1The Association of Overweight and Obesity with Blood Pressure among Chinese Children and Adolescents显示文摘Objective To examine the association between obesity and high blood pressure (BP) in Chinese children and adolescents. Methods Body mass index (BMI) and blood pressure measurements of 197 191 children aged 7-17 years were obtained from a Chinese national survey in 2010. Obesity and high BP were defined according to the reference values for Chinese children. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of different BMI categories for high BP, as well as the population attributable risk percent (PAR%), were also calculated. Results The prevalence of high BP was 16.1% for boys and 12.9% for girls in 2010. Overweight and obese children had a significantly higher prevalence of high BP than non-overweight children in both boys and girls in each age group. ORs (95% CI) for high BP were 4.1 (3.9, 4.4) in obese boys and 4.0 (3.7, 4.3) in obese girls. The overall PAR% for high BP due to overweight and obesity was 14.4%. Conclusion Overweight and obese children have a significantly higher risk of high BP than non-overweight children. Eliminating overweight and obesity could reduce 14.4% of high BP cases.DONG Bin MA Jun WANG Hai Jun WANG Zhi Qiang 2013Biomedical and Environmental Sciences2013,26,6:42

3Effectiveness 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 2014Biomedical and Environmental Sciences2014,27,5:17

6SbHKT1;4, a member of the high‐affinity potassium transporter gene family from Sorghum bicolor, functions to maintain optimal Na^+/K^+ balance under Na^+ stress显示文摘In halophytic plants, the high‐affinity potassium transporter HKT gene family can selectively uptake Kt in the presence of toxic concentrations of Nat. This has so far not been well examined in glycophytic crops. Here, we report the characterization of SbHKT1;4, a member of the HKT gene family from Sorghum bicolor. Upon Nat stress, SbHKT1;4 expression was more strongly upregulated in salt‐tolerant sorghum accession, correlating with a better balanced Nat/ Kt ratio and enhanced plant growth. Heterogeneous expression analyses in mutants of Saccharomyces cerevisiae and Arabidopsis thaliana indicated that overexpressing SbHKT1;4 resulted in hypersensitivity to Nat stress, and such hypersensitivity could be alleviated with the supply of elevated levels of Kt, implicating that SbHKT1;4 may mediate Kt uptake in the presence of excessive Nat. Further electrophysiological evidence demonstrated that SbHKT1;4 could transport Nat and Kt when expressed in Xenopus laevis oocytes. The relevance of the finding that SbHKT1;4 functions to maintain optimal Nat/Kt balance under Nat stress to the breeding of salt‐tolerant glycophytic crops is discussed.Tian‐Tian Wang Zhi‐Jie Ren Zhi‐Quan Liu Xue Feng Rui‐Qi Guo Bao‐Guo Li Le‐Gong Li Hai‐Chun Jing 2014Journal of Integrative Plant Biology2014,56,3:11

11Relationship between Maternal PBMC HBV cccDNA and HBV Serological Markers and its Effect on HBV Intrauterine Transmission显示文摘Objective To investigate the relationship between maternal peripheral blood mononuclear cells (PBMC) hepatitis B virus(HBV) covalenty closed circular deoxyribonucleic acid(cccDNA) and other HBV serological markers and its effects on HBV intrauterine transmission. Methods We enrolled 290 newborns and their hepatitis B surface antigen(HBsAg) positive mothers. HBV cccDNA in PBMC and HBV DNA in serum were detected by a real‐time PCR‐TaqM an probe while HBV serological markers were detected with an electrochemiluminescence immunoassay. Results There was a positive correlation between the levels of PBMC HBV cccD NA and serum HBV DNA and HBeA g(r = 0.436 and 0.403, P < 0.001). The detection rate of pattern A [‘HBsA g(+), HBeA g(+), and anti‐HBc(+)’] was significantly higher in the PBMC HBV cccD NA positive group than in the control group(χ^2 = 48.48, P < 0.001). There was a significant association between HBV intrauterine transmission and PBMC HBV cccD NA(χ^2 = 9.28, P = 0.002). In the presence of serum HBV DNA, HBeA g, and PBMC HBV cccD NA, the risk of HBV intrauterine transmission was three times higher(OR = 3.69, 95% CI: 1.30‐10.42) than that observed in their absence. The risk of HBV intrauterine transmission was the greatest(OR = 5.89, 95% CI: 2.35‐14.72) when both PBMC HBV cccD NA and pattern A were present. A Bayesian network model showed that maternal PBMC HBV cccD NA was directly related to HBV intrauterine transmission. Conclusion PBMC HBV cccDNA may be a direct risk factor for HBV intrauterine transmission. Our study suggests that serological markers could be combined with PBMC‐related markers in prenatal testing.WANG Dan Dan YI Lin Zhu WU Li Na YANG Zhi Qing HAO Hai Yun SHI Xiao Hong WANG Bo FENG Shu Ying FENG Yong Liang WANG Su Ping 2019Biomedical and Environmental Sciences2019,32,5:8

