Enhancing combinatorial properties,such as excellent corrosion resistance,high strength and good ductility combined,is an important issue for manufacturing high-quality AlMgSi(Cu)***,we show that this can be achieved by optimizing a combinatorial process consisting of pre-ageing,cold-rolling and post-ageing to tailor the hierarchical microstructures of the *** electron microscopy analysis reveals that the enhanced combinatorial properties of corrosion resistance,strength and ductility are owing to modification of grain boundary microstructure in good association with changes of precipitate microstructures and a more homogenous distribution of solute atoms,as compared with the microstructures of the alloy processed by thermal ageing only.

Cloning and functional analysis of a novel ascorbate peroxidase(APX) gene from Anthurium andraeanum

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2013年第12期14卷 1110-1120页

作者： hui-chun liu Dan-qing TIAN Jian-xin liu Guang-ying MA Qing-cheng ZOU Zhu-jun ZHU College of Agriculture & Biotechnology Zhejiang University Research & Development Center of Flower Zhejiang Academy of Agricultural Sciences School of Agricultural and Food Science Zhejiang A&F University

An 888-bp ful-length ascorbate peroxidase （APX） complementary DNA （cDNA） gene was cloned from Anthurium andraeanum, and designated as AnAPX. It contains a 110-bp 5′-noncoding region, a 28-bp 3′-noncoding region, and a 750-bp open reading frame （ORF）. This protein is hydrophilic with an aliphatic index of 81.64 and its structure consisting ofα-helixes,β-turns, and random coils. The AnAPX protein showed 93%, 87%, 87%, 87%, and 86% similarities to the APX homologs from Zantedeschia aethiopica, Vitis pseudoreticulata, Gossypium hirsutum, Elaeis guineensis, and Zea mays, respectively. AnAPX gene transcript was measured non-significantly in roots, stems, leaves, spathes, and spadices by real-time polymerase chain reaction （RT-PCR） analysis. Interestingly, this gene expression was remarkably up-regulated in response to a cold stress under 6 °C, implying that AnAPX might play an important role in A. andraeanum tolerance to cold stress. To confirm this function we overexpressed AnAPX in tobacco plants by transformation with an AnAPX expression construct driven by CaMV 35S promoter. The transformed tobacco seedlings under 4 °C showed less electrolyte leakage （EL） and malondialdehyde （MDA） content than the control. The content of MDA was correlated with chilling tolerance in these transgenic plants. These results show that AnAPX can prevent the chilling challenged plant from cellmembrane damage and ultimately enhance the plant cold tolerance.

Anemia and risk of periprocedural cerebral injury detected by diffusion-weighted magnetic resonance imaging in patients undergoing transcatheter aortic valve replacement

引用

World Journal of Emergency Medicine 2022年第1期13卷 32-39页

作者： Stella Ng Qi-feng Zhu Ju-bo Jiang chun-hui liu Jia-qi Fan Ye-ming Xu Xian-bao liu Jian-an Wang Department of Cardiology the Second Affi liated Hospital of Zhejiang University School of MedicineHangzhou 310009China Zhejiang University School of Medicine Hangzhou 310058China

BACKGROUND: Anemia is prevalent in patients undergoing transcatheter aortic valve replacement(TAVR) and has been linked to impaired outcomes after the procedure. Few studies have evaluated the impact of anemia and new ischemic lesions post ***: We prospectively enrolled 158 patients who received TAVR in our center. Anemia was defined according to the World Health Organization criteria as hemoglobin <12 g/dL in women and <13 g/dL in men. All patients underwent diffusion-weighted magnetic resonance imaging(DW-MRI) procedure before and within 4–7 days after TAVR. RESULTS: Anemia was present in 85(53.8%) patients who underwent TAVR, and 126(79.7%) patients had 718 new DW-MRI positive lesions with a mean of 4.54±5.26 lesions per patient. The incidence of new ischemic lesions was 81.2% in patients with anemia versus 78.1% in patients without anemia(P=0.629). Moreover, anemic patients had bigger total volume/lesions in the anterior cerebral artery/middle cerebral artery(ACA/MCA) and MCA regions compared to the non-anemic patients(31.89±55.78 mm^(3) vs. 17.08±37.39 mm^(3), P=0.049;and 54.54±74.72 mm^(3) vs. 33.75±46.03 mm^(3), P=0.034). Anemia was independently associated with the volume/lesion in the ACA/MCA(β=16.796, 95% confidence interval [95% CI] 2.001 to 31.591, P=0.026) and in the MCA zone(β=0.020, 95% CI 0.001 to 0.040, P=0.041). CONCLUSIONS: Patients with pre-procedural anemia may have bigger total volume/lesions in the ACA/MCA and MCA regions compared to the non-anemic patients. Whether the consequences of bigger total volume/lesions impact neurological and cognitive outcomes remains to be investigated.

引用

Chinese Journal of Cancer Research 2014年第4期26卷 471-477页

作者： hui-chun liu Er-Bo Shan Lei Zhou Hao Jin Pei-Yuan Cui Yi Tan Yi-Min Lu Department of Hepatobiliary Surgery The First Affiliated Hospital of Bengbu Medical College

Objective： To observe the clinical effect of radiofrequency ablation （RFA） combined with transcatheter arterial chemoembolization （TACE） for advanced hepatocellnlar carcinoma （HCC）. Methods： A total of 92 eases of advanced primary liver cancer underwent TACE and RFA treatment from June 2005 to 2011 at the Department of Hepatobiliary Surgery, the First Affiliated Hospital of Bengbu Medical College. A total of 88 cases with complete clinical treatment and follow-up data were divided into two groups： 43 patients treated with TACE （TACE group） and 45 patients that received TACE combined with RFA treatment （TACE ＋ RFA group）. After clinical data assessment, tumor size and survival status were not significantly different between the groups as determined by stratified analysis. Results： Before and after surgery, spiral CT radiography and color comparison observed ablation conditions. The tumor necrosis rates after treatment （CR ＋ PR） were 67.4% （29/43） and 91.1% （41/45） for the TACE and combined treatment groups, respectively, and the difference was statistically significant （P〈0.05）. The quality of life was significantly improved for patients undergoing TACE ~ RFA compared with the control group. Survival duration was not significantly different in patients undergoing TACE ~ RFA compared with the control group. Conclusions： In this study, the effect of RFA combined with TACE treatment was better than TACE alone in treating advanced HCC.
