The clinical information gathering electronic template of Professor ZHANG Daizhao was established. Totally 145 cases of lung cancer were collected and the pattern types were determined to establish a medical record da- tabase. Qi stagnation blood stasis is the main pathogenesis

phlegm-damp-heat-toxin

yin deficiency and qi deficiency are the intermediate lesions and organ function imbalance is the initial pathologic basis of lung cancer according to the network diagram provided by the scale-free networks. The lung cancer patients were mainly with deficiency pattern and qi deficiency pattern
