| 3 | Efficacy evaluation of summer acupoint application treatment on asthma patients: a two-year follow-up clinical study显示文摘OBJECTIVE: To evaluate the self-efficacy and satisfaction of asthma patients subjected to summer acupoint application treatment(SAAT).METHODS: A two-year follow-up clinical study was conducted. Patients with asthma were treated by applying a herbal paste onto the Feishu(BL 13) and Fengmen(BL 12) acupoints on the three hottest days of summer, according to the traditional Chinese calendar, from 2008 to 2010. During a two-year follow-up, these patients were asked tofill out a questionnaire evaluating asthma degree,exacerbation frequency, concomitant medications and self-satisfaction. The self-rate and doctor-report outcomes obtained in parallel were evaluated to assess the efficacy of SAAT.RESULTS: A total of 527 asthma patients were initially enrolled in this study, of which 97 elderly patients and those with more severe cases of asthma were lost to follow-up. Thus, a total of 430 patients were valid for analysis using self-rate data. Nevertheless, occasional negative returns were obtained;almost all of the outcomes were rated as 'No change', 'Moderate effective', or 'Very effective'. In addition, 80% of the patients were satisfied with this treatment. Moreover, 391(91.4%) patients were somewhat improved after SAAT in 2009, and further improvement was observed in 2010. After SAAT, the average asthma-degree score decreased from 5.3 in 2008 to 4 in 2009 and, subsequently to3.5 in 2010.CONCLUSION: With pronounced patient satisfaction, SAAT can reduce the exacerbation severity and frequency, concomitant medications and asthma degree. Prolonging the treatment course might enhance the efficacy of SAAT. | Wu Xiaqiu Peng Jin Li Guoqin Zhang Wei Liu Guangxia Liu Baoyan | 2015 | Journal of Traditional Chinese Medicine2015,35,1: | 7 |

| 5 | Distribution and mode of occurrence of uranium in bottom ash derived from high-germanium coals显示文摘The radioactivity of uranium in radioactive coal bottom ash(CBA) may be a potential danger to the ambient environment and human health. Concerning the limited research on the distribution and mode of occurrence of uranium in CBA, we herein report our investigations into this topic using a number of techniques including a five-step Tessier sequential extraction, hydrogen fluoride(HF) leaching, Siroquant(Rietveld) quantification, magnetic separation, and electron probe microanalysis(EPMA). The Tessier sequential extraction showed that the uranium in the residual and Fe–Mn oxide fractions was dominant(59.1%and 34.9%, respectively). The former was mainly incorporated into aluminosilicates,retained with glass and cristobalite, whereas the latter was especially enriched in the magnetic fraction, of which about 50% was present with magnetite(Fe_3O_4) and the rest in other iron oxides. In addition, the uranium in the magnetic fraction was 2.6 times that in the non-magnetic fraction. The experimental findings in this work may be important for establishing an effective strategy to reduce radioactivity from CBA for the protection of our local environment. | Yinglong Sun Guangxia Qi Xuefei Lei Hui Xu Lei Li Chao Yuan Yi Wang | 2016 | Journal of Environmental Sciences2016,28,5: | 3 |
| 6 | YB-1 stabilizes HIV-1 genomic RNA and enhances viral production显示文摘HIV-1 utilizes cellular factors for effi cient replication.The viral RNA is different from cellular mRNAs in many aspects,and is prone to attacks by cellular RNA quality control systems.To establish effective infection,the virus has evolved multiple mechanisms to protect its RNA.Here,we show that expression of the Y-box binding protein 1(YB-1)enhanced the production of HIV-1.Downregulation of endogenous YB-1 in producer cells decreased viral production.YB-1 increased viral protein expression by stabilizing HIV-1 RNAs.The stem loop 2 in the HIV-1 RNA packaging signal was mapped to be the YB-1-responsive element.Taken together,these results indicate that YB-1 stabilizes HIV-1 genomic RNA and thereby enhances HIV-1 gene expression and viral production. | Xin Mu Wei Li Xinlu Wang Guangxia Gao | 2013 | Protein & Cell2013,4,8: | 2 |
| 7 | Safe Navigation for UAV-Enabled Data Dissemination by Deep Reinforcement Learning in Unknown Environments显示文摘Unmanned aerial vehicles(UAVs) are increasingly considered in safe autonomous navigation systems to explore unknown environments where UAVs are equipped with multiple sensors to perceive the surroundings. However, how to achieve UAVenabled data dissemination and also ensure safe navigation synchronously is a new challenge. In this paper, our goal is minimizing the whole weighted sum of the UAV’s task completion time while satisfying the data transmission task requirement and the UAV’s feasible flight region constraints. However, it is unable to be solved via standard optimization methods mainly on account of lacking a tractable and accurate system model in practice. To overcome this tough issue,we propose a new solution approach by utilizing the most advanced dueling double deep Q network(dueling DDQN) with multi-step learning. Specifically, to improve the algorithm, the extra labels are added to the primitive states. Simulation results indicate the validity and performance superiority of the proposed algorithm under different data thresholds compared with two other benchmarks. | Fei Huang Guangxia Li Shiwei Tian Jin Chen Guangteng Fan Jinghui Chang | 2022 | China Communications2022,19,1: | 1 |

