Objective To systematically evaluate the effect of early rehabilitation activities on diaphragm function in patients with mechanical ventilation.Methods Computerized system search databases included PubMed,Embase,Web of Science,Cochrane Library,China Biology Medicine disc,China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,and VIP on the effects of early rehabilitation activities on diaphragm function in patients with mechanical ventilation.The search period was from the creation of the database to March 2025.Two researchers independently performed literature screening,literature quality evaluation,and data extraction.Results 9 papers,including 902 patients,were finally included.Meta-analysis showed that early rehabilitation activities improved diaphragm inspiratory thickness[standard mean difference(SMD)=0.67,95％CI:0.39-0.95,P＜0.000 01],diaphragm expiratory thickness(SMD=0.39,95％CI:0.16-0.63,P=0.0001),diaphragm thickness fraction(SMD=0.76,95％CI:0.58-0.94,P＜0.000 01)and diaphragm excursion(SMD=0.49,95％CI:0.27-0.72,P＜0.000 01),and reduced the incidence of patient failure to withdraw from the machine(relative risk=0.45,95％CI:0.31-0.65,P＜0.0001).Conclusion Early rehabilitation activities can improve diaphragm function in patients with mechanical ventilation,which has good clinical value and is worth standardized promotion and application in intensive care unit;The intervention strategy should be further refined in the future to improve the prevention and treatment strategy of diaphragm dysfunction.

Schizophrenia is a debilitating mental disorder with complex etiology. Early identification of high-risk individuals and early intervention for early-stage patients can help improve prognosis, but effective identification methods are lacking. In recent years, research on proteomic techniques based on peripheral blood has achieved certain advancements in exploring the etiology of schizophrenia, as well as in early recognition and diagnostic modeling. This paper provides a review of the research methodologies of peripheral blood-based proteomics and the candidate biomarkers identified through these method.

The patient was a 25-year-old male who initially presented with emotional issues and later developed involuntary movements following the use of antipsychotic and antidepressant medications. He was initially misdiagnosed with Tardive Dyskinesia, a condition commonly associated with psychotropic drugs. However, due to the severity of his involuntary movements, the ineffectiveness of treatment, and a notable family history, genetic testing was performed. The test indicated a mutation in the VPS13A gene of the patient, and provided evidence for a final diagnosis of Chorea Acanthocytosis. This case report aims to enhance the recognition of movement disorders among psychiatrists and facilitate earlier identification of neurological diseases whose primary manifestation is involuntary movement.

Objective:This study aimed to investigate the effects of glucagon-like peptide-1 receptor agonists(GLP-1RAs) on the emotional behaviors in wild-type mice and explore the underlying mechanisms.Methods:The study consisted of two parts.(1) Drug effect evaluation: C57BL/6 mice were randomly assigned to saline, semaglutide, or liraglutide groups. After 4 weeks of continuous subcutaneous administration, anxiety-like behaviors were evaluated by the open field tests and elevated plus maze, and depression-like behaviors were assessed by the forced swimming test and tail suspension test. Neurotransmitter levels, including NE, DA, 5-HT, GABA, and glutamate, were measured in target brain regions using LC-MS/MS. Hypothalamic activation subregions were identified by c-fos immunohistochemistry.(2) Time-course analysis: Mice received short-term administration(2 weeks), long-term administration(4 weeks), or drug withdrawal(assessed 4 weeks post-withdrawal). Behavioral performance, hypothalamic neurotransmitter levels, and plasma adrenocorticotropic hormone and corticosterone were measured.Results:Compared with the saline group, both GLP-1RAs significantly prolonged immobility time in the forced swimming and tail suspension tests. Multiple brain regions exhibited neurotransmitter abnormalities, including marked reductions in hypothalamic norepinephrine, dopamine, and γ-aminobutyric acid levels. Both GLP-1RAs significantly increased c-fos positive cell counts in the suprachiasmatic nucleus and arcuate nucleus of the hypothalamus. Time-course analysis revealed that short-term administration did not induce depressive phenotypes, whereas long-term administration led to depression-like behaviors, which recovered after drug withdrawal. Plasma adrenocorticotropic hormone and corticosterone levels were elevated even after short-term treatment and remained high after drug withdrawal, while hypothalamic neurotransmitter abnormalities normalized upon withdrawal.Conclusion:GLP-1RAs induce depression-like behaviors in a time-dependent manner, with neurotransmitter imbalance and persistent hyperactivation of the HPA axis likely contributing to the pathophysiological mechanism.
