Effect of the Haoqinqingdan decoction on damp-heat syndrome in rats with influenza viral pneumonia

Objective: To investigate the effect of Chinese medicine prescription-Haoqinqingdan decoction on damp-heat syndrome in rats with influenza viral pneumonia and its influence on the immune function. Methods: A total of 48 Wistar rats were randomly divided into the normal control group, the damp-heat syndrome model group, the Haoqinqingdan decoction group (high, medium and low dose group) and the ribavirin group. The body temperature and weight of rats in each group were recorded after modeling. After treatment for 6 d, the concentration of T lymphocyte subgroup (CD3+ CD4+ , CD3+ CD8+ ) was determined by flow cytometry. The OD value of IFN毭/IL-4 was detected by double-antibody sandwich ELISA method, and its concentration was acquired through conversion. Results: After modeling, the temperature and weight of rats in each modeling group showed the increasing trend ( P<0.01). From the second day of treatment, there was significant difference in the body mass between groups, and the rat weight of the control group was higher than in the modeling group ( P<0.05 or 0.01). With the advances of treatment, only the temperature in the medium and high dose Haoqinqingdan decoction groups declined significantly ( P<0.05). After treatment, the CD4+ /CD8+ ratio of the damp-heat syndrome model group decreased more significantly compared with the control group. Elevated CD3+ CD8+ percentages and declined CD4+ /CD8+ ratios can be observed in the low dose group and ribavirin group ( P<0.05). Moreover, the CD3+ CD4+ percentage of ribavirin group was lower than in the control group ( P<0.05). After treatment, the IFN-毭 and IFN-毭/ IL-4 levels in the peripheral blood of rats in the dampheat syndrome group were obviously higher than in the control group ( P<0.05). Conclusions: Compared with ribavirin, the high dose Haoqinqingdan decoction can improve the ratio of T lymphocyte subgroup and Th1/Th2 cell balance more effectively.

Effect of Sanhuangyilong decoction plus methotrexate on tumor necrosis factor alpha and interferon gamma in serum and synovial fluid in rheumatoid arthritis patients with symptom pattern of damp heat obstruction

OBJECTIVE: To investigate the effect of Sanhuangyilong decoction plus methotrexate(MTX) on Interferon gamma(IFN-γ) and tumor necrosis factor alpha(TNF-α) in the serum and synovial fluid of rheumatoid arthritis(RA) patients with damp-heat-obstruction symptom pattern, Sanhuangyilong decoction and the role of TNF-α and IFN-γ in the development of RA.METHODS: RA inpatients with damp-heat-obstruction symptom pattern(partly with knee joint effusion) were selected as the research subjects. Before the treatment, healthy subjects and osteoarthritis(OA) patients with knee joint effusion were assigned to the serum control group and the synovial fluid control group, respectively; during the treatment, RA patients with damp-heat-obstruction symptom pattern were divided into two groups:one is combined group that was administered Sanhuangyilong decoction plus MTX; the other group was MTX group that received MTX only. The expression levels of TNF-α and IFN-γ in the serum and synovial fluid were measured with enzyme-linked immunosorbent assay(ELISA) before and after the treatment, and the peripheral blood levels of erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) and disease activity score in 28 joints(DAS28)were determined.RESULTS: Before treatment, the serum levels of TNF-α and IFN-γ in the RA patients with dampheat-obstruction symptom pattern were higher than those in healthy control group(P < 0.05).The expression levels of TNF-α and IFN-γ in the synovial fluid of the RA patients were higher than those in the serum of the RA patients(P < 0.05). The expression levels of TNF-α and IFN-γ in the synovial fluid of the RA patients were higher than those of the sy-novial fluid of the osteoarthritis patients(P < 0.05).The expression of TNF-α and IFN-γ in the serum and synovial fluid of the RA patients had no correlation with the inflammatory activity index ESR, CRP,or DAS28(P > 0.05). After 2 weeks of treatment, the expression level of TNF-α and IFN-γ in the combined group had increased, although the difference was not statistically significant(P > 0.05); in contrast, ESR, CRP, and DAS28 decreased, and the difference was statistically significant(P < 0.01). After 4 weeks of therapy, TNF-alpha and IFN-γ, ESR,CRP, and DAS28 in the combined group decreased compared with the before-treatment levels(P <0.01). After 2 w of treatment, the differences in the TNF-α and IFN-γ expression levels in the combined group were not statistically significant(P > 0.05)compared with that in the MTX group, although there were statistically significant differences in the ESR, CRP, and DAS28(P < 0.05). After 4 weeks of treatment, differences in TNF-α, IFN-γ, ESR, CRP, and DAS28 in the combined group compared with MTX group were statistically significant(P < 0.01).CONCLUSION: TNF-α and IFN-γ might be involved in the development of RA. The RA patients with damp-heat-obstruction symptom pattern show better benefits from the treatment of Sanhuangyilong decoction plus MTX, and the treatment is superior to that of using MTX only.

Influence of isochronal heat treatment on damping behavior of AZ61 alloy

Strain amplitude dependence of the logarithmic decrement was measured and studied on an AZ61 magnesium alloy at room temperature. Measurements were carried out before and after isochronal thermal treatment step by step with increasing temperature. For all specimens, the strain dependence of the logarithmic decrement exhibits two regions. At lower strains the logarithmic decrement is strain independent and in the higher strain region it depends strongly on strain amplitude. The strain-independent logarithmic decrement is mainly composed of thermoelastic damping and dislocation damping, which can be explained by Granato-Lücke theory. In addition, the strain-independent logarithmic decrement for the specimens annealed at higher temperatures is a little lower than that for as-cast specimen, and it increases with increasing temperature of heat treatment. Microstructure changes due to heat treatment are responsible for changes of the logarithmic decrement.

Effect of different heat treatment process on damping peak of 6061Al/SiC_p MMC produced by spray codeposition

Effects of five typical heat treatment processes on the damping properties and the damping peak of 6061Al/SiC p MMC fabricated by spray codeposition were studied. The results show that the internal friction spectra of various heat treated samples exhibit the damping peak versus temperature between 130 ℃ and 200 ℃. Furthermore, the peak temperature as well as the peak height increases with increasing frequencies. By Arrhenius equation the active energy of the damping peak can be gotten, which is above 1 eV. On the other hand, different quenching treatments affect the damping peak remarkably, when the rate of cooling is above that of water quenching, the damping peak will shift to higher temperature as cooling speed is enhanced.
