ABSTRACT

Objective Thymoma is associated with autoimmune diseases. We retrospectively analyzed the clinical characteristics of thymoma complicated systemic lupus erythematosus (SLE). Methods Patients were from Qilu Hospital Shandong University between June 2004 and June 2014, and satisfied classification criteria of American College of Rheumatology (ACR) classification criteria 1997 for SLE. Thymoma was diagnosed by chest CT scan. Results Nine cases were of thymoma complicated with SLE, with the male:female ratio of 1∶8. The age of SLE onset was (48±19) years, age of thymoma discovery was (47±19) years. The follow-up period was 3 to 10 years. Three cases (33%) were benign thymoma and underwent thymectomy and verified by histopa-thology test. One case presented thymoma 9 years after SLE, 5 cases (56%) presented SLE and thymoma simultaneously, 3 cases (33%) presented SLE after thymectomy. Clinical manifestations of SLE included 4(44%) skin lesions, 8(89%) polyarthritis, 5(56%) nephritis, 3(33%) leukocytopenia, 3(33%) throm-bocytopenia, 2 (22%) of interstitial pneumonia, 4 (44%) pleural effusion, no neuropsychiatric systemic lupus erythematosus. Nine cases (100%) were ANA positive, 7 (78%) were anti-dsDNA positive. Conclusion SLE complicated thymoma usually occurs in relatively older age, tend to present with multi-systemic presentations, and high percentage of anti-dsDNA positivity.

ABSTRACT

To investigate the neuronal migration and synthesis of peptidic neurotransmitters in vitro, neuromuscular co-cultures of nodose ganglia and cardiac muscle cells of Wistar rats were established. The living cells of co-cultures were observed with an inverted contrast microscope at different culture age. At 72 h and 96 h of culture age, the neuromuscular co-cultures were examined by Holmes' reduced silver staining technique for observing the neuronal migration. Immunohistochemical staining method was used for investigating the synthesis of peptidic neurotransmitters- substance P (SP) and calcitonin gene-related peptide (CGRP). The neuronal morphorlogical maturation in neuromuscular co-cultures seems at 72 h of culture age in terms of the observation of living cells and Holmes' reduced silver staining technique. SP- and CGRP-immunoreactive neurons were observed in neuromuscular co-cultures at 96 h of culture age but not 72 h. The results indicate that the neuronal morphological maturation can not represent the maturation of neurotransmitter synthesis. The synthesis of neurotransmitters is not maturated in the neuromuscular co-cultures until 96 h of the culture age.

ABSTRACT

Objective To determine health related quality of life (QOL) of patients with systemic lupus erythematosus (SLE) and to identify the factors affecting QOL. Methods One hundred and fifty-one consecutive patients with SLE were separated into different groups according to the type or stage of disease. Health status were measured by 1 health transition (HT) and 8 composite scales of the medical outcomes study short form-36 (SF-36). The mean scores for each subscale of the SF-36 for patients with SLE in China were compared to those of a health population in China and of foreign SLE patients.The effect of patients′age,sex,education level,disease duration,disease activity (assessed by SLEDAI score),and organ damage(assessed by SLICC/ACR DI) and treatment were analyzed. ANOVA, rank sum test and correlation analysis were applied for statistical analysis. Results Patients with SLE had significantly lower HT and mean scores in each subscale of the SF-36 compared to those of a health population in China,while the scores in such subscales as physical functioning (PF), bodily pain (BP), vitality (VT), role-emotional (RE) and mental health (MH) were higher than those of foreign SLE patients. The mean scores of those patients with lupus nephritis and center neural lupus or in active state were lower than those not or those in steady-going. The SLEDAI score and SLICC/ACR DI were the most important elements that affected the QOL in SLE patients and showed obviously negative correlated with one′s scores in SF-36. The glucocorticoid dose of patients was closely negatively correlated with one′s scores. The latter were also associated with age, education level and disease duration. Conclusion The health status of patients with SLE is mainly associated with disease activity,damage and therapy. The SF-36 is a valid instrument for measuring the health related QOL in SLE.
