Abstract:
Objective To observe the effects of curcumin on B-type natriuretic peptide (BNP),cardiac troponin Ⅰ (cTnI) and D-dimer in rats with acute pulmonary embolism (APE).Methods The irregular cbemotactic factor (CX3CL1)-shRNA and overexpression vector were designed and synthesized,and adenovirus packages were respectively carried out.Sixty Spargue-Dawley (SD) rats were divided into normal control group,sham-operation group,model group,curcumin group,curcumin+CX3CL1-shRNA group and curcumin+CX3CL1 overexpression vector group by random number table (each group 10 rats).The APE rat models were duplicated by autologous blood embolus method.in the pharmacological intervention groups,1 day and again 40 minutes before operation,a dose of curcumin 100 mg/kg was administered by gavage respectively;in virus intervention groups,3 days before modeling,intravenous injection of 109 pfu into a tail vein was performed once;in sham-operation group and model group,an equivalent dose of normal saline 2 mL daily was administered by gavage;the normal group did not accept any intervention.Six hours after modeling,the change of lung tissue were observed under confocal laser scanning microscope,the lung tissue was taken for hematoxylin-eosin (HE) staining,histopathological changes of lung tissue were observed,and the levels of serum BNP,cTnI,D-dimer were detected by enzyme-linked immunosorbent assay (ELISA).Results Virus infected lung tissue was green,nucler was blue.The HE staining in lung tissue showed:histopathological changes in the model group were more obvious than those in normal group and sham-operation group,after curcumin intervention,some emboli in pulmonary arteries in all treatment groups were partially dissolved,and the inflammation was alleviated.The results of ELISA shows:the contents of cTnI,BNP,D-dimer were significantly higher in model group than those in shamoperation group [cTnI (ng/L):224.97 ± 37.96 vs.149.13 ± 36.65,BNP (ng/L):53.66 ± 21.72 vs.24.62 ± 10.44,D-dimer (ng/L):78.68 ± 13.10 vs.42.00 ± 9.30,all P ＜ 0.05];the contents of cTnI,BNP,D-dimer were significantly lower in curcumin group,curcumin+shRNA group and curcumin+CX3CL1 overexpression vector group than those in model group (cTnI was 162.98 ± 28.65,143.32 ± 34.55,159.50 ± 37.80 vs.204.97 ± 37.96,all P ＜ 0.05,BNP was 27.45 ± 11.00,26.95 ± 6.66,33.05 ± 7.05 vs.53.66 ± 21.72,all P ＜ 0.05,D-dimer was 54.34 ± 4.57,53.38 ± 11.01,56.33 ± 6.80 vs.78.68 ± 13.10,all P ＜ 0.05);there were no statistical significant differences in comparisons among all intervention groups (all P ＞ 0.05).Conclusion Curcumin is able to improve serum BNP,cTnI,D-dimer in APE rats,but its relation with CX3CL1 is not obvious.
