Objective To evaluate the effect of recominant human growth hormone(rhGH) in the prevention and treatment of endotoxemia(ETM) in murine experimental obstructive jaundice (OJ) Methods Twenty OJ rats received subcutaneously given rhGH of 0 75*!IU/kg daily for 2 weeks (rhGH group). Blood endotoxin(ET) was measured, and intestinal mucosa was observed under electron microscope at 5th week.Results In rhGH group, ET level 〔(0 40?0 02)*!EU/ml〕 was significantly lower than OJ rats〔(0 77?0 03)*!EU/ml, n =20〕 ( t = 6 237, P 0 05). Under electron microscope bowel villi in OJ group were distroyed, epithelial cells were degenerated and necrotic, whereas in rhGH group the ultrastructural pathology was much less evident and similar to that in sham operation rats. Conclusion rhGH has significant effect on protecting the injured mucosa barrier in OJ,and decreases ETM significantly.

Objective Study on the spread and the development history of traditional Chinese medicine in Africa, as well as the present situation and trend, provide reference for better promoting China-Africa cooperation of traditional Chinese medicine. Methods Literature review and historical research methods are used to retrospect the process of traditional Chinese medicine into Africa, and analyze the typical event. Results traditional Chinese medicine was introduced into Africa's history dates back to the period of Zheng He's voyage. In 1963, China sent medical teams to Africa, the TCM comprehensive spread in Africa started. In 2005, China sent the first group of traditional Chinese medicine volunteers to Africa, which a new pattern of TCM spread. Conclusions By sending the medical teams, volunteers, and education training, academic conferences, traditional Chinese medicine was gradually known by the African people. TCM is developing rapidly by the supporting of the government. The opportunity should be seized to promote the comprehensive development of traditional Chinese medicine in Africa.

Objective To study the effect of recombinant human growth hormone(rhgh) on the expressions of tumor necrosis factor a(TNFa) and endotoxemia in murine experimental obstructive jaundice(OJ) models.Methods Sixty adult male wistar rats.were randomly divided into three groups A: sham operation group(SO),20;B:OJ group,20;C: OJ+rhGH group,20.The rats in group OJ and OJ+rhGH suffered from bile duct ligation,while the SO group did not.Two weeks later,rats in OJ+rhGH group were injected with rhGH subcutaneously once a day.The dose was 0.75 Iu/kg.The other two groups were injected with the same amount of saline.The endotoxin(ETX),the liver function and TNFa were detected four weeks later.Result The level of ETX(0.036?0.010EU/m1) and TNFa(182.00?88.37lpg/ml) in OJ+rhGH were much lower than those in OJ group(0.065?0.011EU/m1 P

Objective To investigate the factors associated with delay in decision to seek treatment in patients with acute myocardial infarction(AMI) in Beijing. Methods This prospective,cross-sectional,multicenter survey was conducted from November 1,2005 and December 31 ,2006. The participants consisted of 799 patients with STEMI admitted within 24 h of symptom onset to 19 hospitals in Beijing. Data were collected by semi-structured interviews and medical records review. The patients were categorized into an early decision group and the a late decision group based on the 30 min cut-off. Results The median(25%,75%) decision delay in STEMI patients was 60(20, 180)min. Factors associated with late decision in an univariate analysis were age ≥65 years, retirement or unemployment, history of myocardial infarction,symptom onset at home and intermittent symptoms, whereas presence of bystanders such as friends,coworkers or even strangers,unbearable symptoms,dyspnea,sweating,syncope and attribution of symptoms to cardiac origin were related to early decision. Multivariate logistic analysis showed that history of myocardial infarction,absence of syncope, intermittent symptoms,bearable symptoms and attribution of symptoms to noncardiac origin were independent predictors of decision delay＞30 min. Patients in the early decision group had more chances to receive acute reperfusion therapies(P=0.001) and shorter time intervals from symptom onset to reperfusion therapies(P＜0.001). Conclusions To a great extent patients with AMI in Beijing delayed in decision to seek treatment. History of myocardial infarction, symptom characteristics and symptom attribution were associated with decision delay.

