1The 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 2016Biomedical and Environmental Sciences2016,29,1:29
2Construction, expression and characterization of the engineered antibody against tumor surface antigen, p185^(c-erbB-2)显示文摘The c-erbB-2 proto-oncogene encodes a 185kDa protein p185, which belongs to epidermal growth factorreceptor family. Amplification of this gene has been shown to correlate with poor clinical prognosis forcertain cancer patients. The monoclonal antibody A21 which directed against p185 specifically inhibitsproliferation of tumor cells overexpressing p185, hence allows it to be a candidate for targeted therapy. Inorder to overcome several drawbacks of murine MAb, we cloned its VH and VL genes and constructed thesingle-chain Fv (scFv) through a peptide linker. The recombinant scFvA21 was expressed in Escherichiacoli and purified by the affinity column. Subsequently it was characterized by ELISA, Western blot, cellimmunohistochemistry and FACS. All these assays showed the binding activity to extracellular domain(ECD) of p185. Based on those properties of scFvA21, we further constructed the scFv-Fc fusion moleculewith a homodimer form and the recombinant product was expressed in mammalian cells. In a series ofsubsequent analysis this fusion protein showed identical antigen binding site and activity with the parentantibody. These anti-p185 engineered antibodies have promised to be further modified as a tumor targetingdrugs, with a view of application in the diagnosis and treatment of human breast cancer.LIAN SHENG CHENG, AI PING LIU, JIA HONG YANG, YAN QIU DONG, LIANG WEI LI, JING WANG, CHAO CHEN WANG, JING LIUSchool of Life Science, University of Science and Technology of China, Hefei 230027, China 2003Cell Research2003,13,1:24

4Pharmacokinetics of traditional Chinese syndrome and recipe:a hypothesis and its verification(Ⅰ)显示文摘AIM To propose a hypothesis defining theabsorption,distribution,metabolism andelimination of traditional Chinese recipe(TCR)-component in blood of healthy subjects andpatients,and estimate its correctness.METHODS The pharmacokinetics(PK)of samedose of drug was studied in the animal model oftraditional Chinese syndrome(S)and healthyanimals.The classification,terminology,concept and significance of the hypothesis wereset forth with evidence provided in the presentstudy.The hypotheses consisted of traditionalChinese syndrome PK(S-PK)and traditionalChinese recipe PK(R-PK).Firstly,the observedtetramethylpyrazine(TMP)PK in healthy,chronically reserpinized rats(rat model ofspleen deficiency syndrome,RMSDS)andRMSDS treated with Sijunzi decoction(SJZD)forconfirmation were used to verify S-PK; secondly,the ferulic acid(FA)PK in healthy andhigh molecular weight dextran(HMWD)-inducedrabbit model with blood stasis syndrome(RDBSS)was also used to verify S-PK;andlastly,TMP PK parameters in serum of healthyrats after orally taken Ligusticum wallichii(LW),LW and Salvia miltiorrhiza(LW&SM)decoctions were compared to verify R-PK.RESULTS The apparent first-order absorption[Ka,(13.61±2.56)h-1,area under the blooddrug concentration-time curve[AUC,(24.88±9.76)μg.h-1mL-1],maximum drug concentration[Cmax,(4.82±1.23)μg·mL-1]of serum TMP inRMSDS were increased markedly(P<0.05)compared with those[Ka=(5.41±1.91)h-1,AUC=(5.20±2.57)μg·h-1·mL-1,Cmax=(2.33±1.77)μg·mL-1]of healthy rats(HR).Theapparent first-order rate constant for α and βdistribution phase[α=(0.38±0.09)h-1,β=(0.06±0.03)h-1,the apparent first-orderintercompartmental transfer rate constants[K10=(0.24±0.07)h-1,K12=(0.11±0.02)h-1,K21=(0.11±0.02)h-1]of serum TMP in RMSDS weredecreased significantly(P<0.01)comparedwith those[K10=(0.88±0.20)h-1,K12=(1.45±0.47)h-1,K21=(0.72±0.22)h-1]of HR.However,no apparent differences occurredbetween HR and RMSDS treated with SJZD.Theserum FA concentration and its AUC[(5.6690±2.3541)μg·h-1·mL-1] in RMBSS were also higherthan those[AUC=(2.7566±0.8232)μg·h-1·mL-1]of healthy rabbits(P<0.05).The Ka(11.51±2.82)h-1,AUC(0.84±0.17)μg·h-1·mL-1of LW & SM-derived TMP in serum weremuch lower(P<0.05)than those[Ka=(19.58±4.14)h-1,AUC=(1.27±0.26)μg·h-1·mL-1]ofLW-derived TMP