| 1 | Rule-based Fault Diagnosis of Hall Sensors and Fault-tolerant Control of PMSM显示文摘Hall sensor is widely used for estimating rotor phase of permanent magnet synchronous motor(PMSM). And rotor position is an essential parameter of PMSM control algorithm, hence it is very dangerous if Hall senor faults occur. But there is scarcely any research focusing on fault diagnosis and fault-tolerant control of Hall sensor used in PMSM. From this standpoint, the Hall sensor faults which may occur during the PMSM operating are theoretically analyzed. According to the analysis results, the fault diagnosis algorithm of Hall sensor, which is based on three rules, is proposed to classify the fault phenomena accurately. The rotor phase estimation algorithms, based on one or two Hall sensor(s), are initialized to engender the fault-tolerant control algorithm. The fault diagnosis algorithm can detect 60 Hall fault phenomena in total as well as all detections can be fulfilled in 1/138 rotor rotation period. The fault-tolerant control algorithm can achieve a smooth torque production which means the same control effect as normal control mode (with three Hall sensors). Finally, the PMSM bench test verifies the accuracy and rapidity of fault diagnosis and fault-tolerant control strategies. The fault diagnosis algorithm can detect all Hall sensor faults promptly and fault-tolerant control algorithm allows the PMSM to face failure conditions of one or two Hall sensor(s). In addition, the transitions between health-control and fault-tolerant control conditions are smooth without any additional noise and harshness. Proposed algorithms can deal with the Hall sensor faults of PMSM in real applications, and can be provided to realize the fault diagnosis and fault-tolerant control of PMSM. | SONG Ziyou LI Jianqiu OUYANG Minggao GU Jing FENG Xuning LU Dongbin | 2013 | Chinese Journal of Mechanical Engineering2013，26，4： | 12 |
| 2 | Internal short circuit evaluation and corresponding failure mode analysis for lithium-ion batteries显示文摘Internal short circuit(ISC)is the major failure problem for the safe application of lithium-ion batteries,especially for the batteries with high energy density.However,how to quantify the hazard aroused by the ISC,and what kinds of ISC will lead to thermal runaway are still unclear.This paper investigates the thermal-electrical coupled behaviors of ISC,using batteries with Li(Ni_(1/3)CO_(1/3)Mn_(1/3))O_(2) cathode and composite separator.The electrochemical impedance spectroscopy of customized battery that has no LiPF6 salt is utilized to standardize the resistance of ISC.Furthermore,this paper compares the thermal-electrical coupled behaviors of the above four types of ISC at different states-of-charge.There is an area expansion phenomenon for the aluminum-anode type of ISC.The expansion effect of the failure area directly links to the melting and collapse of separator,and plays an important role in further evolution of thermal runaway.This work provides guidance to the development of the ISC models,detection algorithms,and correlated countermeasures. | Lishuo Liu Xuning Feng Christiane Rahe Weihan Li Languang Lu Xiangming He Dirk Uwe Sauer Minggao Ouyang | 2021 | Journal of Energy Chemistry2021，30，10： | 5 |
| 3 | Gleaning insights from German energy transition and large-scale underground energy storage for China’s carbon neutrality显示文摘The global energy transition is a widespread phenomenon that requires international exchange of experiences and mutual learning.Germany’s success in its first phase of energy transition can be attributed to its adoption of smart energy technology and implementation of electricity futures and spot marketization,which enabled the achievement of multiple energy spatial–temporal complementarities and overall grid balance through energy conversion and reconversion technologies.While China can draw from Germany’s experience to inform its own energy transition efforts,its 11-fold higher annual electricity consumption requires a distinct approach.We recommend a clean energy system based on smart sector coupling(ENSYSCO)as a suitable pathway for achieving sustainable energy in China,given