The particle size of the dispersed gel synthesized under lower HPAM concentration increases with the concentration of HPAM or AlCA, but does not change evidently on addition of NaCl, Which shows the good salt tolerance property of dispersed gel.

在较高HPAM浓度下形成的连续网状凝胶，只有在／为最佳配比条件下才能获得最大的强度；在较低HPAM浓度下形成的分散凝胶，其粒径随HPAM或AlCA浓度增加而增大。

The gel (600mg/L HPAM, 50mg/L AlCA) keeps its complex viscosity as about 400mPa·s when aged at 50℃ for 2 months, which indicate that HPAM-AlCA weak gel is suitable for application in middle temperature and has excellent properties and low cost.

HPAM—AlCA凝胶在80℃下老化时，其强度将迅速下降，在50℃老化时仍可保持良好的交联效果，组成为600mg／L HPAM+50mg／L AlCA+1.5％NaCl的凝胶经50℃老化2个月后，复粘度达近400mPa·s。

Methods: During the April 2003 to December 2004, from the patients with different position colorectal cancer beyond Dukes C stage who were performed laparoscopic radical operation random draw 20 patients as experiment group, and from patients with different position colorectal cancer beyond Dukes C patients who were performed open radical operation 20 patients took randomly as contrast group. We draw thepatients blood about 5 ml from antecubital vein at the time before and after the operation about 30 minutes respectively, preserved the blood in deep hypothermia circumstance,cytrokeratin-20(CK-20) as the micrometastasis maker, using the RT-PCR technique,G3PDH as the intra-contrast gene, quantitatively detect the amounts of CK-20 in the blood with the gelatum imagery system and the computer analyzing software on the gelatum imagery system ,in order to compare the influence of the laparoscopic and the open operation on the micrometastasis.

RESULTS: A well-resolved and reproducible 2-DE pattern of PBMC was obtained from patients with HBV associated HCC or LC. For HCC, the mean number of protein spots was 1186±43, with an average matching rate of 91.6%, and for LC, the mean number of protein spots was 1013±41, with an average matching rate of 90.2%. Twenty-seven differential proteins were tested by MALDI-TOFMS, and 16 were identified. Of the 16 proteins, 13 were up-regulated in patients with HCC, including heat-shock protein 27, member RAS oncogene family (RAB14), actin, alpha 1 antitrypsin, RNAbinding protein regulatory subunit and so on. By contrast, the levels of proteins such as PDX6, HSPA8 and MnSOD were significantly reduced in HCC patients.
