1Acupuncture at Waiguan(SJ5) and sham points influences activation of functional brain areas of ischemic stroke patients: a functional magnetic resonance imaging study显示文摘Most studies addressing the specificity of meridians and acupuncture points have focused mainly on the different neural effects of acupuncture at different points in healthy individuals. This study examined the effects of acupuncture on brain function in a pathological context. Sixteen patients with ischemic stroke were randomly assigned to true point group(true acupuncture at right Waiguan(SJ5)) and sham point group(sham acupuncture). Results of functional magnetic resonance imaging revealed activation in right parietal lobe(Brodmann areas 7 and 19), the right temporal lobe(Brodmann area 39), the right limbic lobe(Brodmann area 23) and bilateral occipital lobes(Brodmann area 18). Furthermore, inhibition of bilateral frontal lobes(Brodmann area 4, 6, and 45), right parietal lobe(Brodmann areas 1 and 5) and left temporal lobe(Brodmann area 21) were observed in the true point group. Activation in the precuneus of right parietal lobe(Brodmann area 7) and inhibition of the left superior frontal gyrus(Brodmann area 10) was observed in the sham group. Compared with sham acupuncture, acupuncture at Waiguan in stroke patients inhibited Brodmann area 5 on the healthy side. Results indicated that the altered specificity of sensation-associated cortex(Brodmann area 5) is possibly associated with a central mechanism of acupuncture at Waiguan for stroke patients.Ji Qi Junqi Chen Yong Huang Xinsheng Lai Chunzhi Tang Junjun Yang Hua Chen Shanshan Qu 2014Neural Regeneration Research2014,9,3:19
2Integral stormwater management master plan and design in an ecological community显示文摘Urban stormwater runoff nearly discharges directly into bodies of water through gray infrastructure in China,such as sewers,impermeable ditches,and pump stations.As urban flooding,water shortage,and other environment problems become serious,integrated water environment management is becoming increasingly complex and challenging.At more than 200 ha,the Oriental Sun City community is a large retirement community located in the eastern side of Beijing.During the beginning of its construction,the project faced a series of serious water environment crises such as eutrophication,flood risk,water shortage,and high maintenance costs.To address these issues,an integral stormwater management master plan was developed based on the concept of low impact development(LID).A large number of LID and green stormwater infrastructure(GSI)approaches were designed and applied in the community to replace traditional stormwater drainage systems completely.These approaches mainly included bioretention(which captured nearly 85th percentile volume of the annual runoff in the site,nearly 5.4×105m3annually),swales(which functioned as a substitute for traditional stormwater pipes),waterscapes,and stormwater wetlands.Finally,a stormwater system plan was proposed by integrating with the gray water system,landscape planning,an architectural master plan,and related consultations that supported the entire construction period.After more than 10 years of planning,designing,construction,and operation,Oriental Sun City has become one of the earliest modern large-scale LID communities in China.Moreover,the project not only addressed the crisis efficiently and effectively,but also yielded economic and ecological benefits.Wu Che Yang Zhao Zheng Yang Junqi Li Man Shi 2014Journal of Environmental Sciences2014,26,9:13

5Model predictive control for hybrid vehicle ecological driving using traffic signal and road slope information显示文摘This paper presents development of a control system for ecological driving of a hybrid vehicle. Prediction using traffic signal and road slope information is considered to improve the fuel economy. It is assumed that the automobile receives traffic signal information from intelligent transportation systems(ITS). Model predictive control is used to calculate optimal vehicle control inputs using traffic signal and road slope information. The performance of the proposed method was analyzed through computer simulation results. Both the fuel economy and the driving profile are optimized using the proposed approach. It was observed that fuel economy was improved compared with driving of a typical human driving model.Kaijiang YU Junqi YANG Daisuke YAMAGUCHI 2015Control Theory and Technology2015,13,1:9
