| 1 | Effects of electroacupuncture and Chinese kidney-nourishing medicine on polycystic ovary syndrome in obese patients显示文摘OBJECTIVE: To explore the effect of electroacupuncture and Chinese kidney-nourishing medicine on insulin (INS), adiponectin (APN), leptin (LEP), and glucolipid metabolism of obese patients with polycystic ovary syndrome (PCOS). METHODS: Sixty-seven obese PCOS patients were randomly divided into two groups. Thirty-three patients in the acupuncture-medicine group were treated three times a week with electroacupuncture at the Tianshu (ST 25), Zhongwan (CV 12), Qihai (CV 6), Sanyinjiao (SP 6), Geshu (BL 17), and Cil-iao (BL 32) acupoints. They also took the Chinese drug, Tiankui capsule, for 3 months as a course of treatment. Point-taking and treatment in the electroacupuncture group of 34 patients was the same as those in the acupuncture-medicine group. We observed and compared the changes in the obesity-related indexes of body weight (BW), body mass index (BMI), and waist-hip ratio (WHR), as well as fasting plasma glucose (FPG), fasting insulin (FINS), APN, and LEP. RESULTS: BW, BMI, WHR, and FINS decreased and insulin sensitivity index (ISI) and APN were higher in the acupuncture-medicine group than in the electroacupuncture group (P<0.01). There was no obvious difference in LEP between the two groups (P>0.05). CONCLUSION: Acupuncture combined with medicine is better than just electroacupuncture for obese PCOS patients by improving obesity-related indexes, insulin sensitivity, and APN level. This indicates that acupuncture-medicine therapy is worth clinical popularization. | Liqing Yu Yanjun Liao Huangan Wu Jimeng Zhao Luyi Wu Yin Shi Jianqiao Fang | 2013 | Journal of Traditional Chinese Medicine2013，33，3： | 15 |
| 2 | Antisense MMP-9 RNA inhibits malignant glioma cell growth in vitro and in vivo显示文摘The matrix-degrading metalloproteinases (MMPs), particularly MMP-9, play important roles in the pathogenesis and development of malignant gliomas. In the present study, the oncogenic role of MMP-9 in malignant glioma cells was investigated via antisense RNA blockade in vitro and in vivo. TJ905 malignant glioma cells were transfected with pcDNA3.0 vector expressing antisense MMP-9 RNA (pcDNA-AS-MMP9), which significantly decreased MMP-9 expression, and cell proliferation was assessed. For in vivo studies, U251 cells, a human malignant glioma cell line, were implanted subcutaneously into 4-to 6-week-old BALB/c nude mice. The mice bearing well-established U251 gliomas were treated with intratumoral pcDNA-AS-MMP9-Lipofectamine complex (AS-MMP-9-treated group), subcutaneous injection of endostatin (endostatin-treated group), or both (combined therapy group). Mice treated with pcDNA (empty vector)-Lipofectamine served as the control group. Four or eight weeks later, the volume and weight of tumor, MMP-9 expression, microvessel density and proliferative activity were assayed. We demonstrate that pcDNA-AS-MMP9 significantly decreased MMP-9 expression and inhibited glioma cell proliferation. Volume and weight of tumor, MMP-9 expression, microvessel density and proliferative activity in the antisense-MMP-9-treated and therapeutic alliance groups were significantly lower than those in the control group. The results suggest that MMP-9 not only promotes malignant glioma cell invasiveness, but also affects tumor cell proliferation. Blocking the expression of MMP-9 with antisense RNA substantially suppresses the malignant phenotype of glioma cells, and thus can be used as an effective therapeutic strategy for malignant gliomas. | Cuiyun Sun Qian Wang Hongxu Zhou Shizhu Yu Alain R.

