2Apoptosis and Proinflammatory Cytokine Responses of Primary Mouse Microglia and Astrocytes Induced by Human H1N1 and Avian H5N1 Influenza Viruses显示文摘Patients with an influenza virus infection can be complicated by acute encephalopathy and encephalitis. To investigate the immune reactions involved in the neurocomplication,mouse microglia and astrocytes were isolated,infected with human H1N1 and avian H5N1 influenza viruses,and examined for their immune responses. We observed homogeneously distributed viral receptors,sialic acid (SA)-α2,3-Galactose (Gal) and SA-α2,6-Gal,on microglia and astrocytes. Both viruses were replicative and productive in microglia and astrocytes. Virus-induced apoptosis and cytopathy in infected cells were observed at 24 h post-infection (p.i.). Expression of IL-1β,IL-6 and TNF-α mRNA examined at 6 h and 24 h p.i. was up-regulated,and their expression levels were considerably higher in H5N1 infection. The amounts of secreted proinflammatory IL-1β,IL-6 and TNF-α at 6 h and 24 h p.i. were also induced,with greater induction by H5N1 infection. This study is the first demonstration that both human H1N1 and avian H5N1 influenza viruses can infect mouse microglia and astrocytes and induce apoptosis,cytopathy,and proinflammatory cytokine production in them in vitro. Our results suggest that the direct cellular damage and the consequences of immunopathological injury in the CNS contribute to the influenza viral pathogenesis.Gefei Wang Juan Zhang Weizhong Li Yun Su Yuanli Gao Heng Zhang Guimei Lin Xiaoyang Jiao Kangsheng Li 2008Cellular & Molecular Immunology2008,5,2:28
3Traditional Chinese medicine integrated with chemotherapy for stage Ⅳ non-surgical gastric cancer: a retrospective clinical analysis显示文摘OBJECTIVE: Traditional Chinese medicine(TCM) is regarded as an important treatment for gastric cancer patients, especially for those in advanced stage. To evaluate the effects of TCM treatment on gastric cancer patients, the authors performed a retrospective study to report the result of the integrated treatment of TCM with chemotherapy for stage IV non-surgical gastric cancer.METHODS: In this study, 182 patients with stage IV and non-surgical gastric cancer were retrospectively analyzed to evaluate the effects of TCM integrated with chemotherapy. Among the 182 cases, 88 cases received integrated therapy consisting of TCM and chemotherapy, while 94 cases received chemotherapy alone. The overall survival and Karnofsky performance status(KPS) score were measured as the main outcome.RESULTS: The median overall survival of the integrated therapy group and chemotherapy group were 16.9 and 10.5 months, respectively. The 1-, 3-and 5-year survival rates of integrated therapy group vs. chemotherapy group were 70% vs. 32%, 18% vs. 4%, and 11% vs. 0%, respectively. There was a significant difference between the two groups(χ2 = 42.244, P < 0.001). After six-month treatment, KPS scores of the integrated therapy group and the chemotherapy group were 75.00 ± 14.78 and 60.64 ± 21.39, respectively(P < 0.001). The Cox regression analysis showed that TCM treatment is a protective factor for patients' overall survival. CONCLUSION: This study demonstrated that TCM integrated with chemotherapy may prolong overall survival and improve survival rate and life quality of patients with stage IV non-surgical gastric cancer.xuan liu li-juan xiu jian-peng jiao jing zhao ying zhao ye lu jun shi yong-jin li min ye yu-fang gu xiao-wei wang jing-yu xu ci-an zhang yong-ying liu yun luo xiao-qiang yue 2017Journal of Integrative Medicine2017,15,6:18