in serum after oral decoctions.CONCLUSION The SDS and blood stasissyndrome state could affect significantly thepharmacokinetic parameters of drugs and theabnormal SDS pharmacokinetic parameters couldbe normalized by SJZD.The combination ofChinese medicine in TCR could reciprocallyaffect the pharmacokinetic parameters of othercomponents absorbed into the systemiccirculation.These results support the S-and R-PK hypothesis.Xi Huang Ping Ren Ai Dong Wen Li Li Wang Li Zhang Feng Gao Laboratory of Clinical Pharmacology of Chinese Medicine,Xijing Hospital,The Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China Department of Pharmacy,Xijing Hospital,The Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China Department of Physiology,The Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China 2000World Journal of Gastroenterology2000,6,3:16
5Genotypic Characterization of Methicillin-resistant Staphylococcus aureus Isolated from Pigs and Retail Foods in China显示文摘Objective To investigate the genotypic diversity of Methicillin-resistant Staphylococcus aureus(MRSA) isolated from pigs and retail foods from different geographical areas in China and further to study the routes and rates of transmission of this pathogen from animals to food. Methods Seventy-one MRSA isolates were obtained from pigs and retail foods and then characterized by multi-locus sequencing typing(MLST), spa typing, multiple-locus variable number of tandem repeat analysis(MLVA), pulsed-field gel electrophoresis(PFGE), and antimicrobial susceptibility testing. Results All isolated MRSA exhibited multi-drug resistance(MDR). Greater diversity was found in food-associated MRSA(7 STs, 8 spa types, and 10 MLVA patterns) compared to pig-associated MRSA(3 STs, 1 spa type, and 6 MLVA patterns). PFGE patterns were more diverse for pig-associated MRSA than those of food-associated isolates(40 vs. 11 pulse types). Among the pig-associated isolates, CC9-ST9-t899-MC2236 was the most prevalent clone(96.4%), and CC9-ST9-t437-MC621(20.0%) was the predominant clone among the food-associated isolates. The CC9-ST9 isolates showed significantly higher antimicrobial resistance than other clones. Interestingly, CC398-ST398-t034 clone was identified from both pig-and food-associated isolates. Of note, some community-and hospital-associated MRSA strains(t030, t172, t1244, and t4549) were also identified as food-associated isolates. Conclusion CC9-ST9-t899-MC2236-MDR was the most predominant clone in pigs, but significant genetic diversity was observed in food-associated MRSA. Our results demonstrate the great need for improved surveillance of MRSA in livestock and food and effective prevention strategies to limit MDR-MRSA infections in China.WANG Wei LIU Feng ZULQARNAIN Baloch ZHANG Cun Shan MA Ke PENG Zi Xin YAN Shao Fei HU Yu Jie GAN Xin DONG Yin Ping BAI Yao LI Feng Qin YAN Xiao Mei MA Ai Guo XU Jin 2017Biomedical and Environmental Sciences2017,30,8:13

10Regulation of Survivin and CDK4 by Epstein-Barr virus encoded latent mem-brane protein 1 in nasopharyngeal carcinoma cell lines显示文摘Latent membrane protein 1 (LMP1), an important protein encoded by Epstein Barr virus (EBV), has been implied to link with the pathogenesis of nasopharyngeal carcinoma (NPC). Its dual effects of increasing cell proliferation and inhibiting cell apoptosis have been confirmed. In this study, we showed that the expression of Survivin and CDK4 protein in CNE-LMP1, a LMP1 positive NPC epithelial cell line, is higher than in LMP1 negative NPC epithelial cell line- CNE1, and the expression is LMP1 dosage-dependent. Although it was reported that Survivin specifically expressed in cell cycle G2/M phase, our studies suggested that LMP1 could promote the expression of Survivin in G0/G1, S and G2/ M phase. It also showed that Survivin and CDK4 could be accumulated more in the nuclei triggered by LMP1. More interestingly, Survivin and CDK4 could form a protein complex in the nuclei of CNE-LMP1 rather than in that of CNE1, which demonstrated that the interaction between these two proteins could be promoted by LMP1. These results strongly suggested that the role of LMP1 in the regulation of Survivin and CDK4 may also shed some light on the mechanism research of LMP1 in NPC.Mi Dan AI Li Li LI Xiao Rong ZHAO Yong WU Jian Ping GONG Ya CAO 2005Cell Research2005,15,10:8

