| 3 | Biomolecular basis of the role of diabetes mellitus in osteoporosis and bone fractures显示文摘Osteoporosis has become a serious health problem throughout the world which is associated with an increased risk of bone fractures and mortality among the people of middle to old ages.Diabetes is also a major health problem among the people of all age ranges and the sufferers due to this abnormality increasing day by day.The aim of this review is to summarize the possible mechanisms through which diabetes may induce osteoporosis.Diabetes mellitus generally exerts its effect on different parts of the body including bone cells specially the osteoblast and osteoclast,muscles,retina of the eyes,adipose tissue,endocrine system specially parathyroid hormone(PTH) and estrogen,cytokines,nervous system and digestive system.Diabetes negatively regulates osteoblast differentiation and function while positively regulates osteoclast differentiation and function through the regulation of different intermediate factors and thereby decreases bone formation while increases bone resorption.Some factors such as diabetic neuropathy,reactive oxygen species,Vitamin D,PTH have their effects on muscle cells.Diabetes decreases the muscle strength through regulating these factors in various ways and ultimately increases the risk of fall that may cause bone fractures. | Bipradas Roy | 2013 | World Journal of Diabetes2013,4,4: | 41 |
| 4 | Molecular mechanisms of liver ischemia reperfusion injury:Insights from transgenic knockout models显示文摘Ischemia reperfusion injury is a major obstacle in liver resection and liver transplantation surgery.Understanding the mechanisms of liver ischemia reperfusion injury(IRI) and developing strategies to counteract this injury will therefore reduce acute complications in hepatic resection and transplantation,as well as expanding the potential pool of usable donor grafts.The initial liver injury is initiated by reactive oxygen species which cause direct cellular injury and also activate a cascade of molecular mediators leading to microvascular changes,increased apoptosis and acute inflammatory changes with increased hepatocyte necrosis.Some adaptive pathways are activated during reperfusion that reduce the reperfusion injury.IRI involves a complex interplay between neutrophils,natural killer T-cells cells,CD4+ T cell subtypes,cytokines,nitric oxide synthases,haem oxygenase-1,survival kinases such as the signal transducer and activator of transcription,Phosphatidylinositol 3-kinases/Akt and nuclear factor κβ pathways.Transgenic animals,particularly genetic knockout models,have become a powerful tool at elucidating mechanisms of liver ischaemia reperfusion injury and are complementary to pharmacological studies.Targeted disruption of the protein at the genetic level is more specific and maintained than pharmacological inhibitors or stimulants of the same protein.This article reviews the evidence from knockout models of liver IRI about the cellular and molecular mechanisms underlying liver IRI. | Gourab Datta Barry J Fuller Brian R Davidson | 2013 | World Journal of Gastroenterology2013,19,11: | 50 |

| 6 | Effects of AT1 receptor antagonist,Iosartan,on rat hepatic fibrosis induced by CCl_4显示文摘AIM To investigate effect of losartan,an AT1receptor antagonist,on hepatic fibrosis induced byCCl;and to determine whether or not AT1receptors are expressed on hepatic stellate cells,METHODS AND RESULTS Fifty male Sprague-Dawley rats,weighing(180±20)g,wererandomized into five groups(control group,modelgroup,and three losartan treated groups),inwhich all rats were given the subcutaneousinjection of 40% CCl4(every 3 days for 6 weeks)except for rats of control group.Rats of losartan-treated groups were treated with losartan(20 mg/kg,10 mg/kg,5 mg/kg,daily gavage),After 6weeks liver tissue and serum samples of all ratswere examined.Serum hyaluronic acid(HA),procollagen typeⅢ(PCⅢ)were detected byradioimmunoassays,van Giesion collagen stainingwas used to evaluate the extracellular matrix of ratswith liver fibrosis.The expression of AT1receptors,transforming growth factor-beta(TGF-β),and alpha-smooth muscle