| 1 | Hepatocellular Carcinoma-Cause,Treatment and Metastasis显示文摘In the recent decades, the incidence of hepatocellular carcinoma (HCC) has been found to be increasing in males in some countries. In China, HCC ranked second of cancer mortality since 1990s. Hepatitis B and C viruses (HBV and HCV) and dietary aflatoxin intake remain the major causative factors of HCC. Surgery plays a major role in the treatment of HCC, particularly for small HCC. Downstaging unresectable huge HCC to smaller HCC and followed by resection will probably be a new approach for further study. Liver transplantation is indicated for small HCC, however, some issues remain to be solved.Different modes of 'regional cancer therapy for HCC' have been tried. Systemic chemotherapy has been disappointing in the past but the future can be promising.Biotherapy, such as cytokines, differentiation inducers,anti-angiogenic agents, gene therapy and tumor vaccine will probably play a role, particularly in the prevention of tumor recurrence. HCC invasiveness is currently the major target of study. Tremendous works have been done at the molecular level, which will provide clues for biomarker of HCC progressionas well as targets for intervention. | Zhao-You Tang Liver Cancer Institute & Zhongshan Hospital of Fudan University Professor of Surgery Chairman.Liver Cancer Institute of Fudan University(previous Liver Cancer Institute of Shanghai Medical University)136 Yixueyuan Road,Zhongshan Hospital,Shanghai 200032,China. | 2001 | World Journal of Gastroenterology2001,7,4: | 213 |
| 2 | Establishment of cell clones with different metastatic potential from the metastatic hepatocellular carcinoma cell line MHCC97显示文摘ALM To establish clone cells with different metastatic potential for the study of metastasis-related mechanisms. METHODS Cloning procedure was performed on parental hepatocellular carcinoma (HCC) cell line MHCC97. andbiological characteristics of the target clones selected by in vivo screening were studied.``RESULTS Two clones with high MHCC97-H and IowMHCC9--L1 metastatic potential were isolated from theparent cell line. Compared with MHCC97-L. MHCC97-H hadsmaller cell size average cell diameter 43 um vs 50 μmand faster in vitro and in vivo growth rate tumor celldoubling time was 34.2 h vs 60.0 h. The main ranges ofchromosomes were 5.5 58 in MHCC97-H and 57 62 inMHCC97-L. Boyden chamber in vitro invasion assay demonstrated that the number of penetrating cells through the artificial basement membrane was 137.5 - 11 .0) cellsfield for MHC_C99--H vs 17.7 - 6.3) field for MHCC97-L.The proportions of cells in GO Gl phase. S phase, and G_ M phase for MHCC97-H MHCC97-L were 0.56 6.65.0.28 0.25 and 0.l6 0.10, respectively, as measured by flow cytometry. The serum AFP levels in nude mice 5 wk after orthotopic implantation of tumor tissue were ( 24666 μg. L for MHCC97-H and (91- 66) μg' L 1 for MHCC97L.

| 3 | Increasing the frequency of CIK cells adoptive immunotherapy may decrease risk of death in gastric cancer patients显示文摘AIM: To analyze the correlation between cytokineinduced killer (CIK) cells adoptive immunotherapy and cancer-related death in gastric cancer patients. METHODS: One hundred and fifty-six gastric cancer patients after operation at the Third Affiliated Hospital of Soochow University were enrolled in this study. Their clinical data including demographic characteristics, operation time, tumor size, pathological type and staging, tumor metastasis, outcome of chemotherapy or CIK cells adoptive immunotherapy, survival time or time of death were collected with a standard structured questionnaire. Kaplan-Meier method was used to estimate the median survival time, and the 2- and 5- year survival rates. Hazard risk (HR) and 95% confidence interval (95% CI) of CIK cells adoptive immunotherapy for gastric cancer were calculated using the two-stage time-dependent covariates Cox model. RESULTS: The survival time of gastric cancer patients was longer after CIK cells adoptive immunotherapy than after chemotherapy (χ 2 = 10.907, P = 0.001). The median survival time of gastric cancer patients was also longer after CIK cells adoptive immunotherapy than after chemotherapy (49 mo vs 27 mo, P < 0.05). The 2- and 5-year survival rates of gastric cancer patients were significantly higher after CIK cells adoptive immunotherapy than after chemotherapy (73.5% vs 52.6%, 40.4% vs 23.9%, P < 0.05). A significant difference was observed in the survival curve for patients who received CIK cells