OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets， followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established ， and the zebrafish were treated with L. ruthenicum Murr. extract （LRME） at concentrations of 0.1， 0.2 and 0.4 mg/mL， respectively； 24 h later， behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 （IL-6）， IL-1β， IL-10， tumor necrosis factor-α （TNF-α）]， oxidative stress markers [superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， catalase （CAT）]， and neurotransmitters [5- hydroxytryptamine （5-HT）， γ-aminobutyric acid （GABA）， glutamic acid （Glu）， dopamine （DA）， and norepinephrine （NE）] were measured. The protein expression levels of protein kinase B1 （AKT1）， phosphorylated AKT1 （p-AKT1）， epidermal growth factor receptor （EGFR）， B-cell lymphoma 2 （Bcl-2）， sarcoma proto-oncogene，non-receptor tyrosine kinase （SRC）， and heat shock protein 90α family class A member 1 （HSP90AA1） in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these， apigenin， naringenin and others were recognized as core active compounds， while AKT1， EGFR and others served as key targets； EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-， medium-， and high-dose groups were 54.60%， 69.03% and 77.97%， 开发。E-mail：hjp_yft@163.com respectively， while the inhibition ratios of locomotor distance were 0.57， 0.83 and 0.95， respectively. Compared with the model group， the number of resting counts， resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups （P＜0.05）. Neuronal damage in the brain was alleviated. Additionally， the levels of IL-6， IL-1β， TNF-α， MDA， Glu， DA and NE， as well as the protein expression levels of AKT1， p-AKT1， EGFR， SRC and HSP90AA1， were markedly reduced （P＜0.05）， while the levels of IL-10， SOD， GSH-Px， CAT， 5-HT and GABA， as well as Bcl-2 protein expression， were significantly elevated （P＜0.05）. CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects， and its specific mechanism may be related to the regulation of inflammatory responses， oxidative stress， neurotransmitter balance， and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

Objective:To investigate the function and mechanism of exosome Linc00665 in modulating CD8+T cell immunoreactivity to promote radiotherapy resistance in OSCC.Methods:HOEC,SCC9 and SCC9-RR exosomes were extracted and identified,and the expression of Linc00665 was detected by qRT-PCR in cell lines and exosomes.The expression of TNF-α,IFN-γ,perforin and granzyme B in each treatment group was detected by ELISA(PBS,SCC9 exo,SCC9-RR exo).The killing ability of CD8+T cells against SCC9 cells in each treatment group was detected by CCK-8 assay.The targets of Linc00665 were further bioinformatically ana-lyzed and verified by qRT-PCR and Western blot.The expression of Linc00665,miR-28-5p and PD-1 in CD8+T cells was exogenous-ly regulated,the expression of immunoreactive factors in the supernatants of each treatment group was detected by ELISA(NC,sh-Linc00665,miR-28-5p inhibitor,sh-PD-1),and the killing ability of cells in each group was detected by CCK-8 method.Results:The concentrations of TNF-α,IFN-γ,perforin and granzyme B in the supernatants of cell culture in the SCC9-RR exo/CD8+T group were significantly decreased compared with those in the PBS/CD8+T group and the SCC9 exo/CD8+T group(P＜0.05),and the kill-ing ability of the cells in the SCC9-RR exo group was significantly decreased compared with those in the PBS group and the SCC9 exo group(P＜0.05),suggesting that SCC9-RR exo could inhibit the tumor killing ability of CD8+T cells.qRT-PCR results suggested that Linc00665 was highly expressed in the SCC9-RR cell line as well as exosome(P＜0.05).It was further verified by bioinformat-ics analysis that Linc00665 could regulate PD-1 expression via miR-28-5p,thereby modulating CD8+T cell immunoreactivity to pro-mote OSCC radiotherapy resistance.Conclusion:Exosome Linc00665 regulates CD8+T cell immunoreactivity through miR-28-5p/PD-1 axis to promote OSCC radiotherapy resistance.

