4Mechanism of Kinect-based virtual reality training for motor functional recovery of upper limbs after subacute stroke显示文摘The Kinect-based virtual reality system for the Xbox 360 enables users to control and interact with the game console without the need to touch a game controller,and provides rehabilitation training for stroke patients with lower limb dysfunctions.However,the underlying mechanism remains unclear.In this study,18 healthy subjects and five patients after subacute stroke were included.The five patients were scanned using functional MRI prior to training,3 weeks after training and at a12-week follow-up,and then compared with healthy subjects.The Fugl-Meyer Assessment and Wolf Motor Function Test scores of the hemiplegic upper limbs of stroke patients were significantly increased 3 weeks after training and at the 12-week follow-up.Functional MRI results showed that contralateral primary sensorimotor cortex was activated after Kinect-based virtual reality training in the stroke patients compared with the healthy subjects.Contralateral primary sensorimotor cortex,the bilateral supplementary motor area and the ipsilateral cerebellum were also activated during hand-clenching in all 18 healthy subjects.Our findings indicate that Kinect-based virtual reality training could promote the recovery of upper limb motor function in subacute stroke patients,and brain reorganization by Kinect-based virtual reality training may be linked to the contralateral sensorimotor cortex.Xiao Bao Yurong Mao Qiang Lin Yunhai Qiu Shaozhen Chen Le Li Ryan S.Cates Shufeng Zhou Dongfeng Huang 2013Neural Regeneration Research2013,8,31:15
5Chemical profiles and anticancer effects of saponin fractions of different polarity from the leaves of Panax notoginseng显示文摘AIM: To evaluate the chemical profiles and cytotoxic effects among the total saponin fraction(TSF), 25% ethanol fraction(25EF), 50% ethanol fraction(50EF), and 85% ethanol fraction(85EF) prepared by macroporous resin from the leaves of Panax notoginseng. METHOD: The simultaneous determination of thirteen main saponins, as well as the chemical profiles of saponin fractions of different polarity, was made by HPLC-DAD and LC-ESI-MSn analysis. The cytotoxic effects were determined against KP4 cells(human pancreatic cancer), NCI-H727 cells(human lung cancer), HepG2 cells(human hepatocellular cancer), and SGC-7901 cells(human gastric adenocarcinoma). RESULTS: Chemical analysis indicated that 85EF possessed the most abundant cytotoxic protopanaxadiol saponins, including the marker saponins F2, 20(R)-Rg3, 20(S)-Rg3, and Rh2. The MTT assay showed that 85EF also had the strongest cytotoxic effects among the four fractions. 25EF showed no anti-proliferative effects, while 50EF and TSF exhibited weak anti-proliferative activity. CONCLUSION: From the aspect of comprehensive utilization of resources, 85EF, enriched with low polarity PPD group saponins, is a new alternative source of anticancer saponins, and a promising botanical preparation for further anticancer studies.MAO Qian LI Yi LI Song-Lin YANG Jie ZHANG Ping-Hu WANG Qiang 2014Chinese Journal of Natural Medicines2014,12,1:12

7Large borehole with multi-lateral branches: A novel solution for exploitation of clayey silt hydrate显示文摘Raising the in situ decomposition rate of natural gas hydrate and increasing the decomposition contact area are two main ways to raise the productivity of hydrate. An exploitation technique based on large borehole with multi-lateral branches (LB & MB) was proposed in this paper. This technique is mainly intended for the clayey silt hydrate reservoir in the South China Sea, and its main purpose is to alleviate the sand output from formation for maintaining the stability of the reservoir and to greatly increase the gas productivity of the reservoir. In this paper, the following aspects were mainly expounded: definition of the basic geometric parameters for layout of multi-lateral branches in clayey silt hydrate reservoir, simulation of the stimulation effect of a typical well profile with two branches, and