Objective To study the change and the significance of T-lymphocyte immune function in peripheral blood in population living in arsenic-contaminated area. Methods Fifty-three cases of patients with arsenism symptoms were selected into experimental group, inhabitants who had no chronic arsenism symptoms into control group in the endemic area of Shuocheng District, Shuozhou City, Shanxi Province in 2006. Vein blood samples were taken and analyzed with SAP assay to measure the percentage of CD3+ ,CD4+ and CD8+ T-cells. Results It was found that the percentage of CD3+, CD4+, and CD4+/CD8+ [(41.89 ± 11.58)%, (25.60 ± 9.05)% and 1.02 ± 0.41] in the experimental group was lower than that in the control group [(68.38 ± 7.23)%, (39.17± 4.28)% ,1.69 ± 0.56, t = 13.61,18.72,14.79, all P < 0.05], while there was no statistical differences of CD8+ [(25.30 ± 6.85)%] compared to the control group[(23.54 ± 8.35)%,t = 3.07,P > 0.05]. The gender-related effect of arsenic on CD4+ and CD8+ was found by multiple linear step regression analysis(t = - 3.05, - 4.30, all P < 0.05). In case group, there were no statistical differences in CD3+, CD4+, CD8+ and CD4+/CD8+[(40.65±10.06)%, (24.48 ± 6.29)%, (24.52 ± 8.16)%,0.98 ± 0.25] between males and females [(43.07±12.96)%, (26.77±3.12)%, (26.50 ±9.32)%, 1.07 ±0.41, t = - 0.76,3.05,0.30,2.10, all P > 0.05]. Conclusions The immune function of T-lymphocytes of patients with chronic arsenism has been suppressed. It is of active significance to detect T-lymphocyte subpopulation in peripheral vein in patients with chronic arsenism aiming at estimating the function of cell immune and providing early diagnosis index.

OBJECTIVETo study the treatment and therapeutic effects in the shearing-type and comminuted talar body fractures.

METHODSFrom 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.

RESULTSThe 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.

CONCLUSIONPatients 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.
