BACKGROUND:Studies regarding neural stem cells (NSCs) mainly focus on rodents and human,few of which addressing non-human primate animals.OBJECTIVE:To explore a culture system of cynomolgus monkey NSCs (cmNSCs),additionally,to observe its differential potential.DESIGN,TIME AND SETTING:An in vitro cytology observation was performed at the Canter for Stem Cell Biology and Tissue Engineering,Sun Yat-sen University between July 2008 and April 2009.MATERIALS:Spontaneously aborted cynomolgus monkey fetus with 3-5 months old (gestational age),was provided by Landao Biotechnology Co.,Ltd.METHODS:The subventricular zone and the hippocampus were dissected aseptically from the brain of spontaneously aborted cynomolgus monkey fetus,then triturated with fire-polished glass Pasteur pipettes to single cells,and cultured in 25 cm~2 culture flask with concentration of (2.0-5.0)×10~5.The neurospheres were transferred into polyornithine and fibronectin precoated cell culture dish after 2 weeks when they formed.Each 20 μg/L of epithelium growth factor (EGF) and basic fibroblast growth factor (bFGF) was daily added.The adhesive cells were passagad when they reached about 90% confluency.MAIN OUTCOME MEASURES:The NSCs and its differential potential were identified by surface marker nestin and immunocytochemistry.RESULTS:The neurospheres formed after 1 week culture,and grew with time prolonged.The culture system was changed into adherent culture at 4th week.At 24 hours after plated on the poly-omithine/fibronectin pre-coated dish,neurospheras adhered to the dish and many cells migrated out of neurnshperes and proliferated as monolayer.The immunocytochemistry showed that NSCs which culture medium contain EGF and bFGF preserve neatin positive,and the cmNSCs that without EGF and bFGF differentiated into astrocytes (GFAP positive),neurons (Tuj-1 positive) and oligodendrocytes (O4 positive).CONCLUSION:The culture system which combines suspension culture and adherent culture is fit for the culture of cmNSCs.The cultured cmNSCs has potential to differentiate into astrocytes,neuronal cells and oligodendrocytes.

Aim To investigate the effect of acteoside (AS)on the expression of caspase-3 in cerebral cortex of mouse models of Alzheimer’s disease(AD).Meth-ods Kunming (KM)strain mice were assigned into control group,model group,positive control group (VitE)and acteoside group.Every group was induced by a combination of D-galactose(i.p.60mg·kg -1 · d -1 )and AlCl3 (i.g.5mg·kg -1 ·d -1 )for 60ds ex-cept for control group,then mice were treated by dif-ferent concentrations(30,60,1 20 mg·kg -1 ·d -1 )of acteoside for 30ds.During the time,mice were in-duced continuously by a combination of D-galactose and AlCl3 .The learning and memory of mice were de-tected by step-down test,the activity of AChE in serum and brain of mice was measured by chemical colorime-try,the structure changes in cerebral cortex were ob-served by HE staining,and the expression of caspase-3 in cerebral cortex was analyzed through the immunohis-tochemical staining.Results Compared with model group,acteoside could improve the learning and mem-ory abilities(P <0.05 or P <0.01 ),decrease the ac-tivity of AChE in serum and brain(P <0.05 or P <0.01 ),and improve the morphology and number of neuron in cerebral cortex(P <0.01 ).Moreover,acte-oside could significantly inhibit the expression of caspase-3 in cerebral cortex (P <0.05,P <0.01 ). Conclusion Acteoside has significantly protective effects on brain damage of mice induced by a combina-tion of D-galactose and AlCl3 , and it′s protective mechanism probably relate to inhibiting the expression of caspase-3 and maintainings the normal morphology and number of neuron in cerebral cortex.

Objective To investigate the effect of acteoside on injury PC12 cells induced by glutamate. Methods PC12 cells were assigned into normal control group, model control group, positive drug group and acteoside(AS) treated group. Every group was treated by 1. 5 mmol·L-1 glutamate for 24 hours except for the control group, and the injury was antagonized by 10 μmol·L-1 Vit E and acteoside at different concentration(15. 625, 31. 25, 62. 5, 125 and 250 μmol·L-1 ). Cell morphology was observed by inverted microscope, cell survival was determined with MTT, LDH activity was measured by enzyme label kit, the MDA content and SOD activity were measured by TBA kit and WST kit, and the ROS was measured by Elisa kit. Results Compared with the model control group, all doses of acteoside could significantly improve the PC12 cell morphology and survival (P<0. 05), inhibit LDH activity and production of MDA and ROS (P<0. 05), increase the activity of SOD (P<0. 05), except for the lowest dose group. Conclusion Acteoside has protective effects on PC12 cells injured by glutamate.

