1Ridge subduction and porphyry copper-gold mineralization:An overview显示文摘Many large porphyry Cu-Au deposits are connected to adakitic rocks known to be closely associated with ridge subduction. For example, there are several subducting ridges along the east Pacific margin, e.g., in Chile, Peru, and South America, most of which are associated with large porphyry Cu-Au deposits. In contrast, there are much fewer ridge subductions on the west Pacific margin and porphyry Cu-Au deposits are much less there, both in terms of tonnage and the number of deposits. Given that Cu and Au are moderately incompatible elements, oceanic crust has much higher Cu-Au concentrations than the mantle and the continental crust, and thus slab melts with their diagnostic adakitic chemistry have systematically higher Cu and Au, which is favorable for mineralization. Considering the geotherm of subducting slabs in the Phanerozoic, ridge subduction is the most favorable tectonic setting for this. Therefore, slab melting is the likely link in the spatial association between ridge subduction and Cu-Au deposits. Geochemical signatures of slab melting and hence maybe ridge subduction in less eroded regions in eastern China, the central Asian orogenic belt etc. may indicate important exploration targets for large porphyry Cu-Au deposits.SUN WeiDong LING MingXing YANG XiaoYong FAN WeiMing DING Xing LIANG HuaYing 2010Science China Earth Sciences2010,53,4:97
2Mechanism for the formation of the January 2013 heavy haze pollution episode over central and eastern China显示文摘In January 2013,a long-lasting episode of severe haze occurred in central and eastern China,and it attracted attention from all sectors of society.The process and evolution of haze pollution episodes were observed by the'Forming Mechanism and Control Strategies of Haze in China'group using an intensive aerosol and trace gases campaign that simultaneously obtained data at 11 ground-based observing sites in the CARE-China network.The characteristics and formation mechanism of haze pollution episodes were discussed.Five haze pollution episodes were identified in the Beijing-Tianjin-Hebei(Jing-Jin-Ji)area;the two most severe episodes occurred during 9–15 January and 25–31 January.During these two haze pollution episodes,the maximum hourly PM2.5mass concentrations in Beijing were 680 and 530μg m 3,respectively.The process and evolution of haze pollution episodes in other major cities in the Jing-Jin-Ji area,such as Shijiazhuang and Tianjin were almost the same as those observed in Beijing.The external cause of the severe haze episodes was the unusual atmospheric circulation,the depression of strong cold air activities and the very unfavorable dispersion due to geographical and meteorological conditions.However,the internal cause was the quick secondary transformation of primary gaseous pollutants to secondary aerosols,which contributed to the'explosive growth'and'sustained growth'of PM2.5.Particularly,the abnormally high amount of nitric oxide(NOx)in the haze episodes,produced by fossil fuel combustion and vehicle emissions,played a direct or indirect role in the quick secondary transformation of coal-burning sulphur dioxide(SO2)to sulphate aerosols.Furthermore,gaseous pollutants were transformed into secondary aerosols through heterogeneous reactions on the surface of fine particles,which can change the particle’s size and chemical composition.Consequently,the proportion of secondary inorganic ions,such as sulphate and nitrate,gradually increased,which enhances particle hygroscopicity and thereby accelerating formation of the haze pollution.WANG YueSi YAO Li WANG LiLi LIU ZiRui JI DongSheng TANG GuiQian ZHANG JunKe SUN Yang HU Bo XIN JinYuan 2014Science China Earth Sciences2014,57,1:189
