Mesenchymal stem cells (MSCs) are adult stem cells which derived from the embryonic mesoderm. They have a high proliferative ability and can differentiate into various tissues of mesodermal origin including bone, cartilage and adipose tissue in vitro. Moreover, MSCs have also been shown to produce anti-inflammatory molecules which can modulate cellular and humoral immune responses. Because of their easy preparation, the capacity for self-renewal, multi-lineage differentiation and immunoregulatory effect, MSCs therapy becomes a promising tool in the treatment of tissue regeneration, anti-inflammation, and autoimmune diseases. In this review we will focus on the application of MSCs for nasal inflammation disease.

Objective To investigate the effects of alprostadil injection on IL-6, IL-8, TNF-αand insulin resistance in diabetic patients.Methods 90 patients with diabetes mellitus in our hospital from January 2014 to May 2016 were selected,and randomly divided into observation group and control group,45 cases in each groups.The control group received conventional western medicine , the observation group was treated with alprostadil injection.The levels of serum IL-6, IL-8, TNF-α, insulin and insulin resistance index were compared before and after treatment in both two groups. Results After treatment,the total effective rate of treatment group was 91.11%,which was significantly higher than the control group 71.11%( P<0.05).Before treatment,the levels of IL-6,IL-8,TNF-α,insulin and insulin resistance index of two groups were had no statistical significance,after treatment,the levels of IL-6,IL-8,TNF-α,insulin and insulin resistance index were decreased in both groups,and the observation group was significantly lower than the control group,the difference was statistically significant (P<0.05).Conclusion The alprostadil injection can significantly reduce the levels of IL-6,IL-8,TNF-α,and control the level of blood glucose,reduce the effect of insulin resistance.

Objective To establish inductively coupled plasma mass spectrometry(ICP-MS) method and determine the migration contents of twelve elements in clevidipine injectable emulsion direct contact with packaging materials.Methods Clevidipine injectable emulsion were digested by carbonization-oxidation.Based on internal standard method, migration contents of twelve elements in digested sample solutions were analyzed by ICP-MS.Results The linear correlative coefficients for twelve elements were higher than 0.9995.The accuracy, precision and stability of the method were detected, all of which conformed to the analysis standard.The recoveries were in the range of 81.3%~119.0%.Conclusion The packaging materials have good compatibility with injectable emulsion, and migration contents of Na、K、Sb and Ba of twelve elements meet the requirements.

Objective To conduct prospective randomized controlled clinical observation on patients with nasopharyngeal carcinoma under chemotherapy and radiotherapy using inhaling therapy with recombinant human interleukin 11,and the preventing and curing effect of recombinant human interleukin 11 on radiation-induced pharyngitis is evaluated.Methods 161 cases of newly diagnosed patients with head and neck cancer were selected under the principle of informed consent and these 161 cases were divided into the observation group (87 cases) and the control group (74 cases) based on randomization principle.In the observation group,when the dose reached 20Gy,then recombinant human interleukin-11 inhaling therapy was applied `ll the end of radiotherapy,for the control group,conventional treatment was applied in the event of radioactive throat.RTOG criteria were used during the observation in patients with the occurrence and treatment of radioactive pharyngitis.Results When compared with the control group,the average time for radioactivity to appear was prolonged,the severity decreased and the healing time was shortened in the observation group,those data were statistically significant.Conclusions Recombinant human interleukin-11 inhaling therapy can prevent and cure inhalation of radioactive pharyngitis and this therapy is better than conventional treatment.It's worthy of further study and clinical application.

Objective To investigate the reversal effect of triazole antifungal itraconazole,fluconazole combined with adriamycin on multidrug resistance in leukemia cells.Methods Human chronic myelogenous leukemia adriamycin resistant cell lines K562/ADR cells were incubated with itraconazole,fluconazole,or PSC833 (positive control) combined respectively with adriamycin.CCK-8 assay was used to assess cell proliferation of K562/ADR.The mean fluorescence intensity of intracellular ADR was measured by flow cytometry.The marker of DNA damage γH2AX was detected by Western blot.Results 1 μg/ml itraconazole and 0.5 μg/ml PSC833 can decrease K562/ADR IC50 of adriamycin from 38.30 μg/ml to 8.59 μg/ml and 24.64 μg/ml in a dose-dependent manner.K562/ADR cells were incubated with 1 μg/ml itraconazole or 0.5 μg/ml PSC833 combined respectively with adriamycin for 3 h and 6 h,the mean fluorescence intensity of intracellular ADR were increased 1.54-fold (3 h),1.50-fold (6 h) or 5.97-fold (3 h),5.83-fold (6 h).Itraconazole or PSC833 combined with adriamycin significantly increase the expression of γH2AX in K562/ ADR cells.Conclusion Itraconazole can recover adriamycin sensitivity of K562/ADR by increasing the concentration of intracelullar adriamycin and synergistically increasing DNA damage,but not for fluconazole.
