The event of “diagnosing mental disorder but actually not” violates patients′right of informed con-sent and refused to health , showing some problems of “diagnosing mental disorder but actually not” and mandatory admission process and psychiatric judicial authentication , and also have some ethical problems .Therefore, relevant departments should perfect the laws and regulation , establish a hospitalized psychiatric patients appeal , the appeal channels , at the same time , physicians should follow a correct understanding , respect patients rights , disinterest-ed, the ethical principles of self -supervision and also use constraints should be regulated .

OBJECTIVE:To evaluate the effect of temozolomide(TMZ)in combination with dexamethasone(DXM)on the proliferation of human gliocytoma U251 cells in vitro.METHODS:Human U251 cells were assigned to 1 of the 3 groups: TMZ(10,25,50,100,200,400?mol?L~(-1),respectively)alone or in combination with 40?mol?L~(-1)DXM(TMZ+DXM group)or control group(none drug).After treatment for 72 hours,the cell morphology,cell inhibition ratio,cell cycle and the apoptotic rate were detected.RESULTS:When TMZ concentration was greater than 100?mol?L~(-1)the cell inhibition ratio was higher in TMZ-treated group than in TMZ+DXM-treated group(P

The Toll like receptors(TLRs)are essential transmembrane signaling receptors of the innate immune system that alert the host to the presence of a microbial invader.The recent discovery of the TLR has rapidly expanded our knowledge of molecular events that initiate host pathogen interactions.These functional attributes of the cellular receptors provide insights into the nature of pattern recognition receptors that activate the human antimicrobial defense systems.The fundamental significance of the TLR in the generation of systemic inflammation and the pathogenesis of septic shock is reviewed. The potential clinical implications of therapeutic modulation of these recently characterized receptors of innate immunity are also discussed.

Objective To analyze the differentially expressed proteomics on T lymphocyte in mice immunized with 14‐3‐3 recom‐bined vaccine and injected with phosphate buffer solution (PBS) .Methods Mice immunized with 14‐3‐3 recombined vaccine were separated in the experiment group and those injected with PBS were selected in the control group .Two weeks after immunization with 14‐3‐3 recombined vaccine ,total protein of T lymphocyte isolated from the two groups was collected and separated by using the two dimensional electrophoresis(2‐DE) .The differentially expressed proteomics were compared .Results The 2‐DE map shown 11 differentially expressed protein plots ,including 7 protein plots spotted in the 2‐DE map of T lymphocyte from 14‐3‐3 recombined vaccine immunized‐mice and 4 protein plots spotted in the 2‐DE map of T lymphocyte from PBS injected‐mice .Conclusion There are differentially expressed proteomics of T lymphocyte in PBS injected‐mice and 14‐3‐3 recombined vaccine immunized‐mice ,which could contribute to clarifing the mechanism on protective immunity of 14‐3‐3 recombined vaccine and optimizing vaccine strategy for improving vaccine effect .

The article gives a brief account of the application of clinical observation to the evaluation of medical students' core competence. It expounds the key points in the assessment about their professional values,attitudes and behavior, emphasizing the application scope, working principle and advantages and disadvantages in the rank evaluation as well as the methods to enhance the effectiveness of evaluation.

Poly ADP-ribose polymerase(PARP)inhibitor is a targeted biological agent for the treatment of ovarian cancer, which is mainly suitable for platinum-sensitive ovarian cancer patients. However, data from clinical trials showed that PARP inhibitors have certain therapeutic effect on platinum-resistant or platinum-refractory ovarian cancer patients. It may become a new hope for treatment of ovarian cancer patients in the future.

OBJECTIVE: The goal of this study was to study the mechanism of substance P (SP)-mediated the neural control of mast cell (MC) degranulation. METHOD: Bone marrow mast cells from mice were cultured with stem cell factor (SCF), IL-3 and IL-4 (group A) and SCF, IL-3 (group B) for four weeks. Then the cells were harvested and reserved for studies. Western Blot hybridization technique was used to detect the expression of FcεR I α and NK-1R on MCs from the two groups. Then such cells were activated with SP (0, 0. 01, 0. 10, 1. 00, 10. 00 µg/ml, respectively) for 30 min. The histamine released into the supernatant and stored in the protoplasm was quantified by enzyme linked immunosorbent assay (ELISA). And the percentage of histamine release was calculated as a percent of total histamine content. RESULT: The expressions of FcεR I α and NK-1R on these mast cells in group A were statistically higher than in group B (P<0. 05). The MCs from two groups can be actived when stimulated by SP, but the level of MC degranulation in group A was higher than group B (P<0. 05). CONCLUSION Neuropeptide may stimulate MC degranulation through immunological and non-immunological pathways. In summary, the current study provides us with better understanding of the mechanism of neuropeptide-controlled MC deranulation, and this should be helpful for the further research involved in the mechanism and treatmemt of airway hyper-reactivity.

· AlM: To analyze the clinical data of 54 cases misdiagnosed as optic neuritis and to explore measures to reduce misdiagnosis
· METHODS: This retrospective study comprised 54 patients that had been misdiagnosed as optic neuritis from September 2000 to June 2013. The misdiagnosis features were summarized.
· RESULTS:Many diseases can easily be misdiagnosed as optic neuritis, including ischemic optic neuropathy, intracranial tumors, optic nerve vasculitis, myelinated nerve fibers, and so on.
· CONCLUSlON: The measures to reduce misdiagnosis consisted of detailed history collection, perfect physical examination and comprehensive expertise of fundus disease.

Retinal degenerative disease is the leading cause of visual loss,the mechanism is not clear and has no effective treatment method.In recent years,the field of stem cell research has made great progress.Stem cells have the potential of differentiating into all the body cells.Embryonic stem cells (ESCs) can be used to differentiate a variety of retinal cells,which has brought a new promise for the treatment of retinal degeneration disease.However,the most important step of this treatment is how to differentiate ESCs into photoreceptor cells and retinal pigment epithelium (RPF) cells.In this paper,we introduced the recent progress in the differentiation methods of ESCs into retinal cells,which contains spontaneous differentiation method,co-culture method,growth factors and small molecules induced method,adherent monoculture method,three dimensional differentiation method.
