A longitudinal examination of the measurement properties and invariance of the Sleep Condition Indicator in Chinese healthcare students.

BACKGROUND: The Sleep Condition Indicator (SCI), an insomnia measurement tool based on the updated Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria with sound psychometric properties when applied in various populations, was evaluated here among healthcare students longitudinally, to demonstrate its measurement properties and invariance in this particularly high-risk population. METHODS: Healthcare students of a Chinese university were recruited into this two-wave longitudinal study, completing the simplified Chinese version of the SCI (SCI-SC), Chinese Regularity, Satisfaction, Alertness, Timing, Efficiency, Duration (RU_SATED-C) scale, Chinese Patient Health Questionnaire-4 (PHQ-4-C), and sociodemographic variables questionnaire (Q-SV) between September and November 2022. Structural validity, measurement invariance (MI), convergent and discriminant validity, internal consistency, and test-retest reliability of the SCI-SC were examined. Subgroups of gender, age, home location, part-time job, physical exercise, and stress-coping strategy were surveyed twice to test cross-sectional and longitudinal MI. RESULTS: We identified 343 valid responses (62.9% female, mean age = 19.650 ± 1.414 years) with a time interval of seven days. The two-factor structure was considered satisfactory (comparative fit index = 0.953-0.989, Tucker-Lewis index = 0.931-0.984, root means square error of approximation = 0.040-0.092, standardized root mean square residual = 0.039-0.054), which mostly endorsed strict invariance except for part-time job subgroups, hence establishing longitudinal invariance. The SCI-SC presented acceptable convergent validity with the RU_SATED-C scale (r ≥ 0.500), discriminant validity with the PHQ-4-C (0.300 ≤ r < 0.500), internal consistency (Cronbach's alpha = 0.811-0.835, McDonald's omega = 0.805-0.832), and test-retest reliability (intraclass correlation coefficient = 0.829). CONCLUSION: The SCI-SC is an appropriate screening instrument available for assessing insomnia symptoms among healthcare students, and the promising measurement properties provide additional evidence about validity and reliability for detecting insomnia in healthcare students.

Deep learning pneumoconiosis staging and diagnosis system based on multi-stage joint approach.

BACKGROUND: Pneumoconiosis has a significant impact on the quality of patient survival due to its difficult staging diagnosis and poor prognosis. This study aimed to develop a computer-aided diagnostic system for the screening and staging of pneumoconiosis based on a multi-stage joint deep learning approach using X-ray chest radiographs of pneumoconiosis patients. METHODS: In this study, a total of 498 medical chest radiographs were obtained from the Department of Radiology of West China Fourth Hospital. The dataset was randomly divided into a training set and a test set at a ratio of 4:1. Following histogram equalization for image enhancement, the images were segmented using the U-Net model, and staging was predicted using a convolutional neural network classification model. We first used Efficient-Net for multi-classification staging diagnosis, but the results showed that stage I/II of pneumoconiosis was difficult to diagnose. Therefore, based on clinical practice we continued to improve the model by using the Res-Net 34 Multi-stage joint method. RESULTS: Of the 498 cases collected, the classification model using the Efficient-Net achieved an accuracy of 83% with a Quadratic Weighted Kappa (QWK) score of 0.889. The classification model using the multi-stage joint approach of Res-Net 34 achieved an accuracy of 89% with an area under the curve (AUC) of 0.98 and a high QWK score of 0.94. CONCLUSIONS: In this study, the diagnostic accuracy of pneumoconiosis staging was significantly improved by an innovative combined multi-stage approach, which provided a reference for clinical application and pneumoconiosis screening.

Arthritis in Children with Psychiatric Deteriorations: A Case Series.

