1Anthropogenic emission inventories in China:a review显示文摘The development of reliable anthropogenic emission inventories is essential for both understanding the sources of air pollution and designing effective air-pollution-control measures in China. However, it is challenging to quantify emissions in China accurately, given the variety of contributing sources, the complexity of the technology mix and the lack of reliable measurements. Over the last two decades,tremendous efforts have been made to improve the accuracy of emission inventories, and significant improvements have been realized. More reliable statistics and survey-based data have been used to reduce the uncertainties in activity rates and technology distributions. Local emission factors and source profiles covering various sources have been measured and reported. Based on these local databases, improved emission inventory models have been developed for power plants, large industrial plants and the residential,transportation and agricultural sectors. In this paper, we review the progress that has been made in developing inventories of anthropogenic emissions in China. We first highlight the major updates that have been made to emission inventory models and the underlying data by source category. We then summarize the sector-based estimates of emissions of different species contained in current inventories. The progress that has been made in the development of model-ready emissions is also presented. Finally, we suggest future directions for further improving the accuracy of emission inventories in China.Meng Li Huan Liu Guannan Geng Chaopeng Hong Fei Liu Yu Song Dan Tong Bo Zheng Hongyang Cui Hanyang Man Qiang Zhang Kebin He 2017National Science Review2017,4,6:100
2A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s).QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China 2003Chinese Science Bulletin2003,48,10:121

4Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF.Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun 2018Science China(Life Sciences)2018,61,12:43
5The Chromosome-Level Reference Genome of Tea Tree Unveils Recent Bursts of Nonautonomous LTR Retrotransposons in Driving Genome Size Evolution显示文摘Dear Editor,The tea tree Camellia sinensis,a member of the genus Camellia in the Theaceae family,includes two major cultivated varieties,C.sinensis var.assamica(CSA\Assam type)and C.sinensis var.sinensis(CSS;Chinese type)(Ming and Bartholomew,2007).Due to the high economic importance of the tea tree,considerable efforts have been made to explore genetic basis of the biosynthesis of natural metabolites that determine health benefits and diverse tea flavors(Shi et al.,2011;Li et al.,2011;Li et al.,2015;Xia et aL,2017;Liu et al.,2019).Qun-Jie Zhang Wei L i Kui Li Hong Nan Cong Shi Yun Zhang Zhang-Yan Dai Yang-Lei Lin Xiao-Lan Yang Yan Tong Dan Zhang Cui Lu Li-Ying Feng Chen-Feng Wang Xiao-Xin Liu Jian-An Huang Wen-Kai Jiang Xing-Hua Wang Xing-Cai Zhang Evan E.Eichler Zhong-Hua Liu and Li-Zhi Gao 2020Molecular Plant2020,13,7:27

7Pathways of China's PM;air quality 2015–2060 in the context of carbon neutrality显示文摘Clean air policies in China have substantially reduced particulate matter(PM;) air pollution in recent years,primarily by curbing end-of-pipe emissions.However,reaching the level of the World Health Organization(WHO) guidelines may instead depend upon the air quality co-benefits of ambitious climate action.Here,we assess pathways of Chinese PM;air quality from 2015 to 2060 under a combination of scenarios that link global and Chinese climate mitigation pathways(i.e.global 2℃-and 1.5℃-pathways,National Determined Contributions(NDC) pledges and carbon neutrality goals) to local clean air policies.We find that China can achieve both its near-term climate goals(peak emissions) and PM;air quality annual standard(35 μg/m;) by 2030 by fulfilling its NDC pledges and continuing air pollution control policies.However,the benefits of end-of-pipe control reductions are mostly exhausted by 2030,and reducing PM;exposure of the majority of the Chinese population to below 10 μg/m;by 2060 will likely require more ambitious climate mitigation efforts such as China’ s carbon neutrality goals and global1.5℃-pathways.Our results thus highlight that China’s carbon neutrality goals will play a critical role in reducing air pollution exposure to the level of the WHO guidelines and protecting public health.Jing Cheng Dan Tong Qiang Zhang Yang Liu Yu Lei Gang Yan Liu Yan Sha Yu Ryna Yiyun Cui Leon Clarke Guannan Geng Bo Zheng Xiaoye Zhang Steven JDavis Kebin He 2021National Science Review2021,8,12:23
