2Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices.Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng 2016Light(Science & Applications)2016,5,1:36
3Sleep and Cognitive Abnormalities in Acute Minor Thalamic Infarction显示文摘In order to characterize sleep and the cognitive patterns in patients with acute minor thalamic infarction(AMTI), we enrolled 27 patients with AMTI and 12 matched healthy individuals. Questionnaires about sleep and cognition as well as polysomnography(PSG) were performed on days 14 and 90 post-stroke. Compared to healthy controls, in patients with AMTI, hyposomnia was more prevalent; sleep architecture was disrupted as indicated by decreased sleep efficiency, increased sleep latency, and decreased non-rapid eye movement sleep stages 2 and 3;more sleep-related breathing disorders occurred; and cognitive functions were worse, especially memory. While sleep apnea and long-delay memory recovered to a large extent in the patients, other sleep and cognitive function deficit often persisted. Patients with AMTI are at an increased risk for hyposomnia, sleep structure disturbance,sleep apnea, and memory deficits. Although these abnormalities improved over time, the slow and incomplete improvement suggest that early management should be considered in these patients.Wei Wu Linyang Cui Ying Fu Qianqian Tian Lei Liu Xuan Zhang Ning Du Ying Chen Zhijun Qiu Yijun Song Fu-Dong Shi Rong Xue 2016Neuroscience Bulletin2016,32,4:28

8Tongue coating microbiome as a potential biomarker for gastritis including precancerous cascade显示文摘The development of gastritis is associated with an increased risk of gastric cancer. Current invasive gastritis diagnostic methods are not suitable for monitoring progressIn this work based on 78 gastritis patients and 50 healthy individuals, we observed that the variation of tongue-coating microbiota was associated with the occurrenee and development of gastritis. Twenty-one microbial species were identified for differentiating tongue-coating microbiomes of gastritis and healthy individuals. Pathways such as microbial metabolism in diverse environments, biosynthesis of antibiotics and bacterial chemotaxis were up-regulated in gastritis patients. The abundance of Campylobacter concisus was found associated with the gastric precancerous cascade. Furthermore, Campylobacter concisus could be detected in tongue coating and gastric fluid in a validation cohort containing 38 gastritis patients. These observations provided biological evidence of tongue diagnosis in traditional Chinese medicine, and indicated that tongue-coating microbiome could be a potential non-invasive biomarker, which might be suitable for long-term monitoring of gastritis.Jiaxing Cui Hongfei Cui Mingran Yang Shiyu Du Junfeng Li Yingxue Li Liyang Liu Xuegong Zhang Shao Li 2019Protein & Cell2019,10,7:21
9Research on the cutting force of a pick显示文摘Cutting tests were done using a test bed designed to measure pick cutting forces when cutting coal and rock.The test equipment has a drum with two starting helical vanes.Cutting forces on a pick were measured as a function of coal compressive strength,pick carbide tip diameter and the cutting depth per drum revolution.The results show that the cutting force is linearly related to the compressive strength.The relationship between the cutting force and both the carbide tip diameter and the cutting depth are exponential.Fluctuation in the cutting force does not increase with coal compressive strength but it has a linear relationship to tip diameter.A plot of cutting force fluctuations versus the cutting depth follows a sigmoidal curve.Based on the analysis of these test results a theoretical basis is supplied for design and effective use of shearer drums.LIU Song-yong DU Chang-long CUI Xin-xia 2009Mining Science and Technology2009,19,4:20
