1Therapeutic effect of acupuncture and massage for shoulder-hand syndrome in hemiplegia patients:a clinical two-center randomized controlled trial显示文摘OBJECTIVE:To evaluate the therapeutic effects of acupuncture and massage for shoulder-hand syndrome in hemiplegia patients.METHODS:One hundred and twenty hemiplegia patients with stage I shoulder-hand syndrome were randomly divided into a group treated with standardized electric acupuncture and massage,and a group treated with rehabilitation therapy for 6 weeks.The primary indices evaluated were pain on passive movement of the shoulder using the numeric pain rating scale(NPRS),and the number of patients with shoulder-hand syndrome at Steinbrocker stage II or III after treatment.The secondary indices were Fugl-Meyer evaluation of functional movement of the upper limb and hand using the modified rankin scale(MRS).RESULTS:At post-treatment evaluation and a 12-week follow-up visit,NPRS score,number of patients with stage II or III shoulder-hand syndrome,and MRS score were all improved in the acupuncture-massage group compared with the rehabilitation group(P<0.05).On Fugl-Meyer evaluation,functional movement of the upper limb was also improved in the acupuncture-massage group compared with the rehabilitation group(P<0.05).CONCLUSION:Standardized acupuncture-massage therapy may have curative effects on shoulder-hand syndrome in hemiplegia patients.Ning Li Fengwei Tian Chengwei Wang Pengming Yu Xi Zhou Qian Wen Xiulan Qiao Lu Huang 2012Journal of Traditional Chinese Medicine2012,32,3:25
2Clinical curative effect of electric acupuncture on acute cerebral infarction:a randomized controlled multicenter trial显示文摘OBJECTIVE: To examine whether electric acupuncture can improve the daily life of patients with ischemic cerebral apoplexy at acute stage.METHODS: A stratified-block randomized controlled multicenter trial was designed for this study.Totally 340 patients with acute ischemic cerebral apoplexy were randomly divided into an electric acupuncture group and a control group. In the electric acupuncture group, 170 patients were treated with electric acupuncture and routine therapy, and170 patients in the control group with routine therapy alone. Major indexes for judging curative effect were Barthel index at 3- and 6- months follow-up visits and number of re-hospitalized patients. Mi-nor indexes for judging curative effect were change in the score for nervous dysfunction at 4and 12 weeks follow-up visits and number of patients persisting in rehabilitation treatment with acupuncture during follow-up visit.RESULTS: Baseline data at the time of case selection between the two groups were similar. The odds ratio(OR) was 0.92, and the 95% confidence interval(CI) was 0.49-1.73 in disabled rate and 0.73 and 0.51-1.05 in the number of re-hospitalized patients in the electric acupuncture group at 6-month follow up visit compared with the control group.There was no difference in the score for nervous dysfunction at the end of 12-week follow-up visit between the two groups. The score for nervous dysfunction at the end of 4-week treatment in the electric acupuncture group was significantly higher than that in the control group(P<0.05). The number of patients discharged from hospital who persisted in rehabilitation treatment with acupuncture in the acupuncture group was significantly higher than that in the control group.CONCLUSION: Using electric acupuncture to treat patients with acute ischemic cerebral apoplexy can effectively improve the nervous dysfunction scores after 4-week treatment and their ability to deal with daily life after 6-month follow-up visit. Systematic treatment with acupuncture may also reduce the number of patients with secondary apoplexy.Chengwei Wang Zhongchao Wu Ning Li Yu Zhao Fengwei Tian Xi Zhou Zhuxing Wang 2014Journal of Traditional Chinese Medicine2014,34,6:22
3The Popularization and Application of Cold Storage Red Blood Cells or Whole Blood at -80 ℃ of the Rh(D) Negative Patients in Surgical Operation显示文摘Summary: The efficiency of cold storage red blood cells (CSRBC) or whole blood at -80 ℃ used in 27 Rh(D) negative patients during surgical operation was reported. The Rh(D) negative patients received the transfusion of CSRBC or whole blood stored at -80 ℃ for 180 to 360 days. The changes in the indexes, such as blood TB, DB, K +, Na +, BUN, Cr, urine protein (URPO), UOB, Hb, HCT, serum total protein, relative to hemolytic reaction and blood volume before and after transfusion were observed. The results showed that after transfusion of CSRBC or whole blood 27 cases were negative for urine protein and UOB, and the levels of BUN and Cr were normal (P>0.05). Blood TB, DB, Hb, and HCT were increased, while pH, blood K + and blood Na + was normal with the difference being not significant before and after operation (P>0.05). Plasma protein was decreased, but there was no significant difference before and after operation (P>0.05). It was suggested that CSRBC or whole blood at -80 ℃ could be safely infused to the Rh(D) negative patients without side effects during the surgical operation.YU Zhongqing(余忠清) HU Lihua(胡丽华) Han Min(韩敏) RAO Shenzong(饶神宗) LUO Chengwei(罗成伟) 2002Journal of Huazhong University of Science and Technology(Medical Sciences)2002,22,2:3
