4Comparing the Diagnostic Criteria for Gestational Diabetes Mellitus of World Health Organization 2013 with 1999 in Chinese Population显示文摘INTRODUCTION Gestational diabetes mellitus (GDM) was earlier defined as 'hyperglycemia first recognized during pregnancy' and has more recently been described by American Diabetes Association (ADA) (2012) as diabetes diagnosed during pregnancy that is not clearly overt diabetes.[1] The hyperglycemia and adverse pregnancy outcomes study (HAPO) demonstrated that the risk of adverse maternal,fetal,and neonatal outcomes continuously increase as a function of maternal glycemia at 24-28 weeks,even within ranges previously considered normal for pregnancy.[2] After reviewing the results of the HAPO study,many international diabetes study groups,including the International Association of Diabetes and Pregnancy Study Groups and ADA have adopted the 75 g oral glucose tolerance test (OGTT) at 24-28 weeks as a screening and diagnostic test and defined new cut-off values for GDM diagnosis.The Ministry of Health of China published the criteria for GDM,that is the same as the ADA criteria on July 1,2011.World Health Organization (WHO) has recommended the 75 g OGTT with different cut-offvalues as a diagnostic test since 1999,changed its recommendation on 2013.In Hongkong and Yunnan province in China,most hospital adopted the WHO 1999 criteria,nevertheless,there is no evidence of multicenter and large sample to show that the GDM population within the same ethnic group diagnosed by the new WHO criteria matches those diagnosed by the old one and consistency between the two criteria has not been reported.Thus,we conducted this study to analyze the two criteria in Chinese pregnant women.Weiwei Zhu Huixia Yang Yumei Wei Zilian Wang Xuelan Li Hairong Wu Nan Li Meihua Zhang Xinghui Liu Hua Zhang Yunhui Wang Jianmin Niu Yujie Gan Liruo Zhong Yunfeng Wang Anil Kapur 2015Chinese Medical Journal2015,,1:42
5Entecavir vs lamivudine therapy for na?ve patients with spontaneous reactivation of hepatitis B presenting as acute-on-chronic liver failure显示文摘AIM:To investigate the short-term and long-term efficacy of entecavir versus lamivudine in patients with spontaneous reactivation of hepatitis B presenting as acute-on-chronic liver failure(ACLF).METHODS:This was a single center,prospective cohort study.Eligible,consecutive hospitalized patients received either entecavir 0.5 mg/d or lamivudine 100mg/d.All patients were given standard comprehensive internal medicine.The primary endpoint was survival rate at day 60,and secondary endpoints were reduction in hepatitis B virus(HBV)DNA and alanine aminotransferase(ALT)levels,and improvement in Child-Turcotte-Pugh(CTP)and model for end-stage liver disease(MELD)scores at day 60 and survival rate at week 52.RESULTS:One hundred and nineteen eligible subjects were recruited from 176 patients with severe acute exacerbation of chronic hepatitis B:65 were included in the entecavir group and 54 in the lamivudine group(full analysis set).No significant differences were found in patient baseline clinical parameters.At day 60,entecavir did not improve the probability of survival(P=0.066),despite resulting in faster virological suppression(P<0.001),higher rates of virological response(P<0.05)and greater reductions in the CTP and MELD scores(all P<0.05)than lamivudine.Intriguingly,at week 52,the probability of survival was higher in the entecavir group than in the lamivudine group[42/65(64.6%)vs 26/54(48.1%),respectively;P=0.038].The pretreatment MELD score(B,1.357;95%Cl:2.138-7.062;P=0.000)and virological response at day30(B,1.556;95%Cl:1.811-12.411;P=0.002),were found to be good predictors for 52-wk survival.CONCLUSION:Entecavir significantly reduced HBV DNA levels,decreased the CTP and MELD scores,and thereby improved the long-term survival rate in patients with spontaneous reactivation of hepatitis B presenting as ACLF.Yang Zhang Xiao-Yu Hu Sen Zhong Fang Yang Tao-You Zhou Guo Chen Yan-Yan Wang Jian-Xing Luo 2014World Journal of Gastroenterology2014,20,16:42