prediction and simulation of the reservoir failure risk in a well profile with eight branches. The results show that the LB & MB effectively improves the flow field in the formation, raises the productivity of the reservoir and may also help to decrease the produced water-gas ratio (WGR). When the lateral branches spacing is too small, the failure zones around adjacent lateral branches overlap each other, possibly causing reservoir failure in a larger range. Therefore, the geometric parameters of multi-lateral branches depend on the dual control of the productivity and geotechnical risk factor of reservoir. Further study is being carried out, so as to obtain the optimal combination of parameters of multi-lateral branches.Yan-long Li Yi-zhao Wan Qiang Chen Jia-xin Sun Neng-you Wu Gao-wei Hu Fu-long Ning Pei-xiao Mao 2019China Geology2019,2,3:10
8Controlled synthesis of single cobalt atom catalysts via a facile one-pot pyrolysis for efficient oxygen reduction and hydrogen evolution reactions显示文摘Metal-nitrogen doped carbon catalysts(M-N/C) with abundantly accessible M-Nxsites, particularly single metal atom M-N/C(SAM-N/C), have been developed as a substitute for expensive Pt-based catalysts.These catalysts are used to increase the efficiency of otherwise sluggish oxygen reduction reactions(ORR) and hydrogen evolution reactions(HER). However, although the agglomerated metal nanoparticles are usually easy to form, they are very difficult to remove due to the protective surface-coating carbon layers, a factor that significantly hampers SAM-N/C fabrication. Herein, we report a one-step pyrolysis approach to successfully fabricate single cobalt atom Co-N/C(SACo-N/C) by using a Co2+-SCN-coordination compound as the metal precursor. Thanks to the decomposition of Co2+-SCN-compound at lower temperature than that of carbon layer deposition, Co-rich particles grow up to larger ones before carbon layers formation. Even though encapsulated by the carbon layers, it is difficult for the large Co-rich particle to be completely sealed. And thus, it makes the Co atoms possible to escape from incomplete carbon layer, to coordinate with nitrogen atoms, and to form SACo-N/C catalysts. This SACo-N/C exhibits excellent performances for both ORR(half-wave potential of 0.878 V) and HER(overpotential at 10 mA/cm2 of178 m V), and is thus a potential replacement for Pt-based catalysts. When SACo-N/C is integrated into a Zn-O2 battery, battery with high open-circuit voltage(1.536 V) has high peak power density(266 mW/cm2)and large gravimetric energy density(755 mA h/gZn) at current densities of 100 mA/cm2. Thus, we believe that this strategy may offer a new direction for the effective generation of SAM-N/C catalysts.Yao Wang Linhui Chen Zhanxin Mao Lishan Peng Rui Xiang Xianyi Tang Jianghai Deng Zidong Wei Qiang Liao 2019Science Bulletin2019,64,15:10
9Replanting Affects the Tree Growth and Fruit Quality of Gala Apple显示文摘Apple replant disease(ARD) causes the inhibition of root system development, stunts tree growth and so on. To further investigate the effects of ARD on apple fruits, a 25-year-old apple orchard was remediated to establish a replant orchard between November 2008 and March 2009. A rotational cropping orchard was established on an adjacent wheat field. The cultivar and rootstock-scion combination used in the newly established orchards was Royal Gala/M26/Malus hupehensis Rehd. Ripe fruits were collected in mid-August 2011 and mid-August 2012, meanwhile, the following indices were measured: yield per plant; fruit weight; the fruit shape index; the contents of anthocyanin, carotenoid and chlorophyll; the soluble sugar content in the flesh; titratable acid; the sugar-acid ratio; firmness; and aroma components; apple plant ground diameter, plant height increment and the total length of the current-year shoots. The results showed that compared to rotational cropping, continuous cropping yielded statistically significant reductions in fruit weight and yield per plant of 39.8 and 76.5%, respectively. However, there were no changes in the fruit