4The Chromosome-Based Rubber Tree Genome Provides New Insights into Spurge Genome Evolution and Rubber Biosynthesis显示文摘The rubber tree,Hevea brasiliensis,produces natural rubber that serves as an essential industrial raw material.Here,we present a high-quality reference genome for a rubber tree cultivar GT1 using single-molecule real-time sequencing(SMRT)and Hi-C technologies to anchor the~1.47-Gb genome assembly into 18 pseudochromosomes.The chromosome-based genome analysis enabled us to establish a model of spurge chromosome evolution,since the common paleopolyploid event occurred before the split of Hevea and Manihot.We show recent and rapid bursts of the three Hevea-specific LTR-retrotransposon families during the last 10 million years,leading to the massive expansion by~65.88%(~970 Mbp)of the whole rubber tree genome since the divergence from Manihot.We identify large-scale expansion of genes associated with whole rubber biosynthesis processes,such as basal metabolic processes,ethylene biosynthesis,and the activation of polysaccharide and glycoprotein lectin,which are important properties for latex production.A map of genomic variation between the cultivated and wild rubber trees was obtained,which contains~15.7 million high-quality single-nucleotide polymorphisms.We identified hundreds of candidate domestication genes with drastically lowered genomic diversity in the cultivated but not wild rubber trees despite a relatively short domestication history of rubber tree,some of which are involved in rubber biosynthesis.This genome assembly represents key resources for future rubber tree research and breeding,providing novel targets for improving plant biotic and abiotic tolerance and rubber production.Jin Liu Cong Shi Cheng-Cheng Shi Wei Li Qun-Jie Zhang Yun Zhang Kui Li Hui-Fang Lu Chao Shi Si-Tao Zhu Zai-Yun Xiao Hong Nan Yao Yue Xun-Ge Zhu Yu Wu Xiao-Ning Hong Guang-Yi Fan Yan Tong Dan Zhang Chang-Li Mao Yun-Long Liu Shi-Jie Hao Wei-Qing Liu Mei-Qi Lv Hai-Bin Zhang Yuan Liu Ge-Ran Hu-tang Jin-Peng Wang Jia-Hao Wang Ying-Huai Sun Shu-Bang Ni Wen-Bin Chen Xing-Cai Zhang Yuan-Nian Jiao Evan E.Eichler Guo-Hua Li Xin Liu Li-Zhi Gao 2020Molecular Plant2020,13,2:15
5Neuroprotective Autophagic Flux Induced by Hyperbaric Oxygen Preconditioning is Mediated by Cystatin C显示文摘We have previously reported that Cystatin C(CysC) is a pivotal mediator in the neuroprotection induced by hyperbaric oxygen(HBO) preconditioning; however,the underlying mechanism and how CysC changes after stroke are not clear. In the present study, we demonstrated that CysC expression was elevated as early as 3 h after reperfusion, and this was further enhanced by HBO preconditioning. Concurrently, LC3-II and Beclin-1, two positive-markers for autophagy induction, exhibited increases similar to CysC, while knockdown of CysC blocked these elevations. As a marker of autophagy inhibition, p62 was downregulated by HBO preconditioning and this was blocked by CysC knockdown. Besides, the beneficial effects of preserving lysosomal membrane integrity and enhancing autolysosome formation induced by HBO preconditioning were abolished in CysC-/-rats.Furthermore, we demonstrated that exogenous CysC reduced the neurological deficits and infarct volume after brain ischemic injury, while 3-methyladenine partially reversed this neuroprotection. In the present study, we showed that CysC is biochemically and morphologically essential for promoting autophagic flux, and highlighted the translational potential of HBO preconditioning and CysC for stroke treatment.Zongping Fang Yun Feng Yuheng Li Jiao Deng Huang Nie Qianzhi Yang Shiquan Wang Hailong Dong Lize Xiong 2019Neuroscience Bulletin2019,35,2:14
