| 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 |

| 3 | Homotopic mapping solving method for gain fluency of a laser pulse amplifier显示文摘The model for gain fluency of a laser pulse amplifier is studied. Using the homotopic mapping method, firstly, the system of the original model is packed up standardization; secondly, introducing a homotopic mapping, taking the property of the mapping, inducing a contrived parameter, the solving of a nonlinear problem translates into the solving of a linear problem. Then the approximate expressions of the solution for the corresponding model are obtained. And the precision for the approximate solution is compared. It illuminates that the obtained approximate solution using the homotopic mapping method possesses higher approximate degree. At one time, the expansion of solution through the homotopic mapping method can be kept in the analytic operation. Thus it also enables us through differential and integral operations to obtain other physics behavior for the gain fluency of laser pulse amplifier. | MO JiaQi1,2 1 Anhui Normal University, Wuhu 241000, China 2 Division of Computational Science, E-Institutes of Shanghai Universities, at SJTU, Shanghai 200240, China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 124 |

| 6 | 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 |

| 8 | 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 |
| 9 | 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 |
| 10 | Modulation of postoperative immune and inflammatory response by immune-enhancing enteral diet in gastrointestinal cancer patients显示文摘AIM To evaluate if the administration of anenteral diet supplemented with glutamine,arginine and ω-3-fatty acids modulatesinflammatory and immune responses aftersurgery.METHODS A prospective randomized double-blind, clinical trial was performed. Forty-eightpatients with gastrointestinal cancer wererandomized into two groups, one group wasgiven an isocaloric and isonitrogenous standarddiet and the other was fed with the supplementeddiet with glutamine, arginine and ωo-3-fattyacids. Feedings were started within 48 hoursafter operation, and continued until day 8. Allvariables were measured before operation andon postoperative day 1 and 8. Immune responseswere determined by phagocytosis ability,respiratory burst of polymorphonuclear cells,total lymphocytes lymphocyte subsets, nitricoxide, cytokines concentration, andinflammatory responses by plasma levels of C-reactive protein, prostaglandin E2 level.RESULTS Tolerance of both formula diets wasexcellent. There were siagnificant differences inthe immunological and inflammatory responsesbetween the two groups. In supplementedgroup, phagocytosis and respiratory burst aftersurgery was higher and C-reactive protein levelwas lower (P<0.01) than in the standard group.The supplemented group had higher levels ofnitric oxide, total Iymphocytes, T lymphocytes,T-helper cells, and NK cells. Postoperativelevels of IL-6 and TNF-α were lower in thesupplemented group ( P < 0.05).CONCLUSION It was clearly established in thistrial that early postoperative enteral feeding issafe in patients who have undergone majoroperations for gastrointestinal cancer.Supplementation of enteral nutrition withglutamine, arginine, and ω-3 fatty acidspositively modulated postsurgicalimmunosuppressive and inflammatoryresponses. | Guo Hao Wu Yan Wei Zhang Zhao Han Wu Department of General Surgery.zhongshan Hospital,ShangHai Medical University.ShangHai 200032.China | 2001 | World Journal of Gastroenterology2001，7，3： | 67 |
| 11 | 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 |