12The preoperative serum cystatin-C as an independent prognostic factor for survival in upper tract urothelial carcinoma显示文摘Cystatin-C(Cys-C)has been reported as a valuable prognostic biomarker in various malignancies.However,its effect on upper tract urothelial carci noma(UTUC)patie nts has not bee n investigated before.Thus,to explore the impact of Cys-C on survival outcomes in patients undergoing radical nephroureterectomy(RNU),a total of 538 patients with UTUC who underwent RNU between 2005 and 2014 in our center(West China Hospital,Chengdu,China)were included in this study.Kaplan-Meier method and Cox regressi on an a lyses were performed to assess the relationship betwee n Cys-C and survival outcomes using SPSS versi on 22.0.The cutoff value of Cys-C was set as 1.4 mg I1 using the receiver operating characteristic(ROC)curves and Youden index.The mean age of patients included was 66.1±11.1 years,and the media n follow-up durati on was 38(interquartile ran ge:19-56)mon ths.Overall,162(30.1%)patients had elevated Cys-C,and they were much older and had worse renal function than those with Cys-C<1.4 mg I^-1(both P<0.001).Meanwhile,Kaplan-Meier analysis revealed that the group with elevated Cys-C had worse cancer-specific survival(CSS,P=0.001),disease recurrence-free survival(RFS,P=0.003),and overall survival(OS,P<0.001).Multivariable Cox analysis suggested that the elevated Cys-C was identified as an independent prognostic predictor of CSS(hazard ratio[HR]:1.997,95%confidential interval[CI]:1.331-2.996),RFS(HR:1.429,95%CI:1.009-2.023),and OS(HR:1.989,95%CI:1.366-2.896).In conclusion,our result revealed that the elevated preoperative serum Cys-C was significantly associated with worse outcomes in UTUC patients undergoing RNU.Ping Tan Ming Shi Jie Chen Hang Xu Nan Xie Huan Xu Yong Jiang Jian-Zhong Ai Liang-Ren Liu Lu Yang Qiang Wei 2019Asian Journal of Andrology2019,21,2:7
13Epidermal growth factor receptor mutation analysis in cytological specimens and responsiveness to gefitinib in advanced non-small cell lung cancer patients显示文摘Background: Epidermal growth factor receptor(EGFR) mutation is the key predictor of EGFR tyrosine kinase inhibitors(TKIs) efficacy in non-small cell lung cancer(NSCLC). We conducted this study to verify the feasibility of EGFR mutation analysis in cytological specimens and investigate the responsiveness to gefitinib treatment in patients carrying EGFR mutations.Methods: A total of 210 cytological specimens were collected for EGFR mutation detection by both direct sequencing and amplification refractory mutation system(ARMS). We analyzed EGFR mutation status by both methods and evaluated the responsiveness to gefitinib treatment in patients harboring EGFR mutations by overall response rate(ORR), disease control rate(DCR) and progression free survival(PFS).Results: Of all patients, EGFR mutation rate was 28.6%(60/210) by direct sequencing and 45.2%(95/210) by ARMS(P<0.001) respectively. Among the EGFR wild type patients tested by direct sequencing, 26.7% of them were positive by ARMS. For the 72 EGFR mutation positive patients treated with gefitinib, the ORR, DCR and median PFS were 69.4%, 90.2% and 9.3 months respectively. The patients whose EGFR mutation status was negative by direct sequencing but positive by ARMS had lower ORR(48.0% vs. 80.9%, P=0.004) and shorter median PFS(7.4 vs. 10.5 months, P=0.009) as compared with that of EGFR mutation positive patients by both detection methods. Conclusions: Our study verified the feasibility of EGFR analysis in cytological specimens in advanced NSCLC. ARMS is more sensitive than direct sequencing in EGFR mutation detection. EGFR Mutation status tested on cytological samples is applicable for predicting the response to gefitinib. Abundance of EGFR mutations might have an influence on TKIs efficacy.Lin Li Zijin Zhang Zhixin Bie Zheng Wang Ping Zhang Xin Nie Yuanming Li Hui Wang Bin Ai Gang Cheng 2015Chinese Journal of Cancer Research2015,27,3:5