8Can acupuncture therapy reduce preoperative anxiety?A systematic review and meta-analysis显示文摘Background:Acupuncture therapy has shown promise for effectively relieving preoperative anxiety.Nevertheless,previous findings from randomized controlled trials(RCTs)are inconsistent and must be examined in detail.Objective:This study systematically evaluates the efficacy and safety of acupuncture therapy for preoperative anxiety as well as the quality of evidence supporting this application.Search strategy:The China National Knowledge Infrastructure Database,Wanfang Data Journal Database,Chinese Biomedical Literature Database,Chongqing VIP,Embase,Pub Med and Cochrane Library Databases were queried from their inception to 19,February 2020,using keywords such as“acupuncture therapy,”“preoperative”and“anxioty.”Manual searches expanded the search breadth and included conference abstracts and other reference lists.Inclusion criteria:RCTs were included in the current study if they contained a comparison between a group of anxiety patients that received acupuncture therapy and a control group that received sham acupuncture.Data extraction and analysis:Literature was reviewed,and various articles were selected using the Note Express 3.2.0 software.Two researchers independently screened and extracted data and evaluated the risk of bias in the included studies.The Rev Man 5.3 software was used for data aggregation and the Grades of Recommendation,Assessment,Development and Evaluation(GRADE)assessment was used to evaluate the quality of the study outcomes.Results:Twelve studies were included in the review,containing a total of 916 patients.Meta-analysis showed that,compared with the control group,patients who received acupuncture therapy had reduced State-Trait Anxiety Inventory Scale(STAI-S)score(mean difference[MD]=–9.07,95%confidence interval[CI][–13.19 to–4.96],P<0.0001)and Visual Analogue Scale(VAS)score(MD=–1.37,95%CI[–2.29 to–0.45],P=0.003).However,for the Hamilton Anxiety Scale(HAMA)score,there was no difference between the two groups(MD=–3.98,95%CI[–12.89 to 4.92],P=0.38).Further,the GRADE assessment demonstrated that the STAI-S was of moderate quality,the VAS of low quality and the HAMA of very low quality.Conclusion:Acupuncture therapy may be able to decrease anxiety in preoperative patients,but the results need to be further verified due to the small sample sizes and the low quality of evidence to date.Qiu-yu Tong Ran Liu Kun Zhang Yuan G ao Guang-wei Cui Wei-dong Shen 2021Journal of Integrative Medicine2021,19,1:15

11Meta-analysis of stapled hemorrhoidopexy vs LigaSure hemorrhoidectomy显示文摘AIM: To compare outcome of stapled hemorrhoidopexy (SH) vs LigaSure hemorrhoidectomy (LH) by a meta-analysis of available randomized controlled trials (RCTs). METHODS: Databases, including PubMed, EMBASE, the Cochrane Library, and the Science Citation Index updated to December 2012, were searched. The main outcomes measured were operating time, early postoperative pain, postoperative urinary retention and bleeding, wound problems, gas or fecal incontinence, anal stenosis, length of hospital stay, residual skin tags, prolapse, and recurrence. The meta-analysis was performed using the free software Review Manager. Differences observed between the two groups were expressed as the odds ratio (OR) with 95%CI. A fixedeffects model was used to pool data when statistical heterogeneity was not present. If statistical heterogeneity was present (P < 0.05), a random-effects model was used. RESULTS: The initial search identified 10 publica-tions. After screening, five RCTs published as full articles were included in this meta-analysis. Among the five studies, all described a comparison of the patient baseline characteristics and showed that there was no statistically significant difference between the two groups. Although most of the analyzed outcomes were similar between the two operative techniques, the operating time for SH was significantly longer than for LH (P < 0.00001; OR= -6.39, 95%CI: -7.68 -5.10). The incidence of residual skin tags and prolapse was significantly lower in the LH group than in the SH group [2/111 (1.8%) vs 16/105 (15.2%); P = 0.0004; OR= 0.17, 95%CI: 0.06-0.45). The incidence of recurrence after the procedures was significantly lower in the LH group than in the SH group [2/173 (1.2%) vs 13/174 (7.5%); P = 0.003; OR= 0.21, 95%CI: 0.07-0.59]. CONCLUSION: Both SH and LH are probably equally valuable techniques in modern hemorrhoid surgery. However, LigaSure might have slightly favorable immediate postoperative results and technical advantages.Jun Yang Pei-Jing Cui Hua-Zhong Han Da-Nian Tong 2013World Journal of Gastroenterology2013,19,29:12

13Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
14The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
15A Synthetic Photorespiratory Shortcut Enhances Photosynthesis to Boost Biomass and Grain Yield in Rice显示文摘Several photorespiratory bypasses have been introduced into plants and shown to improve photosynthesis by increasing chloroplastic C02 concentrations or optimizing energy balance.We recently reported that an engineered GOC bypass could increase photosynthesis and productivity in rice.However,the grain yield of GOC plants was unstable,fluctuating in different cultivation seasons because of varying seed setting rates.In this study,we designed a synthetic photorespiratory shortcut(the GCGT bypass)consisting of genes en-coding Oryza sativa glycolate oxidase and Escherichia coli catalase,glyoxylate carboligase,and tartronic semialdehyde reductase.The GCGT bypass was guided by an optimized chloroplast transit peptide that targeted rice chloroplasts and redirected 75% of carbon from glycolate metabolism to the Calvin cycle,identical to the native photorespiration pathway.GCGT transgenic plants exhibited significantly increased biomass production and grain yield,which were mainly attributed to enhanced photosynthesis due to increased chloroplastic C02 concentrations.Despite the increases in biomass production and grain yield,GCGT transgenic plants showed a reduced seed setting rate,a phenotype previously reported for the GOC plants.Integrative transcriptomic,physiological,and biochemical assays revealed that photosynthetic car-bohydrates were not transported to grains in an efficient manner,thereby reducing the seed setting rate.Taken together,our results demonstrate that the GCGT photorespiratory shortcut confers higher yield by promoting photosynthesis in rice,mainly through increasing chloroplastic C02 concentrations.Li-Min Wang Bo-Ran Shen Bo-Di Li Chuan-Ling Zhang Min Lin Pan-Pan Tong Li-Li Cui Zhi-Sheng Zhang Xin-Xiang Peng 2020Molecular Plant2020,13,12:11
16The chromosome-level reference genome assembly for Panax notoginseng and insights into ginsenoside biosynthesis显示文摘Panax notoginseng,a perennial herb of the genus Panax in the family Araliaceae,has played an important role in clinical treatment in China for thousands of years because of its extensive pharmacological effects.Here,we report a high-quality reference genome of P.notoginseng,with a genome size up to 2.66 Gb and a contig N50 of 1.12 Mb,produced with third-generation PacBio sequencing technology.This is the first chromosome-level genome assembly for the genus Panax.Through genome evolution analysis,we explored phylogenetic and whole-genome duplication events and examined their impact on saponin biosynthesis.We performed a detailed transcriptional analysis of P.notoginseng and explored genelevel mechanisms that regulate the formation of characteristic tubercles.Next,we studied the biosynthesis and regulation of saponins at temporal and spatial levels.We combined multi-omics data to identify genes that encode key enzymes in the P.notoginseng terpenoid biosynthetic pathway.Finally,we identified five glycosyltransferase genes whose products catalyzed the formation of different ginsenosides in P.notoginseng.The genetic information obtained in this study provides a resource for further exploration of the growth characteristics,cultivation,breeding,and saponin biosynthesis of P.notoginseng.Zhouqian Jiang Lichan Tu Weifei Yang Yifeng Zhang Tianyuan Hu Baowei Ma Yun Lu Xiuming Cui Jie Gao Xiaoyi Wu Yuru Tong Jiawei Zhou Yadi Song Yuan Liu Nan Liu Luqi Huang Wei Gao 2021Plant Communications2021,2,1:11
17Efficacy of chitosan and sodium alginate scaffolds for repair of spinal cord injury in rats显示文摘Spinal cord injury results in the loss of motor and sensory pathways and spontaneous regeneration of adult mammalian spinal cord neurons is limited. Chitosan and sodium alginate have good biocompatibility, biodegradability, and are suitable to assist the recovery of damaged tissues, such as skin, bone and nerve. Chitosan scaffolds, sodium alginate scaffolds and chitosan-sodium alginate scaffolds were separately transplanted into rats with spinal cord hemisection. Basso-Beattie-Bresnahan locomotor rating scale scores and electrophysiological results showed that chitosan scaffolds promoted recovery of locomotor capacity and nerve transduction of the experimental rats. Sixty days after surgery, chitosan scaffolds retained the original shape of the spinal cord. Compared with sodium alginate scaffolds-and chitosan-sodium alginate