| 3 | Impact of cap-assisted colonoscopy during transendoscopic enteral tubing:A randomized controlled trial显示文摘BACKGROUND Colonic transendoscopic enteral tubing(TET)requires double cecal intubation,raising a common concern of how to save cecal intubation time and make the tube stable.We hypothesized that cap-assisted colonoscopy(CC)might reduce the second cecal intubation time and bring potential benefits during the TET procedure.AIM To investigate if CC can decrease the second cecal intubation time compared with regular colonoscopy(RC).METHODS This prospective multicenter,randomized controlled trial was performed at four centers.Subjects≥7 years needing colonic TET were recruited from August 2018 to January 2020.All subjects were randomly assigned to two groups.The primary outcome was the second cecal intubation time.Secondary outcomes included success rate,insertion pain score,single clip fixation time,purpose and retention time of TET tube,length of TET tube inserted into the colon,and all procedurerelated(serious)adverse events.RESULTS A total of 331 subjects were randomized to the RC(n=165)or CC(n=166)group.The median time of the second cecal intubation was significantly shorter for CC than RC(2.2 min vs 2.8 min,P<0.001).In patients with constipation,the median time of second cecal intubation in the CC group(n=50)was shorter than that in the RC group(n=43)(2.6 min vs 3.8 min,P=0.004).However,no difference was observed in the CC(n=42)and RC(n=46)groups of ulcerative colitis patients(2.0 min vs 2.5 min,P=0.152).The insertion pain score during the procedure in CC(n=14)was lower than that in RC(n=19)in unsedated colonoscopy(3.8±1.7 vs 5.4±1.9;P=0.015).Multivariate analysis revealed that only CC(odds ratio[OR]:2.250,95%confidence interval[CI]:1.161-4.360;P=0.016)was an independent factor affecting the second cecal intubation time in difficult colonoscopy.CC did not affect the colonic TET tube’s retention time and length of the tube inserted into the colon.Moreover,multivariate analysis found that only endoscopic clip number(OR:2.201,95%CI:1.541-3.143;P<0.001)was an independent factor affecting the retention time.Multiple regression analysis showed that height(OR:1.144,95%CI:1.027-1.275;P=0.014)was the only independent factor influencing the length of TET tube inserted into the colon in adults.CONCLUSION CC for colonic TET procedure is a safe and less painful technique,which can reduce cecal intubation time. | Quan Wen Kang-Jian Liu Bo-Ta Cui Pan Li Xia Wu Min Zhong Lu Wei Hua Tu Yu Yuan Da Lin Wen-Hung Hsu Deng-Chyang Wu Hong Yin Fa-Ming Zhang | 2020 | World Journal of Gastroenterology2020，26，39： | 1 |
| 4 | Description of adsorption of hydrophobic organic compounds on sediment using multi-component adsorption model显示文摘A chemical sequential separation procedure for sediment has been developed for the adsorptive investigation of hydrophobic organic compounds(HOCs) including four fractions: carbonate, hydrous metallic oxide(ferric oxide, manganese oxide and alumina), clay and organic matter. Adsorption isotherms of these hydrophobic solute probes, such as hexachloroethane, lindane and 1,2,4,5 tetrachlorobenzene were measured for model sorbents, model and natural sediment, and the latter of which was pretreated with the simplified sequential separation method. The linear and Langmuir models are applied to correlate the experimental data of humic substance and other model sorbents respectively. Multi component Adsorptive Model (MCAM) was used to simulate adsorption isotherms of model and natural sediment. The results reveal that(1) the separation efficiencies of carbonate, organic matter, ferric oxide, manganese oxide and alumina are 98.1%, 72.5%, 82.6%, 93.5% and 83.3%, respectively; (2) except for removing metallic oxide, the external structure of sediment is not changed greatly after separation; (3) the MCAM correlates the data of adsorption isotherm rather well with the maximal relative deviations of 9.76%, 6.78% and 9.53% for hexachloroethane, lindane and 1,2,4,5 tetrachlorobenaze in model sediment, respectively. The MCAM can clearly give expression to the different adsorptive mechanisms for HOCs in organic and inorganic matter, though the experimental data in each component are not very accurate due to the sequential separation efficiency. | QUAN Xie *, LIU Zhen yu, XUE Da ming, ZHAO Ya zhi, YANG Feng lin (School of Environmental Science and Technology, Dalian University of Technology, Dalian 116012, China. | 2002 | Journal of Environmental Sciences2002，14，2： | 1 |