4Configuration and operation combined optimization for EV battery swapping station considering PV consumption bundling显示文摘Integration of electric vehicles(EVs),demand response and renewable energy will bring multiple opportunities for low carbon power system.A promising integration will be EV battery swapping station(BSS)bundled with PV(photovoltaic)power.Optimizing the configuration and operation of BSS is the key problem to maximize benefit of this integration.The main objective of this paper is to solve infrastructure configuration of BSS.The principle challenge of such an objective is to enhance the swapping ability and save corresponding investment and operation cost under uncertainties of PV generation and swapping demand.Consequently this paper mainly concentrates on combining operation optimization with optimal investment strategies for BSS considering multiscenarios PV power generation and swapping demand.A stochastic programming model is developed by using state flow method to express different states of batteries and its objective is to maximize the station’s net profit.The model is formulated as a mixed-integer linear program to guarantee the efficiency and stability of the optimization.Case studies validate the effectiveness of the proposed approach and demonstrate that ignoring the uncertainties of PV generation and swapping demand may lead to an inappropriate batteries,chargers and swapping robots configuration for BSS.Yu Cheng Chengwei Zhang 2017Protection and Control of Modern Power Systems2017,2,1:2
5Clay nanosheet-mediated delivery of recombinant plasmids expressing artificial miRNAs via leaf spray to prevent infection by plant DNA viruses显示文摘Whitefly-transmitted begomoviruses are economically important plant pathogens that cause severe problems in many crop plants,such as tomato,papaya,cotton,and tobacco.Tomato yellow leaf curl virus(TYLCV)is a typical monopartite begomovirus that has been extensively studied,but methods that can efficiently control begomoviruses are still scarce.In this study,we combined artificial microRNA(amiRNA)-mediated silencing technology and clay nanosheetmediated delivery by spraying and developed a method for efficiently preventing TYLCV infection in tomato plants.We designed three amiRNAs that target different regions of TYLCV to silence virus-produced transcripts.Three plant expression vectors expressing pre-amiRNAs were constructed,and recombinant plasmid DNAs(pDNAs)were loaded onto nontoxic and degradable layered double hydroxide(LDH)clay nanosheets.LDH nanosheets containing multiple pDNAs were sprayed onto plant leaves.We found that the designed amiRNAs were significantly accumulated in leaves 7 days after spraying,while the pDNAs were sustainably detected for 35 days after the spray,suggesting that the LDH nanosheets released pDNAs in a sustained manner,protected pDNAs from degradation and efficiently delivered pDNAs into plant cells.Importantly,when the LDH nanosheets coated with pDNAs were sprayed onto plants infected by TYLCV,both the disease severity and TYLCV viral concentration in sprayed plants were significantly decreased during the 35 days,while the levels of H_(2)O_(2) were significantly increased in those plants.Taken together,these results indicate that LDH nanosheets loaded with pDNAs expressing amiRNAs can be a sustainable and promising tool for begomovirus control.Qili Liu Yanpeng Li Kedong Xu Dongxiao Li Haiyan Hu Feng Zhou Puwen Song Yongang Yu Qichao Wei Qian Liu Weipeng Wang Ruifang Bu Haili Sun Xiaohui Wang Jianjun Hao Honglian Li Chengwei Li 2020Horticulture Research2020,7,1:1

15Bound lipase:an important form of lipase in rice bran (Oryza sativa)显示文摘Rice bran residue possessed a steady lipase activity((26.68 ± 3.69)%)after its endogenous lipase was extracted continuously by phosphate buffer solution(PBS)for 24 h. T herefore, the aim of this research was to explore whether there exist any bound lipases in rice bran(Oryza sativa). Three physical treatments(grinding, homogenizing and ultrasound crush)and 6 enzymatic treatments(cellulase, hemicellulase, pectinase, complex cellulase, glucoamylase and α-amylase)were applied to rice bran in order to investigate this bound lipase. The relative catalytic activities of extraction supernatant and residue for pectinase group were(437.63 ± 22.54)% and(159.26 ± 2.12)%, respectively, which were significantly higher(P < 0.05)than other groups. This phenomenon demonstrated that lipase was the most likely to combine with pectin. Molecular simulation proved that pectin could combine with two rice bran lipases(lipase 315 and lipase 308)and cover the catalytic centers so as to prevent the lipases from encountering the substrate and inhibiting their catalytic activities. During combination, pectin could make the lipases more compact and reduce the solvent accessible surface area of lipases, which would make the lipases inactive to molecular interaction. In summary, part of rice bran lipase was proved to exist in bound form and combined with the pectin.Chengwei Yu Bin Peng Ting Luo Zeyuan Deng 2023Food Science and Human Wellness2023,12,5:0
