| 1 | Lentiviral-mediated gene transfer into human adipose-derived stem cells:role of NELL1 versus BMP2 in osteogenesis and adipogenesis in vitro显示文摘(NELL1 ) 象 NEL 一样分子 1 是与 craniosynostosis 联系的一个有势力 osteogenic 因素。侵入人体气管粘膜的病菌,大多数通常为基因治疗使用了病毒的向量,有可以限制成骨的几劣势。以前的研究证明了 lentiviruses 能为骨头新生为基因治疗用作理想的向量。在这研究,编码人的 NELL1 和骨头的二 lentiviral 向量(LvNELL1 和 LvBMP2 ) 分别地,形态基因的 protein-2 (BMP2 ) 被构造。在 vitro 的人的脂肪质导出干细胞(hADSCs ) 的增长,成骨,和 adipogenesis 上的 LvNELL1 感染的效果被估计并且与 LvBMP2 的相比。结果显示出感染 LvNELL1 的那 hADSCs 能高效地并且稳定地 overexpress 目标基因。3-(4,5-dimethylthiazol-2-yl )-2,5-diphenyltetrazolium 溴化物试金结果表明了那 LvBMP2,然而并非 LvNELL1,提高了 hADSCs 的增长。对碱的磷酸酶活动和细胞的矿化作用的评价显示 LvNELL1 感染支持了 hADSCs 的 osteogenic 区别,并且效果与 LvBMP2 的是可比较的。实时聚合酶链反应(PCR ) 在 hADSCs 揭示了那 LvNELL1 感染 upregulated OSX 表情然而并非 RUNX2 表示。另外,分析显示出的 adipogenic 标记(类脂化合物微滴, peroxisome 激活 proliferator 受体,和脂蛋白脂肪分解酵素) LvNELL1 能戏剧性地禁止 hADSCs,而是 LvBMP2 的 adipogenic 区别,这没有如此的效果。一起拿,这些调查结果建议在 hADSCs 的调停 lentiviral 的 NELL1 基因转移可以是一条新奇、有希望的途径完成有效、精确的骨头新生。 | Yajing Liu Caiyun Chen Huixia He Dongsheng Wang LingLing E Zhongyu Liu Hongchen Liu | 2012 | Acta Biochimica et Biophysica Sinica2012,44,10: | 10 |

| 3 | Development and validation of a questionnaire-based risk scoring system to identify individuals at high risk for gastric cancer in Chinese populations显示文摘Objective:This study aimed to develop and validate a risk scoring system to identify high-risk individuals carrying malignant lesions in stomach for tailored gastric cancer screening.Methods:A gastric cancer risk scoring system(GC-RSS)was developed based on questionnaire-based predictors for gastric cancer derived from systematic literature review.To assess the capability of this system for discrimination,risk scores for 8,214 and 7,235 outpatient subjects accepting endoscopic examination in two endoscopy centers,and 32,630 participants in a community-based cohort in China were calculated to plot receiver operating characteristic curves and generate area under the curve(AUC).To evaluate the performance of GC-RSS,the screening proportion,sensitivity and detection rate ratio compared to universal screening were used under different risk score cutoff values.Results:GC-RSS comprised nine predictors including advanced age,male gender,low body mass index(<18.5 kg/m^(2)),family history of gastric cancer,cigarette smoking,consumption of alcohol,preference for salty food,irregularity of meals and consumption of preserved food.This tool performed well in determining the risk of malignant gastric lesions with AUCs of 0.763,0.706 and 0.696 in three validation sets.When subjects with risk scores≥5 were evaluated with endoscopy,nearly 50%of these endoscopies could be saved with a detection rate of over 1.5 times achieved.When the cutoff was set at 8,only about 10%of subjects with the highest risk would be offered endoscopy,and detection rates for gastric cancer could be increased 2-4 fold compared to universal screening.Conclusions:An effective questionnaire-based GC-RSS was developed and validated.This tool may play an important role in establishing a tailored screening strategy for gastric cancer in China. | Ren Zhou Hongchen Zheng Mengfei Liu Zhen Liu Chuanhai Guo Hongrui Tian Fangfang Liu Ying Liu Yaqi Pan Huanyu Chen Zhe Hu Hong Cai Zhonghu He Yang Ke | 2021 | Chinese Journal of Cancer Research2021,33,6: | 3 |

