| 2 | Panax notoginseng saponins ameliorates experimental hepatic fibrosis and hepatic stellate cell proliferation by inhibiting the Jak2/Stat3 pathways显示文摘OBJECTIVE: To investigate the inhibitory effect of Panax notoginseng saponins(PNS) on liver fibrosis and explore the underlying mechanisms.METHODS: Carbon tetrachloride(CCl4)-treated rats and hepatic stellate cells(HSCs) were used. The effect of PNS on CCl4-induced liver fibrosis was studied with histochemical and biochemical analysis.Transforming growth factor(TGF)-β1, α-smooth muscle actin(α-SMA), and collagen Ι m RNA expression were determined by reverse transcriptase-polymerase chain reaction(RT-PCR). Meanwhile, the protein expression levels of α-SMA, collagen Ι, phosphorylation-Janus activated kinase signal transducer(p-Jak2) / Jak2, and phosphorylation-activator of transcription(p-Stat)3 / Stat3 were determined by immunohistochemistry and / or immunoblotting.RESULTS: PNS treatment significantly improved the liver function of rats as indicated by decreased serum enzymatic activities of alanine aminotransferase and aspartate aminotransferase. Histopathological results indicated that PNS alleviated liver damage and reduced the formation of fibrous septa. Moreover, PNS significantly decreased liver hydroxyproline and significantly attenuated expressions of collagen Ⅰ, α-SMA, TGF-β1, p-Jak2 / Jak2,and p-Stat3 / Stat3 in the rat liver fibrosis model and HSCs.CONCLUSION: PNS can relieve liver fibrosis by modulating Jak2/Stat3 signaling transduction pathway, which may be one of its mechanisms to suppress hepatic fibrosis. | Jiang Hui Gao Jiarong Wang Yongzhong Zhang Jiafu Han Yanquan Wei Liangbing Liu Xiaochuang Wu Jian | 2016 | Journal of Traditional Chinese Medicine2016，36，2： | 28 |

| 4 | Chinese expert consensus statement on the diagnosis and treatment of fulminant myocarditis显示文摘Fulminant myocarditis is primarily caused by infection with any number of a variety of viruses. It arises quickly, progresses rapidly, and may lead to severe heart failure or circulatory failure presenting as rapid-onset hypotension and cardiogenic shock,with mortality rates as high as 50%–70%. Most importantly, there are no treatment options, guidelines or an expert consensus statement. Here, we provide the first expert consensus, the Chinese Society of Cardiology Expert Consensus Statement on the Diagnosis and Treatment of Fulminant Myocarditis, based on data from our recent clinical trial(NCT03268642). In this statement, we describe the clinical features and diagnostic criteria of fulminant myocarditis, and importantly, for the first time,we describe a new treatment regimen termed life support-based comprehensive treatment regimen. The core content of this treatment regimen includes(i) mechanical life support(applications of mechanical respirators and circulatory support systems,including intraaortic balloon pump and extracorporeal membrane oxygenation),(ii) immunological modulation by using sufficient doses of glucocorticoid, immunoglobulin and(iii) antiviral reagents using neuraminidase inhibitor. The proper application of this treatment regimen may and has helped to save the lives of many patients with fulminant myocarditis. | Daowen Wang Sheng Li Jiangang Jiang Jiangtao Yan Chunxia Zhao Yan Wang Yexin Ma Hesong Zeng Xiaomei Guo Hong Wang Jiarong Tang Houjuan Zuo Li Lin Guanglin Cui Section of Precision Medicine Group of Chinese Society of Cardiology,Editorial Board of Chinese Journal of Cardiology &Working Group of Adult Fulminant Myocarditis | 2019 | Science China(Life Sciences)2019，62，2： | 18 |
| 5 | High energy soliton pulse generation by a magnetron-sputtering-deposition-grown MoTe_2 saturable absorber显示文摘The pulse energy in the ultrafast soliton fiber laser oscillators is usually limited by the well-known wave-breaking phenomenon owing to the absence of a desirable real saturable absorber(SA) with high power tolerance and large modulation depth. Here, we report a type of microfiber-based MoTe_2 SA fabricated by the magnetron-sputtering deposition(MSD) method. High-energy wave-breaking free soliton pulses were generated with pulse duration/pulse energy/average output power of 229 fs/2.14 nJ/57 mW in the 1.5 μm regime and 1.3 ps/13.8 nJ/212 mW in the 2 μm regime, respectively. To our knowledge, the generated soliton pulses at 1.5 μm had the shortest pulse duration and the highest output power among the reported erbium-doped fiber lasers mode locked by transition metal dichalcogenides. Moreover, this was the first demonstration of a MoTe_2-based SA in fiber lasers in the 2 μm regime, and the pulse energy/output power are the highest in the reported thulium-doped fiber lasers mode locked by two-dimensional materials. Our results suggest that a microfiber-based MoTe_2 SA could be used as an excellent photonic device for ultrafast pulse generation, and the MSD technique opens a promising route to produce a high-performance SA with high power tolerance and large modulation depth, which are beneficial for high-energy wave-breaking free pulse generation. | JINTAO WANG ZIKE JIANG HAO CHEN JIARONG LI JINDE YIN JINZHANG WANG TINGCHAO HE PEIGUANG YAN SHUANGCHEN RUAN | 2018 | Photonics Research2018，6，6： | 14 |