| 3 | Spatiotemporal Variations and Regional Transport of Air Pollutants in Two Urban Agglomerations in Northeast China Plain显示文摘Characteristics of air pollution in Northeast China(NEC) received less research attention in the past comparing to other heavily polluted regions in China.Spatiotemporal variations of six criteria air pollutants(PM10, PM2.5, SO2, NO2, O3 and CO) in Central Liaoning Urban Agglomeration(CLUA) and Harbin-Changchun Urban Agglomeration(HCUA) in NEC Plain were analyzed in this study based on three-year hourly observations of air pollutants and meteorological variables from 2015 to 2017.The results indicated that the annual mean concentrations of air pollutants are generally higher in the middle and southern regions in NEC Plain and lower in the northern region.Megacities such as Shenyang, Harbin and Changchun experience severe air pollution, with a three-year averaged air quality index(AQI) larger than 80, far exceeding the daily AQI standard at the first-level of 50 in China.The annual mean PM and SO2 concentrations decrease most significantly in NEC urban agglomerations from 2015 to 2017, followed by CO and NO2, while O3 shows a slight increasing trend.All the six pollutants exhibit obvious seasonal and diurnal variations, and these variations are dictated by local emission and meteorological conditions.PM2.5 and O3 concentrations in NEC urban agglomerations strongly depend on wind conditions.High O3 concentrations at different cities usually occur in presence of strong winds but are independent on wind direction(WD), while high PM2.5 is usually accompanied by weak winds and poor dispersion condition, and sometimes also occur when the northerly or southerly winds are strong.Regional transport of air pollutants between NEC urban agglomerations is common.A severe haze event on November 1–4, 2017 is examined to demonstrate the role of regional transport on pollution. | LI Xiaolan HU Xiaoming SHI Shuaiyi SHEN Lidu LUAN Lan MA Yanjun | 2019 | Chinese Geographical Science2019，29，6： | 9 |

| 5 | Orbital-scale Asian summer monsoon variations:Paradox and exploration显示文摘The Asian summer monsoon(ASM) is a vast climate system, whose variability is critical to the livelihoods of billions of people across the Asian continent. During the past half-century, much progress has been made in understanding variations on a wide range of timescales, yet several significant issues remain unresolved. Of note are two long-standing problems concerning orbital-scale variations of the ASM.(1) Chinese loess magnetic susceptibility records show a persistent glacial-interglacial dominated ~100 kyr(thousand years) periodicity, while the cave oxygen-isotope(δ18 O) records reveal periodicity in an almost pure precession band(~20 kyr periodicity)—the 'Chinese 100 kyr problem'.(2) ASM records from the Arabian Sea and other oceans surrounding the Asian continent show a significant lag of 8–10 kyr to Northern Hemisphere summer insolation(NHSI), whereas the Asian cave δ18 O records follow NHSI without a significant lag—a discrepancy termed the 'sea-land precession-phase paradox'. How can we reconcile these differences? Recent and more refined model simulations now provide spatial patterns of rainfall and wind across the precession cycle, revealing distinct regional divergences in the ASM domain, which can well explain a large portion of the disparities between the loess, marine, and cave proxy records. Overall, we also find that the loess, marine, and cave records are indeed complementary rather than incompatible, with each record preferentially describing a certain aspect of ASM dynamics. Our study provides new insight into the understanding of different hydroclimatic proxies and largely reconciles the 'Chinese 100 kyr problem' and 'sea-land precession-phase paradox'. | Hai CHENG Haiwei ZHANG Yanjun CAI Zhengguo SHI Liang YI Chenglong DENG Qingzhen HAO Youbing PENG Ashish SINHA Hanying LI Jingyao ZHAO Ye TIAN Jonathan BAKER Carlos PEREZ-MEJIAS | 2021 | Science China Earth Sciences2021，64，4： | 6 |
