BACKGROUND: The marginal division, a new sub-region in rat brain striatum discovered in recent decades, has been found to closely relate to learning and memory function of the brain. The immediate-early genes such as c-fos and c-jun participate in the signal transduction of learning and memory in the marginal division. But what other intermediate events are initiated in the marginal division in the process of learning and memory?Cyclic adenosine monophosphate (cAMP) response element-binding protein (CREBP) is an molecule essential for the formation of long-term memory,and investigation of the expression and distribution of phosphorylated CREBP in the striatum may help understand the signal transduction mechanism in the striatum during learning and memory at the molecular level.OBJECTIVE: To investigate the expression of phosphorylated CREBP in rat brain stratum during learning and memory process.DESIGN: Completely randomized controlled study.SETTING: Institute of Neurosciences, Zhujiang Hospital of the First Military Medical University of Chinese PLA.MATERIALS: This experiment was conducted in the Institute of Neurosciences, Zhujiang Hospital of the First Military Medical University of Chinese PLA between April and August 2003. Totally 48 normal male adult SD rats were provided from the Experimental Animal Center of First Military Medical University, and after two Y-maze tests, 40 rats were selected for this study (MG-2 type, Sanshengxing electricity company).METHODS: The 40 SD rats were randomized into 4 equal groups. The rats in the first group were subjected to training to acquire dark avoidance reflex in a Y maze, those in the second group underwent sham training with only light stimulation in the Y maze without electricity on the floor.The rats in the third group were trained in the Y maze with electricity on the floor but not light stimulations, with the rest 10 rats serving as the control group subjected to sham training in the Y maze without either electric or light stimulations. After the training in the Y maze, the rats were sacrificed immunohistochemical detection of phosphorylated CREBP expression in the brain striatum.MAIN OUTCOME MEASURES: Expression of phosphorylated CREBPin rat brain striatum.RESULTS: All the 40 rats enrolled in this study were examined for phosphorylated CREBP expression. Positive expression of phosphorylated CREBP was observed in the medial marginal division of the brain striatum after the rats were trained in the Y maze with electric stimulation, but no obvious expression was seen in rats in the sham training or control groups.Massive expression of phosphorylated CREBP could be observed, typically,in the hippocampus, front prefrontal lobe cortex and cingulate gyrus of the rat brain.CONCLUSION: The transcriptional factor phosphorylated CREBP in the marginal division of the striatum participates in the signal transduction for learning and memory in rats receiving Y maze training to acquire dark avoidance reflex.

Objective To compare the effects of 6MV and 10MV-X-ray intensity modulated radiotherapy (IMRT) on non-small-cell lung cancer (NSCLC) . Methods We randomly selected 20 patients with NSCLC, 6MV and 10MV X-ray were used respectively for each NSCLC patient with IMRT plan design, the ADAC Pinnacle 8.0f treatment planning system was applied to provide the convolution/iteration algorithm, for the same target IMRT plan design with two kinds of energy. By comparing the dose volume histogram (DVH),PTV parameter (Dmean, Dmin and Dmax), conformal index (CI) and homogeneity index (HI),we analyzed the metrology parameters . Results 6MV and 10MV radiation therapy plan DVH, PTV parameters,CI,HI and isodose line was similar,no statistically significant differences. But target dose homogeneity and the degree of target coverage in high dose of 6MV plan was better than that in 10MV plan. Endanger organs (OAR) such as normal lung tissue, heart, esophagus and spinal cord had basically same dose amount. Conclusion 6MV X-ray plan may be the better choice of radiotherapy on NSCLC.

Objective To explore the changes of plasma orexin-A level before and after operation in obstructive sleep apnea-hypopnea syndrome(OSAHS) children and its effect on their behavior performance.Methods 120 cases OSAHS children performed tonsillectomy and / or adenoidectomy and 30 cases normal children as control group.According to the AHI index,the OSAHS group was divided into mild group (5 times/h ≤ AHI ＜ 20times/h,n=13),moderate group (20/h ≤ AHI ＜40/h,n=76),and severe group (AHI ≥ 40 times / h,n=31).And at the same time,according to the sensory integration ratings,OSAHS group was divided into normal group(n =30),mildly abnormal group (n =47),moderately abnormal group (n =28),severely abnormal group (n =15).Before operation and 6 months after operation,plasma orexin-A levels and children's sensory integration were measured.Results Plasma orexin-A level of the OSAHS group ((0.41 ± 0.06) μg/ml) was significantly higher compared with the control group((0.31±0.04) μg/ml) (P＜0.01).In orexin-A level of different AHI groups before and after operation(mild group:(0.33±0.02) μg/ml vs (0.28± 0.03) μg/ml,moderate group:(0.39±0.04) μg/ml vs (0.29±0.03) μg/ml,severe group:(0.49±0.04) μg/ml vs (0.32± 0.02) μg/ml),there had significant differences (P＜0.01).In OSAHS children,AHI index had positive correlation with preoperative plasma orexin-A level (r=0.803,P＜0.01).There was a significant negative correlation between sensory integration scores and plasma orexinA level(r=-0.812,P＜0.01).Conclusions Plasma orexin-A level of OSAHS children is closely related to the severity of OSAHS and the changes of their behavioral ability.And it may become a diagnostic plasma marker of OSAHS children.

