BacKground:Lymphocyte function-associated antigen-1( LFA-1 ) pIays a cruciaI roIe in the pathogenesis of infIammatory boweI disease by reguIating the activation and function of T ceIIs. Aims:To investigate the effect of LFA-1 deficiency( LFA-1-/-)on differentiation of mice na?ve T ceIIs into Th17 ceIIs in vitro. Methods:LFA-1-/- mice were breeded and the progeny genome DNA was extracted from the taiIs for genotyping by PCR. CD4+CD62L+ na?ve T ceIIs were separated from spIenic mononucIear ceIIs of LFA-1-/- progeny mice and wiId type ( WT ) C57BL/6J mice, respectiveIy,by magnetic-activated ceII sorting( MACS),and then the purity of separated ceIIs was determined. Na?ve T ceIIs obtained were cuItured in different inducing systems[ transforming growth factor-β( TGF-β),TGF-β + interIeukin-6 (IL-6),and TGF-β + IL-6 + IL-23]in vitro for Th17 ceII differentiation;ceIIs in each inducing system were coIIected for anaIyzing the ratio of Th17 ceIIs by fIow cytometry,and the expressions of Th17-specific transcription factor ROR-γt and Th17-specific marker IL-17A were measured by qRT-PCR and ELISA methods. Results:AII fifteen progeny mice were identified as LFA-1-/- genotype. Purity of CD4+CD62L+ na?ve T ceIIs separated by MACS was above 95%. Th17 ceIIs couId be induced by Iow-dose TGF-βcombined with IL-6,and the differentiation ratio was increased obviousIy when IL-23 was added. In inducing system containing TGF-β,IL-6 and IL-23,na?ve T ceIIs from LFA-1-/- mice produced more Th17 ceIIs than those from WT mice(17. 2% ± 1. 4% vs. 5. 7% ± 0. 2%,P<0. 001),expressions of ROR-γt mRNA and IL-17A mRNA were up-reguIated(P<0. 001),and IL-17A concentration in ceII cuIture supernatant was increased(P<0. 01). Conclusions:Deficiency of LFA-1 promotes the differentiation of mice na?ve T ceIIs into Th17 ceIIs in vitro.

The article expounds the relationship of medical ethics and medical humanities education in a doctrinal aspect.Medical ethics possesses a more essential and inherent nature compared with medical humanities education,thus serves as the fundamental motivation and guide of medical practice for medical students and staff.Their relationship is clearly understood and the curriculum structure of medical education reasonably adjusted.The following will be beneficial reference for medical ethics cultivation for medical students: to strengthen all sidedness,positivism and interest of medical ethics education,medical humanities education served as evidence and complement for medical ethics education;to demonstrate ethical characteristics,profundity and intention of medical humanities education,medical ethics education also served as the aim and gist of medical humanities education.

The aging trend in China′s population sets an creasing demand for attention on senile people from both legal and emotional senses,including detailed and thoughtful humanistic hospice care.The traditional clinical service concept which values living while neglects dying should be modified,with a novel and overall humanistic hospice care for the dying and family members,in order to achieve the social harmony under the novel life value which enjoys living and a peaceful dying.

By using traditional Chinese medicine inheritance support system to analyze the dominant experience and recessive principles of the prescriptions for stranguria in the dictionary of traditional Chinese medicine prescription (DCMP), we aim to define the medication pattern and rule and to acquire new prescriptions. In dominant experience analysis, we were able to find 22 drugs used over 50 times, including drugs of clearing heat, diuresis and relieving stranguria which are the most used and drugs of clearing heat, cooling blood, benefiting Qi and nourishing Yin. In addition, drugs of activating Qi and Xue, eliminating phlegm and removing toxic are often used, including 34 herb pairs and 5 combinations of three-taste drugs are used more than 35 times. These results fully reflect the composition principles and compatibility characteristic of prescriptions for treating stranguria in DCMP. Thirteen new prescriptions by way of recessive principle excavating were acquired. These new prescriptions might be suitable to clinical treatments of variable syndromes. This article provides an useful clue to research and produce new drugs.
