Objectives To analyze the effect of improved oven for defluorination in coal-burning endemic fluorosis areas in China, and to provide evidence for the prevention and control of fluorosis. Methods Electronic databases including CNKI, CBM, VIP and CDMD-D (1989 to 2005), were searched. We also checked the reference lists of relevant articles. We selected relevant articles according to the predefined inclusion and exclusion criteria. The methodological quality was assessed . Data on room heat preservation and the effect of improved oven for defluorination were collected in the surveillance spots of Three Gorges Reservoir. Correlation analyses were conducted between the improved oven and its effect parameters. Results Twelve articles of low quality met the selection criteria, of which 9 were graded C and 3 were graded D in terms of the methodological quality. A negative correlation was found between the decreasing rate of normal oven use and the decreasing rate of dental fluorosis as well as of urine fluorine (Pearson correlation coefficient r = – 0.87, – 0.63, Plt;0.01, lt;0.05, respectively). Analysis also revealed a positive correlation between room heat preservation and the decreasing rate of dental fluorosis as well as of normal oven use (the two Spearman correlation coefficients and P values were the same: r = –1.00, Plt;0.01). Conclusion High-quality studies on the effect of improved oven for defluorination in China are not available. Based on the current evidence, the improved oven for defluorination and the correct use, maintenance and house rebuilding for heat preservation may help to prevent fluorosis.
Objective To investigate the latest development of tissue engineeredregenerative medicine in industrialization, with the intention to direct work in practical area. Methods A complete insight of regenerative medicine in industrialization was obtained through referring to update publications, visiting related websites, as well as learning from practical experience. Results The aerial view of the future of regenerative medicine was got based on knowledge of four different tissue engineering projects. Conclusion All present efforts should be devoted to regenerative medicine area meeting the industrialized trends.
Recent studies have introduced attention models for medical visual question answering (MVQA). In medical research, not only is the modeling of “visual attention” crucial, but the modeling of “question attention” is equally significant. To facilitate bidirectional reasoning in the attention processes involving medical images and questions, a new MVQA architecture, named MCAN, has been proposed. This architecture incorporated a cross-modal co-attention network, FCAF, which identifies key words in questions and principal parts in images. Through a meta-learning channel attention module (MLCA), weights were adaptively assigned to each word and region, reflecting the model’s focus on specific words and regions during reasoning. Additionally, this study specially designed and developed a medical domain-specific word embedding model, Med-GloVe, to further enhance the model’s accuracy and practical value. Experimental results indicated that MCAN proposed in this study improved the accuracy by 7.7% on free-form questions in the Path-VQA dataset, and by 4.4% on closed-form questions in the VQA-RAD dataset, which effectively improves the accuracy of the medical vision question answer.
Objective To assess the effectiveness of the course of “Being a Friend with Patients”. Methods There were three parts in this course: (1) To experience what the empathy was, by counseling activities; (2) To accompany patients in hospital; (3) To share the experience after accompanying. There were 118 participants who were freshmen at the end of 2005. Results and Conclusions According to feedback from the students, they understand empathy and how the patients feel after the counseling. The course is accepted by all students. It may help students to be more attentive to and concerned about their patients, and to provied help for them.
ObjectiveTo investigate the capability and demands of medical students of medical information retrieval, and to provide information for medical information literacy education.MethodsWe conducted an online questionnaire survey among medical students from 15th to 21st July, 2019, aiming to analyze basic characteristics of the subjects and their ways and capability to acquire medical information, and evaluated their demands and satisfaction about relevant courses.ResultsFour hundred and nine valid questionnaires were collected. The average age of the respondents was (21±3) years old. Among the respondents, 279 (68.2%) were female, 290 (70.9%) were undergraduates, and 187 (45.7%) majored in clinical medicine. The mostly accessed ways to obtain medical information were textbooks (87.8%) and search engines (84.4%). Among Chinese literature databases, the most commonly used was China National Knowledge Infrastructure (67.7%), followed by Wanfang (54.3%). As for English literature databases, the most commonly used was PubMed (66.0%), while the proportions of respondents who used other databases was less than 1/4. As for the problems when obtaining information, 84.8% of the respondents supposed that no access to some online databases was the main problem. Obtaining information from search engine scored the highest [(3.21±1.00) points, 5 points totally] when they were asked to self-evaluate their ability to obtain medical information by different methods. In terms of training demands, the need for courses about literature authenticity and accuracy evaluation was the highest [(4.05±1.07) points, 5 points totally]. The trainings were expected to be conducted within 1-2 years after enrollment (83.9%). Training through professional courses (86.8%) was the most welcomed training form, followed by courses on MOOC (51.3%), an online course platform. More than 50% of the respondents were satisfied with the current relevant courses and trainings.ConclusionBoth the students’ capability of medical information retrieval and the design of relevant trainings should be improved to better prepare the medical students for further clinical practice and scientific research.
It has always been an important policy of the Chinese government to provide aid and assistance for the development of Tibet. With nearly one-eighth of China’s total land areas and about 0.002% of China’s total population, the Tibet Autonomous Region lags behind the domestic average level in medical education and is in bad need for medical professionals. The West China Center of Medical Sciences (WCCMS) of Sichuan University has managed to introduce US projects to set up the West China–Tibet Telemedical Education System to transmit medical courses in a real-time and interactive way. Based on this system, WCCMS has established a model for assisting the Tibet University Medical College through transmitting medical courses, training their medical faculty, sending WCCMS faculty to work in Tibet and admitting medical teachers and students from Tibet to study and be trained at West China Medical School and Hospital.
ObjectiveTo investigate scientific research situation of postgraduates in the West China School of Medicine of Sichuan University. MethodsA self-designed questionnaire was used in an investigation concerning scientific research situation among 352 medical postgraduates in the West China Medical School of Sichuan University. Then SPSS 15.1 software was used to analyze the data. ResultsMost experiments, that the postgraduates took, involved multiple technologies, of which, molecular techniques were the most widely-used (reaching 35.5%). Sixty-eight percent students maintained that clinical practice, teaching/learning and scientific research were very important. The most frequently-encountered problem were research design, experimental techniques and methods, the contact with laboratory, and statistical analysis. When encountering the problems, 51.1% postgraduates turned to tutors, and 40.1% dealt with it by themselves. ConclusionIt is suggested that, cultivating scientific research ability and awareness of medical postgraduates should be strengthened, and platforms should be set up for medical postgraduates to carry out research.
