| 1 | Pretreatment with scutellaria baicalensis stem-leaf total flavonoid prevents cerebral ischemia-reperfusion injury显示文摘Pretreatment with scutellaria baicalensis stem-leaf total flavonoid has protective effects against ischemia and attenuates myocardial ischemia-reperfusion injury.In this study,rats were given scutellaria baicalensis stem-leaf total flavonoid intragastrically at 50,100,and 200 mg/kg per day for7 days before focal cerebral ischemia-reperfusion injury models were established using the suture method.We then determined the protective effects of scutellaria baicalensis stem-leaf tota flavonoid pretreatment on focal cerebral ischemia-reperfusion injury.Results showed that neurological deficit scores increased,infarct volumes enlarged,apoptosis increased and Bcl-2 and Bax protein expression were upregulated at 24 hours after reperfusion.Pretreatment with scutellaria baicalensis stem-leaf total flavonoid at any dose lowered the neurological deficit scores reduced the infarct volume,prevented apoptosis in hippocampal cells,attenuated neuronal and blood-brain barrier damage and upregulated Bcl-2 protein expression but inhibited Bax protein expression.Doses of 100 and 200 mg/kg were the most efficacious.Our findings indicate that pretreatment with scutellaria baicalensis stem-leaf total flavonoid at 100 and 200 mg/kg can improve the neurological functions and have preventive and protective roles after focal cerebra ischemia-reperfusion injury. | Shumin Zhao Wei Kong Shufeng Zhang Meng Chen Xiaoying Zheng Xiangyu Kong | 2013 | Neural Regeneration Research2013,8,34: | 11 |
| 2 | Floor heave characteristics and control technology of the roadway driven in deep inclined-strata显示文摘Based on in-mine instrumentation and theoretical analysis of the unsymmetrical large-deformation that occurred in the roadway after excavation,Differential Floor Heave(DFH)was found to be the main reason for roadway failure.It needs to be pointed out that the specific roadway was driven in inclined rock strata.In addition,the factors that contribute to the occurrence of DFH are discussed in detail.It is believed that DFH is triggered by the unsymmetrical stress distribution in the floor and the different rock types encountered near the two floor corners.Hence,DFH control should be focused on the left floor corner where shearing failure occurs initially and the left floor surface where tensile failure is more severe.The proposed DFH control strategies include unsymmetrical grouting for the whole roadway,re-design of the roof and ribs support,reinforcement of the weak zones,and release of the concentrated stress in the earlier stage.Meanwhile,it is recommended that in the later stage,both bolts and cable bolts with higher strength and the backfilling technique using the coal measure rocks and concrete should be employed in the reversed-arch floor.The field instrumentation results,after using the proposed control strategies,indicate that large deformation in a DFH roadway has been successfully controlled. | Wang Meng Guo Guanlong Wang Xiangyu Guo Yu Dao Vietdoan | 2015 | International Journal of Mining Science and Technology2015,25,2: | 7 |
| 3 | Pretreatment with scutellaria baicalensis stem-leaf total flavonoid protects against cerebral ischemia/reperfusion injury in hippocampal neurons显示文摘Previous experimental studies have shown that cerebral infarction can be effectively reduced following treatment with scutellaria baicalensis stem-leaf total flavonoid(SSTF). However, the mechanism of action of SSTF as a preventive drug to treat cerebral infarction remains unclear. In this study, Sprague-Dawley rats were pretreated with 50, 100, 200 mg/kg SSTF via intragastric administration for 1 week prior to the establishment of focal cerebral ischemia/reperfusion injury. The results showed that pretreatment with SSTF effectively improved neurological function, reduced brain water content and the permeability of blood vessels, ameliorated ischemia-induced morphology changes in hippocampal microvessels, down-regulated Fas and Fas L protein expression, elevated the activity of superoxide dismutase and glutathione peroxidase, and decreased malondialdehyde content. In contrast to low-dose SSTF pretreatment, the above changes were most obvious after pretreatment with moderate- and high-doses of SSTF. Experimental findings indicate that SSTF pretreatment can exert protective effects on the brain against cerebral ischemia/reperfusion injury. The underlying mechanisms may involve reducing brain water content, increasing microvascular recanalization, inhibiting the apoptosis of hippocampal neurons, and attenuating free radical damage. | Xiangyu Kong Wei Kong Guangxin Miao Shumin Zhao Meng Chen Xiaoying Zheng Jiangtao Bai | 2014 | Neural Regeneration Research2014,9,23: | 7 |
