ClC-3 promotes angiotensin II-induced reactive oxygen species production in endothelial cells by facilitating Nox2 NADPH oxidase complex formation.

Recent evidence suggests that ClC-3, a member of the ClC family of Cl channels or Cl/H antiporters, plays a critical role in NADPH oxidase-derived reactive oxygen species (ROS) generation. However, the underling mechanisms remain unclear. In this study we investigated the effects and mechanisms of ClC-3 on NADPH oxidase activation and ROS generation in endothelial cells.

[Research on Pyrolysis Process of Kevlar Fibers with Thermogravimetric Analysis coupled and Fourier Transform Infrared Spectroscopy].

Modern industrial application and technologies require materials with superior mechanical and thermal properties. Kevlar fibers have been known as fibrous materials with good properties of high strength and high decomposition temperature which have become a hot research field in recent years. The properties of fibrous materials depend on their structures and compositions.

[Surgical treatment for incisions fat colliquation or infections at early stage after operation of lumbar disc herniation].

Objective: To explore the reason, key diagnosic point and therapeutic method of the incisions fat colliquation or infections at early stage after operation of lumbar disc herniation.

Methods: From July 2007 to May 2012, clinical data of 11 patients with incision fat liquefaction or early infection after lumbar discectomy were retrospectively analyzed. There were 5 males and 6 females with an average age of 43.

[Case-control study on measurement of coracoclavicular and acromioclavicular ligament injuries during internal fixation operation for the treatment of fresh acromioclavicular joint dislocation of Tossy type III].

Objective: To study measurement methods of acromioclavicular and coracoclavicular ligament injuries,its therapeutic effects and complications during internal fixation operation for the treatment of fresh acromioclavicular joint dislocations of Tossy type III.

Methods: From July 2003 to May 2012,127 patients with acromioclavicular joint dislocations of Tossy type III were treated with wire fixation from coracoid process to clavicle or hook-plate fixation. The patients were divided into group A (63 cases) and group B (64 cases) according to whether acromioclavicular ligament and coracoclavicular ligament were repaired or not.

[Studies on relics conservation by diffuse reflectance spectroscopy].

A diffuse reflectance spectroscopic method was developed to investigate relics conservation with a self-made fiber optics reflectance spectrophotometer. With this technique (1) identifying pigments on the color relics was done by comparing the shapes of reflectance spectra and the positions of reflectance peaks or first derivative peaks with those of related standard pigments; (2) changes of surface states of metals were monitored. From the investigation on the reflectance spectra of copper and its rust product, we can easily get some information about the metal surface, so diffuse reflectance spectroscopy shows special function in the research on metal surface; (3) the diffuse reflectance spectroscopic characteristics of the materials used in protection and restoration of cultural heritages were studied, which can help us choose proper protecting and restoring materials.
