RESUMEN
Objective To understand the current situation and trend on the relations between erectile dysfunction (ED) and cardiovascular disease (CVD) through analyzing the epidemiologic research data.Methods We conducted a literature search on the Scopus for potentially relevant epidemiologic studies on ED and CVD published from 1957 to October,28,2016.Age of the article,types,regions,citation,and co-authorship of the documents were recorded.Results A total number of 412 pieces of literature were published in the past six decades,with original articles the most common types of ED and CVD.ED and CVD associated epidemiologic topics had an annual increase in number,and remained stable in the past decade,with occident countries as the United States and Italy taking the lead in this area.Clinical and epidemiological studies were the hottest areas,with most authors sharing a co-authorship.Conclusion Our results suggested that inter-disciplinary cooperation with emphasize on clinical application were the effective starting points for ED and CVD associated epidemiologic studies.

RESUMEN
Objective: To analyze long-term therapeutic effect and safety of warfarin anticoagulant therapy of different intensity on aged patients with nonvalvular atrial fibrillation (NVAF). Methods: According to age, a total of 197 NVAF patients followed up for five years were divided into advanced aged group [n=65，≥80(85±2.09)years], aged group [n=75, 65-79(76.5±2.27) years] and middle-aged group [n=57, ＜65(57.4±2.18)]. All enrolled patients received long-term warfarin anticoagulant therapy, advanced aged group and aged group received low intensity anticoagulation, international normalized ratio (INR) was 1.6~2.5, while middle-aged group received standard intensity anticoagulation and the INR was 2.0~3.0. Thrombus events and incidence rates of hemorrhage etc. over five years were compared among three groups, and the safe dose range of warfarin was explored. Results: During five-year follow-up, no acute cerebral infarction occurred in three groups. The bleeding and other adverse reaction among three groups were no significant difference（P＞0.05). Compared with middle-aged group, there were significant reductions in warfarin dose [(3.29±0.49) mg/d vs. (2.95±0.38) mg/d, (2.85±0.49) mg/d],INR [(2.54±0.43) vs. (2.20±0.29), (2.16±0.32)] and CHA2DS2-VASc [(3.02±0.89) score vs.( 2.64±0.77) score vs.( 2.33±0.48) score]in aged group and advanced aged group, P＜0.01 all; but there were no significant difference between aged group and advanced aged group (P>0.05). There were no significant difference in incidence rates of mild hemorrhage (21.1% vs. 14.7% vs. 24.6%) and severe hemorrhage (1.8% vs. 1.3% vs. 1.5%) among middle-aged group, aged group and advanced aged group, P>0.05 all. Conclusion: When INR is closely monitored, INR controlled within 1.6~2.5, warfarin anticoagulation is safe and effective in aged patients with nonvalvular atrial fibrillation.

RESUMEN
Objective To investigate the association between left ventricular diastolic function and arterial stiffness in patients with type 2 diabetes mellitus. Methods One hundred and two patients with type 2 diabetes( diabetic group),and 126 non-diabetic patients( control group) were selected from Jan. 2012 to Dec. 2013 in the Beijing Military General Hospital. The clinical features were recorded and free blood glucose (FBG ),blood lipids were measured. Cardio ankle vascular index( CAVI ) was measured by VS-1000 arteriosclerosis detector. Ultrasound heartbeat diagram was used to determine the left ventricular diastolic function indexes including the left atrial diameter(LAD),left ventricular early diastolicpeak velocity(E),left ventricular diastolic peak velocity(A),E/ A ratio and E peak deceleration time(EDT). Results The level of LAD,A, EDT,CAVI in diabetic patients were(39. 5 ± 5. 3)mm,(76. 6 ± 13. 5)cm/ s,(206. 6 ± 56. 3)ms,(9. 6 ± 1. 1)respectively,higher than those in control group((34. 4 ± 4. 2)mm,(71. 3 ± 13. 4)cm/ s,(185. 5 ± 34. 4)ms,(8. 5 ± 0. 9)). And E,E/ A level in diabetic group were(56. 6 ± 20. 4)cm/ s and(0. 73 ± 0. 21),significantly lower than the control group((67. 5 ± 16. 4)cm/ s and(0. 96 ± 0. 26)). The differences between the two groups were significant(P = 0. 001,0. 004,0. 002,0. 001,0. 001,0. 001). After adjusting the factors including body mass index and triglyceride,CAVI was negatively correlated with E/ A(r = - 0. 339,P< 0. 05))and positively correlated with EDT(r = 0. 314,P < 0. 05). Conclusion The diabetic patients with lower diastolic function and higher arterial stiffness,and the two factors are negatively correlation.
