Galectins can recognize and specifically bind to β-galactosidase,and regulate the transformation and survival of tumor cells,and promote the migration and metastasis of tumor cells,etc.Galectins correlate with tumor diagnosis,progression and prognosis.Galectias also can serve as immunoregulatory molecules to regulate the survival,activation,proliferation and differentiation of immune cells,and are components of tumor immune microenvironment.

Two hundred and forty patients with primary hypertension in Weifang Community were randomly sampled as contract group and another 240 hypertensive patients were sampled as control group.Patients in contract group signed service contract with general practitioners (GPs),who provided individualized service for hypertension management.Patients in control group receive conventional outpatient service for hypertension management.The clinical data of patients before and one year after contracted services were documented and compared with those in control group.The results showed that in contract group the average systolic pressure decreased from 134.60 mm Hg (1 mm Hg =0.133 kPa) to 130.62 mm Hg (P =0.000),reaching-the-target-BP rate increased from 56.3％ to 85.5％ (P =0.000),serum total cholesterol and triglyceride decreased significantly one year after receiving contracted services (P =0.000) ; while these indicators were not significantly changed in control group (all P ＞ 0.05).The results indicate that the contracted services of GPs can improve the effectiveness of hypertension management in community.

Objective: Patient-reported outcome (PRO) method was used to evaluate clinical effects of acupuncture for cervical spondysosis. Methods: With RCT method used, 162 cases were adopted, and 150 cases finished the whole course (treatment group: 76 cases, control group: 74 cases). Treatment group cases were treated by real-acupuncture while control group cases treated by sham-acupuncture. Northwick Park Pain Questionnaire(NPQ)was used as main outcome index, while SF-36 as secondary index. Both groups’ patients were evaluated before and after treatment course, plus one month and 3 months after the end of the treatment course. Results:Treatment group cases got lower NPQ Scores and higher mental health dimensions scores than the control group cases at any evaluation time-point. At the point of one month after the end of the treatment course, the treatment group cases got better social function scores than the control group cases. At the point of three months after the end of the treatment course, the treatment group cases got better body pain and energy scores than the control group cases. Multiple regression analysis showed that three dimensions of SF-36 (social function scores body pain and energy scores) had close relationship with NPQ scores. Conclusion: Acupuncture had satisfactory long-term effect for cervical spondylosis.

Objective:To establish a method for isolating tumor infiltrating dendritic cells(TIDC)from mice models of Lewis lung cancer by positive selection using anti-CD11c magnetic beads.Methods:A total of 1.0?10~6 Lewis lung cancer cells were subcutaneously injected into a C57BL/6 mice at the lateral abdominal wall to establish the mouse model of lung cancer.TIDC were isolated positively using anti-mouse CD11c magnetic beads;they were labeled by anti-mouse CD11c,and then the purity of the isolated cells was tested by FACScan flow cytometer.The cells were also double labeled by PE-conjugated MHC-ⅡmAb and FITC-conjugated CD83 mAb or FITC-conjugated CD86 mAb to analyze the phenotype of cells by FACScan flow cytometer.Results:The positive selection using anti-CD11 c magnetic beads isolated(1.73?0.31)?10~6 TIDC from each gram of Lewis lung cancer tissue,which accounted for(2.18?0.29)%of the cells in the tumor tissues.The purity of TIDC was 96.49%.Electron microscope showed that the isolated TIDC had the typical character of DC cells.The positive rates of MHC-Ⅱ,CD83 and CD86 molecules in TIDC surface were(51.25?4.21)%, (3.48?0.34)%and(3.07?0.65)%,respectively.Conclusion:The positive selection using anti-CD11c magnetic beads is highly effective,simple,and economic,and is worth popularizing.