10Anus-preserving rectectomy via telescopic colorectal mucosal anastomosis for low rectal cancer: Experience from a Chinese cohort显示文摘AIM: To investigate the safety and efficacy of anus-preserving rectectomy via telescopic colorectal mucosal anastomosis (TCMA) for low rectal cancer. METHODS: From August 1993 to October 2012, 420 patients including 253 males and 167 females with low rectal cancer underwent transabdominal and transanal anterior resection, followed by TCMA. The distance be-tween the anus and inferior margin of the tumor ranged from 5 to 7 cm, and was 5 cm in 6 patients, 6 cm in 127, and 7 cm in 287 patients. Tumor-node-metastasis staging showed that 136 patients had stage Ⅰ, 252 had stage Ⅱ and 32 had stage Ⅲ. Fifty-six patients with T3 or over received preoperative neoadjuvant chemoradio-therapy. RESULTS: The postoperative follow-up rate was 91.9% (386/420) with a median time of 6.4 years. All 420 pa-tients underwent radical resection. No postoperativedeath occurred. Postoperative complications included anastomotic leakage in 13 (3.1%) patients and anas-tomotic stenosis in 7 (1.6%). The local recurrence rate after surgery was 6.2%, the hepatic metastasis rate was 13.2% and the pulmonary metastasis rate was 2.3%. The 5-year survival rate was 74.0% and the disease-free survival rate was 71.0%. Kirwan classification showed that continence was good in 94.4% of patients with stage I when scored 12 mo after resection. CONCLUSION: TCMA for patients with low rectal cancer leads to better quality of life and satisfactory defecation function, and lowers anastomotic leakage occurrence, and might be one of the safe operative procedures in anus-preserving rectectomy.Shi-Yong Li Gang Chen Xue Bai Fu-Yi Zuo Guang Chen Jun-Feng Du Xiao-Jun Wei Wei Cui 2013World Journal of Gastroenterology2013,19,24:19
11Laparoscopic resection of lower rectal cancer with telescopic anastomosis without abdominal incisions显示文摘AIM:To assess laparoscopic radical resection of lower rectal cancer with telescopic anastomosis through transanal resection without abdominal incisions.METHODS:From March 2010 to June 2014, 30 patients(14 men and 16 women, aged 36-78 years, mean age 59.8 years) underwent laparoscopic radical resection of lower rectal cancer with telescopic anastomosis through anus-preserving transanal resection.The tumors were 5-7 cm away from the anal margin in 24 cases, and 4 cm in six cases.In preoperative assessment, there were 21 cases of T1N0M0 and nine of T2N0M0.Through the middle approach, the sigmoid mesentery was freed at the root with an ultrasonic scalpel and the roots of the inferior mesenteric artery and vein were dissected, clamped and cut.Following the total mesorectal excision principle, the rectum was separated until the anorectal ring reached 3-5 cm from the distal end of the tumor.For perineal surgery, a ring incision was made 2 cm above the dentate line, and sharp dissection was performed submucosally towards the superior direction, until the plane of the levator ani muscle, to transect the rectum.The rectum and distal sigmoid colon were removed together from the anus, followed by a telescopic anastomosis between the full thickness of the proximal colon and the mucosa and submucosal tissue of the rectum.RESULTS:For the present cohort of 30 cases,the mean operative time was 178 min,with an average of 13 positive lymph nodes detected.One case of postoperative anastomotic leak was observed,requiring temporary colostomy,which was closed and recovered3 mo later.The postoperative pathology showed T1-T2N0M0 in 19 cases and T2N1M0 in 11 cases.Twelve months after surgery,94.4%patients achieved anal function Kirwan grade 1,indicating that their analfunction returned to normal.The patients were followed up for 1-36 mo,with an average of 23 mo.There was no local recurrence,and 17 patients survived for>3years(with a survival rate of 100%).CONCLUSION:Laparoscopic radical resection of lower rectal cancer with telescopic anastomosis through transanal resection without abdominal incisions is safe and feasible.Shi-Yong Li Gang Chen Jun-Feng Du Guang Chen Xiao-Jun Wei Wei Cui Fu-Yi Zuo Bo Yu Xing Dong Xi-Qing Ji Qiang Yuan 2015World Journal of Gastroenterology2015,21,16:19

