Leukemia is a kind of cloning disease from malignant hematopoietic stem cells. Its patho-genesis may have relationship with proliferation out of control,dysdiffreentiation and inhibition of apoptosis about leukemia cells. The study confirms that CD44 is expressed in leukemia cells,promoting the occurrence and development of leukemia through participation in cell adhension,proliferation,migration and invasion behavior. In vitro experiment shows that CD44 targeted therapies can effectively kill leukemia cells,and reduce the toxicity to normal tissue cells. Therefore,aiming at the design of the anticancer drugs targeted for CD44 is expected to be used in clinical treatment of leukemia.

Objective: To analyze the correlations of systolic blood pressure (SBP) with uric acid, blood lipid and blood glucose in adults, so as to provide the evidence for blood pressure management and early prevention of cardiovascular diseases. Methods: Based on the China Health and Nutrition Survey, data of participants in 2004 and 2009 was collected, including demographic characteristics, blood pressure, uric acid, blood lipid and blood glucose. Participants with SBP<140 mmHg both in 2004 and 2009 were divided into the continuously normal group, participants with SBP≥140 mmHg in 2004 and <140 mmHg in 2009 were divided into the reduced group, participants with SBP<140 mmHg in 2004 and ≥140 mmHg in 2009 were divided into the elevated group, and participants with SBP≥140 mmHg both in 2004 and 2009 were divided into the continuously high group. Multivariable logistic regression model was used to analyze the correlations of SBP with uric acid, blood lipid and blood glucose. Results: A total of 5 086 subjects were included in this study with a mean age of (48.0±7.2) years, including 2 374 males (46.67%) and 2 712 women (53.33%). The median (interquartile range) of SBP was 117.00 (13.33) mmHg in the continuously normal group, 146.67 (15.33) mmHg in the reduced group, 122.67 (12.00) mmHg in the elevated group and 150.67 (18.66) mmHg in the continuously high group. Multivariable logistic regression analysis showed that compared with the continuously normal group, the reduced group was correlated with abnormal fasting blood glucose (OR=1.383, 95%CI: 1.008-1.896); the elevated group was correlated with abnormal uric acid (OR=1.495, 95%CI: 1.195-1.869), abnormal low density lipoprotein cholesterol (OR=1.226, 95%CI: 1.030-1.460), abnormal triglyceride (OR=1.446, 95%CI: 1.203-1.739) and abnormal total cholesterol (OR=1.261, 95%CI: 1.057-1.504); the continuously high group was correlated with abnormal uric acid (OR=1.603, 95%CI: 1.188-2.164), abnormal triglyceride (OR=1.619, 95%CI: 1.253-2.093) and abnormal fasting blood glucose (OR=1.565, 95%CI: 1.166-2.100), adjusting for confounding factors (gender, age, marital status, etc.). Conclusion The increase of SBP in adults were correlated with uric acid, blood lipid and blood glucose.

In order to observe the effect of the immune and weight of chickens after use the attenuated vaccine with low dose of chicken infectious anemia virus (CIAV). In this study, the effects of low dose of CIAV on the weight of SPF chickens and NDV antibody production were observed by simulated experiments. The results showed that 10 EID50 and 5 EID50 CIAV per plume attenuated NDV vaccines were used to cause the weight loss of SPF chickens. Compared with the use of the non contaminated vaccine group, it has significant difference. And NDV antibody levels compared with the use of the non contaminated groups also decreased after use the vaccine with two doses of CIAV contaminated. It has significant difference. A certain proportion of CIAV antibody positive was detected at the beginning of the second week after use the NDV vaccine with two doses of CIAV contaminated. The detection of a high proportion of CIAV nucleic acid was detected in the first week after the use of a contaminated vaccine. The results of the study demonstrate the effects of CIAV pollution on the production and immune function of SPF chickens, and it is suggested that increasing the detection of viral nucleic acid can help save time and improve the detection rate in the detection of exogenous virus contamination by SPF chicken test method.
