1Reactive capillary hemangiomas: a novel dermatologic toxicity following anti-PD-1 treatment with SHR-1210显示文摘Objective: SHR-1210 is a new and promising anti-PD-1 agent for solid tumors. During the phase I study of SHR-1210, we encountered a novel but prevalent immune-related dermatologic toxicity: reactive capillary hemangiomas(RCHs). Thus we tried to summarize the features of RCHs and estimate their relationship with tumor response.Methods: This prospective observational study systematically enrolled 98 patients with advanced solid tumors from April 27th,2016 to June 8th, 2017 in the context of the phase I clinical study of SHR-1210. This report focused on the skin toxicities. Patients underwent entire skin inspection every two weeks while taking medication. The clinical course of RCHs was recorded and their association with tumor response was estimated. The data cut-off date was November 15th, 2017.Results: After a median follow-up of 242(range, 29–567) days, RCHs were observed in 85.7%(84/98) of patients on cutaneous/mucosal surfaces; 84.5%(71/84) of the RCHs were evaluated as grade 1 adverse events. No grade 3 or 4 RCHs were observed. The time of onset of RCHs was dose dependent and shortest in the 400 mg-dose cohort(P < 0.001). Spontaneous and complete regression of RCHs was observed both during and after treatment. The objective response rate of tumors for patients with RCHs was 28.9%(24/83). However, no responders were observed among the patients without RCHs.Conclusions: RCHs were prevalent but manageable during treatment with SHR-1210. It might add to the expanding literature regarding immune-related dermatologic adverse events.Xuelian Chen Lanying Ma Xi Wang Hongnan Mo Dawei Wu Bo Lan Dong Qu Hongtu Zhang Jing Huang Binghe Xu 2019Cancer Biology & Medicine2019,16,1:53

4Immunohistochemical study on p53,H-rasp21,c-erbB-2 protein and PCNA expression in HCC tissues of Hart and minority ethnic patients显示文摘AIM To find out the difference of humanprimary liver carcinogenesis between Han andminority ethnic patients in Xinjiang.METHODS Expression of p53,c-erbB-2,H-rasp21 protein and proliferating cell nuclearantigen(PCNA)in tumor tissues of 50 patients(Han 38,minority 12)with primary hepaticcarcinoma was detected byimmunohistochemistry(LSAB).RESULTS The positive frequency of p53,c-erbB-2,H-rasp21 and PCNA expression was46.0%(23/50),70.0%(35/50),68.0%(34/50)and 82.0%(41/50)in tumor tissues;4.0%(2/50),22.0%(11/50),64.0%(32/50)and 52.0%(26/ 50)in peritumors respectively and asignificant difference,except for H-rasp21,ofoncogene alteration was found(P<0.05)between tumor and non-tumorous tissues.Combined the three oncogenes alteration,26%(13/50)tumor tissues had positiveimmunoreactivity,but in peritumor and normallivers it was negative.The positive rate of p53,c-erbB-2 and H-rasp21 protein expression was39.5%(15/38),60.5%(23/38)and 39.5%(15/38)in tumors of Han patients;66.7%(8/12),100%(12/12)and 75.0%(9/12)in minoritiesrespectively,with statistical difference (P<0.05).CONCLUSION Overexpression of p53,c-erbB-2and H-rasp21 in human primary liver carcinoma isan important biomarker of genetic alteration.The different frequency of these oncogeneticchanges may reflect some environmental or/andethnic hereditary factors affecting the livercarcinogenesis.The special life style of Han,Uygur,Kazak and Mongolia nationalities inXinjiang may also be related to theetiopathogenesis of this disease.Guo Yue Lin Zhao Lun Chen Cai Mo Lu Ying Li Xiao Jia Ping Rong Huang Department of Laboratory Medicine,Chinese PLA 474 Hospital,Urumqi 830011,Xinjiang Uygur Autonomic Region,China Department of Pathology,the 1st Teaching Hospital,Xinjiang Medical University,Urumqi 830054,Xinjiang Uygur Autonomic Region,China 2000World Journal of Gastroenterology2000,6,2:40
