| 1 | Photochemical pollution in Lanzhou, China - A case study显示文摘The photochemical air pollution in Xigu district of Lanshou city, Gansu Province was studied during a period of 1981-1984. The extremely high NMHC/NOx ratio and ozone level elevation after rain have been noticed. A series of outdoor and indoor reaction chamber simulation experiments conducted in order to understand the specific conditions. The ozone formation under NMHC/NOx condition and the possible reason for high ozone concentration after rain are discussed. | Tang Xiaoyan , Li Jinglong, Dong ZhenXing, Wang Yuying,Wang Wenxing , Qi Liwen, Liu Xiling, Zhang Yutian, Zhang Xuejin,Tian Bingshen, Jin Suwen , Yang Lingqing and Zhang Yixin Department of Technical Physics,Peking University, Beijing, China.

| 2 | Complement C7 is a novel risk gene for Alzheimer's disease in Han Chinese显示文摘Alzheimer's disease is the most common neurodegenerative disease,and has a high level of genetic heritability and population heterogeneity.In this study,we performed the whole-exome sequencing of Han Chinese patients with familial and/or early-onset Alzheimer's disease,followed by independent validation,imaging analysis and function characterization.We identified an exome-wide significant rare missense variant rs3792646(p.K420Q)in the C7 gene in the discovery stage(P=1.09×10^(-6),odds ratio=7.853)and confirmed the association in different cohorts and a combined sample(1615 cases and 2832 controls,P_(combined)=2.99×10^(-7),odds ratio=1.930).The risk allele was associated with decreased hippocampal volume and poorer working memory performance in early adulthood,thus resulting in an earlier age of disease onset.Overexpression of the mutant p.K420Q disturbed cell viability,immune activation and β-amyloid processing.Electrophysiological analyses showed that the mutant p.K420Q impairs the inhibitory effect of wild type C7 on the excitatory synaptic transmission in pyramidal neurons.These findings suggested that C7 is a novel risk gene for Alzheimer’s disease in Han Chinese. | Deng-Feng Zhang Yu Fan Min Xu Guihong Wang Dong Wang Jin Li Li-Li Kong Hejiang Zhou Rongcan Luo Rui Bi Yong Wu Guo-Dong Li Ming Li Xiong-Jian Luo Hong-Yan Jiang Liwen Tan Chunjiu Zhong Yiru Fang Chen Zhang Nengyin Sheng Tianzi Jiang Yong-Gang Yao | 2019 | National Science Review2019，6，2： | 6 |
| 3 | Traditional Chinese Medicine guidelines for coronavirus disease 2019显示文摘OBJECTIVE:To summarize the evidence from Traditional Chinese Medicine(TCM)practice in the treatment of coronavirus disease 2019(COVID-19)and provide timely clinical practice guidance.METHODS:The guidelines were developed in accordance with the World Health Organization rapid guideline process.The evidence on TCM for COVID-19 from published guidelines,direct and indirect published clinical evidence,first hand clinical data,and expert experience and consensus were collected.The grading of recommendations assessment,development and evaluation(GRADE)method was used to grade the evidence and make the recommendations.RESULTS:Based on the available evidence,the guidelines recommended 17 Chinese medicines for COVID-19:2 Chinese herbal granules,7 Chinese patent medicines,and 8 Chinese herbal injections.CONCLUSION:As the literature search was conducted on March,any subsequent versions of these guidelines require an up-to-date literature review.We hope that the evidence summary in these guidelines will be helpful in global efforts to address COVID-19. | Liang Ning Ma Yanfang Wang Jingya Li Huizhen Wang Xiaohui Jiao Liwen Liu Bin Ma Yan Zhao Chen Luo Xufei Zhao Siya Lu Meng Cao Jin Hu Wenpin Zhang Hairong Liu Guoxiu Lu Cheng Liu Mengyu Li Li Han Xuejie Liu Yuqi Wang Liying Zhao Xueyao Wei Dongfeng Bai Jing Sun Mingyu Yang Yong Wu Xiaodan Chen Yaolong Shi Nannan Wang Yanping Wang Yongyan | 2020 | Journal of Traditional Chinese Medicine2020，40，6： | 2 |

