1.Evaluation on Physical Performance of the Patients with Lumbar Disc Herniation(review)
Chinese Journal of Rehabilitation Theory and Practice 2006;12(11):975-977
Physical performance is an ability with which the sufferers of lumbar disc herniation(LDH) achieve daily work and basic physical activity,including daily activities(such as the diverting movement from standing to sitting),functioning state of nerves and muscles,dailyworking ability and walking gait,etc.;abilities of body performance relative to pains,such as walking ten meters with loads,sit-stand test and Tread mill walk,etc.Most of current rehabilitation evaluation may be influenced by the subjective factors of the examinee or the examiner,but intelligent device for energy expenditure and activity(IDEEA) may be helpful to evaluate physical performance of the LDH patients in a complete,quantity-fixing,systematic and dynamic way.

The sfa1 gene encoded a bifunctional enzyme with the activities of both alcohol dehydrogenase and glutathione-dependent formaldehyde dehydrogenase in Saccharomyces cerevisiae.The gene disruption cassette produced by PCR using the same long oligonucleotides which comprise 19 or 22 nucleotides complementary to sequences in the templates(pUG6 and pUG66 marker plasmid)at 3' end and 45 nucleotides at 5' end that annealed to sites upstream or downstream of the genomic target sequence to be deleted.After two linear disruption cassettes with a Cre/loxP mediated marker were transformed into the cells of Saccharomyces cerevisiae YS-1,the positive transformants were checked by PCR to correct the integration of the cassette and concurrent deletion of the chromosomal target sequence.Once correctly integrated into the genome,the select marker can be efficiently rescued by transformating the plasmid pSH47 into YS-1 and inducing the Cre expression with a Cre/loxP-mediated marker removal procedure.The expression of the Cre recombinase finally resulted in the removal of the marker gene,leaving behind a single loxP site at the chromosomal locus.The diploid mutant YS-1-sfa1 was generated,which could enhance the output of ethanol with 8.0% by shaking culture in flask compared with the original strain YS-1.

[Objective] To investigate the effect of Shangke Quyu Tablet (a formula modified from Tao Hong Siwu Decoction) in treating acute traumatic swelling and pain of soft tissue. [Methods] Two hundred and forty-six cases of traumatic injury in four limbs, which were classified to Qi-stagnation and blood-stasis syndrome, were randomized to two groups. After given fracture reduction and dislocation fixation, group A (n = 164) was treated with self-prepared Shangke Quyu Tablet and group B with Tongxuekang Capsules (n = 82) . Therapeutic effect was evaluated after 10 days of treatment. [Results] In group A, 116 cases were markedly improved, 30 much improved, 14 improved and 4 ineffective; in group B, 44 cases were markedly improved, 18 much improved, 16 improved and 4 ineffective. The therapeutic effect in group A was better than that in group B (P

Honeysuckle flower is a traditional herbal medicine in China Through systemically sorting and studying literature of Chinese medicine, this article pointed out that leech used by the traditional Chinese medicine in ancient time has the features of twist vine, slight purple stem with clothing hair; opposite growing leaves, ovule shape with clothing hair on both side; two flowers growing from one pedicel, labiate corolla with 3.2 cm longth, flower grows from white color to yellow color, each branch axil grows only one pedicel, the involucre is ovoid shape, and the flower season is from mid-March to mid-May. Among all species of caprifoliaceae, only Lonicera japonica Thunb. meets these botanic features. Therefore, L. japonica Thunb. should be used as the orthodox species of herbal honeysuckle flower.

1.6 kb ?4-desaturase gene(FAD4)was amplified by PCR using plasmid pGEM-TFAD4 as template.The fragment was subcloned into the HindⅢ/XbaⅠrestriction site of pYES2.0 vector.Recombinant plasmid pYFAD4 was transformed into Saccharomyces cerevisiae strain INVScl for expression.It was found to exhibit ?4-fatty acid desaturase activity in the recombinant S.cerevisiae YFAD4 in the presence of exogenous fatty acid substrate docosapentaenoic acid(100?mol/L)under introduction of GAL1.Expression of the FAD4 under appropriate media and temperature conditions led to the production of DHA and it reached 41.13% of the total yeast fatty acid by GC detection.It was suggested that the protein encoded by FAD4 could specifically catalyze DPA into DHA.

