2China Stroke Statistics 2019:A Report From the National Center for Healthcare Quality Management in Neurological Diseases,China National Clinical Research Center for Neurological Diseases,the Chinese Stroke Association,National Center for Chronic and Non-communicable Disease Control and Prevention,Chinese Center for Disease Control and Prevention and Institute for Global Neuroscience and Stroke Collaborations显示文摘China faces the greatest challenge from stroke in the world.The death rate for cerebrovascular diseases in China was 149.49 per 100000,accounting for 1.57 million deaths in 2018.It ranked third among the leading causes of death behind malignant tumours and heart disease.The age-standardised prevalence and incidence of stroke in 2013 were 1114.8 per 100000 population and 246.8 per 100000 person-years,respectively.According to the Global Burden of Disease Study 2017,the years of life lost(YLLs)per 100000 population for stroke increased by 14.6%;YLLs due to stroke rose from third highest among all causes in 1990 to the highest in 2017.The absolute numbers and rates per 100000 population for all-age disability-adjusted life years(DALYs)for stroke increased substantially between 1990 and 2017,and stroke was the leading cause of all-age DALYs in 2017.The main contributors to cerebrovascular diseases include behavioural risk factors(smoking and alcohol use)and pre-existing conditions(hypertension,diabetes mellitus,dyslipidaemia and atrial fibrillation(AF)).The most prevalent risk factors among stroke survivors were hypertension(63.0%-84.2%)and smoking(31.7%-47.6%).The least prevalent was AF(2.7%-7.4%).The prevalences for major risk factors for stroke are high and most have increased over time.Based on the latest national epidemiological data,26.6%of adults aged≥15 years(307.6 million adults)smoked tobacco products.For those aged≥18 years,age-adjusted prevalence of hypertension was 25.2%;adjusted prevalence of hypercholesterolaemia was 5.8%;and the standardised prevalence of diabetes was 10.9%.For those aged≥40 years,the standardised prevalence of AF was 2.31%.Data from the Hospital Quality Monitoring System showed that 3010204 inpatients with stroke were admitted to 1853 tertiary care hospitals during 2018.Of those,2466785(81.9%)were ischaemic strokes(ISs);447609(14.9%)were intracerebral haemorrhages(ICHs);and 95810(3.2%)were subarachnoid haemorrhages(SAHs).The average age of patients admitted was 66 years old,and nearly 60%were male.A total of 1555(0.1%),2774(0.6%)and 1347(1.4%)paediatric strokes(age<18 years)were identified among IS,ICH and SAH,respectively.Over one-third(1063892(35.3%))of the patients were covered by urban resident basic medical insurance,followed by urban employee basic medical insurance(699513(23.2%))and new rural cooperative medical schema(489361(16.3%)).The leading risk factor was hypertension(67.4%for IS,77.2%for ICH and 49.1%for SAH),and the leading comorbidity was pneumonia or pulmonary infection(10.1%for IS,31.4%for ICH and 25.2%for SAH).In-hospital death/discharge against medical advice rate was 8.3%for stroke inpatients,ranging from 5.8%for IS to 19.5%for ICH.The median and IQR of length of stay was 10.0(7.0-14.0)days,ranging from 10.0(7.0-13.0)in IS to 14.0(8.0-22.0)in SAH.Data from the Chinese Stroke Center Alliance demonstrated that the composite scores of guideline-recommended key performance indicators for patients with IS,ICH and SAH were 0.77±0.21,0.72±0.28 and 0.59±0.32,respectively.Yong-Jun Wang Zi-Xiao Li Hong-Qiu Gu Yi Zhai Yong Jiang Xing-Quan Zhao Yi-Long Wang Xin Yang Chun-Juan Wang Xia Meng Hao Li Li-Ping Liu Jing Jing Jing Wu An-Ding Xu Qiang Dong David Wang Ji-Zong Zhao On behalf of China Stroke Statistics 2019 Writing Committee 2020Stroke & Vascular Neurology2020,5,3:181
