RESUMO
Objectives Anticardiolipin antibody (aCL) is an important component of antiphospholipid antibody (aPL) and a marker antibody of antiphospholipid syndrome (aPS). APL is positive in 20% to 40% of patients with systemic lupus erythematosus(SLE). This article investigated the clinical features and prognosis of SLE patients with aCL. Methods From January 1999 to December 2009, 495 cases of SLE patients detected aCL who were hospitalized for the first time in 26 hospitals in Jiangsu Province including Nanjing Drum Tower Hospital were divided into aCL-positive group and aCL-negative group according to the test results. The patients were followed up in survival status, and the demographic characteristics, affected organs, laboratory tests, treatment drugs, and prognosis were compared between two groups. Results 146 of the SLE patients in this group were positive for aCL. The proportion of women in aCL- positive group (96.6%) was significantly higher than that in aCL-negative group (90.8%), and the difference was statistically significant (P<0.05). The proportion of anemia (74.7% vs 61.3%), decreased C3(81.5% vs 71.1%), positive antinuclear antibody(97.2% vs 92.4%), and positive anti-dsDNA antibody (61.9% vs 49.6%) in aCL-positive group were significantly higher than those of aCL-negative group, and the difference was statistically significant (P<0.05). The aCL-positive group received a higher proportion of cyclophosphamide immunosuppressive therapy (39.5% vs 50.7%, P<0.05). At the end of follow-up, the mortality rate of aCL-positive group was 13.7%, and the mortality rate of aCL-negative group was 14.9% and there was no significant difference in mortality (P>0.05). Kaplan-Meier survival analysis showed that the 1-year, 5-year, and 10-year survival rates of aCL-positive group were 94.5%, 89.0%, and 82.9%, respectively, and there was no significant difference compared with aCL-negative group(P=0.776). The main causes of death in aCL-positive group were lupus encephalopathy (6 cases, 30.0%), renal failure (5 cases, 25.0%), heart failure (4 cases, 20.0%) and infection (3 cases, 15%). The main causes of death in aCL-negative group were infection (21 cases, 40.4%), lupus encephalopathy (11 cases, 21.2%) and heart failure (5 cases, 9.6%) and renal failure (4 cases, 7.7%). Conclusion SLE patients with aCL represent a high propotion in anemia, decreased C3, positive antinuclear antibody, positive anti-dsDNA antibody. There was no significant difference in disease activity and significant organ involvement between two groups. More SLE patients with aCL were treated with cyclophosphamide, and there was no significant difference in survival status between SLE patients with and without aCL during long-term follow-up.
RESUMO
Despite the improved survival rate among systemic lupus erythematosus (SLE) patients, there are many factors associated with the mortality of SLE. In the current study, death-related factors of patients associated with course of disease were surveyed. Retrospective study was used. Mortalities among these three groups (group A, B and C, the course of disease was ≤ 5 years, 5-10 years and > 10 years, respectively) were calculated and compared. Various factors related to mortality were analyzed. Male SLE patients died relatively more than female patients. The total mortality was 8.5 %. The mortalities were significant difference in group A, B and C which were 9.4, 4.8 and 8.9 %, respectively. The mortalities of group A and group C were significantly higher than that of group B, but there was no significant difference between mortalities of group A and group C. The most common death-related factor was infection, followed by involved disorders in renal, brain, multisystem, heart, etc. The mortalities resulted from neuropsychiatric systemic lupus erythematosus (NPSLE), pulmonary infection, involved digestive system and hematological system were significantly different between three groups. There was no difference between mortalities of group A and group C associated with pulmonary infection and NPSLE. Patients in group C died more than in group A from involved renal, heart, multisystem, etc, while group A had more patients than group C who died of pulmonary infection, involved hematological system. In conclusion, Male SLE patients have worse outcome than female patients. Infection and active SLE are not only contributors to the death of early stage patients, but also to that of later stage patients.

