2Changes in circulating Foxp3^+ regulatory T cells and interleukin-17-producing T helper cells during HBV-related acute-on-chronic liver failure显示文摘AIM:To longitudinally investigate cytokine gene expression and protein levels in Th17 and Treg cells,to observe T-cell phenotypes during hepatitis B virus(HBV)-related acute-on-chronic liver failure(ACHBLF)and to analyze changes in Th17 and Treg phenotypes during disease progression.METHODS:We measured the expression of seven Th17/Treg differentiation-related genes and serum concentrations of the corresponding cytokines in 18ACHBLF,18 chronic hepatitis B(CHB)disease controls and 10 healthy controls(HCs)by real-time quantitative pCR and enzyme linked immunosorbent assay.peripheral Th17 and Treg cell frequencies were analyzed by flow cytometry.RESULTS:From the onset of ACHBLF,patients presented with a conductive Th17 differentiation cytokine environment accompanied by high Th17 frequency and high serum IL-17 levels,which were sustained throughout the disease course.The Treg-related cytokine IL-2and Foxp3 were also up-regulated from disease onset,and Foxp3 gene expression showed a gradually increasing trend during ACHBLF.The circular phenotype of Treg and Th17 cells showed changes from the onset of ACHGLF.At disease onset,Th17 frequency increased significantly compared with both CHB and HCs,but Treg cell frequency decreased significantly compared with CHB.During the ACHBLF event,Th17 frequency remained higher compared with HCs,but decreased sharply from the peak point to the recovery point;Treg cell frequency increased gradually during the ACHBLF event.Treg and Th17 cell counts correlated with ACHBLF development;in all patients,serum IL-17 levels significantly correlated with patient serum ALT levels.In survivors,Th17 frequency at the onset point and the Treg to Th17 ratio at the peak point correlated with the patient’s model for end stage liver disease(MELD)plus sodium(MELD-Na)score.The Treg to Th17 ratio and the Th17 frequency at onset were significant predictors of patient survival.Low Treg/Th17 cell ratios at the onset predicted poor survival.Survivors exhibited an initial decrease in the circulating Treg/Th17 ratio from the onset to the peak time,and subsequently displayed a continuous increase.CONCLUSION:Treg and Th17 cells showed changes in genes,protein levels and T cell phenotypes during ACHBLF events.An increased Treg/Th17 ratio was associated with the survival of ACHBLF patients.Xue-Song Liang Cheng-Zhong Li Yin Zhou Wei Yin Ya Yun Liu Wen-Han Fan 2014World Journal of Gastroenterology2014,20,26:44
3A hybrid dynamic programming-rule based algorithm for real-time energy optimization of plug-in hybrid electric bus显示文摘The optimization of the control strategy of a plug-in hybrid electric bus(PHEB) for the repeatedly driven bus route is a key technique to improve the fuel economy. The widely used rule-based(RB) control strategy is lacking in the global optimization property, while the global optimization algorithms have an unacceptable computation complexity for real-time application. Therefore, a novel hybrid dynamic programming-rule based(DPRB) algorithm is brought forward to solve the global energy optimization problem in a real-time controller of PHEB. Firstly, a control grid is built up for a given typical city bus route, according to the station locations and discrete levels of battery state of charge(SOC). Moreover, the decision variables for the energy optimization at each point of the control grid might be deduced from an off-line dynamic programming(DP) with the historical running information of the driving cycle. Meanwhile, the genetic algorithm(GA) is adopted to replace the quantization process of DP permissible control set to reduce the computation burden. Secondly, with the optimized decision variables as control parameters according to the position and battery SOC of a PHEB, a RB control is used as an implementable controller for the energy management. Simulation results demonstrate that the proposed DPRB might distribute electric energy more reasonably throughout the bus route, compared with the optimized RB. The proposed hybrid algorithm might give a practicable solution, which is a tradeoff between the applicability of RB and the global optimization property of DP.ZHANG Ya Hui JIAO Xiao Hong LI Liang YANG Chao ZHANG Li Peng SONG Jian 2014Science China(Technological Sciences)2014,57,12:20
4Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng 2016Biomedical and Environmental Sciences2016,29,3:18
5Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang 2014Biomedical and Environmental Sciences2014,27,5:17
6Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders.XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu 2015Science China(Life Sciences)2015,58,9:12
7Intravenous tirofiban therapy for patients with capsular warning syndrome显示文摘Background Capsular warning syndrome(CWS)is defined as recurrent episodes of transient ischaemic attacks≥3 times during a short time frame.There is no effective therapy to stop these attacks.We,herein,report our experience of using intravenous tirofiban to treat CWS.Methods All patients with CWS in our hospital from January 2013 to September 2017 were reviewed.Patients in tirofiban group(T-group)were treated by intravenous tirofiban at 0.4μg/kg/min for 30 min followed by 0.1-0.15μg/kg/min infusion.Other treatments(non-T-group)included thrombolytic,oral antiplatelet agents and anticoagulant.Intracerebral haemorrhage(ICH),systematic bleeding,new attacks after treatment,National Institutes of Health Stroke Scale(NIHSS)scores at 24 hours and modified Rankin Scales(mRSs)at 3 months were recorded.Descriptive statistics were used for analysis.results Of 23 patients qualified(15 in T-group,8 in non-T-group),the duration of symptoms ranged from 2 to 100 min before treatments.After treatment,in T-group,four patients(26.7%)had recurrent attacks,and NIHSS scores were 0 in 11 patients(73.3%)at 24 hours.All patients reached a favourable outcome(mRS≤2) at 3 months.In non-T-group,five patients(62.5%)had new attacks.NIHSS scores were 0 in two patients(25%)at 24 hours.At 3 months,seven patients(87.5%)reached a favourable outcome.Neither ICH nor systematic bleeding or thrombocytopaenia occurred in both groups of patients.Conclusions Intravenous tirofiban can be a potentially effective and safe therapy to stop early symptomatic fluctuations and shorten the duration of functional deficits in patients with CWS.Wei Li Ya Wu Xiao-Shu Li Cheng-Chun Liu Shu-Han Huang Chun-Rong Liang Huan Wang Li-Li Zhang Zhi-Qiang Xu Yan-Jiang Wang Meng Zhang 2019Stroke & Vascular Neurology2019,4,1:9

9Endovascular therapy for Acute ischemic Stroke Trial (EAST): study protocol for a prospective, multicentre control trial in China显示文摘Background and purpose:5 recent trials have shown the benefit of endovascular treatment for acute ischaemic stroke(AIS)due to large vessel occlusion of the anterior circulation.This study aims to evaluate the safety and efficacy of Solitaire thrombectomy in patients with moderate-to-severe stroke in the Chinese population,which has a high prevalence of intracranial atherosclerosis.Methods and analysis:This multicentre prospective control study will involve 17 stroke centres in China,and plans to recruit 150 patients in the intervention group,and 150 patients in the medical group,in which patients meet enrolment criteria but refuse intervention.Patients with AIS due to large vessel occlusion indicated for treatment with Solitaire stent retriever within 12 hours of symptom onset,and who meet the inclusion and exclusion criteria,will be enrolled in this study.The primary efficacy endpoint is functional independence as defined by a modified Rankin Scale(mRS)score≤2 at 90 