| 1 | Effectiveness of Inactivated COVID-19 Vaccines Against Symptomatic,Pneumonia,and Severe Disease Caused by the Delta Variant:Real World Study and Evidence—China,2021显示文摘Summary What is already known about this topic?Effectiveness of China’s 2 inactivated vaccines(BBIBPCorV and CoronaVac)against pre-Delta severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)variants ranged from 47%to over 90%,depending on the clinical endpoint,and with greater effectiveness against more severe coronavirus disease 2019(COVID-19).During an outbreak in Guangdong,inactivated vaccine effectiveness(VE)against the Delta variant was 70%for symptomatic infection and 100%for severe COVID-19.However,separate or combined VE estimates for the two inactivated vaccines against Delta are not available.What is added by this report?In an outbreak that started in a hospital,VEs of completed primary vaccination with inactivated COVID-19 vaccines against symptomatic COVID-19,COVID-19 pneumonia,and severe COVID-19 caused by the Delta variant were 51%,61%,and 82%.Completed primary vaccination reduced the risk of progressing from mild to moderate or severe COVID-19 by 74%.VE estimates for BBIBP-CorV and CoronaVac or combined vaccination were similar,and partial vaccination was ineffective.What are the implications for public health practice?Completed primary vaccination with either of the 2 inactivated COVID-19 vaccines reduces risk of symptomatic COVID-19,COVID-19 pneumonia,and severe COVID-19 caused by the Delta variant.Completion of the completed primary vaccination with two doses is necessary for protection from Delta. | Dan Wu Yanyang Zhang Lin Tang Fuzhen Wang Ying Ye Chao Ma Hui Zheng Wenzhou Yu Lei Cao Yifan Song Abuduwaili Reyimu Xiaoxiao Zhang Haifeng Wang Yifei Nie Mingxia Lu Muge Qi Jun Li Ruolin Wang Kaichao Yang Changshuang Wang Lawrence Everett Rodewald Geroge Fu Gao Zhijie An Zundong Yin | 2022 | China CDC weekly2022，4，4： | 7 |
| 2 | Changes in T lymphocyte subsets after severe traumatic brain injury显示文摘BACKGROUND: Besides local changes of cranial parenchymal cells, hemorrhage, etc., severe traumatic brain injuries also cause the changes of total body fluid and various functions, and the changes of lymphocytes and T lymphocyte subsets should be paid more attention to. OBJECTIVE: To reveal the changing laws of T lymphocyte subsets after severe traumatic brain injury, and compare with mild to moderate brain injury. DESIGN: A comparative observation. SETTINGS: Department of Neurosurgery, Longgang District Buji People's Hospital of Shenzhen City; Central Laboratory of Shenzhen Hospital of Prevention and Cure for Chronic Disease. PARTICIPANTS: All the subjects were selected from the Department of Neurosurgery, Longgang District Buji People's Hospital of Shenzhen City from August 2002 to August 2005. Thirty patients with severe brain injury, whose Glasgow coma score (GCS) was ≤ 8 points, were taken as the experimental group, including 21 males and 9 females, aging 16–62 years. Meanwhile, 30 patients with mild traumatic brain injury were taken as the control group (GCS ranged 14–15 points), including 18 males and 12 females, aging 15–58 years. All the subjects were in admission at 6 hours after injury, without disease of major organs before injury. Informed consents were obtained from all the patients or their relatives. METHODS: ① The T lymphocytes and the subsets in peripheral blood were detected with immunofluorescent tricolor flow cytometry at 1, 3, 7 and 14 days after injury in both groups. ② The conditions of pulmonary infections were observed at 4 days after injury. The differences of measurement data were compared with the t test. MAIN OUTCOME MEASURES: Changes of T lymphocytes subsets at 1–14 days after severe and mild or moderate traumatic injury. RESULTS: Finally, 28 and 25 patients with mild to moderate traumatic brain injury, whereas 25 and 21 patients with severe traumatic brain injury were analyzed at 7 and 14 days respectively, and the missed ones died due to the development of disease. ① Changes of T lymphocyte subsets: At 1 and 3 days after injury, CD3, CD4, CD8, CD4/CD8 began to decrease, whereas CD8 increased in the experimental group, which were very significantly different from those in the control group (t =2.77–3.26, P < 0.01), and began to recover at 7 days, which were significantly different from those in the control group (t = 2.06–2.24, P < 0.05), and generally recovered to the normal levels at 14 days (P > 0.05). ② Conditions of pulmonary infections: At 4 days after injury, the rate of pulmonary infection was significantly different between the experimental group and control group [73% (22/30), 0, χ2=37.29, P < 0.01]. CONCLUSION: Patients with severe traumatic brain injury suffer from damages of cellular immune function at early period (within 7 days), and they are easily to be accompanied by pulmonary infections. | Yulu Miao Mingxia Zhang Yulin Nie Wan Zhao Bin Huang Zhengming Jiang Shaoxiong Yu Zhibin Huang Hongjin Fu | 2007 | Neural Regeneration Research2007，2，2： | 7 |
