2Outbreak of Dengue Fever in Central China,2013显示文摘In 2013,the first dengue fever(DF) outbreak in central China was reported in the central of Henan province,northern temperate regions,although they have been sequentially recorded in Southern China.106 suspected DF cases were reported and 73 patients were confirmed dengue virus type 3(DEN-3) infections.62/392(15.8%) local health persons showed DEN antibodies positive.To this day Henan is the northernmost province in China which has been reported about outbreak of DF and what is important is that it warns us the endemic range of DF has been expanded geographically in China.HUANG Xue Yong MA Hong Xia WANG Hai Feng DU Yan Hua SU Jia LI Xing Le TANG Xiao Yan MA Hong Peng ZU Bing Can ZHANG Qiao Hong CHEN Hao Min XU Bian Li 2014Biomedical and Environmental Sciences2014,27,11:30
3Changed clinical aspects of primary liver cancer in China during the past 30 years显示文摘BACKGROUND: Primary liver cancer (PLC) is one of the most frequently seen tumors in China. Thirty years ago, patients with PLC were often detected at relatively late stage, with a palpable mass or marked clinical symptoms and poor prognosis. In the past 30 years, the diagnosis and treatment of PLC have been greatly improved with better prognosis. METHODS: In order to study the changes of PLC during the 30 years, the clinical data of 3250 patients with PLC from 10 medical institutions of China were collected, ana- lyzed , and compared with those of 3254 PLC patients be- fore the 30 years. RESULTS: In the 3250 patients aged 1-80 years, with an average age of 49.1 years, the male to female ratio (2.3:1) was lower than that before the 30 years. 73.5% of the 3250 patients sought medical advice within 3 months after the onset of the disease in contrast to 63.8% before the 30 years. Compared with those patients before the 30 years the symptoms and signs were alleviated generally. The HBsAg positive rate was 81.0%, but the HCV-Ab positive rate was 13.2%. The AFP level in 75% of patients was elevated, but in the remaining 25% was normal. 1912 patients (58.8%) were confirmed pathologically. Among them 1755 patients (91.8%) had hepatocellular carcinoma. The overall resec- tion rate was 46.3%. Those who had early, middle, late stage carcinoma accounted for 29.9%, 51.5%, and 18.6%respectively in contrast to 0.4%, 47.0%, and 52.6% repor- ted before the 30 years. The 1-, 3-, 5-year survival rates of the patients were 66.1%, 39.7%, and 32.5% respectively, whereas 93.5%, 70.1%, and 59.1% for the early stage pa- tients, and 65.3%, 30.5%, and 23.5% for the middle stage patients. The half and 1-year survival rates of the late stage patients were 52.5%, and 14.7%, respectively. CONCLUSION: Comparison with the clinical data before and after the 30 years show that PLC can be diagnosed ear- ly. More PLC patients tend to undergo resection while re- ceiving a better conservative treatment, which ensures a prognosis.Bing-Hui Yang, Jing-Lin Xia, Li-Wen Huang, Zhao-You Tang, Ming-Shan Chen, Jin-Qing Li, An-Min Liang, Qin-Guo Mo, Hui-Shan Lu, Chao-Liu Dai, Lu-Nan Yan, Zhi-Jian Yu, Rong-Sheng Rao, Le-Qun Li, Zhi-Xiong Su, Zhuang-Wei Fang Shanghai, China Liver Cancer Institute & Zhongshan Hospital, Fudan University, Shanghai 200032, China Tumor Hospital, Zhongshan University, Guangzhou 510000, China Tumor Hospital, Guangxi Medical Universi- ty, Nanning 530000, China Xiehe Hospital, Fujian Medical University, Fuzhou 350000, China Second Hos- pital, Chinese Medical University, Shenyang 110000, China Huaxi Hospital, Sichuan University, Chengdu 610041, China Hospital Affiliated to Nantong Medical University, Nantong 226000 , China Second Hospital, Jiangxi Medical University, Nanchang 330000 , China First Hospital Affiliated to Guangxi Medical University, Nanning 530000 , China People’s Hospital of Hainan Province, Haikou 570000, China 2004Hepatobiliary & Pancreatic Diseases International2004,3,2:20
