3.Research on Suicide Attempts and Suicide Attitude Status of Medical University Undergraduates-to Take Kunming Medical University as an Example
Journal of Kunming Medical University 2013;(12):30-32,36
Objectives To study the suicide attempts and suicide attitude status and the characteristics of Medical University undergraduates, provide specific recommendations for mental health education and counseling. Methods The investigation was conducted among 567 undergraduates and 130 graduate students in Kunming Medical University with Self-designed Suicide Attempts Investigation and Suicide Attitude Questionnaire (QSA), and the results of different groups were compared. Results 14.46%undergraduates had suicidal ideation, 4.23%undergraduates had suicide attempts, but there were no significant different between female and male. The suicide attitude in general was contradictory and neutral. Sex,academic qualification,grade, family location and economic status variables had influence on suicide attitude. Conclusions Although the medical university undergraduates disapproved of the suicidal behavior, but it still reflected the pursuit and respect for the humanistic concern and value of life to a certain extent.Suicidal attitude had significant different in demographic variables.
4.Sca-1~+ cells from mouse fetal liver can differentiate into neurons in vitro
Chinese Journal of Pathophysiology 1999;0(09):-
AIM: To study whether Sca-1 + cells from fetal liver can be induced to differentiate into neuronal cells in vitro. METHODS: Sca-1 + cells from 14 5-days-old murine fetal liver were isolated with a magnetic cell sorting kit, and were cultured in Dulbecco's modified Eagle's medium (DMEM)/F12 supplemented with 10% fetal bovine serum (FBS), and passaged at a ratio of 1∶3 when cells reached more than 80% confluence. The 5 passage cells were induced by 10 -3 mol/L ?-mercaptoethanol (?-ME) and 5 ?10 -7 mol/L all-trans-retinoic acid (RA) for 24 hours, and then incubated in serum-free medium for 5 hours to 5 days. The characteristics of treated cells were assayed by immunocytochemistry staining analysis at 5 hours, or 5 days.RESULTS: Cells treated with ?-ME and RA exhibited neuronal phenotype and expressed neuron-specific protein such as neuron-specific nuclear protein (NeuN), neuronfilament-M, and neuron-specific tubulin-1 (TuJ-1) but not tau, MAP-2, or the astrocyte-specific marker glial fibrillary acidic protein (GFAP).CONCLUSION: Sca-1 + cells from fetal liver, of which most are regarded as hematopoietic stem cells, could differentiate into early immature neuronal cells in vitro . These findings suggest that Sca-1 + cells from fetal liver may be an alternative source in cell therapy and gene therapy of neural dysfunction.
5.Fetal liver - derived Sca- 1~+ cells can differentiate into both neurons and astrocytes in vivo
Chinese Journal of Pathophysiology 1986;0(03):-
AIM: To determine whether Sca-1~+ cells from fetal liver can differentiate into neural cells. METHODS: The sex of 14.5-day-old murine fetuses was determined by PCR analysis of sry gene, and Sca-1~+ cells from male fetal liver were isolated with a magnetic cell sorting kit, 2?10~3 of which were then transplanted into lethally irradiated female mice. The donor cells and their characteristics in recipient brains were identified and detected by FISH and immunohistochemistry double-staining analysis at 60, 120, 180 days after transplantation. RESULTS: There existed many male cells in brains of female recipients, some of them express neuron-specific nuclear protein (NeuN), and some of them express the astrocyte-specific marker, i.e. glial fibrillary acidic protein (GFAP). CONCLUSION: Sca-1~+ cells from fetal liver, which contain hematopoietic stem cells, can differentiate into neuronal cells and astrocytes in the brains of adult mice.
6.Effects of ?-ME and RA on expression of GFAP in mesenchymal cells derived from mouse fetal liver
Chinese Journal of Pathophysiology 2000;0(11):-
AIM: To investigate the effects of ?-mercaptoethanol (?-ME) and all-trans rentinal acid (RA) on glial fibrillary acidic protein (GFAP) expression in mesenchymal cells derived from mouse fetal liver in vitro. METHODS: Cells suspension from 14.5-days-old mouse fetal liver were cultured in DMEM/HEPES/F12 supplemented with 20% FCS and mesenchymal cells were acquired after discarding nonadherent cells. The 5th passage cells were induced by ?-ME and RA. The characteristics of treated cells were assayed by immunocytochemistry staining at 5 hours and 5 days after induction. ?-actin as an internal control, GFAP gene expression of mesenchyal cells was detected with semi-quantitative RT-PCR. RESULTS: After being inducted by ?-ME and RA, 80% approximately of the cells exhibited typical neural morphology and about 85% expressed GFAP phenotype. Semi-quantitative RT-PCR showed that mRNA expression of GFAP increased in treated cells versus untreated cells (P

Objective:To investigate potency of mouse fetal liver mesenchymal cells differentiating into neural cells in vitro .Methods: Sterile cells from 14.5 day old mouse fetal liver were cultured in DMEM/HEPES/F12 supplemented with 20%FCS and adherent cells were acquired after discarding nonadherent cells. The 5th passage cells were induced by ? mercaptoethanol (? ME) and all trans retinoic acid (ATRA). The characteristics of treated cells were assayed by immunocytochemistry staining and semi quantitative RT PCR method on 5 h and 5 d after induction. Results: After induction by ? ME and ATRA, approximately 80% of the cells exhibited typical neuronal morphology;most cells expressed neuronal phenotype such as neuron specific nuclear protein(NeuN), neuron specific tubulin Ⅲ(TuJ 1), neurofilament M(NF M),and neuron specific enolase(NSE).However, microtubule associated protein tau(Tau 1)and microtubule associated protein 2 (MAP 2) as indicators of mature neuronal phenotype were undetectable. Semi quantitative RT PCR showed increased mRNA expression of brain factor 1(BF 1), brain 3(Brn 3), and neurofilament L(NF L) in treated cells versus untreated cells ( P
