Objectives To detect the expression of STAT3 in children with FCD (focal cortical dysplasias) type IIIa. Methods The expression of STAT3 and P-STAT3 (ser727) were determined in temporal lobe specimens from 26 children with FCD type IIIa and from 5 normal control by immunohistochemistry, immunolfuorescence and Western blot. Results The expression of P-STAT3 (ser727) was obviously higher in FCD type IIIa than in control group. P-STAT3 (ser727) was located mainly in the nucleus of astrocytes. Conclusions Activated STAT3 might contribute to the patholgenesis of FCD type IIIa by mediating proliferation of astrocytes.

BACKGROUND:Bone marrow mesenchymal stem cells (BMSCs) can differentiate into renal paranchymal cells including renal intercapillary cells.BMSCs can repair kidney structure and function after damage.OBJECTIVE:To investigate renal histology and function changes following BMSC transplantation in a rat model of radiation-inducad damage.DESIGN,TIME AND SETTING:The cytological in vitro study was performed at the Laboratory of the Department of Hematology,Zhujiang Hospital from January to October 2009.MATERIALS:A total of 35 clean male Sprague Dawley rats were selected.Of them,20 were used to prepare BMSCs.The remaining was randomly assigned to a normal control,model and cell transplantation groups,with 5 in each group.METHODS:Rat BMSCs were incubated by the whole bone marrow method.When 90% cells were confluent,BMSCs were digested in trypsin for subculture.In the model and cell transplantation groups,rats were used to establish radiation-induced models,and then underwent X-ray general irradiation,at a dose of 500 cGy/min,100 cm from the target,6 Gy each,once per week,for consecutively 3 weeks.24 hours following irradiation,BMSCs of 3 passage were collected at logarithmic phase.In the cell transplantation group,1 mL cell suspension was infused into the rat caudal vein,containing 3×10~6 cells,totally three times.In the normal control and model groups,rat caudal vein received an equal volume of saline.MAIN OUTCOME MEASURES:The following parameters were measured:results of hematoxylin-eosin staining;serum and kidney malondialdehyde (MDA) content and superoxide dismutase (SOD) activity;serum creatinine and urea nitrogen levels.RESULTS:Kidney histopathology demonstrated thin renal cortex,increased number of mesenchyme,uneven renal corpuscle,and disordered structure of renal glomerulus,narrow renal glomerular vessel,partial disappeared capsular space,and degeneration and sclerosis of some glomerulus in the model group.In the cell transplantation group,renal cortex became thick,with clear structure;interstitial hyperemia and edema was significantly relieved;many complete renal corpuscles were observed;partial renal glomerulus presented degeneration and sclerosis;significant capsular space could be seen.Oxygen free radical examination results showed that compared with the model group,SOD activity was significantly higher (P < 0.05),MDA levels were significantly lower (P <0.05) in the cell transplantation group.Renal function examination results demonstrated that compared with the model group,serum creatinine and urea nitrogen levels were significantly reduced in the cell transplantation group (P < 0.05).CONCLUSION:BMSC transplantation can effectively treat renal radiation injury and improve renal function.

Objective To investigate the effects of brain-derived neurotrophic factor (BDNF) pretreatment on neuron apoptosis and the expression of Bcl-2 and Bax protein following global cerebral ischemia-reperfusion (I/R) injury in gerbils. Method Forty-eight mongolian gerbils were randomly divided into six groups in equal number (n = 8): normal control group (group C), ischemia-reperfusion group (group I/R) and four BDNF pretreatment groups according to various lengths of time from BDNF pretreatment to ischemia-reperfusion. The BDNF pretreat-ment was carried out in gerbils with lateral ventricular injection of BDNF 0.5μg 6 h, 12 h,24 h and 48 hours be-fore cerebral ischemia, and those gerbils assigned into PR6, PR12, PR24 and PR48 groups. The global cerebral is-chemia-reperfusion was induced by occlusion of bilateral common carotid arteries for 20 minutes and then the arter-ies were released for 24 hours reperfusion. The confirmation of global cerebra ischemia was evidenced by the ap-pearance of mydriasis and disappearance of light reflex and righting reflex. Twenty-four hours later, all gerbils including those of control group were sacrificed and a piece of tissue was taken from frontal cortex just behind the optic chiasma 1~4 millimeter for making paraffin sections. Neuron apoptosis was identified by using TUNEL and immunohischemistry was used to detect the expression of Bcl-2 and Bax protein in cerebral cortex. The data were analyzed by using analysis of variance. Results There were no apoptotic cells, and expression of Bcl-2 and Bax protein positive cells found in group C. Neuron apoptosis in brain cortex was detected in I/R group and BDNF pre-treatment groups. The indexes of neuron apoptosis in BDNF pretreatment groups were markedly lower than those in group I/R (P < 0.01). Compared with group I/R, the index of expression of Bcl-2 protein positive cells was in-creased significantly in BDNF pretreatment groups (P = 0.005), while the index of expression of Bax protein posi-tive cells were decreased significantly (P < 0.01 in all groups). Among 4 BDNF pretreatment group, the lowest apoptosis index and lowest of expression of Bax protein positive cells were found in PR6 and PR12 BDNF pretreat-ment groups (P = 0.0056 and 0.001, respectively). Conclusions Different time windows of BDNF pretreatment can decrease the neuron apoptosis in different degree, and protect brain against cerebral ischemia-reperfusion injury significantly. Among BDNF pretreatment time windows, pretreatment of 6 hours and 12 hours are the better ones.The mechanism of protection of BDNF pretreatment may be attributed to inducing Bcl-2 protein expressions and in-hibiting Bax protein expressions, and thereby inhibiting neuron apoptosis.