3Liver cancer incidence and mortality in China: Temporal trends and projections to 2030显示文摘Objective: Liver cancer is one of the most common cancers and major cause of cancer deaths in China,which accounts for over 50% of new cases and deaths worldwide.The systematic liver cancer statistics including of projection through 2030 could provide valuable information for prevention and control strategies in China,and experience for other countries.Methods: The burden of liver cancer in China in 2014 was estimated using 339 cancer registries' data selected from Chinese National Cancer Center(NCC).Incident cases of 22 cancer registries were applied for temporal trends from 2000 to 2014.The burden of liver cancer through 2030 was projected using age-period-cohort model.Results: About 364,800 new cases of liver cancer(268,900 males and 95,900 females) occurred in China,and about 318,800 liver cancer deaths(233,500 males and 85,300 females) in 2014.Western regions of China had the highest incidence and mortality rates.Incidence and mortality rates decreased by about 2.3% and 2.6% per year during the period of 2000-2014,respectively,and would decrease by more than 44% between 2014 and 2030 in China.The young generation,particularly for those aged under 40 years,showed a faster down trend.Conclusions: Based on the analysis,incidence and mortality rates of liver cancer are expected to decrease through 2030,but the burden of liver cancer is still serious in China,especially in rural and western areas.Most cases of liver cancer in China can be prevented through vaccination and more prevention efforts should be focused on high risk groups.Rongshou Zheng Chunfeng Qu Siwei Zhang Hongmei Zeng Kexin Sun Xiuying Gu Changfa Xia Zhixun Yang He Li Wenqiang Wei Wanqing Chen Jie He 2018Chinese Journal of Cancer Research2018,30,6:132

7Cancer incidence and mortality in China, 2014显示文摘Background: National Central Cancer Registry of China(NCCRC) updated nationwide cancer statistics using population-based cancer registry data in 2014 collected from all available cancer registries.Methods: In 2017, 449 cancer registries submitted cancer registry data in 2014, among which 339 registries' data met the criteria of quality control and were included in analysis. These cancer registries covered 288,243,347 population, accounting for about 21.07% of the national population in 2014. Numbers of nationwide new cancer cases and deaths were estimated using calculated incidence and mortality rates and corresponding national population stratified by area, sex, age group and cancer type. The world Segi's population was applied for agestandardized rates.Results: A total of 3,804,000 new cancer cases were diagnosed, the crude incidence rate was 278.07/100,000(301.67/100,000 in males, 253.29/100,000 in females) and the age-standardized incidence rate by world standard population(ASIRW) was 186.53/100,000. Calculated age-standardized incidence rate was higher in urban areas than in rural areas(191.6/100,000 vs. 179.2/100,000). South China had the highest cancer incidence rate while Southwest China had the lowest incidence rate. Cancer incidence rate was higher in female for