| 1 | Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders:executive summary and 2019 update of the management of high-risk population显示文摘Aim Cerebrovascular disease is the leading cause of death and disability in China,causing a huge burden among patients and their families.Hence,stroke prevention is critical,especially in the high-risk population.Here,we present the evidence-based guideline suitable for the Chinese population.Methods Literature search of PubMed and Cochrane library(from January 1964 to June 2019)was done.After thorough discussion among the writing group members,recommendations were listed and summarised.This guideline was reviewed and discussed by the fellow writing committees of the Chinese Stroke Association’s Stroke.Results This evidence-based guideline was written in three parts:controlling the risk factors of stroke,utilisation of antiplatelet agents and assessing the risks of first-ever stroke.All recommendations were listed along with the recommending classes and levels of evidence.Conclusions This guideline provides recommendations for primary prevention of cerebrovascular disease among high-risk population in China.Controlling related risk factors,appropriately using antiplatelet agents,assessing the risk of developing first-ever stroke should help reduce the rate of cerebrovascular disease in China. | Yilong Wang Shangrong Han Haiqiang Qin Huaguang Zheng Bin Jiang Yong Cao Yuan Gao Ling Guan Qian Jia Yong Jiang Yuming Jiao Shuya Li Yapeng Li Zixiao Li Wei Liu Xiaojuan Ru Dongling Sun Haixin Sun Penglian Wang Tingting Wang Lixia Zong Lei Guo Xuewei Xie Yuming Xu Yuyuan Xu Xiaomeng Yang Yingying Yang Mengyuan Zhou Wenzhi Wang Chinese Stroke Association Stroke Council Guideline Writing Committee | 2020 | Stroke & Vascular Neurology2020，5，3： | 11 |
| 2 | Research on High Altitude Remote Sensing Building Segmentation Based on Improved U-Net Algorithm显示文摘Building extraction from high resolution remote sensing image is a key technology of digital city construction[14].In order to solve the problems of low efficiency and low precision of traditional remote sensing image segmentation,an improved U-Net network structure is adopted in this paper.Firstly,in order to extract efficient building characteristic information,FPN structure was introduced to improve the ability of integrating multi-scale information in U-Net model;Secondly,to solve the problem that feature information weakens with the deepening of network depth,an efficient residual block network is introduced;Finally,In order to better distinguish the target area and background area in the image and improve the precision of building target edge detection,the cross entropy loss and Dice loss were linearly combined and weighted.Experimental results show that the algorithm can improve the image segmentation effect and improve the image accuracy by 18%. | SHI Mengyuan GAO Junchai | 2021 | Instrumentation2021，8，4： | 6 |
| 3 | Discrimination of False Negative Results in RT-PCR Detection of SARS-CoV-2 RNAs in Clinical Specimens by Using an Internal Reference显示文摘Reverse transcription-polymerase chain reaction(RT-PCR)is an essential method for specific diagnosis of SARS-CoV-2 infection.Unfortunately,false negative test results are often reported.In this study,we attempted to determine the principal causes leading to false negative results of RT-PCR detection of SARS-CoV-2 RNAs in respiratory tract specimens.Multiple sputum and throat swab specimens from 161 confirmed COVID-19 patients were tested with a commercialfluorescent RT-PCR kit targeting the ORF1 ab and N regions of SARS-CoV-2 genome.The RNA level of a cellular housekeeping gene ribonuclease P/MRP subunit p30(RPP30)in these specimens was also assessed by RT-PCR.Data for a total of 1052 samples were retrospectively re-analyzed and a strong association between positive results in SARS-CoV-2 RNA tests and high level of RPP30 RNA in respiratory tract specimens was revealed.By using the ROC-AUC analysis,we identified Ct cutoff values for RPP30 