adoptive immunotherapy (0, 1-10, 11-25, and over 25 frequencies) (χ 2 = 14.534, P = 0.002). The frequencies of CIK cells adoptive immunotherapy were significantly related with the decreasing risk of death in gastric cancer patients after adjustment for sex and age of the patients, tumor stage and relapse (HR = 0.54, 95% CI: 0.36-0.80) when the first stage Cox model was used to define the subjects who remained alive beyond 36 mo as survivors. However, no correlation was observed between the frequencies of death in CIK cells adoptive immunotherapy and the risk of gastric cancer patients (HR = 1.09, 95% CI: 0.63-0.89) when the second stage Cox model was used to define the subjects who survived for more than 36 mo as survivors. CONCLUSION: The survival time of the gastric cancer patients treated with chemotherapy combined with CIK cells adoptive immunotherapy is significantly longer than that of the patients treated with chemotherapy alone and increasing the frequency of CIK cells adoptive immunotherapy seems to benefit patients more. | Jing-Ting Jiang, Chang-Ping Wu, Lu-Jun Chen, Xiao Zheng, Department of Tumor Biological Treatment, Third Affiliated Hospital of Soochow University, Changzhou 213003, Jiangsu Province, China Yi-Bei Zhu, Jing Sun, Xue-Guang Zhang, Key Laboratory of Stem Cell of Jiangsu Province, Institute of Biotechnology, Key Laboratory of Clinical Immunology of Jiangsu Province, Soochow University, Suzhou 215123, Jiangsu Province, China Yue-Ping Shen, Wen-Xiang Wei, Department of Medicine, Soochow University, Suzhou 215123, Jiangsu Province, China Bin-Feng Lu, Department of Immunology, University of Pitts- burgh School of Medicine, Pittsburgh, PA 15261, United States | 2010 | World Journal of Gastroenterology2010,16,48: | 82 |

| 7 | An analysis of 10218 ulcerative colitis cases in China显示文摘AIM: To analyze the characteristics of ulcerative colitis(UC)in Chine.METHODS: From 1981 to 2000, a total of 10218 patients of UCreported in Chinese medical literature and including ourcases diagnosed were analyzed according to the diagnosticcriteria of Lennard-Jones.RESULTS: The number of cases increased by 3.08 times overthe past 10 years (2506 patients were diagnosed from 1981 to1990 while 7512 patients were diagnosed from 1991 to 2000).Lesion renge were described in 7966 patients, 5592 (70.20%)were proctosigmoiditis or proctitis, 1792(22.50%) left-sidedcolitis, 582(7.30%) pancolitis. Among the 8122 patients,2826 (34.8%) had first episole, 4272 (52.6%) had chronicrelapse, 869 (10.7%) were of chronic persist type, 154(1.9%) were of acuts fulminant tyle. The course of theillress were described in 5867 patients, 4427(75.5%) wereless than 5 years, 910 (15.5%) between 5 and 10 years, 530(9.1%) more then 10 years. Six hundred and sixteenpatients patients (6.1% ) had extraintestinal manifestations.The mean age at the diagnosis was 40.7 years( range 6-8 years, and the peak ages 30-49 years). The male to femaleratio was1.09. Among 270 patients diagnosed in ourhospital, 36 had histories of smoking, there was no negativeassociation between the severity of UC and smoking ( P >0.05), 21 smokers were followed up for one year, 15 of themhad given up smoking when the disease were diagnosed,and one year later, 7 patients relapsed, another 6 patientscontinued smoking, and one year later, 2 patients relapsed.Among 270 UC patients diagnosed in our hospital, 4 patients(1.48%) from 2 families had familial history of UC.Treatment was mentioned in 6859 patients, only SASP and/or corticosteroid only in 1276 patients(18.6%), only Chineseherbs in 1377 patients (20.1%), combined Chinese andwestern medicine in 4056 patients (59.1%), surgery wasperformed in 87 patients (1.3%), other treatments in 63patients(0.9%).CONCLUSIONS: In China, number of UC patients increasedsignificantly in the past 10 years. Lesions are commonlylocated to left side colon. The course is short with rereextraintestinal manifestations. The age of onset is relativelyhigh. Males and females are nearly equally affected. Nonegative relation was found between smoking and severityof the disease. Familial relatives are rarely involved.Traditional Chinese medicine (TCM) is widely used in thetreatment of UC. | Xue-Liang Jiang Department of Gastroenterology,Chinese PLA General Hospital of Jinan Command,Jinan 250031,China Hui-Fei Cui Department of Biochemical Pharmaceutics,Shandong University,Jinan 250012,Shandong Province,China | 2002 | World Journal of Gastroenterology2002,8,1: | 217 |