that renewable energy is expected to guarantee 85%of China’s energy production by 2060,requiring significant future electricity storage capacity.Nonetheless,renewable energy storage remains a significant challenge.We propose four large-scale underground energy storage methods based on ENSYSCO to address this challenge,while considering China’s national conditions.These proposals have culminated in pilot projects for large-scale underground energy storage in China,which we believe is a necessary choice for achieving carbon neutrality in China and enabling efficient and safe grid integration of renewable energy within the framework of ENSYSCO. | Yachen Xie Xuning Wu Zhengmeng Hou Zaoyuan Li Jiashun Luo Christian Truitt Lüddeke Liangchao Huang Lin Wu Jianxing Liao | 2023 | International Journal of Mining Science and Technology2023，33，5： | 4 |
| 4 | A Comparative Study of Charging Voltage Curve Analysis and State of Health Estimation of Lithium-ion Batteries in Electric Vehicle显示文摘Lithium-ion(Li-ion)cells degrade after repeated cycling and the cell capacity fades while its resistance increases.Degra-dation of Li-ion cells is caused by a variety of physical and chemical mechanisms and it is strongly influenced by factors including the electrode materials used,the working conditions and the battery temperature.At present,charging voltage curve analysis methods are widely used in studies of battery characteristics and the constant current charging voltage curves can be used to analyze battery aging mechanisms and estimate a battery’s state of health(SOH)via methods such as incremental capacity(IC)analysis.In this paper,a method to fit and analyze the charging voltage curve based on a neural network is proposed and is compared to the existing point counting method and the polynomial curve fitting method.The neuron parameters of the trained neural network model are used to analyze the battery capacity relative to the phase change reactions that occur inside the batteries.This method is suitable for different types of batteries and could be used in battery management systems for online battery modeling,analysis and diagnosis. | Xuebing Han Xuning Feng Minggao Ouyang Languang Lu Jianqiu Li Yuejiu Zheng Zhe Li | 2019 | Automotive Innovation2019，2，4： | 3 |

| 6 | Topotactically constructed nickel-iron(oxy)hydroxide with abundant in-situ produced high-valent iron species for efficient water oxidation显示文摘The low efficiency of oxygen evolution reaction(OER) is regarded as one of the major roadblocks for metal-air batteries and water electrolysis.Herein,a high-performance OER catalyst of NiFe_(0.2)(oxy)hydroxide(NiFe_(0.2)-O_(x)H_(y)) was developed through topotactic transformation of a Prussian blue analogue in an alkaline solution,which exhibits a low overpotential of only 263 mV to reach a current density of 10 mA cm^(-2) and a small Tafel slope of 35 mV dec-1.Ex-situ/operando Raman spectroscopy results indicated that the phase structure of NiFe_(0.2)-O_(x)H_(y) was irreversibly transformed from the type of α-Ni(OH)_(2) to γ-NiOOH with applying an anodic potential,while ex-situ/operando 57Fe Mossbauer spectroscopic studies evidenced the in-situ production of abundant high-valent iron species under OER conditions,which effectively promoted the OER catalysis.Our work elucidates that the amount of high-valent iron species in-situ produced in the NiFe(oxy)hydroxide has a positive correlation with its water oxidation reaction performance,which further deepens the understanding of the mechanism of NiFe-based electrocatalysts. | Zhichong Kuang Song Liu Xuning Li Meng Wang Xinyi Ren Jie Ding Rile Ge Wenhui Zhou Alexandre IRykov Moulay TSougrati Pierre-Emmanuel Lippens Yanqiang Huang Junhu Wang | 2021 | Journal of Energy Chemistry2021，30，6： | 2 |