6Clinicopathological and prognostic analysis of 429 patients with intrahepatic cholangiocarcinoma显示文摘AIM:To understand the clinicopathological characteristics and treatment selections and improve survival and provide valuable information for patients with intrahepatic cholangiocarcinoma(ICC). METHODS:We retrospectively evaluated 5311 liver cancer patients who received resection between October 1999 and December 2003.Of these,429(8.1%)patients were diagnosed with ICC,and their clinicopathological, surgical,and survival characteristics were analyzed. RESULTS:Upper abdominal discomfort or pain(65.0%), no symptoms(12.1%),and hypodynamia(8.2%)were the major causes for medical attention.Laboratory tests showed 198(46.4%)patients were HBsAg positive, 90(21.3%)hadα-fetoprotein>20μg/L,50(11.9%) carcinoembryonic antigen>10μg/L,and 242(57.5%) carbohydrate antigen 19-9(CA19-9)>37 U/mL.Survival data was available for 329(76.7%)patients and their mean survival time was 12.4 mo.The overall survival of the patients with R0,R1 resection and punching exploration were 18.3,6.6 and 5.6 mo,respectively. Additionally,CA19-9>37 U/mL was associated with lymph node metastases,but inversely associated withcirrhosis.Multivariate analysis indicated that radical resection,lymph node metastases,macroscopic tumor thrombi and size,and CA19-9 were associated with prognosis. CONCLUSION:Surgical radical resection is still the most effective means to cure ICC.Certain laboratory tests(such as CA19-9)can effectively predict the survival of the patients with ICC.Wei-Feng Shen Wei Zhong Feng Xu Tong Kan Li Geng Feng Xie Cheng-Jun Sui Jia-Mei Yang 2009World Journal of Gastroenterology2009,15,47:39

9Intelligent and connected vehicles: Current status and future perspectives显示文摘Intelligent connected vehicles(ICVs) are believed to change people's life in the near future by making the transportation safer,cleaner and more comfortable. Although many prototypes of ICVs have been developed to prove the concept of autonomous driving and the feasibility of improving traffic efficiency, there still exists a significant gap before achieving mass production of high-level ICVs. The objective of this study is to present an overview of both the state of the art and future perspectives of key technologies that are needed for future ICVs. It is a challenging task to review all related works and predict their future perspectives, especially for such a complex and interdisciplinary area of research. This article is organized to overview the ICV key technologies by answering three questions: what are the milestones in the history of ICVs; what are the electronic components needed for building an ICV platform; and what are the essential algorithms to enable intelligent driving? To answer the first question, the article has reviewed the history and the development milestones of ICVs. For the second question, the recent technology advances in electrical/electronic architecture, sensors, and actuators are presented. For the third question, the article focuses on the algorithms in decision making, as the perception and control algorithm are covered in the development of sensors and actuators. To achieve correct decision-making, there exist two different approaches: the principle-based approach and data-driven approach. The advantages and limitations of both approaches are explained and analyzed. Currently automotive engineers are concerned more with the vehicle platform technology, whereas the academic researchers prefer to focus on theoretical algorithms. However, only by incorporating elements from both worlds can we accelerate the production of high-level ICVs.YANG DianGe JIANG Kun ZHAO Ding YU ChunLei CAO Zhong XIE ShiChao XIAO ZhongYang JIAO XinYu WANG SiJia ZHANG Kai 2018Science China(Technological Sciences)2018,61,10:31

