| 1 | Dynamic phenotypic heterogeneity and the evolution of multiple RNA subtypes in hepatocellular carcinoma:the PLANET study显示文摘Intra-tumor heterogeneity(ITH) is a key challenge in cancer treatment, but previous studies have focused mainly on the genomic alterations without exploring phenotypic(transcriptomic and immune)heterogeneity. Using one of the largest prospective surgical cohorts for hepatocellular carcinoma(HCC)with multi-region sampling, we sequenced whole genomes and paired transcriptomes from 67 HCC patients(331 samples). We found that while genomic ITH was rather constant across stages, phenotypic ITH had a very different trajectory and quickly diversified in stage Ⅱ patients. Most strikingly, 30% of patients were found to contain more than one transcriptomic subtype within a single tumor. Such phenotypic ITH was found to be much more informative in predicting patient survival than genomic ITH and explains the poor efficacy of single-target systemic therapies in HCC. Taken together, we not only revealed an unprecedentedly dynamic landscape of phenotypic heterogeneity in HCC, but also highlighted the importance of studying phenotypic evolution across cancer types. | Weiwei Zhai Hannah Lai Neslihan Arife Kaya Jianbin Chen Hechuan Yang Bingxin Lu Jia Qi Lim Siming Ma Sin Chi Chew Khi Pin Chua Jacob Josiah Santiago Alvarez Pauline Jieqi Chen Mei Mei Chang Lingyan Wu Brian K.P.Goh Alexander Yaw-Fui Chung Chung Yip Chan Peng Chung Cheow Ser Yee Lee Juinn Huar Kam Alfred Wei-Chieh Kow Iyer Shridhar Ganpathi Rawisak Chanwat Jidapa Thammasiri Boon Koon Yoong Diana Bee-Lan Ong Vanessa H.de Villa Rouchelle D.Dela Cruz Tracy Jiezhen Loh Wei Keat Wan Zeng Zeng Anders Jacobsen Skanderup Yin Huei Pang Krishnakumar Madhavan Tony Kiat-Hon Lim Glenn Bonney Wei Qiang Leow Valerie Chew Yock Young Dan Wai Leong Tam Han Chong Toh Roger Sik-Yin Foo Pierce Kah-Hoe Chow | 2022 | National Science Review2022，9，3： | 1 |
| 3 | National incidence of joint dislocation in China:a retrospective survey of 512,187 individuals显示文摘Background:Joint dislocations significantly impact public health.However,a comprehensive study on the incidence,distribution,and risk factors for joint dislocations in China is lacking.We conducted the China National Joint Dislocation Study,which is a part of the China National Fracture Study conducted to obtain the national incidence and risk factors for traumatic fractures,and to investigate the incidence and risk factors for joint dislocations.Methods:For this national retrospective epidemiological study,512,187 participants were recruited using stratified random sampling and probability-proportional-to-size method from January 19 to May 16,2015.Participants who sustained joint dislocations of the trunk,arms,or legs(skull,sternum,and ribs being excluded)in 2014 were personally interviewed to obtain data on age,educational background,ethnic origin,occupation,geographic region,and urbanization degree.The joint-dislocation incidence was calculated based on age,sex,body site,and demographic factors.The risk factors for different groups were examined using multiple logistic regression.Results:One hundred and nineteen participants sustained 121 joint dislocations in 2014.The population-weighted incidence rate of joint dislocations of the trunk,arms,or legs was 0.22(95%confidence interval[CI]:0.16,0.27)per 1000 population in 2014(men,0.27[0.20,0.34];women,0.16[0.10,0.23]).For all ages,previous dislocation history(male:OR 42.33,95%confidence interval[CI]:12.03-148.90;female:OR 54.43,95%CI:17.37-170.50)and alcohol consumption(male:OR 3.50,95%CI:1.49-8.22;female:OR 2.65,95%CI:1.08-6.50)were risk factors for joint dislocation.Sleeping less than 7 h/day was a risk factor for men.Compared with children,women aged≥15 years(female 15-64 years:OR 0.16,95%CI:0.04-0.61;female≥65 years:OR 0.06,95%CI:0.01-0.41)were less likely to sustain joint dislocations.Women with more than three children were at higher dislocation risk than women without children(OR 6.92,95%CI:1.18-40.78).Conclusions:The up-to-date data on joint dislocation incidence,distribution,and risk factors can be used as a reference for national healthcare,prevention,and management in China.Specific strategies for decreasing alcohol consumption and encouraging adequate sleeping hours should be developed to prevent or reduce dislocation incidents.Trial Registration:Chinese Clinical Trial Registry,ChiCTR-EPR-15005878. | Hongzhi Lv Wei Chen Zhiyong Hou Siming Jia Yanbin Zhu Bo Liu Xiao Chen Guang Yang Lei Liu Tao Zhang Haili Wang Bing Yin Song Liu Jialiang Guo Xiaolin Zhang Yichong Li Yingze Zhang | 2022 | Chinese Medical Journal2022，，14： | 0 |