| 8 | Thermal Runaway of Lithium-Ion Batteries Employing Flame-Retardant Fluorinated Electrolytes显示文摘Fluorinated electrolytes possess good antioxidant capacity that provides high compatibility to high-voltage cathode and flame retardance;thus,they are considered as a promising solution for advanced lithium-ion batteries carrying both high-energy density and high safety.Moreover,the fluorinated electrolytes are widely used to form stable electrolyte interphase,due to their chemical reactivity with lithiated graphite or lithium.However,the influence of this reactivity on the thermal safety of batteries is seldom discussed.Herein,we demonstrate that the flame-retardant fluorinated electrolytes help to reduce the flammability,while the lithium-ion batteries with flame-retardant fluorinated electrolytes still undergo thermal runaway and disclose their different thermal runaway pathway from that of battery with conventional electrolyte.The reduction in fluorinated components(e.g.,LiPF 6 and fluoroethylene carbonate(FEC))by fully lithiated graphite accounts for a significant heat release during battery thermal runaway.The 13%of total heat is sufficient to trigger the chain reactions during battery thermal runaway.This study deepens the understanding of the thermal runaway mechanism of lithium-ion batteries employing flame-retardant fluorinated electrolytes,providing guidance on the concept of electrolyte design for safer lithium-ion batteries. | Junxian Hou Li Wang Xuning Feng Junpei Terada Languang Lu Shigeaki Yamazaki Anyu Su Yoshiko Kuwajima Yongjiang Chen Tomoya Hidaka Xiangming He Hewu Wang Minggao Ouyang | 2023 | Energy & Environmental Materials2023，6，1： | 1 |
| 9 | A novel transgenic mouse model of Chinese CharcotMarie-Tooth disease type 2L显示文摘We previously found that the K141N mutation in heat shock protein B8(HSPB8) was responsible for Charcot-Marie-Tooth disease type 2L in a large Chinese family.The objective of the present study was to generate a transgenic mouse model bearing the K141N mutation in the human HSPB8 gene,and to determine whether this K141NHSPB8 transgenic mouse model would manifest the clinical phenotype of Charcot-Marie-Tooth disease type 2L,and consequently be suitable for use in studies of disease pathogenesis.Transgenic mice overexpressing K141NHSPB8 were generated using K141N mutant HSPB8 cDNA cloned into a pCAGGS plasmid driven by a human cytomegalovirus expression system.PCR and western blot analysis confirmed integration of the K141NHSPB8 gene and widespread expression in tissues of the transgenic mice.The K141NHSPB8 transgenic mice exhibited decreased muscle strength in the hind limbs and impaired motor coordination,but no obvious sensory disturbance at 6 months of age by behavioral assessment.Electrophysiological analysis showed that the compound motor action potential amplitude in the sciatic nerve was significantly decreased,but motor nerve conduction velocity remained normal at 6 months of age.Pathological analysis of the sciatic nerve showed reduced myelinated fiber density,notable axonal edema and vacuolar degeneration in K141NHSPB8 transgenic mice,suggesting axonal involvement in the peripheral nerve damage in these animals.These findings indicate that the K141NHSPB8 transgenic mouse successfully models Charcot-Marie-Tooth disease type 2L and can be used to study the pathogenesis of the disease. | Ruxu Zhang Fufeng Zhang Xiaobo Li Shunxiang Huang Xiaohong Zi Ting Liu Sanmei Liu Xuning Li Kun Xia Qian Pan Beisha Tang | 2014 | Neural Regeneration Research2014，9，4： | 1 |
| 10 | In-depth investigation of the exothermic reactions between lithiated graphite and electrolyte in lithium-ion battery显示文摘Thermal runaway is a critical issue for the large application of lithium-ion batteries.Exothermic reactions between lithiated graphite and electrolyte play a crucial role in the thermal runaway of lithium-ion batteries.However,the role of each component in the electrolyte during the exothermic reactions with lithiated graphite has not been fully understood.In this paper,the exothermic reactions between lithiated graphite and electrolyte of lithium-ion battery are investigated through differential scanning calorimetry(DSC) and evolved gas analysis.The lithiated graphite in the presence of electrolyte exhibit three exothermic peaks during DSC test.The reactions between lithiated graphite and LiPF_(6) and ethylene carbonate are found to be responsible for the first two exothermic peaks,while the third exothermic peak is attributed to the reaction between lithiated graphite and