4Thyroid Nodules in Type 2 Diabetes Mellitus显示文摘The present analysis aims to investigate the prevalence of thyroid nodules in type 2 diabetes mellitus (T2DM) population.We searched PubMed,EMBASE,and Web of Science from inception to the March 1,2018.The studies were selected to estimate the prevalence of thyroid nodules in T2DM subjects and to compare the prevalence of thyroid nodules in different glucose tolerance status.The random effects model was used,and the outcome was presented as a pooled prevalence proportion with 95% confidence interval (95% CI) or a summary odds ratio (OR) with 95% CI.In the end,9 studies met the inclusion criteria and were included in the analysis.The pooled prevalence of thyroid nodules was 60%(95% CI:0.52,0.68) for T2DM 2 diabetes patients,50%(95% CI:0.4& 0.51) for pre-diabetes,and 43%(95% CI:0.34,0.52) for normal glucose tolerance population.Compared with patients without diabetes,diabetes subjects are more likely to develop thyroid nodules,adjusted OR for thyroid nodule was 1.78 (95% CI:1.25,2.55).Insulin resistance might be involved in thyroid nodule development.Hong-mei ZHANG Qi-wen FENG Yi-xin NIU Qing SU Xia WANG 2019Current Medical Science2019,39,4:19
5Immunogenicity noninferiority study of 2 doses and 3 doses of an Escherichia coli-produced HPV bivalent vaccine in girls vs.3 doses in young women显示文摘A new HPV-16/18 bivalent vaccine expressed by the Escherichia coli has been proven to be efficacious in adult women.A randomized,immunogenicity noninferiority study of this candidate vaccine was conducted in December 2015 in China.Girls aged 9–14 years were randomized to receive 2 doses at months 0 and 6(n=301)or 3 doses at months 0,1 and 6(n=304).Girls aged 15–17 years(n=149)and women aged 18–26 years(n=225)received 3 doses.The objectives included noninferiority analysis of the IgG geometric mean concentration(GMC)ratio(95%CI,lower bound>0.5)to HPV-16 and HPV-18 at month 7 in girls compared with women.In the per-protocol set,the GMC ratio of IgG was noninferior for girls aged 9–17 years receiving 3 doses compared with women(1.76(95%CI,1.56,1.99)for HPV-16 and 1.93(95%CI,1.69,2.21)for HPV-18)and noninferior for girls aged 9–14 years receiving 2 doses compared with women(1.45(95%CI,1.25,1.62)for HPV-16 and 1.17(95%CI,1.02,1.33)for HPV-18).Noninferiority was also demonstrated for neutralizing antibodies.The immunogenicity of the HPV vaccine in girls receiving 3 or 2 doses was noninferior compared with that in young adult women.Yue-Mei Hu Meng Guo Chang-Gui Li Kai Chu Wen-Gang He Jing Zhang Jian-Xiang Gu Juan Li Hui Zhao Xiang-Hong Wu Bi-Zhen Lin Zhi-Jie Lin Xing-Mei Yao Ya-Fei Li Fei-Xue Wei Yue Huang Ying-Ying Su Feng-Cai Zhu Shou-Jie Huang Hui-Rong Pan Ting Wu Jun Zhang Ning-Shao Xia 2020Science China(Life Sciences)2020,63,4:19
6Formation mechanisms of megadunes and lakes in the Badain Jaran Desert,Inner Mongolia显示文摘Field observations demonstrate that calc-sinters occurred in the lakes of Badain Jaran Desert. 87Sr/86Sr ratios,14C,δ 13C and mineral com-positions of calc-sinters,and 3He/4He,4He/20Ne,δ 18O,δ D,pH and TDS of water from springs and lakes are analyzed in detail. The results indicate that the lake water is supplied through deep fault zone. The “ker-nel” of stabilized dunes in the Badain Jaran Desert perhaps consists of calc-sinters and calcareous ce-mentation layers. Deep-seated groundwater effuses from this “kernel” and recharges to lakes in desert. Precipitation and snowmelt water from the Qing-hai-Tibet Plateau is fed into the Badain Jaran Desert,Gurinai,Wentougaole and Ejinqi areas through the Xigaze-Langshan Fault zone. The isotopic composi-tions of groundwater in the Alax Plateau are abnor-mal due to the strong evaporation of the Gyaring and Ngoring lake water in the headstream of the Yellow River. Groundwater dissolves dissoluble fractions of rocks during its transportation through the fault zone and flows out of the mouth of spring in the Badan Jaran Desert. The dissoluble fractions are finally de-veloped into calc-sinters and calcareous cementation layers around the spring. Calci-sinters are gradually largened and eventually emerge on the surface of lake water. Eolian sands accumulate on the surfaces of calc-sinters and calcareous cementation layers,and eventually develop into dunes. Invasion of magma causes an increase in the temperature of groundwater within the faults. Groundwater evapora-tion provides water vapor for the formation of humid stabilized dunes during its upwelling. Rhizoconcre-tions found in Yihejigede indicate that the dune was formed and remained immovable 4700 years ago. The height of the megadunes is proportional to thermal quantity carried by the groundwater.CHEN Jiansheng ZHAO Xia SHENG Xuefen DONG Haizhou RAO Wenbo SU Zhiguo 2006Chinese Science Bulletin2006,51,24:19
