| 1 | Hyperthermic intraperitoneal chemotherapy for gastric cancer with peritoneal metastasis:A multicenter propensity scorematched cohort study显示文摘Objective:Systemic chemotherapy has limited efficacy in the treatment of peritoneal metastasis(PM)in gastric cancer(GC).Hyperthermic intraperitoneal chemotherapy(HIPEC)combined with complete cytoreductive surgery(CRS)has shown promising outcomes but remains controversial.The present study aimed to evaluate the safety and efficacy of HIPEC without CRS in GC patients with PM.Methods:This retrospective propensity score-matched multicenter cohort study included GC patients with PM treated with either chemotherapy alone(Cx group)or with HIPEC combined with chemotherapy(HIPEC-Cx group)in four Chinese high-volume gastric medical centers between 2010 and 2017.The primary outcomes were median survival time(MST)and 3-year overall survival(OS).Propensity score matching was performed to compensate for controlling potential confounding effects and selection bias.Results:Of 663 eligible patients,498 were matched.The MST in the Cx and HIPEC-Cx groups was 10.8 and 15.9 months,respectively[hazard ratio(HR)=0.71,95%confidence interval(95%CI),0.58-0.88;P=0.002].The 3-year OS rate was 10.1%(95%CI,5.4%-14.8%)and 18.4%(95%CI,12.3%-24.5%)in the Cx and HIPEC-Cx groups,respectively(P=0.017).The complication rates were comparable.The time to first flatus and length of hospital stay for patients undergoing HIPEC combined with chemotherapy was longer than that of chemotherapy alone(4.6±2.4 d vs.2.7±1.8 d,P<0.001;14.2±5.8 d vs.11.4±7.7 d,P<0.001),respectively.The median follow-up period was 33.2 months.Conclusions:Compared with standard systemic chemotherapy,HIPEC combined with chemotherapy revealed a statistically significant survival benefit for GC patients with PM,without compromising patient safety. | Ziying Lei Jiahong Wang Zhi Li Baozhong Li Jiali Luo Xuejun Wang Jin Wang MingchenBa Hongsheng Tang Qingjun He Quanxing Liao Xiansheng Yang Tianpei Guan Han Liang Shuzhong Cui | 2020 | Chinese Journal of Cancer Research2020，32，6： | 11 |
| 2 | Chemical fingerprint analysis of Gentianae Radix et Rhizoma by high-performance liquid chromatography显示文摘Gentianae Radix et Rhizoma(also called 'Longdan' in Chinese)is commonly used for eliminating damp-heat and quenching the fire of liver and gall bladder in traditional Chinese medicine.In this study,a novel and reliable method using high-performance liquid chromatography(HPLC)was developed both for quantitative analysis of four bioactive compounds(loganic acid,swertiamarin,gentiopicroside and sweroside)and chemical fingerprint analysis of 'Longdan'.In quantitative analysis,four compounds showed good regressions(R^(2)>40.9987)within the test ranges and the recovery of the method was in the range 97.61-102.49%.In fingerprint analysis,ten characteristic peaks were selected to evaluate the similarities of the crude drugs,and the HPLC chromatograms of twenty samples from different regions of China showed similar patterns.The results demonstrated that the combination of the quantitative and chromatographic fingerprint analyses offered an efficient way to evaluate the quality consistency of Gentianae Radix et Rhizoma. | Baozhong Duan Jianyong Hu Linfang Huang Xianying Yang Fuying Chen | 2012 | Acta Pharmaceutica Sinica B2012，2，1： | 8 |
| 3 | Interface electron collaborative migration of Co–Co3O4/carbon dots:Boosting the hydrolytic dehydrogenation of ammonia borane显示文摘Ammonia borane(AB)is an excellent candidate for the chemical storage of hydrogen.However,its practical utilization for hydrogen production is hindered by the need for expensive noble-metal-based catalysts.Herein,we report Co-Co3O4 nanoparticles(NPs)facilely deposited on carbon dots(CDs)as a highly efficient,robust,and noble-metal-free catalyst for the hydrolysis of AB.The incorporation of the multiinterfaces between Co,Co3O4 NPs,and CDs endows this hybrid material with excellent catalytic activity(rB=6816 mLH2 min^-1 gCo^-1)exceeding that of previous non-noble-metal NP systems and even that of some noble-metal NP systems.A further mechanistic study suggests that these interfacial interactions can affect the electronic structures of interfacial atoms and provide abundant adsorption sites for AB and water molecules,resulting in a low energy barrier for the activation of reactive molecules and thus substantial improvement of the catalytic rate. | Han Wu Min Wu Boyang Wang Xue Yong Yushan Liu Baojun Li Baozhong Liu Siyu Lu | 2020 | Journal of Energy Chemistry2020，29，9： | 7 |