| 8 | Pt supported on Zn modified silicalite-1 zeolite as a catalyst for n-hexane aromatization显示文摘Platinum(Pt)supported on Zinc(Zn)modified silicalite-1(S-1)zeolite(denoted as Pt-Zn/S-1)was prepared by using a wetness-impregnation method and applied in the n-hexane aromatization reaction for the first time.Both Lewis and Bronsted acid sites were detected in Pt-Zn/S-1 catalyst by means of FT-IR adsorption of NH3 experiment,which were identified as mostly weak and medium ones.Besides,Pt and Zn species showed strong interaction,as revealed by the TPR(Temperature-programmed reduction)and XPS(X-ray photoelectron spectroscopy)experiments.Pt-Zn/S-1 catalyst exhibited excellent aromatization function rather than isomerization and cracking side reactions in the conversion of n-hexane.Pulse experimental study showed that 75.6%of n-hexane conversion and 76.8%of benzene selectivity were obtained over Pt0.1-Zn60/S-l catalyst at 550℃ and under atmospheric pressure.By spectroscopy tests and pulse experimental results,it was concluded that the n-hexane aromatization over Pt-Zn/S-1 catalyst follows a metal-acid bifunctional mechanism.Furthermore,with the assistance of Zn,the electron-deficient Pt species in Pt-Zn/S-1 showed good sulfur tolerance performance. | Guodong Liu Jiaxu Liu Ning He Shishan Sheng Guiru Wang Hongchen Guo | 2019 | Journal of Energy Chemistry2019,28,7: | 1 |

| 10 | Surface defect and lattice engineering of Bi_(5)O_(7)Br ultrathin nanosheets for efficient photocatalysis显示文摘The effective separation and migration of photogenerated charge carriers in bulk and on the surface of photocatalysts will significantly promote photocatalytic efficiency.However,the synchronous regulation of photocharges on both counts is challenging.Herein,the simultaneous separation of bulk and surface photocharges is conducted to enhance photocatalytic activity by coupling the surface defects and lattice engineering of bismuth oxybromide.The depth-modulated Bi_(5)O_(7)Br ultrathin nanosheets with an abundance of bismuth in the crystal structure increased the internal electric field,which propelled the separation and migration of photocharges from bulk to the surface.Creation of oxygen vacancies(OVs)on the nanosheet surface forms local electric fields,which can stimulate the migration of charges to active sites on the catalyst surface.Therefore,the OV-assembled Bi_(5)O_(7)Br nanosheets demonstrated enhanced photocatalytic degradation efficiency under simulated solar-light illumination.This study proved the possibility of charge governing via electric field modulation based on an integrated strategy. | Yunjing Wang Hongchen He Yunjiang Wang Meili Xie Feng Jing Xianhong Yin Feilong Hu Yan Mi | 2023 | Nano Research2023,16,1: | 1 |
| 11 | Microwave Drying of Scots Pine Lumber:Structure Changes,Its Effect on Liquid Permeability显示文摘Microwave(MW)drying method was adopted to enhance the liquid permeability of Scots pine lumber.Structure changes were characterized by stereoscope microscope,scanned electron microscope(SEM)and transmission electron microscope(TEM)examination.Pore parameters before and after MW treatment were detected by mercury intrusion porosimetry(MIP)method,and the effect of structure changes on liquid permeability were analyzed.As stereoscope microscope,SEM and TEM examination results showed,macro and micro checks mainly developed at intercellcular of tracheids,intercellular of ray parenchyma and tracheid,while these checks extend main along the radial-longitudinal plane.Pit border destruction,aspirated pits’orus translocation and micro-checks in tracheid cell wall were also observed.MIP test shown that pore volume and pore area increased as macro and micro checks generated to form new cavities.Microstructure changes would increase the quantity of pores or enlarge the pore diameter.Liquid flow pathways increased as macro and micro checks generated,aspirated pits reopened to form new pathways;liquid flow efficiency improved as porosity,pore volume and pore diameter increased which facilitated the liquid flow. | Sheng He Weiqi Leng Yuhe Chen Hongchen Li Jingpeng Li Zaixing Wu Zizhang Xiao | 2023 | Journal of Renewable Materials2023,11,1: | 0 |
