| 1 | A Survey on Terahertz Communications显示文摘With the exponential growth of the data traffic in wireless communication systems, terahertz(THz) frequency band is envisioned as a promising candidate to support ultra-broadband for future beyond fifth generation(5G), bridging the gap between millimeter wave(mmWave) and optical frequency ranges. The purpose of this paper is to provide a comprehensive literature review on the development towards THz communications and presents some key technologies faced in THz wireless communication systems. Firstly, despite the substantial hardware problems that have to be developed in terms of the THz solid state superheterodyne receiver, high speed THz modulators and THz antennas, the practical THz channel model and the efficient THz beamforming are also described to compensate for the severe path attenuation. Moreover, two different kinds of lab-level THz communication systems are introduced minutely, named a solid state THz communication system and a spatial direct modulation THz communication system, respectively. The solid state THz system converts intermediate frequency(IF) modulated signal to THz frequency while the direct modulation THz system allows the high power THz sources to input for approving the relatively long distance communications. Finally, we discuss several potential application scenarios as well as some vital technical challenges that will be encountered in the future THz communications. | Zhi Chen Xinying Ma Bo Zhang Yaxin Zhang Zhongqian Niu Ningyuan Kuang Wenjie Chen Lingxiang Li Shaoqian Li | 2019 | China Communications2019，16，2： | 43 |
| 2 | Sequential transcatheter arterial chemoembolization,three-dimensional conformal radiotherapy,and high-intensity focused ultrasound treatment for unresectable hepatocellular carcinoma patients显示文摘The purpose of this study was to evaluate the outcome of patients with unresectable hepatocellular carcinoma(HCC) treated by sequential therapy of transcatheter arterial chemoembolization(TACE),three-dimensional conformal radiotherapy(3-DCRT) and high-intensity focused ultrasound(HIFU).From October,2005 to September,2010,120 patients with unresectable HCC received the sequential treatments of several courses of TACE followed in 2-4 weeks by 3-DCRT and then a single session of HIFU with a curative intent.The median tumor irradiation dose was 40 Gy.Tumor response,toxicity and overall survival rate were analyzed.Clinicopathologic factors affecting the primary technique effectiveness and overall survival rates were investigated by univariate analysis or multivariate analysis.All 120 HCC patients were followed up by the last follow-up time.Among these patients,hepatic toxicities due to treatment were notable in 9 cases.Gastrointestinal bleeding after the overall treatment occurred in 2 cases,leukopenia of grade III was detected in 1 case,radiation-induced liver disease(RILD) was observed in 2 patients,and first-and second-degree skin burn around the HIFU treatment zone were observed in 2 patients and 1 patient,respectively.Among 120 patients,23,83 and 14 cases achieved partial response,stable disease and progressive disease,respectively.The overall survival rates at 1 year,3 years and 5 years were 70%,35% and 15%,respectively,with a median survival time of 26 months.Both Child-Pugh liver function grading and radiation dose were determined to be independent predictors for overall survival revealed by the multivariate analysis.It is concluded that the sequential therapy of TACE,3-DCRT and HIFU is a promising therapeutic regimen for unresectable HCC. | Shengfa Ni Lingxiang Liu Yongqian Shu | 2012 | The Journal of Biomedical Research2012，26，4： | 9 |
| 3 | Efficacy of herb-partitioned moxibustion at Qihai(CV 6) and bilateral Tianshu(ST 25) on colonic damage and the TLR4/NF-κB signaling pathway in rats with Crohn's disease显示文摘OBJECTIVE: To observe the effect of stimulating Qihai(CV 6) and bilateral Tianshu(ST 25) with herb-partitioned moxibustion(HPM) in rats with Crohn's disease(CD), and to investigate the possible anti-inflammatory mechanism of HPM.METHODS: Forty rats were randomly divided into four groups(n = 10 rats per group): normal control(NC), model control(MC), mesalamine(MES), and HPM. The CD rat model was established in the MC,MES, and HPM groups by administering a mixture of trinitrobenzenesulfonic acid and alcohol via enema. The HPM group received HPM on Qihai(CV 6)and bilateral Tianshu(ST 25), while the MES group received intragastric mesalamine. Colonic histomorphological