1Sodium 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
2A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161

4Relationship between plasma D(-)-lactate and intestinal damage after severe injuries in rats显示文摘AIM To explore the kinetic changes in plasma D (-)lactate and lipopolysaccharide ( LPS ) levels, and investigate whether D (-)-lactate could be used as a marker of intestinal injury in rats following gut ischemia/reperfusion, burn, and acute necrotizing pancreatitis (ANP).METHODS Three models were developed in rats:gut ischemia/reperfusion obtained by one hour of superior severe burn injury created by 30% of total body surface induced by continuous inverse infusion of sodium taurocholate and trypsin into main pancreatic duct.Plasma levels of D( - )-lactate in systemic circulation and LPS in portal circulation were measured by enzymaticspectrophotometric method and limulus amebocyte lysate (LAL) test kit, respectively. Tissue samples of intestine were taken for histological analysis.RESULTS One hour gut ischemia followed by reperfusion injuries resulted in a significant elevation in plasma D( - )lactate and LPS levels, and there was a significant correlation between the plasma D( - )-lactate and LPS (r =0.719, P<0.05). The plasma concentrations of D(-)lactate and LPS increased significantly at 6 h postburn,and there was also a remarkable correlation between them (r = 0.877, P < 0.01). D ( - )-lactate and LPS levels elevated significantly at 2 h after ANP, with a similar significant correlation between the two levels (r-0.798,P < 0.01 ). The desquamation of intestine villi and infiltration of inflammatory cells in the lamina propria were observed in all groups.CONCLUSION The changes of plasma D( - )-lactate levels in systemic blood paralleled with LPS levels in the portal vein blood. The measurement of plasma D (-)-lactate level may be a useful marker to assess the intestinal injury and to monitor an increase of intestinal permeability and endotoxemia following severe injuries in early stage.Xiao-Qing Sun Xiao-Bing Fu Rong-Zhan Yi Lü Qun Deng Xiao-Guo Jian Zhi-Yong Sheng Bum Institute, 304~(th)Hospital,Beijing 100037,China Department of General Surgery,Chinese PLA 304 Hospital,Beijing 100037,China 2001World Journal of Gastroenterology2001,7,4:56

6Multiple genetic alterations and behavior of cellular biology in gastric cancer and other gastric mucosal lesions:H.pylori infection,histological types and staging显示文摘AIM To investigate the expression of multiplegenes and the behavior of cellular biology ingastric cancer(GC)and other gastric mucosallesions and their relations to Helicobacter pylori(H.pylori)infection,tumor staging andhistological subtypes.METHODS Three hundred and twenty-sevenspecimens of gastric mucosa obtained viaendoscopy or surgical resection,and ABCimmunohistochemical staining were used todetect the expression of p53,p16,Bcl-2 andCOX-2 proteins.H.pylori was determined byrapid urea test combined with pathologicalstaining or14C urea breath test.Cellular image analysis was performed in 66 patients withintestinal metaplasia(IM)and/or dysplasia(Dys).In 30 of them,both cancer and theparacancerous tissues were obtained at the timeof surgery.Histological pattern,tumor staging,lymph node metastasis,grading ofdifferentiation and other clinical data werestudied in the medical records.RESULTS p16 expression of IM or Dys wassignificantly lower in positive H.pylori chronicatrophic gastritis(CAG)than those withnegative H.pylori(CAG:54.8% vs 88.0%,IM:34.4% vs 69.6%,Dys:23.8% vs 53.6%,allP<0.05),Bcl-2 or COX-2 expression of IM orDys in positive H.pylori cases was significantlyhigher than that without H.pylori(Bcl-2:68.8%vs23.9%,90.5% vs 60.7%;COX-2:50.0% vs10.8%,61.8% vs 17.8%;all P<0.05).Themean number of most parameters of cellularimage analysis in positive H.pylori group wassignificantly higher than that in negative H.pylori group(Ellipser:53±14,40±12μm,Area1:748±572,302±202 μm2,Area2:3050±1661,1681±1990 μm2,all P<0.05;Ellipseb:79±23,58±15 μm,Ratio1:22%±5%,13%±4%,Ratio2:79%±17%,53%±20%,all