| 4 | Mitochondrial dysfunction activates the AMPK signaling and autophagy to promote cell survival显示文摘Autophagy is a cellular self-eating process essential for stress response and maintainingtissue homeostasis by lysosomal degradation of unwanted or damaged proteins and organelles.Here, we show that cells with defective mitochondria induce autophagy to promotecell survival through activating the AMPK pathway. Loss of mitochondrial complex III proteincytochrome b activates the AMPK signaling and induced autophagy. Inhibiting mitochondria energeticsby mitochondria-targeted agents activates the AMPK signaling and induced autophagy.Genetic inhibition of AMPK inhibits autophagy induction in cells with defective mitochondria,while genetic inhibition of autophagy has no effect on AMPK activation. Mitochondria dysfunctionhas no effect of DNA repair of UV-induced DNA damage. However, mitochondria dysfunctionsensitizes cells to apoptosis induced by UV radiation. Genetic inhibition of autophagy orAMPK sensitized cells to apoptosis in cells with defective mitochondria. Our results demonstratethat AMPK and autophagy senses mitochondria dysfunction and serves as a mechanismfor survival. Our findings may provide new insights into the interplay between mitochondriafunction and autophagy process in maintaining tissue homeostasis, and suggest that this interactionmay play important roles in diseases such as cancer and neurodegeneration. | Baozhong Zhao Lei Qiang Joy Joseph Balaraman Kalyanaraman Benoit Viollet Yu-Ying He | 2016 | Genes & Diseases2016，3，1： | 6 |
| 5 | Application and comparison of winter wheat canopy resistance estimation models based on the scaling-up of leaf stomatal conductance显示文摘Canopy resistance estimation model based on the scaling-up leaf stomatal resistance is the focus of evapotrantion research, as there is a need to select the proper scaling-up model for winter wheat in typical areas of North China. Two years of field experimental data are used for the Leuning-Ball and Jarvis stomatal model calibration and validation, canopy resistance estimation models are established based on Leuning-Ball and Jarvis stomatal models, their application effects are compared and verified. Results show that daily variation of stomatal resistance of winter wheat is higher than that of canopy resistance, and there exists scale differences between leaf and canopy scale; Leuning-Ball stomatal model can be better explicated by the response of stomatal conductance towards environmental factors; Leuning-Ball canopy resistance estimation models turn out to be an effective canopy resistance simulation, and thus can be applied to research on the scaling-up of vapor transmission resistance of winter wheat in typical areas of North China. | WEI Zheng LIU Yu XU Di CAI JiaBing ZHANG BaoZhong | 2013 | Chinese Science Bulletin2013，58，23： | 6 |
| 6 | Structural effects of three-dimensional angle-interlock woven composite undergoing bending cyclic loading显示文摘This paper reports the structural effects of three-dimensional(3-D)angle-interlock woven composite(3DAWC)undergoing three-point bending cyclic loading from experimental and finite element analysis(FEA)approaches.In experiment,the fatigue tests were conducted to measure the bending deflection and to observe the damage morphologies.By the FEA approach,a micro-structural unit-cell model of the 3DAWC was established at the yarn level to simulate the fatigue damage.The stress degradation at the loading condition of constant deformation amplitude was calculated to show the degradation of mechanical properties.In addition,the stress distribution,fatigue damage evolution and critical damage regions were also obtained to qualitatively reveal the structural effects and damage mechanisms of the 3DAWC subjected to three-point bending cyclic loading. | JIN LiMin YAO Yao YU YiMin ROTICH Gideon SUN BaoZhong GU BoHong | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，3： | 5 |
