      • Changes in Markers of Liver Function in HCV 1b Patients with Compensated Cirrhosis Treated with Ombitasvir/Paritaprevir/ Ritonavir plus Dasabuvir with Ribavirin

        ( Jeong Heo ),( Yan Luo ),( Wan-long Chuang ),( Jidong Jia ),( Kwang-hyub Han ),( Ming-lung Yu ),( Hong Tang ),( Young-suk Lim ),( Cheng-yuan Peng ),( Min Xu ),( Maorong Wang ),( Bo Fu ),( Niloufar Mo 대한간학회 2017 춘·추계 학술대회 (KASL) Vol.2017 No.1

        Aims: Patients chronically infected with HCV are at risk of developing extrahepatic manifestations of HCV as well as progressing to compensated or decompensated cirrhosis and HCC. Although current treatments have high rates of SVR, relatively little is known about possible regression of liver fibrosis after achieving an SVR. The ONYX-II trial examined the efficacy and safety of ombitasvir/paritaprevir/ritonavir plus dasabuvir + ribavirin (RBV) in Asian patients with HCV genotype 1b infection and compensated cirrhosis. Here we report changes in key markers of liver fibrosis and function. Methods: Patients with chronic HCV GT1b infection and compensated cirrhosis were enrolled in China, South Korea and Taiwan and received 12 weeks of OBV/PTV/r (25 mg/150 mg/100 mg once daily) and DSV (250 mg twice daily) with weight-based RBV. The primary objective of ONYX-II was to assess efficacy (SVR12) and safety of the regimen. Changes in markers of liver fibrosis and function between baseline (BL) and post-treatment week (PTW) 12 are presented. Results: Overall, 104 patients were enrolled and treated in ONYX-II. All patients (104/104, 100%) achieved SVR12. BL and PTW12 data for FibroTest score, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, albumin, platelet count and alpha fetoprotein (AFP) are shown in Table 1. All selected parameters showed numerical improvements between BL and PTW12. Mean ALT and AST levels returned to within normal range and FibroTest scores demonstrated a numerical improvement, suggesting improvement in liver status. The complete set of data between BL and PTW12 will be presented for these parameters and other liver composite parameters at the conference. Conclusions: Measurement of key liver function markers during the ONYX-II trial showed a numerical improvement within 12 weeks of completion of treatment in HCV GT1b-infected patients with compensated cirrhosis. Further follow-up of these patients will determine the long-term durability of these changes.

        Cr(VI) Resistance and Removal by Indigenous Bacteria Isolated from Chromium-Contaminated Soil

        ( Dong Yan Long ),( Xian Jin Tang ),( Kuan Cai ),( Guang Cun Chen ),( Chao Feng Shen ),( Ji Yan Shi ),( Ling Gui Chen ),( Ying Xu Chen ) 한국미생물 · 생명공학회 2013 Journal of microbiology and biotechnology Vol.23 No.8

        The removal of toxic Cr(VI) by microorganisms is a promising approach for Cr(VI) pollution remediation. In the present study, four indigenous bacteria, named LY1, LY2, LY6, and LY7, were isolated from Cr(VI)-contaminated soil. Among the four Cr(VI)-resistant isolates, strain LY6 displayed the highest Cr(VI)-removing ability, with 100 mg/l Cr(VI) being completely removed within 144 h. It could effectively remove Cr(VI) over a wide pH range from 5.5 to 9.5, with the optimal pH of 8.5. The amount of Cr(VI) removed increased with initial Cr(VI) concentration. Data from the time-course analysis of Cr(VI) removal by strain LY6 followed first-order kinetics. Based on the 16S rRNA gene sequence, strain LY6 was identified as Pseudochrobactrum asaccharolyticum, a species that had never been reported for Cr(VI) removal before. Transmission electron microscopy and energy dispersive X-ray spectroscopy analysis further confirmed that strain LY6 could accumulate chromium within the cell while conducting Cr(VI) removal. The results suggested that the indigenous bacterial strain LY6 would be a new candidate for potential application in Cr(VI) pollution bioremediation.