population between20 to 54 years but was higher in male for population younger than 20 years or over 54 years. A total of 2,296,000 cancer deaths were reported, the crude mortality rate was 167.89/100,000(207.24/100,000 in males,126.54/100,000 in females) and the age-standardized mortality rate by world standard population(ASMRW) was106.09/100,000. Calculated age-standardized mortality rate was higher in rural areas than in urban areas(110.3/100,000 vs. 102.5/100,000). East China had the highest cancer mortality rate while North China had the lowest mortality rate. The mortality rate in male was higher than that in female. Common cancer types and major causes of cancer death differed between age group and sex.Conclusions: Heavy cancer burden and its disparities between area, sex and age group pose a major challenge to public health in China. Nationwide cancer registry plays a crucial role in cancer prevention and control.Wanqing Chen Kexin Sun Rongshou Zheng Hongmei Zeng Siwei Zhang Changfa Xia Zhixun Yang He Li Xiaonong Zou Jie He 2018Chinese Journal of Cancer Research2018,30,1:832
8Sodium oligomannate therapeutically remodels gut microbiota and suppresses gut bacterial amino acids-shaped neuroinflammation to inhibit Alzheimer's disease progression显示文摘Recently,increasing evidence has suggested the association between gut dysbiosis and Alzheimer's disease(AD)progression,yet the role of gut microbiota in AD pathogenesis remains obscure.Herein,we provide a potential mechanistic link between gut microbiota dysbiosis and neuroinflammation in AD progression.Using AD mouse models,we discovered that,during AD progression,the alteration of gut microbiota composition leads to the peripheral accumulation of phenylalanine and isoleucine,which stimulates the differentiation and proliferation of pro-inflammatory T helper 1(Thl)cells.The brain-infiltrated peripheral Th1 immune cells are associated with the Ml microglia aaivation,contributing to AD-associated neuroinflammation.Importantly,the elevation of phenylalanine and isoleucine concentrations and the increase of Th1 cell frequency in the blood were also observed in two small independent cohorts of patients with mild cognitive impairment(MCI)due to AD.Furthermore,GV-971,a sodium oligomannate that has demonstrated solid and consistent cognition improvement in a phase 3 clinical trial in China,suppresses gut dysbiosis and the associated phenylalanine/isoleucine accumulation,harnesses neuroinflammation and reverses the cognition impairment.Together,our findings highlight the role of gut dysbiosis-promoted neuroinflammation in AD progression and suggest a novel strategy for AD therapy by remodelling the gut microbiota.Xinyi Wang Guangqiang Sun Teng Feng Jing Zhang Xun Huang Tao Wang Zuoquan Xie Xingkun Chu Jun Yang Huan Wang Shuaishuai Chang Yanxue Gong Lingfei Ruan Guanqun Zhang Siyuan Yan Wen Lian Chen Du Dabing Yang Qingli Zhang Feifei Lin Jia Liu Haiyan Zhang Changrong Ge Shifu Xiao Jian Ding Meiyu Geng 2019Cell Research2019,29,10:192
