| 3 | The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity. | Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping | 2016 | Biomedical and Environmental Sciences2016，29，1： | 29 |
| 4 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021，41，11： | 29 |
| 5 | RNA-Seq analysis of yak ovary: improving yak gene structure information and mining reproduction-related genes显示文摘RNA-Seq,a high-throughput(HT)sequencing technique,has been used effectively in large-scale transcriptomic studies,and is particularly useful for improving gene structure information and mining of new genes.In this study,RNA-Seq HT technology was employed to analyze the transcriptome of yak ovary.After Illumina-Solexa deep sequencing,26826516 clean reads with a total of 4828772880 bp were obtained from the ovary library.Alignment analysis showed that 16992 yak genes mapped to the yak genome and 3734 of these genes were involved in alternative splicing.Gene structure refinement analysis showed that7340 genes that were annotated in the yak genome could be extended at the 5′or 3′ends based on the alignments been the transcripts and the genome sequence.Novel transcript prediction analysis identified 6321 new transcripts with lengths ranging from 180 to 14884 bp,and 2267 of them were predicted to code proteins.BLAST analysis of the new transcripts showed that1200?4933 mapped to the non-redundant(nr),nucleotide(nt)and/or SwissProt sequence databases.Comparative statistical analysis of the new mapped transcripts showed that the majority of them were similar to genes in Bos taurus(41.4%),Bos grunniens mutus(33.0%),Ovis aries(6.3%),Homo sapiens(2.8%),Mus musculus(1.6%)and other species.Functional analysis showed that these expressed genes were involved in various Gene Ontology(GO)categories and Kyoto Encyclopedia of Genes and Genomes pathways.GO analysis of the new transcripts found that the largest proportion of them was associated with reproduction.The results of this study will provide a basis for describing the normal transcriptome map of yak ovary and for future studies on yak breeding performance.Moreover,the results confirmed that RNA-Seq HT technology is highly advantageous in improving gene structure information and mining of new genes,as well as in providing valuable data to expand the yak genome information. | LAN DaoLiang XIONG XianRong WEI YanLi XU Tong ZHONG JinCheng ZHI XiangDong WANG Yong LI Jian | 2014 | Science China(Life Sciences)2014，57，9： | 23 |

| 7 | Phosphorus Status and Risk of Phosphate Leaching Loss From Vegetable Soils of Different Planting Years in Suburbs of Changsha, China显示文摘The aim of the study was to develop an index to assess the environmental risk of P loss potential in vegetable soils with chronic difference of plantation in the suburbs of Changsha, Hunan Province, China. Chemical methodology was used to study soil phosphorus status and the relationships between available P in soil and potential soil leaching P. The results showed that there was a significant linear relationship between Olsen P and CaCl2-P or P concentration in soil solution. Olsen P increased sharply when either CaCl2-P or P concentration in soil solution reached a certain level. It was confirmed that 80 mg kg-1 of Olsen P was the critical value of soil P leaching in the vegetable soils. P leaching probability over the critical was assessed by GIS and indicator Kriging and four secondary risks of phosphorus leaching loss were defined. In the area with vegetable cropping for over 30 yr (Chenjiadu) and 10-15 planting years (Huangxingzhen), the indices of phosphorus leaching loss risk were 3 and 2.93, respectively. These two areas belonged to strong secondary of risk of phosphate leaching loss. In the new vegetable planting field less than 2 yr (Ningxiang), the index was 0.06, which had almost no risk of phosphorus leaching. In vegetable soils in the suburban region of Changsha, the phosphorus leaching peotential is high and the phosphorus leaching loss is related to chronic length of vegetable cropping. | QIN Hong-ling QUAN Zhi LIU Xin-liang LI Ming-de ZONG Yong WU Jin-shui WEI Wen-xue | 2010 | Agricultural Sciences in China2010，9，11： | 15 |

