2Effects of acrous gramineus and its component, alpha-asarone, on apoptosis of hippocampal neurons after seizure in immature rats显示文摘BACKGROUND: α-asarone and acrous gramineus have been shown to play a necessary function in enhancing the reactivity and convulsant threshold to electric stimulation of immature rats. They have also been shown to effectively suppress epileptic seizures induced by pentylenetetrazol in young rats. However, the mechanisms for these roles have been still unclear. OBJECTIVE: To observe the effects in immature rats of acrous gramineus and α-asarone on apoptosis of hippocampal neurons after epileptic seizure at the protein level, and to analyze the mechanism for these effects. DESIGN: A randomized controlled animal experiment. SETTINGS: Department of Pediatrics, First Hospital of Jilin University; Department of Histology and Embryology, Norman Bethune Medical School of Jilin University; Department of Internal Medicine, Children's Hospital of Changchun City; Department of Neurology, First Clinical Hospital affiliated to Harbin Medical University. MATERIALS: Fifty 3-week old Wistar rats, 34-40 g, irrespective of gender, were provided by Gaoxin Research Center of Medical Animal Experiment, Changchun. The animals were treated according to the animal ethical standards. The following chemicals were used for this study: acrous gramineus powders or infusion (Batch No. 0307113, Tianjiang Medicine Company Limited, Jiangyin), α-asarone tablets (Batch No. 030219, Tianwei Pharmaceutical Factory, Shenyang), and phenobarbital sodium tablets (Batch No. 020608, Xinya Medicine Company Limited, Shanghai). The animals were divided into five groups randomly. First, ten rats were chosen as the normal controls. The remaining rats were treated with i.p. injections of pentylenetetrazol to stimulate an epileptic model. METHODS: The experiments were performed at the Neurological Laboratory of the First Hospital of Jilin University between October and December 2004. The rats were treated with i.p. injections of pentylenetetrazol (60 mg/kg) to establish an epileptic model. According to Racine' s standard, animals that reached stage 4 and 5 were chosen and randomly divided into 4 groups: model group, phenobarbital sodium, acrous gramineus, and α-asarone group. The normal control group was treated with an i.p. injection of physiological saline (0.5 mL). After modeling, the model groups were intragastrically administrated 0.5 mL saline. The phenobarbital sodium, acrous gramineus, and α -asarone groups were intragastrically administrated 18 mg/kg/d phenobarbital sodium, 2 350 mg/kg/d acrous gramineus and 29 mg/kg/d α -asarone, respectively. The course of treatment was twice a day for 7 days. The normal group received intragastric administration of 0.5 mL saline at the same time. The rats were sacrificed and brain sections were prepared for light microscopy and electron microscopy. MAIN OUTCOME MEASURES: ① Pathological changes of CA1 and CA3 hippocampal region neurons were observed by light microscopy and electronic microscopy. ② Neuronal apoptosis in the CA1 and CA3 region was measured by TUNEL staining. ③ Bcl-2 and Bax expression in CA1 and CA3 region neurons was detected by immunohistochemistry and a ratio of Bcl-2/Bax was calculated. RESULTS: All 50 immature rats were included in the final analysis. ① Pathological changes of CA1 and CA3 region hippocampal neurons: there were different pathological changes in all groups other than the normal control group. The number of damaged neurons in the model group was highest. The phenobarbital sodium, acrous gramineus, and α-asarone group exhibited different degrees of improvement. ② Neuronal apoptosis in the CA1 and CA3 regions: there were less TUNEL-positive cells in the CA1 and CA3 regions in the normal control group. One week after PTZ-induced seizure, numerous TUNEL-positive cells were detected in the CA1 and CA3 regions in the remaining four groups. There was a significant difference between the normal control group and the remaining four groups (t = 12.089-19.162, P < 0.01). The number of TUNEL-positive cells was less in the phenobarbital sodium, acrous gramineus, and α-asarone groupscompared to the model group (t = 4.707-6.268, P < 0.01). ③Bcl-2 and Bax expression of neurons in the CA1 and CA3 regions: The number of Bcl-2- and Bax-positive cells was less in the normal control group. The Bax-positive cells exhibited a normal shape and had large round nuclei that were predominant. One week after PTZ-induced epilepsy, the number of Bcl-2- and Bax-positive cells in the CA1 and CA2 regions was significantly increased in the remaining four groups compared to the normal control group (t = 11.606-27.042, P < 0.01). The Bax-positive cells exhibited a reduced size and nuclear pyknosis was predominant. However, there was no significant difference among the four groups (P > 0.05). The number of Bcl-2-positive cells in the phenobarbital sodium, acrous gramineus, and α -asarone groups were significantly increased compared to the model group (t = 4.051-6.404, P < 0.01). However, the number of Bax-positive cells was not significantly different among the four groups. The ratio of Bcl-2 to Bax expression was approximately 6.0 in the normal controls, 0.7 in the model group, and 1.0 in the remaining three groups. CONCLUSION: Acrous gramineus and α-asarone increased Bcl-2 expression and decreased Bax expression, and also reduced the number of apoptotic hippocampal neurons during PTZ-induced epileptic seizures in immature rats.Libin Yang Shulei Li Yanzhi Huang Jianmin Liang Yuhong Wang 2008Neural Regeneration Research2008,3,1:4
3TRIM35 mediates protection against influenza infection by activating TRAF3 and degrading viral PB2显示文摘Tripartite motif(TRIM)family proteins are important effectors of innate immunity against viral infections.Here we identified TRIM35 as a regulator of TRAF3 activation.Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon(IFN)in response to viral infection.777m35-deficient mice were more susceptible to influenza A virus(IAV)infection than were wild-type mice.TRIM35 promoted the RIG-Imediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1.IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3.TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2,thereby antagonizing its suppression of TRAF3 activation.Our in vitro and in vivo findings thus reveal novel roles of TRIM35,through catalyzing Lys63-or Lys48-linked polyubiquitination,in RIG-I antiviral immunity and mechanism of defense against IAV infection.Nan Sun Li Jiang Miaomiao Ye Yihan Wang Guangwen Wang Xiaopeng Wan Yuhui Zhao Xia Wen Libin Liang Shujie Ma Liling Liu Zhigao Bu Hualan Chen Chengjun Li 2020Protein & Cell2020,11,12:4
4Variation of crystal orientation during epitaxial growth of dendrites by laser deposition显示文摘A nickel-based superalloy was deposited onto a single crystal substrate based on epitaxial laser metal forming(E-LMF). The microstructure development in two depositions has been researched. For the first time, the crystal orientation of dendrites varying beyond 20° was found when the dendrites deflected in deposition. In addition, a new grain boundary was found between different orientation dendrites in a grain, and the detected grain boundary angle was 23°. The result shows that flowing field in laser pool is responsible for this phenomenon.Guowei Wang Jingjing Liang Yizhou Zhou Libin Zhao Tao Jin Xiaofeng Sun 2018Journal of Materials Science & Technology2018,34,4:3
5Model Investigation on Composite Failure Prediction of π-Joint Structures显示文摘This paper was concerned with the tensile mechanics behavior of the composite π-joint under static tensile loading. The numerical strength analysis methodology was presented containing the basis assumption for the analysis, the material modeling, and the selected element type. It was assumed that the composite ply had transverse isotropic material properties and the adhesive had linear elastic properties. With the goal of the strength analysis to determine the onset of the damage initiation and the ultimate failure load, two stiffness degradation models were discussed and a modified maximum stress failure criteria was presented. To verify the numerical model, a pull-off test scheme was performed and the experimental data of five specimens were given. The experimental results indicate that the damage initiation location and the failure load were consistent with numerical predictions and verified the feasibility of the numerical model.Zhao Libin Qin Tianliang Huanghai Liang Xianzhu Chang Haifeng Cao Zhenghua 2009稀有金属材料与工程2009,38,A03:2

9Nanoscale triple-gate FinFET design considerations based on an analytical model of short-channel effects显示文摘In this paper,a three-dimensional(3-D)analytical model for short-channel effects(SCEs)in a nanoscale triple-gate(TG)FinFET is derived based on solving a boundary value problem using the 3-D Poisson’s equation.This model is validated using 3-D numerical simulations(TCAD Sentaurus).Results show that SCEs in a TG FinFET can be controlled by reducing either the fin thickness(D)or height(H).On the other hand,when fixing the drive capability of turn-on current,i.e.fixing the total width of the conductive channel,and changing the ratio of D and H,there exists a case where SCEs are worst,and SCEs can be reduced by either increasing or decreasing the ratio from the worst case.This SCEs model can be used to predict the minimum channel length(Lmin)of a device when D,H,and tox are fixed,while keeping SCEs at a tolerable level.Based on the analytical model,the insights into the physics of SCEs in nanoscale TG FinFET are discussed,and design considerations are investigated.XIE Qian LIANG RenRong WANG Jing LIU LiBin XU Jun 2014Science China(Information Sciences)2014,57,4:1
