Studies have suggested that the nucleus accumbens (NAc) is implicated in the pathophysiology of major depression; however, the regulatory strategy that targets the NAc to achieve an exclusive and outstanding anti-depression benefit has not been elucidated. Here, we identified a specific reduction of cyclic adenosine monophosphate (cAMP) in the subset of dopamine D1 receptor medium spiny neurons (D1-MSNs) in the NAc that promoted stress susceptibility, while the stimulation of cAMP production in NAc D1-MSNs efficiently rescued depression-like behaviors. Ketamine treatment enhanced cAMP both in D1-MSNs and dopamine D2 receptor medium spiny neurons (D2-MSNs) of depressed mice, however, the rapid antidepressant effect of ketamine solely depended on elevating cAMP in NAc D1-MSNs. We discovered that a higher dose of crocin markedly increased cAMP in the NAc and consistently relieved depression 24 h after oral administration, but not a lower dose. The fast onset property of crocin was verified through multicenter studies. Moreover, crocin specifically targeted at D1-MSN cAMP signaling in the NAc to relieve depression and had no effect on D2-MSN. These findings characterize a new strategy to achieve an exclusive and outstanding anti-depression benefit by elevating cAMP in D1-MSNs in the NAc, and provide a potential rapid antidepressant drug candidate, crocin.

OBJECTIVE To evaluate the effectiveness and safety of sequential therapy with parathyroid hormone analogues and bisphosphonates for osteoporosis. METHODS PubMed， Embase， the Cochrane Library， Web of Science， China National Knowledge Infrastructure， VIP， Wanfang data， and SinoMed were searched in both English and Chinese databases from their inception to March 25， 2024. Two researchers independently conducted literature searches， screening， and data extraction. Review Manager 5.4 software was used for the meta-analysis. Subgroup analyses and sensitivity analyses were performed based on different medication sequences in the treatment group to account for potential sources of heterogeneity. RESULTS A total of 7 randomized controlled trials involving 2 461 participants were included， with 1 215 in the treatment group and 1 246 in the control group. The meta-analysis results showed that the treatment group using sequential therapy with parathyroid hormone analogues and bisphosphonates had superior effects on improving bone mineral density at the lumbar spine [SMD＝0.90， 95%CI （0.44， 1.35）， P＜0.001]， total hip [SMD=0.68， 95%CI （0.14， 1.21）， P＝0.01]， and femoral neck [SMD＝0.45， 95%CI （0.04， 0.86）， P＝0.03] compared to the control group. It also significantly outperformed the control group in reducing the incidence of fractures post- treatment [OR＝0.72， 95%CI （0.54， 0.97）， P＝0.03].significant difference was noted in the incidence of adverse reactions between the two groups [OR＝1.21， 95%CI （0.99， 1.46）， P＝0.06]. Subgroup analysis based on intervention measures in the treatment group showed that switching from bisphosphonates to parathyroid hormone analogues [SMD＝0.56， 95%CI （0.09， 1.03）， P＝0.02] or switching from parathyroid hormone analogues to bisphosphonates [SMD＝0.97， 95%CI （0.49， 1.46）， P＜0.001] both significantly potentiated lumbar spine bone mineral density compared to the control group. Switching from bisphosphonates to parathyroid hormone analogues also significantly promoted total hip bone mineral density compared to the control group [SMD＝0.66， 95%CI （0.18， 1.13）， P＝0.007]. Sensitivity analysis indicated that the results of this study were robust. CONCLUSIONS Sequential therapy with parathyroid hormone analogues and bisphosphonates can be recommended as an effective treatment for patients with osteoporosis， with good safety profiles. The medication sequences should be individually adjusted based on the patient’s particular situation and the different responses of various skeletal sites.

Objective To investigate the popularization of cardiopulmonary resuscitation(CPR)knowledge and science popularization needs among urban and rural residents in Tonghai County,Yuxi City,Yunnan Province,so as to explore the establishment of an efficient and appropriate science popularization model.Methods A total of 300 residents aged 15-60 years old were selected from Tonghai County,Yuxi City,Yunnan Province using stratified and simple random sampling methods.A self-designed questionnaire was used to conduct an anonymous questionnaire survey.Results Only 20.3%of Tonghai County residents master CPR skills,and 26.2%of Tonghai County residents have never heard of CPR.There is a statistically significant difference in the awareness rate of CPR between rural residents and non-rural residents(P<0.01).There are differences in residents'age and CPR awareness(P<0.01),the age and CPR are inversely proportional.The residents have a higher willingness to perform chest compressions and mouth-to-mouth resuscitation on strangers,66.2%and 68.6%respectively.63.79%of residents have never attended relevant training.But 92.76%of the people said they were willing to participate in the relevant training when they learned the training news.Conclusion Residents in Tonghai County generally lack knowledge of CPR first aid,but the demand for first aid knowledge of residential CPR is high and the attitude towards rescue is positive.It is recommended that relevant departments increase CPR science popularization and training efforts,and popularize CPR into villages.

