6Comparison of Modified Mohr-Coulomb Model and Bai-Wierzbicki Model for Constructing 3D Ductile Fracture Envelope of AA6063显示文摘Ductile fracture of metal often occurs in the plastic forming process of parts.The establishment of ductile fracture criterion can effectively guide the selection of process parameters and avoid ductile fracture of parts during machining.The 3D ductile fracture envelope of AA6063-T6 was developed to predict and prevent its fracture.Smooth round bar tension tests were performed to characterize the flow stress,and a series of experiments were conducted to characterize the ductile fracture firstly,such as notched round bar tension tests,compression tests and torsion tests.These tests cover a wide range of stress triaxiality(ST)and Lode parameter(LP)to calibrate the ductile fracture criterion.Plasticity modeling was performed,and the predicted results were compared with corresponding experimental data to verify the plasticity model after these experiments.Then the relationship between ductile fracture strain and ST with LP was constructed using the modified Mohr-Coulomb(MMC)model and Bai-Wierzbicki(BW)model to develop the 3D ductile fracture envelope.Finally,two ductile damage models were proposed based on the 3D fracture envelope of AA6063.Through the comparison of the two models,it was found that BW model had better fitting effect,and the sum of squares of residual error of BW model was 0.9901.The two models had relatively large errors in predicting the fracture strain of SRB tensile test and torsion test,but both of the predicting error of both two models were within the acceptable range of 15%.In the process of finite element simulation,the evolution process of ductile fracture can be well simulated by the two models.However,BW model can predict the location of fracture more accurately than MMC model.Jianye Gao Tao He Yuanming Huo Miao Song Tingting Yao Wanbo Yang 2021Chinese Journal of Mechanical Engineering2021,34,2:6

8Effectiveness and safety of Chinese herbal medicines for hepatitis B virus-related acute-on-chronic liver failure:study protocol for a multicenter randomized controlled trial显示文摘OBJECTIVE:To conduct a multicenter randomized controlled trial of the efficacy of standardized Chinese herbal medicines(CHMs)against acuteon-chronic liver failure(ACLF)and provide reproducible and high-level evidence for clinical practice.METHODS:This is a prospective,multicenter,centrally randomized controlled trial.Patients diagnosed with hepatitis B virus-related ACLF(n=510)will be allocated to the standard medical therapy or CHM group at a 1∶1 ratio.Two CHMs will be used on the basis of the traditional Chinese medicine syndrome:Liangxue Jiedu granules for excess syndromes and Yiqi Jiedu granules for deficiency syndromes.The primary outcome is transplant-free survival at week 12.The secondary outcomes are(a)transplant-free survival at week 24,(b)liver function as assessed using the model for end-stage liver disease score at week 12,(c)liver function as assessed using the Child-Pugh score at week 12,and(d)the incidence of complications at week 12.DISCUSSION:The effectiveness and safety of CHM formulations will be assessed following treatment for ACLF.TRIAL REGISTRATION:The trial was registered at Clinical Trials.gov(NCT03577938)on June 24,2018.Zhang Ning Zhou Chao Wang Lifu He Tingting Wang Yao Wang Yan Bai Yunfeng Li Jun Xiao Xiaohe Gong Man 2020Journal of Traditional Chinese Medicine2020,40,6:5
9Terahertz wavefront shaping with multi-channel polarization conversion based on all-dielectric metasurface显示文摘Polarization manipulation of electromagnetic wave or polarization multiplexed beam shaping based on metasurfaces has been reported in various frequency bands.However,it is difficult to shape the beam with multi-channel polarization conversion in a single metasurface.Here,we propose a new method for terahertz wavefront shaping with multi-channel polarization conversion via all-silicon metasurface,which is based on the linear shape birefringence effect in spatially interleaved anisotropic meta-atoms.By superimposing