3Current status of severe fever with thrombocytopenia syndrome in China显示文摘Severe fever with thrombocytopenia syndrome(SFTS) is an emerging infectious disease caused by SFTS virus(SFTSV). SFTSV is associated with a high mortality rate and has been reported in China, South Korea and Japan. SFTSV undergoes rapid changes owing to evolution, gene mutations, and reassortment between different strains of SFTSV. In this review, we summarize the recent cases and general properties of SFTS, focusing on the epidemiology, genetic diversity,clinical features, and diagnostics of SFTSV in China. From 2010 to October 2016, SFTS cases were reported in 23 provinces of China, with increased numbers yearly. Infection and death cases are mainly found in central China, where the Haemaphysalis longicornis ticks are spread. The national average mortality rate of SFTS infection was 5.3%, with higher risk to elder people. The main epidemic period was from May to July, with a peak in May. Thus, SFTS reminds a significant public health problem, and development of prophylactic vaccines and effective antiviral drugs will be highly needed.Jianbo Zhan Qin Wang Jing Cheng Bing Hu Jing Li Faxian Zhan Yi Song Deyin Guo 2017Virologica Sinica2017,32,1:71
4Efficacy and safety of bevacizumab plus chemotherapy in Chinese patients with metastatic colorectal cancer:a randomized phase Ⅲ ARTIST trial显示文摘The efficacy and safety of bevacizumab with modified irinotecan,leucovorin bolus,and 5-fluorouracil intravenous infusion(mIFL) in the first-line treatment of metastatic colorectal cancer(mCRC) has not been well evaluated in randomized clinical trials in Chinese patients.We conducted a phrase Ⅲ trial in which patients with previously untreated mCRC were randomized 2:1 to the mIFL [irinotecan(125 mg/m2),leucovorin(20 mg/m2) bolus,and 5-fluorouracil intravenous infusion(500 mg/m2) weekly for four weeks every six weeks] plus bevacizumab(5 mg/kg every two weeks) group and the mIFL group,respectively.Co-primary objectives were progression-free survival(PFS) and 6-month PFS rate.In total,214 patients were enrolled.Our results showed that addition of bevacizumab to mIFL significantly improved median PFS(4.2 months in the mIFL group vs.8.3 months in the bevacizumab plus mIFL group,P < 0.001),6-month PFS rate(25.0% vs.62.6%,P < 0.001),median overall survival(13.4 months vs.18.7 months,P = 0.014),and response rate(17% vs.35%,P = 0.013).Grades 3 and 4 adverse events included diarrhea(21% in the mIFL group and 26% in the bevacizumab plus mIFL group) and neutropenia(19% in the mIFL group and 33% in the bevacizumab plus mIFL group).No wound-healing complications or congestive heart failure occurred.Our results suggested that bevacizumab plus mIFL is effective and well tolerated as first-line treatment for Chinese patients with mCRC.Clinical benefit and safety profiles were consistent with those observed in pivotal phase Ⅲ trials with mainly Caucasian patients.Zhong-Zhen Guan Jian-Ming Xu Rong-Cheng Luo Feng-Yi Feng Li-Wei Wang Lin Shen Shi-Ying Yu Yi Ba Jun Liang Dong Wang Shu-Kui Qin Jie-Jun Wang Jing He Chuan Qi Rui-Hua Xu 2011Chinese Journal of Cancer2011,30,10:48
5Prognostic factors of refractory NSCLC patients receiving anlotinib hydrochloride as the third-or further-line treatment显示文摘Objective:Anlotinib hydrochloride is a multitarget tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor,fibroblast growth factor receptor,platelet-derived growth factor receptor,c-Kit,and c-MET;therefore,it exhibits both antitumor and anti-angiogenetic activities.A phase III trial has shown that anlotinib improved progression-free survival(PFS)and overall survival(OS)in patients with advanced non-small cell lung cancer(NSCLC),who presented with progressive disease or intolerance after standard chemotherapy.This study aimed to analyze the characteristics of patients receiving anlotinib treatment to determine the dominant populations who are fit for the treatment.Methods:Data were collected from March 2015 to January 2017 from a