| 3 | Quantitative analysis of Pb adsorption on sulfhydryl-modified biochar显示文摘Biochar is an effective absorbent for remediating heavy metal contaminated soil,but functional optimization is still needed to improve its performance in field application.Here,we characterized the physical structures and surface chemical properties of raw wood biochar and palm biochar(WB and PB)and the corresponding sulfhydryl-modified biochar(SWB and SPB).Their adsorption capacity for Pb was evaluated by combining thermodynamic and kinetic adsorption at 0.01 mol/L KCl and corresponding model simulation.The results demonstrated successful grafting of sulfhydryl groups onto the biochar,which dramatically reduced the specific surface area(SSA)and pore volume of biochar.The pKa in the surface complexation model(SCM)indicated similar proton affinity between sulfhydryl groups and original functional groups on the biochar.SCM could satisfactorily fit the Pb adsorption behaviors,and model analysis revealed that Pb tended to be adsorbed on low-proton affin-ity sites at low pH,but high-proton affinity sites became dominant in Pb adsorption with increasing pH and adsorbed almost all Pb ions at pH>7.0.Besides,the Pb adsorption density of SWB and SPB was improved by 8.86 and 3.64 folds relative to that of WB and PB,respectively.Over 90% of initially added Pb ions were removed in 1440 and 720 min by raw and sulfhydryl-modified biochar,respectively,indicating that sulfhydryl modification accelerated the Pb adsorption of biochar.These results suggest that site density,SSA and pore structure of biochar play crucial roles in heavy metal adsorption,and sulfhydryl modification may improve the performance of biochar in remediating heavy metal contaminated soil. | Juan Xiong Mengge Zhou Chenchen Qu Daohai Yu Chang Chen Mingxia Wang Wenfeng Tan | 2021 | Biochar2021，3，1： | 5 |

| 6 | CRISPR-Cas adaptive immune systems in Sulfolobales:genetic studies and molecular mechanisms显示文摘CRISPR-Cas systems provide the small RNA-based adaptive immunity to defend against invasive genetic elements in archaea and bacteria.Organisms of Sulfolobales,an order of thermophilic acidophiles belonging to the Crenarchaeotal Phylum,usually contain both type I and typeⅢCRISPR-Cas systems.Two species,Saccharolobus solfataricus and Sulfolobus islandicus,have been important models for CRISPR study in archaea,and knowledge obtained from these studies has greatly expanded our understanding of molecular mechanisms of antiviral defense in all three steps:adaptation,expression and crRNA processing,and interference.Four subtypes of CRISPR-Cas systems are common in these organisms,including I-A,I-D,Ⅲ-B,andⅢ-D.These cas genes form functional modules,e.g.,all genes required for adaptation and for interference in the I-A immune system are clustered together to form aCas and i Cas modules.Genetic assays have been developed to study mechanisms of adaptation and interference by different CRISPR-Cas systems in these model archaea,and these methodologies are useful in demonstration of the protospacer-adjacent motif(PAM)-dependent DNA interference by I-A interference modules and multiple interference activities byⅢ-B Cmr systems.Ribonucleoprotein effector complexes have been isolated for SulfolobalesⅢ-B andⅢ-D systems,and their biochemical characterization has greatly enriched the knowledge of molecular mechanisms of these novel antiviral immune responses. | Zhenxiao Yu Suping Jiang Yuan Wang Xuhui Tian Pengpeng Zhao Jianan Xu Mingxia Feng Qunxin She | 2021 | Science China(Life Sciences)2021，64，5： | 2 |

