[Effect of dust deposition collection methods on collection efficiency].

There are lots of dust deposition collection methods on dust deposition, but there is no standard field observation method. At present, researchers have studied dust deposition using different methods in this issue, but due to the different observation method and collection efficiency, the research results are incomparable. The efficiency of the standard dust deposition gauge including dry, wet, net, net and glass ball and slowing speed methods was studied in the Tengger Desert.

The union of anti-CD34 antibody can improve the performance of drug-eluting stents.

Objectives: The authors investigate whether the combination of anti-CD34 antibody with DES is win-win cooperation.

Background: DES may reduce the risk of restenosis compared to bare-metal stents (BMS), but they were found to inhibit the healing process of intima.

Methods: Fifteen BMS, 17 DES, and 16 combined anti-CD34 antibody and DES were randomly implanted in the coronary arteries of 22 minipigs.

[The research actualities of drug eluting-stents and the developing trend].

The development of drug eluting-stents has been a breakthrough for the prevention of PCI postoperative restenosis, and the correlative researches have not yet stopped and are still the focus of the world. We review, in this article, the history of drug eluting-stents researches, analyze the research actualities and the problems existing, and forecast the developing trend in the future.
