OBJECTIVETo study the effects of total alkaloids of Rubus alceaefolius (RAP) on non-alcoholic fatty liver disease (NAFLD) rats and explore its possible mechanisms.
METHODSixty SD rats were randomly divided into six groups: control group, model group, compound methionine and choline bitartrate tablets (CMCB)group and three RAP groups treated respectively with low, middle and high dose of RAP. The NAFLD model was induced by feeding fat-rich food. NAFLD rats were administrated with 0.35 g x kg(-1) CMCB and 0.36, 0.72, 1.44 g x kg(-1) RAP for 4 weeks respectively. The weight index of liver was measured. Hepatic histolog ical changes were observed. The concentration in serum of aspartate amino transferase (AST), alanine amino tranferase (ALT), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were determined. The mRNA expressions of SOD, MDA, TNF-alpha and IL-6 in hepatic tissue were detected.
RESULTCompared with the model group, degree of steatosis of hepatic lobule was improved, the weight index of liver was decreased, serum levels of ALT, AST, TNF-alpha and IL-6 were significantly lower in the high and middle dose RAP group (P < 0.05 or P < 0.01). The levels of SOD and MDA in hepatic tissue were lower in the high dose RAP group (P < 0.05). The mRNA expressions of TNF-alpha and IL-6 in hepatic tissue were decreased (P < 0.05 or P < 0.01).
CONCLUSIONRAP can protect liver in experimental NAFLD, and its possible mechanisms may be concerned with clearing the oxygen free radical, reducing the product of lipid peroxidation, inhibiting the release of inflammatory cytokines and reducing nflammatory response.

Based on the teaching concept of constructivism, this study aims to promote independent inquiry-based learning and clinical thinking among students and establish the guiding ideology of "full participation, process control, in-depth discussion, and expansion of thinking". A blending learning model was adopted with offline inquiry-based group learning and in-class defense and comment, as well as online teacher-student interaction and supervision to promote learning. Case-problem-based learning (CPBL) of pathophysiology was carried out among the medical students in the class of 2017, and process management was strengthened to effectively manage the two key links of data retrieval and group discussion. The analysis of 176 teaching evaluations collected at the end of the semester show that in terms of the overall evaluation of CPBL teaching, 162 students (92.05%) had high evaluation on teaching objectives, organization, cases, and personal gains and held a very or relatively favorable attitude. There were more negative feedbacks on "appropriate time allocation"; 21 students (11.93%) held a relatively or very disapproving attitude, and 149 students (84.66%) "felt very tired". In terms of teaching effect evaluation, 150 students (85.23%) strongly or relatively agreed that CPBL teaching may help to understand professional knowledge, stimulate learning enthusiasm and initiative, improve problem solving ability, emphasize clinical practice to cultivate clinical thinking, supervise and promote learning, and enhance team cooperation and teacher-student communication. In terms of the evaluation of teachers, 167 students (94.89%) thought that teachers were rigorous, responsible, and enthusiastic in teaching, attached importance to process management, and did well in effective guidance and thinking inspiration (strongly or relatively agree). The above results suggest that the CPBL teaching reform of pathophysiology based on process management can effectively promote in-depth inquiry-based independent learning and the cultivation of clinical thinking and improve teaching effectiveness, but further improvement is needed for teaching arrangement and time allocation.

Objective:To understand the status of supervision of mental health service industry in Shanghai, and to provide reference for further strengthening the construction of mental health service system in Shanghai. Methods: In Shanghai, 107 mental health service agencies (including psychiatric institutions, non-specialist medical institutions, non-specialist enterprise and public institutions, social institutions) were selected from Shanghai psychological service industry association. The survey was conducted with the Questionnaire on Current Situation of Mental Health Professional Service Agencies in Shanghai (agency survey), including the "relevant information of agency" and the "management of the agency in the field of mental health services"(whether the agency had supervision requirements on the mental health service personnel, whether the agency organized supervision, the source of supervisors and payment method), and the Questionnaire on Current Situation of Mental Health Service Professionals in Shanghai (professional survey), including "basic information on demography "and" psychological professional work" (the number of hours of supervision in 2015, the cost of supervision, and the form of supervision and payment method). These two parts of questionnaire were selected and analyzed. Results: Agency survey results showed that 80% of non-specialist enterprises had no supervision requirements for mental health service personnel, supervisor in non-specialist medical institutions were mainly from psychiatric institution (52.9%). The cost of supervision in most psychiatric institutions was paid by the agency (39.1%) and the cost of supervision in most public institutions was paid by professional (37%). The professional institutions under the jurisdiction of other departments within the unit required less supervision of the professional staff than the independent institutions (P < 0.001). Professional survey results showed that the number of supervision hours of mental health service professional in social institutions was more than that in the other three types of institutions (P <0.001), of which 47.9% chosen to pay the cost of supervision by themselves. The proportion of their own payment in social institutions was higher than that in the other three types of institutions (P <0.001). Conclusion:The social institutions in Shanghai have the best supervision of social institutions, followed by the supervision of the medical institutions. The supervision of non-medical enterprises and their personnel needs to be improved.
