BACKGROUND:Compared with mesenchymal stem cells from bone marrow and fat, human umbilical cord-derived mesenchymal stem cells, as one of the most potential cellsources to repair the central nervous system, are easy-based, more primitive, and not limited by ethical and legal.
OBJECTIVE:To explore differentiation of human umbilical cord-derived mesenchymal stem cells into neural stem cells induced by the recombinant human basic fibroblast growth factor and recombinant human epidermal growth factor.
METHODS:The human umbilical cord-derived mesenchymal stem cells were induced by basic fibroblast growth factor and epidermal growth factor in vitro. The cellmorphology was observed by invert microscope. The differentiation status was detected by immunofluorescence. The Nestin expression in mRNA level before and after induction was detected by real-time PCR.
RESULTS AND CONCLUSION:The neural stem cellbal s were observed after induction. And the Nestin was detected by immunofluorescence and real-time PCR. Nestin could further differentiate to the neuronal markproteins neuron-specific enolase, microtubule-associated protein 2 protein and glial fibril ary acidic protein. Results from this study show that basic fibroblast growth factor and epidermal growth factor can induce human umbilical cord-derived mesenchymal stem cells to differentiate to neural stem cells, neurons and glial cells.

Objective To investigate the effects of normobaric hyperoxia intervention on learning and memory abilities of valproic acid(VPA) autism model rats and the morphology of pyramidal cells in hippocampus CA1 area.Methods Animal model groups of autism were obtained in male offspring of the Wistar rats that received intraperitoneal injection of 600 mg/kg VPA at the 12.5 day after pregnancy.According to the eye opening time,behavior,weaning weight and the learning and memory abilities which were evaluated by the Y electricity maze test at the 28th day after birth,40 male VPA autism model rats were randomly selected 20 only and divided into normobaric hyperoxia model group (group A,n =10),atmospheric air model group (group B,n =10).Normal control groups were obtained in male offspring of Wistar rats that received intraperitoneal injection of equivalent physiological saline at the same period pregnancy.(group C,n =10).Rats in group A were treated with oxygen for 1 h per day and lasted 1 week;group B and C were treated with normal air.The learning and memory abilities of three groups were assessed at the 35th day after birth.The immunohistochemistry methods and image analysis were used to observe the pyramidal cells of autism model rats in hippocampal CA1 region.The effect of normobaric hyperoxia therapy on pyramidal cell of autism model rats in hippocampal CA1 region were evaluated by HE staining technique.Results The trying times of group A after treatment were less than those before treatment (31.15 ± 0.99 vs 31.54 ± 0.97,t =2.739,P =0.018).The memory times were more than those before treatment (3.00± 0.58 vs 2.69 ± 0.48,t =-2.309,P =0.040).The trying times of group A after treatment were less than those in group B after treatment (P =0.016).The memory times of group A were not different from that in group B after treatment(P=0.810).The morphology of pyramidal cells in hippocampal CA1 region showed that the pyramidal cells of the autism model rats had apoptosised.The number of apoptotic cells reduced and the number of normal form cells increased after the normobaric hyperoxia intervention compared with the autism model rats.Conclusion Normobaric hyperoxia intervention can improve the learning and memory abilities of the autism model rats.The apoptosis of the pyramidal neurons in hippocampal CA1 might be reduced after the normobaric hyperoxia intervention.

Objective To investigate the influences of psychological rehabilitation nursing on immune function in post stroke depression patients.Methods A total of 80 elderly patients with post stroke depression were recruited from the inpatients in geriatric neurology department at Tianjin Medical University General Hospital.All patients were divided into two groups:the control group received only conventional and auxiliary exercise therapy for 3 months; rehabilitation group received psychological rehabilitation nursing added to the above therapy for 3 months.Barthel indexes,Hamilton Depression Scale (HAMD) scores and immune function were detected at recruit and three months after treatment.Results There were no statistically significant differences in clinical data between the rehabilitation group and control group (all P＞0.05).There were no statistically significant differences in Barthel indexes,Hamilton Depression Scale (HAMD) scores and immune function between rehabilitation group and control group before treatment (all P＞ 0.05).Compared with control group,the rehabilitation group showed that the Barthel Indexes were increased (P=0.000),Hamilton Depression Sale (HAMD) scores were decreased (P=0.000),the levels of T lymphocyte subpopulation (P＜ 0.05) and immunoglobulin (P＜ 0.01) were increased after three months treatment.Conclusions The combination treatment of psychological rehabilitation nursing,auxiliary exercise and drug are helpful to recover immune function and improve the quality of life in patients with post stroke depression.

Objective To study the sonographic features of mammary sclerosing adenosis (SA) and evaluate the diagnositic value of ultrasound. Methods Thirty-ifve patients with pathologically conifrmed SA in Ruijin Hospital from May 2009 to August 2013 were retrospectively analyzed. The Breast Imaging Reporting and Data System (BI-RADS) lexicon was introduced to describe the lesions. The diagnostic sensitivity was analyzed. Results The main sonographic ifndings of SA could be characterized into three types:(1) malignancy-looking nodule type (typeⅠ) (34%, 12/35). (2) benignity-looking nodule type (typeⅡ) (43%, 5/35). (3) architectural disorder type (typeⅢ) (23%, 8/35). Lack of blood supply has the greatest value in differential diagnosis among all sonographic features. The diagnositic sensitivity in typeⅠ, typeⅡ, typeⅢwere 0 (0/12), 93%(14/15), and 75%(6/8) respectively. The general sensitivity was only 57%(20/35). Conclusions There are no typical sonographic features in mammary sclerosing adenosis. Ultrasound doctors should improve their knowledge about this disease.

