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.

2.Effect of LFA-1 Deficiency on Differentiation of Mice Na?ve T Cells into Th17 Cells in vitro
Chinese Journal of Gastroenterology 2014;(11):644-649
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.

Chinese Medical Ethics 1995;0(04):-
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.
4.On the Interactive Ethical Relation between the Integration of Healthcare Resources and Humanistic Hospice Care from an Emotional Sense
Chinese Medical Ethics 1996;0(01):-
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.
5.Antibody Production Technology
China Biotechnology 2006;0(10):-
Ever from FDA approved the Rituxan in 1997,an Anti-CD-20 chimeric antibody,there have been more than 20 antibodies approved and they have got into more than 56 countries.About half approvied antibodies are curing kinds of cancers and seven of them have got a excellent sale targets to be "Blockbuster Drug".As the cell culture technology improving,the large scale cell expression titer comes from 1g/L to 5g/L.At the same time,the culture scale is coming form 12,000L to 15,000L,even 20000L and it can run several bioreactors at the same time.All these are make the improvement of the antibody purification.The new edition of media,system,chromatography technology and filtration technology can product the protein to several tens kilogram antibody per cycle and tons per year,although the productivity is only several kilograms per cycle many years ago.Also the new combined technology makes a two-step chromatography production protocol come into been.This will highly improve the antibody productivity and save the investment cost.

Objective To prepare icariin-loaded poly(lactic-co-glycolic acid) (PLGA) nanoparticles (icariin nanoparticles) and analyze their physical and chemical properties,the release of icariin,and the effects on human osteoblast cells in vitro.Methods Icariin nanoparticles were prepared by ultrasonic emulsification and dialysis method and characterized by transmission electron microscopy and particle size analyzer.The release studies in vitro were adopted to evaluate the release-control features.Thiazolyl blue tetrazolium bromide (MTT),alkaline phophatase activity assay,and calcium nodes dyeing were carried out to investigate the effects of icariin nanoparticles on the growth and differentiation of human osteoblast cells MG-63.Results The icariin nanoparticles had spherical shapes and uniform particle size,and the mean size of the nanoparticles was (185.8±5.6) nm.The icariin nanoparticles showed the best property of sustained release and biocompatibility.Meanwhile,the icariin nanoparticles had no effect on the growth of MG-63 ceils,but they promote the differentiation of osteoblast cells by a concentration-and time-dependent manner.Conclusions The icariin nanoparticles prepared by ultrasonic emulsification and dialysis method have a good effect on the differentiation of human osteoblast cells in vitro and are biocompatible.

Objective: To investigate the effect of Astragalus on peritoneal macrophages function in stable continuous ambulatory peritoneal dialysis(CAPD) patients. Methods: 28 stable CAPD patients were included in this study.All the patients were treated with peritoneal dialysis fluid containing Astragalus(20 ml/2 L) in vivo for one week.Peritoneal macrophages function such as phagocytosis ratio、bactericidal ratio、excretion of cytokines(TNF-? and NO) and mitochondrial dehydrogenases activity(MTT assay) were examined ex vivo just before and after the treatment. In vitro,peritoneal macrophages isolated from effluent were incubated with RPMI 1640、CDF or CDF containing various concentrations of Astragalus. Then peritoneal macrophages function mentioned above were examined again and compared. Results:No significant difference was found in TNF-? level in effluent between before and after the treatment (100?63)ng/L vs (116?60)ng/L, (P=0.192). While comparing with pre-treatment, peritoneal macrophages function was improved significantly after the addition of Astragalus into dialysate (phagocytosis ratio: (34.8?12.7)% vs (43.4?9.3)%,P0.05).The results in these two groups were significantly lower than those in Astragalus groups(P0.05). While significant decreasing in NO level and mitochondrial dehydrogenases activity were observed in 8% Astragalus groups as compared with those in 2% Astragalus group(P
