Objective To investigate the effects of different doses of propofor on ATP-sensitive K~+currents(I_KATP)in human atrial myocytes and the underlying mechsnism.Methods A small piece of myocardiumwas obtained from right atrium in patients undergoing atrial septal defect or ventricular septal defect surgery.Themyocardium specimen was placed in cold Ca~(2+)-free cardioplegic solution aerated with 100% oxygen.Themyocardium specimen was cut into small chunks(1 mm~3).Atrial myocytes were isolated by enzymatic dissociationtechnique.The effects of propofol on I_KATP in atrial myocytes were studied using the whole-cell configuration ofpatch-clamp technique.Results The outward currents were recorded with a pipitte solution containing 0.3mmol?L~(-1) ATP.The currents were inhibited by glibendamide 10 ?mol?L~(-1),a specific K_ATP channel inhibitor,suggesting that the outward currents were I_KATP.I_KATP aws activited by propofol in a dose-dependent manner.Conclusion Propefol can activate the I_KATP in human myocytes in a concentration-dependent manner and themechanism of its myocardial depressant action may be partly explained.

This paper aims to develop a method for the determination of aloe-emodin, rhein, chrysophanol and physcion and study the pharmacokinetic properties of four anthraquinones in rat plasma after oral administration of gardenia and rhubarb decoction. The plasma concentrations at different time points of four anthraquinones were determined by HPLC-FLD method. Plasma samples were extracted with liquid-liquid extraction procedure. Plasma samples were separated on a C18 column (4.6 mm x 150 mm, 5 μm), using 0.2% acetic acid and methanol as mobile phase at a flow rate of 1.0 mL min(-1) with gradient elution. The excitation and emission wavelengths were set at 430, 525 nm, respectively. DAS 2.0 software was applied to calculate the pharmacokinetic parameters. The results showed four anthraquinones can be absorbed. The main parameters of aloe-emodin, rhein, chrysophanol and physcion were as follows: C(max) for aloe-emodin was (0.085 ± 0.058), (3.772 ± 1.152), (0.464 ± 0.267), (0.028 ± 0.008) mg x L(-1) respectively; t(max) for rhein was (1.042 ± 0.510), (0.805 ± 0.307), (1.167 ± 0.283), (0.616 ± 0.162) h respectively; t½ for chrysophanol was (3.557 ± 1.250), (6.879 ± 1.126), (5.196 ± 2.032), (4.337 ± 1.816) h; AUC(0-t) for physcion was (0.504 ± 0.130), (9.558 ± 1.106), (2.545 ± 1.554), (0.052 ± 0.018) mg x h x L(-1). This paper developed a selective, accurate and sensitive HPLC-FLD method for the simultaneous determination of four anthraquiones in rat plasma.

Conclusion The thera-pists satisfied in the training, that may improve the ability of therapists to contribute to their organization.

OBJECTIVE: The objective of this study was to evaluate the effect of nasal packing, septal suture technique and vacuum sealing drainage (VSD) after septoplasty. METHOD: Ninety patients of nasal septal deviation in Combination with outfracture of the inferior turbinates who had received septoplasty were selected in this study. The patients were allocated into three groups, with thirty in each: for packing group, marcel materials were used for nasal packing after septoplasty; for suturing group, septal suture technique was performed after septoplasty; for VSD group, one drainage tube was used for negative pressure sucking after septoplasty without nasal packing. Postoperative signs and symptoms were compared between three groups. The comfort degree assessment included headache and nasal obstruction were evaluated by using visual analogue scale (VAS) at the 12th hour and 24 hour after operation. The edema in nasal cavity, hemorrhage. abscess,adhesive and healing rates after operation were compared among three groups. RESULT: The VAS score of headache and nasal obstruction and the severity of patient's conditions were significantly less in septal suture group and VSD group than that in packing group at the 12th and 24th hour after operation. The mucosa edema of nasal cavity was significantly slighter in septal suture group and VSD group than that in packing group at the third day after operation. The healing rates and number of complications are better in septal suture group and VSD group than those in packing group at the 7th day after operation. There were no hemorrhage or abscess in VSD group. CONCLUSION Septal suture technique and VSD after septoplasty can significantly relieve the distress of patients and reduce the healing time of mucosa in nasal cavity without increasing the risk of complications.
