| 3 | Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China. | HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li | 2014 | Biomedical and Environmental Sciences2014，27，5： | 3 |
| 4 | Theory and verification of operator design methodology显示文摘Non-recurring-engineering(NRE)and time-to-market play an increasingly important role in the field of IC design.Meanwhile,with the continuous development of IC manufacturing technology,it is necessary to propose a novel design methodology to shorten design cycle and enhance design efficiency.In this paper,operator design methodology(ODM)is presented and an H.264 encoder is implemented as a verification.According to the flow of ODM,the register transfer level(RTL)design of H.264 encoder has been accomplished with 15 man-months,which is lower than the average 19 man-months in the field of traditional application specific integrated circuit(ASIC)design.Moreover,with the advantage of operator design library,the design has a comparable performance with other ASIC implementations.The obtained design can support a real-time video encoding of 720p at 60 frames per second or 1080p at 30 frames per second,working at 167 MHz with SMIC 0.13 μm CMOS technology.These results provide good evidence for the practicability and efficiency of ODM. | HU Ziyi ZHAO Yong WANG XinAn HUANG Ru WANG Teng ZHANG Xing | 2012 | Science China(Information Sciences)2012，55，2： | 3 |

| 6 | Prognostic Values of Serum Chloride and Sodium Levels in Patients with Three-vessel Disease显示文摘Objective Identification of new risk factors is needed to improve prediction of adverse outcomes in patients with three-vessel disease(TVD). The present study aimed to evaluate the prognostic values of serum chloride and sodium levels in patients with TVD. Methods We used data from a prospective cohort of consecutive patients with angiographically confirmed TVD. The primary endpoint was all-cause death. Cox proportional hazard regression was used to analyze the relationship of serum chloride and sodium levels with long-term outcomes of TVD patients. Results A total of 8,318 participants with available serum chloride and sodium data were included in this analysis. At baseline, patients in the low tertiles group of serum chloride level(≤ 102.0 mmol/L) or serum sodium level(≤ 139.0 mmol/L) had more severe disease conditions. During a median follow-up of 7.5-year, both low serum chloride level and low serum sodium level were found to be associated with an increased risk for mortality in univariate analysis. However, when both parameters were incorporated into a multivariate model, only low serum sodium level remained to be an independent predictor of all-cause death(hazard ratio: 1.16, 95% confidence interval: 1.01-1.34, P = 0.041). Modest but significant improvement of discrimination was observed after incorporating serum sodium level into the Synergy between percutaneous coronary intervention(PCI) with Taxus and Cardiac Surgery score. Conclusion Serum sodium level is more strongly associated with long-term outcomes of TVD patients compared with serum chloride level. Low serum sodium level is an independent risk factor for mortality, but only provides modest prognostic information beyond an established risk model. | ZHANG Ce WANG Dong HOU Bing Jie JIANG Lin XU Lian Jun TIAN Jian ZHAO Yan Yan ZHAO Xue Yan FENG Xin Xing ZHANG Yin SUN Kai XU Bo ZHAO Wei HUI Ru Tai GAO Run Lin LOU Hui Ling YUAN Jin Qing SONG Lei | 2019 | Biomedical and Environmental Sciences2019，32，4： | 1 |
| 7 | Specific detection and effective inhibition of a single bacterial species in situ using peptide mineralized Au cluster probes显示文摘Increasingly serious microbial infections call for the development of new simpler methods for the precise diagnosis and specific inhibition of such pathogens. In this work, a peptide mineralized Au cluster probe was applied as a new simplified strategy to both recognize and inhibit a single bacteria species of Staphylococcus aureus(S. aureus) simultaneously. The probes are composed of peptides and Au clusters. Moreover, the peptides specifically target S. aureus cells and the Au clusters provide fluorescent imaging and have an antibacterial effect. These new probes enable the simultaneous specific detection and effective destruction S. aureus cells in situ. | Xiangchun Zhang Li Liu Ru Liu Jing Wang Xuhu Hu Qing Yuan Juanjuan Guo Gengmei Xing Yuliang Zhao Xueyun Gao | 2018 | Science China Chemistry2018，61，5： | 0 |
| 8 | Impact of antagonist peptides and chelators on the diagnostic performance of PET/CT using gallium-68 labeled somatostatin receptor antagonists显示文摘Objective:Different SSTR2 antagonists have been developed.This study aims to evaluate the impact of different peptides and chelators on the diagnostic performance of SSTR2 antagonists in well-differentiated NETs.Methods:In this prospective study,participants were equally randomized into two arms:Arm A,participants would undergo a whole-body 68Ga-NODAGA-LM3 PET/CT scan on the 1st day and 68Ga-DOTA-LM3 PET/CT scan on the 2nd day;Arm B,participants would undergo a whole-body 68Ga-NODAGA-LM3 PET/CT scan on the 1st day and 68Ga-NODAGA-JR11 PET/CT scan on the 2nd day.Biodistribution in normal organs,lesion detection ability,and tumor uptakes were compared within each Arm.Results:A total of 40 participants(age,49.5±13.4,21 men),20 in each arm,were recruited in the study.In Arm A,68Ga-DOTA-LM3 showed lower background.However,the lesion detection ability(overall lesion detected,445 versus 548,P=0.005)and the lesion uptake(overall lesions SUVmax,19.8±17.2 versus 35.3±28.8,P<0.001)was significantly lower than those of 68Ga-NODAGA-LM3.In Arm B,both 68Ga-NODAGA-LM3 and 68Ga-NODAGA-JR11 showed similar biodistribution and lesion uptake(SUVmax,28.5±23.8 versus 25.0±20.0,P<0.001)despite minor differences.The lesion detection ability was the same between these two tracers(overall lesion detected,503 versus 503).Conclusions:The diagnostic performance of SSTR2 antagonists was sensitive to chelators.Both 68Ga-NODAGA-LM3 and 68Ga-NODAGA-JR11 outperformed 68Ga-DOTA-LM3 with higher lesion uptake and detection ability,of which 68Ga-NODAGA-LM3 had marginally but significantly higher lesion uptake. | Haiqun Xing Wenjia Zhu Yuejuan Cheng Qiao Yang Ru Jia Hong Zhao Chunmei Bai Li Huo Wenming Wu | 2022 | Journal of Pancreatology2022，5，3： | 0 |
