7Concentration and source identification of polycyclic aromatic hydrocarbons and phthalic acid esters in the surface water of the Yangtze River Delta,China显示文摘The pollution from polycyclic aromatic hydrocarbons(PAHs) and phthalic acid esters(PAEs) in the surface water of the rapidly urbanized Yangtze River Delta region was investigated.Fourteen surface water samples were collected in June 2010.Water samples were liquid-liquid extracted using methylene chloride and analyzed by gas chromatography-mass spectrometry.Concentrations of PAHs and PAEs ranged 12.9-638.1 ng/L and 61-28550 ng/L,respectively.Fluoranthene,naphthalene,pyrene,phenanthrene,di-2ethylhexyl phthalate,and di-n-butyl phthalate were the most abundant compounds in the samples.The water samples were moderately polluted with benzo[a]pyrene according to China's environmental quality standard for surface water.The two highest concentrations of PAHs and PAEs occurred in samples from Taihu Lake,Wuxi City and the western section of Yangchenghu Lake.Potential sources of pollution at S7 were petroleum combustion and the plastics industry,and at Yangchenghu Lake were petroleum combustion and domestic waste.Pollution in samples from the Beijing-Hangzhou Grand Canal originated from diesel engines.There were no obvious sources of pollution for the other water samples.These results can be used as reference levels for future monitoring programs of pollution from PAHs and PAEs.Lifei Zhang Liang Dong Lijun Ren Shuangxin Shi Li Zhou Ting Zhang Yeru Huang 2012Journal of Environmental Sciences2012,24,2:56
82018 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
9Study of the mechanisms of acupuncture and moxibustion treatmentfor ulcerative colitis ratsinview of the gene expression of cytokines显示文摘AIM To observe the effect of acupuncture and moxibustion on the expression of IL 1β and IL 6 mRNA in ulcerative colitis rats. METHODS The SD rat ulcerative colitis model was created by immunological method associated with local stimulation. Colonic mucosa was prepared from human fresh surgical colonic specimens, homogenized by adding appropriate amount of normal saline and centrifuged at 3000*!r/*!min . The supernatant was collected for measurement of protein conentration and then mixed with Freund adjuvant. This antigen fluid was first injected into the plantae of the model group rats, and then into their plantae, dorsa, inguina and abdominal cavities (no Freund adjuvant for the last injection) again on the 10th, 17th, 24th and 31st day. When a certain titer of serum anti colonic antibody was reached, 2% formalin and antigen fluid (no Freund adjuvant) were administered separately by enema. The ulcerative colitis rat model was thus set up. The animals were randomly divided into four groups: model control group (MC, n =8), electro acupuncture group (EA, n =8), herbs partition moxibustion group (HPM 8), normal control group (NC, n =8). HPM: Moxa cones made of refined mugwort floss were placed on the medicinal pad (medicinal pad dispensing: Radix Aconiti praeparata, cortex Cinnamomi, etc ) for Qihai (RN 6) and Tianshu (ST 25, bilateral) and ignited. Two moxa cones were used for each acupoint once a day and 14 times in all. EA: Tianshu (bilateral) and Qihai were stimulated by the intermittent pulse with 2Hz frequency, 4mA intensity for 20 minutes once a day and 14 times in all. After treatment, rats of all four groups were killed simultaneously. The spleen was separated and the distal colon was dissected. Total tissue RNA was isolated by the guanidinium thiocyanate phenol chloroform extraction method. RT PCR technique was used to study the expression of IL 1β and IL 6 mRNA. RESULTS IL 1β and IL 6 mRNAs were not detected in the spleen and colonic mucosa of the NC rats, whereas they were significantly expressed in that of the MC rats. IL 1β and IL 6 mRNAs were markedly lower in the EA and HPM rats than that in MC rats. There was no significant difference between the levels of IL 1β and IL 6 mRNAs in the EA and HPM rats. The expressions of IL 1β and IL 6 mRNAs were nearly the same in the spleen and colon of all groups. CONCLUSION Acupuncture and moxibustion greatly inhibited the expression of IL 1β and IL 6 mRNA in the experimental ulcerative colitis rats.Wu HG Zhou LB Pan YY Huang C Chen HP Shi Z Hua XG 1999World Journal of Gastroenterology1999,5,6:45
