Tertiary lymphoid structure(TLS)is ectopic lymphoid-like organs induced under pathological conditions such as chronic inflammation and tumor microenvironment,which exhibits functional characteristics similar to secondary lymphoid or-gans and is commonly observed in various cancers.This review focuses on the biological characteristics of TLS in oral squamous cell carcinoma(OSCC),summarizing their components,formation mechanisms,and maturation stages within the tumor microen-vironment.It systematically analyzes the interrelationships between TLS features,including maturation levels,spatial distribu-tion,and cellular composition,and the progression and prognosis of OSCC.The review highlights the bidirectional interactions between TLS and microbial colonization in OSCC,as well as the impact of TLS on the efficacy of radiotherapy and chemotherapy and their potential predictive value for treatment responses.

Objective To explore the relationship between the inhibitory effect of quercetin on AC16 cardiomyocyte proliferation and the Wnt/β-catenin signaling pathway,the relationship between quercetin(quercetin,QCT)and the proliferation of AC16 cardiomyocytes through in vitro was investigated.Methods AC16 cells were stimulated with different concentrations of QCT.The effects of QCT on AC16 cell proliferation were detected by inverted microscope photography,trypan blue counting,and CCK-8 assay.Western blot was used to detect the effects of QCT on the expression of phosphorylated β-catenin(p-β-catenin),c-Myc,β-catenin,low density lipoprotein receptor-related protein 5(LRP5),and LRP6.The effect of quercetin on cell proliferation was detected after overexpressing β-catenin ΔN,LRP5,and LRP6 genes,and after silencing LRP5 and LRP6 genes by trypan blue counting.Results Compared with the control group,QCT could decrease the number of AC16 cells and inhibit the proliferation rate,which was concentration-dependent.At the protein expression level,10 and 20 μmol/L QCT led to an significant upregulated modification of p-β-catenin protein(P<0.05)and significant downregulation of c-Myc,β-catenin,LRP5,and LRP6 protein expression(P<0.05)in AC16 cells.Therefore,10 μmol/L QCT was chosen as the intervention concentration.Overexpression of β-catenin ΔN,LRP5,and LRP6 genes in AC16 cells significantly rescued the cell proliferation inhibition caused by 10 μmol/L QCT compared to the drug-only group(P<0.05).Conversely,silencing LRP5 and LRP6 genes led to inhibition of AC16 cell proliferation,and the combination with 10 μmol/L QCT did not exacerbate the inhibition(P>0.05).Conclusion The quercetin could inhibit the Wnt/β-catenin signaling pathway via significant downregulation of LRP5/6,thereby attenuate cell proliferation of AC16 cardiomyocytes.

OBJECTIVE To analyze the clinical characteristics of Stevens-Johnson syndrome （SJS） and toxic epidermal necrolysis （TEN） induced by tislelizumab， providing evidence for clinical medication safety. METHODS Case reports of tislelizumab-related SJS/TEN were retrieved from CNKI， VIP， Wanfang Data， PubMed， ScienceDirect， and Embase. Descriptive analysis was performed. RESULTS Seventeen cases from 17 publications were included （SJS 4 cases， TEN 13 cases）. Among them， there were 10 males and 7 females. Twelve patients were aged between 70 and 79 years. The predominant tumor type was lung cancer （10 cases）. Thirteen patients received combination therapy with chemotherapeutic drugs. The median onset time of SJS/ TEN was 26 （4， 104） days. Nine patients developed SJS/TEN after the first administration of the drug. Sixteen patients exhibited prodromal rash symptoms， primarily characterized by severe skin damage such as skin detachment， accompanied by mucosal injury. Sixteen patients improved after symptomatic treatment， while one patient died. CONCLUSIONS Tislelizumab-associated SJS/TEN risk is higher in elderly patients， males， those with lung cancer and those receiving combination chemotherapy. Mucosal lesions and atypical rashes may indicate the early onset of SJS/TEN. During clinical use， pharmaceutical care can be carried out through measures such as identifying high-risk populations， closely monitoring skin symptoms from the first administration to the fifth treatment cycle， and enhancing patient education. When relevant symptoms occur， the medication should be promptly discontinued and symptomatic treatment should be administered to ensure the patient’s medication safety.