6Protective Effects of Chaihu Shugan San(柴胡疏肝散) on Nonalcoholic Fatty Liver Disease in Rats with Insulin Resistance显示文摘Objective: To investigate the protective effects of Chinese medicine formulation Chaihu Shugan San(柴胡疏肝散, CHSGS) on nonalcoholic fatty liver disease(NAFLD) in rats with insulin resistance(IR) and its molecular mechanisms. Methods: Male Sprague-Dawley rats were randomly divided into six groups: the control group, the model group, Dongbao Gantai group(东宝肝泰, DBGT, 0.09 g methionine/kg), CHSGS high-dose group(CHSG-H, 12.6 g crude drug/kg), CHSGS medium-dose group(CHSG-M, 6.3 g crude drug/kg), and CHSGS low-dose group(CHSG-L, 3.15 g crude drug/kg). After establishing the NAFLD rat model and treatment for 8 weeks, total cholesterol(TC), triglyceride(TG), high-density lipoprotein cholesterol(HDL-C), free fatty acid(FFA), fasting blood glucose(FBG), fasting insulin(FINS) contents in blood serum, and TC, TG contents in the hepatic homogenate were measured by an automatic biochemical analyzer, and a homeostasis model assessment was applied to assess the status of IR, insulin sensitivity index(ISI), and homeostasis model assessment for insulin secretion(HOMA-IS). The expression levels of adiponectin and leptin mRNA in liver tissue were analyzed by reverse transcription polymerase chain reaction. Pathological changes of livers were observed by hematoxylineosin staining of paraffin section. Results: Compared with the model group, the serum levels of TC, TG, FFA, FBG, FINS, IRI, ISI, and the liver levels of TC and TG in CHSG-H, CHSG-M, CHSG-L groups showed significant declines(P<0.01 or P<0.05); the serum levels of HDL-C, HOMA-IS were significantly increased(P<0.01 or P<0.05); the expression of leptin mRNA was dramatically decreased and the expression of adiponectin mRNA was increased in the hepatic tissue(P<0.01 or P<0.05). The fatty deposition of liver cells could also be alleviated. Conclusion: CHSGS could up-regulate the expression of adiponectin mRNA and down-regulate the expression of leptin mRNA on the liver, suggesting the CHSGS had positive therapeutic effect on NAFLD in rats with IR.JIANG Wei-ning LI Dan JIANG Tao GUO Jiao CHEN Yan-fen WANG Jie ZHOU Yun YANG Chao-yan TANG Chun-ping 2018Chinese Journal of Integrative Medicine2018,24,2:10
7Construction of an anchoring SSR marker genetic linkage map and detection of a sex-linked region in two dioecious populations of red bayberry显示文摘Red bayberry(Morella rubra)is an evergreen fruit tree found in southern China whose whole-genome sequence has recently been published.We updated the linkage map of the species by adding 118 SSR markers and the femalespecific marker MrFT2_BD-SEX.The integrated map included eight linkage groups and spanned 491 cM.Eleven sexassociated markers were identified,six of which were located in linkage group 8,in agreement with the previously reported location of the sex-determining region.The MrFT2_BD-SEX marker was genotyped in 203 cultivated accessions.Among the females of the accessions,we found two female-specific alleles,designated W-b(151 bp)and W-d(129 bp).We previously found that‘Dongkui’,a female cultivar,could produce viable pollen(we refer to such plants‘Dongkui-male’)and serve as the paternal parent in crosses.The genotypes of the MrFT2_BD-SEX marker were W-b/Z in‘Biqi’and W-d/Z in‘Dongkui-male’.The progeny of a cross between these parents produced a 3:1 female(W-)to male(ZZ)ratio and the expected 1:1:1:1 ratio of W-b/W-d:W-b/Z:W-d/Z:Z/Z.In addition,the flowering and fruiting phenotypes of all the F1 progeny fit their genotypes.Our results confirm the existence of ZW sex determination and show that the female phenotype is controlled by a single dominant locus(W)in a small genomic region(59 kb and less than 3.3 cM).Furthermore,we have produced a homozygous“super female”(WW)that should produce all-female offspring in the F2 generation,providing a foundation for commercial use and presenting great potential for use in modern breeding programs.Yan Wang Hui-Min Jia Yu-Tong Shen Hai-Bo Zhao Qin-Song Yang Chang-Qing Zhu De-Li Sun Guo-Yun Wang Chao-Chao Zhou Yun Jiao Chun-Yan Chai Li-Ju Yan Xiong-Wei Li Hui-Juan Jia Zhong-Shan Gao 2020Horticulture Research2020,7,1:10
