Objective To investigate the clinical,imaging,and pathological manifestations of myofibroma in children.Methods The data of 31 patients with myofibroma confirmed by pathology were analyzed retrospectively,and the imaging features were observed.Results Among the 31 cases,28 cases were treated with subcutaneous painless mass.There were 28 cases of single lesions and 3 cases of multiple lesions.There were 5 cases with calcification,13 cases with cystic degeneration,and 12 cases with capsules.The enhanced scan showed mild to moderate progressive enhancement in 8 cases,obvious uniform/uneven enhancement in 11 cases(obvious peripheral enhancement in 5 cases),and no obvious enhancement in 2 cases.Among them,26 cases were subcutaneous type,mainly manifested as subcutane-ous round mass,with uniform or uneven density/signal,and the enhancement was mainly mild to moderate progressive enhancement or obvious enhancement.There were 3 cases of intraosseous type,mainly manifested as expansive bone destruction,without periosteal reaction and sclerotic edge,with uniform density/signal and obvious enhancement.There were 2 cases of visceral type,mainly with obvious uneven mass enhancement.Conclusion The imaging findings of myofibroma are characteristic,especially the subcutaneous and intraosseous types,which are highly consistent with pathology.Preoperative imaging examination can clearly show the size,number,enhancement and visceral involvement of the lesions.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

BackgroundFunctional near-infrared spectroscopy （fNIRS） is a new generation of imaging tool that can be used to assist the diagnosis of psychiatric disorders. However， whether the patterns of prefrontal cortex activation observed by fNIRS are specific for different psychiatric disorders remains to be explored. ObjectiveTo investigate the characteristics of prefrontal cortex activation in patients with depression， anxiety disorder， bipolar disorder and schizophrenia in verbal fluency task （VFT） using fNIRS. MethodsFrom September to December 2021， 39 patients with schizophrenia， 205 patients with depressive disorder， 212 patients with anxiety disorder and 77 patients with bipolar disorder meeting the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） were recruited in the outpatient and inpatient department of West China Hospital， Sichuan University. fNIRS was used to monitor the prefrontal cortex hemodynamic changes of patients under VFT， and the clinical symptoms of patients were assessed by Symptom Checklist 90 （SCL-90） and Hypomania Checklist-32 items（HCL-32）. Differences in mean oxyhemoglobin （HbO₂） concentration and the initial slope from 2 to 7 second during VFT were compared among patients with different diseases， and the correlation between mean HbO₂ concentration/initial slope and clinical symptoms was analyzed by partial correlation analysis. ResultsThe concentration of HbO₂ in channel 4 （Z=2.828， P=0.028） and channel 6 （Z=2.912， P=0.022） in patients with depression were significantly higher than those in patients with schizophrenia. Patients with anxiety had significantly higher changes in mean HbO₂ concentration in channel 4 （Z=3.154， P=0.010）， channel 5 （Z=3.021， P=0.015）， channel 6 （Z=2.980， P=0.017） and of all channels （Z=2.881， P=0.024） than those of schizophrenia patients. There was a statistically significant difference in the initial slope of channel 3 between patients with depressive disorder and those with bipolar disorder （Z=2.691， P=0.039）. Among patients with bipolar disorder， the anger-hostility scores of SCL-90 were negatively correlated with the mean HbO₂ concentration changes in channel 4 （r=-0.505， P=0.004）， channel 6 （r=-0.390， P=0.004）， channel 15 （r=-0.546， P=0.002）， channel 16 （r=-0.550， P=0.002） and the mean HbO₂ concentration changes of all channels （r=-0.491， P=0.006）. ConclusionPatients with schizophrenia had lower activation in frontopolar and orbitofrontal region than patients with depression and anxiety disorder， and the initial slope of the right frontopolar， inferior frontal and orbitofrontal region in patients with depression is higher than patients with bipolar disorder. In addition， patients with bipolar disorder had less activation in the frontopolar and orbitofrontal lobe， the insular cover of Broca's area and the upper outer frontal cortex， and were more irritable and hostile. ［Funded by 1·3·5 Project for Disciplines of Excellence-Clinical Research Incubation Project， West China Hospital， Sichuan University （number， ZYJC21083）］
