OBJECTIVE: To observe the effects of Xinfeng Capsule (XFC), a compound Chinese herbal medicine, on behaviors and myocardial ultrastructure in adjuvant arthritis (AA) rats. METHODS: Fifty-five rats were randomly divided into normal control group, untreated group, methotrexate (MTX) group, Tripterygium wilfordii glycosides tablet (TGT) group and XFC group. There were 11 rats in each group. Except for those in the normal control group, the rats in the other groups were all intracutaneously given 0.1 ml Freund's complete adjuvant in the right hind limb. Changes of behaviors and myocardial ultrastructure of the rats in different groups were observed. RESULTS: Voix pedis' swelling and arthritis index in XFC, MTX and TPT groups were all obviously improved as compared with the untreated group. After XFC treatment, the autonomic activities were obviously increased, number of errors in exercise period and test period were obviously decreased, step-down latency (SDL) was lengthened and escape latency (EL) was shortened. Overall structure of myocardial myofibril and the majority of cristae was intact in XFC group. The effects of XFC in improving the behaviors and myocardial ultrastructure were better than those of MTX and TPT. CONCLUSION: Changes of behaviour and myocardial ultrastructure of AA rats can be observed. XFC can improve the myocardial ultrastructure of AA rats as well as their behaviors.

Objective To compare the expression of mIFN-γ, replicative activities and anti-tumor activities of CNHK300-mIFN-γand Ad-mIFN-γin normal and gastric cancer cells. Methods The replicative activities of viruses in cells were measured by viral replication assay. CPE assay was used to detect the antitumor effect of viruses. The expression level of mIFN-γ in cancer cells was detected by ELISA. Results The infection of CNHK300-mIFN-γled to an obvious expression of mIFN-γin gastric cancer cells. The vector system CNHK300-mIFN-γpossessed more replicated potential than Ad-mIFN-γ, and could specifically kill most of BGC-823 cells at MOI value of 0.1, which was much better than that by the traditional adenoviral vector. Conclusion CNHK300-mIFN-γcan selectively replicate and effectively express mIFN-γ in tumor cells, and specifically kill gastric cancer cells, suggesting a splendid future as a new anticancer agent.

Objective: To observe the effects of ginaton and nitroglycerin injection on expression of heat shock protein 70 (HSP70) and cardioprotective mechanism in rabbits with ischemia/reperfusion (I/R). Methods : Twenty New Zealand white rabbits were randomly divided into four groups, 5 rabbits being in each group. The model was not replicated in the sham-operated group. Myocardial I/R models were replicated in animals in normal saline, ginatone and nitroglycerin injection groups and were administered with normal saline, ginatone and nitroglycerin injection respectively 0.5 hour before ischemia. Western blot was used to measure HSP70 of ischemia and non-ischemia myocardium and the expression of HSP70 was analyzed semiquantitatively . Serum nitric oxide (NO), malondialdehyde (MDA) contents and total superoxide dismutase (TCD*2SOD) , creatine kinase (CK) activity were measured. Results: HSP70 was less expressed in sham-operated group and more expressed in normal saline group, ginaton group and nitroglycerin injection group. Expression of HSP70 of ischemia and non-ischemia myocardium in normal saline group was 2.5CD*2 and 2.1CD*2fold, in ginaton group 17.6CD*2 and 20.7CD*2fold and in nitroglycerin group 28.1CD*2 and 29.1CD*2fold to that in the shamCD*2operated group, respectively. The activity of TCD*2SOD was lower while MDA and CK levels were higher in the normal saline group than those in the sham-operated group (all P

The technique conditions of decolonization of fermentation broth were successively optimized using single factor assay and orthogonal layout method in Cordyceps jiangxiensis. The optimal condition of decolorization was investigated to be 3g/100mL active carbon, 5 min absorption time, pH5 of fermented broth and 25℃absorption temperature. Under the optimal condition, the maximum decolorization rate of fermented broth reached 89. 6% , simultaneously 10. 7% consuming rate of exopolysaccahride was minimum. Subsequently, the extract condition of exopolysaccharide of C. jiangxiensis was further optimized by orthogonal layout design. The maximum exopolysaccharide production was 0. 38 g/L under the optimal condition, i. e. firstly fermented filtrate decolorized and deproteined was concentrated to 1/7 of its total volume, secondly concentration broth was mixed with four times its volume of absolute ethanol and stirred vigorously, lastly precipitation of exopolysaccharide proceeded at 4℃for 16 hrs and the exopolysaccharide collected by centrifugal ion and dryness.
