Objective To study the inhibitory effect of Pharbitidis Semen on rat hepatoma induced by N-nitrosodiethylamine ( NDEA) . Methods SD rats were divided into normal control group, model control group and Pharbitidis Semen group. In model control group and Pharbitidis Semen group, 0. 01% NDEA was applied for 90 days to induce hepatoma, and rats in Pharbitidis Semen group concomitantly received feed containing 6% Pharbitidis Semen at the dosage of 40 g·kg-1 ·d-1 . Thirty days after the hepatoma inducement and Pharbitidis Semen administration, the rats were sacrificed to observe the pathological changes in liver, number of hepatoma nodules and liver weight. The changes of liver/body weight, serum alanine aminotransferase (ALT), γ-glutamyl transferase (γ-GT), and alkaline phosphatase (ALP) were compared. One-way ANOVA (LSD Test) was employed for statistical analysis. Results In the normal control group, the number of hepatoma nodules was 0. 0±0. 0, the liver weight was (9. 87±1. 30) g, the ratio of liver/body weight was (2. 62±0. 24)% and the level of serum ALT was (64. 10±12. 71) U·L-1,γ-GT was (0. 80± 0. 42) U·L-1, and ALP was (121. 20±37. 57) U·L-1. In the model control group, the number of hepatoma nodules was (27. 4±9. 5), the liver weight was (21. 38±7. 29) g, the ratio of liver/body weight was (5. 82±2. 31)%, the level of serum ALT was (175. 70±48. 75) U·L-1, γ-GT was (41. 80±15. 38) U·L-1, and ALP was (200. 50±35. 78) U·L-1. In the Pharbitidis Semen group, the number of hepatoma nodules was (8. 6± 5. 3), the liver weight was (13. 91±3. 55) g, the ratio of liver/body weight was (3. 86±0. 76)% and the level of serum ALT was (113.10±45.35) U·L-1, γ-GT was (13. 40± 6. 15) U·L-1, and ALP was (155. 80±30. 26) U·L-1. The results showed that all indices of Pharbitidis Semen group were higher than those of the normal control group, and lower than those of the model control group (P<0. 01 or P<0. 05). Conclusion Pharbitidis Semen can reduce NDEA-induced injury to the liver cells, and inhibit the overgrowth of the hepatoma.

Objective To analyze the effect of a combined strategy of enteral nutrition in the prevention and treatment of patients with severe bum sepsis. Methods 46 cases were random divided into combined group (group C) and routine group (group R). Besides general supportive treatment,group C was treated with early enteral feeding (EEF) ,recombinant human growth hormone (rhGH) and gluta-mine (Gln), while group R was given general supportive treatment only. The plasma concentration levels of pre-albumin (PA) , C-reactive protein (CRP), procalcitonin (PCT) and tumor necrosis factora (TNFα) were measured immediately after hospitalization and postbum day (PBD)7, 14,28. Results The survival rate of group C was significantly higher than group R. The incidence of sepsis, the complication of heart and gastrointestin in group C was significantly lower than group R ( P < 0. 01 ~ 0.05). The days in hospitalization of group C was shorter than that of group R. Plasma PA levels was decreased in two groups and was markedly decreased in the group R( P < 0. 01 ~ 0.05). Plasma CRP, PCT and TNFαlevels were both increased in two groups and markedly increased in the group R ( P < 0.001 ~ 0.05). Conclusions We have shown that a combined method including rhGH, EEF, Gln and anisodamin can effectively reduce the morbidity and mortality rates of burn sepsis and improve prognosis.
