Application of modified DOPS as formative assessment in clinical skills training for professional graduate students / 中华医学教育探索杂志

Objective:To explore the application effect of modified direct observation of procedural skills (DOPS) as a formative assessment tool in clinical skills training of professional graduate students.Methods:A total of 130 professional graduate students of Batch 2019 were selected as the experimental group, and 127 graduate students of Batch 2018 were selected as the control group. Two groups of students received clinical general skills training after enrollment, the control group adopted the traditional skills teaching method, and the experimental group added DOPS as formative assessment on the basis of traditional teaching. The teaching effect of DOPS was evaluated by means of scores analysis and student self-assessment. SPSS 23.0 was used for t-test. Results:The score of the experimental group (84.35±3.41) was higher than that of the control group (77.58±2.68), which showed a statistically significant difference ( t=2.63, P<0.05). The scores of "skill operation ability" and "communication ability" were the lowest single indexes in the assessment of DOPS. The results of self-assessment showed that the scores of autonomous learning ability, clinical thinking ability, clinical practice ability and professional accomplishment of students in the experimental group were all higher than those in the control group ( P<0.05). Conclusion:Modified DOPS is helpful to improve clinical core ability, which is worth promoting for application.

Reform on training mode of clinical medicine postgraduates with professional degree / 中华医学教育探索杂志

The enrollment scale of clinical medicine postgraduates with professional degree was expanded each year in order to meet the needs of the society.How to train high quality medical talents in line with modem medical education and people's health needs was the problem we were confronted with.The affiliated hospital of Inner Mongolia medical university lunched reform on training mode of clinical medicine postgraduates with professional degree; the concrete measures included increasing postgraduate pre-service training,implementing tutor responsible system,applying PBL teaching and focusing on the overall quality training.Students' clinical competence was improved after the reform.

Expression and relationship of basic fibroblast growth factor and platelet-derived growth factor in femoral neck fracture / 中国综合临床

Objective To investigate the expression and distribution of basic fibroblast growth factor (bFGF)and platelet-derived growth factor (PDGF)in the different phases of femoral neck fracture.Methods Immunohistochemical assays were used to determine the expression and distribution of bFGF and PDGF protein in 36 human specimen of femoral neck fracture.A was measured and analyzed by CMIAS color imaging analysis system for signals of bFGF protein were found high in the mesenchymal cells,monocyte and vascular endothelial cells at 1st week after fracture in 9 subjects,with A of (0.4076 ±0.0902).The weakly positive signals of PDGF protein were found in the mesenchymal cells,while strongly positive in the vascular endothelial cells with A of (0.2261 ±0.0636).At 2rd week,in 9 cases the expression of bFGF and PDGF was strongly expressed in fibroblasts,endothelial cells,cartilage cell and cartilage matrix,osteoblast,with A of[(0.6404±0.0920)and (0.7457±0.0756)]and significandy higher than that at 1st week (P＜0.05,P＜0.01).There was no significant difference between the 3rd and 3nd week with A of[(0.7168±0.1346)and (0.8033±0.0491),P＞0.05 ].The expression of bFGF and PDGF protein was reduced obviously at 4th week but was positive in young and cartilage tissue,with A of [(0.5374correlation between bFGF and PDGF protein in different phases (r1week=0.792,r2week=0.834,r3week=0.880,entiation of cartilage cell and osteoblast,and induce proliferation of vascular endothelial cells and new blood vessel.③ Both bFGF and PDGF are bone growth factors, cooperating in regulating proliferation and differentiation of cartilage cell and osteoblast for fracture healing.

Three hundred patients with cerebrovascular disease within onset of 3 days were evaluated C-reaction protein level and cerebrovascular disease prognosis / 中华全科医师杂志

Three hundred cerebrovascular disease (CVD) patients (disease onset <3 days) were evaluated for serum C-reactive protein (CRP) level at admission, and Scandinavian Stroke Scale (SSS) or Oxford Handicap Scale (OHS) at baseline and 3 months. Based on serum CRP levels, the participants were divided into group A [CRP(1.20 ±0.35)mg/L], group B[CRP(4.98 ± 1.08) mg/L] or group C[CRP (19.34±12.27)mg/L]. Our results showed that serum CRP level was positively correlated with SSS (r = 0.39 or0.43, both P<0.01) and OHS (r=0.40 or0.42, both P<0.01) at3 months. Thus, evaluating serum CRP level within 3 clays of disease onset might be helpful in predicting clinical outcomes of CVD patients.

Real-time quantitative RT-PCR for measurement of expression of eNOSmRNA and Tie-2mRNA in BMSCs-derived Endothelial Cells / 中国矫形外科杂志

0.05).[Conclusion]BMSCs could be successfully differentiated into endothelial cells in vitro,and the functional genes were stably expressed in BMSCs-derived endothelial cells.They are ideal donor cells of tissue engineering vascularization.