RT-PCR which predicted false negative results for SARS-CoV-2 RT-PCR with high sensitivity(95.03%–95.26%)and specificity(83.72%–98.55%)for respective combination of specimen type and ampli-fication reaction.Using these Ct cutoff values,false negative results could be reliably identified.Therefore,the presence of cellular materials,likely infected host cells,are essential for correct SARS-CoV-2 RNA detection by RT-PCR in patient specimens.RPP30 could serve as an indicator for cellular content,or a surrogate indicator for specimen quality.In addition,our results demonstrated that false negativity accounted for a vast majority of contradicting results in SARS-CoV-2 RNA test by RT-PCR. | Yafei Zhang Changtai Wang Mingfeng Han Jun Ye Yong Gao Zhongping Liu Tengfei He Tuantuan Li Mengyuan Xu Luping Zhou Guizhou Zou Mengji Lu Zhenhua Zhang | 2020 | Virologica Sinica2020，35，6： | 5 |

| 5 | Downregulation of HNRNPK in human cancer cells inhibits lung metastasis显示文摘Background: Lung cancer frequently occurs in the clinic, leading to poor prognosis and high mortality. Markers for early diagnosis of lung cancer are scarce, and further potential therapeutic targets are also urgently needed.Method: We established a new mouse model in which the specific gene HNRNPK(heterogeneous nuclear ribonucleoprotein K) was downregulated after administration of doxycycline. The lung metastatic nodules were investigated using bioluminescence imaging, micro-CT, and autopsy quantification.Results: Compared with the short hairpin negative control group, less lung metastatic nodules were formed in the short hairpin RNA group.Conclusion: Downregulation of HNRNPK in cancer cells can inhibit lung metastasis. | Mengyuan Li Wenlong Zhang Xingjiu Yang Hongfei Liu Lin Cao Weisha Li Le Wang Guoxin Zhang Ran Gao | 2019 | Animal Models and Experimental Medicine2019，2，4： | 2 |
| 6 | Towards a bright future:The versatile applications of organic solar cells显示文摘Due to the mechanical flexibility,light weight,aesthetics,absorption tunability and environmental friendliness,organic solar cells(OSCs)have superior application potential over their inorganic counterparts including silicon and perovskite solar cells(PSCs).Thanks to these benefits,the past decade have witnessed the rapid growth of flexible OSCs,semitransparent OSCs and indoor OSCs.In this progress report,we firstly overview the recent advance of the applications of the three promising OSCs.Subsequently,we sketch the critical points for the three classes of OSCs and highlight the efforts paid by the research community to address these issues.Besides,we discuss some popular strategies to afford great performance of each kind of OSC,respectively,and underline the corresponding breakthrough directions.Last but not least,we present the remaining challenges for advancing the commercial applications of these three classes of OSCs. | Junjiang Wu Mengyuan Gao Yubo Chai Pengke Liu Bo Zhang Junwei Liu Long Ye | 2021 | Materials Reports(Energy)2021，1，4： | 1 |
| 7 | Evaluation of Ecological Environment Quality of Typical Forest Parks显示文摘Forest tourist areas have an excellent ecological environment,which is conducive to people's physical and mental health.In this study,Fuzhou National Forest Park and Wuying National Forest Park were selected as typical representatives of the southern and northern forest parks,respectively,which were compared by qualitative and quantitative research methods from such five aspects as air quality,climate quality,water environment quality,acoustic environment quality and biological population in some forest areas.The results showed that Fuzhou National Forest Park has a concentration of negative oxygen ions much higher than Wuying National Forest Park,and is thus more conducive to people's health;and it has the characteristics of warm and comfortable climate throughout the year and high biodiversity,but the noise is 4.35 db higher than Wuying National Forest Park,and the water quality is slightly poorer than that of Wuying National Forest Park.And