Objective: To study the effects of deguelin on proliferation and apoptosis of human breast cancer cell line MCF-7 and on phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway. Methods: After treatment with 0, 1, 5, 10, 15 and 20 μmol/L of deguelin for 6, 24, 48 and 72 hours, the proliferation inhibition rate of MCF-7 cells was measured by cell counting kit-8 assay. Apoptosis rate of MCF-7 cells was detected with Annexin V-fluorescein isothiocyanate/propidium iodide double staining by flow cytometry and the apoptotic morphology was observed under a transmission electron microscope. After treatment with 0, 1 and 5 μmol/L of deguelin for 6 hours, 5 proteins involved in the PI3K/Akt signaling pathway were examined by Western blot analysis. Results: Deguelin at doses of 5, 10, 15 and 20 μmol/L inhibited the proliferation of MCF-7 cells at 6, 24, 48 and 72 hours. There was a significant difference in each group compared with the control group (P<0.01). The inhibitory effect was more marked with increasing concentration and duration of treatment. There were statistical differences (P<0.05) among 5, 10, 15 and 20 μmol/L groups. However, 1 μmol/L of deguelin had no obvious effects on the proliferation of MCF-7 cells at 6, 24, 48 and 72 hours, showing no significant difference compared with control group (P>0.05). Deguelin at doses of 5, 10, 15 and 20 μmol/L induced apoptosis of MCF-7 cells at 6 hours. There were significant differences (P<0.01) in the early and late apoptosis rate between the treated groups and the control group. The typical apoptotic MCF-7 cells were observed under the transmission electron microscopy. However, 1 μmol/L of deguelin had no apparent effect in inducing apoptosis of MCF-7 cells at 6 hours. After treatment with 5 μmol/L of deguelin for 6 hours the expression of phosphorylated phosphatase and tensin homologue deleted on chromosome 10 (PTEN) (Ser380), phosphorylated 3-phosphoinositide-dependent protein kinase 1 (PDK1) (Ser241), phosphorylated Akt (Thr308) and phosphorylated glycogen synthase kinase-3β (GSK-3β) (Ser9) proteins were significantly reduced in MCF-7 cells, while there was no significant change in the expression of total Akt protein. However, after treatment with 1 μmol/L of deguelin for 6 hours, there was no apparent change in the expression of these 5 proteins. Conclusion: Deguelin can inhibit the phosphorylation of GSK-3β (Ser9) via inhibition of the phosphorylation of PTEN (Ser380) and PDK1 (Ser241) pathway, thus inducing apoptosis and inhibiting proliferation of MCF-7 cells.

The biobank for medical researchers is a resource of significant utility , which also causes a series of ethical issues. For example, the question of what kind of informed consent should be adopted for the biobanking tissue residue, whether related study can be conducted without the donors' consent and how to accomplish the biobank research. Based on ethical principles of donation, individual rights of donor and common interest of the society, this study suggested the informed consent that to which extent can be accepted for biobank and which type should be adopted in different scenes with two feasible choices. One is the irreversible, and the other is the reversible anonymization process for samples. The necessity and rationality of informed consent for biobank con-struction were also evaluated in order to provide references for the ethical practice of biobank research.

Issues related to bioethics research often involve four basic principles , which are the value and integri-ty of the research, respect for human being, risk to benefit ratio, and the justice in subject selection. These prin-ciples contribute to the basis of bioethics for human-involved studies and they are capable of being applied to other relevant fields including complementary and alternative medicine (CAM) researches. The World Health Orga-nization (WHO) guidelines related to CAM studies clarify that the consideration should be taken for the human rights based on different value systems caused by social, cultural and historical problems, and the ethical prob-lem involved in CAM clinical studies should be properly handled in the further studies. Based on the four prin-ciples and Chinese traditional culture, the author attempted to discuss controversial bioethical issues such as the understanding and setting of informed consent, risk and benefit in western culture bioethics in order to analyze possible issues in the ethical review of Chinese medicine clinical research. We hoped that these considerations can provide references to the bioethical understanding of Chinese medicine clinical studies and ethical review on Chinese medicine practice .