| 8 | The prognostic molecular markers in hepatocellular carcinoma显示文摘The prognosis of hepatocellular carcinoma (HCC) stillremains dismal, although many advances in its clinicalstudy have been made. It is important for tumor control toidentity the factors that predispose patients to death. Withnew discoveries in cancer biology, the pathological andbiological prognostic factors of HCC have been studied quiteextensively. Analyzing molecular markers (biomarkers) withprognostic significance is a complementary method. A largenumber of molecular factors have been shown to associatewith the invasiveness of HCC, and have potential prognosticsignificance. One important aspect is the analysis ofmolecular markers for the cellular malignancy phenotypeThese include alterations in DNA ploidy, cellularproliferation markers (PCNA, Ki-67, Mcm2, MIB1, MIA, andCSE1L/CAS protein), nuclear morphology, the p53 geneand its related molecule MDM2, other cell cycle regulators(cyclin A, cyclin D, cyclin E, cdc2, p27, p73), oncogenesand their receptors (such as ras, c-myc, c-fms, HGF, c-met, and erb-B receptor family members ), apoptosisrelated factors (Fas and FasL), as well as telomeraseactivity. Another important aspect is the analysis ofmolecular markers involved in the process of cancerinvasion and metastasis. Adhesion molecules (E-cadherin,catenins, serum intercellular adhesion molecule-1, CD44variants), proteinases involved in the clegradation ofextracellular matrix (MMP-2, MMP-9, uPA, uPAR, PAl), aswell as other molecules have been regarded as biomarkersfor the malignant phenotype of HCC, and are related toprognosis and therapeutic outcomes. Tumor angiogenesisis critical to both the growth and metastasis of cancersincluding HCC, and has drawn much attention in recentyears. Many angiogenesis-related markers, such as vascularendothelial growth factor (VEGF), basic fibroblast growthfactor (bFGF), platelet-derived endothelial cell growth factor( PD-ECGF ), thrombospondin ( TSP ), angiogenin,pleiotrophin, and endostatin (ES) levels, as well asinratumor microvessel density (MVD) have been evaluatedand found to be of prognostic significance. Body fluid(particularly blood and urinary) testing for biomarkers iseasily accessible and useful in clinical patients. Theprognostic significance of circulating DNA in plasma orserum, and its genetic alterations in HCC are otherimportant trends. More attention should be paid to thesetwo areas in future. As the progress of the human genomeproject advances, so does a clearer understanding of tumorbiology, and more and more new prognostic markers withhigh sensitivity and specificity will be found and used inclinical assays. However, the combination of some items, i.e., the pathological features and some biomarkersmentioned above, seems to be more practical for now. | Lun-Xiu Qin Zhao-You Tang,Liver Cancer Institute and Zhongshan Hospital,Fudan University,Shanghai,China | 2002 | World Journal of Gastroenterology2002,8,3: | 162 |
| 9 | Clinical observation of salvianolic acid B in treatment of liver fibrosis in chronic hepatitis B显示文摘AIM: To evaluate the clinical efficacy of salvianolic acidB (SA-B) on liver fibrosis in chronic hepatitis B.METHODS: Sixty patients with definite diagnosis of liverfibrosis with hepatitis B were included in the trial.Interferon-γ (IFN-γ) was used as control drug. Thepatients took orally SA-B tablets or received muscularinjection of IFN-γ in the double blind randomized test,The complete course lasted 6 months. The histologicalchanges of liver biopsy specimen before and after thetreatment were the main evidence in evaluation, incombination with the results of contents of serum HA,LN, Ⅳ-C, P-Ⅲ-P, liver ultrasound imaging, andsymptoms and signs.RESULTS: Reverse rate of fibrotic stage was 36.67 % inSA-B group and 30.0 % in IFN-γgroup. Inflammatoryalleviating rate was 40.0 % in SA-B group and 36.67 %in IFN-γ group. The average content of HA and Ⅳ-Cwas significantly lower than that before treatment. Theabnormal rate also decreased remarkably. Overallanalysis of 4 serological fibrotic markers showedsignificant improvement in SA-B group as comparedwith the IFN-γgroup. Score of liver ultrasound imagingwas lower in SA-B group than in IFN-γgroup (HA 36.7 %vs80 %,Ⅳ-C 3.3 % vs23.2 %). Before the treatment,ALT AST activity and total bilirubin content of patientswho had regression of fibrosis after oral administrationof SA-B, were significantly lower than those of patientswho had aggravation of fibrosis after oraladministration of