Objective To study wrong diagnosis in the patients with epidemic hemorrhage fever in the early stage. Method To analyze the data such as the time of making wrong diagnosis,the wrong diagnosis,the department of treatment and the hospital of treatment before the diagnosis was made and the relationship between the clinical type and making wrong diagnosis. Results Making wrong diagnosis in the patients with epidemic hemorrhage fever was common (88.97%),and it was more happened in the early stage,in the non-typical and mild patients and in the lower grade hospitals.The wrong diagnosis rate (28.95%,11/38)was lower in the Infectious disease department than in the other department (93.65%),P

Objective To study the protection of mouse bone marrow-derived mesenchymal stem cells ( MSCs) for allogenic islets. Method MSCs from C57BL/6 mice were preceded to a 24-well culture plate with the density of 3 × 104/well. On the second day, islets were isolated, purified and divided to undergo streptozotocin (STZ) induced chemical injury and mixed lymphocyte reaction ( MLR) respectively. Then, treated and control islets were respectively divided into the following groups: islets + MSCs, STZ-islets + MSCs, and MLR-islets + MSCs. As control groups for their counterparts, treated or non-treated islets were also cultured without MSCs. On the 5th day incubation, glucose-stimulated insulin secretion test was performed to assess the function of islets in different groups, comparing their insulin-secretion amount stimulated by low or high glucose and the stimulation index determined by the ratio of (insulin amount secreted under high-glucose stimulation)/(insulin amount secreted under low-glucose stimulation ). Islet viability was evaluated by acridine orange (AO)/propidium iodide (PI) fluorescence staining. Result As shown by AO/PI staining, large numbers of dead cell with red fluorescence could be observed in STZ- or MLR- treated islets without MSCs, while the number of dead cells obviously reduced in MSC-cocultured islets with increased viable cells of green fluorescence. STZ- or MLR- treated islets exhibited apparently decreased insulin-secretion amount either under low- or high-glucose stimulation, as well as the stimulation index. The insulin-secretion function was significantly improved in islets cocultured with allogenic MSCs (P ＜ 0. 05 ). Conclusions Bone marrow-derived MSCs can protect isolated allogenic islets against chemical and immunological injury.

Objective To study whether the viral metabolites can make influence on biological behavior of mesenchymal stem cells (MSCs) and to provide evidence for safe MSCs transplantation.Methods MSCs were isolated from bone marrow of C57BL/6 mice and the mRNA level of Toll like receptor 3 (TLR3)was detected.In vitro polyinosinic-polycytidylic acid [poly(I ∶ C)] was used as the product of viral metabolite to stimulate MSCs.We recorded the change of MSCs in terms of self-renewal,multi-directional differentiation,directional migration and immunosuppression by flow cytometry,PCR etc.Results ①Low-expressed TLR3 mRNA was dectected in MSCs and it was upregulated after being stimulated by poly(I ∶ C).②After being stimulated by poly(I ∶ C)for 24,48,and 72 hours,the self-renewal ability of MSCs had no statistical difference with that of the control group(P ＞0.05).However,poly (I ∶ C)promoted the differentiation of MSCs to lipoblast and osteoblast (P ＜ 0.01).③The directional migration ability of MSCs was weakened significantly by poly(I ∶ C) stimulation.After being stimulated for 6,12,and 24 hours,the migration rate of MSCs was(82.83 ± 1.69) ％,(87.80 ± 3.58) ％,and (92.67 ± 2.52) ％ respectively compared to that of the control group.The difference had statistical significance(P ＜0.01).④MSCs had great immunological suppression ability and it was dependant on the number of MSCs.After being stimulated by poly(I ∶ C),the ability of MSCs' immunological suppression on proliferation of activated splenocytes was not impaired and the difference had no statistical significance compared with that of the control group(P ＞0.05).Conclusion While maintaining the viability and immunosuppression function of MSCs,viral metabolite inhibits migration of MSCs,holds them in the transplanted position and protects the graft,providing evidence for MSCs as seed cells in the treatment of diabetes and other immune disorder diseases.

Measles virus is an enveloped virus with a non-segmented negative-sense RNA genome. Two envelope glycoproteins on the viral surface, namely hemagglutinin (H) and membrane fusion protein (F), are responsible for the virus entry into susceptible host cells. The specific interaction between H and its cellular receptors is a key step in successful virus infection, determining the infectivity and tissue tropism of the measles virus. Thus far, three H receptors have been identified, including the complement regulatory molecule CD46, the signaling lymphocyte activation molecule (SLAM) and the cell adhesion molecule Nectin-4. Here, we reviewed our molecular understanding on the recognition mechanism of these receptors by the viral H protein, aiming to promote future studies on antiviral drug design and measles virus-based oncolytic therapy.
