Objective To study the chemical constituents in the stem of Acanthus ilicifolius.Methods Some compounds were repeatedly isolated and purified on silica gel column chromatography and vacuum liquid chromatography,their chemical structures were elucidated by their physicochemical properties and spectral data,such as IR,(()~1HNMR),(()~(13)C-NMR),and ESI-MS.Results Eight compounds were obtained from the stem of A.ilicifolius and identified as hexacosanoic acid(Ⅰ),stigmasterol(Ⅱ),tetratriacontanol(Ⅲ), 2-benzoxazolinone(Ⅳ),stigmasterol-3-O-?-D-glucopyranoiside(Ⅴ),vanillic acid(Ⅵ),4-hydroxy-2-benzoxazolone(Ⅶ),quercetin(Ⅷ).Conclusion Compound Ⅶ is first reported as a natural product.Compounds Ⅰ,Ⅲ,and Ⅵ-Ⅶ are reported from this plant for the first time.

As an important basic industry group of health industry,health management provided beneficial development environment for health management industry,which had important significance on improving the development of the whole health industry.It analyzed the development trend of domestic and foreign health management industry and the current problems of the health management industry development in China.The development strategies of health management industry in China were discussed from guarantee mechanism,system construction,new mood development,improving the elements,health and culture training,payment mechanism innovation and exploring the characteristics.

Social capital has become an important service provider of medical and health undertakings in China.Its active participation in health management industry services promotes the overall development of China's health industry.The paper discusses the four important roles of social capital in health management industry,and puts forward four development strategies,including the transformation to the high-end health management services,and undertaking basic health management services and public and private health management of the joint venture and the development of specialized health management service.

Objective To evaluate the feasibility of cell free fetal DNA(cffDNA)-based noninvasive prenatal diagnosis,we developed a precise technique for fetal sex determining region of Y chromosome(SRY)gene detection using size-fractionated cell-free DNA in maternal plasma.Methods Peripheral blood samples were collected form 117 pregnant women.cffDNA was extracted based on a column absorbent method and isolated by agarose gel electrophoresis.A dulex-polymerase chain reaction(PCR)was used to detected SRY gene and glycerol-dehyde-phosphate dehydrogenase(GAPDH)gene.Results Both SRY and GAPDH gene were detected in 86 cffDNA samples from women bearing male fetuses.And only GAPDH gene was detected in 71 cffDNA samples from women bearing female fetuses.These results had a coincidence whit those of villus or amniotic fluid samples.The specificity and sensitivity reached 100%(117/117)and 100%(66/66),respectively.Conclusion By agarose gel electrophoresis,re-extratedand and dulex PCR,size-fractionated cell-free fetal DNA in maternal plasma can be selective enriched and used to noninvasive prenatal diagnosis of sex-linked disorders and single gene disorders.

Extramedullary plasmacytoma (EMP) are often located in the head and neck region, commonly affecting the nasal cavity, tonsillar fossa and oral cavity but rarely the retropharyngeal space. In this report, a 60-year-old woman with large EMP in the retropharyngeal space is presented, who was diagnosed by pathology, bone marrow aspirate and computed tomography scan. The patient received operation and postoperative radiotherapy with dose of 50 Gy. At sixteen months follow-up, the patient was doing well with no signs of recurrence.

Objective:To investigate the effects of TGF-? 1 and TGF-? 2 on cleft palate formation .Methods:30 pregnant NIH mice in experimental group were injected with dexamethasone (50 mg/kg) intr aperitoneally in GD 12 12 ,30 mice in control group were given the same vo lume of NS.Fetuses were removed out in GD13 12 ,GD14 12 and GD15 12 , heads of the mice were sliced in coronal plane.Expression of TGF-? 1 an d TGF-? 2 in embryonic palate were detected by immunohistochemical methods: Results:Dexamethasone (50 mg/kg) induced cleft palate in NI H embryos,and expression of TGF-? 1 and TGF-? 2 in palate tissues was h igher in the experimental group than that in the control (P
