[Objective] To investigate the mechanism of Dachengqi Decoction (DCD) in treating systemic inflammatory response syndrome ( SIRS). [ Methods ] Mouse models induced by zymosan A were administered with DCD orally. Serum endotoxin level was detected by limulus assay and TNF-? and IL-6 levels by radioimmunoassay 6, 12 and 24 hours after medication. [Results] Serum levels of endotoxin, TNF-? and IL-6 were increased in SIRS mice. After treatment with DCD, serum endotoxin level was decreased at the 6th and 12th hour ( P

Objective: To study the technological parameters of the purification process of ginsenosides with macroreticular resin. Methods: The adsorptive characteristics and elutive parameters of the process were studied by taking the elutive and purified ratio of ginsenosides as marker. Results: 45ml of the extractive of ginseng (5.88mg/ml) was purified with a column of macroreticular resin (R15mm?H90mm, dried weight 2.52g) and washed with 100ml of distilled water, then eluted with 100ml of 50% ethanol. Conclusion: With macroreticular resin to adsorb and purify, the elutive ratio of ginsenosides was above 90% and the purity reached 60.1%. So this process of applying macroreticular resin to adsorb and purify ginsenosides is feasible.

Objective To find out the distribution of the normal rating dactylogram of the juveniles of the She Nationality. Methods According to living body measure need, Prussian blue was used. Result Each type of dactylogram in number was as follows: LU>WS>WD>AT>AS. Ridgs count of each finger in quantitative order:thumb>ring finger>middle finger>index finger>little finger. Conclusion The rate of appearance of normal finger prints in various nationalities and regions has obvious difference, the normal rating of the dactylogram of the juveniles of the She Nationality differs from that of the local juveniles of the Han nationality.

Objective To explore the antitumor mechanism of xianhe yanling recipe( XHYLR ). Methods The mechanism of action of 241 compounds contained in the Chinese medicine, XHYLR was studied by using computational pharmacological. Methods including molecular docking,biotechnology network,chemical space technology and the prediction of absorption,distribution,metabolism,excretion and toxicity( ADME/T). Results Most of the compounds in XHYLR had good drug-like properties. Distribution of 241 compounds in chemical space also revealed that these compounds showed similar anti-tumor activity. It suggested that the prescription of XHYLR was reasonable. The phenomena that one molecular interacted with multiple target proteins and several molecules interact with one target protein were observed in XHYLR. For example,the COX-2 interacted with 40 micromolecules,and catechin interacted with five targets including COX-2. Conclusion These results are helpful for understanding the complicated mechanism of anti-tumor activity of XHYLR.

【Objective】The effect of sinomenine on human cyclo-oxygenase(COX) and interleukin-1?(IL-1?) was observed to explore the anti-inflammatory mechanism of sinomenine.【Methods】Peripheral blood monocytes(PBMC) were isolated and incubated with sinomenine.After incubation,total RNA from PBMC was extracted and the effect of sinomenine on COX and IL-1? expression with or without the stimulation of lipopolysaccharide(LPS) was observed by the method of semi-quantitative reverse transcription polymerase chain reaction(RT-PCR).【Results】Sinomenine had no effect on COX-1 gene expression,had a slight inhibitory effect on COX-2 gene expression and had a strong inhibitory effect on IL-1? gene expression.【Conclusion】 The anti-inflammatory mechanism may be related to the inhibition of inflammatory cytokines.

Objective To observe the effect of naringin on proliferation and differentiation of 3T3-L1 preadipocyte,and to investigate its possible mechanism.Methods The cultured 3T3-L1 cells were pretreated with naringin,and then MTT method was used to detect the proliferation of the cells,oil red O staining method and spectrophotography were applied to analyze the degree of differentiation.The expression of PPAR? 2 and C/EBP? mRNA associated with adipocytes differentiation were detected by reverse transcription PCR(RT-PCR).Results Naringin suppressed the proliferation and differentiation of 3T3-L1 preadipocytes and down-regulated the expression of PPAR? 2 and C/EBP? mRNA.Conclusion Naringin can inhibit the proliferation of 3T3-L1,and can suppress their differentiation through down-regulating the expression of PPAR? 2 and C/EBP? mRNA.

Objective To study the quality standard of Jinyou Tankeqing Tablets (JTT). Methods Total flavonoids in JTT were identified by TLC. Naringin content in JTT was determined by HPLC. Results The relevant spots of total flavonoids in JTT can be identified by TLC. The content of naringin in JTT can be determined by HPLC.