To improve ethanol production in Saccharomyces cerevisiae,an integration plasmid pUPGKAT with PGK promoter(phosphoglycerate kinase promoter),adh1 gene(the coding sequences of alcohol dehydrogenaseⅠ) and CYC1 terminator(Cytochrome c transcription terminator) was constructed.Firstly,a fusion fragment composed of PGK promoter and adh1 gene was generated by over lap extension PCR and ligated into pUG6 resulting in plasmid pUPGKA.Subsequently,CYC1 termi nator was amplified from pSH65 by PCR and ligated to the SpeⅠand SacⅡrestriction site of pUPGKA.To integrate PGK-adh1-CYC1 into S.cerevisiae genome,pUPGKAT was digested by TthⅢⅠand the lin-earized plasmid was used to transform S.cerevisiae YS2-△adh2(adh2 disrupted strain) by lithium acetate method.The yeast mutant YS2-△adh2-adh1 which had the adh1 gene placed under the PGK promoter and harbored the adh2 deletion was constructed.Anaerobic fermentation showed overexpression of adh1 by PGK promoter resulted in a 8.84% higher ethanol production compared to YS2-△adh2.

Acyl carrier protein is an essential component involved in the biosynthesis of DHA(Docosahexaenoic Acid) via PKS(Polyketide synthase) pathway,which takes the growing acyl chain from one enzyme to another.One cDNA clone,with high homology of ACP,was isolated from Schizochytrium sp.FJU-512 cDNA library.The deduced amino acid sequence contained 142 residues with isoelectric point of 5.04 and had the 4'-phosphopantetheine prosthetic(4'-PP) binding site.The target fragment was digested with BamHⅠ/HindⅢand inserted into the expression vector pET-30a resulting in the plasmid pET-30a/acp.The recombinant vector was transformed into E.coli BL21(DE3) and induced by IPTG.SDS-PAGE analysis demonstrated that ACP was effectively expressed.

Background Cellular autophagy is a non-apoptosis death form of tumor tissue.Research determined that arsenie trioxide (As2O3) leads to apoptosis of tumor cells.But whether As2O3 induce autophagy of SO-Rb50 cells or not is unclear.Objective This study was to assess the effects of As2O3 on autophagy of SO-Rb50 cells.Methods As2O3 with the concentration of 0,0.5,1.0,2.0,4.0 μmol/L was used to treat the SO-Rb50 cell line for 48 hours,and the growth and proliferation of SO-Rb50 cells were detected using MTT assay (A570).pGFP-LC3,a marker of autophagy,was constructed to transfer SO-Rb50 cells,and the cells were then divided into RPMI-1640 culture group (untreated group),As2O3 + RPMI-1640 culture group (As2O3 treated group) and rapamycin culture group (positive control group).Autophagy of SO-Rb50 cells was examined by laser confocal microscope and monodansylcadaverine (MDC) influorescence staining,respectively,48 hours following cell culture.Ultrastructural features of autophagy were examined with transmission electron microscope (TEM).The percentage of autophagy positive cells in different concentrations of As2O3 treated groups was calculated with flow cytometer.Results The A570 values of SO-Rb50 cells were 2.194±0.066,1.841 ±0.213,1.035±0.046,0.374±0.042 and 0.167±0.019 in 0,0.5,1.0,2.0,4.0 μmol/L As2O3 treated groups,with a significant difference among these 5 groups(F=547.636,P<0.05),and those of 0.5,1.0,2.0,4.0 μmol/L As2O3 treated groups were significantly reduced in comparison with untreated group (P =0.000).The positive granular spots for GFP-LC3 chimeric protein were seen to aggregate in autophagic vacuoles in the As2O3 treated group and positive control group,but diffuse cytoplasmic signal for GFP-LC3 was found in the untreated group.Normal ultrastructure of SO-Rb50 cells was exhibited in the untreated group,and many double-membrane-like bound vesicles and autlysosomes were documented in the As2O3 treated group and positive control group under the TEM.A lots of MDC fluorescence granule were found in the As2O3 treated group and positive control group rather than the untreated group.Flow cytometry showed that the percentages of SO-Rb50 cells were 0,15.6%,42.7%,57.9%,79.5% and 89.0% in the 0,0.5,1.0,2.0,4.0 μmol/L As2O3 groups and positive control group,respectively,showing a As2O3 concentration-dependent increase.Conclusions As2O3 can induce the autophagy of SO-Rb50 cells and inhibit the proliferation of SO-Rb50 cells.Autophagic response of SO-Rb50 cells appears prior to the nuclear change after exposed to As2O3.The degree of autophagy of SO-Rb50 cells is associated with As2O3 dose.
