Objective To improve the recognization of hip joint lesion in ankylosing spondylitis and it's related factors.Methods Pelvis computed radiography(CR) and HLA-B27 were examined in 100 cases of ankylosing spondylitis proved by clinical.Results 58% cases appeared differed degree of narrowing of the interticular space,osteoporosis on head of femur and acctabulum,cystis under the surface of acctabulum and joint inosculated.This probability was higner at thoe patients that had diaease at youthful or HLA-B27(+).Conclusion Hip joint lesions of ankylosing spondylitis appear characteristic signs in CR.It relates with the age that the disease come on and HLA-B27.

Designable experiment refers to such an experiment that students apply their knowledge and experiment skills to design and prepare experimental materials,instruments,means and procedures based on specific purpose and requirements,and finish the formal experiment by themselves.Through designable experiment,students' integration capability such as applying knowledge,manual operation and handling problem are cultured.We explore setting up designable experiment in the course of clinical hematological examination,and evaluate the effectiveness of teaching.

Objective To explore the expressions of stromal cell derived factor 1 α (SDF-1α) and cysteine-X-cysteine chemokine receptor 4 (CXCR4) in the peripheral blood of patients with systemic lupus erythematosus (SLE).Methods Forty hospitalized SLE patients were recruited and twenty healthy volunteers were enrolled as normal controls.The percentage of CD3+CD4+CXCR4+,CD3+CD8+CXCR4+ and the plasma concentration level of SDF-1α in the control group and SLE patients were detected by flow cytometry and ELISA.The relationship between SDF-1α/CXCR4 and SLEDAI was explored.Kruskal-Wallis H,Pearson's and Mann-Whitney U test were used for statistical analysis.Results the expression of SDF-1α [329 (127,539) pg/ml] and CXCR4 [CD3+CD4+CXCR4+:4.20(2.01,6.35)％,CD3+CD4+CXCR4+:2.70(1.68,4.20)％] were significantly elevated in SLE patients when compared to the normal controls (Z=-6.277,-5.707,-4.885,respectively,all P=0.000),and were significantly increased in highly active SLE patients than less active SLE (Z=-5.414,-5.256,-5.312,P＜0.01).The expression of SDF-1α and CXCR4 in the butterfly erythema group,anemia group and proteinuria group were significantly higher than the normal group (P＜0.05).Both SDF-1αand CXCR4 were positively correlated with SLEDAI (r=0.857,0.830,0.861,respectively,all P＜0.01).Conclusion The expressions of SDF-1α and CXCR4 increase significantly in the peripheral blood of SLE patients and there is close relationship between SDF-1α/CXCR4 and disease activity,organ damage.The results of this study suggestthat SDF-1α/CXCR4 may play an important role in the pathogenesis of SLE.

OBJECTIVES: To examine the changes of coenzyme Q10 (CoQ10) and β-galactosyl transferase specific chaperone 1 (C1GALT1C1) in brain of rats with ischemic injury at different time points and to explore the protective mechanism of ultrashort wave (USW) on ischemic brain injury. METHODS: Fifty SD rats were randomly divided into 5 groups (=10 per group): a sham group (control group) and 4 experimental group (ischemia for 2 h). The 4 experimental groups were set as a model 1 d group, a USW 1 d group, a model 3 d group and a USW 3 d group, respectively. Five rats were randomly selected for 2,3,5-triphenyltetrazoliumchloride (TTC) staining in each experimental group, and the remaining 5 rats were subjected to Western blotting and real-time PCR. The percentage of cerebral infarction volume and the relative expression level of CoQ10 and C1GALT1C1 in the brain were examined and compared. RESULTS: The infarct volume percentage after TTC staining was zero in the sham group. With the progress of disease and USW therapy, the infarct volume percentage was decreased in the experimental groups (all <0.05); Western blotting and real-time PCR showed that the relative expression level of CoQ10 in the sham group was the highest, while in the experimental groups, the content of CoQ10 showed a upward trend with the extension of disease and USW therapy, with significant difference (all <0.05). The relative expression level of C1GALT1C1 in the sham group was the lowest, but in the experimental groups, they showed a downward trend with the extension of disease and USW therapy, with significant difference (all <0.05). CONCLUSIONS Non-caloric USW therapy may upregulate the expression of CoQ10 to suppress the expression of C1GALT1C1 in rats, leading to alleviating cerebral ischemic reperfusion injury.
