1Risk analysis of dynamic control of reservoir limited water level by considering flood forecast error显示文摘Flood control forecast operation mode is one of the main ways for determining the upper bound of dynamic control of flood limited water level during flood season. The floodwater utilization rate can be effectively increased by using flood forecast information and flood control forecast operation mode. In this paper, Dahuofang Reservoir is selected as a case study. At first, the distribution pattern and the bound of forecast error which is a key source of risk are analyzed. Then, based on the definition of flood risk, the risk of dynamic control of reservoir flood limited water level within different flood forecast error bounds is studied. The results show that, the dynamic control of reservoir flood limited water level with flood forecast information can increase the floodwater utilization rate without increasing flood control risk effectively and it is feasible in practice.ZHANG YanPing WANG GuoLi PENG Yong ZHOU HuiCheng 2011Science China(Technological Sciences)2011,54,7:16
2Reproductive 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
3Comparison of clinical effectiveness of acupuncture and a Western drug on allergic rhinitis:study protocol for a randomized controlled trial显示文摘OBJECTIVE: To compare the efficacy of an acupuncture regimen for persistent allergic rhinitis(PER), aimed at improving a patient's mind or Shen in Traditional Chinese Medicine, to that of a second-generation H1-receptor antagonist, cetirizine hydrochloride.METHODS: This multicenter, randomized, controlled clinical trial on PER will be conducted at three institutions in China. The total study period will be 9 weeks. After a 1-week preparatory screening period, 240 eligible participants with PER willbe randomized to receive acupuncture or pharmacotherapy(1∶1) for 4 weeks with a 4-week follow-up. The primary outcome will be changes in7-day average total nasal symptom score. Secondary outcome measures include rhinoconjunctivitis quality of life questionnaire score and total non-nasal symptom score.RESULTS:The presence and seriousness of psychological and emotional impairments should be considered in therapeutic programs for allergic rhinitis.No clinical trial for treating allergic rhinitis via acupuncture regulation of psychological and emotionalactivitieshasbeenreported.CONCLUSION:The findings of the trial will allow us to determine the effects of the mind(Shen)-regulation treatment approach.

4Effect of a comprehensive therapy plus Gushenyutai plaster administered at Guanyuan(CV 4) on male infertility associated with semen non-liquefaction显示文摘OBJECTIVE: To observe the clinical effect of Gushenyutai plaster administered at the Guanyuan(CV4) acupoint on male infertility associated with semen non-liquefaction.METHODS: Sixty-two male patients with infertility caused by semen non-liquefaction were random-ized into a treatment and control group. The control group received comprehensive therapy, which included oral administration of clarithromycin sustained release tablets, hip bath with Zhongyaoxiaoyan granules, prostate massage, and transurethral microwave treatment. The treatment group was administered Gushenyutai plaster in addition to the comprehensive therapy. Both groups were treated for 8 weeks. After treatment, the clinical effect and pregnancy rate were assessed and compared between the two groups.RESULTS: The effective rate of the treatment group was significantly higher than that of the control group(96.77% vs 70.97%, P<0.05) and the pregnancy rates of the treatment group and control groups were 38.71% and 16.13%, respectively(P<0.05).CONCLUSION: The effect of Gushenyutai plaster plus comprehensive therapy was better than that of the comprehensive therapy alone on male infertility induced by semen non-liquefaction.Shaofang Peng Yanping Zheng Kangzhuang Zheng Ke Lin Juhong Wu Wenqin Zheng Yongzhong Li Yang Li Chuangjian Lin 2014Journal of Traditional Chinese Medicine2014,34,6:6
5Identification of three major Bemisia tabaci biotypes in China based on morphological and DNA polymorphisms显示文摘The sweet potato whitefly, Bemisia tabaci, is a complex species, and many of its biotypes are important agricultural pests. The B and Q biotypes are invasive and coexist with the native Cv biotype on vegetable and ornamental crops in China. In this study, these three bio- types were identified based on their morphological characteristics, RAPD-PCR analysis, and DNA sequences of the COI gene. The ante-rior and posterior wax fringes of the B, Q, and Cv biotypes significantly differed from each other. Based on this morphological characteristic, the three biotypes can easily be distinguished in greenhouses and fields. Genomic DNA RAPD-PCR band patterns also revealed differences between these biotypes using the H16 primer. The B biotype has three bright DNA bands between 250 and 600 bp, the Q biotype only has one bright band at 300 bp, while the Cv biotype has no band between 250 and 500 bp. Both the Cv and Q biotypes have two bright bands at 750 and 1000 bp while the B biotype has only one band at 1000 bp. Based on the COI gene, the genetic identity between B and Cv, B and Q, and Q and CV was 85.8%, 94.7%, and 86.0%, respectively. The MP tree indicated that the phylogenetic relationship between the B and Q biotypes is much closer than that between the B and Cv or the Q and Cv biotypes. The uses of the morphological, RAPD-PCR, and DNA sequencing methods in biotype identification of B. tabaci are discussed.Baoli Qiu Yanping Chen Li Liu Weilu Peng Xiaoxi Li Muhammad Z.

