Objective To observe the effect of bilateral movement training on upper extremities dysfunction in stroke patients in convalescent phase. Methods 52 patients with hemiplegia were randomly divided into treatment group (n=26) and control group (n=26). The treatment group accepted bilateral upper extremities movement training, and the control group accepted routine neurodevelopment training mainly with affected upper extremities, for 6 weeks. They were assessed with Fugl-Meyer Assessment upper-extremity section (FMA-UE) and modified Barthel Index (MBI) before and after treatment. Results The FMA-UE and MBI scores improved in both groups after treatment (P<0.01), and improved more in the treatment group than in the control group (P<0.001). Conclusion Bilateral movement training may improve upper extremity function and activities of daily living more effectively for stroke patients in convalescent phase.

Hypoxia inducible factor 1 (HIF-1) is a heterodimeric transcription factor that plays an important role in oxygen homeostasis. In response to low level of oxygen, subunit HIF-1alpha expression is upregulated and transactivates its target genes essential for energy metabolism, erythropoiesis and vascular development. HIF-1alpha is thought to be able to protect hypoxic cells from apoptosis or necrosis under ischemic and anoxic conditions, the major trauma factors that affect the recovery of brain and spinal cord injury. Here we report the construction of recombinant adenovirus vector overexpressing HIF-1alpha intended for gene therapy against desired neuronal injuries. The recombinant vector could be packaged and yielded significantly high viral titers at 2 x 10(13) CFU in HEK293T cells and good expression levels of HIF-1alpha when superinfected in Hela cells.

To clone the 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (TwMCT) full length cDNA from Tripterygium wilfordii, the specific primers were designed according to the transcriptome data and the LCPCR were carried out. After a series of bioinformatics analysis on the TwMCT, the MeJA induced expression content were investigated by real-time fluorescence quantification polymerase chain reaction (RT-qPCR). The result showed that the full of TwMCTcDNA was 1 318 bp nucleotides encoding 311 amino acids. The molecular weight of the deduced TwMCT protein was about 34.14 kDa and the theoretical isoelectric point was 8.65. Result of the RT-qPCR analysis indicated that the content of TwMCT mRNA expression in T. wilfordii suspension cell was rising after treating with MeJA and reached the maximum in 24 h. Cloning and analyzing TwMCT gene from T. wilfordii provided gene element for studying the function and expression regulation of secondary metabolites.

Cannabinoid receptors are one of the most expressed G protein-coupled receptors in the central nervous system, which are potential drug targets for inflammation, pain and drug abuse. Cannabinoid receptors are composed of type 1 receptor (CB1R), type 2 receptor (CB2R) and other receptors, of which CB1R plays a vital role in regulating central memory, cognition, and motor function. Therefore, screening CB1R agonists has potential value in treating nervous system diseases. In this study, the intracellular loop 3 (ICL3) domain of CB1R was replaced with a circular-permutated enhanced green fluorescent protein (cpEGFP). After infecting HEK 293T cells with lentivirus particles, we obtained a stable cell line that was overexpressed human CB1R-cpEGFP after puromycin selection. The interaction between receptor agonists and CB1R led to the change of receptor conformation, resulting in de-protonation of the EGFP, and enhancing the fluorescence intensity. Therefore, active CB1R compounds could be verified by measuring the fluorescence intensity. Using CB1R agonist arachidonyl-2′-chloroethylamide (ACEA) as a positive control to evaluate the reliability of this model, studies have shown that ACEA could induce receptor activation and increase fluorescence intensity, while antagonist rimonabant inhibited receptor activation with unchanged fluorescence intensity. In conclusion, this study successfully constructed a fluorescent probe screening model for CB1R agonists.

Objective To investigate the value of diffusion tensor imaging (DTI) in evaluating the injury of corticospinal tract (CST), including the motor dysfunction and the integrity of CST, in patients with hypertensive intracerebral hemorrhage (HICH), and explore the relation between DTI results and the recovery of myodynamia. Methods Clinical data of 10 healthy volunteers and 35 patients with HICH, admitted to our hospital and performed evacuation of hematoma from November 2006 to May 2009, were retrospectively analyzed; DTI by using a 3.0T MR canner were chosen on them and the imaging was analyzed by Functool software. The changes of directionality and integrity of SCT were analyzed on fractional anisorropic (FA) map, color-coded directional map, and three-dimensional white matter tractography. Myodynamic examination at Brunnstrom standard 2 months after rehabilitation nursing was performed in these patients. The correlation between the injured degree of CST and the recovery of myodynamia was analyzed. Results Fiber tractography derived from DTI was consistent with known white matter fiber anatomy in 10 healthy volunteers. Three patterns of corticospinal tract involvement were identified in 35 patients: the intact one in 11 patients (the ipsilateral corticospinal tract was almost the same as contralateral corticospinal tract), the partially damaged one in 18 patients (the ipsilateral corticospinal tract was less than 2/3 but larger than 1/3 contralateral corticospinal tract) and the almost completely damaged one in 6 patients (the ipsilateral corticospinal tract was less than 1/3 contralateral corticospinal tract). Different pattern had totally different clinical outcome and the intact one had a full recovery. The ipsilateral corticospinal tract showed significantly lower Brunnstrom scores of the upper extremities than the ipsilateral one (P<0.05); the Brunnstorm scores and the value of myodynamia among the 3 patterns were statistically different (P<0.05). The recovery of motor function was negatively correlated to the injured degree of CST (r=-0.931, P=0.000). Conclusion The DTI, offering the optimal visualization of white matter tracts can detect the injured degree of the corticospinal tracts and predicate the prognosis to some extent, thus, early evaluation of corticospinal tract injury based on DTI can provide predictive value for motor functional outcome in patients with HICH.
