Carotid artery stenosis is the main cause for transient ischemic attack(TIA)and cerebral ischemic stroke. Carotid artery stenting(CAS)therapy has provided a new approach for carotid artery stenosis with safety of causing slight wound and less complication. It also gives opportunities to the patients with contraindication to carotid artery endarterectomy(CAE). There is similar tendency between CAS and CAE involving the secondary prevention of stroke in experiments. The safety and efficacy of the stenting depend on the normative operation and complete evaluation of cerebral hemodynamics and functions before hand. With application of the technique of preventive filter devices and progressing preventive technology against restenosis, the interventional therapy is going to play a more important role in the therapy of carotid stenosis.

According to the traditional Chinese medicine (TCM), atopic dermatitis (AD) is believed that it is caused by innate constitutional insufficiency and dysfuction of heart and spleen. Thus, the treatment includes strengthening the spleen and clearing dampness, nourishing blood and moisturing skin. This paper reviewed literature about the researches on AD, and summarized the etiology and pathogenesis of the disease in order to investigate new treatment.

Objectives To establish culture system for unilineage differentiation of umbilical cord blood CD 34 + cells into granulocytes, erythrocytes or platelets. Methods After CD 34 + cells were separated by midiMACS using micro beads conjugated with anti-CD 34 monoclonal antibody, these cells were induced to specifically differentiate along granulocyte, erythrocyte or platelet by adding appropriate hematopoietic growth factors including SCF plus G-CSF, EPO or TPO. Then morphology, immunological phenotype and function analysis were performed to identify these induced cells. Results After induced unilineage differentiation, the percentages of CD 15 +, GPA + and CD 41 + cells were 81 17%, 95 35% and 77 82%, respectively. These induced cells acquired terminal cell's morphologies. The cells from the granulocytic culture had the ability to phagocytose Chinese ink and plate-like particles could aggregate under the action of thrombin. Conclusion The culture system for unilineage differentiation of CD 34 + cells into erythrocytes, granulocytes, or platelets was established, which was a basis for the research about cell treatment, gene regulation and exogenous gene expression in hemopoiesis.

Objective:This study evaluated the economical effects of two different regimens for metastatic breast cancer, namely, paclitaxel plus either carboplatin (TP) or epirubicin (TE). Methods:The cost-effectiveness method in pharmacoeconomics was adopted to analyze retrospectively the two different regimens. Results:The median follow up was 23.5 (range:9 to 42) months. The overall response rate for TP and TE were 78.33%and 80.00%, respectively. The 1-and 2-year progression-free survival rates of TP and TE were 43.6%and 38.9%and 10.8%and 17.4%, respectively. The 1-and 2-year overall survival rates were 80.3%and 78.3%, respectively for TP, whereas the corresponding values for TE were 53.2%and 47.9%. No statistically significant difference was found between the two groups (P>0.05). Cost-effectiveness analysis showed that the average costs of the TP and TE regimens were 10 303.8 and 13 853.3 yuan, respectively, with corresponding cost-effectiveness ratios of 131.54 and 173.17 (P<0.01). For the chemotherapy toxicity, the alopecia reactions of the TP group were significantly lower than those of the TE group (P<0.01). Conclusion:The short-and long-term efficacies of the two regimens were similar. TP regimen was the optimal scheme for advanced metastatic breast cancer.

Objective To investigate the role ot adhesion molecule CD44 in respiratory syncytial virus (RSV) infection induced bronchiolitis.Methods Thirty-six children with RSV infection induced bronchiolitis (infection A group),34 children with only RSV infection (infection B group) and 40 healthy children (control group) were selected.The proportion of peripheral blood CD44+ cell was determined by flow cytometry.The levels of peripheral blood interferon (IFN)-γ,interleukin (IL)-4,IL-10 and IL-12 were determined by enzyme-linked immunosorbent assay.Results The expression of CD44 and the level of IL-4 in peripheral blood in infection A group were significantly higher than those in infection B group and control group,there were statistical differences (P ＜ 0.05).The level of IFN-γ in peripheral blood in infection A group was significantly lower than that in infection B group and control group,there were statistical differences (P ＜0.05).The levels of IL-12 in peripheral blood in infection A group and infection B group were significantly lower than that in control group,there were statistical differences (P ＜ 0.05).There were no statistical differences in the level of IL-10 in peripheral blood among the 3 groups (P ＞ 0.05).In the children with RSV infection,the expression of CD44 in peripheral blood was positively correlated with the level of IL-4 (r =0.798,P ＜ 0.05),the level of IL-12 was negatively correlated with the level of IL-4 (r =-0.186,P ＜0.05).Conclusion The expression of adhesion molecule CD44 may play a role in the RSV infection induced bronchiolitis,and the high expression of CD44 in children with RSV infection may increase the susceptibility to bronchiolitis.
