1Control of Grain Size and Weight by the OsMKKK10-OsM KK4-OsMAPK6 Signaling Pathway in Rice显示文摘谷物尺寸是在庄稼决定谷物产量的关键农学的特点之一。然而,在庄稼位于谷物尺寸控制下面的机制留下逃犯。这里,我们证明断然表明小径的 OsMKKK10-OsMKK4-OsMAPK6 在米饭调整谷物尺寸和重量。在米饭,当组成地活跃的 OsMKKK10 (CA-OsMKKK10 ) 的 overexpression 导致大、重的谷物,长圆锥花序,和高植物时, OsMKKK10 功能的损失导致小、轻的谷物,短圆锥花序,和半矮子植物。OsMKKK10 交往与并且 phosphorylates OsMKK4。我们识别了 OsMKK4 gain-of-function 异种(large11-1D )? 那生产大、重的谷物。OsMKK4 large11-1D 等位基因编码的 A227T 比 OsMKK4 举办更强壮的 kinase 活动。植物 overexpressing OsMKK4 (OsMKK4-DD ) 的一种组成地活跃的形式也生产大谷物。进一步生物化学、基因的分析表明 OsMKKK10, OsMKK4,和 OsMAPK6 在一条普通小径工作控制谷物尺寸。一起拿,我们的学习在米饭为谷物尺寸和重量的 OsMKKK10-OsMKK4-OsMAPK6 调停串联的控制建立一个重要基因、分子的框架。Ran Xu Penggen Duan Haiyue Yu Zhengkui Zhou Baolan Zhang Ruci Wang Jing Li Guozheng Zhang Shangshang Zhuang Jia Lyu Na Li Tuanyao Chai Zhixi Tian Shanguo Yao Yunhai Li 2018Molecular Plant2018,11,6:33
2Effect of polyglycolic acid sheet plus esophageal stent placement in preventing esophageal stricture after endoscopic submucosal dissection in patients with earlystage esophageal cancer: A randomized, controlled trial显示文摘AIM To assess the effect of polyglycolic acid(PGA) plus stent placement compared with stent placement alone in the prevention of post-endoscopic submucosal dissection(ESD) esophageal stricture in early-stage esophageal cancer(EC) patients. METHODS Seventy EC patients undergoing ESD were enrolled in this randomized, controlled study. Patients were allocated randomly at a 1:1 ratio into two groups as follows:(1) PGA plus stent group(PGA sheet-coated stent placement was performed); and(2) Stent group(only stent placement was performed). This study was registered on http://gffzz62a03ee25e6f4a77hwqfn6vvbwp5p695v.ffgz.tsg.suse.edu.cn(No. chictrinr-16008709). RESULTS The occurrence rate of esophageal stricture in the PGA plus stent group was 20.5%(n = 7), which was lower than that in the stent group(46.9%, n = 15)(P = 0.024). The mean value of esophageal stricture time was 59.6 ± 16.1 d and 70.7 ± 28.6 d in the PGA plus stent group and stent group(P = 0.174), respectively. Times of balloon dilatation in the PGA plus stent group were less than those in the stent group [4(2-5) vs 6(1-14), P = 0.007]. The length(P = 0.080) and diameter(P = 0.061) of esophageal strictures were numerically decreased in the PGA plus stent group, whereas no difference in location(P = 0.232) between the two groups was found. Multivariate logistic analysis suggested that PGA plus stent placement(P = 0.026) was an independent predictive factor for a lower risk of esophageal stricture, while location in the middle third(P = 0.034) and circumferential range = 1/1(P = 0.028) could independently predict a higher risk of esophageal stricture in EC patients after ESD. CONCLUSION PGA plus stent placement is more effective in preventing post-ESD esophageal stricture compared with stent placement alone in EC patients with earlystage disease.Ning-Li Chai Jia Feng Long-Song Li Sheng-Zhen Liu Chen Du Qi Zhang En-Qiang Linghu 2018World Journal of Gastroenterology2018,24,9:24

6Pretreatment with Danhong injection protects the brain against ischemia-reperfusion injury显示文摘Danhong injection(DHI),a Chinese Materia Medica standardized product extracted from Radix Salviae miltiorrhizae and Flos Carthami tinctorii,is widely used in China for treating acute ischemic stroke.In the present study,we explored the neuroprotective efficacy of DHI in a rat model of temporary middle cerebral artery occlusion,and evaluated the potential mechanisms underlying its effects.Pretreatment with DHI(0.9 and 1.8 mL/kg)resulted in a significantly smaller infarct volume and better neurological scores than pretreatment with saline.Furthermore,DHI significantly reduced the permeability of the blood-brain barrier,increased occludin protein expression and decreased neutrophil infiltration,as well as profoundly suppressing the upregulation of matrix