8Effect of Sanhuangwuji powder,anti-rheumatic drugs,and ginger-partitioned acupoint stimulation on the treatment of rheumatoid arthritis with peptic ulcer:a randomized controlled study显示文摘OBjECTIVE:To observe the efficacy and safety of oral Sanhuangwuji powder,anti-rheumatic drugs(ARDs),and ginger-partitioned acupoint stimulation at Zusanli(ST 36) on the treatment of rheumatoid arthritis(RA) complicated by peptic ulcer.METHODS:This prospective randomized controlled study included 180 eligible inpatients and outpatients randomly assigned to an ARD treatment(n = 60),ginger-partitioned stimulation(n =60),or combination treatment(n = 60).Patients assigned to the ARD group were given oral celecoxib,methotrexate,and esomeprazole.Patients assigned to theginger-partitioned stimulation group were given ginger-partitioned acupoint stimulation at Zusanli(ST 36) in addition to the ARDs.Patients in the combination treatment group were given oral Sanhuangwuji powder,ginger-partitioned acupoint stimulation at Zusanli(ST 36),and ARDs.All patients were followed up for 2 months to evaluate clinical effects and safety.The study was registered in the World Health Organization database at the General Hospital of Chengdu Military Area Command Chinese People's Liberation Army(ChiCTR-TCC12002824).RESULTS:The combination treatment group had significantly greater improvements in RA symptoms,laboratory outcomes,and gastrointestinal symptom scores,compared with the other groups(P < 0.05).The peptic ulcer healing rate in the combination treatment group was significantly greater than that in the ARD treatment group(x^2 = 16.875,P < 0.05) and the ginger-partitioned stimulation group(x^2 = 6.171,P<0.05).CONCLUSION:Combination treatment with ginger-partitioned acupoint stimulation at Zusanli(ST36),oral Sanhuangwuji powder,and ARDs had a better clinical effect for RA with complicated peptic ulcer,compared with ARD treatmentalone or in combination with ginger-partitioned acupoint stimulation.Liu Defang Guo Mingyang Hu Yonghe Liu Taihua Yan Jiao Luo Yong Yun Mingdong Yang Min Zhang Jun Guo Linglin 2015Journal of Traditional Chinese Medicine2015,35,3:9

10MAV/UAV task coalition phased-formation method显示文摘The formation of the manned aerial vehicle/unmanned aerial vehicle(MAV/UAV) task coalition is considered. To reduce the scale of the problem, the formation progress is divided into three phases. For the task clustering phase, the geographical position of tasks is taken into consideration and a cluster method is proposed. For the UAV allocation phase, the UAV requirement for both constrained and unconstrained resources is introduced, and a multi-objective optimal algorithm is proposed to solve the allocation problem. For the MAV allocation phase, the optimal model is firstly constructed and it is decomposed according to the ideal of greed to reduce the time complexity of the algorithm. Based on the above phases, the MAV/UAV task coalition formation method is proposed and the effectiveness and practicability are demonstrated by simulation examples.JIAO Zhiqiang YAO Peiyang ZHANG Jieyong ZHONG Yun WANG Xun 2019Journal of Systems Engineering and Electronics2019,30,2:8
11New insight into adsorption characteristics and mechanisms of the biosorbent from waste activated sludge for heavy metals显示文摘The adsorption characteristics and mechanisms of the biosorbent from waste activated sludge were investigated by adsorbing Pb2+and Zn2+in aqueous single-metal solutions. A p H value of the metal solutions at 6.0 was beneficial to the high adsorption quantity of the biosorbent. The optimal mass ratio of the biosorbent to metal ions was found to be 2. A higher adsorption quantity of the biosorbent was achieved by keeping the reaction temperature below 55°C. Response surface methodology was applied to optimize the biosorption processes, and