| 4 | 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 |
| 5 | Degradation Mechanism of Cationic Red X-GRL by Ozonation显示文摘The degradation mechanism of Cationic Red X-GRL was investigated when the intermediates, the nitrate ion and the pH were analyzed in the ozonation. The degradation of the Cationic Red X-GRL includes the de-auxochrome stage, the decolour stage, and the decomposition of fragment stage. During the degradation process, among the six nitrogen atoms of Cationic Red X-GRL, one is transferred into a nitrate ion, one becomes the form of an amine compound, and the rest four are transformed into two molecules of nitrogen. In the course of the ozonation of Cationic Red X-GRL, the direct attack of ozone is the main decolour effect. | Wei Rong ZHAO*, Xin Hua XU, Hui Xiang SHI, Da Hui WANG Department of Environmental Engineering, Zhejiang University, Hangzhou 310027 | 2003 | Chinese Chemical Letters2003,14,12: | 14 |

| 7 | 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 |

| 10 | Key nodes of a micro RNA network associated with the integrated mesenchymal subtype of high-grade serous ovarian cancer显示文摘Metastasis is the main cause of cancer mortality. One of the initiating events of cancer metastasis of epithelial tumors is epithelial-to-mesenchymal transition(EMT), during which cells dedifferentiate from a relatively rigid cell structure/morphology to a flexible and changeable structure/morphology often associated with mesenchymal cells. The presence of EMT in human epithelial tumors is reflected by the increased expression of genes and levels of proteins that are preferentially present in mesenchymal cells. The combined presence of these genes forms the basis of mesenchymal gene signatures, which are the foundation for classifying a mesenchymal subtype of tumors. Indeed, tumor classification schemes that use clustering analysis of large genomic characterizations, like The Cancer Genome Atlas(TCGA), have defined mesenchymal subtype in a number of cancer types, such as high-grade serous ovarian cancer and glioblastoma. However, recent analyses have shown that gene expression-based classifications of mesenchymal subtypes often do not associate with poor survival. This 'paradox' can be ameliorated using integrated analysis that combines multiple data types. We recently found that integrating m RNA and micro RNA(mi RNA) data revealed an integrated mesenchymal subtype that is consistently associated with poor survival in multiple cohorts of patients with serous ovarian cancer. This network consists of 8 major mi RNAs and 214 m RNAs. Among the 8 mi RNAs, 4 are known to be regulators of EMT. This review provides a summary of these 8 mi RNAs, which were associated with the integrated mesenchymal subtype of serous ovarian cancer. | Yan Sun Fei Guo Marina Bagnoli Feng-Xia Xue Bao-Cun Sun Ilya Shmulevich Delia Mezzanzanica Ke-Xin Chen Anil K.

| 13 | Mycoplasma pneumoniae Macrolide Resistance and MLVA Typing in Children in Beijing,China,in 2016:Is It Relevant?显示文摘Objective The aim of this study is to investigate the macrolide resistance rate and molecular type with multiple-locus variable-number tandem-repeat analysis(MLVA)of Mycoplasma pneumoniae of Beijing in 2016 in pediatric patients.Methods Real-time quantitative polymerase chain reaction(PCR)was used to identify M.pneumoniae,and MLVA was performed.The domain V of the 23 S rRNA was sequenced to detect macrolide-resistant point mutations.We also investigated the activities of antibiotics against M.pneumoniae isolates in vitro.Results The PCR detection rate of M.pneumoniae in children in Beijing was 40%,and the macrolide resistance rate was 66%.The A2063 G mutation in the 23 S rRNA V region is the dominant mutation(137/146,93.84%),whereas the A2064 G mutation is rare(9/146,6.16%).Seventy-three samples were typed successfully by MLVA typing,including 86.3%(63/73)were MLVA type 4-5-7-2,and 13.7%(10/73)were MLVA type 3-5-6-2.No other types