Objective To observe the effect of Natural mountain spring on oxidative damage of aging mice . Methods Thirty male aging mice were randomly divided into experimental group ( drink Natural mountain spring ) and control group ( drink tap water ) according to the level of MDA .The serum in the two groups was taken for T-SOD activity and MDA content analysis after two months .Results The MDA content in experimental group decreased markedly than that in control group .Conclusion Natural mountain spring could alleviate oxidative damage by free radicals to extent .

AIM:To investigate the effects of angiotensin II ( Ang II) on the immune maturation and the oxi-dized low-density lipoprotein (Ox-LDL)-uptaking capacity of human monocyte-derived dendritic cells (DCs).METH-ODS:Human peripheral blood mononuclear cells were isolated by density gradient centrifugation , and the monocytes were purified by positive selection with anti-CD14 magnetic beads.After cultured with rhGM-CSF (100 μg/L) and rhIL-4 (50μg/L) for 5 d, the monocytes differentiated into immature DCs .On the 6th day of the culture, the cells were treated with various concentration levels of Ang II or pretreated with losartan .The immunophenotypic expression of HLA-DR and CD83 was analyzed by flow cytometry .The secretion levels of IL-12 and IFN-γin the culture supernatants were measured by ELISA.Furthermore, DCs were incubated with DiI-labelled Ox-LDL.The DiI-Ox-LDL-incorporated fraction was investiga-ted by flow cytometry .The mRNA expression of 3 scavenger receptors , scavenger receptor A ( SR-A) , CD36 and lectin-like oxidized low-density lipoprotein receptor 1 (LOX-1), was examined by real-time PCR.RESULTS: Ang II induced the maturation of human monocyte-derived DCs, stimulated the expression of CD83 and HLA-DR, and promoted the secre-tion of IL-12 and IFN-γ, which were suppressed by losartan .Furthermore, Ang II increased the Ox-LDL-uptaking capacity of DCs, which was partially reduced by losartan .The incubation of DCs with Ang II enhanced the mRNA expression of LOX-1 in a dose-dependent manner , which was reduced by losartan .However, the expression of SR-A and CD36 was not changed .CONCLUSION:Ang II promotes the immune maturation of human monocyte-derived DCs and increases the up-take of Ox-LDL probably through the up-regulation of LOX-1 expression.

Objective To investigate efficient diagnosis and treatment of 17α-hydroxylase (17OHD) deficiency by summarizing clinical characteristics of those patients.Methods From January 1983 to January 2010,48 cases with 17OHD in Peking Union Medical College Hospital were studied retrospectively.Results Among 48 patients with 17OHD,karyotype analysis showed,12 cases with 46,XX and 36 cases with 46,XY.The 46,XX karyotype and 46,XY karyotype with complete 17OHD had typical clinical presentation of amenorrhea [ 12/12,100% ( 36/36 ) ],no typical spontaneous puberty [ 12/12,13.9% (5/36) ],Hypertension [ 11/12,100% ( 36/36 ) ],hypokalemia [ K +:( 2.6 ± 0.7 ),( 2.8 ± 0.7 )mmol/L],hypergonadotropin [ follicle-stimulatinghormone ( FSH ):( 51 ± 35 ),( 79 ± 46 ) U/L,luteinizing hormone( LH ):( 27 ± 14 ),(49 ± 37 ) U/L ],impaired production of sex hormones [ testosterone(T):0.003,0.005 nmol/L; estradiol ( E2 ):26.86,10.64 pmol/L ],hyper-progesterone [ (P):( 32 ± 15 ),( 29 ± 23) nmol/L],impaired production of 17α-hydroxyprogesterone ( 17α-OHP ) [ ( 2.5 ± 1.1 ),( 2.4 ±1.7) nmol/L],ACTH hypersecreation (91.8,114.0 pmol/L).ACTH stimulating test did not elevated in 17α-OHP and cortisol.Conclusion When patients with elevated basal serum levels of progesterone higher than that of ovulation period in addition to clinical symptoms,examination about 17OHD should be warranted.

Objective:
To investigate the efficacy and safety of IA regimen which contains idarubicin (IDA) 8 mg/m2, 10 mg/m2 or 12 mg/m2 as induction chemotherapy for adult patients with de-novo acute myeloid leukemia (AML) .
Methods:
A total of 1 215 newly diagnosed adult AML patients, ranging from May 2011 to March 2015 in the First Affiliated Hospital of Soochow University and other 36 clinical blood centers in China were enrolled in the multicenter, single-blind, non-randomized, clinical controlled study. To compare the response rate of complete remission (CR) , adverse events between different dose idarubicin combined with cytarabine (100 mg/m2) as induction chemotherapy in newly diagnosed patients of adult AML.
Results:
Of 1 207 evaluable AML patients were assigned to this analysis of CR rate. The CR rates of IDA 8 mg/m2 group, IDA 10 mg/m2 group and IDA 12 mg/m2 group were 73.6% (215/292) , 84.1% (662/787) and 86.7% (111/128) , respectively (
