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.

Transrectal ultrasonography is one of the early diagnostic approaches of prostate cancer.In this article,the recent study progression of conventional transrectal ultrasonography with combination of new techniques,such as contrast-enhanced ultrasonography,elastography,image fusion,and so on,in diagnosis of prostate cancer was summarized on the basis of a review of the literatures.

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.

Objective To observe the effect of bronchial asthma in rats treated by Chuanzhuping,a prescription which has the function of dispersing lung Qi and invigorating spleen Qi,and explore its possible mechanism.Method Thirty-two male Wistar rats of SPF level were divided into four groups randomly:control group(A),asthma group(B),Dexamethasone group(C) and Xiaozhuping group(D).Except group A,the others were established animal model of asthma.After drawing materials,hematoxylin and eosin(HE) staining were performed.The pathological changes in bronchopulmonary tissue of rats were detected.The basementmembrane perimeter(Pbm),the airwaywall area(Wat) and the smooth musclewall area(Wam) were measured and calculated by using image analysis system.The concentration of transforming growth factor-?1(TGF-?1) in bronchopulmonary tissue was observed by immunohistochemical method and the integral optical density(IOD values) of it was measured.Results In bronchopulmonary tissue of group B,Wat,Wam and the concentration of TGF-?1 increased,and were significantly different from that in group A(P0.05).In group D,the concentration of TGF-?1 decreased and was significantly different from that in group C(P

Objective To explore the clinical significance of interstitial chemotherapy applied in breast cancer.Methods Sixty breast cancer patients with modified radical mastectomy were divided into treatment group (40 cases) and control group (20 cases) according to whether using fluorouracil implants.The control group was given conventional treatment.In treatment group,distilled water washed the wound after conventional treatment,and fluorouracil implants (0.4 g) was placed below local tumor,between pectoralis major and pectoralis minor,below 0.5 cm axillary vessel.The bone marrow suppression,liver and renal function,gastrointestinal reaction,skin flap necrosis,subcutaeous hydrops,local recurrence were observed in the 2 groups.Results There were no significant differences in the rates of bone marrow suppression,liver and renal function abnormal,skin flap necrosis,subcutaeous hydrops and gastrointestinal reaction between treatment group and control group (P ＞ 0.05).The rate of local recurrence in treatment group was significantly lower than that in control group [0 vs.20.0％ (4/20)],there was statistical difference (P ＜0.05).Conclusion Intraoperative application of fluorouracil implants is safe and effective in modified radical mastectomy of breast cancer.

0.05) in blood serum creatinine,urea nitrogen,and endogenous creatinine clearance rate between before and after using vancomycin in 65 old patients.Conclusions Mostly it is safely using the vancomycin in old patients.It can be increased in the security and validity according to endogenous creatinine clearance rate and measuration of blood drug concentration when used vancomycin.Individualization for usage of the vancomycin is helpful.

To investigate the clinical effect of tonifying the kidney and promoting blood circulation to promote oocyte decoction in the treatment of anovulatory infertility caused by polycystic ovary syndrome. Sixty cases were selected from the out-patient department of Xiyuan hospital of China academy of Chinese medical sciences and the Chinese academy of traditional Chinese medicine, Chinese medicine out-patient department. Sixty patients with PCOS patients were randomly divided into the treatment group and the control group, with 30 cases and 30 cases respectively. The treatment group was given decoction of the reinforcing kidney, activating blood circulation and ovarian stimulation compound recipe. The control group was treated with clomiphene. Through the treatment of 1-2 courses, in the treatment group the pregnancy rate was 56.67%, the ovulation rate 61%; in control group of clomiphene citrate ovulation ratepregnancy rate was 30% , 72.84% of ovulation rate. The difference was significant between two groups (P < 0.05), the pregnancy rate in the treatment group was higher than the control group. The treatment group has regulatory effect on FSH, LH and their ratio, and increase E2 level, decrease T, PRL, INS and other hormone levels, contributing to the mature development of the follicles and endometrium growth, increase the ovulation rate and pregnancy rate. The control group on FSH, E2 increased, LH, T, PRL and INS showed no obvious effect.