13Increased Chondrocyte Apoptosis in Kashin-Beck Disease and Rats Induced by T-2 Toxin and Selenium Deficiency显示文摘Objective To investigate chondrocyte apoptosis and the expression of biochemical markers associated with apoptosis in Kashin-Beck disease(KBD) and in an established T-2 toxin-and selenium(Se) deficiency-induced rat model. Methods Cartilages were collected from the hand phalanges of five patients with KBD and five healthy children. Sprague-Dawley rats were administered a selenium-deficient diet for 4 weeks prior to T-2 toxin exposure. The apoptotic chondrocytes were observed by terminal deoxynucleotidyl transferase d UTP nick end labeling staining. Caspase-3, p53, Bcl-2, and Bax proteins in the cartilages were visualized by immunohistochemistry, their protein levels were determined by Western blotting, and m RNA levels were determined by real-time reverse transcription polymerase chain reaction. Results Increased chondrocyte apoptosis was observed in the cartilages of children with KBD. Increased apoptotic and caspase-3-stained cells were observed in the cartilages of rats fed with normal and Se-deficient diets plus T-2 toxin exposure compared to those in rats fed with normal and Se-deficient diets. Caspase-3, p53, and Bax proteins and m RNA levels were higher, whereas Bcl-2 levels were lower in rats fed with normal or Se-deficiency diets supplemented with T-2 toxin than the corresponding levels in rats fed with normal diet. Conclusion T-2 toxin under a selenium-deficient nutritional status induces chondrocyte death, which emphasizes the role of chondrocyte apoptosis in cartilage damage and progression of KBD.YANG Hao Jie ZHANG Ying WANG Zhi Lun XUE Sen Hai LI Si Yuan ZHOU Xiao Rong ZHANG Meng FANG Qian WANG Wen Jun CHEN Chen DENG Xiang Hua CHEN Jing Hong 2017Biomedical and Environmental Sciences2017,30,5:7
14Subchronic Oral Toxicity Evaluation of Lanthanum: A 90-day, Repeated Dose Study in Rats显示文摘Objective The present study was undertaken to evaluate the subchronic toxicity of lanthanum and to determine the no observed adverse effect level(NOAEL),which is a critical factor in the establishment of an acceptable dietary intake(ADI).Methods In accordance with the Organization for Economic Co-operation and Development(OECD) testing guidelines,lanthanum nitrate was administered once daily by gavage to Sprague-Dawley(SD) rats at dose levels of 0,1.5,6.0,24.0,and 144.0 mg/kg body weight(BW) per day for 90 days,followed by a recovery period of 4 weeks in the 144.0 mg/kg BW per day and normal control groups.Outcome parameters were mortality,clinical symptoms,body and organ weights,serum chemistry,and food consumption,as well as ophthalmic,urinary,hematologic,and histopathologic indicators.The benchmark dose(BMD) approach was applied to estimate a point of departure for the hazard risk assessment of lanthanum.Results Significant decreases were found in the 144.0 mg/kg BW group in the growth index,including body weight,organ weights,and food consumption.This study suggests that the NOAEL of lanthanum nitrate is 24.0 mg/kg BW per day.Importantly,the 95% lower confidence value of the benchmark dose(BMDL) was estimated as 9.4 mg/kg BW per day in females and 19.3 mg/kg BW per day in males.Conclusion The present subchronic oral exposure toxicity study may provide scientific data for the risk assessment of lanthanum and other rare earth elements(REEs).FANG Hai Qin YU Zhou ZHI Yuan FANG Jin LI Chen Xi WANG Yi Mei PENG Shuang Qing JIA Xu Dong 2018Biomedical and Environmental Sciences2018,31,5:7
15Epidemiological Characteristics and Risk Factors of the Pertussis in Infants < 12 Months of Age in Tianjin, China显示文摘The epidemiologic characteristics of 631 infant pertussis cases<12 months,which accounted for57.42%of the total cases,were analyzed by descriptive epidemiology in Tianjin,between 2010and 2015.The incidence of infants was104.66/100,000,which was 118 times higher than in other age groups(P<0.001).The primary type of pertussis simultaneously presented in households was adult-to-infant(70.51%).The parents were identified as the source of infection in 80.18%of cases for infants.The positive rate of placental antibody transfer was 31.06%and 3.13%for3-month-old infants.Infants presented the highest age-specific pertussis incidence.The most important reason was parents were the important sources of infection,and secondly the lower level of antibodies in neonates and the rapid waning of maternal antibody titer.HUANG Hai Tao GAO Zhi Gang LIU Yong WANG Li Juan LIU Yan Ping ZHANG Ying 2017Biomedical and Environmental Sciences2017,30,7:7

