Heart failure (HF) is a severe heart disease. The use of autologous bone marrow stem cells (BMCs) mobilization in the treatment of HF has been a hot topic to research both in Western medicine and Chinese medicine (CM). There are many clinical trials and experiments on study of BMCs mobilization for HF therapy, including integrative medicine. The effect of BMCs mobilization is favorable for cardiac repair, while some advantages of CM support the advanced study of its application in BMCs mobilization to treat HF. In addition, with mechanisms of autologous BMCs mobilization for the treatment of HF that will be revealed in the future, especially stem cells niches, integrative medicine would play an important role in this clinical thought of therapy model gradually. Simultaneously, CM should adapt the new approaches of stem cells progresses on HF treatment as holding characteristics of itself.

OBJECTIVECompared with Shengmai Capsule (生脉胶囊, SM), the study was conducted to evaluate the efficacy and safety of Xuefu Zhuyu Capsule (血府逐瘀胶囊, XFZY) on the symptoms and signs and health-related quality of life (HR-QOL) in the unstable angina (UA) patients with blood-stasis syndrome (BSS) after percutaneous coronary intervention (PCI).
METHODSA randomized, double-blinded, double-dummy, and placebo-controlled trial was applied. Ninety patients, diagnosed as UA and BSS after successful PCI, were enrolled and equally randomized into three groups, XFZY group, SM group, and placebo group, and administered with the corresponding medications respectively for four weeks. The clinical symptoms and signs (CSS), electrocardiography (ECG), and BSS scores were recorded and compared among groups during and after the treatment. Short-form 36 (SF-36) and Seattle Angina Questionnaire (SAQ) were applied to assess the HR-QOL in each group before and after the treatment. Safety indexes (blood routine and liver and kidney function tests) were also examined at the beginning and after the treatment.
RESULTSEighty-six patients completed the whole study. After the treatment, the total effective rates of the XFZY group in ameliorating CSS and ECG were 76.7% and 60.0%, respectively, which were obviously higher than those in SM (CSS: 53.3%; ECG: 36.7%) and the placebo (CSS: 43.3%; ECG: 30.0%) groups. After one week's treatment, BSS scores slightly decreased in each group, but no significant differences were found among three groups (P>0.05). After four weeks' treatment, BSS scores in the XFZY group decreased to a lower level compared with SM (P <0.05) and the placebo (P <0.01) groups. After the treatment, the efficacy of XFZY group in improving body pain (BP), general health (GH), vitality (VT), society functioning (SF), role emotional (RE), angina stability (AS), angina frequency (AF), and treatment satisfaction (TS) were better than those in the placebo group (P <0.05,P <0.01). Meanwhile, the dimensions of BP, GH, SF, AS, AF, and TS were better improved than those in the SM group P <0.05). No obvious adverse reaction was found during and after the treatment except one case in the XFZY group reporting of stomach discomfort.
CONCLUSIONSCompared with SM Capsule treatment, a short-term treatment with XFZY Capsule exhibits better efficacy on CSS and BSS scores, and HR-QOL in UA patients with BSS after PCI. However, its long-term efficacy and safety still needs further investigation.

OBJECTIVE: To evaluate the relationship between serum levels of soluble Fas(sFas), soluble Fas li gand(sFasL), soluble IL-2 receptor(sIL-2R) and coronary heart disease (CHD). METHODS: With enzyme-linked immunosorbent assay (ELISA) tests, sFas, sFasL and sIL-2R were measured in the sera from 30 patients with CHD and 26 subjects without CHD as controls. RESTULTS: Mean level of sFas was significantly higher in patients with CHD than in controls [(1 583.41+/-174.46)ng/L compared with (1 374.55+/-142.42)ng/L, P<0.01]. Compared with the controls, the mean level of sIL-2R was significantly higher in patients with CHD [(944.50+/-395.59)ng/L compared with (652.45+/-163.36)ng/L P<0.01]. Moreover, in patients with CHD sFas and sIL-2R were positively correlated (r=0.418 P<0.05). Whereas no such difference was found between both groups in sFasL (P<0.05). CONCLUSION: High levels of serum sFas and sIL-2R were associated with CHD, and elevation of sFas may inhibit apoptosis in activated T cells, leading to coronary events.

To look for the toxicity fraction of Euphorbia pekinensis and discuss the vinegar processing mechanism. The level of intestinal edema, water content of intestine and stool, IC50 values of IEC-6 were applied to evaluate the toxicity of different fractions. RT-PCR was employed for detecting AQP1, AQP3 mRNA expression. The petroleum ether (PE) fraction and ethyl acetate (EtOAc) fraction could significant cause intestinal edema in mice, increase the water content of duodenum, colon and stool, inhibited the mRNA expression of AQP1 and increased the mRNA level of AQP3 in colon, and the petroleum ether (PE) fraction was more poisonous. After the petroleum ether (PE) fraction was processed with vinegar, the level of intestinal edema, water content of duodenum, colon, stool and inhibition ratio of cells line were reduced. And we compared the composition change after vinegar processing, finding that the conpekinensis.

BACKGROUNDCurrent evidence links atrial fibrillation (AF) to the inflammation. Inflammatory indexes such as high-sensitive C-reactive protein (hs-CRP) have been related to the development and persistence of AF. However, the role of inflammation in the atrial electrophysiological remodeling indexed by P-wave dispersion (P d ) remains unclear.
METHODSThe study consisted of 71 patients with lone paroxysmal AF (AF group) and 71 age- and gender-matched controls of paroxysmal supraventricular tachycardia without history of AF (control group). Electrocardiography, P d , hs-CRP, and other clinical characteristics were compared between the two groups.
RESULTSThere was no significant difference between the two groups regarding age, gender, hyperlipidemia, etc. Compared to controls, left atrial diameter (44 ± 7 vs 39 ± 7 mm), P d (49 ± 13 vs 26 ± 8 ms), and hs-CRP (2.17 [1.46-2.89] vs 1.12 [0.74-1.41] mg/L) were increased (P < 0.05), respectively. Linear regression identified hs-CRP as an independent correlation of P d level both in the total population and the AF group (r = 0.464 and 0.313; P < 0.001, respectively). Multiple logistic regression revealed hs-CRP as an independent determinant of AF (odds ratio [OR] =15.430, 95% confidence interval: 6.031-39.476: P <0.001). Further adjusted for P d , both P d and hs-CRP were independent predictors for AF, but the OR for hs-CRP in predicting AF has been attenuated from 15.430 to 6.246.
CONCLUSIONSIn lone AF, P d and plasma hs-CRP concentration are inter-associated and related to AF. The interaction between hs-CRP and AF may be mediated by P d , suggesting an important role of inflammation in the atrial electrophysiological remodeling predisposing to AF.
