Abstract:
ObjectiveTo observe the effects of five Huoxue Huayu prescriptions on blood lipid metabolism， liver tissue and adenosine triphosphate binding cassette transporter A1 （ABCA1） and peroxisome proliferator-activated receptor γ（PPARγ） expression in New Zealand rabbits with blood stasis syndrome， and to compare their differences in order to provide laboratory evidence for clinical selection of prescriptions and drugs. MethodSeventy New Zealand rabbits were randomly divided into normal group （n=10） and model group （n=60）. The blood stasis syndrome was modeled by the method of starvation+high-fat feed+adrenaline. After the models were successfully established， they were randomly divided into Xuefu Zhuyutang（3.55 g·kg-1·d-1） group， Danshenyin（1.962 g·kg-1·d-1） group， Shixiaosan（0.56 g·kg-1·d-1） group， Huoluo Xiaolingdan（2.80 g·kg-1·d-1） group， and Taohong Siwutang（2.66 g·kg-1·d-1） group， and were given corresponding compound prescriptions by gavage. The normal group and model group were given the same dose of distilled water. After the treatment of 30 consecutive days， blood was taken from the abdominal aorta to detect the content of total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol（LDL-C） and apolipoprotein A1 （ApoA1）. Hematoxylin-eosin（HE） staining was used to observe the changes in liver tissue. Real-time polymerase chain reaction （Real-time PCR） and Western blot were used to detect the mRNA and protein expression of ABCA1 and PPARγ in liver tissue， respectively. ResultCompared with the conditions in the normal group， increased mRNA and protein levels of HDL-C， LDL-C， TG， TC， and PPARγ （P<0.01）， decreased ApoA1 level （P<0.05） and decreased mRNA and protein levels of ABCA1 （P<0.01） were found in the model group. Compared with the conditions in the model group， the HDL-C level in the five Huoxue Huayu prescriptions was lowered （P<0.05）， and lowered TG level in Xuefu Zhuyutang group and Shixiaosan group （P<0.05）， decreased LDL-C and TC levels in Shixiaosan group （P<0.05）， and increased ApoA1 level in the Huoluo Xiaolingdan group （P<0.01） and Taohong Siwutang group （P<0.05） were observed. Furthermore， the mRNA and protein levels of ABCA1 in Xuefu Zhuyutang group， Shixiaosan group， Huoluo Xiaolingdan group and Taohong Siwutang group were elevated （P<0.05， P<0.01）， and the elevated levels were higher than that of Danshenyin group （P<0.05）. The mRNA level of PPARγ in the five Huoxue Huayu prescriptions was reduced （P<0.01）， and its protein level was also decreased in Xuefu Zhuyutang group， Shixiaosan group， Huoluo Xiaolingdan group and Taohong Siwutang group （P<0.01）. ConclusionThe five Huoxue Huayu prescriptions had a certain therapeutic effect on dyslipidemia，which might be achieved by up-regulating the expression of ApoA1 and ABCA1 to promote the production of HDL-C and strengthen the excretion of dysfunctional HDL-C. And Xuefu Zhuyutang had the optimal effect in lowering lipid.