Objective:To evaluate the clinical effect of temporomandibular joint disc anchoring and deviated jaw splint in the treatment of adolescent patients with mandibular deviation deformity complicated with anterior disc displacement of temporomandibular joint.Methods:A total of 30 patients with mandibular deviation deformity complicated with anterior disc displacement of temporomandibular joint who were treated in the Suzhou Municipal Hospital from January 2020 to March 2023 were prospectively selected. Among them, 10 patients in the surgical splint group received temporomandibular joint disc anchoring combined with sequential treatment of deviated jaw splint; 20 patients in the splint group received deviated jaw splint treatment. The improvement of facial deviation before and after treatment was compared between the two groups, and magnetic resonance imaging (MRI) was used to evaluate the stability of temporomandibular joint disc position and the change of condylar height.Results:After treatment, the midfacial line deviation was (1.3±0.3)mm and the condylar height was (21.5±0.6)mm in the surgical splint group; in the splint group, the midfacial line deviation was (1.5±0.4)mm and the condylar height was (21.6±0.7)mm. Both facial deviation and condylar height in the two groups were significantly improved compared with those before treatment (all P<0.01). During the treatment course, MRI was taken every 3 months in both groups. The stability rate of the joint disc in the surgical splint group was 100%(10/10), and that in the splint group was 90.0%(18/20). Conclusions:The application of temporomandibular joint disc anchoring combined with sequential treatment of deviated jaw splint in adolescent patients with mandibular deviation deformity complicated with anterior disc displacement of temporomandibular joint can achieve good clinical effects. The position of the temporomandibular joint disc remains stable before and after treatment, and new bone formation occurs in the condyle.

Objective To explore the efficacy of"internet+"family doctor contract service model on controlling risk factors related to atherosclerotic cardiovascular disease(ASCVD)such as hypertension,dyslipidemia,and diabetes in young and middle-aged patients in the community.Methods A total of 231 young and middle-aged patients with ASCVD who were contracted and treated regularly in Shanghai Yangpu District Xinjiangwancheng Community Health Service Center from Jan to Dec 2020.According to the different intervention models,they were divided into the traditional group receiving the conventional family doctor contract service and the Internet group taking"internet+"family doctor contract service mode for intervention.The systolic blood pressure,diastolic blood pressure,fasting plasma glucose(FPG),low density lipoprotein(LDL-C),triglyceride(TG)and total cholesterol(TC)were compared within and between the two groups before intervention,three months after intervention,and one year after intervention,to evaluate the control effects of the two intervention modes.Results The 231 patients,of which 113 cases in traditional group and 118 cases in Internet group,were recruited in the study.there were no significant differences in gender,age and proportions of hypertension,diabetes and dyslipidemia between the two groups.Before intervention,there were no significant differences in systolic blood pressure,diastolic blood pressure,FPG,LDL-C,TG and TC between the two groups.Three months after intervention,the systolic blood pressure,diastolic blood pressure,FPG,LDL-C,TG and TC of the two groups were significantly lower than those before the intervention(all P<0.05),and the systolic blood pressure and diastolic blood pressure of the Internet group were significantly lower than those of the traditional group(all P<0.05),but there was no significant difference between the two groups in FPG,LDL-C,TG and TC.One year after the intervention,the systolic blood pressure,diastolic blood pressure,FPG,LDL-C,TG and TC of the patients in the two groups decreased significantly compared with those before intervention(all P<0.05),while the Internet group decreased more significantly(all P<0.05).Conclusion Compared with the traditional contract model,"internet+"family doctor contract service had better management effect on ASCVD-related risk factors in young and middle-aged patients in the community,and benefits the patients to a higher degree.