the eigen-and non-eigen-polarization responses of the two kinds of meta-atoms,we demonstrate the possibility for high-efficiency evolution of several typical polarization states with two independent channels for linearly polarized waves.The measured polarization conversion efficiency is higher than 70%in the range of 0.9–1.3 THz,with a peak value of 89.2%at 1.1 THz.In addition,when more other polarization states are incident,combined with the integration of sub-arrays,we can get more channels for both polarization conversion and beam shaping.Simulated and experimental results verify the feasibility of this method.The proposed method provides a new idea for the design of terahertz multi-functional metadevices.JIE LI CHENGLONG ZHENG JITAO LI GUOCUI WANG JINGYU LIU ZHEN YUE XUANRUO HAO YUE YANG FUYU LI TINGTING TANG YATING ZHANG YAN ZHANG JIANQUAN YAO 2021Photonics Research2021,9,10:5
10TPGS/hyaluronic acid dual-functionalized PLGA nanoparticles delivered through dissolving microneedles for markedly improved chemo-photothermal combined therapy of superficial tumor显示文摘Nanoparticles(NPs)have shown potential in cancer therapy,while a single administration conferring a satisfactory outcome is still unavailable.To address this issue,the dissolving microneedles(DMNs)were developed to locally deliver functionalized NPs with combined chemotherapy and photothermal therapy(PTT).α-Tocopheryl polyethylene glycol succinate(TPGS)/hyaluronic acid(HA)dualfunctionalized PLGA NPs(HD10 NPs)were fabricated to co-load paclitaxel and indocyanine green.HD10 NPs significantly enhanced the cytotoxicity of low-dose paclitaxel because of active and mitochondrial targeting by HA and TPGS,respectively.PTT could further sensitize tumor cells toward chemotherapy by promoting apoptosis into the advanced period,highly activating caspase 3 enzyme,and significantly reducing the expression of survivin and MMP-9 proteins.Further,the anti-tumor effects of HD10 NPs delivered through different administration routes were conducted on the 4 T1 tumorbearing mice.After a single administration,HD10 NPs delivered with DMNs showed the best antitumor effect when giving chemotherapy alone.As expected,the anti-tumor effect was profoundly enhanced after combined therapy,and complete tumor ablation was achieved in the mice treated with DMNs and intra-tumor injection.Moreover,DMNs showed better safety due to moderate hyperthermia.Therefore,the DMNs along with combined chemo-photothermal therapy provide a viable treatment option for superficial tumors.Tingting Peng Yao Huang Xiaoqian Feng Chune Zhu Shi Yin Xinyi Wang Xuequn Bai Xin Pan Chuanbin Wu 2021Acta Pharmaceutica Sinica B2021,11,10:4
11The role of China's terrestrial carbon sequestration 2010-2060 in offsetting energy-related CO_(2) emissions显示文摘Energy consumption dominates annual CO_(2) emissions in China.It is essential to significantly reduce CO_(2) emissions from energy consumption to reach national carbon neutrality by 2060,while the role of terrestrial carbon sequestration in offsetting energy-related CO_(2) emissions cannot be underestimated.Natural climate solutions(NCS),including improvements in terrestrial carbon sequestration,represent readily deployable options to offset anthropogenic greenhouse gas emissions.However,the extent to which China’s terrestrial carbon sequestration in the future,especially when target-oriented managements(TOMs)are implemented,can help to mitigate energy-related CO_(2) emissions is far from certain.By synthesizing available findings and using several parameter-sparse empirical models that have been calibrated and/or fitted against contemporary measurements,we assessed China’s terrestrial carbon sequestration over 2010-2060 and its contribution to offsetting national energy-related CO_(2) emissions.We show that terrestrial C sequestration in China will increase from 0.375±0.056(mean±standard deviation)Pg C yr^(-1) in the 2010s to 0.458±0.100 Pg C yr^(-1)under RCP2.6 and 0.493±0.108 Pg C yr^(-1) under the RCP4.5 scenario in the 2050s,when TOMs are implemented.The majority of carbon sequestration