ObjectiveTo explore the present national status of diagnostic teaching as well as to investigate the opinions on teaching operation such as overall course planning, so as to provide references for the formulation of national diagnostic teaching standard in the future.MethodsSelf-made questionnaires were adopted to carry out an anonymous survey among the teachers from 50 different medical colleges and universities who worked on diagnostic teaching throughout the country from October 2016 to September 2017.ResultsA total of 100 teachers were investigated. The diagnostic teaching departments where 59 respondents worked in were formed by a few fixed teachers plus teachers in rotation. The requirement of rotation time as well as the setting up of lecture-internship ratio in each school were quite various. Forty-seven respondents agreed that the ideal lecture-internship ratio should be internship more than lecture. As for the instruments of clinical skill room, only 40% of the respondents agreed that their diagnostic departments were equipped with a steady standardized patient (SP) team, which was also the reason why SP teaching was the least utilized teaching method during internship (47%). The respondents had various opinions on whether the final exam should weigh more than 50% in the subject score. Above these, the planning and expectations of the respondents on diagnostic course were mostly in consensus.ConclusionsThe development of diagnostic course including teaching staff, teaching content and teaching condition, etc. among each medical colleges and universities was not balanced. It’s quite necessary to formulate a unified and reasonable standard to normalize the teaching staff constitution, teaching planning and set-up as well as teaching condition so as to guarantee the teaching quality.
Objective To investigate the effect of cleft palate on the development of the mid-part of the face so as to provide an optimum animal model for the fetal cleft repair. Methods Twenty female Boer hybrid goats were selected, aging from 8 to 12 months and weighing from 35 to 55 kg. The mating day was identified as 0 day of pregnancy. The goats werediagnosed with pregnancy by the B-ultrasound examination at 30 days, and were allocated into experimental group (n=14) and control group (n=6). In experimental group, uterine cavitory operation was performed at 65 days of pregnancy to form cleft palate which was a fissure between oral and nasal cavity; no treatment was given as the control group. At 120 days of pregnancy, and after 1 month and 3 months of birth, the gross observation and 3-dimensional skull CT reconstruction were performed; and the maxillary bone width named as PPMM and the maxillary bone length named as APMM were measured. Results After operation, 2 goats died of infection, miscarriage occurred in 3 goats; 9 goats were included into the experiment. The operation success rate was 64.3%. In experimental group, maxillary dysplasia occurred in all the fetal goats at 120 days of pregnancy, and more obvious maxillary dysplasia was observed at 1 month and 3 months after birth; no maxillary dysplasia occurred in control group. There were significant differences in PPMM and APMM between 2 groups at different time points (P lt; 0.05). In experimental group, the lambs had poor chewing function, and died of pulmonary infection after aspiration at 1-4 months after birth. Conclusion The surgical procedure for partial ablation of secondary primitive palate in the midl ine could make the model of cleft palate.
ObjectiveTo investigate the network structure of comorbid depression and anxiety symptoms among medical staff and analyze differences across institutional types. MethodsA convenience sampling method was used to select medical staff from medical institutions at various levels in Guang'an City as participants between August 10 and 15, 2024. General demographic questionnaires, the Chinese version of the Patient Health Questionnaire (PHQ-9) for depression screening, and the Chinese version of the Generalized Anxiety Disorder Scale (GAD-7) were used to survey them. The study aimed to analyze the influencing factors of anxiety and depression and construct a network model. Predictability, bridging strength, and node strength were used to assess the network structure. The non-parametric bootstrap method was employed to evaluate the accuracy and stability of the network, and finally, a Network Comparison Test (NCT) was used to examine the impact of different levels of healthcare institutions on the network model. ResultsA total of 889 participants were included in the study. The analysis showed that the incidence of depressive symptoms (PHQ-9≥5) among healthcare workers was 44.88%, while the incidence of anxiety symptoms (GAD-7≥5) was 43.98%, with a comorbidity rate of 36.67%. Network analysis revealed that the top three symptoms with the highest node strength were difficulty relaxing (A4), excessive worry (A3), and fatigue (D4). The top three symptoms with the highest bridging strength were irritability/anger (A6), fatigue (D4), and worrying about terrible things happening (A7). The different levels of healthcare institutions did not have a significant impact on the network model. ConclusionThe central symptoms (such as difficulty relaxing, excessive worry, and fatigue) and key bridging symptoms (such as irritability/anger, fatigue, and worrying about terrible things happening) in the anxiety and depression symptom network can serve as potential intervention targets for healthcare workers at risk of depressive and anxiety symptoms.
