1Artificial intelligence in healthcare:past,present and future显示文摘Artificial intelligence(AI)aims to mimic human cognitive functions.It is bringing a paradigm shift to healthcare,powered by increasing availability of healthcare data and rapid progress of analytics techniques.We survey the current status of AI applications in healthcare and discuss its future.AI can be applied to various types of healthcare data(structured and unstructured).Popular AI techniques include machine learning methods for structured data,such as the classical support vector machine and neural network,and the modern deep learning,as well as natural language processing for unstructured data.Major disease areas that use AI tools include cancer,neurology and cardiology.We then review in more details the AI applications in stroke,in the three major areas of early detection and diagnosis,treatment,as well as outcome prediction and prognosis evaluation.We conclude with discussion about pioneer AI systems,such as IBM Watson,and hurdles for real-life deployment of AI.Fei Jiang Yong Jiang Hui Zhi Yi Dong Hao Li Sufeng Ma Yilong Wang Qiang Dong Haipeng Shen Yongjun Wang 2017Stroke & Vascular Neurology2017,2,4:76
2The Chinese Stroke Association scientific statement:intravenous thrombolysis in acute ischaemic stroke显示文摘The most effective medical treatment for acute ischaemic stroke(AIS)is to offer intravenous thrombolysis during the ultra-early period of time after the onset.Even based on the Consensus of Chinese Experts on Intravenous Thrombolysis for AIS in 2012 and 2014 Chinese Guidelines on the Diagnosis and Treatment of AIS,the rate of thrombolysis for AIS in China remained around 2.4%,and the rate of intravenous tissue plasminogen activator usage was only about 1.6%in real world.The indication of thrombolysis for AIS has been expanded,and contraindications have been reduced with recently published studies.In order to facilitate the standardisation of treating AIS,improve the rate of thrombolysis and benefit patients who had a stroke,Chinese Stroke Association has organised and developed this scientific statement.Qiang Dong Yi Dong Liping Liu Anding Xu Yusheng Zhang Huaguang Zheng Yongjun Wang 2017Stroke & Vascular Neurology2017,2,3:56
3Chinese Stroke Center Alliance:a national effort to improve healthcare quality for acute stroke and transient ischaemic attack:rationale,design and preliminary findings显示文摘Background In June 2015,the Chinese Stroke Association(CSA)initiated the Chinese Stroke Center Alliance(CSCA)to establish the national hospital-based stroke care quality assessment and improvement platform.This article outlines its objectives,operational structure,patient population,quality improvement(QI)intervention tools,data elements,data collection methodology and current patient and hospital data.Methods The CSCA is a national,hospital-based,multicentre,voluntary,multifaceted intervention and continuous QI initiative.This multifaceted intervention includes stroke centre development,written care protocols,workshops and a monitoring/feedback system of evidencebased performance measures.The data coordinating centre of the CSCA resides at the China National Clinical Research Center for Neurological Diseases,Beijing Tiantan Hospital.results As of July 2017,1576 hospitals in China have contributed detailed clinical information to serve as a benchmark for the stroke care quality of 433264 patients with acute stroke/transient ischaemic attacks(TIA),including 352572(81.38%)acute ischaemic stroke,30362(7.01%)TIA,42080(9.71%)spontaneous intracranial haemorrhage,5505(1.27%)subarachnoid haemorrhage and 2745(0.63%)not specified stroke.Conclusion The CSCA programme is designed to establish a continuous national stroke registry and help healthcare providers develop stroke centres and treat patients in a consistent manner in accordance with accepted national guidelines and,ultimately,improve patient outcomes.It supports the CSA mission to reduce stroke burden in China.Yongjun Wang Zixiao Li Yilong Wang Xingquan Zhao Liping Liu Xin Yang Caiyun Wang Hongqiu Gu Fuying Zhang Chunjuan Wang Ying Xian David Z Wang Qiang Dong Anding Xu Jizong Zhao Chinese Stroke Center Alliance investigators 2018Stroke & Vascular Neurology2018,3,4:38