Objective To investigate whether curcumin(CUR)can reduce chondrocyte inflammation and cartilage degradation in osteo-arthritis(OA)and the underlying mechanisms.Methods A rat model of OA was established.Rats were randomly divided into a Sham,OA,CUR+OA,and deferoxamine(DFO)+OA groups with 10 mice in each group.Chondrocytes from 5-day-old SD rats were divided into the control,interleukin-1β(IL-1β),CUR+IL-1β,and DFO+IL-1β groups.A CCK-8 assay was performed to assess the effects of CUR on cell viability alone or combined with IL-1β.Toluidine blue staining and alcian blue staining were used to observe the morphological changes of IL-1β-induced chondrocytes.The expression of inflammatory response-related proteins(COX-2 and iNOS),extracellular matrix degradation-related proteins(COL2A and MMP13),and p53,SLC7A11,and GPX4 proteins during ferroptosis were detected by Western blotting.The mitochondrial membrane potential was detected by JC-1 staining.Mitochondrial morphology was observed using transmission electron microscopy.Safranine O-fast green/HE staining was performed on cartilage tissues.Immunohistochemical staining was performed to detect COL2A and SLC7A11 expression levels.Results CUR and DFO were found to reduce IL-1β-induced inflammation,cartilage degradation,and ferroptosis,and restore mitochondrial function in chondrocytes.CUR also reversed IL-1β-induced changes in collagen Ⅱ,p53,SLC7A11,GPX4,MMP13,iNOS,and COX-2 levels.In vivo,intra-articular injection of CUR significantly improved cartilage injury in the OA rat model,and the percentages of COL2A-and SLC7A11-positive cells significantly increased in the CUR+OA and DFO+OA groups.Conclusion CUR inhibits ferroptosis and ameliorates cartilage degeneration in OA through p53 signaling pathway.

Early neurological deterioration(END)occurs in patients with acute cerebral infarction after recombinant tissue-plasminogen activator(rt-PA)intravenous thrombolysis,which seriously affects the prognosis of patients and even causes death.However,there is no effective treatment.This report describes two patients with acute ischemic stroke presenting with right-sided limb weakness within 4.5 hours of onset.Brain CT ruled out cerebral hemorrhage and both patients were diagnosed with acute ischemic stroke.END occurred within 24 hours after intravenous thrombolysis with rt-PA.Reexamine Brain CT showed no evidence of cerebral hemorrhage.The patients were treated with continuous tirofiban infusion for 48 hours,overlapping with oral antiplatelet therapy for 4 hours and 6 hours,respectively.After discontinuation of tirofiban,no further neurological deterioration was observed.At the 3-month follow-up,there was no recurrence,and the modified Rankin scale(mRS)scores were 1 and 3,respectively.This study delineates the diagnostic and therapeutic trajectories of two paradigmatic cases to inform clinical decision-making for analogous presentations,thereby contributing to evidence-based management strategies.

Objective:To compare the effectiveness of a new virtual reality (VR) working memory test system with that of the traditional E-prime working memory test system in terms of evaluating executive function in cognitive rehabilitation.Methods:Two experienced rehabilitation therapists tested 30 healthy subjects. The average reaction time and accuracy of the traditional and the VR-based working memory test systems in completing the 2-back task were compared. The usability and user experience of the VR-based working memory test system were also evaluated using the system usability scale (SUS), a simulator discomfort scale (SSQ) and semi-structured interviews.Results:There was no significant difference in the average reaction time and accuracy of the 30 subjects between the two different tests. The SUS score of the VR working memory test was at the " Good-Excellent" level, and the SSQ scores demonstrated that no significant discomfort was observed. In the interviews the VR working memory test system was described as easy to operate and as having a strong sense of immersion.Conclusions:The VR-based working memory test system has good usability and user acceptance, and can provide subjects with an immersive and persona-lized test scenario. Therefore, it can be used as a tool for testing working memory.

Chest CT pulmonary angiography (CTPA) has certain auxiliary diagnostic value for the clinical diagnosis of invasive pulmonary aspergillosis (IPA) . Three patients with hematological malignancies were reported, including 2 ones after allogeneic hematopoietic stem cell transplantation and 1 ones after chemotherapy for refractory recurrent leukemia. Each patient was treated with antibiotics for at least 48 hours after the onset of fever, they all underwent chest high-resolution CT (HRCT) scans without fever resolution. CT revealed at least one dense pulmonary consolidation shadow with a diameter greater than 10 mm, and subsequently a CTPA examination was performed to observe the effect of CTPA imaging signs for the diagnosis of IPA. There were 2 patients with positive vascular occlusion sign (VOS) and 1 patient with negative VOS detected by CTPA. Among them, 2 patients with positive VOS were diagnosed with possible IPA and received with diagnosis-driven antifungal treatment, which improved their conditions. One patient with negative VOS sign was diagnosed with diffuse large B-cell lymphoma involving the lungs. After receiving anti-lymphoma treatment, the lesions significantly reduced in size. The vascular occlusion sign detected by CTPA is relatively characteristic. For high-risk IPA patients, it helps to improve the specificity of imaging diagnosis and guide clinical treatment decisions.
