Objective:To explore the effect of workshop situational teaching in practice training of midwifery specialty.Methods:89 students in midwifery specialty were divided into observational group and control group. The control group was given traditional teaching, and the observational group was implemented with situational teaching based on workshop. The effect of teaching was investigated by skill assessment, Chinese version of self-rating scale of self-directed learning and practice teaching quality evaluation questionnaire. SPSS 23.0 was used for t test.Results:The scores of 6 practical skills and the total scores of students in the observational group were higher than those in the control group, and the difference was statistically significant ( P<0.01, P<0.05). Study initiative, learning behavior, learning strategies, learning evaluation, interpersonal skills and self-directed learning ability of students in the observational group were all higher than those in the control group, and the difference was statistically significant ( P<0.01, P<0.05).The evaluation of teaching quality of the observational group was "excellent" and was "good" in the control group. There was no statistically significant difference in the scores toward teaching attitude of the observational group compared with the control group ( P>0.05). The total scores of teaching content, teaching methods, teaching effects and practice teaching quality of the observational group were higher than those of the control group, and the difference was statistically significant ( P<0.01). Conclusions:The workshop situational teaching was helpful in promoting the transformation of students' theoratical knowledge to practice, stimulate students' independent learning ability and improve the quality of practice teaching.

OBJECTIVETo observe the long-term relationship between body mass index (BMI) and cardiovascular events in male elderly hypertensive patients.

METHODSA total of 839 male elderly (>65 years old) hypertensive patients were included in this prospective study. Baseline data were obtained on January 2004 and participants were followed up yearly till January 2014. Patients were divided into 3 groups according to their BMI: normal weight group (18.5 kg/m² ≤ BMI<24.0 kg/²), overweight group (24.0 kg/m² ≤ BMI<28.0 kg/m²), obese group (BMI ≥ 28.0 kg/m²). All-cause death and cardiovascular events were compared.

RESULTSThe average age of all 839 hypertension men was (75.4 ± 4.8) years at baseline. Baseline systolic blood pressure was (133.7 ± 14.6) mmHg (1 mmHg=0.133 kPa), diastolic blood pressure was (74.3 ± 9.3)mmHg. Baseline systolic and diastolic blood pressure was similar among the three groups. All 839 patients completed follow-up. There were 178 all-cause deaths, 54 cardiovascular deaths, 51 new/recurrent myocardial infarctions and 105 new/recurrent strokes during follow up. Incidence of all-cause mortality in overweight group (16.74%,72/430) was significantly lower than in normal weight group (27.01% (74/274), P<0.05). Kaplan-Meier curves showed the all-cause mortality and cardiovascular mortality were higher in normal weight group than in the other two groups. According to the Cox proportional hazards regression model, the risk of all-cause mortality (RR=0.867, 95% CI: 0.792-0.949) and cardiovascular death (RR=0.179, 95% CI : 0.05-0.645) in patients with a BMI ≥ 24.0 kg/m² were lower than in the group with BMI<24.0 kg/m².

CONCLUSIONObesity paradox phenomenon is observed in elderly male hypertensive patients in that higher BMI is associated with lower mortality risks in elderly male hypertensive patients during the 10 years follow-up.
