OBJECTIVETo investigate the chemical constituents from the tuber of the planted Cremastra appendiculata.

METHODThe compounds were isolated by column chromatography over silica gel, Sephadex LH-20 and RP-HPLC, and their structures were elucidated on the basis of spectroscopic analysis.

RESULTEight compounds were isolated, and identified as cirrhopetalanthrin (I), 7-hydroxy-4-methoxyphenanthrene-2-O-beta-D-glucoside (II), 4-(2-hydroxyethyl)-2-methoxyphenyl-1-O-beta-D-glucopyranoside (III), tyrosol 8-O-beta-D-gluco-pyranoside (IV), vanilloloside (V), p-hydroxybenzaldehyde (VI), sucrose (VII), adenosine (VIII).

CONCLUSIONThese compounds are isolated from this plant for the first time. All compounds were evaluated against human colon cancer (HCT-8), human hepatoma (Bel7402), human stomach cancer(BGC-823), human lung adenocarcinoma (A549), human breast cancer (MCF-7), and human ovarian cancer (A2780) cell lines, and cirrhopetalanthrin (I) showed non-selective moderate cytotoxicity with IC50 values of 8.4-13.3 micromol x L(-1), and other compounds were inactive.

OBJECTIVETo study the chemical constituents of the corm of the planted Cremastra appendiculata.

METHODThe compounds were isolated by column chromatography with silica gel and Sephadex LH-20, and their structures were elucidated by means of spectroscopic methods including 2D NMR techniques.

RESULTSix compounds were isolated, and identified as isohircinol (I), flavanthrinin (II), p-hydroxyphenylethyl alcohol (III), 3,4-dihydroxyphenylethyl alcohol (IV), daucosterol (V), beta-sitosterol (VI).

CONCLUSIONThese compounds were not previously isolated from this plant, and isohircinol (I) was obtained from natural source for the first time.

PURPOSE: G-protein coupled estrogen receptor 1 (GPER) probably play important roles in the progression of breast cancer including endocrine therapeutic resistance. We evaluated GPER in primary breast cancers. METHODS: Immunohistochemistry was used to detect GPER in paraffin-embedded tissues of primary breast cancers from 423 patients and GPER expression was correlated with clinicopathological factors. RESULTS: GPER was expressed in 63.8% of specimens, coexpressed with estrogen receptor alpha (ERalpha) in 36.6% of tumors and was positive in 62.5% of the ERalpha-negative tumors. The expression of GPER had no relationship with the status of ERalpha, progesterone receptor and HER2. Although the expression of GPER was significantly inversely related with nodal status (p=0.045), no correlation between GPER expression and other clinicopathological variables (age, menstruation status, tumor size, stage, histologic grade, Nottingham Prognostic Index or pathological type) was found. CONCLUSION: GPER and ERalpha exhibited independent expression pattern of distribution in primary breast cancers. A long-term follow-up and a more definite molecular phenotype for ER are necessary in confirming studies.

Objective To use World Health Organization Family International Classifications (WHO-FICs) to explore the framework and approaches of development and research of guidelines of rehabilitation at levels of policies, community and services.Methods The important documents and tools of rehabilitation at international level, including United Nations Convention on the Rights of Persons with Disabilities, WHO World Report on Disability, Community-based Rehabilitation Guideline, Rehabilitation in Health Service System, and International Classification of Diseases (ICD), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHI) of WHO-FICs, had been discussed.Results The framework, classifications, diagnosis and description of diseases and functioning, coding, intervention and functioning evaluation based on ICD-11, ICF and ICHI-β-2 had been established for development and implementation of rehabilitation guidelines and Cochrane rehabilitation.Conclusion The framework and systematic approaches of ontology, classification, terminology, coding, diagnosis and description of diseases and functioning, interventions and evaluations for the development and implementation of rehabilitation guidelines had been developed.
