This article was aimed to study the intestinal absorption about main active ingredients of pectolinarin and pectolinarigenin in Carboned Cirsium japonicum DC. The absorption rate and absorption rate constant were taken as indicators. The intestinal absorption of pectolinarin and pectolinarigenin were compared by everted rat intestinal sac method among different parts of the small intestine. The results showed that the absorption rate constant of pectoli-narin among duodenum, jejunum, ileum and colon parts were 0.505 1 ± 0.192 7, 0.936 0 ± 0.187 2, 0.732 0 ±0.133 5, 0.251 3 ± 0.027 6 (μg·h-1·cm-2). The absorption rate constant of pectolinarigenin among the duodenum, je-junum, ileum and colon were 0.059 1 ±0.008 3, 0.093 3 ±0.029 2, 0.112 3 ± 0.035 6, 0.029 4 ± 0.009 1 (μg·h-1·cm-2). It was concluded that the absorption of both ingredients increased over time. The absorption of both ingredi-ents in the jejunum and ileum was higher than other parts of the small intestine. The absorption rate of pectolinarin in the entire small intestine was much higher than the absorption rate of pectolinarigenin.

Objective To explore any effect of calorie restriction on the proliferation of satellite cells in the skeletal muscles of elderly rats.Methods Twelve male C57BL rats aged 12 or 13 months were randomly divided in to an experimental group and a control group,each of 6.The control group was fed 75.09 kJ/d as normal,while the experimental group was provided with 45.05 kJ/d (60％ of normal).The intervention lasted for 15 weeks and each rat's weight was measured every week.After the intervention,limb muscle satellite cells were sorted by fluorescenceactivated cell sorting after digestion,and the cell cycle was analyzed.Western blotting was used to assess the expression of cyclin A,D1 and E.Results There was no significant difference in the average weight of the two groups before the experiment.After the 15 weeks the average weight of the experimental group had decreased significantly (to 19.5±0.4 g),and it was significantly lighter than that of the control group (31.9±0.5 g).The average percentage of the satellite cells in the G0/G1 phase had decreased significantly in the experimental group,but the percentage in the S phase had increased significantly.The expression of cyclin A and E was significantly greater in the experimental group compared with the control group,but the expression of cyclin D1 had decreased significantly.Conclusion Caloric restriction can delay the proliferation of satellite cells in the skeletal muscles of elderly mice.

Objective To investigate the killing effect of hematoporphyrin derivative photedynamic therapy (PDT) on cultured human pancreatic cancer cell,and to explore the mechanism of this effect.Methods Biolitec PDT 630 semi-conductor laser therapeutic apparatus was used as the light source.After pancreatic cancer cell PANC1 was incubated 8 h with different concentrations of Photosan(hematoporphyrin derivative) as photosensitizer (0.5mg/L,1 mg/L,2 mg/L,4 mg/L),the cells were given different doses of 630nm laser irradiation(1 J/cm2' 5 J/cm~2,10 J/cm~2 ).The A492 value was determined in each group with MTT method.Cell apoptosis rate was detected by flow cytometry after PDT.Results There was no killing effect when no Photosan was administrated;10 J/cm~2 irradiation had killing effect on PANC1 when Photosan was administrated as 1 mg/L(0.140±0.013 vs 0.213±0.008,P＜0.05);5 and 10 J/cm~2 irradiation all had killing effect on PANC1 when Photosan was administrated as 2 mg/L (0.081±0.024 and 0.049±0.013vs 0.211±0.031,P＜0.05 and P＜0.01 );all doses of irradiation had killing effect when Photosan was administrated as 4 mg/L.There was no significant difference between 5 and 10 J/cm~2 irradiation in term of killing effect.Cell apoptosis rates with 0 or 2 or 4 mg/L Photosan and 10 J/cm~2 irradiation were(13.8±1.8) %,(40.9±1.6)%,(62.5±2.0)%,the difference was statistically significant(P＜0.05).Conclusions Photosensitizer or irradiation alone did not produce PDT effect.With certain dose of photosensitizer and irradiation,the PDT effect increased accordingly.
