ThemobilephaseAwas0.01mol·L-1potassi-um dihydrogen phosphate (adjusting pH to 2. 2 with phosphoric acid) and mobile phase B was acetonitrile with gradient elution,and the flow rate was 1. 0 ml· min-1 . The detection wavelength was 215nm,the column temperature was 40℃,and the injection volume was 20 μl. Results:The linear range of enalaprilat,enalapril maleate and eanlapril diketopiperazine was 14.64-43.92 μg·ml-1(r =0. 999 8), 9. 29-27. 87 μg·ml-1(r=0. 999 1)and 10. 80-32. 40 μg·ml-1(r=0. 999 5), respectively. Enalaprilat was not detec-ted out and enalapril diketone was 0. 2% using the method described in Chinese pharmacopeia, and the content of enalaprilat was 0. 1% and that of enalapril diketone was 0. 2% using the gradient elution. The related substances and enalapril maleate could be sepa-rated well. Conclusion:The method is sensitive, accurate and highly specific in the quality evaluation and control.

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.

A number of medications have been proved to be able to either improve the antitumor effect of chemotherapeutics and molecular targeted drugs or reverse the resistance of tumors to chemotherapeutics and molecular targeted drugs,which are not traditionally used as anticancer drugs.Especially for late-stage tumors after multiple treatments,these agents are good alternatives when used independently or in combination with chemotherapeutics and molecular targeted drugs.These drugs include proton modulators,hypoglycemic agents and cardiovascular agents,etc.

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.

Objective To determine the influence of viral factors and host cellular immunity on the response to interferon in the patients with chronic hepatitis C. Methods Forty patients with chronic hepatitis C were treated with interferon ?. The relationships between response to interferon a and HCV genotype, quasispecies heterogeneity, HCV RNA level and HCV specific cytotoxic T lymphocyte (HCV CTL) activity in the liver were analyzed. Results After 6 months of therapy, 21 patients had obtained end of treatment response (ETR), 10 Patients of which had obtained sustained response (SR). The other 19 patients got no response (NR). ETR rate in patients with genotype HCV1 infection (43.3%, 13/30) was significantly lower than that in patients with non HIV1 infection (80%, 8/10) [ P
