ABSTRACT
Objective To observe the effects of sports with different strength combined with traditional Chinese medicine on expression of PGC-1α and function of vascular endothelium of IGT rats; To discuss the synergistic action and its mechanism.Methods Seventy healthy male SD rats were randomly divided into blank group (10 rats), which were given regular diet, and the other 60 rats were given high-glucose and high-lipoid diet to establish the IGT model rats, which were then randomly divided into 5 groups, including IGT model group (model group), simple Chinese medicine group (Chinese medicine group), low strength sports+Chinese medicine (low strength group), middle strength+Chinese medicine (middle strength group), and high strength sports+Chinese medicine groups (high strength group), 10 rats in each group. Rats in blank group, model group and Chinese medicine group exercised freely. While rats in different sport strength groups conducted treadmill exercise with different strength, and were givenDanzhi Jiangtang Capsules for gavage. Changes of NO, eNOS, vWF and EMP before and after the treatment were compared, the PGC-1α level was detected.Results Compared with the blank group, levels of NO, eNOS and PGC-1α decreased, while the levels of vWF and EMP increased in model group (P<0.05). Compared with the model group, levels of NO, eNOS and PGC-1α increased in all treatment groups, while the levels of vWF and EMP decreased (P<0.05,P<0.01). Conclusion Middle strength sports combined withDanzhi Jiangtang Capsules may effectively improve function of vascular endothelium.
