3Washed microbiota transplantation vs.manual fecal microbiota transplantation:clinical findings,animal studies and in vitro screening显示文摘Fecal microbiota transplantation(FMT)by manual preparation has been applied to treat diseases for thousands of years.However,this method still endures safety risks and challenges the psychological endurance and acceptance of doctors,patients and donors.Population evidence showed the washed microbiota preparation with microfiltration based on an automatic purification system followed by repeated centrifugation plus suspension for three times significantly reduced FMT-related adverse events.This washing preparation makes delivering a precise dose of the enriched microbiota feasible,instead of using the weight of stool.Intraperitoneal injection in mice with the fecal microbiota supernatant obtained after repeated centrifugation plus suspension for three times induced less toxic reaction than that by the first centrifugation following the microfiltration.The toxic reactions that include death,the change in the level of peripheral white blood cells,and the proliferation of germinal center in secondary lymphoid follicles in spleen were noted.The metagenomic next-generation sequencing(NGS)indicated the increasing types and amount of viruses could be washed out during the washing process.Metabolomics analysis indicated metabolites with pro-inflammatory effects in the fecal microbiota supernatant such as leukotriene B4,corticosterone,and prostaglandin G2 could be removed by repeated washing.Near-infrared absorption spectroscopy could be served as a rapid detection method to control the quality of the washingprocess.In conclusion,this study for the first time provides evidence linking clinical findings and animal experiments to support that washed microbiota transplantation(WMT)is safer,more precise and more quality-controllable than the crude FMT by manual.Ting Zhang Gaochen Lu Zhe Zhao Yafei Liu Quan Shen Pan Li Yaoyao Chen Haoran Yin Huiquan Wang Cicilia Marcella Bota Cui Lei Cheng Guozhong Ji Faming Zhang 2020Protein & Cell2020,11,4:44
4Engineering a New Chloroplastic Photorespiratory Bypass to In crease Photosynthetic Efficiency and Productivity in Rice显示文摘Over the past few years, three photorespiratory bypasses have been introduced into plants, two of which led to observable in creases in photos yn thesis and biomass yield. However, most of the experiments were carried out using Arabidopsis under controlled environmental conditions, and the increases were only observed under low-light and short-day conditions. In this study, we designed a new photorespiratory bypass (called GOC bypass), characterized by no reducing equivalents being produced during a complete oxidation of glycolate into CO2 catalyzed by three rice-self-originating enzymes, i.e., glycolate oxidase, oxalate oxidase, and catalase. We successfully established this bypass in rice chloroplasts using a multi-gene assembly and transformation system. Transgenic rice plants carrying GOC bypass (GOC plants) showed significant increases in photosynthesis efficiency, biomass yield, and nitrogen content, as well as several other CO2-enriched phe no types under both greenhouse and field conditions .Grain yield of GOC plants varied depending on seeding season and was increased significantly in the spring. We further demonstrated that GOC plants had significant advantages under high-light conditions and that the improvements in GOC plants resulted primarily from a photosynthetic CO2-concentrating effect rather than from improved energy balance. Taken together, our results reveal that engineering a newly designed chloroplastic photorespiratory bypass could increase photosynthetic efficiency and yield of rice plants grown in field conditions, particularly under high light.Bo-Ran Shen Li-Min Wang Xiu-Ling Lin Zhen Yao Hua-Wei Xu Cheng-Hua Zhu Hai-Yan Teng Li-Li Cui E.-E.

5Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy.Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen 2021Cancer Communications2021,41,11:29
6Study on Relationship between Microstructure of Active Phase and HDS Performance of Sulfided Ni-Mo Catalysts: Effect of Metal Loading显示文摘Six Ni-Mo catalysts with different metal contents were prepared and characterized by N2 adsorption and X-ray diffractometry. The active phase microstructure of these catalysts was examined by the Raman spectroscopy, temperatureprogrammed reduction(TPR), X-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy. Hydrodesulfurization(HDS) activity of catalyst samples were analyzed in a flow fixed-bed microreactor. The sulfidation degree of Mo and the length of the MoS2 slab slightly increased with the amount of metal loaded following sulfidation. This small change is attributed to polymolybdate species observed in all the oxidized catalysts. Weak metal-support interactions, as determined by the TPR technique, increased the NiSx sulfidation phase and MoS2 slab stacking. The HDS activity of the catalyst samples increased with the number of active sites. For high metal loading catalysts, their HDS activity was nearly identical because the sulfur atoms cannot easily approach active sites. This change is caused by the large number of stacked layers in the MoS2 slabs as well as the decrease in the specific surface area and pore volume of the catalyst samples with an increasing metal loading.Guo Rong Shen Benxian Fang Xiangchen Sun Jin Peng Chong Cui Xiaoli 2014China Petroleum Processing & Petrochemical Technology2014,16,2:21
7A step metallogenetic model for gold deposits in the northwestern Shandong Peninsula, China显示文摘Based on our study of the nature and variation of mineralization-controlling faults in their deep extension and the spatial distribution of gold orebodies in the northwestern Shandong Peninsula (NSP), here we propose that the gold deposits in the Jiaojia gold belt are controlled by listric faults and the gold deposits in the NSP are controlled by extensional fault system. We also suggest that there is a multiple mineralization space in the deep part of the NSP gold belt. As steps or benches occur along the deep extention of the listric fault where its dipping angle changes from steep to gentle, a number of gold deposits are correspondingly distributed as a steplike pattern, which is named as a step metallogenetic model for gold deposits in the NSP. The gold deposits in Shandong Peninsula were formed in the Cretaceous when the crust in the region experienced extention and thinning following the strong collision between North China Plate and Yangtze Plate during the Triassic. Crust anataxis, fluid remobilization, and extention-detachement of the crust are the leading factors for the gold mineralization.SONG MingChun YI PiHou XU JunXiang CUI ShuXue SHEN Kun JIANG HongLi YUAN WenHua WANG HuaJiang 2012Science China Earth Sciences2012,55,6:21
8High-speed maneuvering target detection approach based on joint RFT and keystone transform显示文摘Increasing the integration time is an effective method to improve small maneuvering target detection performance in radar applications.However,range migration and Doppler spread caused by maneuvering target motion during the integration time make it difficult to improve the coherent accumulation of target's energy and detection performance.In this study,a new method based on Radon Fourier transform(RFT) and keystone transform(KT) for high-speed maneuvering target detection is proposed.The proposed algorithm utilizes second-order KT to correct the range curvature,and the improved dechirping method to compensate for the Doppler spread.RFT is then used to correct the range walk for target coherent detection.The method is capable of correcting the range migration and the time-varied Doppler frequency of the target without knowing its velocity and acceleration.The advantage of the proposed method is that it can increase the coherent integration time and improve detection performance under the condition of Doppler frequency ambiguity.Compared with the second-order RFT algorithm,the computational burden of the proposed method is greatly reduced under the premise that the two methods have similar estimation accuracy of range,velocity and acceleration.Numerical experiments demonstrate the validity of the proposed algorithm.TIAN Jing CUI Wei SHEN Qing WEI ZiXiang WU SiLiang 2013Science China(Information Sciences)2013,56,6:19

