Objective: To explore the rules of Chinese patent medicines

western medicines

and their combination rules in the treatment of type 2 diabetes through data mining. Method: We queried and downloaded the data on type 2 diabetes from Sino Med on March

2011.By transferring semi-structured data structured database of Microsoft SQL was set into

we got the raw data for data mining. By executing the algorithm of discrete derivaties

we got some simple and meaningful networks of type 2 diabetes. In cytoscape

these networks were visualized. Result: In the treatment of type 2 diabetes

Chinese patent medicines

i.e.

Xiaoke Wan

Salvia Miltiorrhiza Injection

Radix Astragali Injection

Liuweidihuang Wan
