Experimental: CMAB007 + Seretide/Symbicort + Ventolin
CMAB007(recombinant humanized anti-IgE monoclonal antibody for injection ) will be at a fixed dose determined by the subjects' total IgE and weight at V0. All the subjects will be treated subcutaneously for 24 weeks. The 4-week total dose is 0.016mg/kg/IgE(IU/ml), administered every 2 or 4 weeks, for the subjects with total IgE level 60-700IU/ml. If the total IgE level is 700-1500IU/ml, they will be administered 375mg every 2 weeks. Symbicort(Budesonide and formoterol fumarate powder for inhalation) or Seretide (salmeterol xinafoate and fluticasone propionate powder for inhalation) will be used 1/2 inhalations bid as asthma-controlled drug during the whole study. Ventolin (Salbutamol sulphate aerosol) will be used as asthma rescue drug.

- change from baseline in asthma symptom scores(daytime, nocturnal and total) over the 24-week treatment period [ Time Frame: from baseline(0 week) to 24 weeks ]mean asthma symptom scores(daytime, nocturnal and total): (pre-treatment - post-treatment)/pre-treatment *100%
- change from baseline in Asthma Control Test(ACT) over the 24-week treatment period [ Time Frame: from baseline(0 week) to 24 weeks ]ACT total score: (pre-treatment - post-treatment)/pre-treatment *100%
- change from baseline in Asthma Quality of Life Questionnaire(AQLQ) over the 24-week treatment period [ Time Frame: from baseline(0 week) to 24 weeks ]AQLQ total score and threshold score: (pre-treatment - post-treatment)/pre-treatment *100%
- investigator's and patient's Global Evaluation of Treatment Effectiveness(GETE) over 16 and 24-week treatment period [ Time Frame: from baseline(0 week) to 16 and 24 weeks ]GETE score at week 16 and 24
