Pulmonary artery sling(PAS)is a rare congenital cardiovascular disease.Due to the compression of the trachea and esophagus,it often causes severe airway and/or esophageal compression symptoms.Once diagnosed,the patient should undergo surgical treatment.There are various treatments,including left pulmonary artery reconstruction,tracheal stenosis correction and tracheal balloon dilatation and stent technology.Whether or not to repair the tracheal stenosis usually based on the trachea diameter.But there has no ideal surgical procedure to the tracheal stenosis.The patient with complex introcardiac malformation and PAS should be corrected simultaneously with cardiopulrmonary bypass.

Objective:To compare the clinical efficacy of percutaneous radiofrequency ablation (RFA) under ultrasound guidance and high power microwave ablation (MWA) in the treatment of intermediated or advanced-staged primary liver cancer.Methods: 60 patients with primary liver cancer who were in accordance with the inclusion criteria were divided into radiofrequency ablation group (RFA group, 30 cases) and microwave ablation group (MWA group, 30 cases). A series indicators, such as postoperative complete remission rate of lesion, 1 year survival rate, 1 year progression-free survival rate, postoperative adverse reaction and postoperative complication, for these patients of two groups were compared and analyzed.Results:The total complete remission rate of the RAF group and the MWA group were 66.7% and 76.7%, respectively, and the difference between them was significant (x2=3.776, P<0.05). When the lesion was larger than 5 cm, the complete remission rate of RFA group and MWA group were 41.7% and 63.6%, respectively, and the difference between them was significant (x2=4.231,P<0.05). When the lesion was between in 3-5 cm, the complete remission rate of RFA group and MWA group were 75.0% and 81.2%, respectively, while the difference between them was no significant (x2=0.976,P>0.05). For postoperative complication, there were 3 cases in RAF group while there were 5 cases in MWA group, and the difference between them was significant (x2=3.373, P<0.05). There was no death case that was related with treatment in the two postoperative groups. The 1 year survival rate and 1 year progression-free survival rate of RAF group were 90.0% and 53.3%, respectively, and that of MWA group were 86.7% and 60.0%, and the difference between them was no significant (x2=0.877,P>0.05).Conclusion: For intermediated or advanced-staged primary liver cancer with the larger or multiple lesions, complete remission rate of high-power MWA group is better than that of RAF. But there was no significant difference for 1 year total survival rate and 1 year progression-free survival rate between the two groups, respectively. And the postoperative adverse reaction of high-power MWA group was higher than that of RAF group.

Objective To evaluate the long-term effect and safety of triple antiplatelet therapy(cilostazol,aspirin and clopidogrel)for the patients with diabetes and acute coronary syndromes(ACS)undergoing percutaneous coronary intervention(PCI).Methods Between December 2004 and February 2006,a randomized,single center trial was conducted in General Hospital of Shenyang Command for comparison of dual and triple antiplatelet therapy after PCI for the patients with ACS.Of 263 diabetic patients enrolled in present study,122 were randomly assigned to standard dual antiplatelet treatment with aspirin and clopidogrel,141 were assigned to triple antiplatelet therapy with aspirin,clopidogrel and cilostazol.Primary endpoint was a composite of cardiac death,non-fatal myocardial infarction(MI),stroke or target vessel revascularization(TVR)at 1 year.Results Baseline clinical and angiographic characteristics were comparable between the two groups.No definite stent thrombosis or MI occurred in either group during the period of follow-up,and no significant difference existed yet in the rates of 1-year cardiac death(4.1% vs 1.5%,P=0.255),stroke(3.3% vs 0.7%,P=0.186)and TVR(12.3% vs 7.8%,P=0.223)between the patients received dual or triple antiplatelet therapy.The rate of primary events was 9.9%(14/141)in triple group,which was significantly lower than that in dual group [18.9%(23/122),P=0.038].Patients receiving hypoglycemic medicine got more benefits from triple antiplatelet treatment.There was no significant difference between the two antiplatelet regimens regarding the risk of hemorrhagic events and premature discontinuation of aspirin or clopidogrel.Conclusion The regimen of cilostazol plus aspirin and clopidogrel for diabetic patients undergoing PCI is effective and safe in reducing long-term adverse cardiac and cerebral-vascular events,especially for the patients with high dangerous DM complicated with ACS.

To determine the role of biopterin in acute lung injury in scald rats with infection, and to observe the therapeutic effect of GTP-cyclohydrolase I(GTP-CHI) inhibitor on postburn sepsis, 56 male Wistar rats were randomly divided into four groups: normal controls (n=10), scald control group(n=10), postburn sepsis group(n=20) and 2,4-diamino-6-hydroxy-pyrimidine (DAHP) treatment group (n=16). Tissue samples from lungs were collected to determine GTP-CHI and inducible nitric oxide synthase (iNOS) mRNA expression, meanwhile biopterin, nitric oxide (NO), tumor necrosis factor-?(TNF-?) and interferon-? (IFN-?) levels in lungs were also measured. The results showed that after scald injury followed by Staphylococcus aureus challenge, GTP-CHI gene expression and biopterin levels significantly elevated in lungs, so did the values of iNOS mRNA expression and NO induction (P