its DO value is about 3.89 smaller in autumn than in summer.In Wuying National Forest Park,the concentration of negative oxygen ions is 53.6% lower than Fuzhou National Forest Park,but it is also above the national standard.The climate is only comfortable in June-August,and is colder or cooler in other months.The water quality is better than that of Fuzhou National Forest Park.In particular,the PH value is about 0.38 lower than that of Fuzhou National Forest Park.It has its own unique biological characteristics.The number of tourists in summer is higher,resulting in higher noise in summer than in autumn.The two forest parks in the north and the south are both good places for people to relax and enjoy. | Dongmei ZHANG Shuzhen PENG Weijun ZHAO Mengyuan GAO Junqing HAN | 2019 | Agricultural Biotechnology2019，8，5： | 1 |

| 9 | Consensus on potential biomarkers developed for use in clinical tests for schizophrenia显示文摘Background Schizophrenia is a serious mental illness affecting approximately 20 million individuals globally.Both genetic and environmental factors contribute to the illness.If left undiagnosed and untreated,schizophrenia results in impaired social function,repeated hospital admissions,reduced quality of life and decreased life expectancy.Clinical diagnosis largely relies on subjective evidence,including self-reported experiences,and reported behavioural abnormalities followed by psychiatric evaluation.In addition,psychoses may occur along with other conditions,and the symptoms are often episodic and transient,posing a significant challenge to the precision of diagnosis.Therefore,objective,specific tests using biomarkers are urgently needed for differential diagnosis of schizophrenia in clinical practice.Aims We aimed to provide evidence-based and consensus-based recommendations,with a summary of laboratory measurements that could potentially be used as biomarkers for schizophrenia,and to discuss directions for future research.Methods We searched publications within the last 10 years with the following keywords:‘schizophrenia’,‘gene’,‘inflammation’,‘neurotransmitter’,‘protein marker’,‘gut microbiota’,‘pharmacogenomics’and‘biomarker’.A draft of the consensus was discussed and agreed on by all authors at a round table session.Results We summarised the characteristics of candidate diagnostic markers for schizophrenia,including genetic,inflammatory,neurotransmitter,peripheral protein,pharmacogenomic and gut microbiota markers.We also proposed a novel laboratory process for diagnosing schizophrenia in clinical practice based on the evidence summarised in this paper.Conclusions Further efforts are needed to identify schizophrenia-specific genetic and epigenetic markers for precise diagnosis,differential diagnosis and ethnicity-specific markers for the Chinese population.The development of novel laboratory techniques is making it possible to use these biomarkers clinically to diagnose disease. | Ping Lin Junyu Sun Xiaoyan Lou Dan Li Yun Shi Zhenhua Li Peijun Ma Ping Li Shuzi Chen Weifeng Jin Shuai Liu Qing Chen Qiong Gao Lili Zhu Jie Xu Mengyuan Zhu Mengxia Wang Kangyi Liang Ling Zhao Huabin Xu Ke Dong Qingtian Li Xunjia Cheng Jinghong Chen Xiaokui Guo | 2022 | General Psychiatry2022，35，1： | 1 |
| 10 | H_(4)SiW_(12)O_(40)-catalyzed cyclization of epoxides/aldehydes and sulfonyl hydrazides: An efficient synthesis of 3,4-disubstituted 1H-pyrazoles显示文摘A simple and efficient method for the synthesis of pyrazoles through a silicotungstic acid (H_(4)SiW_(12)O_(40))-catalyzed cyclization of epoxides/aldehydes and sulfonyl hydrazides has been developed. Various epoxides/aldehydes were smoothly reacted with sulfonyl hydrazides to furnish regioselectivity 3,4-disubstituted 1H-pyrazoles. The application of such an earth-abundant, readily accessible, and nontoxic catalyst provides a green approach for the construction of 3,4-disubstituted 1H-pyrazoles. A plausible reaction mechanism has been proposed on the basis of control experiments, GC-MS and DFT calculations. | Guoping Yang Xuanjie Xie Mengyuan Cheng Xiaofei Gao Xiaoling Lin Ke Li Yuanyuan Cheng Yufeng Liu | 2022 | Chinese Chemical Letters2022，33，3： | 1 |