Pediatric acute-onset neuropsychiatric syndrome (PANS), pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections, Sydenham chorea, and other postinfectious psychiatric deteriorations are thought to be caused by inflammatory/autoimmune mechanisms, likely involving the basal ganglia based on imaging studies. Patients have a relapsing-remitting course and some develop severe refractory psychiatric disease. We found that 55/193 (28%) of consecutive patients meeting PANS criteria developed chronic arthritis and 25/121 (21%) of those with related psychiatric deteriorations developed chronic arthritis. Here we describe 7 of these patients in detail and one sibling. Many of our patients often have "dry" arthritis (no effusions found on physical exam) but subtle effusions detected by imaging and features of spondyloarthritis, enthesitis, and synovitis. Joint capsule thickening, not previously reported in children, is a common finding in the presented cases and in psoriatic arthritis in adults. Due to the severity of psychiatric symptoms in some cases, which often overshadow joint symptoms, and concomitant sensory dysregulation (making the physical exam unreliable in the absence of effusions), we rely on imaging to improve sensitivity and specificity of the arthritis classification. We also report the immunomodulatory treatments of these 7 patients (initially nonsteroidal anti-inflammatory drugs and disease-modifying antirheumatic drugs with escalation to biologic medications) and note any coincidental changes to their arthritis and psychiatric symptoms while on immunomodulation. Patients with overlapping psychiatric syndromes and arthritis may have a unifying cause and pose unique challenges; a multi-disciplinary team can utilize imaging to tailor and coordinate treatment for this patient population.

The influence of perceived parenting styles on socio-emotional development from pre-puberty into puberty.

The relative impact of parenting on socio-emotional development of children has rarely been examined in a longitudinal context. This study examined the association between perceived parenting styles and socio-emotional functioning from childhood to adolescence. We hypothesized that optimal parenting associated with improvement in socio-emotional functioning from childhood into early adulthood, especially for those with more behavioral problems in childhood. Children between ages 7 and 9 years were recruited for the Singapore Cohort Study of Risk Factors for Myopia (SCORM). Nine years later, 700 out of 1052 subjects were followed up (67%). During childhood, parents completed the Child Behavior Checklist (CBCL), while young adults completed the Youth Self-Report (YSR) and Parental Bonding Instrument (PBI). Perceived optimal parental care resulted in less internalizing and externalizing problems in early adulthood in comparison to non-optimal parental care styles. Perceived optimal paternal parenting, but not maternal parenting, in interaction with childhood externalizing problems predicted externalizing symptoms in early adulthood. No significant interactions were found between perceived parenting styles and internalizing problems. In conclusion, perceived parental care associates with the quality of socio-emotional development, while optimal parenting by the father is especially important for children with more externalizing problems in childhood.

A qualitative study to explore views of patients', carers' and mental health professionals' to inform cultural adaptation of CBT for psychosis (CBTp) in China.

BACKGROUND: The evidence for effectiveness of Cognitive Behaviour Therapy (CBT) is robust and the national organizations in the United Kingdom and the United States recommend its use. It is not utilized to its full potential in low and middle-income countries. Adaptation of CBT treatment to the target culture may facilitate its uptake. This study explored views of patients with schizophrenia, their caregivers, and mental health professionals for the purpose of cultural adaptation of CBT. METHOD: The project was conducted in a teaching hospital in China. Systematic content and question analysis were the techniques we used to analyse the data generated in a series of qualitative interviews (N 45) in China. After identification of emerging themes and categories we compared and contrasted the themes across different interviews recursively. Triangulation of themes and concepts was undertaken to compare further and contrast the data from the different participating groups. RESULTS: This work highlighted the barriers in therapy as well as opportunities for use of CBT in that environment. Patients and their carers in China use a bio-psycho-spiritual-social model of illness. CBT is not commonly used to help those with schizophrenia in China. CONCLUSIONS: This study will facilitate the therapists using CBT for people with psychosis in China. These results require to be tested in clinical trials.

Mechanism of flavonoids in the treatment of gouty arthritis (Review).

The present review expounds the advancements in the application and mechanisms of flavonoids in gouty arthritis, highlighting their significance in managing the disease. Gouty arthritis is among the most common and severe inflammatory diseases, caused by hyperuricemia and the deposition of sodium urate crystals in the joints and surrounding tissues, posing a serious threat to human life and health. Flavonoids, extracted from various herbs, have attracted significant attention due to their efficacy in improving gouty arthritis. The present study systematically reviews the in vivo studies and in vitro animal studies on flavonoids from herbal medicines for the treatment of gouty arthritis that have been previously published in the PubMed, ScienceDirect, Google Scholar and China National Knowledge Infrastructure databases between 2000 and 2023. The review of the literature indicated that flavonoids can improve gouty arthritis through multiple mechanisms. These include lowering xanthine oxidase activity, inhibiting uric acid (UA) synthesis, regulating UA transporters to promote UA excretion, reducing the inflammatory response and improving oxidative stress. These mechanisms predominantly involve regulating the NOD­like receptor 3 inflammasome, the Toll­like receptor 4/myeloid differentiation factor 88/nuclear factor­κB signaling pathway, and the levels of UA transporter proteins, namely recombinant urate transporter 1, glucose transporter 9, organic anion transporter (OAT)1 and OAT3. Various flavonoids used in traditional Chinese medicine hold therapeutic promise for gouty arthritis and are anticipated to pave the way for novel pharmaceuticals and clinical applications.

