1Improved ant colony optimization algorithm for the traveling salesman problems显示文摘Ant colony optimization(ACO) is a new heuristic algorithm which has been proven a successful technique and applied to a number of combinatorial optimization problems.The traveling salesman problem(TSP) is among the most important combinatorial problems.An ACO algorithm based on scout characteristic is proposed for solving the stagnation behavior and premature convergence problem of the basic ACO algorithm on TSP.The main idea is to partition artificial ants into two groups:scout ants and common ants.The common ants work according to the search manner of basic ant colony algorithm,but scout ants have some differences from common ants,they calculate each route's mutation probability of the current optimal solution using path evaluation model and search around the optimal solution according to the mutation probability.Simulation on TSP shows that the improved algorithm has high efficiency and robustness.Rongwei Gan Qingshun Guo Huiyou Chang Yang Yi 2010Journal of Systems Engineering and Electronics2010,21,2:22
2miR-374b-5p suppresses RECK expression and promotes gastric cancer cell invasion and metastasis显示文摘AIM:To profile expression of micro RNAs(mi RNAs)in gastric cancer cells and investigate the effect of mi R-374b-5p on gastric cancer cell invasion and metastasis.METHODS:An mi RNA microarray assay was performed to identify mi RNAs differentially expressed in gastric cancer cell lines(MGC-803 and SGC-7901)compared with a normal gastric epithelial cell line.Upregulation of mi R-374b-5p was newly identified and confirmed via quantitative real-time reverse transcriptionPCR(q RT-PCR).MGC-803 cells were transfected with a synthesized anti-mi R-374b-5p sequence or a control vector using Lipofectamine reagent,or treated with transfection reagent alone or phosphate-buffered saline as controls.Rate of transfection was verified after 48 h by q RT-PCR.Cells were then subjected to transwell migration,wound scratch and cell counting kit-8 assays.A bioinformatic analysis to identify mi R-374b-5p target genes was performed using mi Randa,Pic Tar and Target Scan software.A dual luciferase reporter assay was performed to evaluate the influence of mi R-374b-5p on target gene activation,and q RT-PCR and Western blot were used to evaluate the levels of target m RNA and protein following transfection with mi R-374b-5p antisense oligonucleotides.RESULTS:The microarray profiling revealed downregulation of 14(fold change<0.667;P<0.05)and upregulation of 12(fold change>1.50;P<0.05)mi RNAs in MGC-803 and SGC-7901 cells compared with GES-1 controls.The upregulation of mi R-374b-5p(fold change=1.75 and 1.64 in MGC-803 and SGC-7901,respectively;P<0.05)was confirmed by q RT-PCR.Compared with the control groups,the restoration of mi R-374b-5p expression with anti-mi R-374b-5p significantly suppressed the metastasis,invasion and proliferation of MGC-803 cells.The bioinformatic analysis predicted that the 3’untranslated region(UTR)of reversion-inducing cysteine-rich protein with Kazal motif(RECK)contains three mi R-374b-5p target sequences.RECK was verified as a target gene in a dual luciferase reporter assay showing that activation of RECK 3’UTR-pmir GLO was increased by co-transfection with mi R-374b-5p.Finally,transfection of mi R-374b-5p antisense oligonucleotides increased m RNA and protein levels of RECK in MGC-803cells(P<0.05).CONCLUSION:These findings indicate that upregulation of mi R-374b-5p contributes to gastric cancer cell metastasis and invasion through inhibition of RECK expression.Juan Xie Zhi-Hui Tan Xia Tang Ming-Shu Mo Yan-Ping Liu Run-Liang Gan Yi Li Li Zhang Guo-Qing Li 2014World Journal of Gastroenterology2014,20,46:15
