1Prognostic factors of refractory NSCLC patients receiving anlotinib hydrochloride as the third-or further-line treatment显示文摘Objective:Anlotinib hydrochloride is a multitarget tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor,fibroblast growth factor receptor,platelet-derived growth factor receptor,c-Kit,and c-MET;therefore,it exhibits both antitumor and anti-angiogenetic activities.A phase III trial has shown that anlotinib improved progression-free survival(PFS)and overall survival(OS)in patients with advanced non-small cell lung cancer(NSCLC),who presented with progressive disease or intolerance after standard chemotherapy.This study aimed to analyze the characteristics of patients receiving anlotinib treatment to determine the dominant populations who are fit for the treatment.Methods:Data were collected from March 2015 to January 2017 from a randomized,double-blind,placebo-controlled,multicenter,phase III trial of anlotinib(ALTER0303).A total of 437 patients were enrolled and randomly allocated(2:1)to the anlotinib and placebo groups.Kaplan–Meier analysis and log-rank test were performed to compare PFS and OS.Cox proportional hazards model was adopted for multivariate prognostic analysis.Results:Multivariate analysis indicated that high post-therapeutic peripheral blood granulocyte/lymphocyte ratio and elevated alkaline phosphatase levels were independent risk factors for PFS.Meanwhile,elevated thyroid-stimulating hormone,blood glucose,and triglyceride levels;hypertension;and hand–foot syndrome were independent protective factors of PFS.High posttherapeutic peripheral blood granulocyte/lymphocyte ratio,an Eastern Cooperative Oncology Group(ECOG)score≥2,and the sum of the maximal target lesion length at baseline were independent risk factors of OS,and hypertriglyceridemia was an independent protective factor of OS.Conclusions:This study preliminarily explored the possible factors that affected PFS and OS after anlotinib treatment in patients with advanced refractory NSCLC,and the baseline characteristics of the therapeutically dominant populations were then identified.Jing Wang Yizhuo Zhao Qiming Wang Li Zhang Jianhua Shi Zhehai Wang Ying Cheng Jianxing He Yuankai Shi Hao Yu Yang Zhao Weiqiang Chen Yi Luo Xiuwen Wang Kejun Nan Faguang Jin Jian Dong Baolan Li Zhujun Liu Baohui Han Kai Li 2018Cancer Biology & Medicine2018,15,4:46

4Biomimetic nanoparticles for inflammation targeting显示文摘There have been many recent exciting developments in biomimetic nanoparticles for biomedical applications. Inflammation, a protective response involving immune cells, blood vessels,and molecular mediators directed against harmful stimuli, is closely associated with many human diseases.As a result, biomimetic nanoparticles mimicking immune cells can help achieve molecular imaging and precise drug delivery to these inflammatory sites. This review is focused on inflammation-targeting biomimetic nanoparticles and will provide an in-depth look at the design of these nanoparticles to maximize their benefits for disease diagnosis and treatment.Kai Jin Zimiao Luo Bo Zhang Zhiqing Pang 2018Acta Pharmaceutica Sinica B2018,8,1:27
5Fibrinogen-like protein 2/fibroleukin prothrombinase contributes to tumor hypercoagulability via IL-2 and IFN-γ显示文摘AIM: To examine the role of Fibrinogen-like protein 2 (fgl2)/fibroleukin in tumor development. Fgl2 has been reported to play a vital role in the pathogenesis in MHV-3 (mouse hepatitis virus) induced fulminant and severe hepatitis,spontaneous abortion,allo-and xeno-graft rejection by mediating 'immune coagulation'. METHODS: Tumor tissues from 133 patients with six types of distinct cancers and the animal tumor tissues from human hepatocellular carcinoma (HCC) model on nude mice (established from high metastasis HCC cell line MHCC97LM6) were obtained. RESULTS: Hfgl2 was detected in tumor tissues from 127 out of 133 patients as well as tumor tissues collected from human HCC nude mice. Hfgl2 was highly expressed both in cancer cells and interstitial inflammatory cells including macrophages,NK cells,and CD8+ T lymphocytes and vascular endothelial cells. Hfgl2 mRNA was localized in cells that expressed hfgl2 protein. Fibrin (nogen) co-localization with hfgl2 expression was determined by dual immunohistochemical staining. In vitro,IL-2 and IFN-γ increased hfgl2 mRNA by 10-100 folds and protein expression in both THP-1 and HUVEC cell lines. One-stage clotting assays demonstrated that THP-1 and HUVEC cells expressing hfgl2 had increased procoagulant activity following cytokines stimulation. CONCLUSION: The hfg12 contributes to the hypercoagulability in cancer and may induce tumor angiogenesis and metastasis via cytokine induction.Kai Su Fang Chen Wei-Ming Yan Qi-Li Zeng Li Xu Dong Xi Bin Pi Xiao-Ping Luo Qin Ning 2008World Journal of Gastroenterology2008,14,39:20