11Postoperative adjuvant antiviral therapy for hepatitis B/C virus-related hepatocellular carcinoma:A meta-analysis显示文摘AIM:To investigate the impact of postoperative antiviral treatment on tumor recurrence and survival of patients with chronic hepatitis B virus(HBV) or hepatitis C virus(HCV) infection-related primary hepatocellular carcinoma(HCC) after curative therapy.METHODS:We performed a meta-analysis of randomized and non-randomized control trials from electronic search and manual search.The fixed effect model of Mantel-Haenszel method and the random effect model of Der Simonian and Laird method were used for homogeneous and heterogeneous studies,respectively.Seven HCV-related studies,three HBV-related studies and three studies on HBV or HCV-related HCC were identified.RESULTS:A total of 1224 patients were included in this analysis.The estimated odds ratios(OR) for the 1-,2-,3-and 5-year recurrence were 0.54 [15.4% vs 24.1%,95% confidence interval(CI):0.32-0.89,P=0.02],0.42(36.9% vs 58.0%,95% CI:0.19-0.90,P=0.03),0.37(47.9% vs 63.8%,95% CI:0.19-0.71,P=0.003),and 0.32(66.7% vs 74.3%,95% CI:0.15-0.66,P=0.002),respectively;and the OR for the 1-,2-,3-,5-and 7-year mortality were 0.23(1.2% vs 9.1%,95% CI:0.07-0.71,P=0.01),0.31(6.4% vs 22.1%,95% CI:0.12-0.79,P=0.01),0.43(12.7% vs 20.8%,95% CI:0.21-0.89,P=0.02),0.42(25.1% vs 42.0%,95% CI:0.27-0.66,P=0.0002) and 0.28(31.9% vs 52.2%,95% CI:0.13-0.59,P=0.0008).CONCLUSION:This meta-analysis indicates the postoperative antiviral therapy,interferon in particular,may serve as a favorable alternative to reduce recurrence and mortality in patients with HBV/HCV related HCCs.Miao, Ruo-Yu Zhao, Hai-Tao Yang, Hua-Yu Mao, Yi-Lei Lu, Xin Zhao, Yi Liu, Chang-Ning Zhong, Shou-Xian Sang, Xin-Ting Huang, Jie-Fu 2010World Journal of Gastroenterology2010,16,23:26
12Relative Contributions of Boundary-Layer Meteorological Factors to the Explosive Growth of PM2.5 during the Red-Alert Heavy Pollution Episodes in Beijing in December 2016显示文摘Based on observations of urban mass concentration of fine particulate matter smaller than 2.5 μm in diameter(PM_(2.5)), ground meteorological data, vertical measurements of winds, temperature, and relative humidity(RH), and ECMWF reanalysis data, the major changes in the vertical structures of meteorological factors in the boundary layer(BL) during the heavy aerosol pollution episodes(HPEs) that occurred in winter 2016 in the urban Beijing area were analyzed. The HPEs are divided into two stages: the transport of pollutants under prevailing southerly winds, known as the transport stage(TS), and the PM_(2.5) explosive growth and pollution accumulation period characterized by a temperature inversion with low winds and high RH in the lower BL, known as the cumulative stage(CS). During the TS, a surface high lies south of Beijing, and pollutants are transported northwards. During the CS, a stable BL forms and is characterized by weak winds, temperature inversion, and moisture accumulation. Stable atmospheric stratification featured with light/calm winds and accumulated moisture(RH > 80%) below 250 m at the beginning of the CS is closely associated with the inversion, which is strengthened by the considerable decrease in near-surface air temperature due to the interaction between aerosols and radiation after the aerosol pollution occurs. A significant increase in the PLAM(Parameter Linking Aerosol Pollution and Meteorological Elements) index is found, which is linearly related to PM mass change. During the first 10 h of the CS, the more stable BL contributes approximately 84% of the explosive growth of PM_(2.5) mass. Additional accumulated near-surface moisture caused by the ground temperature decrease, weak turbulent diffusion, low BL height, and inhibited vertical mixing of water vapor is conducive to the secondary aerosol formation through chemical reactions, including liquid phase and heterogeneous reactions, which further increases the PM_(2.5) concentration levels. The contribution of these reaction mechanisms to the explosive growth of PM_(2.5) mass during the early CS and subsequent pollution accumulation requires further investigation.junting zhong xiaoye zhang yaqiang wang junying sun yangmei zhang jizhi wang kaiyan tan xiaojing shen haochi che lu zhang zhouxiang zhang xuefei qi huarong zhao sanxue ren yang li 2017Journal of Meteorological Research2017,31,5:25