randomized,double-blind,placebo-controlled,multicenter,phase III trial of anlotinib(ALTER0303).A total of 437 patients were enrolled and randomly allocated(2:1)to the anlotinib and placebo groups.Kaplan–Meier analysis and log-rank test were performed to compare PFS and OS.Cox proportional hazards model was adopted for multivariate prognostic analysis.Results:Multivariate analysis indicated that high post-therapeutic peripheral blood granulocyte/lymphocyte ratio and elevated alkaline phosphatase levels were independent risk factors for PFS.Meanwhile,elevated thyroid-stimulating hormone,blood glucose,and triglyceride levels;hypertension;and hand–foot syndrome were independent protective factors of PFS.High posttherapeutic peripheral blood granulocyte/lymphocyte ratio,an Eastern Cooperative Oncology Group(ECOG)score≥2,and the sum of the maximal target lesion length at baseline were independent risk factors of OS,and hypertriglyceridemia was an independent protective factor of OS.Conclusions:This study preliminarily explored the possible factors that affected PFS and OS after anlotinib treatment in patients with advanced refractory NSCLC,and the baseline characteristics of the therapeutically dominant populations were then identified.Jing Wang Yizhuo Zhao Qiming Wang Li Zhang Jianhua Shi Zhehai Wang Ying Cheng Jianxing He Yuankai Shi Hao Yu Yang Zhao Weiqiang Chen Yi Luo Xiuwen Wang Kejun Nan Faguang Jin Jian Dong Baolan Li Zhujun Liu Baohui Han Kai Li 2018Cancer Biology & Medicine2018,15,4:46
6Effect of in-hospital medical complications on case fatality post-acute ischemic stroke: data from the China National Stroke Registry显示文摘WANG Peng-lian ZHAO Xing-quan YANG Zhong-hua WANG An-xin WANG Chun-xue LIU Li-ping WANGYi-long WANG Xin-gao JU Yi CHEN Sheng-yun CHEN Qi-dong QU Hui LU Jing-jing ZHANG Jing MA Rui-hua ZHANG Yu-mei WANG Yong-jun 2012Chinese Medical Journal2012,,14:37
7Prevalence and evolution of drug resistance HIV-1 variants in Henan, China显示文摘To understand the prevalence and evolution of drug resistant HIV strains in Henan China after the implementation of free antiretroviral therapy for AIDS patients. 45 drug nave AIDS patients, 118 AIDS patients who received three months antiretroviral therapy and 124 AIDS patients who received six months antiretroviral treatment were recruited in the southern part of Henan province. Information on general condition, antiretroviral medicines, adherence and clinical syndromes were collected by face to face interview. Meanwhile, 14ml EDTA anticoagulant blood was drawn. CD4/CD8 T cell count, viral load and genotypic drug resistance were tested. The rates of clinical improvement were 55.1% and 50.8% respectively three months and six months after antiretroviral therapy. The mean CD4 cell count after antiretroviral therapy was significantly higher than in drug nave patients. The prevalence rate of drug resistant HIV strains were 13. 9%, 45.4% and 62.7% in drug nave patients, three month treatment patients and six month treatment patients, respectively. The number of resistance mutation codons and the frequency of mutations increased significantly with continued antiretroviral therapy. The mutation sites were primarily at the 103, 106 and 215 codons in the three-month treatment group and they increased to 15 codon mutations in the six-month treatment group. From this result, the evolution of drug resistant strains was inferred to begin with the high level NNRTI resistant strain, and then develop low level resistant strains to NRTIs. The HIV strains with high level resistance to NVP and low level resistance to AZT and DDI were highly prevalent because of the AZT+DDI+NVP combination therapy. These HIV strains were also cross resistant to DLV, EFV, DDC and D4T. Poor adherence to therapy was believed to be the main reason for the emergence and prevalence of drug resistant HIV strains. The prevalence of drug resistant HIV strains was increased with the continu- ation of antiretroviral therapy in the southern part of Henan province. Measures, that could promote high level adherence, provide new drugs and change ART regimens in failing patients, should be implemented as soon as possible.Jing Yun LI Han Ping LI Lin LI Hong LI Zhe WANG Kun YANG Zuo Yi BAO Dao Min ZHUANG Si Yang LIU Yong Jian LIU Hui XING Yi Ming SHAO 2005Cell Research2005,15,11:34
