OBJECTIVE: To evaluate the efficacy and safety of denosumab in the treatment of prostate cancer with bone metastases. METHODS: Relevant studies were retrieved from PubMed, EMBASE, Cochrane, Web of Science, Sinomed , CNKI and Wanfang databases. The Cochrane risk-of-bias assessment tool was used to evaluate the quality of included studies, and relevant data were extracted. meta-analysis was performed using RevMan 5.4 and RStudio software, and forest plots were generated. RESULTS: Six randomized controlled trials (RCTs) were included. Compared with the control group, denosumab significantly reduced the risk of skeletal-related events (HR=0.78, 95% CI: 0.62-0.93). In terms of safety, denosumab did not increase the risk of total adverse events, severe adverse events and the adverse events higher than CTC grade 3. CONCLUSION Denosumab can delay the time to first skeletal-related event with good safety. However, due to the limitations of this study, further high-quality, large-sample, multicenter RCTs are needed to confirm these findings.

Objective:To analyze the epidemiological and etiological characteristics of a death case of meningococcal meningitis in Hengyang city, Hunan Province in 2024.Methods:Epidemiological investigation of the death case was performed, and samples from the patient and close contacts were collected. Following cultivation and isolation, Neisseria meningitidis ( Nm) strains were analyzed by antimicrobial susceptibility testing, pulsed field gel electrophoresis (PFGE), and whole-genome sequencing for analyzing epidemiological and etiological characteristics. Phylogenetic analysis was carried out using core genomic multilocus sequence typing (cgMLST). Results:The case was a 16-year-old high school boarding student with fulminant meningococcal meningitis. He had shock symptoms, and died within 24 h of the onset of symptoms. Six Nm strains were isolated from the patient and his roommates, belonging to two distinct clades. Isolate 144569 from the patient was highly homologous to isolate 144572 from a close contact, both belonging to the highly pathogenic sublineage L44.1 of CC4821. The typical molecular features was C: P1.7-2, 14: F5-101: ST4821 (CC4821). The two strains carried the antimicrobial resistance genes of gyrA-71 and penA-552, indicating reduced susceptibility to quinolone and penicillin, which was with their resistance phenotype. The isolates from four close contacts clustered within the same clade, characterized by the molecular features of B: P1.18-25, 9-18: ST5829 (UA). Conclusions:The death case is caused by Nm serogroup C from highly pathogenic sublineage L44.1 of CC4821. The spread of this isolate has the potential risk of outbreaks of invasive meningococcal disease. It is necessary to enhanced the molecular epidemiological surveillance, particularly focusing on the transmission of multiple serogroups of Nm among adolescents and the increasing exposure risk.

Objective To investigate the influence of the interaction between COX1 gene polymorphism and plate-let aggregation function on patients with recurrent ischemic stroke.Methods A total of 70 patients with recurrent isch-emic stroke from July 2020 to July 2023 were enrolled as observation group,and 70 healthy individuals who underwent physical examination during the same period of time were enrolled as control group.General data were compared between the two groups,and COX1 gene polymorphism was analyzed.The distribution of genotype and allele frequencies at COX1 gene polymorphism loci was determined and compared between the two groups.Platelet aggregation rate and its association and interaction with the susceptibility to recurrence of ischemic stroke were compared between the patients with different genotypes in the observation group.Results There were significant differences between the two groups in platelet count,COX1,and platelet aggregation rate(P<0.05).There were also significant differences between the two groups in the fre-quencies of CC gene,CT gene,and TT gene and the distribution of genotype C and genotype T at the rs1330344 locus of the COX1 gene(P<0.05).The risk of the recurrence of ischemic stroke in the patients who carried genotype CC at the rs1330344 locus of the COX1 gene was 1.872 times that in the patients who did not carry this genotype.In the observation group,the patients with genotype CC at the rs1330344 locus of the COX1 gene had the highest platelet aggregation rate,fol-lowed by those with genotype CT and genotype TT(P<0.05).The genotype at the rs1330344 locus of the COX1 gene was sig-nificantly correlated with platelet aggregation rate.The history of diabetes and hypertension,triglyceride,homocysteine,geno-type at the rs1330344 locus of the COX1 gene,and platelet aggregation rate were independent risk factors for recurrence of isch-emic stroke(P<0.05).There was a positive interaction between genotype CC at the rs1330344 locus of the COX1 gene and platelet aggregation rate in the susceptibility to recurrence of ischemic stroke(3.266<1.736×2.114,which was a sub-multiplicative model).Conclusion There is a positive interaction between genotype CC at the rs1330344 locus of the COX1 gene and platelet aggregation rate in the susceptibility to recurrence of ischemic stroke,and there is a significant increase in sus-ceptibility.Therefore,early prevention measures can be developed in clinical practice.