13Aggregation-induced emission: a coming-of-age ceremony at the age of eighteen显示文摘Aggregation-induced emission(AIE) has drawn great attention worldwide for its unique optical phenomenon and huge potential applications. Since coined by Ben Zhong Tang et al. in 2001, AIE has been deeply investigated and widely utilized in many important areas, such as organic light-emitting diode(OLED), sensor, and bio-imaging. Herein, we highlight some important progress of AIE in these eighteen years, including the exploration of internal mechanism and potential applications. Furthermore,some other interestingly emissive behaviors, originating but distinguishing from the AIE concept, are presented. It is anticipated an overall understanding about AIE could be easily caught from this short review for scientists, no matter whether they are involved in this exciting and rising research area or not.Jie Yang Zhenguo Chi Weihong Zhu Ben Zhong Tang Zhen Li 2019Science China Chemistry2019,62,9:25
14Effect of Sancaijiangtang on plasma nitric oxide and endothelin-1 levels in patients with type 2 diabetes mellitus and vascular dementia:a single-blind randomized controlled trial显示文摘OBJECTIVE: To observe the effect of Sancaijiangtang powders on plasma nitric oxide and endothelin-1 levels. We sought to identify the common pathological link and mechanism of action for Traditional Chinese medicine in type 2 diabetes mellitus and vascular dementia,and to explicate the material basis for treating the different diseases with the same method in Traditional Chinese Medicine.METHODS: In total,168 patients with type 2 diabetes mellitus and vascular dementia were enrolled in the study,and randomly divided into two groups by simple randomization. Patients in the treatment group received oral Sancaijiangtang powders with pioglitazone hydrochloride three times daily,while patients in the control group received pioglitazone hydrochloride alone. The treatment course was for12 weeks. Mini-mental state examinations(Chinese version) and Montreal Cognitive Assessments(Beijing version) were performed,and fasting plasma glucose,fasting insulin,hemoglobin A1 c,homeostasis model assessment of insulin resistance,plasma nitric oxide and endothelin-1 levels were measured before and after the treatment.RESULTS: The post-treatment levels for all measurements in both groups were better than pre-treatment levels(P < 0.05). The post-treatment levels for all measurements in the treatment group were better than the levels measured in the control group(P < 0.05).CONCLUSION: Type 2 diabetes mellitus and vascular dementia have common pathological mechanisms for insulin resistance and endothelium dysfunction. Sancaijiangtang powders could improve the release of nitric oxide and inhibit the secretion of endothelin-1. Therefore,the material basis exists for treating the different diseases with the same method in Traditional Chinese Medicine.Guo Qiang Cao Wenzhai Zhao Huan Zhu Yuxia Yang Dongdong Zhong Sen Chen Qiu 2015Journal of Traditional Chinese Medicine2015,35,4:24

16Microwave photocatalytic degradation of Rhodamine B using TiO_2 supported on activated carbon:Mechanism implication显示文摘The photocatalytic degradation of Rhodamine B(RhB) was carried out using TiO2 supported on activated carbon(TiO2-AC) under microwave irradiation.Composite catalyst TiO2-AC was prepared and characterized using X-ray diffraction(XRD),transmission electron microscopy(TEM) and Brunauer-Emmett-Teller(BET).In the process of microwave-enhanced photocatalysis(MPC),RhB(30 mg/L) was almost completely decoloured in 10 min,and the mineralization effciency was 96.0% in 20 min.The reaction rate constant