Type 2 Diabetes Mellitus(T2DM) is classified as two types according to somatotype,one is obesity or overweight,the other is normal or emaciation.It can also be classifi ed as two types according to symptoms,one is accompanied with typical syndromes(polyuria,polydipsia,polyphagia and weight loss),the other one is not.Generally speaking,the typical syndrome is not obvious among the patients with obesity or overweight,which is coincident with the theory about stuffy and fully sensation in the middle energizer and interior heat mentioned in emperor’s internal classic.So the therapeutic method is regulating the function of the middle energizer,evacuating full and stagnation,resolving phlegm and removing pathogenic heat.The typical syndrome is obvious among the patients with normal bodily form or emaciation,which is according with the traditional theory about defi ciency of yin and dryness-heat.So the therapeutic method is nourishing yin and clearing heat.The two types above are absolutely different.

Methods:According to the safety standards and technical reports issued by the International Atomic Energy Agency (IAEA) and combined with specific conditions in China, the operational intervention levels suitable for applying in China are analyzed. Results: The newly published IAEA technical report provided special operational intervention levels for emergency at a light water reactor. The recommended values are practical that our country can use for reference. Conclusion: It is suggested that the related branches for response to nuclear emergency in China establish feasible operational intervention levels by referring to the IAEA reports and taking into account the special conditions of nuclear facilities in China, in order to improve the capability of medical response to nuclear emergency.

Objective To investigate the effect of CD40/CD40 ligand on the genesis and development of coronary artery disease (CAD),and the inhibitory effect of cyclosporine A (CsA) on CD40/CD40 ligand. Methods A total of 71 patients were divided into four groups:acute myocardial infarction group (AMI, n=19), unstable angina pectoris group (UAP, n=18), stable angina pectoris group (SAP, n=17) and normal control group (N, n=17). Flow cytometry was used to detect the expres?sion of CD40 and CD40L in peripheral blood mononuclear cells (PBMCs) of four groups. The group in which CD40 and CD40L were produced at the highest level was chosen, and a series concentrations of CsA(H1:0 mg/L, H2:0.01 mg/L, H3:0.1 mg/L, H4:1 mg/L)were used to treat the cells. Then the expressions of CD40 and CD40L were measured by flow cytome?try. Results Compared with N group,the expression of CD40 was significant higher in other groups (P<0.05). The expres?sion of CD40 was significant higher in UAP group and AMI group than that of SAP group. There was no significant difference in the expression of CD40 between UAP group and AMI group (P>0.05). The expression of CD40L was elevated and fol?lowed by different severity of CAD. There was significant difference in the expression of CD40L between groups (P<0.05) . AMI group showed the highest expression of CD40 and CD40L. After being treated with CsA, the expression of CD40 was higher in H1 group than that of H3 group and H4 group (P<0.05). The expression of CD40L was significantly higher in H1 group than that of other three groups (P < 0.05). Conclusion CD40 and CD40L may be involved in the development of CAD. Moreover, it might be restrained by CsA via regulation of CD40/CD40L.

BACKGROUND:Enriching material for bone marrow stem cells is a current research hotspot. Preparation and screening of a new type of bone marrow stem cells-enriched material is crucial for the development of tissue engineering and clinical applications. OBJECTIVE:To observe the surface character and effect of a new type of bone marrow stem cells-enriched material on enriching bone marrow stem cells of decalcified bone matrix decorated with poly-L-lysine by selective cellretention technology. METHODS:Decalcified bone matrix was decorated with poly-L-lysine as the scaffold material. Bone marrow mesenchymal stem cells were col ected by using selective cellretention technology. Control group was decalcified bone matrix and experimental groups were Decalcified bone matrix decorated with poly-L-lysine at different concentrations (0.01%, 0.05%, 0.1%, 0.5%, 1%) with freeze-drying method. Material components were analyzed by Raman spectrum and infrared spectrum. Pore size, porosity, surface and cross section were observed under three-dimension video microscope and scanning electron microscope. The number of bone marrow nucleated cells, fibroblast colony-forming units and platelets were counted pre-and post-enrichment. RESULTS AND CONCLUSION:Decalcified bone matrices were covered with wel-distributed and dense poly-L-lysine. The poly-L-lysine/decalcified bone matrix had a high porosity with much more internal y connected pores. After enrichment with enriched material prepared by 0.1%poly-L-lysine, the number of bone marrow nucleated cells, fibroblast colony-forming units and platelets were increased (3.18±0.31), (5.25±1.40) and (3.88±0.68) times, respectively;the binding efficiency were (53±12)%, (73±13)%and (34±10)%, respectively;the selective rate of fibroblast colony-forming units was 1.41±0.34. The new constructed poly-L-lysine/decalcified bone matrix has good three-dimension space with high selective retention. It is an effective enriching material for bone marrow mesenchymal stem cells.
