Effect of row-like puncture at sternocleidomastoid on peripheral facial palsy at recovery stage / 中国针灸

OBJECTIVE@#To observe the effect of conventional acupuncture combined with row-like puncture at sternocleidomastoid on peripheral facial palsy at recovery stage.@*METHODS@#A total of 60 patients with peripheral facial palsy at recovery stage were randomized into an observation group and a control group, 30 cases in each one. Acupuncture was applied at affected Cuanzhu (BL 2), Yangbai (GB 14), Sibai (ST 2), Quanliao (SI 18), Jiache (ST 6), Dicang (ST 4), Hegu (LI 4), Taichong (LR 3) and Zusanli (ST 36) in the control group. On the basis of the treatment in the control group, row-like puncture was applied at sternocleidomastoid (1 needle was punctured at muscle origin and insertion respectively, 3 to 4 needles were row-like punctured at the connection line of muscle origin and insertion). The treatment was given once a day, 5 times were as one course, with 2-day interval, totally 4 courses were required in the both groups. The house-brackmann (H-B) facial nerve function grade, facial nerve function rating system-dynamic view rating scale score and facial disability index (FDI) scale score [including scores of FDI physical function (FDIp) and FDI social life function (FDIs)] before and after treatment were observed, and the clinical efficacy was evaluated in the two groups.@*RESULTS@#After treatment, the H-B facial nerve function grades were improved compared before treatment in the both groups (@*CONCLUSION@#Compared with conventional acupuncture, combination therapy with row-like puncture at sternocleidomastoid can improve the therapeutic effect of peripheral facial palsy at recovery stage.

Enhancing effect of chidamide on the sensibility of human chronic myeloid leukemia K562/ADM cells to daunorubicin / 解剖学报

Objective: To investigate whether chidamide (CDM) could influence the sensibility of human chronic myeloid leukemia K562/ADM cells to daunorubicin (DNR) and its possible mechanism. Methods: The K562 and K562/ADM cells were cultured in vitro and treated with CDM and(or) DNR for 48 hous, and then the cell viability was measured by cell counting kit-8(CCK-8) assay. The proliferation, cell cycle and apoptosis were analyzed by flow cytometry. Western blotting was performed to measure the protein levels of histon 2AX (H2AX), γH2AX (Serl39), ataxia telangiectasia mutated gene (ATM), p-ATM (Serl981), breast cancer susceptibility protein 1(BRCAl), and p-BRCAl (Serl524). Results: DNR remarkably inhibited the cell activity of K562/ADM cells in dose-dependent manner with a half maximal inhibitory concentration(IC50) value of 11.76 μmol/L, and the resistant factor was 18.09. Co-treatment with CMD and DNR produced a synergistic effect confidence interval(GI) (CI<1) with a reversal fold of 8.11. DNR remarkably inhibited proliferation (P<0.05), induced G2/M phase arrest and apoptosis (P<0.05), these effects were enhanced under non-toxic concentration of CMD (P<0.05). K562/ADM cells had a significantly higher protein levels of ATM and BRCA1 than K562 cells (P<0.05). DNR significantly up-regulated the protein levels of γH2AX, p-ATM and p-BRCAl (P<0.05), and the protein level of γH2AX appeared higher in the combination group compared to DNR alone (P<0.05); however, the co-treatment with CMD and DNR induced a decreased expression of p-ATM and p-BRCAl than the DNR alone (P< 0.05). Conclusion: CDM may enhance the sensibility of K562/ADM cells to DNR by up-regulating the protein level of γH2AX, and down-regulating the protein levels of p-ATM and p-BRCAl.