4Identification and standardization of maneuvers based upon operational flight data显示文摘To find a way of loads analysis from operational flight data for advanced aircraft,maneuver identification and standardization jobs are conducted in this paper. For thousands of sorties from one aircraft, after studying the flight attitude when performing actions, the start and end time of the maneuvers can be determined. According to those time points, various types of maneuvers during the flight are extracted in the form of multi-parameters time histories. By analyzing the numerical range and curve shape of those parameters, a characteristic data library is established to model all types of maneuvers. Based on this library, a computer procedure using pattern-recognition theory is programmed to conduct automatic maneuver identification with high accuracy. In that way, operational loads are classified according to maneuver type. For a group of identified maneuvers of the same type, after the processes of time normalization, trace shifting, as well as averaging and smoothing, the idealization standard time history of each maneuver type is established.Finally, the typical load statuses are determined successfully based on standard maneuvers. The proposed method of maneuver identification and standardization is able to derive operational loads effectively, and might be applied to monitoring loads in Individual Aircraft Tracking Program(IATP).Wang Yongjun Dong Jiang Liu Xiaodong Zhang Lixin 2015Chinese Journal of Aeronautics2015,28,1:13
5Factors Associated with Thrombolysis Outcome in Ischemic Stroke Patients with Atrial Fibrillation显示文摘The outcome of early intravenous thrombolysis for ischemic stroke in patients with atrial fibrillation(AF)is worse than that without thrombosis. How to increase the efficacy of intravenous thrombolysis for AF-related ischemic stroke remains largely unknown. In this study, we investigated factors that influence the effect of intravenous thrombolysis in these patients. Our results showed that thrombolysis was independently associated with a favorable outcome(P \ 0.001) and did not influence the mortality of AF-related ischemic stroke, although it increased the risk of hemorrhage within 24 h after treatment. Risk factors for a poor outcome at admission were:heart failure(P = 0.045); high systolic pressure(P = 0.039); high blood glucose(P = 0.030); and a high National Institutes of Health Stroke Scale(NIHSS) score(P \ 0.001). Moreover, high systolic pressure at admission(P = 0.007), high blood glucose(P = 0.027), and a high NIHSS score(P \ 0.001) were independent risk factors for mortality at 3 months. Besides thrombolysis, a high NIHSS score(P = 0.006) and warfarin taken within 48 h before stroke onset(P = 0.032) were also independent risk factors for symptomatic hemorrhage within 24 h after treatment. Ischemic stroke patients with AF benefited from intravenous thrombolysis with recombinant tissue plasminogen activator within 4.5 h after stroke.Qiuyun Zhao Xiaobo Li Wanli Dong Min Ye Yongjun Cao Meijuan Zhang Qiantao Cheng Junshan Zhou Guofang Chen Ming Yu Shanshan Hong Xiue Wei Bei Wang Guiyun Cui Peng Zhang Hong Ding Rongzhen Xu Yan Chen Yun Xu 2016Neuroscience Bulletin2016,32,2:13
6Clopidogrel with aspirin in High- risk patients with Acute Non- disabling Cerebrovascular Events II (CHANCE-2): rationale and design of a multicentre randomised trial显示文摘Background In patients with a minor ischaemic stroke or transient ischaemic attack(TIA),separate trials have shown that dual antiplatelet therapy with clopidogrel plus aspirin(clopidogrel-aspirin)or ticagrelor plus aspirin(ticagrelor-aspirin)are more effective than aspirin alone in stroke secondary prevention.However,these two sets of combination have not been directly compared.Since clopidogrel was less effective in stroke patients who were CYP2C19 loss-of function(LOF)allele carriers,whether ticagrelor-aspirin is clinically superior to clopidogrel-aspirin in this subgroup of patients with stroke is unclear.Aim To describe the rationale and design considerations of the Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events(CHANCE-2)trial.Design CHANCE-2 is a randomised,double-blind,double-dummy,placebo-controlled,multicentre trial that compares two dual antiplatelet strategies for minor stroke or TIA patients who are CYP2C19 LOF allele carriers:ticagrelor(180 mg loading dose on day 1 followed by 90 mg twice daily on days 2-90)or clopidogrel(300 mg loading dose on day 1 followed by 75 mg daily on days 2-90),plus open-label aspirin with a dose of 75-300 mg on day 1 followed by 75 mg daily on day 2-21.All will be followed for 1 year.Study outcomes The primary efficacy outcome is any stroke(ischaemic or haemorrhagic)within 3 months and the primary safety outcome is any severe or moderate bleeding event within 3 months.Discussion The CHANCE-2 trial will evaluate whether ticagrelor-aspirin is superior to clopidogrel-aspirin for minor stroke or TIA patients who are CYP2C19 LOF allele carriers.Yongjun Wang Claiborne Johnston Philip M Bath Xia Meng Jing Jing Xuewei Xie Anxin Wang Yuesong Pan Anding Xu Qiang Dong Yilong Wang Xingquan Zhao Zixiao Li Hao Li 2021Stroke & Vascular Neurology2021,6,2:10