8Crust-mantle coupling in North China:Preliminary analysis from seismic anisotropy显示文摘Data from the CASN(Capital Area Seismograph Network),NSNC(National Seismograph Network of China),and IRIS(Incorporated Research Institutions for Seismology) are compared with data from a temporary North China Seismic Array to obtain the background orientation of the horizontal crustal principal compressive stress at NE 95.1°±15.4° in North China.Data are corrected for disturbances of faults and irregular tectonics,and are used to constrain the fast SKS polarization at NE 110.2°±15.8° in North China.Individual station analyses suggests that there is consistently more than 10° difference between the polarizations of fast shear-wave in the crust and those of fast SKS phases.Azimuthally anisotropic phase velocities of Rayleigh waves at different periods also indicate an orientation change for fast velocity with depth.It suggests the crust-mantle coupling in North China follows neither the simple decoupling model nor the strong coupling model.Instead,it is possibly some inhomogeneous combination of two models or some gradual-change model of physical characteristics.This study shows that anisotropy in the crust and mantle could be multiply characterized more correctly and crust-mantle coupling could be analyzed further,if increasing near-field shear-wave splitting data that indicate crustal anisotropy,combined with the azimuthal anisotropy of Rayleigh waves,besides the result of SKS splitting travelling through lithosphere and surface GPS measurements.GAO Yuan WU Jing YI GuiXi SHI YuTao 2010Chinese Science Bulletin2010,55,31:34
9Analysis of factors associated with disease outcomes in hospitalized patients with 2019 novel coronavirus disease显示文摘Background Since early December 2019,the 2019 novel coronavirus disease(COVID-19)has caused pneumonia epidemic in Wuhan,Hubei province of China.This study aimed to investigate the factors affecting the progression of pneumonia in COVID-19 patients.Associated results will be used to evaluate the prognosis and to find the optimal treatment regimens for COVID-19 pneumonia.Methods Patients tested positive for the COVID-19 based on nucleic acid detection were included in this study.Patients were admitted to 3 tertiary hospitals in Wuhan between December 30,2019,and January 15,2020.Individual data,laboratory indices,imaging characteristics,and clinical data were collected,and statistical analysis was performed.Based on clinical typing results,the patients were divided into a progression group or an improvement/stabilization group.Continuous variables were analyzed using independent samples t-test or Mann-Whitney U test.Categorical variables were analyzed using Chi-squared test or Fisher’s exact test.Logistic regression analysis was performed to explore the risk factors for disease progression.Results Seventy-eight patients with COVID-19-induced pneumonia met the inclusion criteria and were included in this study.Efficacy evaluation at 2 weeks after hospitalization indicated that 11 patients(14.1%)had deteriorated,and 67 patients(85.9%)had improved/stabilized.The patients in the progression group were significantly older than those in the disease improvement/stabilization group(66[51,70]vs.37[32,41]years,U=4.932,P=0.001).The progression group had a significantly higher proportion of patients with a history of smoking than the improvement/stabilization group(27.3%vs.3.0%,χ^2=9.291,P=0.018).For all