SA-B. IFN-γ showed certain sideeffects (fever and transient decrease of leukocytes,occurrence rates were 50 % and 3.23 %), but SA-Bshowed no side effects.CONCLUSION: SA-B could effectively reverse liverfibrosis in chronic hepatitis B. SA-B was better than IFN-γ in reduction of serum HA content, overall decrease of4 serum fibrotic markers, and decrease of ultrasoundimaging score. Liver fibrosis in chronic hepatitis B withslight liver injury was more suitable to SA-B in anti-fibrotic treatment. SA-B showed no obvious side effects. | Ping Liu Yi-Yang Hu Cheng Liu Hui-Ming Xue Zhi-Qiang Xu Lie-Ming Xu Cheng-Hai Liu Hong-Tu Gu Shanghai University of Traditional Chinese Medicine,Shanghai 200032,China Da-Yuan Zhu Shanghai Institute of Metaria Medica,Chinese Academy of Sciences,Shanghai 200031,China Zhi-Qing Zhang the 4~(th) Hualyin City Hospital,Hualan City,223000,JiangSu Province,China | 2002 | World Journal of Gastroenterology2002,8,4: | 85 |

| 11 | PTEN encoding product:a marker for tumorigenesis and progression of gastric carcinoma显示文摘AIM: To detect the expression of PTEN encoding productin normal mucosa, intestinal metaplasia (IM), dysplasia andcarcinoma of the stomach, and to investigate its clinicalimplication in tumorigenesis and progression of gastriccarcinoma.METHODS: Formalin-fixed paraffin embedded specimens from184 cases of gastric carcinoma, their adjacent normal mucosa,IM and dysplasia were evaluated for PTEN protein expressionby SABC immunohistochemistry. PTEN expression wascompared with tumor stage, lymph node metastasis, Lauren'sand WHO's histological classification of gastric carcinoma.Expression of VEGF was also detected in 60 cases of gastriccarcinoma and its correlation with PTEN was concerned.RESULTS: The positive rates of PTEN protein were 100 %(102/102), 98.5 %(65/66), 66.7 % (4/6) and 47.8 %(88/184)in normal mucosa, IM, dysplasia and carcinoma of the stomach,respectively. The positive rates in dysplasia and carcinomawere lower than in normal mucosa and IM (P<0.01).Advanced gastric cancers expressed less frequent PTEN thanearly gastric cancer (42.9 % v567.6 %, P<0.01). The positiverate of PTEN protein was lower in gastric cancer with thanwithout lymph node metastasis (40.3 % v563.3 %, P<0.01).PTEN was less expressed in diffuse-type than in intestinal-type gastric cancer (41.5 % v557.8 %,P<0.05). Signet ringcell carcinoma showed the expression of PTEN at the lowestlevel (25.0 %, 7/28); less than well and moderatelydifferentiated ones (P<0.01). Expression of PTEN was notcorrelated with expression of VEGF (P>0.05).CONCLUSION: Loss or reduced expression of PTEN proteinoccures commonly in tumorigenesis and progression of gastriccarcinoma. It is suggested that PTEN can be an objective markerfor pathologically biological behaviors of gastric carcinoma. | Lin Yang Li-Ge Kuang Hua-Chuan Zheng Jin-Yi Li Dong-Ying Wu Su-Min Zhang Yan Xin No.4 Lab,Cancer Institute,The First Affiliated Hospital,China Medical University,Shenyang 110001,China Ying Chen Shen Yang Gynecology & Obstetrics Hospital,Shenyang 110014,China | 2003 | World Journal of Gastroenterology2003,9,1: | 127 |
| 12 | Multimodality treatment in hepatocellular carcinoma patients with tumor thrombi in portal vein显示文摘AIM To compare the therapeutic effect andsignificances of multimodality treatment forhepatocellular carcinoma (HCC) with tumorthrombi in portal vein (PVTT).METHODS HCC patients (n = 147) with tumortrombi in the main portal vein or the first branchof portal vein were divided into four groups bythe several therapeutic methods. There wereconservative treatment group in 18 out ofpatients (group A); and hepatic artery ligation(HAL) and/or hepatic artery infusion (HAl)group in 18 patients (group B), in whompostoberative chemoembolization was doneperiodically; group of removal of HCC with PVTTin 79 (group C) and group of transcatheterhepatic arterial chemoembolization (TACE) orHAl and/or portal vein infusion (PVI) afteroperation in 32 (group D).RESULTS The median survival period was 12months in our series and the 1-, 3-, and 5-yearsurvival rates were 44.3%, 24.5% and 15.2%,respectively. The median survival times were 2,5, 12 and 16 months in group A, B, C and D,respectively. The 1-, 3- and 5-year survival rateswere 5.6%, 0% and 0% in group A; 22.2%,5.6% and 0% in group B; 53.9%, 26.9% and16.6% in group C; 79.3%, 38.9% and 26.8% ingroup D, respectively. Significant differenceappeared in the survival rates among the groups(P<0.05).CONCLUSION Hepatic resection with removalof tumor thrombi and HCC should increase thecurative effects and be encouraged for theprolongation of life span and quality of life forHCC patients with PVTT, whereas the besttherapeutic method for HCC with PVTT is withregional hepatic chemotherapy orchemoemblization after hepatic resection withremoval of tumor thrombi. | Jia Fan Zhi Quan Wu Zhao You Tang Jian Zhou Shuang Jian Qiu Zeng Chen Ma Xin Da Zhou Sheng Long Ye Liver Cancer Institute, Zhongshan Hospital, Fudan University Medical Center (Former Shanghai University), 136 Yixueyuan Road, Shanghai 200032, China | 2001 | World Journal of Gastroenterology2001,7,1: | 80 |