Objective To evaluate the gender difference in the prognostic value of admission renal dysfunction (RD) for patients with acute ST-segment elevation (STEMI).Methods This was a multicenter,prospective cohort study.Four hundred and fifty STEMI patients within 24 h of onset and discharged successfully from 19 hospitals in Beijing were included in the study.All the patients were followed up six years later.According to gender,patients were categorized into two groups.Clinical characteristics,reperfusion therapy conditions and outcomes were analyzed.Multivariate Cox regression analysis was used to evaluate the possible gender difference in the prognostic value of RD.Results Among all the subjects,342 were men and 108 were women with age of (61.3 ± 12.5) years.Compared to man patients,women were older (P ＜ 0.001),and more subjects were with hypertension (67.6％ vs 49.7 ％,P =0.005),stroke (15.7％ vs 8.8％,P =0.039) and RD (17.9％ vs 6.7％,P =0.001).After adjustment of age,past medical history,and acute reperfusion therapy.Cox regression analysis showed that RD was associated with the risk of all-cause mortality (HR 3.771,95％ CI 1.382-10.294,P =0.010) and major adverse cardiovascular events (MACE,HR 2.292,95％ CI:1.091-4.817,P =0.029) in male patients.However,the associations between RD and all-cause mortality(HR 0.889,95％ CI 0.241-3.281,P =0.859),and MACE(HR 1.508,95％ CI 0.616-3.693,P =0.368)were disappeared in women.The interaction test showed that there existed significant interactions between gender and RD in all-cause mortality(HR 2.709,95％CI 1.150-6.384,P =0.023)and MACE(HR 1.977,95％ CI 1.009-3.876,P =0.023).Conclusions There is a considerable gender difference in the prognostic value of RD for the outcomes in patients with STEMI.RD seemed to be an important prognostic maker in male patients.

Objective To investigate impact of admission renal dysfunction on in-hospital and longterm outcome of patients with ST-elevation myocardial infarction (STEMI).Methods This was a multicentre,observational,prospective-cohort study.Totally 718 consecutive patients were admitted to 19 hospitals in Beijing within 24 hours of onset of STEMI.Estimation of glomerular filtration rate (eGFR) was calculated according to the abbreviated MDRD equation.The patients were categorized into two groups as renal preservation group(eGFR ≥60 ml · min-1 · 1.73 m-2) and renal dysfunction group(eGFR ＜ 60 ml ·min-1 · 1.73 m-2).The association between admission renal dysfunction and in-hospital and six-year outcome was evaluated.Results A total of 718 patients with STEMI were evaluated.There were 551 men and 167 women with age of (61.0 ± 13.0) years.One hundred and thirty-three patients(18.5％) had renal dysfunction.Patients with renal dysfunction were more often female and older,more patients had hypertension,diabetes and heart failure,and more patients had ≥ Killip Ⅱ classes on admission.These patients were less likely to present with chest pain.The in-hospital mortality(16.5％ vs 2.6％,P＜0.001),major adverse cardiac events(MACE) (60.9％ vs 24.4％,P ＜0.001),six-year all-cause mortality(35.3％vs 11.4％,P ＜ 0.001),six-year cardiac mortality (15.9％ vs 5.7％,P =0.001) and six-year MACE (52.4％ vs 28.0％,P ＜ 0.001)were markedly increased in renal dysfunction group than in renal preservation group.After adjusting for other confounding factors,renal dysfunction was an independent predictor of in-hospital MACE (OR 2.120,95％ CI 1.563-2.878,P =0.003),six-year all-cause mortality (RR 2.122,95％ CI 1.127-3.996,P =0.020) and six-year MACE(RR 1.586,95％ CI 1.003-2.530,P =0.047).Conclusions The mortality and MACE in STEMI patients with renal dysfunction were higher than in those with preserved renal function.Renal dysfunction evaluated by eGFR on admission is an important independent predictor of short-term and long-term outcome in patients with acute STEMI.

Objective: To explore the gender related differences of clinical symptoms and triggering factors in patients with acute myocardial infarction (AMI) in China.
Methods: A population of 14 854 AMI patients with CAMI registration from 2013-01 to 2014-03 were studied, which included 10999 (74.0%) male and 3855 (26.0%) female. The gender related differences of clinical symptoms and triggering factors were analyzed in the population.
Results: The chest pain and severe sweating were the most common symptoms of AMI patient, there were 66.4%of patients with persistent chest pain and 63.7%of patients with severe sweating. Male patients were more with chest pain (67.8%vs 62.4%) and severe sweating (65.8%vs 58.0%) than female, while female patients were more with radiating pain (36.0%vs 31.0%) and nausea/vomiting (35.6%vs 25.0%) than male, all P<0.05. There were 19.4%of patients having clear cause of AMI, and physical stress was the most frequent trigger (48.5%) for AMI. Male patients usually had clear cause than female (20.9%vs 15.1%), especially because of physical stress (49.5%vs 44.5%) and excessive recent unhealthy lifestyles (15.4%vs 8.8%), all P<0.05.
Conclusion: Chest pain and severe sweating were the most common clinical symptoms for AMI patients in China, about 1/5 of them had triggering factors and it was more in male patients.