| 7 | A Comparative Analysis of the Chloroplast Genomes of Four Salvia Medicinal Plants显示文摘Herbgenomics is an emerging field of traditional Chinese medicine(TCM)research and development.By combining TCM research with genomics,herbgenomics can help to establish the scientific validity of TCM and bring it into wider usage within the field of medicine.Salvia Linn.(S.Linn.)is a large genus of Labiatae that includes important medicinal plants.In this herbgenomics study,the complete chloroplast(cp)genomes of two Salvia spp.—namely,S.przewalskii and S.bulleyana,which are used as a surrogate for S.miltiorrhiza—were sequenced and compared with those of two other reported Salvia spp.—namely,S.miltiorrhiza and S.japonica.The genome organization,gene number,type,and repeat sequences were compared.The annotation results showed that both Salvia plants contain 114 unique genes,including 80 protein-coding,30 transfer RNA(tRNA),and four ribosomal RNA(rRNA)genes.Repeat sequence analysis revealed 21 forward and 22 palindromic sequences in both Salvia cp genomes,and 17 and 21 tandem repeats in S.przewalskii and S.bulleyana,respectively.A synteny comparison of the Salvia spp.cp genomes showed a high degree of sequence similarity in the coding regions and a relatively high divergence of the intergenic spacers.Pairwise alignment and single-nucleotide polymorphism(SNP)analyses found some candidate fragments to identify Salvia spp.,such as the intergenic region of the trnV–ndhC,trnQ–rps16,atpI–atpH,psbA–ycf3,ycf1,rpoC2,ndhF,matK,rpoB,rpoA,and accD genes.All of the results—including the repeat sequences and SNP sites,the inverted repeat(IR)region border,and the phylogenetic analysis—showed that S.przewalskii and S.bulleyana are extremely similar from a genetic standpoint.The cp genome sequences of the two Salvia spp.reported here will pave the way for breeding,species identification,phylogenetic evolution,and cp genetic engineering studies of Salvia medicinal plants. | Conglian Liang Lei Wang Juan Lei Baozhong Duan Weisi Ma Shuiming Xiao Haijun Qi Zhen Wang Yaoqi Liu Xiaofeng Shen Shuai Guo Haoyu Hu Jiang Xu Shilin Chen | 2019 | Engineering2019，5，5： | 5 |
| 8 | Phase structure and hydrogen storage properties of LaMg_(3.70)Ni_(1.18) alloy显示文摘The phase structure and hydrogen storage properties of LaMg 3.70 Ni 1.18 alloy were investigated. The LaMg 3.70 Ni 1.18 alloy consists of main LaMg 2 Ni phase, minor La 2 Mg 17 and LaMg 3 phases. The alloy can be activated in the first hydriding/dehydriding process, and initial LaMg 2 Ni, La 2 Mg 17 , and LaMg 3 phases transfer to LaH 2.34 , Mg, and Mg 2 Ni phases after activation. The reversible hydrogen storage capacity of the LaMg 3.70 Ni 1.18 alloy is 2.47 wt.% at 558 K, which is higher than that of the LaMg 2 Ni alloy. The pressure-composition-temperature (PCT) curves display two hydriding plateaus, corresponding to the formation of MgH 2 and Mg 2 NiH 4 . However, only one dehydriding plateau is observed, owing to the synergetic effect of hydrogen desorption between MgH 2 and Mg 2 NiH 4 . The uptake time for hydrogen content to reach 99% of saturated state is less than 250 s, and 90% hydrogen can be released in 1200 s in the experimental conditions, showing fast kinetics in hydriding and dehydriding. The activation energies of the LaMg 3.70 Ni 1.18 alloy are -51.5 ± 1.1 kJ/mol and -57.0 ± 0.6 kJ/mol for hydriding and dehydriding, respectively. The hydriding/dehydriding kinetics of the LaMg 3.70 Ni 1.18 alloy is better than that of the Mg 2 Ni alloy, owing to the lower activation energy values. | LI Jinhua LIU Baozhong HAN Shumin HU Lin ZHAO Xin WANG Mingzhi | 2011 | Rare Metals2011，30，5： | 4 |
| 9 | Catalytic Performance of MFI/MFI Core-Shell Zeolites in Benzene Methylation显示文摘Thanks to its 10-membered-ring structure with a three-dimensional uniform pore system and acid distribution, ZSM-5 zeolite is a key catalytic material for benzene methylation with methanol. After epitaxial inter-growth of a dense layer of shell consisting of nano-particles on the conventional ZSM-5 crystal surface, the MFI/MFI core-shell zeolite not only has much more active surface area, but also can enrich the diffusion and reaction pore system at the same time, which can significantly improve its catalytic performance. In contrast to the performance of conventional ZSM-5 catalyst, an indepth investigation on the reaction parameters of benzene methylation over the core-shell structured zeolite is of great significance. | Zhang Baozhong Liu Xiaopeng | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，4： | 4 |