| 7 | Diagnosabilities of exchanged hypercube networks under the pessimistic one-step diagnosis strategy显示文摘The exchanged hypercube EH(s, t)(where s≥1 and t ≥1) is obtained by systematically reducing links from a regular hypercube Qs+t+1. One-step diagnosis of exchanged hypercubes which involves only one testing phase during which processors test each other is discussed. The diagnosabilities of exchanged hypercubes are studied by using the pessimistic one-step diagnosis strategy under two kinds of diagnosis models: the PMC model and the M M*model. The main results presented here are the two proofs that the degree of diagnosability of the EH(s, t) under pessimistic one-step t1/t1 fault diagnosis strategy is 2s where1≤s≤t(respectively, 2t, where 1≤t≤s) based on the PMC model and that it is also 2s where 1≤s≤t(respectively, 2t,where 1≤t≤s) based on the M M*model. | Jiarong Liang Ying Huang Liangcheng Ye | 2015 | Journal of Systems Engineering and Electronics2015，26，2： | 12 |
| 8 | Photoreduction of CO_2 to methanol over Bi_2S_3/CdS photocatalyst under visible light irradiation显示文摘The Bi2S3,CdS and Bi2S3/CdS photocatalysts were prepared by direct reactions between their corresponding salt and thiourea in a hy- drothermal autoclave.The photocatalytic activities of these photocatalysts for reducing CO2 to CH3OH under visible light irradiation have been investigated.The results show that the photocatalytic activity and visible light response of Bi2S3 are higher than those of CdS.The Bi2S3 modification can enhance the photocatalytic activity and visible light response of CdS.The photocatalytic activity of Bi2S3/CdS hetero-junction photocatalyst was the highest and the highest yields of methanol was 613μmol/g when the weight proportion of Bi2S3 to CdS was 15%,which was about three times as large as that of CdS or two times of that of Bi2S3. | Xin Li Juntao Chen Huiling Li Jingtian Li Yitao Xu Yingju Liu Jiarong Zhou | 2011 | Journal of Natural Gas Chemistry2011，20，4： | 11 |
| 9 | Effects of biological soil crusts on water infiltration and evaporation Yanchi Ningxia, Maowusu Desert, China显示文摘Biological soil crusts serve as a vanguard for improving the ecological environment in arid,semi-arid desertification areas.It is a good indicator of the level of improvement which the local ecological environment is undertaking.In desert areas,water condition is a key factor of improving the ecological environment.As a first layer protection,biological crusts play an important role in local vegetation succession due to their abilities to conserve and maintain moisture.Using Maowusu desert in Yanchi of Ningxia province as an example,after three years of research,this paper chooses three kinds of biological crusts including lichen,moss and cyanobacterial which are under the cover of Artemisia ordosica as research objects.The results of this study indicate that,the closer biological crusts are to Artemisia ordosica vegetation,the thicker they become.In the same position of Artemisia ordosica vegetation,the thickness of moss crusts is the highest,followed by lichen crusts,and the thickness of cyanobacterial crusts is the lowest.Biological soil crusts coverage protects the natural water content of soil layers from0 to 5 cm.Also,it effects falling water to infiltrate deeper,and cannot prevent the surface water content from evaporating effectively.The effect of biological crusts blocking water infiltration decreases with the increase of rainfall.At the same rainfall level,moss crusts provide the strongest water infiltration blockage,followed by lichen crusts and cyanobacterial crusts.With the increase of rainfall,the depth of water infiltration increases.At the same rainfall level,the relationship of water infiltration depth is as follows:cyanobacterial crusts > lichen crusts > moss crusts.With the increase of biological crusts thickness,they blocking water infiltration capacity is stronger,and the depth of water infiltration is smaller.Analysis on the characteristic of simulated rainfall process on biological crusts shows that sandy land can be fixed by applying appropriate artificial biological crusts to build a sustainable forest protection system and to create a stable ecosystem in desertification area. | Bai Li Jiarong Gao Xiuru Wang Lan Ma Qiang Cui Maik Vest | 2016 | International Journal of Sediment Research2016，31，4： | 10 |