RESUMEN
ObjectiveTo study the association between cardio-ankle vascular index (CAVI) and carotid atherosclerosis as well as the risk factors in patients with type 2 diabetes mellitus.MethodsSixty type2 diabetic patients and 60 non-diabetic patients at the same hospitalization period were selected.The clinical features,laboratory test results such as free blood glucose ( FBG),blood lipids and other biochemical markers were recorded.Carotid intima-media thickness (IMT) and CAVI were measured.The relationship between CAVI and carotid atherosclerosis were analyzed; a multivariate linear regression analysis was performed between CAVI and risk factors of type 2 diabetes mellitus.ResultsThe body mass index,triglycerides,FBG,HbA1 c,IMT,the incidence of carotid artery plaque and CAVI values of diabetic group were significantly higher than that of nondiabetic group.Difference between the two groups was statistically significant ( all P ＜ 0.05 ) ; CAVI and carotid IMT was significantly correlated to each other( r =0.435,P ＜ 0.01 ) ; Multiple linear regression analysis showed that CAVI was significantly correlated to age (β =0.458,P ＜0.01 ),triglycerides (β =0.058,P =0.012),FBG (β =0.168,P =0.002) and HbAlc (β =0.228,P =0.003).ConclusionCAVI inpatients with diabetes was positively correlated with carotid IMT.Age,diabetes,triglycerides,FBG and HbAlc are independent risk factors for arterial stiffness.
RESUMEN
Objective To explore the prognosis value of serum hydrogen sulfide (H2S) concentration and acute physiology and chronic health evaluation HI (APACHE Ⅲ) scores in critically ill patients. Methods The serum H2S levels were measured in 72 cases and 12 controls by spectrophotometry. The APACHE Ⅲ scores of the patients were assessed. The relationship between serum H2S concentration and APACHE H scores and prognosis were analyzed. Results The average serum H2S concentration of the 72 cases was (45. 6 ±17.2) μmol/L The concentration in the survival group was(41. 1 ± 14. 7) μmol/L,and which was significantly lower than in the dead group(62. 8 ±15. 5)μmol/L,(P<0. 01). The average APACHE I score was(43. 6 ±26. 0)of the 72 cases. The APACHE Ⅲ score was(37. 7 ±22. 2) in the survival group,and which was significantly lower than in the dead group (65. 0 ±29. 6) (P <0. 01). The higher of the serum H2S concentration or APACHE Ⅲ scores,the higher mortality of the patients(P <0. 01). Conclusions Serum H2S levels and APACHE Ⅲ scores of critically ill patients have a role in judging the condition and prognosis of the patients.
RESUMEN
Objective:To observe the effect of "Qishen Yiqi Droplet" on serum concentrations of high sensitivity C reactive protein(hs-CRP),plasminogen activator inhibitor-1(PAI-1),endothelin-1(ET-1)in patients with acute coronary syndrome(ACS)after percutaneous coronary intervention (PCI).Methods:A total of 100 consecutive ACS patients ready to receive PCI therapy in our hospital from june 2007 to August 2008 were randomly assigned into two groups:Qishen group,n=50,with Qishen Yiqi Droplet 5.0 g three timee a day+conventional therapy after PCI;and Control group,n=50 with conventional therapy after PCI.The concentrations of hs-CRP,PAI-1 and ET-1were detected and compared 24 hours before PCI,and 24 hours,4weeks after PCI between two groups respectively.Results:There were no obvious differences of hs-CRP,PAI-1 and ET-1 24 hours after PCI in two groups.The levels of hs-CRP,PAI-1,ET-1 were lower in Qishen group than in Control group 4 weeks after PCI (0.219±0.143)ng/dl vs.(0.366±0.132)ng/dl,P<0.001,(104.252±26.038)ng/dl vs.(118.419±28.849)ng/ml,P<0.05,and (37.411±12.977)ng/dl vs.(45.755±12.305)pg/ml,P<0.01,respectively.Conclusion:Qishen Yiqi Droplet could decrease the levels of hs-CRP,PAI-1 and ET-1 in ACS patients who underwent PCI,and it might have the protective role in preventing the neointimal hyperplasia and thrombogenesis after stent implantation.