| 13 | Inhibiting effect of antisense oligonucleotides phosphorthioate on gene expression of TIMP-1 in rat liver fibrosis显示文摘AIM To observe the inhibition of antisenseoligonucleotides (asON) phosphorthioate to thetissue inhibitors metalloproteinase-1 (TIMP-1)gene and protein expression in the liver tissue ofimmunologically induced hepatic fibrosis rats.The possibility of reversing hepatic fibrosisthrough gene therapy was observed.METHODS Human serum albumin (HSA) wasused to attack rats, as hepatic fibrosis model, inwhich asONs were used to block the gene andprotein expressing TIMP-1. According to theanalysis of modulator, structure protein, codingseries of TIMP-1 genome, we designed fourdifferent asONs. These asONs were injected intothe hepatic fibrosis models through coccygealvein. The results was observed by RT-PCR formeasuring TIMP-1 mRNA expression,immunohistochemistry and in situ hybridizationfor collagen Ⅰ, Ⅲ, special staining of collagenfiber, and electron microscopic examination.RESULTS Hepatic fibrosis could last within 363days in our modified model. The expressinglevel of TIMP-1 was high during hepatic fibrosisprocess. It has been proved by theimmunohistochemical and the electronmicroscopic examination that the asONphosphorthioate of TIMP-1 could exactly expressin vivo. The effect of colchicine wasdemonstrated to inhibit the expressing level ofmRNA and the content of collagen Ⅰ, Ⅲ in theliver of experimental hepatic fibrosis rats.However, the electron microscopy research andthe pathologic grading of hepatic fibrosisshowed that there was no significant differencebetween the treatment group and the modelgroup (P>0.05).CONCLUSION The experimental rat model ofhepatic fibrosis is one of the preferable modelsto estimate the curative effect of anti-hepaticfibrosis drugs. The asON phosphorthioate ofTIMP-1 could block the gene and proteinexpression of TIMP-1 in the liver of experimentalhepatic fibrosis rats at the mRNA level.

| 14 | Growth inhibition and apoptosis induction Sulindac on Human gastric cancer cells显示文摘AIM: To evaluate the effects of sulindac in inducing growth inhibition and apoptosis of human gastric cancer cells in comparison with human hepatocellular carcinoma (HCC)cells.METHODS: The human gastric cancer cell lines MKN45 and MKN28 and human hepatocellular carcinoma cell lines HepG2and SMMC7721 were used for the study. Anti-proliferative effect was measured by MTT assay, and apoptosis was determined by Hoechst-33258 staining, electronography and DNA fragmentation. The protein of cyclooxygenase-2 (COX(2) and Bcl-2 were detected by Westem dot blotting.RESULTS: Sulindac could initiate growth inhibition and apoptosis of MKN45, MKN28, HepG2 and SMMC7721 cells in a dose-and time-dependent manner. Growth inhibitory activity and apoptosis were more sensitive in HepG2 cells than in SMMC7721 cells, MKN45 and MKN28 cells. After 24hours incubation with sulindac at 2mmol. L-1 and 4mmol.L-1, the level of COX-2 and Bcl-2 protein were lowered in MKN45, SMMC7721 and HepG2 cells but not in MKN28 cells.CONCLUSION: Sulindac could inhibit the growth of gastric cancer cells and HCC cells effectively in vitro by apoptosis induction, which was associated with regression of COX-2and Bcl-2 expression. The growth inhibition and apoptosis of HCC cells were greater then that of human gastric cancer cells. The different effects of apoptosis in gastric cancer cells may be related to the differentiation of the cells. | Yun-Lin Wu~1 Bo Sun~1 Xue-Jun Zhang~2 Sheng-Nian Wang~2 Heng-Yi He~2 Min-Min Qiao~1 Jie Zhong~1 Jia-Yu Xu~1 1 Department of Gastroenterology,Ruijin Hospital,Shanghai Second Medical University,Shanghai 200025,China2 Institude of Biochemistry and Cell Biology,Shanghai Institues for Biological Sciences,Chinese Academy of Sciences.Shanghai 200025,China | 2001 | World Journal of Gastroenterology2001,7,6: | 64 |
