Biodegradable Biomaterial Arterial Stent in the Treatment of Coronary Heart Disease.

This study aims to evaluate the clinical application value of two materials, drug-eluting stent, and biodegradable stent, in the treatment of coronary heart disease. The results show that the therapeutic effects of drug-eluting stents and biodegradable stents are similar. Both treatment methods have high safety and effectiveness.

Transcriptome Profiling Combined With Activities of Antioxidant and Soil Enzymes Reveals an Ability of sp. CFA to Mitigate -Hydroxybenzoic and Ferulic Acid Stresses in Cucumber.

Continuous-cropping leads to obstacles in crop productivity by the accumulation of -hydroxybenzoic acid (PHBA) and ferulic acid (FA). In this study, a strain CFA of was shown to have a higher PHBA- and FA-degrading ability in media and soil and the mechanisms underlying this were explored. Optimal conditions for PHBA and FA degradation by CFA were 0.

The Effects of Acid Etching on the Nanomorphological Surface Characteristics and Activation Energy of Titanium Medical Materials.

The purpose of this study was to characterize the etching mechanism, namely, the etching rate and the activation energy, of a titanium dental implant in concentrated acid and to construct the relation between the activation energy and the nanoscale surface topographies. A commercially-pure titanium (CP Ti) and Ti-6Al-4V ELI surface were tested by shot blasting (pressure, grain size, blasting distance, blasting angle, and time) and acid etching to study its topographical, weight loss, surface roughness, and activation energy. An Arrhenius equation was applied to derive the activation energy for the dissolution of CP Ti/Ti-6Al-4V ELI in sulfuric acid (H₂SO₄) and hydrochloric acid (HCl) at different temperatures.

[Determination of the eliminating ratio of TCM polysaccharide to hydroxyl radical by kinetic fluorescent spectrophotometry].

Objective: To explore reaction dynamic of hydroxyl radical (*OH) and salicylic acid,and to determine the elimination ratios of TCM polysaccharide to *OH by kinetic fluorescent analysis.

Methods: The impact dynamics factors of this reaction were studied by fluorescent, such as the reaction of concentration, reaction time and temperature. The dynamical equation was built, a kinetic fluorescent spectrophotometry based on the reaction was developed to determine the elimination ratio.

[Detection of thromboxane B2, 6-keto-prostaglandin F1alpha and anticardiolipin antibody in patients with obstructive sleep apnea-hypopnea syndrome].

Objective: To observe the changes of thromboxane B(2) (TXB(2)), 6-keto-prostaglandin F1alpha (6-K-PGF1alpha) and anticardiolipin antibody (ACA) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) before and after institution of nasal continuous positive airway pressure (nCPAP).

Methods: Sixty cases of OSAHS confirmed by polysomnography (PSG) were selected as the trial group, and 20 normal donors without OSAHS were recruited as the control group. Nineteen patients with severe OSAHS were treated by nCPAP.
