[The design of no-power combination manual/foot control suction apparatus].

In this paper, one kind of suction apparatus is introduced, which could use manual, foot control and control combination. The design mentality, realization method, installation constitution and application method are also described. It is suitable to the nonmotile source condition and transportation situation, adapting easily to environment, and getting into favour with the medical staff and field first-aid personnel.

[Repair of peripheral nerve defect by a scroll of amnion derivative compound with cultured autogenous Schwann cell in a rat model].

Objective: To test a nerve bridge substitute for peripheral nerve repair by tissue-engineering approach.

Methods: An artificial nerve fabricated with a scroll of amnion derivative (ZQ membrane) and cultured autogenous Schwann cell was sutured to bridge sciatic nerve defect of 2.5 cm in length in rats.

Intestinal colonization with Candida albicans and mucosal immunity.

Aim: To observe the relationship between intestinal lumen colonization with Candida albicans and mucosal secretory IgA (sIgA).

Methods: A total of 82 specific-pathogen-free mice were divided randomly into control and colonization groups. After Candida albicans were inoculated into specific-pathogen-free mice, the number of Candida albicans adhering to cecum and mucosal membrane was counted.