7Analysis and Numerical Simulation of Rolling Contact between Sphere and Cone显示文摘In non-conforming rolling contact, the contact stress is highly concentrated in the contact area. However, there are some limitations of the special contact model and stress model used for the theoretical study of the phenomenon, and this has prevented in-depth analysis of the associated friction, wear, and failure. This paper is particularly aimed at investigating the area of rolling contact between a sphere and a cone, for which purpose the boundary is determined by the Hertz theory and the geometries of the non-conforming surfaces. The phenomenon of stick-slip contact is observed to occur in the contact area under the condition of no-full-slip(Q < μ·P). Using the two-dimensional rolling contact theory developed by CARTER, the relative positions of the stick and slip regions and the distribution of the tangential force over the contact area are analyzed. Furthermore, each stress component is calculated based on the Mc Ewen theory and the idea of narrow band. The stress equations for the three-dimensional rolling contact between the sphere and the cone are obtained by the principle of superposition, and are used to perform some numerical simulations. The results show that the stress components have a large gradient along the boundary between the stick and slip regions, and that the maximum stress is inversely proportional to the contact coefficient and proportional to the friction coefficient. A new method for investigating the stress during non-classical three-dimensional rolling contact is proposed as a theoretical foundation for the analysis of the associated friction, wear, and failure.ZHAO Yanling XIA Chengtao WANG Hongbo XUAN Jiaping XIANG Jingzhong LIU Xianli SU Xiangguo 2015Chinese Journal of Mechanical Engineering2015,28,3:18
8Synergistic effect of fluorination on both donor and acceptor materials for high performance non-fullerene polymer solar cells with 13.5% efficiency显示文摘A high performance polymer solar cells(PSCs) based on polymer donor PM6 containing fluorinated thienyl benzodithiophene unit and n-type organic semiconductor acceptor IT-4 F containing fluorinated end-groups were developed. In addition to complementary absorption spectra(300–830 nm) with IT-4 F, the PM6 also has a deep HOMO(the highest occupied molecular) level(-5.50 e V), which will lower the open-circuit voltage(V_(oc)) sacrifice and reduce the E_(loss) of the IT-4 F-based PSCs. Moreover, the strong crystallinity of PM6 is beneficial to form favorable blend morphology and hence to suppress recombination. As a result, in comparison with the PSCs based on a non-fluorinated D/A pair of PBDB-T:ITIC with a medium PCE of 11.2%, the PM6:IT-4 Fbased PSCs yielded an impressive PCE of 13.5% due to the synergistic effect of fluorination on both donor and acceptor, which is among the highest values recorded in the literatures for PSCs to date. Furthermore, a PCE of 12.2% was remained with the active layer thickness of up to 285 nm and a high PCE of 11.4% was also obtained with a large device area of 1 cm^2. In addition, the devices also showed good storage, thermal and illumination stabilities with respect to the efficiency. These results indicate that fluorination is an effective strategy to improve the photovoltaic performance of materials, as well as the both fluorinated donor and acceptor pair-PM6:IT-4 F is an ideal candidate for the large scale roll-to-roll production of efficient PSCs in the future.Qunping Fan Wenyan Su Yan Wang Bing Guo Yufeng Jiang Xia Guo Feng Liu Thomas P.Russell Maojie Zhang Yongfang Li 2018Science China Chemistry2018,61,5:18
