Objective:To explore the value of subspecialty group collaboration combined with disease checklist-driven learning in overcoming the impact of the specialized disease treatment mode in subspecialty establishment on the cultivation of professional postgraduate students.Methods:In the teaching of general surgery and gastroenterology, sixty professional postgraduate students of grade 2019 were randomly divided into control group and experimental group, with 30 students in each group. The control group received traditional teaching, while the experimental group received the teaching mode of subspecialty group collaboration combined with disease checklist-driven learning. The teaching effectiveness and the degree of satisfaction with teaching were compared between the two groups. The data were analyzed using the t test and the chi-squared test using SPSS 20.0. Results:In actual teaching, compared with the control group, the experimental group showed significantly higher scores of theoretical assessment (71.51±11.32 vs. 87.23±10.51, P<0.05) and case analysis (73.61±6.82 vs. 92.37±6.87, P<0.05). The rates of satisfaction with theoretical knowledge learning, application of clinical thinking ability for diseases, teaching organization forms, and teaching effectiveness were 90.00%(27/30), 86.67%(26/30), 96.67%(29/30), and 93.33%(28/30) in the experimental group, respectively, which were significantly higher than those of the control group [40.00%(12/30), 23.33%(7/30), 40.00%(12/30), and 46.67%(14/30), respectively; all P<0.05]. Conclusions:The subspecialty group collaboration combined with disease checklist-driven learning mode can overcome the problems of "narrow disease spectrum and narrow knowledge scope" in specialized postgraduate education, and guide students to break the teaching barriers generated by subspecialty construction to create a new form of comprehensive and multi-disease learning, with good prospects for promotion and application.

OBJECTIVE To compare the components of volatile oil from Gardenia jasminoides and their liver protective effect before and after stir-frying with wine. METHODS Steam distillation was used to exact the volatile oil from G. jasminoides and wine stir-fried G. jasminoides. The components of volatile oil were identified by GC-MS method， and the relative mass fraction of each component was calculated by peak area normalization method. The rats were randomly divided into normal group， model group， positive control group （bifendate suspension 35 mg/kg）， G. jasminoides low-dose and high-dose groups [1， 2 g/kg （calculated by crude drug）] and wine stir-fried G. jasminoides low-dose and high-dose groups [1， 2 g/kg （calculated by crude drug）] with 10 rats in each group. Liver injury model was established by intraperitoneal injection of 40% carbon tetrachloride in rats of each group after continuous intragastric administration of corresponding drug solution for 7 days. The status， serum biochemical indexes， liver biochemical indexes and liver pathological sections of rats in each group were compared. RESULTS Twenty-three volatile oil components from G. jasminoides and 25 volatile oil components from wine stir-fried G. jasminoides were identified； there were 18 common volatile oil components， of which the contents of 17 common components were decreased， while the content of one common component was increased due to stir-frying with wine. Compared with model group， the symptoms of depression and liver cell damage of rats in each administration group were improved to varying degrees； the serum levels of adenosine deaminase， alanine transaminase， aspartate transaminase， direct bilirubin， lactate dehydrogenase，prealbumin， total bile acid and total bilirubin were significantly decreased， while the total protein level was significantly increased； the level of malondialdehyde in liver tissue was significantly decreased， there were statistical significance （P＜0.05 or P＜0.01）. CONCLUSIONS During stir-frying with wine， the contents of 17 volatile oil components are decreased， while the content of one volatile oil component is increased. Wine stir-fried G. jasminoides shows liver protective effect. .

To explore the potential associations between perceived stress and health-promoting behaviors based on the theoretical schema of the middle-range theory of adaptation to chronic illness. From January to May 2021, a convenience sampling method was used to recruit 230 young and middle-aged patients with metabolic syndrome who underwent physical examination in the inpatient center of Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. The Health-Promoting Health Profile-Ⅱ, Chinese Perceived Stress Scale, Coping and Adaptation Processing Scale-Short Form, and Multi-dimensional Scale of Perceived Social Support were used in the cross-sectional study. The chain mediation effect procedure and bootstrap sampling test were used to examine the mediating role of adaptability and social support between perceived stress and health-promoting behaviors. The mean score of health-promoting behaviors was 100.0±14.6, the mean score of perceived stress was 22.0± 6.9, the mean score of adaptability was 47.0±6.1, and the mean score of social support was 63.8±10.8. Perceived stress had a negative impact on patients' health-promoting behaviors (=-0.309, <0.05). The adaptability (effect size= -0.112, 95%:-0.199~-0.038) and social support (effect size= -0.032, 95%:-0.083~played a mediating role and a chain mediating role in the process of perceived stress influencing patients' health-promoting behaviors (effect size= -0.045, 95%:-0.093~-0.020). Adaptability and social support play an intermediary role between perceived stress and health-promoting behaviors in young and middle-aged patients with metabolic syndrome. Healthcare professionals can motivate patients to develop healthy behaviors by developing intervention strategies on adaptability and social support.
