RESUMEN
Pulmonary embolism is a clinical and pathophysiological syndrome caused by endogenous or exogenous emboli obstructing the pulmonary artery , and its branches causing acute pulmonary circulatory disturbances .Venous thromboembolism is a complex multifactorial disease that involves the interaction of secondary or hereditary thrombosis and various risk factors such as trauma and surgery .With the characteristics of high incidence , misdiagnosis and high mortality ,this study explored the risk factors for pulmonary thromboembolism .Finding its risk factors is the main method to reduce the incidence of pulmonary embolism and reduce the severity of pulmonary embolism.
RESUMEN
Tuberculous pleurisy is the common disease in pleural disease ,this disease had different degree of lung injury.In recent years,lung function rehabilitation training is a hot spot .This article will elaborate breathing training application and its value in tuberculous pleuritis .
RESUMEN
Objective To compare the concentrations of alpha-enolase (ENO1),CYFRA21-1,and CA125 in the patients with malignant pleural effusion ,tuberculous exudative pleural effusion ,or parapneumonia pleural effusion. To explore the clinical value of ENO1 in pleural effusion combined with serum CYFRA21-1 and CA125 in diagnosis of malignant pleural effusion. Methods Enzyme-linked immunosorbent assay(ELISA)was used to detect the concentration of ENO1 in pleural effusions. The concentrations of CA125 and CYFRA21-1 in the blood samples were measured using chemiluminescence and magnetic particle-based chemiluminescence respective-ly. The sensitivity and specificity of ENO1 combined with serum CYFRA21-1 and CA125 detection were calculated. Results The concentration of ENO1 in malignant pleural effusion group was significantly increased(P<0.001);the concentrations of ENO1 did not differ significantly between tuberculous exudative pleural effusion and parapneu-monia pleural effusion(P>0.05). The sensitivity and specificity of ENO1 combined with serum CYFRA21-1 and CA125 detection in malignant pleural effusion were 94％ and 74％,98％ and 98％,respectively. Conclusions ENO1 combined with serum CYFRA21-1 and CA125 detection can improve the sensitivity of diagnosis of malignant pleural effusion and enhance the diagnostic rate of malignant pleural effusion.

RESUMEN
Objective To observe the efficacy of inhaled tiotropium bromide combined with budesonide/formoterol on reducing the frequency of acute episodes of symptom exacerbation and improving lung function,health status in chronic obstructive pulmonary disease (COPD). Methods Eighty-six patients with COPD were divided into 3 groups, combination group[29 cases, inhaled budesonide/formoterol (160 μg/4.5 μg, twice one day ) and tiotropium bromide ( 18 μg, once one day)], budesonide/formoterol group( 29 cases, 160 μg/4.5 μg, twice one day) and tiotropium bromide group(28 cases, 18 μg, once one day). The treatment continued for 3 months. Results Lung function, symptoms and health status improved obviously in three groups. The forced expiratory volume in one second (FEV1) of combination group after treatment was (1.24±0.18) L , which was improved by 11.7% compared with before treatment. It was significantly higher than that in budesenide/formoterol group and fiotropium bromide group (P < 0.01 ). The rescue medication consumptions and the times of acute episode of combination group were significantly decreased compared with those in the other groups,and there was significant difference (P <0.01). The SGRQ score of combination group was (35.6±13.9) points which was significantly lower than that of budesonide/formoterol group and tiotropium bromide group,and there was significant difference (P < 0.01 ).There was no statistical difference in the adverse events occurred in three groups (P > 0.05 ). Conclusions Combination treatment produces better control of symptoms and lung function and has no greater risk of sideeffects, compared with the treatment of budesonide/formoterol alone and tiotropium bromide alone. The combination treatment should be considered for patients with COPD.
RESUMEN
Objective To investigate the correlation between the mierosatellite polymorphism of heme oxygenase-1(HOX-1)gene promoter and susceptibility to chronic obstructive pulmonary disease(COPD)in Han nationality of Southwest China and CT imaging.Method The alleles frequencies with varying number of(GT)n repeatings in the Hox-1 gene in 180 smokers with COPD and in 150 healthy smokers were analyzed.Results Polymorphisms of the(GT)n repeats were grouped into three classes:S(≤25 repeats),M(26-31 repeats),L(≥32repeats).The proportion of genotypic frequencies in the group with class L alleles(L/S,L/M,I/L)was significantly higher in the smokers with COPD than in healthy smokers(29.4%vs18.7%,P=0.023,OR=1.8,95%CI 1.1-3.1).However,there was no relationship between the polymorphism of HOX-1 gene and subtypes of COPD by CT imaging in COPD patients(P＞0.05).Conclusion Genetic polymorphism in Hox-1 is associated with development of COPD in Han nationality of Southwest China.But the polymorphism of HOX-1 gene is not associated with subtypes of COPD by CT imaging.
RESUMEN
Objective To investigate the correlation between GSTP1 exon5 A/G polymorphism and clinic phenotype of COPD in the population of the Han nationality from southwest China.Methods Using PCR followed by restriction fragment length polymorphism(PCR-RFLP),genotypes of Ile105Val polymorphism in exon5 of GSTP1 were determined in 91 patients with COPD and 87 healthy control subjects.Results No significant differences were observed in the frequencies of genotypes and alleles of exon5 of GSTP1 between COPD patients and the healthy controls.The frequency of Ile105 in pink puffer patients was much more than that in the blue bloater patients.The CT scores of emphysema in patients with Ile105 was significantly higher than those with Val105.Conclusions The genetic polymorphism of exon5 of GSTP1 may not be associated with the susceptivity of COPD in the populations of the Han nationality from southwest China,but may be correlated with clinical phenotypes and lung parenchyma damage of COPD patients in the present population.
