The development of the course of end-of-life care education in medical colleges and universities at home and abroad: a scoping review / 中华医学教育探索杂志

The end-of-life care education of medical students is related to the development of hospice care in the future. This paper comprehensively reviewed the setting up situations of end-of-life care education courses at home and abroad, as well as the status quo of courses' implementation, including teaching contents, teaching methods, assessment methods, teaching staff, teaching evaluations and effects. Based on these aspects, we have made some thoughts and suggestions, in order to provide reference for the development of end-of-life care education courses in medical colleges and universities in China.

Investigation of attitudes toward death and hospice care in nursing students before internship / 中华医学教育探索杂志

Objective:To investigate nursing students' attitudes toward death and hospice care before they start clinical practice, analyze the correlation between the two attitudes and compare their differences in junior and regular nursing college students.Methods:A cross-sectional study was adopted to investigate the attitudes toward death and hospice care in 232 senior nursing students at school. Instruments included the Chinese version of the Death Attitude Profile-Revised (DAP-R) and the Chinese version of the Frommelt Attitude Toward Care of the Dying Scale-Form B (FATCOD-B). Pearson correlation analysis and independent t-test were used to analyze the data.Results:The mean scores of the 5 dimensions of death attitude were neutral acceptance (4.10±0.43), fear of death (2.76±0.66), death avoidance (2.73±0.74), approach acceptance (2.61±0.58), and escape acceptance (2.48±0.75), respectively. The total score of hospice care attitude was (107.63±8.45), which was negatively correlated with fear of death ( r=-0.247, P<0.01), death avoidance ( r=-0.278, P<0.01), and escape acceptance ( r=-0.145, P<0.05) scores and positively correlated with neutral acceptance score ( r=0.405, P<0.01). The death avoidance score of regular nursing college students was significantly lower than that of junior nursing college students ( t=-2.043, P<0.05), and the hospice care attitude score of regular nursing college students was significantly higher that of junior nursing college students ( t=2.639, P<0.01). Conclusion:There is a big room to improve nursing students' attitudes toward death and hospice care. Strengthening end-of-life care education is imperative.

Preliminary application research of Ultrafast Doppler for renal artery ultrasonography / 中华超声影像学杂志

Objective To analyze the accuracy,repeatability and feasibility of Ultrafast Doppler for renal artery ultrasonography.Methods One hundred and one cases were selected that were suspected to have renal artery disease and were successful of conventional and Ultrafast Doppler for renal artery ultrasonography,and 101 cases were grouped by age (≤40 years old,41-60 years old,≥61 years old),body mass index (BMI) (normal 18.5-23.9 kg/m2,overweight 24.0-27.9 kg/m2,obesity ≥28.0kg/m2) and whether there were the presence of renal artery stenosis (no significant renal artery stenosis and renal artery stenosis ＞60％).Each case was respectively examined by conventional and Ultrafast Doppler for renal artery ultrasonography in a random order.The consistency of Doppler parameters was tested.The duration of each Doppler study was compared and the feasibility of Ultrafast Doppler for renal artery ultrasonography was explored.The Doppler parameters included:renal artery peak systolic velocity (PSV),resistance index (RI),renal segmental artery acceleration time (T) and time consuming (△T).The concordence and △T of two Doppler method were compared.Results ① Ultrafast Doppler had good reproducibility,intraclass correlation coefficient (ICC) values were ＞ 0.6.② For renal artery ultrasonography,the successful number of cases examined by Ultrafast Doppler were more than those examined by conventional Doppler,but the difference was not statistically significant (P ＞0.05).③The Doppler parameters from all subjects and different groups showed a strong positive correlation between the two Doppler studies (P ＜0.05).④ UltraFast Doppler required a shorter time than conventional Doppler (P ＜0.05).⑤The △T of cases with different ages and with or without renal artery stenosis showed no statistically significant (P ＞0.05),however,their △T were increased with body mass index increasing (P＜0.05).Conclusions Ultrafast Doppler for renal artery ultrasonography has a high success rate,a good repeatability and consistency,and a shorter time consuming and simple operation than conventional Doppler.

Role of endometrial and subendometrial blood flows measured by three-dimensional power Doppler ultrasound in the prediction of endometrial receptivity during IVF-ET treatment / 中华超声影像学杂志

Objective To investigate the role of endometrial and subendometrial blood flows measured by transvaginal three-dimensional(3D) power Doppler ultrasound in the prediction of endometrial receptivity during in vitro fertilization-embryo transfer (IVF-ET) cycles. Methods One hundred and twenty patients undergoing IVF-ET cycles were enrolled in this study. Transvaginal 3D power Doppler ultrasound examination was performed on the day of human chorionic gonadotropin injection to determine endometrial thickness,endometrial volume, vascularization index(VI), flow index(FI) and vascularization flow index (VFI) of endometrial and subendometrial regions by experienced sonograpbers. The patients were divided into pregnant group and non-pregnant group according to pregnant outcome. The data between the two groups were compared and analysed. Results There were no significant differences( P ＞0.05) between the pregnant group and non-pregnant group in endometrial thickness, endometrial volume. Endometrial and subendometrial VI,FI, VFI were higher in the pregnant group than those in the non-pregnant group, and statistical comparison had significant difference( P ＜0.05). Conclusions Endometrial and subendometrial blood flows measured by transvaginal 3D power Doppler ultrasound can be as a reliable indicator to assess endometrial receptivity and to predict the pregnancy outcome.

Comparative study of perihepatic lymph node in the healthy individuals and patients with hepatitis C virus infection on ultrasonography / 中华超声影像学杂志

Objective To determine the relation between enlarged perihepatic lymph node (PLN) and viraemia,and to find out whether there is a difference in PLN size between the healthy individuals and patients with hepatitis C virus (HCV) infection. Methods Seventy-four patients with HCV infection and 283 healthy individuals were examined by two-dimensional ultrasound. The length and thickness of lymph node were measured. The lymph-node area index(LN area index) was calculated. The LN area index was evaluated by the ROC curve and compared with serum HCV core antigen (HCV-Ag) levels by correlation analysis. Results Detection rate, the length and thickness, LN area index of group with HCV infection were significantly different by compared with the normal control group ( P < 0. 001 ). The ROC curve showed that the LN area index as a diagnostic indicator had high sensitivity and specificity. The LN area index showed a significant correlation with HCV-Ag level (r = 0.436, P <0.05), but no significant differences were found between LN area index and HCV-Ag grade. Conclusions Perihepatic lymphadenopathy indicates viraemia,and LN area index of 100 mm2 is a reference index in estimating whether patients have HCV infection.