      • Cyclooxygenase-2 Promoter 765C Increase of Digestive Tract Cancer Risk in the Chinese Population: a Meta-analysis

        Xu, Yan-Song,Zhao, Bo,Long, Chen-Yan,Li, Hui,Lu, Xing,Liu, Gang,Tang, Xiao-Zhun,Tang, Wei-Zhong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.11

        Background: To evaluate relationship between the cyclooxygenase-2 promoter 765G/C polymorphism and digestive cancer risk in China. Materials and Methods: A literature search through February 2014 was performed using PubMed, Chinese Biomedical Literature Database (CBM) and China National Knowledge Infrastructure (CNKI) databases, and a meta-analysis was performed with RevMan 5.2 software for odds ratios and 95%CIs. Results: In total, 9 articles with 3,263 cases and 4,858 controls were included in this meta-analysis. The pooled OR (95%CIs) in the co-dominant model (GC vs GG) was 1.56 [1.19, 2.06], and in the dominant model ((CC+GC) vs GG), the pooled OR was 1.59 [1.21, 2.09] in overall cancers. In the subgroup analysis, stratified by cancer type, significant associations were found that the-765C allele had increased pancreatic cancer and gastric risk. No significant liver cancer and colorectal cancer risk of COX-2 -765G/C polymorphism was found. Conclusions: These findings suggest that COX-2-765*C is related to cancer susceptibility and may increase gastric and pancreatic cancer risk.

        Panax ginseng and its ginsenosides: potential candidates for the prevention and treatment of chemotherapy-induced side effects

        Yan Wan,Jing Wang,Jin-feng Xu,Fei Tang,Lu Chen,Yu-zhu Tan,Chao-long Rao,Hui Ao,Cheng Peng 고려인삼학회 2021 Journal of Ginseng Research Vol.45 No.6

        Chemotherapy-induced side effects affect the quality of life and efficacy of treatment of cancer patients. Current approaches for treating the side effects of chemotherapy are poorly effective and may causenumerous harmful side effects. Therefore, developing new and effective drugs derived from natural nontoxiccompounds for the treatment of chemotherapy-induced side effects is necessary. Experimentsin vivo and in vitro indicate that Panax ginseng (PG) and its ginsenosides are undoubtedly non-toxic andeffective options for the treatment of chemotherapy-induced side effects, such as nephrotoxicity, hepatotoxicity,cardiotoxicity, immunotoxicity, and hematopoietic inhibition. The mechanism focus on antioxidation,anti-inflammation, and anti-apoptosis, as well as the modulation of signaling pathways, suchas nuclear factor erythroid-2 related factor 2 (Nrf2)/heme oxygenase-1 (HO-1), P62/keap1/Nrf2, c-jun Nterminalkinase (JNK)/P53/caspase 3, mitogen-activated protein kinase (MEK)/extracellular signalregulatedkinases (ERK), AMP-activated protein kinase (AMPK)/mammalian target of rapamycin(mTOR), mitogen-activated protein kinase kinase 4 (MKK4)/JNK, and phosphatidylinositol 3-kinase(PI3K)/AKT. Since a systemic review of the effect and mechanism of PG and its ginsenosides onchemotherapy-induced side effects has not yet been published, we provide a comprehensive summarizationwith this aim and shed light on the future research of PG.

        Isolation and Molecular Characterization of a New CRT Binding Factor Gene from Capsella bursa-pastoris

        ( Xing Long Wang ),( Li Liu ),( Si Xiu Liu ),( Xiao Qing Sun ),( Zhong Xiang Deng ),( Yan Pi ),( Xiao Fen Sun ),( Ke Xuan Tang ) 생화학분자생물학회 2004 BMB Reports Vol.37 No.5

        A new CRT binding factor (CBF) gene designated Cbcbf25 was cloned from Capsella bursa pastoris, a wild grass, by the rapid amplification of cDNA ends (RACE). The full-length cDNA of Cbcbf25 was 898 bp with a 669 bp open reading frame (ORF) encoding a putative DRE/CRT (LTRE)-binding protein of 223 amino acids. The predicted CbCBF25 protein contained a potential nuclear localization signal (NLS) in its N-terminal region followed by an AP2 DNA-binding motif and a possible acidic activation domain in the C-terminal region. Bioinformatic analysis revealed that Cbcbf25 has a high level of similarity with other CBF genes like cbfl, cbf2, and cbf3 from Arabidopsis thaliana, and Bncbf5, Bncbf7, Bncbfl6, and Bncbfl7 from Brassica napus. A cold acclimation assay showed that Cbcbf25 was expressed immediately after cold triggering, but this expression was transient, suggesting that it concerns cold acclimation. Our study implies that Cbcbf25 is an analogue of other CBF genes and may participate in cold-response, by for example, controlling the expression of cold-regulated genes or increasing the freezing tolerance of plants.