the 78 patients,fever was the most common initial symptom,and the maximum body temperature at admission was significantly higher in the progression group than in the improvement/stabilization group(38.2[37.8,38.6]vs.37.5[37.0,38.4]°C,U=2.057,P=0.027).Moreover,the proportion of patients with respiratory failure(54.5%vs.20.9%,χ^2=5.611,P=0.028)and respiratory rate(34[18,48]vs.24[16,60]breaths/min,U=4.030,P=0.004)were significantly higher in the progression group than in the improvement/stabilization group.C-reactive protein was significantly elevated in the progression group compared to the improvement/stabilization group(38.9[14.3,64.8]vs.10.6[1.9,33.1]mg/L,U=1.315,P=0.024).Albumin was significantly lower in the progression group than in the improvement/stabilization group(36.62±6.60 vs.41.27±4.55 g/L,U=2.843,P=0.006).Patients in the progression group were more likely to receive high-level respiratory support than in the improvement/stabilization group(χ^2=16.01,P=0.001).Multivariate logistic analysis indicated that age(odds ratio[OR],8.546;95%confidence interval[CI]:1.628-44.864;P=0.011),history of smoking(OR,14.285;95%CI:1.577-25.000;P=0.018),maximum body temperature at admission(OR,8.999;95%CI:1.036-78.147,P=0.046),respiratory failure(OR,8.772,95%CI:1.942-40.000;P=0.016),albumin(OR,7.353,95%CI:1.098-50.000;P=0.003),and C-reactive protein(OR,10.530;95%CI:1.224-34.701,P=0.028)were risk factors for disease progression.Conclusions Several factors that led to the progression of COVID-19 pneumonia were identified,including age,history of smoking,maximum body temperature at admission,respiratory failure,albumin,and C-reactive protein.These results can be used to further enhance the ability of management of COVID-19 pneumonia.Wei Liu Zhao-Wu Tao Lei Wang Ming-Li Yuan Kui Liu Ling Zhou Shuang Wei Yan Deng Jing Liu Hui-Guo Liu Ming Yang Yi Hu 2020Chinese Medical Journal2020,,9:31
10Study on Multi-Scale Blending Initial Condition Perturbations for a Regional Ensemble Prediction System显示文摘An initial conditions(ICs) perturbation method was developed with the aim to improve an operational regional ensemble prediction system(REPS). Three issues were identified and investigated:(1) the impacts of perturbation scale on the ensemble spread and forecast skill of the REPS;(2) the scale characteristic of the IC perturbations of the REPS; and(3) whether the REPS's skill could be improved by adding large-scale information to the IC perturbations. Numerical experiments were conducted to reveal the impact of perturbation scale on the ensemble spread and forecast skill. The scales of IC perturbations from the REPS and an operational global ensemble prediction system(GEPS) were analyzed. A 'multi-scale blending'(MSB) IC perturbation scheme was developed, and the main findings can be summarized as follows: The growth rates of the ensemble spread of the REPS are sensitive to the scale of the IC perturbations; the ensemble forecast skills can benefit from large-scale perturbations; the global ensemble IC perturbations exhibit more power at larger scales, while the regional ensemble IC perturbations contain more power at smaller scales; the MSB method can generate IC perturbations by combining the small-scale component from the REPS and the large-scale component from the GEPS; the energy norm growth of the MSB-generated perturbations can be appropriate at all forecast lead times; and the MSB-based REPS shows higher skill than the original system, as determined by ensemble forecast verification.ZHANG Hanbin CHEN Jing ZHI Xiefei WANG Yi WANG Yanan 2015Advances in Atmospheric Sciences2015,32,8:29