7Safety and efficacy of tenecteplase versus alteplase in patients with acute ischaemic stroke (TRACE): a multicentre, randomised, open label, blinded-endpoint (PROBE) controlled phase II study显示文摘Background Tenecteplase(TNK)possesses several pharmacological characteristics superior to conventional alteplase(rt-PA),with well-established safety and efficacy profile in Caucasians.There exists controversy over the optimal dose of intravenous rt-PA for East Asians with acute ischaemic stroke(AIS).Current study aimed to determine the safety dose range of recombinant human TNK tissue-type plasminogen activator(rhTNK-tPA)for patients with AIS in China.Methods This multicentre,prospective,randomised,open-label,blinded end-point,phase II study compared three tiers of 0.1,0.25,0.32 mg/kg rhTNK-tPA(to a maximum of 40 mg)with standard 0.9 mg/kg rt-PA(to a maximum of 90 mg)in patients who were eligible for intravenous thrombolysis.The safety outcome were symptomatic intracranial haemorrhage(sICH)within 36 hours.Results Between May 2018 and February 2020,240 patients were randomly assigned to four group,4 of whom did not receive study treatment.The intention-to-treat analysis included 236 patients.There was no difference in the improvement on National Institutes of Health Stroke Scale at day 14 in the 3 tiers and control group(63.3%,77.2%,66.7%vs 62.7%).The number of sICH was 3 of 60(5.0%)in the 0.1 mg/kg group,none in the 0.25 mg/kg group,2 of 60(3.3%)in the 0.32 mg/kg group and 1(1.7%)of 59 in the rt-PA group.There were no significant between-group differences in severe adverse events.Conclusions Similar to the Caucasians,rhTNK-tPA was well tolerated in Chinese patients with AIS at all doses administered within 3 hours of symptom onset.The dose-efficacy profile of rhTNK-tPA needs to be established with future investigations.Shuya Li Yuesong Pan Ziran Wang Zhigang Liang Huisheng Chen Dong Wang Yi Sui Xingquan Zhao Yilong Wang WanLiang Du Huaguang Zheng Yongjun Wang 2022Stroke & Vascular Neurology2022,7,1:9

10Analytical validation of GMEX rapid point- of care CYP2C19 genotyping system for the CHANCE-2 trial显示文摘Background and purpose Rapid genotyping is useful for guiding early antiplatelet therapy in patients with high-risk nondisabling ischaemic cerebrovascular events(HR-NICE).Conventional genetic testing methods used in CYP2C19 genotype-guided antiplatelet therapy for patients with HR-NICE did not satisfy the needs of the Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events(CHANCE)-2 trial.Therefore,we developed the rapid-genotyping GMEX(point-of care)system to meet the needs of the CHANCE-2 trial.Methods Healthy individuals and patients with history of cardiovascular diseases(n=408)were enrolled from six centres of the CHANCE-2 trial.We compared the laboratory-based genomic test results with Sanger sequencing test results for accuracy verification.Next,we demonstrated the accuracy,timeliness and clinical operability of the GMEX system compared with laboratory-based technology(YZY Kit)to verify whether the GMEX system satisfies the needs of the CHANCE-2 trial.Results Genotypes reported by the GMEX system showed 100%agreement with those determined by using the YZY Kit and Sanger sequencing for all three CYP2C19 alleles(*2,*3 and*17)tested.The average result’s turnaround times for the GMEX and YZY Kit methods were 85.0(IQR:85.0-86.0)and 1630.0(IQR:354.0-7594.0)min(p<0.001),respectively.Conclusions Our data suggest that the GMEX system is a reliable and feasible point-of care system for rapid CYP2C19 genotyping for the CHANCE-2 trial or related clinical and research applications.Xia Meng Anxin Wang Guojun Zhang Siying Niu Wei Li Sifei Han Fang Fang Xingquan Zhao Kehui Dong Zening Jin Huaguang Zheng Kelin Chen Hao Li Chengyuan Yang Yongjun Wang 2021Stroke & Vascular Neurology2021,6,2:7
