OBJECTIVE: To determine whether chloroquine (CQ), an often used inhibitor of late autophagy and autophagosome/lyosome fusion, can inhibit proliferation of renal carcinoma cells and investigate its effect on sunitinib (ST)-induced apoptosis. METHODS: Renal carcinoma cell line 786 O and ACHN had been used as cellular model and 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (MTS) assay was carried out to detect the cell viability in response to CQ or ST treatment. Both transmission electron microscope and immunoblotting had been employed to observe apoptotic and autophagic process. To examine the involvement of autophagy in ST-dependent apoptosis, autophagy had been inhibited either chemically or genetically via utilizing autophagy inhibitor or specific small interference RNA (siRNA) targeted to either Ulk1 (unc-51-like kinase 1) or LC3 (microtubule associated protein 1 light chain 3 fusion protein), two essential autophagic proteins. RESULTS: Both ST and CQ induced cell viability loss, indicating that either of them could inhibit renal cancer cell proliferation. Clone formation experiments confirmed the aforementioned results. Furthermore, the combined ST with CQ synergistically promoted the loss of cell viability. By transmission electron microscopy and immunoblotting, we found that the ST induced both autophagy and caspase-dependent apoptosis. While 3-MA, an early autophagy inhibitor, reduced the ST-induced cleavage of poly (ADP-ribose) polymerase-1 (PARP-1), a substrate of caspase 3/7 and often used marker of caspase-dependent apoptosis, CQ promoted the ST-dependent PARP-1 cleavage, indicating that the early and late autophagy functioned differentially on the ST-activated apoptotic process. Moreover, the knock down of either Ulk1 or LC3 decreased the ST-caused apoptosis.Interestingly, we observed that rapamycin, a specific inhibitor of mTOR (mammalian target of rapamycin) and an inducer of autophagy, also showed to inhibit cell viability and increased the cleavage of PARP-1 in the ST-treated cells, suggesting that autophagy was likely to play a dual role in the regulation of the ST-induced apoptosis. CONCLUSION ST activates both apoptotic and autophagic process in renal carcinoma cells. Although autophagy precedes the ST-induced apoptosis, however, early and late autophagy functions differentially on the apoptotic process induced by this compound. Additionally, ST can coordinate with the inducer of autophagy to inhibit the cell proliferation. Further research in this direction will let us illuminate to utilize CQ as a potential drug in the treatment of renal carcinoma.

OBJECTIVETo evaluate the clinical efficacy and safety of Huayu Tongbi Recipe (HTR) combined methotrexate (MTX) in treating refractory rheumatoid arthritis (RRA).

METHODSTotally 167 RRA patients were assigned to the treatment group (73 cases) and the control group (94 cases) according to different therapeutic methods. Patients in the treatment group were treated with HTR combined MTX, while those in the control group were treated with leflunomide (LEF) combined MTX. Clinical signs and symptoms, RF, CRP, ESR, disease activity score 28 (DAS28), and safety indicators were compared between the two groups before treatment, at week 12 and 24 after treatment. The efficacy and safety indices were also evaluated.

RESULTSAt week 12 after treatment the total effective rate was 82.2% (60/73 cases) in the treatment group and 79.8% (75/94 cases) in the control group, showing no statistical difference between the two groups (chi2 = 0.15, P > 0.05). At week 24 after treatment the total effective rate was 78.1% (57/73 cases) in the treatment group and 755% (71/94 cases) in the control group, showing no statistical difference between the two groups (chi2 = 0.15, P > 0.05). There was statistical difference in the total effective rate between week 24 and week 12 in the control group (chi2 = 0.49, P < 0.05). Clinical signs and symptoms, RF, CRP, ESR, and DAS28 were significantly improved in the two groups after 12- and 24-week treatment (P < 0.01). There was no statistical difference in the improvement at week 12 after treatment between the two groups (P > 0.05). There was statistical difference in time of morning stiffness, tender joint numbers, swollen joint numbers, patient global assessment, RF, CRP, and DAS28 at week 24 after treatment between the two groups (P < 0.05). Besides, adverse reactions occurred less in the treatment group than in the control group (P < 0.01).

CONCLUSIONThe efficacy of HTR combined MTX was equivalent to that of LEF (10 mg per day) combined MTX, but with more stable therapeutic effects and less adverse reactions.

This study is to observe the effects of methopterin on the activation and bone resorption function of murine osteoclasts, which were obtained by induction from bone marrow cell and purified to the purity of 70%-80%. The mechanism underlying the inhibitory effects of methopterin on inflammatory bone destruction was explored. MTT method was used to determine the effect of methopterin on the proliferation of osteoclasts. Flow cytometric analysis was used to determine the effect of methopterin on the apoptosis of osteocalsts. TRAP stain, bone resorption lacuna stain and measurement of lacuna area were executed to determine the effects of methopterin on the activation and function of osteoclasts. ELISA method was used to determine the effect of methopterin on the MMP-9 secretion from osteoclasts. RT-PCR method was used to determine the effect of methopterin on the mRNA expression of RANK and MMP-9 in osteoclasts. The results showed that methopterin (0.1-10 micromol x L(-1)) inhibited the proliferation of osteoclasts, methopterin (0.1-10 micromol x L(-1)) could inhibit the activation and bone resorption function of osteoclasts and induced the apoptosis of osteoclasts. Methopterin (0.01-10 micromol x L(-1)) also decreased the mRNA expression of RANK, but only at 1-10 micromol x L(-1) decreased the mRNA expression of MMP-9. These results indicated that there were intense relation between the inhibitory effects on the activation and function of osteoclasts and the inhibition of inflammatory bone destruction by methopterin.