binder.In contrast,diethylene carbonate and ethyl methyl carbonate contribute little to the total heat generation of graphite-electrolyte reactions.The reaction mechanism between lithiated graphite and electrolyte,including the major reaction equations and gas products,are summarized.Finally,DSC tests on samples with various amounts of electrolyte are performed to clarify the quantitative relationship between lithiated graphite and electrolyte during the exothermic reactions.2.5 mg of lithiated graphite (Li_(0.8627)C_(6)) can fully react with around 7.2 mg electrolyte,releasing a heat generation of 2491 J g^(-1).The results presented in this study can provide useful guidance for the safety improvement of lithium-ion batteries. | Yuejiu Zheng Zhihe Shi Dongsheng Ren Jie Chen Xiang Liu Xuning Feng Li Wang Xuebing Han Languang Lu Xiangming He Minggao Ouyang | 2022 | Journal of Energy Chemistry2022，31，6： | 1 |
| 11 | Electrolyte induced synergistic construction of cathode electrolyte interphase and capture of reactive free radicals for safer high energy density lithium-ion battery显示文摘As the energy density of battery increases rapidly,lithium-ion batteries(LIBs)are facing serious safety issue with thermal runaway,which largely limits the large-scale applications of high-energy-density LIBs.It is generally agreed that the chemical crosstalk between the cathode and anode leads to thermal runaway of LIBs.Herein,a multifunctional high safety electrolyte is designed with synergistic construction of cathode electrolyte interphase and capture of reactive free radicals to limit the intrinsic pathway of thermal runaway.The cathode electrolyte interphase not only resists the gas attack from the anode but suppresses the parasitic side reactions induced by electrolyte.And the function of free radical capture has the ability of reducing heat release from thermal runaway of battery.The dual strategy improves the intrinsic safety of battery prominently that the triggering temperature of thermal runaway is increased by 24.4℃and the maximum temperature is reduced by 177.7℃.Simultaneously,the thermal runaway propagation in module can be self-quenched.Moreover,the electrolyte design balances the trade-off of electrochemical and safety performance of high-energy batteries.The capacity retention of LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)|graphite pouch cell has been significantly increased from 53.85%to 97.05%with higher coulombic efficiency of 99.94%at operating voltage extended up to 4.5 V for 200 cycles.Therefore,this work suggests a feasible strategy to mitigate the safety risk of high-energy-density LIBs without sacrificing electrochemical performances. | Mengfei Ding Xuning Feng Yong Peng Jing Jing Tong Bowen Hou Yalan Xing Weifeng Zhang Li Wang Yu Wu Jiabin Lv Chunyan Luo Dejun Xiong Shichao Zhang Minggao Ouyang | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
| 12 | Experimental Research about Denitrification by Box Filler Enhancing MBR Process显示文摘[Objective]The research aimed to study removal effects of the organic matter and N by box filler enhancing MBR process.[Method]By adding box filler into reaction pool of the MBR to treat domestic sewage,removal effects of the organic matter and N by box filler enhancing MBR process were studied.[Result]COD means in effluent were respectively 26.8 and 24.7 mg /L without and with adding filler.Average removal rates of the NH 3-N were respectively 98.44% and 96.37% with and without dosing filler,while average removal rates of the TN were 24.03% and 16.43%,respectively.COD and NH 3-N concentrations in effluent were lower than Level-one A criteria of Discharge Standard of the Pollutant for Municipal Wastewater Treatment Plant(GB18918-2002).NO 3-N was main existence form of the TN in effluent and occupied 98.06%,while NH 3 N and NO 2-N only accounted for 1.22% and 0.72%.Further suggestion for denitrification study was as below.Firstly,the proportion of box filler on volume of the reaction cell should increase to 4%-5%.Secondly,single smaller filler with larger amount of internal fiber ought to be replaced.Thirdly,aeration amount needed to be decreased to right value,making that DO of the MBR reaction cell reduced to 1.5-3.0 mg /L.[Conclusion] The research provided theoretical basis for future engineering practice. | Xuning Li Tingquan Pei Huan Liu Zhenye Zhao Liyong Mei | 2013 | Meteorological and Environmental Research2013，4，1： | 0 |