11Gastrointestinal bleeding during acute ischaemic stroke hospitalisation increases the risk of stroke recurrence显示文摘Objective Gastrointestinal(GI)bleeding in patients who had a stroke is strongly associated with a higher risk of death and loss of independence.However,it is unknown whether GI bleeding increases risk for recurrence of stroke.In this study,we assess the potential relationship between GI bleeding and stroke recurrence in patients within 12 months of an acute ischaemic stroke(AIS),using the China National Stroke Registry(CNSR).Methods This study included 22216 patients who had an ischaemic stroke included in the CNSR from 2007 to 2008.We analysed baseline patient characteristics,GI bleeding and outcomes of patients who had an AIS,specifically stroke recurrence at 3,6 and 12 months.We used multivariable logistic regression to evaluate a possible association between GI bleeding and stroke recurrence.results Of the 12415 patients included in our study,12.3%,15.5%and 17.7%had a stroke recurrence at 3,6 and 12 months,respectively.GI bleeding was an independent stroke recurrence risk factor in patients after ischaemic stroke at 3 months(adjusted OR 1.481,95%CI 1.118 to 1.962),6 months(adjusted OR 1.448,95%CI 1.106 to 1.896)and 12 months(adjusted OR 1.350;95%CI 1.034 to 1.763).Conclusion GI bleeding was associated with the increased risk of stroke recurrence after an AIS.Wanliang Du Xingquan Zhao Yilong Wang Yuesong Pan Gaifen Liu Anxin Wang Ruijun Ji Liping Liu Hongqiu Gu Kehui Dong Penglian Wang Yongjun Wang 2020Stroke & Vascular Neurology2020,5,2:7
12Estimating significant wave height from SAR imagery based on an SVM regression model显示文摘A new method for estimating significant wave height(SWH) from advanced synthetic aperture radar(ASAR) wave mode data based on a support vector machine(SVM) regression model is presented. The model is established based on a nonlinear relationship between σ0, the variance of the normalized SAR image, SAR image spectrum spectral decomposition parameters and ocean wave SWH. The feature parameters of the SAR images are the input parameters of the SVM regression model, and the SWH provided by the European Centre for Medium-range Weather Forecasts(ECMWF) is the output parameter. On the basis of ASAR matching data set, a particle swarm optimization(PSO) algorithm is used to optimize the input kernel parameters of the SVM regression model and to establish the SVM model. The SWH estimation results yielded by this model are compared with the ECMWF reanalysis data and the buoy data. The RMSE values of the SWH are 0.34 and 0.48 m, and the correlation coefficient is 0.94 and 0.81, respectively. The results show that the SVM regression model is an effective method for estimating the SWH from the SAR data. The advantage of this model is that SAR data may serve as an independent data source for retrieving the SWH, which can avoid the complicated solution process associated with wave spectra.GAO Dong LIU Yongxin MENG Junmin JIA Yongjun FAN Chenqing 2018Acta Oceanologica Sinica2018,37,3:7
13Benefit Evaluation of the Deep Peak-regulation Market in the Northeast China Grid显示文摘In the Northeast China Grid(NCG),the percentage of wind power has reached nearly 20%of the total installed generation capacity,which causes increasing demands for deep peak-regulation capacity(DPC)during the operation of power systems.The shortage of DPC has become a significant problem in the NCG which may lead to wind curtailments and affect the security of power systems as well as the heating needs for inhabitants.In order to cope with this DPC shortage issue,the deep peak-regulation market(DPM)was established and has been running steadily in the past few years in NCG.This paper elaborates on the roles of the market players and the operational processes of the DPM,of which the advancements in terms of management mechanism are summarized.Moreover,benefits of the DPM for social harmony,environmental protection and economic efficiency are analyzed,for which relevant evaluation indices are proposed.A five-unit simulation system is constructed to illustrate the operation and benefits of the DPM.And focusing on comparisons with the previous Two Rules,the case study of Liaoning Power Grid verifies further that the DPM is feasible and able to bring more benefits to grids.Hongyan Ma Zheng Yan Mingjie Li Dong Han Xiao Han Yiqun Song Ping Wei Gang Li Yongjun Liu 2019CSEE Journal of Power and Energy Systems2019,5,4:6