Objective To investigate the effect of Galangin of different purity on melanocyte proliferation and melanin synthesis of A375-HaCaT co-culture system. Methods The A375-HaCaT co-culture system was established with Transwell technology, and 0.1, 0.5, 1.0, 5.0, 10 μg/mL Galangin of the purity of 70%and 90%was used to act on the co-culture system. Cell proliferation, melanin content and tyrosinase of A375 were measured by MTT assay, NaOH lysis assay and L-DOPA oxidation assay respectively. The cytokines such as ET-1 and SCF in HaCaT were detected by ELISA. Results A375 cells in co-culture system grew well, and 0.1, 0.5, 1.0, 5.0, 10 μg/mL Galangin of the purity of 70% and 90% had up-regulation effect on cell proliferation, melanin content and tyrosinase of A375. Moreover, Galangin could increase the expression level of ET-1 and SCF of HaCaT at more than 0.5 μg/mL, and the effect of Galangin of 70% purity was better than 90% purity. Conclusion Galangin could promote the cell proliferation, melanin content and tyrosinase of A375, and mechanism of the pathways is probably related to the up-regulation on the expression of ET-1 and SCF of HaCaT.

Objective To investigate the utility of serum prostate specific antigen(PSA) density (PSAD),prostate antigen transition zone density(PSAT) and the ratio of free/total PSA with PSAD [(F/T)/PSAD] in the diagnosis of prostatic carcinoma (PCa) by three-dimensional ultrasonography.Methods Seventy-eight patients (serum prostate-specific antigen between 4-20 μg/L ) were involved.The prostatic volume and its transition zone volume were measured by three-dimensional ultrasonography.Then the relative parameters of PSA [PSAD,PSAT and (F/T)/PSAD] were calculated.Pathologic types were determined by using needle biopsy of prostate.Results Among them,27 patients were suffering from PCa,while the other 51 benign prostate hypertrophy (BPH).The difference of PSAD,PSAT and (F/T)/PSAD between PCa and BPH had arrived statistical significance (P<0.05).Proportions under the PCa curves were 0.736,0.760,0.800 respectively.Considering both sensitivity and specificity,a cutoff was recommanded:PSAD>0.20,PSAT>0.33,(F/T)/PSAD<0.8.Conclusions When the serum PSA level is between 4 μg/L and 20 μg/L,PSAD,PSAT and (F/T)/PSAD are of significant value to differentiate PCa from benign prostatic hyperplasia patients.The data are more reliable if prostatic volume are calculated by three-dimensional transrectal ultrasonography.

Objective To investigate the roles of hemopoietic stem cells (HSCs) in the pathogenesis of psoriasis. Methods HSCs were isolated from the bone marrow of a patient with psoriasis vulgaris and a normal human control. Forward- and reverse-subtracted cDNA libraries were constructed by using suppression subtractive hybridization (SSH) technique between HSCs from the patient and control. Bacterial PCR and dot hybridization were performed to screen for positive clones followed by gene sequencing, identification and functional analysis. Real time quantitative PCR was carried out to measure the mRNA expression of interferon-γ and thymosin 10 (TMSB10). Results Nine genes were screened from the forward-subtracted cDNA library which encoded interferon-γ, tyrosine phosphatase, SUMO1 activase, etc, and 8 genes including the TMSB10-encoding gene were screened from the reverse-subtracted cDNA library. The relative expression level of interferon-γ in HSCs from the patient was 47.5 times that in HSCs from the control, while the level of TMSB10 from the control was 22.6 times that from the patient. Conclusion The abnormal expression of 17 genes which encode interferon-γ, thyrosin, and so on, may be involved in the development of psoriasis.

Objective To discuss the clinical application of laparoscopic ultrasound (LUS) in laparoscopic nephron sparing surgery(NSS) for central renal tumors.Methods Eighteen patients underwent laparoscopic NSS for central renal tumors.The use of LUS was mainly lay in observing the nature and size of the tumor, the minimum distance from the tumor to capsule, collective system and renal artery, tumor's vasa vasorum,tumor localization and determination of margins.Results Of the 18 central renal tumors,the size was 11 - 29 mm,23.3 mm in average.The minimum distance from the tumor to capsule was 2 - 11mm,4.7 mm in average.The minimum distance within 5 mm to collective system and to capsule was 12 and 10 cases respectively.The tumor was surrounded by nephridial tissue completely on LUS, without protruding capsule.LUS diagnosis of 18 central renal tumors: 10 cases of renal angiomyolipoma,7 cases of renal cell carcinoma, 1 case of renal cyst with capsule wall calcification (at first diagnosed as renal carcinoma by CT).The findings of LUS were same to pathologic and(or) postoperative diagnoses.The accuracy of ultrasound localization was 100％.The surgical margins of 7 cases of renal cell carcinoma were all negative.Conclusions It is of high clinical value of LUS on locating the tumor and defining tumor margins in laparoscopic resection of central renal tumors.Besides, more information on tumor and vessel supply will be achieved.