metallopeptidase-9 expression seen in rats that had received vehicle.Matrix metallopeptidase-2 expression was not affected by ischemia or DHI.Moreover,DHI(1.8 mL/kg)administered 3 hours after the onset of ischemia also improved neurological scores and reduced infarct size.Our results indicate that the neuroprotective efficacy of DHI in a rat model of cerebral ischemia-reperfusion injury is mediated by a protective effect on the blood-brain barrier and the reversal of neutrophil infiltration.Shaoxia Wang Hong Guo Xumei Wang Lijuan Chai Limin Hu Tao Zhao Buchang Zhao Xiaoxu Tan Feifei Jia 2014Neural Regeneration Research2014,9,15:12
7Homoeologous cloning of ω-secalin gene family in a wheat 1BL/1RS translocation显示文摘Wheat 1BL/1RS translocations are widely planted in China as well as in most of the wheat producing area in the world for their good qualities of disease resistance and high yield. 1BL/1RS translocations are however poor in bread making, partially caused by a family of small monomeric proteins, ω-secalins, which are encoded by genes on 1RS. Based on published sequence of a rye ω-secalin gene we designed a pair of primers to cover the whole mature protein coding sequence. A major band could be amplified from 1BL/1RS translocations but not from euploid wheat. Using this primer set we conducted PCR amplification by using high fidelity Pfu polymerase on the genomic DNAs and cDNAs purified from a 1BL/1RS translocation Lankao 906. Sequencing analysis indicated that this gene family contains several mem- bers of 1150 bp, 1076 bp, 1075 bp, 1052 bp and 1004 bp genes, including two pseudogenes and three active genes. The gene transcripts were differentially expressed in developing seeds.Jian Fang CHAI Xu LIU Ji Zeng JIA 2005Cell Research2005,15,8:10

9Construction of an anchoring SSR marker genetic linkage map and detection of a sex-linked region in two dioecious populations of red bayberry显示文摘Red bayberry(Morella rubra)is an evergreen fruit tree found in southern China whose whole-genome sequence has recently been published.We updated the linkage map of the species by adding 118 SSR markers and the femalespecific marker MrFT2_BD-SEX.The integrated map included eight linkage groups and spanned 491 cM.Eleven sexassociated markers were identified,six of which were located in linkage group 8,in agreement with the previously reported location of the sex-determining region.The MrFT2_BD-SEX marker was genotyped in 203 cultivated accessions.Among the females of the accessions,we found two female-specific alleles,designated W-b(151 bp)and W-d(129 bp).We previously found that‘Dongkui’,a female cultivar,could produce viable pollen(we refer to such plants‘Dongkui-male’)and serve as the paternal parent in crosses.The genotypes of the MrFT2_BD-SEX marker were W-b/Z in‘Biqi’and W-d/Z in‘Dongkui-male’.The progeny of a cross between these parents produced a 3:1 female(W-)to male(ZZ)ratio and the expected 1:1:1:1 ratio of W-b/W-d:W-b/Z:W-d/Z:Z/Z.In addition,the flowering and fruiting phenotypes of all the F1 progeny fit their genotypes.Our results confirm the existence of ZW sex determination and show that the female phenotype is controlled by a single dominant locus(W)in a small genomic region(59 kb and less than 3.3 cM).Furthermore,we have produced a homozygous“super female”(WW)that should produce all-female offspring in the F2 generation,providing a foundation for commercial use and presenting great potential for use in modern breeding programs.Yan Wang Hui-Min Jia Yu-Tong Shen Hai-Bo Zhao Qin-Song Yang Chang-Qing Zhu De-Li Sun Guo-Yun Wang Chao-Chao Zhou Yun Jiao Chun-Yan Chai Li-Ju Yan Xiong-Wei Li Hui-Juan Jia Zhong-Shan Gao 2020Horticulture Research2020,7,1:10