| 6 | Warm temperature compromises JA-regulated basal resistance to enhance Magnaporthe oryzae infection in rice显示文摘Changes in global temperatures profoundly affect the occurrence of plant diseases.It is well known that rice blast can easily become epidemic in relatively warm weather.However,the molecular mechanism remains unclear.In this study,we show that enhanced blast development at a warm temperature(22C)compared with the normal growth temperature(28C)is rice plant-determined.Comparative transcriptome analysis revealed that jasmonic acid(JA)biosynthesis and signaling genes in rice could be effectively induced by Magnaporthe oryzae at 28C but not at 22C.Phenotypic analyses of the osaoc1 and osmyc2 mutants,OsCOI1 RNAi lines,and OsMYC2-OE plants further demonstrated that compromised M.oryzaeinduced JA biosynthesis and signaling lead to enhanced blast susceptibility at the warm temperature.Consistent with these results,we found that exogenous application of methyl jasmonate served as an effective strategy for improving blast resistance under the warm environmental conditions.Furthermore,decreased activation of JA signaling resulted in the downregulated expression of some key basal resistance genes at 22C when compared with 28C.Among these affected genes,OsCEBiP(chitin elicitorbinding protein precursor)was found to be directly regulated by OsMYB22 and its interacting protein OsMYC2,a key component of JA signaling,and this contributed to temperature-modulated blast resistance.Taken together,these results suggest that warm temperature compromises basal resistance in rice and enhances M.oryzae infection by reducing JA biosynthesis and signaling,providing potential new strategies for managing rice blast disease under warm climate conditions. | Jiehua Qiu Junhui Xie Ya Chen Zhenan Shen Huanbin Shi Naweed I.Naqvi Qian Qian Yan Liang Yanjun Kou | 2022 | Molecular Plant2022，15，4： | 5 |

| 9 | PrP mutants with different numbers of octarepeat sequences are more susceptible to the oxidative stress显示文摘One of the physiological functions of cellular prion protein(PrP C )is believed to work as a cellular resistance to oxidative stress,in which the octarepeats region within PrP plays an important role.However,the detailed mechanism is less clear.In this study,the expressing plasmids of wild-type PrP (PrP-PG5)and various PrP mutants containing 0(PrP-PG0),9(PrP-PG9)and 12(PrP-PG12)octarepeats were generated and PrP proteins were expressed both in E.coli and in mammalian cells.Protein aggregation and formation of carbonyl groups were clearly seen in the recombinant PrPs expressed from E.coli after treatment of H2O2.MTT and trypan blue staining assays revealed that the cells expressing the mutated PrPs within octarepeats are less viable than the cells expressing wild-type PrP.Statistically significant high levels of intracellular free radicals and low levels of glutathione peroxidase were observed in the cells transfected with plasmids containing deleted or inserted octarepeats.Remarkably more productions of carbonyl groups were detected in the cells expressing PrPs with deleted and inserted octarepeats after exposing to H2O2.Furthermore,cells expressing wild-type PrP showed stronger resistant activity to the challenge of H2O2 at certain extent than the mutated PrPs and mock. These data provided the evidences that the octarepeats number within PrP is critical for maintaining its activity of antioxidation.Loss of its protective function against oxidative stress may be one of the possible pathways for the mutated PrPs to involve in the pathogenesis of familial Creutzfeldt-Jacob diseases. | AN Run1 ,2,DONG ChenFang 2,LEI YanJun 1,2,HAN Lu 2,LI Ping 2,CHEN JianMing 2,WANG GuiRong 2, SHI Qi 2 ,GAO Chen 2 ,JIANG HuiYing 2 ,ZHOU Wei 2 ,HAN Jun 2 ,CHU YongLie 1 ,DONG XiaoPing 2 1School of Medicine,Xi’an JiaoTong University,Xi’an 710061,China 2State Key Laboratory for Infectious Disease Prevention and Control,National Institute for Viral Disease Control and Prevention, Chinese Center for Disease Control and Prevention,YingXin Rd 100,Beijing 100052,China | 2008 | Science China(Life Sciences)2008，51，7： | 3 |
| 10 | Physical statistical algorithm for precipitable water vapor inversion on land surface based on multi-source remotely sensed data显示文摘Water vapor plays a crucial role in atmospheric processes that act over a wide range of temporal and spatial scales, from global climate to micrometeorology. The determination of water vapor distribution in the atmosphere and its changing pattern is very important. Although atmospheric scientists have developed a variety of means to measure precipitable water vapor(PWV) using remote sensing data that have been widely used, there are some limitations in using one kind satellite measurements for PWV retrieval over land. In this paper, a new algorithm