Attention deficit hyperactivity disorder(ADHD) and developmental coordination disorder(DCD) are both childhood disorders identified in the DSM-Ⅳ.Studies investigating ADHD have found that around half of ADHD cases also have motor problems severe enough to be diagnosed as DCD.Further,children initially diagnosed as DCD have also been found to meet moderate to severe diagnosis for ADHD.Both disorders have been linked to a lot of psychosocial problems.Furthermore,when ADHD and DCD are co-morbid,the outcome tends to be more severe than when either disorder occurs alone.In the past decade,many studies identified shown that ADHD children experienced difficulties with both fine motor movements and gross motor movements.Notably,most of these foregoing studies found balance functions of ADHD were impaired.In order to maintain balance under a verity of environmental conditions,sensory information from somatosensory,visual,and vestibular origins must be integrated by the central nervous system.But there are rich evidences suggesting that children with ADHD can not organize the motor information effectively.The maintenance and control of posture and balance,whether in static or dynamic conditions,are essential requirements for daily activity.The balance function has been closely associated not only with both gross motor movements,such as sitting,standing,walking and fine motor movements,but also with human behaviors.There are increasing evidences suggesting that balance deficit correlates with symptoms of ADHD.Therefore,motor coordination difficulties co-occurring with ADHD should be given emphasis in clinical practice;the training of balance may be one of the possible methods to improve the motor coordination function in ADHD children.

Objective To observe the effects of butylphthalide on the expression of autophagy-related protein and mRNA in l-meth-yl-4-phenyl-pyridiniumion (MPP+)-induced SH-SY5Y cells, and to explore the protective effect and possible mechanism of butylphthalide to the cell model of Parkinson's disease. Methods The SH-SY5Y cells were divided into control group (A), MPP+group (B), rapamycin pre-treated+MPP+group (C) and Butylphthalide pretreated+MPP+group (D). The relative viability of SH-SY5Y cells induced by MPP+was measured with MTT assay, the morphology of SH-SY5Y cells was observed. The expression of microtubule associated protein 1 light chain 3 (LC3)-II/I and Beclin 1 protein was detected by Western blotting. And the expression of LC3-II/I and Beclin 1 mRNA were assayed by re-al-time quantitative reverse transcription-PCR (RT-PCR). Results The viability rates of cells were significantly lower in group B than in group A (t=20.270, P<0.001), and were significantly higher in groups C and D than in group B (t>8.770, P<0.001), however, there was no significantly difference between groups C and D (t=2.270, P=0.064). The expression of LC3-II/I and Beclin 1 was higher in group B than in group A (t>6.647, P<0.01), and was higher in groups C and D than in group B (t>3.630, P<0.01), however, there was no significantly differ-ence between groups C and D (t<2.238, P≥0.05). Conclusion Butylphthalide could prevent the injury of SH-SY5Y cells induced by MPP+, which may affect Parkinson's disease by inducing autophagy.

Proteome research has become a new hot spot in the post-genome era. High-resolution two-dimensional gel electrophoresis (2-DE), which provides the most comprehensive analysis system of the whole proteome, was highly improved in recent years. With the development of computer techniques, the powerful and user-friendly image analysis systems appeared to help high-throughput, large-scale proteomic studies. Using new generation two-dimensional image analysis software, ImageMaster 2D Elite, the 2D gels of proteins extracted from cultured Schwann’s cells were processed. The analysis procedure, including image acquirement, spot detection, match, background subtraction, pI/Mr calibration, analysis results report and database query, were reported and discussed.

AIM:To analyze circulating miR-141 in the serum as a non-invasive biomarker in the patients with prostate cancer ( PCa) and benign prostate hyperplasia ( BPH) , and healthy individuals.METHODS: A total of 75 pa-tients with PCa, 52 with BPH and 40 healthy individuals were enrolled into this study.Total RNA was isolated from the se-rum samples and the circulating levels of miR-141 were determined using quantitative real-time polymerase chain reaction. RESULTS:The serum levels of miR-141 were significantly higher in the patients with PCa compared to the patients with BPH and the healthy controls (P<0.01).The level of miR-141 in PCa group obviously differed from that in BPH group and healthy control group with high diagnosis performance, with areas under the curve of 0.785 and 0.801, respectively. No statistically significant difference of the serum miR-141 levels between the patients with BPH and healthy individuals was observed (P>0.05).The serum miR-141 level was also found to be related to Gleason score, clinical stage and bone me-tastasis status of the patients with PCa (P<0.05), and the patients with higher Gleason scores had higher serum miR-141 levels.No relationship was detected between miRNA-141 level and the patient’ s age, biochemistry recurrence and serum prostate-specific antigen level (P>0.05 for all comparisons).CONCLUSION: Circulating miR-141 could serve as a non-invasive biomarker for prostate cancer diagnosis, staging and prognosis prediction.

Objective To investigate the relationship between expression of active form of caspase-3 and cell cycle in Fas-mediated apoptosis of B lymphocytoma cell line MML-1. Methods MML-1 cells were incubated with agonistic anti-Fas antibody for different time,and cell apoptosis was induced.Cell apoptotic rates were analysed by flow cytometry,and sensitivity of MML-1 cells to apoptosis was determined.The expression of active form of caspase-3 was analysed by double staining with PI-Triton X and FITC-active caspase-3.Cyclin A,B_1 and E were selected as cell cycle markers for S,G_2/M and G_1 phase of MML-1 cells,and the expression of active form of caspase-3 was detected by flow cytometry. Results The cell apoptotic rate reached 56% after induction by Fas for 6 h.After induction by Fas for 4 h,the active form of caspase-3 was mainly expressed in cells of G_1 phase,while rarely in cells of S and G_2/M phase.Cells with negative cyclin A and B_1 and positive cyclin E expressed active form of caspase-3. Conclusion The expression of active form of caspase-3 in MML-1 cells mediated by Fas might be cell cycle dependent.Cells entering into late G_1 and early S phase first express active form of caspase-3,and their sensitivity to Fas-mediated apoptosis is the highest.

AIM: To explore the influence of herbs (9602 prescription) on brain energy metabolism in cerebral ischemia reperfusion mice.METHODS: Ischemia reperfusion in cerebral injury model was duplicated in mice. Using nuclear magnetic resonance (NMR) and high performance liquid chromatography (HPLC), the brain metabolism were measured. The influence of 9602 prescription on cerebral energy metabolism in ischemia reperfusion mice model was dynamicly observed. RESULTS: Phase Ⅰ: The spectrum of NMR showed that after 10 min of ischemia, the PCr peak dropped significantly, while the Pi peak rose significantly in both the control and the “9602” group. There was no remarkable difference between the two groups. After reperfusion the PCr peak in the control group continued dropping slowly and remained at a low level (55.50?14.94) after 10 min of reperfusion, while after reperfusion the fallen PCr peak in the “9602” group started rising till 76.72?13.37 (P0.05). Phase Ⅱ: The HPLC showed that the cerebral energy charge values of the control group (0.1104?0.0343) were significantly lower than those of the “9602” group (0.2884?0.0552) and the sham-operation group (0.1846?0.0455) (P