| 6 | Helical Poly(α,β-unsaturated ketone)with Bulky Pendant of Binaphthyl from Anionic Polymerization of(−)-Menthyl(S)-6'-Acrylyl-2'-methyloxy-1,1'-binaphthalene-2-carboxylate显示文摘(−)-Menthyl(S)-6'-acrylyl-2'-methyloxy-1,1'-binaphthalene-2-carboxylate(3)was synthesized and anionically polymerized using n-BuLi as an initiator in toluene.The monomer 3 was levorotatory and had an[α]_(D)^(25)value of−72.4,but its corresponding polymer poly-3 was dextrorotatory and showed an[α]_(D)^(25)value of+162.0.Poly-3 was confirmed to exist in the form of one-handed helical structure in solution by means of comparing the specific optical rotation and the CD spectra with that of 3 and the model compounds such as(−)-menthyl(S)-6'-propionyl-2'-methyloxy-1,1'-binaphthalene-2-carboxylate 2b and(−)-menthyl(S)-6'-heptanoyl-2'-methyloxy-1,1'-binaphthalene-2-carboxylate 2c.This conclusion was also confirmed by the fact that the g-value of poly-3 is about 11 times of that of monomer 3. | Yehui Chen Liwen Yang Nianfa Yang Zhusheng Yang Jin Zhang | 2014 | Chinese Journal of Chemistry2014，32，3： | 1 |

| 9 | Thermo-fluidic characteristics of natural convection in honeycombs:The role of chimney enhancement显示文摘The natural convective heat transfer performance and thermo-fluidic characteristics of honeycombs with/without chimney extensions are numerically investigated.The present numerical simulations are validated by the purposely-designed experimental measurements on honeycombs with/without chimney.Good agreement between numerical simulation and experimental measurement is obtained.The influences of inclination angle and geometric parameters such as cell shape,streamwise and spanwise length are also numerically quantified.With the increment in inclination angle,the overall heat transfer rate decreases for the honeycombs with/without chimney.For honeycombs with the same void volume fraction but different cell shapes,there is little difference on the overall heat transfer rate.To enhance the natural convective heat transfer of honeycombs,these techniques including increasing the length of honeycomb in the streamwise/spanwise direction,increasing the thermal conductivity of hon-eycomb structure or adding a chimney extension may be helpful. | YANG XiaoHu YAN HongBin WANG WenBin JIN LiWen LU TianJian ICHIMIYA Koichi | 2015 | Science China(Technological Sciences)2015，58，8： | 1 |

| 12 | Directed evolution of a neutrophilic and mesophilic methanol dehydrogenase based on high-throughput and accurate measurement of formaldehyde显示文摘Methanol is a promising one-carbon feedstock for biomanufacturing,which can be sustainably produced from carbon dioxide and natural gas.However,the efficiency of methanol bioconversion is limited by the poor catalytic properties of nicotinamide adenine dinucleotide(NAD^(+))-dependent methanol dehydrogenase(Mdh)that oxidizes methanol to formaldehyde.Herein,the neutrophilic and mesophilic NAD^(+)-dependent Mdh from Bacillus stearothermophilus DSM 2334(Mdh_(Bs))was subjected to directed evolution for enhancing the catalytic activity.The combination of formaldehyde biosensor and Nash assay allowed high-throughput and accurate measurement of formaldehyde and facilitated efficient selection of desired variants.Mdh_(Bs)variants with up to 6.5-fold higher K_(cat)/K_(M)value for methanol were screened from random mutation libraries.The T153 residue that is spatially proximal to the substrate binding pocket has significant influence on enzyme activity.The beneficial T153P mutation changes the interaction network of this residue and breaks theα-helix important for substrate binding into two shortα-helices.Reconstructing the interaction network of T153 with surrounding residues may represent a promising strategy to further improve Mdh_(Bs),and this study provides an efficient strategy for directed evolution of Mdh. | Jin Qian Liwen Fan Jinxing Yang Jinhui Feng Ning Gao Guimin Cheng Wei Pu Wenjuan Zhou Tao Cai Shuang Li Ping Zheng Jibin Sun Depei Wang Yu Wang | 2023 | Synthetic and Systems Biotechnology2023，8，3： | 0 |