is proposed for retrieving PWV over land by combining different kinds of remote sensing data and it would work well under the cloud weather conditions. The PWV retrieval algorithm based on near infrared data is more suitable to clear sky conditions with high precision. The 23.5 GHz microwave remote sensing data is sensitive to water vapor and powerful in cloud-covered areas because of its longer wavelengths that permit viewing into and through the atmosphere. Therefore, the PWV retrieval results from near infrared data and the indices combined by microwave bands remote sensing data which are sensitive to water vapor will be regressed to generate the equation for PWV retrieval under cloud covered areas. The algorithm developed in this paper has the potential to detect PWV under all weather conditions and makes an excellent complement to PWV retrieved by near infrared data. Different types of surface exert different depolarization effects on surface emissions, which would increase the complexity of the algorithm. In this paper, MODIS surface classification data was used to consider this influence. Compared with the GPS results, the root mean square error of our algorithm is 8 mm for cloud covered area. Regional consistency was found between the results from MODIS and our algorithm. Our algorithm can yield reasonable results on the surfaces covered by cloud where MODIS cannot be used to retrieve PWV. | WANG YongQian SHI JianCheng WANG Hao FENG WenLan WANG YanJun | 2015 | Science China Earth Sciences2015，58，12： | 3 |

| 12 | Supplement and optimization of classical capillary number experimental curve for enhanced oil recovery by combination flooding显示文摘In the middle of the last century,American scientists put forward the concept of capillary number and obtained the relation curve between capillary number and residual oil through experiments.They revealed that the corresponding residual oil saturation decreased with increasing of capillary number;after capillary number reached up to a limit,residual oil saturation would become stable and did not decrease.These important achievements laid a theoretical base for enhanced oil recovery with chemical flooding.On the basis of the theory,scholars developed chemical flooding numerical simulation software UTCHEM.During the numerical simulation study of combination flooding,the authors found that as the capillary number is higher than the limit capillary number,the changes of the residual oil saturation along with the capillary number differ from the classical capillary number curve.Oil displacement experiments prove that there are defects in classic capillary number experimental curve and it is necessary to mend and improve.Capillary number‘calculation’curve is obtained with a method of numerical simulation calculation and a complete description of capillary number curve is provided;On this basis,combination flooding capillary number experimental curve QL is obtained through experiments,which is different from the classical capillary curve;and based on which,an expression of corresponding combination flooding relative permeability curve QL is given and the corresponding relative permeability parameters are determined with experiments.Further oil displacement experiment research recognizes the cause of the singular changes of the capillary number curve.'Combination flooding capillary number experimental curve QL'and'combination flooding relative permeability curve QL'are written in combination flooding software IMCFS,providing an effective technical support for the application of combination flooding technical research. | QI LianQing LIU ZongZhao YANG ChengZhi YIN YanJun HOU JiRui ZHANG Jian HUANG Bo SHI FengGang | 2014 | Science China(Technological Sciences)2014，57，11： | 2 |
