Objective To analyze the clinical features of acute hyperlipidemic panereatitis,and to investigate the therapeutic strategies.Methods In this retrospective study,44 patients with hyperlipidemic pancreatitis admitted to our hospital from January 2003 to December 2007 were enrolled,60 patients with acute pancreatitis of other etiologies were enrolled as the control group.Results The proportions of patients with overweight or obesity,hyperglycemia,fatty liver and hypertension were 81.8%,59.1%,54.5% and 68.2%,respectively;these were significantly higher than those in control group,which were 16.7%,16.7 %,13.3 % and 23.3 %,respectively (P＜0.05 or＜0.01).The proportion of patients with lithiasis was lower in HLP group than that in control group (13.6% vs 60.0%,P＜0.05).There was no difference in the proportions of patients with chronic alcoholism between two groups.The Ranson score,CTSI,complications in HLP group were 3.15±0.07,4.46±2.58 and 3.2±1.7,respectively;these parameters were significantly higher than those in control group,which were 1.62±0.22,2.62±1.90 and 0.9±1.2 (P＜0.05 or ＜ 0.01 ).The level of serum amylase in HLP group was 580±222 mmol/L,which was significantly lower than that of control group (1361±472 mmol/L,P ＜ 0.01 ).The triglyceride (TG) level was linearly correlated with Ranson score in HLP group ( r = 0.77,P ＜ 0.05 ),but there was no linear correlation between TG level and Ranson score in the control group.Conclusions There was a close relationship between HLP and metabolic syndrome.Serum TG was positively correlated with the severity of HLP.

Objective: To investigate the effect of tumor specific antigen of HCA520 on the proliferation of HEK293 cells and to obtain some functional implications for HCA520. Methods: MTT assay was performed with HEK293 stable cell lines transfected with pcDNA3-HCA520-flag construct. Cytokines probably involved in HCA520 enhanced proliferation were screened by RT-PCR, and effect of these cytokines on the HEK293 cell proliferation was further confirmed by MTT assay. Results: HCA520 significantly promoted the proliferation of HEK293 cells, which was at least partially attributed to the up-regulation of IL-6 in HEK293 cells by HCA520. Conclusion: HCA520 might accelerate tumorigenesis by promoting proliferation of cancerous cells.

Purpose:To detect the action of arsenic trioxide(As 2O 3) on the expression of tumor drug-resistant protein. Methods:APL cell line MR 2 resistant to all-trans retinoic acid(ATRA) was used for in vitro studies. APL cell line NB 4 was used for control. The expressions of P-glycoprotein(Pgp), multidrug resistance protein(MRP)were determined by immunocytochemical assays. Results:The expression of Pgp was significantly higher in MR 2 cell line(30%-40%) than in NB 4 cell line(10%-20%)(P

Purpose:To study the effects of hydroxycamptothecin with thermotherapy on anti-angiogenesis in vitro and in vivo. Methods:We chose human microvascular endothelial cell (HMVEC) culture and chick embryo choriallantoic membrane (CAM) model and used MTT and number-calculating methods to observe hydroxycamptothecine on HMVEC’s proliferation , sprouts and CAM blood vessels’ formation.Results:The survival rate of endothelial cells was in the range of (68.2%)-44.7% within the dose of 20-40 ng/ml and 5-80 ng/ml and was negatively correlated with the concentration (correlation coefficient was -0.906,-0.469,P=0.00003,0.0051). Hydroxycamptothecine could significantly suppress the endothelial cells’ proliferation and the sprouts. Hydroxycamptothecine could significantly suppress CAM vessels. The survival rate of HepG II cells is in the range 100%-90% within the dose of 5-80 ng/ml. There was no cytotoxicity.There was a synergestic anti-angiogenetic effect when hydroxycamptothecin (20 ng/ml) was combined with thermotherapy in vitro while there was additive effect when hydroxycamptothecin (40 ng/ml) was combined with thermotherapy in vitro.Conclusions:This experiment shows that small doses of hydroxycamptothecine (20-40 ng/ml) with thermotherapy has anti-angiogenetic synergestic or additive effect on proliferation and migration both in vivo and in vitro.

Background and purpose:The growth,metastasis,relapse and the prognosis of tumor are correlated with tumor angiogenesis.Therefore,target to angiogenesis and antiangiogenic therapy has become one of the hot points in cancer research field.Some chemotherapeutic drugs can inhibit the growth of new vascular endothelial cell markedly in the way of low-dose and high time administration.This is metronomic chemotherapy or antiangiogenic chemotherapy.Traditional Chinese medicine has an effect on tumor control.In recent years,we discovered that some traditional Chinese medicine have an antiangiogenic effect.This experiment aimed to study the antiangiogenetic ability of oxaliplatin combined with composite radix sophora flavescentis injection(CRSFI) in vitro and in vivo. Methods :We used MTT method to observe the influence of oxaliplatin and composite radix sophora flavescentis injection on human umbilical vein endothelial cells(HUVEC) or LoVo proliferation.The influence of oxaliplatin and composite radix sophora flavescentis injection on HUVEC migration was evaluated by transwell.Chick embryo chorioallantoic membrane(CAM)model was used to check whether the neovascularization of CAM could be suppressed in vivo by them. Results :The survival rate of LoVo within the same doses of oxaliplatin and composite radix sophora flavescentis injection were higher than HUVEC.Oxaliplatin(2 ?g/ml) and composite radix sophora flavescentis Injection(25 ?l/ml) could inhibit the prolifetation of HUVEC;the rate of inhibition were 31.6%,32.1% respectively;the rate of the two drugs combination was 54.4%.So when combined,they had synergistic effect.There was coordinate repression to migration of HUVEC in vitro when we used oxaliplatin(0.5 ?g/ml) and composite radix sophora flavescentis injection(6.25 ?l/ml).They also suppressed angiogenesis of CAM in vivo. Conclusions :This experiment showed that low dose oxaliplatin combined with composite radix sophora flavescentis injection has anti-angiogenic synergetic ability in vivo and the ability of inhibiting the growth of the cells in vitro.

We used retroviral vector pLXSN to construct recombinant retroviral vectors with the human apoptosis gene, interleukin-l? converting enzyme (ICE). The vectors were introduced into packaging cell line PA317 by electroporation method. The G418 resistant colonies were selected, and the supematants of the colonies were used to infect the human hepatocellular carcinoma cell line SMMC7721. G418 resistant colonies of SMMC7721 were named SMMC7721-MCE and SMMC7721-neo. The results of RT-PCR analysis showed that exogenous hICE gene had successfully integrated into the genome of SMMC7721-hICE cells. The proliferation rate and tumorigenicity of cells in nude mice were examined. Our data showed that the growth rate and the tumorigenicity of SMMC7721-hICE cells in nude mice were considerablely decreased comparing with parent SMMC7721 and SMMC7721-neo. These results suggested that the retroviral vector expressing hICE gene was successfully constructed and could suppress the growth ability and tumorigenicity of human hepatocellular carcinoma cells, which provided a basis for further investigation of hICE gene therapy.

Erythrocytes, the most abundant cells in human body with excellent physiologic and morphologic characteristics, have been exploited extensively for their potential applications as drug delivering microspheres for several potential applications, including intravenous slow release of therapeutic agents, enzyme replacement therapy and drug targeting therapy. A series of methods has been tested successfully for the improvement of targeting to reticuloendothelial system.
