Method convenience sampling selects 134 example later period lung cancer patient, after the chemotherapy, the white blood cell drops, needs the hypodermic injection to reorganize person granular cell colony stimulation factor .2011 year 6- in October to use the patient 70 examples which 1 ml injector injects to safety syringe for the control group, from November, 2011 uses the patient 64 examples to January, 2012 which the insulin injector injects to suppose for the observation group, the injection dosage is 200 μg, injects 3d, after continuously picks blood observation white blood cell (WBC) and the neutral granular cell (NE) value. Before finally the control group rises the blood pharmacological transfusion set, WBC and NE respectively be (2.64 ±0.62) ×109/L,(1.50±0.58)×109/L
