OBJECTIVETo explore effects and action mechanism of warm moxibustion on regulation of blood lipids and anti-atherosclerosis.

METHODSForty-one male Japanese big-ear white rabbits were randomly divided into a blank group (10 rabbits), a model group (10 rabbits), a moxibustion group (10 rabbits) and a medication group (11 rabbits). Normal diet was applied in the blank group while high-cholesterol diet combined with injection of bovine serum albumin were applied in the rest groups to establish rabbit model of atherosclerosis. After establishment, the model group was not intervened and warm moxibustion was applied in the moxibustion group at "Zusan-li" (ST 36) and "Shenque" (CV 8), 10 min per acupoint per day for continuous 4 weeks. The medication group was treated with intragastric administration of lovastatin capsule (3.6 mg/kg) for continuous 4 weeks. The level of blood lipids, such as total cholesterol (TC), triglyceride (TG), and content of CD40 ligand (CD40L), soluble CD40 ligand (sCD40L) and expression of nuclear factor NF-kappaB were tested after 4 weeks.

RESULTSCompared with the model group, the moxibustion group and medication group could effectively reduce the contents of TC and low density lipoprotein (all P < 0.05), lower the level of sCD40L [(8.310 +/- 1.221) ng/mL in the model group, (7.097 +/- 0.846) ng/mL in the moxibustion group and (7.354 +/- 0.631) ng/mL in the medication group], reduce expression of CD40L [(0.235 +/- 0.179) mm2 in the model group, (0.072 +/- 0.079) mm2 in the moxibustion group and (0.039 +/- 0.015) mm2 in the medication group] and NF-kappaB [(0.145 +/- 0.052)mm2 in the model group, (0.052 +/- 0.012) mm2 in the moxibustion group and (0.036 +/- 0.013) mm2 in the medication group], indicating the significant difference (P < 0.05, P < 0.001). There was no statistical difference between the moxibustion group and medication group (all P > 0.05).

CONCLUSIONThe warm moxibustion has great effect on regulation of blood lipids and anti-atherosclerosis, in which lowering expression of CD40-CD40L could be one of possible mechanisms to take effect of anti-atherosclerosis.

Objective To investigate the synergistic effect of etanidazole and paclitaxel on hepatocellular carcinoma H22 cells in mice. Methods To establish the murine xenografts, H22 cells was inoculated subcutaneously into the back of BALB/c mice. Among them, 40 tumor-bearing mice were divided into 4 groups by random number table method, 10 mice in each group, and each group injected with phosphate buffered saline (PBS), etanidazole (200 mg/kg), paclitaxel (1 mg/kg) and two drugs combination. Two hours after the administration, the mice were sacrificed by dislocation, and the drugs content in blood and tumor tissues of mice was measured by high-performance liquid chromatography. Sixty-five tumor-bearing mice were selected and divided into PBS non-irradiation group, PBS irradiation group, etanidazole irradiation group, paclitaxel irradiation group and two drugs combination irradiation group by random number table method, 13 mice/group. According to the grouping, the irradiated mice received 60Co source irradiation 2 hours after administration; the survival of 10 mice was observed at different time points, and the tumor volume was measured and calculated. The survival mice were killed by cervical dislocation 180 days after radiation. The other 3 mice in each group were killed after 2 days of irradiation, the tumor tissues were taken, and the expression of hypoxia inducible factor 1 (HIF-1) in these tumor tissues was detected by using immunohistochemistry. Statistical analysis of measurement data between groups was performed by using the one-way ANOVA and t test, and the survival analysis was made by Kaplan-Meier method. Results There was no significant difference of etanidazole and paclitaxel content in blood and tumor tissues between alone and combination administration groups at 2 hours after administration [etanidazole in blood: (55.5 ±4.7) μg/ml vs. (50.7±5.2) μg/ml; etanidazole in tumor: (31.2±3.5) μg/g vs. (33.6±5.4) μg/g; paclitaxel in blood: (316.9± 9.6)μg/ml vs. (289.5±10.3)μg/ml;paclitaxel in tumor: (161.7±7.2) μg/g vs. (181.3±11.6) μg/g; all P>0.05]. Within 40 days from the 10th day after the irradiation, the body weight of the irradiated group at each time point was significantly lower than that of the unirradiated group (all P< 0.05), but there was no significant difference in the body weight among the administration groups (all P>0.05). On the 40th day after irradiation, the tumor inhibition rates of the PBS irradiation group, etanidazole irradiation group, paclitaxel irradiation group, and two drugs combination irradiation group were 19.2％, 33.9％, 48.7％, and 61.6％, respectively. On the 180th day after irradiation, the survival rates of the PBS non-irradiation group, PBS irradiation group, etanidazole irradiation group, paclitaxel irradiation group, and two drugs combination irradiation group were 0, 0, 0, 12.5％, and 25.0％, respectively, and the median survival interval was 30.2, 54.7, 55.6, 83.4, and 102.8 d. After 2 days of irradiation, the positive expression rate of HIF-1 in the tumors tissues of PBS irradiation group, etanidazole irradiation group, paclitaxel irradiation group and two drugs combination irradiation group was lower than that in the PBS non-irradiation group, the differences were statistically significant [(45.7 ±4.8)％, (40.6 ±5.9)％, (24.5±5.6)％, (17.2±3.7％)％vs. (63.1±7.2)％, all P<0.05]. The positive expression rate of HIF-1 in the paclitaxel irradiation group and two drugs combination irradiation group was lower than that in the PBS irradiation group and etanidazole irradiation group (all P<0.05). Conclusion The combination of etanidazole and paclitaxel has synergistic radiation sensitization effect on hepatocellular carcinoma H22 cells in mice, and the expression level of HIF-1 is decreased, reflecting the decrease of hypoxic cells.

Objective To explore the mechanism about the expression of the hyperphosphorylated p38MAPK in the central nervous system (CNS) of experimental autoimmune encephalomyelitis (EAE) mouse and its relationship to the axonal damage, and investigate the potential regulation of SB203580 to the damaged axons in the CNS of EAE mouse.Methods SJL/J mice were used to establish the EAE model. Brain and spinal cord of EAE mice in the model group, SB203580 group and control group were used respectively at different time points. Stained with HE and Luxol Fast Blue (LFB), also the immunohistochemical detection was conducted with parallel phosphorylation of p38MAPK antibody staining and APP staining at the same time. By image analysis system, the number of positive signals, the coverage and the average density value in the cytoplasm of neuron in white matter lesions were measured.Results The model of EAE mice induced by PLP peptide manifested significant neurological symptoms, signs and features of relapse and remitting. Demyelinating change was observed in local regional white matter region. Compared with the model group, SB203580 group changed lighter, with its behavioral observations and had a significant weight gain (P<0.01). In addition to the control group, amyloid precursor protein (APP) expression was detected in other groups at various time points. Compared to the model group, APP expression was slighter than in SB203580 group. The number of positive cells and strength was significantly lower in the SB203580 group (P<0.01); expression of p38MAPK in EAE mice was observed at the earlier 7th day after immunization. Compared to the model group, expression of SB203580 group was lighter, positive number and intensity decreased markedly (P<0.01).Conclusion p38MAPK blockers SB203580 can not only inhibit activation of the p38MAPK in EAE mice, but also effectively reduce expression of APP which is symbolic target of EAE axonal injury, it is confirmed that the p38MAPK is indeed involved in the EAE axonal injury.
