Acute myeloid leukemia (AML) is a heterogenous disorder disease, about 40 %-49 % of the adult AML and 25 % of children had normal karyotype AML, and usually categorized as an intermediaterisk group, but for acquired genetic change, such as mutations of FLT3, NPM1, CEBPα, MLL, and KIT as well as alterations in expression levels of BAALC, MN1, ERG, and EVI1, leading to significant heterogeneity for the prognosis of this group. In this report, prognostic genetic findings in normal karyotypical AML and discuss their clinical implications was reviewed.

Objective To explore the diagnostic value of secretory phospholipase A2 (sPLA2) and lysophosphatic acid (LPA) for ovarian cancer and evaluate the correlation of sPLA2 activity and LPA level to the prognosis in the patients with ovarian cancer.Methods ~3H oleic acid labeled E. coli membrane and spectrophotometry were used to detect the original and recurrent ovarian cancer. The motive observation between sPLA2 activity and LPA level was done.At the same time, The sensitivity and specificity for the diagnosis of ovarian cancer were analyzed.Results Comparing the original ovarian cancer group with the ovarian benign tumor group, the difference between sPLA2 activity (24.47 ?5.64 U/L,4.94 ?1.86 U/L) and LPA levelc(6.35 ?2.32 ?mol/L,1.92 ?0.75 ?mol/L) were significantly (P

From the beginning of the 20th century, Alois Alzheimer, a German doctor, discovered Alzheimer′s disease, so far, the isease-related research has been the focus of researchers all over the world. From Alzheimer's disease to mild cognitive impairment, then to subjective cognitive impairment, the attention phase of the disease is also being advanced. Subjective cognitive impairment, as a stage earlier than mild cognitive impairment, has important implications for the early diagnosis and intervention of Alzheimer′s disease.This article will summarize the research progress of conception and screening instruments for subjective cognitive impairment at home and abroad.

Objective:To evaluate the role of IL-23 in the production of IFN-?, cell subsets and regulation by human peripheral blood mononuclear cells(PBMCs).Methods:PBMCs were isolated from normal human peripheral blood and cultured with IL-23 in different culture conditions. The level of IFN-? in the culture supernatants was examined by ELISA. The subsets and frequency of IFN-?-producing cells were examined at a single cell level by flow cytometry.Results:IL-23 could directly induce IFN-? production by PBMCs and have synergistic effect with IL-2 on the induction of IFN-? production in a dose dependent manner. The data from Flow cytometric analysis indicated that IL-23 could induce IFN-? expression by CD3~-CD56~+NK cells but not CD3~+CD4~+ and CD8~+T cells. It is noted that IL-23 predominantly induced IFN-? expression by NK cells with high expression of CD56 molecules. Addition of Th2 cytokines or anti-IL-12R?1 mAbs resulted in the inhibition of IL-23-inducing IFN-? production.Conclusion:IL-23 can directly induce IFN-? production by PBMCs. The induction of IFN-? induced by IL-23 can be suppressed by Th2 cytokines and anti-IL-12R?1 mAbs. The data indicated that Th2 cytokines and anti-IL-12R?1 mAbs might have the potential application for the treatment of IL-23-mediated autoimmune diseases.

Purpose To investigate the expression of TAZ and β-catenin in colorectal carcinoma and to analyze their correlation with the clinical pathological features of colorectal carcinoma. Methods The immunohistochemical method was used to detect the expres-sion of TAZ and β-catenin in 168 colorectal carcinoma specimens and 30 normal colorectal mucosal specimens. Results The positive rate of TAZ expression was significantly higher in colorectal carcinoma than that in normal colorectal mucosal (P<0. 01). The ectopic expression ofβ-catenin was significantly higher in colorectal carcinoma than that in normal colorectal mucosa (P<0. 01). The expres-sion of TAZ was correlated with degree of differentiation, lymph node metastasis, invasion depth and TNM stages (P<0. 05), and that of β-catenin was correlated with lymph node metastasis, invasion depth and TNM stages (P<0. 05). The positive expression of TAZ and the ectopic expression of β-catenin were significantly related to the 5-years survival rate ( P<0. 05 ) . The expression of TAZ was significantly positively correlated with the ectopic expression of β-catenin ( P<0. 01 ) . Conclusion Up-regulated expression of TAZ and ectopic expression of β-catenin may be synergistically involved in the occurrence, invasion and metastasis of colorectal carcinoma.

