| 2 | Dual gRNAs guided CRISPR/Cas9 system inhibits hepatitis B virus replication显示文摘AIM: To screen and investigate the effective g RNAs against hepatitis B virus(HBV) of genotypes A-D.METHODS: A total of 15 g RNAs against HBV of genotypes A-D were designed. Eleven combinations of two above g RNAs(dual-g RNAs) covering the regulatory region of HBV were chosen. The efficiency of each g RNA and 11 dual-g RNAs on the suppression of HBV(genotypes A-D) replication was examined by the measurement of HBV surface antigen(HBs Ag) or e antigen(HBe Ag) in the culture supernatant. The destruction of HBV-expressing vector was examined in Hu H7 cells co-transfected with dual-g RNAs and HBVexpressing vector using polymerase chain reaction(PCR) and sequencing method, and the destruction of ccc DNAwas examined in Hep AD38 cells using KCl precipitation, plasmid-safe ATP-dependent DNase(PSAD) digestion, rolling circle amplification and quantitative PCR combined method. The cytotoxicity of these g RNAs was assessed by a mitochondrial tetrazolium assay.RESULTS: All of g RNAs could significantly reduce HBs Ag or HBe Ag production in the culture supernatant, which was dependent on the region in which g RNA against. All of dual g RNAs could efficiently suppress HBs Ag and/or HBe Ag production for HBV of genotypes A-D, and the efficacy of dual g RNAs in suppressing HBs Ag and/or HBe Ag production was significantly increased when compared to the single g RNA used alone. Furthermore, by PCR direct sequencing we confirmed that these dual g RNAs could specifically destroy HBV expressing template by removing the fragment between the cleavage sites of the two used g RNAs. Most importantly, g RNA-5 and g RNA-12 combination not only could efficiently suppressing HBs Ag and/or HBe Ag production, but also destroy the ccc DNA reservoirs in Hep AD38 cells.CONCLUSION: These results suggested that CRISPR/Cas9 system could efficiently destroy HBV expressing templates(genotypes A-D) without apparent cytotoxicity. It may be a potential approach for eradication of persistent HBV ccc DNA in chronic HBV infection patients. | Jie Wang Zhong-Wei Xu Shuang Liu Rui-Yang Zhang Shan-Long Ding Xiao-Meng Xie Lu Long Xiang-Mei Chen Hui Zhuang Feng-Min Lu | 2015 | World Journal of Gastroenterology2015，21，32： | 29 |

| 5 | Nomogram to predict overall survival after gallbladder cancer resection in China显示文摘AIM To integrate clinically significant variables related to prognosis after curative resection for gallbladder carcinoma(GBC) into a predictive nomogram.METHODS One hundred and forty-two GBC patients who underwent curative intent surgical resection at Peking Union Medical College Hospital(PUMCH) were included. This retrospective case study was conducted at PUMCH of the Chinese Academy of Medical Sciences and Peking Union Medical College(CAMS & PUMC) in China from January 1, 2003 to January 1, 2018. The continuous variable carbohydrate antigen 19-9(CA19-9) was converted into a categorical variable(cCA19-9) based on the normal reference range. Stages 0 to IIIA were merged into one category, while the remaining stages were grouped into another category. Pathological grade X(GX) was treated as a missing value. A multivariate Cox proportional hazards model was used to select variables to construct a nomogram. Discrimination and calibration of the nomogram were performed via the concordance index(C-index) and calibration plots. The performance of the nomogram was estimated using the calibration curve. Receiver operating characteristic(ROC) curve analysis and decision curve analysis(DCA) were performed to evaluate the predictive accuracy and net benefit of the nomogram, respectively.RESULTS Of these 142 GBC patients, 55(38.7%) were male, and the median and mean age were 64 and 63.9 years, respectively. Forty-eight(33.8%) patients in this cohort were censored in the survival analysis. The median survival time was 20 months. A series of methods, including the likelihood ratio test and Akaike information criterion(AIC) as well as stepwise, forward, and backward analyses, were used to select the model, and all yielded identical results. Jaundice [hazard ratio(HR) = 2.9; 95% confidence interval(CI): 1.60-5.27], cCA19-9(HR = 3.2; 95%CI: 1.91-5.39), stage(HR = 1.89; 95%CI: 1.16-3.09), and resection(R)(HR = 2.82; 95%CI: 1.54-5.16) were selected as significant predictors and combined into a survival time predictive nomogram(C-index = 0.803; 95%CI: 0.766-0.839). High prediction accuracy(adjusted C-index = 0.797) was further verified via bootstrap validation. The calibration plot demonstrated good performance of the nomogram. ROC curve analysis revealed a high sensitivity and specificity. A high net benefit was proven by DCA.CONCLUSION A nomogram has been constructed to predict the overall survival of GBC patients who underwent radical surgery from a clinical database of GBC at PUMCH. | Yi Bai Zhi-Song Liu Jian-Ping Xiong Wei-Yu Xu Jian-Zhen Lin Jun-Yu Long Fei Miao Han-Chun Huang Xue-Shuai Wan Hai-Tao Zhao | 2018 | World Journal of Gastroenterology2018，24，45： | 25 |