| 10 | Gelation Phenomenon During Crystallization of Cefpiramide Sodium显示文摘Unlike the adverse eff ect caused by the gelation during crystallization process, gelation of cefpiramide sodium was found to provide ideal product properties, such as a larger and more regular crystal shape. The causes of the gelation phenomenon and the mechanism of gel-crystal transition during the crystallization of cefpiramide sodium were both investigated in this work. The gel was formed due to the strapping of the solvents by the networks of cefpiramide sodium molecules. The whole gel-crystal transition process was divided into the following three stages:(1) when the temperature decreased, the system reached a metastable-state gelation;(2) the initial microcrystal in the gel grew slowly because of the low supersaturation;and (3) the gel fi nally disappeared, and a larger and more regular crystal was formed. The Hansen solubility parameters were used to analyze the eff ects of the solvents on this gelation;the analysis results can serve as guidance for solvent screening in the actual production process. | Yu Wei Qiuxiang Yin Mingxia Guo Ling Zhou Ying Bao Yongfan Yang | 2019 | Transactions of Tianjin University2019，25，4： | 1 |

| 13 | Engineering surface oxygen vacancy of mesoporous CeO_(2) nanosheets assembled microspheres for boosting solar-driven photocatalytic performance显示文摘Surface oxygen vacancy defects of mesoporous CeO_(2)nanosheets assembled microspheres(D-CeO_(2))are engineered by polymer precipitation,hydrothermal and surface hydrogenation strategies.The resultant D-CeO_(2)with a main pore diameter of 9.3 nm has a large specific surface area(~102.3 m^(2)/g)and high thermal stability.The mesoporous nanosheets assembled microsphere structure prevents the nanosheets from aggregation,which is beneficial to effective mass transfer and shortens the migration distance of charge carriers.After surface hydrogenation,the photoresponse extends to long wavelength region,combing with the band gap from 2.63 eV reduced to 2.39 eV.Under AM 1.5 G radiation,the photocatalytic degradation rate of tetracycline(TC)can be up to 99.99%,which is three times as high as that of pristine CeO_(2)microspheres.The excellent solar-driven photocatalytic performance can be attributed to the efficient surface oxygen vacancy engineering and the mesoporous nanosheets assembled microsphere structure,which narrows the band gap,shortens the migration distance of carriers,promotes the spatial separation of photogenerated electron-hole pairs and favors mass transfer.The strategy provides new insights for fabricating other high-efficient oxide photocatalysts. | Decai Yang Yachao Xu Kai Pan Chuanxin Yu Jiaxing Wu Mingxia Li Fan Yang Yang Qu Wei Zhou | 2022 | Chinese Chemical Letters2022，33，1： | 0 |
| 14 | Examination of Huntington's disease in a Chinese family显示文摘We report brain imaging and genetic diagnosis in a family from Wuhan,China,with a history of Huntington's disease.Among 17 family members across three generations,four patients(II2,II6,III5,and III9) show typical Huntington's disease,involuntary dance-like movements.Magnetic resonance imaging found lateral ventricular atrophy in three members(II2,II6,and III5).Moreover,genetic analysis identified abnormally amplified CAG sequence repeats(> 40) in two members(III5 and III9).Among borderline cases,with clinical symptoms and brain imaging features of Huntington's disease,two cases were identified(II2 and II6),but shown by mutation analysis for CAG expansions in the important transcript 15 gene,to be non-Huntington's disease.Our findings suggest that clinical diagnosis of Huntington's disease requires a combination of clinical symptoms,radiological changes,and genetic diagnosis. | Mingxia Yu Xiaogai Li Sanyun Wu Ji Shen Jiancheng Tu | 2014 | Neural Regeneration Research2014，9，4： | 0 |
| 15 | Synthesis of a ternary amide LixKy(NH2)x+y and a novel Li3K(NH2)4–xMgH2 combination system for hydrogen storage显示文摘The ternary amides LiK2(NH2)3, LiK(NH2)2, and Li3 K(NH2)4 are successfully synthesized by ball milling mixtures of LiNH2 and KNH2, and the hydrogen storage properties of Li3K(NH2)4–xMgH2(x = 1, 2, 3,4) are systematically investigated. The Li3K(NH2)4–2 Mg H2 sample displays optimized hydrogen storage properties, releasing 6.37 wt% of hydrogen in a two-stage reaction with an onset temperature of 60 °C.The first dehydrogenation stage exhibits good reaction kinetics and thermodynamic properties because of a lower activation energy and appropriate enthalpy change. After full dehydrogenation at 130 °C, the Li3K(NH2)4–2 MgH2 sample absorbs 3.80 wt% of H2 below 160 °C in a variable temperature hydrogenation mode. Mechanistic investigations indicate that Li3 K(NH2)4 reacts with Mg H2 to produce Mg(NH2)2, LiH,and KH during ball milling. In the heating process, Mg(NH2)2 first reacts with Li H to form Li2 Mg2 N3 H3 and Li NH2, while KH works as a catalyst, and then, KH reacts with Li2Mg2N3H3 and Li NH2 to generate a new K-containing compound. | Chao Li Changlong Li Meiqiang Fan Haichao Chen Kangying Shu Yu Zhang Mingxia Gao Yongfeng Liu Hongge Pan | 2019 | Journal of Energy Chemistry2019，28，8： | 0 |