| 10 | Ice core dust particulate by XPS-SEM/EDAX——Impact of dust particulate on SO_4^(2-) record in ice cores显示文摘The ice core dust particulate sampled from Mt. Xixabangma has been analyzed by means of X-ray photoelectron spectrometer (XPS) and scanning electron microscope with energy dispersion X-ray analysis (SEM/EDAX). The results show that the contents of SO42- and SO32- in the surface layer of the dust are significantly higher than those in the subsurface layer (with the exception of organic sulfide). This difference indicates that the surface SOx has been captured and then chemically converted by the atmospheric dust particulate before its deposition with snow, which is obviously different from those inner layer sulfates and sulfites contained by dust itself. In addition, it has been determined by SEM/EDAX that the dust contains relatively high concentrations of transition metal elements such as Fe and Ti oxides which could function as photocatalysts to the conversion of SOx adhered on the surface of the dust, and consequently accelerate the deposition of SOx to snow.

| 11 | Small Angle X-ray Scattering Study of Precipitation Kinetics in Al-Zn-Mg-Cu Alloys显示文摘The evolution of microstructure parameters (precipitate size and volume fraction) for two types of Al-Zn-Mg-Cu alloys (7075 and 7055) during aging has been studied by synchrotron-radiation small angle X-ray scattering (SAXS).The results show that the precipitates are only a few nanometers for both alloys ageing even at higher temperature of 160℃ for 72 h (4.44 and 5.82 nm, respectively). The maximum of the precipitate volume fraction increases with in creasing Zn content and is about 0.023~0.028 and 0.052~0.054, respectively. The coarsening of precipitate is consistent with LSW (Lifshitz-Slyozov-Wagner) model even at the initial stage where volume fraction is still varying.The activation energy of coarsening regime has been determined to be about 1.22±0.02 eV and 1.25±0.02 eV for alloys 7075 and 7055, respectively. | Zhiwei DU Tietao ZHOU Peiying LIU Huanxi LI Baozhong DONG Changqi CHEN | 2005 | Journal of Materials Science & Technology2005，21，4： | 3 |
| 12 | Detection of Porcine Epidemic Diarrhea Virus in Guangxi Province from 2011 to 2014 and Sequence Analysis of Its M Gene显示文摘Detection of pigs epidemic diarrhea virus( PEDV) was conducted on 331 piglets diarrhea fecal samples collected in Nanning,Yulin and other 12 areas of Guangxi Province from January of 2011 to April of 2014 by the method of reverse transcription-polymerase chain reaction( RT-PCR). The results showed that the positive samples of PEDV were 210 and the positive rate was 63. 44%. The clone and sequencing of M gene was carried out on 25 positive samples. PEDV reference strains were selected from Gene Bank to conduct the sequence homology alignment analysis and the phylogenetic tree of M gene. The M gene homology and amino acid sequence identity between 25 isolated strains and 51 reference strains were 96. 0%- 99. 6% and 94. 3%- 99. 6%,respectively. The genetic variation analysis of M gene showed that the genetic relationship of PEDV prevalent strains in Guangxi Province from 2013 to 2014 was close to that of the prevalent strains in Beijing,Anhui,Wuhan,Hebei and Guangdong from 2010 to 2013,and which were far from that of the Chinese early isolates CH / S( Gen Bank number: JN547228),vaccine strain CV777( Gen Bank number: AF353511) and Attenuated DR13( Gen Bank number: JQ023162). Indicating that the PEDV strains prevalent in Guangxi in recent years showed significant variation with the early isolates. | Lu Bingxia Qin Yibin He Ying Li Yingying Liang Jiaxing Li Keyu Li Bin Su Qianlian Zhou Yingning Jiang Dongfu Lu Jingzhuan Bi Bingfen Liang Baozhong Duan Qunpeng Zhao Wu | 2016 | Animal Husbandry and Feed Science2016，8，1： | 3 |