| 9 | Seroepidemiological Investigation of Lyme Disease and Human Granulocytic Anaplasmosis among People Living in Forest Areas of Eight Provinces in China显示文摘Objective Lyme disease and Human granulocytic anaplasmosis are tick‐borne diseases caused by Borrelia burgdorferi and Anaplasma phagocytophilum respectively. We have investigated infection and co-infection of the two diseases in the population of forest areas of eight provinces in China by measuring seroprevalence of antibodies against B. burgdorferi and A. phagocytophilum. Methods Forest areas in 8 provinces were chosen for investigation using whole sampling and questionnaire survey methods. 3 669 serum samples from people in the forest areas were tested for the presence of antibodies by indirect immunofluorescent assay (IFA). Results Seroprevalence against B. burgdorferi was 3% to 15% and against A. phagocytophilum was 2% to 18% in the study sites in the 8 provinces in China. We also found co-infection of B. burgdorferi and A. phagocytophilum in 7 of the 8 provinces (the exception being the Miyun area in Beijing). The seroprevalence for both B. burgdorferi and A. phagocytophilum was significantly higher among people exposed to ticks than among people who were not exposed to ticks. Conclusion We conclude that both pathogens are endemic in the forest areas in the eight provinces, but the prevalence of B. burgdorferi and A. phagocytophilum differs between the provinces. | HAO Qin GENG Zhen HOU Xue Xia TIAN Zhen YANG Xiu Jun JIANG Wei Jia SHI Yan ZHAN Zhi Fei LI Guo Hua YU De Shan WANG Hua Yong XU Jian Guo WAN Kang Lin | 2013 | Biomedical and Environmental Sciences2013，26，3： | 13 |
| 10 | C-reactive Protein Level,Apolipoprotein B-to-apolipoprotein A-1 Ratio,and Risks of Ischemic Stroke and Coronary Heart Disease among Inner Mongolians in China显示文摘Objective We aimed to investigate the cumulative effect of high CRP level and apolipoprotein B-to-apolipoprotein A-1(ApoB/ApoA-1) ratio on the incidence of ischemic stroke(IS) or coronary heart disease(CHD) in a Mongolian population in China.Methods From June 2003 to July 2012,2589 Mongolian participants were followed up for IS and CHD events based on baseline investigation.All the participants were divided into four subgroups according to C-reactive protein(CRP) level and ApoB/ApoA-1 ratio.Cox proportional hazard models were used to estimate the hazard ratios(HRs) and 95% confidence intervals(CIs) for the IS and CHD events in all the subgroups.Results The HRs(95% CI) for IS and CHD were 1.33(0.84-2.12),1.14(0.69-1.88),and 1.91(1.17-3.11) in the ‘low CRP level with high ApoB/ApoA-1',‘high CRP level with low ApoB/ApoA-1',and ‘high CRP level with high ApoB/ApoA-1' subgroups,respectively,in comparison with the ‘low CRP level with low ApoB/ApoA-1' subgroup.The risks of IS and CHD events was highest in the ‘high CRP level with high ApoB/ApoA-1' subgroup,with statistical significance.Conclusion High CRP level with high ApoB/ApoA-1 ratio was associated with the highest risks of IS and CHD in the Mongolian population.This study suggests that the combination of high CRP and ApoB/ApoA-1 ratio may improve the assessment of future risk of developing IS and CHD in the general population. | TIAN Yun Fan ZHOU Yi Peng ZHONG Chong Ke BUREN Batu XU Tian LI Hong Mei ZHANG Ming Zhi WANG Ai Li ZHANG Yong Hong | 2016 | Biomedical and Environmental Sciences2016，29，7： | 12 |

| 12 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |

| 16 | Correlation of Seven Biological Factors(Hsp90α,p53,MDM2,Bcl-2,Bax,Cytochrome C,and Cleaved caspase3)with Clinical Outcomes of ALK+ Anaplastic Large-cell Lymphoma显示文摘Objective To explore correlation of seven apoptosis‐related proteins (Hsp90α,p53,MDM2,Bcl‐2,Bax,Cytochrome C,and Cleaved caspase3) with clinical outcomes of ALK+ anaplastic large‐cell lymphoma (ALCL).Methods Using immunohistochemistry and immunofluorescence double staining methods,the expressions of these seven apoptosis‐associated proteins were studied to clarify their relationship with clinical outcomes of 36 ALK+ and 25 ALK‐ systemic ALCL patients enrolled between 1996 and 2006.The relationship of these apoptosis‐regulating proteins with NPM‐ALK status was also evaluated with the tyrosine inhibitor herbimycin A (HA) in vitro by immunocytochemistry,Western blotting and flow cytometric assays.Results The presence of Hsp90α‐,MDM2‐,Bax‐,Cytochrome C,and Cleaved caspase3‐positive tumor cells was found significantly different in ALK+ and ALK‐ ALCLs ,which was correlated with highly favorable clinical outcome.The Bcl‐2‐ and p53‐positive tumor cells were found in groups of patients with unfavorable prognosis.Inhibition of NPM‐ALK by HA could reactivate the p53 protein and subsequent apoptosis‐related proteins and therefore induced apoptosis in ALK+ ALCL cells.Conclusion Our results suggest that these seven proteins might be involved in apoptosis regulation and associated with clinical outcome of ALK+ systemic ALCLs.We also reveal a dynamic chain relation that NPM‐ALK regulates p53 expression and subsequent apoptosis cascade in ALK+ ALCLs. | LI Hui Ling HUANG Xue Ping ZHOU Xin Hua JI Tian Hai WU Zi Qing WANG Zhi Qiang JIANG Hui Yong LIU Fan Rong ZHAO Tong | 2011 | Biomedical and Environmental Sciences2011，24，6： | 9 |