3Changing Proportions of HIV-1 Subtypes and Transmitted Drug Resistance Among Newly Diagnosed HIV/AIDS Individuals—China,2015 and 2018显示文摘Introduction:With the expansion of human immunodeficiency virus(HIV)antiretroviral therapy(ART),HIV drug resistance is becoming more and more serious.This study describes the changing prevalence of HIV-1 subtypes and transmitted drug resistance(TDR)among newly diagnosed individuals in China,2015 and 2018.Methods:A total of 8,980 individuals in 2015 and 2018 from 31 provincial-level administrative divisions(PLADs)were enrolled in this study.Viral RNAs were amplified and sequenced using an in-house polymerase chain reaction(PCR)protocol.The Stanford HIV Drug Resistance Database(HIVdb)was used to predict susceptibility to 12 antiretroviral drugs.Results:The prevalence of TDR was not significantly increased over time.The prevalence of TDR was 3.8%and 4.4%in 2015 and 2018,respectively(P=0.13).The prevalence of CRF55_01B increased from 2.3%in 2015 to 3.9%in 2018(P<0.001).The drug resistance prevalence of nonnucleoside reverse transcriptase inhibitors(NNRTI)increased from 2.4%in 2015 to 3.3%in 2018(P<0.01).The prevalence of E138(P<0.001),H221(P=0.03),and V179(P<0.001)mutations increased from 0.30%,0.09%,and 0.70%in 2015 to 1.10%,0.30%,and 1.70%in 2018,respectively.Conclusions:HIV drug resistance affects the effect of antiretroviral treatment,so the monitoring of HIV TDR should be strengthened to control the transmission of HIV drug resistance.Jingjing Hao Shan Zheng Mengze Gan Aobo Dong Ruihua Kang Miaomiao Li Shuai Zhao Jing Hu Chang Song Lingjie Liao Yi Feng Yiming Shao Yuhua Ruan Hui Xing 2021China CDC weekly2021,3,53:13

7Simulated Microgravity Conditions and Carbon Ion Irradiation Induce Spermatogenic Cell Apoptosis and Sperm DNA Damage显示文摘Objective To investigate the effect of simulated microgravity and carbon ion irradiation(CIR) on spermatogenic cell apoptosis and sperm DNA damage to the testis of male Swiss Webster mice,and assess the risk associated with space environment.Methods Sperm DNA damage indicated by DNA fragmentation index(DFI) and high DNA stainability(HDS) was measured by sperm chromatin structure assay(SCSA).Apoptosis of spermatogenic cells was detected by annexin V-propidium iodide assay.Bax(the expression levels of p53) and proliferating cell nuclear antigen(PCNA) were measured by immunoblotting;p53 and PCNA were located by immunohistology.Results HDS,DFI,apoptosis index,and the expression levels of p53 and Bax were detected to be significantly higher in the experimental groups(P<0.05) compared with those in the control group;however,the PCNA expression varied to a certain degree.p53-and PCNA-positive expression were detected in each group,mainly in relation to the spermatogonic cells and spermatocytes.Conclusion The findings of the present study demonstrated that simulated microgravity and CIR can induce spermatogenic cell apoptosis and sperm DNA damage.Sperm DNA damage may be one of the underlying mechanisms behind male fertility decline under space environment.These findings may provide a scientific basis for protecting astronauts and space traveler's health and safety.LI Hong Yan ZHANG Hong MIAO Guo Ying XIE Yi SUN Chao DI Cui Xia LIU Yang LIU Yuan Yuan ZHANG Xin MA Xiao Fei XU Shuai GAN Lu ZHOU Xin 2013Biomedical and Environmental Sciences2013,26,9:10
8Comparison of sentinel lymph node detection performances using blue dye in conjunction with indocyanine green or radioisotope in breast cancer patients: a prospective singlecenter randomized study显示文摘Objective:This randomized study aimed to compare the clinical efficacy between the novel dual tracer composed of indocyanine green(ICG)and blue dye(BD)and the conventional dual tracer composed of radioisotope and BD for sentinel lymph node(SLN)mapping in patients with breast cancer.Methods:This study enrolled 471 clinically lymph node-negative patients with primary breast cancer.All patients underwent mastectomy,and those undergoing sentinel lymph node biopsy(SLNB)were randomized to receive blue dye plus radioisotope(RB group)or BD plus ICG(IB group).The detection performances on SLN identification rate,positive SLN counts,detection sensitivity,and false-negative rate were compared between the two groups.Results:In the IB group,97%(194/200)of the patients who underwent the ICG and BD dual tracer injection showed fluorescentpositive lymphatic vessels within 2–5 min.The identification rate of SLNs was comparable between the IB group(99.0%,198/200)and the RB group(99.6%,270/271)(P=0.79).No significant differences