| 1 | Structure and coalbed methane occurrence in tectonically deformed coals显示文摘Research on structure of tectonically deformed coals(TDC) is a key issue in coal and gas outburst prevention and coalbed methane(CBM) exploitation.This paper presents a summary on the research progress in TDC's structural-genetic classification,tectonic strain influence on coal microstructure,coal porosity system,coal chemical structure and constituents,and their relationship with the excess coalbed methane.Previous studies suggested that tectonic deformation had significant influence on coal microstructure,coal super microstructure,and even chemical macromolecular structure.The main mechanisms of coal deformation are the tectonic stress degradation and polycondensation metamorphism(dynamical metamorphism).Besides,under different deformation mechanisms,the ultra-and micro-structure and chemical constituents of TDC presented distinct characteristics.Based on these achievements,we propose one possible evolutionary trend of TDC with different deformation mechanisms,and suggest that the coal and gas outburst in the TDC,especially in the mylonitic coals,may be not only controlled by geological structure,but also influenced by the tectonic stress degradation of ductile deformation.Therefore,further study on TDC should be focused on the controlling mechanism of deformation on structure and composition of coal,generation conditions and occurrence state of excess coalbed methane from deformation mechanism of coal. | HOU QuanLin LI HuiJun FAN JunJia JU YiWen WANG TianKai LI XiaoShi WU YuDong | 2012 | Science China Earth Sciences2012，55，11： | 49 |
| 2 | Management of cytokine release syndrome related to CAR-T cell therapy显示文摘Chimeric antigen receptor T (CAR-T) cell therapy is a novel cellular immunotherapy that is widely used to treat hematological malignancies, including acute leukemia, lymphoma, and multiple myeloma. Despite its remarkable clinical effects, this therapy has side effects that cannot be underestimated. Cytokine release syndrome (CRS) is one of the most clinically important and potentially life-threatening toxicities. This syndrome is a systemic immune storm that involves the mass cytokines releasing by activated immune cells. This phenomenon causes multisystem damages and sometimes even death. In this study, we reported the management of a patient with recurrent and refractory multiple myeloma and three patients with acute lymphocytic leukemia who suffered CRS during CAR-T treatment. The early application of tocilizumab, an anti-IL-6 receptor antibody, according to toxicity grading and clinical manifestation is recommended especially for patients who suffer continuous hyperpyrexia, hypotensive shock, acute respiratory failure, and whose CRS toxicities deteriorated rapidly. Moreover, low doses of dexamethasone (5-10 mg/day) were used for refractory CRS not responding to tocilizumab. The effective management of the toxicities associated with CRS will bring additional survival opportunities and improve the quality of life for patients with cancer. | Hongli Chen Fangxia Wang Pengyu Zhang Yilin Zhang Yinxia Chen Xiaohu Fan Xingmei Cao Jie Liu Yun Yang Baiyan Wang Bo Lei Liufang Gu Ju Bai Lili Wei Ruili Zhang Qiuchuan Zhuang Wanggang Zhang Wanhong Zhao Aili He | 2019 | Frontiers of Medicine2019，13，5： | 21 |

| 4 | Effect of L-NAME on nitric oxide and gastrointestinal motility alterations in cirrhotic rats显示文摘AIM: To invsstigare the effect of L-NAME on nitric oxide andgastriubtestubal motility alterations in cirrhotic ratsMETHODS: Rats with cirrhosis induced by carbontetrachloride were randomly divided into two groups, one( n= 13) receiving 0. 5 mg@ kg-1 per clay of NG-nitro-L-argininemethyl ester (L-NAME), a nitric oxide synthase inhibitor,for 10 days, whereas the other group ( n = 13) and control( n = 10) rats were administrated the same volume of 9 g@ L-1saline.Half gastric emptying time and 2 h residual rate weremeasured by SPECT, using 99m Tc-DTPA-labeled bariumsuifate as test meal. Gastrointestinal transition time wasrecorded simultaneously. Serum concentration of nitrcoxide (NO) was determined by the kinetic cadmiunreduction and colorimetric methods. ImmunohistochemicalSABC method was used to observe the expression anddistribution of three types of nitric oxide synthase (NOS)isoforms in the mt gastrointestinal tract. Western blot wasused to detect expression of gastrointestinal NOS isoforms.RESULTS: Half gastric emptying time and trans-gastrointestinal time