5Perturbed Solving Method for Interdecadal Sea-air Oscillator Model显示文摘A coupled system of the interdecadal sea-air oscillator model is studied.The El Nio-southern oscillation(ENSO) atmospheric physics oscillation is an abnormal phenomenon involved in the tropical Pacific ocean-atmosphere interactions.The oscillator model is involved with the variations of both the eastern and western Pacific anomaly pat-terns.This paper proposes an ENSO atmospheric physics model using a method of the perturbation theory.The aim is to create an asymptotic solving method for the ENSO model.Employing the perturbed method,the asymptotic solution of corresponding problem is obtained,and the asymptotic behaviour of the solution is studied.Thus we can obtain the prognoses of the sea surface temperature anomaly and related physical quantities.MO Jiaqi LIN Yihua LIN Wantao CHEN Lihua 2012Chinese Geographical Science2012,22,1:38
6Stenting for symptomatic intracranial arterial stenosis in China:1-year outcome of a multicentre registry study显示文摘background and purpose A multicentre prospective registry study of individually tailored stenting for a patient with symptomatic intracranial atherosclerotic stenosis(ICAS)combined with poor collaterals in China showed that the short-term safety and efficacy of stenting was acceptable.However,it remained uncertain whether the low event rate could be of a long term.We reported the 1-year outcome of this registry study to evaluate the long-term efficacy of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Methods Patients with symptomatic ICAS caused by 70%-99% stenosis located at the intracranial internal carotid,middle cerebral,intracranial vertebral or basilar arteries combined with poor collaterals were enrolled.Balloon-mounted stent or balloon plus self-expanding stent were selected based on the ease of vascular access and lesion morphology determined by the operators.The primary outcome was the rate of 30-day stroke,transient ischaemic attack and death,and 12-month ischaemic stroke within the same vascular territory,haemorrhagic stroke and vascular death after stenting.results From September 2013 to January 2015,300 patients(ages 58.3±9.78 years)were recruited.Among them,159 patients were treated with balloon-mounted stent and 141 with balloon plus self-expanding stent.During the 1-year follow-up,25 patients had a primary end point event.The probability of primary outcome at 1 year was 8.1%(95% CI 5.3% to 11.7%).In 76 patients with digital subtraction angiography follow-up,27.6%(21/76)had re-stenosis≥50% and 18.4%(14/76)had re-stenosis≥70%.No baseline characteristic was associated with the primary outcome.Conclusion The event rate remains low over 1 year of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Further randomised trial of comparing individually tailored stenting with best medical therapy is needed.Ning Ma Yong Zhang Jie Shuai Changchun Jiang Qiyi Zhu Kangning Chen Li Liu Baomin Li Xiangqun Shi Lianbo Gao Yajie Liu Feng Wang Yongli Li Tieyan Liu Hongbo Zheng Dapeng Mo Feng Gao Yilong Wang Yongjun Wang Lei Feng Zhongrong Miao 2018Stroke & Vascular Neurology2018,3,3:29
7Active phase compensation of quantum key distribution system显示文摘Quantum key distribution (QKD) system must be robust enough in practical communication. Besides birefringence of fiber, system performance is notably affected by phase drift. The Faraday-Michelson QKD system can auto-compensate the birefringence of fiber, but phase shift is still a serious problem in its practical operation. In this paper, the major reason of phase drift and its effect on Faraday- Michel- son QKD system is analyzed and an effective active phase compensation scheme is proposed. By this means, we demonstrate a quantum key distribution system which can stably run over 37-km fiber in practical working condition with the long-time averaged quantum bit error rate of 1.59% and the stan- dard derivation of 0.46%. This result shows that the active phase compensation scheme is suitable to be used in practical QKD systems based on double asymmetric interferometers without additional de- vices and thermal controller.CHEN Wei HAN ZhengFu MO XiaoFan XU FangXing WEI Guo GUO GuangCan 2008Chinese Science Bulletin2008,53,9:24
8Ten 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