were observed in the identification rate of metastatic SLNs(22.5%vs.22.9%,P>0.05,RB group vs.IB group,the same below),positive SLN counts(3.72±2.28 vs.3.91±2.13,P>0.05),positive metastatic SLN counts(0.38±0.84 vs.0.34±0.78,P>0.05),SLNB detection sensitivity(94.4%vs.92.5%,P>0.05),or false-negative rate(5.6%vs.7.5%,P>0.05)between the two groups.Conclusions:ICG can be used as a promising alternative tracer for radioisotope in SLN mapping,and when it is combined with BD in lymphangiography,it offers comparable detection sensitivity compared to the conventional lymphatic mapping strategies that are widely used in clinical practice.Long Yuan Xiaowei Qi Yi Zhang Xinhua Yang Fan Zhang Linjun Fan Li Chen Kongyong Zhang Ling Zhong Yanling Li Sijie Gan Wenying Fu Jun Jiang 2018Cancer Biology & Medicine2018,15,4:9
9Embedding based quantile regression neural network for probabilistic load forecasting显示文摘Compared to traditional point load forecasting,probabilistic load forecasting(PLF) has great significance in advanced system scheduling and planning with higher reliability. Medium term probabilistic load forecasting with a resolution to an hour has turned out to be practical especially in medium term energy trading and can enhance the performance of forecasting compared to those only utilizing daily information. Two main uncertainties exist when PLF is implemented: the first is the temperature fluctuation at the same time of each year; the second is the load variation which means that even if observed indicators are fixed since other observed external indicators can be responsible for the variation. Therefore, we propose a hybrid model considering both temperature uncertainty and load variation to generate medium term probabilistic forecasting with hourly resolution. An innovative quantile regression neural network with parameter embedding is established to capture the load variation, and a temperature scenario based technique is utilized to generate temperatureforecasting in a probabilistic manner. It turns out that the proposed method overrides commonly used benchmark models in the case study.Dahua GAN Yi WANG Shuo YANG Chongqing KANG 2018Journal of Modern Power Systems and Clean Energy2018,6,2:9

11THF_1 mutations lead to increased basal and wound-induced levels of oxylipins that stimulate anthocyanin biosynthesis via COI_1 signaling in Arabidopsis显示文摘Mutants defective in chloroplast development or photosynthesis are liable to accumulate higher levels of anthocyanin in photo-oxidative stress.However,regulatory mechanisms of anthocyanin biosynthesis in the mutants remain unclear.Here,we investigated the mechanism by which the deletion of thylakoid formation1(THF1) leads to an increased level of anthocyanin in Arabidopsis thaliana L.Physiological and genetic evidence showed that the increased level of anthocyanin in thf1 is dependent on coronatine-insensitive1(COM)signaling.Our data showed that thf1 had higher levels of basalα-linolenic acid(α-LeA),and methyl jasmonate(JA)-induced α-LeA and 12-oxophytodienoic acid(OPDA) than the wild type(WT).Consistently,expression levels of phospholipase genes including pPLAIIα and PLA-Iγ1 were elevated in thf1.Furthermore,inhibition of lipase activity by bromoenol lactone,a specific inhibitor of plant pPLA,led to producing identical levels of anthocyanins in WT and thf1 plants.Interestingly,OPDA biosynthesis was triggered by light illumination in isolated chloroplasts,indicating that new protein import into chloroplasts is not required for OPDA biosynthesis.Thus,we conclude that the elevated anthocyanin accumulation in thf1 is attributed to an increase in JA levels.This JA-mediated signaling to coordinate plant metabolism and growth in stress may be conserved in other photosensitive mutants.Yi Gan Hong Li Ye Xie Wenjuan Wu Maoyin Li Xuemin Wang Jirong Huang 2014Journal of Integrative Plant Biology2014,56,9:8

