Background: High-mobility group box protein 1 (HMGB1) is a chromatin-binding protein involved in arthritis, ischemia, sepsis, atherosclerosis, neurodegenerative disorders, meningitis, and cancer. HMGB1 exhibits dual roles in cancer, acting as either a tumor suppressor or oncoprotein depending on context. Objective: This research aimed to elucidate HMGB1’s functional significance in cutaneous squamous cell carcinoma (cSCC). Methods: We overexpressed HMGB1 in cSCC cell lines using recombinant adenovirus and examined its effects on cell proliferation, colony formation, and cell migration. Results: Immunohistochemical analysis revealed elevated HMGB1 expression levels in cSCC tissue relative to normal epidermis. To assess the influence of HMGB1, we employed recombinant adenoviruses expressing HMGB1 to transduce SCC cell lines (SCC12 and SCC13). Enhanced HMGB1 expression significantly promoted cellular proliferation and colony formation capacity.Notably, HMGB1 overexpression elevated the levels of proliferation regulators, including P63, SOX2, CDK4 and CDK6. Furthermore, HMGB1 overexpression substantially enhanced tumor invasiveness, accompanied by upregulation of epithelial-mesenchymal transition (EMT) biomarkers. Mechanistically, overexpression of HMGB1 enhanced transforming growth factor-β signaling by increasing phosphorylation of SMAD2/3, the key mediators of EMT. Conclusion These data imply that HMGB1 acts as a tumor-promoting factor in cSCC.

Objective: To investigate the distribution of IgM anti-A/B titers among group O whole blood donors in Jiangsu, establish a low-titer threshold, and analyze the demographic characteristics of low-titer donors, so as to provide data for recruiting low-titer group O whole blood (LTOWB) donors. Methods: Plasma samples from 1 009 group O whole blood donors were tested for IgM anti-A and anti-B titers using the microplate technique. The distribution of antibody titers was analyzed to establish a low-titer threshold. The distribution trends of titers across different demographic groups were also analyzed. Results: The peak titer for anti-A, anti-B were 64 (31.5%), 4 (23.8%), respectively, The proportion of donors with both anti-A and anti-B titers below 64 was 97.3% (982/1 009). The mean anti-A titer was higher than anti-B titer. Anti-A titers were higher in female donors than in male donors (P<0.05). The anti-A titers differed significantly among different age groups (P<0.05). However, no significant difference in titers was observed based on the number of donations (P>0.05). Conclusion: A titer of 64 can be used as the reference threshold of LTOWB in Jiangsu. Male donors of appropriate age are more suitable than female donors for establishing an emergency panel of LTOWB mobile donors.

The ventral anterior (VA) nucleus of the thalamus is a major target of the basal ganglia and is closely associated with the pathogenesis of Parkinson's disease (PD). Notably, the VA receives direct innervation from the hypothalamic histaminergic system. However, its role in PD remains unknown. Here, we assessed the contribution of histamine to VA neuronal activity and PD motor deficits. Functional magnetic resonance imaging showed reduced VA activity in PD patients. Optogenetic activation of VA neurons or histaminergic afferents significantly alleviated motor deficits in 6-OHDA-induced PD rats. Furthermore, histamine excited VA neurons via H1 and H2 receptors and their coupled hyperpolarization-activated cyclic nucleotide-gated channels, inward-rectifier K⁺ channels, or Ca²⁺-activated K⁺ channels. These results demonstrate that histaminergic afferents actively compensate for Parkinsonian motor deficits by biasing VA activity. These findings suggest that targeting VA histamine receptors and downstream ion channels may be a potential therapeutic strategy for PD motor dysfunction.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Aim To study the renal protective effect of balanophora polysaccharide(BPS)on diabetic nephrop-athy(DN)mice and explore the related mechanisms.Methods A DN mouse model was induced using a high-fat diet combined with intraperitoneal injection of streptozotocin(STZ),which was indicated by fasting blood glucose higher than 11.1 mmol·L-1,accompa-nied by diabetic symptoms such as polydipsia,polydia-gia,polyuria and weight loss,then BPS intervention was performed.Body weight and fasting blood glucose of each group mice were detected;automatic biochemical analyzer was used to detect blood creatinine(SCr),blood urea nitrogen(BUN),24 h urinary protein(24 h UP),triglycerides(TG),total cholesterol(TC),alanine aminotransferase(ALT)content;ELISA was applied to determine serum inflammatory factor interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)level;HE and Masson staining were employed to observe renal his-topathological morphology;Western blot was used to de-tect Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MyD88),nuclear factor κB(NF-κB)for pro-tein expression.Results Compared with the model group,after BPS,body weight and fasting blood glucose decreased(P＜0.01 or P＜0.05);SCr,BUN,24 h UP,TC,TG and ALT significantly decreased(P＜0.01 or P＜0.05);the levels of the proinflammatory factors TNF-α and IL-6 were significantly reduced(P＜0.01 or P＜0.05);renal tissue injury and fibrosis decreased;TLR4,MyD88,NF-κB protein expression significantly decreased(P＜0.01 or P＜0.05).Conclusion BPS has a protective effect on the kidneys of DN mice,re-ducing the blood glucose level,improving liver and kid-ney function,alleviating renal tissue damage and renal fibrosis,and reducing inflammation response.Its mecha-nism may be related to the regulation of TLR4/MyD88/NF-κB signaling pathway.