| 13 | Mitigating thermal runaway hazard of high-energy lithium-ion batteries by poison agent显示文摘Lithium-ion batteries with high-energy density are extensively commercialized in long-range electric vehicles. However, they are poor in thermal stability and pose fire or explosion, which has attracted the global attention. This study describes a new route to mitigate the battery thermal runaway(TR) hazard by poison agents. First, the self-destructive cell is built using the embedded poison layer. Then, the poisoning mechanism and paths are experimentally investigated at the material, electrode, and cell levels. Finally, the proposed route is verified by TR tests. The results show the TR hazard can be significantly reduced in the self-destructive cell based on a new reaction sequence regulation. Specifically, the maximum temperature of the self-destructive cell is more than 300℃ lower than that of the normal cell during TR. The drop in maximum temperature can reduce total heat release and the probability of TR propagation in the battery system, significantly improving battery safety. | Xin Lai Zheng Meng Fangnan Zhang Yong Peng Weifeng Zhang Lei Sun Li Wang Fei Gao Jie Sheng Shufa Su Yuejiu Zheng Xuning Feng | 2023 | Journal of Energy Chemistry2023，，8： | 0 |
| 14 | Organic Passivation of Deep Defects in Cu(In,Ga)Se_(2) Film for Geometry-Simplified Compound Solar Cells显示文摘Diverse defects in copper indium gallium diselenide solar cells cause nonradiative recombination losses and impair device performance.Here,an organic passivation scheme for surface and grain boundary defects is reported,which employs an organic passivation agent to infiltrate the copper indium gallium diselenide thin films.A transparent conductive passivating(TCP)film is then developed by incorporating metal nanowires into the organic polymer and used in solar cells.The TCP films have a transmittance of more than 90%in the visible and nearinfrared spectra and a sheet resistance of~10.5Ω/sq.This leads to improvements in the open-circuit voltage and the efficiency of the organic passivated solar cells compared with control cells and paves the way for novel approaches to copper indium gallium diselenide defect passivation and possibly other compound solar cells. | Jingwei Chen Xuan Chang Jianxin Guo Qing Gao Xuning Zhang Chenxu Liu Xueliang Yang Xin Zhou Bingbing Chen Feng Li Jianming Wang Xiaobing Yan Dengyuan Song Han Li Benjamin S.Flavel Shufang Wang Jianhui Chen | 2023 | Research2023，，4： | 0 |
| 15 | Molecular dispersion enhances photovoltaic efficiency and thermal stability in quasi-bilayer organic solar cells显示文摘In comparison to widely adopted bulk heterojunction(BHJ)structures for organic solar cells(OSC),exploiting the sequential deposition to form planar heterojunction(PHJ)structures enables to realize the favorable vertical phase separation to facilitate charge extraction and reduce charge recombination in OSCs.However,effective tunings on the power conversion efficiency(PCE)in PHJ-OSCs are still restrained by the currently available methods.Based on a polymeric donor PBDBT-2 F(PBDBT=Poly[[4,8-bis[5-(2-ethylhexyl)-4-fluoro-2-thienyl]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl]-2,5-thiophenediyl[5,7-bis(2-ethylhexyl)-4,8-dioxo-4 H,8 H-benzo[1,2-c:4,5-c′]dithiophene-1,3-diyl]-2,5-thiophenediyl])and a non-fullerene(NF)acceptor Y6,we proposed a strategy to improve the properties of photovoltaic performances in PHJ-based OSCs through dilute dispersions of the PBDBT-2 F donor into the acceptor-dominant phase with the sequential film deposition.With the control of donor dispersions,the charge transport balance in the PHJ-OSCs is improved,leading to the expedited photocarrier sweep-out with reduced bimolecular charge recombination.As a result,a PCE of 15.4%is achieved in the PHJ-OSCs.Importantly,the PHJ solar cells with donor dispersions exhibit better thermal stability than corresponding BHJ devices,which is related to the better film morphology robustness and less affected charge sweep-out during the thermal aging. | Xuning Zhang Yanxun Li Dongyang Zhang Guangbao Wu Hong Zhang Jiyu Zhou Xing Li Saud-uz-Zafar Jianqi Zhang Zhixiang Wei Huiqiong Zhou Yuan Zhang | 2021 | Science China Chemistry2021，64，1： | 0 |