6BH3-only proteins target BCL-xL/MCL-1,not BAX/BAK,to initiate apoptosis显示文摘It has been widely accepted that mitochondria-dependent apoptosis initiates when select BH3-only proteins(BID,BIM,etc.)directly engage and allosterically activate effector proteins BAX/BAK.Here,through reconstitution of cells lacking all eight pro-apoptotic BH3-only proteins,we demonstrate that all BH3-only proteins primarily target the anti-apoptotic BCL-2 proteins BCL-xL/MCL-1,whose simultaneous suppression enables membrane-mediated spontaneous activation of BAX/BAK.BH3-only proteins*apoptotic activities correlate with affinities for BCL-xL/MCL1 instead of abilities to directly activate BAX/BAK.Further,BID and BIM do not distinguish BAX from BAK or accelerate BAX/BAK activation following inactivation of BCL-xL/MCL-1.Remarkably,death ligandinduced apoptosis in cells lacking BH3-only proteins and MCL-1 is fully restored by BID mutants capable of neutralizing BCL-xL,but not direct activation of BAX/BAK.Taken together,our findings provide a'Membrane-mediated Permissive'model,in which the BH3-only proteins only indirectly activate BAX/BAK by neutralizing the anti-apoptotic BCL-2 proteins,and thus allowing BAX/BAK to undergo unimpeded,spontaneous activation in the mitochondrial outer membrane milieu,leading to apoptosis initiation.Kai Huang Katelyn L.O'Neill Jian Li Wei Zhou Na Han Xiaming Pang Wei Wu Lucas Struble Gloria Borgstahl Zhaorui Liu Liqiana Zhang Xu Luo 2019Cell Research2019,29,11:16

8Oroxindin inhibits macrophage NLRP3 inflammasome activation in DSS-induced ulcerative colitis in mice via suppressing TXNIP-dependent NF-κB pathway显示文摘Oroxindin is a flavonoid isolated from the traditional Chinese medicine Huang-Qin,which has shown various pharmacological activities including anti-inflammatory,antitumor,antioxidant,etc.Thus far,the effect of oroxindin on colonic inflammation and the underlying mechanism remain unknown.In this study,we investigated the tissue distribution of oroxindin and its therapeutic effects on ulcerative colitis(UC)as well as the underlying mechanisms.UC model was established in mice by administrating dextran sulfate sodium(DSS)in drinking water for 7 d.We first showed that oroxindin was largely absorbed by the colon as an active ingredient after normal mice received Huang-Qin-Tang,a traditional Chinese medicine decoction.UC mice were then treated with oroxindin(12.5,25,50 mg-kg^-1·d^-1,i.g.)for 10 d.We found that oroxindin treatment greatly suppressed massive macrophages infiltration and attenuated pathological changes in colonic tissue.Furthermore,oroxindin treatment significantly inhibited the generation of IL-13 and IL-18 in the colon via inhibiting the nucleotide-binding oligomerization domain-like receptor 3(NLRP3)inflammasome formation and activation.In cultured macrophages,LPS induced NLRp3 inflammasome formation and caspase-1 activation,which were suppressed by oroxindin(12.5-50μM).In LPS-treated macrophages,oroxindin dose-dependently restored the expression of TXNIP protein,leading to suppressing TXNIP-dependent NF-κB activation.In conclusion,these results demonstrate that oroxindin could be absorbed by the colon and attenuate inflammatory responses via inhibiting NLRP3 inflammasome formation and activation,which is related to the inhibitory effect on TXNIP-dependent NF-κB-signaling pathway.Hence,oroxindin has the potential of becoming an effective drug for treating UC.Qi Liu Rui Zuo Kai Wang Fei-fei Nong Ya-jun Fu Shao-wei Huang Zeng-feng Pan Yi Zhang Xia Luo Xiang-liang Deng Xiao-xue Zhang Lian Zhou Yang Chen 2020Acta Pharmacologica Sinica2020,41,6:15