6Precise temporal regulation of Dux is important for embryo development显示文摘Dear Editor,Zygotic genome activation(ZGA)following fertilization is accomplished through a process termed the maternal-to-zygotic transition,during which the maternal RNAs and proteins are degraded and zygotic genome is transcriptionally activated.In mice,minor ZGA occurs from S phase of the zygote to G1 phase of the two-cell(2C)embryo,while major ZGA takes place during the middle-to-late 2C stage with a burst of transcription of totipotent cleavage stage-specific genes and retrotransposons.Mingyue Guo Yanping Zhang Jianfeng Zhou Yan Bi Junqin Xu Ce Xu Xiaochen Kou Yanhong Zhao Yanhe Li Zhifen Tu Kuisheng Liu Jiaming Lin Peng Yang Shaorong Gao Yixuan Wang 2019Cell Research2019,29,11:5
7Effects of exogenous ABA application on post-anthesis dry matter redistribution and grain starch accumulation of winter wheat with different staygreen characteristics显示文摘The objective of this study was to investigate whether and how exogenous abscisic acid(ABA)is involved in mediating starch accumulation in the grain and redistribution of carbohydrates during grain filling of two wheat cultivars with different staygreen characteristics.At blooming stage,plants of Wennong 6(a staygreen cultivar)and Jimai 20(control)were sprayed with10 mg L-1abscisic acid(ABA)for 3 days.The application of ABA significantly(P<0.05)increased grain filling rate,starch accumulation rate and content,remobilization of dry matters to kernels,and 1000-grain weight of the two cultivars.Exogenous ABA markedly(P<0.05)increased grain yield at maturity,and Wennong 6 and Jiami 20 showed 14.14%and 4.86%higher compared yield than the control.Dry matter accumulation after anthesis of Wennong 6 was also significantly(P<0.05)influenced by exogenous ABA,whereas that of Jimai 20 was unchanged.Application of ABA increased endogenous zeatin riboside(ZR)content 7 days after anthesis(DAA),and spraying ABA significantly increased endogenous indole-3-acetic acid(IAA)and ABA contents from 7 to 21 DAA and decreased gibberellin(GA3)content at 14 DAA,but increased GA3content from 21 to 35 DAA.The results suggested that increased yield of staygreen was due to greater starch assimilation owing to a higher filling rate and longer grain-filling duration.Dongqing Yang Yongli Luo Yingli Ni Yanping Yin Weibing Yang Dianliang Peng Zhengyong Cui Zhenlin Wang 2014The Crop Journal2014,2,Z1:3
8Can nanoparticles and nano-protein interactions bring a bright future for insulin delivery?显示文摘Insulin therapy plays an essential role in the treatment of diabetes mellitus.However,frequent injections required to effectively control the glycemic levels lead to substantial inconvenience and low patient compliance.In order to improve insulin delivery,many efforts have been made,such as developing the nanoparticles (NPs)-based release systems and oral insulin.Although some improvements have been achieved,the ultimate results are still unsatisfying and none of insulin-loaded NPs systems have been approved for clinical use so far.Recently,nano?protein interactions and protein corona formation have drawn much attention due to their negative influence on the in vivo fate of NPs systems.As the other side of a coin,such interactions can also be used for constructing advanced drug delivery systems.Herein,we aim to provide an insight into the advance and flaws of various NPs-based insulin delivery systems.Particularly,an interesting discussion on nano?protein interactions and its potentials for developing novel insulin delivery systems is initiated.Ting Zhang James Zhenggui Tang Xiaofan Fei Yanping Li Yi Song Zhiyong Qian Qiang Peng 2021Acta Pharmaceutica Sinica B2021,11,3:3
