[Comparison the effects between anatomical locked plate in combination with coracoclavicular ligament reconstruction and clavicular hook plate for the treatment of Neer II b distal clavicle fractures].

Objective: To compare the therapeutic effects between anatomical locked plate combined with coracoclavicular ligament reconstruction and clavicular hook plate for treatment of distal clavicle fracture of Neer type II b.

Methods: From August 2010 to August 2013, 42 patients with Neer II b distal clavicle fractures were randomly divided into two groups as group A and group B. In group A, there were 22 cases including 14 males and 8 females with an average age of (44.

[The recent development of fiber-optic chemical sensor].

The present article provides a brief review of recent research on fiber-optic chemical sensor technology and the future development trends. Especially, fiber-optic pH chemical sensor, fiber-optic ion chemicl sensor, and fiber-optic gas chemical sensor are introduced respectively. Sensing film preparation methods such as chemical bonding method and sol-gel method were briefly reviewed.

Objective: To analyze the indication of arthroscope by examining the correlations between cartilage injury degree confirmed by MRI and postoperative effect.

Methods: From Aug. 2005 to April 2008, 87 cases with knee osteoarthritis were treated by arthroscopes including 44 males and 43 females,aged from 16 to 67 years (means 46.

[Suture menisci with epidural transfixion pin to treating acute meniscus tear under arthroscope].

Objective: To study the utility and effect of suturing menisci with epidural transfixion pin to treating acute meniscus tear under arthroscope.

Methods: Twenty-two cases with acute meniscus tear were selected, in which 18 were male and 4 were female,aged from 17 to 42 years with average of 28.5.

Active Src expression is induced after rat peripheral nerve injury.

The non-receptor-type Src tyrosine kinases are key components of intracellular signal transduction that are expressed at high levels in the nervous system. To improve understanding of the cascades of molecular events underlying peripheral nerve regeneration, we analyzed active Src expression in the crushed or cut rat sciatic nerves using a monoclonal antibody (clone 28) that recognizes the active form of Src tyrosine kinases, including c-Src and c-Fyn. Western blots showed that active Src expressed in the normal sciatic nerve transiently increased up to threefolds after both types of injury.