P<0.01).There was significant correlation between Bcl-2and histologic pattern of gastric carcinoma,andbetween COX-2 and tumor staging or lymph nodemetastasis(Bcl-2:75.0% vs 16.7%;COX-2:76.0% vs 20.0%,79.2% vs 16.7%;allP<0.05).CONCLUSION p1l6, Bcl-2, and COX-2 but not p53 gene may play a role in the early genesis/ progression of gastric carcinoma and are associated with H. pylori infection. p53 gene is relatively late event in gastric tumorigenesis and mainly relates to its progression. There is more cellular-biological behavior of malignant tumor in gastric mucosal lesions with H. pylori infection. Aberrant Bcl-2 protein expression appears to be preferentially associated with the intestinal type cancer. COX-2 seems to be related to tumor staging and lymph node metastasis.Heng Jun Gao Lian Zhen Yu Jian Feng Bai Yan Shen Peng Gu Sun Han Lin Zhao Kun Miu Xiu Zhen Lü Xiao Yong Zhang Zhi Quan Zhao 2000World Journal of Gastroenterology2000,6,6:52
7Renewable Energy Transmission by HVDC Across the Continent:System Challenges and Opportunities显示文摘Rapid development of renewable energy in China is driving a major shift in the characteristics and control requirements of the electricity grid.Since the best renewable energy resources are far away from load centers in the east and southeast,transmission over long distances is required.Over 20 high-voltage DC(HVDC)transmission lines,with a combined capacity exceeding 150 GW,are in operation or are currently under construction.This rapid expansion of new generation and transmission capacities based on power electronics starts to change the characteristics of the grid,especially in areas where they concentrate,creating new stability problems and operational challenges.New system theories and technologies are required to support the development and operation of a future grid that relies more and more on power electronics.This paper highlights the characteristics of power electronics as used in renewable energy generation and HVDC transmission systems,discusses the impacts of these power-electronics-based assets on grid stability and operational requirements,and identifies opportunities for the development of both new system theories and system technologies to support a national energy policy that emphasizes the use of clean energy.Jian Sun Mingjie Li Zhigang Zhang Tao Xu Jingbo He Haijiao Wang Guanghui Li 2017CSEE Journal of Power and Energy Systems2017,3,4:43

9Efficacy of imatinib dose escalation in Chinese gastrointestinal stromal tumor patients显示文摘AIM:To investigate the efficacy and safety of imatinib dose escalation in Chinese patients with advanced gastrointestinal stromal tumor (GIST).METHODS:Advanced GIST patients previously failing 400 mg imatinib treatment were enrolled in this study.Patients received imatinib with dose escalation to 600 mg/d,and further dose escalation to 800 mg/d if imatinib 600 mg/d failed.Progression-free survival,overall survival,clinical efficacy,c-kit/PDGFRA genotype and safety were evaluated.RESULTS:52 patients were enrolled in this study.For the 47 evaluable patients receiving imatinib (600 mg/d),the disease control rate was 40.4%,and the median progression-free survival for all patients was 17 wk (95% CI:3.9-30.1).The median overall survival after dose escalation was 81 wk (95% CI:36.2-125.8).Adverse events,mainly edema,fatigue,granulocytopenia and skin rash were tolerable.However,further dose escalation (800 mg/d) in 14 cases was ineffective,with disease progression and severe adverse events.Among 30 cases examined for gene mutations,patients with exon 9 mutations experienced a better progression-free survival of 47 wk.CONCLUSION:Imatinib dose escalation to 600 mg/d is more appropriate for Chinese patients and may achieve further survival benefit.Jian Li Ji-Fang Gong Jie Li Jing Gao Nai-Ping Sun Lin Shen 2012World Journal of Gastroenterology2012,18,7:35