13Gene expression alteration during redox-dependent enhancement of arsenic cytotoxicity by emodin in HeLa cells显示文摘Emodin (1,3,8-trihydroxy-6-methylanthraquinone) could enhance the sensitivity of tumor cells to arsenic trioxide(As2O3)–induced apoptosis via generation of ROS, but the molecular mechanism has not been elucidated. Here, wecarried out cDNA microarray-based global transcription profiling of HeLa cells in response to As2O3/emodin cotreatment,comparing with As2O3–only treatment. The results showed that the expression of a number of genes was substantiallyaltered at two time points. These genes are involved in different aspects of cell function. In addition to redox regulationand apoptosis, ROS affect genes encoding proteins associated with cell signaling, organelle functions, cell cycle,cytoskeleton, etc. These data suggest that based on the cytotoxicity of As2O3, emodin mobilize every genomic resourcethrough which the As2O3–induced apoptosis is facilitated.Xiao Jing WANG Jie YANG Hui CANG Yan Qiong ZOU Jing YI 2005Cell Research2005,15,7:28
14A reversed CD4/CD8 ratio of tumor-infiltrating lymphocytes and a high percentage of CD4^(+)FOXP3^(+) regulatory T cells are significantly associated with clinical outcome in squamous cell carcinoma of the cervix显示文摘In this study,40 biopsy samples collected from cervical cancer patients at the First Affiliated Hospital of Xi’an Jiaotong University,China,were retrospectively assessed using immunohistochemistry for CD4^(+) and CD8^(+) tumor-infiltrating lymphocytes(TILs)and were analyzed for the expression of FOXP3,OX40,granzyme B(GrB)and perforin(Prf).The proliferating index of the TILs was determined by assessing Ki67 expression.We determined the prognostic value of low and high numbers of TILs on survival by performing Kaplan–Meier analysis using median values as the cut-off points.Except for the number of CD4^(+)FOXP3^(+) regulatory T cells(Tregs)and the CD4/CD8 ratio,none of the CD4^(+),CD8^(+),OX401,GrB^(+) or Prf^(+) TILs were associated with the overall 5-year survival rate.The 5-year survival rate was significantly lower in patients who had a high percentage of Tregs as compared with the those who had a lower percentage(35.3%versus 88.9%,P50.001),while the 5-year survival rate was significantly higher in patients with a high CD4/CD8 ratio as compared with patients who had a low CD4/CD8 ratio(82.4%versus 44.4%,P50.029).When we considered the deaths and surviving cases as separate groups,we found that both the number of CD4^(+) T cells and the CD4/CD8 ratio were significantly lower in patients who died as compared with those who survived(26.33±11.80 versus 47.79±38.18,P=0.023 and 0.60±0.25 versus 1.17±1.02,P=0.019,respectively).In conclusion,decreased proportions of tumor-infiltrating CD4^(+) T cells with high percentages of Tregs and reversed CD4/CD8 ratios were significantly associated with the clinical outcome of patients with cervical carcinoma.Walayat Shah Xiaofei Yan Li Jing Yi Zhou Hongwei Chen Yili Wang 2011Cellular & Molecular Immunology2011,8,1:24
15Mechanisms of aid-leaching reagent calcium fluoride in the extracting vanadium processes from stone coal显示文摘The mechanisms of aid-leaching reagent calcium fluoride in the extracting vanadium processes were researched by comparing the blank extraction with the extraction with calcium fluoride as aid-leaching reagent. The leaching experiments were carried out under the conditions of 95 ℃, 6h, 1.5 mlg-1 , 15 vol % H2SO4 , and 5 % calcium fluoride (mass ratio of CaF2 to stone coal). The concentrations of hydrogen ion were adjusted from initial 1.82 and 4.79 mol L -1 to the pH of 1.80 ± 0.05 by 200 g L-1 lime milk, respectively. The solvent extraction experiments were carried out under the organic phase using 15 vol% D2EHPA, 5 vol% TBP, and 80 vol% sulfonated kerosene and O/A phase ratio of 1/4. The leaching rate of vanadium and six-stage countercurrent solvent extraction rate of vanadium can be remarkably improved from 66.71 to 92.97 % and 81.15 to 98.81 %, respectively, when calcium fluoride was added as aid-leaching reagent. In the leaching process, fluorine can enhance the breakage of the structure of vanadium-bearing