      • Anisotropic Patterns of Liver Cancer Prevalence in Guangxi in Southwest China: Is Local Climate a Contributing Factor?

        Deng, Wei,Long, Long,Tang, Xian-Yan,Huang, Tian-Ren,Li, Ji-Lin,Rong, Min-Hua,Li, Ke-Zhi,Liu, Hai-Zhou Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.8

        Geographic information system (GIS) technology has useful applications for epidemiology, enabling the detection of spatial patterns of disease dispersion and locating geographic areas at increased risk. In this study, we applied GIS technology to characterize the spatial pattern of mortality due to liver cancer in the autonomous region of Guangxi Zhuang in southwest China. A database with liver cancer mortality data for 1971-1973, 1990-1992, and 2004-2005, including geographic locations and climate conditions, was constructed, and the appropriate associations were investigated. It was found that the regions with the highest mortality rates were central Guangxi with Guigang City at the center, and southwest Guangxi centered in Fusui County. Regions with the lowest mortality rates were eastern Guangxi with Pingnan County at the center, and northern Guangxi centered in Sanjiang and Rongshui counties. Regarding climate conditions, in the 1990s the mortality rate of liver cancer positively correlated with average temperature and average minimum temperature, and negatively correlated with average precipitation. In 2004 through 2005, mortality due to liver cancer positively correlated with the average minimum temperature. Regions of high mortality had lower average humidity and higher average barometric pressure than did regions of low mortality. Our results provide information to benefit development of a regional liver cancer prevention program in Guangxi, and provide important information and a reference for exploring causes of liver cancer.

        The Pattern of Time to Onset and Resolution of Immune-Related Adverse Events Caused by Immune Checkpoint Inhibitors in Cancer: A Pooled Analysis of 23 Clinical Trials and 8,436 Patients

        Si-Qi Tang,Ling-Long Tang,Yan-Ping Mao,Wen-Fei Li,Lei Chen,Yuan Zhang,Ying Guo,Qing Liu,Ying Sun,Cheng Xu,Jun Ma 대한암학회 2021 Cancer Research and Treatment Vol.53 No.2

        Purpose The occurrence pattern of immune-related adverse events (irAEs) induced by immune checkpoint inhibitor (ICI) in cancer treatment remains unclear. Materials and Methods Phase II-III clinical trials that evaluated ICI-based treatments in cancer and were published between January 2007 and December 2019 were retrieved from public electronic databases. The pooled median time to onset (PMT-O), resolution (PMT-R), and immune-modulation resolution (PMT-IMR) of irAEs were generated using the metamedian package of R software.Results Twenty-two eligible studies involving 23 clinical trials and 8,436 patients were included. The PMT-O of all-grade irAEs ranged from 2.2 to 14.8 weeks, with the longest in renal events. The PMT-O of grade ≥ 3 irAEs was significantly longer than that of all-grade irAEs induced by programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1) inhibitors (27.5 weeks vs. 8.4 weeks, p < 0.001) and treatment of nivolumab (NIV) plus ipilimumab (IPI) (7.9 weeks vs. 6.0 weeks, p < 0.001). The PMT-R of all-grade irAEs ranged from 0.1 to 54.3 weeks, with the shortest and longest in hypersensitivity/infusion reaction and endocrine events, respectively. The PMT-IMR of grade ≥ 3 irAEs was significantly shorter than that of all-grade irAEs caused by PD-1/PD-L1 blockade (6.9 weeks vs. 40.6 weeks, p=0.002) and NIV+IPI treatment (3.1 weeks vs. 5.9 weeks, p=0.031).Conclusion This study revealed the general and specific occurrence pattern of ICI-induced irAEs in pan-cancers, which was deemed to aid the comprehensive understanding, timely detection, and effective management of ICI-induced irAEs.