9Diagnostic value of magnetic resonance cholangiopancreatography in choledocholithiasis显示文摘AIM:To evaluate the diagnostic accuracy of magnetic resonance cholangiopancreatography(MRCP) in patients with choledocholithiasis.METHODS:We systematically searched MEDLINE,EMBASE,Web of Science,and Cochrane databases for studies reporting on the sensitivity,specificity and other accuracy measures of diagnostic effectiveness of MRCP for detection of common bile duct(CBD) stones.Pooled analysis was performed using random effects models,and receiver operating characteristic curves were generated to summarize overall test performance.Two reviewers independently assessed the methodological quality of studies using standards for reporting diagnostic accuracy and quality assessment for studies of diagnostic accuracy tools.RESULTS:A total of 25 studies involving 2310 patients with suspected choledocholithiasis and 738 patients with CBD stones met the inclusion criteria.The average inter-rater agreement on the methodological quality checklists was 0.96.Pooled analysis of the ability of MRCP to detect CBD stones showed the following effect estimates:sensitivity,0.90(95%CI:0.88-0.92,χ2 = 65.80; P < 0.001); specificity,0.95(95%CI:0.93-1.0,χ2 = 110.51; P < 0.001); positive likelihood ratio,13.28(95%CI:8.85-19.94,χ2 = 78.95; P < 0.001); negative likelihood ratio,0.13(95%CI:0.09-0.18,χ2 = 6.27; P < 0.001); and diagnostic odds ratio,143.82(95%CI:82.42-250.95,χ2 = 44.19; P < 0.001).The area under the receiver operating characteristic curve was 0.97.Significant publication bias was not detected(P = 0.266).CONCLUSION:MRCP has high diagnostic accuracy for the detection of choledocholithiasis.MRCP should be the method of choice for suspected cases of CBD stones.Wen Chen Jing-Jia Mo Li Lin Chao-Qun Li Jian-Feng Zhang 2015World Journal of Gastroenterology2015,21,11:21
10Changed clinical aspects of primary liver cancer in China during the past 30 years显示文摘BACKGROUND: Primary liver cancer (PLC) is one of the most frequently seen tumors in China. Thirty years ago, patients with PLC were often detected at relatively late stage, with a palpable mass or marked clinical symptoms and poor prognosis. In the past 30 years, the diagnosis and treatment of PLC have been greatly improved with better prognosis. METHODS: In order to study the changes of PLC during the 30 years, the clinical data of 3250 patients with PLC from 10 medical institutions of China were collected, ana- lyzed , and compared with those of 3254 PLC patients be- fore the 30 years. RESULTS: In the 3250 patients aged 1-80 years, with an average age of 49.1 years, the male to female ratio (2.3:1) was lower than that before the 30 years. 73.5% of the 3250 patients sought medical advice within 3 months after the onset of the disease in contrast to 63.8% before the 30 years. Compared with those patients before the 30 years the symptoms and signs were alleviated generally. The HBsAg positive rate was 81.0%, but the HCV-Ab positive rate was 13.2%. The AFP level in 75% of patients was elevated, but in the remaining 25% was normal. 1912 patients (58.8%) were confirmed pathologically. Among them 1755 patients (91.8%) had hepatocellular carcinoma. The overall resec- tion rate was 46.3%. Those who had early, middle, late stage carcinoma accounted for 29.9%, 51.5%, and 18.6%respectively in contrast to 0.4%, 47.0%, and 52.6% repor- ted before the 30 years. The 1-, 3-, 5-year survival rates of the patients were 66.1%, 39.7%, and 32.5% respectively, whereas 93.5%, 70.1%, and 59.1% for the early stage pa- tients, and 65.3%, 30.5%, and 23.5% for the middle stage patients. The half and 1-year survival rates of the late stage patients were 52.5%, and 14.7%, respectively. CONCLUSION: Comparison with the clinical data before and after the 30 years show that PLC can be diagnosed ear- ly. More PLC patients tend to undergo resection while re- ceiving a better conservative treatment, which ensures a prognosis.Bing-Hui Yang, Jing-Lin Xia, Li-Wen Huang, Zhao-You Tang, Ming-Shan Chen, Jin-Qing Li, An-Min Liang, Qin-Guo Mo, Hui-Shan Lu, Chao-Liu Dai, Lu-Nan Yan, Zhi-Jian Yu, Rong-Sheng Rao, Le-Qun Li, Zhi-Xiong Su, Zhuang-Wei Fang Shanghai, China Liver Cancer Institute & Zhongshan Hospital, Fudan