Interventional radiology is mostly carried out under local anesthesia with micro invasive characteristics.However,the questions of patient's pain,nerve intense,change of blood pressure and heart rate always influence the performance of operation.General anaesthesia in interventional radiology is a comparatively simple venous anaesthesia modality with a controlled dose of anesthetics injecting via periphery vein through persistent minimally injecting pump to keep the patient in dormancy under electrocardiagraphic monitoring.It doesn't require a tube insertion of trachea.The anaesthesia depth and time are under control.The half-life of the anaesthesia drugs is short with less side-effect.It is necessary to introduce the advanced anaesthesia into commom interventional radiological therapy with attentions of promoting the development through new modalities.

Objective:To determine the related substances in dexibuprofen and its sustained release tablets by HPLC .Methods:The related substances including a-methyl-4-butyl benzene acetic acid , L-ibuprofen and the others were detected by HPLC .An Agilent Eclipse XDB-C18 column (150 mm ×4.6 mm, 5 μm) was used for a-methyl-4-butyl benzene acetic acid and the other related sub-stances.A Kromasil 5-TBB column (250 mm ×4.6 mm, 5 μm) was used for L-ibuprofen.The mobile phases was acetonitrile and phosphate solution (45 ∶55, pH value was adjusted to 2.5 by phosphoric acid), hexane-tert-butyl ether-acetic acid (850 ∶150 ∶1), acetonitrile and sodium acetate buffer (60 ∶40, 6.13g sodium acetate was dissolved in 750ml water, and pH was adjusted to 2.5 by glacial acetic acid ) , respectively .The detection wavelength was 214 nm, 220 nm and 263 nm, respectively .The flow rate for a-meth-yl-4-butyl benzene acetic acid and the other related substances was 1.0 ml· min-1 .The flow rate for L-ibuprofen was 2.0 ml· min-1 . The column temperature was 30℃and the injection volume was 20 μl.Results:The method could effectively detect the contents of a-methyl-4-butyl-phenylacetic acid and L-ibuprofen, and identify and separate the related substances in dexibuprofen raw material and its sustained release tablets .Conclusion:The method is specific , accurate and easy to operate , which can be used for the quality control of ibuprofen raw material and its sustained release tablets .

Objective To investigate the effects of hypertonic saline in the treatment of children with critical hand, foot and mouth disease (HFMD).Methods The 250 pediatric patients with HFMD hospitalized from January 2011 to Januar-y 2013 in our hospital were randomized into the control group treated routinely and the experimental group treated with hyper-tonic saline on the basis of general conventional treatment .The therapeutic effect and sodium ion concentration in the children of two groups were observed and compared.Results The treatment effect of the experimental group was obviously better than that of the control group (p<0.05).Sodium ion concentration and incidence of adverse reactions in two groups before treat-ment showed no significant differences (p>0.05), while the sodium ion concentration of the experimental group was much higher than that of the control group on the 4th and 6th treatment day (p<0.05).Conclusion Hypertonic saline treatment can significantly enhance the therapeutic effect, increase the sodium ion concentration and improve the prognosis in children with critical HFMD.Therefore, hypertonic saline treatment for patients with clinical HFMD has a very important clinical sig-nificance and it is worth popularization and application.

Recent studies suggest that astrocyte elevated gene 1 ( AEG-1 ) is almost highly expressed in all types of malignant solid tumors and correlates with poor prognosis,which becomes a prognostic marker for many kinds of tumors.As a strongly basic protein,AEG-1 possesses a transmembrane domain and multiplenuclear localization signals.It is present in the cell membrane,cytoplasm and nucleus.As an oncogene,AEG-1 palys an important role in a virety of malignant biological behaviors of cancer,which range from cell proliferation,apoptosis,migration,adhesion,invasion to tumor angiogenesis and chemotherapy resistance.Its critical role in tumor genesis and progression has made it a potential therapeutic target.

AIM　to compare the bioavailability and pharmacokinetics of two acyclovir tablets. METHODS　Concentrations of acyclovir in 10 men serum after po 600 mg of two acyclovir tablets were determined , in random 2-way crossover design. Pharmacokinetic parameters were also estimated. RESULTS　The peak concentrations of test and reference tablets were 1.24±0.49 and 1.17±0.20 μg/ml, the AUC 7.56±1.80 and 7.56±2.10μg*h/ml, respectively. The relative bioavailability was 101.36%±11.62%. The test formulation was found bioequivalent to the reference in AUC and Cmax by two one-side t test. CONCLUSION　Two tablets were bioequivalent.

Objective To explore the attentional bias in first-episode depressive patients and the correlations between the attentional bias.Methods In the beginning of the treatment,a total of 34 first-episode depressive patients in treatment-naive and demography matched 40 healthy controls completed the Chinese Emotional Stroop Task that assessed the attentional bias.Results The comparison between depressive patients and healthy controls on the reaction time of negative,neutral and positive-related words were significant ((1185.71±410.60)ms/(754.68±215.36) ms,t=5.775,P＜0.01 ; (1127.92±344.89) ms/(755.37±213.49) ms,t=5.675,P＜0.01 ;(1166.17±395.72) ms/(761.70± 194.66) ms,t=5.708,P＜0.01 respectively).Through analysis of variance,the difference of error numbers among the neutral,negative and positive-related words ((3.41 ± 2.11) times,(2.24±1.65) times,(2.97± 1.17) times) in the depressive patients were significant (F=4.197,P=0.018).The difference of error numbers between negative-related words and neutral-related words were significant through analysis of least significant difference(P＜0.01).Conclusion The results suggest that depressive patients before treatment have attentional bias in negative-related word.Attentional bias in negative-related stimuli may be one of the characteristics of cognitive function in first-episode depressive patients.

Objective:To evaluate the application of flipped classroom based on rain classroom in standardized residency training of orthopedics.Methods:Sixty-two orthopedics residents were randomly divided into flipped classroom teaching group and traditional teaching group, with 31 residents in each group. The flipped classroom teaching group the flipped classroom teaching mode based on rain classroom, including three aspects: learning in advance before rain classroom, personalized discussing cases in class and teaching after class. The theoretical knowledge, clinical skills and evaluation of teaching activities were compared between the two groups. SPSS 19.0 was used for rank sum test and chi-square test.Results:All the residents completed the evaluation of theoretical knowledge, clinical skills and effect. The results showed that the scores of theoretical knowledge and clinical skills in the flipped classroom teaching group were (88.7±10.3) points and (26.8±2.2) points, which were significantly higher than those of the traditional teaching group (79.2±18.6) points and (20.4±2.9) points, with statistical significance ( P<0.05). The evaluation of teaching activities, including participation, satisfaction, enthusiasm and learning effect, was significantly better than that of the traditional teaching group ( P<0.05). Conclusion:In the orthopedics standardized residency training and teaching activities, the application of flipped classroom teaching mode based on rain classroom is conducive to improving students' learning performance, cultivate their autonomous learning ability, and improve their learning satisfaction and enthusiasm.

Most of the current medical humanities education focuses on the moral aspects without good theoreti-cal basis and specific practices on the medical institution and daily life.The article dates back to the origins of So-cial Science based on the concept caregiving put forward by the medical anthropologist Arthur Kleinman,and states that the ultimate purpose of Social Science is to make response to the social suffering and provide caregiving for it.Caregiving as moral experience is response to social suffering and attracts much importance,because it pro-vides both the theoretical basis and practical means for the current medical humanities education.Its characteristics of caregiving as moral experience to social suffering and caregiving as reciprocity meet the demands of current notion of Big health in China.