9Diagnostic value of elevated serum carbohydrate antigen 199 level in acute cholangitis secondary to choledocholithiasis显示文摘AIM To investigate the diagnostic value of abnormal serum carbohydrate antigen 199(CA199) level in acute cholangitis secondary to choledocholithiasis.METHODS In this retrospective cohort study, the clinical data of 727 patients with choledocholithiasis admitted to the Third Affiliated Hospital of Zunyi Medical College from June 2011 to June 2017 were collected. Among these patients, 258 patients had secondary acute cholangitis and served as observation group, and the remaining 569 choledocholithiasis patients served as the control group. Serum liver function indexes and tumor markers were detected in both groups, and the receiver operating characteristic(ROC) curves were constructed for markers showing statistical significances. The cutoff value, sensitivity, and specificity of each marker were calculated according to the ROC curves. RESULTS The results of liver function tests showed no significant differences between the two groups(P > 0.05). Tumor markers including serum CA125, CA153, carcinoembryonic antigen, and alpha fetoprotein levels were also not significantly different(P > 0.05); however, the serum CA199 level was significantly higher in the observation group than in the control group(P < 0.05). The ROC curve analysis showed that the area under the curve was 0.885(95%CI: 0.841-0.929) for CA199, and the cutoff value of 52.5 kU/L had the highest diagnostic accuracy, with a sensitivity of 86.8% and a specificity of 81.6%.CONCLUSION Abnormally elevated serum CA199 level has an important value in the diagnosis of acute cholangitis secondary to choledocholithiasis. It may be a specific inflammatory marker for acute cholangitis.Yong Mei Li Chen Ci-Jun Peng Jun Wang Peng-Fei Zeng Guo-Xing Wang Wen-Ping Li Yan-Qing Luo Chao Du Kai Liu Kun Xiong Kai Leng Chun-Lin Feng Ji-Hu Jia 2018World Journal of Clinical Cases2018,6,11:11
10Risk factors of intra-abdominal bacterial infection after liver transplantation in patients with hepatocellular carcinoma显示文摘Objective: To explore the risk factors of intra-abdominal bacterial infection(IAI) after liver transplantation(LT) in patients with hepatocellular carcinoma(HCC). Methods: A series of 82 HCC patients who received LT surgeries in our department between March 2004 and April 2010 was recruited in this study. Then we collected and analyzed the clinical data retrospectively. Statistical analysis system(SPSS) software was adopted to perform statistical analysis. Chi-square test, t-test and Wilcoxon rank sum test were used to analyze the clinical data and compute the significance of the incidences of early-stage IAI after LT for HCC patients. Binary logistic regression was performed to screen out the risk factors, and multiple logistic regression analyses were performed to compute the independent risk factors. Results: A series of 13 patients(13/82, 15.9%) had postoperative IAI. The independent risk factors of postoperative intra-abdominal bacterial infections after LT for HCC patients were preoperative anemia [Hemoglobin(HGB) <90 g/L] and postoperative abdominal hemorrhage(72 hours >400 mL), with the odds ratios at 8.121(95% CI, 1.417 to 46.550, P=0.019) and 5.911(95% CI, 1.112 to 31.432, P=0.037). Conclusions: Postoperative IAI after LT in patients with HCC was a common complication. Preoperative moderate to severe anemia, as well as postoperative intra-abdominal hemorrhage more than 400 mL within the first 72 hours might independently indicate high risk of IAI for these patients.Kai Nie Rongzheng Ran Weifeng Tan Bin Yi Xiangji Luo Yong Yu Xiaoqing Jiang 2014Chinese Journal of Cancer Research2014,26,3:10