9Future Physics Programme of BESⅢ显示文摘There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESⅢ and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BESⅢ, as well as the threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESⅢ during the remaining operation period of BEPCⅡ. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BEPCⅡ to higher luminosity.M.Ablikim M.N.Achasov P.Adlarson S.Ahmed M.Albrecht M.Alekseev A.Amoroso F.F.An Q.An Y.Bai O.Bakina R.Baldini Ferroli Y.Ban K.Begzsuren J.V.Bennett N.Berger M.Bertani D.Bettoni F.Bianchi J Biernat J.Bloms I.Boyko R.A.Briere L.Calibbi H.Cai X.Cai A.Calcaterra G.F.Cao N.Cao S.A.Cetin J.Chai J.F.Chang W.L.Chang J.Charles G.Chelkov Chen G.Chen H.S.Chen J.C.Chen M.L.Chen S.J.Chen Y.B.Chen H.Y.Cheng W.Cheng G.Cibinetto F.Cossio X.F.Cui H.L.Dai J.P.Dai X.C.Dai A.Dbeyssi D.Dedovich Z.Y.Deng A.Denig Denysenko M.Destefanis S.Descotes-Genon F.De Mori Y.Ding C.Dong J.Dong L.Y.Dong M.Y.Dong Z.L.Dou S.X.Du S.I.Eidelman J.Z.Fan J.Fang S.S.Fang Y.Fang R.Farinelli L.Fava F.Feldbauer G.Felici C.Q.Feng M.Fritsch C.D.Fu Y.Fu Q.Gao X.L.Gao Y.Gao Y.Gao Y.G.Gao Z.Gao B.Garillon I.Garzia E.M.Gersabeck A.Gilman K.Goetzen L.Gong W.X.Gong W.Gradl M.Greco L.M.Gu M.H.Gu Y.T.Gu A.Q.Guo F.K.Guo L.B.Guo R.P.Guo Y.P.Guo A.Guskov S.Han X.Q.Hao F.A.Harris K.L.He F.H.Heinsius T.Held Y.K.Heng Y.R.Hou Z.L.Hou H.M.Hu J.F.Hu T.Hu Y.Hu G.S.Huang J.S.Huang X.T.Huang X.Z.Huang Z.L.Huang N.Huesken T.Hussain W.Ikegami Andersson W.Imoehl M.Irshad Q.Ji Q.P.Ji X.B.Ji X.L.Ji H.L.Jiang X.S.Jiang X.Y.Jiang J.B.Jiao Z.Jiao D.P.Jin S.Jin Y.Jin T.Johansson N.Kalantar-Nayestanaki X.S.Kang R.Kappert M.Kavatsyuk B.C.Ke I.K.Keshk T.Khan A.Khoukaz P.Kiese R.Kiuchi R.Kliemt L.Koch O.B.Kolcu B.Kopf M.Kuemmel M.Kuessner A.Kupsc M.Kurth M.G.Kurth W.Kuhn J.S.Lange P.Larin L.Lavezzi H.Leithoff T.Lenz C.Li Cheng Li D.M.Li F.Li F.Y.Li G.Li H.B.Li H.J.Li J.C.Li J.W.Li Ke Li L.K.Li Lei Li P.L.Li P.R.Li Q.Y.Li W.D.Li W.G.Li X.H.Li X.L.Li X.N.Li X.Q.Li Z.B.Li H.Liang H.Liang Y.F.Liang Y.T.Liang G.R.Liao L.Z.Liao J.Libby C.X.Lin D.X.Lin Y.J.Lin B.Liu B.J.Liu C.X.Liu D.Liu D.Y.Liu F.H.Liu Fang Liu Feng Liu H.B.Liu H.M.Liu Huanhuan Liu Huihui Liu J.B.Liu J.Y.Liu K.Y.Liu Ke Liu Q.Liu S.B.Liu T.Liu X.Liu X.Y.Liu Y.B.Liu Z.A.Liu Zhiqing Liu Y.F.Long X.C.Lou H.J.Lu J.D.Lu J.G.Lu Y.Lu Y.P.Lu C.L.Luo M.X.Luo P.W.Luo T.Luo X.L.Luo S.Lusso X.R.Lyu F.C.Ma H.L.Ma L.L.Ma M.M.Ma Q.M.Ma X.N.Ma X.X.Ma X.Y.Ma Y.M.Ma F.E.Maas M.Maggiora S.Maldaner S.Malde Q.A.Malik A.Mangoni Y.J.Mao Z.P.Mao S.Marcello Z.X.Meng J.G.Messchendorp G.Mezzadri J.Min T.J.Min R.E.Mitchell X.H.Mo Y.J.Mo C.Morales Morales N.Yu.Muchnoi H.Muramatsu A.Mustafa S.Nakhoul Y.Nefedov F.Nerling I.B.Nikolaev Z.Ning S.Nisar S.L.Niu S.L.Olsen Q.Ouyang S.Pacetti Y.Pan M.Papenbrock P.Patteri M.Pelizaeus H.P.Peng K.Peters A.A.Petrov J.Pettersson J.L.Ping R.G.Ping A.Pitka R.Poling V.Prasad M.Qi T.Y.Qi S.Qian C.F.Qiao N.Qin X.P.Qin X.S.Qin Z.H.Qin J.F.Qiu S.Q.Qu K.H.Rashid C.F.Redmer M.Richter M.Ripka A.Rivetti V.Rodin M.Rolo G.Rong J.L.Rosner Ch.Rosner M.Rump A.Sarantsev M.Savrie K.Schoenning W.Shan X.Y.Shan M.Shao C.P.Shen P.X.Shen X.Y.Shen H.Y.Sheng X.Shi X.D Shi J.J.Song Q.Q.Song X.Y.Song S.Sosio C.Sowa S.Spataro F.F.Sui G.X.Sun J.F.Sun L.Sun S.S.Sun X.H.Sun Y.J.Sun Y.K Sun Y.Z.Sun Z.J.Sun Z.T.Sun Y.T Tan C.J.Tang G.Y.Tang X.Tang V.Thoren B.Tsednee I.Uman B.Wang B.L.Wang C.W.Wang D.Y.Wang H.H.Wang K.Wang L.L.Wang L.S.Wang M.Wang M.Z.Wang Wang Meng P.L.Wang R.M.Wang W.P.Wang X.Wang X.F.Wang X.L.Wang Y.Wang Y.F.Wang Z.Wang Z.G.Wang Z.Y.Wang Zongyuan Wang T.Weber D.H.Wei P.Weidenkaff H.W.Wen S.P.Wen U.Wiedner G.Wilkinson M.Wolke L.H.Wu L.J.Wu Z.Wu L.Xia Y.Xia S.Y.Xiao Y.J.Xiao Z.J.Xiao Y.G.Xie Y.H.Xie T.Y.Xing X.A.Xiong Q.L.Xiu G.F.Xu L.Xu Q.J.Xu W.Xu X.P.Xu F.Yan L.Yan W.B.Yan W.C.Yan Y.H.Yan H.J.Yang H.X.Yang L.Yang R.X.Yang S.L.Yang Y.H.Yang Y.X.Yang Yifan Yang Z.Q.Yang M.Ye M.H.Ye J.H.Yin Z.Y.You B.X.Yu C.X.Yu J.S.Yu C.Z.Yuan X.Q.Yuan