Ameliorative action of "daitongxiao" against hyperuricemia includes the "uric acid transporter group".

This study aimed to investigate the potential mechanisms involved in the therapeutic effects of daitongxiao (DTX) on hyperuricemia (HUA). DTX was administered to two animal models of HUA via gavage feeding: HUA quail model (a uricotelic animal with urate oxidase deficiency), treated continuously for 35 days post-HUA induction, and HUA rats (an animal with active urate oxidase), treated continuously for 28 days post-HUA induction. HUA was induced in quail by administering a solution of sterile dry yeast powder via gavage feeding, while in rats, it was induced by intragastric gavage feeding of a solution of adenine and ethambutol hydrochloride. DTX improved overall health; increased bodyweight; reduced renal index, serum urate levels, serum xanthine oxidase activity, blood urea nitrogen, and creatinine; and enhanced urinary and fecal uric acid (UA) excretion in these two animal models. The results of hematoxylin and eosin and hexamine silver staining of kidney sections revealed that DTX significantly mitigated HUA-induced renal structural damage and inflammatory response. The results of quantitative real-time polymerase chain reaction, Western blotting, and immunofluorescence analyses revealed that DTX downregulated the renal expression levels of glucose transporter 9 (GLUT9) and upregulated the renal expression levels of organic anion transporters (OAT1 and OAT3) in both HUA models. Thus, the findings of this study suggest that DTX suppresses the progression of HUA by modulating the expression of the UA transporter group members.

Mechanism of DaiTongXiao in the treatment of gouty arthritis through the NLRP3 signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: DaiTongXiao (DTX) is a traditional Chinese Dai folk formulation utilized for gouty arthritis treatment, with substantial evidence supporting its anti-inflammatory properties. The NLRP3 inflammasome disorder is tightly linked to the development of many inflammatory diseases. AIM OF THE STUDY: To elucidate the therapeutic efficacy of DTX in gouty arthritis and reveal its potential underlying mechanism. MATERIALS AND METHODS: The primary active constituents in DTX were determined through ultraviolet spectrophotometry and gas chromatography. Rats underwent induction with monosodium urate (MSU), followed by treatment of J774A.1 cells with adenosine triphosphate (ATP) activation and lipopolysaccharide (LPS) induction and the subsequent culture in Dulbecco's modified Eagle's medium. The degree of foot joint swelling in rats was assessed, and ankle joints were evaluated through H&E staining. Enzyme-linked immunosorbent assay was performed to measure the levels of interleukin (IL)-1ß, IL-6, IL-8, and tumor necrosis factor (TNF)-α in both serum and cells. Reverse transcription-polymerase chain reaction (RT-PCR) was performed to determine the relative mRNA expression levels of NLRP3, ASC, Caspase-1, and NF-κB in J774A.1 macrophages. The expression of NLRP3, ASC, Caspase-1, and NF-κB was examined by western blotting. RESULTS: DTX could alleviate MSU-induced joint swelling in rats, as evidenced by a reduction in joint inflammation. Moreover, DTX effectively enhanced the survival rate of J774A.1 cells following LPS induction and ATP activation. Furthermore, DTX significantly reduced IL-1ß, IL-6, IL-8, and TNF-α levels in both cell culture medium and rat serum. RT-PCR results revealed that DTX notably downregulated the mRNA expression levels of NLRP3, ASC, Caspase-1, and NF-κB in J774A.1 cells. Additionally, DTX downregulated NLRP3, ASC, NF-κB, and Caspase-1 expression in the joint tissue. CONCLUSIONS: DTX exerts a significant anti-gouty arthritis effect, with its mechanism being tightly linked to the NLRP3 inflammatory signaling pathway. This pathway may be modulated by inhibiting IL-1ß differentiation and maturation by downregulating NLRP3, ASC, Caspase-1, and NF-κB protein expression. This, in turn, leads to a reduction in the release of IL-6, IL-8, and TNF-α, ultimately impeding gouty arthritis progression.