| 16 | Plasmon Bi in-situ anchored on BiOCl nanosheets assembled microspheres towards optimized photothermal-photocatalytic performance显示文摘Interface engineering is of great importance to improve the photocatalytic performance.Herein,in-situ formation plasmon Bi/BiOCl nanosheets assembled heterojunction microspheres are fabricated via facile reductive solvothermal approach.The aldehyde group in the DMF structure is used to exert the weak reducing property of the solvent and thus strip out the metal Bi in BiOCl.The metal Bi is anchored on surface of BiOCl firmly due to in-situ formation engineered interface,which could realize efficient charge transfer channel.The resultant Bi/BiOCl heterojunctions assemblies with narrow bandgap of 3.05 eV and mesoporous structure extend the photoresponse to visible light region and could provide sufficient surface active sites.The visible-light-driven photocatalytic degradation of high-toxic norfloxacin for Bi/BiOCl heterojunctions is up to 95.5%within 20 min,representing several times that of pristine BiOCl nanosheets and the physical mixture.It is attributed to the in-situ formation of Bi/BiOCl heterojunctions and surface plasmon resonance(SPR)effect of plasmon Bi promoting charge transfer,and the obvious photothermal effect promoting the photocatalytic reaction,which are verified by experimental and density functional theory(DFT)calculations.This strategy provides ideal perspectives for fabricating metal/semiconductor heterojunctions photocatalysts with high-performance. | Dongxue Song Mingxia Li Fan Yang Menghan Yu Zhenzi Li Jie Chen Xiaoshuang Zhang Wei Zhou | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 17 | Sorting nexin 3 exacerbates doxorubicin-induced cardiomyopathy via regulation of TFRC-dependent ferroptosis显示文摘The clinical utilization of doxorubicin(Dox)in various malignancies is restrained by its major adverse effect:irreversible cardiomyopathy.Extensive studies have been done to explore the prevention of Dox cardiomyopathy.Currently,ferroptosis has been shown to participate in the incidence and development of Dox cardiomyopathy.Sorting Nexin 3(SNX3),the retromer-associated cargo binding protein with important physiological functions,was identified as a potent therapeutic target for cardiac hypertrophy in our previous study.However,few study has shown whether SNX3 plays a critical role in Dox-induced cardiomyopathy.In this study,a decreased level of SNX3 in Dox-induced cardiomyopathy was observed.Cardiac-specific Snx3 knockout(Snx3-cKO)significantly alleviated cardiomyopathy by downregulating Dox-induced ferroptosis significantly.SNX3 was further demonstrated to exacerbate Dox-induced cardiomyopathy via induction of ferroptosis in vivo and in vitro,and cardiac-specific Snx3 transgenic(Snx3-cTg)mice were more susceptible to Dox-induced feroptosis and cardiomyopathy.Mechanistically,SNX3 facilitated the recycling of transferrin 1 receptor(TFRC)via direct interaction,disrupting iron homeostasis,increasing the accumulation of iron,triggering ferroptosis,and eventually exacerbating Dox-induced cardiomyopathy.Overall,these findings established a direct SNX3-TFRC-ferroptosis positive regulatory axis in Dox-induced cardiomyopathy and suggested that targeting SNX3 provided a new effective therapeutic strategy for Dox-induced cardiomyopathy through TFRCdependentferroptosis. | Wenjing Yu Yuehuai Hu Zhiping Liu Kaiteng Guo Dinghu Ma Mingxia Peng Yuemei Wang Jing Zhang Xiaolei Zhang Panxia Wang Jiguo Zhang Peiqing Liu Jing Lu | 2023 | Acta Pharmaceutica Sinica B2023，13，12： | 0 |