14Host compatibility interacts with seed dispersal to determine smallscale distribution of a mistletoe in Xishuangbanna,Southwest China显示文摘Aims Mistletoe infection between intra- and interspecific hosts can be restricted by seed dispersal, host–mistletoe compatibility and other factors, yet few studies have linked seed dispersal and seedling establishment together for understanding mistletoe plant distribution and demography together in different anthropogenic disturbance forest types at a local scale. The objectives of this study were to examine how three factors—seed disperser behavior, post-dispersal host compatibility and canopy cover—affect the spatial distribution of a generalist mistletoe Dendrophthoe pentandra (Loranthaceae) in plantation and rainforest within Xishuangbanna, Southwest China.MethodsWe observed mistletoe D. pentandra infection patterns at the scale of individual trees and sixteen 400-m2 forest plots in adjacent plantation and rainforest within Xishuangbanna. To elucidate what determines infection patterns at different scales and in different forest types, we observed the behavior of major avian seed dispersers and carried out a seed inoculation experiment to examine how post-dispersal compatibility and light incidence affect the infection of different hosts.Important FindingsDendrophthoe pentandra displayed an aggregated distribution and infected 10 species in our study site, with a significantly higher infection prevalence and intensity in the plantation than in the tropical forest. Different seed dispersers provided contrasting initial mistletoe templates: the specialist frugivore Dicaeum concolor (plain flowerpecker) preferred to fly between mistletoes in infected trees in the plantation and likely intensified existing infections. In contrast, the dietary generalist Pycnonotus jocosus(red-whiskered bulbul) was more likely to visit uninfected trees, thereby establishing new infections. Thus, seed dispersal appears to be an important determinant of the mistletoes distribution, with deposition patterns providing an initial distribution template and determining small-scale patterns. However, post-dispersal and abiotic factors revealed that different host compatibilities and levels of light incidence in different habitats affected the survival of D. pentandra seedlings. Hence, our findings suggest that seed dispersal interacts with host compatibility and canopy cover to determine establishment success, survival and the observed distribution patterns.Yahuang Luo Yi Sui Jianmin Gan Ling Zhang 2016Journal of Plant Ecology2016,9,1:6
15Oxaliplatin and 5-fluorouracil hepatic infusion with lipiodolized chemoembolization in large hepatocellular carcinoma显示文摘AIM: To investigate transarterial chemoembolization(TACE) with hepatic infusion of oxaliplatin and 5-fluorouracil and Lipiodol chemoembolization in large hepatocellular carcinoma(HCC).METHODS: In this retrospective study, 132 patients with unresectable HCCs larger than 10 cm were treated with hepatic infusion of oxaliplatin and 5-fluorouracil followed by Lipiodol chemoembolization. The primary endpoint was overall survival(OS). Sixteen-week disease-control rate, time to progression(TTP), and major complications were also studied. Univariate and multivariate analyses were performed to identify prognostic factors affecting OS and TTP.RESULTS: A total of 319 procedures were performed in the 132 patients. Eleven(8.3%) patients received radical resection following TACE treatment(median time to initial TACE 4.3 ± 2.3 mo). The median OS and TTP were 10.3 and 3.0 mo respectively, with a 50.0% 16-wk disease-control rate. Major complications were encountered in 6.0%(8/132) of patients following TACE and included serious jaundice in 1.5%(2/132) patients, aleukia in 1.5%(2/132), and hepatic failure in 3.0%(4/132). One patient died within one month due to serious hepatic failure and severe sepsis after receiving the second TACE. The risk factor associated with TTP was baseline alpha-fetoprotein level, and vascular invasion was an independent factor related to OS.CONCLUSION: Hepatic infusion of oxaliplatin and 5-fluorouracil followed by lipiodolized-chemoembolization is a safe and promising treatment for patients with HCCs larger than 10 cm in diameter.Jing-Huan Li Xiao-Ying Xie Lan Zhang Fan Le Ning-Ling Ge Li-Xin Li Yu-Hong Gan Yi Chen Ju-Bo Zhang Tong-Chun Xue Rong-Xin Chen Jing-Lin Xia Bo-Heng Zhang Sheng-Long Ye Yan-Hong Wang Zheng-Gang Ren 2015World Journal of Gastroenterology2015,21,13:6
