| 1 | Adjuvant transcatheter arterial chemoembolization after curative resection for hepatocellular carcinoma patients with solitary tumor and microvascular invasion: a randomized clinical trial of efficacy and safety显示文摘Background:The optimal strategy for adjuvant therapy after curative resection for hepatocellular carcinoma(HCC)patients with solitary tumor and microvascular invasion(MVI)is controversial.This trial evaluated the efficacy and safety of adjuvant transcatheter arterial chemoembolization(TACE)after hepatectomy versus hepatectomy alone in HCC patients with a solitary tumor≥5 cm and MVI.Methods:In this randomized,open-labeled,phase III trial,HCC patients with a solitary tumor≥5 cm and MVI were randomly assigned(1:1)to receive either 1-2 cycles of adjuvant TACE after hepatectomy(Hepatectomy-TACE)or hepatectomy alone(Hepatectomy Alone).The primary endpoint was disease-free survival(DFS);the secondary end-points included overall survival(OS)and adverse events.Results:Between June 1,2009,and December 31,2012,250 patients were enrolled and randomly assigned to the Hepatectomy-TACE group(n=125)or the Hepatectomy Alone group(n=125).Clinicopathological characteristics were balanced between the two groups.The median follow-up time from randomization was 37.5 months[interquartile range 18.3-48.2 months].The median DFS was significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group[17.45 months(95%confidence interval[CI]11.99-29.14)vs.9.27 months(95%CI 6.05-13.70),hazard ratio[HR]=0.70(95%CI 0.52-0.95),P=0.020],respectively.The median OS was also significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group[44.29 months(95%CI 25.99-62.58)vs.22.37 months(95%CI 10.84-33.91),HR=0.68(95%CI 0.48-0.97),P=0.029].Treatment-related adverse events were more frequently observed in the Hepatectomy-TACE group,although these were generally mild and manageable.The most common grade 3 or 4 adverse events in both groups were neutropenia and liver dysfunction.Conclusion:Hepatectomy followed by adjuvant TACE is an appropriate option after radical resection in HCC patients with solitary tumor≥5 cm and MVI,with acceptable toxicity. | Wei Wei Pei-En Jian Shao-Hua Li Zhi-Xing Guo Yong-Fa Zhang Yi-Hong Ling Xiao-Jun Lin Li Xu Ming Shi Lie Zheng Min-Shan Chen Rong-Ping Guo | 2018 | Cancer Communications2018，38，1： | 62 |
| 2 | Jianpi Qingchang decoction alleviates ulcerative colitis by inhibiting nuclear factor-κB activation显示文摘AIM To inve s t igat e t he t he r ape ut ic e f f e c t of Jianpi Qingchang decoction(JPQCD) on dextran sulfate sodium(DSS)-induced ulcerative colitis(UC) in mice.METHODS C57BL/c mice were injected intragastrically with 5% DSS instead of drinking water for 7 d, and their body weight, diarrhea severity and fecal bleeding were monitored, while the mice in the control group were treated with standard drinking water, without DSS. After 7 d, the DSS drinking water was changed to normal water and the DSS group continued with DSS water. The control and DSS groups were given normal saline by intragastric injection. The 5-aminosalicylic acid(5-ASA) group was treated orally with 5-ASA at a dose of 100 mg/kg daily. The JPQCD group was treated orally with JPQCD at a dose of 17.1 g/kg daily. On day 14, the colon length was measured, the colorectalhistopathological damage score was assessed, and protein levels of interleukin(IL)-1β, IL-8 and tumor necrosis factor-alpha(TNF-α) in colon supernatants were measured by enzyme-linked immunosorbent assay. m RNA expression of IL-1β, IL-8, TNF-α and nuclear factor-kappa B(NF-κB) was detected by realtime quantitative polymerase chain reaction. Western blotting was used to detect the protein expression of NF-κB and inhibitor of kappa B. RESULTS Acute inflammation occurred in the mice administered DSS, including the symptoms of losing body weight, loose feces/watery diarrhea and presence of fecal blood; all these symptoms worsened at 7 d. The colons of mice treated with DSS were assessed by histological examination, and the results confirmed that acute inflammation had occurred, as evidenced by loss of colonic mucosa and chronic inflammatory cell infiltration, and these features extended into the deeper layer of the colon walls. The expression levels of IL-1β, IL-8 and TNF-α in the DSS group were higher than those in the control group(P < 0.05), and the expression levels of IL-1β, IL-8 and TNF-α in the JPQCD and 5-ASA groups were lower than those in the DSS