15ZmCOL3, a CCT gene represses flowering in maize by interfering with the circadian clock and activating expression of ZmCCT显示文摘Flowering time is a trait vital to the adaptation of flowering plants to different environments.Here, we report that CCT domain genes play an important role in flowering in maize(Zea mays L.).Among the 53 CCT family genes we identified in maize, 28 were located in flowering time quantitative trait locus regions and 15 were significantly associated with flowering time, based on candidate-gene association mapping analysis.Furthermore, a CCT gene named ZmCOL3 was shown to be a repressor of flowering.Overexpressing ZmCOL3 delayed flowering time by approximately 4 d, in either long-day or short-day conditions.The absence of one cytosine in the ZmCOL3 3'UTR and the presence of a 551 bp fragment in the promoter region are likely the causal polymorphisms contributing to the maize adaptation from tropical to temperate regions.We propose a modified model of the maize photoperiod pathway, wherein ZmCOL3 acts as an inhibitor of flowering either by transactivating transcription of ZmCCT, one of the key genes regulating maize flowering, or by interfering with the circadian clock.Minliang Jin Xiangguo Liu Wei Jia Haijun Liu Wenqiang Li Yong Peng Yanfang Du Yuebin Wang Yuejia Yin Xuehai Zhang Qing Liu Min Deng Nan Li Xiyan Cui Dongyun Hao Jianbing Yan 2018Journal of Integrative Plant Biology2018,60,6:14
16Fluid Flow and Solidification Simulation in Beam Blank Continuous Casting Process With 3D Coupled Model显示文摘Based on turbulent theory, a 3D coupled model of fluid flow and solidification was built using finite difference method and used to study the influence of superheating degree and casting speed on fluid flow and solidification, analyze the interaction between shell and molten steel, and compare the temperature distribution under different technological conditions. The results indicate that high superheating degree can lengthen the liquid-core depth and make the crack and breakout possible, so suitable superheating should be controlled within 35 ℃ according to the simulation results. Casting speed which is one of the most important technological parameters of improving production rate, should be controlled between 0.85 m/min and 1.05 m/min and the caster has great potential in the improvement of blank quality.YANG Jian-wei DU Yan-ping SHI Rong CUI Xiao-chao 2006Journal of Iron and Steel Research(International)2006,13,4:14
17Exploration of the mechanisms of Ge Gen Decoction against influenza A virus infection显示文摘Ge Gen Decoction(GGD),a Traditional Chinese Medicine prescription,is mainly used to treat infectious respiratory diseases and can relieve the symptoms of influenza A virus(IAV)infection.However,the underlying mechanism of GGD against IAV infection remains unclear.In this study,we found that GGD had moderate anti-IAV activity in vitro.GGD was more effective when given before the viral infection and targeted the viral attachment and replication stages rather than the internalization sta ge.In vivo,GGD treatment reduced the virus titers of lung tissue significantly and improved the survival rate,lung index,and pulmonary hist opathological changes in H1N1-infected mice.We observed the changes in several key immuno-related indexes in GGD administrated H1N1-infected mice with anti-IAV drug oseltamivir phosphate as the control.GGD treatment decreased the expression of TNF-αand improved Th1/Th2 immune balance to reduce the excessive immune response in H1N1-infected mice.Besides,the expression of the toll-like receptor 7 signaling pathway in H1N1-infected mice decreased after GGD treatment.Our results showed that GGD has anti-IAV activity and can modulate the immune system to relieve lung inflammation.GENG Zi-Kai LI Ya-Qun CUI Qing-Hua DU Rui-Kun TIAN Jing-Zhen 2019Chinese Journal of Natural Medicines2019,17,9:14
18Comparative pharmacokinetics of six major compounds in normal and insomnia rats after oral administration of Ziziphi Spinosae Semen aqueous extract显示文摘Ziziphi Spinosae Semen(ZSS),a traditional Chinese medicine,is used in clinics for the treatment of insomnia in China and other Asian countries.Herein,we described for the first time a comparative pharmacokinetics study of the six major compounds of ZSS in normal control(NC)and para-chlorophenylalanine(PCPA)-induced insomnia model(IM)rats that were orally administered the aqueous extract of ZSS.An ultra-high-performance liquid chromatography coupled with quadrupole orbitrap mass(UHPLC-Q-Orbitrap-MS)method was developed and validated for the simultaneous determination of coclaurine,magnoflorine,spinosin,6000-feruloylspinosin,jujuboside A(JuA),and jujuboside B(JuB)in ZSS in rat plasma.The established approach was successfully applied to a comparative pharmacokinetic study.The systemic exposures of spinosin and 6000-feruloylspinosin were decreased in the IM group compared to the NC group,while