[Treatment of shearing-type and comminuted talar body fractures].

OBJECTIVE: To study the treatment and therapeutic effects in the shearing-type and comminuted talar body fractures. METHODS: From October 1988 to September 2005,34 patients with shearing-type or comminuted talar body fractures were followed up. There were 19 males and 15 females ranged from 13 to 55 years (averaged 28.8 years). The disease course ranged from 3 to 14 days (averaged 6.0 days). Ten patients with a displacement of no more than 3 mm were treated with plastic cast. Eighteen patients were treated with open reduction and internal fixation, 6 patients were treated with joint fusion. The assessment of clinical efforts depend on patients' ache, active range of the joint and limp. RESULTS: The mean follow up was 5.04 years (ranged from 3 to 19 years). All the patients were healed. The clinical outcomes were evaluated according to Hawkins evaluation score in which ache, active range of the joint and limp was respectively acssessed. There were 6 patients reached an excellent result, 9 good, 11 fair and 8 poor. Fifteen patients had osteonecrosis, 18 patients had traumatic arthritis of ankle joint, and 14 patients had traumatic arthritis of subtalar joint. CONCLUSION: Patients whose displacement of fracture is not more than 3 mm should be treated with plastic cast. Operation and internal fixation should be performed in patients whose displacement of fracture is more than 3 mm after close reduction. Joint fusion should be performed in patients whose talar body fracture is comminuted severely and the surface of joint can not be repaired. The patients of talar body scissored fracture or comminuted fracture has bad prognosis.

[Separation and refine of Xiaoyao Pill by macroporous adsorption resin].

OBJECTIVE: To search for the method used in refining Xiaoyao Pill by macroporous adsorption resin, 12 types of macroporous adsorption resin were optimized. METHOD: Static and dynamic adsorption test and de-adsorption test were carried out to screen the best macroporous resin. The single factor test was applied to optimize the manipulation parameters of macroporous resin. RESULT: The macroporous resin D-101-1 possessed the strongest adsorption ability, in addition to an easy de-adsorption property. CONCLUSION: The D-101-1 type macroporous adsorption resin shows better comprehensive adsorption property. It is available for the refine Xiaoyao Pill.
