ObjectiveTo study the effect of early rehabilitation on disability of motion and cognition.Methods107 patients were randomly divided into two groups,rehabilitation group (51 cases) and control group (56 cases).Patients in rehabilitation group were given regular early rehabilitation,while all patients in both groups were given usual clinical treatment. The Barthel Index (BI), Fugl-Meyer Assessment (FMA), Mini-mental Status Examination (MMSE) were used to evaluate these two groups before and 3 months after treatment. ResultsAfter treatment, the scores of BI, FMA and MMSE were improved significantly(P<0.05) in rehabilitation group compared with that before treatment, so did that of BI, FMA in control group(P<0.05).The scores of BI、FMMS、MMSE in rehabilitation group improved significantly compared with that in control group(P<0.05).ConclusionEarly rehabilitation may obviously improve the motive and cognitive function and increase the quality of living of hemiplegia after stroke.

This paper reported a new type of amylase (neoamylase) secreted by a Bacillus strain ZX99. The enzyme was a kind of ectoenzyme that could catalyze starch into isomalto-oligosaccharide effectively, but could not act on pullulan as substrate. The strain Bacillus ZX99 was mutated by ultraviolet ray and a mutant strain BS3.232 was screened. The activity of the neoamylase produced from BS3.232 increased by 60% over that from ZX99 under the same conditions. The results of thin-layer chromatography of products from starch and pullulan catalyzed by the enzyme demonstrated that the enzyme was different from neopullulanase and can be used to produce isomaltooligosaccharide from starch, including isomaltose, panose, isomaltotriose, isomaltotetose.

OBJECTIVETo observe the clinical efficacy of TCM for reinforcing Shen and activating blood circulation to dredge Channels in auxiliary treating chronic aplastic anemia (CAA), and to explore its mechanism.

METHODSSeventy-nine patients with CAA were randomly divided into the treated group treated with TCM plus western medicine and the control group treated with western medicine alone. The clinical efficacy was observed and levels of plasma sFas and sFasL before and after treatment were determined by ELISA.

RESULTSThe basic cure rate and total effective rate in the treated group were 37.50% and 87.50%; while in the control group were 20. 51% and 61.54% respectively. Comparison between the two groups showed significant difference (P < 0.01). The sFas level was markedly lower in both groups before treatment, but after treatment, it got elevated in the treated group significantly (P < 0.05), as compared with that in the control group, the difference was significant (P < 0.01).

CONCLUSIONTCM is effective in treating CAA with less toxic and side-effect, the mechanism might be the inhibition on over apoptosis of hematopoietic cells in CAA patients through regulating immune function of organism.