Y.Yuan A.Yuncu A.A.Zafar Y.Zeng B.X.Zhang B.Y.Zhang C.C.Zhang D.H.Zhang H.H.Zhang H.Y.Zhang J.Zhang J.L.Zhang J.Q.Zhang J.W.Zhang J.Y.Zhang J.Z.Zhang K.Zhang L.Zhang S.F.Zhang T.J.Zhang X.Y.Zhang Y.Zhang Y.H.Zhang Y.T.Zhang Yang Zhang Yao Zhang Yi Zhang Yu Zhang Z.H.Zhang Z.P.Zhang Z.Q.Zhang Z.Y.Zhang G.Zhao J.W.Zhao J.Y.Zhao J.Z.Zhao Lei Zhao Ling Zhao M.G.Zhao Q.Zhao S.J.Zhao T.C.Zhao Y.B.Zhao Z.G.Zhao A.Zhemchugov B.Zheng J.P.Zheng Y.Zheng Y.H.Zheng B.Zhong L.Zhou L.P.Zhou Q.Zhou X.Zhou X.K.Zhou Xingyu Zhou Xiaoyu Zhou Xu Zhou A.N.Zhu J.Zhu J.Zhu K.Zhu K.J.Zhu S.H.Zhu W.J.Zhu X.L.Zhu Y.C.Zhu Y.S.Zhu Z.A.Zhu J.Zhuang B.S.Zou J.H.Zou 2020Chinese Physics C2020,44,4:517
10Cancer statistics in China and United States,2022:profiles,trends,and determinants显示文摘Background:The cancer burden in the United States of America(USA)has decreased gradually.However,China is experiencing a transition in its cancer profiles,with greater incidence of cancers that were previously more common in the USA.This study compared the latest cancer profiles,trends,and determinants between China and USA.Methods:This was a comparative study using open-source data.Cancer cases and deaths in 2022 were calculated using cancer estimates from GLOBOCAN 2020 and population estimates from the United Nations.Trends in cancer incidence and mortality rates in the USA used data from the Surveillance,Epidemiology,and End Results program and National Center for Health Statistics.Chinese data were obtained from cancer registry reports.Data from the Global Burden of Disease 2019 and a decomposition method were used to express cancer deaths as the product of four determinant factors.Results:In 2022,there will be approximately 4,820,000 and 2,370,000 new cancer cases,and 3,210,000 and 640,000 cancer deaths in China and the USA,respectively.The most common cancers are lung cancer in China and breast cancer in the USA,and lung cancer is the leading cause of cancer death in both.Age-standardized incidence and mortality rates for lung cancer and colorectal cancer in the USA have decreased significantly recently,but rates of liver cancer have increased slightly.Rates of stomach,liver,and esophageal cancer decreased gradually in China,but rates have increased for colorectal cancer in the whole population,prostate cancer in men,and other seven cancer types in women.Increases in adult population size and population aging were major determinants for incremental cancer deaths,and case-fatality rates contributed to reduced cancer deaths in both countries.Conclusions:The decreasing cancer burden in liver,stomach,and esophagus,and increasing burden in lung,colorectum,breast,and prostate,mean that cancer profiles in China and the USA are converging.Population aging is a growing determinant of incremental cancer burden.Progress in cancer prevention and care in the USA,and measures to actively respond to population aging,may help China to reduce the cancer burden.Changfa Xia Xuesi Dong He Li Maomao Cao Dianqin Sun Siyi He Fan Yang Xinxin Yan Shaoli Zhang Ni Li Wanqing Chen 2022Chinese Medical Journal2022,,5:827
