Introduction: This study was to develop a simple model for predicting malignancy of peripheral pulmonary lesions (PPLs) based on endobronchial ultrasonography (EBUS) and clinical findings.
Methods: Patients who had EBUS for PPLs were analyzed and compared on the EBUS imaging characteristics and clinical data. The malignancy prediction model was established by the logistic equation of probability of malignant PPL based on the data of 135 patients.

Objective: To evaluate the role of non-real-time endobronchial bronchoscopy ultrasound(EBUS) assisted transbronchial lung biopsy (TBLB) in diagnosing peripheral pulmonary lesions (PPL).
Methods: One hundred and five patients [68 males and 37 females, mean age (59 ± 12) years, ranged from 39 - 81 years] with PPL confirmed by computered tomography (CT) were recruited in this study between June 1st 2011 and March 1st 2012. All cases received bronchoscopy examinations and presented with roughly normal results.
Background: Patients with central tracheobronchial benign or malignant lesions who have not recieved surgical treatment can be treated by interventional techniques, such as laser, afterloading radiotherapy, cryotherapy, photodynamics treatment, radiofrequency ablation and stenting, etc. The accuracy of the invasive depth of central lesion in tracheobronchial wall plays an important role in making interventional treatment plan. This study used radial probe endobronchial ultrasound (RP-EBUS) scanning to evaluate the accuracy of the invasive depth of central lesions in tracheobronchial wall, and the influence of RP-EBUS scanning in treatment plan making and guidance.

Objective: To find out the correlation between endobronchial ultrasonography (EBUS) images and histologic findings in normal bronchial wall via quantitative analysis of the airway wall thickness and the layer thickness.
Methods: From July 1st to December 31th in 2010, patients underwent lobectomy performed endobronchial ultrasonography (EBUS) before surgery and frost pathological examination after surgery. The layer thickness of EBUS and pathological images were measured.
Zero-valent iron (ZVI) nanoparticles tend to agglomerate, resulting in a significant loss in reactivity. To address this issue, synthesized bentonite-supported nanoscale zero-valent iron (B-nZVI) was used to remove azo dye methyl orange (MO) in aqueous solution. Batch experiments show that various parameters, such as pH, initial concentration of MO, dosage, and temperature, were affected by the removal of MO.

Objective: To study the value of high-frequency electrocautery combined with high-pressure balloon expansion in the treatment of benign airway obstruction.
Methods: Twelve patients with complete airway obstruction received treatment with high-frequency electrocautery and high-pressure balloon expansion, and 6 months of follow-up was performed.
Results: After the initial treatment, the rate of airway obstruction relief exceeded 50% in 8 patients, who showed lung recruitment and an increased dyspnea index, suggesting total effectiveness; one patient showed mild improvement with airway stenosis relief by less than 50% (the upper-left lobe remained obstructed).

Objective: To describe the endobronchial ultrasonographic characteristics and the cut-off value for diagnosis of peripheral lung cancer, and therefore to evaluate its diagnostic value.
Methods: During June 1st, 2005 and June 30th, 2006, 78 patients with peripheral pulmonary lesions were enrolled. The lesions were all detectable by endobronchial ultrasonography (EBUS) and a final diagnosis was made.

Vitellin (Vt) and vitellogenin (Vg) profiles were analyzed in Pteromalus puparum, a pupal endoparasitoid of Pieris rapae. Non-denaturing and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analyses indicated that both native Vt and Vg were likely 370 kDa in size, consisting of two subunits of approximate 206 and 165 kDa. An indirect double antibody enzyme-linked immunosorbent assay (ELISA) for monitoring hemolymph Vg and ovarian Vt levels was developed using a monoclonal antibody and a polyclonal antibody made specially against P.