14Estimating the Health and Economic Outcomes of the Prevention of Mother-to-child Transmission of HIV Using a Decision Tree Model显示文摘In 2016, there were 17.8 million (15.4-20.3 million) women living with HIV/AIDS across the world and the prevalence of reproductive desire among this group was 26%-49%[1]. If pregnant women living with HIV/AIDS are left untreated, the rates of HIV transmission from mother-to-child would range from 14% to 48%, depending on the presence and duration of breastfeeding[2].QU Shui Ling WANG Ai Ling PAN Xiao Ping WANG Qian DOU Li Xia ZHANG Tong 2019Biomedical and Environmental Sciences2019,32,1:4

17Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China.HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li 2014Biomedical and Environmental Sciences2014,27,5:3
18Chirality-assisted lateral momentum transfer for bidirectional enantioselective separation显示文摘Lateral optical forces induced by linearly polarized laser beams have been predicted to deflect dipolar particles with opposite chiralities toward opposite transversal directions.These“chirality-dependent”forces can offer new possibilities for passive all-optical enantioselective sorting of chiral particles,which is essential to the nanoscience and drug industries.However,previous chiral sorting experiments focused on large particles with diameters in the geometrical-optics regime.Here,we demonstrate,for the first time,the robust sorting of Mie(size~wavelength)chiral particles with different handedness at an air–water interface using optical lateral forces induced by a single linearly polarized laser beam.The nontrivial physical interactions underlying these chirality-dependent forces distinctly differ from those predicted for dipolar or geometrical-optics particles.The lateral forces emerge from a complex interplay between the light polarization,lateral momentum enhancement,and out-of-plane light refraction at the particle-water interface.The sign of the lateral force could be reversed by changing the particle size,incident angle,and polarization of the obliquely incident light.Yuzhi Shi Tongtong Zhu Tianhang Zhang Alfredo Mazzulla Din Ping Tsai Weiqiang Ding Ai Qun Liu Gabriella Cipparrone Juan Jose Saenz Cheng-Wei Qiu 2020Light(Science & Applications)2020,9,1:3
19Trans Fatty Acid Levels in Foods and Intakes among Population Aged 3 Years and above in Beijing and Guangzhou Cities,China显示文摘Objective To understand the dietary intake levels of trans fatty acids(TFA) in a Chinese population and establish a basis for health risk assessment of trans fatty acids. Methods The TFA contents data of 2613 food items and food consumption data of 10,533 people aged 3 years and above in two large cities in China were matched and a simple assessment method was used to estimate the distribution of dietary TFA intake. Results The mean content of TFA was highest in margarine(1.68±0.83 g/100g), followed by chocolate and candy(0.89±2.68 g/100g), edible vegetable oils(0.86±0.82 g/100g), milk(0.83±1.56 g/100g), and bakery foods(0.41±0.91 g/100g). TFA intake accounted for 0.34%, 0.30%, 0.32%, and 0.29% of the total energy intake in the 3-6, 7-12, 13-17, and ≥18 year age groups, respectively. Of the populations studied, 0.42% demonstrated TFA intakes(as percentage of energy intake) greater than 1%. The main sources of dietary TFA intake were edible vegetable oils, milk, mutton, and beef, and baked foods, which accounted for 49.8%, 16.56%, 12.21%, and 8.87%, respectively. Conclusion The current intake of TFA among people in two cities did not appear to be of major health concern regarding the threshold of TFA intake as the percentage of total energy recommended by the World Health Organization. Because most TFA were derived from industrially processed foods, the government should reinforce nutrition labeling and regulate food producers to further reduce TFA in food and to provide scientific instruction for consumers to make sound choices.LIU Ai Dong LI Jian Wen LIU Zhao Ping ZHOU Ping Ping MAO Wei Feng LI Ning ZHANG Lei 2015Biomedical and Environmental Sciences2015,28,7:3
