AMOS-PCR and MLVA were carried out to identify the Brucella strains isolated in Fujian province, which were classified as B. melitensis biovar 2 or 3 by conventional microbiological tests. All these 3 isolates were identified to be B. melitensis by AMOS-PCR. The genetic patterns obtained by MLVA were queried in the Brucella 2007 database and clustered with B. melitensis strains. It is evident that these two molecular assays may be used as the assistant tools in the identification of Brucella strains.

Objective To study efficacy and safety of cilazapril in treating patients with essential hypertension.Method 115 patients with hypertension were divided randomly into two groups:59 were treated with cilazapril and 56 were treated with enalopril.All the patients were washed out for one week,then took 2.5 mg cilazapril or 10 mg enalapril once a day in each group respectively for 8 weeks.If blood pressure was not reduced 2 weeks later,hydrochlorothiazide was added. Result The effective rate of cilazapril and enalapril was 89.8% and 91.1% respectively.The SBP and DBP reduced from 153±15 mmHg and 104±9 mmHg to 131±11 mmHg and 91±8 mmHg respectively in cilazapril group,and from 155±12 mmHg and 102±10 mmHg to 139±14 mmHg and 90±9 mmHg respectively in enalapril group.There were no significant differences in two groups. No side effects were observed in two groups. Conclusion Cilazapril is an effective and safe agent in treatment of mild and moderate essential hypertesion.

Objective To discuss the security and reliability of preoperative thoracoscopic pericardial exploratory and to evaluate of the surgical indications.Methods Video full-assisted thoracoscopic pericardioscopy has been implemented in 41 central type lung cancer cases before radical resection.Results Video assisted pericardioscopy group underwent thoracotomy lung resection with procession of intrapericardial pulmonary artery in 8 cases (partial pericardial resection in 2 cases),with pulmonary vein in 10 cases,and out-pericardial lung resection in 9 cases.Spiral CT projections were consistent with surgery was only 65.8 ％.The average time of explorationa was (23±10) min.Conclusion Except for widely used in pulmonary wedge resection and lobectomy,video-assisted thoracoscopic pericardial exploration can improve resection rate and survival rate in central type lung cancer patients which can reduce the need for exploratory thoracotomy.