| 15 | Association of H.pylori infection with gastric carcinoma:a Meta analysis显示文摘AIM: To follow the principles of evidence based medicine to reach the integrated results of these studies.METHODS: Twenty-one papers of case-control studies were selected, including 11 on gastric cancer, 7 on precancerous lesion of stomach and 3 on lymphoma of stomach: Meta analysis was used to sum up the odds ratios (OR) of these studies.RESULTS: H. Pylori vsgastric cancer (intestinal and diffuse type): the odds ratio from the fixed effect model is 3.0016(95% Cl 2.4197-3.7234, P < 0.001 ). H. Pylori vs precancerous lesion of stomach: a random effect model was used to calculate the summary odds ratio and its value is 2.5635 (95% Cl: 1.8477-3.5566, P < 0.01). H. Pylori vs lymphoma of stomach: though the quantity of literature is too small to make Meta analysis, the data of these 3 studies show that lymphoma of stomach is highly associated with H. Pylori infections.CONCLUSION: Since it had been revealed that H. Pylori infection pre-exists in gastric carcinoma and precancerous lesions, the results of Meta analysis present a strong evidence to support the conclusion that H. Pylori infection is a risk factor for gastric carcinoma. | Fu-Bo Xue~1 Yong-Yong Xu~1 Yi Wan~1 Bo-Rong Pan~2 Jun Ren~2 Dai-Ming Fan~3 1 Department of Health Statistics,Department of2 Oncology3 Gastroenterology of XiJing Hospital,the Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China | 2001 | World Journal of Gastroenterology2001,7,6: | 66 |
| 16 | Analysis of in vivo patterns of caspase 3 gene expression in primary hepatocellular carcinoma and its relationship to p21^(WAF1) expression and hepatic apoptosis显示文摘AIM To detect the expression of caspase 3gene in primary human hepatocellular carcinoma(HCC)and investigate its relationship to p21WAF1gene expression and HCC apoptosis.METHODS In situ hybridization was employedto determine caspase 3 and p21WAF1expression inHCC.In situ end-labeling was used to detecthepatocytic apoptosis in HCC.RESULTS Twenty-one of 39(53.8%)cases ofHCC were found to express caspase 3transcripts,while 45.2% of HCC failed toexpress caspase 3.Non-cancerous adjacent livertissues showed more positive caspase 3(87.5%,7/8)as compared with HCC(P<0.05).The expression of caspase 3 is correlated withHCC differentiation,72.2%(13/18)ofmoderately to highly differentiated HCC showedcaspase 3 transcripts positive,while only 38.1%of poorly differentiated HCC harbored caspase 3transcripts(P<0.05).No relationship wasfound between caspase 3 expression and tumorsize or grade or metastasis,although 52.5%(5/8)of HCC with metastasis were caspase 3positive and a little higher than that with nometastasis(51.6%,P>0.05).Expression of caspase 3 alone did not affect the apoptosisindex(AI)of HCC.The AI was 7.12%o in caspase3-positive tumors(n=21),while in caspase 3-negative cases(n=18)6.59%0(P>0.05).Expression of caspase 3 clearly segregated withp21WAF1positive tumors as compared withp21WAF1-negative cases(16 of 23,69.6% versus5 of 16,31.3%)with statistical significance(P=0.017).In the cases with positive caspase 3and negative p21WAF1,the Al was found slightlyhigher,but with no statistical significance,thanthat with expression of p21WAF1and caspase 3(7.21‰ vs 6.98‰,P>0.05).CONCLUSION Loss of caspase 3 expressionmay contribute to HCC carcinogenesis,althoughthe expression of caspase 3 does not correlatewell with cell apoptosis in HCC.p21WAF1may bemerely one of the inhibitors which can reducecaspase 3 mediated cell apoptosis in HCCs. | Bao Hua Sun Jun Zhang Bao JǜWang Xi Ping Zhao You Kun Wang Zhi Qun Yu Dong Liang Yang Lian Jie Hao Department of Clinical Immunology,Tongji Hospital,Tongji Medical University,Wuhan 430030,Hubei Province,China | 2000 | World Journal of Gastroenterology2000,6,3: | 65 |
| 17 | The prognostic significance of clinical and pathological features in hepatocellular carcinoma显示文摘The prognosis of patients with HCC still remains dismal. The life expectancy of HCC patients is hard to predict because of the high possibility of postoperative recurrence. Many factors, such as patient's general conditions, macroscopic tumor morphology, as well as tumor hictopathology features, have been proven of prognostic significance. Female HCC patient often has a better prognosis than male patient, which might be due to the receptor of sex hormones. Younger patients often have tumors with higher invasiveness and metastatic potentials, and their survival and prognosis are worse than the older