Objective To explore the relationship of psychological flexibility and the anxiety ,depression in ischemic cerebrovas‐cular disease (ICVD) patients .Methods Two hundred cases of ischemic cerebrovascular disease were collected ,and their anxiety and depression level and psychological flexibility were measured by self‐evaluation of anxiety scale (SAS) ,self‐evaluation of depres‐sion scale (SDS) ,acceptance and action questionnaire‐Ⅱ (AAQ‐Ⅱ ) and cognitive fusion questionnaire (CFQ ) .According to the test results ,the patients with anxiety and depression were divided into different degree :degrees :normal ,mild ,moderate or severe . Results The AAQ‐Ⅱ and CFQ of the patients with anxiety depression were significantly higher than normal emotional ICVD pa‐tients (P<0 .01);there were statistical significance in the difference of the level of AAQ‐Ⅱ and CFQ and the degree of anxiety and depression in these patients (P<0 .01);the level of AAQ‐Ⅱ and the degree of anxiety depression was positively correlated (r=0 .778 ,P<0 .01 ;r=0 .759 ,P<0 .01);the level of CFQ and the degree of anxiety depression was positively correlated (r=0 .785 , P<0 .01 ;r=0 .774 ,P<0 .01);with SAS ,SDS ,as dependent variable ,the AAQ‐Ⅱ ,CFQ as independent variables ,through multiple linear regression analysis ,suggested that psychological flexibility was the impact factor of anxiety depression .Conclusion For pa‐tients with ICVD ,psychological flexibility is closely related to the degree of anxiety depression .Psychological flexibility is one of the predictor of anxiety depression .

Objective To assess the efficacy of cardiac resynchronization therapy (CRT) using real-time three-dimen?sional echocardiography (RT-3DE) and speckle tracking imaging (STI) in patients with heart failure. Methods Thirty-one patients with chronic heart failure were examined by RT-3DE and STI before CRT and 3, 6 months after CRT. The values of left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were measured. RT-3DE was used to evaluate the minimum regional volume for 16 segments (Tmsv-16SD) and the ratio of Tmsv16SD to R-R interval, and the maximum time difference (Tmsv-16Dif). STl was used to evaluate the ratios of standard deviation of the time to peak longitudinal radial and circumferential strain to R-R interval (Tls-16SD%, Trs-16SD%,Tcs-16SD%) from the beginning of Q wave of electrocardiography to the point minimal systolic volume of all 16 segments and the maximum time difference. Results The values of LVEDV and LVESV were smaller 3 and 6 months after CRT than those before CRT. The value of LVEF was significantly improved after CRT (P < 0.05). The values of Tmsv-16SD%, Tmsv-16Dif%, Tls-16SD%, Trs-16SD%, Tcs-16SD%and T-Dif%were gradually decreased after CRT (P<0.05). The values of Tmsv-16SD%, Tmsv-16Dif%,Trs-16SD%and Tcs-16SD%were negatively related with LVEF (r=-0.79,-0.82,-0.69 and-0.74(P<0.05). The better consistency was found between RT-3DE and STI methods(Kappa=0.77). Conclusion Re?al-time three-dimensional echocardiography and speckle tracking imaging can provide more accurate quantitative informa?tion of cardiac resynchronization therapy for assessment of treatment and prognosis in patients with heart failure.

Structural heart disease includes congenital cardiovascular structural abnormalities, valvular heart disease and cardiomyopathy, which shows the common features of cardiac anatomical structure and hemodynamic abnormalities, especially anatomical abnormalities. Echocardiography, especially three-dimensional (3D) ultrasound, is good at displaying anatomical structure and blood flow abnormalities. As a non-invasive method of examination, it has advantage in the evaluation of such heart diseases. In recent years, the gradual rise of 3D printing technology can make physical printing, and the printed heart model can stereoscopically display abnormal state of heart diseases. Ultrasound combined with 3D printing technology may provide more intuitive and accurate information for the assessment of structural heart disease.

