Objective To investigate the clinical effectiveness of coronary artery bypass grafting through descending thoracic aorta in elderly patients with coronary heast disease and to decrease the post-operative complication.Methods Thirteen elderly patients underwent coronary bypass surgery with minimally invasive direct coronary artery bypass (MIDCAB).Age range from 70 to 82 years with a mean of(72.1?6.0)years.Patients suffered from multi vessel disease.Many minimally invasive techniques of“Y”blood vessel graft anastomosis,anastomosis of blood vessel graft to descending aorta,minimally invasive direct,thoracoscope assist were used.Results All patients were survived.The mean duration of intubation was (6.9?0.9) hours.The average ICU stay was (2.5?0.5)days.No patients received blood transfusion.During the short-term follow-up(3 to 14 months) patients had no complaint of angina,Conclusions The technique of“Y”blood vessel graft anastomosis,descending aorta blood vessel graft,minimally invasive direct and thoracoscope assist in combination with coronary artery bypass grafting is a safe and cost-effective new procedure for elderly patients with multi-coronary artery disease.

Objective To explore the relationship between 5, 10-methylenetrahydrofolate reeducates gene polymorphism of the parents and the susceptibility to their offspring having neural tube defects. To forecast and evaluate the onset risk of neural tube defects (NTDs) on the basis of 5, 10-methylenetrahydrofolate reeducates (MTHFR) C677T polymorphism on parents of the patients.Methods Electronic search strategy was carried out among the five databases from home and abroad to collect qualified research papers, according to the inclusion and exclusion criteria. Case-control studies on association between MTHFR polymorphism and susceptibility to NTDs were collected and divided into two groups as mothers and fathers. The combined OR values and their 95% CI were calculated with Review Manager 5.0. Results 33 eligible studies were included. Statistics of the combined data showed a significant difference between the mothers with NTDs offspring carrying TT/CC, CT/CC of MTHFR gene C677T and controls. The pooled OR (95%CI) were 1.68 (1.32-2.14)and 1.20 (1.07-1.35) respectively. These was a significant difference between the fathers of the offspring with NTDs that carrying of TT/CC, CT/CC of MTHFR gene C677T and controls. The pooled ORs (95%CI) were 1.38 (1.08-1.76) and 1.32 (1.13-1.55) respectively. Conclusion The results suggested that the paternal and maternal MTHFR gene C677T polymorphism were risk factors to NTDs.

Objective To identify the different causes of atrial fibrillation (AF) in Chinese by coronary artery angiography,and to compare the episode of stroke in different patients.Method A total of 782 adult patients diagnosed with AF were identified from Anzhen Hospital over a 8-year period.There were 273 patients with rheumatic valvular AF and 509 patients with nonvalvular AF.The results of electrocardiogram,echocardiography and coronary artery angiography were retrospectiwely analyzed to find out the proportion of causes and to compare the episode of stroke in patients with rheumatic valvular AF with those having nonvalvular AF.Results The patients with rheumatic valvular atrial were significantly younger than of coronary heart disease (52.40?5.03 years old vs 64.30?3.25 years old,P

Objective:To investigate the expression of HIF-1?and its relationship with angiogenesis in osteosarcoma.Methods: Osteosarcoma MG-63 cells were cultured in vitro under hypoxia and mimic hypoxia conditions.Thirty paraffin-embedded osteosarcoma tissues and 20 fresh frozen osteosarcoma specimens were collected.The mRNA and protein expression of HIF-1?and VEGF were detected by RT-PCR,Western blotting,ELISA,and immunohistochemistry methods.The mean vessel density(MVD)were also calculated.Results:The mRNA level of HIF-1?had no change under hypoxia and minic hypoxia conditions,whereas the protein expression was increased dramaticaly.The mRNA and protein expression of VEGF was significantly increased under hypoxia and minic hypoxia conditions.The positive rate of HIF-1?mRNA(90%)and VEGF(100%)in 20 fresh frozen tissues were higher than those of the para-tumor tissues(P

Objective To evaluate the feasibility of 3-(4-~(18)F-fluorobenzyl)-8,9-dimethoxy-1,2,3,4-tetrahydrochromeno [3,4-c]pyridin-5-one ( is F-FDTP) as a potential dopamine D4 receptor PET imaging agent.Methods ~(18)F-FDTP solution in ethanol-physiological saline was incubated with calf serum to test its in vitro stability through the determination of radiochemical purity.Normal rats were injected intravenously with ~(18)F-FDTP and then sacrificed at 2,5,10,15,30,60 and 120 min after anesthesia.Blood,organs and brain tissue samples were collected.All samples were weighed and measured for radioactivity.The uptake of samples was expressed as percentage activity of injection dose per gram of tissue ( % ID/g).Results The stability of ~(18)F-FDTP was satisfactory and its radiochemical purity was above 95% after incubation 120 min at 37℃ in calf serum.The biodistribution showed that ~(18)F-FDTP could penetrate through the blood-brain barrier and selectively accumulate in striatum,hypothalamus,frontal certex,hippocampus,cerebellum,where the D_4 receptor was reportedly located.The radioactivities in hippocampus,hypothalamus,striatum,frontal cortex,cerebellum,pons were (0.42±0.03),(0.46±0.05),(0.54±0.04),(0.39±0.04),(0.45±0.06),(0.35±0.04) %ID/g,respectively,2 min post injection.And there was difference between the normal biodistribution results and the blocking experimental results:(0.36 ±0.05),( 0.33±0.05 ),(0.55±0.05 ),(0.30±0.07 ),(0.34±0.07 ) and (0.32±0.04) % ID/g in hippocampus,hypothalamus,striatum,frontal cortex,cerebellum and pons,respectively.Conclusions ~(18)F-FDTP can penetrate through the blood-brain barrier and selectively accumulate in striatum,hypothalamus,frontal cortex,hippocampus,cerebellum,where the D_4 receptor was known to concentrate.These preliminary results suggest that ~(18)F-FDTP is a potential dopamine D_4 receptor imaging agent and further studies are needed.