scores, and serum concentrations of tumor necrosis factor α(TNF-α) and interleukin 1β(IL-1β) were assessed to evaluate the effects of HPM on colonic reparation and anti-inflammation.The expressions of Toll-like receptor 4(TLR-4), nuclear factor κB inhibitor α(IκB-α), IκB kinase α/β(IKKα/β), and NF-κB p65 were further analyzed to investigate the regulatory effects of the interventions on the TLR4/NF-κB pathway.RESULTS: CD rats showed inflammatory colonic damage and increased serum concentrations of TNF-α and IL-1β. The expressions of TLR4, IKKα/β,and NF-κB p65 in the colons of CD rats were significantly increased compared with the NC group,while the expression of IκBα(a key negative regulator of NF-κB p65) was decreased. HPM significantly mitigated colonic damage and reduced the serum concentrations of TNF-α and IL-1β. HPM downregulated the expressions of TLR4, IKKα/β, and NF-κB p65 in the colon, and upregulated the expression of IκBα. The effects of HPM in CD rats were similar to those of mesalamine.CONCLUSION: HPM alleviates colonic inflammation in CD rats. This may be achieved through regulation of TLR4, which induces NF-κB signal transduction. | Zhang Dan Wei Kai Ma Xiaopeng Wu Huangan Hong Jue Zhang Cuihong Wu Lingxiang Yan Huang Liu Jie Zhu Yi Yang Ling | 2018 | Journal of Traditional Chinese Medicine2018，38，2： | 6 |

| 5 | The advanced development of molecular targeted therapy for hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC),one of the most common malignant tumors in China,severely threatens the life and health of patients.In recent years,precision medicine,clinical diagnoses,treatments,and innovative research have led to important breakthroughs in HCC care.The discovery of new biomarkers and the promotion of liquid biopsy technologies have greatly facilitated the early diagnosis and treatment of HCC.Progress in targeted therapy and immunotherapy has provided more choices for precise HCC treatment.Multiomics technologies,such as genomics,transcriptomics,and metabolomics,have enabled deeper understanding of the occurrence and development mechanisms,heterogeneity,and genetic mutation characteristics of HCC.The continued promotion and accurate typing of HCC,accurate guidance of treatment,and accurate prognostication have provided more treatment opportunities and prolonged survival timelines for patients with HCC.Innovative HCC research providing an in-depth understanding of the biological characteristics of HCC will be translated into accurate clinical practices for the diagnosis and treatment of HCC. | Tao Yan Lingxiang Yu Ning Zhang Caiyun Peng Guodong Su Yi Jing Linzhi Zhang Tong Wu Jiamin Cheng Qian Guo Xiaoliang Shi Yinying Lu | 2022 | Cancer Biology & Medicine2022，19，6： | 2 |
| 6 | Reliable and Energy-Aware Job Offloading at Terahertz Frequencies for Mobile Edge Computing显示文摘In this paper,we co-design the transmission power and the offloading strategy for job offloading to a mobile edge computing(MEC)server at Terahertz(THz)frequencies.The goal is to minimize the communication energy consumption while providing ultra-reliable low end-to-end latency(URLLC)services.To that end,we first establish a novel reliability framework,where the end-to-end(E2E)delay equals a weighted sum of the local computing delay,the communication delay and the edge computing delay,and the reliability is defined as the probability that the E2E delay remains below a certain pre-defined threshold.This reliability gives a full view of the statistics of the E2E delay,thus constituting advancement over prior works that have considered only average delays.Based on this framework,we establish the communication energy consumption minimization problem under URLLC constraints.This optimization problem is non-convex.To handle that issue,we first consider the special single-user case,where we derive the optimal solution by analyzing the structure of the optimization problem.Further,based on the analytical result for the single-user case,we decouple the optimization problem for multi-user scenarios into several sub-optimization problems and propose a sub-optimal algorithm to solve it.Numerical results verify the performance of the proposed algorithm. | Sha Xie Haoran Li Lingxiang Li Zhi Chen Shaoqian Li | 2020 | China Communications2020，17，12： | 2 |
