        Double Tract Reconstruction Reduces Reflux Esophagitis and Improves Quality of Life after Radical Proximal Gastrectomy for Patients with Upper Gastric or Esophagogastric Adenocarcinoma

        Xin Ji,Chenggen Jin,Ke Ji,Ji Zhang,Xiaojiang Wu,Ziyu Jia,Zhaode Bu,Jiafu Ji 대한암학회 2021 Cancer Research and Treatment Vol.53 No.3

        Purpose The aim of the present study was to compare the difference between double tract reconstruction and esophagogastrostomy.Materials and Methods Patients who underwent radical proximal gastrectomy with esophagogastrostomy or double tract reconstruction were included in this study.Results Sixty-four patients were included in this study and divided into two groups according to reconstruction method. The two groups were well balanced in perioperative safety and 3-year overall survival (OS). The rates of postoperative reflux esophagitis in the double tract reconstruction group and esophagogastrostomy group were 8.0% and 30.8%, respectively (p=0.032). Patients in the double tract reconstruction group had a better global health status (p < 0.001) and emotional functioning (p < 0.001), and complained less about nausea and vomiting (p < 0.001), pain (p=0.039), insomnia (p=0.003), and appetite loss (p < 0.001) based on the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire. Regarding the EORTC QLQ-STO22 questionnaire, patients in the double tract reconstruction group complained less about dysphagia (p=0.030), pain (p=0.008), reflux (p < 0.001), eating (p < 0.001), anxiety (p < 0.001), dry mouth (p=0.007), and taste (p=0.001). The multiple linear regression analysis showed that reconstruction method, postoperative complications, reflux esophagitis, and operation duration had a linear relationship with the global health status score.Conclusion Double tract reconstruction could better prevent reflux esophagitis and improve quality of life without scarifying perioperative safety or 3-year OS.

        Apoptosis induction by alantolactone in breast cancer MDA-MB- 231 cells through reactive oxygen species-mediated mitochondrion-dependent pathway

        Li Cui,Weiquan Bu,Jie Song,Liang Feng,Tingting Xu,Dan Liu,Wenbo Ding,Jianhua Wang,Changyang Li,Binge Ma,Yi Luo,Ziyu Jiang,Chengcheng Wang,Juan Chen,Jian Hou,Hong-mei Yan,Lei Yang,Xiao-bin Jia 대한약학회 2018 Archives of Pharmacal Research Vol.41 No.3

        Alantolactone is a sesquiterpene lactone isolatedfrom Inula helenium L. Although alantolactone possessesanti-inflammation and apoptosis-induction activities, theunderlying mechanism of anti-cancer effect on humanbreast cancer cells remains largely unknown. In this study,we explored the possibility of alantolactone as an apoptosis-inducing cytotoxic agent using MDA-MB-231 cells asin vitro model. Alantolactone significantly induced itsapoptosis, demonstrated by cell cycle analysis, annexinV-APC/7-AAD double staining and dUTP nick end labeling. Additionally, alantolactone triggered the mitochondrial-mediated caspase cascade apoptotic pathway, whichwas confirmed by increased Bax/Bcl-2 ratio, loss of MMP,release of cytc from mitochondria to cytoplasm, activationof caspase 9/3, and subsequent cleavage of PARP. Z-VADFMKpartially prevented apoptosis induced by alantolactone. Alantolactone provoked the production of ROS, whileNAC (a scavenger of ROS) reversed alantolactone-mediateddepolarization of MMP and apoptosis. Alantolactonemodulated the activities of MAPKs. As expected, cotreatmentwith SB203580, SP600125 or U0126 could reducedthe apoptotic rate. Furthermore, alantolactone decreasedthe protein expressions of p-NF-kB p65 and p-STAT3,increased p-c-Jun level in a dose-dependent manner. Thesefindings suggested that alantolactone possessed anticanceractivity via ROS-mediated mitochondrial dysfunctioninvolving MAPK pathway, and had an effect on the transcriptionfactors of NF-kB, AP-1 and STAT3.