9Efficacy and safety of rasagiline in Chinese patients with early Parkinson’s disease:a randomized, double-blind,parallel,placebo-controlled,fixed-dose study显示文摘Background:Rasagiline is a monoamine oxidase-B inhibitor used for Parkinson’s disease(PD)treatment,but its effectiveness on Chinese patients is unclear.This study aimed to evaluate the efficacy and safety of rasagiline monotherapy in Chinese patients with early PD.Methods:A 26-weeks,randomized,double-blind,placebo-controlled study has been performed at 15 sites in China and enrolled outpatients(≥35 years old)with idiopathic PD without a history of using any dopaminergic drugs.Participants were randomized 1:1 to receive rasagiline 1 mg once daily or placebo.The primary endpoint was the change of the Unified Parkinson’s Disease Rating Scale(UPDRS)total score from baseline to 26 weeks treatment.Secondary endpoints included changes in UPDRS subscale scores from part Ⅰ to Ⅲ.Health status was assessed with the PD Questionnaire(PDQ)-39 and EuroQol-Five-Dimension(EQ-5D)questionnaire.Safety profile was collected until 30 weeks after randomization.Results:A total of 130 patients(n=65/group)were recruited,and 127(rasagiline,n=64;placebo,n=63)were included in the full analysis set.Baseline characteristics were comparable between the two groups.The decrease in the mean UPDRS total score was greater in the rasagiline group than in the placebo group(−3.18±0.95 vs.−0.18±0.98,P=0.025),and the mean UPDRS part I non-motor symptoms score(−0.54±0.15 vs.-0.08±0.15,P=0.003)were significantly decreased in the rasagiline group compared with placebo treated patients.An improvement trend was observed in the active treatment group for the subscales evaluation with parts Ⅱ and Ⅲ,while the difference to placebo was not statistically significant.Life quality assessed by the EQ-5D visual analog scale improved in the rasagiline group but worsened in placebo treated patients.The overall incidence of treatment-emergent adverse events(AEs)was slightly lower in the rasagiline group(41.5%)than in the placebo group(46.2%).Conclusions:Rasagiline is effective,safe,and well tolerated as monotherapy for the treatment of Chinese PD patients.Zhenxin Zhang Jian Wang Shengdi Chen Chunfeng Liu Baorong Zhang Rong Peng Shenggang Sun Xiangru Sun Gang Zhao Qiumin Qu Yansheng Li Suiqiang Zhu Xiaoping Pan Ming Shao Yanping Wang 2018Translational Neurodegeneration2018,7,1:3
10Surface Roughness and Roundness of Bearing Raceway Machined by Floating Abrasive Polishing and Their Effects on Bearing's Running Noise显示文摘As the two most important indexes of bearing raceway,surface roughness and roundness have significant influence on bearing noise.Some researchers have carried out studies in this field,however,reason and extent of the influence of raceway surface geometric characteristics on bearing running noise are not perfectly clear up to now.In this paper,the raceway of 6309 type bearing’s inner and outer ring is machined by floating abrasive polishing adopting soft abrasive pad.Surface roughness parameters,arithmetical mean deviation of the profile Ra,the point height of irregularities Rz,maximum height of the profile Rmax and roundness f of raceways,are measured before and after machining,and the change rules of the measured results are studied.The study results show that the floating abrasive polishing can reduce the surface geometric errors of bearing raceway evidently.The roundness error is reduced by 25%,Rmax value is reduced by 35.5%,Rz value is reduced by 22%and Ra value is reduced by 5%.By analyzing the change of the geometrical parameters and the shape difference of the raceway before and after machining,it is found that the floating abrasive polishing method can affect the roundness error mainly by modifying the local deviation of the raceway’s surface profile.Bearings with different raceway surface geometrical parameter value are assembled and the running noise is tested.The test results show that Ra has a little,Rmax and Rz have a measurable,and the roundness error has a significant influence on the running noise.From the viewpoint of controlling bearings’running noise,raceway roundness error should be strictly controlled,and for the surface roughness parameters,Rmax and Rz should be mainly controlled.This paper proposes an effective method to obtain the low noise bearing by machining the raceway with floating abrasive polishing after super finishing.PANG Guibing QI Xuezhi MA Qinyi ZHAO Xiujun WEN Chunsheng XU Wenji PENG Yanping 2014Chinese Journal of Mechanical Engineering2014,27,3:3