| 11 | The nuclear cytokine IL-37a controls lethal cytokine storms primarily via IL-1R8-independent transcriptional upregulation of PPARγ显示文摘Cytokine storms are crucial in the development of various inflammatory diseases,including sepsis and autoimmune disorders.The immunosuppressive cytokine INTERLEUKIN(IL)-37 consists of five isoforms(IL-37a-e).We identified IL-37a as a nuclear cytokine for the first time.Compared to IL-37b,IL-37a demonstrated greater efficacy in protecting against Toll-like receptor-induced cytokine hypersecretion and lethal endotoxic shock.The full-length(FL)form of IL-37a and the N-terminal fragment,which is processed by elastase,could translocate into cell nuclei through a distinctive nuclear localization sequence(NLS)/importin nuclear transport pathway.These forms exerted their regulatory effects independent of the IL-1R8 receptor by transcriptionally upregulating the nuclear receptor peroxisome proliferator-activated receptor(PPARγ).This process involved the recruitment of the H3K4 methyltransferase complex WDR5/MLL4/C/EBPβand H3K4me1/2 to the enhancer/promoter of Pparg.The receptor-independent regulatory pathway of the nuclear IL-37a–PPARγaxis and receptor-dependent signaling by secreted IL-37a maintain homeostasis and are potential therapeutic targets for various inflammatory diseases,including sepsis. | Rongfei Wei Xiao Han Mengyuan Li Yuan Ji Lianfeng Zhang Maria-Ioanna Christodoulou Najwa Jameel Hameed Aga Caiyan Zhang Ran Gao Jiangning Liu Jinrong Fu Guoping Lu Xiaojun Xiao Xiaoyu Liu Ping-Chang Yang Iain B.McInnes Ying Sun Peisong Gao Chuan Qin Shau-Ku Huang Yufeng Zhou Damo Xu | 2023 | Cellular & Molecular Immunology2023，20，12： | 0 |
| 12 | Magnetoresistance anomaly in Fe_(5)GeTe_(2)homo-junctions induced by its intrinsic transition显示文摘Two-dimensional van der Waals(2D vdW)magnets have attracted great attention recently and possess the unprecedented advantages of incorporating high-quality vdW heterostructures and homostructures into spintronic devices,and exploring various physical phenomena or technologies.Among them,Fe_(5)GeTe_(2)(F5GT)has ferromagnetic order close to room temperature,however the magnetic properties near its intrinsic transitions and F5GT-based 2D devices remain mostly unexplored.Here,we systematically demonstrate the peculiar magnetic properties of Fe_(5)GeTe_(2)nanoflakes near its intrinsic transition temperature(Tp)which is far lower than its Curie temperature(TC)of~265 K,and firstly discover anomalous magnetoresistance effect in F5GT homo-junctions by magneto-transport measurements.The strongest anomalous Hall effect occurs around Tp which is located in a temperature range from 130 to 160 K for the F5GT nanoflakes with different thicknesses.Furthermore,negative magnetoresistance(N-MR)and butterfly-shaped magnetoresistance(B-MR)are observed in F5GT homo-junction devices,and they appeared only in an intermediate temperature range from 110 to 160 K,noticeably showing the maxima near the T_(p)rather than the lowest temperature.Our experimental results clearly reveal the significant influence of intrinsic transitions on magnetic properties of F5GT and magnetoresistance effect in F5GT homo-junction devices,which imply a new strategy to achieve highperformance 2D spintronic devices by tuning intrinsic magnetic or structural transitions in 2D vdW magnets. | Ruijie Zhao Yanfei Wu Shaohua Yan Xinjie Liu He Huang Yang Gao Mengyuan Zhu Jianxin Shen Shipeng Shen Weifeng Xu Zeyu Zhang Liyuan Zhang Jingyan Zhang Xinqi Zheng Hechang Lei Ying Zhang Shouguo Wang | 2023 | Nano Research2023，16，7： | 0 |