group after treating with JPQCD and 5-ASA. Comparing with the DSS group, the mR NA level of IL-1β, IL-8, TNF-α and NF-κB was significantly reduced by 5-ASA and JPQCD. The difference between JPQCD and 5-ASA groups was not statistically significant(P > 0.05). Comparing with the DSS group, due to using JPQCD and 5-ASA, significant suppression of activation in DSSinduced NF-κB and increased phosphorylation of IκB in mice with experimental colitis occurred(P < 0.05). The difference between the JPQCD group and the 5-ASA group was not statistically significant(P > 0.05). CONCLUSION Activation of the NF-κB signaling pathway is inhibited by JPQCD, which shows the potential mechanism by which JPQCD treats UC. | Lie Zheng Ya-Li Zhang Yan-Cheng Dai Xuan Chen De-Liang Chen Yue-Ting Dai Zhi-Peng Tang | 2017 | World Journal of Gastroenterology2017，23，7： | 30 |
| 3 | Jianpi Qingchang decoction regulates intestinal motility of dextran sulfate sodium-induced colitis through reducing autophagy of interstitial cells of Cajal显示文摘AIM To investigate the underlying effect of Jianpi Qingchang decoction(JQD) regulating intestinal motility of dextran sulfate sodium(DSS)-induced colitis in mice. METHODS C57BL/6 mice were randomly divided into four groups: the control group, the DSS group, the JQD group, and the 5-aminosalicylic acid group. Except for the control group, colitis was induced in other groups by giving distilled water containing 5% DSS. Seven days after modeling, the mice were administered corresponding drugs intragastrically. The mice were sacrificed on the 15^(th) day. The disease activity index, macroscopic and histopathologic lesions, and ultrastructure of colon interstitial cells of Cajal(ICC) were observed. The levels of tumor necrosis factor-alpha(TNF-α), interleukin(IL)-1β, IL-10 and interferon gamma(IFN-γ), the expression of nuclear factor-kappa B(NF-κB) p65, c-kit, microtubule-associated protein 1 light chain 3(LC3-Ⅱ) and Beclin-l m RNA, and the colonic smooth muscle tension were assessed. RESULTS Acute inflammation occurred in the mice administered DSS. Compared with the control group, the levels of IL-1β, TNF-α, IL-10 and IFN-γ, the expression of LC3-Ⅱ, Beclin-1 and NF-κB p65 m RNA, and the contractile frequency increased(P < 0.05), the expression of c-kit m RNA and the colonic smooth muscle contractile amplitude decreased in the DSS group(P < 0.05). Compared with the DSS group, the levels of IL-10 and IFN-γ, the expression of c-kit m RNA, and the colonic smooth muscle contractile amplitude increased(P < 0.05), the levels of TNF-α and IL-1β, the expression of LC3-Ⅱ, Beclin-1 and NF-κB p65 m RNA, and the contractile frequency decreased in the JQD group(P < 0.05).CONCLUSION JQD can regulate the intestinal motility of DSS-induced colitis in mice through suppressing intestinal inflammatory cascade reaction, reducing autophagy of ICC, and regulating the network path of ICC/smooth muscle cells. | Yan-Cheng Dai Lie Zheng Ya-Li Zhang Xuan Chen De-Liang Chen Li-Juan Wang Zhi-Peng Tang | 2017 | World Journal of Gastroenterology2017，23，26： | 26 |
| 4 | Gut microbiota contributes to the distinction between two traditional Chinese medicine syndromes of ulcerative colitis显示文摘BACKGROUND Ulcerative colitis(UC)is considered to be closely associated with alteration of intestinal microorganisms.According to the traditional Chinese medicine(TCM)theory,UC can be divided into two disease syndromes called Pi-Xu-Shi-Yun(PXSY)and Da-Chang-Shi-Re(DCSR).The relationships among gut microbiota,TCM syndromes,and UC pathogenesis have not been well investigated.AIM To investigate the role of gut microbiota in UC and the distinction of microbiota dysbiosis between PXSY and DCSR syndromes.METHODS From May 2015 to February 2016,UC patients presenting to LongHua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study.Fresh stool specimens of UC patients with PXSY or DCSR were collected.The feces of the control group came from the health examination population of Longhua Hospital.The composition of gut bacterial communities in stool samples was determined by the pyrosequencing of 16S ribosomal RNA.The high-throughput sequencing reads were processed with QIIME,and biological functions were predicted using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States.RESULTS The composition of gut bacterial communities in 93 stool samples(30 healthy controls,32 patients with PXSY syndrome,and 31 patients with DCSR syndrome)was determined by