Objective To assess the possible sequestration of remifentanil by the extracorporeal circuit.Methods Two types of extracorporeal circuits (ECCs) were used-Xijian type I (group A)and AFFINITY(R) NT(group B),while in control group (group C) a glass container was used.The ECC and glass container were filled with priming solution (6%hydroxyethyl starch 1000 ml + lactated Ringer's solution 500 ml).Remifentanil Wag then added to the priming solution with the final concentration of 100 ng/ml.The priming solution was circulated in the closed ECC or stirred the glass container.The concentration of remifentanil in the priming solution was determined at 2,5,10 and 15 min after addition of remifentanil.Results The remifentanil concentration in the priming solution decreased by 75.1%,57.9% and 18.3%at 2 min after addition of the drug in group A,B and C respectively as compared with the baseline value.The remifentanil absorption by ECC was significantly greater in group A than in group B.There was no significant difference in remifentanil concentration at the 4 time points in each group.Conclusion ECC can absorb remifentanil.The remifentanil absorption by Xijian type I is significantly greater than that by AFFINITY(R).

Objective To analyze the effectiveness of doctor-patient communication course on improvement of doctor-patient communication ability.Methods Totally 360 eight-year program medical students of clinical medicine from Shanghai Jiaotong University School of Medicine were chosen as the research object and were divided into educational group(n=l80) and control group(n=180).Students in educational group study doctor-patient communication course while those in control group do not.SEGUE Framework was used to conduct exploratory research between educational group and control group.Accuracy of questionnaire database was examined by Excel software and logical test.KoImogorov-Smimov(K-S test) was applied to analyze the scores and (x ± s) was used to express the data through SPSS 16.0 statistical software.Comparison between group differences are statistically significant(P<0.05).Results Overall score was higher in educational group than in control group.Concerning of communication initiation,infomation collection and understanding of patients,scores of educational group were significantly higher than those of control group(P=0.001,P=0.002 and P=0.007,respec-tively).Furthermnore,KoInogorov-Smimov(K-S test) and (x ± s) statistical results showed that scores of detailed items were higher in educational group than in control group as well.Conclusions Doctor-patient communication course is of great importance to help medical students practice physician-patient communication based on related knowledge learning,but course content setting remains to be further improved.

Objective To investigate the mechanism by which remifentanil decreases blood pressure during cardiopulmonary bypass (CPB).Methode Twenty-six ASA Ⅱ or Ⅲ patients (NYHA's classification grade Ⅱ or Ⅲ ) of both sexes and aged 20-55 years were randomized to receive remifentanil (group R, n = 13) or normal saline (group C, n = 13). Remifentanil 10 μg/kg or equal volume of normal saline was administered via a venous reservoir when cardiac arrest was induced with cardioplegic solution. The flow rate resistance (SVR) were measured and arterial blood samples were taken for determination of plasma concentrations of histamine,nitric oxide (NO) and 6-keta-prostaglandin F1α(PGF1α) before T0 and at 5, 10, 15 min (T5.10.15) after remifentanil administration.Results Remifentanil administration was associated with a significant decrease in MAP and SVR at T5 and T10 as compared with the baseline values at T0 ( P < 0.05); whereas in control group, MAP and SVR were significantly increased at T5, T10 and T15 as compared with the baseline values at T0 . There were no significant differences in plasma histamine, NO and PGF1α concentrations between the two groups.Conclusion Remifentanil reduces SVR and causes a decrease in BP but without altering plasma concentrations of histamine, NO or PGl2.

0.05).However,50.0% of T1 patients with TNBCs had lymph node metastasis,which was much higher than the other 2 groups.The recurrence rate in TNBC,non-TNBC or Her-2 positive patients were 57.1%,40.5% and 44.2%,respectively.The triple negative group had higher tumor recurrence rate than the other two groups(P=0.03).The overall 3 year survival rate of the TNBC group was 58.9%,which was much lower than the other two groups(76.4% for the luminal a and b group and 74.8% for the Her-2 positive group(P=0.04).Conclusion:The TNBCs was higher in premenopausal patients well as a higher lymph nodes metastasis rate with small tumor size.Moreover,three years recurrence and mortality rates in this group is higher than the non-TNBC groups.