University, Shanghai 200032, China Tumor Hospital, Zhongshan University, Guangzhou 510000, China Tumor Hospital, Guangxi Medical Universi- ty, Nanning 530000, China Xiehe Hospital, Fujian Medical University, Fuzhou 350000, China Second Hos- pital, Chinese Medical University, Shenyang 110000, China Huaxi Hospital, Sichuan University, Chengdu 610041, China Hospital Affiliated to Nantong Medical University, Nantong 226000 , China Second Hospital, Jiangxi Medical University, Nanchang 330000 , China First Hospital Affiliated to Guangxi Medical University, Nanning 530000 , China People’s Hospital of Hainan Province, Haikou 570000, China 2004Hepatobiliary & Pancreatic Diseases International2004,3,2:20
11Inhibitory effects of emodin, baicalin, schizandrin and berberine on hef A gene: Treatment of Helicobacter pylori-induced multidrug resistance显示文摘AIM: To investigate the inhibitory effects of emodin, baicalin, etc.on the hefA gene of multidrug resistance(MDR) in Helicobacter pylori(H.pylori).METHODS: The double dilution method was used to screen MDR H.pylori strains and determine the minimum inhibitory concentrations(MICs) of emodin, baicalin, schizandrin, berberine, clarithromycin, metronidazole, tetracycline, amoxicillin and levofloxacin against H.pylori strains.After the screened MDR stains were treated with emodin, baicalin, schizandrin or berberine at a 1/2 MIC concentration for 48 h, changes in MICs of amoxicillin, tetracycline, levofloxacin, metronidazole and clarithromycin were determined.MDR strains with reduced MICs of amoxicillin were selected to detect the hefA mR NA expression by realtime quantitative PCR.RESULTS: A total of four MDR H.pylori strains were screened.Treatment with emodin, baicalin, schizandrin and berberine significantly decreased the MICs of amoxicillin and tetracycline against some strains, decreased by 1 to 2 times, but did not significantly change the MICs of clarithromycin, levofloxacin, and metronidazole against MDR strains.In the majority of strains with reduced MICs of amoxicillin, hef A m RNA expression was decreased; one-way ANOVA(SPSS 12.0) used for comparative analysis, P < 0.05.CONCLUSION: Emodin, baicalin, schizandrin and berberine significantly decreased the MICs of amoxicillin and tetracycline against some H.pylori strains, possibly by mechanisms associated with decreasing hefA mR NA expression.Yan-Qiang Huang Gan-Rong Huang Ming-Hui Wu Hua-Ying Tang Zan-Song Huang Xi-Han Zhou Wen-Qiang Yu Jian-Wei Su Xiao-Qiang Mo Bing-Pu Chen Li-Juan Zhao Xiao-Feng Huang Hong-Yu Wei Lian-Deng Wei 2015World Journal of Gastroenterology2015,21,14:20

14Effect of domperidone therapy on nocturnal dyspeptic symptoms of functional dyspepsia patients显示文摘AIM:To investigate the incidence of nocturnal dyspeptic symptoms in patients with functional dyspepsia(FD) and whether prokinetic drugs can alleviate them. METHODS:Eighty-five consecutive Chinese patients with FD were included in this study.One week after single-blinded placebo run-in treatment,baseline nocturnal intragastric pH,bile reflux and nocturnal dyspeptic symptoms of eligible patients,including epigastric pain or discomfort,abdominal distention and belching, were investigated with questionnaires.Patients exhibiting nocturnal dyspeptic symptoms were randomly and double-blindly assigned to domperidone group or placebo group.Nocturnal intragastric pH and percentage of duodenogastric bile reflux time were determined after treatment. RESULTS:Of the 85 FD patients,2 females withoutnocturnal symptoms,who responded to placebo run-in treatment,were excluded from the study,30(36.1%) exhibited nocturnal dyspeptic symptoms with increased duodenogastric bile reflux time(intragastric bilirubin absorbance>0.14)and mean gastric pH(confirming the existence of bile reflux)(P=0.021,0.023) at night were included in the study.Of these 30 patients,21(70%)had overt nocturnal duodenogastric bile reflux,which was significantly higher than that of those without nocturnal symptoms(P=0.026).The 30 patients were allocated to domperidone group or placebo group(n=15).The nocturnal duodenogastric bile reflux and gastric