| 1 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014，27，5： | 17 |
| 2 | Synergistic effect of oxymatrine and angiogenesis inhibitor NM-3 on modulating apoptosis in human gastric cancer cells显示文摘AIM: To investigate the synergistic effect of oxymatrine(OM) and angiogenesis inhibitor NM-3 on modulatingapoptosis in human gastric cancer cell lines SGC-7901,MKN-45, MKN-74. METHODS: Human gastric cancer lines SGC-7901,MKN-45, MKN-74 were treated with OM in the absenceand presence of NM-3. The inhibitory rates weredetected by MTT assay. Synergistic effect of OM andNM-3 on the growth of survivin, bcl-2, bax and p53 inSGC-7901 cells were examined by semiquantitative RT-PCR and Western blotting, and their growth inhibitoryeffects were also observed on SGC-7901 tumor xenograftin nude mice.RESULTS: OM combined with NM-3 exhibited asynergistic inhibitory effect on the growth of SGC-7901,MKN-45 and MKN-74 cells in a time-dependent manner.Twenty-four hours after treatment with OM, NM-3 aloneand their combination, mRNA expression of survivin andbcl-2 in SGC-7901 cells decreased, p53 mRNA expressionincreased. OM (4 g/L) combined with NM-3 significantlyincreased the expression of p53 mRNA and decreasedthe expression of survivin and bcl-2 compared witheither agent alone (193% ± 34% vs 129% ± 12%;44% ± 18% vs 92% ± 18%; 36 ± 17% vs 93% ± 23%,P < 0.05). Western blotting showed that the synergisticeffect of OM and NM-3 on protein translation of survivin,bcl-2 and p 53 was in accordance with their mRNAs.Furthermore, OM/NM-3 combination obviously exhibitedantitumor growth effect in xenografted human gastriccancer cells SGC-7901 compared with either agent alone.CONCLUSION: OM combined with NM-3 has synergisticinhibitory effects on human gastric cancer cells in vitro and can suppress the growth of xenografted human gastric cancer cells SGC-7901 in vivo. | Ming-Quan Song Jin-Shui Zhu Jin-Lian Chen Long Wang Wei Da Li Zhu Wei-Ping Zhang | 2007 | World Journal of Gastroenterology2007，13，12： | 13 |
| 3 | Development and Evaluation of a Distance Learning System Based on CSCW显示文摘This paper described a distance learning system, which allows Internet users to conduct a lesson in real time from any kinds attached computers. Participants can jointly view and edit relevant multimedia information distributed through Internet. Teachers and students can also simultaneously communicate by voice and text to discuss the problems. Teacher can broadcast streaming PowerPoint presentation in real time to network users. In addition to sliders, presenters can broadcast video and audio simultaneously to deliver a live multimedia show online, and store their presentations for on demand playback. Teachers distributed in different places can also use cooperative editing tool to edit and encode existing digital content. We discussed some important design principles of the system. Then, the system configuration and the results of evaluation are also presented. The system has proved to be applicable to the distance learning based on CSCW (Computer Support Cooperative Work) in Internet. | Yin Hao,Zhu Guang\|xi,Li Xiao\|long,Zhu Yao\|ting,He Da\|an Electronic Engineering Department,Huazhong University of Science and Technology , Wuhan 430074,China | 2001 | Wuhan University Journal of Natural Sciences2001，6，Z1： | 2 |
| 4 | Design,synthesis and primary activity of thiomorpholine derivatives as DPP-Ⅳinhibitors显示文摘Thirteen thiomorpholine-bearing compounds were designed and synthesized as dipeptidyl peptidase IV(DPP-IV) inhibitors, with natural and non-natural L-amino acids as the starting materials.Their structures were characterized by ~1H NMR,^(13)C NMR and HR-MS.The target compounds were screened for the DPP-IV inhibition,and the preliminary SAR result was obtained.Particularly, compounds 4c,4d and 4f with good DPP-IV inhibition in vitro were further evaluated through a mouse oral glucose tolerance test (OGTT).The preliminary result showed the potential value for further studies on those thiomorpholine-bearing compounds as DPP-IV inhibitors. | Bei Han Jing Long Liu Yi Huan Peng Li Qi Wu Zi Yun Lin Zhu Fang Shen Da Li Yin Hai Hong Huang | 2012 | Chinese Chemical Letters2012，23，3： | 1 |

| 7 | Evaluation of A Single-reaction Method for Whole Genome Sequencing of Influenza A Virus using Next Generation Sequencing显示文摘Objective To evaluate a single-reaction genome amplification method, the multisegment reverse transcription-PCR(M-RTPCR), for its sensitivity to full genome sequencing of influenza A virus, and the ability to differentiate mix-subtype virus, using the next generation sequencing(NGS) platform. Methods Virus genome copy was quantified and serially diluted to different titers, followed by amplification with the M-RTPCR method and sequencing on the NGS platform. Furthermore, we manually mixed two subtype viruses to different titer rate and amplified the mixed virus with the M-RTPCR protocol, followed by whole genome sequencing on the NGS platform. We also used clinical samples to test the method performance. Results The M-RTPCR method obtained complete genome of testing virus at 125 copies/reaction and determined the virus subtype at titer of 25 copies/reaction. Moreover, the two subtypes in the mixed virus could be discriminated, even though these two virus copies differed by 200-fold using this amplification protocol. The sensitivity of this protocol we detected using virus RNA was also confirmed with clinical samples containing low-titer virus. Conclusion The M-RTPCR is a robust and sensitive amplification method for whole genome sequencing of influenza A virus using NGS platform. | Zou Xiao Hui Chen Wen Bing Zhao Xiang Zhu Wen Fei Yang Lei Wang Da Yan Shu Yue Long | 2016 | Biomedical and Environmental Sciences2016，29，1： | 0 |