Contrast-enhanced Imaging in Peripheral Pulmonary Lesions: The Role in US-guided Biopsies.

Purpose To compare the tissue adequacy and diagnostic accuracy of US-guided biopsies of peripheral pulmonary lesions (PPLs) with and without contrast agents. Materials and Methods A retrospective study was conducted at four medical centers in patients with PPLs who underwent US-guided percutaneous transthoracic needle biopsy (PTNB) between January 2017 and October 2022. The patients were divided into contrast-enhanced US (CEUS) and US groups based on whether prebiopsy CEUS evaluation was performed. Tissue adequacy and the diagnostic accuracy of PTNB, stratified by lesion size, were analyzed and compared between groups. A propensity score matching (PSM) analysis was conducted using the nearest-neighbor matching method. Results A total of 1027 lesions were analyzed, with 634 patients (mean age, 59.4 years ± 13.0 [SD]; 413 male) in the US group and 393 patients (mean age, 61.2 years ± 12.5; 270 male) in the CEUS group. The CEUS group produced more acceptable samples than the US group (98.2% vs 95.7%; P = .03) and achieved higher diagnostic accuracy (96.9% vs 94.2%; P = .04), with no evidence of a difference in sensitivity (96.7% vs 94.0%; P = .06). PSM and stratified analyses (n = 358 per group) indicated higher tissue adequacy (99.0% vs 95.7%; P = .04) and diagnostic accuracy (98.5% vs 92.9%; P = .006) in the CEUS group compared with the US group for 2-7-cm PPLs but not for lesions larger than 7 cm. Conclusion PTNB with prebiopsy CEUS evaluation demonstrated significantly better tissue adequacy and diagnostic accuracy compared with US guidance alone for PPLs ranging from 2 to 7 cm, with similar biopsy performance achieved between groups for lesions larger than 7 cm.

Characterization of Lysophospholipase D Activity in Mammalian Cell Membranes.

Lysophosphatidic acid (LPA) is a lipid mediator that binds to G-protein-coupled receptors, eliciting a wide variety of responses in mammalian cells. Lyso-phospholipids generated via phospholipase A2 (PLA2) can be converted to LPA by a lysophospholipase D (lyso-PLD). Secreted lyso-PLDs have been studied in more detail than membrane-localized lyso-PLDs. This study utilized in vitro enzyme assays with fluorescent substrates to examine LPA generation in membranes from multiple mammalian cell lines (PC12, rat pheochromocytoma; A7r5, rat vascular smooth muscle; Rat-1, rat fibroblast; PC-3, human prostate carcinoma; and SKOV-3 and OVCAR-3, human ovarian carcinoma). The results show that membranes contain a lyso-PLD activity that generates LPA from a fluorescent alkyl-lyso-phosphatidylcholine, as well as from naturally occurring acyl-linked lysophospholipids. Membrane lyso-PLD and PLD activities were distinguished by multiple criteria, including lack of effect of PLD2 over-expression on lyso-PLD activity and differential sensitivities to vanadate (PLD inhibitor) and iodate (lyso-PLD inhibitor). Based on several lines of evidence, including siRNA knockdown, membrane lyso-PLD is distinct from autotaxin, a secreted lyso-PLD. PC-3 cells express GDE4 and GDE7, recently described lyso-PLDs that localize to membranes. These findings demonstrate that membrane-associated lyso-D activity, expressed by multiple mammalian cell lines, can contribute to LPA production.

The arousal effect of An-Gong-Niu-Huang-Wan on alcoholic-induced coma rats: A research based on EEG.

