ABSTRACT

Objective:To investigate the effect of curriculum on the awareness and attitude on the rural-oriented medical education among medical students.Methods:The grade 2019 and 2020 medical students of rural-oriented program in Hebei Medical University were enrolled. Two different curricula were adopted in the first year, for students of grade 2020 more courses in general medicine, humanities and social sciences were added, and not for those of grade 2019. A questionnaire survey was conducted at the end of their first academic year. The questionnaire contained the basic information of students, opinions and satisfaction with curriculum design, understanding of policies about rural-oriented medical education, and the sense of career identity; each item in the questionnaire was scored by 5-point Likert scale.Results:A total of 173 questionnaires were distributed and 161 valid questionnaires were recovered, with a recovery rate of 93.1%; there were 55 responders (15 males and 40 females) from grade 2019, and 106 from grade 2020 (52 males and 54 females). The main reasons for choosing rural-oriented program were job security (60.0% (33/55) in 2019 and 58.5% (62/106) in 2020), the main way to know the relevant policies of the program was through the internet (54.5% (30/55) in 2019 and 66.0% (70/106) in 2020); 34.5% (19/55) of grade 2019 students were willing to continue working in rural areas after contracted period of service, while the percentage was 47.2% (50/106) for grade 2020. Students in grade 2020 had a higher satisfaction scores on the content and quality of teaching courses, as well as teaching satisfaction compared to those in grade 2019( t=2.34 and 3.00, P<0.05). The awareness of relevant policies before enrollment and policies related to contract violations among grade 2020 students was higher than that of grade 2019( t=2.70 and 5.08, P<0.05); the scores of all questions about general practice answered by students in grade 2020 were higher than those in grade 2019( t=3.96, 3.37, 3.55, 2.85, 3.84, 5.26 and 5.10,all P<0.05). There were no statistically significant differences in the scores of cognitive, emotional, behavioral, and adaptive aspects of career identity between students of two grades( t=0.70, 0.78, 0.74 and 1.37,all P>0.05). Conclusions:The reformed curriculum has positive effect on the satisfaction and awareness of rural-oriented medical education program and relevant policies among medical students in the program; however, it has less effect on the sense of career identity and willingness to continue to work in rural areas after the contracted period of serve.

ABSTRACT

Objective:To survey the awareness status of risk factors for gastric cancer and related factors among residents in Shijiazhuang city.Methods:From October to November 2020, residents aged>18 years were selected through convenience sampling from Xinhua District and Yuhua District in Shijiazhuang for a face-to-face questionnaire survey. The demographic characteristics and awareness levels of risk factors for gastric cancer among 1 490 subjects were analyzed. The multivariate linear regression model was applied to analyze the related factors.Results:There were 522 male participants (35.0%) and 968 female participants (65.0%). The mean knowledge score of risk factors of gastric carcinoma in the respondents was 5.0 (1.0, 11.0). There were 57.0% (849/1 490) of the participants who had a low knowledge level about risk factors of gastric cancer. The more highly recognized risk factors were irregular diet (47.4%, 706/1 490), consumption of pickled foods (45.2%, 674/1 490), consumption of smoked foods (45.0%, 671/1 490); the less-recognized risk factors included physical inactivity (14.8%, 221/1 490), male sex (17.3%, 258/1 490) and older age (19.5%, 291/1 490). Only 26.8% (400/1490) of the participants regarded H. pylori infection as a risk factor of gastric cancer. Univariate analysis showed that educational level ( Z=39.34), marital status ( Z=53.31), monthly income ( Z=11.82), family member or friend ever having stomach problem ( H=-2.98), and family history of gastric cancer ( H=-2.34) were significantly associated with the knowledge score of risk factors for gastric cancer ( P<0.05). Multivariate analysis showed that compared to participants with educational levels of primary school or below, those with educational level of junior high school ( β=0.27, P<0.001), high school ( β=0.23, P<0.001), or college ( β=0.16, P<0.001) had a higher levels of knowledge of risk factors for gastric cancer; compared to unmarried participants, awareness of risk factors was significantly better in those who were married ( β=0.16, P<0.001), divorced ( β=0.05, P=0.039), or widowed ( β=0.06, P=0.027); compared to participants with monthly income<3 000 yuan, the subjects with monthly income from 5 000 to 10 000 yuan ( β=0.07, P=0.020) had a higher knowledge score; compared to participants with no family history of gastric cancer, subjects with family history had higher knowledge level of risk factors for gastric cancer ( β=0.06, P=0.029). Conclusion:The knowledge levels of risk factors for gastric cancer are generally low among residents in Shijiazhuang city. Educational initiatives are required to improve the awareness of risk factors for gastric cancer, and interventions need to be implemented concurrently to change unhealthy behaviors among residents in Shijiazhuang city.