16Establishment and functional characterization of the reversibly immortalized mouse glomerular podocytes(imPODs)显示文摘Glomerular podocytes are highly specialized epithelial cells and play an essential role in establishing the selective permeability of the glomerular filtration barrier of kidney.Maintaining the viability and structural integrity of podocytes is critical to the clinical management of glomerular diseases,which requires a thorough understanding of podocyte cell biology.As mature podocytes lose proliferative capacity,a conditionally SV40 mutant tsA58-immortalized mouse podocyte line(designated as tsPC)was established from the Immortomouse over 20 years ago.However,the utility of the tsPC cells is hampered by the practical inconvenience of culturing these cells.In this study,we establish a user-friendly and reversibly-immortalized mouse podocyte line(designated as imPOD),on the basis of the tsPC cells by stably expressing the wildtype SV40 T-antigen,which is flanked with FRT sites.We show the imPOD cells exhibit long-term high proliferative activity,which can be effectively reversed by FLP recombinase.The imPOD cells express most podocyte-related markers,including WT-1,Nephrin,Tubulin and Vinculin,but not differentiation marker Synaptopodin.The imPOD cells do not form tumor-like masses in vivo.We further demonstrate that TGFb1 induces a podocyte injury-like response in the FLP-reverted imPOD cells by suppressing the expression of slit diaphragm-associated proteins P-Cadherin and ZO-1 and upregulating the expression of mesenchymal markers,a-SMA,Vimentin and Nestin,as well as fibrogenic factors CTGF and Col1a1.Collectively,our results strongly demonstrate that the newly engineered im-POD cells should be a valuable tool to study podocyte biology both under normal and under pathological conditions.Xinyi Yu Liqun Chen Ke Wu Shujuan Yan Ruyi Zhang Chen Zhao Zongyue Zeng Yi Shu Shifeng Huang Jiayan Lei Xiaojuan Ji Chengfu Yuan Linghuan Zhang Yixiao Feng Wei Liu Bo Huang Bo Zhang Wenping Luo Xi Wang Bo Liu Rex C.Haydon Hue H.Luu Tong-Chuan He Hua Gan 2018Genes & Diseases2018,5,2:5
17Climatology of global gravity wave activity and dissipation revealed by SABER/TIMED temperature observations显示文摘Gravity wave activity and dissipation in the height range from the low stratosphere to the low thermosphere(25–115 km)covering latitudes between 50°S and 50°N are statistically studied by using 9-year(January 22,2002–December 31,2010)SABER/TIMED temperature data.We propose a method to extract realistic gravity wave fluctuations from the temperature profiles and treat square temperature fluctuations as GW activity.Overall,the gravity wave activity generally increases with height.Near the equator(0°–10°),the gravity wave activity shows a quasi-biennial variation in the stratosphere(below 40 km)while from 20°to 30°,it exhibits an annual variation below 40 km;in low latitudes(0°–30°)between the upper stratosphere and the low thermosphere(40–115 km),the gravity wave activity shows a semi-annual variation.In middle latitudes(40°–50°),the gravity wave activity has a clear annual variation below 85 km.In addition,we observe a four-monthly variation with peaks occurring usually in April,August,December in the northern hemisphere and in February,June,October in the southern hemisphere,respectively,above 85 km in middle latitudes,which has been seldom reported in gravity wave activity.In order to study the dissipation of gravity wave propagation,we calculate the gravity wave dissipation ratio,which is defined as the ratio of the gravity wave growth scale height to the atmosphere density scale height.The height variation of the dissipation ratio indicates that strong gravity wave dissipation mainly concentrates in the three height regions:the stratosphere(30–60 km),the mesopause(around 85 km)and the low thermosphere(above 100 km).Besides,gravity wave energy enhancement can be also observed in the background atmosphere.SHUAI Jing ZHANG ShaoDong HUANG ChunMing YI Fan HUANG KaiMing GAN Quan GONG Yun 2014Science China(Technological Sciences)2014,57,5:5