11Biomass-derived porous carbon highly efficient for removal of Pb(Ⅱ) and Cd(Ⅱ)显示文摘The utilization of abundant and renewable biomass to fabricate advanced functional materials is considered a promising route for environmental applications.Herein,Lignin-based porous carbon with layered graphene-like structure(LPC)is successfully synthesized and applied to efficiently remove Pb(Ⅱ)and Cd(Ⅱ).The as-synthesized LPC materials are systematically characterized and these results show that LPC has a porous graphene-like structure,facilitating the diffusion and immobilization of heavy metal ions.The influence of different reaction parameters(solution pH,initial concentration of metal ions,contact time and adsorbent amount)on the adsorption performance is investigated in details.The results demonstrate that LPC can achieve superior adsorption capacities of 250.5 mg·g^-1 for Pb(Ⅱ)and 126.4 mg·g^-1 for Cd(Ⅱ),which are far superior to the previously reported adsorbents.Pseudo-second order kinetics model and Freundlich isotherm model describe the adsorption process well.Furthermore,the exhausted LPC can be regenerated easily and exhibits the removal efficiency of 96%and 92%for Pb(Ⅱ)and Cd(Ⅱ)after five continuous runs,respectively.This study shows a sustainable strategy for the design of porous carbon material from na?ve biomass and highlights the great potential in wastewater treatment.Anqi Wang Zhikeng Zheng Ruiqi Li Di Hu Yiran Lu Huixia Luo Kai Yan 2019Green Energy & Environment2019,4,4:10

13Effect of heparin on apoptosis in human nasopharyngeal carcinoma CNE2 cells显示文摘In order to study the mechanism of the effect of heparin on apoptosis in carcinoma cells, the nasopharyngeal carcinoma cell line CNE2 was used to identify the effect of heparin on apoptosis associated with the expression of c-myc, bax, bcl-2 proteins by use of Hoechst 33258 staining, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL), agarose gel electrophoresis, and flow cytometry, as well as Western blot analysis. The results showed that heparin induced apoptosis of CNE2 cells including the morphologic changes such as reduction in the volume, and the nuclear chromatin condensation, as well as the “ladder pattern” revealed by agarose gel electrophoresis of DNA in a concentration-dependent manner.The number of TUNEL-positive cells was dramatically increased to 33.6±1.2% from 2.8±0.3% by treat ment with heparin in different concentrations (10~40 kU/L). The apoptotic index was increased to 32.5% from 3.5% by detecting SubG1 peaks on flow cytometry. Western blot analysis showed that levels of bcl-2,bax and c-myc were significantly overexpressed by treatment with the increase of heparin concentrations.These results suggest that heparin induces apoptosis of CNE2 cells, which may be regulated by differential expression of apoptosis-related genes.LI HONG LIANG , KAI HE YE , HAI WEI ZHANG , YING RU LUO , XIAN DA REN, AI HUA XIONG, RUI SITU Department of Pharmacology ,Pharmacy College, Department of Pathology Medical College, Jinan University, Guangzhou 510632, China 2001Cell Research2001,11,4:9
14Surplus dietary isoleucine intake enhanced monounsaturated fatty acid synthesis and fat accumulation in skeletal muscle of finishing pigs显示文摘Background: Isoleucine(Ile) has been implicated in the regulation of energy homeostasis and adipogenesis.However,the impact of surplus dietary Ile intake on muscle lipogenesis remains unknown.The present study aimed to investigate the impact of dietary supplementation of extra-Ile on lipogenesis,fatty acid profile and lipid accumulation in skeletal muscle in finishing pigs.Methods: Forty-eight barrows with initial body weight of 77.0 ± 0.1 kg were allotted to one of two groups and fed diets containing 0.39%,0.53% standardized ileal digestible(SID) Ile with six replicates per treatment and four pigs per replicate for 30 d.Results: Dietary Ile intake significantly improved the intramuscular fat(IMF) content and monounsaturated fatty acid(MUFA) concentration in the skeletal muscle(P < 0.05),and decreased the drip loss and shear force(P < 0.05) without influencing the growth performance of pigs(P > 0.05).Moreover,the phosphorylation of adenosine monophosphate activated protein kinase α(AMPKα) and acetyl coenzyme A carboxylase(ACC) proteins that monitor lipid metabolism were decreased in skeletal muscle of pigs offered extra-Ile diet(P < 0.05).The mRNA expression of adipose-specific genes adipocyte determination and differentiation factor 1(ADD1),fatty acid synthase(FAS),and stearoyl-CoA desaturase(SCD) were upregulated and the activity of SCD was increased as well(P < 0.05).Conclusions: Surplus dietary Ile intake could increase IMF accumulation and MUFA synthesis in skeletal muscle through depressing the phosphorylation of AMPKα-ACC and stimulating the expression and activity of SCD,and increasing the capability of lipogenesis in skeletal muscle.Yanhong Luo Xin Zhang Zhengpeng Zhu Ning Jiao Kai Qiu Jingdong Yin 2019Journal of Animal Science and Biotechnology2019,10,1:9