actin(a-SMA)inliver tissue were determined byimmunohistochemical techniques.Compared withmodel group,serum ALT and AST of losartan-treated groups were significantly reduced(t=4.20,P<0.01 and t=4.57,P<0.01).Serum HAand PCⅢalso had significant differences(t=3.53,P<0.01 and t=2.20,P<0.05).Thedegree of fibrosis was improved by losartan and correlated with the expressions of AT1 receptors,TGF-β,and α-SMA in liver tissue.CONCLUSION AT1 receptor antagonist,losartan,could limit the progression of the hepatic fibrosisinduced by CCl4.The mechanism may be related tothe decrease in the expression of AT1 receptorsand TGF-β,ameliorating the injury of hepatocytes;activation of local renin-angiotensin system mightrelate to hepatic fibrosis;and during progressionof fibrosis,activated hepatic stellate cells mightexpress AT1 receptors. | Hong Shan Wei Ding Guo Li Han Ming Lu Yu Tao Zhan Zhi Rong Wang Xin Huang Jing Zhang Ji Lin Cheng Qin Fang Xu Department of Gastroenterology,Xinhua Hospital,Shanghai Second Medical University,Shanghai 200092,China | 2000 | World Journal of Gastroenterology2000,6,4: | 42 |
| 7 | Androgen receptor: structure, role in prostate cancer and drug discovery显示文摘Androgens and androgen receptors (AR) play a pivotal role in expression of the male phenotype. Several diseases, such as androgen insensitivity syndrome (AIS) and prostate cancer, are associated with alterations in AR functions. Indeed, androgen blockade by drugs that prevent the production of androgens and/or block the action of the AR inhibits prostate cancer growth. However, resistance to these drugs often occurs after 2-3 years as the patients develop castration-resistant prostate cancer (CRPC). In CRPC, a functional AR remains a key regulator. Early studies focused on the functional domains of the AR and its crucial role in the pathology. The elucidation of the structures of the AR DNA binding domain (DBD) and ligand binding domain (LBD) provides a new framework for understanding the functions of this receptor and leads to the development of rational drug design for the treatment of prostate cancer. An overview of androgen receptor structure and activity, its actions in prostate cancer, and how structural information and high-throughput screening have been or can be used for drug discovery are provided herein. | MH Eileen TAN Jun LI H Eric XU Karsten MELCHER Eu-leong YONG | 2015 | Acta Pharmacologica Sinica2015,36,1: | 39 |
| 8 | 儿童肺功能系列指南(五):支气管舒张试验显示文摘支气管舒张试验(bronchodilation test,BDT)又称呼吸道可逆性试验(airway reversibility test),是指对于已有气流阻塞的患者,应用一定剂量的支气管舒张剂[通常用速效β2受体激动剂(short acting beta 2 receptor agonist,SABA)]后重复测定肺功能,以评价气流阻塞可逆程度的试验,是应用于支气管哮喘等疾病重要的诊断和鉴别诊断方法。支气管平滑肌痉挛是引起气流阻塞的重要原因之一,吸入性SABA可迅速缓解支气管痉挛和改善气流阻塞,BDT即应用这一原理来了解气流阻塞可逆性的程度。 | 无 | 2017 | 中华实用儿科临床杂志2017,32,1: | 36 |
| 9 | Hyaluronic acid fragments evoke Kupffer cells via TLR4 signaling pathway显示文摘Kupffer cells, expressing toll-like receptor 4 (TLR4), play a central role in hepatic ischemia/reperfusion (I/R) injury. Hyaluronic acid (HA) fragments, degradative products of high-molecular-weight HA (HMW-HA), acquire the ability to activate immune cells under inflammatory conditions. Here we inves- tigated whether HA fragments could activate Kupffer cells and analyzed the underlying mechanism. Kupffer cells were isolated from wild-type mice (WT, C3H/HeN) and TLR4 mutant mice (C3H/HeJ) and HA fragments were produced by the methods of enzyme digestion and chromatography. Then Kupffer cells were stimulated by HA fragments or other control stimuli. The activation of Kupffer cells was estimated as the release of pro-inflammatory cytokines. The activation of p38 MAPK pathway of Kupffer cells was checked and blocking experiments were done as well. The results indicated that HA fragments acquired the ability to activate Kupffer cells in vitro, which was TLR4 dependent and not due to contamination of lipopolysaccharide. Experiments of p38 MAPK kinase inhibition by SB-203580 verified p38 MAPK was required in HA fragments induced Kupffer cells activation. This suggests that HA fragments, degradative products of one of the major glycosaminoglycans of the extracellular matrix, play critical roles