scaffolds-transplanted rats, more neurofilament-H-immunoreactive cells(regenerating nerve fibers) and less glial fibrillary acidic protein-immunoreactive cells(astrocytic scar tissue) were observed at the injury site of experimental rats in chitosan scaffold-transplanted rats. Due to the fast degradation rate of sodium alginate, sodium alginate scaffolds and composite material scaffolds did not have a supporting and bridging effect on the damaged tissue. Above all, compared with sodium alginate and composite material scaffolds, chitosan had better biocompatibility, could promote the regeneration of nerve fibers and prevent the formation of scar tissue, and as such, is more suitable to help the repair of spinal cord injury.Zi-ang Yao Feng-jia Chen Hong-li Cui Tong Lin Na Guo Hai-ge Wu 2018Neural Regeneration Research2018,13,3:11

19The 1470 nm diode laser with an intralesional fiber device:a proposed solution for the treatment of inflamed and infected keloids显示文摘Background:Keloids are the result of abnormal wound healing and often are subject to infections and recurrent inflammation.We present a study conducted with a 1470 nm diode laser using an intralesional optical fiber device for the treatment of inflamed keloid scars.We evaluate its efficacy as a novel alternative method to decrease keloid infection and inflammation.Methods:The patients who underwent 1470 nm laser treatment from February 2016 to February 2018 at the plastic and reconstructive surgery department of the Shanghai Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University with keloid accompanying serious local infection and fester were included.Patients took curative effect evaluation before and 1 year after the treatment.The test items included infection frequency in each year;pain,by visual analogue scale(VAS);itch,using VAS;quality of life(QOL),using QOL scale;and blood supply,using PeriCam PSI.Results:A total of 19 patients(mean age 35.21 years,range 11–66)with history of inflamed keloids with episodes of infection or abscess were enrolled.Patients underwent to a 1470 nm laser therapy for average of 1.16 times.After treatment,infection frequency and blood supply in keloids were reduced(p<0.001).Pain,itching,and QOL were improved(p<0.001).Conclusion:The present study shows that 1470 nm fiber laser treatment could improve inflamed keloids fairly well by decreasing inflammation,and a relative stabilization of collagen composition.Therefore,it is an effective minimally invasive scar therapy,but further studies are essential to confirm the present results.Ke Li Fabio Nicoli Wen Jing Xi Zheng Zhang Chunxiao Cui Ahmed Al-Mousawi Alberto Balzani Yun Tong Yixin Zhang 2019Burns & Trauma2019,7,1:8
20The gut microbial metabolite, 3,4-dihydroxyphenylpropionic acid, alleviates hepatic ischemia/reperfusion injury via mitigation of macrophage pro-inflammatory activity in mice显示文摘Hepatic ischemia/reperfusion injury(HIRI) is a serious complication that occurs following shock and/or liver surgery. Gut microbiota and their metabolites are key upstream modulators of development of liver injury. Herein, we investigated the potential contribution of gut microbes to HIRI.Ischemia/reperfusion surgery was performed to establish a murine model of HIRI. 16 S r RNA gene sequencing and metabolomics were used for microbial analysis. Transcriptomics and proteomics analysis were employed to study the host cell responses. Our results establish HIRI was significantly increased when surgery occurred in the evening(ZT12, 20:00) when compared with the morning(ZT0, 08:00);however, antibiotic pretreatment reduced this diurnal variation. The abundance of a microbial metabolite3,4-dihydroxyphenylpropionic acid was significantly higher in ZT0 when compared with ZT12 in the gut and this compound significantly protected mice against HIRI. Furthermore, 3,4-dihydroxyphenylpropionic acid suppressed the macrophage pro-inflammatory response in vivo and in vitro. This metabolite inhibits histone deacetylase activity by reducing its phosphorylation. Histone deacetylase inhibition suppressed macrophage pro-inflammatory activation and diminished the diurnal variation of HIRI. Our findings revealed a novel protective microbial metabolite against HIRI in mice. The potential underlying mechanism was at least in part, via 3,4-dihydroxyphenylpropionic acid-dependent immune regulation and histone deacetylase(HDAC) inhibition in macrophages.Rui Li Li Xie Lei Li Xiaojiao Chen Tong Yao Yuanxin Tian Qingping Li Kai Wang Chenyang Huang Cui Li Yifan Li Hongwei Zhou Neil Kaplowitz Yong Jiang Peng Chen 2022Acta Pharmaceutica Sinica B2022,12,1:8