were found.No strains were resistant to levofloxacin or tetracycline.Conclusion In 2016,a specific decrease in the macrolide resistance rate occurred in Beijing.The detection rate and macrolide resistance rate of outpatients are lower than those of inpatients.The A2063 G mutants M.pneumoniae have high levels of resistance to erythromycin and azithromycin.The primary MLVA type is 4-5-7-2,followed by 3-5-6-2.No other MLVA types were detected.No strains resistant to tetracycline or levofloxacin were found in vitro. | DOU Hai Wei TIAN Xiu Jun XIN De Li WEI Ran ZHOU Wei WANG Hong QIN Xuan Guang SHAO Jun Yan XU Bao Ping GE Li Xia SHI Da Wei | 2020 | Biomedical and Environmental Sciences2020,33,12: | 9 |
| 14 | Effect of heparin on apoptosis in human nasopharyngeal carcinoma CNE2 cells显示文摘In order to study the mechanism of the effect of heparin on apoptosis in carcinoma cells, the nasopharyngeal carcinoma cell line CNE2 was used to identify the effect of heparin on apoptosis associated with the expression of c-myc, bax, bcl-2 proteins by use of Hoechst 33258 staining, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL), agarose gel electrophoresis, and flow cytometry, as well as Western blot analysis. The results showed that heparin induced apoptosis of CNE2 cells including the morphologic changes such as reduction in the volume, and the nuclear chromatin condensation, as well as the “ladder pattern” revealed by agarose gel electrophoresis of DNA in a concentration-dependent manner.The number of TUNEL-positive cells was dramatically increased to 33.6±1.2% from 2.8±0.3% by treat ment with heparin in different concentrations (10~40 kU/L). The apoptotic index was increased to 32.5% from 3.5% by detecting SubG1 peaks on flow cytometry. Western blot analysis showed that levels of bcl-2,bax and c-myc were significantly overexpressed by treatment with the increase of heparin concentrations.These results suggest that heparin induces apoptosis of CNE2 cells, which may be regulated by differential expression of apoptosis-related genes. | LI HONG LIANG , KAI HE YE , HAI WEI ZHANG , YING RU LUO , XIAN DA REN, AI HUA XIONG, RUI SITU Department of Pharmacology ,Pharmacy College, Department of Pathology Medical College, Jinan University, Guangzhou 510632, China | 2001 | Cell Research2001,11,4: | 9 |

| 16 | Nicotinamide overload may play a role in the development of type 2 diabetes显示文摘AIM: To investigate whether nicotinamide overload plays a role in type 2 diabetes. METHODS: Nicotinamide metabolic patterns of 14diabetic and 14 non-diabetic subjects were compared using HPLC. Cumulative effects of nicotinamide and N1-methylnicotinamide on glucose metabolism, plasma H2O2 levels and tissue nicotinamide adenine dinucleotide (NAD) contents of adult Sprague-Dawley rats were observed. The role of human sweat glands and rat skin in nicotinamide metabolism was investigated using sauna and burn injury, respectively. RESULTS: Diabetic subjects had significantly higher plasma N 1-methylnicotinamide levels 5 h after a 100-mg nicotinamide load than the non-diabetic subjects (0.89 ± 0.13 μmol/L vs 0.6 ± 0.13 μmol/L, P < 0.001). Cumulative doses of nicotinamide (2 g/kg) significantly increased rat plasma N 1-methy lnico-tinamide concentrations associated with severe insulin resistance, which was mimicked by N1-methy-lnicotinamide. Moreover, cumulative exposure to N1-methylnicotinamide (2 g/kg) markedly reduced rat muscle and liver NAD contents and erythrocyte NAD/NADH ratio, and increased plasma H2O2 levels. Decrease in NAD/NADH ratio and increase in H2O2 generation were also observed in human erythrocytes after exposure to N1-methylnicotinamide in vitro. Sweating eliminated excessive nicotinamide (5.3-fold increase in sweat nicotinamide concentration 1 h after a 100-mg nicotinamide load). Skin damage or aldehyde oxidase inhibition with tamoxifen or olanzapine, both being notorious for impairing glucose tolerance, delayed N1-methylnicotinamide clearance. CONCLUSION: These f indings suggest that nicotinamide overload, which induced an increase in plasma N 1-methylnicotinamide, associated with oxidative stress and insulin resistance, plays a role in type 2 diabetes. | Shi-Sheng Zhou Da Li Wu-Ping Sun Ming Guo Yong-Zhi Lun Yi-Ming Zhou Fu-Cheng Xiao Li-Xin Jing Shen-Xia Sun Li-Bin Zhang Ning Luo Fu-Ning Bian Wei Zou Lai-Bin Dong Zhi-Gang Zhao Sheng-Fan Li Xiao-Jie Gong Zeng-Guo Yu Chang-Bin Sun Cong-Long Zheng Dong-Ju Jiang Zheng-Ning Li | 2009 | World Journal of Gastroenterology2009,15,45: | 8 |