| 4 | Gut microbiome alterations and its link to corticosteroid resistance in immune thrombocytopenia显示文摘Quantitative metagenomic studies have linked the gut microbiota to autoimmune disorders.Here,we performed deep shotgun metagenomic sequencing of fecal samples from 99 immune thrombocytopenia(ITP)patients and 52 healthy controls.Dysbiosis in the gut microbiome of ITP was detected phylogenetically and functionally,and classifier based on species markers distinguished individuals with ITP from healthy controls.In particular,the abundance of Ruminococcus gnavus,Bifidobacterium longum and Akkermansia muciniphila was markedly increased in treatment-na?ve ITP patients,and the alterations of microbial species were correlated with clinical indices.Functionally,the secondary bile acid biosynthesis and flagellar assembly were depleted in the gut microbiota of ITP,which may contribute to the onset of ITP by affecting the immune system.Furthermore,we found that corticosteroid treatment affected the gut microbiome of ITP.Compared with corticosteroid-sensitive ITP patients,we identified that the corticosteroid-resistant ITP patients displayed a distinct gut microbiome,which was different from that of the treatment-na?ve ITP patients.Together,we provided support for the critical role of gut microbiota in the development of ITP and established a foundation for further research characterizing gut microbiota in relation to corticosteroid resistance of ITP. | Yanan Wang Fengqi Liu Gaochao Zhang Yan Su Xueyan Sun Qi Chen Chencong Wang Haixia Fu Yun He Xiaolu Zhu Xiao Liu Meng Lv Xiangyu Zhao Xiaosu Zhao Yueying Li Qianfei Wang Xiaojun Huang Xiaohui Zhang | 2021 | Science China(Life Sciences)2021,64,5: | 6 |
| 5 | Efficient and stable tin-based perovskite solar cells by introducing π-conjugated Lewis base显示文摘Tin-based perovskite solar cells(TPSCs)as the most promising candidate for lead-free PSCs have incurred extensive researches all over the world.However,the crystallization process of tin-based perovskite is too fast during the solution-deposited process,resulting in abundant pinholes and poor homogeneity that cause serious charge recombination in perovskite layer.Here,we employed theπ-conjugated Lewis base molecules with high electron density to systematically control the crystallization rate of FASnI3 perovskite by forming stable intermediate phase with the Sn-I frameworks,leading to a compact and uniform perovskite film with large increase in the carrier lifetime.Meanwhile,the introduction of theπ-conjugated systems also retards the permeation of moisture into perovskite crystal,which significantly suppresses the film degradation in air.These benefits contributed to a stabilizing power conversion efficiency(PCE)of 10.1%for the TPSCs and maintained over 90%of its initial PCE after 1000-h light soaking in air.Also,a steady-state efficiency of 9.2%was certified at the accredited test center. | Tianhao Wu Xiao Liu Xin He Yanbo Wang Xiangyue Meng Takeshi Noda Xudong Yang Liyuan Han | 2020 | Science China Chemistry2020,63,1: | 6 |
| 6 | Optimal configuration for photovoltaic storage system capacity in 5G base station microgrids显示文摘Base station operators deploy a large number of distributed photovoltaics to solve the problems of high energy consumption and high electricity costs of 5G base stations.In this study,the idle space of the base station’s energy storage is used to stabilize the photovoltaic output,and a photovoltaic storage system microgrid of a 5G base station is constructed.Aiming at the capacity planning problem of photovoltaic storage systems,a two-layer optimal configuration method is proposed.The inner layer optimization considers the energy sharing among the base station microgrids,combines the communication characteristics of the 5G base station and the backup power demand of the energy storage battery,and determines an economic scheduling strategy for each photovoltaic storage system with the goal of minimizing the daily operation cost of the base station microgrid.The outer model aims to minimize the annual average comprehensive revenue of the 5G base station microgrid,while considering peak clipping and valley filling,to optimize the photovoltaic storage system capacity.The CPLEX solver and a genetic algorithm were used to solve the two-layer models.Considering the construction of the 5G base station in a certain area as an example,the results showed that the proposed model can not only reduce the cost of the 5G base station operators,but also reduce the peak load of the power grid and promote the local digestion of photovoltaic power. | Xiufan Ma Ying Duan Xiangyu Meng Qiuping Zhu Zhi Wang Sijia Zhu | 2021 | Global Energy Interconnection2021,4,5: | 5 |