days or by functional improvement as defined by mRS,using shift analysis.The procedural efficacy endpoint is arterial recanalisation of the occluded target vessel measured by a modified Thrombolysis in Cerebral Infarction(mTICI)score equal or superior to 2b right following the use of the study device.The primary safety endpoint is symptomatic intracranial haemorrhage(sICH)within 24±3 hours postprocedure.Ethics and dissemination:The protocol was approved by the Ethics Committee at the coordinating centre and by the local Institutional Review Board of each participating centre.Trial registration number:NCT02350283.Zhongrong Miao Xiaochuan Huo Feng Gao Xiaoling Liao Chunjuan Wang Ya Peng Yibin Cao Shengli Chen Meng Zhang Changchun Jiang Xiaoxiang Peng Cunfeng Song Liping Wei Qiyi Zhu Zaiyu Guo Li Liu Hang Lin Hua Yang Wei Wu Hui Liang Anding Xu Kangning Chen Xingquan Zhao Yuesong Pan Hao Li Liping Liu Yilong Wang Yongjun Wang EAST investigators 2016Stroke & Vascular Neurology2016,1,2:8
10Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8
11Ursodeoxycholic acid induces apoptosis in hepatocellular carcinoma xenografts in mice显示文摘AIM: To evaluate the efficacy of ursodeoxycholic acid(UDCA) as a chemotherapeutic agent for the treatment of hepatocellular carcinoma(HCC).METHODS: BALB/c nude mice were randomized into four groups 24 h before subcutaneous injection of hepatocarcinoma BEL7402 cells suspended in phosphate buffered saline(PBS) into the right flank. The control group(n = 10) was fed a standard diet while treatment groups(n = 10 each) were fed a standard daily diet supplemented with different concentrations of UDCA(30,50 and 70 mg/kg per day) for 21 d. Tumor growth was measured once each week,and tumor volume(V) was calculated with the following equation: V =(L × W2) × 0.52,where L is the length and W is the width of the xenograft. After 21 d,mice were killed under ether anesthesia,and tumors were excised and weighed. Apoptosis was evaluated through detection of DNA fragmentation with gel electrophoresis and the terminaldeoxynucleotidyl transferase-mediated d UTP-biotin nick end labeling(TUNEL) assay. Western blot analysis was performed to determine the expression of apoptosisrelated proteins BAX,BCL2,APAF1,cleaved caspase-9,and cleaved caspase-3.RESULTS: UDCA suppressed tumor growth relative to controls. The mean tumor volumes were the following: control,1090 ± 89 mm3; 30 mg/kg per day,612 ± 46 mm3; 50 mg/kg per day,563 ± 38 mm3; and 70 mg/kg per day,221 ± 26 mm3. Decreased tumor volumes reached statistical significance relative to control xenografts(30 mg/kg per day,P < 0.05; 50 mg/kg per day,P < 0.05; 70 mg/kg per day,P < 0.01). Increasing concentrations of UDCA led to increased DNA fragmentation observed on gel electrophoresis and in the TUNEL assay(control,1.6% ± 0.3%; 30 mg/kg per day,2.9% ± 0.5%; 50 mg/kg per day,3.15% ± 0.7%,and 70 mg/kg per day,4.86% ± 0.9%). Western blot analysis revealed increased expression of BAX,APAF1,cleaved-caspase-9 and cleaved-caspase-3 proteins,which induce apoptosis,but decreased expression of BCL2 protein,which is an inhibitor of apoptosis,following administration of UDCA. CONCLUSION: UDCA suppresses growth of BEL7402 hepatocellular carcinoma cells in vivo,in part through apoptosis induction,and is thus a candidate for therapeutic treatment of HCC.Hui Liu Hong-Wei Xu Yu-Zhen Zhang Ya Huang Guo-Qing Han Tie-Jun Liang Li-Li Wei Cheng-Yong Qin Cheng-Kun Qin 2015World Journal of Gastroenterology2015,21,36:7