ones. Co-existing hepatitis status and hepatic functional reserve have been confirmed as risk factors for recurrence. Serum alpha-fetoprotein (AFP) is useful not only for diagnosis, but also as a prognostic indicator for HCC patients. AFP mRNA has been proposed as a predictive marker of HCC cells disseminated into the circulation and for metastatic recurrence. Many pathologic features,such as tumor size, number, capsule state, cell differentiation, venous invasion, intrahepatic spreading, and advanced pTNM stage, are the best-established risk factors for recurrence and important aspects affecting the prognosis of patients with HCC. Marked inflammatory cell infiltration in the tumor could predict a better prognosis. Clinical stage is still the most important factor influencing on the prognosis. Extratumor spreading and lymph nodal metastasis are independent predictors for poor outcome. Soma new predictive systems have recently been proposed. Different strategies of treatment might have significant different effects on the patients'prognosis. To date, surgical resection is still the only potentially curative treatment for HCC,including localized postoperative recurrences.Extent of resection, blood transfusion, occlusion of porta hepatis, and blood loss affect the survival and prognosis of HCC patients. Regional therapies provide alternative ways to improve the prognosis of HCC patients who have no opportunity to receive surgical treatment or postoperative recurrence. The combination of these treatment modalities is hopeful to further improve the prognosis. The efficacies of neoadjuvant ( preoperative ) or adjuvant ( postoperative )chemotherapy or chemoembolization in preventing recurrence and on the HCC prognosis still remain great controversy, and deserve further evaluation.Biotherapy, including IFN-alpha therapy, will play more important role in preventing recurrence and metastasis of HCC after operation. | Lun-Xiu Qin Zhao-You Tang,Liver Cancer Institute and Zhongshan Hospital,Fudan University,Shanghai,China | 2002 | World Journal of Gastroenterology2002,8,2: | 77 |
| 18 | Vascular endothelial growth factor and microvascular density in esophageal and gastric carcinomas显示文摘AIM: To observe the relationship between the expression of vascular endothelial growth factor (VEGF), microvascular density (MVD) and the pathological characteristics of esophageal and gastric carcinomas.METHODS: S-P immunohistochemical staining was used to investigate the expression of VEGF in all the specimens.The antibody against factor VIII-related antigen was used to display vascular endothelial cells, and MVD was examined by counting the factor VIII-positive vascular endothelial cells.RESULTS: The positive rates of VEGF expression in esophageal carcinoma and gastric carcinoma were 81.36 %and 67.5 % respectively, and the MVD averaged 41.81±8.44and 34.36±9.67 respectively, which were higher than those in benign diseases. The expression of VEGF and MVD were closely correlated with the degree of differentiation, lymphatic metastasis, but not related to depth of cancer invasion. In early stage gastric carcinoma, the rate of expression of VEGF and MVD was lower than that in progressive gastric carcinomas. CONCLUSION: The expression of VEGF is correlated with tumor angiogenesis, and VEGF plays an important role in new blood vessels formation, the expression of VEGF and MVD play an important role in tumor growth and metastasis.MVD and the expression of VEGF may be two important indexes for patients′ prognosis. | Jin-Rong Du Ying Jiang Yan-Mei Zhang Hong Fu, Department of Pathology, the Second Affiliated Hospital, Harbin Medical University, Harbin 150086, Heilongjiang Province, China | 2003 | World Journal of Gastroenterology2003,9,7: | 75 |
| 19 | Prognostic significance of expression of cyclooxygenase-2 and vascular endothelial growth factor in human gastric carcinoma显示文摘AIM: To investigate the role of cyclooxygenase-2(COX-2)and vascular endothelial growth factor (VEGF) in the development of gastric carcinoma and correlation between expression of COX-2 and VEGF and clinicopathologic features in tissues from patients with gastric carcinoma.METHODS: 281 patients with gastric carcinoma who underwent surgical resection between 1990 and 1999 at the First Affiliated Hospital, Anhui Medical University, PRC, were followed up. Expression of COX-2 and VEGF was investigated retrospectively in 232 gastric carcinoma tissues and 60noncancerous specimens by using immunohistochemistry.RESULTS: The 5-year survival rates of early gastric carcinoma (EGC) and advanced gastric carcinoma (AGC) were 93.4 %and 59.0 %, respectively. Survival time was highly correlated with lymph node metastasis, vascular invasion, depth of invasion and treatment with chemotherapy. Compared with paired noncancerous tissues, expression of COX-2 and VEGF and microvessel density (MVD) value in carcinoma tissue were significantly higher. The MVD value was much higher in COX-2-positive group and VEGF-positive group than that in COX-2-negative group and VEGF-negative group.Expression of COX-2 and VEGF, as well as MVD value were highly correlated with lymph node metastasis and vascular invasion. The 5-year survival rate of patients with expression of COX-2 or VEGF was significantly lower than that of patients without COX-2 or VEGF expression. Multivariate analysis revealed that VEGF overexpression, lymph node metastasis,COX-2 overexpression, depth of invasion and vascular invasion were all independent prognostic factors of gastric carcinoma.CONCLUSION: Overexpression of COX-2 and VEGF in patients with gastric carcinoma can enhance the possibility of invasion and metastasis, implicating a poor prognosis.They may serve as the fairly good prognostic factors to indicate biologic behaviors of gastric carcinoma. | Hai Shi Jian-Ming Xu Nai-Zhong Hu Hui-Jun Xie Department of Gastroenterology,the First Affiliated Hospital,Anhui Medical University,Hefei 23022,Anhui Province,China | 2003 | World Journal of Gastroenterology2003,9,7: | 64 |
| 20 | Formalized therapeutic guideline for hyperlipidemic severe acute pancreatitis显示文摘AIM: To investigate a formalized therapeutic guideline for hyperlipidemic severe acute pancreatitis (HL-SAP).METHODS: Thirty-two consecutive patients with severe acute pancreatitis were included in the clinical trial. All of them met the following five criteria for admission to the study, namely the Atlanta classification and stratification system for the clinical diagnosis of SAP, APACHEII score more than 8, time interval for therapeutic intervention less than 72 hours after onset of the disease, serum triglyceride (TG) level 6.8 mmol/l or over, and exdusion of other etiologies.They were divided into severe acute pancreatitis group (SAP,22 patients) and fulminant severe acute pancreatitis group (FSAP, 10 patients). Besides the conventional therapeutic measures, Penta-association therapywas also applied in the two groups, which consisted of blood purification (adsorption of triglyceride and hemofiltration), antihyperlipidemic agents (fluvastatin or lipanthyl), low molecular weight heparin (fragmin), insulin, topical application of Pixiao (a traditional Chinese medicine) over the whole abdomen, serum triglyceride,pro-inflammatory cytokines and anti-inflammatory cytokines were determined before blood purification (PF), at the end of blood purification (AFE) and on the 7th day after onset of the disease (AF7) respectively. Simultaneously, severity of the diseases was assessed by the APACHE Ⅱ system.Prognosis was evaluated by non-operation cure rate,absorption rate of pseudocyst, time interval pseudocyst absorption, hospital stay and survival rate.RESULTS: Serum triglyceride level (mmol/L), TNFα (U/mi) concentration and APACHE Ⅱ score were significantly decreased (P<0.05) at AFE and AF7, as compared with PF.However, serum IL-10 concentration (pg/ml) was increased significantly (P<0.001) at AFE, and decreased significantly (P<0.05) at AF7 when compared with PF. Operations: The First surgical intervention time was 55.8±42.6 days in SAP group (5 patients) and 12.2±6.6 days in FSAP group (7 patients),there was a significant difference between the two groups (P=0.02). The number of operations in the two groups was 1.33±0.5 vs3.5±1.2 (P=0.0037), respectively. Prognosis: Nonoperation cure rate, absorption rate of pseudocyst, hospital stay and survival rate in SAP group and FSAP group were 100 % (22/22) vs11.1% (1/9), 77.3 % (17/22) vs 11.1%(1/9), 54.2±35.9 vs99.1±49.5 days (P=0.008) and 100 %(22/22) vs66.7 % (6/9) (P=0.0044). The time for absorption of pseudocyst was 135.1±137.5 days in SAP group.CONCLUSION: Penta-association therapy is an effective guideline in the treatment of hyperlipidemic severe acute pancreatitis at its early stage (within 72 hours). | En-Qiang Mao Yao-Qing Tang Sheng-Dao Zhang, Department of Surgery, Ruijin Hospital, Shanghai Second Medical University, Shanghai 200025, China | 2003 | World Journal of Gastroenterology2003,9,11: | 64 |