shape index. The anthocyanin and carotenoid contents decreased by 81.7 and 37.7%, respectively, while the chlorophyll content increased by 251.0%. All of these differences in content were statistically significant. The soluble sugar levels and sugar-acid ratio decreased by 25.4 and 60.9%, respectively, but the titratable acid levels and fruit firmness increased by 90.9 and 42.8%, respectively. Ten of the most important esters contributing to the apple aroma were analyzed, and the following changes were observed: hexyl acetate, butyl acetate, hexyl butyrate, acetate-2-methyl butyl, 2-methyl-hexyl butyrate, amyl acetate, butyl butyrate, 2-methyl-butyl butyrate, hexyl propionate and hexyl hexanoate decreased by 25.5, 78.4, 89.1, 55.5, 79.5, 77.2, 86.8, 69.9, 61.2, and 68.1%, respectively. The contents of three other aroma components,(E)-2-hexenal, hexanal and 1-hexanol, significantly increased. Eight characteristic aroma components were found in the rotational cropping fruits: hexyl acetate, butyl acetate, acetate-2-methyl butyl, 2-methyl-hexyl butyrate, amyl acetate, 2-methyl- butyl butyrate, hexyl acetate and hexyl propionate. There were four characteristic ester components(hexyl acetate, butyl acetate, acetate-2-methyl butyl, 2-methyl-hexyl butyrate) and two characteristic aldehyde aroma components((E)-2-hexenal and hexanal) in the continuous cropping fruits. Compared with the rotational cropping fruits, four characteristic ester components were declined and two characteristic aldehyde aroma components were increased. Compared with the control, replanted apple plant ground diameter, plant height increment and the total length of the current-year shoots were reduced by 27.6, 40.6 and 72.2%, respectively.LIU En-tai WANG Gong-shuai LI Yuan-yuan SHEN Xiang CHEN Xue-sen SONG Fu-hai WU Shu-jing CHEN Qiang MAO Zhi-quan 2014Journal of Integrative Agriculture2014,13,8:8
10Tumor-induced osteomalacia with elevated fibroblast growth factor 23: a case of phosphaturic mesenchymal tumor mixed with connective tissue variants and review of the literature显示文摘Tumor-induced osteomalacia (TIO), or oncogenic osteomalacia (OOM), is a rare acquired paraneoplastic disease characterized by renal phosphate wasting and hypophosphatemia. Recent evidence shows that tumor-overexpressed fibroblast growth factor 23 (FGF23) is responsible for the hypophosphatemia and osteomalacia. The tumors associated with TIO are usually phosphaturic mesenchymal tumor mixed connective tissue variants (PMTMCT). Surgical removal of the responsible tumors is clinically essential for the treatment of TIO. However, identifying the responsible tumors is often difficult. Here, we report a case of a TIO patient with elevated serum FGF23 levels suffering from bone pain and hypophosphatemia for more than three years. A tumor was finally located in first metacarpal bone by octreotide scintigraphy and she was cured by surgery. After complete excision of the tumor, serum FGF23 levels rapidly decreased, dropping to 54.7% of the preoperative level one hour after surgery and eventually to a little below normal. The patient's serum phosphate level rapidly improved and returned to normal level in four days. Accordingly, her clinical symptoms were greatly improved within one month after surgery. There was no sign of tumor recurrence during an 18-month period of follow-up. According to pathology, the tumor was originally diagnosed as 'glomangioma' based upon a biopsy sample, 'proliferative giant cell tumor of tendon sheath' based upon sections of tumor, and finally diagnosed as PMTMCT by consultation one year after surgery. In conclusion, although an extremely rare disease, clinicians and pathologists should be aware of the existence of TIO and PMTMCT, respectively.Fang-Ke Hu Fang Yuan Cheng-Ying Jiang Da-Wei Lv Bei-Bei Mao Qiang Zhang Zeng-Qiang Yuan Yan Wang 2011Chinese Journal of Cancer2011,30,11:8
