Objective Investigate the expression level of discs large homolog associated protein 5(DLGAP5)in oral squamous cell carcinoma(OSCC)and analyze its effects on cell proliferation,migration,invasion capacity,and the Warburg effect.Methods Bioinformatics analysis was performed to identify the potential therapeutic targets for OSCC.A total of 72 OSCC tissue samples and 40 adjacent non-cancerous tissue samples collected in the First Affiliated Hospital of Shihezi University from 2013 to 2024 were included,and the clinical pathological and prognostic data were collected from patients.Immunohistochemistry assay was applied to detect the protein expression of DLGAP5,and its association with clinical pathological features was analyzed.Kaplan-Meier survival curve was plotted for survival analysis,and Cox regression model was employed to analyze the prognostic factors.The expression of DLGAP5 at mRNA and protein levels was detected in HOK,SCC-9,SCC-15,SCC-25,and CAL-27 cell lines with RT-qPCR and Western blotting,respectively.Four small interfering RNAs(siRNAs)were designed to target the DLGAP5 sequence,and then based on the transfection efficiency,the sequence with optimal silencing effect was selected for subsequent functional studies.After DLGAP5 was silenced in the CAL-27 and SCC-15 cells,Western blotting was applied to detect the expression of hexokinase 2(HK2)and enolase 1(ENO1),CCK-8,scratch healing and Transwell assays were conducted to assess cell proliferation,migration,and invasion capabilities,and glucose,lactate,and ATP detection kits were utilized to determine the glycolytic metabolic levels in OSCC cells.Results Bioinformatics analysis indicates that DLGAP5 is a potential key therapeutic target for OSCC.Experimental validation demonstrated that DLGAP5 was highly expressed in both OSCC tissues and cells(P<0.05).Analysis of clinical pathology and prognostic data revealed that DLGAP5 expression level was significantly correlated with tumor TNM stage,lymph node metastasis,and differentiation grade in OSCC patients,and high DLGAP5 expression was associated with poor prognosis(P<0.05).DLGAP5 silencing resulted in significantly reduced expression of HK2 and ENO1,markedly decreased levels of glycolytic metabolites(P<0.05),and notably declined cell proliferation,migration,and invasion capabilities(P<0.05).Conclusion DLGAP5 is highly expressed in OSCC.Silencing DLGAP5 may inhibit OSCC cell proliferation,migration,and invasion by indirectly regulating the Warburg effect,and the molecule is associated with poor prognosis in the OSCC patients.

OBJECTIVE To evaluate the clinical efficacy of modified Zhujing Pills in the treatment of dry age-related macular degeneration(AMD)of liver and kidney insufficiency type.METHODS 64 patients with dry AMD of liver and kidney insufficiency type were randomly divided into an experimental group and a control group,32 patients each.The control group was given oral treat-ment with Laishiding capsules,and the experimental group was given oral treatment with modified Zhujing Pills granules.The treatment course for both groups was 3 months.Before and after treatment,the patients in the two groups were observed for TCM syndrome scores,visual acuity,fundus autofluorescence(AF),changes in drusen area within 5 mm of the fovea,and plasma superoxide dis-mutase(SOD),glutathione peroxidase(GSH-Px)activity and malondialdehyde(MDA)levels.RESULTS After treatment,the scores of TCM syndromes in the experimental group were significantly reduced(P＜0.05,P＜0.01),and the efficacy of TCM syn-dromes was better than that of the control group(P＜0.01);the visual acuity of the patients in the experimental group was significantly improved,AF was significantly weakened and the area of drusen was reduced(P＜0.05,P＜0.01),which were better than those in the control group(P＜0.05);the plasma SOD and GSH-Px activities of the experimental group were increased,and the MDA level was significantly lowered(P＜0.05,P＜0.01),which were better than the control group(P＜0.05).CONCLUSION Modified Zhujing Pills can reduce fundus AF intensity,decrease macular drusen area,improve visual acuity,and reduce TCM syndrome scores in pa-tients with dry AMD.The therapeutic mechanism may be related to its antioxidant effect.

Cerebral amyloid angiopathy (CAA) is a cerebral small vascular disease caused by pathological deposition of β-amyloid protein in cortical and pial arteries and capillaries. It is the main cause of non-traumatic cerebral lobular hemorrhage and has a high risk of recurrent hemorrhage. Studies have shown that specific imaging markers, such as cerebral microbleeds, cortical superficial siderosis, convexal subarachnoid hemorrhage, centrum semiovale-perivascular spaces and the overall burden of cerebral small vascular disease, may be more effective in predicting the risk of bleeding recurrence in patients with CAA. This article reviews the imaging markers used to predict the risk of recurrent bleeding in patients with CAA, in order to provide a new direction for the establishment of a risk assessment system for recurrent bleeding.

OBJECTIVETo detect the expression of transient receptor potential canonical 1 (TRPC1) in a mouse model of ozone-induced lung inflammation and explore its role in lung inflammation.

METHODSIn a mouse model of lung inflammation established by ozone exposure, the expression of TRPC1 in the inflammatory lung tissues was detected by RT-PCR, Wstern blotting and immunohistochemistry.

RESULTSCompared to the control mice, the mice exposed to ozone showed significantly increased expression level of TRPC1 mRNA and protein in the inflammatory lung tissues (P<0.05). Immunohistochemistry showed increased TRPC1 protein expressions in the alveolar epithelial cells, bronchial epithelial cells, and inflammatory cells in the inflammatory lung tissues (P<0.05). The mRNA and protein expression levels of TRPC1 were positively correlated with the counts of white blood cells, macrophages, neutrophils and lymphocytes in the bronchoalveolar lavage fluid of the exposed mice (P<0.01).

CONCLUSIONTRPC1 may play a role in ozone-induced lung inflammation in mice.
