2Opening and evolution of the South China Sea constrained by studies on volcanic rocks:Preliminary results and a research design显示文摘The South China Sea (SCS) is characterized by abundant seamounts, which provide important information about the evolution of the SCS and related deep processes. Cenozoic volcanism in the SCS and its surroundings comprises three stages relative to the spreading of the SCS:prespreading (>32 Ma), syn-spreading (32-16 Ma), and post-spreading (<16 Ma). The pre-spreading magmatism predominantly occurs on the northern margin of the SCS and in South China coastal areas and shows a bi-modal affinity. The syn-spreading magmatic activity was very limited on the periphery of the SCS, but may be concentrated in the SCS. However, seafloor samples of this stage are not available yet because of overlying thick sedimentary deposits. Post-spreading magmatism is widespread in the central and southwest sub-basins of the SCS, Hainan Island, Leizhou Peninsula, Thailand, and Vietnam. These are mainly alkali basalts with subordinate tholeiites, and display OIB-type geochemical characteristics. The Dupal isotope anomaly and presence of high-magnesian olivine phenocrysts suggests their possible derivation from the Hainan mantle plume. The temporal and spatial distribution of Cenozoic volcanism in the SCS and its surroundings may be accounted for either by plate stress re-organization before and after SCS spreading, or by ridge suction of plume flow during opening of the SCS. If the latter is the case, the volcanic rocks within the SCS basin may not be typical mid-ocean ridge basalts (MORB). It remains puz-zling, however, that the transition between the South China continental margin and the SCS basin does not have features typical of a volcanic rifted margin. Clearly, the relationship between mantle plume and SCS opening needs further evaluation. A better un-derstanding of the link between deep processes and opening of the SCS not only requires enhanced studies on igneous petrogene-sis, but also is heavily dependent on systematic sampling of seafloor rocks.XU YiGang WEI JingXian QIU HuaNing ZHANG HuiHuang HUANG XiaoLong 2012Chinese Science Bulletin2012,57,24:43
3Effects of Tai Ji Quan training on gait kinematics in older Chinese women with knee osteoarthritis: A randomized controlled trial显示文摘Background: Although Tai Ji Quan has been shown to relieve pain and improve functional mobility in people with knee osteoarthritis(OA), little is known about its potential benefits on gait characteristics among older Chinese women who have a high prevalence of both radiographic and symptomatic knee OA. This study aims to assess the efficacy of a tailored Tai Ji Quan intervention on gait kinematics for older Chinese women with knee OA.Methods: A randomized controlled trial involving 46 older women in Shanghai, China, with clinically diagnosed knee OA. Randomized(1:1)participants received either a 60 min Tai Ji Quan session(n = 23) 3 times weekly or a 60 min bi-weekly educational session(n = 23) for 24 weeks.Primary outcomes were changes in gait kinematic measures from baseline to 24 weeks. Secondary outcomes included changes in scores on the Western Ontario and Mc Master University Osteoarthritis Index(WOMAC) and Short Physical Performance Battery(SPPB).Results: After 24 weeks the Tai Ji Quan group demonstrated better performance in gait velocity(mean difference, 8.40 cm/s, p = 0.01), step length(mean difference, 3.52 cm, p = 0.004), initial contact angle(mean difference, 2.19°, p = 0.01), and maximal angle(mean difference, 2.61°,p = 0.003) of flexed knees during stance phase compared to the control group. In addition, the Tai Ji Quan group showed significant improvement in WOMAC scores(p < 0.01)(mean difference,-4.22 points in pain, p = 0.002;-2.41 points in stiffness, p < 0.001;-11.04 points in physical function, p = 0.006) and SPPB scores(mean difference, 1.22 points, p < 0.001).Conclusion: Among older Chinese women with knee OA, a tailored Tai Ji Quan intervention improved gait outcomes. The intervention also improved overall function as indexed by the WOMAC and SPPB. These results support the use of Tai Ji Quan for older Chinese adults with knee OA to both improve their functional mobility and reduce pain symptomatology.Qingguang Zhu Lingyan Huang Xie Wu Lin Wang Yunya Zhang Min Fang Yu Liu JingXian Li 2016Journal of Sport and Health Science2016,5,3:14
