BACKGROUND: Monosialotetrahexosylganglioside plays an important role in a variety of physiological processes, such as the nerve cel growth and development, differentiation, regeneration and intracel ular and extracel ular information transmission. OBJECTIVE: To investigate the effects of monosialotetrahexosylganglioside on the changes of gene expression and calcium ion concentration in the course of inducing the mesenchymal stem cells into neuron-like cells with Woodbury’s method. METHODS: The mesenchymal stem cells from Sprague Dawley rats were cultured after isolated and purified, After 5 passages in culture, the cel integrated into a dense monolayer, and treated with 50 mmol/L monosialotetrahexosylganglioside for 24 hours as the monosialotetrahexosylganglioside group; then the mesenchymal stem cells were induced into neuron-like cells with the methods of Woodbury after pre-cultured for 24 hours, and set the control group. The protein and mRNA expression levels of growth-associated protein 43, neuron-specific enolase, neurofilament and nestin were detected by immunocytochemistry and real-time PCR, respectively. The fluorescence intensity of intracel ular free calcium ion before and after inducing was detected by laser scan confocal microscope. RESULTS AND CONCLUSION: After induction, the expression levels of growth-associated protein 43, neuron-specific enolase, neurofilament and nestin of the mesenchymal stem cells in the monosialotetrahexosylganglioside group were higher than those in the control group (P < 0.05), demonstrating that monosialotetrahexosylganglioside could promote the differentiation of mesenchymal stem cells into neuron-like cells. The fluorescence intensity in mesenchymal stem cells was increased gradual y in two groups after the medium was replaced by the induction medium, attained its peak value at 100 seconds and then decreased gradual y, but the fluorescence intensity was stil higher than that before the induction at 20 minutes. The fluorescence intensity of intracel ular free Ca2+ was increased significantly in the monosialotetrahexosylganglioside group when compared with the control group (P < 0.05), suggesting that monosialotetrahexosylganglioside could increase the concentration of intracel ular free Ca2+, and intracel ular free Ca2+ may be useful in the course of induction. The changes of protein expression levels of growth-associated protein 43, neuron-specific enolase, neurofilament and nestin were not significant after induction, indicating that Woodbury classic induced programme could regulate the post-transcriptive protein level.

Objective To study the clinicopathological characteristics and prognosis of asymptomatie IgA nephropathy (IgAN) children with pmteinuria and/or microscope haematuria .Methods Clinical and pathological characteristics of 54 children with IgA nephropathy confirmed by renal biopsy were analyzed . These children with IgAN were divided into two groups according to their clinical characteristics at the first onset: asymptomatic IgAN group (AsIgAN) and symptomatic IgAN group (SIgAN) . Histologic changes were classified by Lee SM and Katafuchi semiquantitative scoring system . Results Eighteen children were in AslgAN group and 36 children were in SIgAN group . The degree of proteinuria in SIgAN group [(2 .3±2 .2) g/d] was higher than that in AslgAN group [(0 .4±0 .3) g/d] at the time of biopsy (P＜0 .05) . Although asymptomatic IgAN children were mainly of Lee's type Ⅰ ～Ⅱ, 2 children (11%) were of Lee's type Ⅳ～Ⅴ and 5 cases (27%) presented interstitial injury . Symptomatic IgAN children were mainly of Lee's type Ⅱ ～Ⅲ, there was no significant difference between two groups (P＞0 .05) . Urine micrealbumin was increased in 87% children presented with microscope haematuria . After an average of (26 .9±8 .8)months follow-up, only one case of Lee's Ⅴ progressed into renal failure and the others maintained normal renal function . Conclusions Although children with asymptomatic IgAN have minor clinical symptoms, severe renal pathological lesion and poor prognosis also occur . Urine screening helps to detect renal diseases and renal biopsy should be performed in the patients with increased urine microalbumin .

Objective To investigate the effects of Xuebijing injectio (Chinese herb preparation) on intestinal function and inflammatory responses in severe burn patients. Method Thirty-two patients with comparable severity in burn injury were randomly divided into Xuebijing injectio treatment group (n = 16) and control group (n = 16). Patients in both groups received routine burn therapy, while those in Xuebijing treatment group additionally received Xuebijing injectio 100mL in intravenous drip twice a day for 7 days. Before the treatment and on the 3rd and the 7th day after the treatment, blood concentrations of diamine oxidase (DAO), lipopolysaccharide (LPS) ,tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) were determined in both groups. Analysis was made by SPSS 12.0 software. Results The plasma levels of DAO, LPS, TNF-α and IL-6 were decreased in both groups after the treatment. However, the plasma levels of DAO, LPS, TNF-α and IL-6 in the Xuebijing treatment group were significantly lower than those in control group on the 3rd and 7th day after the treatment (P＜ 0.05).Conclusions Xuebijing injectio could protect intestinal function, decrease the plasma level of endotoxin and lessen zhe inflammatory responses in severe burn patients.

BACKGROUND: Bone marrow mesenchymal stem cell (MSC) is a kind of stem cell with potential of self-repair and multi-differentiation. It may differentiate into neuron, adipose cell and osteoblasts.OBJECTIVE: To observe the transforming efficacy of human bone marrow mesencymal stem cells (hMSCs) into neurons in vitro in different generations so as to provide reliable experimental data for the clinical application of MSCs.DESIGN: Single sample was designed.SETTING: Department of Neurology, Sino-Japan Friendship Hospital,Jilin UniversityPARTICIPANTS: Marrow tissue was collected from 9 cases of spinal fusion in Department of Orthopedics of First Hospital affiliated to Jilin University. Of 9 cases, all of them were in known of the experiment.METHODS: The experiment was performed in Sino-Japan Hospital affiliated to Jilin University from September 2002 to February 2003. The primary and generative culture of hMSCs was given. Experimental and the control groups were divided.-mercaptoethanol was taken as inducer. hMSCs of the 2rd, 4th, 6th and 8th generations were selected for induction in vitro for 6 h. Cytochemistry staining and immunohistochemistry staining were used to assay the expressions of neuronal and astrocytic marked proteins.MAIN OUTCOME MEASURES: ① Growth curve analysis on genera tive culture of hMSCs. ② Nissel staining. ③ Immunohistochemical staining.RESULTS: ① Common characters of generative culture: The latent phase of generative culture was 12-24 hours, exponential phase was 7-10 days and 11-13 days later, cell culture entered the platform phase. ② After induction of the 2nd, 4th and 6th generated hMSCs, deep blue granular Nissl body presented in cytoplasm. In 6 hours on the 8th induction, there was no obvious deep blue Nissl structure presented in cytoplasm.③ Except GFAP, NSE and NF-M were expressed in hMSCs of different generations after induction for 6 hours. There was no significant difference in positive rates of the 2nd, 4th and 6th generations (P ＞ 0.05), but the significant difference presented in comparison between the 8th generation and the 2nd, 4thand 6th generations (P ＜ 0.05). CONCLUSION:-mercaptoethanol can induce hMSCs differentiating into neuronal cells in vitro. The positive rates of the 2nd, 4th and 6th generationsare higher remarkably than the 8th generation.