BACKGROUND:Synovitis is involved in all stages of osteoarthritis and is a key factor contributing to the development of osteoarthritis.Studies have shown that circular RNA(circRNA)plays an important role in the proliferation,apoptosis and extracellular matrix degradation of synovial cells and chondrocytes.OBJECTIVE:To observe the effects of circRNA SEC24A on the interleukin-1β-induced proliferation,apoptosis,and expression of inflammatory factors in human synovial fibroblasts.METHODS:Human synovial fibroblasts were divided into four groups,including control group,interleukin-1β group,empty vector group,and sh-circSEC24A group.Except for the control group,the other three groups were induced with 10 ng/mL interleukin-1β for 24 hours to establish inflammatory cell models;the empty vector group and sh-circSEC24A group were infected with empty vector virus and lentiviral vector knocking down circSEC24A.CCK-8 assay was used to detect cell proliferation.Flow cytometry was used to detect cell apoptosis.ELISA was used to detect the levels of matrix metalloproteinase-9,matrix metalloproteinase-13,interleukin-6,and tumor necrosis factor-α in cell supernatant.Western blot assay was used to detect the relative expression levels of Bax,Bcl-2,matrix metalloproteinase-9,matrix metalloproteinase-13,casepase3,cleaved-casepase3,casepase8,and cleaved-casepase8 proteins in cells.RESULTS AND CONCLUSION:(1)qRT-PCR results showed that compared with the normal group,the expression of circSEC24A in human synovial fibroblasts induced by interleukin 1β was significantly up-regulated.(2)The absorbance value of cells in the sh-circSEC24A group detected by CCK-8 assay was significantly higher than that of interleukin 1β group and empty vector group(P＜0.05).The apoptosis rate of sh-circSEC24A group detected by flow cytometry was significantly lower than that of interleukin 1β group and empty vector group(P＜0.05).(3)The levels of tumor necrosis factor α and interleukin 6 in the supernatant of human synovial fibroblasts in the sh-circSEC24A group detected by ELISA were significantly lower than those in the interleukin 1β group and the empty vector group(P＜0.01,P＜0.001).(4)Western blot assay results showed that compared with the interleukin 1β group and the empty vector group,the expression of the pro-apoptotic factor Bax protein in the sh-circSEC24A group significantly decreased,and the expression of the anti-apoptotic factor Bcl-2 protein increased significantly(P＜0.05);apoptosis and related activating factors cleaved-casepase3 and cleaved-casepase8 protein expressions were both reduced(P＜0.05).(5)ELISA and western blot assay results showed that compared with the interleukin 1β group and the empty vector group,the sh-circSEC24A group had lower levels of matrix metalloproteinase 9 and matrix metalloproteinase 13 protein(P＜0.05).These findings indicated that the expression of circSEC24A was abnormally increased in human synovial fibroblasts induced by interleukin 1β.Knocking down circSEC24A expression could promote the proliferation of human synovial fibroblasts and inhibit apoptosis,inflammatory factor release,and extracellular matrix degradation,suggesting that circSEC24A may be an important intervention target for early osteoarthritis.

Objective:To analyze the factors associated with long-term survival after radical resection of hepatitis B virus(HBV)-associated hepatocellular carcinoma(HCC),and to construct random forest and Cox regression models,to evaluate the two models.Methods:A total of 368 patients with HBV-infected HCC who underwent radical resection were selected retrospectively.These patients were categorized as having a good prognosis(n=266)or a poor prognosis(n=102)based on their survival and mortality status.Univariate and Cox regression analysis were used to identify fac-tors that predict poor prognosis in HCC patients after surgery,and Cox regression and random forest prediction models were constructed and evaluated.Results:There were significant differences in smoking history,Child-Pugh classifica-tion,cirrhosis,microvascular invasion,TNM staging,tumor capsule integrity,platelet-to-lymphocyte ratio(PLR),regular antiviral therapy,HBV-DNA load,alpha-fetoprotein(AFP),neutrophil-to-lymphocyte ratio(NLR),systemic immune in-flammatory index(SII),and albumin-to-globulin ratio(AGR)between the two groups(P<0.05);Cox regression showed that cirrhosis,microvascular invasion,regular antiviral treatment,HBV-DNA load,NLR,PLR,SII,and AGR were related factors that negatively affected the prognosis of patients with HBV-infected HCC after surgery(P<0.05),with an AUC of 0.870 for predicting prognosis;the importance ranking obtained by the random forest model was HBV-DNA load,cirrho-sis,regular antiviral therapy,microvascular invasion,NLR,PLR,AGR,and SII,with an AUC of 0.926 for predicting prog-nosis;the AUC predicted by the random forest model was greater than that predicted by the Cox regression model(Z=2.411,P=0.016).Conclusion:HBV-DNA load,cirrhosis,regular antiviral therapy,microvascular invasion,NLR,PLR,AGR,and SII are factors that affect the poor prognosis of patients with HBV-related HCC after surgery.The random for-est prediction model constructed based on these factors has high predictive value and is superior to the Cox regression prediction model.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.
