ABSTRACT
Objective To investigate the clinical significance of biochemical markers in EBC and serum in patients with bronchial asthma and chronic obstructive pulmonary disease overlap syndrome(ACOS). Methods We selected Patients with chronic airway inflammatory diseases in our hospital,These patients underwent clinical trial after the stable phase,including 18 ACOS patients,22 asthma patients,24 COPD patients and 20 healthy non-smokers in the same period.8-isoPG and other inflammatory factors levels in EBC and serum were measured in the selected patients. A comparative analysis was performed. Results The levels of EBC 8-isoPG in the ACOS group were significantly higher than those in the healthy control group,The levels of serum and EBC 8-isoPG in the ACOS group were significantly higher than the asthma group and the COPD group(P < 0.05). The level of 8-isoPG in EBC was not related to age,smoking index,weight,and FEV1value(P>0.05).Conclusions Inflam-matory factors including 8-isoPG,are involved in chronic inflammation in lung tissues of patients with ACOS. 8-isoPG in EBC may have potential value in identifying ACOS from COPD and asthma as biomarkers and deserve further study.
ABSTRACT
Objective To investigate the value of ultrasound in typing of epididymal tuberculosis on the clinical treatment . Methods The sonographic characteristics and treatment outcomes were analyzed in 125 patients with epididymal tuberculosis . Results In 125 patients with epididymal tuberculosis ,5 types were divided:( 1 ) Diffusive type ( 37 cases ) presented images of the epididymal diffuse enlargement , abnormal shape ,not smooth surface and inhomogeneous reduced in echogenicity ,13 cases were treated conservatively and 24 cases underwent surgical treatment after failure of conservative treatment . (2) Mass type (24 cases) showed images of hypoechoic mass lesion of caput epididymidis or cauda epididymidis ,4 cases were treated with surgical operation and 20 cases were treat with conservative therapy . (3) Abscess type ( 33 cases) manifested images of irregular liquid anechoic of caput epididymidis and cauda epididymidis , poor ultrasound penetration ,and unclear border . (4) Ulcer‐fistula type (9 cases) revealed images of liquid hypoechoic caput epididymidis or cauda epididymidis extend to the surface of the scrotum . ( 5) Testicular involvement type (22 cases) detected inhomogeneous hypoechoic mass lesion within the testicle and unclear border . The patients of abscess type ,ulcer‐fistula type and testicular involvement type were all treated surgically . Conclusions Ultrasonic diagnosis of epididymal tuberculosis provided a reliable basis for clinical treatment scheme and it was worth recommending .