A total of 165 questionnaires were distributed and 149 were valid with an effective rate of 90.3%. The contents of the questionnaire included the basic information of the trainees, the evaluation of the current training, and the needs of the GPs′ job-transfer training.Results:Among 149 participants, there were 131 (87.9%)from the secondary hospitals or above, 146(98.0%)with bachelor′s degree or above, and 128 (85.9%)with intermediate or above professional titles. The survey showed that 72.0%(67/93)thought the main reasons affecting participation in the training were busy work load and insufficient personnel, the main problems of training were too short training duration(45.2%, 42/93), the not focused training contents(38.7%, 36/93) and lack of practice(37.6%, 35/93). In the 149 trainees, 136(91.3%) thought that the most important contents should be standardized diagnosis and treatment of common diseases; 104(69.8%), 118(79.2%), 115(77.2%) and 98(65.8%) considered that the knowledge of prevention and health-protection, first aid, latest progress and chronic disease management were needed for training; 110(73.8%)and 80(53.7%)thought the mastery of clinical practice and basic theory were needed. And 57.7% (86/149)of the trainees believed that research training was needed, and there was significant difference in the demand for research training among participants from different work units and with different professional titles (χ 2=15.371,10.625,all P<0.05). The accepted training methods were case study(53.7%, 81/149) and practical work(37.6%, 56/149). For training duration, 43.6% (65/149) thought it should not exceed 6 months and 56.4% (84/149) preferred more than 1 year; there was a significant difference in demanded training duration among trainees from different work units, with different education background and professional titles (χ 2=16.225,6.243,25.966, all P<0.05). Conclusion:We need a multi-channel and multi-level training model to establish a better job-transfer training system for general practitioners, in order to meet different training needs and to improve the effectiveness of the training.

ABSTRACT

Objective To investigate the influence of WeChat + family centered health intervention on the self-efficacy of elderly hypertensive patients in General clinic. Methods A total of 102 elderly hypertensive patients aged≥60 years in General clinic from February 2017 to July 2017 were enrolled.They were divided into experimental group and control group with the table of random number, with 51 cases in each group. The experimental group used the WeChat+ family centered health intervention model,while the control group adopted the traditional health education model.The changes of blood pressure and self-efficacy were evaluated before intervention, 3 months and 6 months after intervention respectively. Results There were no statistic significant difference in blood pressure and self-efficacy total score between the two groups before intervention(P>0.05). At 3 months after intervention,the blood pressure(systolic pressure/diastolic pressure)of the patients were(144.20±4.60), (80.00±5.00)mmHg(1 mmHg=0.133 kPa)in the experimental group,those of which were(154.20±7.16), (87.00±3.81)mmHg in the control group,the differences were statistically significant (t=-2.628,-2.490,P<0.05).At 6 months after intervention,the blood pressure(systolic pressure/diastolic pressure)of the patients were(141.60±6.43),(76.00±4.85)mmHg in the experimental group,those of which were(151.60± 5.94),(85.40±4.56)mmHg in the control group,the differences were statistically significant (t=-2.555,-3.158,P<0.05).There were differences in systolic and diastolic pressure in patients with different groups at different time,and the differences were statistically significant(F=18.668,18.174,P<0.01).The total score of self-efficacy at 3 months and 6 months after intervention was(30.14±0.43),(32.56±0.23)points in the experimental group and (28.14 ± 0.15), (29.40 ± 0.19) points in the control group, the difference was statistically significant(t=9.736, 23.819, P<0.05). The differences in the total score of patients′self-efficacy in different groups at different time had statistically significance (F=2 631.551, P<0.01). Conclusions The WeChat+family centered health intervention model can significantly improve the self-efficacy of the elderly patients with high blood pressure in the General clinic.

