引用

Chinese Journal of Integrative Medicine 2017年第4期23卷 288-294页

作者： wang li-pei ZHAO Yan-na SUN Xin GAO Rui-lan College of Basic Medical Sciences Zhejiang Chinese Medical University Institution of Oncology Zhejiang Provincial People's Hospital

Objective To explore the effects of bufalin on inhibiting proliferation, up-regulating methylation of Wilm’ tumor 1 gene (WT1) as well as its possible mechanisms in human erythroid leukemic (HEL) cells. Methods The HEL cells were treated with bufalin at various concentrations to observe cellular morphology, proliferation assay and cell cycle. The mRNA and protein expression levels of WT1 were detected by reverse transcription polymerase chain reaction (RT-PCR), Western blot and immunocytochemistry, DNA methylation of WT1 and protein expression levels of DNA methyltransferase 3a (DNMT3a) and DNMT3b were analyzed by methylation-specific PCR, and Western blot respectively. Results The bufalin was effective to inhibit proliferation of HEL cells in a dose-dependent manner, their suppression rates were from 23.4%±2.1% to 87.2%±5.4% with an half maximal inhibit concentration (IC50) of 0.046 μmol/L. Typical apoptosis morphology was observed in bufalin-treated HEL cells. The proliferation index of cell cycle decreased from 76.4%±1.9% to 49.7%±1.3%. The expression levels of WT1 mRNA and its protein reduced gradually with increasing doses of bufalin, meanwhile, the methylation status of WT1 gene changed from unmethylated into partially or totally methylated. While, the expression levels of DNMT3a and DNMT3b protein gradually increased by bufalin treatment in a dose-dependent manner. Conclusions Bufalin can not only significantly inhibit the proliferation of HEL cells and arrest cell cycle at G0/G1 phase, but also induce cellular apoptosis and down-regulate the expression level of WT1. Our results provide the evidence of bufalin for anti-leukemia, its mechanism may involve in increasing WT1 methylation status which is related to the up-regulation of DNMT3a and DNMT3b proteins in erythroid leukemic HEL cells.

Temporal assembly patterns of microbial communities in three parallel bioreactors treating low-concentration coking wastewater with differing carbon source concentrations

Carbon source is an important factor of biological treatment systems, the effects of which on their temporal community assembly patterns are not sufficiently understood *** this study, the temporal dynamics and driving mechanisms of the communities in three parallel bioreactors for low-concentration coking wastewater(CWW) treatment with differing carbon source concentrations(S0 with no glucose addition, S1 with 200 mg/L glucose addition and S2 with 400 mg/L glucose addition) were comprehensively studied. Highthroughput sequencing and bioinformatics analyses including network analysis and Infer Community Assembly Mechanisms by Phylogenetic bin-based null model(iCAMP) were used. The communities of three systems showed turnover rates of 0.0029~0.0034 every 15days. Network analysis results showed that the S0 network showed higher positive correlation proportion(71.43%) and clustering coefficient(0.33), suggesting that carbon source shortage in S0 promoted interactions and cooperation of microbes. The neutral community model analysis showed that the immigration rate increased from 0.5247 in S0 to 0.6478in S2. The iCAMP analysis results showed that drift(45.89%) and homogeneous selection(31.68%) dominated in driving the assembly of all the investigated microbial *** contribution of homogeneous selection increased with the increase of carbon source concentrations, from 27.92% in S0 to 36.08% in S2. The OTUs participating in aerobic respiration and tricarboxylic acid(TCA) cycle were abundant among the bins mainly affected by deterministic processes, while those related to the metabolism of refractory organic pollutants in CWW such as alkanes, benzenes and phenols were abundant in the bins dominated by stochastic processes.

Objective： To evaluate the prognosis effect of Chinese herbal medicines（CHMs） for benefiting qi and activating blood circulation adjunctive to conventional treatment in patients with acute coronary syndrome（ACS） after percutaneous coronary intervention（PCI）. Methods： A total of 702 patients with ACS who underwent PCI were enrolled and randomly assigned to receive conventional treatment plus CHMs for benefiting qi and activating blood circulation（treatment group, 351 cases） or conventional treatment alone（control group, 351 cases） for 6 months. Six months later, all patients received conventional treatment alone. Follow-ups were scheduled at 6th, 12 th, 18 th, 24 th month after enrollment in April 2008, and the final follow-up visit was during September 2011 and November 2011. The primary endpoint was the composite of cardiac death, nonfatal myocardial infarction or revascularization（PCI or coronary artery bypass grafting）; and the secondary endpoint was the composite of re-admission for ACS, congestive heart failure, nonfatal stroke or other thrombus events. Results： A total of 621（88.59%） patients completed 35.4±3.8 months follow-up, while 80（11.41%） patients withdrew from the trial（41 in the treatment group and 39 in the control group）. The incidence of primary endpoint was 5.7%（20 patients） in the treatment group versus 10.86%（38 patients） in the control group [relative risk（RR）： 0.53; 95% confidence interval（CI）： 0.30, 0.88; P=0.013; absolute risk reduction（ARR）： –0.052, 95% CI： –0.06, 0.01]. The incidence of secondary endpoint was 5.98%（21 patients） in the treatment group versus 10.28%（36 patients） in control group（RR： 0.58, 95% CI： 0.33, 0.97, P=0.037; ARR： –0.043, 95% CI： 0.06, 0.01）. Most of the primary and secondary endpoints were occurred in 18 months（84.50% in the treatment group versus 78.10% in the control group）.