were significantly prolonged( 124.0 ± 26.4min; 33.7± 8.9min;72.1 ± 15.3 min; P<0.01), (12.4±0.5h; 9.5±0.3 h; 8.2±0.8 h; P<0.01), 2h residual rate wasraised in cirrhotic rots than in controls and cirrhotic ratstreated with L-NAME(54.9± 7.6 % ,13.7 ± 3.2 %, 34.9± 10.3%, P< 0.01). Serum concentration of NO was significantlyincreased in cirrhotic rots than in the other groups (8.20 ± 2.48)μmol@L-1, (5.94± 1.07) μmol@L-1 ,and control (5.66± 1.60) tμmol@L-1, P< 0.01. NOS staining intensities which weremainly located in the gastrointestinal tissues were markedlylower in cirrhotic rats than in the controls and cirrhotic ratsafter treated with L- NAME.CONCLUSION: Gastrointestinal motility was remarkablyinhibited in cirrhotic rats, which could he alleviated by L-NAME. Nitric oxide may play an important role in theinhibition of gastrointestinal motility in cirrhotic rats. | Xin Wang Zong-You Zhang Mei Lan Ji-Yan Miao Xue-Gang Guo Yong-Quan Shi Yan-Qiu Zhao Jie Ding Kai-Cun Wu Dai-Ming Fan,Institute of Digestive disease,Xijing Hospital,Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China Yue-Xia Zhong,Emergency Department,Tangdu Hospital,Fourth Military Medical University,Xi’an 710038,Shaanxi Province,China Ju Lu,Class EE 87,Department of Electronic Engineering,Tsinghua University,Beijing 100084,China Bo-Rong Pan,Oncology Center,Xijing Hospital,Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China | 2002 | World Journal of Gastroenterology2002，8，2： | 19 |
| 5 | ENHANCED OIL RECOVERY BY FLOODING WITH HYDROPHILIC NANOPARTICLES显示文摘In this paper, the mechanism of enhanced oil recovery using lipophobic and hydrophilic polysilicon (LHP) nanoparticles ranging in size from 10 to 500 nm for changing the wettability of porous media was analysed theoretically. A one-dimensional two-phase mathematical model considering the migration and adsorption of LHP and wettability change in reservoir rock was proposed, and a simulator was developed to quantitatively predict the changes in relative and ef- fective permeability of the oil and water phases and the oil recovery in sandstone after water driving. Numerical simula- tions were conducted to study the distribution of the particle concentration, the reduction in porosity and absolute per- meability, the LHP volume retention on pore walls and in pore throats along a dimensionless distance, and oil production performance. In conclusion, oil recovery can obviously be improved by flooding with hydrophilic nanometer powders though permeability declines for the retention of nanoparticles in porous media. It is suggested that an LHP concentration ranging from 0.02 to 0.03 is preferable to enhance oil recovery. | Binshan Ju Tailiang Fan Mingxue Ma | 2006 | China Particuology2006，4，1： | 16 |

| 7 | Land subsidence monitoring by D-InSAR technique显示文摘Nowadays, the researches of using Differential Interferometric Synthetic Aperture Radar (D-InSAR) tech- nique to monitor the land subsidence are mainly on how to qualitatively analyze the subsidence areas and values, but the analysis of subsidence process and mechanism are insufficient. In order to resolve these problems, 6 scenes of ERS1/2 images captured during 1995 and 2000 in a certain place of Jiangsu province were selected to obtain the subsidence and velocities in three time segments by ''two-pass'' D- InSAR method. Then the relationships among distributions of pumping wells, exploitation quantity of groundwater, and confined water levels were studied and the subsidence mechanism was systematically analyzed. The results show that using D-InSAR technique to monitor the deformation of large area can obtain high accuracies, the disadvantages of classical observation methods can be remedied and there is a linear relationship among the velocities of land subsidence, the water level and the exploitation quantity. | Fan Hongdong Deng Kazhong Ju Chengyu Zhu Chuanguang Xue Jiqun China | 2011 | Mining Science and Technology2011，21，6： | 15 |

