Twenty-seven differential proteins were tested by MALDI-TOF-MS, 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, RNA-binding protein regulatory subunit and so on. By contrast, the levels of proteins such as PDX6, HSPA8 and MnSOD were significantly reduced in HCC patients.

The results of catalytic activity show that both Ni-B and Ni-P sample have the same kinetic equation for hydrogenation of 1, 3-cyclopentadiene to cyclopentene and the same TOF. Therefore, it can be suggested that they have the similar active site. The catalytic activity of Ni-B sample is higher than that of Ni-P sample, and it is due to the more active sites of Ni-B sample having.

催化活性测试表明，Ni-B与Ni-P催化环戊二烯加氢反应对环戊二烯具有相同的动力学方程，而且两者具有相似的氢转换频率，表明两者的活性中心本质上是相似的，类金属不同导致的电子转移方向的不同仅仅影响反应的初活性，宏观活性的差别在于两者活性中心数量的不同。

Based on the development of homogeneous gold complex catalyst, the polymer immobilized nano-gold catalyst was also prepared and used for oxidative carbonylation of amines or activation of carbon dioxide to carbamates and disubstituted ureas without addition of any co-catalyst and dehydration agents with greatly enhanced catalytic activity (TOF≈3000mol/mol/h).

同时，纳米金可以催化活化二氧化碳与脂肪族胺反应制备二取代脲，避免了传统上二氧化碳活化所大量使用的脱水剂，是当前文献报道最高效的胺与二氧化碳反应的催化剂体系（TOF≈3000mol/mol/h）。