10Deferoxamine promotes recovery of traumatic spinal cord injury by inhibiting ferroptosis显示文摘Ferroptosis is an iron-dependent novel cell death pathway. Deferoxamine, a ferroptosis inhibitor, has been reported to promote spinal cord injury repair. It has yet to be clarified whether ferroptosis inhibition represents the mechanism of action of Deferoxamine on spinal cord injury recovery. A rat model of Deferoxamine at thoracic 10 segment was established using a modified Allen's method. Ninety 8-week-old female Wistar rats were used. Rats in the Deferoxamine group were intraperitoneally injected with 100 mg/kg Deferoxamine 30 minutes before injury. Simultaneously, the Sham and Deferoxamine groups served as controls. Drug administration was conducted for 7 consecutive days. The results were as follows:(1) Electron microscopy revealed shrunken mitochondria in the spinal cord injury group.(2) The Basso, Beattie and Bresnahan locomotor rating score showed that recovery of the hindlimb was remarkably better in the Deferoxamine group than in the spinal cord injury group.(3) The iron concentration was lower in the Deferoxamine group than in the spinal cord injury group after injury.(4) Western blot assay revealed that, compared with the spinal cord injury group, GPX4, xCT, and glutathione expression was markedly increased in the Deferoxamine group.(5) Real-time polymerase chain reaction revealed that, compared with the Deferoxamine group, mRNA levels of ferroptosis-related genes Acyl-CoA synthetase family member 2(ACSF2) and iron-responsive element-binding protein 2(IREB2) were up-regulated in the Deferoxamine group.(6) Deferoxamine increased survival of neurons and inhibited gliosis. These findings confirm that Deferoxamine can repair spinal cord injury by inhibiting ferroptosis. Targeting ferroptosis is therefore a promising therapeutic approach for spinal cord injury.Xue Yao Yan Zhang Jian Hao Hui-Quan Duan Chen-Xi Zhao Chao Sun Bo Li Bao-You Fan Xu Wang Wen-Xiang Li Xuan-Hao Fu Yong Hu Chang Liu Xiao-Hong Kong Shi-Qing Feng 2019Neural Regeneration Research2019,14,3:35
11Metastatic human hepatocellular carcinoma models in nude mice and cell line with metastatic potential显示文摘Metastatic human HCC model is needed for the studies on mechanism and intervention of metastatic recurrence. By using orthotopic implantation of histologically intact tissues of 30 surgical specimens, a patient like metastatic model of human HCC in nude mice (LCI-D20)and a Iow metastatic model of human HCC in nude mice LCI-D35 ) have been established. All mice with transplanted LCI-D20 tumors exhibited extremely high metastatic ability including spontaneous metastasis to liver, lungs, lymph nodes and peritoneal seeding.Remarkable difference was also found in expression of some of the invasiveness related genes and growth factors between the LCI-D20 and LCI-D35 tumors. PAI-Iincreased gradually following tumor progression in LCID20 model, and correlated with tumor size and AFP level,Phasic expression of tissue intercellular adhesion molecule-I in this model was also observed. Using corneal micropocket model, it was demonstrated that the vascular response induced by LCI-D20 tumor was stronger than that induced by LCI-D35 tumor. Similar report on metastatic human HCC model in nude mice and human HCC cell line with metastatic potential was rarely found in the literature. This LCI-D20 model has been widely used for the studies on intervention of metastasis, including antiangiogenesis, antisense approach, metalloproteinase inhibitor, differentiation inducer, etc. It is concluded that the establishment of metastatic human HCC model in nude mice and human HCC cell line with metastatic potential will provide important models for the in vivo and in vitro study of HCC invasiveness, angiogenesis as well as intervention of HCC recurrence.Zhao-You Tang Fan-Xian Sun Jian Tian Sheng-Long Ye Yin-Kun Liu Kang-Da Liu Qiong Xue Jie Chen Jing-Lin Xia Lun-Xiu Qin Hui-Chuan Sun Lu Wang Jian Zhou Yan Li Zeng-Chen Ma Xin-Da Zhou Zhi-Quan Wu Zhi-Ying Lin Bing-Hui Yang Liver Cancer Institute of Fudan University and Zhongshan Hospital,Shanghai 200032,China 2001World Journal of Gastroenterology2001,7,5:34
