Objective To study the effect of rehabilitation in stroke patients with dysphagia. Methods 31 cases with dysphagia were randomly divided into rehabilitation group (17 cases) and control group (14 cases). Two groups were given same basic therapy on the whole, while the early rehabilitation was performed on the patients in rehabilitation group three times a day for 3 weeks. We compared assessment score of dysphagia by VFSS (videofluoroscopic swallowing study), and observed serum potassium, sodium, albumin levels and the incidence of inhalation-pneumonia in two groups before and after treatment. Results VFSS score (7.2?2.1) of rehabilitation group was markedly higher than before treatment (4.0?1.9) and control group (4.7?2.1)(all P0.05).Conclusions Rehabilitation has a remarkable effect on stroke patients with dysphagia.

Purpose To investigate the clinicopathologic features of calcifying aponeurotic fibroma (CAF). Methods The clinical and pathologic profiles of 6 cases of CAF were retrospectively analyzed. Results CAF appeared a firm, painless and slowly growing mass with a predilection for the distal portions of the extremities in young children and adolescents. Microscopically, the tumor consis-ted mainly of benign appearing spindle cells, chondroid cells and calcific debris. Immunohistochemically, the tumor cells were positive for vimentin, HHF-35, S-100, Calponin and CD68. Conclusion CAF is a rare, locally aggressive fibroblastic lesion. It can make an accurate diagnosis by integrating the clinical location with histopathological features. Repeated minor trauma to the extremities and some embryologic cell nests maybe its pathogenesis.

Objective:To evaluate the expression of CXCR4 and the migration rate of bone marrow stromal CD34+cells in differ-ent risk groups with myelodysplastic syndromes (MDS) using correlation analysis. Methods: Forty MDS patients were divided into low-and high-risk groups based on the International Prognosis Scoring System (IPSS). The former was composed of 20 patients with IPSS<1.5, whereas the latter was composed of 20 patients with IPSS≥1.5. Bone marrow (BM) samples of these patients and 10 nor-mal controls were collected. CD34+cells were separated and purified. The expression of CXCR4 was determined by flow cytometry. The migration rate of CD34+cells on the chemotactic effect of SDF-1αand on the effect of bone marrow stromal cells were measured. Results:The expression rate of CXCR4 was higher in the high-risk MDS group than in the low-risk and control groups (P<0.000 1). No significant differences existed between the low-risk and the control groups (P>0.05). The migration rate of CD34+cells on the ef-fects of SDF-1αand marrow stromal cells were significantly increased in the high-risk MDS group compared with those in the low-risk and control groups (P<0.000 1). Migration rate of CD34+cells on the effect of marrow stromal cells was positively correlated with CX-CR4 expression (P=0.000 1). Conclusion:The CXCR4 expression and migration rates of CD34+cells on the effect of marrow stromal cells are significantly higher in the high-risk MDS group than in the low-risk group. Migration rate has a positive correlation with the CXCR4 expression, which further indicates that MDS is a heterogeneous group of hematopoietic stem cell malignancies. The expres-sion and function of SDF-1 and its receptor CXCR4 differ within each group with various risks. SDF-1 and CXCR4 may be involved in MDS pathogenesis.
