Objective: To explore the differences between the internal social adaptation and external social behaviors of freshmen. Methods: Make a survey of 198 freshmen on the internal adaptation and external by General Well-Being Schedule and Undergraduate Social Adaptation Questionnaires. Results:Freshmen' social adaptation mainly involves three factors: interpersonal communication, the state of campus life and performance of studies. The Cronbach alpha of 3 factors were 0.82, 0.87 and 0.90,and the re-test reliability was r=0.73 (P

The actuality of natural medicines in China,Europe,America,and Korea were explained, and analyzing existing problems of research and development of the natural medicines in China combing development trend of natural medicines,research trend,future direction,thought and methods for research of natural medicines were put forward in the paper.

Pain is one of important topics in Bioethics.Pain,which looks like a simple physical symptom,involves the crucial ethical value.In Western bioethics,pain has been discussed for some decades.However,pain still hasn't been emphasized as an important topic in Chinese Bioethics world.Therefore,from bioethical perspectives,this article attempts to study pain under four subtitles: the notion of pain;some bioethical debates about pain;narrative of pain and illness,and pain: a way to go further for Bioethics studies.

In modern world,bioethics has become an international social movement since its inception during the mid-twentieth century.In the practices of clinical bioethics,methodology is the most crucial issue concerned by western scholars.Briefly,the article introduces and analyzes the empirical approach in contemporary European world,as well as explains the interaction between bioethics and naturalism.Based on current development of mainstream ethics,the article also tries to answer the question about "is and ought" in the background of clinical practice.The research aims at providing the ideas and experiences for the development of Chinese clinical bioethics.

MicroRNA (miRNAs) are endogenous,small and noncoding regulatory RNAs,which widely exist in eukaryotes.MiRNAs regulate the expression of target gene by translating inhibition or mRNA destabilization.MiRNAs have been recognized as a major regulatory fashion of post-transcriptional gene expression and play important roles in many cellular biological processes,including cellular proliferation,diffcrentiation,cell death.Alteration of expression and/or dysregulation of miRNAs are related to a wide variety of severe fundus diseases,such as diabetic retinopathy,age-related macular degeneration and retinoblastoma.This review aimed to provide a summary of the recent progress in the effect of miRNAs on fundus diseases.

Objective To observe the therapeutic effect of red peony root decoction (RPRD) on model rats with acute pancreatitis (AP),and the effect on the expression of NF-κB,TNF-α and IL-6.Methods Forty SD rats were randomly divided into five groups:normal control group (group A),AP model groups (group B,24 h; group C,72 h) and RPRD treatment groups (group D,24 h; group E,72 h).There were 8 rats in each group.The AP models were induced by intraperitoneally injecting with L-arginine.After the model was established,rats of group B and group C were treated with intra-gastric instillation of NS,and rats in group D and group E with RPRD.At 24 and 72 hours after induction of AP,rats in each group were sacrificed and blood samples were taken for the measurement of serum amylase,TNF-α and IL-6.The expression of NF-κB p65 protein in the pancreas were detected by Western Blot,and pathological status of the pancreas were analyzed.Results The serum amylase level in group B and group D was significantly higher than that in group A (P＜0.05),and the level in group D was obviously lower than that in group B (P＜0.05).The serum amylase level in group C and group E was decreased,and there was no difference between group A (P＞0.05).The pathological severity and pathological scores of the pancreas in group D and group E were more lighter than those in group B and group C (P＜0.05).The level of serum TNF-α and IL-6 was significantly decreased in RPRD treatment groups (P＜0.05),group D compared with group B,[ (12.54±2.12)pg/ml,(552.88±81.27)pg/ml] vs.[ (20.53±4.16)pg/ml,(1255.75± 118.82)pg/ml]; group E compared with group C,[ (11.01 ±2.02)pg/ml,(582.87± 88.86) pg/ml] vs [ (23.85 ± 5.59) pg/ml,(1366.33 ± 163.16) pg/ml].The expression levels of NF-κBp65 protein in the pancreas of group D and group E were significantly lighter than those in group C at both time points (group D compared with group B,(0.07±0.055) vs (0.71 ±0.029),P＜0.05; group E compared with group C,(0.15±0.038) vs (0.65±0.026).Conclusion RPRD may alleviate the pathologic changes in AP

Objective To construct the eukaryotic expression vector of Notch1intracellular domain,p3XFLAG?CMV7?NICD1,so as to prepare for the further research and exploration of effect of Notch1 on promoting epithelial?mesenchymal transition of human lens epithelial cells. Methods The cDNA fragment was reversely transcribed by RT?PCR from total RNA extracted from the SRA01/04 cells and was encoded with the specific am?plification?targeted NICD1was obtained from the SRA01/04 cells,then the cDNA fragment was inserted into p3XFLAG?CMV7 to transcribe Esche?richia coli DH5α. And the recombinant plasmid was extracted after bacterial screening by LB plating medium and confirmed by the restriction endo?nuclease digestion and DNA sequencing. Results The target gene obtained had the same molecular size as predicted. It was indicated that recom?bined p3XFLAG?CMV7 plasmid contained correct recombinant human Notch1 sequences and p3XFLAG?CMV7?NICD1 was constructed success?fully. The western blotting showed protein NICD1 expressed in SRA01/04 cells transfected with p3XFLAG?CMV7?NICD1. Conclusion The suc?cessful construction of p3XFLAG?CMV7?NICD1 will provide a foundation for a further study studies in on the effect relationship of Notch signaling pathway and in posterior capsular opacification(PCO)after cataract extraction.

Objective To study the radiosensitization effects of tetrandrine on advanced non small cell lung cancer and its toxicity.Methods The patients of 82 cases with advanced non-small cell lung cancer were confirmed by pathology or cytology.The first course of treatment was treated with radiation therapy.Patients were divided into three groups:tetrandrine group,paclitaxel group and radiotherapy group.Tetrandrine group(30 cases)took radiotherapy with 40 mg tetrandrine(3 times a day)from the first day to the ending.Paclitaxel group (29 cases)took radiotherapy with intravenous infusion of 60 mg paclitaxel(once a week).Radio-therapy group (23 cases)only received radiotherapy.Results Tetrandrine and paclitaxel had the same radiosensitizing effect in ra-diotherapy.The total effective rate of tetrandrine and paclitaxel group was higher than radiotherapy group (P <0.05 ).The inci-dence of radiation pneumonitis in tetrandrine group was significantly lower than the other two groups (P <0.05).The one year free disease survival rate was promoted in tetrandrine group than other groups.Conclusion Tetrandrine was known as the same radia-tion sensitizing effect of paclitaxel fairly,which can reduce the toxicity of radiotherapy.