Objective To evaluate clinical significance of the grade of ischemia by QRS complex on the admission electrocardiogram(ECG)to predict severe arrithmia in patients with acute ST-segment elevation myocardial infarction(STEMI).Methods Patients with acute ST-segment elevation myocardial infarction(STEMI)admitted to emergency department from July 2003 to April 2008 were enrolled.A total of 223 patients met the criteria(ischemic chest pain ≥ 30 min,2 or more adjacent leads of ST segment elevation and onset time within 12 h).Exclusion criteria were bundle branch block and left ventricular hypertrophy.All enrolled patients were divided into two groups based on the enrollment electrocardiogram:grade 2 ischemia(ST elevation without terminal QRS distortion; n =134)and grade 3 ischemia(ST elevation with terminal QRS distortion; n =89).Patients of the two groups had comparable genderproportion,average age and coronary heart disease risk factors etc.All patients received thrombolytic therapy.The incidence rate of ST segment resolution(STR)and severe arrithmia in hospital stay were observed.Numerical variables were expressed mean ± standard deviation and compared by unpaired Student't test,Categorical variables were expressed percentage and compared by chi square test.Multiple logistic regression analysis was used to determine independent predictors of severe arrithmia.Results Patients with grade 3 ischemia had greater Σ ST on admission and 2 h after thrombolysis ECGs(P < 0.01),the incidence rate of STR in patients with grade 3 ischemia was lower than that in patients with grade 2 ischemia(P <0.01).The peak creatine kinase MB fraction was higher in patients with grade 3 ischemia than that in patients with grade 2 ischemia(P < 0.01).There was no significant difference of the incidence of severe arrithmia,such as ventricular premature beat,ventricular tachycardia or fibrillation,second-degree or third-degree atrioventricular block,and sinus arrest between the two groups(P > 0.05),but there was a trend of higher incidence of severe arrithmia in patients with grade 3 ischemia compared with that in patients with grade 2 ischemia.Multiple logistic regression analysis demonstrated that the independent predictors of severe arrithmia were duration from symptom to thrombolysis and initial.Σ ST,whereas grade 3 ischemia remained a strong predictor of severe arrithmia.Conclusions Grade 3 ischemia on admission is associated with lower incidence of STR in patients with ST-segment elevation myocardial infarction(STEMI)after thrombolysis and a strong predictor of severe arrithmia.

ABSTRACT

Aim To investigate the effect of racemic-doxazosin(rac-DOX),S-doxazosin(S-DOX) and R-doxazosin(R-DOX) on the proliferation of vascular smooth muscle cells(VSMCs) of the rat aorta.Methods VSMCs of the rat aorta were cultured,MTT assay was used to determine the cell proliferation and the morphological changes in VSMCs were analyzed using Giemsa's staining.Results The treatment with rac-DOX,S-DOX or R-DOX at 3~30 ?mol?L-1 for 96 h inhibited the proliferation of VSMCs significantly.However,the inhibitory effect of S-DOX on cell proliferation was more potent than that of R-DOX at the same concentration(P

ABSTRACT

Objective To investigate the effects of (?)doxazosin [(?)DOX] and its enantiomers on the myocardial morphology,cell cycle and cell apoptosis in rabbits fed with high fat diet. Methods Male New Zealand white rabbits were fed with high fat diet for 4 weeks. Forty such rabbits with hyperlipemia were then divided into atherogenic diet group (model),model + (-)doxazosin [(-)DOX] group,model + (+)doxazosin [(+)DOX] group and model + (?)DOX group (10 each). Another 10 rabbits were included as normal control group. In those drug-treated groups,1.0mg/kg of doxazosin or its enantiomers were intraperitoneally administered for 9 weeks; rabbits in normal control group and atherogenic diet group were given sterile distilled water. Percentages of myocardial cells in G0/G1 phase and in S phase,proliferation index (PI) and apoptotic rate of myocardial cells were compared among the groups,and the effects of doxazosin and its enantiomers were evaluated. Results Of the animals in atherogenic diet group,the proportion of myocardial cells in G0/G1 phase increased significantly (P0.05). No histomorphological alterations were observed in myocardial cells of the rabbits in normal control group. Pathological changes in myocardial cells were observed in the rabbits of atherogenic diet group,such as vacuolar degeneration,fatty degeneration,focal myocardial necrosis,myocardial fibrosis and focal lymphocyte infiltration. The pathological changes in myocardial cells were significantly ameliorated in the animals in (-)DOX and (?)DOX group,but aggravated in the rabbits of (+)DOX group. Conclusions A long term treatment with (-)DOX in the rabbits may improve the histopathological changes in myocardial cells caused by high fat diet. (-)DOX and (+)DOX may have a optical selective effect.