| 6 | Prognostic significance of combined preoperative fibrinogen and CA199 in gallbladder cancer patients显示文摘AIM To investigate the prognostic value of the combination of preoperative plasma fibrinogen and CA199 in patients with gallbladder carcinoma(GBC).METHODS The clinicopathological data of 154 GBC patients were retrospectively reviewed after surgery. A receiver operating characteristic(ROC) curve was plotted to verify the optimum cut-off values for plasma fibrinogen and CA199. Univariate and multivariate survival analyses were performed to identify the factors associated with GBC prognosis. based on the HRs calculated via multivariate survival analyses, patients with elevated plasma fibrinogen and CA199 levels were allocated a score of 2.1; those with an elevated plasma fibrinogen level only were allocated a score of 1, those with an elevated CA199 level only were allocated a score of 1.1, and those with neither of these abnormalities were allocated a score of 0.RESULTS ROC curve analysis showed that the optimum cut-off values for preoperative plasma fibrinogen and CA199 were 3.47 g/L and 25.45 U/mL, respectively. Multivariate analysis indicated that elevated preoperative plasma fibrinogen and CA199 levels were significantly correlated with worse overall survival(OS)(HR = 1.711, 95%CI: 1.114-2.627, P = 0.014, and HR = 1.842, 95%CI: 1.111-3.056, P = 0.018). When we combined these two parameters, the area under the ROC curve increased from 0.735(for preoperative plasma fibrinogen only) and 0.729(for preoperative CA199 only) to 0.765. When this combined variable was added to the multivariate analysis, the combination of plasma fibrinogen and CA199(P < 0.001), resection margin(P < 0.001) and TNM stage(P = 0.010) were independent prognostic factors for GBC.CONCLUSION The combination of plasma fibrinogen and CA199 may serve as a more efficient independent prognostic biomarker for postoperative GBC patients than either parameter alone. | Wei-Yu Xu Hao-Hai Zhang Xiao-Bo Yang Yi Bai Jian-Zhen Lin Jun-Yu Long Jian-Ping Xiong Jun-Wei Zhang Xin-Ting Sang Hai-Tao Zhao | 2018 | World Journal of Gastroenterology2018，24，13： | 24 |
| 7 | A New Kind of Pilot Controlled Proportional Direction Valve with Internal Flow Feedback显示文摘Proportional direction valve is one of the most fundamental elements in electronic-hydraulic control technique. Its function is to control the operating speed, direction, position, and strength of output force of the hydraulic actuator continuously. Considering the different application and the cost, the existing technique mainly includes the internal feedback valve used in open loop system, and the electronic closed loop controlled valve used in closed loop system. Because of their different mechanical structure and the great different in performance, it brings inconvenience for customer to select, also inconvenience for enterprise to produce. Aiming at this problem, the idea of combining the above two kinds of valves into one body is proposed first, and then the new valve’s structure to realize this target is designed. The idea intends to apply the displacement pilot flow feedback control principle in present 2-position 2-way valve system to the proportional direction valve of 3-position 4-way system. Newly designed feed forward controller can decouple the interference between the internal feedback and the electronic closed loop. Redundant conversion is designed to electronic switch mode. Experiment on dynamic and static characteristic of new proportional direction valve in internal feedback control mode and electronic closed loop control mode is discussed to prove the new theory is correct. Although the new valve is of excellent dynamic response characteristic, its steady control characteristic in open loop control mode needs to be improved further. The research results prepare one new fundamental element for electronic-hydraulic control technology. | QUAN Long XU Xiaoqing YAN Zheng ZHANG Xiaojun | 2010 | Chinese Journal of Mechanical Engineering2010，23，1： | 22 |