in Kupffer cell activation mediated by TLR4 signaling pathway, which is, at least partially, de- pendent on p38 MAPK activation. | ZHANG JinXiang1, WANG Hui2, XIAO Qing3, LIANG HuiFang4, LI ZhuoYa4, JIANG ChunFang1, WU HeShui5 & ZHENG QiChang5 1 Department of Emergency Surgery, Union Hospital Affiliated to Huazhong University of Science and Technology, Wuhan 430022, China 2 Department of Medical Genetics, Tongji Medical College Affiliated to Huazhong University of Science and Technology, Wuhan 430030, China 3 Department of Ophthalmology, Union Hospital Affiliated to Huazhong University of Science and Technology, Wuhan 430022, China 4 Department of Medical Immunology, Tongji Medical College Affiliated to Huazhong University of Science and Technology, Wuhan 430030, China 5 Department of General Surgery, Union Hospital Affiliated to Huazhong University of Science and Technology, Wuhan 430022, China | 2009 | Science China(Life Sciences)2009,52,2: | 33 |
| 10 | 孕期维生素D水平与不良妊娠结局相关性研究进展显示文摘随着对维生素 D受体(vitamin D receptor, VDR)的认识,维生素D的非经典作用越来越受到学者们的广泛关注。越来越多的研究[1-2]表明,孕期血清维生素D的水平与包括早产、过期产、子痫前期及妊娠期糖尿病等在内的一系列不良妊娠结局密切相关。但如何定义维生素D缺乏学术界尚存争议,大多数学者认为维生素D缺乏即血清25(OH)D <20 ng/mL (50 nmol/L);25(OH)D <30 ng/mL (75 nmol/L)为不足。近年来,孕妇血清维生素D水平缺乏的流行现状及临床意义已成为研究的热点之一。本文就孕期维生素D水平缺乏的流行现状、孕妇维生素D水平与孕期长短、妊娠期糖尿病、子痫前期等不良妊娠结局的相关性进行阐述,为临床维生素D的预防性应用提供依据。 | 王丽萍 黄金 | 2015 | 实用医学杂志2015,31,20: | 31 |
| 11 | Colorectal cancer tumour markers and biomarkers:Recenttherapeutic advances显示文摘Colorectal cancer(CRC) is the second most commonly diagnosed cancer among females and third among males worldwide. It also contributes significantly to cancer-related deaths, despite the continuous progress in diagnostic and therapeutic methods. Biomarkers currently play an important role in the detection and treatment of patients with colorectal cancer. Risk stratification for screening might be augmented by finding new biomarkers which alone or as a complement of existing tests might recognize either the predisposition or early stage of the disease. Biomarkers have also the potential to change diagnostic and treatment algorithms by selecting the proper chemotherapeutic drugs across a broad spectrum of patients. There are attempts to personalise chemotherapy based on presence or absence of specific biomarkers. In this review, we update review published last year and describe our understanding of tumour markers and biomarkers role in CRC screening, diagnosis, treatment and follow-up. Goal of future research is to identify those biomarkers that could allow a non-invasive and cost-effective diagnosis, as well as to recognise the best prognostic panel and define the predictive biomarkers for available treatments. | Gustaw Lech Robert Słotwiński Maciej Słodkowski Ireneusz Wojciech Krasnodębski | 2016 | World Journal of Gastroenterology2016,22,5: | 33 |
| 12 | TLR4 signaling induced TLR2 expression in the process of mimic cerebral ischemia/reperfusion in vitro显示文摘Both TLR4 and TLR2 participated in the mediation of the inflammatory injury in the process of partial cerebral ischemia/reperfusion.However,it still remains unclear whether a crosstalk exists between TLR2 and TLR4 in ischemic cerebral damage.In the present study,we investigated the effect of TLR4 signaling on TLR2 expression during mimic cerebral I/R in vitro.BV-2 cells were cultured and treated with ischemia/reperfusion,then transfected with the plasmid pEGFP-H1/TLR4-siRNA,the plasmid pEGFP-H1/control sequence-siRNA and the blank plasmid,respectively.Interestingly,the expression of TLR2 and TLR4 mRNA and protein,NF-κB p65 mRNA and supernatant TNF-α level were significantly higher in ischemia/reperfusion treated cells than those lack of ischemia/reperfusion treatment,and as compared with those in ischemia/reperfusion treated cells without transfection,no significant differences about the above mentioned gene and protein expression were found in the blank plasmid tranfected cells and the plasmid pEGFP-H1/control sequence-siRNA transfected cells respectively,while the expression levels in the plasmid pEGFP-H1/TLR4-siRNA transfected cells were significantly lower.Additionally,in order to determine the