Esophageal cancer is a unique malignant disease in China. A fundamental difference exists between the Chinese population and the western population on esophageal cancer in terms of epidemiology, histogenesis, and carcinogenic risk factors. Therefore, ap-plying the western academic achievements to Chinese is difficult. Thus, Chinese scientists have the responsibility to conquer esopha-geal cancer in China. This article reviews the progress of esophageal cancer focused on the molecular mechanism for interactions of ge-netic and environmental risk factors and human esophageal multistage carcinogenesis.

Aim To investigate the protective effects of Diterpene Ginkgolides Meglumine Injection(DGMI)on SY5 Y cells damaged by oxygen-glucose deprivation and its functional mechanisms.Methods After 4 h of OGD,the cells were treated with 25 mg·L-1 drugs for 1 h.Subsequently,cell viabilities were measured by cell counting kit-8(CCK-8 kit)and cell apoptosis was measured by flow cytometric analysis.Furthermore, the mitochondrial membrane potential was detected by rhodamine123 staining.The levels of phospho-p38, phospho-p53,Bcl-2,Bax and cleaved caspase-9/3 were evaluated by western blot.Results DGMI signif-icantly increased the cell viabilities of SY5 Y cells dam-aged by OGD,and reduced OGD-elicited dissipation of mitochondrial membrane potential and cell apoptosis. Furthermore,DGMI also reduced p-p38,p-p53,Bax/Bcl-2 ratio,cleaved caspase-9 and cleaved caspase-3. Conclusion DGMI shows good neuroprotective effects on SY5 Y cells after oxygen-glucose deprivation.The underlying mechanisms may be associated with the sup-pression of p38/p53/Bcl-2 /caspase-9/caspase-3 sig-naling pathway.

Pro-inflammatory cytokines selectively induce specific signals to regulate host responses. Since the immunological imbalance caused by abnormal release of cytokines is involved in the development of many diseases, cytokine-specific detections are of great clinical significance for disease diagnosis and efficacy monitoring. Aptamers are single-stranded nucleic acid sequences which can bind to the target with high selectivity and affinity. It has attracted much attention in the development of novel aptamers-based methods for the detection of specific biomarkers of inflammatory diseases. This paper reviewed recent advances in electrochemical and optical aptasensors for the detection of tumor necrosis factor-α, interleukin-6, transforming growth factor-β, interferon-γ and interleukin-8. The findings offered valuable insights into the clinical application potential and challenges of nucleic acid aptamers in the detection of key inflammatory cytokines, providing a meaningful reference for the development of aptamer-based cytokines sensitive detection point-of-care testing equipment and novel diagnostic strategies for inflammatory disorders.

Objective:To investigate the clinical pathological and epidemiological characteristics of primary esophageal malignant melanoma (PMME).Methods:The clinical pathology data of 180 PMME patients in the esophageal cancer database of the key laboratory of esophageal cancer research in Henan Province from 1973 to 2016 were collected, of which 136 were male, aged (58.5±9.0) years, 44 were female, aged (56.7±12.2) years. Kaplan-Meier and Log rank test were used for survival analysis, Cox regression scale model was used for risk factor analysis.Results:The incidence of PMME is 0.036% (180/500, 000), mostly were male (about 3∶1 for men: female). The common sites of PMME were the lower part of the esophagus (48.9%, 85/174), followed by the middle section of the esophagus (46.0%, 80/174) and the upper part of the esophagus (5.2%, 9/174). No black particles were seen in the PMME cells of 3 patients under microscope, and strong positive expressions of Melan-A and HMB453 were observed in these 3 patients by immunohistochemical results. Of the 129 patients who had a routine preoperative esophageal biopsy, 69 were undiagnosed with PMME (53.5%). The medium survival time of the whole group was 7.9 months, and the survival rates of 1, 2, 3, 5 years were 25.0%, 7.9%, 6.6% and 1.3%, respectively. The univariate analysis showed that N, M, TNM phase and radiotherapy were related to the overall survival of patients ( P<0.05). Multivariate analysis showed that TNM phase and radiotherapy were the independent risk factors for overall survival of patients ( P<0.05). Conclusions:PMME is more common in men, the common site of the disease is the lower part of the esophagus. The preoperatively missed diagnosis rate of Chinese PMME is high. TNM phase and radiotherapy are the independent risk factors for overall survival of patients.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.
