Objective To investigate the biological effects of nonthermal plasma (NTP) combined with X-ray irradiation on human hepatocellular carcinoma in nude mice.Methods By subcutaneous inoculation, tumor models of human hepatocellular carcinoma HepG2 in nude mice were established, and these mice were divided into control group, NTP treatment group, X-ray irradiation group, combined treatment group.The changes of tumor microenvironment were observed using hematoxylin-eosin (HE) staining.The terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) was used to determine the level of neuronal apoptosis in tumor tissues.The expression of metal matrix proteinase-2 (MMP-2) was detected by immunohistochemical assay.Transmission electron microscope was used to observe cell structure changes.Results The final tumor volumes of control group, NTP treatment group, X-ray irradiation group, combined treatment group were (543.96±108.45), (436.54±65.49), (351.66±56.68), (281.97±35.60)mm3, with a statistically significant difference (F=9.63, P=0.01), and the difference between X-ray radiation group and the combination treatment group was significant (P=0.05).HE staining showed that there was a larger area of necrosis in the combined treatment group compared with the other groups.TUNEL showed that the apoptotic indexes were (0.95±0.13)%, (5.82±0.26)%, (7.53±0.43)%, (11.07±0.35)% respectively, with a statistically significant difference (F=547.76, P=0.00), and the difference between X-ray radiation group and the combination treatment group was statistically significant (P=0.00).The immune scores of each group were 12, 9, 9, 2.Electron microscopic observation showed that there were more apoptotic bodies in the combined treatment group than those in the other groups, accompanied by mitochondrial edema.Conclusion NTP and X-ray irradiation therapy in the treatment of human hepatocellular carcinoma in nude mice model has a synergistic effect.Probably, it can be a new type of treatment in curing cancers.

Objective To explore the anti-hyperuricemia activity of bergenin in the model of hyperuricemic mice induced by potassium oxonate. Methods 60 Kunming male mice were divided randomly into six groups, which were normal control group;hyperuricemic model group;and hyperuricemic groups with 20 , 40 , 60 mg/kg berge-nin, and 5 mg/kg allopurinol. Mice were orally administered once daily with 250 mg/kg potassium oxonate for 7 continuous days to create the model, and then three doses of bergenin and allopurinol were orally initiated on the day 1 h after potassium oxonate was given, separately. Serum uric acid, creatinine and urea nitrogon levels, as well as urinary uric acid and creatinine levels were measured. mRNA and protein expression levels of mouse kidney u-rate transporter 1(URAT1), and glucose transporter 9(GLUT9) were also determined. Results Compared with hyperuricemic model group, bergenin significantly reduced serum uric acid, creatinine and urea nitrogon levels, in-creased 24 h uric acid and creatinine excretion, and fractional excretion of uric acid in hyperuricemic mice;mRNA and protein levels of mURAT1 and mGLUT9 were also markedly down-regulated. Conclusion Anti-hyperuricemia effect of bergenin is attributed to the enhancement of uric acid excretion and reversion of mouse urate transporters o-ver-expression.
