Aims Tocomparethepharmacokineticsof ephedra alkaloids,cinnamic acid and cinnamic alcohol in Ephedrae, Cinnamomi and Ephedrae-Cinnamomi herb couple through UPLC-MS/MS in rats respective-ly,and to investigate the effect of combination on phys-iologicaldisposition.Methods Plasmasampleswere collected at different times after oral administration of Ephedrae,Cinnamomi and Ephedrae-Cinnamomi herb couple extracts.The concentrations of ephedra alka-loids,cinnamic acid and cinnamic alcohol in plasma samples were determined by UPLC-MS/MS.DAS 3. 0 was used to calculate pharmacokinetic parameters.The differences of samples in two groups were conducted with univariate statistical analysis using SPSS 13. 0. Results ComparedwithEphedraegroup,theCmaxof norephedrine hydrochloride, norpseudoephedrine hydrochloride,ephedrine hydrochloride,pseudoephed-rine hydrochloride,and methylephedrine hydrochloride in Ephedrae-Cinnamomi herb couple group were signif-icantly greater (P<0. 05 );the AUC0-t of norpseudo-ephedrine hydrochloride was significantly greater (P<0. 05 );the MRT0-t of norephedrine hydrochloride, phedrine hydrochloride, pseudoephedrine hydrochlo-ride,and methylephedrine hydrochloride were signifi-cantly less (P <0. 05 );the T1/2z of norephedrine hydrochloride,phedrine hydrochloride,and methyl-ephedrine hydrochloride were significantly less (P <0. 05 ).The AUC0-t and MRT0-t of cinnamic acid and cinnamic alcohol were significantly greater than those inCinnamomigroup(P<0.05).Conclusion The combination of Ephedrae and Cinnamomi improves the absorption concentration of five ephedra alkaloids, Slows down the elimination of norephedrine hydrochlo-ride,phedrine hydrochloride,pseudoephedrine hydro-chloride,and methylephedrine hydrochloride,and in-creases the bioavailability of cinnamic acid and cin-namic alcohol.

Objective To examine the neuroprotective effect of pulsed magnetic field in a animal focal cere-bral ischemica-reperfusion injury model. Methods Forty-eight Sprague-Dawley (SD) rats were randomized into 3 groups, a sham-operation group, a model group and a pulsed magnetic field group, with rats 16 in each group. Mid-dle cerebral artery occlusion (MCAO) method was employed to establish the focal cerebral ischemia-reperfusion inju-ry model in rats of model group and pulsed magnetic field group. Rats in sham-operation group was subject to the same operation procedure but not underwent ischemia-reperfusion. The infarction volume, histopathological damage and expressions of IGF-1 in ischemic brain tissue were investigated to evaluate the effect of pulsed magnetic field. Results The infarction volume was reduced, histopathological damage alleviated and expressions of IGF-1 in ische-mic brain tissue elevated in the pulsed magnetic field group as compared against the model group (P<0.05). Con-clusions Pulsed magnetic field might provide neuro-protection against cerebral ischemia-reperfusion injury.

Objective To compare the impact of propofol and sevoflurane on thermoregulation in children undergoing orheopaedic surgery.Methods Sixty-eight children scheduled to undergo ortho-paedic surgery were randomly allocated to receive propofol (group P)and sevoflurane(group S)anes-thesia,34 cases in each group.Tympanic temperature was recorded 5 minutes before (T0 )and 5 min (T1 ),1 5 min (T2 ),30 min (T3 ),45 min (T4 ),60 min (T5 ),75 min (T6 ),90 min (T7 ),105 min (T8 )and 120 min (T9 )after anesthesia.Total fluid intake,duration of surgery,duration of anesthe-sia,the incidence of hypothermia,and the incidence of shivering were also recorded.Results Com-pared with T0 ,in both groups body temperature declined at T1-T8 .There was no difference between the two groups in total fluid intake,duration of surgery,duration of anesthesia and the incidence of shivering.Compared with group P,children in group S had a higher incidence of hypothermia(8 vs 1). Children in group S had lower temperature,which had statistical significance at T7 and T8 (P <0.05). Conclusion The core temperature of children undergoing orthopaedic surgery showed a trend of in-crease after the first fall in the surgery.Compared with propofol,sevoflurane anesthesia is more likely to lead to the incidence of hypothermia in children undergoing orthopaedic surgery in 90 min after in-duction of anesthesia.

Objective To seek for the differentially-expressed proteins in patients with kidney-yin deficiency syndrome and to screen out the specific proteins,so as to provide evidence for the establishment of objective standard of kidney deficiency syndrome of traditional Chinese medicine (TCM).Methods Five patients with typical kidney-yin deficiency syndrome and 6 normal healthy volunteers were enrolled into the study.Plasma proteins in both groups were detected by antibody chip,and then the plasma proteins profile was compared and analyzed.Results A total of 25 differentially-expressed proteins between kidney-yin deficiency group and normal control group were found,of which 2 were up-regulated and 23 were down-regulated.Conclusion The differentially-expressed proteins in patients with kidney-yin deficiency syndrome are mainly related to immune disorder,protein biosynthesis,metabolism,oxidative stress,cell apoptosis,signal transduction,and so on.

So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.
