ABSTRACT
Objective To study the effect of comprehensive treatment in stroke unit on the cognition and life quality of patients with vascular cognitive impairment ( VCI) and also its effects on the mental state of their caregiv-ers. Methods Ninety-three persons with VCI were randomly divided into a control group ( n=44) and a compre-hensive treatment group ( n=49) after being admitted into the stroke unit. Both groups took routine basic drugs ( such as anti-platelet drugs, lipid lowering drugs, anti-hypertension drugs, huperzine-A tablets and Nicergoline tablets). The treatment group was additionally provided with limb movement rehabilitation training, social practice, cognitive training and health education. During the treatment, the treatment group's caregivers were also given health education about VCI and stroke, systematic rehabilitation knowledge and skills training and appropriate anti-depressant and anx-iety medication if need. Before the treatment, as well as 3 and 6 months after the treatment, the patients of both groups were evaluated using the mini-mental state examination ( MMSE ) , the Montreal cognitive assessment ( MoCA) , their ability in the activities of daily living ( ADL) was rated and Spitzer quality of life ( QLI) values were assigned. The caregivers were evaluated using the Hamilton depression scale (HAMD) and the Hamilton anxiety scale ( HAMA) . Results After 3 and 6 months of treatment, the average MMSE, MoCA, ADL and QLI scores of the treatment group had improved significantly and were then significantly better than those of the control group at the same time points. The average HAMD score of the treatment group was also significantly better. Conclusion Com-prehensive stroke unit therapy can improve the cognition and life quality of patients with vascular cognitive impair-ment. It can also improve the mental state of their caregivers.
ABSTRACT
In Candida albicans, adaptation to environmental pH is relevant to its pathogenicity. Calcium signaling pathway involves in many stress responses and often accompany with Ca2+ fluctuation. We constructed CCH1 and MID1 mutant strains and studied their effect on calcium influx and further investigated the regulation by Crz1p transcription factor. We used PCR-directed gene disruption to construct cch1delta/delta and mid1delta/delta null mutant. By using a flow cytometry-based method we monitored the free cytosolic Ca2+ levels under alkaline stress. Moreover, we constructed pPHO89-LacZ plasmids and by beta-Galactosidase assays, we analyzed the changes of LacZ activities after gene disruption. The results showed that alkaline stress induced calcium burst reduced obviously in cch1delta/delta and mid1delta/delta mutant strains, also for LacZ activities, and fully abolished in crz1delta/delta mutant strain. Finally, by realtime PCR, we confirmed the regulation role of Crz1p in CCH1 and MID1 genes but in a calcineurin independent way. Studies on the effect of calcium pathway on response to alkaline stress will provide an important theoretical basis for Candida albicans infection-oriented treatment and new drug targets.

Delta8 desaturase pathway, different from common delta6 desaturase pathway, is an alternate pathway of polyunsaturated fatty acids biosynthesis. Delta8-fatty acid desaturase is one of the key enzymes in delta8 desaturase pathway. Two specific fragments were separately cloned from genomic DNA and cDNA of Euglena gracilis by PCR with the primers designed according to the reported sequence. Comparison of the genomic and cDNA sequences revealed that there wasn't intron in this delta8-fatty acid desaturase gene. This gene has an open reading frame of 1 266 bp that encodes 421 amino acids. It is 6 bp longer than the reported gene sequence, and also showed certain difference from the reported sequence in the N-terminal. The recombinant expression plasmid pYEFD by subcloning delta8-fatty acid desaturase gene into the yeast-E. coli shuttle vector pYES2.0 was constructed and was transformed into the defective mutant INVSc1 of Saccharomyces cerevisiae by electrotransformation. The resulting strain YD8 harboring plasmid pYEFD was selected and was cultured in the induction medium with exogenous substrates omega6-eicosadienoic acid and omega3-eicosatrienoic acid for the expression of delta8-fatty acid desaturase gene. The results indicated that high level expressed As-fatty acid desaturase could convert omega6-eicosadienoic acid and omega3-eicosatrienoic acid to dihomo-gamma-linolenic acid and eicosatetraenoic acid with substrate conversion ratio 31.2% and 46.3%, respectively.

Delta5-fatty acid desaturase is the key enzyme in synthesis of arachidonic acid. Two specific fragment was cloned from genomic DNA and total cDNA of Phaeodactylum tricornutum through PCR with primer designed according to the reported sequences, respectively 1520 bp and 1410 bp. Comparison of the genomic and cDNA sequences revealed that the delta5-fatty Acid Desaturase gene from genomic DNA had an 110 bp intron. The 1.4 kb was subcloned into the yeast-E. coli shuttle vector pYES2.0, then an expression recombinant plasmid pYPTD5 containerizing target gene was constructed. The plasmid pYPTD5 was transformed into defective mutant INCSc 1 of Saccharomyces cerevisiae for expression by electrotransformation method. Dihomo-gamma-linolenic acid was provided as an exogenous substrate to the yeast cultures, with galactose as inducer. By GC detecting, the recombinant S. cerecisiae had arachidonic acid. The results indicated that high level expression of delta5-fatty acid desaturase, and the substrate conversion reached 45.9%.

By constructing the genomic DNA library of Meiothermus ruber CBS-01, the genes of trehalose phosphate synthase (TPS) and trehalose phosphate phosphatase (TPP) involved in trehalose synthesis were cloned. The genes were cloned into the plasmid pET21a, and expressed in Escherichia coli Rosetta gami (DE3). The activities of these two purified enzymes were confirmed by thin layer chromatography (TLC). Meanwhile, we tested the cellular compatible solutes of M. ruber CBS-01 under different environmental pressure, and found that under hyperosmotic pressure, this strain can accumulate trhalose-6-phosphate, but not trehalose. These results can give more insight to future research in the roles of TPS/TPP and TreS pathway.

Microarray analysis revealed that the expression of ferric reductase (FRP1) can be regulated by the Riml01 protein. In order to find new transcriptional regulatory element in the promoter of FRP1, we analyzed the 1000 bp sequence upstream of ATG to find 2 potential Riml01p binding sites. We generated site-specific mutations in each of the two sites and fused these mutated promoters to LacZ. Then the promoter-LacZ fusion construct was recombinant into wild type and riml01-/- strains for beta-galactosidase assay. The results revealed that the FRP1 was up-regulated in alkaline pH and this was caused by iron starvation. The -650 site, not the -160 site, had an important role in FRP1 Riml01p-dependent expression. We conclude that Riml01p may interact with the -650 binding site of the promoter to regulate the FRP1 expression.