12Focal autoimmune pancreatitis: Radiological characteristics help to distinguish from pancreatic cancer显示文摘AIM: To identify the radiological characteristics of focal autoimmune pancreatitis (f-AIP) useful for differentiation from pancreatic cancer (PC). METHODS: Magnetic resonance imaging (MRI) and triple-phase computed tomography (CT) scans of 79 patients (19 with f-AIP, 30 with PC, and 30 with a normal pancreas) were evaluated retrospectively. A radiologist measured the CT attenuation of the pancreatic parenchyma, the f-AIP and PC lesions in triple phases. The mean CT attenuation values of the f-AIP lesions were compared with those of PC, and the mean CT attenuation values of pancreatic parenchyma in the three groups were compared. The diagnostic performance of CT attenuation changes from arterial phase to hepatic phase in the differentiation between f-AIP and PC was evaluated using receiver operating characteristic (ROC) curve analysis. We also investigated the incidence of previously reported radiological findings for differentiation between f-AIP and PC. RESULTS: The mean CT attenuation values of f-AIP lesions in enhanced phases were significantly higher than those of PC (arterial phase: 60 ± 7 vs 48 ± 10, P < 0.05; pancreatic phase: 85 ± 6 vs 63 ± 15, P < 0.05; hepatic phase: 95 ± 7 vs 63 ± 13, P < 0.05). The mean CT attenuation values of f-AIP lesions were significantly lower those of uninvolved pancreas and normal pancreas in the arterial and pancreatic phase of CT (P < 0.001, P < 0.001), with no significant difference at the hepatic phase or unenhanced scanning (P = 0.4, P = 0.1). When the attenuation value increase was equal or more than 28 HU this was considered diagnostic for f-AIP, and a sensitivity of 87.5%, specificity of 100% and an area under the ROC curve of 0.974 (95%CI: 0.928-1.021) were achieved. Five findings were more frequently observed in f-AIP patients: (1) sausageshaped enlargement; (2) delayed homogeneous enhancement; (3) hypoattenuating capsule-like rim; (4) irregular narrowing of the main pancreatic duct (MPD) and/or stricture of the common bile duct (CBD); and (5) MPD upstream dilation ≤ 5 mm. CONCLUSION: Analysis of a combination of CT and MRI findings could improve the diagnostic accuracy of differentiating f-AIP from PC.Gao-Feng Sun Chang-Jing Zuo Cheng-Wei Shao Jian-Hua Wang Jian Zhang 2013World Journal of Gastroenterology2013,19,23:34

14The role of magmatism in the thinning and breakup of the South China Sea continental margin显示文摘INTRODUCTION Magmatism plays a key role in the process of continental margin breakup and ocean formation.Even in the extremely magma-poor Iberia and Newfoundland margin,studies of field outcrops have shown that syn-rift magmatism had participated in rifting from a very early stage and contributed directly to the rifting process.The final transition from exhumed continental mantle to the ocean formation is also triggered by the accumulation and eruption of magma[1].Zhen Sun Jian Lin Ning Qiu Zhimin Jian PinXian Wang Xiong Pang Jinyun Zheng Benduo Zhu 2019National Science Review2019,6,5:34
15Efficacy and safety of Xinfeng capsule in patients with rheumatoid arthritis:a multi-center parallel-group double-blind randomized controlled trial显示文摘OBJECTIVE:To evaluate the efficacy and safety of Xinfeng capsule in patients suffering rheumatoid arthritis(RA).METHODS:A multi-center parallel-group designed,double-blind,randomized,controlled trial was conducted.Totally 304 RA patients were assigned to two groups:one group was administered Xinfeng capsule(XFC) plus the placebo of leflunomide and the other given leflunomide(LEF) plus the placebo of XFC for twelve weeks.The clinical and laboratory parameters were compared at baseline and fourth,eighth,and twelfth weeks.RESULTS:After twelve-week treatment,patients in two groups all showed some trend of effectiveness when compared in terms of American Rheumatism Association(ACR) recommended 20%,50%,70%improvement criteria,but it was insignificant.The validity in ameliorate modified disease activity score(DAS28) and laboratory indexes as erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),rheumatoid factor(RF) were also found no difference.The score of health assessment questionnaire(HAQ),self-rating anxiety scale(SAS),self-rating depression scale(SDS) and quality of life questionnaire with rheumatoid arthritis(RAQOL)both lower than the first week and the changes showed no difference.However,the score of SDS dropped more in XFC group than in the other.A total of 147 adverse reaction cases were reported,which shows no difference between the two groups.The most common adverse reactions were hepatic impairment,anemia,leukocytopenia,epigastric discomfort and phalacrosis.CONCLUSION:XFC demonstrated better improvement in the scores of SDS and compared with those of LEF group.Liu Jian Wang Yuan Huang Chuanbing Xu Jianhua Li Zhijun Xu Liang He Liyun Sun Yue Wang Yali Xu Shengqian Zhao Ping Mao Tongjun Tan Bin Zhu Fubing Zhang Pingheng Fang Li 2015Journal of Traditional Chinese Medicine2015,35,5:27

17The South China Sea is not a mini-Atlantic: plate-edge rifting vs intra-plate rifting显示文摘The South China Sea,as‘a non-volcanic passive margin basin’in the Pacific,has often been considered as a small-scale analogue of the Atlantic.The recent ocean drilling in the northern South China Sea margin found,however,that the Iberian model of non-volcanic rifted margin from the Atlantic does not apply to the South China Sea.In this paper,we review a variety of rifted basins and propose to discriminate two types of rifting basins:plate-edge type such as the South China Sea and intra-plate type like the Atlantic.They not only differ from each other in structure,formation process,lifespan and geographic size,but also occur at different stages of the Wilson cycle.The intra-plate rifting occurred in the Mesozoic and gave rise to large oceans,whereas the plate-edge rifting took place mainly in the mid-Cenozoic,with three-quarters of the basins concentrated in the Western Pacific.As a member of the Western Pacific system of marginal seas,the South China Sea should be studied not in isolation on its origin and evolution,but in a systematic context to include also its neighboring counterparts.Pinxian Wang Chi-Yue Huang Jian Lin Zhimin Jian Zhen Sun Minghui Zhao 2019National Science Review2019,6,5:24
18Ten cities cross-sectional questionnaire survey of children asthma and other allergies in China显示文摘Asthma,rhinitis and eczema(allergic or non-allergic)have increased throughout the world during the last decades,especially among children.Changes in the indoor environment are suspected to be important causes.China has experienced a dramatic change in indoor environmental exposures during the past two decades.However,such changes and their associations with children’s asthma and other health aspects have not been thoroughly studied.China,Children,Homes,Health(CCHH),Phase I,was a cross-sectional questionnaire survey of 48219 children 1–8 years old in 10 Chinese cities during 2010–2012.The questionnaire includes the International Study of Asthma and Allergies in Childhood(ISAAC)core health questions and additional questions regarding housing,life habits and outdoor environment.In health analyses,children aged 3–6 years old were included.The prevalences of doctor diagnosed asthma varied from 1.7%to 9.8%(mean 6.8%),a large increase from 0.91%in 1999 and 1.50%in2000.The prevalence of wheeze,rhinitis and atopic eczema(last 12 months)varied from 13.9%to 23.7%,24.0%to 50.8%and4.8%to 15.8%,respectively.Taiyuan had the lowest prevalences of all illnesses and Shanghai the highest,except for wheezewhere the highest value was for Urumqi.We found(1)no obvious association between disease prevalences and ambient PM10concentrations and(2)higher prevalences of disease in humid climates with hot summers and cold winters,but with no centrally heated buildings.Associations between the diseases and economic status as indexed by Gross Domestic Product(GDP)requires further study.ZHANG YinPing LI BaiZhan HUANG Chen YANG Xu QIAN Hua DENG QiHong ZHAO ZhuoHui LI AnGui ZHAO JiaNing ZHANG Xin QU Fang HU Yu YANG Qin WANG Juan ZHANG Ming WANG Fang ZHENG XiaoHong LU Chan LIU ZhiJian SUN YueXia MO JinHan ZHAO YiLi LIU Wei WANG TingTing NORBCK Dan BORNEHAG Carl-Gustaf SUNDELL Jan 2013Chinese Science Bulletin2013,58,34:22