11Exosome-mediated transfer of miR-1290 promotes cell proliferation and invasion in gastric cancer via NKD1显示文摘Currently, exosomes rich in RNAs and proteins are regarded as vital mediators of intercellular communication. Here, we aimed to explore the effects of exosomal miR-1290 in gastric cancer (GC) and understand its mechanism of action on GC progression. We first isolated exosomes from serum samples of GC patients and healthy people and characterized them by transmission electron microscopy. Then, we examined the expression level of miR-1290 contained in the exosomes by quantitative reverse-transcription polymerase chain reaction and found that exosomal miR-1290 was overexpressed in GC patients and cell lines. Promotion of proliferation, migration, and invasiveness of GC cells was noted after they were incubated with the isolated miR-1290-rich exosomes compared with incubation with a negative control. Furthermore, we predicted that naked cuticle homolog 1 (NKD1) mRNA is a direct target of miR-1290 and confirmed their interaction by a dual luciferase reporter assay. NKD1 overexpression attenuated the stimulatory effects of miR-1290 on GC cells. Collectively, our results suggest that exosomal miR-1290 enhances GC cell proliferation and invasion by targeting NKD1 mRNA and downregulating NKD1 expression. A better understanding of this process may facilitate the development of novel therapeutic agents for GC.Jiying Huang Manru Shen Meizhu Yan Ying Cui Zhenjun Gao Xin Meng 2019Acta Biochimica et Biophysica Sinica2019,51,9:19
12Agriculture Green Development: a model for China and the world显示文摘Realizing sustainable development has become a global priority.This holds,in particular,for agriculture.Recently,the United Nations launched the Sustainable Development Goals(SDGs),and the Nineteenth National People’s Congress has delivered a national strategy for sustainable development in China—realizing green development.The overall objective of Agriculture Green Development(AGD)is to coordinate'green'with'development'to realize the transformation of current agriculture with high resource consumption and high environmental costs into a green agriculture and countryside with high productivity,high resource use efficiency and low environmental impact.This is a formidable task,requiring joint efforts of government,farmers,industry,educators and researchers.The innovative concept for AGD will focus on reconstructing the whole crop-animal production and food production-consumption system,with the emphasis on high thresholds for environmental standards and food quality as well as enhanced human well-being.This paper addresses the significance,challenges,framework,pathways and potential solutions for realizing AGD in China,and highlights the potential changes that will lead to a more sustainable agriculture in the future.Proposals include interdisciplinary innovations,whole food chain improvement and regional solutions.The implementation of AGD in China will provide important implications for the countries in developmental transition,and contribute to global sustainable development.Jianbo SHEN Qichao ZHU Xiaoqiang JIAO Hao YING Hongliang WANG Xin WEN Wen XU Tingyu LI Wenfeng CONG Xuejun LIU Yong HOU Zhenling CUI Oene OENEMA William JDAVIES Fusuo ZHANG 2020Frontiers of Agricultural Science and Engineering2020,7,1:18

14Expression Detection of DMRTs and Two sox9 Genes in Takifugu rubripes (Tetraodontidae, Vertebrata)显示文摘Sex determination and sex differentiation are important phenomena in fish, but the mechanisms of sex determination in Takifugu rubripes are poorly understood. In our study, the expression patterns of genes for DMRTs (DMRT1, DMRT2 and DMRT3), sox9a and sox9b in T. rubripes tissues were verified with the Reverse Transcription (RT)-PCR detection. It is showed that DMRT1 expressions in testis and ovaries were much lower, and no expressions were found in muscle, blood and tailfin. However, expressions for DMRT2 and DMRT3 were not found in the tissues stated above. Transcripts of sox9a were detected in muscle, fin, ovary and testis, but not in blood, whereas sox9b expression was only detected in ovary. The expression patterns of DMRTs, sox9a and sox9b in T. rubripes gonads suggest that these genes may not be sex-specific.SHEN Xueyan CUI Jianzhou YANG Guanpin GONG Qingli GU Qianqun 2007Journal of Ocean University of China2007,6,2:15
15Can 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
