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 explore the different changes of the adult cerebral blood flow with ages,different weight and gender,to summarize the changing characteristics of cerebral blood flow.Methods 360 cases of examination were divided into two groups according to gender,and were divided into five groups at different ages,and were divided into four groups according to body mass index,using TCD detector blood flow velocity.Results 196 cases of male physical examination,the mean cerebral blood flow was (969.37 ± 117.54)ml/min;the 164 females physical examination,the average cerebral blood flow was (987.76 ± 114.34)ml/min,there was no statistically significant difference (P ＞ 0.05).Different ages cerebral blood flow velocity were different,20 to 29-year-old group and the 30 to 39-year-old group had no significant difference (P ＞ 0.05) ;40 to 49-year-old group,50 to 59 years,60 to 69 years old ＞ 70 age group significantly declined compoued with the first two groups,there was significant difference (P ＜ 0.05) ;there were significant difference between the four groups (P ＜ 0.05).Overweight and obese group were significantly lower than the light and the normal group,there was a statistically significant difference (P ＜ 0.05).Conclusion TCDcan be a sensitive and accurate hemodynamic changes in the human brain,and is very important in the early diagnosis,prevention,treatment,and follow-up of cerebrovascular disease.

Objective To explore the therapeutic effect and prognosis of enhanced external counterpulsation (EECP)on acute cerebral ischemic stroke,to provide clinical evidence for the treatment of patients with acute cerebral ischemic stroke.Methods Total171 patients with acute cerebral ischemic stroke were enrolled and measured the NIHSS and mRS,before EECP,after36 hours EECP,and 3-month after attack.Then contrast the difference of these indicators.Result Compare with the control group,after EECP treatment and after 3-month attack,the scores of NIHSS were statistically significant,(after EECP:44.1％ vs 31.5％;after 3-month attack:55.6％ vs 40.5％),(P＜ 0.05).Compare with the control group,after 3-month attack,the score of mRS in EECP group was declined statistically significant,and the rate of favourable prognosis rise obviously (P＜0.05).Conclusion EECP can effectively improve neurological function and promote health and improve prognosis in the patients with acute cerebral ischemic stroke.

Objective To understand the children health care and the prevention of lead pollution in Panyu in the future by re-search on the detection result of blood lead from Panyu children during 2011 and 2012.Methods The detection of whole blood lead was by atomic absorption spectrometer from body examination in 6 308 children in Panyu Center Hospital be-tween 2011 and 2012:①The blood lead result from assigned children were divided into five age groups:infancy group (1~12 months,1 511 cases),toddler age group (1~2 years,1 558 cases),preschool age group (3~6 years,1 704 cases),school age group (7~11 years,1 076 cases)and adolescence group (12~18 years,459 cases).②Based on different age group,each group was separated by male and female.③According to the detection year,each group was also put into 2011 and 2012 re-spectively.Results The overall level of children blood lead in Panyu,Guangzhou in 2011 and 2012 was 37.01±29.18μg/L, and the total poisoning rate was 1.2 9%.Along with the growth of age,the overall level of children blood lead was in up-wards trend but the poisoning rate kept in a stable level beginning from infant stage.The blood lead level of boys in Panyu was 38.87±30.18μg/L,and the poisoning rate was 1.91%;the blood lead level of girls was 34.13±27.32μg/L,and the poisoning rate was 1.29%.The blood lead levels and the poisoning rates of boys were higher than girl’s in most of age groups.Conclusion Compared with other big cities like Guangzhou,the blood lead level of children in Panyu was declined but it’s not the standard performance,and there’s a certain extent of lead pollution.So in addition to reinforce pollution con-trol from government,parents and children should enhance the knowledge,education and precaution of lead poisoning.