minerals. Meanwhile, fluoride ion can combine with iron ion to generate acid-insoluble iron fluoride hydrate (Fe2F57H2O) and consume all ferric ions and a portion of ferrous ions. In adjusting pH value process, the massive impurities are decreased to form KAlSO4 and FeAlF5 . In solvent extraction process, fluorine can prevent the formation of ferric hydroxide colloids and eliminate the formed unstable ferric hydroxide colloids and the silicon-containing colloids to promote the sufficient contact between the aqueous phase and the organic phase and the sufficient reaction.Fei Wang Yi-Min Zhang Jing Huang Tao Liu Yi Wang Xiao Yang Jie Zhao 2013Rare Metals2013,32,1:22
16Charlson comorbidity index helps predict the risk of mortality for patients with type 2 diabetic nephropathy显示文摘研究目的:探讨Charlson合并症指数(CCI)对2型糖尿病肾病死亡率的预测作用。研究方法:建立2型糖尿病肾病研究队列,根据CCI评分将患者合并症的严重程度分为三度:轻度(CCI1–2分)、中度(CCI 3–4分)、重度(CCI≥5分)。将影响死亡率的因素及按CCI分层后的组间差异指标进行Logistic回归分析及方差分析(ANOVA)。Kaplan-Meier生存曲线分析CCI指数对生存时间及死亡率的影响。重要结论:533例2型糖尿病肾病患者纳入研究。所有患者的CCI评分均大于1,44.7%(238/533)的患者死亡。患者的死亡率随CCI评分增加而增加,CCI 1–2分患者的死亡率为21.0%(50/238),CCI 3–4分患者的死亡率为56.7%(135/238),CCI≥5分患者的死亡率为22.3%(53/238)。Logistic回归分析显示CCI评分、血红蛋白和血浆白蛋白水平是患者死亡率的预测因子(P<0.05)。方差分析结果显示,与CCI评分相对较低的患者相比,CCI评分越高的患者其血红蛋白水平较低,而血清肌酐较高,死亡率也更高。Kaplan-Meier生存曲线显示CCI评分越高的患者生存时间越短。CCI评分是一种简单易行且实用的评估疾病合并症的方法,可用于预测2型糖尿病肾病患者的死亡率。关注2型糖尿病肾病患者的合并症将有利于早期、有效治疗及改善预后。You-qun HUANG Rong GOU Yong-shu DIAO Qing-hua YIN Wen-xing FAN Ya-ping LIANG Yi CHEN Min WU Li ZANG Ling LI Jing ZANG Lu CHENG Ping FU Fang LIU 2014Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2014,15,1:23

Then quorum sensing inhibition(QSI) activities of these compounds were tested using Chromobacterium violaceum CV026 as the bioindicator strain. The antitumor activities of these compounds were measured using SGC7901 as cell proliferation and cytotoxicity. Resultsα-Spinasteryl-β-D-glucopyranoside(1), stigmasta-7,22-diene-3-O-[α-L-arabinopyranosyl(1→2)]-β-D-galactopyranoside(2), kaempferol 3-O-[2-O-(trans-p-coumaroyl)-3-O-α-D-glucopyranosyl]-α-D-glucopyranoside(3), aromadendrin(4), catechin(5), phlorizin 4′-O-β-D-glucopyranoside(6),(3R,6R,7E)-3-hydroxy-4,7-megastigmadien-9-one(7), dodecanoic acid(8), 3β-acetoxy-20-lupanol(9), and 3β,6α,13β-trihydroxyolean- 7-one(10) were successively isolated from the leaves of C. nitidissima. Unfortunately, these compounds had no QSI activity. Based on Cell Counting Kit-8(CCK-8) assay, compound 10 showed the best anti-tumor activity of all compounds(IC50 = 91.7 μg/m L). Conclusion Apart from compounds 4 and 5, other eight compounds are reported in this plant for the first time. All compounds show no QSI activity, compound 10 shows potential cytotoxic activity on SGC7901 cells in vitro.Jing Qi Ruo-fu Shi Jian-ming Yu Yi Li Sheng-tao Yuan Ji-zhu Yang Jiang-miao Hu Ai-qun Jia 2016Chinese Herbal Medicines2016,8,1:23
18The TanSat mission: preliminary global observations显示文摘The Chinese global carbon dioxide monitoring satellite (Tan Sat) was launched successfully in December2016 and has completed its on-orbit tests and calibration. Tan Sat aims to measure the atmospheric column-averaged dry air mole fractions of carbon dioxide (XCO_2) with a precision of 4 ppm at the regional scale, and in addition, to derive global and regional CO2fluxes. Progress towards these objectives is reviewed and the first scientific results from Tan Sat measurements are presented. Tan Sat on-orbit tests indicate that the Atmospheric Carbon dioxide Grating Spectrometer is in normal working status and is beginning to produce L1B products. The preliminary Tan Sat XCO_2products have been retrieved by an algorithm and compared to NASA Orbiting Carbon Observatory-2 (OCO-2) measurements during an overlapping observation period. Furthermore, the XCO_2retrievals have been validated against eight groundsite measurement datasets from the Total Carbon Column Observing Network, for which the preliminary conclusion is that Tan Sat has met the precision design requirement, with an average bias of 2.11 ppm.The first scientific observations are presented, namely, the seasonal distributions of XCO_2over land on a global scale.Yi Liu Jing Wang Lu Yao Xi Chen Zhaonan Cai Dongxu Yang Zengshan Yin Songyan Gu Longfei Tian Naimeng Lu Daren Lyu 2018Science Bulletin2018,63,18:23
