ABSTRACT
Along with the further aging of Chinese population,the number of elderly patients with heart failure is mounting rapidly,while hemodynamic monitoring plays an important role in the treatment of elderly patients with complex hemodynamic states and multiple diseases.Pulse indicated continuous cardiac output (PICCO) can quickly,effectively,continuously and safely perform hemodynamic monitoring and guide precise treatment,which is of great practical significance for improving the quality of life,prognosis and prolonging the effective life time of elderly patients with heart failure.This article reviews the characteristics of senile heart failure,the clinical application,safety and characteristics of PICCO.

Pulse indicated continuous cardiac output (PICCO) can quickly, effectively, continuously and safely perform hemodynamic monitoring and guide precise treatment, which is of great practical significance for improving the quality of life, prognosis and prolonging the effective life time of elderly patients with heart failure. This article reviews the characteristics of senile heart failure, the clinical application, safety and characteristics of PICCO.
ABSTRACT
Objective: To assess the clinical significance of peripheral blood levels of erythrocyte micro-particles on acute coronary syndrome (ACS) diagnosis. Methods: A total of 150 patients treated in our hospital from 2015-01 to 2016-09 were enrolled in this study. The patients were divided into 2 groups: Non-CAD (coronary artery disease) group, n=45 and ACS group, n=105. ACS group was further divided into 3 subgroups: STEMI (acute ST-segment elevation myocardial infarction) subgroup, n=37, Non-STEMI subgroup, n=31 and UAP (Unstable angina pectoris) subgroup, n=37. Peripheral blood sample was collected, erythrocyte micro-particles were separated by Ca2+ vector A23187 method and relevant micro-particles were labeled by specific antibody (glycophorine A) for qualitative and quantitative flow cytometry analysis. Results: Compared with Non-CAD group, ACS group had the higher peripheral level of erythrocyte micro-particles [％, 26.20 (15.90, 38.00) vs 14.00 (4.35, 36.35), P<0.05]. In ACS group, erythrocyte micro-particles were similar among 3 subgroups: in STEMI subgroup [％, 27.20 (17.25, 24.25)], in Non-STEMI subgroup [％, 21.50 (12.76, 34.90)] and in UAP subgroup [％, 30.20 (17.10, 39.65)], P>0.05. Conclusion: Peripheral blood levels of erythrocyte micro-particles were elevated in ACS patients which implied it may involve ACS development and could be related to acute thrombosis event in ACS patients.
ABSTRACT
Objective To investigate the the level of red blood cell microparticls in patients with acute coronary syndromes and the correlation with severity of coronary artery disease and with its influencing factors.Methods A total of 140 patients were sdected into our study from Jun 2016 to Feb 2017.All patiens were identified through coronary angiography.There were 108 patients with acute coronary syndromes (ACS) mentioned as experimental group,which including 25 patients with single vessel disease,27 patients with double vessel disease,27 patients with triple vessel disease and 29 cases of multi-vessel disease,and 32 patients of non-coronary heart disease group mentioned as control group.Each patient was fasting and drawn the periheral venous blood after the next day of hospitalized then analyzing blood lipids,blood routine and biochemical indicators.The expression of CD235a in erythrocyte derived microparticles was quantitatively analyzed by flow cytometry.The Gensini score was calculated based on the Results of coronary angiography.Results Compared with the non-CHD group,the levels of red blood cells microparticles (44.37％ ± 15.48％),low density lipoprotein cholesterol (3.18 ± 1.16mg/L),lipoprotein a (215.23 ± 183.10mg/L) and high sensitivity C Protein (19.58 ± 26.94mg/L) were significantly increased,and the difference was statistically significant (P ＜ 0.05).The levels of erythrocyte microparticles and low-density lipoprotein cholesterol in the subgroups of acute coronary syndromes were statistically significant (P ＜ 0.05),with erythrocyte microparticles levels and low-density lipoprotein cholesterol levels (P ＜ 0.05).There was a positive correlation between Gensini score and erythrocyte drived microparticls (β =2.157,P ＜ 0.05),and negatively correlated with high density lipoprotein (β =-15.579,P ＜ 0.05).Conclusion The level of Gensini scores were calculated based on the results of coronary angiography.That in patients with acute coronary syndrome is significantly higher than that in patients with non-coronary heart disease.The level of erythrocyte derived microparticls is closely related to the severity of coronary artery disease.The level of erythrocyte derived microparticls has a high value in predicting the severity of coronary artery disease in acute coronary syndromes.
ABSTRACT
Objective To evaluate the effect of prophylactic intra-aortic balloon pump (IABP) on reduction of the incidence of major adverse cardiovascular events (MACE) occurred during perioperativeperiod.Methods A total of 246 high-risk patients with AMI admitted from October 2013 through October 2016 were divided into two groups:prophylactic IABP group (n =144) and remedial IABP group (n =102).The likely complications associated with IABP were observed such as dissecting aneurysm,thrombocytopenia,lower extremity thrombosis,anemia,hematoma at puncture site.The comparison of postoperative heart failure,cardiogenic shock and refractory arrhythmia,and nosocomial death between two groups was carried out.The difference in length of time for treatment with IABP between two groups was compared.Statistical analysis of measurement data expressed in (x) ± s using independent sample t test.Countdata expressed in percentage were compared with chi-square test.Non-normal distribution data were checked with median ± interquartile range.P ＜ 0.05 for the difference was concerned statistically significant.Results Gensini score was higher in prophylactic IABP group (t =2.311,P ＜ 0.05).In remedial IABP group,the operative time was longer (t =2.626,P ＜ 0.05),the higher rate of using therapeutic medicine was significant (x2 =60.105,P ＜0.01),the no reflow rate was higher (x2 =19.920,P ＜0.01),the amount of contrast agent used was greater (t =2.437,P ＜ 0.05),the in-hospital incidence of heart failure was higher (x2 =31.638,P ＜ 0.01),the rate of nosocomial postoperative cardiogenic shock was higher (x2 =7.793,P ＜0.01),and the number of in-hospital death increased (x2 =4.827,P ＜ 0.05).Compared with prophylactic IABP group,higher BNP (t =7.44 7,P ＜ 0.05),and lower LVEF (t =3.557,P ＜ 0.05)were found in remedial IABP group.Conculsion Prophylactic employment of IABP for the treatment of high-risk AMI patients effectively improved the survival rate and reduced peri-opearative MACE.
ABSTRACT
Objective Sequence variations in mitochondrial DNA genes have been found to influence successful aging and longevity. The aim of this study was to examine whether mitochondrial DNA polymorphisms influenced the longevity in Chinese Uygur population.Methods We genotyped the mt5178A and mt10398G in 277 sampels representing three age group (centenarian, n=65; longevity, n=100; controls, n=112) from Taklimakan desert Uygur centenarians,China Results The distribution frequency of the 5178A in the centenarian (51/65, 78.5%) is slightly higher than in those of controls (63/112,56.3%,P=0.0029) . The frequency of the 10398G were significantly higher among the centenarian(47/65,72.3%)and longevity(68/100,68%) in comparison to the controls(60/112,53.6%,P