Objective To investigate effects of problem-based learning (PBL) and traditional learning (TL) on students' long-term memory and clinical practice ability. Methods Totally 79 5-year-program undergraduates of 2006, 2007, 2008 grade in school of clinical medicine of our hospital were randomly divided into PBL group (n=38) and TL group (n=41). The teaching effects were evaluated by two exams as well as teachers' subjective impression. SPSS 17.0 statistical analysis software was used;exam results were expressed as x±s; t test and rank sum test were used to analyze the exam results and subjective impression. α=0.05 was set as inspection level. Results In the second exam after 6 months, the mean exam scores were (76.66 ±5.94) and (73.59 ±5.74) in PBL group and TL group, without significant differences between the two groups (t=1.85, P=0.068). However, at clinical intern-ship stage, PBL group outperformed TL group based on the subjective evaluation (P=0.065, 0.277). Conclusion PBL can culture students' ability of problem-solving, but it is limited in culturing long-term memory.

OBJECTIVE:To provide theoretic support for medicine affordability evaluation in China by studying medicine af-fordability evaluation methods. METHODS:Through introducing the concept and evaluation methods of affordability,the evalua-tion steps of“catastrophic expenditure”and“medicine affordability”in medicine affordability evaluation methods were interpreted systematically. RESULTS & CONCLUSIONS:The catastrophic expenditure and impoverishing effect methods can measure med-icine affordability,but they both have limitations. Catastrophic expenditure evaluation method cannot measure the consequences of a catastrophic expenditure to the family,and ignore the reduction of family income after the occurrence of diseases. Impoverishing effect evaluation method cannot pay attention to originally poor population. These two evaluation methods complement each other, and can more objectively reflect the ability of patients bearing medical expenses,which can provide scientific references for poli-cies of enhancing medicine pricing and reimbursement system.

Objective To investigate the diagnostic value of preoperative real-time three-dimensional color Doppler transthoracic echocardiography on assessment of patients with structural heart disease (SHD). Methods A total of 111 pa?tients were assessed preoperatively using real-time three-dimensional color Doppler transthoracic echocardiography (RT-3D-CDTTE), which include 31 SHD patients and 80 patients without SHD that were designed as negative control. Conven?tional two-dimensional color Doppler transthoracic echocardiography (2D-CDTTE) were used to compared with RT-3D-CDTTE while cardiovascular angiography and intraoperative findings were used as“Golden Standard”simultaneously. First of all, preoperative echocardiographic examination were performed and diagnosis was given. Angiography and intraoperative findings were hired to verify the accuracy of echocardiographic diagnosis before operation. Results (1) The preoperative RT-3D-CDTTE displayed three-dimensional structure and hemodynamic status of SHD cardiac lesions clearly, which were consistent with cardiovascular angiography and intraoperative findings. (2) P value of McNemar test between 2D-CDTTE and“Golden Standard”was greater than 0.05, Kappa=0.654 (P<0.001). P value of McNemar test between RT-3D-CDTTE and“Golden Standard”was greater than 0.05, Kappa=0.932 (P<0.001). Conclusion RT-3D-CDTTE can provides essen?tial information for preoperative evaluation which is important for decision of SHD management.

Objective To detect 10 kinds of human milk oligosaccharides (HMOS) and compare their amounts during lactational stage.Methods Breast milk samples in different stages of lactation as colostrum (day 0-7 postpartum),transitional milk (day 8-15 postpartum),and mature milk (day 16-180 postpartum) were collected and 10 HMOS in those samples were detected and quantified by ultra high performance liquid chromatography-fluorescence detection after fluorescence labeling by using standard curves.Correlations between HMOS and lactation day were conducted by Person correlation analysis method,while the differences among three stages were calculated by ANOVA test.Results Ten HMOS were successfully separated and quantified under chosen chromatographic parameters.2'FL,3'SL,6'SL,LNT,LNnT and LNFP-I were negatively correlated and 3'FL was positively correlated with lactation days.They were different in three lactational stages (P < 0.05),while P1,LNFP-V and LNnFP-V showed no correlation and difference (P > 0.05).Conclusion The amount of HMOS changed during lactational stages.Seven HMOS were correlated with lactation days and different in three lactational stages (P < 0.05).
