Objective To explore relationship between antinucleosome antibody and desease activity of systemic lupus erythematosus(SLE). Methods Serum antinucleosome antibodies were measured by ELISA in the 88 patients with SLE. The relationship among antinucleosome antibodies, disease activity ( evaluated using SLEDAI), anti-dsDNA antibody and complements was analyzed. Results Antinucleosome antibody was positive in 70 patients with SLE (79.5%). There were correlations between the antinucleosome antibody and SLE disease activity, anti-dsDNA antibody, complement C3, erythrocyte sedimentation rate. Conclusion Antinucleosome antibody is a relatively sensitive marker in diagnosing SLE and evaluating SLE disease activity.

Objective To investigate the relationship between wheezing and serum levels of 25-hydroxyvitamin D3.Methods 130 children with lower respiratory tract infection were selected as the subjects, the children with wheezing in group A([Abstract] Objective To investigate the relationship between wheezing and serum levels of 25-hydroxyvitamin D3.Methods 130 children with lower respiratory tract infection were selected as the subjects, the children with wheezing in group A(n=70),normal pneumonia (no wheezing) were group B(n=60); The healthy children who were examined in the hospital at the same period were selected as the control group (n=60). The serum levels of 25-hydroxyvitamin D3 were measured by ELISA in the control and hospitalized children. The pathogens and allergens of the two groups were also detected. Results The levels of serum 25-hydroxyvitamin D3 in group A and group B were (56.92±16.88) nmol/L, (70.68±21.96) nmol/L, respectively, which was significantly lower than that in control group (82.69±17.63) nmol/L, ( t=8.50, 3.30,P=0.00,0.00); compared with group A( t=3.85, P=0.00). The positive rate of group A was 65.71%, which was significantly higher than that of group B (35.00%, χ2=12.20,P=0.00). The positive rate of group A was 30.00% compared with the control group (35.00%, χ2=0.36,P=0.54). The serum level of 25-hydroxyvitamin D3 was 75.57% in group A, which was significantly higher than that in group B (60.00%,χ2=14.21, P=0.00). The positive rate of virus detection was 57.14% in 98 children with serum 25-hydroxy vitamin D3 level<75 nmol/L, which was significantly higher than that in serum 25-hydroxy vitamin D3 level≥75 nmol/L(18.75%, χ2=14.25, P=0.00). The positive rate of allergens in serum 25-hydroxy vitamin D3 level <75 nmol/L was 35.71%, which was significantly higher than that in serum 25-hydroxy vitamin D3 level≥75 nmol/L(21.88%, χ2=2.11, P=0.14). Conclusion The main risk factor for children with wheezing is viral infection, while the low level of serum 25-hydroxy vitamin D3 in children increases the risk of viral infection, resulting in increased risk of wheezing in patients,so the clinical can occur through the detection of serum 25- hydroxyvitamin D3 levels to predict and intervention for children with wheezing.

Objective:To analyze the features of the connective tissue associated interstitial lung disease (CTD-ILD) by high resolution computed tomography (HRCT).Methods:A total of 127 patients with CTD-ILD,who were diagnosed by clinic laboratory examination and pathology in Xiangya Hospital of Central South University form September 2013 to September 2015,were enrolled for this study.Their lung features of HRCT imaging were retrospectively analyzed.Results:The classifications for 127 patients were as follows:36 cases of rheumatoid arthritis (28.3%),34 cases of dermatomyositis and polymyositis (26.8%),31 cases of systemic sclerosis (24.4%),18 cases of Sj(o)gren syndrome (14.2%),7 cases of mixed connective tissue disease (5.5%),and 1 cases of systemic lupus erythematosus (0.8%).According to the features of HRCT imaging,the patients were divided as follows:77 cases (60.6%) ofnonspecific interstitial pneumonia (NSIP),46 cases (36.2%) of usual interstitial pneumonia (UIP),2 cases (1.6%) of lymphocytic interstitial pneumonia (LIP),1 case (0.8%) of cryptogenic interstitial pneumonia (COP),and 1 case (0.8%) of acute interstitial pneumonia (AIP).The HRCT findings for 36 cases of rheumatoid arthritis associated interstitial lung disease were UIP (24 cases,66.7%) and NSIP (12 cases,33.3%);the HRCT findings for 34 cases of dermatomyositis and polymyositis associated interstitial lung disease were NSIP (32 cases,94.1%),UIP (1 case,2.9%) and COP (1 case,2.9%);the HRCT findings for 31 cases of systemic sclerosis associated interstitial lung disease were NSIP (21 cases,67.8%),UIP.(9 cases,29%),LIP(1 case,3.2%);the HRCT findings for 18 cases of Sj(o)gren syndrome associated interstitial lung disease were NSIP (9 cases,50.0%),UIP (8 cases,44.4%),LIP (1 case,5.6%);the HRCT findings for 7 cases of mixed connective tissue disease associated interstitial lung disease were UIP (4 cases,57.1%),NSIP (3 cases,42.9%).SLE-ILD was rare,with only 1 case of AIP.Conclusion:Different types of CTD-ILD patients display relatively unique manifestation of HRCT.