6Acupuncture at Waiguan (TE5) influences activation/deactivation of functional brain areas in ischemic stroke patients and healthy people A functional MRI study显示文摘In the present study, 10 patients with ischemic stroke in the left hemisphere and six healthy controls were subjected to acupuncture at right Waiguan (TE5). In ischemic stroke subjects, functional MRI showed enhanced activation in Broadmann areas 5, 6, 7, 18, 19, 24, 32, the hypothalamic inferior lobe, the mamillary body, and the ventral posterolateral nucleus of the left hemisphere, and Broadmann areas 4, 6, 7, 18, 19 and 32 of the right hemisphere, but attenuated activation of Broadmann area 13, the hypothalamic inferior lobe, the posterior lobe of the tonsil of cerebellum, and the culmen of the anterior lobe of hypophysis, in the left hemisphere and Broadmann area 13 in the right hemisphere. In ischemic stroke subjects, a number of deactivated brain areas were enhanced, including Broadmann areas 6, 11, 20, 22, 37, and 47, the culmen of the anterior lobe of hypophysis, alae lingulae cerebella, and the posterior lobe of the tonsil of cerebellum of the left hemisphere, and Broadmann areas 8, 37, 45 and 47, the culmen of the anterior lobe of hypophysis, pars tuberalis adenohypophyseos, inferior border of lentiform nucleus, lateral globus pallidus, inferior temporal gyrus, and the parahippocampal gyrus of the right hemisphere. These subjects also exhibited attenuation of a number of deactivated brain areas, including Broadmann area 7. These data suggest that acupuncture at Waiguan specifically alters brain function in regions associated with sensation, vision, and motion in ischemic stroke patients. By contrast, in normal individuals, acupuncture at Waiguan generally activates brain areas associated with insomnia and other functions.Junqi Chen Yong Huang Xinsheng Lai Chunzhi Tang Junjun Yang Hua Chen Tongjun Zeng Junxian Wu Shanshan Qu 2013Neural Regeneration Research2013,8,3:8
7Is urban development an urban river killer? A case study of Yongding Diversion Channel in Beijing, China显示文摘The high population and concrete environment alter urban areas by changing temperature, rainfall runoff, and water resource utilization activities. This study was conducted to investigate the water quality features of the Yongding Diversion Channel in Beijing, China, and its relationship with rainfall and urban development. Monthly water quality data were obtained from April to October of 2004 at monitoring sites of Sanjiadian, Gaojing, Luodaozhuang, and Yuyuangtan. The monthly water quality grades from 2007 to 2011 were also investigated and compared with those of other rivers. Dissolved oxygen and pH showed greater decreases after one or two moderate rainfall events than several light rainfall events. The potassium permanganate index(CODMn), ammonia nitrogen(NH3-N) and total phosphorus(TP) increased more after several light rainfall events than after one or two moderate or heavy rainfall events. Pollutant concentrations(CODMn, NH3-N, TP) in downstream regions showed greater changes than those in upstream areas after heavy rainfall events. Intense human activities around the channel greatly influenced the water quality of the channel in rainy season because of runoff pollution; however, heavy rainfall had a strong dilution effect on the pollutant concentrations in rivers. Overall, urban development has obviously deteriorated the water quality of the Yongding Diversion Channel as indicated by an increase in the water quality index from 3.22 in 2008 to 4.55 in2010. The Pearson correlation between monthly rainfall and water quality indices from 2007 to 2011ranged from 0.1286 to 0.6968, generally becoming weaker as rainfall and rainfall runoff became more random and extreme.Xi Wang Junqi Li Yingxia Li Zhenyao Shen Xuan Wang Zhifeng Yang Inchio Lou 2014Journal of Environmental Sciences2014,26,6:8
