ABSTRACT
Objective To evaluate the diagnostic value of endobronchial ultrasound-guided transbronchial needle biopsy (EBUS-TBNA) in intrathoracic tuberculosis(TB).Methods We retrospectively analyzed patients underwent EBUS-TBNA with a final diagnosis of intrathoracic TB at Shanghai Chest Hospital from October 2009 to March 2013 and observed that the diagnostic efficacy by pathology and microbiology and safety of EBUS-TBNA for intrathoracic TB.Results 75 patients were diagnosed with pulmonary TB or intrathoracic tuberculous lymphadenitis,and accuracy was 80％ (60/75) by EBUS TBNA.A total of 60 patients had pathology,acid-fast bacilli(AFB) staining and mycobacterial culture test results,of whom 52 (86.67％)were diagnosed.Pathological findings were consistent with TB in 77.33％ patients (58/75),in 20.31％ (13/64) the smear were positive for AFB and in 46.67％ (28/60) were positive for cuhure.One hundred and twenty-nine mediastinal or hilar lymph nodes and 10 intrapulmonary lesions were biopsied in 75 patients,the average target number of per patient were 1.85.Pathological findings were consistent with TB in 66.19％ samples(92/139),in 13.91％ (16/115) were positive for AFB and in 38.32％ (41/107) were positive for culture.Multivariate regression revealed that short-axis diameter was an independent risk factor associated with positive pathology,smear and euhure.Additionally,more aspiration times cause higher pathology positive rate,pathology showing necrosis and positive smear were independent risk factors associated with positive cuhure.There were two patients occurred complications during operation.Conclusion EBUS-TBNA was a safe and effective method for the diagnosis of intrathoracic tuberculosis.
ABSTRACT
Objective To investigate the regulatory effects of stachyose through oral administration on the facilitating feces excretion function and its relationship to the intestinal flora in stomach irritation with cool water-induced functional bowel disorder rats. Methodes Stomach irritation with cool water -induced constipation-predominant irritable bowel syndrome model rats were administrated by i.g. with stachyose at intestine were determined within 12 hours on the 7th and 14th day after stachyose administration, and intestine flora was measured on the 14th day after Stachyose administration. Results The feces granules and the moisture contests of feces and the efficiency of the small intestine were increased in stachyose treated C-IBS rats, and the number of intestinal flora was significantly higher than that in the control C-IBS rats [ (38.43±4.57) grain VS (32. 21 ± 3.43) grain, F = 3.892, P ＜ 0.05; (47. 88 ± 3.43)% VS (43. 18 ±6.85)%, F =6.724, P ＜0.01;(1.04±0. 11)radian VS (0. 88 ±0.08)radian, F =4.965, P ＜0.05;(10.77 ±0.44)1g(CFU/g) VS (9.85 ±0.43)1g(CFU/g), F =7.613, P ＜0.01;(10.96±0.35)lg(CFU/g) VS (9. 84 ±0. 35)1g(CFU/g), F = 10. 413, P ＜0. 01 ]. Conclusion The results indicated that the stachyose,an extract of Chinese herbal medicine, had the facilitating feces excretion function and modulation functionon intestinal flora in stomach irritation with cool water-induced functional bowel disorder rats.
