Objective To explore the surgical methods and clinical applications of single operation hole for thorascopic surgery in treatment of encapsulated effusion with atelectasis after thoracic injury.Methods From October 2011 to October 2013,using single operation hole for thorascopic surgery treating encapsulated effusion with atelectasis in 56 cases after thoracic injury,35 males and 21 females,aged 21-68,mean 34 years old.The left encapsulated effusion with atelectasis in 31 cases,the right of encapsulated effusion with atelectasis in 25 cases,atelectasis in 43 cases,partial atelectasis in 9 cases,total atelectasis in 4 cases.Before thorascopic surgery,routine thoracentesis or (and) closed thoracic drainage were performed,but ineffective.Surgical approach for anesthesia with the thorascopic surgery encapsulated effusion dissection + suction drum lung surgery.Thorascopic surgery were completed in single operation hole,postoperative chest tube into the hole from observation.Results The operation time was 55-120 min,average 75 min; blood loss was 25-150 ml,average 65 ml.All patients underwent in single operation hole.The postoperative hospital stay was 7-19 d,average 11.2 d.There were no perioperative mortality and major complications.Conclusions The single operation hole for thorascopic surgery in treatment of encapsulated effusion with atelectasis after thoracic injury is exactly effective and simple.It can be used as an effective treatment.

Objective To compare the effect of the oxytocin, dinoprostone suppositoriesository and cervical dilation balloon in odinopoeia of late pregnancy.Methods A total of 90 patients with late pregnancy singletons primipara were randomly divided into 3 groups with 30 cases in each group. Patients in the group A were treated by dinoprostone suppositoriesository, patients in the group B were treated by oxytocin, patients in the group C were treated by the cervical dilation balloon, the cervical, childbirth, complications and newborns in the 3 groups were observed and compared. Results Compared with group B and group C, late pregnancy induced labor curative effect in group A was better:cervical Bishop score was higher after intervention 6h and 12 h (P<0.05), and promote cervical mature rate and success rate of induced labor were higher(P<0.05), labor time was shorter (P<0.05).The incidence of delivery complications was lower(P<0.05).Conclusion Dinoprostone suppositories can reduce labor time significantly in the treatment of late pregnancy, and improve the success rate of induced labor, the effect is superior to oxytocin and cervical dilation balloon.

Objective To investigate the efficacy and safety of different strategy of antithrombotic therapy in elderly patients with atrial fibrillation (AF) and coronary disease.Methods 224 inpatients and outpatients with AF and coronary disease whose mean follow-up time was 2 years,were divided into warfarin group,warfarin combined with antiplatelet drug(aspirin or clopidogrel) group,antiplatelet drug(aspirin or clopidogrel) group and control group.The thromboembolic event rate and adverse events incidence were observed in different groups.Results The risk of thromboembolic events,particular emerging risk of cerebral infarction in the control group(12.50 ％) was significantly higher than other groups (P＜ 0.05).Thrombotic event rates in warfarin + single joint group(2.78％) was lower than other groups(warfarin group 4.29 ％,single joint group 5.81％),but there was no significant statistical difference.The overall risk of bleeding in the control group (3.13 ％) was significantly lower than other antithrombotic group (P＜0.05).The incidence of skin bruising in single joint group was lower than other antithrombotic groups,the overall bleeding risk,especially gasfrointestinal bleeding in warfarin+ single joint group was significantly higher than other groups (P＜ 0.05).Conclusion Elderly patients with coronary heart disease and atrial fibrillation need antithrombotic therapy to prevent thrombotic events.Using warfarin alone or warfarin combined antiplatelet drug does not lead to serious bleeding events,but generally bleeding risk should be attracted more attention.

Objective To investigate the allelic polymorphism of Human Leukocyte Antigen(HLA)-DRB1*04 in Southern and Northern Chinese Han populations.Method A total of 104 and 168 samples of HLA-DRB1*04 alleles from Southern and Northern Chinese Han populations respectively were genotyped at high-resolution by PCR-SBT,and then the DRB1*0406/0449 ambiguous allele pairs were identified via high-resolution PCR-SSP.The allelic distribution of DRB1*04 in Southern and Northern Chinese Han populations were compared with other different populations by chi-square test.Results All 56 ambiguous allelic pairs of DRB1*0406/0449 were identified as DRB1*0406.A total of 5 alleles were observed in Southern Chinese Han population and the most frequent alleles were DRB1*0405(47.32%),DRB1*0406(24.24%)and DRB1*0403(16.35%).There were 10 alleles tested in Northern Chinese Han population,and the major alleles were DRB1*0405(40.48%),DRB1*0406(18.45%) and DRB1*0403(17.26%).The overall distribution of DRB1*04 alleles in Southern and Northern Chinese Han differed significantly from that of the Caucasian,African American,Hispanics,and Asian and Pacific Islanders,but not from the Korean.Conclusions The overall distribution of HLA-DRB1*04 alleles differed significantly between Southern and Northern Chinese Han populations,but the major alleles DRB1*0405,DRB1*0406 and DRB1*0403 showed the same distribute characteristic.The distribution of DRB1*04 alleles in different populations has their own characteristics.
