Tiotropium in Patients with Bronchiectasis: A Prospective Cohort Study.

Purpose: There are limited studies on the use of bronchodilators for the treatment of bronchiectasis. This study investigated the efficacy of tiotropium in patients with bronchiectasis and airflow limitation.

Methods: This study was a prospective cohort study, including 169 patients with bronchiectasis and airflow limitation from 2015 to 2019.

Long-term results of extended Boari flap technique for management of complete ureteral avulsion: A case report.

Background: Ureteroscopy is well-established as a primary treatment modality for urolithiasis. Ureteral avulsion, particularly complete or full-length avulsion with a resultant long segment of the ureter left attached to the ureteroscope, is a rare but devastating complication of the procedure. Management of this complication is challenging.

Development of a new outcome prediction model for Chinese patients with penile squamous cell carcinoma based on preoperative serum C-reactive protein, body mass index, and standard pathological risk factors: the TNCB score group system.

Purpose: To determine the predictive value and feasibility of the new outcome prediction model for Chinese patients with penile squamous cell carcinoma.

Results: The 3-year disease-specific survival (DSS) survival (DSS) was 92.3% in patients with < 8.

Expression variations of connective tissue growth factor in pulmonary arteries from smokers with and without chronic obstructive pulmonary disease.

Cigarette smoking contributes to the development of pulmonary hypertension (PH) complicated with chronic obstructive pulmonary disease (COPD), and the pulmonary vascular remodeling, the structural basis of PH, could be attributed to abnormal proliferation of pulmonary artery smooth muscle cells (PASMCs).In this study, morphometrical analysis showed that the pulmonary vessel wall thickness in smoker group and COPD group was significantly greater than in nonsmokers. In addition, we determined the expression patterns of connective tissue growth factor (CTGF) and cyclin D1 in PASMCs harvested from smokers with normal lung function or mild to moderate COPD, finding that the expression levels of CTGF and cyclin D1 were significantly increased in smoker group and COPD group.

Expression of IL-17A and IL-17F in lipopolysaccharide-induced acute lung injury and the counteraction of anisodamine or methylprednisolone.

Th17 cytokines IL-17A and IL-17F as pro-inflammatory cytokines played an important role in triggering inflammatory responses. However, little was known about the expression of IL-17A and IL-17F in acute lung injury (ALI). Therefore, the present study investigated the expression of IL-17A and IL-17F in lipopolysaccharide (LPS)-induced ALI in rats and rat pulmonary microvascular endothelial cells (PMVEC) by enzyme-linked immunosorbant assay or reverse transcription-polymerase chains reaction.

[Prognostic significance of the 2004 WHO classification compared with the 1973 WHO classification for organ-confined invasive bladder cancer].

Objective: To compare the 2004 and 1973 WHO classifications for predicting tumor recurrence for organ-confined (T stage ≤ pT2b) invasive urothelial carcinoma of the bladder treated with radical cystectomy.

Methods: From February 2000 to August 2011, the 173 consecutive cases of organ-confined invasive urothelial carcinoma of the bladder were treated with radical cystectomy. The data of clinical and follow-up information was collected.

Age-specific effect of gender on upper tract urothelial carcinoma outcomes.

The research is to evaluate the age-specific differential effects of gender on outcomes in patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). Between August 1998 and October 2010, we retrospectively reviewed the data from 285 (67.7%) men and 136 (32.

Practical value of intravenous urography combined with add-on CT in diagnosing ureteral abnormalities.

Background: Intravenous urography (IVU) combined with add-on CT (IVU-CT) can help to provide more diagnostic information for determining the localization and nature of ureteral abnormalities with less irradiation dose. This study aimed to determine the value of IVU-CT for diagnosis of ureteral diseases, where IVU is insufficient to determine the diagnosis.

Methods: Two hundred and eighty patients underwent IVU for suspected ureteral disorders, which identified a definite diagnosis in 184 cases and was insufficient for definite diagnosis in 96 cases designated as indeterminate diagnosis.