plasma clearance(CL)was significantly increased.The Tmax values of JuA and JuB in IM rats were significantly lower than those in NC rats.The T1/2 of JuA in the IM group was significantly accelerated.The pharmacokinetic parameters of coclaurine and magnoflorine were not evidently affected between the two groups.These results indicate that the pathological state of insomnia altered the plasma pharmacokinetics of spinosin,6000-feruloylspinosin,JuA,and JuB in the ZSS aqueous extract,providing an experimental basis for the role of ZSS in insomnia treatment.The comparative pharmacokinetics-based UHPLC-Q-Orbitrap-MS using full-scan mode can therefore provide a reliable and suitable means for the screening of potentially effective substances applied as quality markers of ZSS.Chenhui Du Yan Yan Chenxi Shen Xiaofang Cui Xiangping Pei Xuemei Qin 2020Journal of Pharmaceutical Analysis2020,10,4:14
19A Prospective Randomized Multicenter Controlled Trial on Salvianolate for Treatment of Unstable Angina Pectoris in A Chinese Elderly Population显示文摘Objective: To evaluate the efficacy and safety of salvianolate in elderly patients with unstable angina pectoris(UAP). Methods: A prospective double-blind randomized placebo-controlled multicenter trial in elderly patients with UAP from 13 third-grade class-A hospitals in China was performed. A total of 318 patients were randomly allocated in a 1:1 ratio to an experimental group(160 patients) and a control group(158 patients). The experimental group was treated with salvianolate for 14 days on the basis of conventional medicine, and the control group was given a placebo for 14 days with the same criteria. Follow-up was lasted 28 days in both groups. The primary endpoint was biweekly frequency of angina pectoris attacks. The secondary endpoints included biweekly dosage of nitroglycerin, the Seattle Angina Questionnaire, angina pectoris severity and duration, myocardial injury markers, high-sensitivity C-reactive protein(hs-CRP) and N-terminal pro-B-type natriuretic peptide(NT-proBNP), as well as major adverse cardiovascular events(MACEs). Safety was assessed according to adverse events and serious adverse events. Results: Baseline characteristics were similar between treatment groups. Compared with those in the control group, the frequency of biweekly angi na attacks(2.92 vs. 4.08, P =0.025), th e biweekly dosage of nitroglycerin, as well as the severity and duration of angina attacks(P <0.01) were reduced by salvianolate. The Seattle Angina Questionnaire score was also significantly improved in the experimental group than in the control group(P <0.05). No significant differences were observed between the two groups with respect to the incidence of MACEs. Salvianolate was well tolerated. Conclusions: Salvianolate appear to have efficacy and well tolerated for elderly patients with UAP.CUI Hua LI Xiao-ying GAO Xue-wen LU Xiang WU Xiu-ping WANG Xiao-fei ZHENG Xiang-qing HUANG Kui LIU Feng LUO Zhi YUAN Hui-shu SUN Gang KONG Jian DU Xiao-hong ZHENG Jin LIU Hong-ying ZHANG Wen-ju 2019Chinese Journal of Integrative Medicine2019,25,10:13
20Study on pick arrangement of shearer drum based on load fluctuation显示文摘According to the coal or rock cutting theory,a mechanical model and computing formula for a pick and the drum load fluctuation model were established in order to obtain relationships between pick arrangements and drum fluctuation loads,drum rotary speeds and haulage speeds.Based on a minimum load fluctuation,an optimal mathematical model was established for drum pick arrangements.The effects of pick arrangements(including punnett square,sequence,aberrance I and II)on the drum load fluctuation coefficient are discussed.The relationships between the pick arrangements of the drum with different start vanes and the cutting load fluctuation coefficient,the drum rotary speed and haulage speed were also studied.The results indicate that the punnett square arrangement has a smaller cutting load fluctuation coefficient than other forms of arrangement and the drum with the 4-start vanes has the smallest coefficient.The drum rotary speed and haulage speed are affected not only by pick arrangements,but also by the number of vanes.DU Chang-long LIU Song-yong CUI Xin-xia LI Ti-jian 2008Journal of China University of Mining and Technology2008,18,2:12
