16Immune mechanisms of Concanavalin A model of autoimmune hepatitis显示文摘As a chronic inflammatory disease of the liver,the pathogenic mechanisms of autoimmune hepatitis (AIH) have not yet been elucidated,with prognosis and diagnosis remaining unsatisfied.Currently the only viable treatments of AIH are immunosuppressant application and liver transplantation.It is considered that lack of good animal AIH models is the main reason for the shortage of a simple and efficient cure.The Concanavalin A (Con A) model is a typical and well established model for investigating T-cell and macrophage dependent liver injury in mice,which closely mimics the pathogenesis mechanisms and pathological changes of patients,and is regarded as the best experimental model for AIH research so far.In this paper we eluci-dated the pathogenic mechanisms of AIH and the evolution of relative animal models.We go on to further focus on Con A-induced liver injury from the point of immunological mechanisms and the change of cytokine levels.Finally,we manifested the clinical significance of the AIH animal models and the challenges they would meet during their future development.Hai-Xia Wang Man Liu Shun-Yan Weng Jing-Jing Li Chao Xie Hong-Lin He Wen Guan Yun-Sheng Yuan Jin Gao 2012World Journal of Gastroenterology2012,18,2:52
172018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
18High-dose Iodized Oil Transcatheter Arterial Chemoembolization For Patients with Large Hepatocellular Carcinoma显示文摘AIM:To conduct a randomized trial to evaluate the role ofusing high-dose iodized oil transcatheter arterialchemosmbolization(TACE)in the treatment of largehepatocellular carcinoma(HCC).METHODS:From January 1993 to June 1998,473 patientswith unresectable hepatocellular carcinoma ware divided intotwo groups:216 patients in group A received more than20mL iodized oil during the first TACE treatment;257patients in group B received 5-15mL iodized oil in the sameway.The Child's classification and ICG-R15 for evaluatingthe liver function of the patients ware done before thetreatment.During the TACE procedure the catheters wasinserted into the target artery selectively and the tumorvessels ware demonstrated with contrast medium in thehepatic angiography.The anticancar drugs mixed withiodized oil(Lipiodol)ware Epirubicin and Mitomycin.Ingroup A,112 cases received 20-29mL Lipiodol in the firstprocedure,85 cases 30-39mL,19 cases more than 40mL.The largest dose was 53 mL and the average dose was28.3mL.In group B,119 cases received 5-10mL Lipiodol,138 cases received 11-15mL,and the average dose was11.8mL.RESULTS:High-dose Lipiodol chemoembolization causedtolerable side effects and a little hurt to the liver function inthe patients with Child grade A or ICG-R15<20.But thepatients with child grade B or ICG-R15>20 had higher risk ofliver failure after high-dose TACE.More type Ⅱ and type Ⅱlipiodol accumulations in CT scan after 4 weeks of TACEware seen in the group A patients than those in the group Bpatients(P<0.01).The resection rate and complete tumornecrosis rate in group A ware higher than those of group B(P<0.05).The 1-,2-,3-year survival rates of group Apatients with Child grade A ware 79.2%,51.8% and 34.9%,respectively,better then those of group B(P<0.001).CONCLUSION:High-dose Lipiodol can result in morecomplete tumor necrosis by blocking both arteries and small portal veins of the tumor.High-dose TACE for treatment oflarge and hypervascular hepatocallular carcinoma ispractically acceptable with the better effect than the routinedose.For the patients with large and hypervascular tumor ofChild grade A liver function or ICG-R15 less than 20%,oilychemoembolization with 20-40mL Lipiodol is recommended.Min-Shan Chen Jin-Qing Li Ya-Qi Zhang Yun-Fei Yuan Yong-Ping Guo Xiao-Jun Lin Guo-Hui Lim Department of Hepatobiliary Cancer Center of Sun Yet-sen University of Medical Sciences,Guangzhou 510060,China Li-Xia Lu Wei-Zhang Zhang Department of Radiology Cancer Center of Sun Yet-sen University of Medical Sciences,Guangzhou 510060,China 2002World Journal of Gastroenterology2002,8,1:58
19Contrasting trends of PM2.5 and surface-ozone concentrations in China from 2013 to 2017显示文摘Although much attention has been paid to investigating and controlling air pollution in China,the trends of air-pollutant concentrations on a national scale have remained unclear.Here,we quantitatively investigated the variation of air pollutants in China using long-term comprehensive data sets from 2013 to 2017,during which Chinese government made major efforts to reduce anthropogenic emission in polluted regions.Our results show a significant decreasing trend in the PM2.5 concentration in heavily polluted regions of eastern China,with an annual decrease of〜7%compared with measurements in 2013.The measured decreased concentrations of SO2>NO2 and CO(a proxy for anthropogenic volatile organic compounds)could explain a large fraction of the decreased PM2.5 concentrations in different regions.As a consequence;the heavily polluted days decreased significantly in corresponding regions.Concentrations of organic aerosol;nitrate;sulfate,ammonium and chloride measured in urban Beijing revealed a remarkable reduction from 2013 to 2017;connecting the decreases in aerosol precursors with corresponding chemical components closely.However;surface-ozone concentrations showed increasing trends in most urban stations from 2013 to 2017;which indicates stronger photochemical pollution.The boundary-layer height in capital c让ies of eastern China showed no significant trends over the Beijing-Tianjin-Hebei,Yangtze River Delta and Pearl River Delta regions from 2013 to 2017;which confirmed the reduction in anthropogenic emissions.Our results demonstrated that the Chinese government was successful in the reduction of particulate matter in urban areas from 2013 to 2017,although the ozone concentration has increased significantly;suggesting a more complex mechanism of improving Chinese air quality in the future.Yonghong Wang Wenkang Gao Shuai Wang Tao Song Zhengyu Gong Dongsheng Ji Lili Wang Zirui Liu Guiqian Tang Yanfeng Huo Shili Tian Jiayun Li Mingge Li Yuan Yang Biwu Chu Tuukka Petaja Veli-Matti Kerminen Hong He Jiming Hao Markku Kulmala Yuesi Wang Yuanhang Zhang 2020National Science Review2020,7,8:51