ETHNOPHARMACOLOGICAL RELEVANCE: Acute alcohol intoxication is one of the leading causes of coma. A well-regarded Chinese herbal formula, known as An-Gong-Niu-Huang-Wan (AGNHW), has garnered recognition for its efficacy in treating various brain disorders associated with impaired consciousness, including acute alcohol-induced coma. Despite its clinical effectiveness, the scientific community lacks comprehensive research on the mechanistic aspects of AGNHW's impact on the electroencephalogram (EEG) patterns observed during alcohol-induced coma. Gaining a deeper understanding of AGNHW's mechanism of action in relation to EEG characteristics would hold immense importance, serving as a solid foundation for further advancing its clinical therapeutic application. AIM OF THE STUDY: The study sought to investigate the impact of AGNHW on EEG activity and sleep EEG patterns in rats with alcoholic-induced coma. MATERIALS AND METHODS: A rat model of alcohol-induced coma was used to examine the effects of AGNHW on EEG patterns. Male Sprague-Dawley rats were intraperitoneally injected with 32% ethanol to induce a coma, followed by treatment with AGNHW. Wireless electrodes were implanted in the cortex of the rats to obtain EEG signals. Our analysis focused on evaluating alterations in the Rat Coma Scale (RCS), as well as assessing changes in the frequency and distribution of EEG patterns, sleep rhythms, and body temperature subsequent to AGNHW treatment. RESULTS: The study found a significant increase in the δ-band power ratio, as well as a decrease in RCS scores and ß-band power ratio after modeling. AGNHW treatment significantly reduced the δ-band power ratio and increased the ß-band power ratio compared to naloxone, suggesting its superior arousal effects. The results also revealed a decrease in the time proportion of WAKE and REM EEG patterns after modeling, accompanied by a significant increase in the time proportion of NREM EEG patterns. Both naloxone and AGNHW effectively counteracted the disordered sleep EEG patterns. Additionally, AGNHW was more effective than naloxone in improving hypothermia caused by acute alcohol poisoning in rats. CONCLUSION: Our study provides evidence for the arousal effects of AGNHW in alcohol-induced coma rats. It also suggests a potential role for AGNHW in regulating post-comatose sleep rhythm disorders.

Baiheqingjin formula reduces inflammation in mice with asthma by inhibiting the PI3K/AKT/NF-κb signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Baiheqingjin Decoction (BHQJ), which consists of 7 traditional Chinese herbs including Baibu (Stemona tuberosa Lour.), Hezi (Terminalia chebula Retz.), Mahuang (Ephedra sinica Stapf.), Ziwan (Aster tataricus L. f.), Dilong (Pheretima), Sangbaipi (Morus alba L.), and Xianhecao (Agrimonia pilosa Ledeb.). BHQJ is commonly used for treating cough asthma, and variant cough-variant asthma as it, is effective in improving asthma symptoms and reducing airway inflammation. AIM OF THE STUDY: To investigate the mechanisms of BHQJ in treating allergic asthma. MATERIALS AND METHODS: We collected information about the components and targets of 6 Chinese medicines (excluding Pheretima) from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Additionally, we obtained genes associated with asthma from six disease databases. To create a protein-protein interaction network, we conducted an intersection analysis using differentially expressed genes derived from RNA transcriptome data. Subsequently, we carried out Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. To validate the findings from network pharmacology and transcriptomics, we established an allergic asthma mouse model induced by ovalbumin and conducted in vivo experiments. RESULTS: Using network pharmacology and transcriptomics analyses, we identified the pathways including the PI3K/AKT signaling pathway, and NF-κB signaling pathway. Among these, the involvement of the PI3K/AKT/NF-κB signaling pathway in various pathological processes of asthma, such as airway inflammation, smooth muscle contraction, and excessive mucus production, are well-documented. Histopathological examinations indicated that BHQJ had the potential to mitigate inflammatory cell infiltration and the excessive growth of goblet cells in the airways of asthmatic mice, consequently reducing mucus secretion. Results from Western blot demonstrated that BHQJ could inhibit the activation of the PI3K/AKT/NF-κB pathway at the protein levels. Enzyme-linked immunosorbent assay findings revealed that BHQJ could reduce the production of typical "type 2 asthma" cytokines and immunoglobulin (Ig) E in the blood. These discoveries imply that BHQJ has the potential to reduce the release of inflammatory cytokines and suppress the overactivation of the PI3K/AKT/NF-κB signaling pathway, thus offering a therapeutic approach for asthma. CONCLUSION: Our research offers initial insights into the fundamental mechanisms through which BHQJ treats asthma. This study reveals the potential mechanism of BHQJ in treating asthma, particularly its role in reducing inflammatory cytokines, mucus production, and cell infiltration, as well as inhibiting the expression of PI3K/AKT/P65 phosphorylated protein. These findings indicate the potential of BHQJ in treating asthma. In summary, our study provides preliminary insights into the asthma treatment mechanism of BHQJ and provides guidance for future research.