11In situ construction of porous hierarchical(Ni3-xFex)FeN/Ni heterojunctions toward efficient electrocatalytic oxygen evolution显示文摘As a choke point in water electrolysis,the oxygen evolution reaction(OER)suffers from the severe electrode polarization and large overpotential.Herein,the porous hierarchical hetero-(Nis Fe)FeN/Ni catalysts are in situ constructed for the eficient electrocatalytic OER.X-ray absorption fine structure characterizations reveal the strong Ni-Fe bimetallic interaction in(Niz Fex)FeN/Ni.Theoretical study indicates the heterojunction and bimetallic interaction decrease the free-energy change for the rate-limiting step of the OER and the overpotential thereof.In addition,the high conductivity and porous hierarchical morphology favor the electron transfer,electrolyte access and O2 release.Consequently,the optimized catalyst achieves a low overpotential of 223 mV at 10 mA.cm^-2,a small Tafel slope of 68 mV:dec^-1,and a high stability.The excellent performance of the optimized catalyst is also demonstrated by the overall water electrolysis with a low working voltage and high Faradaic efficiency.Moreover,the correlation between the structure and performance is well established by the experimental characterizations and theoretical calculations,which confirms the origin of the OER activity from the surface metal oxyhydroxide in situ generated upon applying the current.This study suggests a promising approach to the advanced OER electrocatalysts for practical applications by constructing the porous hierarchical metal-compound/metal heterojunctions.Minglei Yan Kun Mao Peixin Cui Chi Chen Jie Zhao Xizhang Wang Lijun Yang Hui Yang Qiang Wu Zheng Hu 2020Nano Research2020,13,2:8
12Advanced Ni-Nx-C single-site catalysts for CO2 electroreduction to CO based on hierarchical carbon nanocages and S-doping显示文摘Metal-nitrogen-carbon materials are promising catalysts for CO2 electroreduction to CO. Herein, by taking the unique hierarchical carbon nanocages as the support, an advanced nickel-nitrogen-carbon single-site catalyst is conveniently prepared by pyrolyzing the mixture of NiCl2 and phenanthroline, which exhibits a Faradaic efficiency plateau of > 87% in a wide potential window of −0.6 – −1.0 V. Further S-doping by adding KSCN into the precursor much enhances the CO specific current density by 68%, up to 37.5 A·g−1 at −0.8 V, along with an improved CO Faradaic efficiency plateau of > 90%. Such an enhancement can be ascribed to the facilitated CO pathway and suppressed hydrogen evolution from thermodynamic viewpoint as well as the increased electroactive surface area and improved charge transfer fromkinetic viewpoint due to the S-doping. This study demonstrates a simple and effective approach to advanced electrocatalysts by synergetic modification of the porous carbon-based support and electronic structure of the active sites.Yiqun Chen Yuejian Yao Yujian Xia Kun Mao Gongao Tang Qiang Wu Lijun Yang Xizhang Wang Xuhui Sun Zheng Hu 2020Nano Research2020,13,10:8

15Destruction of charge ordering phase in La_(0.4)Ca_(0.6)MnO_3 induced by low Cr doping显示文摘Polycrystalline samples of La0.4Cao.6Mn1-xCrxO3 (x = 0.00, 0.02, 0.04, 0.06) were prepared by the solid state reaction method. The influence of Cr3+ substitution for Mn3+ on the magnetic property and charge ordering phase of La0.4Ca0.6MnO3 was studied through the measurements of X-ray diffraction (XRD), magnetization-temperature (M-T) curves and electron spin resonance (ESR) spectra. The experimental results indicate that the mother's body of La0.4Ca0.6MnO3 has very complicated magnetic structure, exhibits charge ordering phase at 258 K, and shows long-range strongly correlated charge ordering-antiferromagnetism (CO-AFM) phase from 175 to 50 K. Spin glass state appears when the temperature decreases to about 41 K. When the Cr substitution amount is x = 0.06, the charge ordering phase of the mother's body is de-stroyed, because the Cr3+ substitution for Mn3+ destroys the spin order of CE-type antiferromagnetism, and thus leads to the melting of charge ordering. It is verified experimentally that the strong coupling between charge order and spin order exists in the charge order system of CE-type antiferromagnetism.PENG Zhensheng YANG Gang WANG Guiying TANG Yonggang GUO Huanyin MAO Qiang 2011Rare Metals2011,30,3:6