12Would integrated Western and traditional Chinese medicine have more benefits for stroke rehabilitation? A systematic review and meta-analysis显示文摘Background Stroke is a major cause of death or long-term disability worldwide.Many patients with stroke receive integrative therapy consisting of Western medicine(WM)and routine rehabilitation in conjunction with Chinese medicine(CM),such as acupuncture and Chinese herbal medicine.However,there is no available evidence on the effectiveness of the combined use of WM and CM interventions in stroke rehabilitation.Aims The purpose of this meta-analysis is to evaluate the results of all individual studies to assess the combined use of CM and WM in stroke rehabilitation compared with WM only.Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed.MEDLINE,EMBASE,Cochrane and China National Knowledge Infrastructure(CNKI)were searched.The included outcomes were dependency,motor function,depression and swallowing function.Subgroup analysis was performed,and publication bias was assessed using funnel plots.Summary of review 58 studies and 6339 patients were included in the meta-analysis.Subgroup analysis revealed that combined therapy comprising both acupuncture and WM had a superior effect on improving dependency and swallowing function compared with standard WM therapy alone.Potential superiority of combined therapy comprising CM and WM in improving depression compared with standard WM therapy was also found.Conclusions Our results indicate that the combined use of CM and WM could be more efficacious in stroke rehabilitation compared with the use of WM therapy alone.However,most studies were short in duration(2 to 4 weeks)and prone to different types of biases,which prevents making any conclusion regarding the long-term effects and raises concerns regarding true efficacy in context of high likelihood of Hawthorn bias.So,more randomised controlled trials with more rigorous design and longer duration of treatment and follow-up need to be conducted to compare WM alone versus WM and CM combined.Linda LD Zhong Ya Zheng Alexander Y Lau Norman Wong Liang Yao Xingyao Wu Tengteng Shao Zhenxing Lu Huijuan Li Chun Sum Yuen Jianwen Guo Suzanne Lo Janita Chau Kam Wa Chan Bacon Fung Leung Ng Zhaoxiang Bian Edwin Chau-leung Yu 2022Stroke & Vascular Neurology2022,7,1:7
13The Lyman-alpha Solar Telescope(LST) for the ASO-S mission——Ⅱ. design of LST显示文摘As one of the three payloads for the Advanced Space-based Solar Observatory(ASO-S)mission,the Lyman-alpha(Lyα)Solar Telescope(LST)is composed of three instruments:a Solar Corona Imager(SCI),a LyαSolar Disk Imager(SDI)and a full-disk White-light Solar Telescope(WST).When working in-orbit,LST will simultaneously perform high-resolution imaging observations of all regions from the solar disk to the inner corona up to 2.5 R⊙(R⊙stands for the mean solar radius)with a spatial resolution of 4.8′′and 1.2′′for coronal and disk observations,respectively,and a temporal resolution of 30–120 s and 1–120 s for coronal and disk observations,respectively.The maximum exposure time can be up to20 s due to precise pointing and image stabilization function.Among the three telescopes of LST,SCI is a dual-waveband coronagraph simultaneously and independently observing the inner corona in the HI Lyα(121.6±10 nm)line and white light(WL)(700±40 nm)wavebands by using a narrowband Lyαbeam splitter and has a field of view(FOV)from 1.1 to 2.5 R⊙.The stray-light suppression level can attain<10^-6 B⊙(B⊙is the mean brightness of the solar disk)at 1.1 R⊙and≤5×10^-8 B⊙at 2.5 R⊙.SDI and WST are solar disk imagers working in the Lyαline and 360.0 nm wavebands,respectively,which adopt an off-axis two-mirror reflective structure with an FOV up to 1.2 R⊙,covering the inner coronal edge area and relating to coronal imaging.We present the up-to-date design for the LST payload.Bo Chen Hui Li Ke-Fei Song Quan-Feng Guo Pei-Jie Zhang Ling-Ping He Shuang Dai Xiao-Dong Wang Hai-Feng Wang Chun-Long Liu Hong-Ji Zhang Guang Zhang Yunqi Wang Shi-Jie Liu Hong-Xin Zhang Lei Liu Shi-Lei Mao Yang Liu Jia-Hao Peng Peng Wang Liang Sun Yang Liu Zhen-Wei Han Yan-Long Wang Kun Wu Guang-Xing Ding Peng Zhou Xin Zheng Ming-Yi Xia Qing-Wen Wu Jin-Jiang Xie Ya Chen Shu-Mei Song Hong Wang Bo Zhu Chang-Bo Chu Wen-Gang Yang Li Feng Yu Huang Wei-Qun Gan Ying Li Jing-Wei Li Lei Lu Jian-Chao Xue Bei-Li Ying Ming-Zhe Sun Cheng Zhu Wei-Min Bao Lei Deng Zeng-Shan Yin 2019Research in Astronomy and Astrophysics2019,19,11:6