Network pharmacology combined with experimental validation reveals the mechanism of action of erpixing granules on functional dyspepsia.

ETHNOPHARMACOLOGICAL RELEVANCE: Functional dyspepsia (FD) is a prevalent gastrointestinal disorder characterised by high incidence and recurrence rates, posing significant health risks. Erpixing Granules (EPX), approved by the National Food and Drug Administration in 2002, are known for their spleen and stomach invigorating properties, effectively treating FD. However, its mechanism of action remains unclear. AIM OF THE STUDY: This study aims to elucidate EPX's mechanism of treating FD through network pharmacology, and experimental validation using FD animal models. METHODS: In this study, the chemical composition of EPX in positive and negative ion modes was analyzed by UHPLC-Q-TOF MS. The mass spectral data were processed and analyzed using MS-DIAL software to automatically match compound fragment information and identify the known components with the compound database to obtain the active components of EPX. SwissTargetPrediction was used to obtain EPX targets, while FD-related targets were sourced from GeneCards, OMIM and DisGeNET databases. A protein-protein interaction (PPI) network was constructed using the STRING platform, and potential signalling pathways of EPX were determined through Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Finally, an FD model was established in rates by administering a 0.1% iodoacetamide sucrose solution, followed by tail clamp stimulation to experimentally validate the network pharmacology findings. RESULTS: Our results revealed 139 effective ingredients in EPX, targeting 60 core FD-related genes. PPI network analysis identified EGFR, CTNNB1 and NFκB1 as core target genes. The KEGG pathway analysis indicated that EPX can modulate FD progression through the PI3K/AKT signalling pathway. Animal experiments demonstrated EPX's capacity to increase body mass, food intake and food utilisation efficiency in FD rats, alongside increased gastric juice secretion, pepsin activity, trypsin activity, cholesterol, bile acid and bilirubin activity. HE examination revealed that EPX improved the inflammatory infiltration of gastric mucosal cells in rats. Furthermore, EPX also promoted gastric emptying and intestinal propulsion in mice. These results suggest that EPX improves spleen and stomach function, enhances the protective effect on the spleen and stomach and promotes food digestion and absorption. Immunofluorescence studies revealed upregulated expression of PI3K, AKT and ANO1 proteins in gastric tissue following EPX administration, while Western blotting indicated increased expression of SCF and C-kit proteins. CONCLUSION: Suggesting EPX's anti-FD effect may involve the regulation of the SCF/C-kit signalling pathway and activation of downstream PI3K/AKT signalling pathway, thereby promoting gastrointestinal motility and improving FD symptoms.

Prevalence of Neurological Soft Signs at Presentation in Pediatric Acute-Onset Neuropsychiatric Syndrome.