10Spatial Distribution of Heavy Metals in Agricultural Soils of an Industry-Based Peri-Urban Area in Wuxi, China显示文摘In industry-oriented peri-urban areas, the heavy metal accumulation in soils caused by industrialization has become a potential threat. The top soil samples from 27 paddy fields and 75 vegetable fields were collected from a typical industry-based peri-urban area of about 8 km2 in Wuxi, China, to study the accumulation and distribution of As, Hg, Cu, Zn, Pb, Cr, and Cd in comparison with heavy metal contents in soils near developed industrial sites (Guangzhou, China; Wallsend Burn of Tyneside, UK; and Osnabriick, Germany). Kriging interpolation was used to determine the metals' spatial distribution. The results showed that most soils, compared to the background values, contained elevated contents of As, Hg, Cu, Zn, and Pb with some having elevated contents of Cd and Cr. Except for less than 10% of the soil samples of Cu, Zn and Cd contents, these heavy metal contents were lower than the soil threshold levels of the Grade II criteria for the Chinese environmental quality standard. Probably, because of the scattered distribution and diversity of industries in the study area, spatial distributions of these heavy metals from Kriging interpolation indicated little similarity. Nevertheless, when compared with other areas in the Taihu Lake region, mean contents of Cu, Zn, Pb, and Cd were relatively high in the Wuxi peri-urban area. Additionally, compared to soils in agricultural areas around Guangzhou, Osnabriick, or Wallsend Burn, contents of most heavy metals in soils from this area were lower.ZHAO Yan-Feng SHI Xue-Zheng HUANG Biao YU Dong-Sheng WANG Hong-Jie SUN Wei-Xia I.

12Electroacupuncture improves learning and memory functions in a rat cerebral ischemia/reperfusion injury model through PI3K/Akt signaling pathway activation显示文摘Electroacupuncture has been widely used to treat cognitive impairment after cerebral ischemia,but the underlying mechanism has not yet been fully elucidated.Studies have shown that autophagy plays an important role in the formation and development of cognitive impairment,and the phosphoinositide 3-kinase(PI3K)/Akt signaling pathway plays an important role in autophagy regulation.To investigate the role played by the PI3K/Akt signaling pathway in the electroacupuncture treatment of cerebral ischemia/reperfusion rat models,we first established a rat model of cerebral ischemia/reperfusion through the occlusion of the middle cerebral artery using the suture method.Starting at 2 hours after modeling,electroacupuncture was delivered at the Shenting(GV24)and Baihui(GV20)acupoints,with a dilatational wave(1-20 Hz frequency,2 mA intensity,6 V peak voltage),for 30 minutes/day over 8 consecutive days.Our results showed that electroacupuncture reduced the infarct volume in a rat model of cerebral ischemia/reperfusion injury,increased the mRNA expression levels of the PI3K/Akt signaling pathwayrelated factors Beclin-1,mammalian target of rapamycin(mTOR),and PI3K,increased the protein expression levels of phosphorylated Akt,Beclin-1,PI3K,and mTOR in the ischemic cerebral cortex,and simultaneously reduced p53 mRNA and protein expression levels.In the Morris water maze test,the latency to find the hidden platform was significantly shortened among rats subjected to electroacupuncture stimulation compared with rats without electroacupuncture stimulation.In the spatial probe test,the number of times that a rat crossed the target quadrant was increased in rats subjected to electroacupuncture stimulation compared with rats without electroacupuncture stimulation.Electroacupuncture stimulation applied to the Shenting(GV24)and Baihui(GV20)acupoints activated the PI3K/Akt signaling pathway and improved rat learning and memory impairment.This study was approved by the Animal Ethics Committee of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine,China(approval No.8150150901)on March 10,2016.Hui-Ling Wang Fei-Lai Liu Rui-Qing Li Ming-Yue Wan Jie-Ying Li Jing Shi Ming-Li Wu Jun-Hua Chen Wei-Juan Sun Hong-Xia Feng Wei Zhao Jin Huang Ren-Chao Liu Wen-Xue Hao Xiao-Dong Feng 2021Neural Regeneration Research2021,16,6:48