19A novel gene delivery system targeting cells expressing VEGF receptors显示文摘Two ligand oligopeptides GV1 and GV2 were designed according to the putative binding region of VEGF to its receptors. GV1, GV2 and endosome releasing oligopeptide HA20 were conjugated with poly-L-lysine or protamine and the resulting conjugates could interact with DNA in a noncovalent bond to form a complex. Using pSV2-β-galactosidase as a reporter gene, it has been demonstrated that exogenous gene was transferred into bovine aortic arch-derived endothelial cells (ABAE) andhuman malignant melanoma cell lines (A375) in vitro. In vivo experiments, exogenous gene was transferred into tumor vascular endothelial cells and tumor cells of subcutaneously transplanted human colon cancer LOVO, human malignant melanoma A375 and human hepatoma graft in nude mice. This system could also target gene to intrahepatically transplanted human hepatoma injected via portal vein in nude mice. These results are correlated with theGene delivery system targeting VEGF receptors relevant receptors (flt-1, flk-1/KDR) expression on the targeted cells and tissues.LI JUN MIN JUN SONG HAN YI HUANG PEI KUN TIAN SHU MIN QU MIN YAO HUI QIU JIANG DA FANG WAN JING CHU LUO CHENG XIAO GU JIAN REN GU( National Labomtory for Oncogenes and Related Genes, Shanghai Cancer Institute, Shanghai 200032,China)(National Laboratory of 1999Cell Research1999,9,1:22
20Intracoronary arterial retrograde thrombolysis with percutaneous coronary intervention: a novel use of thrombolytic to treat acute ST-segment elevation myocardial infarction显示文摘Background Clearance of coronary arterial thrombosis is necessary in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). There is currently no highly-recommended method of thrombus removal during interventional procedures. We describe a new method for opening culprit vessels to treat STEMI: intracoronary arterial retrograde thrombolysis (ICART) with PCI. Methods & Results Eight patients underwent ICART. The guidewire was advanced to the distal coronary artery through the occlusion lesion. Then, we inserted a microcatheter into the distal end of the occluded coronary artery over the guidewire. Urokinase (5–10 wu) mixed with contrast agents was slowly injected into the occluded section of the coronary artery through the microcatheter. The intracoronary thrombus gradually dissolved in 3–17 min, and the effect of thrombolysis was visible in real time. Stents were then implanted according to the characteristics of the recanalized culprit lesion to achieve full revascularization. One patient experienced premature ventricular contraction during vascular revascularization, and no malignant arrhythmias were seen in any patient. No reflow or slow flow was not observed post PCI. Thrombolysis in myocardial infarction flow grade and myocardial blush grade post-primary PCI was 3 in all eight patients. No patients experienced bleeding or stroke. Conclusions ICART was accurate and effective for treating intracoronary thrombi in patients with STEMI in this preliminary study. ICART was an effective, feasible, and simple approach to the management of STEMI, and no intraprocedural complications occurred in any of the patients. ICART may be a breakthrough in the treatment of acute STEMI.Jin-Wen TIAN Mei ZHU Feng-Qi WANG Ke LI Chao-Fei ZHOU Bo LI Min WANG Jue-Lin DENG Bo JIANG Jing BAI Yi GUO Rong-Jie JIN Zhao ZHANG Ying LIN Ji-Hang WANG Shi-Hao ZHAO Ming-Zhi SHEN 2019Journal of Geriatric Cardiology2019,16,6:22
