Motor imagery therapy is based on the theory of plasticity in the central nervous system. Movement with imagery improved reconstruction of damaged motor conduction pathway, and made restoration of central nervous system. Motor imagery adapts to recovery mode of stroke, and was proved to be effective on motor function when applied with physical therapy for stroke patients. This article would review its background, mechanisms, Methods and effects, etc.

AIM: To study the neuroprotective effect and molecular mechanism of progesterone on reperfusion injury following ischemia. METHODS: The rats with transient middle cerebral artery occlusion(MACO) was described by Zea-longa for 2 h and reperfusion for 24 h. 48 male rats were divided randomly into 6 groups that were the sham, ischmia/reperfusion (I/R), dimethl sulfoxide (DMSO), and posttreatment, pretreatment, pre+posttreament with PROG groups. The immunohistochemistry staining and TUNEL reaction were used to facilitate the quantities of p53 protein and apoptosis in the brain tissuses. RESULTS: There were 26.25? 3.54 cells in p53 immunostaining in the I/R group, 22.88? 3.52 cells in DMSO group, 15.00? 2.07 cells in the pretreatment group, 16.75? 2.60 cells in the posttreatment group, and 10.38? 1.69 cells in the pre and posttreament group. The number of apoptosic cells was 1.88? 0.25 in the sham group, 41.38? 3.85 in the I/R group, 38.13? 5.69 in the DMSO group, 22.88? 2.70 in the pretreatment group, 25.63? 2.93 in the posttreatment group, and 20.88? 2.30 in the pre+posttreament group. The difference among drug management groups(pretreament, posttreament, and pre+posttreament)and control groups(I/R, DMSO)was significant (P

Objective To research and develop the model of external reciprocating sports intermittent hypoxia box for rats. Methods Two animal cabins (28 cm?20 cm?15 cm) and one hypoxia chamber (80 cm?80 cm?60 cm) which covered each cabin in turn were developed. 4 male SD rats were placed in each animal cabin. The hypoxia chamber in which low O2 concentration was maintained with filling high-pure Nitrogen continuously, moved to and fro between two animal cabins, and driven by a servomotors. Two animal cabins were covered in turn by the hypoxia chamber and get the same low O2 concentration as in the hypoxia chamber. The goal volume fraction of oxygen in hypoxia chamber was (10?0.5)% and the time of unilateral movement from one animal cabin to another was 4 s, the cycle time of intermittent hypoxia was 180 s, the retention time was 86 s (including the hypoxia and normoxia time was 90 s respectively). The hypoxia chamber runs 8 h per day. The numerical value on artery blood gas of rats in which hypoxia chamber inside and outside was measured Results The reciprocating sports intermittent hypoxia chamber can be operated safely and reliably. The lowest PaO2 is (4.766? 0.536) kPa(or (35.75 ?4.02) mmHg) and the lowest SaO2 is 0.69 ?0.08 when the animal cabin in hypoxia chamber. Conclusion The chronic intermittent hypoxia model for rats is established by self-developed external reciprocating sports intermittent hypoxia chamber.

Objective To assess the effect of Lep d2 from Lepidoglyphus destructor as a vaccine for specific immunothera?py on murine model of asthma. Methods Thirty BALB/c mice(SPF)were randomly categorized into a PBS group,an asthma group,and a Lep d2 SIT group. The mice in the asthma group and Lep d2 SIT group were sensitized by intraperitoneal injection with extracts of dust mites on Days 0,7th,and 14th,while those in the PBS group were injected with PBS. From the 21st day, the asthma group and Lep d2 SIT group exposed to the extracts of dust mites were stimulated by aerosol inhalation for 7 succes?sive days. During the period of the 25th-27th Day,the mice in Lep d2 SIT group were injected intraperitoneally with Lep d2 al?lergen for SIT 30 min before nasal inhalation,whereas the PBS group and asthma group were treated with only PBS. Twenty?four hours after the final inhalation,all the mice were sacrificed,the bronchoalveolar lavage fluids(BALFs)were collected. The lev?els of IFN?γ,IL?5 and IL?13 in the BALF and the supernatant of splenocyte culture solution(SSCS)as well as the levels of spe?cific IgE(sIgE)and sIgG2a in the sera were detected by ELISA. The lung tissues of the mice in the above 3 groups were stained by haematoxylin and eosin(H&E)and observed by a microscope. Results The symptoms of acute asthma attack were observed in the mice of the asthma group and Lep d2 group,but not in the PBS group. The allergic inflammation changes in lung in the Lep d2 SIT group were significantly alleviated compared with those in the asthma group. The concentrations of IFN?γin BALFs and SSCS of the mice in the Lep d2 SIT group were significantly higher than those in the asthma group(both P<0.01),while the levels of IL?5 and IL?13 in the former group were significantly lower than those in the latter group(all P<0.01). Mean?while,the level of sIgE of mice in the Lep d2 SIT group was significantly lower than those in the asthma group(P<0.01),while the level of sIgG2a of mice in the former group was higher than those in the latter group(P<0.01). Conclusion Lep d2 allergen as a vaccine can alleviate the allergic symptoms in the lung of mice effectively after allergen specific immunotherapy.