13Epidemiology and risk factors of colorectal cancer in China显示文摘In China, colorectal cancer(CRC) ranked fourth and fifth in the highest incidence and mortality rates of all malignancies in 2018, respectively. Although these rates are below the world average, China placed first worldwide in the number of new CRC cases and CRC-related deaths because of its comparatively large population. This disease represents a threat to the health of population and incurs a heavy economic burden on the society and individuals. CRC has various risk factors, including age, sex, lifestyle, genetic factors, obesity, diabetes, gut microbiota status, and precancerous lesions. Furthermore, incidence and mortality rates of CRC are closely related to socioeconomic development levels, varying according to regional and population characteristics. Prevention is the main strategy to reduce incidence and mortality rates of CRC. This can be achieved through strategies stimulating lifestyle changes, healthy diet habits, and early screening for high-risk individuals. To reduce the burden of CRC, public health officials should promote prevention and management of modifiable risk factors through national policies. The rising incidence and mortality rates of CRC in China may be timely curbed by clarifying specific epidemiological characteristics, optimizing early screening strategies, and strictly implementing diagnosis and treatment guidelines. Thus, this study aimed to collect and report the current research status on epidemiology and risk factors of CRC in China.Yong Yang Zihan Han Xin Li An Huang Jingyi Shi Jin Gu 2020Chinese Journal of Cancer Research2020,32,6:42
14An analysis of the spatial and temporal changes in Chinese terrestrial ecosystem service functions显示文摘Since Westman(1977) and Ehrlich(1982) put forward the concepts of 'the service of nature' and 'ecosystem service functions',respectively,methods for conducting value accounting for them,and their practical application have become the subjects of intense study.Based on an overview of available research findings,we discuss three scientific hypotheses.First,the terrestrial ecosystem offers both positive and negative service functions.Second,changes in terrestrial ecosystem service functions lie not only in the number of ecosystem types and the coverage area of each type,but also in their quality.Third,the value of terrestrial ecosystem service functions should be assessed both in terms of the value stocked and the value added.We collected land use data from China during the period 1999-2008,and Normalized Difference Vegetation Index data based on remote sensing images from the Global Inventory Modeling and Mapping Studies for the same period.We then calculated and analyzed spatial and temporal changes in China's terrestrial ecosystem service values over the 10-year period.Considering temporal change,the total value(stocked) of China's terrestrial ecosystem service functions decreased from 6.82 trillion Yuan RMB in 1999 to 6.57 trillion Yuan RMB in 2008.During that period,the positive value decreased by 240.17 billion Yuan RMB and the negative value increased by 8.85 billion Yuan RMB.The decrease in total value lies mainly in the humidity control,soil formation,and waste recycling functions.The total value(added) of China's terrestrial ecosystem service functions increased by 4.31 billion Yuan RMB in 2000,but decreased by 0.13 billion Yuan RMB in 2008(based on the constant price of China in 1999).The value(added) was a negative figure.From the perspective of spatial