OBJECTIVETo assess the role of vanilloid receptor (VR) in thermal hyperalgesia induced by intraplantar endothelin-1 (ET-1) injection.
METHODSVR gene-knockout mice (KO group) and wild type C57BL/6J mice (WT group) in 3 subgroups were subjected to intraplantar administration of ET-1 at the doses of 3, 10, 30 and 100 pmol (dissolved in 10 microl of PBS, pH 7.4, n=6 in each group), respectively. The latency time of paw withdrawal (PWT) from heat irradiation stimulation was recorded before injection and 15, 30, 45 and 60 min after injection.
RESULTSET-1 induced thermal hyperalgesia in both groups. The mice in WT group showed a more sharply shortened PWT than those in KO group. ET-1 decreased PWT as the dose administered increased in WT group, which was different from the responses of the KO mice. At the dose of 100 pmol of ET-1, no further decrement of latency time was observed in WT group, whereas such response occurred at 30 pmol in KO group.
CONCLUSIONIntraplantar injection of ET-1 induces thermal hyperalgesia mediated partially by VR.

To investigate the effect of Jiawei Foshou San and its various combined administration on hepatic P450 enzyme activity and hepatocyte morphology in rats. Rats were orally administered with drugs for four weeks and then sacrificed to prepare liver microsomes. The liver microsomes were incubated with the cocktail method; The metabolites were determined with the rapid liquid chromatography with tandem mass spectrometry (LC-MS/MS) to investigate the hepatocyte P450 enzyme activity. In addition, the hepatic pathological changes were observed by using the hematoxylin and eosin (HE) staining. Compared with the control group, the enzyme activity of CYP1A2 and CYP3A4 in the Jiawei Foshou san group showed a significant rise (P < 0.05); the enzyme activity of CYP1A2, CYP2C9, CYP2D6, CYP2E1 and CYP3A4 in the ferulic acid + ligustrazine group and the ligustrazine + tetrahydropalmatine group showed a significant rise (P < 0.05) ; the enzyme activity of CYP1A2, CYP2D6 and CYP2E1 in the ligustrazine group showed a significant rise (P < 0.05); the enzyme activity of CYP3A4 in the ferulic acid group showed a significant reduction (P < 0.05). After the administration with various drugs, the hepatocyte morphologies in the ferulic acid group and the ligustrazine group were normal. The pathological changes were observed in the tetrahydropalmatine group, such as unclear boundary of hepatic lobules, disordered hepatic cell arrangement, blurred edge, anisokaryosis and infiltration of inflammatory cells. The ferulic acid + tetrahydropalmatine group, the ligustrazine + tetrahydropalmatine group and the Jiawei Foshou San group also showed inflammatory infiltration, but with less pathological changes, particularly the Jiawei Foshou San group. The study result shows that Jiawei Foshou San can induce the enzyme activity of CYP1A2 and CYP3A4, and ligustrazine may be the effective substance for inducing CYP1A2. Its combination with ferulic acid and ligustrazine can significantly reduce the liver toxicity of tetrahydropalmatine.

OBJECTIVETo evaluate perioperative occult blood loss following total knee arthroplasty (TKA).
METHODSA retrospective analysis of 40 patients undergoing TKA was conducted to calculate the mean blood loss and occult blood loss according to Gross formula.
RESULTSThe mean total blood loss was 1538 ml in these cases with occult blood loss of 791 ml. In patients with autologous blood transfusion, the mean total blood loss was 1650 ml with occult blood loss of 786 ml. In patients without autologous blood transfusion, the mean total blood loss was 1370 ml with occult loss of 798 ml.
CONCLUSIONTKA often results in large volume of occult blood loss in the perioperative period which can not be fully compensated by autologous blood transfusion, and additional blood supply is needed for maintenance of the circulating volume.

OBJECTIVETo investigate the effect of the mammalian target of rapamycin (mTOR) inhibitor CCI-779 on the chemosensitivity of androgen-independent prostate cancer cell line PC-3.
METHODSProstate cancer cells PC-3 were cultured and treated with CCI-779, Paclitaxel and combination of the two. Then the inhibitory effects of the three medications on the growth of the PC-3 cells were determined by MTT, and the their cell cycle and apoptosis were detected by flow cytometry.
RESULTSCompared with the control group, the three medications all significantly inhibited the proliferation of the PC-3 cells, and the combined method even enhanced the effect. Flow cytometry showed that CCI-779 and Paclitaxel blocked the cell cycle mainly in the G1/G2 stage, while the combined medication mainly in the G0/G1 stage. Significantly increased apoptosis of the PC-3 cells was observed in the three medication groups as compared with the control group (P < 0.01).
CONCLUSIONCCI-779 can inhibit the proliferation of PC-3 cells and enhance the chemosensitivity of prostate cancer.

OBJECTIVETo observe the effects of combined treatment with sansanmycin and macrolides on Pseudomonas aeruginosa and formation of biofilm.
METHODSMicro-dilution method was used to determine the minimal inhibitory concentrations (MICs) of sansanmycin, gentamycin, carbenicillin, polymyxin B, roxithromycin, piperacillin, and tazobactam. PA1 and PA27853 biofilms were observed under optical microscope after staining and under SEM after treatment with sansanmycin at different dosages and combined treatment with sansanmycin and roxithromycin. Viable bacteria in PA1 and PA27853 biofilms were counted after treatment with sansanmycin at different dosages or combined treatment with sansanmycin and roxithromycin.
RESULTSThe MIC of sansanmycin was lower than that of gentamycin and polymyxin B, but was higher than that of carbenicillin. Roxithromycin enhanced the penetration of sansanmycin to PA1 and PA27853 strains through biofilms. PA1 and PA27853 biofilms were gradually cleared with the increased dosages of sansanmycin or with the combined sansanmycin and roxithromycin.
CONCLUSIONSub-MIC levels of roxithromycin and sansanmycin substantially inhibit the generation of biofilms and proliferation of bacteria. Therefore, combined antibiotics can be used in treatment of intractable bacterial infection.

Investigation of the pharmacokinetics of paeonol microemulsion, microemulsion-based gels and marketed paeonol ointments by the skin-blood synchronous microdialysis coupled with LC/MS is reported in this study. The microdialysis systems were established by linear probes and concentric circles probes. In vivo recovery of paeonol in skin is (69.7 +/- 4.8) % and in blood is (51.6 +/- 7.2)%. The paeonol microemulsion, microemulsion-based gels and marketed paeonol ointments were administered to rats. PBS (pH 7.4) served as perfused solution. The perfusion rate was 5 microL x mL(-1) and the microdialysis samples were collected every 20 min intervals. The paeonol concentration in perfused solution was determined by LC/MS. The results showed that paeonol microemulsion and microemulsion-based gels significantly raised the drug concentrations in skin more than that of paeonol ointments. The paeonol microemulsion-based gels has similar bioavailability as the paeonol ointments in blood, but its blood drug concentrations were steadier. The paeonol microemulsion-based gels may be developed into a new preparation for dermis eczema. The skin-blood synchronous microdialysis technique proved to be a new method for the pharmacokinetics study of transdermal delivery systems.