The development, progression, and curative efficacy of head and neck squamous cell carcinoma (HNSCC) are influenced by complex interactions between epithelial and immune cells. Nevertheless, the specific changes in the nature of these interactions and their underlying molecular mechanisms in HNSCC are not yet fully understood. Cuproptosis, a form of programmed cell death that is dependent on copper, has been implicated in cancer pathogenesis. However, the understanding of cuproptosis in the context of HNSCC remains limited. In this study, we have discovered that cuproptosis-related long non-coding RNAs (CRLs) known as JPX play a role in promoting the expression of the oncogene urokinase-type plasminogen activator (PLAU) by competitively binding to miR-193b-3p in HNSCC. The increased activity of the JPX/miR-193b-3p/PLAU axis in malignant epithelial cells leads to enhanced cell proliferation, migration, and invasion in HNSCC. Moreover, the overexpression of PLAU in tumor epithelial cells facilitates its interaction with the receptor PLAUR, predominantly expressed on macrophages, thereby influencing the abnormal epithelial-immune interactome in HNSCC. Notably, the JPX inhibitor Axitinib and the PLAU inhibitor Palbociclib may not only exert their effects on the JPX/miR-193b-3p/PLAU axis that impacts the malignant tumor behaviors and the epithelial-immune cell interactions but also exhibit synergistic effects in terms of suppressing tumor cell growth and arresting cell cycle by targeting epidermal growth factor receptor (EGFR) and cyclin-dependent kinase (CDK4/6) for the treatment of HNSCC.

Cancer seriously threatens human life and health, it is urgent for the development of rapid detection, precise localization and effective treatment of tumors. Chemical fluorescent probes that are sensitive to tumor-specific microenvironments have important significance in tumor theranostics and a variety of such probes have been developed. In this review, we classified chemical fluorescent probes that are sensitive to tumor microenvironments according to biological characteristics and microenvironmental changes while combining spectroscopy or response mechanisms, and systematically introduced the research progress of chemical fluorescent probes with sensitivity to hypoxia, low polarity, high viscosity, abnormal pH values and abundant reactive oxygen species in tumor microenvironments, in order to provide references for the development and applications of these probes.

Objective:To investigate the correlation between triglyceride-glucose (TyG) index and high on-treatment platelet reactivity (HTPR) during clopidogrel treatment in patients with ischemic stroke.Methods:Patients with ischemic stroke who received maintenance dose of clopidogrel (75 mg/d) in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2017 to March 2021 were retrospectively included. The highest quartile (Q4) of the TyG index was defined as insulin resistance. Platelet reactivity was assessed by thromboelastogram and clopidogrel HTPR was defined as the clot strength induced by adenosine diphosphate (MA ADP) >47 mm. Multivariate regression model was used to analyze the independent correlation between TyG index and platelet reactivity. Results:A total of 83 patients were included. The TyG index showed a linear correlation with MA ADP. The patients were divided into 4 groups according to the quartile of TyG index. The incidence of clopidogrel HTPR increased significantly with the increase of the quartile of the TyG index ( Ptrend=0.017). Multivariate analysis showed that there was a significant independent correlation between insulin resistance and clopidogrel HTPR (odds ratio 4.597, 95% confidence interval 1.285-16.446; P=0.019). Conclusions:In patients with ischemic stroke treated with clopidogrel, the incidence of clopidogrel HTPR gradually increases with the increase of the quartile of the TyG index. The insulin resistance assessed by the TyG index is independently associated with clopidogrel HTPR.

Objective:To investigate the biological mechanisms underlying the effect of the Chinese herbal medicine Oxalis cor-niculata on human prostate cancer PC-3 cells.Methods:Through in vitro experiment,we treated human prostate cancer PC-3 cells with different concentrations of Oxalis corniculata,assessed the viability of the cells by MTT assay,examined their apoptosis by flow cytometry,evaluated their migration and invasiveness by Transwell assay,and determined the expressions of the proteins p65,p-p65,IκBα and p-IκBα in the NF-κB pathway using protein imprinting technology.Results:Compared with the blank control,Oxalis cor-niculata significantly inhibited the proliferation and induced the apoptosis of the PC-3 cells(P＜0.05),suppressed their migration and invasiveness in a dose-dependent manner(P＜0.05),and upregulated the expression of IκBα and downregulated those of p-p65 and p-IKBα in the NF-κB pathway(P＜0.05).Conclusion:Oxalis corniculata can inhibit the proliferation,migration and inva-siveness and induce the apoptosis of human prostate cancer PC cells,which may be attributed to its abilities of inhibiting the expres-sions of p-p65 and p-IκBα and regulating the activity of the NF-κB pathway.