Importance: Studies of brain imaging and movements during REM sleep indicate basal ganglia involvement in pediatric acute-onset neuropsychiatric syndrome (PANS). Characterizing neurological findings commonly present in patients with PANS could improve diagnostic accuracy. Objective: To determine the prevalence of neurological soft signs which may reflect basal ganglia dysfunction (NSS-BG) in youth presenting with PANS and whether clinical characteristics of PANS correlate with NSS-BG. Design, Setting, and Participants: 135 new patients who were evaluated at the Stanford Children's Immune Behavioral Health Clinic between November 1, 2014 and March 1, 2020 and met strict PANS criteria were retrospectively reviewed for study inclusion. 16 patients were excluded because they had no neurological exam within the first three visits and within three months of clinical presentation. Main Outcomes and Measures: The following NSS-BG were recorded from medical record review: 1) glabellar tap reflex, 2) tongue movements, 3) milkmaid's grip, 4) choreiform movements, 5) spooning, and 6) overflow movements. We included data from prospectively collected symptoms and impairment scales. Results: The study included 119 patients: mean age at PANS onset was 8.2 years, mean age at initial presentation was 10.4 years, 55.5% were male, and 73.9% were non-Hispanic White. At least one NSS-BG was observed in 95/119 patients (79.8%). Patients had 2.1 NSS-BG on average. Patients with 4 or more NSS-BG had higher scores of global impairment (p=0.052) and more symptoms (p=0.008) than patients with 0 NSS-BG. There was no significant difference in age at visit or reported caregiver burden. On Poisson and linear regression, the number of NSS-BG was associated with global impairment (2.857, 95% CI: 0.092-5.622, p=0.045) and the number of symptoms (1.049, 95% CI: 1.018-1.082, p=0.002), but not age or duration of PANS at presentation. Conclusions and Relevance: We found a high prevalence of NSS-BG in patients with PANS and an association between NSS-BG and disease severity that is not attributable to younger age. PANS may have a unique NSS-BG profile, suggesting that targeted neurological exams may support PANS diagnosis.

Cang-ai volatile oil ameliorates imiquimod-induced psoriatic skin lesions by suppressing the ILC3s.

ETHNOPHARMACOLOGICAL RELEVANCE: Cang-ai volatile oil (CAVO) is an aromatic Chinese medicine with potent antibacterial and immune regulatory properties. While CAVO has been used to treat upper respiratory tract infections, depression, otomycosis, and bacterial infections in the skin, its effect on psoriasis is unknown. AIM OF THE STUDY: This study explores the effect and mechanism of CAVO in psoriasis intervention. MATERIAL AND METHODS: The effect of CAVO on the expression of IL-6 and IL-1ß was assessed in TNF-α-induced HaCaT cells using enzyme-linked immunosorbent assay (ELISA). Mice were given imiquimod (IMQ) and administered orally with different CAVO doses (0.03 and 0.06 g/kg) for 5 days. The levels of inflammatory cytokines related to group-3 innate lymphoid cells (ILC3s) in the skin were assessed using hematoxylin and eosin (H&E) staining, ELISA, and western blotting (WB). The frequency of ILC3s in mice splenocytes and skin cells was evaluated using flow cytometry. RESULTS: The results demonstrated that CAVO decreased the expression of IL-6 and IL-1ß in TNF-α- induced HaCaT cells. CAVO significantly reduced the severity of psoriatic symptoms in IMQ-induced mice. The expression of inflammatory cytokines in the skin, such as IL-1ß, IL-6, IL-8, IL-22, IL-23, and IL-17 A were decreased, whereas IL-10 levels were increased. The mRNA expressions of TNF-α, IL-23 A, IL-23 R, IL-22, IL-17 A, and RORγt were down-regulated in skin tissues. CAVO also decreased the levels of NF-κB, STAT3, and JAK2 proteins. CONCLUSIONS: CAVO potentially inhibits ILC3s activation to relieve IMQ-induced psoriasis in mice. These effects might be attributed to inhibiting the activation of NF-κB, STAT3, and JAK2 signaling pathways.

A study on the effectiveness of videoconferencing on teaching parent training skills to parents of children with ADHD.

OBJECTIVE: Many geographic locations are without services and staff available to provide treatment for children with attention deficit hyperactivity disorder (ADHD). This is a randomized controlled trial to evaluate the effectiveness of group parent training on ADHD treatment delivered via videoconferencing. SUBJECTS AND METHODS: Twenty-two subjects were enrolled in the study, with 9 subjects in the videoconference session (treatment group) and 13 in the face-to-face session (control group). The parent child relationship questionnaire for child and adolescents (PCQ-CA), Vanderbilt assessment scales (parent and teacher versions), children global assessment scale, clinical global impression-severity score, clinical global impression-improvement score, and social skills rating system assessed the effectiveness of the treatment. A Likert scale evaluated parents' acceptance of the training modality. Our results showed that the parent training program significantly improved parents' disciplinary practices based on the PRQ-CA, parent ratings of ADHD, oppositional defiant disorder, and conduct disorder symptoms, and the children's global functioning. RESULTS: The treatment effects did not differ between the videoconference and face-to-face groups; however, the videoconference group evidenced statistically greater improvement on the hyperactive symptoms of Vanderbilt assessment scales. Our findings suggest that parent training through a videoconferencing modality may be as effective as face-to-face training and is well accepted by parents. CONCLUSIONS: Parent training via videoconferencing may be an important tool for addressing ADHD in geographic locations that do not have access to appropriate treatment providers.