of RhB in MPC using TiO2-AC by pseudo first-order reaction kinetics was 4.16 times of that using Degussa P25.Additionally,according to gas chromatography/mass spectrometry(GC/MS) and liquid chromatography/mass spectrometry(LC/MS) identification,the major intermediates of RhB in MPC included two kinds of N-de-ethylation intermediates(N,N-diethyl-N'-ethyl-rhodamine(DER)),oxalic acid,malonic acid,succinic acid,and phthalic acid,maleic acid,3-nitrobenzoic acid,and so on.The degradation of RhB in MPC was mainly attributed to the destruction of the conjugated structure,and then the intermediates transformed to acid molecules which were mineralized to water and carbon dioxide.HE Zhong,YANG Shaogui,JU Yongming,SUN Cheng State Key Laboratory of Pollution Control and Resource Reuse,School of the Environment,Nanjing University,Nanjing 210093,China. 2009Journal of Environmental Sciences2009,21,2:22
17Assessment of selenium pollution in agricultural soils in the Xuzhou District,Northwest Jiangsu, China显示文摘Xuzhou City is an important base for coal production and coal-fired power. To evaluate selenium contamination in this area, we sampled agricultural soil, soil profile, irrigation water, bedrock, coal, fly ash, paddy rice, and vegetables from the north of Xuzhou City, and determined their selenium contents. The background level of selenium in the soil profile was 0.08 mg/kg. The selenium concentrations in agricultural soils and irrigation water were in the range of 0.21-4.08 mg/kg and 0.002-0.29 mg/L, respectively. Soils with high selenium content were located closely to coalmines and power plants. The average selenium concentrations in coal and coal fly ash were 5.46 and 2.81 mg/kg, respectively. In contrast, the concentrations of selenium in bedrock and in the soil profile were very low. These results imply that the high selenium level in agricultural soils is mainly caused by anthropogenic activities, rather than by parent material. The arithmetic mean of selenium concentration in paddy rice was 0.116 mg/kg, and in cabbage was 0.05 mg/kg. The selenium concentration in rice was positively correlated with total selenium concentration in soil, suggesting that selenium in soil is readily transferred into the crops. Furthermore, the estimated dietary intake (88.8 μg) of selenium from paddy rice and cabbage exceeds the recommended dietary allowance (55 μg). Therefore, there is a potential health risk from consumption of local staple food in the study area.HUANG Shunsheng HUA Ming FENG Jinshun ZHONG Xinyong JIN Yang ZHU Baiwan LU Hua 2009Journal of Environmental Sciences2009,21,4:22

19Bio-reduction of nitrate from groundwater using a hydrogen-based membrane biofilm reactor显示文摘A hydrogen-based membrane biofilm reactor(MBfR) using H2 as electron donor was investigated to remove nitrate from groundwater.When nitrate was first introduced to the MBfR,denitrification took place on the shell side of the membranes immediately,and the effluent concentration of nitrate continuously decreased with 100% removal rate on day 45 under the influent nitrate concentration of 5 mg NO3--N/L,which described the acclimating and enriching process of autohydrogenotrophic denitrification bacteria.A series of short-term experiments were applied to investigate the effects of hydrogen pressures and nitrate loadings on denitrification.The results showed that nitrate reduction rate improved as H2 pressure increasing,and over 97% of total nitrogen removal rate was achieved when the nitrate loading increased from 0.17 to 0.34 g NO3--N/(m2 ·day) without nitrite accumulation.The maximum denitrification rate was 384 g N/(m3 ·day).Partial sulfate reduction,which occurred in parallel to nitrate reduction,was inhibited by denitrififcation due to the competition for H2 .This research showed that MBfR is effective for removing nitrate from the contaminated groundwater.Siqing Xia Fohua Zhong Yanhao Zhang Haixiang Li Xin Yang 2010Journal of Environmental Sciences2010,22,2:23
