Objective To investigate the role of CCCTC-binding factor(CTCF)in the development of oxaliplatin(OXA)-induced gastric cancer drug-tolerant cells(DTCs)and to preliminarily elucidate its underlying mechanisms.Methods The DTCs model of gastric cancer was established by treating MGC803 cells with OXA.Overexpression and knockdown of CTCF in MGC803 cells were performed to observe their effects on the formation of DTCs in gastric cancer.Additionally,Bcl2-like protein 1(BCL2L1)was knocked down in CTCF-overexpressing cells,and its impact on DTCs formation was evaluated.Flow cytometry was used to analyze the effects of varying CTCF/BCL2L1 expression levels on the apoptosis of gastric cancer cells under OXA treatment.Immunohistochemistry(IHC)was employed to detect the expression levels of CTCF/BCL2L1 in gastric cancer tissues,and the therapeutic outcomes of neoadjuvant chemotherapy in patients with different CTCF/BCL2L1 expression levels were assessed.Results Gastric cancer DTCs can be obtained following a regimen of continuous treatment of MGC803 cells with a specific concentration of oxaliplatin(OXA,1.5 μmol/L)for 5 days,followed by an additional 5-day culture period post-treatment cessation.The upregulation of CTCF has been shown to facilitate the formation of DTCs in gastric cancer,whereas its downregulation inhibits this process(P<0.05).In MGC803 gastric cancer cells,the expression level of BCL2L1 is positively correlated with that of CTCF.Knockdown of BCL2L1 in MGC803 cells overexpressing CTCF can reverse the pro-DTC formation effect of CTCF(P<0.05).Overexpression of CTCF confers resistance to OXA-induced apoptosis in gastric cancer cells,and this anti-apoptotic effect can be reversed by BCL2L1 knockdown in MGC803 cells overexpressing CTCF(P<0.05).In the tumor tissues of the majority of gastric cancer patients,the expression levels of BCL2L1 are positively correlated with those of CTCF,and the efficacy of neoadjuvant chemotherapy is notably reduced in patients with high expression of the CTCF/BCL2L1 axis compared to those with low expression(P<0.05).Conclusion CTCF promotes the formation of OXA-related gas-tric cancer DTCs by upregulating BCL2L1 expression and inhibiting apoptosis,making the CTCF/BCL2L1 axis a potential therapeutic target for DTCs in gastric cancer.

Oral cancer(OC)is a common malignant tumor and its incidence and mortality rate is increasing year by year.According to statistics,there are over 500,000 new cases worldwide every year,and most patients face treatment challenges.Electrospinning technology(ES)is a method for preparing nanofibers by driving the polymer in solution to form nanoscale fibers through an electric field.Since its discovery in the 1930s,it has received widespread attention and application.This article reviews the application of ES in the treatment of OC.The principles and preparation process of ES are induced,its application research in treating OC is elaborated,and the challenges faced by ES in OC treatment research are analyzed.Finally,the future development is discussed.

Hand degloving injury represents one of the most severe forms of hand trauma, characterised by challenging treatment and a complex prognostic outcome. It is crucial to effectively utilise the degloved tissues in emergency or primary repair of a hand degloving injury. This consensus provides a comprehensive review of the existing literature on definition, classification, emergency assessment, debridement, judgment of skin viability, in situ repair of the degloved skin, and adjunctive treatment for degloving injury of hand. Based on conclusion of both domestic and international experiences, this expert consensus on the classification of hand degloving injury and the emergency repair with the avulsed skin is established, aiming to provide a guidance to surgeons on standardised treatment strategy and improve the management of hand degloving injury.

Objective:To discuss how to construct the medical insurance access for medical service items based on Health Tech-nology Assessment(HTA)applicable to China.Methods:This study consolidated the current medical insurance access in some prov-inces and cities from China and identified deficiencies through the expert interview.We summarized the experience and indicators contained in the HTA report in UK and Singapore by using literature analysis.Results:In most regions of China,the management of medical services price is gradually moving from exclusion items based on certain conditions to access approach,lacking of tools for assessment.In UK and Singapore,the medical insurance access mechanism mainly consists of subject selection,scoping,HTA imple-mentation and decision-making,in the HTA report,with the data including clinical evidence,cost evidence and budget impact on health system,etc.Conclusion:Building an evidence-based health policy decision-making framework through multi-criteria deci-sion analysis and the construction of medical insurance access mechanism based on HTA can be achieved by developing national guidelines,multi-scenario HTA systems,and enhancing the supervision on the process of HTA.
