Objective: To compare the effects of pericardium patch aortoplasty and pulmonary patch aortoplasty for treating the infants with aorticcoarctation (AC) combining hypoplastic aortic arch in order to provide a better surgical choice in clinical practice.
Methods: A total of 57 patients with AC combining hypoplastic aortic arch treated in our hospital from 2009-01 to 2014-12 were retrospectively studied. The patients were divided into 2 groups: Pericardium patch aortoplasty group,n=26 and Pulmonary patch aortoplasty group,n=31. The changes of the pressure gradient at post-operation and follow-up period were compared.
Results: There were 2/57 (3.5%) patients died, 1 in Pericardium patch aortoplasty group by pulmonary hypertension crisis, the other 1 in Pulmonary patch aortoplasty group by respiratory distress syndrome. No renal failure or neurological complication occurred in neither groups. The cardiopulmonary bypass time, aortic clamping time, ventilator time and ICU stay time were similar between 2 groups,P>0.05. Selective cerebral perfusion time in Pericardium patch aortoplasty group was shorter than Pulmonary patch aortoplasty group (30.5 ± 8.6) s vs (35.6 ± 10.3) s,P<0.05. By ultrasound estimation, the post-operative AC pressure gradients were decreased than they were before, as in Pericardium patch aortoplasty group (9.5 ± 7.5) mmHg vs (39.9 ± 15.5) mmHg and in Pulmonary patch aortoplasty group (11.8 ± 11.3) mmHgvs (39.2 ± 14.5) mmHg, bothP<0.05; while post-operative pressure gradients were similar between 2 groups,P>0.05. Follow-up study was conducted in 51 patients for (17.6 ± 16.6) months, Pericardium patch aortoplasty group had 6 patients with re-stenosis, 3 of them would receive balloon angioplasty and 3 would be continuously followed-up; Pulmonary patch aortoplasty group had 6 patients with re-stenosis, 2 of them ifnished balloon angioplasty and their pressure gradients were obviously decreased, 4 would be continuously followed-up. Kaplan-Meier curves presented that Pulmonary patch aortoplasty group was superior to Pericardium patch aortoplasty group in re-stenosis occurrence during follow-up period.
Conclusion: Both pericardium patch aortoplasty and pulmonary patch aortoplasty were effective for treating the patients with AC combining hypoplastic aortic arch, the early post-operative efifcacy was similar, while the mid-term follow-up result was better in pulmonary patch aortoplasty.

Objective: To summarize the early- and med-term outcomes of modified Fontan operation in patients with functional single ventricle and separate hepatic venous (SHV) drainage. Methods: A total of 39 patients with functional single ventricle and SHV drainage received modified Fontan operation in our hospital from 2009-01 to 2015-12 were retrospectively analyzed. There were 26 (66.7%) male, the average age was (6.98±3.62) years, body weight was (20.79±9.66) kg and pre-operative mean pulmonary artery pressure was (9.77±2.51) mmHg. Based on if SHV combining Apicocaval Juxtaposition (ACJ), the patients were divided into 2 groups: SHV group,n=29 and SHV+CAJ group,n=10. The early (3 months) - and med (5 years)-term post-operative outcomes were analyzed. Results: General clinical data was similar between 2 groups,P>0.05. There were 20/39 patients with one-stage operation, 19 with two-stage operation (18 after Glenn operation and 1 after B-T operation). Modified Fontan operation method was mainly used extracardiac conduit-common open technique (30 patients, 76.9%). 19 patients had CPB with aorta clamping, CPB time was 72-446 (189.74±84.96) min and aorta clamping time was 26-171 (89.05±43.96) min; the other 19 patients had CPB without aorta clamping, CPB time was 60-209 (109.99±98.86) min. 10 patients received re-surgery due to early post-operative complications. 3 patients died at early post-operation with the mortality at 7.7%. The average follow-up time was 3.9 (0.83-7.17) years, 1 patient had cardiac function at NYHA II and the others at NYHA I; the 5-year survival rate was 100%. Conclusion: The early- and med-term outcomes of modified Fontan operation were good in patients with functional single ventricle and SHV drainage. Selection of modified Fontan operation method should be based on the distance form inferior vena cava to SHV and presence of ACJ.

AIM: To establish rat chronic obstructive pulmonary disease(COPD) models by passive cigarette smoking plus intratracheal instillation of lipopolysacchride(LPS) or passive cigarette smoking only, which would be similar to the pathogenesis of human COPD. METHODS: 48 Wistar rats were randomly divided into 4 groups.(1) Healthy control I group( n =12), rats were bred 4 weeks;healthy control II group( n =12), rats were bred for 3 months. (2) Model group I ( n =12), 200 ?g lipopolysaccharide(LPS) was instilled intratracheally once for every two weeks and the rats were exposured to 5% of cigarette smoke, 0.5 h/d for 4 weeks.(3) Model group II(n=12),rats were exposed to 5% of cigarette smoke, 0.5 h/d for 3 months. The pathologic changes of airways and lung tissues, pulmonary function and blood gas analysis were determined. The airway wall lymphocytes and alveolar macrophages were counted. The cross areas of epithelial layer, smooth muscle layer and lamina propria of bronchi were measured. The hydroxyproline of lung tissue homogenates was determined by biochemistry method. RESULTS: The pathologic changes of airways and lung tissue of two models were similar to but milder than those of COPD patients(biopsy data). The collagen deposition and the cross areas of epithelial layer and smooth muscle layer in airway walls of two model groups were significantly increased than those of control groups( P

Objective To investigate whether porcine endothelial cells transfected with SP1 de-coy ODNs could resist complement-mediated cytotoxicity during the model of SV-40-PED with human serum in vitro. Methods Immortalized porcine aortic endothelial cells of the line PED were divided in-to three groups. The transfected group was SV-40-PED with SP1 decoy ODNs. The mismatched group was SV-40-PED with scrambled SP1 decoy ODNs. The negative group was cells with oligo-fectamine only. The expression of α1,3-GT mRNA and αGal was detected after 26 h by using fluores-cence microscope, Western blot, RT-PCR and lactate dehydrogenase (LDH) activity assay. Results Fluorescence microscopy observed the decreased fluorescence of αGal after SP1 decoy ODNs transfec-tion. Dotted fluorescent decrease could be observed on some membrane while the mismatched group and negative group with bright green fluorescence. Western blot showed that the average absorbance of the PED cells transfected with decoy ODNs was decreased to 52.6% of the negative group (P<0.05). The expression of α1,3-GT mRNA in the PED cells transfected with decoy ODNs was 0.42±0.20 (isoform 1) and 0.27±0.12 (isoform 2) respectively, significantly lower than in the negative group (isoform 1, 0.72±0.17; isoform 2, 0.50±0.19; both P<0.05). The expression of α1, 3-G Tin the mismatch group was not different from that in the negative group (P>0.05). 20% normal hu-man serum (NHS) and 40 % NHS had cytotoxic effect on both mismatch and negative groups, but de-coy ODNs could confer SV-40-PED protection from the cytolysis effect (P<0.05), which made a re-markable reduction of complement-mediated cytotoxicity towards SV-40--PED. Conclusions SP1 decoy ODNs could confer porcine endothelial cells protection from complement-mediated cytotoxicity effect in vitro.