Imaging manifestations of small cell neuroendocrine carcinoma of the ureter.

Small cell neuroendocrine carcinoma (SCNEC) of the ureter is a rare malignant tumor originating from the metaplasia of urothelial cells. This report presents a case of ureteral SCNEC that was preliminarily disclosed by computed tomography; thereafter, transabdominal ultrasonography, transrectal ultrasonography, and magnetic resonance urography were performed to characterize the mass.

Imaging findings of succinate dehydrogenase-deficient renal cell carcinoma.

Key Clinical Message: A 50-year-old man with a mass located in the left kidney was described by multimodal images, including ultrasonography, computed tomography, and magnetic resonance imaging. After surgical resection of the mass, pathological examination confirmed succinate dehydrogenase-deficient renal cell carcinoma. Abstract: Succinate dehydrogenase-deficient renal cell carcinoma (SDH-deficient RCC) is a malignant tumor in the kidney associated with the loss of mitochondrial enzyme II. Due to its rarity, SDH-deficient RCC is frequently misdiagnosed. We present multimodal imaging and pathologic findings in a 50-year-old male with SDH-deficient RCC.

Imaging findings of superficial angiomyxoma in the eye socket.

Key Clinical Message: A 23-year-old male with a tumor in the eye socket was characterized by multimodal images, including ultrasonography, computed tomography, and magnetic resonance imaging. After admission, surgical resection of the tumor was performed and superficial angiomyxoma was confirmed. Two years later, this tumor recurred in the same location. Abstract: Superficial angiomyxoma (SAM) is a rare benign neoplasm composed mostly of myxoid material that can affect many parts of the body in middle-aged patients. Only a few case reports have involved imaging, which is extremely insufficient. Here, we present a case of SAM in the eye socket evaluated by imaging, including ultrasonography, computed tomography, and magnetic resonance imaging. The patient underwent surgical resection, and the diagnosis of SAM was confirmed. During the postoperative follow-up, the tumor recurred in the same location without metastasis 2 years later.

Mechanisms of Yajieshaba in the treatment of liver fibrosis through the Keap1-Nrf2 signaling pathway.

Yajieshaba (YJSB), a traditional Dai medicine formula containing botanical drugs, is commonly employed in Yunnan due to its significant therapeutic effects on liver protection. Consequently, to determine the efficacy of YJSB and the mechanism of action of Kelch-like ECH-associated protein 1 (Keap1)-nuclear factor erythroid 2-related factor 2 (Nrf2) pathway against liver fibrosis. We wanted to see if YJSB could treat CCl4-induced liver fibrosis by regulating the Keap1-Nrf2 signaling pathway. YJSB significantly improved liver function biochemical indices, liver fibrosis quadruple, hydroxyproline (Hyp), and transforming growth factor-ß1 (TGF-ß1) levels. The staining results demonstrated that the degree of liver fibrosis was significantly reduced. YJSB reduced the content of malondialdehyde (MDA) and elevated the content of superoxide dismutase (SOD) in the liver, exhibiting antioxidant effects; meanwhile, it regulated the expression of Keap1-Nrf2 pathway protein, increased the expression of NAD(P)H: Quinone oxidoreductase (NQO1), Heme Oxygenase 1 (HO-1), Glutamate cysteine ligase modifier subunit (GCLM), and Glutamate cysteine ligase catalytic subunit (GCLC) expression in the liver decreased while Nrf2 expression increased. Fluorescence immunoassay studies demonstrated that YJSB promoted the trans-nuclearization of Nrf2. YJSB possesses anti-liver fibrosis pharmacological effects that improve liver function and effectively counteract CCl4-induced liver fibrosis damage. The mechanism of action might be related to the regulation of protein expression of the Keap1-Nrf2 pathway, increasing the ability of the body to resist oxidative stress and reduce oxidative stress injury.