14Effect and Safety of CX-DZ-ⅡIntelligent Electroacupuncture Therapeutic Instrument for Neck Pain Caused by Cervical Spondylos:Study Protocol for A Randomized Controlled Trial显示文摘Background: Neck pain caused by cervical spondylosis(CS) is a chronic pain condition, with an increasingly high incidence in the general population. Electroacupuncture is a common analgesic modality that has been widely applied in neck pain treatment. However, current electroacupuncture instruments used in the clinic have low intelligence levels and obscure parameter standards. We here designed this study for assessing the effect and safety of a new, intelligent electroacupuncture instrument, the CX-DZ-Ⅱ, in treating neck pain. Methods: The present study is a prospective, two-center, randomized, controlled, open-label, non-inferiority trial for CX-DZ-Ⅱ on treating neck pain caused by CS. Totally 160 eligible patients will be included in this trial and randomly assigned to an experimental group and a control group in a 1:1 ratio. A semi-standard acupoint selection strategy will be employed. In the experimental group, selected acupoints will be stimulated by CX-DZ-Ⅱ. Electroacupuncture treatment will be accomplished by a pre-existing electroacupuncture instrument in the control group. The duration of treatment will be 2 weeks. The primary outcome is the change of Visual Analog Scale(VAS) score after one course of treatment. The secondary outcomes include the VAS scores after each treatment, the responder rate, drug-usage rate of non-steroidal antipyretic analgesics, the rate of adverse events occurrence, and the performance of instrument. Discussion: This study will evaluate the effect and safety of the CX-DZ-Ⅱ intelligent electroacupuncture therapeutic instrument in comparison with a pre-existing non-intelligent instrument in the treatment of neck pain caused by CS. The results will hopefully demonstrate a more optimal electroacupuncture instrument for the treatment of neck pain.(Trial registration No. gov NCT03005301).CHEN Zhi-han LIANG Fan-rong YANG Ming-xiao LI De-hua ZHANG Ya REN Yu-lan 2020Chinese Journal of Integrative Medicine2020,26,5:6
15Warm temperature compromises JA-regulated basal resistance to enhance Magnaporthe oryzae infection in rice显示文摘Changes in global temperatures profoundly affect the occurrence of plant diseases.It is well known that rice blast can easily become epidemic in relatively warm weather.However,the molecular mechanism remains unclear.In this study,we show that enhanced blast development at a warm temperature(22C)compared with the normal growth temperature(28C)is rice plant-determined.Comparative transcriptome analysis revealed that jasmonic acid(JA)biosynthesis and signaling genes in rice could be effectively induced by Magnaporthe oryzae at 28C but not at 22C.Phenotypic analyses of the osaoc1 and osmyc2 mutants,OsCOI1 RNAi lines,and OsMYC2-OE plants further demonstrated that compromised M.oryzaeinduced JA biosynthesis and signaling lead to enhanced blast susceptibility at the warm temperature.Consistent with these results,we found that exogenous application of methyl jasmonate served as an effective strategy for improving blast resistance under the warm environmental conditions.Furthermore,decreased activation of JA signaling resulted in the downregulated expression of some key basal resistance genes at 22C when compared with 28C.Among these affected genes,OsCEBiP(chitin elicitorbinding protein precursor)was found to be directly regulated by OsMYB22 and its interacting protein OsMYC2,a key component of JA signaling,and this contributed to temperature-modulated blast resistance.Taken together,these results suggest that warm temperature compromises basal resistance in rice and enhances M.oryzae infection by reducing JA biosynthesis and signaling,providing potential new strategies for managing rice blast disease under warm climate conditions.Jiehua Qiu Junhui Xie Ya Chen Zhenan Shen Huanbin Shi Naweed I.Naqvi Qian Qian Yan Liang Yanjun Kou 2022Molecular Plant2022,15,4:5