effects of pyrrolidinediethyldithiocarbamate (PDTC),an NF-κB inhibitor,on the TLR4-induced TLR2 expression in BV-2 cells treated with ischemia/reperfusion,it was found that TLR4 and TLR2 mRNA expressions in PDTC pretreated cells were significantly lower in comparison with normal saline pretreated cells and non-pretreated cells.The data suggested that TLR2 activation,signaled by TLR4 and regulated by NF-κB,might be directly involved play an important role in ischemia/reperfusion induced brain damage. | SUN Peng1,ZHANG Qing2,HAN JiYuan1,TIAN Yuan3 & ZHANG JingHui3 1Department of Emergency,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan 430022,China 2Department of Anesthesia,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan 430022,China 3Department of General Surgery,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan 430022,China | 2010 | Science China(Life Sciences)2010,53,2: | 30 |
| 13 | Clinical Research on Alzheimer's Disease: Progress and Perspectives显示文摘Alzheimer's disease(AD), the most common type of dementia, is becoming a major challenge for global health and social care. However, the current understanding of AD pathogenesis is limited, and no early diagnosis and disease-modifying therapy are currently available. During the past year, significant progress has been made in clinical research on the diagnosis, prevention, and treatment of AD.In this review, we summarize the latest achievements,including diagnostic biomarkers, polygenic hazard score,amyloid and tau PET imaging, clinical trials targeting amyloid-beta(Ab), tau, and neurotransmitters, early intervention, and primary prevention and systemic intervention approaches, and provide novel perspectives for further efforts to understand and cure the disease. | Bin-Lu Sun Wei-Wei Li Chi Zhu Wang-Sheng Jin Fan Zeng Yu-Hui Liu Xian-Le Bu Jie Zhu Xiu-Qing Yao Yan-Jiang Wang | 2018 | Neuroscience Bulletin2018,34,6: | 29 |

| 15 | Clinicopathologic factors and molecular markers related to lymph node metastasis in early gastric cancer显示文摘AIM: To analyze predictive factors for lymph node metastasis in early gastric cancer.METHODS: We analyzed 1104 patients with early gastric cancer(EGC) who underwent a gastrectomy with lymph-node dissection from May 2003 through July 2011. The clinicopathologic factors and molecular markers were assessed as predictors for lymph node metastasis. Molecular markers such as microsatellite instability, human mut L homolog 1, p53, epidermal growth factor receptor(EGFR) and human epidermal growth factor receptor 2(HER2) were included. The χ2 test and logistic regression analysis were used to determine clinicopathologic parameters.RESULTS: Lymph node metastasis was observed in 104(9.4%) of 1104 patients. Among 104 cases of lymph node positive patients, 24 patients(3.8%) were mucosal cancers and 80 patients(16.7%) were submucosal. According to histologic evaluation, the number of lymph node metastasis found was 4(1.7%) for well differentiated tubular adenocarcinoma, 45(11.3%) for moderately differentiated tubular adenocarcinoma, 36(14.8%) for poorly differentiated tubular adenocarcinoma, and 19(8.4%) for signet ring cell carcinoma. Of 690 EGC cases, 77 cases(11.2%) showed EGFR overexpression. HER2 overexpression was present in 110 cases(27.1%) of 406 EGC patients. With multivariate analysis, female gender(OR = 2.281, P = 0.009), presence of lymphovascular invasion(OR = 10.950, P < 0.0001), diameter(≥ 20 mm, OR = 3.173, P = 0.01), and EGFR overexpression(OR = 2.185, P = 0.044) were independent risk factors for lymph node involvement.CONCLUSION: Female gender, tumor size, lymphovascular invasion and EGFR overexpression were predictive risk factors for lymph node metastasis in EGC. | Eun Hyo Jin Dong Ho Lee Sung-Ae Jung Ki-Nam Shim Ji Yeon Seo Nayoung Kim Cheol Min Shin Hyuk Yoon Hyun Chae Jung | 2015 | World Journal of Gastroenterology2015,21,2: | 30 |