change,we can see that the supply of China's terrestrial ecosystem service functions fell slightly over the past 10 years,mainly in Northeast and Southern China.As a result of human activities on ecosystems,the loss of ecosystem service functions' value was relatively prominent in Shanxi and Gansu provinces,compared with an increase in value in Shaanxi Province.Terrestrial ecosystem service functions' value per unit area was relatively high in mid-and East China,showing a prominent spatial change over the 10-year period,but low in Western China.Some conclusions are drawn after an in-depth analysis of the factors causing the spatial and temporal changes in China's terrestrial ecosystem service functions,in the hope that our suggestions will be helpful for the management of China's terrestrial ecosystems.SHI Yao WANG RuSong HUANG JinLou YANG WenRui 2012Chinese Science Bulletin2012,57,17:39
15Solid state fermentation of rapeseed cake with Aspergillus niger for degrading glucosinolates and upgrading nutritional value显示文摘Background:Rapeseed cake is a good source of protein for animal feed but its utilization is limited due to the presence of anti-nutritional substances,such as glucosinolates(GIs),phytic acid,tannins etc.In the present study,a solid state fermentation(SSF) using Aspergillus niger was carried out with the purpose of degrading glucosinolates and improving the nutritional quality of rapeseed cake(RSC).The effects of medium composition and incubation conditions on the GIs content in fermented rapeseed cake(FRSC) were investigated,and chemical composition and amino acid in vitro digestibility of RSC substrate fermented under optimal conditions were determined.Results:After 72 h of incubation at 34℃,a 76.89%decrease in GIs of RSC was obtained in solid medium containing 70%RSC,30%wheat bran at optimal moisture content 60%(w/w).Compared to unfermented RSC,trichloroacetic acid soluble protein(TCA-SP),crude protein and ether extract contents of the FRSC were increased(P< 0.05) 103.71,23.02 and 23.54%,respectively.As expected,the contents of NDF and phytic acid declined(P< 0.05) by 9.12 and 44.60%,respectively.Total amino acids(TAA) and essential amino acids(EAA) contents as well as AA in vitro digestibility of FRSC were improved significantly(P< 0.05).Moreover,the enzyme activity of endoglucanase,xylanase,acid protease and phytase were increased(P<0.05) during SSF.Conclusions:Our results indicate that the solid state fermentation offers an effective approach to improving the quality of proteins sources such as rapeseed cake.Changyou Shi Jun He Jie Yu Bing Yu Zhiqing Huang Xiangbing Mao Ping Zheng Daiwen Chen 2015Journal of Animal Science and Biotechnology2015,6,3:32

17Modulatory effects of acupuncture on brain networks in mild cognitive impairment patients显示文摘Functional magnetic resonance imaging has been widely used to investigate the effects of acupuncture on neural activity. However, most functional magnetic resonance imaging studies have focused on acute changes in brain activation induced by acupuncture. Thus, the time course of the therapeutic effects of acupuncture remains unclear. In this study, 32 patients with amnestic mild cognitive impairment were randomly divided into two groups, where they received either Tiaoshen Yizhi acupuncture or sham acupoint acupuncture. The needles were either twirled at Tiaoshen Yizhi acupoints, including Sishencong(EX-HN1), Yintang(EX-HN3), Neiguan(PC6), Taixi(KI3), Fenglong(ST40), and Taichong(LR3), or at related sham acupoints at a depth of approximately 15 mm, an angle of ± 60°, and a rate of approximately 120 times per minute. Acupuncture was conducted for 4 consecutive weeks, five times per week, on weekdays. Resting-state functional magnetic resonance imaging indicated that connections between cognition-related regions such as the insula, dorsolateral prefrontal cortex, hippocampus, thalamus, inferior parietal lobule, and anterior cingulate cortex increased after acupuncture at Tiaoshen Yizhi acupoints. The insula, dorsolateral