14Emerging role of natural products in cancer immunotherapy显示文摘Cancer immunotherapy has become a new generation of anti-tumor treatment,but its indications still focus on several types of tumors that are sensitive to the immune system.Therefore,effective strategies that can expand its indications and enhance its efficiency become the key element for the further development of cancer immunotherapy.Natural products are reported to have this effect on cancer immunotherapy,including cancer vaccines,immune-check points inhibitors,and adoptive immune-cells therapy.And the mechanism of that is mainly attributed to the remodeling of the tumorimmunosuppressive microenvironment,which is the key factor that assists tumor to avoid the recognition and attack from immune system and cancer immunotherapy.Therefore,this review summarizes and concludes the natural products that reportedly improve cancer immunotherapy and investigates the mechanism.And we found that saponins,polysaccharides,and flavonoids are mainly three categories of natural products,which reflected significant effects combined with cancer immunotherapy through reversing the tumor-immunosuppressive microenvironment.Besides,this review also collected the studies about nano-technology used to improve the disadvantages of natural products.All of these studies showed the great potential of natural products in cancer immunotherapy.Songtao Dong Xiangnan Guo Fei Han Zhonggui He Yongjun Wang 2022Acta Pharmaceutica Sinica B2022,12,3:5
15The efficacy and safety of nimodipine in acute ischemic stroke patients with mild cognitive impairment: a double-blind, randomized,placebo-controlled trial显示文摘Nimodipine might be effective in subcortical vascular dementia(VaD). Its benefit in preventing further cognitive decline in patients with acute ischemic stroke(AIS) and vascular mild cognitive impairment(VaMCI) remains to be established. In this multicenter, double-blind trial, we randomly assigned 654 eligible patients to nimodipine 30 mg three times a day or placebo. The primary outcome was any cognitive decline defined by the changes on the Mini-Mental State Examination(DMMSE à3) or vascular AD assessment scale cognitive subscale(DADAS-cog ! 4) at 6 months. Secondary outcomes included any distribution shift of DADAS-cog, DMMSE or cognitive improvement defined by DADAS-cog à2, or DMMSE ! 0. The primary outcome in the nimodipine group and placebo group were similar for DMMSE à3(4.18% and 7.22%, respectively, P = 0.15) and DADAS-cog ! 4(8.36% and 8.93% respectively,P = 0.88). The distribution shift of DADAS-cog and DMMSE differed significantly between the two groups(P = 0.03 and P = 0.05 respectively). Cognitive improvement occurred in 55.4% in the nimodipine group and 43.6% in the placebo group measured by DADAS-cog à2(Odds Ratio, 1.54; 95% confidence interval[CI] 1.10–2.14, P < 0.01) or 84.0% and 74.6% respectively by DMMSE ! 0(Odds Ratio, 1.79; 95% CI 1.18–2.70, P < 0.01). Nimodipine was associated with better cognitive function in the memory domain. The adverse events rate was similar in two groups. This study is registered with ClinicalTrials.gov,NCT01220622. Nimodipine did not show benefit to prevent cognitive decline in AIS patients with VaMCI, but improved cognition moderately, especially measured in the memory domain.Huaguang Zheng Yilong Wang Anxin Wang Hao Li David Wang Xingquan Zhao Penglian Wang Haipeng Shen Lijun Zuo Yuesong Pan Zixiao Li Xia Meng Xianwei Wang Weixiong Shi Yi Ju Liping Liu Kehui Dong Chunxue Wang Rubo Sui Rong Xue Xiaoping Pan Xiaoyua Niu Benyan Luo Yi Sui Huali Wang Tao Feng Yongjun Wang 2019Science Bulletin2019,64,2:5
16Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC.Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 2022Hepatobiliary Surgery and Nutrition2022,11,2:4
17Can semipermeable membranes coating materials influence in vivo performance for paliperidone tri-layer ascending release osmotic pump tablet:In vitro evaluation and in vivo pharmacokinetics study显示文摘One purpose of this study was to develop a paliperidone(PAL)tri-layer ascending release pushepull osmotic pump(TA-PPOP)tablet which could meet the needs of clinical applications.And another purpose was to investigate whether different coating materials influenced in vivo performance of TA-PPOP.The ascending release mechanism of this trilayer delivery system on theory was elaborated.TA-PPOP was prepared by means of coating with cellulose acetate(CA)or ethyl cellulose(EC).Several important influence factors such as different core tablet compositions and different coating solution ingredients involved in the formulation procedure were investigated.The optimization of formulation