Effects of Tongxinluo Capsules combined with routine treatment on Fib and MPV levels in appropriate patients for CABG surgery / 中成药

AIM To investigate the effects of Tongxinluo Capsules (Ginseng Radix et Rhizoma,Hirudo,Scorpio,etc.) combined with routine treatment on fibrinogen (Fib) and mean platelet volume (MPV) levels in appropriate patients for coronary artery bypass graft (CABG) surgery.METHODS One hundred and six patients were randomly assigned into control group (n =50) for routine treatment and observation group (n =56) for combination therapy of Tongxinluo Capsules and routine treatment.Both groups had their Fib and MPV levels evaluated,and safety compared.RESULTS Thirty,ninety days after the treatment,the two groups reported less incidence of composite cardiovascular events (refractory angina pectoris,relapsing myocardial infarction or death) (P ＜ 0.01),and the observation group had an even more obviously reduced plasma Fib level (P ＜0.01).The significantly decreased after-treatment MPV levels in the two groups were observed (P ＜ 0.05),and a most distinct decrease extent was found in the observation group after 90 d (P ＜ 0.05).For the bleeding events,the incidence rates of the observation group and the control group were 5.4％ and 4.0％,respectively.CONCLUSION For appropriate candidates of CABG surgery,Tongxinluo Capsules shows its efficacy in dissolving thrombus and improving clinical symptoms without serious bleeding risk.

Study on the Hemostatic Effect of Extracts from Herb Lamiophlomis rotata and Its Mechanism / 中药新药与临床药理

Objective To study the effect of Tibet medicine of Herba Lamiophlomis rotata on promoting hemostasis and blood coagulation and to explore its mechanism. Methods High dose(2 g/kg),middle dose(1 g/kg) and low dose (0.5 g/kg) of the aqueous extract from Herba Lamiophlomis rotata(HLRE)were given to mice by gastric gavage for 3 days,and then bleeding time (BT),clotting time(CT) and platelet count(PLC)were determined. Different doses of HLRE(3,1.5,0.75 g/kg)were administered by gastric gavage to rats for 14 days,and then blood samples were collected from common carotid artery for the determination of prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time(TT),fibrinogen(FIB),hepatic function and blood lipid indexes. Results Compared to the blank control group,the bleeding time and clotting time were obviously shortened in 2g/kg HLRE and 1g/kg HLRE groups and positive control group,but the difference of PLC was insignificant. PT and APTT values in all of the treatment groups did not differ from those in the blank control group. However, TT values were obviously shortened in 3 g/kg HLRE group,FIB and Albumen(Alb)values increased,the aminotransferase and blood lipid values tended to decrease. Conclusion The aqueous extract from Herba Lamiophlomis rotata has an effect on promoting hemostasis and blood coagulation ,and its mechanisms may be related to the increase of FIB and Alb contents and the shortening of TT value.