4Experimental investigation on drag reduction in turbulent boundary layer over superhydrophobic surface by TRPIV显示文摘This study aims at the mechanism of drag reduction in turbulent boundary layer(TBL) with superhydrophobic surface.Comparing the time-resolved particle image velocimetry(TRPIV) measurement results with that of hydrophilic surface,the drag reduction rate over a superhydrophobic surface is approximately10%.To investigate the characteristics of coherent structure in a drag-reduced TBL with superhydrophobic surface,a modified multi-scale spatial locally-averaged structure function is proposed for detecting coherent structure.The conditional sampling and spatial phase-lock average methods are employed to obtain the topology of physical quantities like the velocity fluctuation,spanwise vorticity,and Reynolds stress during eject and sweep process.The results indicate that the suppression of coherent structure burst in the near-wall region is the key mechanism in reducing the skin friction drag for TBL over superhydrophobic surface.Haiping Tian Jingxian Zhang Erdan Wang Zhaohui Yao Nan Jiang 2015Theoretical & Applied Mechanics Letters2015,5,1:7
5Comparison of nonhuman primates identified the suitable model for COVID-19显示文摘Identification of a suitable nonhuman primate(NHP)model of COVID-19 remains challenging.Here,we characterized severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection in three NHP species:Old World monkeys Macaca mulatta(M.mulatta)and Macaca fascicularis(M.fascicularis)and New World monkey Callithrix jacchus(C.jacchus).Infected M.mulatta and M.fascicularis showed abnormal chest radiographs,an increased body temperature and a decreased body weight.Viral genomes were detected in swab and blood samples from all animals.Viral load was detected in the pulmonary tissues of M.mulatta and M.fascicularis but not C.jacchus.Furthermore,among the three animal species,M.mulatta showed the strongest response to SARS-CoV-2,including increased inflammatory cytokine expression and pathological changes in the pulmonary tissues.Collectively,these data revealed the different susceptibilities of Old World and New World monkeys to SARS-CoV-2 and identified M.mulatta as the most suitable for modeling COVID-19.Shuaiyao Lu Yuan Zhao Wenhai Yu Yun Yang Jiahong Gao Junbin Wang Dexuan Kuang Mengli Yang Jing Yang Chunxia Ma Jingwen Xu Xingli Qian Haiyan Li Siwen Zhao Jingmei Li Haixuan Wang Haiting Long Jingxian Zhou Fangyu Luo Kaiyun Ding Daoju Wu Yong Zhang Yinliang Dong Yuqin Liu Yinqiu Zheng Xiaochen Lin Li Jiao Huanying Zheng Qing Dai Qiangming Sun Yunzhang Hu Changwen Ke Hongqi Liu Xiaozhong Peng 2020Signal Transduction and Targeted Therapy2020,5,1:5
6Monitoring paddy rice phenology using time series MODIS data over Jiangxi Province,China显示文摘Paddy rice is one of the most important crops in the world.Accurate estimation and monitoring of paddy rice phenology is necessary for management and yield prediction.Remotely sensed time-series data are essential for estimation of crop phenology stages across large areas.Here,the paddy rice phenological stages(i.e.,transplanting,tillering,heading,and harvesting)were detected in Jiangxi Province,China.A comparison study was conducted using ground observation data from 10 agricultural meteorological stations,collected between 2006 and 2008.The phenological stages were detected using Moderate Resolution Imaging Spectroradiometer(MODIS)time-series enhanced vegetation index(EVI)data.Savitzky-Golay filter and wavelet transform were used to reduce the noise in the time-series EVI data and reconstruct the smoothed EVI time-series profile.Key phenological stages of double-cropping rice were detected using the characteristics of the smoothed EVI profile.The root mean square errors(RMSEs)for each stage were ±10 days around the ground observation data.The results suggest that Savitzky-Golay filter and wavelet transform are promising approaches for reconstructing high-quality EVI time-series data.Moreover,the phenological stages of double-cropping rice could be detected using time-series MODIS EVI data smoothed by Savitzky-Golay filter and wavelet transform.Li Shihua Xiao Jiangtao Ni Ping Zhang Jing Wang Hongshu Wang Jingxian 2014International Journal of Agricultural and Biological Engineering2014,7,6:3
