[Ultrasound-guided needle-knife for trigger finger].

Objective: To explore the efficacy of ultrasound-guided needle-knife with precise three-dimensional stereotactic localization of points for stenosing tenosynovitis of flexor tendon (trigger finger).

Methods: A total of 74 patients were randomly divided into an observation group and a control group, 37 cases in each group. The patients in the observation group were treated with ultrasound-guided intrathecal injection and releasing method of needle-knife, while the patients in the control group were treated with ultrasound-guided intrathecal injection.

[Blood rheology analysis of 23436 samples and establishment of reference range by sitting and lying position].

Aim: To establish reference range of blood theology for different gender by sitting and lying in healthy populations.

Methods: In 31 volunteers blood were drawed in the postures of sitting and lying to measure blood rheology. Data (between July 2002 and July 2006) of 32854 samples (23436 check-up, 6553 out-patient,2865 in-patient) were collected.