and process was conducted by comparing different in vitro release behaviors of PAL.In vitro dissolution studies indicated that both the two formulations of different coating materials were able to deliver PAL at an ascending release rate during the whole 24 h test.The in vivo pharmacokinetics study showed that both self-made PPOP tablets with different coating had a good in vitro-in vivo correlation(IVIVC)and were bioequivalent with the brand product,which demonstrated no significant influence of the coating materials on the in vivo release acceleration of TA-PPOP.Guangjing Li Yongjun Wang Hongming Chen Donglei Leng Panqin Ma Yanjie Dong Lifang Gao Zhonggui He 2015Asian Journal of Pharmaceutical Sciences2015,10,2:4
18Who may benefit from lower dosages of intravenous tissue plasminogen activator? Results from a cluster data analysis显示文摘background The risk of symptomatic intracranial haemorrhage(sICH)after thrombolysis is low but severe.Lower dose of alteplase may reduce the risk of sICH.We aim to identify subsets of patients who could benefit from lower dose of alteplase compared with standard dose.Methods Data from two observational registries were pooled together.A total of 3479 patients who had acute ischaemic stroke were entered into the interaction tree model.The response variable was the rate of sICH per the definition of the National Institute of Neurological Disorders and Stroke Study.Clinical improvement was measured by the National Institutes of Health Stroke Scale(NIHSS)and defined as NIHSS 0 or 1 or an improvement of more than 4 points(within 7 days or at discharge).Rare event logistic regression was performed to analyse the OR of safety outcome.results To optimise the interaction effect between tissue plasminogen activator(tPA)dosage(standard/lower)and patient subgroups,three subgroups based on the severity of stroke were identified:(1)NIHSS≤4,(2)NIHSS between 5 and 14,and(3)NIHSS≥15.The estimated difference of OR of having sICH was 2.71(95%CI 0.80 to 7.69,p=0.10)for mild,0.13(95%CI 0.02 to 0.68,p=0.01)for moderate,and 0.65(95%CI 0.19 to 2.55,p=0.52)for severe,respectively.In addition,patients who had moderate stroke treated with lower dose had comparable efficacy outcome(OR 1.23,95%CI 0.71 to 2.13,p=0.45).Conclusion Our analysis demonstrated that in patients who had moderate stroke,lower doses of alteplase are associated with significant sICH reduction and non-inferior performance in efficacy,compared with those in the standard dose group.Yi Dong Ye Han Haipeng Shen Yilong Wang Frank Ma Hao Li Yongjun Wang Qiang Dong 2020Stroke & Vascular Neurology2020,5,4:3
19Origin and Source of Deep Natural Gas in Nanpu sag, Bohai Bay Basin, China显示文摘Natural gas exploration in Nanpu sag, Bohai Bay Basin, has achieved breakthroughs in recent years, and a number of natural gas and condensate wells with high yield have been found in several structures in the beach area. Daily gas production of single wells is up to 170,000 m3, and high-yield wells are mainly distributed in?the Nanpu No. 1 structural belt.?Studies have shown that these natural gases are mainly hydrocarbon gases, with methane content about 80% to 90% and ethane 6%-9%, so they are mainly wet gas; and non-hydrocarbons are at a low level.?Carbon isotopes of methane range from -42‰ to -36‰, and ethane from -28‰ to -26‰. Calculated maturity based on the relationship between δ13C and Ro of natural gas, the gases are equivalent to those generated from organic matter when Ro is 1.0%-1.7% (mainly 1.25%-1.32%). The natural gas is oil-type gas generated from the source rocks at mature to high mature stage, associated with condensate, so carbon isotopes of the gases are heavier. Natural gas in the Nanpu No.1 structural belt is mainly associated gas with condensate. The analysis of the origin and source of natural gas and condensate, combined with the monomer hydrocarbon carbon isotopes and biomarker, indicated that the main source rocks in the Nanpu No.1 structural belt were Es3 (the lower member of the Shahejie Formation), followed by Es1 (the upper member of the Shahejie Formation).?The high-mature hydrocarbons from source rocks in the deep sag mainly migrated through deep inherited faults into shallow traps and accumulated to form oil and gas pools. Therefore, there is a great potential for exploring gas in deep layers.ZHU Guangyou WANG Zhengjun WANG Yongjun ZHAO Jie DONG Yuexia WANG Kai LIU Yongchang WANG Jianwei 2013Acta Geologica Sinica(English Edition)2013,87,4:3