| 13 | 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 |
| 14 | 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 |
| 15 | Hepatocellular carcinoma with obstructive jaundice: diagnosis, treatment and prognosis显示文摘Obstructive jaundice as the main clinical feature is uncommon in patients with hepatocellular carcinoma (HCC). Only 1-12 %of HCC patients manifest obstructive jaundice as the initial complaint. Such cases are clinically classified as 'icteric type hepatoma', or 'cholestatic type of HCC'. Identification of this group of patients is important, because surgical treatment may be beneficial. HCC may involve the biliary tract in several different ways: tumor thrombosis, hemobilia,tumor compression, and diffuse tumor infiltration. Bile duct thrombosis (BDT) is one of the main causes for obstructive jaundice, and the previously reported incidence is 1.2-9 %.BDT might be benign, malignant, or a combination of both.Benign thrombi could be blood clots, pus, or sludge.Malignant thrombi could be primary intrabiliary malignant tumors, HCC with invasion to bile ducts, or metastatic cancer with bile duct invasion. The common clinical features of this type of HCC include: high level of serum AFP; history of cholangitis with dilation of intrahepatic bile duct; aggravating jaundice and rapidly developing into liver dysfunction. It is usually difficult to make diagnosis before operation, because of the low incidence rate, ignorant of this disease, and the difficulty for the imaging diagnosis to find the BDT preoperatively. Despite recent remarkable improvements in the imaging tools for diagnosis of HCC, such cases are still incorrectly diagnosed as cholangiocarcinoma or choledocholithiases. Ultrasonography (US) and CT are helpful in showing hepatic tumors and dilated intrahepatic and/or extrahepatic ducts containing dense material corresponding to tumor debris. Direct cholangiography including percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP)remains the standard procedure to delineate the presence and level of biliary obstruction. Magnetic resonance cholangiopancreatography (MRCP) is superior to ERCP in interpreting the cause and depicting the anatomical extent of the perihilar obstructive jaundice, and is particularly distinctive in cases associated with tight biliary stenosis and along segmental biliary stricture. Choledochoscopy and bile duct brushing cytology could be alternative useful techniquesin the differentiating obstructions due to intraluminal mass,infiltrating ductal lesions or extrinsic mass compression applicable before and after duct exploration. Jaundice is not necessarily a contraindication for surgery. Host patients will have satisfactory palliation and occasional cure if appropriate procedures are selected and carried out safely, which can result in long-term resolution of symptoms and occasional long-term survival. However, the prognosis of icteric type HCC is generally dismal, but is better than those HCC patients who have jaundice caused by hepatic insufficiency. | Lun-Xin Qin Zhao-You Tang Liver Cancer Institute and Zhongshan Hospital, Fudan University, Shanghai, China | 2003 | World Journal of Gastroenterology2003，9，3： | 68 |
| 16 | Preventive treatments for recurrence after curative resection of hepatocellular carcinoma-A literature review of randomized control trials显示文摘To review the inhibitory effect of preventive approaches on recurrence after operation in patients with hepatocellular carcinoma (HCC), we summarized all available publications. reporting randomized control trial indexed in PubMed. The treatment approaches presented above included preoperative transcatheter arterial chemoembolization (TACE),post-operative TACE, systemic or locoregional chemotherapy,immunotherapy, Interferons and acyclic retinoic acid Although no standard treatment has been established,several approaches presented promising results, which were both effective and tolerable in post-operative patients. Preoperative TACE was not effective on prolonging survivals,while post-operative TACE was shown with both diseasefree survival and overall survival benefits in some papers,however, it was also questioned by others. Systemic chemotherapy was generally not effective on prolonging survival but also poorly tolerated for its significant toxicities.Adoptive immunotherapy using LAK cells was proved to be beneficial to patients' survival in a recent paper. Interferon and Interferon β can inhibit recurrence in HCC patients with HCV infection background, though the mechanism is not fully understood. Acyclic retinoic acid was shown to decrease multi-centric recurrence after operation, which was reported by only one group. In conclusion, several adjuvant approaches have been studied for their efficacy on recurrence in HCC patients in randomized control trials; however, multi-centric randomized control trial is still needed for further evaluation on their efficacy and systemic or local toxicities;in addition, new adjuvant treatment should be investigated to provide more effective and tolerable methods for the patients with HCC after operation. | Hui-Chuan Sun Zhao-You Tang Liver Cancer Institute and Zhong Shan Hospital,Fudan University,Shanghai 200032,China | 2003 | World Journal of Gastroenterology2003，9，4： | 63 |
| 17 | Mesozoic subduction-accretion zone in northeastern South China Sea inferred from geophysical interpretations显示文摘A segment of Mesozoic subduction-accretion zone was inferred across the northeastern South China Sea at approximately NE45° orientation. Basic evidence includes the following: A belt of peek gross horizontal Bouguer gravity gradient (PGHGBA) is comparable in size and intensity to that of the Manila subduction-accretion zone. A belt of high positive magnetic anomalies appears to the north and sub-parallel to the PGHGBA, representing the volcanic arc associated to the subduction zone. The PGHGBA crosses obliquely both Cenozoic structures and present seafloor topography, indicating a pre-Cenozoic age. The segment is offset left-laterally by NW-running strike-slip faults, in concord with the Mesozoic stress field of South China. In addition, the existence of the subduction zone is supported by wide-angle seismic data obtained in different years by different institutions. At approximate localities, a north-dipping ramp of Moho surface is indicated by records of ocean-bottom seismometers, and a strong reflector about 8 km beneath the Moho reflector is indicated by both OBS and long-cable seismic records. The identification of a segment of Mesozoic subduction zone in NE South China Sea fills nicely the gap of the Great Late Mesozoic Circum SE Asia Subduction-acrretion Zone, which extended from Sumatra, Java, SE Kalimantan to N Palawan, and from Taiwan, Ryukyu to SW Japan. | ZHOU Di1, WANG Wanyin2, WANG Jialin3, PANG Xiong4, CAI Dongsheng5 & SUN Zhen1 1.

