ABSTRACT
Objective:To explore the effect of introducing mixed reality technology into traditional atlas teaching to teach airway anatomy under bronchoscopy.Methods:A total of 30 Batch 2017 fifth-year clinical medicine students from Shanghai Jiao Tong University School of Medicine were randomly divided into control group and test group by RAND function in Excel, with 15 students in each group. The control group was taught with the traditional bronchoscopic atlas teaching, and the test group was combined with mixed reality technology. The two groups had the same class time. After teaching, the teaching effect was evaluated by examination and evaluation questionnaire. SPSS 25.0 software was conducted for t test and Mann-Whitney U test. Results:The average score after teaching of test group was (61.67±20.15), and that of control group was (36.67±13.32), with statistically significant differences ( t=4.01, P<0.001). According to the questionnaire results, the scores of the test group on course understanding, course concentration, participation, mastery and satisfaction were better than those of the control group, and the differences were statistically significant ( P<0.05). Conclusion:Using mixed reality technology to assist the clinical teaching of airway anatomy under bronchoscopy can improve the quality of students' study and enhance their understanding of the teaching content and students' participation passion, achieving better teaching effect.
ABSTRACT
Objective To investigate the association between maternal body height and risk of preterm birth.Methods A total of 11 311 pregnant women who gave birth of live singletons were recruited from the Healthy Baby Cohort Study in Hubei province,China from September 2012 to October 2014.Finally 11 070 pregnant women were selected as study subjects.Data were collected by using questionnaires,their prenatal care records and medical records.The women were divided into 4 groups according to the quartiles distribution (＜158 cm,158-cm,160-cm,and ＞164 cm).Gestational age was estimated according to maternal last menstrual time.Preterm birth was defined as delivering a live singleton infant at 28-37 weeks' gestational age.Logistic regression was used to calculate the odds ratios (OR) and 95％ confidence intervals (CI) for the association between body height and preterm birth.Results Among the 11 070 pregnant women,the incidence of preterm birth was 5.9％.Logistic regression analysis indicated that women in group with body height ＜ 158 cm had 46％ (OR=-1.46,95％CI:1.16-1.83) higher risk of giving preterm birth than those in group with body height ＞ 164 cm after adjustment for potential confounders.Every 1-cm increase in body height was associated with 3％ lower risk of preterm birth (OR=0.97,95％CI:0.95-0.99).Conclusion Shorter body height was a risk factor for preterm birth.It is necessary to strengthen the monitoring in pregnant women with short body height to reduce the risk of preterm birth.
ABSTRACT
Objective@#To explore the relationship between weight change and the changes in blood pressure, blood glucose and blood lipid profiles in middle-aged and elderly Chinese people.@*Methods@#All participants were from the Dongfeng-Tongji cohort study. The study included 16 606 middle-aged and elderly Chinese people with complete information in the baseline survey in 2008 and the first follow-up survey in 2013. We collected the data on demographic characteristics, lifestyle, history of diseases and medication, and the results of medical health examinations, including height, weight, blood pressure, fasting blood glucose and lipid profiles. We divided the weight change into five groups, moderate or above weight loss (<-8.0%), slight weight loss (-8.0%, -3.1%), weight maintenance (-3.0%, 3.0%), slight weight increased (3.1%, 8.0%), and moderate or above weight increased (>8.0%). Generalized linear regression model was used to analyze the relationship between weight change and the changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Subgroup analyses were used to explore the influences of gender, age and baseline BMI level on the relationship between weight change and the above-mentioned metabolic indicators.@*Results@#The average age of participants in baseline survey was (62.19±7.28) years with a range of 45 to 89 years. During the five-year period, there were 18.86% (2 633), 28.03% (4 655), 35.87% (5 956), 13.96% (2 319), 6.28% (1 043) people with moderate or above weight loss, slight weight loss, weight maintenance, slight weight increased, and moderate or above weight increased, respectively. Regression analyses showed that body weight change were positively correlated with changes in SBP, DBP, FBG, TC, LDL-C and TG, and negatively correlated with change in HDL-C (all linear trend P values were<0.05); As every 10% of weight changed, the β (95%CI) of changes in SBP (mmHg) (1 mmHg=0.133 kPa), DBP (mmHg), FBG (mmol/L), TC (mmol/L), LDL-C (mmol/L), HDL-C (mmol/L) and TG (mmol/L) were 4.94 (4.32, 5.55), 2.50 (2.11, 2.88), 0.05 (0.02, 0.08), 0.13 (0.11, 0.16), 0.14 (0.12, 0.16), -0.05 (-0.07, -0.04) and 0.16 (0.14, 0.18), respectively. Furthermore, subgroup analyses showed that weight change can lead to greater changes in blood pressure in older and overweight or obesity elderly people (all P for interaction<0.05).@*Conclusion@#Weight loss was beneficial for middle-aged and elderly people to improve the blood pressure, blood glucose and blood lipid profiles, regardless of the weight at the baseline, while weight gain was not.

ABSTRACT
Objective To confirm the correlation between pre or post processing semen parameters and clinical pregnancy rate in infertile couples with male factors undergoing intrauterine insemination (IUI) .Methods The pregnancy rate based on ovulation in‐ducing agent in infertile couples with male factors infertility per the 2010 world health organization criteria treated with IUI was e‐valuated .One hundred and twenty eight cycles were divided into pregnant group (16 cycles) and non‐pregnant group(112 cycles) . The pre or post processing semen parameters were retrospectively evaluated .Results The overall pregnancy rate was 12 .5% .All parameters in this study has no statistically significant difference between the two groups (P>0 .05) .Logistic multivariate analysis showed that there was no significant correlation between semen parameters and clinical pregnancy rate (P> 0 .05) .Conclusion There are no significant correlations between semen parameters and clinical pregnancy rate when the normal forms of patients with male infertility was 4% or higher .No semen parameters could predict results of clinical pregnancy .
ABSTRACT
Objective To analyze factors influencing β-blocker response rates of patients with portal hypertension and to explore the effect of nursing interference for increasing response rates with goal-directed nursing model. Methods 83 cases of portal hypertension were enrolled.Questionnaire about medical visiting behaviors and medication compliance were compared and analyzed after routine medication for 3 months.Bivariate and multivariate regression analysis were performed and related factors were used to establish a goal-directed nursing model for nursing interference guidance.52 non-response patients were randomly divided into the study group(27 cases)and the control group(25 cases).In the study group,compensation system and supportive-education according to Orem model were given,while the control group was given routine nursirng.Response rates and related factors were compared after 3 months of nursing intervention. Results Awareness of self-care responsibility,knowledge about the medication target,risk of sudden drug withdrawal,related medical knowledge,ability for pulse rate measurement and dose adjustment according to pulse rate changes were related to the response rates.Multivariate regression analysis showed that awareness of self-care responsibility,sudden drug withdrawal,utilization of social support and regular return visit were the independent factors.In the study group,ability for pulse rate measurement and dose adjustment acconding to pulse rate changes improved,phenomenon of sudden drug withdrawal declined and response rate increased,comparing with the control grpup. Conclusins For patients fail to respond to β-blockers,compliance behavior and medication compliance should be analyzed,and much attention should be paid to the education of the related medical knowledge,risk of sudden drug withdrawal and drag using targets.Goal-directed medel could be a guidance for nursing intervention to increase the response rates.