11Analysis of in vivo patterns of caspase 3 gene expression in primary hepatocellular carcinoma and its relationship to p21^(WAF1) expression and hepatic apoptosis显示文摘AIM To detect the expression of caspase 3gene in primary human hepatocellular carcinoma(HCC)and investigate its relationship to p21WAF1gene expression and HCC apoptosis.METHODS In situ hybridization was employedto determine caspase 3 and p21WAF1expression inHCC.In situ end-labeling was used to detecthepatocytic apoptosis in HCC.RESULTS Twenty-one of 39(53.8%)cases ofHCC were found to express caspase 3transcripts,while 45.2% of HCC failed toexpress caspase 3.Non-cancerous adjacent livertissues showed more positive caspase 3(87.5%,7/8)as compared with HCC(P<0.05).The expression of caspase 3 is correlated withHCC differentiation,72.2%(13/18)ofmoderately to highly differentiated HCC showedcaspase 3 transcripts positive,while only 38.1%of poorly differentiated HCC harbored caspase 3transcripts(P<0.05).No relationship wasfound between caspase 3 expression and tumorsize or grade or metastasis,although 52.5%(5/8)of HCC with metastasis were caspase 3positive and a little higher than that with nometastasis(51.6%,P>0.05).Expression of caspase 3 alone did not affect the apoptosisindex(AI)of HCC.The AI was 7.12%o in caspase3-positive tumors(n=21),while in caspase 3-negative cases(n=18)6.59%0(P>0.05).Expression of caspase 3 clearly segregated withp21WAF1positive tumors as compared withp21WAF1-negative cases(16 of 23,69.6% versus5 of 16,31.3%)with statistical significance(P=0.017).In the cases with positive caspase 3and negative p21WAF1,the Al was found slightlyhigher,but with no statistical significance,thanthat with expression of p21WAF1and caspase 3(7.21‰ vs 6.98‰,P>0.05).CONCLUSION Loss of caspase 3 expressionmay contribute to HCC carcinogenesis,althoughthe expression of caspase 3 does not correlatewell with cell apoptosis in HCC.p21WAF1may bemerely one of the inhibitors which can reducecaspase 3 mediated cell apoptosis in HCCs.Bao Hua Sun Jun Zhang Bao JǜWang Xi Ping Zhao You Kun Wang Zhi Qun Yu Dong Liang Yang Lian Jie Hao Department of Clinical Immunology,Tongji Hospital,Tongji Medical University,Wuhan 430030,Hubei Province,China 2000World Journal of Gastroenterology2000,6,3:65

15Basic performance and future developments of BeiDou global navigation satellite system显示文摘The core performance elements of global navigation satellite system include availability,continuity,integrity and accuracy,all of which are particularly important for the developing BeiDou global navigation satellite system(BDS-3).This paper describes the basic performance of BDS-3 and suggests some methods to improve the positioning,navigation and timing(PNT)service.The precision of the BDS-3 post-processing orbit can reach centimeter level,the average satellite clock offset uncertainty of 18 medium circular orbit satellites is 1.55 ns and the average signal-in-space ranging error is approximately 0.474 m.The future possible improvements for the BeiDou navigation system are also discussed.It is suggested to increase the orbital inclination of the inclined geostationary orbit(IGSO)satellites to improve the PNT service in the Arctic region.The IGSO satellite can perform part of the geostationary orbit(GEO)satellite’s functions to solve the southern occlusion problem of the GEO satellite service in the northern hemisphere(namely the“south wall effect”).The space-borne inertial navigation system could be used to realize continuous orbit determination during satellite maneuver.In addition,high-accuracy space-borne hydrogen clock or cesium clock can be used to maintain the time system in the autonomous navigation mode,and stability of spatial datum.Furthermore,the ionospheric delay correction model of BDS-3 for all signals should be unified to avoid user confusion and improve positioning accuracy.Finally,to overcome the vulnerability of satellite navigation system,the comprehensive and resilient PNT infrastructures are proposed for the future seamless PNT services.Yuanxi Yang Yue Mao Bijiao Sun 2020Satellite Navigation2020,1,1:70