15Poly(methyl methacrylate) bone cement composited with mineralized collagen for osteoporotic vertebral compression fractures in extremely old patients显示文摘To examine the clinical effects of a new bone cement composed of poly(methyl methacrylate)(PMMA)and mineralized collagen(MC)compared with pure PMMA bone cement in treating osteoporotic vertebral compression fractures(OVCFs)in patients aged over 80.In all,32 cases using pure PMMA bone cement and 31 cases using MC-modified PMMA(MC-PMMA)bone cement for OVCFs between June 2014 and March 2016 were screened as PMMA group and MC-PMMA group,respectively,with an average age of over 80.The operation duration,intraoperative blood loss,hospital stay,oswestry disability index(ODI),visual analogue scale(VAS),anterior vertebral height(AVH),intermediate vertebral height(IVH)and posterior vertebral height(PVH)of injured vertebrae,vertebral computed tomography value,re-fracture rate of adjacent vertebrae,correction rate of spinal kyphotic angle and wedge-shaped vertebra angle and surgical complications were compared between the two groups.In the early post-operative period,the VAS,ODI,AVH and IVH in MC-PMMA group were comparable to those in the traditional PMMA group.Moreover,the MC-PMMA group showed better effects compared with the PMMA group 12months after surgery.Thus,this new bone cement has superior clinic effects in the long term.Kefeng Luo Guoqiang Jiang Jinjin Zhu Bin Lu Jiye Lu Kai Zhang Xiumei Wang Fu-Zhai Cui 2020Regenerative Biomaterials2020,7,1:8
16Depth-aided inpainting for disocclusion restoration of multi-view images using depth-image-based rendering显示文摘A new algorithm is proposed for restoring disocclusion regions in depth-image-based rendering (DIBR) warped images. Current solutions include layered depth image (LDI), pre-filtering methods, and post-processing methods. The LDI is complicated, and pre-filtering of depth images causes noticeable geometrical distortions in cases of large baseline warping. This paper presents a depth-aided inpainting method which inherits merits from Criminisi’s inpainting algorithm. The proposed method features incorporation of a depth cue into texture estimation. The algorithm efficiently handles depth ambiguity by penalizing larger Lagrange multipliers of filling points closer to the warping position compared with the surrounding existing points. We perform morphological operations on depth images to accelerate the algorithm convergence, and adopt a luma-first strategy to adapt to various color sampling formats. Experiments on test multi-view sequence showed that our method has superiority in depth differentiation and geometrical loyalty in the restoration of warped images. Also, peak signal-to-noise ratio (PSNR) statistics on non-hole regions and whole image comparisons both compare favorably to those obtained by state of the art techniques.Kai LUO Dong-xiao LI Ya-mei FENG Ming ZHANG 2009Journal of Zhejiang University-Science A(Applied Physics & Engineering)2009,10,12:7

18Monte Carlo simulation based on Geant4 of single event upset induced by heavy ions显示文摘The present work is a computational simulation of single event upset(SEU) induced by heavy ions passing through the device with Geant4-tool based on Monte Carlo transport code.Key parameters affecting SEU occurrence are examined,and related geometrical construction and critical charge are quantified.The MUlti-Functional Package for SEU Analysis(MUFPSA) has been successfully programmed and applied for SEU occurrence after the completion of device geometrical construction,critical charge,and SEU cross section calculation.The proposed MUFPSA has yielded a good agreement with MRED.Specifically,the results show that higher LET incident ions lead to increased SEU vulnerability due to more diffusion and higher energy deposition.In addition,the analytical method of radial ionization profile provides a good complementary interpretation.GENG Chao LIU Jie ZHANG ZhanGang HOU MingDong SUN YouMei XI Kai GU Song DUAN JingLai YAO HuiJun MO Dan LUO Jie 2013Science China(Physics,Mechanics & Astronomy)2013,56,6:6