| 16 | Co-CoO_x supported onto TiO_(2) coated with carbon as a catalyst for efficient and stable hydrogen generation from ammonia borane显示文摘Ammonia borane(AB) can be catalytically hydrolyzed to provide hydrogen at room temperature due to its high potentaial for hydrogen storage. Non-precious metal heterogeneous catalysts have broad application in the field of energy catalysis. In this article, catalysts precursor is obtained from Co-Ti-resorcinol-formaldehyde resin by sol–gel method. Co/TiO_(2)@N-C(CTC) catalyst is prepared by calcining the precursor under high temperature conditions in nitrogen atmosphere. Co-CoO_x/TiO_(2)@N-C(COTC) is generated by the controllable oxidation reaction of CTC. The catalyst can effectively promote the release of hydrogen during the hydrolytic dehydrogenation of AB. High hydrogen generation at a specific rate of 5905 m L min^(-1) g_(Co)^(-1) is achieved at room temperature. The catalyst retains its 85% initial catalytic activity even for its fifth time use in AB hydrolysis. The synergistic effect among Co, Co_(3)O_(4) and TiO_(2) promotes the rate limiting step with dissociation and activation of water molecules by reducing its activation energy. The applied method in this study promotes the development of non-precious metals in catalysis for utilization in clean energy sources. | Guang Yang Shuyan Guan Sehrish Mehdi Yanping Fan Baozhong Liu Baojun Li | 2021 | Green Energy & Environment2021，6，2： | 2 |

| 19 | Carbon dots-confined CoP-CoO nanoheterostructure with strong interfacial synergy triggered the robust hydrogen evolution from ammonia borane显示文摘Ammonia borane(NH_(3)BH_(3),AB) is promising for chemical hydrogen sto rage;however,current systems for rapid hydrogen production are limited by the expensive noble metal catalysts required for AB hydrolysis.Here we report the design and synthesis of a highly efficient and robust non-noble-metal catalyst for the hydrolysis of AB at 298 K(TOF=89.56 molH_(2) min^(-1) molCo^(-1)).Experiments and density functional theory calculations were performed to explore the catalyst’s hybrid nanoparticle heterostructure and its catalytic mechanism.The catalyst comprised nitrogen-doped carbon dots confining CoO and CoP,and exhibited strong interface-induced synergistic catalysis for AB hydrolysis that effectively decreased the energy barriers for the dissociation of both AB and water molecules.The co-doping of N and P introduced numerous defects,and further regulated the reactivity of the carbon layers.The heterogeneous interface design technique presented here provides a new strategy for developing efficient and inexpensive non-noblemetal catalysts that may be applicable in other fields related to energy catalysis. | Han Wu Yaojia Cheng Boyang Wang Yao Wang Min Wu Weidong Li Baozhong Liu Siyu Lu | 2021 | Journal of Energy Chemistry2021，30，6： | 2 |
| 20 | Comprehensive utilization of complex rubidium ore resources:Mineral dissociation and selective leaching of rubidium and potassium显示文摘Currently,the process of extracting rubidium from ores has attracted a great deal of attention due to the increasing application of rubidium in high-technology field.A novel process for the comprehensive utilization of rubidium ore resources is proposed in this paper.The process consists mainly of mineral dissociation,selective leaching,and desilication.The results showed that the stable silicon–oxygen tetrahedral structure of the rubidium ore was completely disrupted by thermal activation and the mineral was completely dissociated,which was conducive to subsequent selective leaching.Under the optimal conditions,extractions of 98.67% Rb and 96.23%K were obtained by leaching the rubidium ore.Moreover,the addition of a certain amount of activated Al(OH)_(3) during leaching can effectively inhibit the leaching of silicon.In the meantime,the leach residue was sodalite,which was successfully synthesized to zeolite A by hydrothermal conversion.The proposed process provided a feasible strategy for the green extraction of rubidium and the sustainable utilization of various resources. | Quankuang Zhang Baozhong Ma Chengyan Wang Yongqiang Chen Wenjuan Zhang | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，5： | 2 |