OBJECTIVE: To explore the functional roles and underlying mechanisms of neferine in the context of angiotensin II (Ang II)-induced hypertension and vascular dysfunction. METHODS: Male mice were infused with Ang II to induce hypertension and randomly divided into treatment groups receiving neferine or a control vehicle based on baseline blood pressure using a random number table method. The hypertensive mouse model was constructed by infusing Ang II via a micro-osmotic pump (500 ng/kg per minute), and neferine (0.1, 1, or 10 mg/kg), valsartan (10 mg/kg), or double distilled water was administered intragastrically once daily for 6 weeks. A non-invasive blood pressure system, ultrasound, and hematoxylin and eosin staining were performed to assess blood pressure and vascular changes. RNA sequencing and network pharmacology were employed to identify differentially expressed transcripts (DETs) and pathways. Vascular ring tension assay was used to test vascular function. A7R5 cells were incubated with neferine for 24 h and then treated with Ang II to record the real-time Ca²⁺ concentration by confocal microscope. Immunohistochemistry (IHC) and Western blot were used to evaluate vasorelaxation, calcium, and the extracellular signal-regulated kinase (ERK)1/2 pathway. RESULTS: Neferine treatment effectively mitigated the elevation in blood pressure, pulse wave velocity, aortic thickening in the abdominal aorta of Ang II-infused mice (P<0.05). RNA sequencing and network pharmacology analysis identified 355 DETs that were significantly reversed by neferine treatment, along with 25 potential target genes, which were further enriched in multiple pathways and biological processes, such as ERK1 and ERK2 cascade regulation, calcium pathway, and vascular smooth muscle contraction. Further investigation revealed that neferine treatment enhanced vasorelaxation and reduced Ca²⁺-dependent contraction of abdominal aortic rings, independent of endothelium function (P<0.05). The underlying mechanisms were mediated, at least in part, via suppression of receptor-operated channels, store-operated channels, or voltage-operated calcium channels. Neferine pre-treatment demonstrated a reduction in intracellular Ca²⁺ release in Ang II stimulated A7R5 cells. IHC staining and Western blot confirmed that neferine treatment effectively attenuated the upregulation of p-ERK1/2 both in vivo and in vitro, which was similar with treatment of ERK1/2 inhibitor PD98059 (P<0.05). CONCLUSIONS Neferine remarkably alleviates Ang II-induced elevation of blood pressure, vascular dysfunction, and pathological changes in the abdominal aorta. This beneficial effect is mediated by the modulation of multiple pathways, including calcium and ERK1/2 pathways.

BACKGROUND: Chronic kidney disease (CKD) is associated with common pathophysiological processes, such as inflammation and fibrosis, in both the heart and the kidney. However, the underlying molecular mechanisms that drive these processes are not yet fully understood. Therefore, this study focused on the molecular mechanism of heart and kidney injury in CKD. METHODS: We generated an microRNA (miR)-26a knockout (KO) mouse model to investigate the role of miR-26a in angiotensin (Ang)-II-induced cardiac and renal injury. We performed Ang-II modeling in wild type (WT) mice and miR-26a KO mice, with six mice in each group. In addition, Ang-II-treated AC16 cells and HK2 cells were used as in vitro models of cardiac and renal injury in the context of CKD. Histological staining, immunohistochemistry, quantitative real-time polymerase chain reaction (PCR), and Western blotting were applied to study the regulation of miR-26a on Ang-II-induced cardiac and renal injury. Immunofluorescence reporter assays were used to detect downstream genes of miR-26a, and immunoprecipitation was employed to identify the interacting protein of LIM and senescent cell antigen-like domain 1 (LIMS1). We also used an adeno-associated virus (AAV) to supplement LIMS1 and explored the specific regulatory mechanism of miR-26a on Ang-II-induced cardiac and renal injury. Dunnett's multiple comparison and t -test were used to analyze the data. RESULTS: Compared with the control mice, miR-26a expression was significantly downregulated in both the kidney and the heart after Ang-II infusion. Our study identified LIMS1 as a novel target gene of miR-26a in both heart and kidney tissues. Downregulation of miR-26a activated the LIMS1/integrin-linked kinase (ILK) signaling pathway in the heart and kidney, which represents a common molecular mechanism underlying inflammation and fibrosis in heart and kidney tissues during CKD. Furthermore, knockout of miR-26a worsened inflammation and fibrosis in the heart and kidney by inhibiting the LIMS1/ILK signaling pathway; on the contrary, supplementation with exogenous miR-26a reversed all these changes. CONCLUSIONS Our findings suggest that miR-26a could be a promising therapeutic target for the treatment of cardiorenal injury in CKD. This is attributed to its ability to regulate the LIMS1/ILK signaling pathway, which represents a common molecular mechanism in both heart and kidney tissues.
