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.

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 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.

OBJECTIVE:To analyze the factors in the causation of cefradine-induced hematuria.METHODS:The material in CHINESE BIBLIOGRAPHIC DATA BASE OF BIOLOGY & MEDICINE(from 1980 to February 2001)and PHARMACEUTICAL ABSTRACTS(1990～2000)was reviewed and the data were analysed on patients'age and sex,route of drug administration,beginning of hematuria,prognosis and time of recovery.RESULTS:18 reports on cefradine-induced hematuria(108 cases) were found,which indicated that hematuria was mainly associated with renal hypoplasia in childhood and intravenous administration of cefradine.CONCLUSION:Intravenous administration of cefradine in children should be very careful.

Objective: To observe the clinical effect of electroacupuncture (EA) combined with tuina on acute lumbar sprain and lumbar muscle tone before and after treatment. ＜br> Methods: A total of 130 acute lumbar sprain cases were randomly allocated into an observation group and a control group, 65 in each group. Cases in the observation group were treated with EA combined with tuina, whereas cases in the control group were treated with Diclofenac Sodium Dual Release Enteric-coated capsules. The muscle tones in two groups were tested before and after treatment. ＜br> Results: The recovery rate and overall response rate in the observation group were 66.2% and 93.8% respectively, versus 56.9% and 87.7% in the control group, showing no between-group statistical significances (P>0.05). After treatment, the force-displacement area under curve (AUC) in both groups showed a significance difference (P＜0.05). ＜br> Conclusion: Both EA combined with tuina and aforementioned oral medication have remarkable effects for acute lumbar sprain, and the former can better improve the lumbar muscle tone in patients with acute lumbar sprain.

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.