10Status of study on biological and toxicological effects of nanoscale materials显示文摘Because the physical and chemical properties of nanosized materials mostly differ from the existing microsized materials, their potential impacts on human health and the envi-ronment will be topics under the serious discussions in press and in a number of international scientific journals. We analyze and summarize the existing data of the experimental study on the biological activities and adverse effects of nanoscale materials/particles including single wall carbon nanotubes, multi wall carbon nanotubes, titanium oxide and iron powders. Though some biological behaviors of nanoscale materials observed cannot be understood on the basis of the current knowledge, as the existing data are mostly preliminary, it is too early to make some ex-clusive conclusions on biological activities (or the toxicity) of any of nanoscale materials. The experimental techniques, the current topics, and the future research directions for this new re-search field are also discussed.WANG Bing1, FENG Weiyue1, ZHAO Yuliang1, XING Gengmei1, CHAI Zhifang1, WANG Haifang2 & JIA Guang3 1.

11A natural variation in Ribonuclease H-like gene underlies Rht8 to confer“Green Revolution”trait in wheat显示文摘Dear Editor,Introduction of gibberellin(GA)-insensitive Reduced height(Rht)genes,Rht-B1b and Rht-D1b,has resulted in the“Green Revolution”in modern wheat cultivars(Triticum aestivum)that has skyrocketed wheat grain yields worldwide since the 1960s(Peng et al.,1999;Velde et al.,2021).However,Rht-B1b/D1b also reduce coleoptiles,which is undesired in dryland regions where deep planting is essential for seedling establishment(Rebetzke et al.,1999,Rebetzke et al.,2001;Ellis et al.,2004).Lingling Chai Mingming Xin Chaoqun Dong Zhaoyan Chen Huijie Zhai Junhong Zhuang Xuejiao Cheng Naijiao Wang Jia Geng Xiaobo Wang Ruolin Bian Yingyin Yao Weilong Guo Zhaorong Hu Huiru Peng Guihua Bai Qixin Sun Zhenqi Su Jie Liu Zhongfu Ni 2022Molecular Plant2022,15,3:8
12Effect of the distributor plugging ways on fluidization quality and particle stratification in air dense medium fluidized bed显示文摘Gas-solid fluidized bed separation is a highly efficient and clean technique for coal separation,and can effectively remove ash and sulfur contained gangue minerals from coal.However,the fine coal plugging distributor often leads to uneven fluidization and affects the separation effect.In this paper,different plugging ways were designed to study their effects on the fluidization characteristics and particle mixing.It was found that when the plugging phenomenon occurs,the minimum fluidization velocity of the fluidized bed gradually decreases as the plugging area enlarges.The difference between the top and the bottom of the bed minimum fluidization velocity increases accordingly,and a“stagnation phenomenon”occurs in the bed.The standard deviation of pressure fluctuations at the top of the bed is smaller than that at the bottom of the bed,which is the opposite of normal conditions.As the area of the plugging increases,the dead zone on the side wall of the fluidized bed significantly increases.The size of the dead zone is rapid reducing at the initial stage.It was noticed that the stratification of the low-density products is particularly affected by plugging,whereas the stratification of high-density products is not obviously influenced by certain conditions.Zhonglin Gao Xuesen Chai Enhui Zhou Ying Jia Chenlong Duan Ligang Tang 2020International Journal of Mining Science and Technology2020,30,6:7

