| 5 | 普通杏和西伯利亚杏野生居群遗传多样性与其地理分布关系研究显示文摘地理距离可能有利于陆地植物种群的遗传分化,了解地理因素如何影响基因流和居群遗传结构,对于遗传多样性保护至关重要。本研究以桃李属(Prunus L.)2个自然分布的种,即欧亚大陆的西伯利亚杏(Prunus sibirica L.)和中亚地区的普通杏(Prunus armeniaca L.)共计16个野生居群为材料。本研究筛选多态性较好的18个微卫星DNA标记进行基因分型,应用贝叶斯模型分析其遗传多样性和居群遗传结构。本研究发现:(1)起源于中国华北和东北地区的西伯利亚杏野生居群的遗传变异和遗传多样性较中亚普通杏野生居群丰富,2个杏野生居群的遗传结构诠释了各自不同的最佳遗传群簇(K);(2)中国西伯利亚杏居群的遗传群簇分布具有地理差异特征,处于西北地区的居群呈现孤立结构,可能是与复杂的生态环境和地理上栖息自西向东的分布广泛有关;中亚地区野生普通杏居群的遗传结构呈高度杂合,可能由最近发生在有限地理分布区域中居群间的基因流引起;(3)地理隔离(IBD)解析了遗传分化与地理梯度之间的相关关系,表明中国西伯利亚杏野生居群的地理距离与遗传距离之间存在显著的相关性,而在中亚的普通杏野生居群中则不同。综上,本研究指出与生态地理模式相关的遗传结构可能会影响杏属植物的遗传分化和遗传多样性,但对遗传分化和多样性的影响程度在不同的杏种居群中有所不同。基于此,进一步讨论了开展遗传多样性保护的可能策略和意义。 | 刘硕 Decroocq Veronique 张玉军 刘宁 马小雪 章秋平 徐铭 张玉萍 刘威生 | 2020 | 植物遗传资源学报2020,21,6: | 6 |
| 6 | 基于GreenLab原理构建油松成年树的结构-功能模型显示文摘林木的结构-功能模型(functional-structural tree modeling,FSTMs)是基于器官级组件构建的将植物结构和功能结合起来的一类模型,在应用于成年树时需要解决拓扑结构复杂性和年轮分配模式普适性的问题。该文以18年生和41年生的油松(Pinus tabulaeformis)成年树为研究对象,将GreenLab模型应用到成年树的模拟中。采用破坏性取样,实测了2株油松成年树的形态结构,利用子结构模型解决成年树拓扑结构复杂性的问题,引入年轮影响系数λ,将全局分配模式和Pressler模式结合起来,解决年轮分配模式在不同年龄和环境条件下不同的问题。模型的直接参数通过实测数据获得,隐含参数利用非线性最小二乘法拟合反求获得。通过实测数据与模拟数据的对比、模拟数据与经验模型模拟数据的对比,对模型的模拟效果进行了评估,发现节间总重、针叶总重、树高、树干节间重观测值和模型模拟值建立的回归方程的决定系数为0.84-0.98,结构-功能模型与经验模型对总生物量模拟的决定系数为0.95,表明该模型能较真实地反映油松的结构和生长过程。 | 国红 雷相东 Veronique LETORT 陆元昌 | 2011 | 植物生态学报2011,35,4: | 6 |
| 7 | Acceptability of an acupuncture intervention for geriatric chronic pain: an open pilot study显示文摘OBJECTIVE: This study investigated the acceptability and effectiveness of acupuncture for persistent musculoskeletal pain in the elderly and assessed the conditions for a future controlled trial. METHODS: A total of 60 patients, hospitalized in a geriatric hospital were enrolled. The intervention consisted of eight acupuncture sessions. The main outcome was the patient's participation rate. Regarding pain, the evaluation was based on pre- and post-treatment variations. As a high proportion of the patients had cognitive impairment, the behavioral pain scale DOLOPLUS-2 was chosen although self evaluation was used wherever possible. RESULTS: The mean age of the patients was 83 years. The acceptance rate was very high (89.6%) and 90% of the patients completed the entire course of treatment. After five weeks, the mean DOLOPLUS score had decreased significantly (P<0.01). The patients reported improved sleep quality and a reduction in their anxiety symptoms. Furthermore, caregivers noticed a decrease in patient aggressiveness making care easier. CONCLUSION: Our results suggest that acupuncture is highly acceptable and could be very useful in the management of chronic pain when performed in very old frail people with chronic physical and mental disability. | Marie-France Couilliot Veronique Dareest Bruno.Tenenbaum Gerard Delahaye Philippe Ercolano Maud Carcaille Pavia Vytopilova Bruno Tenenbaum Eric Vicaut | 2013 | Journal of Integrative Medicine2013,11,1: | 5 |

| 11 | Pulmonary hypertension in hereditary haemorrhagic telangiectasia显示文摘Hereditary haemorrhagic telangiectasia(HHT) is an autosomal dominant inherited disorder characterised by vascular malformations in predominantly the brain,liverand lungs.Pulmonary hypertension(PH) is increasingly recognised as a severe complication of HHT.PH may be categorised into two distinct types in patients with HHT.Post-capillary PH most often results from a high pulmonary blood flow that accompanies the high cardiac output state associated with liver arteriovenous malformations.Less frequently,the HHT-related gene mutations in ENG or ACVRL1 appear to predispose patients with HHT to develop pre-capillary pulmonary arterial hypertension.Differentiation between both forms of PH by right heart catheterisation is essential,since both entities are associated with severe morbidity and mortality with different treatment options.Therefore all HHT patients should be referred to an HHT centre. | Veronique MM Vorselaars Sebastiaan Velthuis Repke J Snijder Jan Albert Vos Johannes J Mager Martijn C Post | 2015 | World Journal of Cardiology2015,7,5: | 4 |