Objective To investigate the clinical significance of anti-β2 glycoprotein Ⅰ(anti-β2GP Ⅰ)antibodies in patients with systemic lupus erythematosus(SLE)and to assess their association with lupus thrombocytopenia.Methods Anti-β2GP Ⅰ antibodies were tested in 108 SLE patients(including 37thrombocytopenia patients),30 patients with rheumatoid arthritis(RA)and 30 healthy individuals by enzyme-linked immunosorbent assay(ELISA).The clinical features and laboratory findings were collected,and the associations of anti-β2GP Ⅰ antibody with laboratory findings and disease activity were analyzed.Results Sensitivities of anti-β2GP Ⅰ antibody were 19.44%(21/108)in SLE and 10%(3/30)in RA,respectively.The specificity of anti-β2GP Ⅰ antibody was 95.0% in SLE.The anti-β2GP Ⅰ antibody titers of the SLE group were significantly higher than normal group(P ＜ 0.05).There was no significant correlation between anti-β2GP Ⅰ antibodies and thrombocytopenia(r =-0.028,P ＞0.05).Anti-β2GP Ⅰ antibody was positively correlated to anticardiolipin antibody(r = 0.566,P ＜ 0.01).No associations were found between anti-β2GP Ⅰ antibody and other clinical and laboratory features.There was no statistical correlation between the level of anti-β2GP Ⅰ antibody and SLEDAI scores.Conclusions Anti-β2GP Ⅰ antibody had high specificity in SLE.There was no significant correlation between anti-β2GP Ⅰ antibodies and lupus thrombocytopenia.

Objective To analyze the epidemiological characteristics of malaria in Nanjing City,so as to provide the evi?dence for further formulating and adjusting the malaria prevention and control strategy. Methods The data of malaria situation, malaria cases and epidemiological investigations were collected from the Internet Reporting System in Nanjing City from 2010 to 2015 and analyzed statistically. Results A total of 137 confirmed malaria cases were reported in Nanjing City from 2010 to 2015,including 102 falciparum malaria cases(74.45%),33 vivax malaria cases(24.09%),one ovale malaria case(0.73%) and one quartan malaria case(0.73%). Among the 137 malaria cases,126 cases(91.97%)were imported from foreign coun?tries,2 cases(1.46%)were infected locally,and nine cases(6.57%)were imported from other provinces in China. Among the 126 overseas imported cases,117 cases were imported from African countries and 9 from Asian countries. These malaria cases were majorly young men working as migrant workers,laborers and technical persons. About 19.30%of the cases went to hospital on onset day,and 55.65%were confirmed by medical institutions as malaria in the same day. The majority of diagnosis institu?tions were municipal hospitals(74.45%). Conclusions The number of malaria cases in Nanjing City is declining year by year. The local infections are eliminating gradually. However,the situation of imported malaria from overseas is still serious. There?fore,the surveillance work and health education still should be strengthened,so as to reduce the risk of imported malaria.