8Expert consensus on dental caries management显示文摘Dental Caries is a kind of chronic oral disease that greatly threaten human being’s health.Though dentists and researchers struggled for decades to combat this oral disease,the incidence and prevalence of dental caries remain quite high.Therefore,improving the disease management is a key issue for the whole population and life cycle management of dental caries.So clinical difficulty assessment system of caries prevention and management is established based on dental caries diagnosis and classification.Dentists should perform oral examination and establish dental records at each visit.When treatment plan is made on the base of caries risk assessment and carious lesion activity,we need to work out patient-centered and personalized treatment planning to regain oral microecological balance,to control caries progression and to restore the structure and function of the carious teeth.And the follow-up visits are made based on personalized caries management.This expert consensus mainly discusses caries risk assessment,caries treatment difficulty assessment and dental caries treatment plan,which are the most important parts of caries management in the whole life cycle.Lei Cheng Lu Zhang Lin Yue Junqi Ling Mingwen Fan Deqin Yang Zhengwei Huang Yumei Niu Jianguo Liu Jin Zhao Yanhong Li Bin Guo Zhi Chen Xuedong Zhou 2022International Journal of Oral Science2022,14,2:8
9Expert consensus on regenerative endodontic procedures显示文摘Regenerative endodontic procedures(REPs)is a biologic-based treatment modality for immature permanent teeth diagnosed with pulp necrosis.The ultimate objective of REPs is to regenerate the pulp-dentin complex,extend the tooth longevity and restore the normal function.Scientific evidence has demonstrated the efficacy of REPs in promotion of root development through case reports,case series,cohort studies,and randomized controlled studies.However,variations in clinical protocols for REPs exist due to the empirical nature of the original protocols and rapid advancements in the research field of regenerative endodontics.The heterogeneity in protocols may cause confusion among dental practitioners,thus guidelines and considerations of REPs should be explicated.This expert consensus mainly discusses the biological foundation,the available clinical protocols and current status of REPs in treating immature teeth with pulp necrosis,as well as the main complications of this treatment,aiming at refining the clinical management of REPs in accordance with the progress of basic researches and clinical studies,suggesting REPs may become a more consistently evidence-based option in dental treatment.Xi Wei Maobin Yang Lin Yue Dingming Huang Xuedong Zhou Xiaoyan Wang Qi Zhang Lihong Qiu Zhengwei Huang Hanguo Wang Liuyan Meng Hong Li Wenxia Chen Xiaoying Zou Junqi Ling 2022International Journal of Oral Science2022,14,4:5
10Degradation of simulated organic wastewater by advanced oxidation with oxidants generated from oxygen reduction显示文摘The degradation capacity of advanced oxidants generated from oxygen reduction was investigated in model effluent containing chlorobenzene, aniline and benzene through the advanced oxidation processes(AOPs). Intermediate products of the degradation process were determined by GC–MS, and they contributed to specify the degradation pathways of monoaromatic compounds. The study particularly focused on the influence of the dosage of the oxidant, pH and the initial concentration of organic compounds on the degradation effectiveness.When the dosage of oxidant was 4 wt% and the pH was 7, the maximum degradation rates of 74.83% chlorobenzene, 70.32% aniline and 37.69% benzene were achieved. Furthermore, microwave was applied to intensify the oxidation process under optimal operation conditions, and the degradation rates were increased to 87.85% chlorobenzene, 89.11% aniline and 39.03% benzene, respectively.Yi Ouyang Qing Xu Yang Xiang Wei Liu Junqi Du 2019Chinese Journal of Chemical Engineering2019,27,4:5

