Objective:To explore the level of physical activity of Chinese adults with haemophilia and its related factors so as to provide a reference for their comprehensive management.Methods:The daily physical activity of adults with haemophilia was surveyed using the International Physical Activity Questionnaire (IPAQ). A total of 110 questionnaires were eligible for analysis at last. The results were compared with published data from other societies using independent sample t-tests and chi squared tests. Spearman correlation analysis and multivariate logistic regression analysis were applied to explore factors related to the subjects′ physical activity levels.Results:Fully 30.9% of the subjects claimed to maintain a high level of physical activity. This was significantly different from the distribution of physical activity observed in Japan (12.4%), Ireland (50.9%) and the United Kingdom (43.1%). According to the Spearman correlation analysis, the number of joints affected, anxiety, and depression are all significantly related to the level of physical activity among such adults. Multivariate logistic regression analysis showed that depression was an independent factor affecting the patients′ level of physical activities.Conclusion:Chinese and Japanese adults with hemophilia have relatively low levels of physical activity, possibly influenced by depression.

OBJECTIVETo observe and evaluate the effect of tongxinluo capsule (TXL) on recovery of ventricular wall with segmental dyskinesia in patients with early stage acute myocardial infarction (AMI).

METHODSOne hundred and twelve AMI patients after percutaneous coronary intervention (PCI) or fibrinolytic therapy, were randomly divided into 2 groups, the control group (CG) treated with conventional medicine and the interfered group (IG) treated with conventional medicine plus TXL. The changes of ventricular wall motion, left ventricular end diastolic volume (LVEDV) and left ventricular ejection fraction (LVEF) were observed at different time points (1-w, 2-w, 1-m, 3-m and 6-m) after PCI by using two dimensional echocardiography (2DE).

RESULTSThe ventricular dyskinetic segment recovery rate at 1-w, 2-w, 1-m and 6-m in IG was 11.9%, 18.1%, 18.8% and 70.02% respectively, which was significantly higher than the respective rates in CG (4.1%, 8.3%, 11.1% and 51.68%, P < 0.01), but the 3-m recovery rate in the two groups was insignificantly different. LVEDV increase rate in the two groups at 1-w was insignificantly different, but it significantly increased at 2-w and 1-m, and showed a higher rate in CG (P < 0.05). However, at 3-m and 6-m, it significantly decreased in IG but was insignificantly changed in CG. Improvement of LVEF was insignificant at 1-w, 2-w and 1-m in both groups, but at 3-m and 6-m, LVEF was significantly improved in the interfered group (P < 0.01), but still showed no obvious change in the control group.

CONCLUSIONConventional western medicine combined with TXL can significantly decrease the infarction area, improve left ventricular diastolic function in patients with AMI.

OBJECTIVETo evaluate the change of endothelin-1 (ET-1) in the mini-swine model of acute myocardial infarction (AMI) and reperfusion and the effect of Tongxinluo (TXL) on it, and to explore the possible mechanism of no-reflow.

METHODSForty mini-swines were randomized into 5 groups: the model group, the small,middle and large dose of TXL groups and the sham-operated group, 8 in each group. The AMI reperfusion model was established by coronary ligation for 3 hrs followed with relaxation for 1 hr. Plasma ET-1 content before and after AMI, and after reperfusion was determined respectively by radioimmunoassay. The ET-1 mRNA expression in myocardial tissue of normal, ischemic and no-reflow area were respectively quantified by reverse transcription-polymerase chain reaction.

RESULTS(1) Compared with before AMI, levels of plasma ET-1 at the time points of 5 min and 3 hrs after AMI, 5 min and 1 hrs after reperfusion in the model group were significantly raised, showing an increasing tendency (all P < 0.01). But the increment in the middle and large dose of TXL groups were all lower than that in the model group (P < 0.05). (2) In the model and the TXL groups, levels of ET-1 in myocardial tissue of ischemic and no-reflow area were significantly higher than those in the normal area, and the increment in no-reflow area was higher than that in ischemic area (all P < 0.01). Compared with the model group, significant lowering of ET-1 in ischemic area was only shown in the middle and large dose of TXL groups (P < 0.01). (3) In the model and the TXL groups, ET-1 mRNA expression in ischemic area was significantly higher (all P < 0.01), while it in no-reflow area was significantly lower than that in the normal area respectively (all P < 0.01). The raised ET-1 mRNA expression in the middle and large dose TXL groups was significantly lowered when compared with that in the model group (P < 0.01).

CONCLUSIONThe endothelium injury might be one of the important mechanisms for no-reflow phenomenon. TXL might reduce the no-reflow by protecting endothelium cells. was significantly higher (all P < 0.01), while it in no-reflow area was significantly lower than that in the normal area respectively (all P < 0.01). The raised ET-1 mRNA expression in the middle and large dose TXL groups was significantly lowered when compared with that in the model group (P < 0.01). Conclusion The endothelium injury might be one of the important mechanisms for no-reflow phenomenon. TXL might reduce the no-reflow by protecting endothelium cells.
