| 1 | Mesoporous iron oxide-silica supported gold catalysts for low-temperature CO oxidation显示文摘Mesoporous iron oxide-silica composite with a high silica content was synthesized by hydrothermal method,and another composite material with a high iron content was obtained by etching part of silica in alkaline solution.Gold catalysts were loaded onto both composites by a deposition-precipitation method,and used for CO oxidation.The samples were characterized by BrumauerEmmet-Teller(BET),X-ray diffraction(XRD),X-ray photoelectron spectra(XPS),transmission electron microscope(TEM)and scanning electron microscope(SEM)techniques.Both composites had high specific surface areas and were amorphous.The Au nanoparticles dispersed on the surface of the composites existed in metallic state.Composite with high silica content was not suitable for Au loading,and its supported gold catalyst showed poor performance in catalytic reaction.In contrast,composite with high iron content allowed efficient Au loading,and CO could be oxidized completely at low temperature on its supported gold catalyst.The effects of deposition-precipitation pH values on Au loading and activity of the catalyst were investigated,and the results indicated that Au loading was the highest and the catalyst was the most active for CO oxidation when the synthesis pH was adjusted to 8. | Weidong Zhang Xiaofei Lu Weili Zhou Feng Wu Jinjun Li | 2014 | Chinese Science Bulletin2014，59，31： | 3 |
| 2 | Effect of aqueous extract of Sanweitanxiang powder on calcium homeostasis protein expression in ischemic-reperfusion injury rat heart显示文摘OBJECTIVE: To investigate the underlying mechanism of reduced myocardial ischemia-reperfusion (I/R) injury in rats using the traditionalTibetan medicine Sanweitanxiang powder (SWTX). METHODS: Rats were randomly divided into six groups (n=10) as follows: (a) propranolol dinitrate control group, given propranolol dinitrate 0.02 g/kg for 10 days before I/R, (b) SWTX with a high dose group, given SWTX 1.5 g/kg for 10 days before I/R, (c) SWTX with a medium dose group, given SWTX 1.25 g/kg for 10 days before I/R, (d) sham group (Sham), in which the rat heart was exposed by pericardiotomy but without I/R, (e) SWTX with a low dose group, given SWTX 1.0 g/kg for 10 days before I/R, and (f) I/R injury group. Rats were intragastrically pretreated with propranolol dinitrate orSWTX. After that, the operation to cause ischemia and reperfusion was conducted.The histopathologic changes of rat hearts were observed by hematoxylin and eosin staining and transmission electron microscopy. Ca2+ homeostasis protein expression was determined by western blot. RESULTS: After SWTX pretreatment, the development of ultrastructural pathological changes from IR injury was attenuated. A decrease in the expression of B-cell lymphoma 2 associated X protein, and an increase in the expression of B-cell lymphoma 2 were observed. An increased activation of extracellular signal regulated kinases were found. Compared with the sham group, the expression of sarcoplasmic reticulum calcium-ATPase, phospholamban, and calsequestrin were all up-regulated after pretreatment with SWTX. CONCLUSION: The protective mechanism of SWTX pretreatment on myocardial I/R injury might be related to its effect on maintaining the balance of calcium homeostasis in rat heart. | Mei Yang Shuna Zhang Shicun Ren Jinjun Wang Haixia Yun Sheng Yong Dejun Zhang Quanyu Yang Yiying Kou Dianxiang Lu Rili Ge | 2013 | Journal of Traditional Chinese Medicine2013，33，3： | 2 |
| 3 | Effect of Steam Explosion Technology Main Parameters on Moso Bamboo and Poplar Fiber显示文摘One of the large-scale industrial applications of Moso bamboo and poplar in China is the production of standardized fiberboard.When making fiberboard,a steam blasting pretreatment without the addition of traditional adhesives has become increasingly popular because of its environmental friendliness and wide applicability.In this study,the steam explosion pretreatment of Moso bamboo and poplar was conducted.The steam explosion pressure and holding time were varied to determine the influence of these factors on fiber quality by investigating the morphology of the fiber,the mass ratio of the unexploded specimen at the end face,the chemical composition,and the tensile strength.The following conclusions were drawn:As the steam burst pressure and holding time increased,more cellulose and hemicellulose degradation occurred(the degradation of hemicellulose was greater than that of cellulose),the lignin content rose,and the fiber bundle strength decreased.The degradation of bamboo cellulose was slightly higher than that of poplar,and the degradation of poplar hemicellulose was significantly faster than that of bamboo.Furthermore,increasing the steam explosion pressure and pressure holding time could not effectively increase the lignin content.It is recommended to use a steam blasting pressure of 2.5 MPa or 3.0 MPa and a holding time of 180 s to perform steam blasting on bamboo and poplar specimens. | Biqing Shu Qin Ren Lu Hong Zhongping Xiao Xiaoning Lu Wenya Wang Junbao Yu Naiqiang Fu Yiming Gu Jinjun Zheng | 2021 | Journal of Renewable Materials2021，9，3： | 1 |
| 4 | New Algorithm Rules Out Acute-on-chronic Liver Failure Development within 28 Days from Acute Decompensation of Cirrhosis显示文摘Background and Aims:Approximately 10%of patients with acute decompensated(AD)cirrhosis develop acute-on-chronic liver failure(ACLF)within 28 days.Such cases have high mortality and are difficult to predict.Therefore,we aimed to establish and validate an algorithm to identify these patients on hospitalization.Methods:Hospitalized patients with AD who developed ACLF within 28 days were considered pre-ACLF.Organ dysfunction was defined accord-ing to the chronic liver failure-sequential organ failure as-sessment(CLIF-SOFA)criteria,and proven bacterial infec-tion was taken to indicate immune system dysfunction.A retrospective multicenter cohort and prospective one were used to derive and to validate the potential algorithm,re-spectively.A miss rate of<5%was acceptable for the calcu-lating algorithm to rule out pre-ACLF.Results:In the deri-vation cohort(n=673),46 patients developed ACLF within 28 days.Serum total bilirubin,creatinine,international normalized ratio,and present proven bacterial infection at admission were associated with the development of ACLF.AD patients with≥2 organ dysfunctions had a higher risk for pre-ACLF patients[odds ratio=16.58195%confidence interval:(4.271-64.363),p<0.001].In the derivation co-hort,67.5%of patients(454/673)had≤1 organ dysfunction and two patients(0.4%)were pre-ACLF,with a miss rate of 4.3%(missed/total,2/46).In the validation cohort,65.9%of patients(914/1388)had≤1 organ dysfunction,and four(0.3%)of them were pre-ACLF,with a miss rate of 3.4%(missed/total,4/117).Conclusions:AD patients with≤1 organ dysfunction had a significantly lower risk of developing ACLF within 28 days of admission and could be safely ruled out with a pre-ACLF miss rate of<5%. | Xiaoting Tang Hai Li Guohong Deng Xin Zheng Xianbo Wang Yan Huang Yanhang Gao Zhongji Meng Zhiping Qian Feng Liu Xiaobo Lu Yu Shi Beiling Li Wenyi Gu Xiaomei Xiang Yan Xiong Yixin Hou Jun Chen Na Gao Sen Luo Liujuan Ji Jing Li Rongjiong Zheng Haotang Ren Jinjun Chen | 2023 | Journal of Clinical and Translational Hepatology2023，11，3： | 1 |