| 13 | A generic approach yields organic solar cells with enhanced efficiency and thermal stability显示文摘The use of deuterium are critical for promoting the fundamental understanding of aggregate materials and their new functions.Particularly,the solution structure of conjugated polymers can be hardly resolved without deuteration.However,studies about the isotopic effects of casting solvents on the aggregated structures of photovoltaic polymers and their bulk-heterojunction blends are deficient.Here,the impact of deuterated solvents on the thermal behavior,aggregated structures,and device performance of photovoltaic polymers is clearly delineated for the first time by multiple techniques.The enhanced π-π stacking order of photovoltaic polymers is highly relevant to their relatively poor miscibility with deuterated solvents.Benefiting from higher crystallinity and optimized morphology of deuterated solvents processed films,the devices are able to achieve better efficiency and notable improvement in thermal stability.Our results highlight the isotopic effects of solvents on the aggregated structure of conjugated polymer systems and reveal the potential of innovative approaches to fabricate thermally stable high-efficiency solar cells. | Mengyuan Gao Kai Zhang Chunyong He Hanqiu Jiang Xiong Li Qingchun Qi Kangkang Zhou Yu Chen Wenchao Zhao Long Ye | 2023 | Aggregate2023，4，2： | 0 |
| 14 | Advances and prospective in thermally stable nonfullerene polymer solar cells显示文摘Polymer solar cells(PSCs)featuring nonfullerene acceptors have attracted a great deal of attention in the research community.Exposure of these active layers to sunlight during operation demands excellent thermal stability.Optimizing PSCs often requires a step of thermal annealing,while long-term annealing often places a constraint on their stable operation at elevated temperature and results in a progressive loss of photovoltaic performance.Hence,it is crucial to understand and control the fundamental affecting factors on the thermal stability of nonfullerene PSCs.This review highlights the relationships between microstructure and thermal stability of PSCs and summarizes promising strategies to push this technology toward the level of practical application.Finally,we present the current challenges and prospective of this research area,intending to advance the practical applications of stable PSCs based on nonfullerene acceptors. | Long Ye Mengyuan Gao Jianhui Hou | 2021 | Science China Chemistry2021，64，11： | 0 |
| 15 | 8.30%Efficiency P3HT-based all-polymer solar cells enabled by a miscible polymer acceptor with high energy levels and efficient electron transport显示文摘P3HT stands out from numerous polymer donors owing to the merits of low cost and high scalability of synthesis.However,the photovoltaic performance of P3HT-based blends lags significantly behind the state-of-the-art systems,especially for all-polymer solar cells(APSCs) that generally show efficiency of around 3%–4% due to the lack of matched polymer acceptors.Herein,a polymer acceptor,named IDTBTC8-CN,was designed and synthesized with indacenodithiophene(IDT) and mono-cyano(CN)-substituted benzothiadiazole(BT-CN) as building blocks.Introducing a CN group endowed the polymer with decreased bandgap,and apparent n-type charge transport character despite the relatively high energy levels.Additionally,IDTBTC8-CN showed largely improved miscibility with P3HT,compared with that of BT-based control polymer IDTBTC8.The high miscibility between P3HT and IDTBTC8-CN as well as the amorphous aggregation behavior of IDTBTC8-CN enabled a broad manipulation room for the blend film to acquire favorable morphology.Eventually,a champion efficiency of 8.30% was achieved,in sharp contrast to that of the IDTBTC8-based system(1.21%).Such efficiency is a new record for P3HT-based APSCs reported so far.Moreover,P3HT:IDTBTC8-CN blend film also exhibited excellent mechanical robustness.This study implies the guidance of molecular design of the polymer acceptors and morphology control for P3HT-based APSCs. | Ziqi Liang Jiangting He Bin Zhao Mengyuan Gao Yu Chen Long Ye Miaomiao Li Yanhou Geng | 2023 | Science China Chemistry2023，66，1： | 0 |