the developed mathematical equations showed high determination coefficients(above 0.99 for both metal ions) and insignificant lack of fit(p = 0.0838 and 0.0782 for Pb2+and Zn2+, respectively). Atomic force microscopy analyses suggested that the metal elements were adsorbed onto the biosorbent surface via electrostatic interaction. X-ray photoelectron spectroscopy analyses indicated the presence of complexation(between –NH2,-CN and metal ions) and ion-exchange(between –COOH and metal ions). The adsorption mechanisms could be the combined action of electrostatic interaction, complexation and ion-exchange between functional groups and metal ions.Yun Zhou Zhiqiang Zhang Jiao Zhang Siqing Xia 2016Journal of Environmental Sciences2016,28,7:7

13Geochemical characteristics and tectonic setting of the Middle Permian Tiaohu Formation mafic-ultramafic rocks of Santanghu area, Xinjiang, Northwest China显示文摘Santanghu area in northeastern Xinjiang region of Northwest China is an important component of the Central Asian Orogenic Belt(CAOB), in which the dynamic mechanism of Permian magmatism is controversial. In Santanghu area is exposed a thick succession of the Middle Permian basalts, including a small amount of picritic basalts and andesites, known as the Tiaohu Formation. The picritic basalts contain cumulate olivine, and have whole-rock Mg# up to 0.68–0.77; the basalts exhibit porphyritic or doleritic textures, and have relatively low Mg# of 0.41–0.54, typical of evolved magmas. The mafic-ultramafic rocks of the Tiaohu Formation are slightly enriched in Light Rare Earth Elements(LREEs), and exhibit negative Nb and Ti anomalies. They also have high Ti O2 content, and Nb/Y and Zr/Yb ratios greater than those of island arc volcanic rocks. Relatively low initial Sr isotopic ratios and high positive εNd(t) and εHf(t) values argue against contamination by ancient continental crust, and suggest formation of the Tiaohu Formation by partial melting of relatively refractory depleted lithospheric mantle that underwent metasomatism and extraction by fluid from the subducted slab. In addition, up to 38% olivine in picritic basalts indicates high-degree partial melting of lithospheric mantle, and the underlying Lucaogou Formation contains fragments of ultra-alkaline magmatic rocks that originated in the deep mantle. These observations imply wide-spread underplating in Santanghu area, which may have been associated with a mantle plume.WANG ShuangShuang LIU YiQun ZHANG HongFu ZHOU DingWu JIAO Xin NAN Yun 2015Science China Earth Sciences2015,58,11:7
14Quantitative Simulation on Soil Moisture Contents of Two Typical Vegetation Communities in Sanjiang Plain,China显示文摘Different types of vegetation occupy different geomorphology and water gradient environments in the San-jiang Plain,indicating that the soil moisture dynamics and water balance patterns of the different vegetation communi-ties might differ from each other.In this paper,a lowland system,perpendicular to the Nongjiang River in the Honghe National Nature Reserve(HNNR),was selected as the study area.The area was occupied by the non-wetland plant forest and the typical wetland plant meadow.The Microsoft Windows-based finite element analysis software package for simulating water,heat,and solute transport in variably saturated porous media(HYDRUS),which can quantita-tively simulate water,heat,and/or solute movement in variably-saturated porous media,was used to simulate soil moisture dynamics in the root zone(20-40 cm) of those two plant communities during the growing season in 2005.The simulation results for soil moisture were in a good agreement with measured data,with the coefficient of determi-nation(R2) of 0.44-0.69 and root mean square error(RMSE) ranging between 0.0291 cm3/cm3 and 0.0457 cm3/cm3,and index of agreement(d) being from 0.612 