Objective:To investigate the application value of endoscopic ultrasound (EUS) in tumor staging of adenocarcinoma of the esophagogastric junction (AEG) after neoadjuvant concurrent chemoradiotherapy.Methods:The clinical data of 40 patients diagnosed with stage Ⅲ AEG and treated with neoadjuvant concurrent chemoradiotherapy from January 2016 to December 2021 in the First Affiliated Hospital of Hebei North University were retrospectively analyzed. EUS was used to perform preoperative tumor staging after neoadjuvant concurrent chemoradiotherapy to evaluate the therapeutic effect, and the consistency between EUS and postoperative pathological staging was analyzed.Results:In 40 AEG patients after neoadjuvant chemoradiotherapy, the EUS staging was stage yp-uT 2 in 12 cases, stage yp-uT 3 in 18 cases, and stage yp-uT 4 in 10 cases. The postoperative pathological staging was stage pT 1 in 2 cases, stage pT 2 in 14 cases, stage pT 3 in 12 cases, and stage pT 4 in 12 cases. Taking postoperative pathological results as the gold standard, the accuracy of EUS for T staging after neoadjuvant chemoradiotherapy was 62.5%, and the accuracy, sensitivity and specificity for stage T 2 were 58.3%, 50.0% and 80.8%, respectively. The accuracy, sensitivity and specificity for stage T 3 were 61.1%, 91.7% and 75.0%, respectively. The accuracy, sensitivity and specificity for stage T 4 were 70.0%, 58.3% and 89.3%, respectively. The Kappa value of the consistency test between yp-uT staging and pT staging was 0.453. The EUS staging of lymph nodes was stage yp-uN 0 in 15 cases, stage yp-uN 1 in 10 cases, stage yp-uN 2 in 10 cases, and stage yp-uN 3 in 5 cases. The postoperative pathological staging was stage pN 0 in 18 cases, stage pN 1 in 7 cases, stage pN 2 in 7 cases, and stage pN 3 in 8 cases. Taking postoperative pathological results as the gold standard, the accuracy rate of EUS for N staging after neoadjuvant chemoradiotherapy was 57.5%, and the accuracy, sensitivity and specificity of EUS for stage N 0 were 73.3%, 61.1% and 81.8%, respectively. The accuracy, sensitivity and specificity for stage N 1 were 50.0%, 71.4% and 84.8%, respectively. The accuracy, sensitivity and specificity for stage N 2 were 40.0%, 57.1% and 81.8%, respectively. The accuracy, sensitivity and specificity for stage N 3 were 60.0%, 37.5% and 93.8%, respectively. The Kappa value of the consistency test between yp-uN staging and pN staging was 0.409. Conclusions:EUS is not accurate for T staging in patients with stage Ⅲ AEG after neoadjuvant therapy, but has high sensitivity for stage T 3 and high specificity for stage T 4. EUS has low sensitivity for N staging in patients with stage Ⅲ AEG after neoadjuvant therapy, but has high specificity for stage N 3.

Background: The influencing factors of diabetic kidney disease (DKD) in Chinese patients with type 2 diabetes mellitus (T2DM) were explored to develop and validate a DKD diagnostic tool based on nomogram approach for patients with T2DM. Methods: A total of 2,163 in-hospital patients with diabetes diagnosed from March 2015 to March 2017 were enrolled. Specified logistic regression models were used to screen the factors and establish four different diagnostic tools based on nomogram according to the final included variables. Discrimination and calibration were used to assess the performance of screening tools. Results: Among the 2,163 participants with diabetes (1,227 men and 949 women), 313 patients (194 men and 120 women) were diagnosed with DKD. Four different screening equations (full model, laboratory-based model 1 [LBM1], laboratory-based model 2 [LBM2], and simplified model) showed good discriminations and calibrations. The C-indexes were 0.8450 (95% confidence interval [CI], 0.8202 to 0.8690) for full model, 0.8149 (95% CI, 0.7892 to 0.8405) for LBM1, 0.8171 (95% CI, 0.7912 to 0.8430) for LBM2, and 0.8083 (95% CI, 0.7824 to 0.8342) for simplified model. According to Hosmer-Lemeshow goodness-of-fit test, good agreement between the predicted and observed DKD events in patients with diabetes was observed for full model (χ2=3.2756, P=0.9159), LBM1 (χ2=7.749, P=0.4584), LBM2 (χ2=10.023, P=0.2634), and simplified model (χ2=12.294, P=0.1387). Conclusion LBM1, LBM2, and simplified model exhibited excellent predictive performance and availability and could be recommended for screening DKD cases among Chinese patients with diabetes.
