[Application and exploration of micro-class combined with flipped classroom in cardiopulmonary resuscitation teaching for dental students].

Purpose: To explore the application of micro-class combined with flipped classroom in cardiopulmonary resuscitation teaching for dental students.

Methods: The experimental group included 46 students from grade 2014 in college of stomatology, Shanghai Jiao Tong University. The control group included 45 students from grade 2013.

The stability and controlled release of I-ascorbic acid encapsulated in poly (ethyl-2-cyanoacrylate) nanocapsules prepared by interfacial polymerization of water-in-oil microemulsions.

The L-ascorbic acid (AA) was encapsulated into biodegradable and biocompatible poly(ethyl-2-cyanoacrylate) (PECA) nanocapsules by interfacial polymerization of water-in-oil (W/O) microemulsions. The influences of surfactant concentration, pH value of the dispersed aqueous phase, and W/O ratio on nanocapsule size were discussed. The stability and in vitro release of encapsulated AA were also investigated.

Alpinetin inhibits lung cancer progression and elevates sensitization drug-resistant lung cancer cells to cis-diammined dichloridoplatium.

Objective: Alpinetin is a novel flavonoid that has demonstrated potent antitumor activity in previous studies. However, the efficacy and mechanism of alpinetin in treating lung cancer have not been determined.

Methods: We evaluated the impact of different doses and durations of alpinetin treatment on the cell proliferation, the apoptosis of lung cancer cells, as well as the drug-resistant lung cancer cells.

[Experimental use of pulmonary flap with alloy stent for the reconstruction of trachea and esophagus].

Objective: To study the feasibility of applying autogenous pulmonary tissue flap with alloy stent to correct the defects of trachea and esophagus.

Methods: Twenty-four dogs were divided into tracheal and esophageal groups. Bronchus was ligated to prepare a pulmonary flap.

[Clinical application and animal experiment of thoracic tracheal reconstruction by using pulmonary tissue flap].

Objective: To study the usability of pulmonary tissue flap in the reconstruction of the thoracic trachea.

Methods: Over half perimeter anterior and posterior wall and 6 to 8 tracheal cartilagious rings of dog trachea were resected. The nickel-titanium alloy mesh stent was placed inside the lumen for repair of the defect of the tracheal wall by nearby pulmonary tissue flap with the vascularized segment.