BACKGROUNDNumerous previous studies have shown that renal insufficiency (RI) in patients with acute coronary syndrome is associated with poor cardiovascular outcomes. These studies do not well address the impact of RI on the long-term outcome of patients with acute ST-elevation myocardial infarction (STEMI) in China. The aim of this study was to investigate the association of admission RI and inhospital and long-term mortality of patients with acute STEMI.

METHODSThis was a multicenter, observational, prospective-cohort study. 718 consecutive patients were admitted to 19 hospitals in Beijing within 24 hours of onset of STEMI, between January 1,2006 and December 31,2006. Estimation of glomerular filtration rate (eGFR) was calculated using the modified abbreviated modification of diet in renal disease equation-based on the Chinese chronic kidney disease patients. The patients were categorized according to eGFR, as normal renal dysfunction (eGFR ≥ 90 ml·min -1·1.73 m -2 ), mild RI (60 ml·min -1·1.73 m -2 ≤ eGFR < 90 ml·min -1·1.73 m -2 ) and moderate or severe RI (eGFR < 60 ml·min -1·1.73 m -2 ). The association between RI and inhospital and 6-year mortality of was evaluated.

RESULTSSeven hundred and eighteen patients with STEMI were evaluated. There were 551 men and 167 women with a mean age of 61.0 ± 13.0 years. Two hundred and eighty patients (39.0%) had RI, in which 61 patients (8.5%) reached the level of moderate or severe RI. Patients with RI were more often female, elderly, hypertensive, and more patients had heart failure and stroke with higher killip class. Patients with RI were less likely to present with chest pain. The inhospital mortality (1.4% vs. 5.9% vs. 22.9%, P < 0.001), 6-year all-cause mortality (9.5% vs. 19.8 vs. 45.2%, P < 0.001) and 6-year cardiac mortality (2.9% vs. 12.2% vs. 23.8%, P < 0.001) were markedly increased in patients with RI. After adjusting for other confounding factors, classification of admission renal function was an independent predictor of inhospital mortality (Odd ratio, 1.966; 95% confidence interval [CI], 1.002-3.070, P = 0.019), 6-year all-cause mortality (relative risk [RR] = 1.501, 95% CI: 1.018-4.373, P = 0.039) and 6-year cardiac mortality (RR = 1.663, 95% CI: 1.122-4.617, P = 0.042).

CONCLUSIONSRI is very common in STEMI patients. RI evaluated by eGFR is an important independent predictor of short-term and long-term outcome in patients with acute STEMI.

Objectives:To investigate the clinical impacts of chronic total occlusion (CTO) in acute non-ST segment elevation myocardial infarction (NSTEMI) patients underwent primary percutaneous coronary intervention (PCI).Methods:A total of 2 271 acute NSTEMI patients underwent primary PCI from China Acute Myocardial Infarction Registry were enrolled in this study and divided into the CTO group and the non-CTO group according to the angiography. The primary endpoint was in-hospital mortality and mortality during a 2-year follow-up. The secondary endpoint was major adverse cardiovascular events (MACE) including revascularization, death, re-myocardial infarction, heart failure readmission, stroke and major bleeding.Results:Thirteen-point four percent of the total acute NSTEMI patients had concurrent CTO. In-hospital mortality (3.6% vs. 1.4%, P<0.01) and 2-year mortality (9.0% vs. 5.1%, P<0.01) were significantly higher in the CTO group than those in the non-CTO group, respectively. Multiple regression analyses showed that chronic obstructive pulmonary disease ( HR 7.28, 95% CI 1.50-35.35, P=0.01) was an independent risk factor of in-hospital mortality, and advanced age ( HR 1.04, 95% CI 1.01-1.07, P<0.01), and low levels of ejection fraction ( HR 0.95, 95% CI 0.93-0.98, P<0.01) were independent risk factors of 2-year mortality. CTO ( HR1.67, 95% CI 1.10-2.54, P=0.02) was an independent risk factor of revascularization, but not a risk factor of mortality. Conclusions:Although acute NSTEMI patients concurrent with CTO had higher mortality, CTO was only an independent risk factor of revascularization, but not of mortality. Advanced age and low levels of ejection fraction were independent risk factors of long-term death among acute NSTEMI patients.
