Objective To detect anti-clinically amyopathic dermatomyositis (CADM)-140 antibody in patients with dermatomyositis (DM) or CADM,and to estimate its clinical correlation.Methods Serum samples were collected from 22 patients with DM,16 patients with CADM,46 patients with other connective tissue diseases complicated by interstitial lung disease(including 8 cases of polymyositis,15 cases of systemic lupus erythematosus,5 cases of systemic sclerosis,6 cases of Sj(o)gren syndrome,6 cases of mixed connective tissue disease,6 cases of idiopathic pulmonary fibrosis),and 5 normal human controls.Enzyme-linked immunosorbent assay (ELISA) was performed with the recombinant melanoma differentiation-associated gene 5(rMDA)as a substrate to measure the anti-CADM-140 antibody in these serum samples.Clinical manifestations were compared between patients with anti-CADM-140 antibody and those without.Results The anti-CADM-140antibody was found in 43.8% (7/16) of patients with CADM and 9.1%(2/22) of patients with DM(P<0.05),but absent in the patients with other connective tissue diseases and in the normal human controls.A significant incroase was observed in anti-CADM-140 antibody-positive patients with DM/CADM in the incidence of cutaneous ulceration and necrosis,interstitial lung disease and rapidly progressive interstitial lung disease (8/9 vs.6.9%,P<0.01;9/9 vs.48.3%,P<0.01;5/9 vs.0,P<0.05),serum lactate dehydrogenase level(328.3±104.2 vs 241.1±100.3 IU/L P<0.05),erythrocyte sedimentation rate(40.8±23.1 vs.22.5±16.8 mm/1 h,P<0.05),high resolution computed tomography score(122.9±54.8 vs.70.0±59.8,P<0.05)compared with anti-CADM-140 antibody-negative patients with DM/CADM.The ereatine kinase level was significantly lower(156.3±260.8 vs.1806.2±3737.1 IU/L P<0.05)in anti-CADM-140 antibody-positive patients with DM/CADM than in anti-CADM-140 antibody-negative patients with DM/CADM,while no significant difference was noted in the positivity rate of antinuclear antibodies or incidence of malignancies between the antibody-positive and-negative patients with DM/CADM.Conclusions Anti-CADM.140 antibody not only is useful for the diagnosis of interstitial lung disease in patients with DM/CADM,but also may serve as a serum marker for rapidly progressive interstitial lung disease.Monitoring of serum anti-CADM-140 antibody might help to predict the progression of interstitial lung disease in patients with DM/CADM.

Objective To evaluate the significance of CT assessment for extraarticular anatomy in treatment of displaced intraarticular calcaneal fractures.Methods(1)Measurement of normal calcaneum 40 pieces of adult calcaneum specimen were measured,items of measurement included height of culmination of posterior facet and tuberosity,width of posterior edge of sustentaculum and tuberosity.(2)CT measurement of calcaneum.Transverse(axial)and coronal CT scanning were obtained from 20 feet with displaced intraarticular calcaneal and 20 normal feet as control.Following items were measured in CT scanning:the height of culmination of posterior facet and tuberosity,the coronal talocalcaneal angle,in coronal scanning,the width of posterior edge of sustentaculum and tuberosity,the axial calcaneocuboid angle,in axial scanning.Results(1)Measurement of height of calcaneum height of culmination of posterior facet and tuberosity of calcaneal specimen were(43.07?2.85)mm and(44.69?3.67)mm respectively,and these two items from CT scanning of normal feet were(42.84?1.66)mm,(43.40? 3.01)nun,and from CT scanning of feet with calcaneal fractures were(34.76?3.24)mm,(40.41? 3.69)mm.There was a statistically significant different between these two items for normal calcaneal specimen and for CT scanning of feet with ealcaneal fractures(P

Objective To investigate the serum IL-33 level and its association with TH1,TH2,TH17 and Treg cells in patients with unexplained recurrent spontaneous abortion(URSA).Methods Forty-six URSA patients and 40 healthy controls were enrolled.The proportions of TH1,TH2,TH17 and Treg cells in peripheral blood samples were determined by flow cytometry,and serum IL-33 levels by ELISA.Results The levels of serum IL-33 in URSA patients were significantly lower than that in healthy controls.The proportions of TH2 and Treg cells in URSA patients were significantly lower than that in healthy controls (P ＜ 0.05),while the proportions of TH 1 and TH 17 cells in URSA patients were significantly higher than that in healthy controls.Serum IL-33 levels were negatively correlated with the proportions of TH 1 and TH17 cells,and positively with that of TH2 cells,while no correlation with Treg cells.Conclusion Serum IL-33 levels decrease significantly in URSA patients,and are correlated with the proportions of TH1,TH2 and TH17 cells,indicating that IL-33 may be associated with TH1,TH2 and TH17 cells in URSA patients.

OBJECTIVECongenital nephrotic syndrome (CNS) is defined as heavy proteinuria or nephrotic syndrome occurring before 3 months of age. It is characterized by early onset, resistance to steroid therapy and progressing to end-stage renal disease (ESRD). In recent years, several genes associated with CNS have been identified, such as NPHS1, NPHS2 and WT1. The mutations of these genes have been identified in the patients with CNS in Finland, other European countries, North Africa, North America, and Asia, respectively. However, the investigation of the above genes has not been performed in Chinese CNS patients. In this study, NPHS1 mutations in a Chinese family with CNS were detected and analyzed.

METHODSThere were two CNS patients in the investigated family. The proband, a 45-day-old boy, was born at fullterm and weighed 2700 g at birth. The placenta weighed 450 g. At the age of 10 days, generalized edema, proteinuria, hypoproteinemia, and hypoalbuminemia were found without renal insufficiency. The proband's sister, with the same phenotype and normal renal function, underwent renal biopsy at 5 years of age. Their parents and elder half-sister all had normal phenotypes. Genomic DNA samples were extracted from peripheral bloods of the proband, his family members and 50 unrelated, normal individuals. All 29 exons and exon-intron boundaries of NPHS1 were detected in the proband by polymerase chain reaction (PCR), direct DNA sequencing, and restriction enzyme analysis.

RESULTSThree heterozygous mutations of NPHS1, namely, G928A (D310N), 1893-1900del 8 (CGAAACCG), and G2869C (V957L) were identified in the proband. These mutations involved exons 8, 14, and 21. The same genotype was found in the proband's sister who had the same phenotype, but was not detected in proband's elder half-sister who had normal phenotype. Fifty normal individuals had no these mutations. The proband's mother with normal urinalysis had G928A (D310N) heterozygous mutation, and the father with normal urinalysis had two heterozygous mutations of 1893-1900del 8 (CGAAACCG) and G2869C (V957L). At the same time, three types of single nucleotide polymorphisms (SNPs), E117K (rs3814995), S1105S (rs2071327), and IVS27+45c > t, were confirmed in the proband. Another variant, IVS8+68 a > g had also been found.

CONCLUSIONThis is the first report about NPHS1 mutations in Chinese CNS kindred. These three heterozygous mutations of NPHS1 are novel genetic defects of CNS, which have not been described before.

Estrogen receptors (ERs) are members of nuclear receptors and related to several diseases such as cancer, inflammation and osteoporosis. ERs have two forms, ERα and ERβ, which have different functions and organism distributions. Compounds selectively targeting ERβ can regulate important physiological functions and avoid the side effects caused by targeting ERα. Therefore, selective ERβ ligands have received considerable research interest in recent years. In this article, different kinds of selective ERβ ligands were summarized and their structure-activity relationships were also analyzed.