| 10 | Solidification Simulation of Investment Castings of Single Crystal Hollow Turbine Blade显示文摘The three-dimensional solidification simulation of the investment castings of single crystal hollow turbine blade at the withdrawal rates of 2 mm/min, 4.5 mm/min and 7 mm/min has been performed with the finite element thermal analysis. The calculated results are in accordance with the experimental ones. The results show that with the increase of withdrawal rate the concave curvature of the liquidus isotherm is larger and larger, and the temperature gradients of the blades increase. No effects of withdrawal rate on the distribution of the temperature gradients of the starter and helical grain selector of the blades are observed at withdrawal rates of 2 mm/min, 4.5 mm/min and 7 mm/min. The relatively high temperature gradient between 500℃/cm and 1000℃/cm in the starter and helical grain selector is obtained at three withdrawal rates. | Jiarong LI, Shizhong LIU, Hailong YUAN and Zhengang ZHONGNational Key Laboratory of Advanced High Temperature Structural Materials, Beijing Institute of Aeronautical Materials, Beijing 100095, China | 2003 | Journal of Materials Science & Technology2003，19，6： | 9 |

| 17 | Electrochemical synthesis of ammonia in molten salts显示文摘Ammonia is important feedstock for both fertilizer production and carbon-free liquid fuel.Many techniques for ammonia formation have been developed,hoping to replace the industrial energy-intensive Haber-Bosch route.Electrochemical synthesis of ammonia in molten salts is one promising alternative method due to the strong solubility of N3- ions,a wide potential window of molten salt electrolytes and tunable electrode reactions.Generally,electrochemical synthesis of ammonia in molten salts begins with the electro-cleavage of N2/hydrogen sources on electrode surfaces,followed by diffusion of N3^-/H^+-containing ions towards each other for NH3 formation.Therefore,the hydrogen sources and molten salt composition will greatly affect the reactions on electrodes and ions diffusion in electrolytes,being critical factors determining the faradaic efficiency and formation rate for ammonia synthesis.This report summarizes the selection criteria for hydrogen sources,the reaction characteristics in various molten salt systems,and the preliminary explorations on the scaling-up synthesis of ammonia in molten salt.The formation rate and faradaic efficiency for ammonia synthesis are discussed in detail based on different hydrogen sources,various molten salt systems,changed electrolysis conditions as well as diverse catalysts.Electrochemical synthesis of ammonia might be further enhanced by optimizing the molten salt composition,using electrocatalysts with well-defined composition and microstructure,and innovation of novel reaction mechanism. | Jiarong Yang Wei Weng Wei Xiao | 2020 | Journal of Energy Chemistry2020，29，4： | 5 |
| 18 | Preheating Characteristics of Datong Coal in O2/CO2 and Air Atmospheres显示文摘Experimental studies were carried out to find the difference of preheating characteristics of Datong coal in O_2/CO_2 and air atmospheres by a circulating fluidized bed. It is found that pulverized coal could be both steadily preheated to above 800°C in the two different atmospheres, but the temperature distribution was more uniform along the riser in O_2/CO_2 atmosphere. During the preheating, the content of CO in the flue gas can reach 12.32% under the O_2/CO_2 atmosphere, far higher than that in air(5.94%). Simultaneously, the conversion rate of fixed carbon was higher in O_2/CO_2 atmosphere compared with that in air. It can be inferred the higher oxygen concentration and higher partial pressure of CO_2 have greatly accelerated the gasification reaction. The BET analysis indicated a number of large pores were transformed into micropores during the preheating progress, and the major contributors for overall pore volume of chars and specific surface area are the micro-pores and the mesopores with diameter ranging from 2 nm to 10 nm. The inner pore structure was more developed in O_2/CO_2 atmosphere. | ZHU Jianguo MA Hongzhou LIU Dianbin LI Jiarong | 2018 | Journal of Thermal Science2018，27，4： | 5 |

| 20 | Robust reliable guaranteed cost control for uncertain singular systems with time-delay显示文摘The robust reliable guaranteed cost control for uncertain singular delay systems with actuator failures and a given quadratic cost function is studied. The system under consideration involves constant time-delay and norm-bounded parameter uncertainties. The purpose is to design state feedback controllers which can tolerate actuator failure, such that the closed-loop system is stable, and the specified cost function has an upper bound for all admissible uncertainties. The sufficient conditions for the solvability of this problem are obtained by a linear matrix inequality (LMI) method. Furthermore, a numerical example is given to demonstrate the applicability of the proposed approach. | Qixun Lan Yuxiao Liu Huawei Niu Jiarong Liang | 2010 | Journal of Systems Engineering and Electronics2010，21，1： | 4 |