| 15 | FOLFIRI plus bevacizumab as a second-line therapy for metastatic intrahepatic cholangiocarcinoma显示文摘AIM:To evaluate the efficacy and tolerance of FOLFIRI plus bevacizumab treatment outcome as second-line treatment for metastatic intrahepatic cholangiocarcinoma.METHODS:Thirteen consecutive patients with metastatic intrahepatic cholangiocarcinoma who were refractory tofirst-line therapy consisting of gemcitabine plus oxaliplatinbased first-line chemotherapy given intravenously via intra-arterial infusion were treated with FOLFIRI[irinotecan(180 mg/m2 i.v.over 90 min)concurrently with folinic acid(400 mg/m2 i.v.over 120 min)followed by fluorouracil(400 mg/m2 i.v.bolus)then fluorouracil 2400 mg/m2 intravenous infusion over 46 h]and bevacizumab(5mg/kg)every 2 wk.Tumor response was evaluated by computed tomography scan every 4 cycles.RESULTS:The best tumor responses using response evaluation criteria in solid tumor criteria were:complete response for 1 patient,partial response for 4 patients,and stable disease for 6 patients after 6 mo of follow-up.The response rate was 38.4%(95%CI:12.5-89)and the disease control rate was 84.5%(95%CI:42-100).Seven deaths occurred at the time of analysis,progression free survival was 8 mo(95%CI:7-16),and median overall survival was 20 mo(95%CI:8-48).No grade 4toxic events were observed.Four grade 3 hematological toxicities and one grade 3 digestive toxicity occurred.An adaptive reduction in chemotherapy dosage was required in 2 patients due to hematological toxicity,and a delay in chemotherapy cycles was required for 3 patients.CONCLUSION:FOLFIRI plus bevacizumab combination treatment showed promising efficacy and safety as second-line treatment for metastatic intrahepatic cholangiocarcinoma after failure of the first-line treatment of gemcitabine plus oxaliplatin chemotherapy. | Jean-Florian Guion-Dusserre Veronique Lorgis Julie Vincent Leila Bengrine Francois Ghiringhelli | 2015 | World Journal of Gastroenterology2015,21,7: | 2 |
| 16 | Prognostic value of chemotherapy-induced hematological toxicity in metastatic colorectal cancer patients显示文摘AIM: To establish whether chemotherapy-induced neutropenia is predictive of better outcome in patients with metastatic colorectal cancer(mCRC). METHODS: Survival and patient characteristics from consecutive mCRC patients treated in the Centre Georges Francois Leclerc, Dijon, France between January 2001 and December 2011 were analyzed. Patient and tumor characteristics, hematological toxicity(neutropenia, anemia, and thrombocytopenia), and type of chemotherapy received were recorded. RESULTS: We retrospectively analyzed data from 399 consecutive patients with mCRC who received at least one line of chemotherapy. Median follow up was 6.3 years. Eighty-eight percent of the patients received more than two lines of chemotherapy. By univariate analysis, whatever their grade, neutropenia and thrombocytopenia occurring during the first two lines of chemotherapy were significantly associated with better overall survival(HR = 0.55, 95%CI: 0.43-0.70, P < 0.0001 and HR = 0.70, 95%CI: 0.56-0.88, P = 0.025 respectively). In contrast, anemia during chemotherapy was significantly associated with poorer overall survival(HR = 1.9, 95%CI: 1.22-2.97, P = 0.005). Multivariate analysis revealed that both neutropenia and thrombocytopenia were significantly associated with better overall survival: HR = 0.43, 95%CI: 0.29-0.64, P < 0.0001 and HR = 0.69, 95%CI: 0.49-0.98, P = 0.036, respectively. CONCLUSION: These data suggest that occurrence of neutropenia or thrombocytopenia during first- or second-line chemotherapy for mCRC is associated with better survival. | Laurie Rambach Aurelie Bertaut Julie Vincent Veronique Lorgis Sylvain Ladoire Francois Ghiringhelli | 2014 | World Journal of Gastroenterology2014,20,6: | 2 |