Objective To determine the safety, pregnancy outcome and the affect on neonates in pregnant patients with systemic lupus erythematosus(SLE).Methods Sixty-two pregnant patients with SLE were evaluated retrospectively from 1999 to 2009 in our hospital. These patients were divided into two groups:selective pregnancy group and nonselective pregnancy group. The pregnancy outcomes, fetal outcomes, and lupus activity during pregnancy were compared between the two groups. The children of the SLE patients were followed up. Results There were 43 patients in the selective pregnancies group and 19 patients in nonselective pregnancies group. In the selective pregnancies group, lupus flare occurred in 10 pregnancies(23%), 35(81%)had a live birth, 7 had low birth weight infants and 7 had premature delivery; however, in the nonselective pregnancies group, lupus flare occurred in 16 pregnancies(84%), 13(68%) had abortion,6 had a live birth, but all neonates were low birth weight infants. The rates of lupus flare and pregnancy loss in the nonselective pregnancy group were higher than those of the selective pregnancy group(P＜0.05). None of the 22 children had SLE during the follow-up period. Conclusion Both selective and nonselective pregnancy may adversely affectmaternal and fetal outcomes, but patients with selective pregnancy have better outcomes either in lupus flare or maternal and fetal outcomes compared with those of the nonselective pregnancy.

Systemic sclerosis (SSc) is a multisystem fibrotic and autoimmune disease. Both genetic and epigenetic elements mediate SSc pathophysiology. This review summarizes the role of one epigenetic element, known as microRNAs (miRNAs), involved in different signaling pathways of SSc pathogenesis. The expression of key components in transforming growth factor-b (TGF-b) signaling pathway has been found to be regulated by miRNAs both upstream and downstream of TGF-b. We are specifically interested in the pathway components upstream of TGF-b, while miRNAs in other signaling pathways have not been extensively studied. The emerging role of miRNAs in vasculopathy of SSc suggests a promising new direction for future investigation. Elu-cidation of the regulatory role of miRNAs in the expression of signaling factors may facilitate the discovery of novel biomarkers in SSc and improve the understanding and treatment of this disease.

Objective To understand the diagnostic values of procalcitonin (PCT),C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),white blood cell (WBC) and neutmphilic granulocyte ratio (NE％) in distinguishing concurrent bacterial infection from idiopathic inflammatory myopathy (ⅡM).Methods Clinical data and laboratory examinations of 118 ⅡM patients were collected.The ⅡM patients were assigned to the bacterial infection group (n=66) or the non-infection group (n=52).The levels of PCT,CRP,ESR,WBC and NE％ were compared by the Mann-Whitney U tests between the two groups and receiver operating characteristic curves were generated in order to evaluate the diagnostic value.Results The levels of PCT (0.06 ng/ml,0.03 ng/ml,U=2.637,P＜0.01);CRP (15.80 mg/L,4.40 mg/L,U=5.944,P＜0.01);ESR (43.50 mm/1 h,27.00 mm/1 h,U=2.266,P＜0.05);WBC (9.85×109/L,7.70×109/L,U=2.675,P＜0.01) and NE％ (80.70％,75.75％,U=2.344,P＜0.01) were significantly higher in the ⅡM patient group with concurrent infection than in the noninfection ⅡM patient group.CRP showed the highest diagnostic value with sensitivity,specificity,positive predictive value and negative predictive value of 72.7％,82.7％,84.2％ and 70.5％,respectively.Conclusion The inflammatory biomarkers PCT,CRP,ESR,WBC and NE％ offer diagnostic accuracy in detecting bacterial infection in ⅡM patients.Particularly,CRP is the most sensitive and specific biomarker indetecting bacterial infection in ⅡM patients.

OBJECTIVE: To improve the understanding of lupus cystitis. METHODS: Clinical manifestations, laboratory Results , and image information of 2 cases of lupus cystitis were analysed retrospectively, and another 6 cases in the literature were reviewed. RESULTS: Two patients were female. The urinary symptoms followed the gastrointestinal symptoms. Ureterectasia and hydronephrosis were detected in both patients, and intestinal pseudo-obstruction was detected in one patient. In the 6 cases from the literature, ureterectasia and hydronephrosis were detected in all patients, and intestinal pseudo-obstruction was detected in 4. CONCLUSION The possibility of lupus cystitis should be considered when lupus patients complain of urinary or bowel symptoms. Glucocorticoid and immunodepressant are effective for lupus cystitis.
