BACKGRoUND:Endothelial basal medium is mainly used to culture endothelial progenitor cells.Studies on mesenchymal stem cells (MSCs) cultured in this medium are few. OBJECTIVE:To compare the outcome of MSCs cultured in different mediums including endothelial basal medium. DESiGN.TIME AND SETTING:The control eell experiment was performed at the Muniopal Key Laboratory of Xinhua Hospital of Shanghai.China from September 2005 to May 2006. MATERIALS:Eight pregnant mongrel dogs were selected to obtain umbilical cord blood for isolation and culture of stem cells. Endothelial eell basal medium and endothelial cell medium were bought from Clonetics.USA.Mouse anti-CDlla monoclonal andbody,mouse anti-CDllb monoclonal antibody.mouse anti-CD29 monoclenal antibody and mouse anti-CD7l monoclonal antibody Were purchased from Antibody diagnostica,USA.Mouse anti-CD34 monoclonal antibody was obtained from Lab Vision Corporation.USA.METHODS:Umbilical cord blood stem cells were divided into four groups.Umbilical cord blood steTn cells in the group A were incubated in the endothellal basal medium.Umbilical cord blood steHl cells in the group B were incubated in the endothelial basal medium containing microvascular endothelial cells in a 6-well plate.Umbilical cord blood stem cells in the group C were incubated in the endothelial basal medium containing endotheliaI medium in a 6-well plate coated with fibronectin.Umbilical cord blood stelrn cells in the group D were incubated in the endothelial basal medium containing endothelial medium in a 25 cm2 ctdturing flask.MAIN OUTCOME MEASURES:Cell morphology and population doublings were observed.CDlla,CDllb,CD34,CD29 and CD71 expression was detected by immunohistochemistry. RESULTS:Fibroblast-like cells were measured in each group.The celIs grew badly in morphology and proliferated slowly in the group A,while cells proliferated rapidlyinthe group B.The cell clones were instable and inclined to aging in the group C,with a new cell clone was found.The cells in the group D were similar to those in the group C.Surface antigens detected by immunohistochemistry showed CDlla(-),CDllb(-),CD34(-),CD29(+)and CD7l(+). CONCLUSION:MSCs witll well growth and rapid proliferation can be detected in the endothelial basal medium containing endothellal medium in an intact 6-well plate.The outcome is bad in fibronectm-coated plate or 25 cm2 culture flask.

Objective: To prepare plumbagin transfersomal (PBG-T) gel and investigate its transdermal penetration characteristics in vitro. Methods: Plumbagin transfersomes were prepared by film-ultrasonic dispersion method. The optimal prescription condition of PBG-T was selected by central composite design and response surface method. The formula of PBG-T gel was optimized by orthogonal test. The Franz diffusion cell was used to investigate transdermal penetration characteristics of PBG-T gel in vitro. Results: The optimal prescription condition of transfersomes was determined as drug 10.0 mg, phospholipids 700.0 mg, Tween-80 91.5 mg, ultrasonication time 13 min. The optimal prescription condition of transfersomal gel was 1% carbomer 940 as gel matrix, and 5% glycerol as the humectant. According to the optimized prescription, the entrapment efficiency, the mean particle size, and Zeta potential of PBG-T were (79.88 ± 2.26)%, (125.64 ± 4.54) nm, and (-30.97 ± 1.13) mV. The cumulative penetration rate of PBG-T gel was 70.0% at 12 h. Conclusion: The optimal preparation technique is stable and feasible. Transfersomal gel features a sustained release in vitro, the transfersomal gel can increase penetration rate of plumbagin through the skin of rats.

OBJECTIVEIn this study, the clinical data of 240 cases of data acquisition on ovulation in patients with anovulatory infertility.

METHODUsing the method of factor analysis, summed up the distribution situation of various syndromes and the relationship of disease-syndrome-symptom.

RESULTFrom the study we found that polycystic ocary syndrome > premature ovarian failure > corpus luteum insufficiency > luteinized unruptured follicle syndrome > hyperprolactinemia > anovulatory dysfunctional uterine bleeding. Using the factor analysis method, the syndromes of anovulatory infertility were divided into six types and the distribution proportion of them is: kidney Yang deficiency and blood stasis > kidney Yang deficiency > kidney Yin deficiency and blood stasis > kidney Yin deficiency and liver Qi stagnation syndrome > kidney Yang deficiency and phlegm dampness stagnation > kidney Yin deficiency. By means of statistics, the traditional Chinese medicine (TCM) symptoms as abdomen pain before menstrual onset, obfuscation colour, cold lower abdomen, insomnia, fatigue, eyes dark, face dark or ring lip dark, before and after menstruation breast swelling, chest tightness, irritable insomnia, depression and lower abdomen pain during menstruation etc contribute high degree in the process.

CONCLUSIONPolycystic ovary syndrome and premature are the main causes of ovulatory disorder infertility and the disease incidence rate assumed the tendency which rose year by year. The treatment of the disease of kidney yang deficiency syndrome scales biggest the disease degree of contribution. Blood stasis is the important factor in the process of pathogenesis evolution. In the study of disease distribution, we found that symptom distribution trend roughly the same and the same symptom severity in different diseases with different, which provides experience for the theory-different diseases with the same therapeutic method. These conclusions provide guidance and reference evidences for clinic practice.