| 7 | Coupling of Hierarchical Al_(2)O_(3)/TiO_(2) Nanofibers into 3D Photothermal Aerogels Toward Simultaneous Water Evaporation and Purification显示文摘Serious freshwater shortage and environmental pollution boost the rapid development of solar-driven water production.Although improved evaporation rate has achieved in recent years,undesirable impurity(e.g.,pollutant components)can also be inevitably evaporated and collected as impurity in produced freshwater.This work reports new ultra-light three-dimensional(3D)aerogels assembled by hierarchical Al_(2)O_(3)/TiO_(2) nanofibers and reduced graphene oxide(RGO)for excit-ing synchronized solar-driven evaporation and water purification.Hydrophilic Al_(2)O_(3)/TiO_(2) fibrous channels linked up the graphene hot-spots and water body for sufficient water supply and bulk water insulation.Meanwhile,featured with thermal insulation effect,the Al_(2)O_(3)/TiO_(2) nanofibers effectively locked the converted heat with less energy loss from sunlight.The introducing of Al_(2)O_(3)/TiO_(2) nanofibers into RGO aerogel led to the effective interfacial evaporation for a more rapid water evaporation rate(2.19 kg·m−2·h−1,normalized to evaporation area including both top and side surface),which was 36%higher than that of pristine RGO aerogel.Moreover,simultaneous with the strong steam generation,Al_(2)O_(3)/TiO_(2) nanofibers in situ removed the pollutants within steam by photodegradation,achieving polluted wastewater purification with high con-taminant removal ratio of 91.3%.Our work on coupling Al_(2)O_(3)/TiO_(2) nanofibers into photothermal aerogel provides attractive solutions for the challenges of clean water scarcity and serious environmental pollution. | Xiangyu Meng Wanlin Xu Zhihui Li Jianhui Yang Jingwu Zhao Xixi Zou Yueming Sun Yunqian Dai | 2020 | Advanced Fiber Materials2020,2,2: | 4 |
| 8 | Design and immunogenicity assessment of HIV-1 virus-like particles as a candidate vaccine显示文摘The rapid growth of the global HIV/AIDS epidemic makes it a high priority to develop an effective vaccine.Since a live attenuated or inactivated HIV vaccine is not likely to be approved for clinical application due to safety concerns,HIV virus like particles(VLPs) offer an attractive alternative because they are considered safer since they lack viral genome.We got a stable eukaryotic cell line by G418 resistance selection,engineered to express the HIV-1 structure protein Gag and Env efficiently and stably.We confirmed the presence of Gag and Env proteins in the cell culture supernatant and that they could self-assemble into VLPs.These VLPs were found to be able to elicit specific humoral and cellular immune response after immunization without any adjuvant. | ZHANG XiZhen WANG XiaoDan ZHAO DongHai MENG XiangYu ZHAO XingHong YU XiangHui KONG Wei | 2011 | Science China(Life Sciences)2011,54,11: | 4 |
| 9 | Effect of electronic stimulation at Neiguan(PC 6) acupoint on gene expression of adenosine triphosphate-sensitive potassium channel and protein kinases in rats with myocardial ischemia显示文摘OBJECTIVE:To investigate the effects of electronic stimulation at acupoints Neiguan(PC 6) and Lieque(LU 7) on the gene expression of the adenosine triphosphate(ATP)-Sensitive potassium channel(KATP:Kir6.1,Kir6.2,SUR2 A,and SUR2B) and protein kinases(PKA,PKG,and PKCβ2) in myocardial cells of rats with myocardial ischemia(Ml) induced by isoproterenol(ISO).METHODS:Rats were randomly divided into a control,model,Neiguan(PC 6),Lieque(LU 7),and non-acupoint groups.The Ml model was established by injecting rats with ISO.Electro-acupuncture treatment was given to the acupuncture groups,once a day for 7 days.Gene expression was analyzed with real-time PCR.RESULTS:The gene expression of KATP and protein kinases in the model group was higher than those in the control group(P < 0.05).After acupuncture treatment,the KATP and protein kinase expression levels were significantly lower in the Neiguan(PC 6)and Lieque(LU 7) groups compared with the model group[P < 0.05).The Neiguan(PC 6) group lowered these levels significantly more than that of the Lieque(LU 7) group(P < 0.05).No significant differences were observed between the model and non-acupoint groups(P > 0.05).CONCLUSION:Our findings suggest that electronic needling of Neiguan(PC 6) can both reduce the gene expression of KATP and protein kinases in rats with ISO-induced Ml. | Wang Wei Li Jiquan Meng Xiangyu Chen Yiguo | 2015 | Journal of Traditional Chinese Medicine2015,35,5: | 4 |