| 13 | Early Paleozoic adakite in the Liuyuan area from the Beishan orogenic belt,NW Gansu Province:Petrogenesis and implication for tectonic setting显示文摘The Liuyuan area,which is located on the southern margin of the Beishan orogenic belt,develops abundant Early Paleozic granitoids.SHRIMP zircon U-Pb dating yielded a weighted mean 206Pb/238U age of 421±8 Ma for the Liuyuan granodiorite(Zhao Zehui et al.,2007),implying its Late Silurian intrusion.Geochemical compositions showed that the Liuyuan granodiorite is characterized by high SiO2(65.01%-67.31%),A12O3(17.17%-18.05%) and Na2O(Na2O/K2O=1.67-1.87) but low Mg# contents calculated as 100×Mg2+/(Mg2++∑Fe2+) from 28.77 to 31.15,as well as being enriched in Sr(472×10-6-517×10-6) but depleted in Yb(1.2×10-6-1.42×10-6) and Y(12.8×10-6-14×10-6).The REEs are characterized by right-inclined patterns with LREE enrichment,HREE depletion and slightly negative Eu anomalies(Eu/Eu*=0.91-0.97).Major and trace elements indicate that the granodiorite is an adakite.The Nb/Ta values of the granodiorite vary from 10.80 to 18.01 and Nb/U from 6.32 to 10.09,both lying between the values of the crust and the mantle.The rock has low εNd(t) values(-2.5--0.8) and high ISr(0.706321-0.706495).Geochemical and Sr-Nd isotopic compositions indicate that the Liuyuan granodiorite is possibly derived from partial melting of thickening lower crust,related to mantle underplating.The Yb-Ta and Y+Nb-Rb discriminant diagrams imply the Liuyuan granodiorite intruded in a local extensional tectonic setting during late collision.Combined with previous studies on geochronology,geochemistry and tectonic setting of granitoids,we interprete that the constraint of this adakite in the Liuyuan area indicates that the tectonic setting may have transformed from collision to extension during the Early Devonian. | Li, Yanjun Wei, Junhao Tan, Jun Fu, Lebing Liu, Xuntao Kong, Lingjun Jiang, Yongjian Shi, Wenjie | 2011 | Chinese Journal Of Geochemistry2011，30，2： | 2 |

| 15 | Putative Phosphatase UvPsr1 Is Required for Mycelial Growth, Conidiation, Stress Response and Pathogenicity in Ustilaginonidea virens显示文摘Ustilaginoidea virens is the causal agent of rice false smut,which can be a highly destructive disease of rice.The plasma membrane phosphatase Psr1 proteins,which act as a regulator of the salinity stress response in yeast,are widely distributed across fungi,but their functional characterization is sketchy.In this study,we characterized the functions of Psr1 protein,UvPsr1,in U.virens.Analyses of the AUvpsr1 and its complementation strain showed that UvPsr1 is required for normal mycelial growth,conidiation and tolerance to oxidative,osmotic and cell wall stresses.When rice panicles were inoculated with the AUvpsr1 strains,no symptoms of false smut disease developed,showing that UvPSR1 also contributes to the pathogenicity of the fungus.The deletion mutant of UvPSR1 also appeared to produce a smaller titer of toxic compounds able to inhibit elongation of the germinated seeds.In conclusion,our results indicated that UvPsr1 is a new pathogenic factor of U.virens. | Xiong Meng Meng Shuai Qiu Jiehua Shi Huanbin Shen Xiangling Kou Yanjun | 2020 | Rice science2020，27，6： | 2 |

| 17 | A Multi-Scale Thermal Analysis Method for Data Centers with Application in a Ship Data Center显示文摘Thermal analysis of data centers is in urgent need to ensure that computer chips remain below the critical temperature while the energy consumption for cooling can be reduced.It is difficult to obtain detailed hotspot locations and temperatures of chips in large data centers containing hundreds of racks or more by direct measurement.In this paper,a multi-scale thermal analysis method is proposed that can predict the temperature distribution of chips and solder balls in data centers.The multi-scale model is divided into six scales:room,rack,server,Insulated-Gate Bipolar Transistor(IGBT),chip and solder ball.A concept of sub-model is proposed and the six levels are organized into four simulation sub-models.Sub-model 1 contains Room,Rack and Server(RRS);Sub-model 2 contains Server and IGBT(SI);Sub-model 3 contains IGBT and Chip(IC),and Sub-model 4 contains Chip and Solder-ball(CS).These four sub-models are one-way coupled by transmitting their results as boundary conditions between levels.The full-field simulation method is employed to verify the efficiency and accuracy of multi-scale simulation method for a single-rack data center.The two simulation results show that the highest temperature emerges in the same location.The Single-rack Full-field Model(SRFFM)costs 2.5 times more computational time than that with Single-rack Multi-scale Model(SRMSM).The deviation of the highest temperature of chips and solder balls are 1.57℃and 0.2℃between the two models which indicates that the multi-scale simulation method has good prospect in the data center thermal simulation.Finally,the multi-scale thermal analysis method is applied to a ship data center with 15 racks. | DAI Yanjun ZHAO Jie SHI Jiwei WANG Wei TAO Wenquan | 2021 | Journal of Thermal Science2021，30，6： | 1 |