11Ultrathin nanosheets of cobalt-nickel hydroxides hetero-structure via electrodeposition and precursor adjustment with excellent performance for supercapacitor显示文摘A homogeneous better-dispersed ultrathin nanosheets(ca. 5 nm) of cobalt-nickel layered double hydroxides(LDH) supported on nickel foam scaffold was synthesized using controllable electrodeposition approach for high efficiency electrode materials of new supercapacitor. The morphology and electrochemical performances of the samples can be controlled by adjusting the precursor ratio, i.e., Ni(OAc)_2/Co(NO_3)_2 molar ratio in the electrodeposition approach. With the increase of this molar ratio, the electrochemical performances give a volcano trend. When the optimized molar ratio is 0.64/0.36, the hybrid delivered a high specific capacitance of 1587.5 F g^(-1) at a current density of 0.5 A g^(-1), with good rate capability(1155 F g^(-1) was retained even at 10 A g^(-1)) and a robust recycle stability(remaining 91.5% after 1000 cycles at 5 A g^(-1)). The good performance could be attributed to the enlarged interlayer spacing, ultrathin nanosheets and synergistic effects between Co(OH)_2 and Ni(OH)_2. Furthermore, an asymmetric supercapacitor with a high energy density of 34.5 Wh kg^(-1) at 425 W kg^(-1) and excellent cycling stability of 85.4% after 5000 charge-discharge cycles at 2 A g^(-1) was fabricated. We believe that this fantabulous new electrode material would have encouraging applications in electrochemical energy storage and a wide readership.Min Wei Qingsong Huang Yanping Zhou Zhu Peng Wei Chu 2018Journal of Energy Chemistry2018,27,2:3

19Slow light in tapered slot photonic crystal waveguide显示文摘A slotted single-mode photonic crystal waveguide with a linear tapered slot is presented to realize slow light,whose dispersion curve is shifted by changing the slot width.When the slot width is reduced,the band curve shifts in the tapered structure,and the group velocity of light approach zero at the cut-off frequency.Therefore,different frequency components of the guided light are slowed down even localized along the propagation direction inside a tapered slot photonic crystal waveguide.Furthermore,this structure can confine slow light-wave in a narrow slot waveguide,which may effectively enhance the interaction between slow light and the low-index wave-guiding materials filled in the slot.In addition,this tapered slot structure can be used to compensate group velocity dispersion of slow light by modifying the structure,thus opening the opportunity for ultra-wide bandwidth slow light.WU Jun LI YanPing YANG ChuanChuan PENG Chao WANG ZiYu 2009Chinese Science Bulletin2009,54,20:2
20Rationally designed Ta_(3)N_(5)/BiOCl S-scheme heterojunction with oxygen vacancies for elimination of tetracycline antibiotic and Cr(Ⅵ):Performance,toxicity evaluation and mechanism insight显示文摘S-scheme heterojunction photocatalysts have been the“stars”in the field of photocatalysis.Herein,a novel S-scheme heterojunction of Ta_(3)N_(5)/BiOCl with oxygen vacancies(OVs)was fabricated via a facile method.The charge separation and transport mechanism of this Ta_(3)N_(5)/BiOCl S-scheme heterojunction was verified by the analyses of band energy structures,active species,photoelectric behaviors and DFT theoretical calculation.Compared with Ta_(3)N_(5)and BiOCl,the Ta_(3)N_(5)/BiOCl unveils substantially upgraded photocatalytic property under visible light,and the photocatalytic efficiency for removal of tetracycline(TC)and hexavalent chromium(Cr(VI))reaches 89.6%and 91.6%,respectively.The substantial enhancement of the photocatalytic activity is attributed to the synergistic effect of the S-scheme hetero-structure and oxygen vacancies,which improves the visible-light absorption,while promoting the spatial separation of charge carriers with the optimum redox capacity,thereby boosting the production of active species for catalytic reactions.The TC degradation pathway is deduced and the toxicity evolution of TC is appraised using the QSAR method.In a nutshell,this work gives a deep understanding of the photocatalytic mechanism based on Ta_(3)N_(5)/BiOCl as well as presents a newfangled thought for developing highly efficient S-scheme heterojunction photocatalysts for water decontamination.Shijie Li Mingjie Cai Chunchun Wang Yanping Liu Neng Li Peng Zhang Xin Li 2022Journal of Materials Science & Technology2022,,28:2