| 16 | Thermal runaway propagation behavior of the Cell-to-Pack battery system显示文摘Structurally compact battery packs significantly improve the driving range of electric vehicles.Technologies like Cell-to-Pack increase energy density by 15%-20%.However,the safety implications of multiple tightly-packed battery cells still require in-depth research.This paper studies thermal runaway propagation behavior in a Cell-to-Pack system and assesses propagation speed relative to other systems.The investigation includes temperature response,extent of battery damage,pack structure deformation,chemical analysis of debris,and other considerations.Results suggest three typical patterns for the thermal runaway propagation process:ordered,disordered,and synchronous.The synchronous propagation pattern displayed the most severe damage,indicating energy release is the largest under the synchronous pattern.This study identifies battery deformation patterns,chemical characteristics of debris,and other observed factors that can both be applied to identify the cause of thermal runaway during accident investigations and help promote safer designs of large battery packs used in large-scale electric energy storage systems. | Huaibin Wang Qinzheng Wang Zhenyang Zhao Changyong Jin Chengshan Xu Wensheng Huang Zhuchen Yuan Shuyu Wang Yang Li Yanhong Zhao Junli Sun Xuning Feng | 2023 | Journal of Energy Chemistry2023，，9： | 0 |
| 17 | Structural reconstruction of Sn-based metal-organic frameworks for efficient electrochemical CO_(2) reduction to formate显示文摘MOF-based materials have been widely explored in electrochemical CO_(2)reduction reactions for the production of valuable chemicals.Understanding the reconstruction of those catalysts under working conditions is crucial for the identification of active sites and clarification of reaction mechanism.Herein,a series of six N coordinated Sn-based metal-organic frameworks(Sn-N6-MOFs)are newly developed for electrochemical CO_(2)reduction(CO_(2)RR).2%Sn-N6-MOF achieves the optimal catalytic performance with a formate Faradaic efficiency of~85%and a current density of 23 mA·cm^(-2) at-1.23 V vs.RHE.In-situ Raman results combined with ex-situ ^(119)Sn Mössbauer measurements reveal the structural reconstruction of Sn-N6-MOFs during CO_(2)RR,generating tin nanoclusters as the real active sites for CO_(2)electroreduction to HCOOH. | Yachen Deng Shifu Wang Yanqiang Huang Xuning Li | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 0 |
| 18 | Parameter-independent error correction for potential measurements by reference electrode in lithium-ion batteries显示文摘The safety monitoring of lithium-ion batteries(LIBs) is of great significance for realizing all-climate and full-lifespan battery management. In-situ measurement of anode potential with implanted reference electrodes(REs) has proven to be effective to monitor and avoid the occurrence of severe side reactions like Li plating to ensure the safe and fast charging. However, the intrinsic measurement errors caused by local blocking effects, which also can be referred to as potential artefacts, are seldom taken into consideration in existing studies, yet they highly dominate the correctness of conclusions inferred from REs. In this study, aiming at exploring the physical origin of the measurement errors and ensure reliable potential monitoring, electrochemical and post-mortem tests are conducted using commercial pouch cells with implanted REs. Corresponding electrochemical model which describes the blocking effects, is established to validate the abnormal absence of lithium plating that predicted by measured anode potentials under various charging rates. Theoretical derivation is further presented to explain the error sources, which can be attributed to increased local liquid potential of the RE position. Most importantly, with