The role of pulchinenoside (PULC) in the regulation of MeCP2 expression was investigated in RA model rats. Adjuvant arthritis rats were used as RA model rats, and fibroblast-like synoviocytes (FLS) from the RA model rats were cultured. The effect of 100 mg x kg(-1) PULC gavage treatment on the MeCP2 expression and the effect of MeCP2 siRNA on the expression of SFRP2 and β-catenin were detected by real time qPCR and Western blotting. The role of PULC in the FLS proliferation was detected by MTT. The results showed that the MeCP2 expression was down-regulated, the SFRP2 expression was up-regulated and the FLS proliferation was inhibited in FLS after therapy. MeCP2 siRNA significantly inhibited the MeCP2 expression, up-regulated the SFRP2 expression and inhibited the β-catenin expression in FLS from RA model rats. PULC may increase the SFRP2 expression, inhibit the Wnt signaling and inhibit the FLS proliferation in FLS from the RA model rats by inhibiting the MeCP2 expression.

OBJECTIVETo probe in the possible acting mechanism of Bizhongxiao Decoction (BZXD) for treatment of early active rheumatoid arthritis (RA) by way of observing the two-dimensional gel electrophoresis map of proteins in peripheral blood mononuclear cells (PBMCs) of healthy persons and RA patients (intervened or un-intervened with BZXD), analyzing the differential proteins and seeking out the RA associated proteins.

METHODSEighteen patients with early active RA were randomized into the BZXD group and the methotrexate (MTX) group, nine in each group, they were treated with BZXD (contained 15 Chinese herbs, as Herba Hedyotis diffusae, Herba Sarcandrae glabrae, Radix Salviae miltiorrhizae, Caulis Trachelosperi, Rhizoma Drynariae, Semen Coicis, etc.) and MTX combined with nimesulide Tablets respectively, three months as a treatment course, and their blood samples were collected for observation. Besides, blood samples from 9 healthy persons were taken as normal controls. PBMCs were isolated from blood using lymphozytes separation medium, and total protein in the cells was extracted through immobilized pH gradient two-dimensional gel electrophoresis. After Coomassie brilliant blue G250 staining, gel-image analysis was performed using PDQuest software. The differentially expressed proteins were identified by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS). Then partial proteins were validated by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSThe 2-DE protein profile of PBMCs from healthy persons and RA patients before and 3 months after treatment were obtained, and 23 differential protein spots were found, 14 from 18 differential protein spots were successfully identified, of which 8 proteins were up-regulated and 6 proteins were down-regulated in RA patients as compared with control. After 3-month treatment, 5 differentially expressed proteins showed more obvious in the BZXD group than in the MTX group. RT-PCR verified that the expression of ApoA-I in all the three groups was consistent with the outcomes of 2-DE.

CONCLUSIONSSome differentially expressed proteins exist in the PBMCs of RA patients, which may play a potential role in the pathogenesis of RA; BZXD may treat RA by way of regulating the expression of some differential proteins in patients.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.

OBJECTIVETo observe and compare the quality of life (QOL) and survival time in patients with advanced primary hepatic cancer (PHC) after they have been treated by the combination of ganji recipe and interventional therapy with Fructus Bruceae Oil Emulsion (FBE) or by the trans-hepatic arterial chemical embolization (TACE) adopting Seldinger's technique.

METHODSSeventy-seven patients with advanced PHC were randomly assigned to two groups, 37 patients in the control group treated with TACE alone, and 40 in the treatment group with the combined therapy. One therapeutic course was 4 weeks, and the intervention therapy was repeated generally after an interval of 4-6 weeks according to patients'condition ,the average intervention frequency was 2.3 for one case. The QOL and the survival time in patients were evaluated after treatment.

RESULTSSignificant difference was shown in the changes of the Karnofsky score between the two groups (P < 0.05). The scores suggested that the improvements in the treatment group, including patients'physical energy enhancing, symptoms alleviating and overall QOL improving, were superior to those in the control group (P < 0.05). No significant difference of the 3-month survival rate between the two groups was found (P > 0.05), but the 0.5- and 1-year survival rate were significantly superior in the treatment group to those in the control group (67.6% vs. 42.4% and 38.2% vs. 16.1%, respectively). The median survival time in the two groups was 8.9 and 5.3 months respectively.

CONCLUSIONCombination of ganji recipe and interventional therapy with FBE in treating PHC could improve patients' QOL, raise the 0.5- and 1-year survival rate, and prolong the survival time, suggesting TCM treatment has an affirmative significance for enhancing the therapeutic efficacy and improving the prognosis in patients.