| 17 | Primary site and regional lymph nodeinvolvement are independent prognosticfactors for early?stage extranodal nasal?typenatural killer/T cell lymphoma显示文摘Background:Nasal-type extranodal natural killer/T-cell lymphoma(ENKTCL) originates primarily in the nasal cavity or extra-nasal sites within the upper aerodigestive tract.However,it is unclear whether the primary site can serve as an independent prognostic factor or whether the varying clinical outcomes observed with different primary sites can be attributed merely to their propensities of regional lymph node involvement.The aim of this study was to investigate the prognostic implications of the primary site and regional lymph node involvement in patients with early-stage nasal-type ENKTCL.Methods:To develop a nomogram,we reviewed the clinical data of 215 consecutively diagnosed patients with early-stage nasal-type ENKTCL who were treated in Sun Yat-sen University Cancer Center with chemotherapy and radiotherapy between 2000 and 2011.The predictive accuracy and discriminative ability of the nomogram were determined using a concordance index(C-index) and calibration curve.Results:The 5-year overall survival(OS) and progression-free survival(PFS) rates of patients with nasal ENKTCL were higher than those of patients with extra-nasal ENKTCL(OS:68.2%vs.46.0%,P = 0.030;PFS:53.4%vs.26.6%,P = 0.010).The 5-year OS and PFS rates of patients with Ann Arbor stage IE ENKTCL were higher than those of patients with Ann Arbor stage HE ENKTCL(OS:66.3%vs.59.2%,P = 0.003;PFS:51.4%vs.40.3%,P = 0.009).Multivariate analysis showed that age >60 years,ECOG performance status score >2,elevated lactate dehydrogenase(LDH) level,extranasal primary site,and regional lymph node involvement were significantly associated with lower 5-year OS rate;age >60 years,elevated LDH level,extra-nasal primary site,and regional lymph node involvement were significantly associated with lower 5-year PFS rate.The nomogram included the primary site and regional lymph node involvement based on multivariate analysis.The calibration curve showed good agreement between the predicted and actual 5-year OS and PFS rates,and the C-indexes of the nomogram for the OS and PFS rates were 0.697 and 0.634,respectively.Conclusions:The primary site and regional lymph node involvement are independent prognostic factors for earlystage ENKTCL treated with chemotherapy followed by definitive radiotherapy. | Shao‑Qing Niu Yong Yang Yi‑Yang Li Ge Wen Liang Wang Zhi‑Ming Li Han‑Yu Wang Lu‑Lu Zhang Yun‑Fei Xia Yu‑Jing Zhang | 2016 | Chinese Journal of Cancer2016，35，5： | 8 |
| 18 | Relationship 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 | 2019 | Biomedical and Environmental Sciences2019，32，5： | 8 |
| 19 | Screening of Serum Biomarkers for Distinguishing between Latent and Active Tuberculosis Using Proteome Microarray显示文摘Objective To identify potential serum biomarkers for distinguishing between latent tuberculosis infection(LTBI) and active tuberculosis(TB). Methods A proteome microarray containing 4,262 antigens was used for screening serum biomarkers of 40 serum samples from patients with LTBI and active TB at the systems level. The interaction network and functional classification of differentially expressed antigens were analyzed using STRING 10.0 and the TB database, respectively. Enzyme-linked immunosorbent assays(ELISA) were used to validate candidate antigens further using 279 samples. The diagnostic performances of candidate antigens were evaluated by receiver operating characteristic curve(ROC) analysis. Both antigen combination and logistic regression analysis were used to improve diagnostic ability. Results Microarray results showed that levels of 152 Mycobacterium tuberculosis(Mtb)-antigenspecific IgG were significantly higher in active TB patients than in LTBI patients(P < 0.05), and these differentially expressed antigens showed stronger associations with each other and were involved in various biological processes. Eleven candidate antigens were further validated using ELISA and showed consistent results in microarray analysis. ROC analysis showed that antigens Rv2031 c, Rv1408, and Rv2421 c had higher areas under the curve(AUCs) of 0.8520, 0.8152, and 0.7970, respectively. In addition, both antigen combination and logistic regression analysis improved the diagnostic ability. Conclusion Several antigens have the potential to serve as serum biomarkers for discrimination between LTBI and active TB. | CAO Shu Hui CHEN Yan Qing SUN Yong LIU Yang ZHENG Su Hua ZHANG Zhi Guo LI Chuan You | 2018 | Biomedical and Environmental Sciences2018，31，7： | 8 |
| 20 | Epidemiological 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 | 2017 | Biomedical and Environmental Sciences2017，30，7： | 7 |