the guidance of error analysis, a novel parameter-independent error correction method for RE measurements is proposed for the first time, which is proven to be adequate to estimate the real anode potentials and deduce the critical C-rate of Li plating with extra safety margin. After error correction, the resulting critical C-rates are all within the range of 0.55 ± 0.03 C, which is close to the C-rate of 0.6–0.7 C obtained from experiments. In addition, this error correction method can be performed conveniently with only some simple RE measurements of polarization voltages, totally independent of battery electrochemical and geometric parameters. This study provides highly practical error correction method for RE measurements in real LIBs, substantially facilitating the fast diagnosis and safety evaluation of Li plating during charging of LIBs. | Yalun Li Xinlei Gao Xuning Feng Xuebing Han Jiuyu Du Languang Lu Minggao Ouyang | 2022 | Journal of Energy Chemistry2022，31，4： | 0 |
| 19 | Experimental Study on the Effect of State of Charge on Failure Propagation Characteristics within Battery Modules显示文摘To investigate the effect of different states of charge(SOC)on the thermal runaway(TR)propagation behaviors within lithium-ion-batteries based energy storage modules,an experimental setup was developed to conduct failure propagation tests on battery modules at an SOC of 97%,85%,and 50%.The result indicates that an increase in the SOC of batteries can decrease the TR trigger temperature,making batteries trigger TR earlier and reducing the average failure propagation time between two adjacent cells.In addition,the failure propagation tests reveal that at higher SOCs,the TR reaction becomes more violent,the maximal reaction temperature is also much higher,and the damage to the battery module is severe.Compared to the battery module with 97%SOC,the TR trigger time of the battery module with 50%SOC was postponed by approximately 57.8%.Meanwhile,the average failure propagation time got prolonged by approximately 36.0%.Thus,this study can provide references for the thermal safety design of energy-storage battery modules. | Kuijie Li Yalun Li Xinyu Rui Yuancheng Cao Liyun Fan Xuning Feng | 2023 | Chinese Journal of Electrical Engineering2023，9，3： | 0 |
| 20 | Rapid genetic screening of Charcot-Marie-Tooth disease type 1A and hereditary neuropathy with liability to pressure palsies patients显示文摘We used the allele-specific PCR-double digestion method on peripheral myelin protein 22 (PMP22) to determine duplication and deletion mutations in the proband and family members of one family with Charcot-Marie-Tooth disease type 1 and one family with hereditary neuropathy with liability to pressure palsies. The proband and one subclinical family member from the Charcot-Marie-Tooth disease type 1 family had a PMP22 gene duplication; one patient from the hereditary neuropathy with liability to pressure palsies family had a PMP22 gene deletion. Electron microscopic analysis of ultrathin sections of the superficial peroneal nerve from the two probands demonstrated demyelination and myelin sheath hyperplasia, as well as an 'onion-like' structure in the Charcot-Marie-Tooth disease type 1A patient. We observed an irregular thickened myelin sheath and 'mouse-nibbled'-like changes in the patient with hereditary neuropathy with liability to pressure palsies. In the Charcot-Marie-Tooth disease type 1A patient, nerve electrophysiological examination revealed moderate-to-severe reductions in the motor and sensory conduction velocities of the bilateral median nerve, ulnar nerve, tibial nerve, and sural nerve. Moreover, the compound muscle action potential amplitude was decreased. In the patient with hereditary neuropathy with liability to pressure palsies, the nerve conduction velocity of the bilateral tibial nerve and sural nerve was moderately reduced, and the nerve conduction velocity of the median nerve and ulnar nerve of both upper extremities was slightly reduced. | Xiaobo Li Xiaohong Zi Lin Li Yajing Zhan Shunxiang Huang Jin Li Xuning Li Xigui Li Zhengmao Hu Kun Xia Beisha Tang Ruxu Zhang | 2012 | Neural Regeneration Research2012，7，32： | 0 |
