AIM: To study the protocol and condition that induce bone marrow stromal cells (MSCs) to differentiate into neuron in vitro by baicalin, a kind of flavonoid isolated from an important medicinal plant Scutellariae Radix . METHODS: MSCs from adult rats were induced by baicalin in serum-free medium for 6 h, and postinduced for 6 d. The morphological changes of MSCs were evaluated by light microscope. The positive percentages of neuron-specific enolase (NSE), 200-kilodalton neurofilament (NF), glial fibrillary acidic protein (GFAP) and vimentin expression were measured by immunocytochemistry with ABC staining. Hoechst 33258 staining was used to measure the cell viability by fluorescence microscope. RESULTS: After induction for 6 d, MSCs displayed neuronal morphologies, such as pyramidal cell bodies and processes formed extensive networks. The positive percentages of NSE, NF, GFAP and vimentin protein expression were 70.5%?11.6%, 68.3%?13.4% ,

BACKGROUND:Hyperbaric oxygen(HBO)treatment promotes the proliferation and differentiation of endogenous neural stem cells in neonatal rats following hypoxic/ischemic brain damage(HIBD).The Wnt signaling pathway is associated with neurogenesis.However,there are few data recording the role of HBO in the differentiation of neural stem cells in vitro.OBJECTIVE:To observe the effect of HBO on differentiation and Wnt3 expression of bone marrow mesenchymal stem cells(BMSCs).METHODS:BMSCs were isoiated and cultured.The rat BMSCs of passages 3-5 were cultured in DMEM/F12(1:1)medium with basic fibroblast growth factor,epidermal growth factor and B27 for 24 hours.The induced BMSCs were randomly divided into two groups:control group(no treatment)and HBO group(HBO,0.10 MPa,60 minutes stabilizing pressure with at least 90% oxygen).The neuron specific encloase(NSE),glial fibrillary acidic protein(GFAP)and 04 marked oligodendrocyte immunocytochemistry were detected by immunofluorescent staining,and Wnt3 protein expression was detected by Western-blot.RESULTS AND CONCLUSION:BMSCs cultured in classic medium of neural stem cells could significantly induce the expression of nestin.The expression of NSE and 04 of HBO group was greater than control group(P＜0.01),but GFAP expression displayed no significant difference between the groups(P＞0.05).Western blot showed HBO could enhance the Writ3 expression (P＜0.05).Results show that HBO can induce BMSCs to differentiate into neural cells and oligodendrocyte,which is correlated with the activation of the Wnt3 protein.

BACKGROUND: Perinatal hypoxic-ischemic encephalopathy(HIE) is the primary cause of neonatal brain injury, which retards the mental development in affected infants.OBJECTIVE: To investigate the influence of early intervention on mental and psychological development in infants with HIE, study the time-effect relation of the early intervention, and to find an optimal time for intervention.DESIGN: A time series of following-up and a non-randomized concurrent controlled investigation.SETTING: Xiangya Hospital and Xiangya School of Medicine Affiliated to Central South University.PARTICIPANTS: From February 1999 to May 2001, in the Pediatric Department of Xiangya Hospital Affiliated to the Central South University, the inpatient and outpatient infants with HIE were selected. There were 32 inpatients in the intervention group, 10 with moderate HIE and 22 with severe HIE. There were 36 outpatients in the control group, 10 with moderate HIE and 26 with severe HIE. Comparison was performed between these two groups.METHODS: BRS and the Infant and Child Mental Development Scales,made by The Institute of Psychology of The Chinese Academy of Science and The China National Children' s Center(CNCC), were adopted in the assessment between the two groups.MAIN OUTCOME MEASURES: Mental Development Index(MDI) and Psychomotor Development Index(PDI) scores of the two groups were compared.were significantly higher in the intervention group(90.50 ± 11.12/90. 34±12.49,94.06±14.96/92.03±13.07,90.78±7.46/91.38 ± 13.87)than those in the control group(62.28±7.44/62.67±6.06, 59.11following-up results showed that one patient in the intervention group had a MDI score at the critical threshold value, and two patients had PDI scores at the critical threshold value. For all the other patients in this group, the MDI/PDI scores of them were above the moderate range. In contrast, all the 36 infants in control group had developed mental deficiencies at that time.CONCLUSION: A quantifiable effect of the intervention can be observed in patients at 3 months of life. This indicates that an early intervention is essential for improving the mental development in infants with HIE.

Objective To investigate the distribution of different Human papilloma virus(HPV) subtype infection of women cervixes in parts of Guizhou Province and the high risk factors of HPV infection,in order to offer some evidences for the use of vaccine of cervix eaneers in the region, and offer a group of reliable data for the screen-ing statistics of cervix eaneer in the world. Methods A total of 2339 women having sexual life were checked for 21 HPV genotypes by DNA flow-through hybridization technique and liquid-hased pap test(LPT) in their exfoliated cer-vical cells. Cervix tissues were taken in some HPV positive women and (or) LPT positive women among them for bi-opsy by the vaginoscope. The high risk factors of HPV infection and the distribution feature of HPV subtype infection in the different cervix diseases were anlayzed. Results The total positive rate of HPV infection was 30.31% (709/ 2339 ) in the 2339 women. There were 20 HPV subtypes to be detected. HPV subtype infection from high to low were HPVI6,52,18,58 and 11. The rates of HPV subtype infection were 9.87% (231/2339) ,5.64% ( 132/2339), 4.95% (116/2339 ) ,4.19% (98/2339)and 2.99 % (70/2339). The peak age of HPV infection ranged from 31 to 35 years old. The earlier the first sexual life,the higher HPV infeetion (tendeney X2 test,P <0.05). 366 CIN pa-tients and 181 patients of invasive cervix carcinoma( ICC)were diagnosed through pathology examination. The rate of HPV infection were 34.26% (74/216)in CIN Ⅰ ,77.78% (56/72)in CIN Ⅱ ,82.05% (64/78)in CIN Ⅲ. Among the 181 ICC,the rate of HPV infection was 84.52% (131/155)in squamous carcinoma of the cervix (SCC) and 38.46% (10/26) in adenocareinoma of uterine cervix (AUC). The infeetion rate of HPV16 was 61.83% ( 81/131 ) in the SCC of HPV positive. The infection rate of HPV18 was 60% (6/10)of the AUC of HPV positive. HPV16 was related closely with SCC ( X2 = 11. 948 ,P < 0.001 , ORSCC/AUC = 5. 946). There was no significant difference be-tween HPV 18 in SCC and AUC( P > 0.05). Conclusions The major HPV subtypes are 16,52,18,58 in Guizhou province. There is a close correlation between HPV infection and cervix diseases. HPV infection often occurs in young and middle-aged women. The first sexual life is a high factor of HPV infection. High risk HPV infecting would cause cervix cancer. CIN and cervix cancers are caused by high risk HPV infection. HPV16 is related closely with SCC. There is no significant difference between HPV18 in SCC and AUC. HPV16/18 vaccine could be considered to re-duce the incidence of cervical carcinoma in Guizhou province.
