ObjectiveTo investigate the effects of hand-arm bimanual intensive training （HABIT） based on the FITT-CORRECT principles on upper limb function and functional independence in children with spastic hemiplegic cerebral palsy. MethodsA total of 87 children with spastic hemiplegia were enrolled and randomly divided into an observation group （n=44）， which received HABIT based on the FITT-CORRECT principles， and a control group （n=43）， which received conventional HABIT. Both groups received intervention for 6 weeks. The quality of upper extremity skills test （QUEST）， peabody developmental motor scales-fine motor （PDMS-FM）， and the functional independence measure for children （WeeFIM） were administered before and after treatment. The root mean square （RMS） values of the biceps and triceps brachii during maximum isometric contraction of elbow flexion and extension on the affected side were also measured. ResultsBefore treatment， there were no significant differences between the two groups in QUEST， PDMS-FM， WeeFIM scores， or RMS values of the biceps and triceps during maximum isometric contraction of the affected elbow （P>0.05）. After 6 weeks of treatment， no significant change was observed in the RMS values of the triceps during elbow flexion in either group （P>0.05）. All other outcome measures improved significantly in both groups （P<0.05）. The observation group showed significantly greater improvements in dissociated movement and grasp scores of QUEST， grasp and visual-motor integration scores of PDMS-FM， WeeFIM scores， as well as RMS values of the biceps during elbow flexion and both the biceps and triceps during elbow extension on the affected side （P<0.05）. ConclusionCompared with conventional HABIT， HABIT based on the FITT-CORRECT principles is more effective in improving upper limb function and functional independence in children with spastic hemiplegia.

AIM:To investigate the role of minocycline on glutamate uptake in the periventricular zone and its putative mechanism after hypoxic exposure in neonatal rats.METHODS: A model of hypoxic-ischemic brain damage (HIBD) was developed by putting postnatal 1 d rat pups in 5%O2 for 3.5 h.The glutamate level in periventricular zone was measured by liquid chromatography coupled with tandem mass spectrometry assay ( LC-MS/MS) after hypoxic exposure for 4 h and 1 d.The dynamic changes of glutamate transporters EAAT1, and EAAT2 during developmental period in periventricular zone were determined by Western blot.Moreover, the expression of EAAT1, EAAT2, Iba-1, IL-1β, TNF-αand TGF-β1 was also detected by Western blot after hypoxic exposure for 4 h and 1 d in that region.The effects of mino-cycline on all parameters mentioned above were tested after minocycline treatment at the same time points and in the same region.RESULTS:After hypoxic exposure, glutamate level was increased, but it was decreased after minocycline treat-ment.EAAT1 and EAAT2 kept a low expression level at the first postnatal week, but a predominant elevation was found at the end of the second postnatal week.The expression of EAAT1, EAAT2, Iba-1, IL-1βand TGF-β1 was increased at 1 d after hypoxic exposure.EAAT1 and TNF-αexpression was significantly up-regulated, while EAAT2 was down-regulated af-ter minocycline treatment.CONCLUSION: Minocycline inhibits the increase in the glutamate level after hypoxia in periventricular region of the neonatal rats.The mechanism may relate to the selective regulation of glutamate transporters, rather than the inhibition of neuroinflammation in periventricular zone.

Objective To study the effect of unsaturated fatty acid of Pinus koraiensis on lipid metabolism in rats. Method Unsaturated fatty acid was extracted and concentrated from Pinus koraiensis by supercritical fluid extraction and urea inclusion method. 40 rats were divided into 8 groups randomly. Except normal control group, the other groups were fed high fat diet. Normal control and obesity control groups were fed i.g. normal saline,Seed oil control group was fed i.g. pine nut oil and the other groups were fed i.g. 0.4, 0.8, 1.2, 1.6 and 2.0 g/kg bw unsaturated fatty acid. Body weights were weighed every week. After 4 w, the rats were killed, the serum total triglycerides(TG), total cholesterol(TC), high density lipoprotein cholesterol (HDL-C) and hepatic lipase(HL), lipoprotein lipase(LPL), liver lipofuscin (LP) were assayed. Results Compared with obesity control group, the body weight, body fat ratio, serum TG, LP and TC level were reduced remarkably. HL and total lipase (LA) level enhanced remarkably. Conclusion The unsaturated fatty acid of Pinus koraiensis could enhance the lipid metabolism in obese rats.