16Natural siderite derivatives activated peroxydisulfate toward oxidation of organic contaminant: A green soil remediation strategy显示文摘Natural siderite(FeCO_(3)),simulated synthetic siderite and nZVI/FeCO_(3) composite were used as green and easily available iron-based catalysts in peroxydisulfate activation for remediating 2-chlorophenol as the target contaminant and this technique can effectively degrade organic pollutants in the soil.The key reaction parameters such as catalysts dosage,oxidant concentration and pH,were investigated to evaluate the catalytic performance of different materials in catalytic systems.The buffering property of natural soil conduced satisfactory degradation performance in a wide pH range(3-10).Both the main non-radical of ^(1)O_(2) and free radicals of SO_(4)^(-) and OH·were evidenced by quenching experiment and electron paramagnetic resonance.The reduction of nZVI on FFC surface not only has the advantage for electronic transfer to promote the circulation of Fe(Ⅲ)to Fe(Ⅱ),but also can directly dechlorinate.Furthermore,the intermediates were comprehensively analyzed by GC-MS and a potential removal mechanism of three oxidant system for 2-CP soil degradation was obtained.Briefly,this research provides a new perspective for organic contaminate soil treatment using natural siderite or simulated synthetic siderite as efficient and environmental catalytic material.Chengwei Zhong Yinying Jiang Quanfeng Liu Xiaoshuang Sun Jiang Yu 2023Journal of Environmental Sciences2023,,5:0

19Flexoelectricity-enhanced photovoltaic effect in trapezoid-shaped NaNbO_(3)nanotube array composites显示文摘In this work,we successfully prepared vertically aligned NaNbO_(3)nanotube(NN-NT)with trapezoidal shapes,in which the orthorhombic and monoclinic phases coexisted.According to the structure analysis,the NN-NT/epoxy composite film had excellent flexoelectric properties due to the lattice distortion caused by defects and irregular shape.The flexoelectric effect is the greatest in the vertical direction in the flexible NN-NT/epoxy composite film,and the flexoelectric coefficient()is 2.77×10^(−8)C·m^(−1),which is approximately 5-fold higher than that of the pure epoxy film.The photovoltaic current of the NN-NT/epoxy composite film increased from 39.9 to 71.8 nA·cm^(−2)in the direction of spontaneous polarization when the sample was bent upward due to the flexoelectricity-enhanced photovoltaic(FPV)effect.The flexoelectric effect of the NN-NT/epoxy composite film could modulate the photovoltaic response by increasing it by 80%or reducing it to 65%of the original value.This work provides a new idea for further exploration in efficient and lossless ferroelectric memory devices.Fang Yu Junyuan Tian Fengying Jiang Yunjie Liu Chaohai Li Chengwei Wang Zhong Lin Wang Kailiang Ren 2023Nano Research2023,16,9:0
20NDRG1 promotes endothelial dysfunction and hypoxia-induced pulmonary hypertension by targeting TAF15显示文摘Background:Pulmonary hypertension(PH)represents a threatening pathophysiologic state that can be induced by chronic hypoxia and is characterized by extensive vascular remodeling.However,the mechanism underlying hypoxia-induced vascular remodeling is not fully elucidated.Methods and Results:By using quantitative polymerase chain reactions,western blotting,and immunohistochemistry,we demon-strate that the expression of N-myc downstream regulated gene-1(NDRG1)is markedly increased in hypoxia-stimulated endothelial cells in a time-dependent manner as well as in human and rat endothelium lesions.To determine the role of NDRG1 in endothelial dysfunction,we performed loss-of-function studies using NDRG1 short hairpin RNAs and NDRG1 over-expression plasmids.In vitro,silencing NDRG1 attenuated proliferation,migration,and tube formation of human pulmonary artery endothelial cells(HPAECs)un-der hypoxia,while NDRG1 over-expression promoted these behaviors of HPAECs.Mechanistically,NDRG1 can directly interact with TATA-box binding protein associated factor 15(TAF15)and promote its nuclear localization.Knockdown of TAF15 abrogated the effect of NDRG1 on the proliferation,migration and tube formation capacity of HPAECs.Bioinformatics studies found that TAF15 was involved in regulating PI3K-Akt,p53,and hypoxia-inducible factor 1(HIF-1)signaling pathways,which have been proved to be PH-related pathways.In addition,vascular remodeling and right ventricular hypertrophy induced by hypoxia were markedly alleviated in NDRG1 knock-down rats compared with their wild-type littermates.Conclusions:Taken together,our results indicate that hypoxia-induced upregulation of NDRG1 contributes to endothelial dysfunction through targeting TAF15,which ultimately contributes to the development of hypoxia-induced PH.Chengwei Li Junzhu Lv Gulinuer Wumaier Yu Zhao Liang Dong Yuzhen Zeng Ning Zhu Xiujuan Zhang Jing Wang Jingwen Xia Shengqing Li 2023Precision Clinical Medicine2023,6,4:0