17Cells in G_2/M phase increased in human nasopharyngeal carcinoma cell line by EBV-LMP1 through activation of NF-кB and AP-1显示文摘Although previous studies showed that the principal oncoprotein encoded by Epstein-Barr virus, latent membrane protein 1 (LMP1), could induce the nasopharyngeal carcinoma cells in G2/M phase increased, littleis known about the target molecules and mechanisms. The present study demonstrated that LMP1 couldinduce the accumulation of p53 protein and upregulate its transactivity in a dose dependent manner, whichresulted in the decrease of the kinase activity of cdc2/cyclin B complex and inducing arrest at G2/M phasethrough the activation of NF-kB and AP-1 signaling pathways, and the effect of NF-kB was more obviousthan that of AP-1. This study provided some significant evidence for further elucidating the molecular mechanisms that LMP1 had effects on the surveillance mechanism of cell cycle and promoting the survivalof transformed cells and tumorigenesis.LIN DENG,JING YANG,XIAO RONG ZHAO,XI YUN DENG,LIANG ZENG,HUAN HUA GU,MIN TANG,YA CAOCancer Research Institute,Xiangya School of Medicine,Central South University,Xiangya Road 88,Chang-sha,Hunan 410078,China 2003Cell Research2003,13,3:5
18Hexagonal boron nitride nanosheet for effective ambient N2 fixation to NH3显示文摘Industrial production of NH3 from N2 and H2 significantly relies on Haber-Bosch process,which suffers from high energy consume and CO2 emission.As a sustainable and environmentally-benign alternative process,electrochemical artificial N2 fixation at ambient conditions,however,is highly required efficient electrocatalysts.In this study,we demonstrate that hexagonal boron nitride nanosheet (h-BNNS) is able to electrochemically catalyze N2 to NH3.In acidic solution,h-BNNS catalyst attains a high NH3 formation rate of 22.4 μg·h-1·mg-1cat.and a high Faradic efficiency of 4.7% at-0.75 V vs.reversible hydrogen electrode,with excellent stability and durability.Density functional theory calculations reveal that unsaturated boron at the edge site can activate inert N2 molecule and significantly reduce the energy barrier for NH3 fonmation.Ya Zhang Huitong Du Yongjun Ma Lei Ji Haoran Guo Ziqi Tian Hongyu Chen Hong Huang Guanwei Cui Abdullah M.

19The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels.Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu 2022Science China(Life Sciences)2022,65,12:4
20Nanoprobes for super-resolution fluorescence imaging at the nanoscale显示文摘Compared with other imaging techniques,fluorescence microscopy has become an essential tool to study cell biology due to its high compatibility with living cells.Owing to the resolution limit set by the diffraction of light,fluorescence microscopy could not resolve the nanostructures in the range of<200 nm.Recently,many techniques have been emerged to overcome the diffraction barrier,providing nanometer spatial resolution.In the course of development,the progress in fluorescent probes has helped to promote the development of the high-resolution fluorescence nanoscopy.Here,we describe the contributions of the fluorescent probes to far-field super resolution imaging,focusing on concepts of the existing super-resolution nanoscopy based on the photophysics of fluorescent nanoprobes,like photoswitching,bleaching and blinking.Fluorescent probe technology is crucial in the design and implementation of super-resolution imaging methods.HOU ShangGuo LIANG Le DENG SuHui CHEN JianFang HUANG Qing CHENG Ya FAN ChunHai 2014Science China Chemistry2014,57,1:4