| 17 | Chemical constituents, cytotoxic, antifungal and antimicrobial properties of Centaurea diluta Ait. subsp. algeriensis(Coss. & Dur.) Maire显示文摘Objective:To investigate the chemical composition of a moderately polar extract(CHC1_3 soluble part of the MeOH-H_2O extract) obtained from the aerial parts(leaves and flowers) of Centaurea diluta Ait.subsp.algeriensis(Coss.& Dur.) Maire,a species endemic to Algeria and Morocco on which no reports are available to date.To evaluate in vitro the cytotoxic,antifungal and antimicrobial activities of this extract and the cytotoxic and antimicrobial activities of its isolated secondary metabolites.Methods:The cytotoxic effects of the extract were investigated on 3 human cancer cell lines i.e.the A549 non-small-cell lung carcinoma(NSCLC),the MCF7 breast adenocarcinoma and the U373 glioblastoma using a MTT colorimetric assay.Biological data allowed to guide the fractionation of the extract by separation and purification on silica gel 60(CC and TLC).The isolated compounds which were characterized by spectral analysis,mainly HR-ESIMS,HR-EIMS,UV and NMR experiments(~1H,^(13)C,COSY,ROESY,HSQC and HMBC) and comparison of their spectroscopic data with those reported in the literature,were evaluated for cytotoxic activities on six cancer cell lines(A549,MCF7,U373,Hs683 human glioma,PC3 human prostate and B16-F10 murine melanoma).The direct and indirect antibacterial and antifungal activities were determined using microdilution methods for the raw extract and TLC-bioautography and microdilution methods against standard and clinical strains for the isolated compounds.Results:The raw extract reduced cell viability with IC_(50)s of 27,25 and 21 μg/mL on A549,MCF7 and U373,respectively.Five secondary metabolites:two phenolic compounds(vanillin 1,paridol 3),a lignan[(-)-arctigenin 2]and two flavonoid aglycones(eupatilin 4 and jaceosidin 5),were then isolated from this extract.Moderate cytotoxic effects were observed for(-)-arctigenin 2(IC_(50)s:28 and 33μM on Hs683 and B16-F10,respectively),eupatilin 4(IC_(50)s:33 and 47 μM on B16-F10 and PC3,respectively) and jaceosidin 5(IC_(50)s:32 and 40 μM on PC3 and B16-F10,respectively).Conclusions:All the isolated compounds were described for the first time from this species.Although inactive against 7 tested microorganisms(fungi,bacteria and yeast,human or plant pathogens),the raw extract was able to potentiate the effect of beta-lactam antibiotics on methicillin-resistant Staphylococcus aureus(MRSA),reducing the minimal inhibitory concentrations(MICs) by a factor of 2-32-fold.No synergy was found between the extract and streptomycin.From the five isolated compounds only jaseosidin 5 showed a moderate antimicrobial activity. | Hanene Zater Joelle Huet Veronique Fontaine Samir Benayache Caroline Stevigny Pierre Duez Fadila Benayache | 2016 | Asian Pacific Journal of Tropical Medicine2016,9,6: | 2 |
| 18 | 外加电源式再碱化处理的耐久性探究显示文摘为了探究利用外加电源方式对钢筋混凝土进行再碱化处理的耐久性效果,人工碳化钢混板经过8.5 d的再碱化处理后,在恒温恒湿实验室里存放540 d,然后在室外自然老化360 d.期间,采用多种分析化学方法(酚酞指示剂法;混凝土粉样测试法;原子吸收光谱法)对混凝土的再碱化程度进行量化分析,同时应用多种电化学技术(自由电势、线性极化电阻技术、电化学阻抗技术)对钢筋腐蚀的活性变化进行评估.实验结果表明:采用外加电源方式对碳化钢筋混凝土进行再碱化处理后,混凝土保护层可在一定程度上被有效的再碱化,且具有很好的耐久性,但钢筋腐蚀的活性只在短期内(360 d左右)有效下降,900 d后,其活性又恢复到处理前的水平. | 童芸芸 BOUTEILLER Veronique MARIE-VICTOIRE Elisabeth JOIRET Suzanne | 2011 | 浙江大学学报(工学版)2011,45,9: | 2 |
| 19 | Hydrogenation of cinnamaldehyde over bimetallic Au-Cu/CeO_2 catalyst under a mild condition显示文摘Bimetallic Au_xCu_y/CeO_2(x/y = 3/1,1/1,and 1 /3) catalysts were prepared by direct anion exchange(DAE),following impregnation(IMP) methods,and used for selective hydrogenation of cinnamaldehyde.The effects of pretreatments,such as calcination or reduction on the catalytic activities of these catalysts were investigated.XRD and HRTEM showed that for the reduced catalysts,there is the formation of an Au-Cu alloy.HAADF-STEM displayed that reduction pretreatment leads to a very homogenous distribution of Au and Cu on the external catalyst surface.Reaction parameters,such as CAL concentration,the stirring speed,nature of the solvent influence the catalytic activities.Pretreatments lead to a major effect on CAL conversion and HCAL selectivity.Catalysts Au_xCu_y/CeO_2 pretreated under reduction display higher CAL conversion and HCAL selectivity than that of under calcination mainly due to the synergistic effect resulting in a formation of Au-Cu alloy. | Xue-Mei Liao Veronique Pitchon Pham-Huu Cuong Wei Chu Valerie Caps | 2017 | Chinese Chemical Letters2017,28,2: | 2 |