| 8 | Large-scale wind turbine blade design and aerodynamic analysis显示文摘Incorporating controlled elitism and dynamic distance crowding strategies, a modified NSGA-II algorithm based on a fast and genetic non-dominated sorting algorithm is developed with the aim of obtaining a novel multi-objective optimization design algorithm for wind turbine blades. As an example, a high-performance 1.5 MW wind turbine blade, taking maximum annual energy production and minimum blade mass as the optimization objectives, was designed. A 1/16-scale model of this blade was tested in a 12 m × 16 m wind tunnel and the experimental results validated the high performance. Moreover, both the computational fluid dynamics (CFD) method and a free-vortex method (FVM) were applied to calculating the aerodynamic performance, which was consistent with the experimental data. For completeness, the CFD and FVM were used to analyze the wake structure, and good and consistent results were obtained between them. | WANG TongGuang WANG Long ZHONG Wei XU BoFeng CHEN Li | 2012 | Chinese Science Bulletin2012，57，5： | 23 |
| 9 | Analysis of the Results of Two Nationwide Surveys on Clonorchis sinensis Infection in China显示文摘Objective To examine Clonorchis sinensis infection in China and evaluate the effectiveness of efforts to prevent and control it,two nationwide surveys were undertaken in 31 provinces,autonomous regions,and municipalities(PAMs) during 1988-92(the 1990 survey) and during 2001-04(the 2003 survey).Methods During the period 2001-04,two sampling methods were applied.The first method repeated the stratified cluster random sampling used in the 1990 survey;the second method applied two-characteristic stratified cluster random sampling in 27 PAMs-the 2003 endemic area(EA) survey.The Kato-Katz thick smear method was used for the nationwide survey.Results The infection rates of Clonorchis sinensis in the 1990 and 2003 surveys were 0.311% and 0.579%,respectively.The infection rate was 2.40% in the 2003 EA survey,and it was estimated that 12.49 million people in China were infected with Clonorchis sinensis.Conclusion The 2003 survey showed that the standardized infection rate of Clonorchis sinensis increased by 74.85% compared with the 1990 survey.The infection rate in males was higher than in females;the infection rate among people eating raw fish or eating out frequently was higher than among those who did not. | CHEN Ying Dan ZHOU Chang Hai XU Long Qi | 2012 | Biomedical and Environmental Sciences2012，25，2： | 22 |

| 11 | Protective effects of Yindanxinnaotong capsule in a rat model of myocardial ischemia/reperfusion injury显示文摘OBJECTIVE: To investigate the effects of Yindanxinnaotong capsule(YDXNTC) and main components compatibility and ratios on myocardium against ischemia/reperfusion injury and the effect's underlying mechanism.METHODS: Myocardial ischemia/reperfusion injury(MIRI) was induced by ischemia for 30 min and reperfusion for 30 min. Electrocardiogram data and coronary flow were recorded, and superoxide dismutase(SOD), malondialdehyde(MDA), lactate dehydrogenase, creatine kinase-MB, cardiac troponin T and I(cT nT, cT n I) and interleukin-1β, interleukin-8,interleukin-18(IL-1β, IL-8, IL-18) in myocardium were measured. Hypoxia/reoxygenation and hydrogen peroxide(H2O2) injury were induced by hypoxia for 3 h/reoxygenation for 2 h, and 100 μM H2O2 for 1 h, respectively, in vitro rat myocardial cells(H9c2). Cell viability, SOD, MDA, cT nT and inflamma-tory factors(IL-1β, IL-8 and IL-18) were determined,and Toll-like receptor 4(TLR-4) expression was measured by western blotting.RESULTS: In the isolated heart experiment, elevated heart function, coronary flow and SOD levels,and decreased MDA levels and inflammatory factors were noted in the YDXNTC, main components and main components compatibility groups. Ventricular tachycardia/ventricular fibrillation occurrence decreased in the ginkgo biloba extract(GBE),and GBE and salvia miltiorrhiza ethanol extract compatibility(SM-E, GSEC) groups. Lactic dehydrogenase levels decreased in the YDXNTC and aqueous extract of salvia miltiorrhiza(SM-H) groups. Creatine kinase-MB decreased with GBE, SM-E, SM-H and GSEC treatment, and cT n I and cT nT levels decreased with GSEC. In the in vitro cell study,YDXNTC and main components ratios improved cell viability and SOD levels, and suppressed MDA,cT nT and inflammatory factors. TLR-4 expression was down-regulated.CONCLUSION: YDXNTC and main components compatibility showed protective effects on MIRI in this rat model and in vitro study. Regulating the Toll-like receptor signaling pathway may affect the mechanism. | Wandan Wang Lan Wang Hongjun Yang Jianlu Wang Xiaojie Yin Haiyu Xu Long Cheng Rixin Liang | 2014 | Journal of Traditional Chinese Medicine2014，34，6： | 22 |