comes from forest,accounting for 67.8-71.4%of the total amount.China’s terrestrial ecosystems can offset 12.2-15.0%and 13.4-17.8%of energy-related peak CO_(2) emissions in 2030 and 2060,respectively.The implementation of TOMs contributes 11.9%of the overall terrestrial carbon sequestration in the 2020s and 23.7%in the 2050s.The most likely strategy to maximize future NCS effectiveness is a full implementation of all applicable cost-effective NCS pathways in China.Our findings highlight the role of terrestrial carbon sequestration in offsetting energy-related CO_(2) emissions and put forward future needs in the context of carbon neutrality.Yao Huang Wenjuan Sun Zhangcai Qin Wen Zhang Yongqiang Yu Tingting Li Qing Zhang Guocheng Wang Lingfei Yu Yijie Wang Fan Ding Ping Zhang 2022National Science Review2022,9,8:4

13Schisandrol A protects AGEs-induced neuronal cells death by allosterically targeting ATP6V0d1 subunit of V-ATPase显示文摘Diabetes have been shown to cause progressive neuronal injury with pain and numbness via advanced glycation end-products(AGEs)-induced neuronal cell apoptosis;however, the valuable drug targets for diabetic neuropathy have been poorly reported so far. In this study, we discovered a natural small-molecule schisandrol A(SolA) with significant protective effect against AGEs-induced neuronal cell apoptosis. ATP6V0D1, a major subunit of vacuolar-type ATPase(V-ATPase) in lysosome was identified as a crucial cellular target of SolA. Moreover, SolA allosterically mediated ATP6V0D1 conformation via targeting a unique cysteine 335 residue to activate V-ATPase-dependent lysosomal acidification.Interestingly, SolA-induced lysosome pH downregulation resulted in a mitochondrial-lysosomal crosstalk by selectively promoting mitochondrial BH3-only protein BIM degradation, thereby preserving mitochondrial homeostasis and neuronal cells survival. Collectively, our findings reveal ATP6V0D1 is a valuable pharmacological target for diabetes-associated neuronal injury via controlling lysosomal acidification, and also provide the first small-molecule template allosterically activating V-ATPase for preventing diabetic neuropathy.Xiaoqing Zhou Shaoyang Zhao Tingting Liu Lu Yao Meimei Zhao Xiaoming Ye Xiaowen Zhang Qiang Guo Pengfei Tu Kewu Zeng 2022Acta Pharmaceutica Sinica B2022,12,10:3

15Simulated photo-degradation of dissolved organic matter in lakes revealed by three-dimensional excitation-emission matrix with regional integration and parallel factor analysis显示文摘Simulated photo-degradation of fluorescent dissolved organic matter(FDOM) in Lake Baihua(BH) and Lake Hongfeng(HF) was investigated with three-dimensional excitationemission matrix(3 DEEM) fluorescence combined with the fluorescence regional integration(FRI),parallel factor(PARAFAC) analysis,and multi-order kinetic models.In the FRI analysis,fulvic-like and humic-like materials were the main constituents for both BH-FDOM and HF-FDOM.Four individual components were identified by use of PARAFAC analysis as humic-like components(C1),fulvic-like components(C2),protein-like components(C3) and unidentified components(C4).The maximum 3 DEEM fluorescence intensity of PARAFAC components C1-C3 decreased by about 60%,70% and 90%,respectively after photo-degradation.The multi-order kinetic model was acceptable to represent the photo-degradation of FDOM with correlation coefficient(Radj2)(0.963-0.998).The photo-degradation rate constants(kn) showed differences of three orders of magnitude,from 1.09 × 10-6 to 4.02 × 10-4 min-1,and half-life of multi-order model(T1/2n)ranged from 5.26 to 64.01 min.The decreased values of fluorescence index(FI) and biogenic index(BI),the fact that of percent fluorescence response parameter of Region I(PⅠ,n) showed the greatest change ratio,followed by percent fluorescence response parameter of Region II(PⅡ,n,while the largest decrease ratio was found for C3 components,and the lowest T1/2n was observed for C3,indicated preferential degradation of protein-like materials/components derived from biological sources during photodegradation.This research on the degradation of FDOM by 3 DEEM/FRI-PARAFAC would be beneficial to understanding the photo-degradation of FD OM in natural environments and accurately predicting the environmental behaviors of contaminants in the presence of FDOM.Jin Zhang Fanhao Song Tingting Li Kefu Xie Huiying Yao Baoshan Xing Zhongyu Li Yingchen Bai 2020Journal of Environmental Sciences2020,32,4:3
