Aim To establish a new paclitaxel resistant human mammary adenocarcinoma cell subline(MCF-7/Taxol) and investigate its characteristics.Methods A paclitaxel resistant human mammary adenocarcinoma cell subline(MCF-7/Taxol) was developed by gradually increasing the concentration of Taxol from the parent cell line MCF-7 in vitro.The multidrug resistance of MCF-7/Taxol to anticancer agents was evaluated by SRB assay;the distribution of their cell cycles was detected by flow cytometry;the positive expression rate of P-gP、LRP、ToPoII、GST?、ER and PR was measured by S-P immunohistochemistry;the intracellular accumulation of Taxol was assessed by HPLC;the morphological features and the celluar ultrastructure characteristics were observed respectively by light microscopy and scanning electron microscopy.Results MCF-7/Taxol was resistant to several chemotherapy agents,such as Hydroxycamptothecine,Epirubicin,Doxorubicin,Mitoxantone and so on.The IC50 of MCF-7/Taxol to Taxol was 525 times higher than that of MCF-7,and the IC50 of MCF-7/Taxol stopped administrating Taxol for three months was 150 times higher than that of MCF-7.The multiplication time of MCF-7/Taxol was longer than that of the natural cell and the proportion of cells in S-phase increased while that in G1-phase decreased.The expression levels of P-gp、LRP and GST? increased,and ER and PR were not observed.The morphology of MCF-7/Taxol became larger and irregular,and the surface of natural cell was in the shape of floss,but MCF-7/Taxol was in the shape of bead.The intracellular of Taxol was observed in both MCF-7/Taxol and stoppage administrating.Conclusions MCF-7/Taxol cell subline was a typical multidrug resistant cell line which had basic characteristics of drug resistance cells.It was supposed that there was a cell subline which was tumor stem cell of MCF-7 included in this multidrug resistant cell line.

Objective To evaluate the value of 18F-FDG PET/CT in early in vivo monitoring of tumor response to cisplatin,and analyze the relationship between 18F-FDG uptake in tumor and the corresponding pathological changes.Methods Thirty VX2 rabbits were divided into 5 groups by random number table with 6 in each group,including 4 treatment groups and 1 control group.18F-FDG PET/CT were performed before and after (6,12,24 and 36 h post-injection respectively) intravenous administration of cisplatin (7 mg/kg) in the treatment groups,respectively.The control group was injected with physiological saline followed by 18F-FDG PET/CT.The ROI was drawn and the SUVmax and T/NT ratio were calculated.The tumor necrosis rate and apoptosis index were observed by histopathologic examination.Paired t test,GamesHowell test and arcuation correlation analysis were used to analyze the data.Results Significant differences were found in SUVmax and T/NT of the control group before and after injection of physiological saline (6.58±1.67 vs 9.77±2.45,52.93±3.90 vs 29.34±3.31;t=-5.480,17.593,both P＜0.05).18F-FDG uptake decreased after 6 h post-injection of cisplatin,with the mean SUVmax decrease rate of (11.83±8.89) ％ and the mean T/NT decrease rate of (59.00±8.22)％.In the 24 h treatment group,18F-FDG uptake decreased most,and the mean SUVmax decrease rate was (42.33±33.80)％,the mean T/NT decrease rate was (83.50± 7.69) ％.The SUVmax and T/NT of those 2 groups were significantly different from those of the control group,and no difference was found between the 2 treatment groups(all P＜0.05).The changes of SUVmax and T/NT were positively correlated with apoptosis index and tumor necrosis rate (r=0.750,0.794,0.804,0.874,all P＜0.05).Conclusion 18F-FDG PET/CT is a sensitive method for monitoring early response to tumor chemotherapy in VX2 tumor-bearing rabbits at 24 h after treatment.

This study is purposed to investigate the effects of praeruptorin A (PA) and praeruptorin C (PC) on UGT1A1 in HepG2 cells through hCAR pathway. PA and PC were incubated with HepG2 cells for 24 h and 48 h, mRNA and protein expressions of UGT1A1 were determined by real-time PCR and Western blotting assays. Additionally, effects of PA and PC on UGT1A1 mRNA and protein expressions were also measured after transient transfection of a specific CAR siRNA for 72 h in HepG2 cells. UGT1A1 mRNA and protein expression levels were significantly increased by PA and PC after incubation for 48 h. Moreover, the mRNA and protein up-regulations of UGT1A1 were attenuated by transient transfection of a specific CAR siRNA, suggesting the induction was mediated by CAR. The results suggest that PA and PC can significantly up-regulate UGT1A1 expression partially via the CAR-mediated pathway.

Objective:The relationship between the effect of early metabolism in 18F-FDG PET/CT and conventional CT based on the RE-CIST standard to evaluate the best objective response after chemotherapy in patients with non-small cell lung cancer (NSCLC). Meth-ods:We studied 40 patients with unresectable locally advanced or advanced NSCLC that were confirmed pathologically. The patients were 35 years old to 78 years old and included 31 males and 9 females. Three patients have unresectable stageⅢA, 8 patients have stageⅢB, 29 patients have stageⅣ, 12 patients have squamous cell carcinoma, and 28 patients have adenocarcinoma. The PET/CT for the effect of chemotherapy was evaluated in NSCLC according to the SUV standard (SUVmax reduction>30%of primary lung can-cer after one cycle of chemotherapy), and the CT for the effect of chemotherapy was evaluated on the basis of NSCLC according to the RECIST standard. The objectives of the study are as follows:compare the differences and consistency between 18F-FDG PET/CT metabol-ic response after the first cycle of chemotherapy and the RECIST best objective response after the first or second cycle of chemothera-py with the paired chi-square test and kappa test;calculate the 18F-FDG PET/CT to predict the best objective response of two cycles of chemotherapy according to RECIST on the basis of NSCLC in terms of sensitivity, specificity, accuracy, positive predictive value, and neg-ative predictive value;compare the differences in SUVmax reduction between the metabolic remission group and metabolic no relief group with the two-sample t-test. All statistical methods were 0.05 for the inspection level, and P<0.05 was considered statistically sig-nificant difference (SPSS19.0). Results:Differences were found between the first cycle of chemotherapy for the RECIST best objective response and 18F-FDG PET/CT metabolic response (χ2=5.063, P=0.021), and the results had bad consistency (Kappa=0.240, P=0.085). No differences were observed between the second cycle of chemotherapy for the RECIST best objective response and 18F-FDG PET/CT metabolic response (χ2=2.083, P=0.146);the results had good consistency (Kappa=0.413, P=0.006). The sensitivity, specificity, accura-cy, positive predictive value, and negative predictive value were 82%, 61%, 70%, 61%, and 82%, respectively. The differences in SUV-max reduction between the metabolic remission group and metabolic no relief group with the two-sample t-test were statistically sig-nificant (P<0.001). Conclusion: 18F-FDG PET/CT may predict the best objective response to chemotherapy for NSCLC patients. Com-pared with conventional CT, 18F-FDG PET/CT can be an early and accurate way to evaluate the chemotherapy effect in NSCLC.