9Clinical application and mechanism of traditional Chinese medicine in treatment of lung cancer显示文摘Lung cancer is a malignant tumor characterized by a rapid proliferation rate,less survivability,high mortality,and metastatic potential.This review focuses on updated research about the clinical application of traditional Chinese medicine(TCM)as an adjuvant therapy to lung cancer treatment and the mechanisms of TCM effect on lung cancer in vitro and in vivo.We summarized the recent 5 years of different research progress on clinical applications and antitumor mechanisms of TCM in the treatment of lung cancer.As a potent adjuvant therapy,TCM could enhance conventional treatments(chemotherapy,radiation therapy,and epidermal growth factor receptors[EGFRs]tyrosine kinase inhibitors[TKIs])effects as well as provide synergistic effects,enhance chemotherapy drugs chemosensitivity,reverse drug resistance,reduce adverse reactions and toxicity,relieve patients’pain and improve quality of life(QOL).After treating with TCM,lung cancer cells will induce apoptosis and/or autophagy,suppress metastasis,impact immune reaction,and therapeutic effect of EGFR-TKIs.Therefore,TCM is a promisingly potent adjuvant therapy in the treatment of lung cancer and its multiple mechanisms are worthy of an in-depth study.Xiao-Lin Su Jiang-Wei Wang Hui Che Chang-Fu Wang Hai Jiang Xia Lei Wan Zhao Hai-Xue Kuang Qiu-Hong Wang 2020Chinese Medical Journal2020,,24:16
10Prevalence, awareness, treatment, and control of hypertension in the non-dialysis chronic kidney disease patients显示文摘ZHENG Ying CAI Guang-yan CHEN Xiang-mei FU Ping CHEN Jiang-hua DING Xiao-qiang YU Xue-qing LIN Hong-li LIU Jian XIE Ru-juan WANG Li-ning NI Zhao-hui LIU Fu-you YIN Ai-ping XING Chang-ying WANG Li SHI Wei LIU Jian-she HE Ya-ni DING Guo-hua LI Wen-ge WU Guang-li MIAO Li-ning CHEN Nan SU Zhen MEI Chang-lin ZHAO Jiu-yang GU Yong BAI Yun-kai LUO Hui-min LIN Shan CHEN Meng-hua GONG Li YANG Yi-bin YANG Xiao-ping LI Ying WAN Jian-xin WANG Nian-song LI Hai-ying XI Chun-sheng HAO Li XU Yan FANG Jing-ai LIU Bi-cheng LI Rong-shan WANG Rong ZHANG Jing-hong WANG Jian-qin LOU Tan-qi SHAO Feng-min MEI Feng LIU Zhi-hong YUAN Wei-jie SUN Shi-ren ZHANG Ling ZHOU Chun-hua CHEN Qin-kai JIA Shun-lian GONG Zhi-feng GUAN Guang-ju XIA Tian ZHONG Liang-bao 2013Chinese Medical Journal2013,,12:16
11Interventional mechanisms of herbs or herbal extracts on renal interstitial fibrosis显示文摘Renal interstitial fibrosis(RIF) is a common development in chronic renal diseases that can lead to uremia and be life-threatening. The RIF pathology has complicated extracellular and intercellular mechanisms, involving many cells and cytokines, resulting in an incomplete mechanistic understanding of the disease. Finding effective herbs or herbal extracts for prevention and treatment of RIF is crucial because current medical approaches do not reliably slow or reverse RIF. In recent years, many experts have worked to identify herbs or herbal extracts to combat RIF both in vivo and in vitro, with some success. This review attempts to summarize the possible interventional mechanisms of herbs or herbal extracts involved in protecting and reversing RIF. The authors found some herbs and their extracts that may ameliorate renal impairments through anti-inflammation, anti-fibrogenesis and stabilization of extra cellular matrix. Among them, tetramethylpyrazine/ligustrazine, curcumin and polyglucoside of Tripterygium have experimentally shown good potential for improving RIF. However, conclusive evidence is still needed, especially in randomized controlled clinical trials. We expect that herbs or herbal extracts will play an important role in RIF treatment and reversal in the future.Jia Xia Li-qun He Xiao Su 2016Journal of Integrative Medicine2016,14,3:16