10NUMERICAL ANALYSIS OF A NONLINEAR SINGULARLY PERTURBED DELAY VOLTERRA INTEGRO-DIFFERENTIAL EQUATION ON AN ADAPTIVE GRID显示文摘In this paper,we study a nonlinear first-order singularly perturbed Volterra integro-differential equation with delay.This equation is discretized by the backward Euler for differential part and the composite numerical quadrature formula for integral part for which both an a priori and an a posteriori error analysis in the maximum norm are derived.Based on the a priori error bound and mesh equidistribution principle,we prove that there exists a mesh gives optimal first order convergence which is robust with respect to the perturbation parameter.The a posteriori error bound is used to choose a suitable monitor function and design a corresponding adaptive grid generation algorithm.Furthermore,we extend our presented adaptive grid algorithm to a class of second-order nonlinear singularly perturbed delay differential equations.Numerical results are provided to demonstrate the effectiveness of our presented monitor function.Meanwhile,it is shown that the standard arc-length monitor function is unsuitable for this type of singularly perturbed delay differential equations with a turning point.Libin Liu Yanping Chen Ying Liang 2022Journal of Computational Mathematics2022,40,2:1
11Generation and application of replication-competent Venus-expressing H5N1,H7N9,and H9N2 influenza A viruses显示文摘The generation and application of replication-competent influenza A virus(IAV) expressing a reporter gene represent a valuable tool to elucidate the mechanism of viral pathogenesis and establish new countermeasures to combat the threat of influenza. Here, replication-competent IAVs with a neuraminidase(NA) segment harboring a fluorescent reporter protein, Venus, were generated in the background of H5N1, H7N9, and H9N2 influenza viruses, the three subtypes of viruses with imminent pandemic potential. All three reporter viruses maintained virion morphology, replicated with similar or slightly reduced titers relative to their parental viruses, and stably expressed the fluorescent signal for at least two passages in embryonated chicken eggs. As a proof of concept, we demonstrated that these reporter viruses,used in combination with a high-content imaging system, can serve as a convenient and rapid tool for the screening of antivirals and host factors involved in the virus life cycle. Moreover, the reporter viruses demonstrated similar growth properties and tissue tropism as their parental viruses in mice, among which the H7N9 NA-Venus virus could potentially be used in ex vivo studies to better understand H7N9 pathogenesis or to develop novel therapeutics.guangwen wang jie zhang fandi kong qibing li jinliang wang shujie ma yuhui zhao libin liang junping li nan sun lizheng guan yuan zhou chenchen zhou shanyu huang zhigao bu li jiang hualan chen chengjun li 2018Science Bulletin2018,63,3:1
12Gene2DGE: A Perl Package for Gene Model Renewal with Digital Gene Expression Data显示文摘For transcriptome analysis, it is critical to precisely define all the transcripts across the whole genome. More and more digital gene expression (DGE) scannings have indicated the presence of huge amount of novel transcripts in addition to the known gene models. However, almost all these studies still depend crucially on existing annotation. Here, we present Gene2DGE, a Perl software package for gene model renewal with DGE data. We applied Gene2DGE to the mouse blastomere transcriptome, and defined 98,532 read-enriched regions (RERs) by read clustering supported by more than four reads for each base pair. Taking advantage of this ab initio method, we refined 2,104 exonic regions (4% of a total of 48,501 annotated transcribed regions) with remarkable extension into un-annotated regions (>50 bp). For 5% of uniquely mapped reads falling within intron regions, we identified 13,291 additional possible exons. As a result, we renewed 4,788 gene models, which account for 39% of a total of 12,277 transcribed genes. Furthermore, we identified 12,613 intergenic RERs, suggesting the possible presence of novel genes outside the existing gene models. In this study, therefore, we have developed a suitable tool for re-newal of known gene models by ab initio prediction in transcriptome dissection.