| 13 | Prognostic significance of the fibrinogen-to-albumin ratio in gallbladder cancer patients显示文摘AIM To investigate the prognostic role of fibrinogen-toalbumin ratio(FAR) on patients with gallbladder cancer(Gbc) in this study.METHODS One hundred and fifty-four Gbc patients were retro-spectively analyzed, who received potentially curative cholecystectomy in our institute from March 2005 to December 2017. Receiver operating characteristic curve(ROc curve) was used to determine the optimal cut-offs for these biomarkers. In addition, Kaplan-Meier survival analysis as well as multivariate analysis were applied for prognostic analyses.RESULTS ROc curve revealed that the optimal cut-off value for FAR was 0.08. FAR was significantly correlated with age(P = 0.045), jaundice(P < 0.001), differentiation(P = 0.002), resection margin status(P < 0.001), T stage(P < 0.001), TNM stage(P < 0.001), and c A199(P < 0.001) as well as albumin levels(P < 0.001). Multivariate analysis indicated that the resection margin status [hazard ratio(HR): 2.343, 95% confidence interval(c I): 1.532-3.581, P < 0.001], TNM stage(P = 0.035), albumin level(HR = 0.595, 95%c I: 0.385-0.921, P = 0.020) and FAR(HR: 2.813, 95%c I: 1.765-4.484, P < 0.001) were independent prognostic factors in Gbc patients.CONCLUSION An elevated preoperative FAR was significantly correlated with unfavorable overall survival in Gbc patients, while an elevated preoperative albumin level was a protective prognostic factor for patients with Gbc. The preoperative FAR could be used to predict the prognosis of Gbc patients, which was easily accessible, costeffective and noninvasive. | Wei-Yu Xu Hao-Hai Zhang Jian-Ping Xiong Xiao-bo Yang Yi bai Jian-Zhen Lin Jun-Yu Long Yong-chang Zheng Hai-Tao Zhao Xin-Ting Sang | 2018 | World Journal of Gastroenterology2018，24，29： | 23 |
| 14 | Efficient production of omega-3 fatty acid desaturase (sFat-1)-transgenic pigs by somatic cell nuclear transfer显示文摘Omega-3(ω-3) fatty acid desaturase transgenic pigs may improve carcass fatty acid composition. The use of transgenic pigs is also an excellent large animal model for studying the role of ω-3 fatty acids in the prevention and treatment of coronary heart disease and cancer. Transgenic pigs carrying synthesized fatty acid desaturase-1 gene (sFat-1) from Caenorhabditis briggsae by somatic cell nuclear transfer (SCNT) were produced for the first time in China. Porcine fetal fibroblast cells were transfected with a sFat-1 expression cassette by the liposome-mediated method. Transgenic embryos were reconstructed by nuclear transfer of positive cells into enucleated in vitro matured oocytes. A total of 1889 reconstructed embryos were transferred into 10 naturally cycling gilts. Nine early pregnancies were established, 7 of which went to term. Twenty-one piglets were born. The cloning efficiency was 1.1% (born piglets/transferred embryos). The integration of the sFat-1 gene was confirmed in 15 live cloned piglets by PCR and Southern blot except for 2 piglets. Expression of the sFat-1 gene in 12 of 13 piglets was detected with RT-PCR. The data demonstrates that an efficient system for sFat-1 transgenic cloned pigs was developed, which led to the successful production of piglets expressing the sFat-1 gene. | PAN DengKe1, ZHANG Li1, ZHOU YanRong2, FENG Chong1, LONG Chuan1, LIU Xiao1, WAN Rong3, ZHANG Jian3, LIN AiXing3, DONG EnQiu4, WANG ShuChen4, XU HouGang4 & CHEN HongXing2 1 Institute of Animal Sciences, Chinese Academy of Agricultural Sciences, Beijing 100193, China 2 Beijing Institute of Biotechnology, Beijing 100071, China 3 China Agricultural University, Beijing 100193, China 4 Yutian Breeding Swine Farms, Yutian 064104, China | 2010 | Science China(Life Sciences)2010，53，4： | 21 |
