Objective To explore the predictive value of heart-type fatty acid-binding protein (HFABP) in predicting the cardiovascular events after none-cardiac thoracic surgery in aged patients.Methods Sixty eight aged patients were admitted from February 2012 to August 2014 and accepted none-cardiac thoracic surgery.The patients'general information and the incidence of postoperational cardiovascular events were recorded.Serum H-FABP was measured.The receiver operating characteristic (ROC) curve was constructed and the predictive effect of serum H-FABP for prognosis was analyzed.Results Eighteen patients were suffered from postoperative cardiovascular events (PCE).The level of H-FABP after surgery in patients with PCE was higher than that with none-PCE (P ＜ 0.05).The serum concentration of H-FABP after surgery and NT-proBNP before surgery was the independent risk factors for the elderly patients undergoing non-cardiac thoracic surgery.The area under ROC of H-FABP was 0.840 (95％ CI:0.716 ～0.964,P ＜0.01).The sensitivity and specificity of predicting postoperational cardiovascular event with serum concentration of H-FABP ＞5.26μg/L was 77.8％ and 84.0％ (OR 15.944,95％ CI:4.239 ～59.978,P ＜0.01).Conclusions The level of H-FABP after surgery is an independent risk factor for the occurrence of PCE for the elderly patients undergoing non-cardiac thoracic surgery.It can predict the risk of PCE after non-cardiac thoracic surgery in aged patients.

Objective To compare the oil yield of celery seeds and the contents of 3-n-butylphthalide and the total phthalocyanine lactones of celery seed oil extracted by different methods. Methods Three routine extraction methods involving organic solvent extraction, Soxhlet extraction, steam distillation extraction, as well as subcritical extraction method and supercritical fluid extraction method were used to extract the celery seed oil. The contents of 3-n-butylphthalide and total phthalocyanine lactones were respectively detected by high performance liquid chromatography(HPLC) and ultraviolet visible spectrophotometry. Results The ranges of oil yield and the contents of 3-n-butylphthalide and total phthalocyanine lactones of celery seed oil extracted by different methods were 0.30%-20.02%, 1.40%-10.13%, 4.74%-17.65%, respectively, indicating obvious differences. Conclusion With R134a and butane as the solvents, the subcritical extraction method is better than other extraction methods for the extraction of 3-n-butylphthalide. With dimethyl ether as the solvent, the subcritical extraction method is the best for the extraction of total phthalocyanine lactones.

Intravenous preparations take more risk than oral preparation and externally applied agent.In phaseⅠtoler- ance trial of intravenous preparations of TCM on human subjects,minimum dose and maximum dose should be decided in light of data derived from preclinical pharmacodynamic and toxicological experiments,combined with practical situation in clinic.Dose-ascending coefficient of the should be reasonable.During the application of intravenous preparations of TCM in tolerance trial,clinical monitoring must be done to ensure the safety of subjects.Overall and integrated observa- tional indices should be designed on the basis of the features of preparation types,administration methods,the nature of medicine,etc.,so as to provide full-scale data for safe dose range,concentration of the preparation,dripping veloci- ty and possible adverse reactions,etc.

Objective To preliminarily investigate the methods,safety and short to medium-term effectiveness of the interventional ultrasound applying in the hybrid procedure to treat the thrombosis of arteriovenous graft(AVG).Methods Twenty patients with the thrombosis of AVG,who received the hybrid procedure defined as Fogarty catheter thrombectomy and percutaneous transluminal angioplasty (PTA) guided by the ultrasonography,were retrospectively investigated. The display effects of the ultrasonography were observed.The technical and clinical success rates were evaluated.All the cases were followed up every 3 months for at least 1 year to evaluate the post-interventional assisted primary patency and the post-interventional secondary patency.Results All the processes were clearly displayed and well guided by the interventional ultrasound during the procedure.The technical and the clinical success rates were both 100%.No major complications were recorded.The post-intervention assisted primary patency rate was 100%,92.9%,85.7%,71 .4% at 3,6,9,12 months,respectively.The post-intervention secondary patency was 100%,100%,89.5%,89.5% at the correspondent months.Conclusions This pilot research shows the hybrid procedure guided by the interventional ultrasound to treat the thrombosis of AVG has high success rate and satisfied patency in short to medium-term.The interventional ultrasound is an effective, safe and convenient guiding method to the hybrid procedure,and has the value for clinical application.

Objective To evaluate the feasibility,efficacy,and short to mid-term results of endovascular management of acute type B aortic dissection complicating visceral or lower limb malperfusion.Methods A retrospective study was conducted in 23 consecutive patients with acute type B dissection complicating visceral or lower limb malperfusion treated endovascularly at a single center between July 2001 to December 2012.Of the 23 patients identified [20 men,3 women; mean age (52 ±9) ranging 42-75]presented with clinical and imaging evidence of end-organ malperfusion:renal artary in 5 (21.7％),superior mesenteric artery in 9 (39.1％),celiac trunk in 3 (13％) and lower limb in 6 (20.1％),artary renal and lower limb in 2.Results All patients had stent-graft coverage of the proximal entry tear.11 (47.8％) patients needed additional branch vessel stenting.Successful correction of malperfusion was achieved in all the patients and the successful rate of operation and technology was 100％.In 1 patient,ischemia in the lower limb was resolved after a stent was implanted to the right iliac artery.In another patient,complicated with lower limb ischemic necrosis,amputation was performed after one stage stent-graft placement.The duration of follow-up was 6 months to 72 months,mean (21 ± 11)months.There was no migration of stent-graft and end-organ ischemia.No patients suffered from paraplegia in this group.Conclusions Endovascular coverage of the proximal entry tear in acute type B aortic dissections complicating end-organ malperfusion is a reasonable first line treatment.But some cases may need a combination branch vessel stenting.