17Compression-related EMIC waves drive relativistic electron precipitation显示文摘With coordinated observations of the NOAA 15 satellite and OUL magnetometer station in Finland, we report that the electromagnetic ion cyclotron(EMIC) waves which were stimulated by the compression of the magnetosphere drive relativistic electron precipitation in geoquiescence on 1 Jan 2007. After an enhancement of solar wind dynamic pressure(SWDP), a dayside Pc1 pulsation was observed by the OUL station. Such a Pc1 pulsation is caused by an EMIC wave which propagates from the generation source to lower altitudes. Simultaneously, the NOAA 15 satellite registered an enhancement of precipitating electron count rates with energies >3 Me V within the anisotropic zone of protons. This phenomenon is coincident with the quasi-linear theoretical calculation presented in this paper. Our observations suggest that after a positive impulse of solar wind, the compression-related EMIC waves can drive relativistic electrons precipitation and play a pivotal role in the dynamic of radiation belts.WANG De Dong YUAN Zhi Gang DENG Xiao Hua ZHOU Meng HUANG Shi Yong LI Ming LI Hui Min LI Hai Meng RAITA Tero PANG Ye 2014Science China(Technological Sciences)2014,57,12:6
18Quantitative Analysis of the Feedback Induced by the Freshwater Flux in the Tropical Pacific Using CMIP5显示文摘Freshwater flux(FWF) directly affects sea surface salinity(SSS) and hence modulates sea surface temperature(SST) in the tropical Pacific. This paper quantifies a positive correlation between FWF and SST using observations and simulations of the fifth phase of the Coupled Model Intercomparison Project(CMIP5) to analyze the interannual variability in the tropical Pacific. Comparisons among the displacements of FWF,SSS and SST interannual variabilities illustrate that a large FWF variability is located in the west-central equatorial Pacific,covarying with a large SSS variability,whereas a large SST variability is located in the eastern equatorial Pacific. Most CMIP5 models can reproduce the fact that FWF leads to positive feedback to SST through an SSS anomaly as observed. However,the difference in each model's performance results from different simulation capabilities of the CMIP5 models in the magnitudes and positions of the interannual variabilities,including the mixed layer depth and the buoyancy flux in the equatorial Pacific. SSS anomalies simulated from the CMIP5 multi-model are sensitive to FWF interannual anomalies,which can lead to differences in feedback to interannual SST variabilities. The relationships among the FWF,SSS and SST interannual variabilities can be derived using linear quantitative measures from observations and the CMIP5 multi-model simulations. A 1 mm d-1FWF anomaly corresponds to an SSS anomaly of nearly0.12 psu in the western tropical Pacific and a 0.11?C SST anomaly in the eastern tropical Pacific.ZHI Hai ZHANG Rong-Hua LIN Pengfei WANG Lanning 2015Advances in Atmospheric Sciences2015,32,10:6

20Comparison of Histological, Microbiological, and Molecular Methods in Diagnosis of Patients with TBLN Having Different Anti-TB Treatment Background显示文摘Objective The influence of anti-tuberculosis(TB) treatment history on tuberculous lymphadenitis(TBLN) diagnosis is unclear. Therefore, this study aims to evaluate the diagnostic methods, including histology, microbiology, and molecular tests, used for TBLN. Methods In this study, suspected patients with TBLN and having different anti-TB treatment background were enrolled. All the samples were tested simultaneously by histology, Ziehl-Neelsen(ZN) staining, mycobacterial culture(culture), Xpert MTB/RIF(xpert), real-time PCR, and high-resolution melting curve PCR(HRM). Thereafter, the performance of these methods on samples with different anti-TB treatment background was assessed. Results In our study, 89 patients were prospectively included 82 patients with TBLN and 7 with other diseases. The overall sensitivities of Xpert, real-time PCR, histology, ZN staining, and culture were 86.6%, 69.5%, 58.5%, 43.9%, and 22.0%, respectively. The anti-TB treatment history revealed dramatic influences on the sensitivity of culture(P < 0.0001). In fact, the treatment that lasted over 3 months also influenced the sensitivity of Xpert(P < 0.05). However, the treatment history did not affect the performance of remaining tests(P > 0.05). For rifampicin drug susceptibility test(DST), the anti-TB treatment showed only significant influence on the success rate of culture DST(P = 0.001), but not on those of Xpert and HRM tests(P > 0.05). Conclusion Other tests as well as culture should be considered for patients with TBLN having retreatment history or over 1-month treatment to avoid false negative results.CHE Nan Ying HUANG Shao Jun MA Yan HAN Yi LIU Zi Chen ZHANG Chen MU Jing ZHAO Dan QU Yang ZHANG Hai Qing LIU Zhi Dong XU Shao Fa 2017Biomedical and Environmental Sciences2017,30,6:6
