[Study of relationship between level of serum selenium and syndrome differentiation and typing of traditional Chinese medicine in lung cancer].

The relationship between the Syndrome differentiation and typing of TCM and the level of serum Se in the patients with the primary lung cancer was studied. The results revealed that the changed level of serum Se reflected the wax and wane of the pathogenic factors and body resistance in the patients with lung cancer. The level of serum Se gradually decreased as a result of the reducing body resistance and strengthening pathogenic factors, which suggested that it facilitated the evaluation of the patients' condition, recovery and prognosis of lung cancer. Due to the level of serum Se was lowered with the using of some chemotherapeutic agents, and through the treatment of lung cancer with the Syndrome Differentiation of TCM, it could supplement chemotherapy and maintain the serum Se level. It suggested that some Chinese medicinal herbs rich in Se should be selected to treat lung cancer so as to improve the therapeutic effect.