to 0.968.During the study period,the volumetric soil moisture content of meadow increased with the depth and its coefficient of variation decreased with the depth(from 20 cm to 40 cm),while under the forest the soil moisture content at different depths varied irregularly.The calculated result of water budget showed that the water budget deficit of the meadow was higher than that of the forest,suggesting that the meadow is more likely to suffer from water stress than the forest.The quantitative simulation by HYDRUS in this study did not take surface runoff and plant growth processes into account.Improved root water uptake and surface runoff models will be needed for higher accuracy in further researches.LI Shanghua ZHOU Demin LUAN Zhaoqing PAN Yun JIAO Cuicui 2011Chinese Geographical Science2011,21,6:7
15Salvianolic acids improve liver lipid metabolism in ovariectomized rats via blocking STAT-3/SREBP1 signaling显示文摘Postmenopausal women, who have reduced circulating estrogen levels, are more prone to develop obesity and related metabolic diseases than premenopausal women. The absence of safe and effective treatments for postmenopausal obesity has changed the focus to natural products as alternative remedies. Total salvianolic acids(TSA) are the major water-soluble ingredients of Danshen. Salvianolic acid(SA) is the major constituent of the TSA. Salvianolic acids, including TSA and SA, are widely used in traditional Chinese medicine. In the present study, ovariectomized rats and LO2 cells were used to study the effects of salvianolic acids on body weight gain and hepatic steatosis. Salvianolic acids reduced ovariectomy(OVX)-induced body weight gain, attenuated the expressions of hepatic lipogenic genes, such as sterol regulatory element binding protein(SREBP)1, fatty acid synthase(FAS), and stearoyl-CoA desaturase(SCD)1, and decreased the liver triglyceride(TG) and total cholesterol(TC). For the molecular mechanisms, OVX and high glucose-induced phosphorylation of signal transducer and activator of transcription(STAT)-3 was inhibited by salvianolic acids treatment. In LO2 cells, inhibition of STAT-3 by siRNA attenuated the increased expression of SREBP1 and TG induced by high glucose. Salvianolic acids reduced the upregulation of SREBP1 and TG induced by high glucose in LO2 cells. In conclusion, these findings illustrated that salvianolic acids markedly alleviated the lipid metabolism disorders and protected against the postmenopausal obesity. The underlying mechanism was probably associated with the regulation of STAT-3 signaling.CHEN Juan YUE Jia LIU Jiao LIU Yun JIAO Kai-Lin TENG Meng-Ying HU Chun-Yan ZHEN Jing WU Mao-Xuan ZHOU Ming LI Zhong LI Yuan 2018Chinese Journal of Natural Medicines2018,16,11:6
16Catalytic activity of Cu-SSZ-13 prepared with different methods for NH_3-SCR reaction显示文摘A series of Cu-SSZ-13 catalysts with the same Cu loading were prepared by different methods of incipient wetness impregnation [Cu-SSZ-13(IWI)], ion exchange[Cu-SSZ-13(IE)] and hydro-thermal synthesis [Cu-SSZ-13(HTS)]. Their activity for selective catalytic reduction of nitrogen oxides(NO_x) with NH3 was determined. The results show that the Cu-SSZ-13(HTS) catalyst exhibits a better ammonia selective catalytic reduction(NH3-SCR)activity compared with the other two catalysts, over which more than 90% NO conversion is obtained at 215-600℃under the space velocity of 180,000 h^(-1). The characterization results reveal that the Cu-SSZ-13(HTS) catalyst possesses more amount of stable Cu^(2+) in the six-membered ring and high ability for NH3 and NO adsorption, leading to its high NH3-SCR activity, although this catalyst has low surface area. On the other hand, the activity of Cu-SSZ-13(IE) catalyst is almost the same as that of Cu-SSZ-13(IWI) catalyst at the temperature lower than 400 ℃, but the activity of the former is much higher than that of the latter at > 400 ℃ due to the high activity of Cu-SSZ-13(IWI) catalyst for NH3 oxidation.Meng-Jie Han Yun-Lei Jiao Chun-Hong Zhou Yang-Long Guo Yun Guo Guan-Zhong Lu Li Wang Wang-Cheng Zhan 2019Rare Metals2019,38,3:6
