Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.

Background Hyperuricemia is frequently present in patients with heart failure. Many pathological conditions, such as tissue ischemia, renal function impairment, cardiac function impairment, metabolic syndrome, and inflammatory status, may impact uric acid (UA) metabolism. This study was to assess their potential relations to UA metabolism in heart failure. Methods We retrospectively assessed clinical characteristics, echocardiological, renal, metabolic and inflammatory variables selected on the basis of previous evidence of their involvement in cardiovascular diseases and UA metabolism in a large cohort of randomly selected adults with congestive heart failure (n = 553). By clustering of indices, those variables were explored using factor analysis. Results In factor analysis, serum uric acid (SUA) formed part of a principal cluster of renal functional variables which included serum creatinine (SCr) and blood urea nitrogen (BUN). Univariate correlation coefficients between variables of patients with congestive heart failure showed that the strongest correlations for SUA were with BUN (r = 0.48, P < 0.001) and SCr (r = 0.47, P < 0.001). Conclusions There was an inverse relationship between SUA levels and measures of renal function in patients with congestive heart failure. The strong correlation between SUA and SCr and BUN levels suggests that elevated SUA concentrations reflect an impairment of renal function in heart failure.

OBJECTIVETo analyze the clinical characteristics of plastic bronchitis associated with 2009 influenza A virus (H1N1) infection.

METHODA retrospective investigation of the clinical manifestation, bronchoscopy, and the histology of the cast, clinical course and outcome of 8 children with plastic bronchitis associated with influenza A virus (H1N1) infection during winter of 2009 and 2010 was performed.

RESULTAll 8 cases were boys, the range of age was 3 to 6 years. Five cases occurred in 2009 winter, accounting for 3.3% (5/150) of hospitalized children with influenza A (H1N1) infection; 3 cases occurred in 2010 winter, accounting for 15.8% (3/19) of hospitalized children with influenza A (H1N1) infection. Two patients had an underlying chronic disease, 1 had asthma, and the other had allergic rhinitis and atopic dermatitis. All the 8 cases had fever, cough and sputum; 2 had wheezing; 5 had respiratory distress. All 8 cases were diagnosed as influenza A virus (H1N1) infection complicated with pneumonia, of whom 5 patients had atelectasis, 2 had pneumothorax, 1 had pneumomediastinum, 1 had parapneumonic effusion, 2 patients were suspected of foreign body aspiration. Seven cases were admitted to an ICU, 5 patients developed respiratory failure, and 3 patients required mechanical ventilation. Flexible bronchoscopy and bronchial lavage was performed in all cases and showed bronchial cast. Histological examination of the bronchial cast revealed a fibrinous material containing large quantity of eosinophils, neutrophils, and lymphocytes in 7 patients, fibrinous material and necrotic material without inflammatory cells in 1 patient. After the bronchial cast was removed, all patients were improved greatly, no patients died.

CONCLUSIONPlastic bronchitis is a life-threatening complication associated with 2009 influenza A (H1N1) virus infection in children. In children with rapid and progressive respiratory distress with lung atelectasis or consolidation on chest radiograph, plastic bronchitis should be considered. Bronchoscopic extraction of casts should be carried out early.

This study was purposed to investigate the acute myeloid leukemia with complex karyotype t(2;21;8)(p12;q22;q22) (AML-M(2)) by using morphologic, immunologic, cytogenetic and molecular biologic classification technique (MICM) and to analyze the MICM characteristics of AML-M(2) and their diagnostic significance. The FAB typing of bone marrow cells (BMCs) was performed by Wright-Giemsa staining and histochemical staining of BM smears; the immunophenotype of leukemic cells was detected by flow cytometry; the karyotypes of chromosome samples prepared by short-term (48 hours) conventional culture of fresh BMCs were analyzed by RHG banding technique; the FISH signaling in mitotic metaphase was determined by dual color and dual fusion AML/ETO probe and chromosome painting probe, and was compared with results of conventional cytogenetic assay; the AML/ETO fusion transcripts were detected by nested RT-PCR. The results indicated that the bone marrow smears of case 1 showed extremely hyperplasia with myeloblasts in which a ratio of eosinophilic granulocytes and monocytes increased. Case 2 accorded with AML-M(2b) in which abnormal increase of myelocytes mainly appeared. The complex karyotype t(2;21;8)(p12;q22;q22) was detected by cytogenetic analysis combined with FISH in both two cases and AML1/ETO fusion transcripts were found by RT-PCR as well. The immunophenotype assay showed high co-expression of CD34 and HLA-DR accompanied with CD19 and CD56 expressions. It is concluded that application of MICM has an important significance for correct diagnostic typing of AML-M2 with complex karyotype variant of t(8; 21)(p12;q22;q22).

The purpose of this study was to detect the expression of RAGE-1 transcript in the bone marrow mononuclear cells (BMMNC) from patients with acute myeloid leukemia (AML) and to investigate the relationship of RAGE-1 expression level with clinical variables. The expression level of RAGE-1 gene in BMMNC from 94 newly diagnosed AML patients was measured using RQ-PCR. The relationship between RAGE-1 expression level and clinical parameters (age, sex, blood cell counts, diagnosis and prognosis) was investigated, and the levels of RAGE-1 expression were compared in patients before and after treatment. The results showed that overexpression of RAGE-1 transcript was found in 28% (26/94) AML patients (1.34 - 16.34, median 3.07). No significant difference was observed in sex, age, blood parameters and FAB subtypes between the groups with and without RAGE-1 overexpression. There was also no significant difference in the frequency of RAGE-1 overexpression among different cytogenetic risk groups and among the patients with different types of karyotypes. The level of RAGE-1 transcript significantly decreased in those patients obtained complete remission after treatment. The overall survival of AML patients with RAGE-1 overexpression was similar as that in those without RAGE-1 overexpression. It is concluded that RAGE-1 overexpression is a common event in AML, but has no impact on the prognosis of patients.