7The preventive effect of vaccine prophylaxis on severe respiratory syncytial virus infection:A meta-analysis显示文摘Respiratory syncytial virus(RSV) is the key underlying cause of acute lower respiratory tract infection in infants; however, no licensed vaccine against RSV infection is currently available. This study was undertaken to assess the preventive effect of vaccine on RSV infection. In this metaanalysis, 1,792 published randomized clinical trials of RSV vaccines from Jan 1973 to Sep 2015 were examined. Among thirteen studies that met the inclusion criteria, eleven studies estimated the impact of RSV vaccines and four studies estimated the effect of adjuvants. The odds ratios(ORs) were 0.31(95% CI, 0.15–0.67) and 0.62(95% CI, 0.29–1.34), respectively. We found that RSV subunit vaccines can significantly reduce the incidence of RSV infection and that whether vaccination with adjuvant therapy was an effective strategy still remained to be studied. This analysis of the preventive effect of vaccines on RSV infection has direct applications for the prevention of RSV infections.Tongna Zhu Chuanlong Zhang Li Yu Jingxian Chen Huan Qiu Weiwei Lyu Shenghai Huang 2015Virologica Sinica2015,30,5:2
8Effect of Taijiquan practice versus wellness education on knee pro-prioception in patients with knee osteoarthritis:a randomized con-trolled trial显示文摘OBJECTIVE: To determine the effects of Taijiquan practice on knee proprioception in patients with knee osteoarthritis(OA).METHODS: We conducted a randomized controlled trial comparing Taijiquan with a control condition(wellness education) in patients with knee OA. The patients participated in either a 60-min Taijiquan session three times weekly or a 60-min weekly educational session, for 24 consecutive weeks. The primary outcomes were changes in knee proprioception. Secondary outcomes were changes in the Western Ontario and Mc Master University Osteoarthritis Index(WOMAC).RESULTS: After 24 weeks, compared with the control group, the Taijiquan group demonstrated better improvements in the joint position sense in knee flexion(left:-2.12°; right:-2.02°), and knee extension(left:-2.22°; right:-1.54°). In addition,the Taijiquan group showed significantly greater improvements in the WOMAC scores(P < 0.05) for knee pain(left:-3.17 points; right:-3.74 points),stiffness(left:-2.43 points; right:-2.13 points),and physical function(left:-10.99 points; right:-8.00 points), compared with the control group.CONCLUSION: A 24-week Taijiquan practice resulted in a significant improvement in knee proprioception in patients with knee OA. The present findings add increasing evidence regarding the clinical benefits of Taijiquan as a therapeutic modality for patients to improve the reflex protection of knee joints against potentially harmful forces.Zhu Qingguang Huang Lingyan Li Jingxian Mao Lijuan Zhang Yunya Min Fang Yu Liu 2017Journal of Traditional Chinese Medicine2017,37,6:2