| 16 | Therapeutic application of chick early amniotic fluid: effective rescue of acute myocardial ischemic injury by intravenous administration显示文摘Myocardial regeneration has been considered a promising option for the treatment of adult myocardial injuries.Previously,a chick early amniotic fluid(ceAF)preparation was shown to contain growth-related factors that pro-moted embryonic growth and cellular proliferation,though the nature of the components within ceAF were not fully defined.Here we tested whether this ceAF preparation is similarly effective in the promotion of myocardial regen-eration,which could provide an alternative therapeutic for intervening myocardial injury.In this study,a myocardial ischemic injury model was established in adult mice and pigs by multiple research entities,and we were able to show that ceAF can efficiently rescue damaged cardiac tissues and markedly improve cardiac function in both experimental models through intravenous administration.ceAF administration increased cell proliferation and improved angio-genesis,likely via down-regulation of Hippo-YAP signaling.Our data suggest that ceAF administration can effectively rescue ischemic heart injury,providing the key functional information for the further development of ceAF for use in attenuating myocardial injury. | Baiping Cui Yufan Zheng Xiang Gao Lihong Zhang Borui Li Jia Chen Xinyan Zhou Mengyuan Cai Wenrui Sun Yuting Zhang Keejong Chang Jiayi Xu Fuyin Zhu Yan Luo Tao Sun Jin Qian Ning Sun | 2022 | Cell Regeneration2022，11，1： | 0 |
| 17 | Spatial Distribution Characteristics of Forest Parks in Shandong Province显示文摘The spatial distribution characteristics of forest parks in Shandong Province were studied using geographical concentration index,Gini coefficient,and ArcGIS analysis software.The results show that the forest parks in Shandong Province are concentrated in the province and in the five subregions,and the equilibrium degree of the distribution is low.The density of forest parks in Shandong Province is high in eastern Shandong and central Shandong but low in western Shandong.The number of forest parks in the eastern coastal areas of Shandong Province is larger than the number of forest parks in the inland areas of Shandong Province. | Zhao Weijun Peng Shuzhen Liu Xiaomei Zhang Dongmei Han Junqing Gao Mengyuan Wang Chenqiu | 2019 | Meteorological and Environmental Research2019，10，5： | 0 |
| 18 | High T_(g) Polymer Insulator Yields Organic Photovoltaic Blends with Superior Thermal Stability at 150℃显示文摘Record-breaking organic solar cells(OSCs)based on blends of polymer donors and small molecule acceptors often show undesirable degradati on,which severely precludes their practical use.Herei n,we demonstrate a facile and cost-effective approach to con struct thermally stable OSCs at 150℃ by incorporating a small amount of a polymer insulator polyacenaphthylene(PAC)with high glass-transition temperature over 230℃ into polymer:acceptor blends.The model PTB7-Th:EH-IDTBR blend with 10 wt%PAC maintained above 85%of its initial efficiency upon continuous heating at 150℃ for over 800 h,while the efficiency of the blend without PAC sharply dropped by 70%after-300 h.Owing to high miscibility with acceptors,PAC confines the motion of the acceptor molecules and suppresses the acceptor crystallization at elevated temperatures,leading to significantly improved stability.Importantly,the effectiveness of this blending approach was also validated in many other OSC systems,showing great potential for achieving high-performance thermally stable electronics. | Fei Chen Ying Zhang Qi Wang Mengyuan Gao Nigel Kirby Zhongxiang Peng Yunfeng Deng Miaomiao Li Long Ye | 2021 | Chinese Journal of Chemistry2021，39，9： | 0 |