| 9 | Comparison of coalbed gas generation between Huaibei-Huainan coalfields and Qinshui coal basin based on the tectono-thermal modeling显示文摘The geothermal history and the tectonic subsidence history of the Huaibei-Huainan coalfields were reconstructed by using the vitrinite reflectance data, and their correlative restriction on coalbed gas generation of Huaibei-Huainan coalfields and Qinshui coal basin was discussed. The burial, thermal, and maturity histories of are similar between Huaibei coalfield and Huainan coalfield, obviously different from those of Qinshui coal basin. Based on the tectono-thermal evolution characters of Huaibei-Huainan coalfields and Qinshui basin, the process of coalbed gas generation can be divided into three stages: (1) During Early Mesozoic, both in Huaibei-Huainan and Qinshui, the buried depth of Permian coal seams increased rapidly, which resulted in strong metamorphism and high burial temperature of coal seams. At this stage, the coal rank was mainly fat coal, and locally reached coking coal. These created an environment favoring the generation of thermogenic gas. (2) From Late Jurassic to Cretaceous, in the areas of Huaibei-Huainan, the strata suffered from erosion and the crust became thinning, and the Permian coal-bearing strata were uplifted to surface. At this stage, the thermogenic gas mostly escaped. Conversely, in Qinshui basin, the cover strata of coal seams kept intact during this stage, and the thermogenic gas were mostly preserved. Furthermore, with the interaction of magmatism, the burial temperature of coal seams reached higher peak value, and it was suitable for the secondary generation of thermogenic gas. (3) From Paleogene onward, in area of Huainan-Huaibei, the maturity of coal and burial temperature were propitious to the generation of secondary biogenic gases. However, in Qinshui basin, the maturity of coal went against genesis of second biogenic gas or thermogenic gas. By comparison, Huaibei-Huainan coalfields are dominated by thermogenic gas with a significant biogenic gas and hydrodynamic overprint, whereas Qinshui basin is dominated mainly by thermogenic gas. | WU YuDong JU YiWen HOU QuanLin HU ShengBiao PAN JieNan FAN JunJia | 2011 | Science China Earth Sciences2011，54，7： | 13 |
| 10 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 11 | SIMULATION OF TANK SLOSHING BASED ON OPENFOAM AND COUPLING WITH SHIP MOTIONS IN TIME DOMAIN显示文摘Tank sloshing in ship cargo is excited by ship motions, which induces impact load on tank wall and then affects the ship motion. Wave forces acting on ship hull and the retardation function are solved by using three-dimensional frequency domain theory and an impulse response function method based on the potential flow theory, and global ship motion is examined coupling with nonlinear tank sloshing which is simulated by viscous flow theory. Based on the open source Computational Fluid Dynamics (CFD) development platform Open Field Operation and Manipulation (OpenFOAM), numerical calculation of ship motion coupled with tank sloshing is achieved and the corresponding numerical simulation and validation are carried out. With this method, the interactions of wave, ship body and tank sloshing are completely taken into consideration. This method has quite high efficiency for it takes advantage of potential flow theory for outer flow field and viscous flow theory for inside tank sloshing respectively. The numerical and experimental results of the ship motion agree well with each other. | LI Yu-long ZHU Ren-chuan MIAO Guo-ping FAN Ju | 2012 | Journal of Hydrodynamics2012，24，3： | 11 |
| 12 | Protective effects of Batroxobin on spinal cord injury in rats显示文摘Expansion of the secondary injury following primary spinal cord injury is a major pathological event that increases destruction in the spinal cord, so measures to reduce secondary injury are needed. Our previous study demonstrated that, at the front of the expanding secondary injury in the spinal cord, there is an ischemic area in which many neurons can still be rescued. Therefore, enhancement of blood circulation in the cord may be helpful, and indeed, we found that a traditional Chinese medicine, shu-xue-tong, efficiently reduces the secondary injury. The aim of the present study was to investigate the effect of reducing fibrinogen with Batroxobin, a drug widely used clinically for ischemia, in rats with spinal cord contusion. We found that both 2 and 4 Batroxobin units (BU)/kg efficiently decreased the plasma fibrinogen, and 2 BU/kg significantly increased spinal blood flow, enhanced neuronal survival, mitigated astrocyte and microglia activation, and improved locomotor recovery. However, 4 BU/kg had no effect on the secondary spinal cord injury. These data suggest that Batroxobin has multiple beneficial effects on spinal cord injury, indicating a potential clinical application. | Hong Fan Xia Liu Hai-Bin Tang Peng Xiao Ya-Zhou Wang Gong Ju | 2013 | Neuroscience Bulletin2013，29，4： | 11 |