17Dynamic model for sucking process of pneumatic cutting-type safflower harvest device显示文摘This study proposed a method using negative pressure sucking the petals adhered around cones.The structural parameters of the sucking device affect the flow-field distribution in the negative-pressure air chamber.In order to improve the harvesting efficiency and quality of the pneumatic cutting-type safflower harvest device,a dynamic model was established and the safflower petals upwind area were measured.According to the test,the size parameters of the thornless Yumin safflower were as follows:the average necking diameter was 6.30 mm,the average capitulum diameter was 20.89 mm and the average petal length was 22.39 mm.The measured maximum frontal area of the safflower petal was 11-40 mm2.Secondly,the required negative pressure power that resulted in the rise of safflower petals was calculated.In general,when the suction of the negative pressure reaches 9.8 m/s,the safflower petals can be sucked successfully.The simulation of the flow field in the suction mouth indicated that the streamlined suction mouth was beneficial in reducing resistance and the test results of high-speed photography showed that the aforementioned condition could improve the efficiency of the upright safflower.And the test verified that the rate of the unshaped petals in the cylindrical air tunnel was low and the efficiency of carding and shaping under negative pressure was considerably better in wet petals than in dry ones.Results of the upright safflower petal experiment were consistent with the theoretical analysis and simulation conclusion,and indicated the precision of the dynamic model and suction flower mouth orifice-shaped simulation analysis.Ge Yun Zhang Lixin Qian Ying Jiao Xiaopan Chen Yuanbo 2016International Journal of Agricultural and Biological Engineering2016,9,5:6

19Maternal Disononyl Phthalate Exposure Activates Allergic Airway Inflammation via Stimulating the Phosphoinositide 3-kinase/Akt Pathway in Rat Pups显示文摘Objective To evaluate the effect of diisononyl phthalate(DINP) exposure during gestation and lactation on allergic response in pups and to explore the role of phosphoinositide 3-kinase/Akt pathway on it. Methods Female Wistar rats were treated with DINP at different dosages(0, 5, 50, and 500 mg/kg of body weight per day). The pups were sensitized and challenged by ovalbumin(OVA). The airway response was assessed; the airway histological studies were performed by hematoxylin and eosin(HE) staining; and the relative cytokines in phosphoinositide 3-kinase(PI3K)/Akt pathway were measured by enzyme-linked immunosorbent assay(ELISA) and western blot analysis. Results There was no significant difference in DINP's effect on airway hyperresponsiveness(AHR) between male pups and female pups. In the 50 mg/(kg·d) DINP-treated group, airway response to OVA significantly increased and pups showed dramatically enhanced pulmonary resistance(RI) compared with those from controls(P<0.05). Enhanced Akt phosphorylation and NF-κB translocation, and Th2 cytokines expression were observed in pups of 50 mg/(kg·d) DINP-treated group. However, in the 5 and 500 mg/(kg·d) DINP-treated pups, no significant effects were observed. Conclusion There was an adjuvant effect of DINP on allergic airway inflammation in pups. Maternal DINP exposure could promote OVA-induced allergic airway response in pups in part by upregulation of PI3K/Akt pathway.CHEN Li CHEN Jiao XIE Chang Ming ZHAO Yan WANG Xiu ZHANG Yun Hui 2015Biomedical and Environmental Sciences2015,28,3:5
