ObjectiveTo determine whether simvastatin alleviates lower urinary tract symptoms (LUTS) in patients with metabolic syndrome (MS) coexisting with benign prostate hyperplasia (BPH) and explore an optimized scheme of treatment. MethodsFrom February to June in 2011,30 male subjects with MS and LUTS caused by BPH in out-patients and in-patients from geriatric department were recruited.The patients were randomly assigned to receive orally simvastatin (40 mg) and tamsulosin (0.2 mg) quaque noete as combination treatment group or only tamsulosin (0.2 mg,quaque nocte) as single treatment group for 8 weeks.International prostate symptoms score (IPSS),quality of life (QOL),maximum flow rate (MFR) and prostate volume (PV),liver enzymes,creatinine and routine urine test were monitored to evaluate the effectiveness and safety before and after the treatment.Results In the two groups,the significant differences were found in the levels of IPSS,QOL and MFR,while there was no difference in PV between pre-treatment and post-treatment.The scores of IPSS after treatment were (6.4 ± 4.4) in combination treatment group and(4.2±3.3)in single treatment group (P＜0.05),and there were significant difference in scores of IPSS before and after the treatment between two groups (P＜0.05),suggesting better improvement in combination treatment group than in single treatment group.In two groups,there were no adverse events,and no changes were found in liver and kidney function,muscle enzymes and routine urine test.Conclusions Combined tamsulosin and simvastatin treatment may alleviate LUTS caused by BPH and are well tolerated with no adverse events.

Objective To investigate the morbidity of anomalous coronary origin from the opposite coronary sinus, which may cause sudden death of young athletes in Chinese population.And to identify the imaging characteristics of this anomaly and its clinical significance combined with literature review.Methods The computed tomographic coronary angiography (CTCA) database at TEDA International Cardiovascular Hospital was reviewed.All of the patients diagnosed with isolated anomalous origin of a coronary artery from the opposite sinus of valsalva (anomalous origin of coronary artery, AOCA) and subsequent coursing between the pulmonary artery and the aorta were collected from 14 343 Chinese individuals.The location of anomalous coronary origin, the shape and course of the proximal ectopic arterial segments were identified.The nonatherosclerostic stenotic caliber of the segments and the angle between the ectopic coronary artery and the adjacent aortic wall were assessed.Results Seventy-four patients of AOCA (including the left or right single coronary artery) were diagnosed using CTCA.Among the 74 cases, the potentially serious course of the ectopic coronary artery between the pulmonary artery and the aorta were identified in 59 individuals.Fifty-six cases of ectopic right coronary with interarterial course (anomalous origin of right coronary artery, AORCA) and three patients with anomalous origin of the left coronary artery (AOLCA) were found, including two cases judged as potentially serious origin of either single left coronary artery (n=1) or single right coronary artery (n=1).The morbidity of the potentially serious anomalous origin of coronary artery in Chinese population was established as 4.1‰ (59/14 343).In the subgroup of AORCA, the lumen of initial ectopic segment was frequently compressed and stenotic.In 29 cases (52.7%) the stenosis of the lumen were more than 50%, and in 3 cases (5.4%) the stenosis of the ectopic coronary artery were more than 70%.The incidence of AORCA was 17.7 times higher (56/3) than that of AOLCA in Chinese population.Conclusions Nowadays CTCA is considered the most useful imaging technique in identifying the origin, shape and course of ectopic initial segment of the coronary artery.The significance of these anatomic characteristics, that may induce sudden death in Chinese young athletes, need to be investigated further.

Objective To discuss the preliminary experience of transcatheter aortic valve implatantion in patients with severe aortic valve stenosis. Methods The baseline characteristics, hemodynamic changes and clinical outcomes of the patients received TAVI in our institution were analyzed. Results A total of 36 patients underwent TAVI between April 2012 and March 2014. The mean age was (73.4±8.7) years and 24 (66.7%) of them were men. The mean logistic EuroSCORE was (20.6±9.9)%. 25(70%) patients had bicuspid aortic valves. TAVI was successful in 35 patients (97.2%) and valve-in-valve implantation was required in 4 (11.1%) of them. After the procedure, the mean aortic-valve gradient reduced to (10.5±5.7) mmHg. In 2 patients (5.6%), there was marginal moderate periprosthetic leak. At 30 days, the survival rate was 97.2%. Two patients (5.6%) developed who later showed fuel recovery, without significant sequela. Permanent pacemakers were implanted in 10 patients (27.8%) due to the onset of third-degree atrioventricular block after TAVI. To date, the median follow-up duration has exceeded 323 days. 2 patients died of cancer on 374 days and 680 days after TAVI, respectively. Conclusions TAVI is feasible, safe and effective in treating severe stenosis of bicuspid as well as tricuspid aortic valve in selected Chinese patients unsuitable for surgery.

Objective To explore the serum levels of progestrone (Prog) and dehydroepiandrosterone sulfate(DHEAS),and the effect of sodium valproate(VPA) and lamotrigine(LTG) on the levels of Prog and DHEAS in infantile spasms.Methods A total of 36 cases of infantile spasms (spasms group) before treatment and 40 cases health infants(control group) were detected the serum Prog and DHEAS levels by electrochemiluminescence immunoassay,and were compared with 21 cases receiving monotherapy with VPA(VPA group),and 13 cases receiving therapy plus lamotrigine(LTG group) before and 4 months after treatment to observe the changes of sex hormone.Results There were no significant differences in Prog and log(DHEAS) (logarithmic transformation) levels between spasms group and control group (P ＞0.05).The serum Prog level of baby girls and baby boys were lower after treatment than those before treatment in VPA group respectively (t =2.603,3.146 ; P =0.003,0.008,respectively).The log (DHEAS) level of baby girls and baby boys were higher in LTG group after treatment than those before treatment respectively(t =3.185,2.663 ;P =0.007,0.041).Conclusion Infantile spasms would not influence the hormone metabolism,while VPA and LTG can influence the sex hormone.The hormone level should be monitored in the treatment.

With the heavier burden of cardiovascular disease, an abundance of papers emerge every year in the research hotspots, which cover a wide range of types and content. In order to let readers interested in the cardiovascular field quickly understand the research hotspots and research frontier, it is necessary to sort out and summarize the research topic in time. According to the discipline classification, we screened papers in cardiovascular field from the Essential Science Indicators (ESI) hot papers published in 2019. Methods such as bibliometrics, statistical description, hierarchical induction, analysis and interpretation were used a step further to reveal the context and characteristics of research in the field of cardiovascular diseases, summarize the latest progress and development direction in this field, and provide information and hints for the expansion of future research directions. A total of 297 papers were finally included, which were mainly in the field of clinical medicine; The country with the most publications was the United States, while China ranked the fifth in terms of contribution; the research institution with the highest number of published papers was Harvard University;