the pyrosequencing of 16S ribosomal RNA.Beta diversity showed that the composition of the microbiota was different among the three groups.At the family level,Porphyromonadaceae,Rikeneliaceae,and Lachnospiraceae significantly decreased while Enterococcus,Streptococcus,and other potential pathogens significantly increased in UC patients compared to healthy subjects.At the genus level,Parabacteroides,Dorea,and Ruminococcus decreased while Faeca-libacterium showed increased abundance in UC compared to healthy controls.Five differential taxa were identified between PXSY and DCSR syndromes.At the genus level,a significantly increased abundance of Streptococcus was observed in DCSR patients,while Lachnoclostridium increased in PXSY patients.The differential functional pathways of the gut microbiome between the PXSY and DCSR groups mainly included lipid metabolism,immunity,and the metabolism of polypeptides.CONCLUSION Our study suggests that the gut microbiota contributes to the distinction between the two TCM syndromes of UC. | Ya-Li Zhang Li-Ting Cai Jun-Yi Qi Yun-Zheng Lin Yan-Cheng Dai Na Jiao You-Lan Chen Lie Zheng Bei-Bei Wang Li-Xin Zhu Zhi-Peng Tang Rui-Xin Zhu | 2019 | World Journal of Gastroenterology2019，25，25： | 19 |

| 6 | Fecal microbiota transplantation in the metabolic diseases:Current status and perspectives显示文摘With the development of microbiology and metabolomics,the relationship between the intestinal microbiome and intestinal diseases has been revealed.Fecal microbiota transplantation(FMT),as a new treatment method,can affect the course of many chronic diseases such as metabolic syndrome,malignant tumor,autoimmune disease and nervous system disease.Although the mechanism of action of FMT is now well understood,there is some controversy in metabolic diseases,so its clinical application may be limited.Microflora transplantation is recommended by clinical medical guidelines and consensus for the treatment of recurrent or refractory Clostridium difficile infection,and has been gradually promoted for the treatment of other intestinal and extraintestinal diseases.However,the initial results are varied,suggesting that the heterogeneity of the donor stools may affect the efficacy of FMT.The success of FMT depends on the microbial diversity and composition of donor feces.Therefore,clinical trials may fail due to the selection of ineffective donors,and not to faulty indication selection for FMT.A new understanding is that FMT not only improves insulin sensitivity,but may also alter the natural course of type 1 diabetes by modulating autoimmunity.In this review,we focus on the main mechanisms and deficiencies of FMT,and explore the optimal design of FMT research,especially in the field of cardiometabolic diseases. | Lie Zheng Yong-Yi Ji Xin-Li Wen Sheng-Lei Duan | 2022 | World Journal of Gastroenterology2022，28，23： | 5 |
| 7 | Prediction of nitrogen and phosphorus contents in citrus leaves based on hyperspectral imaging显示文摘The nutritional status of citrus leaves is very important to the determining of fertilization plans.The spectrum technique is a quick,un-injured method and is becoming widely used for plant nutrient estimation.The possibility and method of using spectrum technique to estimate the nutrient of citrus leaf was explored in this study.A total amount of 135 leaves from the mature spring shoots of navel orange trees(C.sinensis Osbeck,“Newhall”)were collected and randomly grouped into two sets of samples:100 leaves for the calibration set and 35 leaves for the prediction set.The hyperspectral images were scanned upper and lower side of each leaf and then the total nitrogen(N)and phosphorus(P)contents of each leaf were measured.The raw spectra data were extracted to generate average spectra curves,preprocessed with five different methods,and was used to build N and P content prediction models.The performances of the five preprocessing methods,i.e.,Savitzky-Golay smoothing(SGS),standard normal variate(SNV),multiplicative scatter correction(MSC),first-derivative(1-Der)and second-derivative(2-Der),were tested with linear partial least squares(PLS)models and nonlinear least squares-support vector machine(LS-SVM)models.The results showed that the SG-PLS and PLS were the best for the N predicting(Rp=0.9049,RMSEP=0.1041)and P(Rp=0.9235,RMSEP=0.0514)in citrus leaves,respectively;the hyperspectral image data from leaf‟s upper side predicting better for the contents of N and P.The study suggested that the hyperspectral image data from the upper side of the citrus leaves are suitable for nondestructive estimation of nutrient content. | Liu Yanli Lyu Qiang He Shaolan Yi Shilai Liu Xuefeng Xie Rangjin Zheng Yongqiang Deng Lie | 2015 | International Journal of Agricultural and Biological Engineering2015，8，2： | 5 |
