Discussion on legislation of brain death criteria in China from the perspective of organ donation / 器官移植

In recent years, organ donation has developed rapidly in China, whereas the brain death criteria have not been confirmed by relevant legislation. In this article, the current legislation situation of brain death criteria at home and abroad, and the current criteria for determination of death for organ donation after citizen's death in China were introduced. The necessity of legislation of brain death criteria in China was discussed from the perspective of organ donation, and suggestions on the form and content of brain death criteria legislation were proposed based on the actual national conditions, aiming to provide reference for the legislation of brain death criteria.

Research progress of regulatory effects of water-soluble compounds isolated form Salvia miltiorrhiza on bone metabolism / 中国药理学通报

Salvia miltiorrhiza is a traditional Chinese medicine for the treatment of cardiovascular diseases .Recently, increasing evidence demonstrates that the water-soluble compounds isolated from Salvia miltiorrhiza,including tanshinol and salvianolic acid B, exert a regulatory influence on bone metabolism .The under-lying mechanism of these compounds involves various pathways , such as Wnt/β-catenin, ERK, BMP, OPG/RANKL/RANK and FoxO mediated oxidative stress pathway .This paper reviews pre-vious effects and mechanism of polyphenolic acids in Salvia milt-iorrhiza , which may provide the base for the research and devel-opment of the new agents to treat osteoporosis .

Research progress of anti-osteoporotic effects of genistein / 中国药理学通报

Genistein, as one kind of phytoestrogens, can stimu-late osteoblastic proliferation, differention and mineralization, and can also inhibit bone resorption activity of osteoclast. The effect of genistein on bone metabolism lies in various molecular mechanisms. This paper reviews the research progress of the an-ti-osteoporotic action of genistein and its mechanism, which may provide a basis for the research and development of new agents to treat osteoporosis.

FoxOs and osteoporosis / 中国药理学通报

As one subclass of forkhead proteins, the forkhead box O ( FoxO) transcription factors take part in a series of bio-logical processes including cellular apoptosis, damaged DNA re-pair and cleavage of reactive oxygen species(ROS). Increasing evidence highlights that oxidative stress elicited by FoxOs con-tributes to imbalance of redox status in cells related to bone me-tabolism, resulting in development of the pathogenesis of osteo-porosis. This article reviews the relationship of FoxOs and osteo-porosis, which may be beneficial for the research of pathological mechanism and therapeutic strategy of osteoporosis.

Analysis on correlation between menarche age and metabolic syndrome among natural menopausal women in an area of Jiangsu province / 重庆医学

Objective To explore the correlation between menarche age and metabolisyndrome (MS) in natural menopause women .MethodThree thousand two hundred and founatural menopausal women aged 45-64 yearold were selected from 7 ad-ministrative villagein Taixing areand performed the questionnaire investigation ,physical measurementand biochemical test. The respondentwere divided into differengroupof lesthan 14 yearold ,15-16 yearold and more than 17 yearold according to the menarche age .The Mdiagnostistandard by the International DiabeteFederation (IDF ,2005) and the modified diagnostistandard based on the Asian by the third treatmenreporof the national cholesterol education program adultreatmengroup (NCEP ATPⅢ ,2005) were adopted and the Logistiregression analysiwaused foanalyzing the correlation between menarche age and M.ResultThe Mcrude prevalence rate in thigroup wa35 .39% (IDF ,2005) and 20 .57% (NCEP ATP Ⅲ ,2005);the Logistiregression analysishowed thathe conclusion by the two kindof Mdiagnostistandard waconsisten,I .e .earliemenarche age (lesthan 14 yearold) increased the Moccurrence[aftemultivariable adjusting OR=1 .41(1 .10-1 .82) and 1 .55 (1 .16-2 .08)] ,in addition ,earliemenarche age also significantly increased the central obesity risk in women ,while latemenarche age (＞16 yearold) had no correlation with M.Conclusion The earliemenarche age irisk factoof M.So the health publici-ty and education ,prevention and control on the menopausal women with earliemenarche age should be strengthened .

An epidemiological survey of metabolic syndrome in natural post-menopausal women aged 45-64 years in Taixing area, Jiangsu province / 中华内分泌代谢杂志

Objective To determine the prevalence of metabolic syndrome ( MS) in women who had gone through natural menopause, and to provide basic data for developing effective prevention and intervention of metabolic syndrome in Taixing area Jiangsu province. Methods A cluster sample of natural postmenopausal women aged 45 to 64 years were sampled and assessed by questionnaires, physical measurements, and biochemical tests; and analyzed according to the International Diabetes Federation ( IDF, 2005) diagnostic criteria for MS. Results The crude prevalence of metabolic syndrome was 35. 25% and the standardized prevalence rate was 31. 47% after age being adjusted. The prevalence of metabolic syndrome was increased with age ( P < 0. 01). The constituent ratio of the combinations of 3, 4, and 5 components in MS was 21. 45% , 10. 73% , and 3. 07% , respectively. Conclusion The prevalence of the metabolic syndrome among older women after menopause is high and increasing with aging. Public education should be strengthened to improve the quality of life in postmenopausal women and prevention and intervention should be adopted earlier as well.

Siraitia grosvenori and rehmannia glutinosa promote the hematopoietic stem cells and progenitor cells proliferation and function / 中国比较医学杂志

Objective To investigate the influence of Siraitia Grosvenori and Rehmannia Glutinosa on the Hematopoietic stem cells proliferation and function .Methods Cells from the peripheral blood , spleen and bone marrow of mice were stained with indicated antibodies , and analyzed by flow cytometry .Mice were divided 3 groups:control group, Siraitia Grosvenori treatment group and Rehmannia Glutinosa treatment group .After 4.5Gy IR treatment, mice divided 4 groups: control group, 4.5Gy IR treatment and feed with normal food, 4.5Gy IR treatment and feed with Siraitia Grosvenori and 4.5Gy IR treatment and feed with Rehmannia Glutinosa for 1 month.Results Mice fed with Siraitia Grosvenori and Rehmannia Glutinosa decreased the percentage of B cells and increased the percentage of M cell .For HSCs, the number of HSCs was increased , especially the number of LT-HSCs.After 4.5Gy IR treatment, mice fed with Siraitia Grosvenori and Rehmannia Glutinosa increase the number of HSCs , and increased the percentage of M cells . Conclusion Siraitia Grosvenori and Rehmannia Glutinosa promote the hematopoietic stem cells and progenitor cells proliferation and function and recover the damage that caused by IR treatment .

IL-33 transgenic mice increase the myeloid differentiation in hematopoietic stem cells / 中国比较医学杂志

Objective To study the influence of IL-33 on the Hematopoietic stem cells and progenitor cells . Methods Cells from the peripheral blood , spleen, thymus and bone marrow were stained with indicated antibodies and analyzed by flow cytometry . The LT-HSCs were sorted and culture using in vitro clonogenic assay . Results The percentage of B cells and T cells was decreased and the percentage of M cells was increased in the peripheral blood from IL -33 transgenic mice .Compared with the wildtype mice , the number of HSCs , MPPs and CLP was decreased;meanwhile the number of CMP and GMP was increased in the bone marrow from IL-33 transgenic mice .An in vitro clonogenic assay showed that LT-HSCs increased the ability to self-renew from IL-33 transgenic mice .And the percentage of S-G2-M stage hematopoietic stem cell was increased from IL-33 transgenic mice .Conclusion IL-33 increase the myeloid differentiation in hematopoietic stem cells .