9Long- versus short-interval follow-up after resection of hepatocellular carcinoma: a retrospective cohort study显示文摘Background:Average postoperative follow-up intervals vary in patients undergoing hepatocellular carcinoma(HCC)resection because of limited evidence regarding the optimal interval.We aimed to compare the associations of long-versus short-interval follow-up with survival and recurrence in risk-stratified HCC patients.Methods:We performed a retrospective cohort study between 2007 and 2014.In total,1227 patients treated by curative resection of Barcelona Clinic Liver Cancer stage A or B HCC were stratified as having a low(n=865)or high(n=362)risk of early recurrence(within the first 2 years after resection)based on prognostic factors identified by the least absolute shrinkage and selection operation algorithm.Patients were further classified into long-interval(every 4-6 months)and short-interval(every 2-4 months)follow-up subgroups based on follow-up within 2 years after resection(low risk,long vs.short:n=390 vs.n=475;high-risk,long vs.short:n=149 vs.n=213).Results:The short-interval follow-up did not prolong overall survival in either the low-risk(hazard ratio[HR]=1.152;95%confidence interval[CI]0.720-1.843)or high-risk(HR=1.213;95%CI 0.702-2.094)patients.Early recurrence occurred in 401 patients.For high-risk patients,the short-interval follow-up subgroup exhibited smaller intrahepatic recurrence than did the long-interval group(2.6 vs.3.5 cm,respectively,P=0.045).However,no significant difference in the rate of Barcelona Clinic Liver Cancer stage 0/A recurrence was found between the long-and short-interval follow-up groups in either low-or high-risk patients(63.1%vs.68.2%,respectively,P=0.580;31.3%vs.41.5%,respec-tively,P=0.280).The rate of curative intent treatment for recurrence(34.5%vs.39.7%,respectively,P=0.430;14.6%vs.20.3%,respectively,P=0.388)was also similar between the follow-up groups for low-and high-risk patients.Conclusions:Shortening the postoperative follow-up interval from every 4-6 months to every 2-4 months within the first 2 years after resection did not increase the rate of curative intent treatment or prolong the overall survival of patients with Barcelona Clinic Liver Cancer stage A or B HCC.Wei He Yun Zheng Ruhai Zou Jingxian Shen Junping Yang Jiliang Qiu Qiang Tao Wenwu Liu Zhiwen Yang Yuanping Zhang Binkui Li Yunfei Yuan 2018Cancer Communications2018,38,1:2
10Synthesis and characterization of caprolactone based polyurethane with degradable and antifouling performance显示文摘In this work,a degradable polyurethane composed of caprolactone(CL)and L-Lactide(LLA)as soft segments,and 4,40-methylenebis(cyclohexyl isocyanate)(H12 MDI)and polytetramethylene ether glycol(PTMEG)as hard segments,was prepared.Hydrolytic degradation experiment revealed that the degradable polyurethane(PU)could be degraded in artificial seawater.It also showed that caprolactone-copolyurethane(CL-PU)copolymer with higher crystallinity degraded much slower in artificial seawater.However,the introduction of LLA resulted in an increase in the hydrophilicity and reduction in the crystallinity of degradable PU,as demonstrated by the contact angle analysis.The result of the scanning electron microscope showed that the surface of degradable PU renewed under static condition.Moreover,degradable PU was able to be used as a carrier,and it controlled the release rate of 4,5-dichloro-2-octyl-isothiazolone(DCOIT).The anti-diatom(Navicula incerta)test demonstrated that the(caprolactone-co-L-lactide)-co-polyurethane 4(CL/LAx-PU4)with DCOIT contents prevented the adhesion of diatom Navicula incerta(88.37%reduction)due to their self-polishing and the release of antifoulants.Therefore,the degradable PU consisted of CL,LLA,and DCOIT could be a durable resin with good antifouling activity for the application in the marine anti-biofouling field.Abid Ali Lina Song Jiankun Hu Jingxian Jiang Qingqing Rao Muhammad Shoaib Shah Fahad Yongjie Cai Xiaoli Zhan Fengqiu Chen Qinghua Zhang 2021Chinese Journal of Chemical Engineering2021,34,6:2

12Fabrication of lanthanum doped yttria transparent ceramics显示文摘Yttria nanocrystalline powder doped with 9% lanthanum was synthesized by co-precipitation method using ammonia for pH adjusting. After calcinations, finer particles with narrow distribution and large surface area were obtained. After dry pressing, samples were sintered at 1500℃―1700℃ for 4 h in vacuum to produce transparent polycrystalline ceramics with uniform grains. Samples with 9 mol% lanthanum were transparent in visible light after being sintered at 1500℃ for 4 h. The grain sizes increased with lanthanum doping compared with those of pure yttria transparent ceramic sintered at the same conditions. Relative density of the transparent ceramic was 99.7%. The in-line transmittance was 73% at 580 nm wavelength after milling and polishing.HUANG YiHua JIANG DongLiang ZHANG JingXian LIN QingLing 2009Chinese Science Bulletin2009,54,12:2