12Abrogation of Hn RNP L enhances anti-PD-1 therapy efficacy via diminishing PD-L1 and promoting CD8^(+) T cell-mediated ferroptosis in castration-resistant prostate cancer显示文摘Owing to incurable castration-resistant prostate cancer(CRPC)ultimately developing after treating with androgen deprivation therapy(ADT),it is vital to devise new therapeutic strategies to treat CRPC.Treatments that target programmed cell death protein 1(PD-1)and programmed death ligand-1(PD-L1)have been approved for human cancers with clinical benefit.However,many patients,especially prostate cancer,fail to respond to anti-PD-1/PD-L1 treatment,so it is an urgent need to seek a support strategy for improving the traditional PD-1/PD-L1 targeting immunotherapy.In the present study,analyzing the data from our prostate cancer tissue microarray,we found that PD-L1 expression was positively correlated with the expression of heterogeneous nuclear ribonucleoprotein L(Hn RNP L).Hence,we further investigated the potential role of Hn RNP L on the PD-L1 expression,the sensitivity of cancer cells to T-cell killing and the synergistic effect with anti-PD-1 therapy in CRPC.Indeed,Hn RNP L knockdown effectively decreased PD-L1 expression and recovered the sensitivity of cancer cells to T-cell killing in vitro and in vivo,on the contrary,Hn RNP L overexpression led to the opposite effect in CRPC cells.In addition,consistent with the previous study,we revealed that ferroptosis played a critical role in T-cell-induced cancer cell death,and Hn RNP L promoted the cancer immune escape partly through targeting YY1/PD-L1 axis and inhibiting ferroptosis in CRPC cells.Furthermore,Hn RNP L knockdown enhanced antitumor immunity by recruiting infiltrating CD8^(+)T cells and synergized with anti-PD-1 therapy in CRPC tumors.This study provided biological evidence that Hn RNP L knockdown might be a novel therapeutic agent in PD-L1/PD-1 blockade strategy that enhanced anti-tumor immune response in CRPC.Xumin Zhou Libin Zou Hangyu Liao Junqi Luo Taowei Yang Jun Wu Wenbin Chen Kaihui Wu Shengren Cen Daojun Lv Fangpeng Shu Yu Yang Chun Li Bingkun Li Xiangming Mao 2022Acta Pharmaceutica Sinica B2022,12,2:4
13Enhanced selective catalytic reduction of NO with NH3 via porous micro-spherical aggregates of Mn–Ce–Fe–Ti mixed oxide nanoparticles显示文摘We rationally designed a high performance denitration(De-NOx) catalyst based on a micrometer-sized spherical Mn–Ce–Fe–Ti(CP-SD)catalyst for selective catalytic reduction(SCR). This was prepared by a co-precipitation and spray drying(CP-SD) method. The catalyst was systematically characterized, and its morphological structure and surface properties were identified. Compare with conventional Mn–Ce–Fe–Ti(CP) catalysts, the Mn–Ce–Fe–Ti(CP-SD) catalyst had superior surface-adsorbed oxygen leading to enhanced 'fast NH3-SCR' reaction. The asobtained Mn–Ce–Fe–Ti(CP-SD) catalyst offered excellent NO conversion and N2 selectivity of 100.0% and 84.8% at 250℃, respectively, with a gas hourly space velocity(GHSV) of 40,000 h-1. The porous micro-spherical structure provides a larger surface area and more active sites to adsorb and activate the reaction gases. In addition, the uniform distribution and strong interaction of manganese, iron, cerium, and titanium oxide species improved H2O and SO2 resistance. The results showed that the Mn–Ce–Fe–Ti(CP-SD) catalyst could be used prospectively as a denitration(De-NOx) catalyst.Junqi Tian Ke Zhang Wei Wang Fu Wang Jianming Dan Shengchao Yang Jinli Zhang Bin Dai Feng Yu 2019Green Energy & Environment2019,4,3:4