Rheumatoid arthritis (RA) is the most common inflammatory arthritis and a major cause of disability. Presently, the clinical therapeutic medicines for inflammatory and arthritic diseases are unsatisfactory due to severe adverse effects or ineffectiveness. The Guge Fengtong formula (GGFT), containing the standardized extracts of Dioscoreae Nipponicae Rhizoma, Spatholobi Caulis, and Zingiberis Rhizoma, has long been used for RA treatment by Chinese doctorsin China. However, the detailed anti-inflammatory and anti-arthritic activity of GGFT has not been reported so far. In the present work, we aimed to evaluate the anti-inflammatory and anti-arthritic effects of GGFT using three in vivo animal models, and tried to uncover its preliminarythe underlying mechanism of action mechanism in RAW 264.7 macrophages. The obtained results indicated that GGFT significantly attenuated ear edema, decreased carrageenan-induced paw edema, reduced the arthritis score, and reversed the weight loss of the complete Freund's adjuvant (CFA)CFA-injected rats. Additionally, marked decrease of in synovial inflammatory infiltration and synovial lining hyperplasia in the joints and decline of inflammatory factors (TNF-α and IL-1β) in the serum were observed in the GGFT-treated rats. In lipopolysaccharide-activated RAW264.7 macrophages, GGFT reduced the production of NO, PGE2, and IL-6, and inhibited the expression of iNOS, COX-2, and NF-κB expression. Our results demonstrated that GGFT possessed considerable anti-inflammatory activity and have had potential therapeutic effects on adjuvant induced arthritis in rats, which provided providing experimental evidences for its traditional application in the treatment of RA and other inflammatory diseases.

OBJECTIVETo observe effect of prescriptions replenishing vital essence, tonifying Qi and activating blood on expression of tumor necrosis factor-alpha (TNF-alpha) and interleukin-IP (IL-1beta) in serum and submaxillary gland of non-obese diabetic (NOD) mice with Sjogren's syndrome.

METHODThirty-two NOD mice were divided into four groups at random: the model group, the traditional Chinese medicine (TCM) group, the hydroxychloroquine group, the TCM and western medicine (WM) group, with 8 mice in each group. Eight Balb/C mice were taken as the normal normal control group. The TCM group was orally administered with 0.4 mL decoction replenishing vital essence, tonifying Qi and activating blood (100 g x kg(-1)) everyday; the hydroxychloroquine group were given 0.4 mL hydroxychloroquine (60 mg x kg(-1)) everyday; the TCM WM group were given 0.4 mL decoction, replenishing vital essence tonifying Qi and activating blood (50 g x kg(-1)) and hydroxychloroquine (60 mg x kg(-1)) everyday. Mice were sacrificed after eight weeks, and their arterial blood and tissues of submaxillary gland were collected. The levels of TNF-alpha, IL-1beta in serum were detected by ELISA. Expressions of TNF-alpha, IL-1beta protein in submaxillary gland were detected by immunohisto-chemistry.

RESULTCompared with other groups, TNF-alpha, IL-1beta in serum and submaxillary gland in the model group were higher (P < 0.05). The normal group showed lower serum TNF-alpha level than other groups (P < 0.05), but without statistical significance compared with the TCM group. IL-1beta in serum in the TCM group and the TCM WM group were lower than that of the hydroxychloroquine group (P < 0.05), but without statistical significance compared with the normal group. TNF-alpha protein expression in the TCM group and the TCM WM group showed no significant difference compared with the normal group, whereas the TCM WM group were notably lower than that of the hydroxychloroquine group (P < 0.05). IL-1beta expression in the TCM WM group showed no significant difference compared with the normal group.

CONCLUSIONThe decoction replenishing vital essence, tonifying Qi and activating blood can decrease the levels of TNF-alpha, IL-1beta in serum and submaxillary gland of NOD mice with Sjogren's syndrome. It may improve pathological damage of submaxillary gland by regulating Th1/Th2 cell factors, in order to achieve the therapeutic effect on SS.

Fibroblast-like synoviocytes (FLS) play a pivotal role in Rheumatoid arthritis (RA) pathogenesis through aggressive migration and invasion. Madecassoside (Madec), a triterpenoid saponin present in Centella asiatica herbs, has a potent anti-inflammatory effect. In the present study, Madec exerted an obvious therapeutic effect in reversing the histological lesions in adjuvant-induced arthritis (AIA) rats. To recognize the anti-rheumatoid potentials of Madec, we further investigated whether Madec interfered with FLS invasion and metalloproteinase (MMP) expression. In cultures of primary FLS isolated from the AIA rats, Madec (10 and 30 μmol·L) was proven to considerably inhibit migration and invasion of FLS induced by interleukin 1β (IL-1β), but exhibiting no obvious effect on cell proliferation. Madec repressed IL-1β-triggered FLS invasion by prohibiting the expression of MMP-13. Additionally, Madec suppressed MMP-13 transcription via inhibiting the MMP-13 promoter-binding activity of NF-κB. Our results further showed that Madec down-regulated the translocation and phosphorylation of NF-κB as demonstrated by Western blotting and immunofluorescence assays. In conclusion, our results suggest that Madec exerts anti-RA activity via inhibiting the NF-κB/MMP-13 pathway.