| 10 | Optimal configuration of 5G base station energy storage considering sleep mechanism显示文摘The high-energy consumption and high construction density of 5G base stations have greatly increased the demand for backup energy storage batteries.To maximize overall benefits for the investors and operators of base station energy storage,we proposed a bi-level optimization model for the operation of the energy storage,and the planning of 5G base stations considering the sleep mechanism.A multi-base station cooperative system composed of 5G acer stations was considered as the research object,and the outer goal was to maximize the net profit over the complete life cycle of the energy storage.Furthermore,the power and capacity of the energy storage configuration were optimized.The inner goal included the sleep mechanism of the base station,and the optimization of the energy storage charging and discharging strategy,for minimizing the daily electricity expenditure of the 5G base station system.Additionally,genetic algorithm and mixed integer programming were used to solve the bi-level optimization model,analyze the numerical example test comparison of the three types of batteries and the net income of the configuration,and finally verify the validity of the model.Furthermore,the sleep mechanism,the charging and discharging strategy for energy consumption,and the economic benefits for the operators were investigated to provide reference for the 5G base station energy storage configuration. | Xiufan Ma Qiuping Zhu Ying Duan Xiangyu Meng Zhi Wang | 2022 | Global Energy Interconnection2022,5,1: | 4 |
| 11 | Preparation and Application of Light-weight Raw Materials Using Natural Forsterite显示文摘In order to develop new basic light-weight refractory raw materials,natural forsterite(<0.045 mm)and magnesite(<0.045 mm)were batched according to the chemical composition of forsterite(2MgO·SiO_(2)),wet milled,semi-dry molded and calcined at different temperatures.Then cylinder samples with diameter of 36 mm were prepared.The effects of the wet milling jar rotation speed,the calcination temperature and the anthracite addition on the properties of the samples were researched.The results show that:when the calcination temperature exceeds 1300℃,all the mineral phases have converted to the desired phases;with the increase of the rotation speed and the calcination temperature,the bulk density of the samples increases,the apparent porosity decreases and the compressive strength improves.By comprehensive consideration,400 r·min^(-1) and 1450℃ are taken as the optimal scheme.High addition of anthracite makes the samples light,so series of light-weight raw materials with uniformly distributed micro-pores can be gained.The light-weight raw materials achieved were used for insulation refractory castables,obtaining good application. | MENG Chao MENG Qingxin LI Xiaolong CAI Xiangyu GAO Wenke CHEN Qiuyang | 2021 | China's Refractories2021,30,3: | 3 |
| 12 | Association between diabetes mellitus,hypertension,hyperlipidemia,chronic viral hepatitis,and the risk of multiple myeloma:a case-control study显示文摘Objective This case-control study aimed to investigate whether diabetes mellitus(DM),hypertension,hyperlipidemia,and chronic viral hepatitis are risk factors for multiple myeloma(MM).Moreover,the clinical characteristics of MM patients with or without the abovementioned exposure factors were analyzed.Methods In total,340 MM patients and 680 patients with benign diseases who were hospitalized from January 2012 to December 2017 were classified under the case group and control group,respectively.Data about medical history of DM,hypertension,hyperlipidemia and chronic viral hepatitis were collected by reviewing medical records.Univariate and multivariate analyses were conducted to compare the history of DM,hypertension,hyperlipidemia,and viral hepatitis between the two groups.Considering DM,hypertension,hyperlipidemia,and chronic viral hepatitis as exposure factors,clinical characteristics,such as renal function and presence of fungal and other types of infections,between the exposed and nonexposed groups were analyzed.Results No significant difference was observed in the prevalence of DM,hypertension,and hyperlipidemia between the case and control groups.MM patients had a higher prevalence of chronic viral hepatitis than those with benign diseases.No significant difference was observed in the prevalence of renal dysfunction,fungal infection,and non-fungal infections in MM patients with or without DM,hypertension,and hyperlipidemia.MM patients with chronic viral hepatitis had a significantly higher prevalence of nonfungal infections during hospitalization than those without.Conclusion No significant association was noted between MM and DM,hypertension,and hyperlipidemia.Chronic viral hepatitis is correlated to a significantly higher risk of MM,and MM patients with chronic viral hepatitis were more susceptible to non-fungal infections during hospitalization.Although a non-significant trend was observed in this study,we believe that DM and hypertension might be associated with a higher risk of MM.Thus,large-scale studies must be conducted to validate the results of the current study. | Gang Zhou Xiangyu Meng Shangqin Liu | 2020 | Oncology and Translational Medicine2020,6,2: | 3 |
