Two courses teaching has been in difficult situation in colleges for a long time.Most colleges raise the two courses teaching by way of social practice.However the class is the main channel in the two courses teaching.So only by strengthening the appeal of class teaching and inspiring college students' study enthusiasm can we improve their cognition and thinking ability and unify their thoughts.Thus the class can become the main channel of university students' ideological and political education actually.

Disasters are traumatic events that are always incongruent with our existing cognitive structures. Immediate negative psychological impact and traumatic related psychiatric disorders are popular among survivals involving the disasters. Super-half of survivals involving the "5" 12" Wenchuan earthquake experienced the symptoms of anxiety or increased arousal. 12.59% of survivals were met with the ASD diagnosis. 21.29% of adults and 10.21% of adolescents were met with the PTSD diagnosis 5 months after the major earthquake. Immediately negative psychological impact and high prevalence of traumatic related psychiatric disorders among survivals were confirmed.More effort should be paid on the disaster related patients in emergency department with psychiatric issues. Also, the long-term psychological service is necessary for Sichuan Pest-Disaster Reconstruction Projects.

Objective:To explore the effect of mobile health (mHealth) management system on dietary behavior of patients with coronary heart disease (CHD) .Methods:Using the convenient sampling method, CHD patients who were hospitalized in Department of Cardiology of Beijing Anzhen Hospital and Beijing Chaoyang Hospital of Capital Medical University were selected as the research objects from June 2019 to January 2020. The research objects were randomly divided into the intervention group and the control group using SAS software. Finally, 68 cases in the intervention group and 66 cases in the control group completed the study. The intervention group received mhealth management, while the control group received routine management, and they were followed up to 1 month after discharge. The proportion of patients with the low-salt and low-oil diet, the intake of salt, oil, staple food, vegetables, fruits, fish, shrimp, poultry and eggs, BMI and blood pressure were compared between the two groups.Results:At 1 month follow-up, the intervention group was better than the control group in terms of low salt and low oil diet, salt intake, oil intake and vegetable intake compliance, and the differences were statistically significant ( P<0.05) . At 1 month follow-up, there were no statistically significant differences in BMI and blood pressure between two groups ( P>0.05) . Conclusions:The mobile health system can effectively increase the proportion of patients with a low-salt and low-oil diet, and improve the intake compliance of salt, edible oil and vegetables in patients with CHD. In future studies, the intervention time should be extended to further explore the long-term intervention effect of mobile health and give full play to the role of mobile health in continuous behavior management of patients with CHD after discharge.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Since December 2019, novel coronavirus pneumonia (NCP) has been reported in Wuhan, Hubei Province, and spreads rapidly to all through Hubei Province and even to the whole country. The virus is 2019 novel coronavirus (2019-nCoV), never been seen previously in human, but all the population is generally susceptible. The virus spreads through many ways and is highly infectious, which brings great difficulties to the prevention and control of NCP. Based on the needs of orthopedic trauma patients for emergency surgery and review of the latest NCP diagnosis and treatment strategy and the latest principles and principles of evidence-based medicine in traumatic orthopedics, the authors put forward this expert consensus to systematically standardize the clinical pathway and protective measures of emergency surgery for orthopedic trauma patients during prevention and control of NCP and provide reference for the emergency surgical treatment of orthopedic trauma patients in hospitals at all levels.