In this study, we used traditional morphological and molecular identification methods to preliminarily identify two strains of dermatophytes. The two strains were observed under the microscope. And then the dermatophytes were cultured on Sabouraud's dextrose agar (SDA). The 18S rRNA regions of the two dermatophyte strains were amplified by polymerase chain reaction (PCR), and the PCR products were sequenced and compared with GenBank data. BLAST tools and DNAMAN software were used to analyze the sequences. To further determine highly homologous sequences, a phylogenetic tree was constructed using the Neighbor-Joining method. The two strains of dermatophytes were identified by traditional morphological identification as Epidermophyton floccosum and Microsporum ferrugineum. The 18S rRNA sequence analyses showed high similarities to Cladosporium cladosporioides isolate C115LM-UFPR and Ascomycete sp. LB68A1A2. Epidermophyton and Cladosporium belong to dermatophyte, while Microsporum ferrugineum and Ascomycete belong to microsporum. The two novel strains of dermatophytes were therefore identified as Cladosporium cladosporioides isolate C115LM-UFPR (JN650537, Cladosporium) and Ascomycete sp. LB68A1A2 (AY770409, Ascomycete sp).

RESUMO
ObjectiveTo investigate the clinical features of systemic lupus erythematosus (SLE) patients with fever and find out the related factors.MethodsData was collected by the same methods in the past ten years in fifteen hospitals in Jiangsu province and then the data wereretrospectively analyzed.The potentially possible risk factors of fever in SLE were selected and then analyzed by chi-square test,Wilcoxon rank sum test and Logistic regression analysis.ResultsAll 1762 patients were investigated.Seven hundred and twenty-nine had active fever.Age at hospitalization,initially treated patients,photosensitivity,serositis,nervous system involvement,generalized lymphadenopathy/hepatosplenomegaly,white blood cell count (WBC),haemoglobin (HB),erythrocyte sedimentation rate (ESR),C-reaction protein (CRP),alanine aminotransferase(ALT),albumin(ALB),serum creatinine (Scr),complement C3,anti-dsDNA antibodies positive rate,anti-Sm antibodies positive rate,SLEDAI score and past therapies were factors associatedwith SLE fever.Logistic regression analysis showed that abnormal WBC count (OR=1.396,95%CI 1.114-1.711,P=0.004),CRP(OR=1.005,95%CI 1.002-1.009,P=0.002),ALT(OR=1.003,95%CI 1.001-1.005,P=0.005),Scr (OR=0.997,95%CI0.995-0.999,P=0.007),HB (OR=0.986,95%CI 0.981-0.992,P=0.000),age (OR =0.984,95% CI 0.974-0.993,P=0.001 ) and past usage of cyclophosphamide (CTX) (OR =0.557,95%CI 0.382-0.813,P=0.002) were correlated with SLE fever.ConclusionFever is one of the most common clinical manifestations of SLE patients.Leucopenia,elevated CRP levels,liver function abnormalities,anemia,younger age are risk factors for SLE fever,while renal impairment and past usage of CTX are protective factors.

Objective To study the genome DNA methylation in rheumatoid arthirits(RA)and the re- lated factors of DNA methylation.Methods Twenty-first cases with RA and 20 controls were recruited to par- ticipate the study.Plasma Hcy,SAM,SAH,the MTHFR gene C677T polymorphism and the expression of LFA-1 in CD4~+T cells was measured in all patients and controls.Results①The SAM levels were lower sig- nificantly in RA groups than in controls.The SAH levels were higher significantly in RA groups than in con- trols.②There was significant inverse correlation between plasma Hcy level and SAM level(r=-0.932,P<0.01). There was significant positive correlation between plasma Hcy level and SAH level(r=0.924,P<0.01).③The expression of LFA-1 in CD4~+T cells was higher significantly in RA groups than in controls.There was a signif- icant positive correlation between LFA-1 expression level and Hcy level(r=0.557,P<0.01),a significant in- verse correlation between LFA-1 expression level and SAM level(r=-0.651,P<0.01).④The MTHFR gene mu- tation lead to dramatically increase of Hcy,SAH level and the expression of LFA-1 level in CD4~+T cells and genome DNA hypomethylation.Conclusion①Hypomethylation of genome DNA is found in most RA pa- tients.②The factors associated with genome DNA hypomethylation include MTHFR gene mutation and hyper- homocysteinemia.③The expression of LFA-1 in CD4~+ T cells is higer in RA groups than in controls,which re- lates to the DNA methylation level and the MTHFR gene C677T polymorphism.
