Objective This study was to explore a justifiable approach for the translation of traditional Chinese medicine (TCM) terms in the light of Skopos Theory and thus to provide references to the standardization of TCM terms.Methods By exploring the source and development of a TCM term Bi,we studied its connotation,compared available English versions and decided on the choice version.Results The word arthralgia,obstruction or impediment was found to be the most frequently used word in 12 recognized publications,more frequent than the transliteration of Bi.Conclusion It is suggested that an accurate and a complete understanding of TCM terms and English expressions are required prior to translating so that the faithfulness and accuracy of the translation are maintained for the sake of optimal approximation.

Objective To explore the effects of estrogen and angiotensin Ⅱ receptor 1 inhibitor（saralasin）on cell proliferation,cell cycle and apoptosis in endometrial carcinoma cell line HEC-1A.Methods Immunocytochemical assay was applied to detect the expression of AT1-R,PI3K,p-Akt and ERK protein in HEC-1A cell.The effects of estrogen and saralasin on cell proliferation,cell cycle distribution and apoptosis of HEC-1A cell were detected by MTT assay and fluorescence activated cell sorting technique.The expression of ERK and p-Akt protein in HEC-1A cell treated with estrogen and saralasin were analyzed by Western blot.Results The expression of AT1-R,PI3K,pAkt,and ERK protein was found in HEC-1A cell.Estrogen stimulated the proliferation of HEC-1A cell,decreased G0~G1 phase proportion and increased S phase proportion significantly,minimized the number of apoptotic cells,and up-regulated the expression of ERK protein.Saralasin obviously inhibited the proliferation and induced apoptosis of estrogen induced HEC-1A cell,increased G0~G1 phase proportion and decreased S phase proportion,and down-regulated the expression of ERK protein.Conclusion Estrogen could promote the proliferation of HEC-1A cell through AT1-R.AT1-R inhibitor saralasin could inhibit the proliferation and induce the apoptosis of estrogen induced HEC-1A cell.The down-regulation of ERK protein expression by interrupting the mitogen-activated protein kinase（MAPK）signaling pathway might be involved in the possible mechanism.Thus saralasin could be a valid approach to treat ER-negative endometrial carcinoma.

Quality control of traditional Chinese medicine (TCM) has become bottlenecks of TCM industry devel-opment and TCM international recognition. To solve the retational problems, we explored the establishment of new quality control method based on efficacy and safety. Firstly, material basis of TCM efficacy was investigated deeply and systematically. Then, quality control method based on efficacy was established by using active ingre-dients as markers. We also establish detection methods based on safety, such as pesticide residues, heavy metals and harmful elements , mycotoxins .

Objective To evaluate the reproducibility of quality intima-media thickness(QIMT) and quality arterial stiffness (QAS) technique in assessment of carotid under different measuring methods.Methods Between December 2012 and January 2014,carotid QIMT and QAS examinations were carried out in 30 health volunteers.QIMT and QAS indicators included IMT in QIMT and distensibility coefficient (DC),compliance coefficient(CC),stiffness index α(α),stiffness index β(β),pulse wave velocity(PWV) in QAS.The measurement employed unilateral/once,bilateral/twice,and unilateral/twice methods.Using intra observer and inter-observer variability,the reproducibility was compared between different QIMT and QAS indicators and measuring methods.Results Extremely high level of intra-observer reproducibility was found for both QIMT and QAS technique (ICC＞0.8).QIMT also showed an excellent inter observer reproducibility (ICC＞0.8).In contrast,the reproducibility of QAS technique varied in different indicators (PWV ＞ β ≈ α ＞ CC ＞ DC) and method ( unilateral/once ＞ bilateral/twice ＞ unilateral/twice).Conclusions QIMT measurement was highly reproducible.Whereas the reproducibility of QAS technique varied in different indicators and methods.Due to low reproducibility,the study result did not support the clinical application of DC indicator and unilateral/once method.
