ABSTRACT
OBJECTIVE:To investigate the clinical efficacy of alprostadil combined with edaravone in the treatment of unsta-ble angina pectoris(UAP),and their effects on serum oxidative stress indexes,the levels of MMP-2 and MMP-9. METHODS:Be-sides conventional treatment,control group was treated with Alprostadil injection 2 ml added into 0.9% Sodium chloride injection (NS)100 ml,ivgtt,qd;while observation group was additionally treated with Edaravone injection 15 ml added into NS 100 ml, ivgtt,qd. Treatment courses of 2 groups lasted for 2 weeks. The frequency and duration of UAP attack,serum levels of MDA, SOD,TAC,MMP-2 and MMP-9 levels were observed 2 groups;the occurrence of ADR was also observed. RESULTS:There was no statistical significance in frequency of angina pectoris attack,duration,MDA,SOD,TAC,MMP-2 and MMP-9 between 2 groups before treatment (P>0.05). After treatment,the total effective rate of observation group (94.3%) was significantly higher than that of control group(81.4%). The frequency of angina pectoris attack and the level of MDA,were significantly reduced,and the duration of angina pectoris was significantly shortened SOD and TAC increased significantly;the change of observation group was more significant than that of control group with statistical significance(P0.05). CONCLUSIONS:Alprostadil combined with edaravone is significantly effec-tive for UAP,reduces the frequency of angina,shortens the duration of angina pectoris,alleviates oxidative stress and reduces se-rum levels of MMP-2 and MMP-9 with good safety.
ABSTRACT
Objective To study the chest radiographic appearances of the non-tuberculous mycobacterial(NTM) pulmonary infection in patients with acquired immune deficiency syndrome (AIDS).Methods Ten patients with AIDS and NTM underwent chest X-ray radiography and 7 patients performed high-resolution CT (HRCT) scan. Chest radiographic features of NTM in patients with AIDS were retrospectively analyzed. Results The chest radiograph showed bilateral pulmonary involvement in 6 cases and single lung involvement in 4 cases (3 cases in the right, 1 case in the left). Patchy air space consolidation (6 cases), large consolidation (5 cases), cavitation (5 cases), small nodules (3 cases),military nodules (2 cases), linear opacity ( 1 cases) were demonstrated on radiography. On HRCT, air space consolidation (7 cases), small nodules (6 cases), large consolidation (5 cases) with cavitation and cylindric bronchiectasis after the absorption of consolidation, enlarged hilar and mediastinal lymph nodes (4 cases), ground-glass opacities (3 cases), military nodules and "tree-in-bud" sign (2 case), pleural effusion ( 1 case), pericardial effusion ( 1 case) and fibrotic band ( 1 case) were found. Conclusion The most common radiographic appearances of NTM in patients with AIDS are bilateral small nodules, large consolidation with cavitation and cylindric bronchiectasis, enlarged hilar and mediastinal lymph nodes.
ABSTRACT
Objective To manifest the imaging appearances of the pulmonary mucormycesis in patients with acquired immunodeficiency syndrome(AIDS).Methods The radiographic and hiish resolution computed lomography(HRCT)features of the pulmonary mucormycosis in 13 patients with AIDS were retrospectively analyzed.Results On radiography,the infiltrative lesions were found in 5 patients,7 cases had reticular pattem,4 cages had pleural effusion,4 cages had enlarged hilar and mediagtinal lymph nodes,3 cases had diffuse milliary lesions,3 Cages had masses,2 cases had ground-slags shadows,2 cages had cystic lesions,cavity,pleural thickening,pericardia]effusion and focal pneumothorax Wag presented in 1 cage respectively.On HRCT,7 cages had enlarged mediagtinal lymph nedes,7 cages had interlobular septal thickening,the infiltrative lesion were found in 6 patients,5 cages had diffuse milliary lesions,4 cages had pleural effusion,3 cases had inasses,2 cages had ground-glass shadows,2 cases had cystic lesions,cavity,pleural thickening,focal bronchiectagis,pericardial effusion and focal pneumothorax was presented in 1 case respectively.Conclusion The main imaging appearances of the pulmonary mucormycesis in patients with AIDS include diffuse milliary lesion,enlarged hilar and mediagtinal lymph node,interiobular septal thickening,infiltrative lesion,pleural effusion and mass.
ABSTRACT
<p><b>OBJECTIVE</b>To study the chest X-ray image features of patients with severe SARS.</p><p><b>METHODS</b>Chest X-ray image features in 36 patients with severe SARS were retrospectively analyzed. The image characteristics were compared with those of 224 patients with common SARS.</p><p><b>RESULTS</b>The important chest X-ray imaging features of 36 patients with severe SARS included small patch of infiltration (n = 27, 75.0%), large patch of infiltration (n = 22, 61.1%), large area of lung consolidation (n = 10, 27.3%), interstitial lung lesion (n = 26, 72.2%), ground-glass shadow (n = 28, 77.8%), irregular linear opacity (n = 15, 41.7%), diffuse lung lesion (n = 12, 33.3%), with single lung involved (n = 9, 25.0%), and both lungs involved (n = 32, 88.9%). The rates of large patch of infiltration, large area of lung consolidation, ground-glass shadow, diffuse lung lesion and involvement of both lungs in patients with severe SARS were significantly higher than those in patients with common type of SARS (all P < 0.01). Out of the 11 severe SARS patients who died, nine had large area of ground-glass shadow with air bronchogram in both lungs before death.</p><p><b>CONCLUSIONS</b>Large patch of infiltration, large area of consolidation, ground-glass shadow, diffuse lung lesion and involvement of both lungs were the main X-ray image characteristics of patients with severe SARS. Large area of ground-glass shadow with air bronchogram in both lungs indicated a bad prognosis.</p>
