LX 1998病毒学报1998,14,1:11
6Isolation and Structure Elucidation of Autolytimycin, A New Compound Produced by Streptomyces Autolyticus JX-47显示文摘Autolytimycin 1 was isolated from the culture filtrate of Streptomyces autolyticus JX-47, together with two known compounds, lebstatin 2 and 17-O-demethyl-geldanamycin 3. These compounds showed the activities of anti-HSV-I. The structure of 1 was determined by spectral analysis.Li, MG Wu, SH Zhao, LX Zhang, Q Li, WJ Cui, XL Xu, LH Wu, DG Jiang, CL 2001Chinese Chemical Letters2001,12,10:10
7Clinical significance and pathogenic role of anti-cardiac myosin autoantibody in dilated cardiomyopathy显示文摘In order to explore the possible roles played by the autoimmune mechanism in the progression of myocarditis into dilated cardiomyopathy (DCM) using an animal model, we investigated whether autoimmune myocarditis might develop into DCM Methods Experimental Balb/C mice (n=20) were immunized with cardiac myosin with Freun d’s complete adjuvant at days 0, 7 and 30 The control Balb/C mice (n=10) were immunized with Freund’s complete adjuvant in the same mannere Serum and my ocardium samples were collected after the first immunization at days 15, 21 and 120 The anti-myosin antibody was examined by enzyme-linked immunosorbent assay and immunoblotting Results Pathological findings demonstrated that there was myocardial necrosis or inflammatory infiltration during acute stages and fibrosis mainly in the late phase of experimental group, but the myocardial lesions were not found in the control group Autoimmunity could induce myocarditis and DCM in the absence of viral infection High titer anti-myosin IgG antibodies were found in the experimental group, but not in the control group Furthermore, the anti-myosin heavy chain (200 KD) antibody was positive in 21 of 48 patients with DCM and viral myocarditis, but only 4 of 20 patients with coronary heart disease, including 1 case and 3 c ases that reacted with heavy and light chains (27 5 KD), respectively The antibodies were not detected in healthy donors Conclusion Cardiac myosin might be an autoantigen that provokes autoimmunity and leads to the transformation of myocarditis into DCM Detection of anti-myosin heavy chain antibody might contribute to diagnosis for DCM and viral汪朝晖 廖玉华 董继华 李淑莉 王金平 Michael LX Fu 2003Chinese Medical Journal2003,,4:8

9Mechanism of frost heave by film water migration under temperature gradient显示文摘IT is well known that there exists unfrozen film water in frozen soils due to the action of sur-face energy among soil particles and frost heave occurs by water migration under the tempera-ture gradient. The problem is how to determine the amount of frost heave quantitatively. The amount of frost heave induced by ice segregation can be calculated by the following e-quations:Xu, XZ Wang, JC Zhang, LX Deng, YS Chuvilin, EM Yershov, ED Ishizaki, T Fukuda, M 1997Chinese Science Bulletin1997,42,15:6

11Phase Evolution during the Sintering of Submicron Ti(C,N)-Based Cermets显示文摘The submicron powder mixtures of TiC-TiN-WC-Mo-C-Ni sintered at 1400℃ or below in vacuum were studied by X-ray diffration (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses. The results showed that Mo2C fOrmed at 800℃ or below. Both WC and Mo2C disappeared at 1200 ℃, and TiN disappeared at 1250℃. In addihon, the variahons of lanice constans of the htanium carbonitride and nickel binder phase with sintering temperature were experimentally obtained, and the reason was analyzed.Li, CH Xiong, WH Yu, LX 2001Rare Metals2001,20,4:4

13Static Adsorption of Xenon on ACF at 257 K显示文摘The static adsorption of xenon on active carbon fiber (ACF) at 257 K was measured with ASAP2010 specific surface area and pore diameter distribution instrument by changing the working gas from nitrogen to xenon. Compared with grain activated carbon (GAC), the results were as follows: (1) The adsorption performance of Viscose-based ACF (VACF-As) was the best among all absorbents tested. VACF-A3 was the superior xenon absorbent. The performance of pitch-based ACF (PACF-Cs) approached that of GAC, (2) Due to the difference of aperture distribution, the adsorption performances of ACF with different radics were different under the same experiment conditions even though the specific surface area was similar, (3) There were some differences of adsorptive capacity among ACF absorbents which had the same radic, however there was not definite relationship between their specific surface area and adsorptive capacity, (4) The adsorption of xenon on all kinds of ACF agrees with Langmuir equation, (5) The adsorptive curves can be fitted with a binomial equation.Zhang, HT Wang, YL Wang, XH Zhang, LX Chen, LY 2002Journal of Materials Science & Technology2002,18,6:3