| 7 | Moving Epidemic Method for Surveillance and Early Warning of Hand, Foot, and Mouth Disease in Beijing, China显示文摘Hand,foot,and mouth disease (HFMD) is an acute infection caused by enteroviruses that is commonly seen in children^([1]).High infectivity,large number of asymptomatic infections,complex transmission routes,and rapid spread make it difficult to control HFMD.Since 2008,China has reported> 23 million HFMD cases,including>0.15million severe cases^([2]).HFMD tops the list of notifiable infectious diseases in terms of case number and incidence rate,leading to a huge disease burden^([3]).Timely and accurate assessment of HFMD epidemics is essential for a holistic understanding of the outbreaks and for effective prevention and control strategies.Currently,there are no quantitative indicators to determine the duration and intensity of HFMD epidemics in Beijing. | DONG Shuai Bing WANG Yu HUO Da ZHAO Hao LIU Bai Wei LI Ren Qing GAO Zhi Yong WANG Xiao Li ZHANG Dai Tao WANG Quan Yi JIA Lei YANG Peng | 2023 | Biomedical and Environmental Sciences2023，36，12： | 0 |
| 8 | Neural stem cell transplantation alleviates functional cognitive deficits in a mouse model of tauopathy显示文摘The mechanisms of the transplantation of neural stem cells(NSCs)in the treatment of Alzheimer’s disease remain poorly understood.In this study,NSCs were transplanted into the hippocampal CA1 region of the rTg(tau P301L)4510 mouse model,a tauopathy model that is thought to reflect the tau pathology associated with Alzheimer’s disease.The results revealed that NSC transplantation reduced the abnormal aggregation of tau,resulting in significant improvements in the short-term memory of the tauopathy model mice.Compared with wild-type and phosphate-buffered saline(PBS)-treated mice,mice that received NSC transplantations were characterized by changes in the expression of multiple proteins in brain tissue,particularly those related to the regulation of tau aggregation or misfolding.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis and Gene Ontology(GO)function analysis revealed that these proteins were primarily enriched in pathways associated with long-term potentiation,neurogenesis,and other neurobiological processes.Changes in the expression levels of key proteins were verified by western blot assays.These data provided clues to improve the understanding of the functional capacity associated with NSC transplantation in Alzheimer’s disease treatment.This study was approved by the Beijing Animal Ethics Association and Ethics Committee of Beijing Institute of Technology(approval No.SYXK-BIT-school of life science-2017-M03)in 2017. | He-Ao Zhang Chun-Xu Yuan Ke-Fu Liu Qi-Fan Yang Juan Zhao Hui Li Qing-Hu Yang Da Song Zhen-Zhen Quan Hong Qing | 2022 | Neural Regeneration Research2022，17，1： | 0 |
| 9 | Building a greener future—Progress of the green building technology in the “13th Five-Year Plan” of China显示文摘The building sector plays an important role in energyconservation and carbon neutrality in China.Accordingto the Building Energy Research Center of TsinghuaUniversity,carbon dioxide(CO_(2))emissions account for38%of the total emissions,of which 16%and 22%arecontributed by building construction and operation,respectively(Hu et al.2022),Hence,promoting greenbuildings is proposed as an effective solution to the keyproblems of building industry development,including lowlabor productivity,high consumption of building materials,and high COz emissions in construction and operation.Greenbuildings are environmentlly responsible and resource-efficient throughout their life cycle from siting,design,andconstruction to operation,maintenance,renovation,anddeconstruction.They aim to use energy,water,and otherresources ficiently,while protecting occupant health andimproving productivity,adopting eco-friendly materials,and reducing the production of waste and pollution. | Min Song Xue Liu Shan Hu Quan Wen Da Yan | 2022 | Building Simulation2022，15，10： | 0 |