| 13 | D2 lymphadenectomy with complete mesogastrium excision vs. conventional D2 gastrectomy for advanced gastric cancer显示文摘Background: The complete mesogastrium excision (CME) based on D2 radical gastrectomy is believed to significantly reduce the local-regional recurrence compared with D2 radical gastrectomy in advanced gastric cancer, and it is widely used in China. This study aimed to explore whether D2 + CME is superior to D2 on surgical outcomes during gastrectomy from Chinese data.Methods: Feasible studies comparing the D2 + CME (D2 + CME group) and D2 (D2 group) published up to March 2020 are searched from electronic databases. The data showing surgical and complication outcomes are extracted to be pooled and analyzed.Results: Fourteen records including 1352 patients were included. The D2 + CME group had a shorter mean operative time (weighted mean difference [WMD] = -16.72 min, 95% confidence interval [CI]: -26.56 to - 6.87 min,P < 0.001), lower mean blood loss (WMD = -39.08 mL, 95% CI: -49.94 to -28.21 mL,P < 0.001), higher mean number of retrieved lymph nodes (WMD = 2.13, 95% CI: 0.58-3.67,P = 0.007), shorter time to first flatus (WMD =-0.31 d, 95% CI: -0.53 to - 0.10 d,P = 0.005), and postoperative hospital days (WMD =-1.09, 95% CI: -1.92 to -0.25,P = 0.010) than the D2 group. Subgroup analysis suggested that the advantages from the D2 + CME group were obvious in traditional open radical gastrectomy, proximal gastrectomy, and distal gastrectomy compared with D2 group. The evaluations of post-operative complications showed that the patients who underwent D2 + CME had a lower incidence of post-operative complications than the patients who underwent D2 surgery alone (relative risk [RR] = 0.65, 95% CI: 0.45-0.87,P = 0.003). The D2 radical gastrectomy plus CME improved 3-year overall survival (OS) (RR = 1.16, 95% CI: 1.02-1.32,P = 0.020) and lowered the local recurrence rate (RR = 0.51, 95% CI: 0.28-0.94,P = 0.030). The patients undergoing laparoscopic surgery or total gastrectomy had more significant advantages compared between D2 + CME and D2 groups in 3-year OS.Conclusion: The data from China show that D2 radical gastrectomy plus CME are reliable procedures and safety compared to D2 radical gastrectomy with faster recovery, lower risk, and better prognosis. | Xiangyu Meng Lu Wang Guangcong Liu Jun Zhang Yue Wang Dong Yang Guoliang Zheng Tao Zhang Zhichao Zheng Yan Zhao | 2022 | Chinese Medical Journal2022,,10: | 3 |

| 15 | Converting Escherichia coli MG1655 into a chemical overproducer through inactivating defense system against exogenous DNA显示文摘Escherichia coli strain K-12 MG1655 has been proposed as an appropriate host strain for industrial production.However,the direct application of this strain suffers from the transformation inefficiency and plasmid instability.Herein,we conducted genetic modifications at a serial of loci of MG1655 genome,generating a robust and universal host strain JW128 with higher transformation efficiency and plasmid stability that can be used to efficiently produce desired chemicals after introducing the corresponding synthetic pathways.Using JW128 as the host,the titer of isobutanol reached 5.76 g/L in shake-flask fermentation,and the titer of lycopene reached 1.91 g/L in test-tube fermentation,40-fold and 5-fold higher than that of original MG1655,respectively.These results demonstrated JW128 is a promising chassis for high-level production of value-added chemicals. | Jingge Wang Chaoyong Huang Kai Guo Lianjie Ma Xiangyu Meng Ning Wang Yi-Xin Huo | 2020 | Synthetic and Systems Biotechnology2020,5,4: | 2 |

| 17 | A Novel Routing Method for Social Delay-Tolerant Networks显示文摘The lack of continuous connectivity and a complete path from source to destination makes node communication quite difficult in Delay-Tolerant Networks(DTNs). Most studies focus on routing problems in idealized network environments without considering social properties. Communication devices are carried by individuals in many DTNs; therefore, DTNs are unique social networks to some extent. To design efficient routing protocols for DTNs, it is important to analyze their social properties. In this paper, a more accurate and comprehensive metric for detecting the quality of the relationships between nodes is proposed, by considering the contact time, contact frequency, and contact regularity. An overlapping hierarchical community detection method is designed based on this new metric, and a tree structure is built. Furthermore, we exploit the overlapping community structure and the tree structure to provide message-forwarding paths from the source node to the destination node.The simulation results show that our Routing method based on Overlapping hierarchical Community Detection(ROCD) achieves better delivery rate than SimBet and Bubble Rap, the classic routing protocols, without affecting the average delay. | Xiangyu Meng Gaochao Xu Tingting Guo Yongjian Yang Wenxu Shen Kuo Zhao | 2019 | Tsinghua Science and Technology2019,24,1: | 2 |