pH were significantly decreased after domperidone treatment(P=0.015,0.021).The severity score of nocturnal dyspeptic symptoms was also significantly decreased after domperidone treatment (P=0.010,0.015,0.026),which was positively correlated with the reduced nocturnal bile reflux or gastric pH(r=0.736,0.784,0.753 or r=0.679,0.715,0.697, P=0.039,0.036,0.037 or P=0.043,0.039,0.040). CONCLUSION:A subgroup of Chinese FD patients show overt nocturnal dyspeptic symptoms,which may be correlated with the excessive nocturnal duodenogastric bile reflux.Domperidone therapy can alleviate these symptoms.Chen, Sheng-Liang Ji, Jie-Ru Xu, Ping Cao, Zhi-Jun Mo, Jian-Zhong Fang, Jing-Yuan Xiao, Shu-Dong 2010World Journal of Gastroenterology2010,16,5:18

16Daclatasvir plus asunaprevir in treatment-na?ve patients with hepatitis C virus genotype 1b infection显示文摘AIM To assess daclatasvir plus asunaprevir(d UAL) in treatment-na?ve patients from China's Mainland, Russia and South Korea with hepatitis C virus(HCV) genotype 1 b infection. METHODS Patients were randomly assigned(3:1) to receive 24 wk of treatment with d UAL(daclatasvir 60 mg once daily and asunaprevir 100 mg twice daily) beginning on day 1 of the treatment period(immediate treatment arm) or following 12 wk of matching placebo(placebodeferred treatment arm). The primary endpoint was a comparison of sustained virologic response at posttreatment week 12(SVR12) compared with the historical SVR rate for peg-interferon plus ribavirin(70%) among patients in the immediate treatment arm. The first 12 wk of the study were blinded. Safety was assessed in d UAL-treated patients compared with placebo patients during the first 12 wk(doubleblind phase), and during 24 wk of d UAL in both arms combined.RESULTS In total, 207 patients were randomly assigned to immediate(n = 155) or placebo-deferred(n = 52) treatment. Most patients were Asian(86%), female(59%) and aged < 65 years(90%). Among them, 13% had cirrhosis, 32% had IL28 B non-CC genotypes and 53% had baseline HCV RNA levels of ≥ 6 million IU/m L. Among patients in the immediate treatment arm, SVR12 was achieved by 92%(95% confidence interval: 87.2-96.0), which was significantly higher than the historical comparator rate(70%). SVR12 was largely unaffected by cirrhosis(89%), age ≥ 65 years(92%), male sex(90%), baseline HCV RNA ≥ 6 million(89%) or IL28 B non-CC genotypes(96%), although SVR12 was higher among patients without(96%) than among those with(53%) baseline NS5 A resistanceassociated polymorphisms(at L31 or Y93 H). during the double-blind phase, aminotransferase elevations were more common among placebo recipients than among patients receiving d UAL. during 24 wk of d UAL therapy(combined arms), the most common adverse events(≥ 10%) were elevated alanine aminotransferase and upper respiratory tract infection; emergent grade 3-4 laboratory abnormalities were infrequently observed, and all grade 3-4 aminotransferase abnormalities(alanine aminotransferase, n = 9; aspartate transaminase, n = 6) reversed within 8-11 d. Two patients discontinued d UAL treatment; one due to aminotransferase elevations, nausea, and jaundice and the other due to a fatal adverse event unrelated to treatment. There were no treatment-related deaths.CONCLUSION d UAL was well-tolerated during this phase 3 study, and SVR12 with d UAL treatment(92%) exceeded thehistorical SVR rate for peg-interferon plus ribavirin of 70%.Lai Wei Fu-Sheng Wang Ming-Xiang Zhang Ji-Dong Jia Alexey A Yakovlev Wen Xie Eduard Burnevich Jun-Qi Niu Yong Jin Jung Xiang-Jun Jiang Min Xu Xin-Yue Chen Qing Xie Jun Li Jin-Lin Hou Hong Tang Xiao-guang Dou Yash Gandhi Wen-Hua Hu Fiona McPhee Stephanie Noviello Michelle Treitel Ling Mo Jun Deng 2018World Journal of Gastroenterology2018,24,12:17
