The association between atrial fibrillation (AF) after coronary artery bypass grafting (CABG) and the surgical techniques selected has been extensively reported.However,no consistent results were obtained.In the present study,a meta-analysis was conducted by searching the electronic databases PubMed,Embase,Web of Science,and Cochrane to identify the association of post-CABG AF with on-pump (conventional CABG,cCABG) or off-pump CABG (OPCABG).Outcomes from randomized clinical trials (RCTs) and propensity score matching (PSM) trials were pooled by using the fixed-effect or the random-effect modeling method,and verified by the quality-effect modeling method.There were 35 studies with 36 independent reports that met the inclusion criteria and were eventually included in our meta-analysis.The total odds ratio (OR) of the incidence of post-CABG AF between OPCABG and cCABG was 0.80 (95％ CI 0.71-0.91).The 25 randomized clinical trials (RCTs) had an OR of 0.69 (95％ CI 0.56-0.86),while the OR of the 11 PSM trials was 0.88 (95％ CI 0.77-1.00).Twenty-six studies involving the patients at a mean age no more than 65 years showed an OR of 0.76 (95％ CI 0.64-0.90),whereas 10 studies with patients greater than 65 years old showed an OR of 0.90 (95％ CI 0.78-1.05).The results of this meta-analysis suggest that OPCAB surgery may reduce the incidence of post-CABG AF when compared to cCABG and that younger patients may benefit more from OPCAB and have a lower incidence ofpost-CABG AF.

Objective To conduct isolation identification of hydrangenol and establish a method for content determination of hydrangenol in the leaves of Hedyotis hedyotidea (DC) Merr; To provide references for further development and research of Hedyotis hedyotidea;To compare the contents of hydrangenol in the leaves of Hedyotis hedyotidea of different production areas and different batches. Methods Hydrangenol showed a good linear relationship within the range of 0.412–10.300 μg (r=1.000 0), with the average recovery of 99.09% (RSD=0.53%). Good precision and repeatability were achieved with the RSDs smaller than 1.0%. The content range was 0.03%–0.38% for hydrangenol in the leaves of Hedyotis hedyotidea of different production areas and different batches, and the highest contents appeared in those from Guangxi. Conclusion The method is simple, accurate, specific, reproducible and can be used for the content determination of hydrangenol in the leaves of Hedyotis hedyotidea; the contents of hydrangenol in the leaves of Hedyotis hedyotidea of different production areas and different batches are different, and contents in samples from Guangxi and Guangdong are higher.

Objective To explore the caregiver burden and psychological resilience of patients with dilated cardiomyopathy and the correlation between the two factors.Methods Totally 96 caregivers of dilated cardiomyopathy patients were selected by convenience sampling and investigated for their level of burden and psychological resilience with the Caregiver Burden Inventory (CBI) and Conor-Davidson Resilience Scale (CD-RISC). The correlation between the two factors was then analyzed.Results The CBI score of these caregivers was (47.19±10.38), significantly higher than the average level nationwide (24.2±5.8). Their CD-RISC score was (63.07±13.18), lower than (65.4±13.9) of China's community population. There was apparent negative correlation between caregiver burden and psychological resilience (r=-0.62,P<0.01). The total score of resilience was negatively related to the burden of development constraint, social burden and emotional burden (r=-0.72, -0.65, -0.51;P<0.01).Conclusions The caregivers of dilated cardiomyopathy patients have a heavy burden, which is negatively correlated with their psychological resilience. Therefore, measures should be taken in clinical work to optimize the caregivers' psychological resilience, reduce their burden, and improve their quality of care.

OBJECTIVETo investigate the effects of endothelial microvesicles (EMVs) induced by calcium ionophore A23187 on H9c2 cardiomyocytes.

METHODSHuman umbilical vein endothelial cells (HUVECs) were treated with 10 micromol/L A23187 for 30 min. EMVs from HUVECs were isolated by ultracentrifugation from the conditioned culture medium. EMVs were characterized using 1 and 2 microm latex beads and anti-PE-CD144 antibody by flow cytometry. For functional research, EMVs at different concentrations were cocultured with H9c2 cardiomyocytes for 6 h. Cell viability of H9c2 cells and the activity of LDH leaked from H9c2 cells were tested by colorimetry. Moreover, apoptosis of H9c2 cells was observed through Hoechst 33258 staining and tested by FITC-Annexin V/PI double staining.

RESULTSEMVs were induced by A23187 on HUVECs, and isolated by ultracentrifugation. We identified the membrane vesicles (< 1 microm) induced by A23187 were CD144 positive. In addition, the EMVs could significantly reduce the viability of H9c2 cells, and increase LDH leakage from H9c2 cells in a dose dependent manner (P < 0.05). Condensed nuclei could be observed with the increasing concentrations of EMVs through Hoechst 33258 staining. Furthermore, increased apoptosis rates of H9c2 cells could be assessed through FITC-Annexin V/PI double staining by flow cytometry.

CONCLUSIONMicrovesicles could be released from HUVECs after induced by A23187 through calcium influx, and these EMVs exerted a pro-apoptotic effect on H9c2 cells by induction of apoptosis.

The metabolic effect of Fo-Shou-San on blood deficiency mice was studied by using metabolomic method. UPLC-QTOF/MS was used to analyze the plasma metabolome in blood deficiency mice. MS data were processed by MarkerLynx software. With multivariate statistical analysis of plasma metabolite profiles, a clear separation among control, blood deficiency model, and Fo-Shou-San groups was achieved. Potential biomarkers were selected according to the parameters of variable importance in the projection (VIP) and identified according to MS information and database retrieval. The metabolic network of blood deficiency was predicted via MetPA database. Twenty-two potential biomarkers were identified and used to explain the thiamine metabolism, arachidonic acid metabolism, sphingolipid metabolism, glyoxylate and dicarboxylate metabolism, histidine metabolism, nicotinate and nicotinamide metabolism, cysteine and methionine metabolism, tryptophan metabolism, starch and sucrose metabolism, tyrosine metabolism and citrate cycle (TCA cycle). Those metabolic pathways were disturbed in blood deficiency mice, but which could be regulated nearly to normal state after Fo-Shou-San administration. In this study, the metabolomics of blood deficiency mice and the action mechanism of nourishing blood effect of Fo-Shou-San were evaluated. The physiological and metabolic state of the organism could be represented comprehensively by using metabolomics. And metabolomics can be used to evaluate the pharmacodynamics and related mechanisms of Chinese medicine and formulae.