| 19 | Effects of time interval for hemofiltration on the prognosis of severe acute pancreatitis显示文摘AIM: To evaluate the impact of time interval for hemofiltration(HF) on the prognosis of severe acute pancreatitis (SAP).METHODS: Thirty-six consecutive patients with severe acutepancreatitis were included in the study. Atlanta classificationsystem was applied for stratification. They were randomlydivided into short veno-venous HF group, (SWH, Group 1,20 patients); and long veno-venous HF group (LWH, Group2, 16 patients). In group 1, SWH was stopped when theabdominal signs disappeared, and heart rate and breathrate were less than 90 leats/min and 20 times/min,respectively. HF was stopped if SWH was continued, andwhen heart rate and breath rate were more than 90 beats/min and 20 times/min again (Group 2). Except that the timeinterval for HF was different, other parameters for HF werethe same. And conservative curing rate, survival rate, costfor hospital stay and length of hospital stay were observed.RESULTS: Time interval for HF in Group 1 (3.81±1.3 hr)was shorter than that of in Group 2 (9.38+2.9hr), P<0.01.Conservative curing rate (90 %) in Group 1 was much higherthan that in Group 2 (56.3 %) (P<0.05); but cost in Group 1(RMB 56 600±56 400 Yuan) was lower than that in Group 2(RMB 137 000±105 000 Yuan) (P<0.05). And the survival rate(95 %) in Group 1 was higher than that in Group 2 (81.3 %)(P<0.25); however, hospital stay in Group 1 (44.3±41 days)was shorter than that in Group 2 (55.2±39.5 days) (P<0.2).So, the prognosis was not improved through the prolongationof time interval for HF, but side-effects were seen.CONCLUSION: The prognosis was not further improvedby LWH in the treatment of SAP, with side-effects. Timeinterval for HF plays an important role in treatment of SAPin early stage. SWH is thought to be superior to LWH; andLWH is superior to CVVH in early (72hrs) treatment of SAP. | 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 Gastroenterology2003，9，2： | 56 |
| 20 | Get effective polyclonal antisera in one month显示文摘According to the traditional immunization procedure, after the first injection of the sample A (emulsion of aimed antigen and Freund's complete adjuvant) to immunize rabbit, successive injections of the sample B (emulsion of aimed antigen and Freund's incomplete adjuvant) were followed every 2-4 weeks. In general,high titer of the corresponding polyclonal antisera will be observed after 4-5 injections of sample B in 3-4months. This report presents a simply modified procedure that was able to stimulate the antisera formation in one month and achieve enough avidity to satisfy either Western blot or immunohistochemistry analysis.It just applied an additional injection of the sample A to the rabbit at the 3rd day after the primary immunization injection. You could gain the high titer of the antisera right after the first sample B injection in one month. This method has produced the desired results in three different recombinant antigens with different molecular weight (5.9 KD-55 KD) expressed from prokaryotic or eukaryotic cells. | YUAN XIN HU, Ju YUAN QUO, Lu SHEN, YAN CHEN, Zu CHUAN ZHANG, YONG LIAN ZHANGState Key Laboratory of Molecular Biology, Institute of Biochemistry and Cell Biology, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, 320 Yue Yang Road, | 2002 | Cell Research2002，12，2： | 45 |