17CT arterial portography and CT hepatic arteriography in detection of micro liver cancer显示文摘AIM To recognize the characteristic findings of micrQliver cancer (MLC) and to evaluate the effect of CT arterial portography (CTAP) and CT hepatic arteriography (CTHA) in diagnosis of MLC. METHODS Between April 1996 to December 1998, CTAP and CTHA were performed in 12patients with MLC, which were not detect ed byconventional CT examinations. After CTHA, 3 mL-- 5 mL mixture of lipiodol, doxorubic in andmitomycin C were injected into hepatic arterythrough the catheter, and then followed up by CTthree or four weeks later (Lipiodol CT LP-CT).RESULTS A total of 22 micro--tumors (0 .2 cm 0.6 cm in diameter ) were detected in 12patients, which manifested as small perfusiondefects in CTAP and small round enhancement inCTHA. The rate of detectability of CTAP andCTHA was 68.2% (15/ 22) and 77.3% (17/ 22)respectively, and the rate of the simultaneoususe of both procedures reached 86. 4% (19/ 22 ).All micro--tumors were demonstrated as punctatelipiodol deposit fool in LP--CT. After LP--CT, theelevated serum level of Q-fetoprotein (AFP)dropped to the normal level in all patients.CONCLUSION The CTAP and CTHA are the mostsensitive imaging methods for detecting microIiver cancer.

18Genome sequences of horticultural plants:past,present,and future显示文摘Horticultural plants play various and critical roles for humans by providing fruits,vegetables,materials for beverages,and herbal medicines and by acting as ornamentals.They have also shaped human art,culture,and environments and thereby have influenced the lifestyles of humans.With the advent of sequencing technologies,there has been a dramatic increase in the number of sequenced genomes of horticultural plant species in the past decade.The genomes of horticultural plants are highly diverse and complex,often with a high degree of heterozygosity and a high ploidy due to their long and complex history of evolution and domestication.Here we summarize the advances in the genome sequencing of horticultural plants,the reconstruction of pan-genomes,and the development of horticultural genome databases.We also discuss past,present,and future studies related to genome sequencing,data storage,data quality,data sharing,and data visualization to provide practical guidance for genomic studies of horticultural plants.Finally,we propose a horticultural plant genome project as well as the roadmap and technical details toward three goals of the project.Fei Chen Yunfeng Song Xiaojiang Li Junhao Chen Lan Mo Xingtan Zhang Zhenguo Lin Liangsheng Zhang 2019Horticulture Research2019,6,1:16

20Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders: executive summary and 2019 update of clinical management of cerebral venous sinus thrombosis显示文摘Aim Cerebral venous sinus thrombosis(CVST)is a less common cerebrovascular disease that predominantly affects young patients.The incidence of CVST is 2-5/10000000/year,accounting for 0.5%-1%of all stroke.To reduce mortality and morbidity associated with CVST,Chinese Stroke Association commissioned the authors to write the current guideline on the management of CVST.Methods PubMed(MEDLINE),CNKI and Wanfang database were searched for studies related to CVST from 1 January 1990 to 31 July 2019.Data were synthesised by evidence tables.Each recommendation was fully discussed by the writing group members and reviewed by Chinese Stroke Association Stroke Fellow Committees.Levels of evidence grading algorithm of Chinese Stroke Association was used to grade each recommendation.results This guideline mainly focuses on the diagnostic evaluation,therapeutic strategies and secondary prevention of CVST.CT/CTV and MRI/MRV are recommended in the initial imaging evaluation of patients with suspected CVST.Anticoagulation therapy with low-molecular weight heparin should be initiated in patients with CVST immediately.After the acute stage,warfarin is recommended for 3-6 months to prevent the recurrence of CVST and other venous thromboembolic events.Conclusions The guideline summarises the current evidence regarding the management of CVST,and provides references for diagnosis,treatment and secondary prevention of CVST in China.Yuhua Fan Jian Yu Hongbing Chen Jian Zhang Jiangang Duan Dapeng Mo Wenhao Zhu Bo Wang Fubing Ouyang Yicong Chen Linfang Lan Jinsheng Zeng Chinese Stroke Association Stroke Council CVST Guideline Writing Committee 2020Stroke & Vascular Neurology2020,5,2:14
