Objective To study the protective effect and mechanism of Inonotus obliquus polysaccharide on liver injury induced by isoniazid( INH) combined with rifampicin( RFP) in mice. Methods Forty-eight mice were randomly divided into six groups ( control, model, huganpian, Inonotus obliquus polysaccharide at low, middle, and high dose ) . The mice were administered orally with isoniazid and rifampicin simultaneously except the control. After 2 h,the control and model groups were administered with normal saline,and others were treated with huganpian and Inonotus obliquus polysaccharide,respectively,once a day for 2 weeks. The liver index and serum levels of ALT and AST,malondialdehyde(MDA),superoxide dismutase(SOD) and glutathione peroxidase( GPx) were measured. Pathology examination of liver tissue was performed. Results The activities of ALT and AST, liver index, content of MDA in liver homogenate of mice treated with Inonotus obliquus polysaccharide and huganpian decreased obviously, while the liver SOD activity increased. Histopathological exzamination showed that Inonotus obliquus polysaccharide alleviated the degeneration and necrosis of hepatic cells. Conclusion Inonotus obliquus polysaccharide shows protective effects on mice with hepatic toxic injury induced by isoniazid and rifampicin,which maybe due to its antioxidation effect.

Objective To investigate the anti-inflammatory and analgesic activities of different extracts from X. mongolicum compared with that of X. sibiricum. Methods Seventy male Kunming mices were randomly divided into seven groups:control group,aspirin group,the ethanol extracts of X. sibiricum group and X. mongolicum group,the extracts from X. mongolicum with ether,ethyl acetate,and n-butyl alcohol group(n=10 each). The mice were administrated with 500 mg·kg-1 ( p. o. ) of different extracts. The hot-plate tests and the xylene-induced ear edema in mice were performed to observe the analgesic and anti-inflammatory activities,respectively. Results In the hot-plate tests,the pain threshold from the extracts of X. sibiricum and the different extracts from X. mongolicum at 60,120,180 min were prolonged,and there was no statistically significant differences(P>0. 05) between the ethanol extracts from X. sibiricum and X. mongolicum. The best analgesic activity was the ether and butyl alcohol extracts from X. mongolicum. Meanwile,the ear edema from the extracts of X. sibiricum and the different extracts of X. mongolicum were inhibited significantly(P<0. 05). There was also no significant differences between the ethanol extracts of X. sibiricum and X. mongolicum(P>0. 05). The ether and butyl alcohol extracts from of X. mongolicum showed the best anti-inflammatory effect. Conclusion X. mongolicum exhibites significant anti-inflammatory and analgesic activities comparable to that of X. sibiricum. The best anti-inflammation and analgesic activities were from ether and butyl alcohol extracts from X. mongolicum.

Objective To investigate the effect of acteoside on injury PC12 cells induced by glutamate. Methods PC12 cells were assigned into normal control group, model control group, positive drug group and acteoside(AS) treated group. Every group was treated by 1. 5 mmol·L-1 glutamate for 24 hours except for the control group, and the injury was antagonized by 10 μmol·L-1 Vit E and acteoside at different concentration(15. 625, 31. 25, 62. 5, 125 and 250 μmol·L-1 ). Cell morphology was observed by inverted microscope, cell survival was determined with MTT, LDH activity was measured by enzyme label kit, the MDA content and SOD activity were measured by TBA kit and WST kit, and the ROS was measured by Elisa kit. Results Compared with the model control group, all doses of acteoside could significantly improve the PC12 cell morphology and survival (P<0. 05), inhibit LDH activity and production of MDA and ROS (P<0. 05), increase the activity of SOD (P<0. 05), except for the lowest dose group.

