Fever model was made by intravenously injected leucocytic pyrogen(LP,EP). Chai Ge Jie Ji Tang CGJJT fluid was perfused into rabbits stomach by mouth. 65 New Zealand white rabbits were divided into four groups: (1) control group; (2) LP group; (3) CGJJT fluid group; (4) LP+ CGJJT fluid group. Effects of CGJJT fluid on LP fever and cAMP concentration in cerebrospinal fluid (CSF)were observed. The results obtained from our experiments showed that: (1) The rectal temperature of normal rabbits markedly affected by CGJJT fluid. (2) Febrile response of LP was significantly inhibited by CGJJT fluid (P

0.05). (2) Febrileresponse of LP was significantly inhibited by No.Ⅰ, No.Ⅱ, respectively. Concentrationof cAMP in CSF of LP group, 1 hour after injection of LP, was 140.94?51.74 pmol/ml, while that of the No.Ⅰ+ EP group was (83.48?8.11 pmol/ml) obviously lowerthan that of LP group (P

The dissolution rates of the cephalexin tablets made by five t actories in China were determined with rotating basket method. The dissolution constants Ki were calculated using single exponential method. The analysis of variance was carried out for Ki. The results showed that constants Ki of products from different factories were significantly different (p

Primary hepatic carcinoma (PHC) is one of the most common cancers worldwide and is the leading cause of death in China. Multidisciplinary treatment is widely accepted as the way to improve the prognosis of PHC, and non-surgical therapy now plays a more and more important role. The purpose of this article is to review the current status and progress of non-surgical treatments of PHC, such as TACE, local ablation, radiotherapy and systemic therapy.

Objective:To explore the effect of costunolide on sensitivity of chronic myeloid leukemia cell line K562/ADR to doxorubicin and its mechanism.Methods:K562/ADR cells in the logarithmic phase were used, and the cells were treated with different concentrations of costunolide, doxorubicin or costunolide combined with doxorubicin for 72 h. The cell proliferation was detected by CCK-8 method, the cell proliferation rate was calculated, and the half inhibitory concentration (IC 50) of the two drugs was obtained. The cells were treated with 10 μmol/L costunolide, 10 μmol/L doxorubicin or costunolide combined with doxorubicin for 48 h, the apoptotic rate was detected by flow cytometry, and the expression level of p38-MAPK pathway related proteins was detected by Western blot. Results:The cell proliferation rate in the costunolide combined with doxorubicin group was lower than that in the corresponding concentration of the two drugs alone groups, and the differences were statistically significant both ( P < 0.05). The IC 50 of doxorubicin for K562/ADR cells was (13.50±0.86) μmol/L, and costunolide was (7.30±0.55) μmol/L ( t = 7.044, P = 0.002). The results of flow cytometry showed that the apoptosis rate of K562/ADR cells in the 10 μmol/L costunolide combined with 10 μmol/L doxorubicin group was higher than that of the blank control group, costunolide alone group and doxorubicin alone group, and the differences were statistically significant [(19.68±3.21)% vs. (2.96±0.87)%, (9.34±2.89)%, (9.18±2.13)%, all P<0.01]. Compared with the 10 μmol/L costunolide alone group and the 10 μmol/L doxorubicin alone group, the expression of the apoptosis inhibitor protein bcl-2 in the two-drug combination group was down-regulated, and the expressions of bad, p-p38, cleaved-caspase-3 and cleaved-PARP proteins were up-regulated. Conclusion:Costunolide can enhance the inhibitory effect of doxorubicin on the proliferation of K562/ADR cells and promote doxorubicin-induced apoptosis, which may reverse the drug resistance of K562/ADR cells by regulating the p38-MAPK pathway.

Objective To explore the effects of isoalantolactone on the proliferation of human chronic myelogenous leukemia drug-resistant cell line K562/A02. Methods K562/A02 cells were treated with 6.25, 12.5, 25, 50 and 100 μmol/L isoalantolactone for 24 and 48 h, cell viability was analyzed with MMT assay. K562/A02 cells were treated with 10, 15, 20 μmol/L isoalantolactone for 24 h. Flow cytometry was used to examine the effect of isoalantolactone on the cell-cycle and apoptosis of K562/A02 cells. The related proteins were analyzed using Western blot. One-way ANOVA was used for statistical analysis. Results Isoalantolactone effectively inhibited the proliferation of K562/A02 cells in a dose-dependent manner (P<0.05) with IC50 value of (15.00 ±1.03) μmol/L at 24 h, respectively; Flow cytometry displayed that isoalantolactone may induce K562/A02 cells apoptosis in a concentration-dependent manner (P<0.05). The apoptotic rate significantly increased from (2.71 ±0.52) % in the control group to (19.10 ±1.55) %, (27.61 ± 2.32)%and (32.01±3.01)%(F=33.901, P<0.05), respectively, after treatment with 10, 15, and 20 μmol/L of isoalantolactone for 24 h. The percentage of cells in the S phase increased from (57.80±2.11) % to (68.62± 2.89)%, (78.41±3.51)%and (80.61±2.90)%, respectively (F=51.328, P<0.05). Western blot indicated that the expression of bcl-2, p-bcr-abl, p-STAT5, CDK2 and cyclin A significantly decreased (P< 0.05), and that of cytochrome C, Bax, and p21 increased with the increasing of isoalantolactone concentration (P< 0.05). Conclusion Isoalantolactone can significantly inhibit the proliferation of K562/A02 cells through bcr-abl-STAT5 signaling pathway.