| 19 | Anti-apoptotic protein BCL-XL as a therapeutic vulnerability in gastric cancer显示文摘Background: New therapeutic targets are needed to improve the outcomes for gastric cancer(GC) patients with advanced disease. Evasion of programmed cell death(apoptosis) is a hallmark of cancer cells and direct induction of apoptosis by targeting the pro-survival BCL2 family proteins represents a promising therapeutic strategy for cancer treatment. Therefore, understanding the molecular mechanisms underpinning cancer cell survival could provide a molecular basis for potential therapeutic interventions. Method: Here we explored the role of BCL2L1 and the encoded anti-apoptotic BCL-XL in GC. Using Droplet Digital PCR(ddPCR) technology to investigate the DNA amplification of BCL2L1 in GC samples and GC cell lines, the sensitivity of GC cell lines to selective BCL-XL inhibitors A1155463 and A1331852, pan-inhibitor ABT-263, and VHL-based PROTAC-BCL-XL was analyzed using(CellTiter-Glo) CTG assay in vitro. Western Blot(WB) was used to detect the protein expression of BCL2 family members in GC cell lines and the manner in which PROTAC-BCL-XL kills GC cells. Coimmunoprecipitation(Co-IP) was used to investigate the mechanism of A1331852 and ABT-263 kills GC cell lines. DDPCR, WB, and real-time PCR(RTPCR) were used to investigate the correlation between DNA, RNA, protein levels, and drug activity. Results: The functional assay showed that a subset of GC cell lines relies on BCL-XL for survival. In gastric cancer cell lines, BCL-XL inhibitors A1155463 and A1331852 are more sensitive than the pan BCL2 family inhibitor ABT-263, indicating that ABT-263 is not an optimal inhibitor of BCL-XL. VHL-based PROTAC-BCL-XL DT2216 appears to be active in GC cells. DT2216 induces apoptosis of gastric cancer cells in a time-and dose-dependent manner through the proteasome pathway. Statistical analysis showed that the BCL-XL protein level predicts the response of GC cells to BCL-XL targeting therapy and BCL2L1 gene CNVs do not reliably predict BCL-XL expression.Conclusion: We identified BCL-XL as a promising therapeutic target in a subset of GC cases with high levels of BCL-XL protein expression. Functionally, we demonstrated that both selective BCL-XL inhibitors and VHL-based PROTAC BCL-XL can potently kill GC cells that are reliant on BCL-XL for survival. However, we found that BCL2L1 copy number variations(CNVs) cannot reliably predict BCL-XL expression, but the BCL-XL protein level serves as a useful biomarker for predicting the sensitivity of GC cells to BCL-XL-targeting compounds. Taken together, our study pinpointed BCL-XL as potential druggable target for specific subsets of GC. | Yumin Wei Liping Zhang Chao Wang Zefeng Li Mingjie Luo Guomin Xie Xingjiu Yang Mengyuan Li Shuyue Ren Dongbing Zhao Ran Gao Jia-Nan Gong | 2023 | Animal Models and Experimental Medicine2023，6，3： | 0 |
| 20 | Demonstration of safety characteristics and effects on gut microbiota of Lactobacillus gasseri HMV18显示文摘Human normal flora is a source of probiotics.The safety characteristics of a specific isolate determine its application in foods or drugs.The food-borne-pathogen antagonist strain Lactobacillus gasseri HMV18 is one of the isolates from normal human flora.In this work,we assessed the in vitro pH tolerance,bile tolerance,biogenic amine production,mucin utilization,and safety of in vivo administration to mice to evaluate general health,organ-body weight index,organ histopathological change,whether L.gasseri HMV18 can colonize in the gut or modulate the gut microbiota after oral administration.The results suggest that L.gasseri HMV18 can tolerate pH 3 for 2 h,3%bile for 3 h,biogenic amine negative,mucin usage negative,does not encode verified toxins,and cause no visible change in mice's organs.L.gasseri HMV18 might not colonize in mice's gut,but can significantly affect the structure of gut microbiota.A bibliographical survey suggested that there were as few as 8 opportunistic infection cases from 1984 to 2022 and that the possibility for L.gasseri to cause infection is relatively low.Therefore,this work provides a basis for the foods or drugs application of L.gasseri HMV18 and gives a map of experiments for the safety assessment of probiotics. | Xianxian Jia Miaomiao Jia Xiang Gao Xiang Li Mengyuan Wang Shengqiang Du Rui Huang Xiaotong Li Jun Zhang Shujin Li Chunling Ma Yan Zhang Bin Cong | 2024 | Food Science and Human Wellness2024，13，2： | 0 |