14Real world effectiveness of PCSK-9 inhibitors combined with statins versus statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease in China(RWE-PCSK study)显示文摘BACKGROUND The efficacy and safety of proprotein convertase subtilisin/kexin type 9(PCSK-9) inhibitors were confirmed by several clinical trials, but its effectiveness in routine clinical practice in China has not been evaluated. This study aims to describe the real world effectiveness of PCSK-9 inhibitors combined with statins compared with statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease(ASCVD).METHODS This is a multi-center observational study, enrolled patients from 32 hospitals who underwent percutaneous coronary intervention(PCI) from January to June in 2019. There are 453 patients treated with PCSK-9 inhibitors combined with statins in PCSK-9 inhibitor group and 2,610 patients treated with statins-based lipid lowering therapies in statins-based group. The lipid control rate and incidence of major adverse cardiovascular events(MACE) over six months were compared between two groups.A propensity score-matched(PSM) analysis was used to balance two groups on confounding factors. Survival analysis using Kaplan-Meier methods was applied for MACE.RESULTS In a total of 3,063 patients, 89.91% of patients had received moderate or high-intensity statins-based therapy before PCI, but only 9.47% of patients had low-density lipoprotein cholesterol(LDL-C) levels below 1.4 mmol/L at baseline. In the PSM selected patients, LDL-C level was reduced by 42.57% in PCSK-9 inhibitor group and 30.81%(P < 0.001) in statins-based group after six months. The proportion of LDL-C ≤ 1.0 mmol/L increased from 5.29% to 29.26% in PCSK-9 inhibitor group and 0.23% to 6.11% in statins-based group, and the proportion of LDL-C ≤ 1.4 mmol/L increased from 10.36% to 47.69% in PCSK-9 inhibitor group and 2.99% to 18.43% in statins-based group(P < 0.001 for both). There was no significant difference between PCSK-9 inhibitor and statins-based treatment in reducing the risk of MACE(hazard ratio = 2.52, 95% CI: 0.49-12.97, P = 0.250).CONCLUSIONS In the real world, PCSK-9 inhibitors combined with statins could significantly reduce LDL-C levels among patients with very high risk of ASCVD in China. The long-term clinical benefits for patients received PCSK-9 inhibitor to reduce the risk of MACE is still unclear and requires further study.Yu-Qi LIU Dan-Dan LI Meng CHAI Hong-Liang CONG Xiao-Qiang CONG Jun DAI Rong-Pin DU Ming GAO Jin-Cheng GUO Yan-Qing GUO Xiao-Jian HONG Rong-Chong HUANG Feng-Shun JIA Jia-Yu LI Qing LI Jia-Mei LIU Xin-Ping LIU Yu-Guo LIU Hong-Gang NIE Bing SHAO Xiao-Yu SHEN Hai-Qing SONG Yi-Jun SONG Li-Jun WANG Shuo WANG Dong-Mei WU Jing XIA Zhi-Yong YANG Hong-Ying YU Hui ZHANG Tie-Mei ZHANG Ji-Yi ZHAO Liang-Chen ZHAO Ming-Qi ZHENG Yun-Dai CHEN 2021Journal of Geriatric Cardiology2021,18,4:5
15Periodontal status and associated risk factors among childbearing age women in Cixi City of China显示文摘Objective:To investigate the periodontal status and associated risk factors among women of childbearing age to increase the awareness of oral health.Methods:The study was conducted on childbearing age women in Cixi,a city in Zhejiang Province in the southeast of China.A total of 754 women participated in periodontal examination while receiving prenatal care.Data of the women were collected from the Cixi Family Planning Commission and during an interview.Clinical periodontal indices,such as bleeding on probing(BOP),probing depth(PD),and clinical attachment level(CAL) were measured during the examination.Statistical analysis on subject-based data was performed.Results:The prevalence of periodontal disease among childbearing age women in Cixi was high(84.7%).A significant association was found between the disease and educational level,pregnancy,taking oral contraceptives,stress,alcohol consumption,overweight,dental visit,and teeth brushing(P<0.05).Women who suffered periodontal disease showed deep PD,obvious BOP,and clinical attachment loss.Among this population,pregnancy was closely associated with higher BOP percentage;teeth brushing no more than once per day or brushing for less than 1 min(P<0.001) after adjusting for age and stress.Conclusions:The periodontal status of childbearing age women in Cixi needs to be improved urgently.Attention towards the periodontal health should be warranted,especially for those in special statuses and with poor awareness.Yan-min WU Jia LIU Wei-lian SUN Li-li CHEN Li-guo CHAI Xiang XIAO Zheng CAO 2013Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013,14,3:4
