Objective To evaluate the effectiveness of interventional procedures in the treatment of acute pulmonary embolism(PE). Methods Pulmonary arterial thrombolytic therapy, suction and fragmentation of thromhi, anti-spasm, and balloon dilation were performed in eighteen cases with clinically highly suspected PE confirmed by emergent pulmonary artery angiography beforehand. Wedged pulmonary arterial pressure, pulmonary recanalization rate, the display ratio of distal pulmonary capillary net, blood gas analysis, blood oxygen saturation, and the improvement of clinical symptoms and signs were used for evaluation of the effectiveness. Seventeen of the alive cases with dislodgement of deep vein thrombi of the lower extremities were confirmed for the formation of PE and then thrombolytic treatment of the thrombotic deep vein was performed after the placement of inferior vena cava filter. Results Pulmanory artery angiographies showed embolism of the pulmonary arterial trunks or more than two of the branches. The post-treatment pulmonary patency reached 80%-90% in three cases, 90%-95% in eleven cases and 100% in five cases. The display ratio of distal pulmonary capillary net was over 90% in all the cases. Wedged pulmonary arterial pressure decreased to below 25 mmHg in thirteen cases, and to 25-30 mmHg in five cases. Blood oxygen saturation rate improved immediately to 90%-95% in ten cases and to 95%-100% in eight cases. Cough, hemoptysis, dyspnea, and chest pain were completely relieved in thirteen cases and significantly relieved in five cases. Digestive track bleeding was complicated in one case. Conclusions Pulmonary artery angiography is the golden standard for the diagnosis of pulmonary embolism. Interventional therapy is very effective for acute pulmonary embolism, which can significantly reduce the mortality rate.

Chinese Traditional and Herbal Drugs 2013;44(9):1162-1167
Objective: To study the mechanisms of absorption and transport of 3-acetyl-11-keto-β-boswellic acid (AKBA) from Boswellia carterif in Caco-2 cell, MDCK-MDR1, and MDCK-Wild cell models. Methods: The Caco-2, MDCK-MDR1, and MDCK-Wild cell monolayer models were used to study the bi-directional transport of AKBA in apical (AP)→basal (BL) or BL→AP; The concentration of AKBA was measured by LC-MS/MS and apparent permeability coefficient (Papp) was calculated. Results: Papp (AP→BL) and Papp (BL→AP) values of AKBA (50 μmol/L) in Caco-2 cell model were 7.9 × 10-7 and 1.5 × 10-7 cm/s, respectively; Papp (AP→BL) and Papp (BL→AP) values of AKBA (50 μmol/L) in MDCK-MDR1 cell model were 2.6 × 10-7 and 0.8 × 10-7 cm/s, respectively; Papp (AP→BL) and Papp (BL→AP) of AKBA (50 μmol/L) in MDCK-Wild cell model was 2.4 × 10-7 and 0.6 × 10-7 cm/s, respectively; The rates of efflux (RE) for AKBA in Caco-2 and MDCK-MDR1 cell monolayers were both smaller than 2. Conclusion: AKBA is not the substrate of P-gp and its absorption rate is low. AKBA is absorbed through the intestinal epithelial cells by active transport absorption and passive diffusion possibly.

Objective To investigate the effects of Mycobacterium vaccae vaccine on immunological function and clinical character in elderly patients with stable chronic obstructive pulmonary disease (COPD). MethodsA total of 100 elderly patients with stable COPD were randomly divided into immunotherapy group (group A, n= 50) and non-immunotherapy group (group B, n= 50), and normal control group (group C, n = 50). The levels of peripheral blood T-lymphocyte subsets (CD3+ , CD4+, CD8+ , CD4+/CD8+ ratio), natural killer cells (NK cells), immunoglobulins (IgG, IgA, IgM) and cytokines (IL-6, IL-8, TNF-a) were measured respectively before and after therapy. Group A and B were followed up for 1 year, then the times of acute outbreak and hospitalization of patients in the two groups were also compared. Results The levels of CD4 + ,CD4+/CD8+ ratio and NK cells in group A, B were significantly lower before therapy (P<0. 05~0. 01=, and the levels of IL-6, IL -8, TNF-a and IgA were significantly higher than in group C (P<0. 01=. After treatment with Mycobacterium vaccae vaccine in group A, the levels of CD4+ , CD4+/CD8+ ratio and NK cells were significantly higher (P<0. 05-0. 01= and IL-6, IL-8, TNF-a and IgA were significantly lower than before treatment (all P<0. 01=. These levels showed no significant changes in group B after treatment (P>0. 05). After 1-year follow-up, the times of acute outbreak and hospitalization on patients were statistically lower in group A than in group B (P< 0. 01 ).ConclusionsMycobacterium vaccae vaccine can improve cellular immunity function and reduce the times of acute outbreak and hospitalization in patients with stable COPD, so it has a higher clinical application value.
