OBJECTIVE:To study the vasodilatation effects of the alcohol extract from Uighur medicine Ziziphora clinopodioi-des(EEZ)on isolated rat thoracic aorta vessel rings. METHODS:Isolated rat thoracic aorta vessel rings were prepared. There was a group with intact vessel ring endothelium and a group with vessel ring endothelium removed in the test. After preshrinking the ves-sel rings with phenylephrine(PE),EEZ of 100,300,500,700,900 and 1 100 mg/L was added gradually,concentration-vasodila-tation curve was drawn and maximal vasodilatation rate (Emax) and median effective concentration (EC50) were calculated. For the group with vessel ring endothelium removed,after the vessel ring was pretreated with EEZ at EC50 in calcium-free solution or calci-um-free high-potassium solution,CaCl2 of 0.4,0.8,1.2,1.6,2.0 and 2.4 mmol/L was added gradually,and calcium concentra-tion-tension curve was drawn;following the pretreatment of the vessel ring with EEZ at EC50,1 μmol/L PE was added and shrink tension was recorded and vasoconstriction percentages was calculated. RESULTS:EEZ had vasodilatation effect on the vessel ring preshrunk with PE in a concentration and smooth muscle-dependent manner. The group with intact vessel ring endothelium and the group with vessel ring endothelium removed respectively had Emax of (58.18 ± 16.23)% and (73.54 ± 17.21)%,and EEZ EC50 of 773.27 mg/L. For calcium-free high-potassium solution,EEZ could cause the calcium ion-vasoconstriction curve to move to the right obviously;for calcium-free solution,EEZ could inhibit the vasoconstriction caused by PE. CONCLUSIONS:EEZ has vasodi-latation effects by a mechanism which may be related to inhibiting calcium influx and intracytoplasmic calcium release through the inhibition of voltage-dependent calcium channels(VDCCs),and thus interfering intracytoplasmic calcium ion balance.

Objective:To understand the current situation of physicians′ competency in China and statistically analyze its influencing factors, hence providing referential evidences for promoting their competency.Methods:The evaluation scale for Chinese physicians′ competency was developed by referring to sophisticated overseas evaluation frameworks. Based on the electronic platform of the medical alliance, stratified sampling was conducted at 39 hospitals in 13 provinces, from which 2 156 physicians were surveyed, and statistical analysis was made on the current situation and influential factor of their competency in 6 dimensions(medical knowledge, diagnosis and treatment, scientific research and teaching, interpersonal communication, spirit of professionalism, population health)Results:The score range in multiple dimensions of physicians′ competency was between 2.85 and 3.89(5 in total), among which spirit of professionalism dimension scores the highest, and teaching and research dimension scores the lowest. Logistic regression analysis shows that their competency level in 6 dimensions is correlated to a range of factors, including gender, degree, title, supervisor qualifications, standardized training program of specialist physicians, and affiliation or not to teaching hospitals( P<0.05). Conclusions:Their overall competency is expected to be elevated. To name a few, they are lack of teaching and research abilities, and need to conduct clinical-oriented scientific research; they are expected to enrich knowledge structure, and need to embrace a wider concept of health; they need to improve their non-technical service abilities, and should further emphasize their humanistic quality; physicians′ practice competency depends upon their extent of medical education, and ensuring the quality of standardized training becomes the key measure.

OBJECTIVE:To study the spectrum-effect relationship of the antipyretic effect of Radix Bupleuri injection. METH-ODS:HPLC method was used to establish the fingerprint of Radix Bupleuri injection. The antipyretic effect of 10 batches of Radix Bupleuri injection on fever rats induced by dried yeast were determined respectively. The fingerprint peaks were screened,along with the temperature value of different time points(0,10,15,30,40,55,70 min). The principal components were extracted by principal component method and the indirect relationship between the fingerprint and antipyretic effect was analyzed,depending on the principal component correlation coefficient matrix. RESULTS:There were 39 common peaks in fingerprint(similarity>0.85), No. 8,12,14,19,26,31,34,35 and 39 common peaks with large peak area were included in the study. Four principal compo-nents were extracted by principal component analysis(87% of total variant). First principal component showed that the active com-ponents of the 12th peak may be related to the antipyretic effect of 6 to 13 hours. The second principal component showed that the active components of the 26th peak may be related to the antipyretic effect of 0.5 to 5 hours. The third principal component showed that the similar effect of the active components could be caused by 34th,35th and 39th peaks. The fourth principal component sug-gested that there were some similarities between the 14th and the 31st peaks. CONCLUSIONS:Radix Bupleuri injection have obvi-ous improvement for fever rats. There is certain corresponding relation between HPLC fingerprint and antipyretic effect of Radix Bu-pleuri injection .

Objective To investigate the relaxant effects of ethanol extract fromRhodiola crenulata (Hook.f.et Thoms.) H.Ohba in isolated rat thoracic aorta and its possible mechanisms.MethodsThe thoracic aortas from male Sprague-Dawley rats were isolated and cut into 3- to 4-mm-wide transverse rings, and the tension in endothelium-intact or endothelium-denuded aortic rings was recorded. The relaxant effects of ethanol extract fromRhodiola crenulata in various concentrations (100, 300, 500, 700, 900, and 1 100 mg/L) in aortic rings precontracted with phenylephrine (1 μmol/L) were observed. The effects of pretreatment with soluble guanylyl cyclase inhibitor ODQ (10 μmol/L) on the relaxant effects of ethanol extract fromRhodiola crenulata were observed. The effects of ethanol extract fromRhodiola crenulataon calcium-induced contractions in calcium-free high-potassium medium and phenylephrine-induced contractions in calcium-free medium were also observed.ResultsEthanol extract fromRhodiola crenulatashowed a concentration-dependent relaxation in aortic rings precontracted with phenylephrine. The maximal relaxations of ethanol extract fromRhodiola crenulataln endothelium-intact or endothelium-denuded aortic rings were 57.4% ± 21.81% and 60.51% ± 0.34%, respectively, with a half-maximal effective concentration of 1 062.88 mg/L. The relaxant effects of ethanol extract fromRhodiola crenulatawere not statistically inhibited by pretreatment with ODQ (P>0.05). Contractions of aortic rings resulted from phenylephrine-induced Ca2+ release from intracellular stores in calcium-free medium or high potassium-induced influx of Ca2+ in calcium-free high-potassium medium were significantly inhibited by ethanol extract fromRhodiola crenulata(allP<0.05).ConclusionEthanol extract fromRhodiola crenulatahas a concentration-dependent vasorelaxation, its mechanisms may be involved in blocking extracellular Ca2+ influx and intracellular Ca2+ release.
