Objective To observe the structure of cognitive injury and the effect of psychologic behavior training on cognitive function in community chronic schizophrenic patients. Methods80 healthy adults (control group) and 76 community chronic schizophrenia patients (research group) were assessed with World Health Organization-battery of cognitive assessment instrument for elderly (WHO-BCAI), mini-mental state examination (MMSE), and activities of daily living (ADL) pre- and post-psychologic behavior training. ResultsThere were significant differences in the scores of WHO-BCAI, MMSE, ADL between control group and research group (P<0.05 or P<0.01). 12 months after training, all the scores of research group significantly improved compared with that before training (P<0.05 or P<0.01). ConclusionCognitive disorders have occurred in the community chronic schizophrenia patients in wide range. Psychologic behavior training can improve their cognitive function.

Objective To study the role of Lugol staining for detecting early esophageal cancer and precancerous lesions.Methods 2% Lugol solution was adopted to stain esophageal mucosa in 45 cases with esophageal suspicious lesions,observed and multiple biopsies were taken for pathological study.Results Thirty-nine cases were light or non-stained among the 45 cases with Lugol staining.Which revealed 8 esophageal cancers(5 early cancer,3 advanced cancer),5 Barrett esophagus,,11 mild-moderate dysplasias.The rate of detecting early esophageal cancer and precancerous lesions with Lugol staining was 46.7%.Conclusion Lugol staining is helpful for diagnosis of early esophageal cancer and precancerous lesions,and it is simple in operating.The role of Lugol staining in detecting early esophageal cancer and precancerous lesions has important clinical value.

Objective To investigate the diagnostic value of EUS with miniprobe on upper gastrointestinal tract mesenchymal tumor(GIMT).Methods The EUS features of 38 patients with GIMT who underwent EUS with miniprobe were studied retrospectively,and the results were compared with the postoperative pathological findings.Results Among 38 GIMT cases detected by EUS,there were 25 cases of gastrointestinal stromal tumor,11 cases of leiomyoma,and 2 cases of leiomyosarcoma.Postoperative histopathological and immunohistochemical examinations confirmed 28 cases of stromal tumor.In which 6 cases were high-risk GIST,8 cases were leiomyoma,1 case was leiomyosarcoma,and 1 case was neurofibroma.The accuracy of diagnosis with EUS was 89%.Conclusion EUS is an accurate method in diagnosis of submucosal tumors,which can make better differentiation diagnosis between GIMT and other submucosal tumors.

Objective:To investigate the current status of satisfaction with training program and loyalty to the university among professional postgraduate students majoring in clinical medicine, as well as the association between satisfaction with training program and loyalty to the university.Methods:The 2017 National Medical Student Satisfaction Survey Database was used. A total of 1 944 professional postgraduate students in the second or third year, as well as those with delayed graduation, from 59 postgraduate training colleges and universities who participated in clinical internship were selected. SPSS 20.0 software was used for analysis; descriptive analysis was used to describe satisfaction with training program and loyalty to the university; factor analysis was adopted to calculate comprehensive satisfaction score to reduce the number of variables; logistic regression analysis was applied to investigate the association of general information and satisfaction with training program with loyalty to the university.Results:The professional postgraduate students majoring in clinical medicine had a degree of 60.44% of loyalty to the university. Satisfaction with training program reflected low satisfaction at each link of the training program. For every 1-point increase in the comprehensive satisfaction scores of the four links of courses, research training, college support, and practice, the loyalty to the university was increased to 2.11, 1.83, 1.77, and 1.75 times as the original, respectively, of the baseline scores.Conclusion:There is still room for further improvement in the satisfaction with training program and the loyalty to the university among professional postgraduate students majoring in clinical medicine, and the satisfaction with training program is closely associated with the loyalty to the university. Colleges and universities need to take measures for courses, practice, research training, and college support, so as to improve satisfaction and thus enhance loyalty to the university.

Objective To analyze the current status of research competitiveness of medical subjects in China.Methods Analyzing the fund of Natural Science Foundation of China (NSFC) in 2017 and using the Range ratio and Theil Index to describe the dispersion and source of difference.Regional research competitiveness of Chinese medical subjects is measured by the attraction and accumulation capacity of NSFC.Results The research competitiveness of medical subjects in East China and South China are stronger,and those in the Northwest are weaker.The distribution of medical funds mainly originated from the interior (88.88％),among which the East China and North China are the two regions with the largest contribution rate.In terms of provinces,Shanghai and Beijing have a much higher concentration of medical funds than other provinces.Condusions The Research competitiveness in inter-regional medical subjects in China is quite different,and the differences mainly stem from the competition of internal provinces;the degree of advantages of medical subjects in regions is different,and there are medical research centers in ever regions.

Objective:To review the funding status of the National Natural Science Foundation of China in the field of preventive medicine, summarize the characteristics of approved funding for sub-disciplines and institutions, to further analyze the effects of funding distribution.Methods:Descriptively analyze the funding status of the National Natural Science Foundation of China in the field of preventive medicine from 2010 to 2019, and analyze its aggregation effect by constructing a single funding strength and intensity index.Results:The project number, funding amount and number of research institutions have shown an overall upward trend. In the past 10 years, a total of 1.683 billion has been approved for funding, and the proportion in the Department of Health Sciences has remained at about 4%. Non-communicable disease epidemiology, human nutrition, and health toxicology are among the top three in terms of project number, funding amount, and number of grantee institutions. Sub-discipline funding is uneven, showing a phenomenon of development differentiation. The amount of approved funding, the number of institutions, and the strength of individual funding for universities are significantly higher than those of scientific research institutions and CDCs. The total amount of Top 10 funding accounted for 41.49%, which obviously showed a " head" effect.Conclusions:The Natural Science Foundation of China should continue to increase investment in the field of preventive medicine. Key breakthroughs in dominant disciplines, weaker disciplines make up for shortcomings, guide universities, research institutes, and CDCs to carry out inter-institutional project cooperation based on their respective advantages, and encourage interdisciplinary research to enhance discipline innovation capabilities.

The development of medical and health services calls for a harmonious doctor-patient relationship. From the perspective of education, good communication is a positive factor in building a harmonious doctor-patient relationship ecology. The action path to strengthen the ideological and political construction of the doctor-patient communication course is the need to cultivate high-quality medical students, which is conducive to the ideological and political education of medical students and the teaching effect of the doctor-patient communication course. To improve the ideological and political construction system of the doctor-patient communication course, efforts should be made in four dimensions: strengthen the ideological and political quality of teachers, excavate and make good use of ideological and political elements of the doctor-patient communication course, enhance the dominant and recessive dual educational narration, form a joint force mechanism for the ideological and political system of the doctor-patient communication course.
