RESUMO
Objective We reported 16 eosinophilic fasciitis (EF) patients with eosinophilic fasciitis and performed a systematic review of the literature to improve the disease awareness.Methods The clinical course of 16 patients with eosinophilic fasciitis at the Peking Union Medical College Hospital were described,inclu-ding demographic data,clinical manifest-ations,laboratory tests,pathology and treatment.Results The mean age at diagnosis was (47±8) years,with 13 female and 3 male patients.Three cases had exertion or strenuous sports before the onset of EF.Positive ANA was noted in 6 of 12,positive RF was noted in 3 of 10,hyper-gammaglobulinemia was noted in 6 of 7,elevated IgG was noted in 8 of 13,peripheral blood eosinophilia was noted in 10 of 16,while thrombocytopenia was found in one patient.Conclusion Based on this and other reported cases in the literature,EF may be a kind of autoimmune disease.Genetic influence and environ-mental factors are involved in the development of this disease.Systemic involvement is rare.In general,corticosteroids and immunosuppressive are effective in EF.
RESUMO
Objective To study the effects of melatonin (MT) on hepatic tissue of autoimmune hepatitis (AIH). Methods AIH model rats were divided randomly as model group, MT group and pig hepacyte growth factor (pHGF) group, to observe the pathological changes of hepatic tissue of the three groups. Results Hepatic tissue inflammation and accrementition graded of elastic fibers, reticular fibre, collagenous fibrils of MT group [(0.97±0.16),(1.09±0.17),(1.31±0.17)] were much lighter than model group [(1.55±0.18),(2.00±0.14),(3.00±0.14)](all P<0.01). The expression of VEGF was weaker in MT group than in pHGF group. There was no distinct difference between MT group and pHGF group. Conclusion MT can obviously improve the pathological changes of hepatic tissue of rats with AIH.