16Dynamics of Rodent and Rodent-borne Disease during Construction of the Three Gorges Reservoir from 1997 to 2012显示文摘Objective To investigate the impact of impoundment and active public health interventions on rodent populations and rodent-borne diseases in the Three Gorges reservoir region from 1997 to 2012. Methods Surveillance data from 1997 to 2012 were extracted from the Public Health Surveillance System of The Three Gorges established in 1997. Temporal changes in the incidences of hemorrhagic fever with renal syndrome(HFRS) and leptospirosis, rodent density, pathogen-carrying rates, and their correlations were analyzed. Results The average indoor and outdoor rodent densities decreased overall from 1997 to 2012. The average densities decreased by 47.72%(from 4.38% to 2.29%) and 39.68%(from 4.41% to 2.66%), respectively, after impoundment(2003-2012) compared with before impoundment(1997-2002). The average annual incidence rates of HFRS and leptospirosis were 0.29/100,000 and 0.52/100,000, respectively, and decreased by 85.74%(from 0.68/100,000 to 0.10/100,000) and 95.73%(from 1.47/100,000 to 0.065/100,000), respectively, after impoundment compared with before impoundment. Incidences of HFRS and leptospirosis appear to be positively correlated with rodent density in the reservoir area. Conclusion This study demonstrated that rodent density and incidences of rodent-borne diseases decreased and were maintained at low levels during construction of the Three Gorges dam.

18Ki-67 index,progesterone receptor expression,histologic grade and tumor size in predicting breast cancer recurrence risk:A consecutive cohort study显示文摘Background:The 21-gene recurrence score(RS)assay has been recommended by major guidelines for treatment decision in hormone receptor(HR)-positive early breast cancer(EBC).However,the genomic assay is not accessible and affordable worldwide.Alternatively,an increasing number of studies have shown that traditional immunohistochemistry(IHC)can partially or even completely replace the role of the 21-gene genomic assay.Here,we developed and validated a predictive model(IHC3 model)combining the Ki-67 index,progesterone receptor(PR)expression,histologic grade,and tumor size to predict the recurrence risk of HR-positive EBC.Methods:The data from 389 patients(development set)with HR-positive,human epidermal growth factor receptor 2-negative,lymph node non-metastasized invasive breast cancer were used to construct the IHC3 model based on the Surexam®21-gene RS and the TAILORx clinical trial criteria.An additional 146 patients with the same characteristics constituted the validation set.The predictive accuracy of the IHC3 model was compared with that of Orucevic et al.’s nomogram.Invasive diseasefree survival(IDFS)was analyzed in the IHC3 predictive low-recurrence risk(pLR)group and the predictive high-recurrence risk(pHR)group.The Pearson chi-square test,Fisher exact test,and log-rank test were used for analysis.Results:The pLR and pHR group could be easily stratified using the decision tree model without network dependence.The accuracies of the IHC3 model were 86.1%in the development set and 87.7%in the validation set.The predictive accuracy of the IHC3 model and Orucevic et al.’s nomogram for the whole cohort was 86.5%and 86.9%,respectively.After a 52-month of median follow-up,a significant difference was found in IDFS between of the IHC3 pLR and the pHR groups(P=0.001)but not in the IDFS between the low-and high-recurrence risk groups according to the Surexam®21-gene RS and the TAILORx clinical trial criteria(P=0.556)or 21-gene binary RS group(P=0.511).Conclusions:The proposed IHC3 model could reliably predict low and high recurrence risks in most HR-positive EBC patients.This easy-to-use predictive model may be a reliable replacement for the 21-gene genomic assay in patients with EBC who have no access to or cannot afford the 21-gene genomic assay.Yanna Zhang Yidong Zhou Feng Mao Ru Yao Qiang Sun 2020Cancer Communications2020,40,4:5
