Objective To summarize the keypoints of clinical diagnosis of chondroblastoma and the experience on the treatment Methods The clinical materials of 16 cases(11 males,aged from 12 to 26 years)from June 1992 to February 2003 of pathologically diagnosed chondroblastoma were analyzed retrospectively. The tumor located at distal femur in 6 cases,great trochanter in 1 case,proximal tibia in 6 cases,proximal humerus in 2 cases, talus in 1 case. The main symptoms were swelling and painful joint. All the 16 cases were treated with curettage and autologous bone graft from iliac crest. Results Twelve cases were followed up for 6 months to 5 years .averaging 3. S years. All the bone graft healed well. One case., recurred 2 years after the initial curettage and was treated with curettage again. No recurrence occurred at the last follow-up 6 months after the second curettage. The function of the involved joints was nearly normal in all cases except for one case with slight limitation of knee flexion. Conclusions Mastering the image and clinical characteristics of chondroblastoma can avoid misdiagnosis and mistreatment Curettage can control the tumor satisfactorily. Postoperative rehabilitation can improve the function of the involved limb.

Objective To investigate any potential and independent demographic and serologic risk factors contributing to bone destruction in patients with rheumatoid arthritis ( RA) . Methods A total of 445 patients with RA were recruited in this study. Three autoantibodies including rheumatoid factor ( RF) , anti-cyclic citrullinated peptide antibody ( anti-CCP antibody) and anti-citrullinated alpha-enolase peptide 1 antibody ( anti-CEP-1 antibody) were quantified by using specific ELISA kits. The hand radiographs of all subjects were graded by using the modified Sharp/van der Heijde score ( Sharp score) . The potential and in-dependent risk factors were assessed by using univariate linear regression analyses and the stepwise multiple regression analysis, respectively. Results Based upon the univariate regression analyses, 7 covariates were identified as the potential risk factors for bone destruction in patients with RA, which were female (β=0. 100, P=0. 035), longer disease duration (β=0. 498, P=3. 26×10-29), RF (β=0. 096, P=0. 042), younger age at onset (β=-0. 312, P=1. 60 × 10-11 ), anti-CCP antibody positive (β=0. 202, P=1.74×10-5), anti-CEP-1 antibody positive (β=0.148, P=0.017) and positive for either anti-CCP or anti-CEP-1 antibodies (β=0. 157, P=1. 42×10-3). However, smoking (β=-0. 121, P=0. 018) were identi-fied as the potential protective factors. The multiple regression analysis indicated that the longer disease du-ration (P=2. 24×10-15) and anti-CCP antibody positive (P=0. 012) were independent risk factors for bone destruction. Conclusion Female, longer disease duration, younger age at onset, RF, anti-CCP and anti-CEP-1antibodies are potential risk factors for bone damage in patients with RA. Moreover, longer disease du-ration and anti-CCP antibody are two independent risk factors contributing to bone destruction in RA.

Objective To discuss the influence of motor imagery therapy on the recovery of the stroke patients with aphasia.Methods Sixty cases of stroke patients with aphasia were divided into the treatment group and the control group according to the odd and even of last number.The single number was set into the control group.The double number was given to the treatment group.There were thirty patients in each group.Both groups received the conventional drug treatment and routine care of the Department of Neurology.On this basis,from the second day in hospital,the treatment group received the speech rehabili tation training with motor imagery therapy.Aphasia assessment was done for the two groups on the first day in hospital with CRRCAE.On the first day and after receiving ten-day treatment with motor imagery therapy,the grade of the severity for aphasia of Boston Diagnostic Aphasia Examination (BDAE) was done to assess the severity of aphasia in two groups.The scores of the two groups were compared.Results Before the treatment,there was no significant difference between the two groups.After receiving ten times treatment,both the two groups were improved.Compared with the control group,the treatment group became better.There was statistically significant difference between the two groups.Conclusions For the stroke patients with aphasia,motor imagery therapy has significant effect on their recovery.
