[Arthroscopic surgery on traumatic anterior instability of shoulder].

Objective: To study the principle of arthroscopic surgery and its clinical importance on the traumatic anterior shoulder instability.

Methods: From September 2002 to May 2005, 18 patients with injury history of 15 weeks averagely, were involved in the study. Twelve of the patients had a history of sports injuries, 5 had shoulder injuries during working time, and 1 had a traffic accident.

[The treatment method of arthroscopic repair of meniscus tear].

Objective: To investigate the result of the arthroscopic repair of the meniscus tears with the absorbable sutures.

Methods: From June 1998 to May 2003,the meniscus tears in 110 patients (78 males, 32 females; aged 14-66 years, averaged 27.5 years) were repaired with absorbable sutures under an arthroscope.

[Clinical study on double contrast CT diagnosis of traumatic anterior shoulder instability].

Objective: To evaluate the clinical importance of double contrast CT diagnosis of traumatic anterior shoulder instability.

Methods: Forty-eight patients underwent double contrast CT scan. With the guide of CT scan, anterior arthrocentesis of the shoulder was performed and 4 ml of 76% urografin was injected into the joint and then 10 ml of filtrated air was injected.

Parallelization of MRCI based on hole-particle symmetry.

The parallel implementation of multireference configuration interaction program based on the hole-particle symmetry is described. The platform to implement the parallelization is an Intel-Architectural cluster consisting of 12 nodes, each of which is equipped with two 2.4-G XEON processors, 3-GB memory, and 36-GB disk, and are connected by a Gigabit Ethernet Switch.

On the interconversion pathway of HBO<-->BOH.

The potential energy surfaces have been constructed for the 1A', 3A', and 3A" states of HBO by using the multireference perturbation theory with the basis set cc-pVTZ (6d,10f). Two stationary points and a transition state have been characterized on all the three surfaces, which are in good agreement with available experiments and previous calculations. The interconversion pathways from metastable boron hydroxide BOH to the considerably more stable HBO are expounded based on the nature of the surfaces.

[The protection of seed oil of Hippophae rharmnoides on ischemic cerebral infarction in rats].

Objective: To study the protection of seed oil of Hippophae rhamnoides on ischemic cerebral infarction in rats and the mechanism of the action.

Method: Focal cerebral ischemia model was made by middle cerebral artery occlusion(MCAO) in rats. Behavior obstacles of rats were observed.
