Objective: To investigate the use of mobile fitness application (APP) and healthy lifestyles of college students, so as to provide a theoretical basis for improving the health quality of college students and promoting the national scientific fitness. Methods: From August to October 2023, 591 college students from three universities in Jinan and Weifang Cities, Shandong Province were selected by stratified cluster random sampling method, and the online questionnaire was conducted on the mobile fitness APP use behavior and healthy lifestyle. The ttest and analysis of variance were used to assess the differences in healthy lifestyle of college students, and stratified linear regression was used to analyze the effect of mobile fitness APP use on healthy lifestyle. Results: The utilization rate of mobile fitness APP among college students was 82.57% (n=488), and the average score of healthy lifestyles was (3.49±0.66). The differences in students healthy lifestyle scores between different residences, grades, majors, monthly living expenses, annual personal visits, and family medical expenses were statistically significant (t/F=23.82, 4.87, 6.07, 10.17, 3.79, 16.92, P<0.05). The results of stratified regression analysis showed that the overall evaluation of mobile fitness APP, and the recommendation intention of mobile fitness phone APP were the main related factors of healthy lifestyles among college students (β=0.47, 0.06, P<0.05). Conclusions College students have a high degree of use of the mobile fitness APP, and the mobile fitness APP is positively associated with a healthy lifestyle.It should increase the publicity and promotion of mobile fitness APP to promote college students to develop a healthy lifestyle.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Chronic liver diseases, including chronic hepatitis, autoimmune liver disease, alcoholic liver disease, cirrhosis, fatty liver disease, drug-induced liver injury and so on, are common and important disorders in China. A hospital-community-patient-family integration management model for chronic liver diseases has been implemented since 2018 in Shuangshuinian Community Health Service Center collaborated with Sichuan Provincial People′s Hospital. Patients were taken care by general practitioners in the community health center under the guidance of hospital specialists, and with the active participation of patients and their family. This article introduces this integrated management model and the preliminary accomplishment to provide a reference for the management of patients with chronic liver diseases in the community.

Objective:To survey the status of illness and consultation within two weeks among residents in a community in Chengdu.Methods:A multi-stage stratified random sampling was used to carry out a questionnaire survey among the residents in a community in Chengdu during March to April 2019. The disease status, disease severity and consultation within two weeks were surveyed, and influencing factors of two-week illness were analyzed with logistic regression.Results:Among 2 714 participants, 715 had illness (900 times) within two weeks, with a two-week prevalence rate of 26.3%. The main symptoms were dizziness (6.4%, 58/900), cough (6.2%, 56/900), lumbago and leg pain (4.9%, 44/900), palpitations (3.3%, 30/900) and headache (3.1%, 28/900). The three most common diseases were hypertension (38.3%, 345/900), diabetes (19.3%, 174/900) and common cold (6.4%, 58/900). In this survey, the rate of two-week in bed was 20.6‰(56/2 714), and the rate of two-week off work was 4.8‰(13/2 714). Age, gender, education level and work status were the influencing factors of the illness in two weeks ( P<0.05). The choice of medical institution was also different among residents. Conclusion:The survey suggest that primary care should focus on the key groups of residents in the community such as elderly, women, low education level, retirement and unemployed; and it is necessary to strengthen the primary care institutions and two-way referral system of health care.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.

Objective: To understand the awareness and influencing factors of medical healthcare APP among female college students in Weifang, and to provide references for healthy lifestyle and health literacy improvement. Methods: A total of 891 female college students were selected by stratified random sampling method, and were investigated regrading awareness on medical and health care APP and associated factors. Data were statistically analyzed by composition ratio, CHI-square test and binary Logistic regression. Results: There were 54.6% of the female college students who reported not aware of medical healthcare APP. The overall awareness rates of medical and health care APP for freshmen,sophomores, juniors, seniurs and above were 39.75%,45.59%,55.78% and 52.56%, respectively, and the difference was statistically significant(χ2=16.43，P<0.05). Logistic regression analysis showed that medical costs, medical healthcare information attention, medical health care information recognition, consulting the treatment scheme were positively associated with awareness of health care APP(OR=1.40,1.51,1.27,1.33,P<0.05). Conclusion The awareness rate of medical health care APP of female college students in Weifang is relatively low,and the difference between different groups is obvious. It is necessary to improve the scientific knowledge rate of the female college students to the APP, so as to influence the life style of the female college students.

To prevent and control the epidemic of coronavirus disease 2019 (COVID-19), the community health service center should take the initiative to cooperate with sub-district office and police station to form a joint working team. Taking the advantages of professional expertise and using service contract system, the general practitioners can publicize the epidemic prevention knowledge and self-protection methods among community residents; and also take door-to-door inspection to make the decision of home isolation, centralized isolation, fever clinic visit or transfer to the designated hospital for observation and treatment. During the COVID-19 epidemic, we should give full play to the enthusiasm initiative of the community, general practitioners and residents to implement prevention and control measures and to ensure the health and safety of the people.

Family physicians contracted service is an important choice to deepen the reform of China′s healthcare reform and achieve the strategic goal of " health for all" . In order to effectively promote the contracted service, the central government has successively issued a number of policy documents, which are echoed by the localities in their proactive explorations, achieving remarkable results. But there are also multiple roadblocks hindering the contracted service to progress. This article referred to the three-circle theory and studied policy implementation from the three dimensions of policy value, policy resources, and policy impetus. A thorough analysis of the problems in the implementation process revealed such main problems as insufficient family physicians, inadequacy of supporting policies and low level of policy acceptance among the young healthy age groups. The follow-up work will promote the long-term implementation of the family physicians contracted service policy by enriching the family physicians team, enriching supporting policies, and focusing on promotions to key age groups.

The healthcare plus aging care is a new type of aging care model that integrates medical services and aging care services. China has successively issued a series of policies, encouraging the localities to proactively explore such a model. The authors refer to the four dimensions of exchange and communication, policy resources, policy executor preferences and organizational structure in the Edwards policy execution model, for analyzing the implementation of such a policy. The study found such constraints for the policy as follows: unclear policy implementation standards, inadequate policy resources of manpower, financial and material resources, differences in preferences among local governments, general hospitals, primary medical institutions, and pension institutions, as well as decentralized and restricted organizational structures. At present, the policy of healthcare plus aging care remains in the stage of exploration and trial. The government should continue to define and revise the policy to ensure the smooth progress and long-term implementation of the policy of healthcare plus aging care.