There was no significant difference in body weight of mice before and after medication. CONCLUSIONS:ATMP has significant analgesic and anti-fatigue effects on mice and anti-inflammatory effect on rats.

Objective To observe the tendency of the plasma concentration of plasminogen activator inhibitor type-1 (PAI-1) and thrombin activatable fibrinolysis inhibitor (TAFI) before and after thrombolytic treatment of acute ST elevation myocardial infarction (STEMI) and to explore their recanalization predictive value of PAI-1 and TAFI for acute myocardial infarction patients with thrombolytic treatment.Methods Sixty patients,who received thromobolytic treatment from January 2007 to March 2009,were prospectively recruited.The blood sample were collected within 2 hours of thromobolytic treatment ( 0,0.5 h,1 h,1.5 h and 2 h).The plasma concentration of TAFI and PAI-1 were test by ELISA.16 healthy people were recruited as control group.Results The plasma levels of PAI-1 in STEMI patients before thrombolytic treatment were higher than those of Control group ( P ＜0.01 ),however the same significant change of TAFI level was not seen.The levels of TAFI were no significant difference before and after thrombolytic therapy during whole observation periods.However,the level of PAI-1 increased at 1.5 h and 2 h after thrombolytic therapy (P ＜ 0.01 ).The plasma PAI-1 levels of no - revascularigation group at 2 h after thrombolytic therapy were significant higher than that in revascularization group ( P ＜ 0.05 ).The levels of TAFI were not significantly different between two groups (P ＞ 0.05).Conclusions The decrease of plasma PAI-1 from high level within 2 hours after thrombolysis treament may be exploring the predictive value for revascularization.The tendency of TAFI can' t forecast the result of revascularization.

Intraocular pressure detection has a great significance for understanding the status of eye health, prevention and treatment of diseases such as glaucoma. Traditional intraocular pressure detection needs to be held in the hospital. It is not only time-consuming to doctors and patients, but also difficult to achieve 24 hour-continuous detection. Microminiaturization of the intraocular pressure sensor and wearing it as a contact lens, which is convenient, comfortable and noninvasive, can solve this problem because the soft contact lens with an embedded micro fabricated strain gauge allows the measurement of changes in corneal curvature to correlate to variations of intraocular pressure. We fabricated a strain gauge using micro-electron mechanical systems, and integrated with the contact lens made of polydimethylsiloxane (PDMS) using injection molding. The experimental results showed that the sensitivity was 100. 7 µV/µm. When attached to the corneal surface, the average sensitivity of sensor response of intraocular pressure can be 125.8 µV/mm Hg under the ideal condition.

To assess a novel cell manipulation technique of tissue engineering with respect to its ability to augment superparamagnetic iron oxide particles (SPIO) labeled mesenchymal stem cells (MSCs) density at a localized cartilage defect site in an in vitro phantom by applying magnetic force. Meanwhile, non-invasive imaging techniques were use to track SPIO-labeled MSCs by magnetic resonance imaging (MRI). Human bone marrow MSCs were cultured and labeled with SPIO. Fresh degenerated human osteochondral fragments were obtained during total knee arthroplasty and a cartilage defect was created at the center. Then, the osteochondral fragments were attached to the sidewalls of culture flasks filled with phosphate-buffered saline (PBS) to mimic the human joint cavity. The SPIO-labeled MSCs were injected into the culture flasks in the presence of a 0.57 Tesla (T) magnetic force. Before and 90 min after cell targeting, the specimens underwent T2-weighted turbo spin-echo (SET2WI) sequence of 3.0 T MRI. MRI results were compared with histological findings. Macroscopic observation showed that SPIO-labeled MSCs were steered to the target region of cartilage defect. MRI revealed significant changes in signal intensity (P<0.01). HE staining exibited that a great number of MSCs formed a three-dimensional (3D) cell "sheet" structure at the chondral defect site. It was concluded that 0.57 T magnetic force permits spatial delivery of magnetically labeled MSCs to the target region in vitro. High-field MRI can serve as an very sensitive non-invasive technique for the visualization of SPIO-labeled MSCs.
