Introduction the standard of diagnosis and treatment guideline[2]. Subjects complicated with severe diseases such as diseases of heart, liver, Bronchial asthma is a common disease of respiratory system. It kidney or hematopoietic system; during pregnancy or breastfeeding is characterized as recurrent paroxysmal asthma, dyspnea, chest period, or with immune stimulant or systematic treatment were distress or cough etc. Recently, the morbidity and mortality of excluded. There were three groups: acute bronchial asthma group, bronchial asthma are increasing. It is reported that the incidence including 27 males and 18 females, aged 37-79 years old, with of adult bronchial asthma is 1.2%-25.5%[1]. At present, imbalance of cytokine excreted by Th1/Th2 cell is regarded as the important average age as (48.2±6.5) years old; bronchial asthma during pathogenesis. Transforming growth factor- 1 (TGF- 1) is a remission period group, including 24 males and 19 females, aged multifunction regulatory cytokine, and plays 毬an important毬 role in 36-80 years old, with average age as (47.5±7.1) years old; and immune regulation, cell growth, cell differentiation, synthesis and control group, including 22 males and 19 females, aged 38-82 years preservation of extracellular matrix. Urotensin- (U- ) can shrink old, with average age as (49.3±7.5) years old. And there was no respiratory tract and pulmonary vessels, and promote栻 栻 proliferation significant difference in age or gender (P>0.05). All subjects signed of smooth muscle in airway and pulmonary artery. So far, no study the informed consent. on correlation between TGF- 1 and U- has been reported. We measured TGF- 1 and U- 毬 by ELISA栻 and radioimmunoassay, respectively to explore毬 the correlation栻 between them. 2.2. Treatment method ELISA for TGF- 1 and radioimmunoassay for U- were 2.

The correlation was analyzed by Pearson of control group (P<0.01), and the level was significantly higher in analysis.