16Rhubarb-based Chinese herbal formulae for hepatic encephalopa-thy:a systematic review and Meta-analysis显示文摘OBJECTIVE: To evaluate the effectiveness and safety of rhubarb-based Chinese herbal formulae(RCHF), which are widely used to treat hepatic encephalopathy(HE) in China.METHODS: Nine online databases were searched from inception to November 22, 2016. Eligible studies were randomized controlled trials of Traditional Chinese Medicine(TCM) treatment for adult patients(≥ 18 years old) with HE. Outcomes such as mortality rate, clinical response rate, blood ammonia level, and alanine aminotransferase were evaluated between TCM group and control group.RESULTS: Thirty studies involving 2661 HE patients were analyzed. Most studies used RCHF treatment.Compared with conventional treatment as usual,lactulose, and vinegar, RCHF were associated with significant improvement in clinical response rate[risk ratio(RR) = 1.33, 95% confidence interval(CI) =1.25, 1.43, I2= 0%; RR = 1.26, 95% CI = 1.14, 1.38, I2=22%; and RR = 1.19, 95% CI = 1.06, 1.33, I2= 0%, respectively] and significant reductions in levels of blood ammonia and alanine aminotransferase. Only minor RCHF-associated adverse events, such as abdominal pain(0.3%), anal tenesmus(0.3%), and diarrhea(2.3%), were reported, and there were no significant differences in these events between the treatment group and the three types of control group.CONCLUSION: The findings suggest that RCHF may be an alternative treatment option for HE patients. More rigorous multicenter studies with larger samples and longer observational periods are needed to confirm these findings.Zhang Ning Zhou Shuangnan Xiao Xiaohe Wanq Zhen Bai Yunfeng He Tingting Zhou Chao Wang Yao Kun Zhou Wang Zhongxia Liu Bing Larry J.Prokop Matthew C.Hernandez Li Jun Gong Man 2017Journal of Traditional Chinese Medicine2017,37,6:3
17Identification, through transcriptome analysis, of transcription factors that regulate anthocyanin biosynthesis in different parts of red-fleshed apple 'May' fruit显示文摘Anthocyanins, a class of flavonoid compounds that provide pigmentation to plant organs, are beneficial components of the human diet and there is an interest in understanding the regulation of their formation in crop plants. The apple cultivar ‘May’ represents an excellent model for the study of anthocyanin metabolism due to the spatial color pattern of its flesh, which transitions sequentially from red to white to red again,from the outside to the inside of the apple fruit. To screen the transcription factors involved in the anthocyanin pathway, transcriptomes from differently colored sections of ‘May’ fruits were analyzed by RNA sequencing. Kyoto Encyclopedia of Genes and Genomes(KEGG) database was used to analyse the gene expression data. The results suggested differentially expressed genes(DEGs) that are related to phytohormones are involved in regulating anthocyanin biosynthesis. K-means clustering analysis revealed 167 common DEGs between different sections of fruit with the same expression pattern as candidates for regulating anthocyanin synthesis. Further analysis showed that nine of the 167 DEGs were annotated as transcription factors and quantitative real time PCR(qRT-PCR) confirmed that their expression was obviously higher in red regions of the fruit, consistent with their roles as hub genes that regulate anthocyanin synthesis. This study provides valuable results for future studies of anthocyanin synthesis in apple fruit.Hua Li Shiyao Duan Weilei Sun Sifan Wang Jie Zhang Tingting Song Ji Tian Yuncong Yao 2022Horticultural Plant Journal2022,8,1:2