16Dermoscopy in China: current status and future prospective显示文摘Objective: Dermoscopy is a useful technique for improving the diagnostic accuracy of various types of skin disorders. In China, dermoscopy has been widely accepted, and domestic researchers have made tremendous progress in the field of dermoscopy. The main purpose of this review is to summarize the current status of dermoscopy in China and identify its future directions. Data sources: Articles included in this review were obtained by searching the following databases: Wanfang, China National Knowledge Infrastructure, PubMed, and the Web of Science. We focused on research published before 2019 with keywords including dermoscopy, dermoscopic, dermoscope and trichoscopy. Study selection: A total of 50 studies were selected. Of these studies, 20 studies were in Chinese and 30 in English, research samples of all the studies were collected from Chinese populations. Results: Since 2000, more than 380 articles about dermoscopy have been published in domestic or foreign journals. Dermoscopy can improve the diagnostic accuracy of neoplastic diseases, evaluating the therapeutic effect of treatment, and determining the treatment endpoint, and it can also assist in the differential diagnosis of inflammatory diseases and in the assessment of the severity of the disease. In addition, researches about the applications of dermoscopy during surgical treatment have been published. Training courses aiming to improve the diagnostic ability of dermatologists, either face-to-face or online, have been offered. The Chinese Skin Image Database, launched in 2017 as a work platform for dermatologists, has promoted the development of dermoscopy in China. Computer-aided diagnostic systems based on the Chinese population are ready for use. In the future, cooperation, resource sharing, talent development, image management, and computer-aided diagnosis will be important directions for the development of dermoscopy in China. Conclusion: Dermoscopy has been widely used and developed in China, however, it still needs to address more challenges in the future.Xue Shen Rui-Xing Yu Chang-Bing Shen Cheng-Xu Li Yan Jing Ya-Jie Zheng Zi-Yi Wang Ke Xue Feng Xu Jian-Bin Yu Ru-Song Meng Yong Cui 2019Chinese Medical Journal2019,,17:15
17Comparative pharmacokinetics of six major compounds in normal and insomnia rats after oral administration of Ziziphi Spinosae Semen aqueous extract显示文摘Ziziphi Spinosae Semen(ZSS),a traditional Chinese medicine,is used in clinics for the treatment of insomnia in China and other Asian countries.Herein,we described for the first time a comparative pharmacokinetics study of the six major compounds of ZSS in normal control(NC)and para-chlorophenylalanine(PCPA)-induced insomnia model(IM)rats that were orally administered the aqueous extract of ZSS.An ultra-high-performance liquid chromatography coupled with quadrupole orbitrap mass(UHPLC-Q-Orbitrap-MS)method was developed and validated for the simultaneous determination of coclaurine,magnoflorine,spinosin,6000-feruloylspinosin,jujuboside A(JuA),and jujuboside B(JuB)in ZSS in rat plasma.The established approach was successfully applied to a comparative pharmacokinetic study.The systemic exposures of spinosin and 6000-feruloylspinosin were decreased in the IM group compared to the NC group,while plasma clearance(CL)was significantly increased.The Tmax values of JuA and JuB in IM rats were significantly lower than those in NC rats.The T1/2 of JuA in the IM group was significantly accelerated.The pharmacokinetic parameters of coclaurine and magnoflorine were not evidently affected between the two groups.These results indicate that the pathological state of insomnia altered the plasma pharmacokinetics of spinosin,6000-feruloylspinosin,JuA,and JuB in the ZSS aqueous extract,providing an experimental basis for the role of ZSS in insomnia treatment.The comparative pharmacokinetics-based UHPLC-Q-Orbitrap-MS using full-scan mode can therefore provide a reliable and suitable means for the screening of potentially effective substances applied as quality markers of ZSS.Chenhui Du Yan Yan Chenxi Shen Xiaofang Cui Xiangping Pei Xuemei Qin 2020Journal of Pharmaceutical Analysis2020,10,4:14

19Breakdown Behavior of Eutectic Carbide in High Speed Steel During Hot Compression显示文摘The evolution of eutectic carbide in as-cast M2 high speed steel was investigated with hot compression test and metallographic examination.Initial rodlike or irregular eutectic carbides were broken into smaller particles during hot deformation by thermomechanical disintegration,while diffusion-controlled phase transformation was not remarkable.Combining with numerical simulation,the relationship between breakdown ratio of carbide network and deformation parameters was obtained.Strain was the most important driving force to shatter eutectic carbides and disperse products.Furthermore,critical strain values were obtained,beyond which carbide network disappeared,and fractured carbides kept a stable profile and they were deformed with matrix coordinately.A higher temperature or lower strain rate resulted in a lower critical strain.ZHOU Bin SHEN Yu CHEN Jun CUI Zhen-shan 2011Journal of Iron and Steel Research(International)2011,18,1:12