| 18 | The human-derived novel gut commensal Luoshenia tenuis regulates body weight and food intake in mice显示文摘Many studies have revealed that gut microbes modulate host metabolism.In this study,we characterized the therapeutic effects of a novel gut commensal Luoshenia tenuis against host metabolic disorders.First,by in silico analysis,we demonstrated that the L.tenuis was prevalent in the gut microbiomes of healthy humans but were depleted specifically in obesity cohorts.Further in vitro cultivation revealed that L.tenuis produced short chain fatty acids that were verified to modulate host metabolism and some other volatile metabolites to benefit hosts by anti-inflammation and anti-tumor.Second,gavage of the L.tenuis significantly decreased the body weight gain and food intake of high-fat diet-feeding C57BL/6J mice,which was in parallel with the changed expression level of genes related to satiety and feeding behavior.We then performed the gavage trial using diet induced obese mice,and it revealed that the administration of L.tenuis alleviated significantly the abnormal glucose and lipid metabolisms and reduced the inflammatory response.In summary,this study revealed a previously-unknown human gut commensal microbe that benefited host metabolism,and set the stage for the development of novel next-generation probiotic applicable for treatment of obesity and related metabolic disorders. | Yu Jiang Mengxuan Du Lisheng Xie Minzhi Jiang Yaokun Zhang Mingxia Bi Chang Liu Hongwei Liu Shuangjiang Liu | 2024 | Food Science and Human Wellness2024，13，2： | 0 |
| 19 | Low glucose metabolite 3-phosphoglycerate switches PHGDH from serine synthesis to p53 activation to control cell fate显示文摘Glycolytic intermediary metabolites such as fructose-1,6-bisphosphate can serve as signals,controlling metabolic states beyond energy metabolism.However,whether glycolytic metabolites also play a role in controlling cell fate remains unexplored.Here,we find that low levels of glycolytic metabolite 3-phosphoglycerate(3-PGA)can switch phosphoglycerate dehydrogenase(PHGDH)from cataplerosis serine synthesis to pro-apoptotic activation of p53.PHGDH is a p53-binding protein,and when unoccupied by 3-PGA interacts with the scaffold protein AXIN in complex with the kinase HIPK2,both of which are also p53-binding proteins.This leads to the formation of a multivalent p53-binding complex that allows HIPK2 to specifically phosphorylate p53-Ser46 and thereby promote apoptosis.Furthermore,we show that PHGDH mutants(R135W and V261M)that are constitutively bound to 3-PGA abolish p53 activation even under low glucose conditions,while the mutants(T57A and T78A)unable to bind 3-PGA cause constitutive p53 activation and apoptosis in hepatocellular carcinoma(HCC)cells,even in the presence of high glucose.In vivo,PHGDH-T57A induces apoptosis and inhibits the growth of diethylnitrosamine-induced mouse HCC,whereas PHGDH-R135W prevents apoptosis and promotes HCC growth,and knockout of Trp53 abolishes these effects above.Importantly,caloric restriction that lowers whole-body glucose levels can impede HCC growth dependent on PHGDH.Together,these results unveil a mechanism by which glucose availability autonomously controls p53 activity,providing a new paradigm of cell fate control by metabolic substrate availability. | Yu-Qing Wu Chen-Song Zhang Jinye Xiong Dong-Qi Cai Chen-Zhe Wang Yu Wang Yan-Hui Liu Yu Wang Yiming Li Jian Wu Jianfeng Wu Bin Lan Xuefeng Wang Siwei Chen Xianglei Cao Xiaoyan Wei Hui-Hui Hu Huiling Guo Yaxin Yu Abdul Ghafoor Changchuan Xie Yaying Wu Zheni Xu Cixiong Zhang Mingxia Zhu Xi Huang Xiufeng Sun Shu-Yong Lin Hai-Long Piao Jianyin Zhou Sheng-Cai Lin | 2023 | Cell Research2023，33，11： | 0 |
| 20 | Tuning coordination environment of iron ions to ensure ultra-high pseudocapacitive capability in iron oxide显示文摘The mechanism governing the pseudocapacitive lithium storage behavior is one of the most critical unsolved issues in conversion-type anodes for lithium-ion batteries.In this work,we,for the first time,demonstrate that the pseudocapacitive capability of iron oxide-based anodes is closely associated with the electronic structures of iron ions.As proof of concept,the introduction of amorphization,nitrogen doping,oxygen vacancies reduces the coordination of iron ions and contributes significantly to the pseudocapacitive lithium storage capability of iron oxide,reaching up to 96%of the specific capacity at 1 mV·s^(−1).Due to the significantly modulated coordination environment,the 3d electrons of Fe(II)are delocalized with increased spin state and the energy band gap is narrowed,accompanied by an upshift of Fermi energy.The redox activity and carrier mobility of iron oxides are substantially increased,which substantially enhance the exchange current density and thereby improve the pseudocapacitive capability of iron oxide. | Wubin Du Chenhui Yan Mingxi Gao Jian Chen Panyu Gao Xuebin Yu Yinzhu Jiang Wenping Sun Yongfeng Liu Mingxia Gao Shibo Xi Hongge Pan | 2023 | Nano Research2023，16，5： | 0 |
