Depression is a severe mental illness. Although existing antidepressant medications have shown efficacy in many patients, a significant proportion show poor responses to current treatments, necessitating the need for novel therapeutic approaches. Photobiomodulation (PBM), an emerging physical therapy, has recently shown promising efficacy in the treatment of depression, as indicated by two systematic reviews, and is characterized by high safety and good tolerability. However, challenges remain in areas such as light delivery techniques and optimization of treatment parameters. This review summarizes the antidepressant mechanisms of PBM, various methods of light transmission, and recent research progress on its application in the treatment of depression. It also discusses issues related to safety, tolerability, and impact of specific parameters, aiming to provide insights and recommendations for future research on PBM as a therapy for depression.

Objective To define the conceptual connotation of network dynamic collaboration capacity in medical surge response and construct its theoretical model.Methods A mixed concept analysis method was employed,integrating multidisciplinary literature and collecting empirical evidence through semi-structured expert interviews to extract the concept of network dynamic collaboration capacity in medical surge response.By integrating complex systems,network science,synergetics,and dynamic capability theory,and combining the interview results,the study used the analogy of flood control in hydraulic engineering to develop a"network-dynamic-collaboration"triangular capacity theoretical model.Results It reveals one antecedents(sudden external shocks have led to an abnormal and continuous surge in medical demand),six core attributes(information interconnection accessibility,dynamic resource adaptability,risk perception responsiveness,multi-party collaborative interactivity,service process adaptability elasticity,and learning iterative evolution),and four consequences(mitigation of crowding risk,protection of service continuity,minimization of crisis spillover,and enhancement of system resilience)for the network dynamic collaboration capacity in medical surge response.The theoretical model elucidates the coupling mechanisms among network structural resilience,dynamic regulation processes,and collaborative co-evolution in resisting medical surge.Conclusion The new concept and theoretical model proposed in this study deepen the understanding of medical surge response system mechanisms and offer a theoretical framework and practical guidance for strengthening the full-chain resilience of health emergency systems.

Objective:To investigate the current situation of general practitioners' occupational pressure in Heilongjiang Province, and explore its relationship with professional identity and perceived organizational support. It aims to provide references for the construction of general practitioners and the development of general medical education.Methods:The general situation questionnaire, perceived organizational support scale, occupational pressure scale, and professional identity scale were applied through network and site surveys for collecting data. A total of 288 questionnaires were collected with 263 valid questionnaires (91.3%). Pearson correction analysis and bootstrap analysis were performed for data analysis.Results:The average score of occupational pressure among general practitioners was (115.95±22.40), and the results of Pearson correction analysis showed that perceived organizational support was negatively correlated with occupational pressure ( r=-0.413, P<0.01) and positive correlation with professional identity ( r=0.587, P<0.01). There were also significant negative correlations between professional identity and occupational pressure ( r=-0.442, P<0.01). Moreover, the mediating effect showed that professional identity had a certain mediating effect on the relationship between perceived organizational support and occupational pressure (LLCI=-0.2039, ULCI=-0.0760, P<0.05). Conclusion:General practitioners' occupational pressure was at a high level, which can be reduced through improving the perceived organizational support and professional identity.

Objective:To evaluate the status of nursing workplace violence experience and work performance, and analyze the mediating effects of workplace mindfulness between nurses' performance and workplace violence experience.Methods:The convenience sampling method was used. From March to May 2016, the Workplace Violence Questionnaire, Job Performance Scale, and Workplace Mindfulness Scale were used to investigate workplace violence, work performance, and workplace mindfulness encountered by 776 nurses in eight provinces of China. Correlation analysis and mediation effect analysis methods are used to analyze the relationship between the three, and the mediating effects of workplace mindfulness.Results:A total of 776 questionnaires were collected and 696 valid questionnaires. The Workplace Violence Questionnaire Score of 696 nurses was (1.21±0.78) , the score of Workplace Mindfulness Scale was (4.74±0.63) , and the score of Job Performance Scale was (3.77±0.96) . Pearson correlation analysis showed that nurses' work performance was positively correlated with workplace mindfulness ( r=0.235, P<0.01) ; nursing workplace violence was associated with work performance ( r=-0.098, P<0.05) , and workplace mindfulness ( r=-0.217, P<0.01) was negatively correlated with nursing workplace violence. The total effect of workplace violence on job performance was (β=-0.130 6, P<0.01) . Workplace mindfulness played a mediating role between the two, and the mediating effect was -0.067 5. Conclusions:Violence experienced by patients and their families in the workplace can undermine nurses' professional immersion, alertness, and organizational acceptance levels, thereby restricting the performance of nursing work. Increasing the training of nurses in the prevention of violence and interventions in response to violence are of great significance.

Objective To examine the current situation of the career plateau among anesthesiologists and analyze the impact of occupational stressors on it. Methods A questionnaire survey was conducted on the anesthesiologists. A total of 300 questionnaires were distributed and 278 questionnaires were effectively collected. Statistical analysis using SPSS 19.0 was performed to assess the status quo of career plateau among anesthesiologists. Pearson correlation analysis and stepwise regression analysis were used to analyze the influence of occupational stressors on career plateau . Results The average value of occupational stressors among anesthesiologists was (3.22±0.55), and the average value of career plateau was (3.90±0.70). Occupational interest in the occupational stressors of anesthesiologists is negatively correlated with the occupational plateau (r=-0.552, P<0.01), and career development is negatively correlated with occupational plateau (r=-0.541, P<0.01) as well. Both occupational interest and career development show a negative predictive effect on the career plateau (β=-0.359, P<0.01 andβ=-0.334, P<0.01, respectively). Conclusion Career plateau among anesthesiologists is at a medium-to-high level. Occupational interest and occupational development in occupational stressors have a negative predictive effect on occupational plateaus, so hospital managers should pay attention to them.

Objective To explore what kind of role serum interleukin 6 (IL-6) and interleukin 18 ( IL-18) play in the relationship between type D personality and acute coronary syndrom (ACS)prognosis.Methods Serum levels of IL-6,IL-18 in all 214 ACS patients were measured with ELISA.According to the scores of type D personality scale(DS14) ,the subjects were divided into the group with type D personality (50 cases)and the one without type D personality ( 164 cases).The serum IL-6 and IL-18 level between the two groups were detected and analyzed.Results There were 23.36% ACS patients with type D personality.The serum IL-6, IL-18levels of the group with type D in ACS acute stage and ACS recovery stage were (2.340 ± 0.081 )OD, (2.016 ±0.023 ) OD and ( 1.460 ± 0.070 ) OD, ( 1.313 ± 0.012 ) OD respectively, significantly higher than those of the group without type D (2.178 ± 0.180)OD, ( 1.849 ± 0.159)OD and ( 1.387 ± 0.091 )OD, ( 1.196 ± 0.132 ) OD respectively(P＜0.01).Conclusion At home and abroad ,there are similar amount of ACS patients with type D personality.The high serum IL-6 and IL-18 levels may play an important role in pathogenesis of relationship between type D personality and ACS poor prognosis.