13Ka-band broadband filtering packaging antenna based on through-glass vias (TGVs)显示文摘This work presents a novel design of Ka-band(33 GHz)filtering packaging antenna(FPA)that features broadband and great filtering response,and is based on glass packaging material and through-glass via(TGV)technologies.Compared to traditional packaging materials(printed circuit board,low temperature co-fired ceramic,Si,etc.),TGVs are more suitable for miniaturization(millimeter-wave three-dimensional(3D)packaging devices)and have superior microwave performance.Glass substrate can realize 3D high-density interconnection through bonding technology,while the coefficient of thermal expansion(CTE)matches that of silicon.Furthermore,the stacking of glass substrate enables high-density interconnections and is compatible with micro-electro-mechanical system technology.The proposed antenna radiation patch is composed of a patch antenna and a bandpass filter(BPF)whose reflection coefficients are almost complementary.The BPF unit has three pairs ofλg/4 slots(defect microstrip structure,DMS)and twoλg/2 U-shaped slots(defect ground structure,DGS).The proposed antenna achieves large bandwidth and high radiation efficiency,which may be related to the stacking of glass substrate and TGV feed.In addition,the introduction of four radiation nulls can effectively improve the suppression level in the stopband.To demonstrate the performance of the proposed design,a 33-GHz broadband filtering antenna is optimized,debugged,and measured.The antenna could achieve|S11|<-10 dB in 29.4‒36.4 GHz,and yield an impedance matching bandwidth up to 21.2%,with the stopband suppression level at higher than 16.5 dB.The measurement results of the proposed antenna are a realized gain of~6.5 dBi and radiation efficiency of~89%.Zhen FANG Jihua ZHANG Libin GAO Hongwei CHEN Wenlei LI Tianpeng LIANG Xudong CAI Xingzhou CAI Weicong JIA Huan GUO Yong LI 2023Frontiers of Information Technology & Electronic Engineering2023,24,6:0
14Consensus on diagnostic criteria for Yin deficiency syndrome in hypertension:a modified Delphi study显示文摘OBJECTIVE:To reach consensus on the diagnostic criteria for Yin deficiency syndrome in hypertension(YDSH)patients by a modified Delphi method.METHODS:Our study was consistent with T/CACM 1032-2017.The methodology of RAND/UCLA appropriateness was used to develop consensus guidance statements.A nationwide panel of experienced clinical experts from 19 provinces was constructed.These experts were all prominent in Traditional Chinese Medicine(TCM)of cardiovascular diseases.This consensus process consisted of two rounds of questionnaires and a final round of consultation to analyze the weight score of each item.Moreover,the data extraction process is carried out independently by third-party researchers(LIANG Junya,SUN Yang,and DU Xiaona).When there is disagreement in all three rounds,the expert panel group(odd number)are invited to vote,and the one with more votes wins.In the questionnaires,participants were asked to rate the appropriateness of each syndrome item using a nine-point Likert scale.The consensus was defined as a panel median rating 1-3 or 7-9 without disagreement.And then the diagnostic criteria of YDSH were formed according to the weight score in the final round.RESULTS:Twenty-eight experts(84.8%)participated in the first round,and thirty-one(93.9%)finished the second round.After two rounds,the consensus of YDSH was reached on 11 items(25.6%),including symptoms,signs,and pulse condition.Twenty-one experts(63.6%)completed the final round in which they used a grading system