Objective To study the efficacy and safety of endoscopic submucosal dissection ( ESD ) for colorectal neuroendocrine tumor .Methods Clinical data of 43 cases of colorectal neuroendocrine tumor receiving ESD therapy from Sep .2010 to Feb.2014 were retrospectively analyzed , and the safety and efficacy were evalua-ted.Results All the 43 cases received ESD therapy , among whom 2(4.65%)cases developed delayed bleeding and recovered after endoscopic treatment .No perforation was found .4 cases had high fever and recovered after antibiotic treatment.One case(2.33%)of recurrence was found by colonoscopy 1 year later, and underwent sur-gery.The other 42 cases were followed up for 6 months to 2 years, during which no recurrence or metastasis was found.Conclusion ESD is a simple, safe and effective modality for colorectal neuroendocrine tumor .

OBJECTIVE:To probe into the general regularity and characteristics of ADR in our hospital. METHODS:117 ADR reports were analyzed retrospectively in respect of the patient’s gender,age,dosage form,route of medication,medication combination,category of drugs,involved organs and system and clinical manifestation,ect. RESULTS:Of total 117 cases of ADR,female cases of 69 accounted for 58.97% while 48 male cases 41.03%. ADR cases were mainly found in the group aged from 41 to 50(23.93%). ADR was predominantly caused by intravenous drip infusion(86.32%). 46 kinds of drugs in 10 categories were involved,in which antimicrobial drug took dominate place including 20 kinds in 10 categories(58.97%). The most common clinical symptom represented as lesion of skin and its appendants(54.70%). 117 cases were cured and improved without death case. CONCLUSION:Great importance should be attached to rational use of drug and safety of drug use of special population.

In the presence of silver ion, Mn2+ could be electro-oxidized to potassium hypermanganate in phosphoric acid solution, which could effectively react with pyrocatechol in acid solution and luminol in sodium hydroxide solution to produce chemiluminescence. On the basis of this, a novel indirect approach for the detection of Mn2+ was established. The effect of silver ions on the electrochemical oxidation of Mn2+was studied. when 1. 5 ×10-5 mol/L Ag+ and 0. 01 mol/L phosphoric acid solution were used in the process of electrochemical oxidation, the CL intensity could be up to the maximum value after the above solution was electrolyzed for 2 min. The relation of CL intensity and Mn2+concentration in the solutions at different pH and the selectivity were also investigated. when the pyrocatechol was used as luminescent reagent in the acidic medium, the CL intensity was linearly to the Mn2+concentration in the range of 1. 82×10-7-7. 27×10-5 mol/L with excellent selectivity. Common ions had little interferences in the determination of Mn2+. The method was successfully applied to the determination of Mn2+ in surface water and drinking water with satisfactory results.

The clinical pharmacist involved in the treatment of one case of phantom limb pain from the aspects of doctor's order reorganization,dose adjustment of analgesic drugs,pain score monitoring,ADR monitoring and medication education. And significant effects were shown in the drug use safety and the pain improvement in the patient. Therefore,the participation of clinical pharmacist in pain treatment can optimize analgesic effects,detect adverse drug reactions timely and thus obtain more benefits for patients.

Objective To investigate the influences of culture conditions on the in vitro induction and maturation of dendritic cells by using different combinations of cytokines. -ethods Mouse bone mar-row cells were isolated and cultured in media containing varying combinations of cytokines, including granu-locyte-macrophage colony stimulating factor (GM-CSF), interleukin-4 (IL-4) and fms-like tyrosine kinase 3 ligand (Flt3L). After cultured at 37℃ for seven days, the attached bone marrow cells were collected and stained by fluorescence-labeled monoclonal antibodies (McAb) against CD11c, MHCⅡ and CD86 for flow cytometry analysis. In the parallel group, LPS was added on day 5 to a final concentration of 1μg/ml for DC maturation analysis by flow cytometry. Results In group Flt3L (20 ng/ml)/GM-CSF (20 ng/ml)/IL-4 (10 ng/ml), 90％ of bone marrow cells were CD11c-positive. Flt3L (100 ng/ml) could induce 88％ of bone marrow cells to express CD11c. Bone marrow cells positive for MHCⅡ accounted for 35. 4％ and 36. 1％ in group Flt3L/GM-CSF/IL-4 and group Flt3L/GM-CSF, where both Flt3L and GM-CSF were used at a concentration of 20 ng/ml. After LPS stimulation, the positive rates of MHCⅡ in group Flt3L/GM-CSF/IL-4 and group Flt3L/GM-CSF were 58. 1％ and 59. 6％, which increased by 22. 7％ and 23. 5％, re-spectively. The percentages of CD86-positive bone marrow cells were 7. 1％ and 5. 5％ in group Flt3L/GM-CSF/IL-4 and group Flt3L/GM-CSF. Bone marrow cells positive for CD86 grew by 7. 1％ and 6. 2％ in group Flt3L (20 ng/ml) and group GM-CSF/IL-4 after LPS stimulation. Conclusions Flt3L and GM-CSF probably dominated the differentiation and maturation of bone marrow-derived dendritic cells with a synergis-tic effect. Combined usage of Flt3L and GM-CSF at the concentration of 20 ng/ml would be an optimal proto-col for DC research.

Organ preservation fluid could mitigate cold ischemia injury and maintain normal function of the grafts. At present, how to reduce a series of injury caused by cold ischemia of donor liver and improve the preservation quality of grafts are the hot and challenging spots in this field. Currently, preservation fluid in clinical practice has not achieved ideal preservation effect, especially for the protection of marginal donor organs. In the context of severe donor shortage, the key solution is still to explore the optimal preservation protocol for donor liver to prevent grafts from cold ischemia injury. In this article, the mechanism of donor liver injury during cold ischemia, the classification and evolution of donor liver preservation fluid were summarized, the development direction and challenges of donor liver preservation fluid were discussed, aiming to provide novel ideas and references for the research and development of donor liver preservation fluid.
