Objective To analyze the developmental trends and research hotspots of anoikis in cancer research from 2005 to 2024.Methods Relevant literature was retrieved from the Web of Sci-ence Core Collection.Visualization tools including CiteSpace,VOSviewer and SCImago Graphica were employed to analyze publication volume,countries,institutions,authors,journals,keywords and other bibliometric indicators.Results A total of 2,252 articles were included in this study,showing an overall upward trend in publication volume,with a notable increase after 2012.China and the United States ranked highest in terms of publication volume and citation frequency.Representative institutions included Shanghai Jiao Tong University,Chulalongkorn University and MD Anderson Cancer Center,while a representative scholar was CHANVORACHOTE Pithi.The core journal was Oncogene.Keyword and co-citation analyses revealed that research focused on genetic characteristics,cancer treatment,prognostic prediction and metabolic reprogramming,with core terms including"ex-pression""metastasis"and"anoikis".Conclusion Research interest in the field of anoikis contin-ues to rise,with future directions focusing on drug resistance mechanisms,the tumor microenvironment,immunotherapy,signaling pathways and epithelial-mesenchymal transition(EMT).

Objective:To investigate the effect of tocilizumab (TCZ) on ventricular arrhythmias (VAs) after myocardial infarction (MI) in Sprague-Dawley rats and explore its potential mechanism.Methods:The random number table method was used to divide 32 adult male Sprague-Dawley rats into 4 groups: Sham group, TCZ group, MI group and MI+TCZ group, with 8 rats in each group. The MI model was established by ligation of the left anterior descending branch of the coronary artery in the MI and MI+TCZ groups, and only sutured without ligation in the Sham and TCZ groups. TCZ was injected into the left superior cervical ganglion (SCG) of rats in the TCZ and MI+TCZ groups after successful modeling or sham operation, and the same amount of normal saline was injected in the Sham and MI groups. 24 h after successful modeling, ECG of rats in each group was recorded, heart rate variability (HRV, including low frequency power (LF), high frequency power (HF), LF/HF ratio), QT interval, QTc interval were calculated, and left ventricular effective refractory period (ERP) and VA inducibility were measured. Myocardial infarct size and tissue changes were observed with triphenyl tetrazolium chloride staining and HE staining. Real-time PCR analysis was used to detect the messager RNA (mRNA) expression of interleukin-6 (IL-6) and signal transducer and activator of transcription (STAT) 3 in SCG and potassium voltage-gated channel subfamily D member 2 (Kcnd2) in myocardial infarction periphery. The expression of c-fos in SCG was detected by immunofluorescence staining.Results:Compared with Sham group and MI+TCZ group, rats in MI group had higher LF and LF/HF ratio, longer QT interval and QTc interval, more VAs induced, lower HF and shorter ERP ( P all<0.05). Triphenyl tetrazolium chloride staining and HE staining showed that rats in the Sham and TCZ groups had normal myocardial tissue structure, those in the MI group had severe myocardial injury, and those in the MI+TCZ group had less myocardial injury than those in the MI group. Real-ime PCR analysis showed that compared with Sham group and MI+TCZ group, mRNA expression levels of IL-6 and STAT3 in SCG of rats in MI group were higher, and mRNA expression level of myocardial Kcnd2 was lower ( P all<0.05). Immunofluorescence staining showed that the content of c-fos in SCG of rats in MI group was higher than that of Sham group and MI+TCZ group ( P all<0.05). Conclusions:TCZ may reduce neural activity of the SCG after MI by inhibiting the IL-6/STAT3 signaling pathway, thereby alleviating myocardial injury and inhibiting VAs.