| 17 | Laser direct writing and characterizations of flexible piezoresistive sensors with microstructures显示文摘Functional materials with high viscosity and solid materials have received more and more attentions in flexible pressure sensors,which are inadequate in the most used molding method.Herein,laser direct writing(LDW)method is proposed to fabricate flexible piezoresistive sensors with microstructures on PDMS/MWCNTs composites with an 8%MWCNTs mass fraction.By controlling laser energy,microstructures with different geometries can be obtained,which significantly impacts the performances of the sensors.Subsequently,curved microcones with excellent performance are fabricated under parameters of f=40 kHz and v=150 mm·s^(-1).The sensor exhibits continuous multi-linear sensitivity,ultrahigh original sensitivity of 21.80%kPa^(-1),wide detection range of over 20 kPa,response/recovery time of~100 ms and good cycle stability for more than 1000 times.Besides,obvious resistance variation can be observed when tiny pressure(a peanut of 30 Pa)is applied.Finally,the flexible piezoresistive sensor can be applied for LED brightness controlling,pulse detection and voice recognition. | Chenying Zhang Wei Zhou Da Geng Cheng Bai Weida Li Songyue Chen Tao Luo Lifeng Qin Yu Xie | 2021 | Opto-Electronic Advances2021,4,4: | 7 |
| 18 | Microjet flow control in an ultra-compact serpentine inlet显示文摘Microjets are used to control the internal flow to improve the performance of an ultra-compact serpentine inlet. A highly offset serpentine inlet with length-to-diameter ratio of2.5 is designed and static tests are conducted to analyze the internal flow characteristics in terms of pressure recovery, distortion and flow separation. Flow separation is encountered in the second S-turn, and two strong counter-rotating vortices are formed at the aerodynamic interface plane(AIP) face which occupy a quarter of the outlet area and result in severe pressure loss and distortion. A flow control model employing a row of microjets in the second turn is designed based on the internal flow characteristics and simplified CFD simulations. Flow control tests are conducted to verify the control effectiveness and understand the characteristics as a function of inlet throat Mach number, injection mass flow ratio, jet Mach number and momentum coefficient. At all test Mach numbers, microjet flow control(MFC) effectively improves the recovery and reduces the distortion intensity. Between inlet throat Mach number 0.2 and 0.5, the strong flow separation in the second S-turn is suppressed at an optimum jet flow ratio of less than 0.65%, resulting in a maximum improvement of 4% for pressure recovery coefficient and a maximum decrease of75% for circumferential distortion intensity at cruise. However, in order to suppress the flow separation, the injection rate should retain in an effective range. When the injection rate is higher than this range, the flow is degraded and the distortion contour is changed from 90° circumferential distortion pattern to 180° circumferential distortion pattern. Detailed data analysis shows that this optimum flow ratio depends on inlet throat Mach number and the momentum coefficient affects the control effectiveness in a dual stepping manner. | Da Xingya Fan Zhaolin Fan Jianchao Zeng Liquan Rui Wei Zhou Run | 2015 | Chinese Journal of Aeronautics2015,28,5: | 7 |
