Comparative study of cryorecanalisation and cryoablation using flexible bronchoscopy for the treatment of endobronchial tuberculosis.

To compare the efficacy and safety of cryorecanalisation and cryoablation using flexible bronchoscopy for the treatment of tumor-like endobronchial tuberculosis (EBTB). Patients with tumor-like EBTB (104) were randomly divided into a cryorecanalisation (54 patients) or cryoablation (50 patients) group to assess the differences in efficacy and complications between the treatments. The cryorecanalisation and cryoablation treatments' therapeutic efficacies were 81.

Carbon deposition mechanism of molten salt cleaning and optimization of multicomponent molten salt formula for remanufacturing.

In remanufacturing engineering, cleaning is the key factor for subsequent blank inspection and parts repair. Molten salt has the characteristics of low viscosity, good fluidity, and strong chemical stability. Salt bath cleaning can be comprehensively applied to remove various organic pollutants.

Research on the Effect of Molten Salt Ultrasonic Composite Cleaning for Paint Removal.

Aiming at paint removal on hydraulic cylinder, the effect of molten salt ultrasonic composite cleaning was studied. First, the mechanism of molten salt cleaning and ultrasonic cleaning was reviewed. To further describe the composite cleaning mechanism, the components and internal structure of paint were analyzed by scanning electron microscopy and Fourier transform infrared.

Effect of poly-methyltriethoxysilane on the waterproof property of starch/fiber composites with open cell structures.

Novel starch/fiber composites with open cell structures were proposed through thermo-cavity molding. To overcome the disadvantage of the water sensitivity of the resulting composites, poly-methyltriethoxysilane (PTS) was added as a waterproofing agent. The results showed that the addition of PTS improved the waterproof property of the composites.

Effects of one-hour training course and spirometry on the ability of physicians to diagnose and treat chronic obstructive pulmonary disease.

Backgrounds: In China, the prevalence of chronic obstructive pulmonary disease (COPD) in persons 40 years of age or older is estimated at 8.2%, but this is likely a substantial underestimate.

Methods: Eight secondary hospitals which didn't have spirometries were chosen randomly in Hunan province of central south China.

Fluorofenidone offers improved renoprotection at early interventions during the course of diabetic nephropathy in db/db mice via multiple pathways.

Diabetic nephropathy (DN) remains the leading cause of end-stage renal disease (ESRD), a situation that is in part attributable to the lack of effective treatments. Fluorofenidone is a newly developed reagent with anti-fibrotic activity. While fluorofenidone was previously demonstrated to possess renoprotection from DN pathogenesis in db/db mice, the protective process and its underlying mechanisms have not been well studied.

Chronic obstructive pulmonary diseases related health resources allocation in hunan province of china.

Background: Information about Chronic obstructive pulmonary diseases (COPD)-related health resources allocation in China is very limited. The aim of the study was to explore the distribution of COPD-related health resources allocation among different levels public hospitals (PHs) in Hunan Province of central south China.

Methods: We randomly collected data from 57 Public Hospitals (PHs) at 3 different levels in Hunan province as well as 893 pulmonary physicians (PPs) who worked there in 2009.

[Expression of human-mouse chimeric antibody directed against Chikungunya virus with site-specific integration system].

Aim: To obtain CHO/dhfr(-) cells line with integrated FRT sequence in the chromosome transcription active site and to express human-mouse chimeric antibody directed against Chikungunya Virus by using the cell line.

Methods: The fusion gene of FRT and HBsAg was constructed by PCR and cloned into the MCS of pCI-neo to construct pCI-FRT-HBsAg. The pCI-FRT-HBsAg was transfected into CHO/dhfr(-) cells and cell clones with high expression of HBsAg were screened by detecting the amount of HBsAg with ELISA.