Wogonoside reverses cisplatin resistance in SGC7901/cDDP cells through inhibition of PI3K/Akt/Nrf2/ARE signaling pathway / 生理学报

The aim of this study was to investigate the effect of wogonoside (WGS) on the cisplatin (cDDP) resistance in human gastric carcinoma SGC7901/cDDP cells and its possible mechanism. The drug-resistant SGC7901/cDDP cells were established by stepwise exposure to cDDP. CCK-8 assay was employed to detect the cytotoxic effect of WGS and cDDP on SGC7901/cDDP cells, and the combined effect of WGS and cDDP was analyzed by Chou-Talalay method. Flow cytometry was used to determine the apoptosis and reactive oxygen species (ROS). Nuclear factor erythroid-2 related factor 2 (Nrf2) gene was knocked down by using the short hairpin RNA (shRNA) approach. The protein levels of Nrf2, NAD(P)H:quinone oxidoreductase 1 (NQO1), glutathione S transferase-π (GST-π), multidrug resistance-associated protein 1 (MRP1), cleaved Capase-3, p-Akt and Akt were detected by Western blotting. The result showed that after various concentrations of WGS and/or cDDP treatment for 48 h, the cell viability was remarkably reduced in a dose-dependent manner (P < 0.05). When the inhibition rate exceeded 16%, the combination of WGS and cDDP produced a synergistic effect. The protein levels of p-Akt, Nrf2 and MRP1 in SGC7901/cDDP cells were higher than those in SGC7901 cells (P < 0.05). WGS and LY294002 (PI3K inhibitor) both remarkably decreased the phosphorylation level of Akt (P < 0.05), down-regulated the protein level of Nrf2 (P < 0.05), increased the content of ROS (P < 0.05), up-regulated the protein level of cleaved Caspase-3 (P < 0.05), and induced apoptosis (P < 0.05). Meanwhile, N-acetyl-L-cysteine (NAC) decreased apoptosis and oxidative stress reaction induced by WGS (P < 0.05). WGS and Nrf2 gene silencing both down-regulated the protein levels of NQO1, GST-π and MRP1 (P < 0.05). These results suggest that WGS may reverse cDDP resistance in SGC7901/cDDP cells through blocking the PI3K/Akt/Nrf2/ARE signaling pathway, thus enhancing the cytotoxicity of cDDP and inducing oxidative stress reaction and apoptosis.

Astragaloside IV prevents lipopolysaccharide-induced injury in H9C2 cardiomyocytes / 中国天然药物

This study aimed to investigate the protective effects of astragaloside IV (AS IV) on lipopolysaccharide (LPS)-induced injury in H9C2 cardiomyocytes. H9C2 Cardiomyocytes were cultured with LPS (10 μg·mL(-1)) for 4 h and treated with AS IV at 50, 100, and 150 μmol·L(-1) for various durations. Cell viability was determined by MTT. The content of released TNF-α and IL-6 from cardiomyocytes were evaluated by enzyme-linked immunosorbent assay (ELISA). The levels of superoxidase dismutase (SOD), malondialdehyde (MDA), lactate dehydrogenase (LDH), and creatine phosphate kinase (CK) were measured by using commercial available kits. The mRNA and protein expression levels of NF-κB p65 were measured by RT-PCR and Western blotting, respectively. And the NF-κB p65 activity was measured by ELISA. Our results demonstrated that AS IV at 50, 100, and 150 μmol·L(-1) markedly inhibited the release of TNF-α and IL-6 and decreased NF-κB expression, compared with the model group. Moreover, the improved SOD activity and decreased MDA, LDH and CK levels were detected after AS IV treatment. In summary, AS IV could increase the activities of antioxidant enzymes, inhibite lipid peroxidation, and down-regulate the inflammatory mediators involved in the inflammatory responses. These results demonstrated that AS IV could prevent LPS-induced injury in cardiomyocytes.

Autophagy and prostate cancer / 中华男科学杂志

The role of autophagy is known to be highly complex and context-dependent, and may be characterized as both tumor suppression and tumor promotion in some tumors, such as breast cancer and prostate cancer. This review outlines recent advances in the studies of the involvement of autophagy in the development, progression and treatment of prostate cancer, focusing on autophagy modulation during androgen deprivation, with a special discussion on the regulatory effect of androgens on the autophagy of prostate cancer cells. A critical evaluation and analysis of the studies suggests that autophagy inhibition combined with androgen deprivation therapy is a promising approach to the treatment of prostate cancer.