Objective To explore the preventive effect of early umbilical cord mesenchymal stem cells (UC-MSCs) transplantation on MRL/lpr mice and the underly mechanisms.Methods Fourteen 10-week-old MRL/lpr mice were labeled and numbered.They were randomly divided into 2 groups by using random number table and injected with 1 ×106 UC-MSCs or PBS via tail vein respectively.Proteinuria was measured with Bradford method every 4 weeks.All mice were sacrificed at the age of 28 weeks, with the level of serum antidsDNA antibody and IL-17 detected by enzyme linked immunosorbent assay (ELISA).Splenic Th17 cells, as well as regulatory T cells (Treg) were examined by flow cytometry.Data were analyzed with t test and Pearson's correlation test.Results The onset of proteinuria was delayed for 4 weeks in UC-MSC-treated group compared with that in the control group.At the age of 28 weeks, the 24 hour proteinuria [(1.78±0.17) mg vs (4.77±0.98)mg, t=2.99, P＜0.05] and the spleen weight [(0.149±0.009) g vs (0.273±0.052) g, t=2.33, P＜0.05] in UC-MSCtreated group were significantly lower than those in the control group.There was also a trend of the decline of serum anti-dsDNA antibody and IL-17 level after UC-MSCs transplantation.Compared with those in the control group, both the percentage and the absolute number of Th17 cells were significantly decreased in UC-MSC-treated group [(0.90±0.19)％ vs (2.81±0.50)％, t=3.54, P＜0.01 and (3.7±0.8)×105 vs (19.3±3.7)×105, t=4.12,P＜0.01].Meanwhile, the percentage of Treg elevated after UC-MSCs treatment.The ratio of Th17/Treg was significantly lower in UC-MSC-treated group than that in the control group (0.11±0.03 vs 0.50±0.09, t=4.23,P＜0.01).Both the ratio of Th17/Treg (r=0.73, P＜0.01;r=0.59, P＜0.05) and serum IL-17 level (r=0.78, P＜0.01;r=0.56, P＜0.05) was positively correlated with the level of 24 hour proteinuria and anti-dsDNA antibody respectively in MRL/lpr mice.Conclusion Early UC-MSCs transplantation helps to delay disease onset and ameliorate disease progression in MRL/lpr mice, which may act through the modulation of Th17/Treg balance.

Objective Whether the bone marrow cells (BMC) derived from systemic lupus erythematosus (SLE) could transmit autoimmune disease was studied for the purpose of clarifying the role of BMC in SLE pathogenesis.The effects of bone marrow mesenchymal stem cells (MSC) from SLE and control mice on the SLE BMC-induced symptoms were compared to elucidate the role of MSC in SLE.Methods Six-week-old B6.MRL-Fas mice were randomly divided into 3 groups.One group was transplanted with BMC from the 30-week-old B6.MRL-Faslg mice.One group was co-transplanted with BMC from the 30-week-old B6.MRL-Fasr mice and bone marrow MSC from the age-matched B6.MRL-Faslpr mice.One group was co-transplanted with BMC from the 30-week-old B6.MRL-Faslg mice and bone marrow MSC from the age-matched C57BL/6 mice.Before transplantation,the recipient mice received irradiation by an X-ray source.The levels of serum antinuclear antibody (ANA) and proteinuria were measured with enzyme linked immunosorbent assay (ELISA) and Bradford method every 4 weeks,respectively.The survival rate was recorded.All mice were sacrificed 18 weeks later.Splenic plasma cells,Th1,Th2 and Th17 cells were measured by flow cytometry.Statistical analyses were performed using the independent t test and ANOVA.Results Eight weeks after transplantation,ANA was positive in all the recipient mice.However,there was no significant difference between the three groups (P＞0.05).No proteinuria was observed in all the recipient mice.The mice received BMC from the 30-week-old B6.MRL-Fasr mice and bone marrow MSC from the age-matched B6.MRL-Fasr mice showed an elevated trend of the percentages of splenic plasma cells,Th1,Th2 and Th17 cells compared with the other two groups,plasma cells [(1.05±0.16)％,(0.58±0.11)％,t=2.53,P＞0.05;(1.05±0.16)％,(0.71±0.18)％,t=1.45,P＞0.05],Th1 cells [(6.6±2.2)％,(5.7±1.0)％,t=0.38,P＞0.05;(6.6±2.2)％,(4.0±1.7)％,t=0.96,P＞0.05],Th2 cells [(3.3±0.4)％,(2.1±0.6)％,t=1.76,P＞0.05;(3.3±0.4)％,(2.2±0.6)％,t=1.51,P＞0.05],Th17 cells [(2.30±0.71)％,(1.31±0.31)％,t=1.27,P＞0.05;(2.30±0.71)％,(1.12±0.27)％,t=1.67,P＞0.05].However,there was no significant difference between the groups.The survival rate of the three groups was 43％,43％ and 80％ respectively.And the survival rate of the mice received BMC from the 30-week-old B6.MRL-Fasr mice and bone marrow MSC from the age-matched C57BL/6 mice was significantly higher than those of the other groups.Conclusion Our results indicate that BMC from SLE can transmit autoimmune disease.The bone marrow MSC can not prevent lupus-like presentations induced by BMC from SLE.Transplantation of bone marrow MSC from C57BL/6 mice can significantly elevate the survival rate.