Pressure injury is a kind of chronic wound that is difficult to heal in clinical practice. The healing process often fails to proceed smoothly, which is one of the difficult problems in the field of clinical wound repair. At present, the wound treatment method has developed rapidly and has an obvious curative effect on stage 1 and 2 pressure injuries. There are fewer treatments for stage 3 and 4 pressure injuries, and surgical treatment is often used. However, surgical treatment has the risk of superimposed injury, which may aggravate the condition. In addition, the treatment effect needs to be improved. It is necessary to explore high-quality, minimally invasive, and low-cost solutions to solve this problem. This article reviews the definition, classification, formation mechanism, clinical manifestations, influencing factors, and treatment methods of pressure injury, aiming to provide a reference for the clinical treatment of pressure injury wounds.

Objective:To compare the therapeutic effects of intramedullary nail fixation, simple tibial plate fixation, and tibial plate + posterior-to-anterior screw fixation in the surgical treatment of lower 1/3 spiral fracture of the tibia combined with posterior malleolar fracture.Methods:A retrospective study was conducted to analyze the clinical data of 78 patients with lower 1/3 spiral fracture of the tibia combined with posterior malleolar fracture who had been treated at Department of Orthopedics, The Hospital Affiliated to Qingdao University from June 2015 to June 2022. There were 46 males and 32 females with an age of (48.9±14.6) years. The patients were divided into 3 groups according to their fixation methods. Group A (18 patients) underwent simple intramedullary nail fixation, group B (40 patients) simple tibial plate fixation, and group C (20 patients) tibial plate fixation for tibial fractures and posterior-to-anterior screw fixation for posterior malleolar fractures. The operation time, intraoperative blood loss, fracture union time, postoperative complications, as well as ankle-hindfoot scores of American Orthopaedic Foot and Ankle Society (AOFAS) and Baird-Jackson scores at pre- and post-operation were compared among the 3 groups.Results:The differences in the preoperative baseline data were not statistically significant among the 3 groups, indicating comparability ( P>0.05). All patients were followed up for (24.9±10.1) months. The fracture union time in Group A was 14.0(13.0, 14.0) weeks, significantly longer than that in groups B and C [13 (13, 14) weeks] ( P<0.05). The AOFAS ankle-hindfoot score and Baird-Jackson score at the last postoperative follow-up in all patients were better than those before surgery ( P<0.05). The AOFAS ankle-hindfoot scores at the last follow-up in groups B and C [95.5 (86.0, 96.0) points and 96.0 (89.5, 98.5) points] were significantly higher than that in group A [86.5 (78.0, 93.0) points] ( P<0.05), and the Baird-Jackson scores at the last follow-up in groups B and C [93.0 (88.8, 95.0) points and 95.0 (91.0, 98.0) points] were also significantly higher than that in group A [86.0 (78.0, 89.5) points] ( P<0.05). All the 7 cases of complications (3 ones of poor fracture union and 4 ones of anterior knee pain) were observed in group A. Conclusion:In the surgical treatment of lower 1/3 spiral fracture of the tibia combined with posterior malleolar fracture, tibial plate fixation and tibial plate + posterior-to-anterior screw fixation can achieved better therapeutic effects than intramedullary nail fixation.

Neurodegenerative diseases are often associated with inflammatory mechanisms, where persistent or excessive inflammatory responses can lead to neuronal damage and subsequent pathological changes. In acute neurological conditions such as stroke or traumatic brain injury, inflammation is a key factor that triggers acute neuronal injury and long-term sequelae. In chronic neurodegenerative diseases, including Alzheimer's disease, cognitive dysfunction, Parkinson's disease, and multiple sclerosis, the chronic activation of inflammation is closely related to gradual degeneration of neurons. Resolvin D1 (RvD1), an endogenous pro-resolving mediator, plays a crucial role in controlling the intensity and duration of inflammation by inhibiting excessive activation of immune cells, modulating the release of pro-inflammatory cytokines, and maintaining the integrity of the blood-brain barrier. This review focuses on the mechanisms of RvD1 in mediating inflammatory damage in major neurological diseases, aiming to provide theoretical support for a deeper understanding of disease mechanism, optimized therapeutic strategies, and enhanced outcome.

As an adjuvant alternative therapy， phototherapy is widely used for early diagnosis and late treatment of breast cancer due to its non-invasive treatment characteristics. But the application of phototherapeutic agents has been limited in the clinic due to poor hydrophobicity and tissue targeting， low photostability， and obvious toxic side effects in vivo. With the development of nanotechnology， new composite nano-phototherapy agents have emerged. This paper summarizes the latest developments and findings of new composite nano-phototherapy agents for phototherapy in the field of breast cancer treatment in the past 5 years. With the development of multifunctional nanomaterials in the field of breast cancer imaging diagnosis and treatment， the modified phototherapy agent achieved further development respectively from improving light response to improve the light thermal conversion or increasing the generation of reactive oxygen species， targeting tumor microenvironment， immune cells and cancer cell surface receptors to achieve drug controllable response release， using biomimetic materials and endogenous substances to improve biocompatibility. Although phototherapeutic agents exhibit high cell-killing rates in the treatment of metastatic breast cancer models and effectively inhibit their recurrence and metastasis， problems remain regarding the safety and compatibility of synergistic therapy. Future studies can not only improve the existing effects of phototherapeutic agents， but also develop oral drugs with more convenient routes based on immunotherapy to amplify the immune response and resist breast cancer through multiple routes.