| 16 | Correlation of human epidermal growth factor receptor 2 expression with clinicopathological characteristics and prognosis in gastric cancer显示文摘AIM:To investigate human epidermal growth factor receptor 2(HER2) gene amplification and protein expression in Chinese patients with resectable gastric cancer and the association with clinicopathological characteristics and survival.METHODS:One hundred and ninety-seven gastric cancer patients who underwent curative surgery procedures were enrolled into this study.HER2 gene amplification and protein expression were examined using fluorescence in-situ hybridization(FISH) and immunohistochemistry(IHC) analysis on formalin-fixed paraffinembedded gastric cancer samples from all patients.For scoring,Hofmann's HER2 gastric cancer scoring system was adopted.All cases showing IHC3+ or FISH positiv-ity were defined as HER2 positive.Patient clinicopathological data and survival information were collected.Finally,χ 2 statistical analysis was performed to analyze the HER2 positivity rate amongst the subgroups with different clinicopathological characteristics including;gender,age,tumor location,Lauren classification,differentiation,TNM staging,depth of invasion,lymph node metastases and distant metastasis.The probability of survival for different subgroups with different clinicopathological characteristics was calculated using the Kaplan-Meier method and survival curves plotted using log rank inspection.RESULTS:According to Hofmann's HER2 gastric cancer scoring criteria,31 cases(15.74%) were identified as HER2 gene amplified and 19 cases(9.64%) were scored as strongly positive for HER2 membrane staining(3+),25 cases(12.69%) were moderately positive(2+) and 153 cases(77.66%) were HER2 negative(0/1+).The concordance rate between IHC and FISH analyses was 88.83%(175/197).Thirty-six cases were defined as positive for HER2 gene amplification and/or protein expression,with 24 of these cases being eligible for Herceptin treatment according to United States recommendations,and 29 of these cases eligible according to EU recommendations.Highly consistent results were detected between IHC3+,IHC0/1 and FISH(73.68% and 95.42%),but low consistency was observed between IHC2+ and FISH(40.00%).The positivity rates in intestinal type and well-differentiated gastric cancer were higher than those in diffuse/mixed type and poorly-differentiated gastric cancer respectively(28.57% vs 13.43%,P = 0.0103;37.25% vs 11.64%,P < 0.0001),but were not correlated with gender,age,tumor location or TNM stage,depth of invasion,lymph node metastases and distant metastasis.In poorly-differentiated gastric cancer patients,those without lymph node metastasis showed a higher HER2 positivity rate than those with lymph node metastasis(26.47% vs 7.14%,P = 0.0021).This association was not present in thosepatients with well-differentiated gastric cancer(28.57% vs 43.33%,P = 0.2832).Within our patient cohort,26 cases were lost to follow-up.The median survival time for the remaining 171 patients was 18 mo.The median survival times of the HER2 positive and negative groups were 17 and 18.5 mo respectively.Overall survival was not significantly different between HER2-positive and negative groups(χ 2 = 0.9157,P = 0.3386),but in patients presenting well-differentiated tumors,the overall survival of the HER2-positive group was significantly worse than that of the HER2-negative group(P = 0.0123).In contrast,patients with poorly differentiated and diffuse/mixed subtype gastric cancers showed no significant differences in overall survival associated with HER2.Furthermore,the median survival time of the HER2 positive group did not show any statistically significant differences when compared to the subgroups of gender,age,tumor location,TNM classification,lymph node metastases and distant metastasis.CONCLUSION:Patients with intestinal type gastric cancer(GC),well-differentiated GC and poorly-differentiated GC without lymph node metastasis,may all represent suitable candidates for targeted therapy using Herceptin. | Chao He Xue-Yi Bian Xing-Zhi Ni Dan-Ping Shen Yan-Ying Shen Hua Liu Zhi-Yong Shen Qiang Liu | 2013 | World Journal of Gastroenterology2013,19,14: | 28 |