16Cardioprotective mechanisms of salvianic acid A sodium in rats with myocardial infarction based on proteome and transcriptome analysis显示文摘Ischemic heart diseases(IHDs)cause great morbidity and mortality worldwide,necessitating effective treatment.Salvianic acid A sodium(SAAS)is an active compound derived from the well-known herbal medicine Danshen,which has been widely used for clinical treatment of cardiovascular diseases in China.This study aimed to confirm the cardioprotective effects of SAAS in rats with myocardial infarction and to investigate the underlying molecular mechanisms based on proteome and transcriptome profiling of myocardial tissue.The results showed that SAAS effectively protected against myocardial injury and improved cardiac function.The differentially expressed proteins and genes included important structural molecules,receptors,transcription factors,and cofactors.Functional enrichment analysis indicated that SAAS participated in the regulation of actin cytoskeleton,phagosome,focal adhesion,tight junction,apoptosis,MAPK signaling,and Wnt signaling pathways,which are closely related to cardiovascular diseases.SAAS may exert its cardioprotective effect by targeting multiple pathways at both the proteome and transcriptome levels.This study has provided not only new insights into the pathogenesis of myocardial infarction but also a road map of the cardioprotective molecular mechanisms of SAAS,which may provide pharmacological evidence to aid in its clinical application.Dan Jia Cheng-zhong Zhang Yan Qiu Xiao-fei Chen Lin Jia Alex F.Chen Yi-feng Chai Zhen-yu Zhu Jin Huang Chuan Zhang 2019Acta Pharmacologica Sinica2019,40,12:4
17Identification of Nonstructural Protein 8 as the N-Terminus of the RNA-Dependent RNA Polymerase of Porcine Reproductive and Respiratory Syndrome Virus显示文摘Porcine reproductive and respiratory syndrome virus (PRRSV) is a member within the family Arteriviridae of the order Nidovirales. Replication of this positive-stranded RNA virus within the host cell involves expression of viral replicase proteins encoded by two ORFs, namely ORF1 a and ORF1 b. In particular, translation of ORF1 b depends on a-1-ribosomal frameshift strategy. Thus, nonstructural protein 9 (nsp9), the first protein within ORF1 b that specifies the function of the viral RNA-dependent RNA polymerase, is expressed as the C-terminal extension of nsp8, a small nsp that is encoded by ORF1 a. However, it has remained unclear whether the mature form of nsp9 in virus-infected cells still retains nsp8,addressing which is clearly critical to understand the biological function of nsp9. By taking advantage of specific antibodies to both nsp8 and nsp9, we report the following findings. (1) In infected cells, PRRSV nsp9 was identified as a major product with a size between 72 and 95 k Da (72–95 KDa form), which exhibited the similar mobility on the gel to the in vitro expressed nsp8–9 ORF1 b, but not the ORF1 b-coded portion (nsp9 ORF1 b). (2) The antibodies to nsp8, but not to nsp7 or nsp10, could detect a major product that had the similar mobility to the 72–95 KDa form of nsp9. Moreover, nsp9 could be co-immunoprecipitated by antibodies to nsp8, and vice versa. (3) Neither nsp4 nor nsp2 PLP2 was able to cleave nsp8–nsp9 in vitro. Together, our studies provide experimental evidence to suggest that nsp8 is an N-terminal extension of nsp9.Our findings here paves way for further charactering the biological function of PRRSV nsp9.Yuanyuan Liu Yunhao Hu Yue Chai Liping Liu Jiangwei Song Shaochuan Zhou Jia Su Lei Zhou Xinna Ge Xin Guo Jun Han Hanchun Yang 2018Virologica Sinica2018,33,5:3