| 15 | Flow-induced vibrations of long circular cylinders modeled by coupled nonlinear oscillators显示文摘The dynamics of long slender cylinders undergoing vortex-induced vibrations (VIV) is studied in this work. Long slender cylinders such as risers or tension legs are widely used in the field of ocean engineering. When the sea current flows past a cylinder, it will be excited due to vortex shedding. A three-dimensional time domain model is formulated to describe the response of the cylinder, in which the in-line (IL) and cross-flow (CF) deflections are coupled. The wake dynamics, including in-line and cross-flow vibrations, is represented using a pair of non-linear oscillators distributed along the cylinder. The wake oscillators are coupled to the dynamics of the long cylinder with the acceleration coupling term. A non-linear fluid force model is accounted for to reflect the relative motion of cylinder to current. The model is validated against the published data from a tank experiment with the free span riser. The comparisons show that some aspects due to VIV of long flexible cylinders can be reproduced by the proposed model, such as vibrating frequency, dominant mode number, occurrence and transition of the standing or traveling waves. In the case study, the simulations show that the IL curvature is not smaller than CF curvature, which indicates that both IL and CF vibrations are important for the structural fatigue damage. | GE Fei LONG Xu WANG Lei HONG YouShi | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 20 |
| 16 | Near-diffraction-limited linearly polarized narrow-linewidth random fiber laser with record kilowatt output显示文摘In this paper, we propose and experimentally investigate a linearly polarized narrow-linewidth random fiber laser(RFL) operating at 1080 nm and boost the output power to kilowatt level with near-diffraction-limited beam quality using a master oscillation power amplifier. The RFL based on a half-opened cavity, which is composed of a linearly polarized narrow-linewidth fiber Bragg grating and a 500 m piece of polarization-maintained Ge-doped fiber, generates a 0.71 W seed laser with an 88 pm full width at half-maximum(FWHM) linewidth and a 22.5 dB polarization extinction ratio(PER) for power scaling. A two-stage fiber amplifier enhances the seed laser to the maximal 1.01 k W with a PER value of 17 dB and a beam quality of M_x^2=1.15 and M_y^2=1.13. No stimulated Brillouin scattering effect is observed at the ultimate power level, and the FWHM linewidth of the amplified random laser broadens linearly as a function of the output power with a coefficient of about 0.1237 pm∕W.To the best of our knowledge, this is the first demonstration of a linearly polarized narrow-linewidth RFL with even kilowatt-level near-diffraction-limited output, and further performance scaling is ongoing. | JIANGMING XU LONG HUANG MAN JIANG JUN YE PENGFEI MA JINYONG LENG JIAN WU HANWEI ZHANG PU ZHOU | 2017 | Photonics Research2017，5，4： | 20 |
| 17 | Clinical trial with traditional Chinese medicine intervention ''tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'' for chronic hepatitis B-associated liver failure显示文摘AIM:To study the clinical efficacy of traditional Chinese medicine(TCM)intervention'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')for treating liver failure due to chronic hepatitis B.METHODS:We designed the study as a randomized controlled clinical trial.Registration number of Chinese Clinical Trial Registry is Chi CTR-TRC-12002961.A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study.Participants were randomly assigned to the following three groups:(1)a modern medicine control group(MMC group,36patients);(2)a'tonifying qi and detoxification'('TQD')group(72 patients);and(3)a'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')group(36patients).Patients in the MMC group received general internal medicine treatment;patients in the'TQD'group were given a TCM formula'tonifying qi and detoxification'and general internal medicine treatment;patients in the'TTK'group were given a TCM formula of'TTK'and general internal medicine treatment.All participants were treated for 8 wk and then followed at 48 wk following their final treatment.The primaryefficacy end point was the patient fatality rate in each group.Measurements of various virological and biochemical indicators served as secondary endpoints.The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups.RESULTS:At