Beta-Elemene is an antitumor drug which is isolated from the traditional Chinese medicinal herb Curcumae Phaeocaulis Rhizoma, it is the main component of elemene which is extracted from the plant and delivered via blood circulation after intravenous injection. The antitumor effect of beta-elemene in vitro and in vivo was definite, and beta-elemene could improve the patient immunity and no sever side effect, drug resistance or bone marrow suppression were found during the clinical studies. And human serum albumin (HSA) is a primary extracellular protein which has a high concentration distribution in blood plasma and has many characteristic physiological functions. Therefore, the binding of beta-elemene to protein may be very important for absorption, distribution, metabolism and elimination. Therefore, the study on the interaction of beta-elemene with drug-carrying protein is very important. In this work, molecular binding of beta-elemene to human serum albumin (HSA) was investigated by using spectrofluorometer. the binding constants suggested that a strong interaction and the formation of a complex between beta-elemene and HSA. This clearly implies that beta-elemene can be stored and removed by the proteins in the body. Furthermore, the fluorescence quenching results showed that the HSA fluorescence was quenched by beta-elemene through static quenching mechanism. Thermodynamic parameters showed that hydrophobic interactions play a role in the binding of beta-elemene to HSA. The negative deltaH(0) and positive deltaS(0) in case of beta-elemene therefore showed that electrostatic attraction play a role in the binding of beta-elemene to HSA.

To establish an HPLC-MS/MS method for the analysis of quercetin, kaempferid and isorhamnetin in rats plasma and study its pharmamacokinetics after an intragastrical administration of Hippophae rhamnoides extracts. Five healthy male Sprague-Dawley (SD) rats were given single doses of H. rhamnoides extracts (quercetin 26.35 mg x kg(-1), kaempferid 4.040 mg x kg(-1), isorhamnetin 31.37 mg x kg(-1)), and then their orbital sinus blood samples were collected at different time points. The drug plasma concentration of the three flavonoids was determined by HPLC-MS/MS method. After that, the main pharmacokinetics parameters were calculated by using Kinetica 5. 0. 11 software. The methodological test showed that the linear concentration ranges of quercetin, kaempferid and isorhamnetin were 7.500-600.0 μg x L(-1) (R2 = 0.998 5), 1.000-80.00 μg x L(-1) (R2 = 0.998 5 ) and 10.00-800.0 μg x L(-1) (R2 = 0.998 0), respectively. The inner and inter-days precisions were both less than 14.0%. The plasma samples showed a good stability and consistency with the requirement of biological sample analysis after the samples were frozen once and placed at - 20 degrees C for 15 d and room temperature for 6 h and the treated analytes were placed at -20 degrees C for 24 h. For quercetin, the pharmacokinetic parameter t(½β), AUC(0-∞), MRT(0.∞), C.(max) and T(max) were (113.3 ± 19.37) min, (12 542.14 ± 3 504.05) μg x h x L(-1), (119.6 ± 13.29) h, (164.6 ± 27.33) μg x L(-1) and (5.199 ± 0.840 3) h, respectively. For kaempferid, the pharmacokinetic parameters t(½β), AUC(0-t), MRT(0-∞), C(max) and T(max) were (79.85 ± 17.15) min, (934.51 ± 94.59) μg x h x L(-1), (81.50 ± 13.75) h, (80.15 ± 14.24) μg x L(-1) and (3.827 ± 0.902 7) h, respectively. For isorhamnetin, the pharmacokinetic parameters t1,2,, AUC(0-t), MRT(0-∞), C(max) and T(max) were (118.3 ± 20.73) min, (26 067.77 ± 4 124.60) μg x h x L(-1), (129.0 ± 16.30) h, (269.6 ± 29.32) μg x L(-1) and (6.513 ± 1.450) h, respectively. The HPLC-MS/MS analysis method established in this study was proved to be sensitive and accurate and could be applied in the pharmacokinetic study of quercetin, kaempferid and isorhamnetin in rat plasma.

OBJECTIVETo observe the effect of Kanli Granule (KG) on myocardial mechanics in pressure overload induced diastolic heart failure (DHF) rats.

METHODSTotally 60 male Wistar rats were divided into the sham-operation group, the model group, the KG group, and the Valsartan group according to random digit table, 15 in each group. The pressure overload induced DHF model was established in all groups except the sham-operation group using abdominal aortic constriction surgery. Totally 7 rats died after modeling (with the mortality of 10. 67%) , and the rest 53 finished the following test. Rats in the KG group were administered with KG extract (calculated as 6. 75 g crude drug/kg) by gastrogavage. Rats in the Valsartan group were administered with Valsartan (7.2 µg/g) by gastrogavage. Equal volume of double distilled water was administered to rats in the model group and the sham-operation group by gastrogavage. All rats were intervened for 32 weeks. The response of isolated heart papillary muscle tonus to isoprenaline (ISO) and adenylate cyclase (Forskolin) was respectively observed. The enhancement phenomenon after resting development force (DF) of isolated heart papillary muscle tonus, and changes of DF in different Ca²⁺ concentrations were observed.

RESULTS(1) In the ISO response test: Compared with the sham-operation group, the amplifications of DF, ±df/dt, -df/dt were obviously elevated in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously lowered in the KG group (P < 0.01), and the amplification of ±df/dt was also reduced in the Valsartan group (P < 0.01). (2) In the Forskolin response test: Compared with the sham-operation group, the amplifications of DF and ±df/dt obviously increased in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously reduced in the KG group (P < 0.01), and the amplification of DF was also reduced in the Valsartan group (P < 0.05). (3) In post-resting DF enhancement test: Compared with the sham-operation group, the amplification of DF showed gradually decreasing tendency along with prolonged resting time in the model group, and they were obviously lowered at all time points (P < 0.05). Compared with the model group, the amplification of DF was gradually increasing along with prolonged resting time in the KG group. The amplification of DF at post-resting 240 s was obviously larger in the KG group than in the model group (P < 0.05). The amplification of post-resting DF still showed gradually decreasing tendency along with prolonged resting time in the Valsartan group, with increased amplifications of DF at post-resting 60 s and 120 s (P < 0. 05) (4) The amplifications of DF in different Ca²⁺ concentrations: Compared with the sham-operation group, the amplifications of DF were significantly elevated in different Ca²⁺ concentrations (1.75, 3.5, 7.0 mmol/L ) (P < 0.05, P < 0.01). Compared with the model group, there was no statistical difference in amplification of DF in different Ca²⁺ concentrations in the KG group (P > 0.05). The amplifications of DF in different Ca²⁺ concentrations were significantly reduced in the Valsartan group (P < 0.05).

CONCLUSIONSThe ISO response and the Forskolin response were enhanced in isolated heart papillary muscle tonus of pressure overload induced DHF rats; enhanced post-resting DF was reduced; DF in different supra-physiologic levels of Ca²⁺ was still enhanced. KG could significantly improve excessive enhancement of pressure overload induced DHF rats in ISO response and Forskolin response, and improve enhancement of post-resting myocardium.