| 10 | Navigation for UAV Pair-Supported Relaying in Unknown IoT Systems with Deep Reinforcement Learning显示文摘Unmanned aerial vehicles(UAVs) have recently been regarded as a promising technology in Internet of things(IoT). UAVs functioned as intermediate relay nodes are capable of establishing uninterrupted and high-quality communication links between remotely deployed IoT devices and the destination. Multiple UAVs are required to be deployed due to their limited onboard energy. We study a UAV pair-supported relaying in unknown IoT systems, which consists of transmitter and receiver. Our goal is that transmitter gathers the data from each device then transfers the information to receiver,and receiver finally transmits the information to the destination, while meeting the constraint that the amount of information received from each device reaches a certain threshold. This is an optimization problem with highly coupled variables, such as trajectories of transmitter and receiver. On account of no prior knowledge of the environment, a dueling double deep Q network(dueling DDQN) algorithm is proposed to solve the problem.Whether it is in the phase of transmitter’s receiving information or the phase of transmitter’s forwarding information to receiver, the effectiveness and superiority of the proposed algorithm is demonstrated by extensive simulationsin in comparison to some base schemes under different scenarios. | HUANG Fei LI Guangxia WANG Haichao TIAN Shiwei YANG Yang CHANG Jinghui | 2022 | Chinese Journal of Electronics2022,31,3: | 1 |

| 18 | Influence of temperature rate on transitory internal friction during reverse martensitic transformation for Ti_(50)Ni_(27)Cu_(23) alloy显示文摘Internal friction (IF) spectra during reverse martensitic transformation from 35 to 135°C at different temperature rates of 0.5,0.75,and 1°C/min for Ti50Ni27Cu23 shape memory alloy (SMA) samples were measured with a dynamic mechanical analyzer,respectively.The IF spectra were characterized by IF peak increasing progressively and peak shifting toward high temperature with an increase in temperature rate.An iterative approach was used to calculate the precise intrinsic and approximate transitory IF contributions to the normal IF spectrum.The quantitatively analyzed results indicate that the transitory IF of this alloy is nonlinearly dependent on the temperature rate and obeys a power law with a power coefficient of 0.55.The predicted and experimental IF spectra at different temperature rates of 0.75 and 1°C/min agree well with each other,respectively. | LI Yonghua,QI Guangxia,WANG Zhongtang,LI Yuhai,and DENG Ziyu School of Materials Science and Engineering,Shenyang Ligong University,Shenyang 110159,China | 2010 | Rare Metals2010,29,3: | 1 |