13Slippery Properties and the Robustness of Lubricant-impregnated Surfaces显示文摘Inspired by nepenthes pitcher plants,Lubricant-Impregnated Surfaces(LISs)are surfaces with lubricant infused in the textures which form slippery interfaces.In this paper,we investigated slippery properties and the robustness of LISs with different micro-texture topologies(i.e.,no textures,micro-pillar textures and micro hole textures),including original LISs and LISs rinsed by water.We measured the static contact angle,sliding angle and droplet motions on the LISs,using a contact angle instrument and a Particle Image Velocimetry(P1V)system.Similar contact angles and small sliding angles were observed on all original LISs,which indicated that an oil-layer existed on each LIS's interface.After rinsed by water,the sliding angle increased obviously and the slip velocity decreased,which meant that the LISs slippery properties deteriorated in different degrees.Among all the LISs in our experiments,LIS with micro pillar textures has the best slippery performance and robustness before and after rinsed.We found that the LISs'slippery properties were closely related to the states of the oil-layer on the interface,which were changed after rinsed.For the LIS with micro pillar textures,a thin layer of lubricant can sustain on the interface even after rinse,which made the droplet slide smoothly on the surface,with a lower sliding angle and a larger sliding velocity.This indicates that the proper micro-texture will enhance the slippery property and make it last longer.Jingxian Zhang Zhaohui Yao 2019Journal of Bionic Engineering2019,16,2:1

20Effectiveness of Liu-zi-jue exercise on coronavirus disease 2019 in the patients: a randomized controlled trial显示文摘OBJECTIVE: The aim of this study was to examine the effect of Liu-zi-jue exercise on the respiratory symptoms, quality of life, and mental health of patients with mild coronavirus disease 2019(COVID-19). METHODS: A single-center randomized controlled trial was conducted with 104 patients with mild COVID-19. The patients were randomly assigned to the Liu-zi-jue plus conventional therapy group and conventional therapy group. The outcome measures included Modified Borg Dyspnea Scale(MBDS) score, Patient Health Questionnaire-9(PHQ-9) score, Fatigue Scale-14(FS-14), respiratory symptoms, and vital signs. Data were collected on the first and sixth days of hospitalization and on the discharge day. RESULTS: Repeated-measures ANOVA revealed that the whole scales all showed a downward trend in the two groups(all P < 0.05). The results of single-group effect suggested that the whole scale score in the intervention group was significantly lower than that in the control group at the sixth day of hospitalization. Compared with the control group, only the MBDS, expectoration, and FS-14 scores showed significantly lower scores at the discharge day(P < 0.001, P = 0.011, P = 0.002). Comparison within the group showed that all the variables were significantly different at the three time points with a decreasing trend(P < 0.05), except for the PHQ-9 and expectoration scores(P = 0.331, 0.052). All patients’ vital signs remained within a stable normal range throughout the hospital stay. CONCLUSION: The results suggested that Liu-zi-jue exercise as a complementary and alternative therapy showed beneficial effects on improving the symptoms(shortness of breath, fatigue, and cough), quality of life, and mental health of patients with mild COVID-19.ZHU Qingguang ZHANG Shuaipan LI Jingxian SUN Wuquan CHENG Wei ZHAN Chao CHENG Yanbin FANG Lei FANG Min 2022Journal of Traditional Chinese Medicine2022,42,6:1