19Benzoate anions-intercalated NiFe-layered double hydroxide nanosheet array with enhanced stability for electrochemical seawater oxidation显示文摘Seawater electrolysis is an extremely attractive approach for harvesting clean hydrogen energy,but detrimental chlorine species(i.e.,chloride and hypochlorite)cause severe corrosion at the anode.Here,we report our recent finding that benzoate anions-intercalated NiFe-layered double hydroxide nanosheet on carbon cloth(BZ-NiFe-LDH/CC)behaves as a highly efficient and durable monolithic catalyst for alkaline seawater oxidation,affords enlarged interlayer spacing of LDH,inhibits chlorine(electro)chemistry,and alleviates local pH drop of the electrode.It only needs an overpotential of 320 mV to reach a current density of 500 mA·cm^(−2)in 1 M KOH.In contrast to the fast activity decay of NiFe-LDH/CC counterpart during long-term electrolysis,BZ-NiFe-LDH/CC achieves stable 100-h electrolysis at an industrial-level current density of 500 mA·cm^(−2)in alkaline seawater.Operando Raman spectroscopy studies further identify structural changes of disorderedδ(NiIII-O)during the seawater oxidation process.Longcheng Zhang Jie Liang Luchao Yue Kai Dong Jun Li Donglin Zhao Zerong Li Shengjun Sun Yongsong Luo Qian Liu Guanwei Cui Abdulmohsen Ali Alshehri Xiaodong Guo Xuping Sun 2022Nano Research Energy2022,1,3:6
20Sedimentary Evolution of the Qinghai-Tibet Plateau in Cenozoic and its Response to the Uplift of the Plateau显示文摘We have studied the evolution of the tectonic lithofacies paleogeography of Paleocene-Eocene, Oligocene, Miocene, and Pliocene of the Qinghai-Tibet Plateau by compiling data regarding the type, tectonic setting, and lithostratigraphic sequence of 98 remnant basins in the plateau area. Our results can be summarized as follows. (1) The Paleocene to Eocene is characterized by uplift and erosion in the Songpan-Garzê and Gangdisê belts, depression (lakes and pluvial plains) in eastern Tarim, Qaidam, Qiangtang, and Hoh Xil, and the Neo-Tethys Sea in the western and southern Qinghai-Tibet Plateau. (2) The Oligocene is characterized by uplift in the Gangdisê-Himalaya and Karakorum regions (marked by the absence of sedimentation), fluvial transport (originating eastward and flowing westward) in the Brahmaputra region (marked by the deposition of Dazhuka conglomerate), uplift and erosion in western Kunlun and Songpan-Garzê, and depression (lakes) in the Tarim, Qaidam, Qiangtang, and Hoh Xil. The Oligocene is further characterized by depressional littoral and neritic basins in southwestern Tarim, with marine facies deposition ceasing at the end of the Oligocene. (3) For the Miocene, a widespread regional unconformity (ca. 23 Ma) in and adjacent to the plateau indicates comprehensive uplift of the plateau. This period is characterized by depressions (lakes) in the Tarim, Qaidam, Xining-Nanzhou, Qiangtang, and Hoh Xil. Lacustrine facies deposition expanded to peak in and adjacent to the plateau ca. 18-13 Ma, and north-south fault basins formed in southern Tibet ca. 13-10 Ma. All of these features indicate that the plateau uplifted to its peak and began to collapse. (4) Uplift and erosion occurred during the Pliocene in most parts of the plateau, except in the Hoh Xil-Qiangtang, Tarim, and Qaidam. The continuous uplift and intensive taphrogeny in the plateau divided the original large basin into small basins, deposition of lacustrine facies decreased considerably, and boulderstone accumulated, indicating a response to the overall uplift of the plateau. Here, we discuss the evolution of tectonic lithofacies paleogeography in Cenozoic and its response to the tectonic uplift of the Qinghai-Tibet Plateau in relation to the above characteristics. We have recognized five major uplift events, which occurred during 58-53 Ma, 45-30 Ma, 25-20 Ma, 13-7 Ma, and since 5 Ma. The results presented here indicate that the paleogeomorphic configurations of the Qinghai-Tibet Plateau turned over during the late Miocene, with high elevations in the east during the pre-Miocene switching to high contours in the west at the end of Miocene.ZHANG Kexin WANG Guocan XU Yadong LUO Mansheng JI Junliang XIAO Guoqiao WANG An SONG Bowen LIANG Yinpin JIANG Shangsong CAO Kai CHEN Fenning CHEN Ruiming YANG Yongfeng 2013Acta Geologica Sinica(English Edition)2013,87,2:6