1596-Week Treatment of Tenofovir Amibufenamide and Tenofovir Disoproxil Fumarate in Chronic Hepatitis B Patients显示文摘Background and Aims:Tenofovir amibufenamide(TMF)is a novel phosphoramidated prodrug of tenofovir with nonin-ferior efficacy and better bone and renal safety to tenofovir disoproxil fumarate(TDF)in 48 weeks of treatment.Here,we update 96-week comparison results.Methods:Patients with chronic hepatitis B were assigned(2:1)to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks.The virological suppression was defined as HBV DNA levels<20 IU/mL at week 96.Safety was evaluated thoroughly with focusing on bone,renal,and metabolic pa-rameters.Results:Virological suppression rates at week 96 were similar between TMF and TDF group in both HBeAg-positive and HBeAg-negative populations.Noninferior efficacy was maintained in the pooled population,while it was first achieved in patients with HBV DNA≥7 or 8 log10 IU/mL at baseline.Non-indexed estimated glomerular filtration rate for renal safety assessment was adopted,while a smaller decline of which was seen in the TMF group than in the TDF group(p=0.01).For bone mineral density,patients receiv-ing TMF displayed significantly lower reduction levels in the densities of spine,hip,and femur neck at week 96 than those receiving TDF.In addition,the lipid parameters were stable after week 48 in all groups while weight change still showed the opposite trend.Conclusions:TMF maintained similar efficacy at week 96 compared with TDF with continued superior bone and renal safety profiles(NCT03903796).Zhihong Liu Qinglong Jin Yuexin Zhang Guozhong Gong Guicheng Wu Lvfeng Yao Xiaofeng Wen Zhiliang Gao Yan Huang Daokun Yang Enqiang Chen Qing Mao Shide Lin Jia Shang Huanyu Gong Lihua Zhong Huafa Yin Fengmei Wang Peng Hu Qiong Wu Chao Pan Wen Jia Chuan Li Chang’an Sun Junqi Niu Jinlin Hou TMF Study Group 2023Journal of Clinical and Translational Hepatology2023,11,3:3
16Microwave dielectric high-entropy ceramic Li(Gd_(0.2)Ho_(0.2)Er_(0.2)Yb_(0.2)Lu_(0.2))GeO_(4) with stable temperature coefficient for low-temperature cofired ceramic technologies显示文摘High-entropy ceramics are new single-phase materials with at least four cation or anion types.Their large configurational entropy is believed to enhance the simultaneous solubility of many components,which can be used to optimize certain properties.In this work,a high-entropy oxide,Li(Gd_(0.2)Ho_(0.2)Er_(0.2)Yb_(0.2)Lu_(0.2))GeO_(4)(LRG)was explored as a microwave dielectric ceramic for lowtemperature cofired ceramic technologies.The LRG high-entropy ceramic with an olivine structure formed in the sintering temperature range of 1020-1100℃.The minimal distortion(5×10^(-4))of the[RO_(6)]octahedron led to a stable temperature coefficient of resonant frequency(τf)of-5.3 to-2.9 ppm/℃.Optimal microwave dielectric properties were achieved in the high-entropy ceramics at 1080℃ for 4 h with a relative density of 94.9%,a relative permittivity(ε_(r))of 7.2,and a quality factor(Q×f)of 29000 GHz(at15.3 GHz).For low-temperature cofired ceramic technology applications,the sintering temperature of the LRG high-entropy ceramic was reduced to 900℃ by the addition of 3 wt%H_(3)BO_(3),which exhibited outstanding microwave dielectric properties(ε_(r)=7.6,Q×f=11700 GHz,and τ_(f)=-7.4 ppm/℃)and a good chemical compatibility with silver.Huaicheng Xiang Lei Yao Junqi Chen Aihong Yang Haitao Yang Liang Fang 2021Journal of Materials Science & Technology2021,,34:2
17MKRN3 regulates the epigenetic switch of mammalian puberty via ubiquitination of MBD3显示文摘Central precocious puberty(CPP)refers to a human syndrome of early puberty initiation with characteristic increase in hypothalamic production and release of gonadotropin-releasing hormone(GnRH).Previously,loss-of-function mutations in human MKRN3,encoding a putative E3 ubiquitin ligase,were found to contribute to about 30%of cases of familial CPP.MKRN3 was thereby suggested to serve as a‘brake’of mammalian puberty onset,but the underlying mechanisms remain as yet unknown.Here,we report that genetic ablation of Mkrn3 did accelerate mouse puberty onset with increased production of hypothalamic GnRH1.MKRN3 interacts with and ubiquitinates MBD3,which epigenetically silences GNRH1 through disrupting the MBD3 binding to the GNRH1 promoter and recruitment of DNA demethylase TET2.Our findings have thus delineated a molecular mechanism through which the MKRN3-MBD3 axis controls the epigenetic switch in the onset of mammalian puberty.Chuanyin Li Wenli Lu Liguang Yang Zhengwei Li Xiaoyi Zhou Rong Guo Junqi Wang Zhebao Wu Zhiya Dong Guang Ning Yujiang Shi Yinmin Gu Peng Chen Zijian Hao Tianting Han Meiqiang Yang Wei Wang Xuehui Huang Yixue Li Shan Gao Ronggui Hu 2020National Science Review2020,7,3:2