162018 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

18Controlled low central venous pressure reduces blood loss and transfusion requirements in hepatectomy显示文摘AIM:To evaluate the effect of low central venous pressure(LCVP)on blood loss and blood transfusion in patients undergoing hepatectomy.METHODS:Electronic databases and bibliography lists were searched for potential articles.A meta-analysis of all randomized controlled trials(RCTs)investigating LCVP in hepatectomy was performed.The following three outcomes were analyzed:blood loss,blood transfusion and duration of operation.RESULTS:Five RCTs including 283 patients were assessed.Meta-analysis showed that blood loss in the LCVP group was significantly less than that in the control group(MD=-391.95,95%CI:-559.35--224.56,P<0.00001).In addition,blood transfusion in the LCVP group was also significantly less than that in the control group(MD=-246.87,95%CI:-427.06--66.69,P=0.007).The duration of operation in the LCVP group was significantly shorter than that in the control group(MD=-18.89,95%CI:-35.18--2.59,P=0.02).Most studies found no significant difference in renal and liver function between the two groups.CONCLUSION:Controlled LCVP is a simple and effective technique to reduce blood loss and blood transfusion during liver resection,and appears to have no detrimental effects on liver and renal function.Zhi Li Yu-Ming Sun Fei-Xiang Wu Li-Qun Yang Zhi-Jie Lu Wei-Feng Yu 2014World Journal of Gastroenterology2014,20,1:60
19A Kelch Motif-Containing Serine/Threonine Protein Phosphatase Determines the Large Grain QTL Trait in Rice显示文摘A thorough understanding of the genetic basis of rice grain traits is critical for the improvement of rice (Oryza sativa L.) varieties.In this study,we generated an F 2 population by crossing the large-grain japonica cultivar CW23 with Peiai 64 (PA64),an elite indica small-grain cultivar.Using QTL analysis,17 QTLs for five grain traits were detected on four different chromosomes.Eight of the QTLs were newly-identified in this study.In particular,qGL3-1,a newly-identified grain length QTL with the highest LOD value and largest phenotypic variation,was fine-mapped to the 17 kb region of chromosome 3.A serine/threonine protein phosphatase gene encoding a repeat domain containing two Kelch motifs was identified as the unique candidate gene corresponding to this QTL.A comparison of PA64 and CW23 sequences revealed a single nucleotide substitution (C→A) at position 1092 in exon 10,resulting in replacement of Asp (D) in PA64 with Glu (E) in CW23 for the 364th amino acid.This variation is located at the D position of the conserved sequence motif AVLDT of the Kelch repeat.Genetic analysis of a near-isogenic line (NIL) for qGL3-1 revealed that the allele qGL3-1 from CW23 has an additive or partly dominant effect,and is suitable for use in molecular marker-assisted selection.Zejun Hu Haohua He Shiyong Zhang Fan Sun Xiaoyun Xin Wenxiang Wang Xi Qian Jingshui Yang Xiaojin Luo 2012Journal of Integrative Plant Biology2012,54,12:41
20Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF.Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun 2018Science China(Life Sciences)2018,61,12:43
