Serotonin and its receptors exist extensively in gut,5-HT3 receptor is ligand-gated ion channel.It is composed of five subunits,S-HT3A ,5-HT3B ,5-HT3C ,5-HT3D and 5-HT3E .The genetics of serotonin receptors appear to be associated with irritable bowel syndrome.5-HTTLPR genetic polymorphisms influence the efficacy of serotonergic treatments. As a new generation of developed 5-HT3 receptor antagonists, alosetron and ramosetron act an important role in regulating gastrointestinal motility and visceral perception. They are efficacious in the treatment of irritable bowel syndrome. Ramosetron show high affinity for 5-HT3 receptors,dissociate slowly from 5-HT3 receptors and show long-lasting 5-HT3, receptor antagonism.

The natural instinct of medical science is the study of human being.To build a humane medical science,we must come back to the origin of metaphysical human-orientation,and persist in upholding the consistency of the trinity of nature,knowledge and mankind.With the human-oriented core values,we can regulate and direct the whole process of healthcare service,enabling it to gain the nourishment of the humane spirit.Aiming to seek solutions to the tense relationship between doctors and patients as well as the complex procedure and high cost of healthcare service from the cultural origin,it is therefore extremely significant to improve the humane cultivation for medical staff.

Objective To explore the factors that may influence the compliance of medical workers in dealing with classifying medical wastes. Methods One hundred and sixteen medical workers participated in this investigation by applying self-designed questionnaire and live observation mode. Influential factors were evaluated by multi-factors analysis. Results The compliance percent of 116 medical workers was only 69.9%(351/502), which caused by low awareness of medical wastes. As much as 20.12 % (101/502) medical workers made mistakes when dealing with infectious wastes. Working experience, awareness of medical wastes, instruments and working load were associated with compliance of medical workers (P<0.05). Conclusions Low compliance of medical workers dealing with medical wastes were related to lacking working experience, low awareness of medical wastes, inappropriate instruments and heavy working load. In this case, improving management system of medical wastes, regular training and assessment, adding instruments and identification of medical wastes, increasing medical workers and simplifying the working process are effective approaches in increasing compliance of medical workers in dealing with medical wastes and improving quality of nursing management.

Objective To compare the in vitro activity of anti-human T lymphocyte porcine immunoglobulin(P-ATG)prepared by Cohn ethanol fractionation and ammonium sulphate precipitation,commercial rabbit anti-human thymocyte immunoglobulin(trade name:Thymoglobuline),and anti-human T lymphocyte rabbit immunoglobulin(trade name:Grafalon)so as to evaluate the properties of P-ATG prepared by two processes.Methods The four products were detected for the antibody-dependent cell-mediated cytotoxicity(ADCC)by lactate dehydrogenase(LDH)method,measured for the complement dependent cytotoxicity(CDC)by CCK-8 assay,and detected for the affinity for binding with different T cell antigens(CD3,CD4,CD8)by double immunofluorescence staining method.Results Among the four products,only Thymoglobuline at the high concentration(1 mg/mL)had a weak ADCC effect on human peripheral blood mononuclear cell(PBMC).All products could induce the CDC effect in human PBMC in a dose-dependent manner,among which the effect of Thymoglobuline was higher than that of P-ATG or Grafalon preared by two processes,about 3 to 4 times,and the effect of Grafalon was comparable to that of P-ATG.In the proportion of four products binding with T cell surface antigens CD3 and CD4 was similar,However the proportion of Thymoglobuline and Grafalon binding with CD8 antigen was slightly lower than that of P-ATG.Conclusion The in vitro activity of the P-ATG prepared by Cohn ethanol fractionation and ammonium sulphate precipitation was in good agreement,and was not lower than that of imported products at the clinical dose.

Objective:To investigate the effect of miR-26b on the invasion and migration of lung cancer cell and to explore its mechanism.Methods:qPCR was used to detect the expression of miR-26b in lung cancer.Luciferase reporter gene was used to detect interaction between miR-26b and hENT1.Transwell assay was used to detect invasion ability after treatment of miR-26b mimics.Scratch assay was used to detect migration ability after treatment of miR-26b mimics.The expressions of hENT1,ROCK-I and RhoA were detected by Western blot.The changes of cytoskeleton after miR-26b mimics treatment with phalloidin were observed.The effect of miR-26b mimics on the tumor size and volume of lung cancer was determined by subcutaneous tumor formation in nude mice.Results:MiR-26b expression was significantly reduced in lung cancer.With the progress of lung cancer,the expression of miR-26b was reduced.With the progress in differentiation of lung cancer,the expression of miR-26b was decreased.Decrease of miR-26b was associated with lung cancer lymph node metastasis.HENT1 was the direct target of miR-26b;miR-26b regulated the invasion and migration ability of human lung carcinoma A549 cells.MiR-26b regulated the expression of hENT1,ROCK-1 and RhoA.After the treatment with miR-26b mimics,the F-actin staining was significantly reduced,whereas the formation of wrinkles and the formation of pseudopodia were significantly reduced.Subcutaneous tumor formation in nude mice showed that miR-26b mimics treatment significantly reduced the tumor size and mass.Conclusion:MiR-26b plays a role in tumor suppression in lung cancer.miR-26b can regulate the invasion and migration ability of lung carcinoma A549 cells by targeting hENT1 depending on the RhoA/ROCK-1 pathway.
