ABSTRACT
Non-tuberculous mycobacteria (NTM) are environmental pathogenic bacteria associated with a series of infections. NTM infection can cause pathological changes of related tissues and organs, namely NTM disease. With the further improvement of examination methods, there is more profound understanding of NTM disease, and its epidemiological significance. This article summarizes the research progress on the cell structure, physiological characteristics, pathogenicity, distribution characteristics of NTM; and the morbidity and prevalence, transmission routes and risk factors of NTM disease, to provide information for effective control and treatment of NTM infections.
ABSTRACT
Objective:To observe the efficacy and safety of intrapleural injection with urokinase ( UK) in the treatment of tubercu-lous pyothorax. Methods:Totally 120 patients with tuberculous pyothorax were randomly divided into two groups. The vomicae in the control group were rinsed with 5% sodium bicarbonate, and those in the observation group were treated with UK. The total effective rate, symptom relief time, closure time of vomicae, pleural thickness changes and adverse reactions were observed in the two groups. Results:The total effective rate of the control group and the observation group respectively was 81. 7% and 98. 3%, which showed sta-tistically significant difference (P<0. 01). The symptom remission time and the pus cavity closure time of the observation group were shorter than those of the control group (P<0. 05). The pleural thickness of the observation group was thinner than that of the control group at the end of the treatment (P<0. 05). The incidence of adverse drug reactions in the observation group was significantly higher than that in the control group (P<0. 01). Conclusion:The curative effect of UK in the treatment of tuberculous pyothorax is better than that of sodium bicarbonate, however, it is necessary to pay attention to monitoring such adverse reactions as bleeding, low heat and the others.