| 8 | Mechanism of Jianpi Qingchang Huashi Recipe in treating ulcerative colitis:A study based on network pharmacology and molecular docking显示文摘BACKGROUND Ulcerative colitis(UC)is a refractory intestinal disease with alternating onset and remission and a long disease course,which seriously affects the health and quality of life of patients.The goal of treatment is to control clinical symptoms,induce and maintain remission,promote mucosal healing,and reduce recurrence.Clinical trials have shown unsatisfactory clinical response rates.As a supplementary alternative medicine,traditional Chinese medicine has a rich history and has shown good results in the treatment of UC.Because of the quality of herbal medicine and other factors,the curative effect of traditional Chinese medicine is not stable enough.The mechanism underlying the effect of Jianpi Qingchang Huashi Recipe(JPQCHSR)on inducing UC mucosal healing is not clear.AIM To investigate the potential mechanism of JPQCHSR for the treatment of UC based on network pharmacology and molecular docking.METHODS Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform was used to extract the active components and action targets of JPQCHSR,and the target names were standardized and corrected through UniProt database.The related targets of UC were obtained through GeneCards database,and the intersection targets of drugs and diseases were screened by jvenn online analysis tool.The visual regulatory network of'Traditional Chinese medicine-active components-target-disease'was constructed using Cytoscape software,the protein interaction network was constructed using STRING database,and enrichment analysis of gene ontology and Kyoto Encyclopedia of Genes and Genomes pathways was conducted through R software.At last,the active components were docked with the core target through SYBYL-X 2.1.1 software.RESULTS Through database analysis,a total of 181 active components,302 targets and 205 therapeutic targets were obtained for JPQCHSR.The key compounds include quercetin,luteolin,kaempferol,etc.The core targets involved STAT3,AKT1,TP53,MAPK1,MAPK3,JUN,TNF,etc.A total of 2861 items were obtained by GO enrichment analysis,and 171 items were obtained by KEGG(Kyoto Encyclopedia of Genes and Genomes)pathway enrichment analysis.The results of molecular docking showed that the key active components in JPQCHSR had certain affinity with the core target.CONCLUSION The treatment of UC with JPQCHSR is a complex process of multi-component,multi-target and multi-pathway regulation.The mechanism of this Recipe in the treatment of UC can be predicted through network pharmacology and molecular docking,so as to provide theoretical reference for it to better play its therapeutic role. | Lie Zheng Xin-Li Wen Yan-Cheng Dai | 2021 | World Journal of Clinical Cases2021，9，26： | 4 |
| 9 | Detection of Huanglongbing(citrus greening) based on hyperspectral image analysis and PCR显示文摘Huanglongbing (HLB, citrus greening) is one of the most serious quarantine diseases of citrus worldwide. To monitor in real-time, recognize diseased trees, and efficiently prevent and control HLB disease in citrus, it is necessary to develop a rapid diagnostic method to detect HLB infected plants without symptoms. This study used Newhall navel orange plants as the research subject, and collected normal color leaf samples and chlorotic leaf samples from a healthy orchard and an HLB-infected orchard, respectively. First, hyperspectral data of the upper and lower leaf surfaces were obtained, and then the polymerase chain reaction (PCR) was used to detect the HLB bacterium in each leaf. The PCR test results showed that all samples from the healthy orchard were negative, and a portion of the samples from the infected orchard were positive. According to these results, the leaf samples from the orchards were divided into disease-free leaves and HLB-positive leaves, and the least squares support vector machine recognition model was established based on the leaf hyperspectral reflectance. The effect on the model of the spectra obtained from the upper and lower leaf surfaces was investigated and different pretreatment