Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for dysmenorrhea due to deficiency cold. Methods: A total of 70 patients with dysmenorrhea who met the inclusion criteria were randomized into a mild moxibustion group and a herbal cake-partitioned moxibustion group by the random number table, with 35 cases in each group. Shenque (CV 8), Zhongji (CV 3) and bilateral Zigong (EX-CA 1) were selected for both groups. The treatment continued for 3 menstrual cycles. The visual analog scale (VAS) and COX menstrual symptom scale (CMSS) were scored in both groups before treatment, after treatment and at the end of the 3rd menstrual cycle after treatment. The clinical efficacy was evaluated at the end of the 3rd menstrual cycle after treatment. Results: After treatment, the clinical efficacy of the herbal cake-partitioned moxibustion group had the tendency to be superior to that of the mild moxibustion group, while there was no statistically significant difference in the overall efficacy between the two groups (P>0.05). The VAS and CMSS scores after treatment and at the follow-up were significantly lower than those before treatment in both groups (all P<0.05). At the follow-up, the VAS scores in both groups had no significant intra-group differences from those after treatment (both P>0.05). The CMSS scores in both groups were significantly lower than those after treatment (both P<0.05). The VAS scores at the follow-up of both groups had no statistical differences from those after treatment (both P>0.05). After treatment, the CMSS score in the herbal cake-partitioned moxibustion group was significantly lower than that in the mild moxibustion group (P<0.05). At the follow-up, there were no statistical differences in the CMSS score between the two groups (P>0.05). Conclusion: The herbal cake-partitioned moxibustion has the same therapeutic efficacy for dysmenorrhea as the mild moxibustion; the two moxibustion methods can significantly improve the concomitant symptoms of dysmenorrhea, and the herbal cake-partitioned moxibustion is little better.

To investigate the rat intestinal absorption of stearic acid-octaarginine (SA-R8) modified solid lipid nanoparticles containing paclitaxel (SA-R8-PTX-SLN), compared with the commercially available preparation of PTX (Taxol) and PTX-loaded solid lipid nanoparticles (PTX-SLN), the in situ intestinal absorption of SA-R8-PTX-SLN was investigated by means of single-pass rat intestinal perfusion technique. The absorptions of the preparations were investigated at different intestinal segments, different drug concentrations and in the presence of P-glycoprotein inhibitor (verapamil). The results showed that PTX could be absorbed at each intestinal segment and the three preparations all showed maximum absorptions at the duodenum. The cumulative absorptions of three preparations at each intestinal segment appeared SA-R8-PTX-SLN > PTX-SLN > Taxol (P < 0.05). SA-R8-PTX-SLN showed a liner absorption manner at the duodenum in the examined drug concentration range. The cumulative absorptions of Taxol and PTX-SLN were significantly promoted after the addition of P-glycoprotein inhibitor (verapamil) into the preparation (P < 0.05), but absorption of SA-R8-PTX-SLN existed no significantly difference compared with the preparation without verapamil (P > 0.05). SA-R8 and SLN might both effectively improve the oral absorption of PTX in the intestinal tract.

OBJECTIVETo study the antiproliferation effect on HepG2 cells and its underlying mechanism of the active chemical composition of the Viburnum Odoratissimum.
METHODS3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) reduction assay and trypan blue dye exclusion assay were used to assess the effect of vibsane-type diterpenoids on the proliferation of various tumor cells. Alterations in cell cycle and apoptosis were determined by flowcytometry. The enzymatic activity of caspase-3/7 was measured by Apo-ONE homogeneous Caspase-3/7 Assay kit.
RESULTSCompound 1 #, a vibsane-type diterpenoid, was found to significantly inhibit the growth of HepG2 cells by anticancer proliferation activity screening. It was demonstrated that the modified groups on side chain coupled to C11 site affected the cell growth-inhibition activity of compounds by structure-activity analysis. In addition, HepG2 cell line was most sensitive to compound 1 #, which induced growth arrest of HepG2 cells in a dose- and time-dependent manner. Study on the mechanisms underlying these effects indicated that compound 1 # induced significant G0/G1 phase arrest of HepG2 cells in a time- and concentration-dependent manner. Meanwhile, It was found that higher concentrations of compound (5-10 micromol/L) caused evident increase in the unmber of apoptotic cells and dose-dependent activation of caspase-3/7.
CONCLUSIONVibsane-type diterpenoids could significantly inhibit the growth of HCC HepG2 cells. Induction of cell cycle arrest and apoptosis may play important roles in their anticancer effects.

This study was aimed to investigate the reversing effect of arsenic trioxide (As2O3) on methylation status and the regulatory effect on transcription of malignant lymphoma cell line CA46 p16 gene as well as their possibe mechanisms. The hypermethylated malignant lymphoma cell line CA46 was used as a subject of experiment for studying relation of gene methylation with expression. The effect of As2O3 on the proliferation and viability of CA46 was detected by SRB method, the change of p16 methylation status after exposure to As2O3 was determined by nMSP, the expressions of p16, DNMT1, DNMT3A, DNMT3B mRNA were assayed by RT-PCR, the influence of As2O3 on CA46 cell cycle was analyzed by flow cytometry using analytical method for DNA ploidy. The results showed that the methylation level of p16 gene was obviously reduced after treatment with As2O3 for 72 hours and the hypermethylation of p16 gene was successfully reversed; the expression of p16 gene in untreated (control) group was low while it was enhanced in treated groups; the gray scale ratios of p16 gene to beta-actin in groups treated with As2O3 of concentration 0.5, 1.0 and 2.0 micromol/L were 0.33+/-0.10, 0.57+/-0.11 and 0.67+/-0.09 respectively, exhibiting a significant difference in comparison with 0.73+/-0.13 of positive control (p<0.01); as compared with the untreated group, the expression of DNMT3A and DNMT3B in treated groups was obviously down-regulated in a concentration-dependent manner, while expression of DNMT1 was nearly unchanged; as compared with control, all the 3 different concentrations of As2O3 could inhibit the proliferation of CA46 cells and increase the cell number in G0/G1 phase. It is concluded that the As2O3 may up-regulate the expression of p16 gene, recover the activity of p16 gene, thereby promote the regulatory function on cell cycle resul-ting in arrest of cells in G0/G1 phase and inhibit growth of tumor cells through depressing the expression of DNMT3A and DNMT3B and/or directly reversing the methylation status of p16 gene.
