Drop of TG and TC levels were inconspicuous of the intervention group (P<0.1), but marked of the integrative group (P<0.05~P<0.001). TG level dropped mildly (P<0.1), while TC level was significantly down (P<0.05) of the biomedicine group.Conclusion:life style intervention, Spleen Fortifying and Blood Reduction Granules and deltamine can lower BS level of IGT patients.
