[Objective] To research the inhibitory effects of black garlic extracting solution on the growth of colon cancer Ht-29 through PI3 K /AKT signal pathway. [Method] The tumor-bearing C57 BL /6 mouse model was established. Mice were given different concentrations of black garlic extracting solutions and PI3 K inhibitor LY294002. At the end of the test,the tumors were peeled off and weighed to calculate the inhibitory rate of tumor growth. Akt protein expression was detected by immunohistochemistry. Bad and PTEN protein expression was analyzed by Western blot. And the expression of Caspase-9 was detected by Realtime-PCR. [Results] The tumor inhibitory rate of black garlic extracting solution on mice colon cancer reached 49. 93%. Black garlic extracting solution restricted the expression of Akt and p Bad,but enhanced the expression of PTEN,Bad and caspase-9. [Conclusions] Black garlic extracting solution might restrict the growth of colon cancer Ht-29 through PI3K / AKT signal pathway.
[Objective] To discuss the effects of Scutellaria bartata flavonoids on NOS,HSP70 and apo E expression of rats astrocytes induced by Aβ25- 35. [Methods] Astrocytes of rats in the third generation were randomly divided into blank control group,model group and three dosage groups of S. bartata flavonoids. 17. 5,35 and 70 μg / m L S. bartata flavonoids were added into cells in dosage groups for 24 h. Then,100 μmol Aβ25- 35 was added into model group and three dosage groups for reaction for 24 h. e NOS,i NOS and n NOS expressions in astrocytes were detected by immunohistochemistry. HSP70 and apo E mRNA expressions in astrocytes were detected by western blotting and RTPCR,respectively. [Results] Compared with blank group,e NOS content reduced by 60. 83%(P < 0. 01) in model group,i NOS content enhanced by 215. 03%(P < 0. 01),HSP70 content enhanced by 166. 67%(P < 0. 01),and apo E mRNA content increased by 150. 00%(P <0. 01). 17. 5,35 and 70 μg / m L S. bartata flavonoids enhanced the e NOS content in different degrees(73. 66%- 137. 77%,P < 0. 05),reduced the i NOS content by 19. 40%- 44. 50%(P < 0. 01),decreased the HSP70 content by 18. 52%- 49. 38%(P < 0. 01),and reduced the apo E mRNA content by 14. 17%- 41. 67%(P < 0. 01).

[Objective] To detect the 22 inorganic elements in " Zuota" grown in Tibet,Qinghai,Gansu and Sichuan Provinces of China; and to analyze their dissolution situation in artificial gastric fluid and artificial intestinal fluid. [Methods] After processed by microwave digestion and treated in artificial gastric fluid and artificial intestinal fluid,22 inorganic elements in " Zuota" were detected by ICP-OES method. [Results] The 22 inorganic elements in " Zuota" showed good linear relationship within the range of 0- 20 μg / m L(R2> 0. 999 4). Hg had the maximum content in " Zuota" among metallic elements. Total Hg had the maximum content in " Zuota" grown in Tibet,followed with Qinghai and Gansu. And total Hg content was the minimum in Aba of Sichuan. Most of the elements had higher dissolution rates in artificial gastric fluid than those in artificial intestinal fluid. Therefore,it could be concluded that the dissolution part in " Zuota" was mainly the stomach. [Conclusions] This method could detect many elements at the same time with wide linear range,which was rapid,accurate,simple and sensitive,and could be used for the detection of 22 inorganic elements in " Zuota".
