Objectives To examine the effects of enhanced external counterpulsation on arterial elasticity in stroke patients to provide clinical evidence for secondary prevention of patients with cerebral ischemic stroke. Methods Total 192 patients with ischemic stroke were enrolled and then divided into the EECP (n=107) and control (n=85) group. Auto-matic measurement synchronous atherosclerosis detector was use to measure brachial-ankle pulse wave velocity (BaP-WV) and cardio-ankle vascular index (CAVI). The difference of BaPWV and CAVI were evaluated before, at 36 hours and one month after EECP. Results The BaPWV and CAVI significantly decreased at 36 hours and 1 month after treat-ment in EECP groups compared to either pre-therapy or control groups (all P<0.05). Conclusions EECP can signifi-cantly reduce the BaPWV and CAVI and improve the arterial elasticity in patients with cerebral ischemic stroke. Thus, arterial elasticity may be an important index to evaluate the effects of EECP on cerebral ischemic stroke.

ObjectiveTo assess negative risk factors associate with short-term and long-term poor outcome of acute heart failure syndromes(AHFS) and provide evidence to emergently proceed to AHFS low risk stratification.Methods A retrospective cohort study was conducted. 125 AHFS patients who met research criterion were enrolled from Guangxi Baise People's Hospital and Youjiang District People's Hospital of Baise City. The patients were divided into poor outcome and relatively low-risk groups by the results of short- and long-term follow-up of their outcomes. The patient's vital signs and disease history were collected at the first time after admission, and auxillary examination parameters were recorded. The poor outcomes occurring in the follow-up periods from the admission to after discharge for 30 days(short-term) and 1 year(long-term)were recorded, and Cox hazard regression was used to analyze the negative risk factor in the short- and long-term.Results There were 58 cases(46.4%)with poor outcome and 30 cases(24.0%)dead in short-term, and there were 111 cases(88.8%) with poor outcome and 39 cases(31.2%) dead in the long-term follow up. Seven negative risk factors were identified by Cox regression. They were no previous or de novo myocardial infarction〔short-term: hazard ratio(HR)=0.36, 95% confidence interval (95%CI)=0.20-0.65,P=0.001〕, lymphocyte ratio 0.20-0.40(short-term:HR=0.13, 95%CI=0.04-0.47, P=0.002; long-term:HR=0.42, 95%CI=0.26-0.68,P=0.001),oxygenation index(PaO2/FiO2)>300 mmHg (1 mmHg=0.133 kPa,short-term:HR=0.23, 95%CI=0.09-0.54,P=0.001),estimated glomerular filtration rate (eGFR)>60 mL·min-1·1.73 m-2(short-term:HR=0.31, 95%CI=0.16-0.64,P=0.002;long-term:HR=0.54, 95%CI=0.36-0.83,P=0.004),left ventricular ejection fraction(LVEF)>0.50(short-term:HR=0.29, 95%CI= 0.10-0.85,P=0.024), P wave terminal force in lead V1(PtfV1)>-0.04 mm·s(short-term:HR=0.29, 95%CI= 0.14-0.60,P=0.001), planar QRS-T angle<90°(long-term:HR=0.46, 95%CI=0.27-0.77,P=0.003). ConclusionsOur patients with AHFS cohort have very poor outcomes both in short-term and long-term follow up. Those with the following characteristics: no previous or de novo myocardial fraction, lymphocyte ratio 0.20-0.40, PaO2/FiO2>300 mmHg, eGFR>60 mL·min-1·1.73 m-2, PtfV1>-0.04 mm·s, LVEF>0.50 and planar QRS-T angle<90°are more likely to have optimal short-term and long-term outcome.

Objective To reveal the research trends and hotspots of China's liver neoplasms literature from 2005 to 2010. Methods A bibliometric analysis was made based on the results of retrieving from the Chinese Medical Citation Index (CMCI). Results The number of China' s liver neoplasms literature increased regularly in the last 5 years. The fund articles accounted for 30% of total articles. This paper reports the highly cited articles, authors, institutions and journals. The top 5 provinces of publishing articles are Guangdong, Shanghai, Jiangsu, Shandong and Beijing. There are some major aspects of liver neoplasms research, such as treatment modalities, analysis of causes of disease, evaluation after radiation therapy, and experimental research. 3-dimensional conformal radiotherapy, radiofrequency ablation and chemoembolization have been becoming research hotspots. Conclusions The researches on liver neoplasms have been widely and deeply developing in China. A lot of research progresses were made. As the higher mortality of liver neoplasms, the research of comprehensive treatment is to be the further trend.

In the present study, an ultra performance liquid chromatography coupled with time-of-fight mass spectrometry (UPLC-TOF/MS) based chemical profiling approach was used to evaluate chemical constitution between co-decoction and mixed decoction of ginseng and Radix Aconiti Praeparata. Two different kinds of decoctions, namely co-decoction of ginseng and Radix Aconiti Praeparata: water extract of mixed two herbs, and mixed decoction of ginseng and Radix Aconiti Praeparata: mixed water extract of each individual herbs, were prepared. Batches of these two kinds of decoction samples were subjected to UPLC-TOF/MS analysis. The datasets of t(R) m/z pairs, ion intensities and sample codes were processed with supervised partial least squared discriminant analysis (OPLS-DA) to holistically compare the difference between these two decoction samples. Significant difference between the two decoction samples was showed in the results of positive ion mode. The contents of hypaconitine and deoxyaconitine decreased, while that of benzoylmesaconine, benzoylhypaconine and dehydrated benzoylmesaconine increased in the samples of co-decoction of ginseng and Radix Aconiti Praeparata. The content of diester-diterpenoid alkaloids decreased, while that of monoester-diterpenoid alkaloids increased, which is probably the basis of toxicity-attenuated action when combined ginseng with Radix Aconiti Praeparata.

Objectives To explore the effects of enhanced external counterpulsation(EECP)on the serum level of C-reactive protein and endothelin-1 in patients with cerebral ischemic stroke,to provide clinical evidence for the treat?ment and secondary prevention of patients with cerebral ischemic stroke. Methods Total 187 patients with ischemic stroke were enrolled measure the serum level of C-reactive protein and endothelin-1, before EECP, after36 hours EECP, and one-month after EECP. Then contrast the difference of these indicators. Result After treatment, the serum levels of C-reactive protein and endothelin-1 in EECP group were obviously decrease and the difference was statistically signifi?cant(hs-CRP 60.1%vs. ET-1 40.9%,P<0.05). After treatment, the serum levels of C-reactive protein and endothelin-1 in EECP group were obviously decrease than that in the control group and the difference was statistically significant ( hs-CRP 41.3%vs. ET-1 24.3%,P<0.05). One-month after EECP, the serum level of endothelin-1 in EECP group was obviously decrease than that in the control group(43.8%vs. 31.8%,P<0.05). One-month after EECP, there was no signif?icant difference in the serum levels of C-reactive protein between the two groups (P>0.05). Conclusion EECP can obvi?ously reduce the serum levels of C-reactive protein and endothelin-1 in the patients with ischemic stroke, which indi?cates that EECP can slow atherosclerotic process.
