Establishment and practice of the blended teaching model in human embryology / 中华医学教育探索杂志

Based on the virtual simulation of "digital embryo" in the digital teaching platform for medical morphology, this study constructs the course resources of human embryology by integrating the contents of the course, recording micro-videos, formulating course guides, and analyzing clinical cases, then implements the blended teaching model of pre-class preview, in-class discussion, and after-class expansion, and establishes a course evaluation system combining formative assessment and end-of-course assessment. Comparison of assessment scores and satisfaction questionnaire between traditional off-line teaching and blended teaching showed a significant improvement in total score, and more than 5% of the students reported a significant reduction in the difficulty of the course, while the degree of satisfaction with the course was increased by 11%. This suggests that the establishment of the blended teaching model of human embryology meets the requirements for personalized and diversified learning among students, realizes the diversity of teaching methods and teaching evaluation, and improves the quality of teaching.

Analysis of Antipsychotic Drugs Prescriptions in Outpatient and Emergency Department of Our Hospital dur-ing 2013-2014 / 中国药房

OBJECTIVE:To provide reference for rational use of drugs in patients with mental disorders. METHODS:In retro-spective investigation,47 386 prescriptions of psychiatric department in our hospital during Sept. 2013 to Aug. 2014 were analyzed statistically. RESULTS:Totally 39 496 cases were enrolled in the 47 386 prescriptions. The median age of patients was 31.42,with male to female ratio of 1:1.07;they were diagnosed as schizophrenia and other mental disorder,accounting for 65.34%,and fol-lowed by mood disorders,accounting for 15.20% . They were mainly given single drug and two-drug use,accounting for 30.80%and 61.68%respectively. Clozapine,quetiapine,risperidone were top 3 prescription drugs in the list of frequency;olanzapine,que-tiapine,risperidone were top 3 drug in the list of consumption sum. Among top 20 psychiatric prescription drugs,there were 7 kinds of drugs for schizophrenia and other psychiatric disorders,3 kinds of drugs for mood disorders. CONCLUSIONS:The use of antipsychotic drugs in our hospital is rational basically.

Analysis on detection and drug resistance of Ureaplasma urealyticum in 3 249 cases of cervical samples in Southern Fujian / 国际检验医学杂志

Objective To investigate the infection status of Ureaplasma urealyticum (Uu) and its situation of drug resistance . Methods The separation ,identification and drug resistance test plate was used for Uu detection in 3 249 cases of cervical samples . Results The total infection rate of Uu was 47 .18% (1 533/3 249) .The patients with Uu infection mainly distributed in >20-40 years ,with the constituent ratio accounted to 90 .8% .The sensitive rates of Uu to josamycin and doxycycline were both higher than 95 .00% ,however ,the resistant rate of Uu to azithromycin and ofloxacin were both higher than 50 .00% .Conclusion The drug re‐sistant strains of Uu were common .The clinic should choose the sensitive antibiotics for the treatment according to the results of drug sensitivity test .

Study on a test of screening to predict stroke-using cerebral vascular hemodynamic indexes / 中华流行病学杂志

<p><b>OBJECTIVE</b>To evaluate efficacy and optimal cut-off-point through cerebral vascular hemodynamic indexes (CVHI) examination to predict stroke.</p><p><b>METHODS</b>A number of 20,333 people at 35 years old and over were checked by CVHI and accumulative score was calculated according to the value of detected indexes. Risk factors of stroke were investigated simultaneously. One hundred and sixty-eight patients with stroke occurred during 4-year following up. Typical syndromes and signs stroke were used as golden standard to evaluate screening efficacy of CVHI.</p><p><b>RESULTS</b>Score of optimal cut-off-point of cerebral vascular hemodynamic indexes was under 75 in ROC curve analyses. Sensitivity, specificity, accuracy, positive and negative predictive values, positive and negative likelihood ratios as well as Youden's index for predicting stroke within 4 years after examination were found to be 87.50%, 67.70%, 67.86%, 2.21%, 99.85%, 2.71, 0.18 and 0.55 respectively. Sensitivity and positive predict values for predicting cerebral vascular thrombosis were superior to predicting cerebral hemorrhage. Positive predicting value in risk exposure population was higher than that of overall population. Coefficiency of variation of cerebral vascular hemodynamic examination was 4.03%. The agreement rate of examination between two physicians was 97.62% and Kappa value was 0.94.</p><p><b>CONCLUSION</b>The score of optimal cut-off-point of cerebral vascular hemodynamic indexes examination was 75. Both Efficacy and reliability for predicting stroke seemed to be good, especially for predicting cerebral vascular thrombosis.</p>