12Distinctive melt activity and chromite mineralization in Luobusa and Purang ophiolites, southern Tibet: constraints from trace element compositions of chromite and olivine显示文摘To investigate the factors controlling the mineralization in ophiolites we systematically compared the petrology and mineral compositions of the harzburgites/lherzolites, dunites and chromitites in the Luobusa and Purang ophiolites. Generally, the petrological features and trace element compositions of chromite and olivine in peridotite and chromitite are distinctly different between the two ophiolites.In Luobusa, boninitic melts are inferred to have interacted with the harzburgites and modified the distributions of some trace elements(e.g., Ni, Mn and V) in chromite and olivine. The subsequently formed dunites and chromitites experienced significant elemental exchange. In contrast, the Purang ophiolite contains a wider range of chromitite compositions and records diverse melt activities, such as the growth of relatively abundant secondary clinopyroxene. The metasomatic melts were enriched in Al and depleted in Si, Na and highly incompatible trace elements(e.g., Nb, Zr). Such melts resemble MORBlike melts proposed in the literature but are assumed to be more hydrous than typical MORB because of presence of hydrous minerals. The parental magmas of the Purang dunites and intermediate chromitites are inferred to be compositionally intermediate between boninitic and MORB-like melts. In addition,the more refractory nature of the Luobusa harzburgites facilitated a high Cr concentration gradient with the interacting melts, making it easier to increase Cr in the melts. Crystallization of clinopyroxene and amphibole in the Purang ophiolite accommodated significant amounts of Cr and water, respectively,and negatively affected Cr concentration and chromite crystallization. The concentration of chromite to form chromitites requires the presence of focused melt channels.Benxun Su Meifu Zhou Jiejun Jing Paul T.

13Baicalein ameliorates ulcerative colitis by improving intestinal epithelial barrier via AhR/IL-22 pathway in ILC3s显示文摘Ulcerative colitis(UC)is a chronic inflammatory disease of the gastrointestinal tract,which is closely related to gut barrier dysfunction.Emerging evidence shows that interleukin-22(IL-22)derived from group 3 innate lymphoid cells(ILC3s)confers benefits on intestinal barrier,and IL-22 expression is controlled by aryl hydrocarbon receptor(AhR).Previous studies show that baicalein protects the colon from inflammatory damage.In this study we elucidated the molecular mechanisms underlying the protective effect of baicalein on intestinal barrier function in colitis mice.Mice were administered baicalein(10,20,40 mg·kg^(-1)·d^(-1),i.g.)for 10 days;the mice freely drank 3%dextran sulfate sodium(DSS)on D1-D7 to induce colitis.We showed that baicalein administration simultaneously ameliorated gut inflammation,decreased intestinal permeability,restored tight junctions of colons possibly via promoting AhR/IL-22 pathway.Co-administration of AhR antagonist CH223191(10 mg/kg,i.p.)partially blocked the therapeutic effects of baicalein in colitis mice,whereas AhR agonist FICZ(1μg,i.p.)ameliorated symptoms and gut barrier function in colitis mice.In a murine lymphocyte line MNK-3,baicalein(5-20μM)dose-dependently increased the expression of AhR downstream target protein CYP1A1,and enhanced IL-22 production through facilitating AhR nuclear translocation,these effects were greatly diminished in shAhR-MNK3 cells,suggesting that baicalein induced IL-22 production in AhR-dependent manner.To further clarify that,we constructed an in vitro system consisting of MNK-3 and Caco-2 cells,in which MNK-3 cell supernatant treated with baicalein could decrease FITC-dextran permeability and promoted the expression of tight junction proteins ZO-1 and occluding in Caco-2 cells.In conclusion,this study demonstrates that baicalein ameliorates colitis by improving intestinal epithelial barrier via AhR/IL-22 pathway in ILC3s,thus providing a potential therapy for UC.Yan-yang Li Xiao-jing Wang Yu-lin Su Qing Wang Shao-wei Huang Zeng-feng Pan Yan-ping Chen Jun-jie Liang Mei-ling Zhang Xue-qian Xie Zhi-yun Wu Jin-yan Chen Lian Zhou Xia Luo 2022Acta Pharmacologica Sinica2022,43,6:14