| 17 | Neural mechanism of gastric motility regulation by electroacupuncture at RN12 and BL21: A paraventricular hypothalamic nucleus-dorsal vagal complex-vagus nervegastric channel pathway显示文摘AIM: To study the neural mechanism by which electroacupuncture(EA) at RN12(Zhongwan) and BL21(Weishu) regulates gastric motility.METHODS: One hundred and forty-four adult Sprague Dawley rats were studied in four separate experiments. Intragastric pressure was measured using custommade rubber balloons, and extracellular neuron firing activity, which is sensitive to gastric distention in the dorsal vagal complex(DVC), was recorded by an electrophysiological technique. The expression levels of c-fos, motilin(MTL) and gastrin(GAS) in the paraventricular hypothalamic nucleus(PVN) were assayed by immunohistochemistry, and the expression levels of motilin receptor(MTL-R) and gastrin receptor(GAS-R) in both the PVN and the gastric antrum were assayed by western blotting.RESULTS: EA at RN12 + BL21(gastric Shu and Mu points), BL21(gastric Back-Shu point), RN12(gastric Front-Mu point), resulted in increased neuron-activating frequency in the DVC(2.08 ± 0.050, 1.17 ± 0.023, 1.55 ± 0.079 vs 0.75 ± 0.046, P < 0.001) compared with a model group. The expression of c-fos(36.24 ± 1.67, 29.41 ± 2.55, 31.79 ± 3.00 vs 5.73 ± 2.18, P < 0.001), MTL(22.48 ± 2.66, 20.76 ± 2.41, 19.17 ± 1.71 vs 11.68 ± 2.52, P < 0.001), GAS(24.99 ± 2.95, 21.69 ± 3.24, 23.03 ± 3.09 vs 12.53 ± 2.15, P < 0.001), MTL-R(1.39 ± 0.05, 1.22 ± 0.05, 1.17 ± 0.12 vs 0.84 ± 0.06, P < 0.001), and GAS-R(1.07 ± 0.07, 0.91 ± 0.06, 0.78 ± 0.05 vs 0.45 ± 0.04, P < 0.001) increased in the PVN after EA compared with the model group. The expression of MTL-R(1.46 ± 0.14, 1.26 ± 0.11, 0.99 ± 0.07 vs 0.65 ± 0.03, P < 0.001), and GAS-R(1.63 ± 0.11, 1.26 ± 0.16, 1.13 ± 0.02 vs 0.80 ± 0.11, P < 0.001) increased in the gastric antrum after EA compared with the model group. Damaging the PVN resulted in reduced intragastric pressure(13.67 ± 3.72 vs 4.27 ± 1.48, P < 0.001). These data demonstrate that the signals induced by EA stimulation of acupoints RN12 and BL21 are detectable in the DVC and the PVN, and increase the levels of gastrointestinal hormones and their receptors in the PVN and gastric antrum to regulate gastric motility. CONCLUSION: EA at RN12 and BL21 regulates gastric motility, which may be achieved through the PVN-DVCvagus-gastric neural pathway. | Hao Wang Wen-Jian Liu Guo-Ming Shen Meng-Ting Zhang Shun Huang Ying He | 2015 | World Journal of Gastroenterology2015,21,48: | 27 |

| 19 | CXC chemokines and chemokine receptors in gastric cancer: From basic findings towards therapeutic targeting显示文摘Gastric cancer is the fourth most common cancer,and the second-highest cause of cancer-related deaths worldwide.Despite extensive research to identify novel diagnostic and therapeutic agents,patients with advanced gastric cancer suffer from a poor quality of life and poor prognosis,and treatment is dependent mainly on conventional cytotoxic chemotherapy.To improve the quality of life and survival of gastric cancer patients,a better understanding of the underlying molecular pathologies,and their application towards the development of novel targeted therapies,is urgently needed.Chemokines are a group of small proteins associated with cytoskeletal rearrangements,the directional migration of several cell types during development and physiology,and the host immune response via interactions with G-protein coupled receptors.There is also growing evidence to suggest that chemokines not only play a role in the immune system,but are also involved in the development and progression of tumors.In gastric cancer,CXC chemokines and chemokine receptors regulate the trafficking of cells in and out of the tumor microenvironment.CXC chemokines and their receptors can also directly influence tumorigenesis by modulating tumor transformation,survival,growth,invasion and metastasis,as well as indirectly by regulating angiogenesis,and tumor-leukocyte interactions.In this review,we will focus on the roles of CXC chemokines and their receptors in the development,progression,and metastasis of gastric tumors,and discuss their therapeutic potential for gastric cancer. | Hyo Jin Lee Ik-Chan Song Hwan-Jung Yun Deog-Yeon Jo Samyong Kim | 2014 | World Journal of Gastroenterology2014,20,7: | 25 |