19Deep carbon cycles constrained by a large-scale mantle Mg isotope anomaly in eastern China显示文摘Although deep carbon recycling plays an important role in the atmospheric CO_2 budget and climate changes through geological time,the precise mechanisms remain poorly understood.Since recycled sedimentary carbonate through plate subduction is the main light-δ^(26)Mg reservoir within deep-Earth,Mg isotope variation in mantle-derived melts provides a novel perspective when investigating deep carbon cycling.Here,we show that the Late Cretaceous and Cenozoic continental basalts from 13 regions covering the whole of eastern China have low δ^(26)Mg isotopic compositions,while the Early Cretaceous basalts from the same area and the island arc basalts from circum-Paciic subduction zones have mantle-like or heavy Mg isotopic characteristics.hus,a large-scale mantle low δ^(26)Mg anomaly in eastern China has been delineated,suggesting the contribution of sedimentary carbonates recycled into the upper mantle,but limited into the lower mantle.his large-scale spatial and temporal variation of Mg isotopes in the mantle places severe constraints on deep carbon recycling via oceanic subduction.Shu-Guang Li Wei Yang Shah Ke Xunan Meng Hengci Tian Lijuan Xu Yongsheng He Jian Huang Xuan-Ce Wang Qunke Xia Weidong Sun Xiaoyong Yang Zhong-Yuan Ren Haiquan Wei Yongsheng Liu Fancong Meng Jun Yan 2017National Science Review2017,4,1:23
20Clinicopathologic characteristics and prognosis of gastroenteropancreatic neuroendocrine neoplasms: a multicenter study in South China显示文摘Background: Gastroenteropancreatic neuroendocrine neoplasms(GEP-NENs) are a heterogeneous group of rare tumors. Many issues in terms of epidemiologic features, pathogenesis, and treatment of GEP-NENs are still under discussion. Our study aimed to analyze the clinicopathologic characteristics and prognosis of Chinese patients with GEP-NENs.Methods: Complete clinicopathologic data and survival information of 1183 patients with GEP-NENs treated between 2005 and 2015 were collected from five medical centers in Guangdong Province, China. Patient survival was estimated using the Kaplan–Meier method and analyzed using the log-rank test; prognostic factors were analyzed using the Cox proportional hazards model.Results: The most common tumor location was the rectum(37.4%), followed by the pancreas(28.1%), stomach(20.7%), small intestine(7.2%), appendix(3.4%), and colon(3.3%). After initial definitive diagnosis, 1016(85.9%) patients underwent surgery. The 1-, 3-, and 5-year overall survival(OS) rates for the entire cohort were 87.9%, 78.5%, and 72.8%, respectively. The 3-year OS rates of patients with G1, G2, and G3 tumors were 93.1%, 82.7%, and 43.1%, respectively(P < 0.001). The 3-year OS rates of patients with stage I, II, III, and IV tumors were 96.0%, 87.3%, 64.0%, and 46.8%, respectively(P < 0.001). Patients with distant metastasis who underwent palliative surgery had a longer survival than those who did not(P = 0.003). Similar survival benefits of palliative surgery were observed in patients with neuroendocrine tumor(P y, M category, and sur= 0.031) or neuroendocrine carcinoma(P gery were found to be independent prog= 0.046). In multivariate analysis, age, grade, N categornostic factors.Conclusions: Patients with GEP-NENs who are women, younger than 50 years old, have smaller tumor size, have lower tumor grade, have lower T/N/M category, and who undergo surgery can have potentially longer survival time. Our data showed that surgery can improve the prognosis of GEP-NEN patients with distant metastasis. However, randomized controlled trials need to be conducted to establish the optimal criteria for selecting patients to undergo surgery.Cheng Fang Wei Wang Yu Zhang Xingyu Feng Jian Sun Yujie Zeng Ye Chen Yong Li Minhu Chen Zhiwei Zhou Jie Chen 2017Chinese Journal of Cancer2017,36,10:23