prefrontal cortex, and hippocampus acted as central brain hubs. Patients in the Tiaoshen Yizhi group exhibited improved cognitive performance after acupuncture. In the sham acupoint acupuncture group, connections between brain regions were dispersed, and we found no differences in cognitive function following the treatment. These results indicate that acupuncture at Tiaoshen Yizhi acupoints can regulate brain networks by increasing connectivity between cognition-related regions, thereby improving cognitive function in patients with mild cognitive impairment.Ting-ting Tan Dan Wang Ju-ke Huang Xiao-mei Zhou Xu Yuan Jiu-ping Liang Liang Yin Hong-liang Xie Xin-yan Jia Jiao Shi Fang Wang Hao-bo Yang Shang-jie Chen 2017Neural Regeneration Research2017,12,2:32
18Artesunate synergizes with sorafenib to induce ferroptosis in hepatocellular carcinoma显示文摘Sorafenib is the first-line medication for advanced hepatocellular carcinoma(HCC),but it can only extend limited survival.It is imperative to find a combination strategy to increase sorafenib efficacy.Artesunate is such a preferred candidate,because artesunate is clinically well-tolerated and more importantly both drugs can induce ferroptosis through different mechanisms.In this study we investigated the combined effect of sorafenib and artesunate in inducing ferroptosis of HCC and elucidated the involved molecular mechanisms.We showed that artesunate greatly enhanced the anticancer effects of low dose of sorafenib against Huh7,SNU-449,and SNU-182 HCC cell lines in vitro and against Huh7 cell xenograft model in Balb/c nude mice.The combination index method confirmed that the combined effect of sorafenib and artesunate was synergistic.Compared with the treatment with artesunate or sorafenib alone,combined treatment induced significantly exacerbated lipid peroxidation and ferroptosis,which was blocked by N-acetyl cysteine and ferroptosis inhibitors liproxstatin-1 and deferoxamine mesylate,but not by inhibitors of other types of cell death(z-VAD,necrostatin-1 and belnacasan).In Huh7 cells,we demonstrated that the combined treatment induced oxidative stress and lysosome-mediated ferritinophagy,two essential aspects of ferroptosis.Sorafenib at low dose mainly caused oxidative stress through mitochondrial impairments and SLC7A11-invovled glutathione depletion.Artesunate-induced lysosome activation synergized with sorafenib-mediated pro-oxidative effects by promoting sequential reactions including lysosomal cathepsin B/L activation,ferritin degradation,lipid peroxidation,and consequent ferroptosis.Taken together,artesunate could be repurposed to sensitize sorafenib in HCC treatment.The combined treatment can be easily translated into clinical applications.Zhong-jie Li Hui-qi Dai Xiao-wei Huang Ji Feng Jing-huan Deng Zi-xuan Wang Xiao-mei Yang Yu-jia Liu Yong Wu Pan-hong Chen Huan Shi Ji-gang Wang Jing Zhou Guo-dong Lu 2021Acta Pharmacologica Sinica2021,42,2:31
19Terrestrial carbon sinks in China and around the world and their contribution to carbon neutrality显示文摘Enhancing the terrestrial ecosystem carbon sink(referred to as terrestrial C sink) is an important way to slow down the continuous increase in atmospheric carbon dioxide(CO_(2)) concentration and to achieve carbon neutrality target.To better understand the characteristics of terrestrial C sinks and their contribution to carbon neutrality,this review summarizes major progress in terrestrial C budget researches during the past decades,clarifies spatial patterns and drivers of terrestrial C sources and sinks in China and around the world,and examines the role of terrestrial C sinks in achieving carbon neutrality target.According to recent studies,the global terrestrial C sink has been increasing from a source of (-0.2±0.9) Pg C yr^(-1)(1 Pg=1015g)in the 1960s to a sink of (1.9±1.1) Pg C yr^(-1) in the 2010s.By synthesizing the published data,we estimate terrestrial C sink of 0.20–0.25 Pg C yr^(-1) in China during the past decades,and predict it to be 0.15–0.52 Pg C yr^(-1) by 