| 1 | Multimodality treatment in hepatocellular carcinoma patients with tumor thrombi in portal vein显示文摘AIM To compare the therapeutic effect andsignificances of multimodality treatment forhepatocellular carcinoma (HCC) with tumorthrombi in portal vein (PVTT).METHODS HCC patients (n = 147) with tumortrombi in the main portal vein or the first branchof portal vein were divided into four groups bythe several therapeutic methods. There wereconservative treatment group in 18 out ofpatients (group A); and hepatic artery ligation(HAL) and/or hepatic artery infusion (HAl)group in 18 patients (group B), in whompostoberative chemoembolization was doneperiodically; group of removal of HCC with PVTTin 79 (group C) and group of transcatheterhepatic arterial chemoembolization (TACE) orHAl and/or portal vein infusion (PVI) afteroperation in 32 (group D).RESULTS The median survival period was 12months in our series and the 1-, 3-, and 5-yearsurvival rates were 44.3%, 24.5% and 15.2%,respectively. The median survival times were 2,5, 12 and 16 months in group A, B, C and D,respectively. The 1-, 3- and 5-year survival rateswere 5.6%, 0% and 0% in group A; 22.2%,5.6% and 0% in group B; 53.9%, 26.9% and16.6% in group C; 79.3%, 38.9% and 26.8% ingroup D, respectively. Significant differenceappeared in the survival rates among the groups(P<0.05).CONCLUSION Hepatic resection with removalof tumor thrombi and HCC should increase thecurative effects and be encouraged for theprolongation of life span and quality of life forHCC patients with PVTT, whereas the besttherapeutic method for HCC with PVTT is withregional hepatic chemotherapy orchemoemblization after hepatic resection withremoval of tumor thrombi. | Jia Fan Zhi Quan Wu Zhao You Tang Jian Zhou Shuang Jian Qiu Zeng Chen Ma Xin Da Zhou Sheng Long Ye Liver Cancer Institute, Zhongshan Hospital, Fudan University Medical Center (Former Shanghai University), 136 Yixueyuan Road, Shanghai 200032, China | 2001 | World Journal of Gastroenterology2001，7，1： | 80 |

| 3 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014，27，5： | 17 |
| 4 | Influence of high energy ball milling on Al-30Si powder and ceramic particulate显示文摘The influence of high energy ball milling on Al 30Si powder and ceramic particulate SiC was studied by means of SEM, XRD and DSC. The results show that Al 30Si powder and their microstructure are obviously refined after high energy ball milling process. The alloy powder and SiC p stick closely to each other without interfacial reaction. DSC results detect no reaction but relaxation of the samples. So high energy ball milling can be used as an effective method for ceramic particulate pre treatment in the fabrication of MMC. | LI Yuan yuan(李元元) ZHANG Da tong(张大童) XIAO Zhi yu(肖志宇) | 2000 | 中国有色金属学会会刊:英文版2000，10，3： | 12 |

| 10 | Room temperature ferromagnetism in ultra-thin van der Waals crystals of 1T-CrTe2显示文摘Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications. | Xingdan Sun Wanying Li Xiao Wang Qi Sui Tongyao Zhang Zhi Wang Long Liu Da Li Shun Feng Siyu Zhong Hanwen Wang Vincent Bouchiat Manuel Nunez Regueiro Nicolas Rougemaille Johann Coraux Anike Purbawati Abdellali Hadj-Azzem Zhenhua Wang Baojuan Dong Xing Wu Teng Yang Guoqiang Yu Bingwu Wang Zheng Han Xiufeng Han Zhidong Zhang | 2020 | Nano Research2020，13，12： | 6 |