      • Serum Carbohydrate Antigen 19-9 as an Indicator of Liver Metastasis in Colorectal Carcinoma Cases

        Dong, Hang,Tang, Jie,Li, Long-Hao,Ge, Jun,Chen, Xin,Ding, Jing,Men, Hai-Tao,Luo, Wu-Xia,Du, Yang,Li, Cong,Zhao, Feng,Chen, Ye,Cheng, Ke,Liu, Ji-Yan Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.2

        Purpose: The liver is the organ to which colorectal carcinomas (CRCs) most commonly metastasize, and surgical resection has been established as the most effective and potentially curative treatment for CRC with liver metastasis (LM). Therefore, surveillance of LM is vital for improvement of prognosis of CRC patients. In this study, we aimed to explore the potential value of carbohydrate antigen 19-9 (CA 19-9), carcinoembryonic antigen (CEA), and marker enzymes in indicating LM with CRC. Methods: Three groups of eligible patients with metastatic cancers were retrospectively included: CRC patients with LM (CRC-LM) or without LM (CRC-NLM), and non-CRC patients with LM (NCRC-LM). All metastatic lesions were identified by CT or MRI. Data on characteristics of the patients, the primary site, the locations of metastasis, CA 19-9, CEA, and biochemical parameters were collected for analysis. Results: A total of 493 patients were retrospectively included. More alcohol consumption was found in CRC-LM than CRC-NLM. Some biochemical enzymes were found to be significantly higher in groups with LM than without (CRC-LM or NCRC-LM v.s CRC-NLM). Both CEA and CA 19-9 were much higher in CRC-LM than CRC-NLM or NCRC-LM. For CRC patients, CA 19-9, ${\gamma}$-glutamyl transpeptidase, CEA and alcohol consumption were identified as independent factors associated with LM. Conclusion: Our analysis suggested the CA 19-9 might be a potential valuable indicator for LM of CRC in the clinic.

        Port-Site Metastases and Chimney Effect of B-Ultrasound-Guided and Laparoscopically-Assisted Hyperthermic Intraperitoneal Perfusion Chemotherapy

        Ming-Chen Ba,Hui Long,Xiang-Liang Zhang,Yuan-Feng Gong,Zhao-Fei Yan,Shuai Wang,Yun-Qiang Tang,Shu-Zhong Cui 연세대학교의과대학 2017 Yonsei medical journal Vol.58 No.3

        Purpose: CO2 leakage along the trocar (chimney effect) has been proposed to be an important factor underlying port-site metastasisafter laparoscopic surgery. This study aimed to test this hypothesis by comparing the incidence of port-site metastasis betweenB-ultrasound-guided and laparoscopically-assisted hyperthermic intraperitoneal perfusion chemotherapy (HIPPC). Materials and Methods: Sixty-two patients with malignant ascites induced by gastrointestinal or ovarian cancer were divided into two groups to receive either B-ultrasound-guided or laparoscopically-assisted HIPPC. Clinical efficacy was assessed from the objective remission rate (ORR), the Karnofsky Performance Status (KPS) score, and overall survival. The incidence of port-site metastasis was compared between the two groups. Results: Patients in the B-ultrasound (n=32) and laparoscopy (n=30) groups were comparable in terms of age, sex, primary diseasetype, volume of ascites, and free cancer cell (FCC)-positive ascites. After HIPPC, there were no significant differences between the B-ultrasound and laparoscopy groups in the KPS score change, ORR, and median survival time. The incidence of port-site metastasis after HIPPC was not significantly different between the B-ultrasound (3 of 32, 9.36%) and laparoscopy (3 of 30, 10%) groups, but significantly different among pancreatic, gastric, ovarian, and colorectal cancer (33.33, 15.79, 10.00, and 0.00%, p<0.001). Conclusion: The chimney effect may not be the key reason for port-site metastasis after laparoscopy. Other factors may play a role, including the local microenvironment at the trocar site and the delivery of viable FCCs (from the tumor or malignant ascites) to the trauma site during laparoscopic surgery.