2060.The terrestrial C sinks are mainly located in the mid-and high latitudes of the Northern Hemisphere,while tropical regions act as a weak C sink or source.The C balance differs much among ecosystem types:forest is the major C sink;shrubland,wetland and farmland soil act as C sinks;and whether the grassland functions as C sink or source remains unclear.Desert might be a C sink,but the magnitude and the associated mechanisms are still controversial.Elevated atmospheric CO_(2) concentration,nitrogen deposition,climate change,and land cover change are the main drivers of terrestrial C sinks,while other factors such as fires and aerosols would also affect ecosystem C balance.The driving factors of terrestrial C sink differ among regions.Elevated CO_(2) concentration and climate change are major drivers of the C sinks in North America and Europe,while afforestation and ecological restoration are additionally important forcing factors of terrestrial C sinks in China.For future studies,we recommend the necessity for intensive and long-term ecosystem C monitoring over broad geographic scale to improve terrestrial biosphere models for accurately evaluating terrestrial C budget and its dynamics under various climate change and policy scenarios.Yuanhe Yang Yue Shi Wenjuan Sun Jinfeng Chang Jianxiao Zhu Leiyi Chen Xin Wang Yanpei Guo Hongtu Zhang Lingfei Yu Shuqing Zhao Kang Xu Jiangling Zhu Haihua Shen Yuanyuan Wang Yunfeng Peng Xia Zhao Xiangping Wang Huifeng Hu Shiping Chen Mei Huang Xuefa Wen Shaopeng Wang Biao Zhu Shuli Niu Zhiyao Tang Lingli Liu Jingyun Fang 2022Science China(Life Sciences)2022,65,5:32
20Sorafenib in treatment of patients with advanced hepatocellular carcinoma:a systematic review显示文摘BACKGROUND: Sorafenib has become the standard first-line treatment for patients with advanced hepatocellular carcinoma (HCC). This study aimed to assess the efficacy and safety of sorafenib in advanced HCC patients and explore its true value for specific subgroups. DATA SOURCES: A computer-based systematic search from January 2005 to June 2011 with 'sorafenib' and 'advanced hepatocellular carcinoma' as search terms was performed for possible clinical trials. Hazard ratios (HR) and their 95% confidence intervals (CI) for overall survival (OS) and time to progression (TTP), rates of partial response (PR), rates of toxicity effects, and details of subgroup analysis were extracted. Meta-analyses were done using the software Review Manager (version 5.0). RESULTS: Six trials with 1164 patients were included. Based on three randomized controlled trials, the pooled HR (sorafenib/ placebo) was 0.66 for OS (95% CI: 0.56-0.78; P<0.00001) and 0.57 for TTP (95% CI: 0.47-0.68; P<0.00001). The pooled odds ratio (OR) for PR was 2.96 (95% CI: 0.96-9.15; P=0.06). For three single-arm trials, the pooled HR was 0.69 for OS (95% CI: 0.56-0.84; P=0.0002) and 0.64 for TTP (95% CI: 0.52-0.78; P<0.00001). The pooled OR for PR in three single-arm trials was 3.56 (95% CI: 1.22-10.39; P=0.02). Subgroup analysis indicated that sorafenib was less effective in patients with extrahepatic spread (with: P=0.13 vs without: P<0.0001), with normal alpha-fetoprotein level (AFP) (P=0.15 vs elevated: P=0.0006), and with elevated level of serum bilirubin (P=0.06 vs normal: P=0.0009). Sorafenib-based therapy significantly increased the risk of grade 3/4 hand-foot skin reaction, diarrhea, fatigue, and rash/desquamation.CONCLUSIONS: Sorafenib-based therapy benefits advanced HCC patients. Meanwhile, sorafenib is less effective for patients with extrahepatic spread, with normal AFP level and with elevated level of bilirubin.Xin Zhang, Xin-Rong Yang, Xiao-Wu Huang, Wei-Min Wang, Ruo-Yu Shi, Yang Xu, Zheng Wang, Shuang-Jian Qiu, Jia Fan ,Jian Zhou Liver Cancer Institute, Zhongshan Hospital, Fudan University, Shanghai Key Laboratory for Organ Transplantation, Shanghai 200032, China,Institute of Biomedical Sciences, Fudan University, Shanghai 200032, China 2012Hepatobiliary & Pancreatic Diseases International2012,11,5:29