Objective To explore the relationship between methylene tetrahydrofolate reductase (MTHFR) gene polymorphism and homocysteine (Hcy),and further to investigate their correlation to coronary heart disease (CHD) in females.Methods This study involved 29 premenopausal women with CHD,57 postmenopausal women with CHD,50 men with CHD and 46 postmenopausal women with non-CHD.All patients underwent coronary angiography.The patients' gender,age,history of hypertension,diabetes and smoking were recorded.The plasma Hcy level,blood lipids and MTHFR gene polymorphism were examined.Results The level of Hcy in postmenopausal women with CHD was (18.11±7.21)μmol/L,which was significantly higher than (15.01±6.53)μmol/L in premenopausal women with CHD,(12.98±5.46)μmol/L in postmenopausal women with non-CHD group and (14.32±6.01)μmol/L in men with CHD group (t=5.23,3.65,5.08,all P<0.05).The frequency of the MTHFR TT genotype in postmenopausal women with CHD was 28.1% which was significantly higher than postmenopausal women with non-CHD(17.4%)(χ2=5.13,P<0.05),but there was no statistically significant difference with the other two groups.The plasma Hcy level in patients with TT genotype was significantly higher than that with CT or CC genotype in all groups.Multivariate logistic regression analysis showed a significant positive correlation in Hcy and TT genotype.Multivariate logistic regression analysis showed that smoking,Hcy,hypertension and diabetes were independent risk factors for CHD.The odds ratios(OR) of Hcy for CHD was 2.601 (95% confidence interval,1.326 to 5.745).Conclusion Hcy may be an independent risk factor for CHD in females.MTHFR C677T genotype is significantly associated with hyperhomocysteinemia,and its mutation frequency increases significantly in patients with CHD,but MTHFR mutation is not related with the incidence of CHD.

Objective To investigate the clinical efficacy of Jiawei Guizhi Fuling Decoction combined with mifepristone on uterine fibroids and the changes of serum sex hormone levels in patients after treatment.MethodsForty-two patients were randomly divided into three groups: control group (42 cases) and control group (41 cases).The rats were treated with Guizhi Fuling Decoction plus mifepristone combination for three months.The control group was given only monotherapy with normal mifepristone tablets.The time of treatment was consistent with that of the study group.The levels of serum sex hormones were measured quantitatively before and after treatment.By comparing the therapeutic effect of the patients in different experimental groups and the levels of hormone Differences in evaluation between groups.ResultsThe total effective rate of 92.9% in the study group was significantly better than that in the control group (73.8%).The difference between the two groups was statistically significant (P<0.01).After treatment, the study group and the control group Uterine / tumor volume was significantly reduced, the difference was significantly different (P<0.01), compared between the two groups after treatment of uterine / tumor volume, the study group than the control group, the volume was significantly reduced, the difference was statistically significant (P<0.05).Serum levels of sex hormones: Serum levels of E2 and P were significantly lower in the study group than in the control group (P<0.05).Before and after treatment, the levels of serum E2 and P were lower in the two groups than before treatment (P<0.05).ConclusionJiawei Guizhi Fuling Decoction combined with mifepristone has a better effect on the treatment of uterine fibroids with mifepristone monotherapy, which significantly reduces the level of serum sex hormones and promotes the reduction of uterine / tumor volume after administration.It is worthy of promotion the combination of traditional Chinese and Western medicine conservative treatment of uterine fibroids means.