14Gas Sources of Natural Gas Hydrates in the Shenhu Drilling Area, South China Sea: Geochemical Evidence and Geological Analysis显示文摘The Shenhu gas hydrate drilling area is located in the central Baiyun sag, Zhu Ⅱ depression, Pearl River Mouth basin, northern South China Sea. The gas compositions contained in the hydrate-bearing zones is dominated by methane with content up to 99.89% and 99.91%. The carbon isotope of the methane (δ13C1 ) are 56.7‰ and 60.9‰, and its hydrogen isotope (δD) are 199‰ and 180‰, respectively, indicating the methane from the microbial reduction of CO2 . Based on the data of measured seafloor temperature and geothermal gradient, the gas formed hydrate reservoirs are from depths 24-1699 m below the seafloor, and main gas-generation zone is present at the depth interval of 416-1165 m. Gas-bearing zones include the Hanjiang Formation, Yuehai Formation, Wanshan Formation and Quaternary sediments. We infer that the microbial gas migrated laterally or vertically along faults (especially interlayer faults), slump structures, small-scale diapiric structures, regional sand beds and sedimentary boundaries to the hydrate stability zone, and formed natural gas hydrates in the upper Yuehai Formation and lower Wanshan Formation, probably with contribution of a little thermogenic gas from the deep sedments during this process.ZHU Youhai HUANG Xia FU Shaoying SU Pibo 2013Acta Geologica Sinica(English Edition)2013,87,3:13
15Research progress of heat stroke during 1989–2019: A bibliometric analysis显示文摘Background: Heat stroke(HS) is an acute physical disorder that is associated with a high risk of organ dysfunction and even death. HS patients are usually treated symptomatically and conservatively;however, there remains a lack of specific and effective drugs in clinical practice. An analysis of publication contributions from institutions, journals and authors in different countries/regions was used to study research progress and trends regarding HS.Methods: We extracted all relevant publications on HS between 1989 and 2019 from Web of Science. Using the Statistical Package for Social Science(SPSS, version 24) and the software GraphPad Prism 8, graphs were generated and statistical analyses were performed, while VOSviewer software was employed to visualize the research trends in HS from the perspectives of co-occurring keywords.Results: As of April 14, 2020, we identified 1443 publications with a citation frequency of 5216. The United States accounted for the largest number of publications(36.2%) and the highest number of citations(14,410), as well as the highest H-index at 74. Although the sum of publications from China ranked second, there was a contradiction between the quantity and quality of publications. Furthermore, Medicine & Science in Sports & Exercise published the most papers related to HS, with Lin MT publishing the most papers in this field(112), while the review by Knochel JP received the highest citation frequency at 969. The keyword heat-stress appeared most recently, with an average appearing year of 2015.5. In the clinical research cluster, exertional heat-stroke was determined to be the hotspot, while ambient-temperature and heat waves were the new trends in the epidemiological research cluster.Conclusions: Corresponding to this important field, while the contributions of the publications from the United States were significant, the mismatch between the quantity and quality of publications from China must be examined. Moreover, it is hypothesized that clinical and epidemiological studies may become hotspots in the near future.De-Meng Xia Xu-Ren Wang Pan-Yu Zhou Tian-Le Ou Lei Su Shuo-Gui Xu 2021Military Medical Research2021,8,3:12
16Satellite UV-Vis spectroscopy:implications for air quality trends and their driving forces in China during 2005-2017显示文摘Abundances of a range of air pollutants can be inferred from satellite UV-Vis spectroscopy measurements by using the unique absorption signatures of gas species.Here,we implemented several spectral fitting methods to retrieve tropospheric NO_(2),SO_(2),and HCHO from the ozone monitoring instrument(OMI),with radiative simulations providing necessary information on the interactions of scattered solar light within the atmosphere.We analyzed the spatial distribution and temporal trends of satellite-observed air pollutants over eastern China during 2005-2017,especially in heavily polluted regions.We found significant decreasing trends in NO_(2) and SO_(2) since 2011 over most regions,despite varying temporal features and turning points.In contrast,an