Objective To construct the plasmid that can produce long,double-stranded RNA and identify nonspecific apoptosis induced by long, double-stranded RNA in human osteosarcoma cells. Methods Plasmid pCI-neo-dsRNA was constructed by two promoters driven DNA sequence based on nontoxic, completely exoteric gene EGFP from the head and the end simultaneously to synthesize sense and antisense RNAs. Human osteosarcoma cells MG63 were transfected with pCI-neo-dsRNA and 48 h later the transfected cells were assessed by Apoptosis Detection System, FCMand MTT method. Results Plasmid pCI-neo-dsRNA was constructed successfully, MTT measurement showed that the absorbance of cells decreased gradually with the increase of plasmid pCI-neo-dsRNA dose(0.05 ?g, 0.10 ?g, 0.15 ?g, 0.20 ?g,0.25 ?g,0.30 ?g). MG3 transfected with pCI-neo-dsEGFP presented a great amount of irregular green fluorescence that indicated cell apoptosis. As the quantity of dsRNA increased, the percent of apoptosis cells also raised. While the dose of pCI-neo-dsEGF was 3.0 ?g, the apoptotic results of pCI-neo-dsEGF in MG3 were similar to that of 5-FU. Conclusion Long, double- stranded RNA could trigger human osteosarcoma cell apoptosis and the further research on using long, double-stranded RNA in osteosarcoma gene therapy can be done based on this theory.

Objective To study the role of Ginsenoside Re and Rb3 on mice with viral myocarditis (VMC) and explore the mechanisms. Methods BALB/C mice were infected by coxsackievirus B3 ( CVB3) to establish VMC model. The mice were divided into control group,virus group and Ginsenoside Re and Rb3 treatment group(treatment group). On day 5,day 10,day 20 after infection,the level of serum crea-tine phosphokinase-MB( CK-MB) was detected. Then myocardial sections stained with Masson′s trichrome were used to observe the distribution of mice myocardial collagen fibers, quantify collagen volume fraction (CVF),and detect the levels of superoxide dismutase(SOD). Results (1)The level of CK-MB peaked on day 5,and decreased afterwards[day 5:(463. 68 ± 47. 62) U/L; day 10:(588. 81 ± 56. 09) U/L; day 20:(340. 48 ± 58. 22) U/L,respectively]. While the levels of CK-MB in treatment group were lower than those in virus group[day 5:(378. 69 ± 56. 02) U/L;day 10:(452. 56 ± 67. 78) U/L; day 20:(327. 13 ± 47. 20) U/L,respectively] in the same point. There were significant differences between groups on day 5 and day 10 (P<0. 01). (2) In viral group,the blue staining degree gradually increased with time in myocardial sections stained with Masson′s trichrome,especially in myocardial necrosis area. Compared with treatment group,CVF increased significantly in virus group on day 10 and day 20 ( day 10:6. 52% ± 2. 34% vs. 8. 94% ± 1. 67%;day 20:7. 00% ± 1. 53% vs. 10. 46% ± 1. 74%,P<0. 01). The levels of SOD in myocardial sections in virus group were lower than those of control group[day 5:(48. 83 ± 17. 74) U/L;day 10:(61. 41 ± 14. 58) U/L;day 20:(66. 26 ± 18. 97) U/L,respectively,P<0. 05],but in treatment group,the level of SOD could beimprovedsignificantly[day5:(72. 07 ±24. 85)U/L;day10:(83. 22 ±19. 52)U/L;day20:(92. 00 ± 20. 46) U/L, respectively, P < 0. 05]. Conclusion Because of the inhibition of oxygen radicals and oxidative stress, Ginsenoside Re and Rb3 can protect myocardial tissue. Ginsenoside Re and Rb3 can effectively reduce the extent of myocardial fibrosis. The mechanism may be related with the reduced peroxide level in vivo.