| 14 | Differences between dynamics factors for interannual and decadal variations of rainfall over the Yangtze River valley during flood seasons显示文摘The rainfall over the Yangtze River val- ley during flood seasons (June to July) shows both interannual and decadal variations. The rainfall has been increasing since 1990, showing a decadal sig- nal. The variations of rainfall are influenced by the multi-scale interactions in the atmosphere-ocean coupled climate system. The rainfall, SST, and cir- culation are analyzed with the Chinese 160 station data, and other observational/reanalysis data, re- spectively. The separation between the interannual and decadal variations is carried out. The key areas affecting the Yangtze rainfall are the western Pacific warm pool on the interannual time scale and the EINO3 area on the decadal time scale, respectively. The circulation anomaly associated with the interan- nual variation occurs in the upper troposphere whereas that associated with the decadal variation appears in the lower troposphere. | PING Fan LUO Zhexian JU Jianhua | 2006 | Chinese Science Bulletin2006，51，8： | 9 |
| 15 | Response of Macromolecular Structure to Deformation in Tectonically Deformed Coal显示文摘有不同 deformational 机制和不同 deformational 紧张的构造地使变形的煤(TDC ) 的结构的进化通过 31 上的分析不同变形等级取样的 X 光检查衍射(XRD ) 深入地被调查(Ro,最大:0.7%3.1%) 从 Huaibei 煤田镇定。结果显示在有变态和变丑增加的可锻、易碎的 deformational 煤之间有不同进化特征。随变态的增加,在一方面,原子飞机间距( d002 )在步速度正在减少,叠 BSU 层( Lc )起初正在增加然后减少,但是 BSU 层( La )和 La/Lc 的比率的延期开始正在减少然后增加。为易碎的 deformational 煤,当 deformational 紧张正在增加时,在另一方面, d002 开始正在增加然后减少,它在降低中间或高中间的变态等级下面引起 Lc 和 La 的变化的倒置。在可锻的 deformational 煤,相反, d002 开始减少了然后增加,并且 Lc 的价值随 deformational 的增加减少了紧张。但是 La 的价值在降低中间的变态等级下面增加了并且起初增加了然后在高中间的变态等级下面减少了。我们断定 TDC macromolecular 结构的降级和 polycondensation 能显然在可锻的 deformational 过程期间被影响,因为统一脱臼的增加和累积也许把压力转变成紧张精力。同时,易碎的变丑能把压力转变成部分热能,并且也支持变态和降级。变丑比对可锻、易碎的 deformational 煤的微分进化的变态更重要,这能被结束。 | LI Xiaoshi JU Yiwen HOU Quanlin FAN Junjia | 2013 | Acta Geologica Sinica(English Edition)2013，87，1： | 8 |
| 16 | Effect of Calcium Oxide Additive on the Performance of Iron Oxide Sorbent for High-Temperature Coal Gas Desulfurization显示文摘The effect of calcium oxide additive in iron oxide sorbent for hot gas desulfurization was investigated by XRD and TPR techniques.XRD characterization showed that CaO was highly dispersed after the calcination of sorbents.Calcium sulfate formed in the desulfurization was decomposed and regenerated to CaO by reacting with CO before the next sulfidation process.Calcium participated in every sulfidation/regeneration cycle and contributed to the enhancement of sulfur capacity.The TPR results showed that the reduction temperature of the sorbent increased with the increase of the content of calcium.Calcium played a role of retarding reduction.Therefore,the addition of calcium oxide additive will benefit the utilization of iron oxide sorbent in strongly reducing atmospheres. | Huiling Fan Kechang Xie Ju Shangguan Fang Shen Chunhu Li | 2007 | Journal of Natural Gas Chemistry2007，16，4： | 7 |
| 17 | Successful embryo transfer in Tianzhu white yak using standard protocol显示文摘The present study was carried out to investigate the efficiency of superovulation, oestrus synchroni-zation, and embryo recovery in Tianzhu white yaks and also to confirm the pregnancy rate of black yaks, to which embryos collected from white yaks were transplanted. Forty-seven yaks were selected from different experiment groups, including 10 Tianzhu white female yaks (donor, group A) and 37 black female yaks (recipient, groups B and C). Superovulation of the donor was induced by the application procedure of CIDR-B + FSH + PG. Oestrus synchronization of recipients was induced using two meth-ods: group B was given the same treatment as group A, except that the follicle-stimulating hormone (FSH) injection was not administered, whereas group C was injected with cloprostenol only once when corpus luteum (corpora lutea) was (were) palpated. The results showed that the oestrous rates in group A were higher (80%) than those in group B (60%) and group C (44.5%). As for the efficiency of su-perovulation, it was indicated that the mean numbers (±SD) of total corpora lutea, follicles, viable (transferable), and degenerated embryos were 4.75 ± 2.19, 1.13 ± 0.83, 2.50 ± 1.31, and 1.38 ± 0.92, re-spectively. The mean embryo recovery rates were 55.6%. All together, 18 viable embryos of Tianzhu white yak were obtained and 12 of them were transplanted to 10 recipients. The pregnancy rate was 50% and the delivery rate was 40%. | YU SiJiu JU XiangHong WANG LiBin FAN JiangFeng | 2007 | Science China(Life Sciences)2007，50，5： | 7 |