overall increasing trend was identified for tropospheric HCHO over these regions in recent years.Furthermore,generalized additive models were implemented to understand the driving forces of air quality trends in China and assess the effectiveness of emission controls.Our results indicated that although meteorological parameters,such as wind,water vapor,solar radiation and temperature,mainly dominated the day-to-day and seasonal fluctuations in air pollutants,anthropogenic emissions played a unique role in the long-term variation in the ambient concentrations of NO_(2),SO_(2),and HCHO in the past 13 years.Generally,recent declines in NO_(2) and SO_(2) could be attributed to emission reductions due to effective air quality policies,and the opposite trends in HCHO may urge the need to control anthropogenic volatile organic compound(VOC)emissions.Chengxin Zhang Cheng Liu Qihou Hu Zhaonan Cai Wenjing Su Congzi Xia Yizhi Zhu Siwen Wang Jianguo Liu 2019Light(Science & Applications)2019,8,1:11
17Casticin induces caspase-mediated apoptosis via activation of mitochondrial pathway and upregulation of DR5 in human lung cancer cells显示文摘Objective:To assess if casticin induces caspase-mediated apoptosis via activation of mitochondrial pathway and upregulation of DR5 in human lung cancer ceils.Methods:Human non-small-cell lung carcinoma cell lines H460,AS49 and H157 were cultured in vitro.The cytotoxic activities were determined using MTT assay.The apoptotic cells death was examined by flow cytometry using PI staining and DMA agarose gel electrophoresis.The activities of caspase-3, -8 and -9 were measured via ELISA.Cellular fractionation was determined by flow cytometry to assess release of cytochrome c and the mitochondrial transmembrane potential.Bcl-2/Bcl-XL/ XIAP/Bid/ DR5 and DR4 proteins were analyzed using western blot.Results:The concentrations required for a 50%decrease in cell growth(IC50) ranged from 1.8 to 3.2 Jt M.Casticin induced rapid apoptosis and triggered a series of effects associated with apoptosis by way of mitochondrial pathway,including the depolarization of the mitochondrial membrane,release of cytochrome c from mitochondria,activation of procaspase-9 and -3,and increase of DNA fragments.Moreover, the pan caspase inhibitor zVAD-FMK and the caspase-3 inhibitor zOEVD-FMK suppressed casticin-induced apoptosis.In addition,casticin induced XIAP and Bcl-XL down-regulation, Bax upregulation and Bid clearage.In H157 cell line,casticin increased expression of DRS at protein levels but not affect the expression of DR4.The prelreatmenl with DR5/Fc chimera protein effectively attenuated casticin-induced apoptosis in H157 cells.No correlation was found between cell sensitivity to casticin and that to p53 status,suggesting that casticin induce a p53- independent apoptosis.Conclusions:Our results demonstrate that casticin induces caspase-mediated apoptosis via activation of mitochondrial pathway and upregulation of DRS in human lung cancer cells.Yuan Zhou Yi Peng Qi-Qi Mao Xia Li Ming-Wu Chen Ting Su Li Tian Nai-Quan Mao Ling-Zhi Long Mei-Fang Quan Fei Liu Su-Fang Zhou Yong-Xiang Zhao 2013Asian Pacific Journal of Tropical Medicine2013,6,5:11

20The Development of A Fluorescence Polarization Immunoassay for Aflatoxin Detection显示文摘A fluorescence polarization immunoassay(FPIA)was developed for the analysis ofaflatoxins(AFs)using an anti-aflatoxin B1(AFB1)monoclonal antibody and a novel fluorescein-labeled AFB1tracer.The FPIA showed an IC50 value of 23.33ng/mL with a limit of detection of 13.12 ng/mL for AFB1.The cross-reactivities of AFB1,AFB2,AFG1,AFG2,AFM1,and AFM2 with the antibody were100%,65.7%,143%,23.5%,111.4%,and 2%,respectively.The group-specificity of anti-AFB1mAb indicated that the FPIA could potentially be used in a screening method for the detection of total AFs,albeit not AFG2 and AFM2.The total time required for analyzing 96 samples in one microplate was less than 5 min.This study demonstrates the potential usefulness of the FPIA as a rapid and simple technique for monitoring AFs.SHENG Ya Jie EREMIN Sergei MI Tie Jun ZHANG Su Xia SHEN Jian Zhong WANG Zhan Hui 2014Biomedical and Environmental Sciences2014,27,2:10
