ABSTRACT
Objective To observe the effect of different doses unilateral and compound of artesunate and ursolic acid on lipid metabolism in rats′model, find out the best ratio of artesunate and ursolic acid .Methods Lipid metabolism disorders model was in-duced by feeding high fat diet in rat .The best ratio was screened through comparing the lipid level of rats ofdifferent groups .Results The results showed that Artesunate ( high dose ) +Ursolicacid ( high dose ) significantly reduced TG , CHO and LDL-C, increased HDL-C and H/L.Lipid-lowering effect was superior the positive drug fenofibrate , but also superior to the same dose of artesunate and ursolic acid alone.No significant effect of each test sample on the rat liver function was observed (P>0.05).Conclusion Artesunate and ursolic acid ratio of 1:1 had the best lipid-lowering effect, and the recommended dose was (50+50) mg/kg.
ABSTRACT
Objective To explore the influence of structured lipid emulsion on acute phase protein and acute inflammatory reaction in gastrointestinal cancer patients after operation.Methods Eighty postoperative patients with gastrointestinal caner from July 2010 to February 2012 were randomly divided into observation group and control group,and 40 cases for each group.Patients in observation group were given structured lipid emulsion,while in control group were given physic mixture of medium-chain/long-chain triglycerides group.Meanwhile patients in both groups were received isonitrogenous and isocaloric parenteral nutrition for 6 days after operation.The general conditions after operation were recorded.Acute phase protein and acute inflammatory reaction were measured before operation,the 1 st day and 7th day after operation.Results After 6 days parenteral nutrition,the vital sign data,blood routine indices,liver and renal function,blood fat were back to normal values in two groups.There was no significant difference in the incidence of postoperative infection complication and hospitalization duration between observation group and control group (12.5％ (5/40) vs.25.0％ (10/40) ; (12.9 ± 0.7) d vs.(13.1 ± 0.9) d; P ＞ 0.05).The serum levels of Albumin (ALB),Prealbumin(PAB) and Transferrin(TRF) on the 1st day after operation in two groups were significantly lower than those before operation,while the serum levels of C reactive protein (CRP) and fibrinogen (Fib) were significantly higher,then gradually recovering.The serum levels of ALB,PAB,TRF,CRP,Fib on the 7th day after operation in observation group were (37.11 ± 3.30) g/L,(0.25 ± 0.08) g/L,(2.35 ± 0.49) g/L,(21.84±16.76) mg/L,(3.95 ± 1.23) g/L,significant different from those on the 1st day before nutrition therapy ((31.52±2.92) g/L,(0.15 ±0.02) g/L,(1.90 ±0.54) g/L,(83.80 ±47.13) mg/L,(4.35 ±0.98) g/L) and control group ((34.50 ±2.71) g/L,(0.18 ±0.05) g/L,(2.00 ±0.52) g/L,(41.36 ±23.49) mg/L,(4.76 ± 2.35) g/L; P ＜ 0.05).The serum levels of interleukin (IL)-1,IL-2,IL-6,tumor necrosis factor (TNF)-α decreased on the 1st day after operation of two groups,then gradually increasing.The serum levels of IL-2,IL-6 on the 7th day after operation in observation group were (987 ±203) ng/L) and (277 ± 107) ng/L,significant different from those on the 1st day before nutrition therapy ((890 ± 197) ng/L and (355 ± 107) ng/L;P ＜0.05),and lower than those in control group ((1 347 ± 195) ng/L,(752 ± 187) ng/L; P ＜0.05).The serum levels of TNF-α on the 7th day after operation in observation group was (197 ±98) ng/L,which was as same as that on the 1 st day before nutrition therapy ((167 ± 79) ng/L,P ＞ 0.05) and lower than this in control group((342 ± 106) ng/L;P ＜0.05).Conclusion Structured lipid emulsion can effectively improve the synthesis of acute phase protein in gastrointestinal cancer patients after operation,regulate the inflammatory cell factors producing and releasing,which is benefit to smoothly through stress reaction period.
ABSTRACT
Objective To explore the influence of structured lipid emulsion on inflammatory cell factors and immunologic function in gastrointestinal cancer patients after operation.Methods From July 2010 to February 2012,80 postoperative patients with gastrointestinal cancer were randomly divided into 2 groups with 40 cases each by stratified sampling method:structured lipid emulsion group (observation group),physical mixture of medium-chain/long-chain triglycerides group (control group).Both groups received isonitrogenous and isocaloric parenteral nutrition for 6 days after operation.The general conditions after operation were compared between two groups.Inflammatory cell factors and immunologic function were measured before operation,the 1st day and 7th day after operation.Results After 6 days parenteral nutrition,the vital sign data,blood routine,liver and renal function,blood fat etc was normal in two groups.There was no significant difference in the incidence of postoperative infection complication and hospitalization duration between observation group and control group [12.5％(5/40) vs.25.0％(10/40),[( 12.9 ± 0.7 d) vs.(13.1 ±0.9) d] (P ＞0.05).The serum levels of interleukin (IL)-1,IL-2,IL-6,tumor necrosis factor (TNF)-α on the 1st day after operation in two groups decreased,then gradually increasing.The serum levels of IL-2,IL-6,TNF- α on the 7th day after operation in observation group[(987 ± 203),(277 ± 107),( 197 ± 98) ng/L] were lower than those in control group [(1347 ± 195),(752 ± 187),(342 ± 106) ng/L](P＜0.05 ).The serum levels of IgG,IgA,IgM,CD3+,CD4+ and CD8+ on the 1st day after operation in two groups decreased,then gradually increasing.The serum levels of IgG,CD3+,CD4+ were higher in observation group [( 14.2 ± 1.8 ) g/L,0.746 ± 0.111,0.580 ± 0.067] than those in control group [( 12.1 ± 2.8) g/L,0.606 ±0.101,0.404 ± 0.072] (P ＜0.05).Conclusion Structured lipid emulsion can reduce immunological suppression and inflammation in gastrointestinal cancer patients after operation,regulate the inflammatory cell factors producing and releasing,improve the immunologic function.