| 7 | Assessing anxiety,depression,and stress among inpatients with cancer显示文摘Objective This study aimed to assess anxiety,depression,and stress among inpatients with cancer.Methods Two hundred thirty-five hospitalized patients with cancer were surveyed with the Depression Anxiety Stress Scales(simplified Chinese Version).The software program SPSS 25.0 was used for statistical analysis of the survey data.Results The average scores of depression,anxiety,and stress of inpatients with cancer were 12.17,11.84,and 13.98 respectively,which were higher than the normal range.The scores of anxiety and stress of inpatients with different caregivers were statistically different(P=0.024/0.036).The anxiety and stress scores of inpatients with spouses as caregivers were higher than those of inpatients with children as caregivers.There was a statistically significant difference in the incidence of stress between inpatients with cancer with religious beliefs and inpatients with cancer without religious beliefs(P=0.026),and those with religious beliefs had greater incidence of stress.The score of anxiety was significantly higher for inpatients with children than for inpatients without children(P=0.040).Conclusion The anxiety,depression,and stress levels of inpatients with cancer are relatively high.It is necessary to pay special attention to the psychological status of these patients during clinical diagnosis and treatment to improve their quality of life. | Honghong Xu Ruotong Xue Yi Cheng Yujie Zhang Jie Rao Mei Liu Shiying Yu Lingxiang Liu Yiqian Liu Yongqian Shu Liuqing Yang Hanping Shi | 2020 | Oncology and Translational Medicine2020，6，3： | 2 |
| 8 | Use of donor-specific red blood cell transfusions for patients undergoing liver transplantation during the COVID-19 pandemic显示文摘Background:Increased risks have been found for patients undergoing liver transplantation due to the blood supply shortage following the ongoing coronavirus disease 2019(COVID-19)pandemic.Hence,exploring a method to alleviate this dilemma is urgent.This phase I,nonrandomized,prospective trial aimed to evaluate the safety and feasibility of using donor-specific red blood cell transfusion(DRBCT)as an urgent measurement to alleviate the blood supply shortage in deceased donor liver transplantation(DDLT).Methods:The outcomes of 26 patients who received DRBCT and 37 patients in the control group who only received 3rd party packed red blood cells(pRBCs)transfusion between May 2020 and January 2021 were compared.Results:Patients receiving DRBCT did not develop transfusion-related complications,and the incidence of postoperative infection was similar to that in the control group(23.1%vs.18.9%,P=0.688).Because the patients received the red blood cells from organ donors,the median volume of intraoperative allogeneic red blood cell transfusion from blood bank was 4.0 U(IQR 1.1-8.0 U)in the DRBCT group,which is significantly lower than that(7.5 U,IQR 4.0-10.0 U)in the control group(P=0.018).The peak aspartate aminotransferase(AST)level was significantly lower in the DRBCT group than in the control group(P=0.008)and so were the AST levels in the first two days after the operation(P=0.006 and P=0.033).Conclusions:DRBCT is a safe and effective procedure to lower the need for blood supply and is associated with a reduction in AST levels after transplantation.DRBCT is beneficial to patients receiving life-saving transplantation without sufficient blood supply during the COVID-19 pandemic. | Tao Lv Xi Xu Jiulin Song Yifei Tan Li Jiang Jian Yang Diao He Lingxiang Kong Weiyi Zhang Panyu Chen Qiwen Xiang Tao Zhu Hong Wu Tianfu Wen Jiayin Yang | 2021 | Hepatobiliary Surgery and Nutrition2021，10，4： | 2 |

| 16 | Magnetotelluric study of the Xuefeng mountain area,Hu'nan Province,China显示文摘A magnetotelluric study was carried out in the Xuefeng mountain uplift belt and its western margins. A detailed investigation was made of the resistivity of the formations, and reliable data were obtained. The sedimentary cover and basement structure of the Xuefeng mountain area and the deep geological structure were analyzed in detail using magnetotelluric data from the twodimensional inversion of the resistivity profile data in combination with regional gravity and magnetic data. It was concluded that the tectonic movements were characterized by basement detachment, and north-south ramp.The study area can be divided into a southern uplift zone, a southern thrust-faulted zone, a central uplift zone, and a northern depression zone. This work has provided geophysical evidence that can be used in future studies of the tectonics and petroleum geology of this region. | Musen Chen Lingxiang Xue Yousheng Wang Shengjun Zhu | 2016 | Earthquake Science2016，29，2： | 1 |
