ABSTRACT
Objective To explore the CT appearance of thoracic lymphonodus in AIDS patients with immune reconstitution in-flammatory syndrome(IRIS)after highly active antiretroviral therapy (HAART).Methods The data of thoracic CT in 24 AIDS pa-tients after HAART with enlarged thoracic lymphonodus in IRIS were collected,and the chest CT appearance was analyzed.Results Of the 24 cases of AIDS patients with IRIS after HAART,1 9 cases were complicated with pulmonary tuberculosis,which includ-ed 5 cases with cervical tuberculous lymphadenitis,3 cases were co-infected with bacterium and fungi,1 case was infected by penicil-lium marneffei,1 case by pneumocystis carinii.The enlarged thoracic lymphonodus were primarily located in 4R region(20/24), secondly in 2R region(1 1/24)and 4L region(1 1/24),in which the density was uniform or non-uniform,edge clear or unclear,some parts of lymphonodus were fused together but not calcified.The minor axis of enlarged lymphonodus was 1 1.0-25.0 mm except X region,enhanced uniformly in 2 cases.Obstructive pneumonia and pulmonary consolidation were found in 2 cases with enlarged lym-phonodus,which were located in 10R region.Pleural effusion was found in 13 cases with greatest depth of about 22 mm,pericardial effusion was found in 5 cases with greatest depth of about 24 mm.Conclusion The enlarged thoracic lymphonodus in AIDS patients with IRIS affer HAART are mainly involved in the region of 4R,2R and 4L,with or without pleural effusion and pericardial effusion.
ABSTRACT
Objective To study the therapeutic effect of ankylosing spondylitis treated with sacroiliac joint injection under C-arm X-ray guidance. Methods Four hundred and eighty-three patients of ankylosing spondylitis were divided randomly into two groups according to the treatment method. Four hundred and twenty-one cases were in group A:sacroiliac joint injection under C-arm X-ray, the injection medicine were diprospan or triamcinolone acetonide and methotrexate, and with oral sulfasalazine (SASP) as well. Sixty-two cases were in group B: oral medicion SASP and meloxicam alone without injection. Self-evaluation, finger-to-floor distance, changes in Schober's sign, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) before and after treatment of 3 d, 1 week,2 weeks, 3 weeks, 4 weeks and 3 months were observed. Results Two indicators including self-evaluation and finger-to-floor distance at initial 3 d were significantly lower than those before treatment in group A: (6.18 ±0.55) scores vs. (8.89 ±0.53) scores, (30.10 ±3.94) cm vs. (50.20 ±3.93) cm, P<0.05. Schober's sign and occiput-to-wall distance at 1 week after treatment were significantly lower than those before treatment in group A:(3.44± 0.32) cm vs.(3.19±0.47) cm, (9.49±0.68) cm vs. (10.72±2.36) cm, P<0.05. Two indicators including self-evaluation and finger-to-floor distance at 1 week after treatment were significantly lower than those before treatment in group B:(7.07 ± 0.72) scores vs. (9.08 ±0.46) scores, (48.14 ±5.62) cm vs. (50.84 ±4.33) cm, P<0.05. Schober's sign at 4 weeks after treatment was significantly lower than that than before treatment in group B:(3.49± 0.56) cm vs. (3.22±0.58) cm, P<0.05. Occiput-to-wall distance at 2 weeks after treatment was significantly lower than that before treatment in group B:(9.08±1.54) cm vs. (10.11±1.58) cm, P<0.05. Conclusion The method of C-arm X-ray guided sacroiliac joint injection for treatment of ankylosing spondylitis is effective and feasible.
ABSTRACT
Objective To demonstrate the change in peripheral blood T lymphocyte subgroup and cytokines of Beh?et′s disease (BD). Methods T lymphocyte subgroup was detected by flow cytometry and serum interleukin (IL)-8, sIL-2R, IL-1?, IL-2, IL-6 and TNF-? were assayed by RIA. Results CD4, CD4/CD8, NK of BD decreased evidently and CD8 incrdased. Serum IL-8, sIL-2R increased compared to normal controls. Change of IL-2, IL-6, tumor necrosing factor (TNF)-? , IL-1? showed no statistical significance compared to normal group. Conclusion Change in peripheral blood T lymphocyte subgroup and serum IL-8, sIL-2R can be one of the activity index of BD.