| 18 | Numerical simulation of rolling for 3-D ship with forward speed and nonlinear damping analysis显示文摘Strongly nonlinear characteristics of ship roll owing to viscous effect can be usually observed. To describe the nonlinear roll behavior, the CFD method has been frequently employed with obvious advantages compared with the traditional semi-empirical formula method in estimating the roll damping. Numerical simulations of free decay and forced rolling at various forward speeds and amplitudes for a 3-D ship hull are conducted in the present research to predict ship roll damping, in which a RANS solver is employed and a dynamic mesh technique is adopted and discussed in detail. Numerical results, including nonlinear flow characters around ships, rolling decay curves and damping coefficients, show that they are all in good agreement with available experimental data. The linear and nonlinear damping coefficients are estimated and analyzed by fitting with exponential functions for various rolling amplitudes, frequencies and speeds in the free decay simulations, and the damping coefficients are obtained by a polynomial fitting in the forced roll simulations. It is indicated that the damping coefficients increase with increasing rolling angle amplitude and velocity. It is also emphasized that the effect of forward speed is significant to roll damping and the nonlinear damping decreases with increasing velocity. | YANG Chun-lei ZHU Ren-chuan MIAO Guo-ping FAN Ju | 2013 | Journal of Hydrodynamics2013，25，1： | 6 |
| 19 | The Medium Energy X-ray telescope (ME) onboard the Insight-HXMT astronomy satellite显示文摘The Medium Energy X-ray telescope(ME) is one of the three main telescopes on board the Insight hard X-ray modulation telescope(Insight-HXMT) astronomy satellite. ME contains 1728 pixels of Si-PIN detectors sensitive in 5-30 ke V with a total geometrical area of 952 cm^2. The application specific integrated circuit(ASIC) chip, VA32TA6, is used to achieve low power consumption and low readout noise. The collimators define three kinds of field of views(FOVs) for the telescope, 1°×4°, 4°×4°,and blocked ones. Combination of such FOVs can be used to estimate the in-orbit X-ray and particle background components.The energy resolution of ME is ~3 ke V at 17.8 ke V(FWHM) and the time resolution is 255 μs. In this paper, we introduce the design and performance of ME. | XueLei Cao WeiChun Jiang Bin Meng WanChang Zhang Tao Luo Sheng Yang ChunLei Zhang YuDong Gu Liang Sun XiaoJing Liu JiaWei Yang Xian Li Ying Tan ShaoZhen Liu YuanYuan Du FangJun Lu YuPeng Xu Ju Guan ShuangNan Zhang HuanYu Wang TiPei Li ChengMo Zhang XiangYang Wen JinLu Qu LiMing Song XiaoBo Li MingYu Ge YuPeng Zhou ShaoLin Xiong Shu Zhang YongJie Zhang ZeHao Cheng Fei Zhang MaoShun Li XiaoHua Liang Min Gao EnBo Yang XiaoHang Liu HongWei Liu YiJung Yang Fan Zhang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 5 |
| 20 | Hedgehog signaling in gastrointestinal carcinogenesis and the gastrointestinal tumor microenvironment显示文摘The Hedgehog(HH) signaling pathway plays important roles in gastrointestinal carcinogenesis and the gastrointestinal tumor microenvironment(TME). Aberrant HH signaling activation may accelerate the growth of gastrointestinal tumors and lead to tumor immune tolerance and drug resistance.The interaction between HH signaling and the TME is intimately involved in these processes, for example, tumor growth, tumor immune tolerance, inflammation, and drug resistance. Evidence indicates that inflammatory factors in the TME, such as interleukin 6(IL-6) and interferon-g(IFN-g), macrophages, and T cell-dependent immune responses, play a vital role in tumor growth by affecting the HH signaling pathway. Moreover, inhibition of proliferating cancer-associated fibroblasts(CAFs) and inflammatory factors can normalize the TME by suppressing HH signaling. Furthermore, aberrant HH signaling activation is favorable to both the proliferation of cancer stem cells(CSCs) and the drug resistance of gastrointestinal tumors. This review discusses the current understanding of the role and mechanism of aberrant HH signaling activation in gastrointestinal carcinogenesis, the gastrointestinal TME,tumor immune tolerance and drug resistance and highlights the underlying therapeutic opportunities. | Jinghui Zhang Jiajun Fan Xian Zeng Mingming Nie Jingyun Luan Yichen Wang Dianwen Ju Kai Yin | 2021 | Acta Pharmaceutica Sinica B2021，11，3： | 5 |