methods were compared and analyzed. It was observed that the HLB recognition rate values of the calibration and validation sets based on upper leaf surface spectra under 9-point smoothing pretreatment were 100% and 92.5%, respectively. The recognition rate values based on lower leaf surface spectra under the second-order derivative pretreatment were also 100% and 92.5%, respectively. Both upper and lower leaf surface spectra were available for recognition of HLB-infected leaves, and the HLB PCR-positive leaves could be distinguished from the healthy by the hyperspectral modeling analysis. The results of this study show that early and nondestructive detection of HLBinfected leaves without symptoms is possible, which provides a basis for the hyperspectral diagnosis of citrus with HLB. | Kejian WANG Dongmei GUO Yao ZHANG Lie DENG Rangjin XIE Qiang LV Shilai YI Yongqiang ZHENG Yanyan MA Shaolan HE | 2019 | Frontiers of Agricultural Science and Engineering2019，6，2： | 3 |
| 10 | Ca(NO3)2 canopy spraying during physiological fruit drop period has a better influence on the tree character and fruit quality of Newhall navel orange(Citrus sinensis Osbeck)显示文摘This study aimed to provide a theoretical basis for adopting suitable cultivation measures to tackle calcium(Ca) deficiency in citrus leaves. The Newhall navel orange(Citrus sinensis Osbeck) canopy was sprayed with 20.0 mmol L^(-1) of Ca(NO_3)_2 during physiological fruit drop period, fruit expanding period, and fruit maturing period on 30, 90, and 210 days after full bloom(DAFB), respectively, and its effects on leaf gas exchange parameters and leaf mineral nutrition and fruit quality were analyzed. The results showed that:(1) The photosynthetic rate(ACO_2) at 9:00 a.m. and 16:00 p.m. of fruit expanding period with 30 and 90 DAFB Ca(NO_3)_2 treatments slightly or significantly improved mainly by decreasing stomatal limitation and nonstomatal limitation, respectively.(2) Compared with control(CK), the Ca concentration in leaves with 30, 90, and 240 DAFB Ca(NO_3)_2 treatments increased by 127.16, 97.53, and 33.33%, respectively, and the leaf magnesium concentration also increased by more than 32.26%. However, Ca(NO_3)_2 canopy spraying on 30 DAFB significantly reduced the leaf potassium concentration, by 22.14% compared with CK.(3) Ca(NO_3)_2 canopy spraying on 30 DAFB decreased the second fruit drop rate by 30.55% and increased the weight per fruit by 25.04%, thus resulting in a significant increase in citrus yield.(4) Spraying Ca(NO3) on 30 DAFB mainly affected the metabolism of titratable acid(TA) to improve the maturity of citrus fruits. Whilst it improved the external quality and the coloring of citrus fruit significantly. Therefore, Ca(NO_3)_2 canopy spraying during physiological fruit drop period has a better influence on the tree character and fruit quality of Newhall navel orange(Citrus sinensis Osbeck). | ZHENG Yong-qiang YANG Qiong JIA Xue-mei LIU Yan-mei HE Shao-lan DENG Lie XIE Rang-jin YI Shi-lai Lu Qiang | 2017 | Journal of Integrative Agriculture2017，16，7： | 3 |
| 11 | Value of CT-guided core-needle biopsy in diagnosis and classification of malignant lymphomas using automated biopsy gun显示文摘AIM: To evaluate the value of CT-guided core-needle biopsy in diagnosis and classification of malignant lymphomas.METHODS: From January 1999 to October 2004, CT-guided core-needle biopsies were performed in 80 patients with suspected malignant lymphoma. Biopsies were performed with an 18-20 G biopsy-cut (CR Bard, Inc., Covington, GA,USA) needle driven by a spring-loaded Bard biopsy gun.RESULTS: A definite diagnosis and accurate histological subtype were obtained in 61 patients with a success rate of 76.25% (61/80). Surgical sampling was performed in 19 patients (23.75%) with non-diagnostic core-needle biopsies. The success rate of CT-guided core-needle biopsy varied with the histopathologic subtypes in our group.The relatively high success rates of core-needle biopsy were noted in diffuse large B-cell non-Hodgkin's lymphoma (NHL, 88.89%) and peripheral T-cell NHL (90%). However,the success rates were relatively low in anaplastic large cell (T/null cell) lymphoma (ALCL, 44.44%) and Hodgkin's disease (HD, 28.57%) in our group.CONCLUSION: CT-guided core-needle biopsy is a reliable means of diagnosing and classifying malignant lymphomas,and can be widely applied in the management of patients with suspected malignant lymphoma. | Li Li Qiu-Liang Wu Li-Zhi Liu Yun-Xian Mo Chuan-Miao Xie Lie Zheng Lin Chen Pei-Hong Wu | 2005 | World Journal of Gastroenterology2005，11，31： | 3 |