Herald of Medicine.2015;(3):289-293. doi:10.3870/yydb.2015.03.002

Objective To study the therapeutic effects and related mechanism of Tongmai Yizhi granules on vascular dementia in rats. Methods Bilateral carotid artery ligation was used to establish rat model of vascular dementia (VD). The rats were randomly divided into 6 groups: sham operated,the model control,piracetam (0. 375 g·kg-1 ·d-1 ) as positive con-trol,low dose (2. 5 g·kg-1 ·d-1 ),middle dose(5. 0 g·kg-1 ·d-1 ),and high dose (10. 0 g·kg-1 ·d-1 ) of Tongmai Yizhi granules. Each group was intragastrically administered with 10 mL·kg-1 of corresponding medications for 31 days after the VD model was established. The sham group was given with 0. 9% NaCl solution. Y-electric maze was used to test the learning and memory function of rats at the second and fourth weeks. On the day 32,hippocampal tissues were collected for pathological analy-sis by microscope. The activities of SOD and content of MDA in serum and tissue homogenate were tested. Results Compared with model control group,each dose of Tongmai Yizhi granules obviously shortened the incubation period of VD rats in electric maze test,and accuracy of learning and memory was improved (P<0. 05 or P<0. 01). The activity of SOD was decreased,and the content of MDA was increased after treatment with Tongmai Yizhi granules (P < 0. 01). Hippocampal neuronal cells were disar-ranged,and the number of cone cells was decreased significantly in the model control group. In contrast,the necrosis and degener-ation of hippocampal neurons were alleviated in all Tongmai Yizhi treatment groups. Conclusion Tongmai Yizhi granule can apparently improve learning and memory function of VD rats. It can also improve the activity of SOD and reduce the content of MDA in serum and hippocampus,effectively remove free radicals,and alleviate the injury of hippocampal pyramidal cells.

Herald of Medicine.2015;(3):285-289. doi:10.3870/yydb.2015.03.001

Objective To study the effects of medicated serum with total saponins from Rhizoma Dioscreae Nipponicae (RDN) on VEGF mRNA expression and AP-1 activity in rat synovial cell strain RSC-364 induced by IL-17 and TNF-α. To investigate the mechanism about total saponin from RDN inhibition of angiogenesis. Methods Medicated serum of total saponins from RDN and tripterygium (positive control) were prepared. Rat synovial cells RSC-364 were divided into four groups: the blank control,IL-17+TNF-α model,tripterygium medicated serum,and total saponins medicated serum groups. After one hour of incubation,all groups except for the blank control were incubated with both IL-17(10 μg·L-1 ) and TNF-α(10 μg·L-1 ) for 24 hours. VEGF mRNA expression in RSC-364 was detected by PrimeScriptTM real-time quantitative PCR (RT-PCR) detection kit,and the AP-1 DNA-binding activity was detected by electrophoretic mobility shift assay (EMSA). Results Compared with the control blank group,both of the VEGF mRNA expression and AP-1 activity in rat synovial cell strain RSC-364 induced by IL-17 and TNF-α increased remarkably (P<0. 05,P<0.01). The VEGF mRNA expression and AP-1 activity in tripterygium medicated serum group and total saponins medicated serum group were remarkably lower than those of the model control group (P<0.05). There was no significant difference between the two medicated serum groups. Conclusion Serum medicated with total saponins from RDN can remarkably decrease VEGF mRNA expression and AP-1 activity,indicating that the total saponins from RDN could influence VEGF secretion by inhibiting the AP-1 signal transduction pathway,VEGF is the key factor of angiogenesis,thereby to restrain angiogenesis.

Objective To establish a method for determining cinnamic aldehyde content in Xianggui Huazhuo capsules by gas chromatography-mass spectrometry (GC-MS). Methods The content of cinnamic aldehyde was determined by GC-MS. Separation was performed on a capillary column (30 m×0. 25 mm, 0. 25 μm) with HP-5 as the stationary phase. A programmed temperature was employed. The flow rate was 1 mL·min-1 with He as carrier gas, and split ratio was 50∶1. The injection volume was 1. 0 μL. Results The cinnamic aldehyde was well isolated from the other ingredients. A good linear relationships of cin-namic aldehyde in range of 0. 02-4. 00 mg·mL-1 was observed. The correlation coefficient was 0. 999 4. The average recovery of cinnamic aldehyde was 96. 2% , and RSD was less than 2. 11% . Conclusion The method is simple, accurate and suitable for determination of cinnamic aldehyde content.