18Integrated single-cell RNA sequencing analysis reveals distinct cellular and transcriptional modules associated with survival in lung cancer显示文摘Lung adenocarcinoma(LUAD)and squamous carcinoma(LUSC)are two major subtypes of non-small cell lung cancer with distinct pathologic features and treatment paradigms.The heterogeneity can be attributed to genetic,transcriptional,and epigenetic parameters.Here,we established a multi-omics atlas,integrating 52 single-cell RNA sequencing and 2342 public bulk RNA sequencing.We investigated their differences in genetic amplification,cellular compositions,and expression modules.We revealed that LUAD and LUSC contained amplifications occurring selectively in subclusters of AT2 and basal cells,and had distinct cellular composition modules associated with poor survival of lung cancer.Malignant and stage-specific gene analyses further uncovered critical transcription factors and genes in tumor progression.Moreover,we identified subclusters with proliferating and differentiating properties in AT2 and basal cells.Overexpression assays of ten genes,including sub-cluster markers AQP5 and KPNA2,further indicated their functional roles,providing potential targets for early diagnosis and treatment in lung cancer.Li Zhang Yiming Zhang Chengdi Wang Ying Yang Yinyun Ni Zhoufeng Wang Tingting Song Menglin Yao Zhiqiang Liu Ningning Chao Yongfeng Yang Jun Shao Zhidan Li Ran Zhou Li Chen Dan Zhang Yuancun Zhao Wei Liu Yupeng Li Ping He Jing-wen Lin Yuan Wang Kang Zhang Lu Chen Weimin Li 2022Signal Transduction and Targeted Therapy2022,7,2:2
19An Outbreak of the SARS-CoV-2 Omicron Variant BA.1—Zhuhai City,Guangdong Province,China,January 13,2022显示文摘On January 13,2022,Zhuhai CDC received a notification that a coronavirus disease 2019(COVID-19)case was found in the fever clinic in nearby Zhongshan City.Zhuhai CDC promptly carried out large-scale population screening in three nearby counties.A total of 4 COVID-19 cases were found in Nanping County.34 cases were screened from close contacts,and 2 cases were reported from close contacts in other cities of Guangdong Province.The 20 cases were sequenced by Guangdong CDC and identified as the variant of concern(VOC)/Omicron variant BA.1.Since January 14,Zhuhai has carried out 8 rounds of nucleic acid screening for COVID-19 in the county where the cases occurred.Four large-scale nucleic acid screening tests for COVID-19 were conducted across the city,and no new community cases were reported after January 15.Feng Ruan Xuebao Zhang Songjian Xiao Xihe Ni Xiling Yin Zhongwen Ye Guorong Chen Tingting Zhu Zeling Chen Gang Yao Long Chen Sichen Huang Huitao Huang Yi Zhou Heyan Wu Hui Huang Kejing Zhu Shanzi Huang Xiaoou Tang Min Kang Bosheng Li Wenhua Mei 2022China CDC weekly2022,4,30:2
20Large-scale multiferroic complex oxide epitaxy with magnetically switched polarization enabled by solution processing显示文摘Complex oxides with tunable structures have many fascinating properties,though high-quality complex oxide epitaxy with precisely controlled composition is still out of reach.Here we have successfully developed solution-based single-crystalline epitaxy for multiferroic(1-x)BiTi(1-y)/2FeyMg(1-y)/2O3–(x)CaTiO3(BTFM–CTO)solid solution in large area,confirming its ferroelectricity at the atomic scale with strong spontaneous polarization.Careful compositional tuning leads to a bulk magnetization of 0.07±0.035μB/Fe at room temperature,enabling magnetically induced polarization switching exhibiting a large magnetoelectric coefficient of 2.7–3.0×10^-7 s/m.This work demonstrates the great potential of solution processing in large-scale complex oxide epitaxy and establishes novel room-temperature magnetoelectric coupling in epitaxial BTFM–CTO film,making it possible to explore a much wider space of composition,phase,and structure that can be easily scaled up for industrial applications.Cong Liu Feng An Paria S.M.Gharavi Qinwen Lu Junkun Zha Chao Chen Liming Wang Xiaozhi Zhan Zedong Xu Yuan Zhang Ke Qu Junxiang Yao Yun Ou Zhiming Zhao Xiangli Zhong Dongwen Zhang Nagarajan Valanoor Lang Chen Tao Zhu Deyang Chen Xiaofang Zhai Peng Gao Tingting Jia Shuhong Xie Gaokuo Zhong Jiangyu Li 2020National Science Review2020,7,1:2