for each item.Red tongue with scanty fur had the highest weighting(22.8%),followed by heat in the palms and soles(20.1%).CONCLUSIONS:The consensus-based diagnostic criteria for YDSH,formed by a modified Delphi method,can be widely incorporated in TCM.A further clinical study will be conducted to analyze the diagnosis value and cut-off score of our YDSH criteria.HE Yun HE Jing XU Xiangru LI Haixiao SHI Rongwei LIANG Junya ZHOU Ying ZHU Yao CHEN Xiaohu TANG Shuhua XIAO Min ZHAN Libin PEI Yinghao JIANG Weimin 2023Journal of Traditional Chinese Medicine2023,43,1:0
15Chinese herbal medicine combined with cognitive–behavioural therapy for avoidant paruresis:a controlled trial显示文摘Background Avoidant paruresis is a common clinical condition in urology and psychosomatic medicine.However,it has limited treatment options that are safe and effective with few side effects.Aims Our study aimed to investigate the effectiveness and safety of the Chinese herbal Yangxin Tongquan decoction combined with cognitive-behavioural therapy(CBT)for avoidant paruresis.Methods Sixty-eight patients with avoidant paruresis were divided into a treatment group(33 patients)and a control group(35 patients).The control group was assigned 10 weeks of CBT and systematic desensitisation.In addition to CBT and systematic desensitisation,the treatment group was given the Chinese herbal Yangxin Tongquan decoction during the 10-week study.The Shy Bladder Syndrome Scale(SBS)and the Self-rating Anxiety Scale(SAS)were administered before and after treatment to measure any change.Results The overall efficacy in the treatment group(n=30)was 80.0%vs 62.5%in the control group(n=33).Comparing pretreatment and post-treatment measures,both groups showed improvement in SBS scores and SAS scores(treatment group:t_((SBS))=8.397,p_((SBS))<0.001,t_((SAS))=8.216,p_((SAS))<0.001;control group:t_((SBS))=6.802,p_((SBS))<0.001,t_((SAS))=5.171,p_((SAS))<0.001).Moreover,both groups’SBS and SAS scores changed significantly over time(SBS scores:F_(time)=118.299,p<0.001;SAS scores:F_(time)=92.114,p<0.001).However,the treatment group performed better than the control group(SBS scores:F_(time*group)=5.709,p=0.020;SAS scores:F_(time*group)=7.235,p=0.009).Conclusions The Chinese herbal Yangxin Tongquan decoction combined with cognitive-behavioural psychotherapy positively affects the treatment of avoidant paruresis without significant adverse effects.Shijie Liang Ying Zhou Chao Yu Xiang Gao Fangbin Ji Qianyuan Fang Zhihang Zhang Libin Yang Youkang Zhao Yuhui Zhao Renwu Yin Kaimin Chen Zheng Lu 2023General Psychiatry2023,36,5:0

17Beam fanning effect and image storage in Ce:KNSBN crystal显示文摘A non-synchronously-numerating experimental system is applied in this research.The effect of the incident beam intensity I and the beam incident angleθon beam fanning effect is investigated with a singular beam incident on Ce:KNSBN crystal.The results show that the beam fanning effect strongly depends on I andθ.The threshold effect of I for the beam fanning in Ce:KNSBN crystal is observed,and the threshold intensity of incident beam keeps the same value of 38.2 mW/cm 2 for differentθ,and the steady beam fanning intensity Ifsat reaches a peak atθ=15°under the same I.In addition,the effect of the incident beam modulated on the beam fanning noise and holographic storage in Ce:KNSBN crystal is studied.And the results suggest that the beam fanning noise is effectively suppressed,and the quality of the reappearance image is greatly improved.LI PanLai GUO QingLin WANG ZhiJun PANG LiBin LIANG BaoLai 2007Chinese Science Bulletin2007,52,8:0