| 12 | Role of metabolites derived from gut microbiota in inflammatory bowel disease显示文摘Over the past two decades,it is improved gut microbiota plays an important role in the health and disease pathogenesis.Metabolites,small molecules produced as intermediate or end products of microbial metabolism,is considered as one of the major interaction way for gut microbiota with the host.Bacterial metabolisms of dietary substrates,modification of host molecules or bacteria are the major source of metabolites.Signals from microbial metabolites affect immune maturation and homeostasis,host energy metabolism as well as mucosal integrity maintenance.Based on many researches,the composition and function of the microbiota can be changed,which is also seen in the metabolite profiles of patients with inflammatory bowel disease(IBD).Additionally,some specific classes of metabolites also can trigger IBD.In this paper,definition of the key classes of microbialderived metabolites which are changed in IBD,description of the pathophysiological basis of association and identification of the precision therapeutic modulation in the future are the major contents. | Lie Zheng Xin-Li Wen Sheng-Lei Duan | 2022 | World Journal of Clinical Cases2022，10，9： | 3 |
| 13 | New insights into the interplay between intestinal flora and bile acids in inflammatory bowel disease显示文摘Intestinal flora plays a key role in nutrient absorption,metabolism and immune defense,and is considered to be the cornerstone of maintaining the health of human hosts.Bile acids synthesized in the liver can not only promote the absorption of fat-soluble substances in the intestine,but also directly or indirectly affect the structure and function of intestinal flora.Under the action of intestinal flora,bile acids can be converted into secondary bile acids,which can be reabsorbed back to the liver through the enterohepatic circulation.The complex dialogue mechanism between intestinal flora and bile acids is involved in the development of intestinal inflammation such as inflammatory bowel disease(IBD).In this review,the effects of intestinal flora,bile acids and their interactions on IBD and the progress of treatment were reviewed. | Lie Zheng | 2022 | World Journal of Clinical Cases2022，10，30： | 3 |
| 14 | Gut microbiota and inflammatory bowel disease: The current status and perspectives显示文摘Inflammatory bowel disease(IBD)is a chronic immune-mediated disease that affects the gastrointestinal tract.It is argued that environment,microbiome,and immune-mediated factors interact in a genetically susceptible host to trigger IBD.Recently,there has been increased interest in the development,progression,and treatment of IBD because of our understanding of the microbiome.Researchers have proved that some factors can alter the microbiome and the pathogenesis of IBD.As a result,there has been increasing interest in the application of probiotics,prebiotics,antibiotics,fecal microbiota transplantation,and gene manipulation in treating IBD because of the possible curative effect of microbiome-modulating interventions.In this review,we summarize the findings from human and animal studies and discuss the effect of the gut microbiome in treating patients with IBD. | Lie Zheng Xin-Li Wen | 2021 | World Journal of Clinical Cases2021，9，2： | 3 |
| 15 | Computational and Experimental Study of Cooling Process in Coke Dry Quenching Experimental Shaft显示文摘Owing to its merits in energy savings, environmental protection and coke quality improvement, the Coke Dry Quenching (CDQ) technology is favorite in coke making industry today. In order to validate the mathematical model developed for the cooling process of real CDQ shaft, the one-seventh scale experimental setup was established. With the air as the working fluid and the coke as the packed bed, the coke and gas temperatures and the pressure drop in the cooling shaft were measured. A mathematical model based on the non-Darcian and non-thermal equilibrium model for the cooling process of the CDQ experimental shaft was presented. The computational results were compared to the experimental data. It was found that most numerical predictions were supported by the measured values. | Huafei Liu Xinxin Zhang Maolin Wu Yanhui Feng Yingbo Wang Dinan Wang Lie Xu Wenghua Zheng | 2002 | Journal of Thermal Science2002，11，2： | 2 |
