＜正＞In this paper an improved finite difference scheme is investigated to solve the equation of filtration type in porous textiles with phase change materials（PCM）,which can be expressed as a nonlinear source term. Due to the effects of source term,the constructed scheme is total variation bounded（TVB）.On the basis of this scheme thermal buffering effect of PCM is *** distributions of the temperature,saturated degree in the porous media with PCM were numerically computed by this *** the comparison the distributions of the temperature,saturated degree in the porous media without PCM were also numerically *** results indicate that this method is satisfactory.

BACKGROUND: Molecular cytogenetics of oncogene HER-2 amplification in primary hepatocellular carcinoma (HCC) is still unknown. The aim of this study was to in vestigate the frequency of HER-2 oncogene amplification in primary HCC and its relations to clinicopathological pa rameters and prognosis. METHODS: Forty-two surgical samples from patients with primary HCC were detected for their HER-2 oncogene am plification. The number of chromosome 17 and their ratio were tested by dual fluorescence in situ hybridization (FISH) technique, and then the correlations between HER-2 amplification, clinicopathological characteristics and prog nosis were analyzed statistically. RESULTS: HER-2 oncogene amplification was detected in 9 (21.4%) of the 42 primary HCCs, including 4 patient with high copy (HC) (9.5%) and 5 patients with low copy (LC) (11.9%). HER-2 amplification was associated signifi cantly with tumor size and postoperative survival time o HCC patients (P2 gene amplification was correlated with postoperative relapse (P— 0.257), but not related to sex, age, AFP level, HBV infec tion, histopathological grading and clinical staging of HCC patients (P>0.05). The HER-2 oncogene copy was exa mined in 31 (73.8%) of the 42 primary HCCs, consisting of 9 patients with HER-2 amplification (21.4%) and 22 pa tients with aneuploidy (52.4%). No significant relation were observed between the HER-2 oncogene copy, patien sex, tumor size, histopathological grading, clinical stag ing, postoperative relapse and survival time (P >0.05); bu the HER-2 oncogene copy was correlated significantly to age, AFP level and HBV infection (P 2 oncogene amplification and a higher frequency of chromo- some 17 aneuploidy in primary HCC. HER-2 oncogene amplification may be involved in the development and pro- gression of large HCC in some patients, and seems to be a valuably independent prognostic factor predicting the r