the 48-wk post-treatment time point,the patient fatality rates in the MMC,'TQD',and'TTK'groups were 51.61%,35.38%,and 16.67%,respectively,and the differences between groups were statistically significant(P<0.05).However,there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups(P>0.05).Patients in the'TTK'group had significantly higher levels of serum total bilirubin compared to MMC subjects(339.40μmol/L±270.09μmol/L vs 176.13μmol/L±185.70μmol/L,P=0.014).Serum albumin levels were significantly increased in both the'TQD'group and'TTK'group as compared with the MMC group(31.30 g/L±4.77g/L,30.72 g/L±2.89 g/L vs 28.57 g/L±4.56 g/L,P<0.05).There were no significant differences in levels of alanine transaminase among the three groups(P>0.05).Safety data showed that there was one case of stomachache in the'TQD'group and one case of gastrointestinal side effect in the'TTK'group.CONCLUSION:Treatment with'TTK'improved the survival rates of patients with liver failure due to chronic hepatitis B.Additionally,liver tissue was regenerated and liver function was restored. | Han-Min Li Zhi-Hua Ye Jun Zhang Xiang Gao Yan-Ming Chen Xin Yao Jian-Xun Gu Lei Zhan Yang Ji Jian-Liang Xu Ying-He Zeng Fan Yang Lin Xiao Guo-Guang Sheng Wei Xin Qi Long Qing-Jing Zhu Zhao-Hong Shi Lian-Guo Ruan Jia-Yao Yang Chang-Chun Li Hong-Bin Wu Sheng-Duo Chen Xin-La Luo | 2014 | World Journal of Gastroenterology2014，20，48： | 20 |
| 18 | mm Wave communications for 5G: implementation challenges and advances显示文摘The requirement of the fifth generation(5 G) wireless communication for high throughput motivates the wireless industry to use the mm Wave(millimeter wave) communications for its wide bandwidth advantage. To compensate the heavy path loss and increase the communications capacity, phased array beamforming and massive multiple-input multiple-output(MIMO) techniques are employed at both the user equipment(UE) and base stations(BS). Considering the commercial requirements, 5 G mm Wave large array systems should be implemented in an energy-and cost-efficient way with a small form factor. To address above issues and realize a reliable communications link, taking into account the particular characteristics of5 G mm Wave systems, this paper firstly examines the design challenges and trade-offs in system implementations, then some of the design strategies are summarized. At last, recent advance in RF front-end circuits and receiver sub-systems is then highlighted. | Lianming LI Dongming WANG Xiaokang NIU Yuan CHAI Linhui CHEN Long HE Xu WU Fuchun ZHENG Tiejun CUI Xiaohu YOU | 2018 | Science China(Information Sciences)2018，61，2： | 19 |

| 20 | Increased brachial-ankle pulse wave velocity is associated with impaired endothelial function in patients with coronary artery disease显示文摘Background Pulse wave velocity and flow-mediated vasodilation (FMD) are widely used as noninvasive modalities for evaluating atherosclerosis. However, it is not known whether pulse wave velocity is related to FMD in patients with coronary artery disease (CAD). Therefore, the present study was designed to investigate the alteration in brachial-ankle pulse wave velocity (baPWV) and endothelial function in CAD patients. Methods Thirty-three patients with CAD and thirty control subjects were recruited for this study. baPWV was measured non-invasively using a VP 1000 automated PWV/ABI analyzer (PWV/ABI, Colin Co. Ltd., Komaki, Japan). Endothelial function as reflected by FMD in the brachial artery was assessed with a high-resolution ultrasound device. Results baPWV was increased in CAD patients compared with control subjects [(1756.1±253.1) cm/s vs (1495.3±202.3) cm/s, P<0.01]. FMD was significantly reduced in CAD patients compared with control subjects [(5.2±2.1) % vs (11.1±4.4) %, P<0.01]. baPWV correlated with FMD (r =-0.68, P<0.001). The endothelium-independent vasodilation induced by sublingual nitroglycerin in the brachial artery was similar in the CAD group compared with the control group. Conclusions CAD is associated with increased baPWV and endothelial dysfunction. Increased baPWV parallels diminished endothelial function. Our data therefore suggest that baPWV can be used as a noninvasive surrogate index in clinical evaluation of endothelial function. | LIU Dong-hong WANG Yan LIAO Xin-xue XU Ming-guo WANG Jie-mei YANG Zhen CHEN Long LU Ming-de LU Kun TAO Jun | 2006 | Chinese Medical Journal2006，，22： | 17 |
