Objective To explore the ameliorative effects of standardized tertiary rehabilitation(STR)on the quality of life(QOL)of stroke patients with hemiplegia.Methods Eighty-two stroke patients were randomly divided into two groups:a rehabilitation group(R group)and a control group.All patients were given routine inter- nal medicine treatment,but STR was also administered to the R group.The QOL of all of the patients was assessed with the brief scale of quality of life(QOL-BREF)at the beginning,and at the end of the Ist month,3rd month and 6th month after stroke.Results There were two deaths in the control group,but no deaths in the R group.At ever- y stage,the R group returned better scores for physiological health,psychological state,social and environment rela- tionships,the subjective QOL and health items,and in comprehensive self-evaluation.QOL scores,except for social relationships,were consistently,significantly higher in the R group.The R group's QOL scores improved obviously in the first 3 months after stroke,and then more slowly in the next 3 months.Conclusions STR markedly improved the QOL of stroke patients.Their QOL scores improved obviously soon after stroke,but slowly later on.

Objective To examine the reliability,validity and sensitivity of FCA for stroke patients. Methods A total of 82 patients with stroke were divided into a treatment group and a control group randomly.The patients in the control group were given routine internal medicine treatment,while those in the treatment group were given standardized rehabilitation therapy in addition to the routine internal medicine treatment.All patients were as- sessed with FCA and Modified Barthel Index(MBI),at admission and the end of the 1st month,3rd and 6th month,respectively after the onset of stroke.The internal consistency,split-half reliability,content validity,crite- ria validity and sensitivity of FCA were tested.Repeat measure ANOVA and correlation analysis were used in the statistical analysis.Results There existed a good internal consistency(Cronbach?=0.901～0.973)as well as a good split-half reliability(R=0.949～0.981)of FCA.There was a medium to strong correlation among the 18 items scores of the FCA and FCA scores(P

The deubiquitinating enzyme ubiquitin specific peptidase 15 (USP15) is regarded as a regulator of TGFβ signaling pathway. This process depends on Smad7, the inhibitory factor of the TGFβ signal, and type I TGFβ receptor (TβR-I), one of the receptors of TGFβ. The expression level of USP15 seems to play vital roles in the pathogenesis of many neoplasms, but so far there has been no report about USP15 in psoriasis. In this study, immunohistochemical staining of USP15, TβR-I and Smad7 was performed in 30 paraffin-embedded psoriasis specimens and 10 normal specimens to investigate the expression of USP15, TβR-I and Smad7 in psoriasis and to explore the relevance among them. And USP15 small interfering RNA (USP15 siRNA) was used to transfect Hacat cells to detect the mRNA expression of TβR-I and Smad7. Of 30 cases of psoriasis in active stage, 28, 24 and 26 cases were positive for USP15, TβR-I and Smad7 staining, respectively. The positive rates of USP15 and Smad7 were significantly higher in psoriasis specimens than in normal skin specimens (44.1%±26.0% vs. 6.1%±6.6%, 47.2%±27.1% vs. 6.6%±7.1%), and positive rate of TβR-I (20.3%±22.2%) in psoriasis was lower than that in normal skin specimens (46.7%±18.2%). There was a significant positive correlation between USP15 and Smad7 expression, and significant negative correlations between USP15 and TβR-expression, an I d between TβR- and Smad7 expression I in psoriasis. After transfection of USP15 siRNA in Hacat cells, the expression of TβR-mRNA was up I -regulated and that of Smad7 was down-regulated. It is concluded that USP15 may play a role in the pathogenesis of psoriasis through regulating the TβR-I/Smad7 pathway and there may be other cell signaling pathways interacting with USP15 to take part in the development of psoriasis.

Objective To study antimicrobial resistance and genotyping of methicillin-resistant Staphylococcus au-reus(MRSA). Methods A total of 967 no-repetitive strains of Staphylococcus aureus(S.aureus)isolated from a hospital between January 2014 and November 2015 were collected,antimicrobial susceptibility testing,mecA gene,and Panton-Valentine leukocidin gene(PVL gene)were detected;staphylococcal cassette chromosome mec(SCCmec)typing,multilocus sequence typing(MLST),S.aureus protein A(spa)gene typing,and S.aureus ac-cessory gene regulator(agr)typing were performed with multiplex polymerase chain reaction. Results Of 967 strains of S.aureus,210(21.72%)were MRSA;detection rate of MRSA from sputum specimen was higher than that of skin and soft tissue specimen(68.09% vs 1 1.83% ,P<0.05);vancomycin- and linezolid-resistant S.aureus strains were not found,susceptibility rates of MRSA to gentamicin,tetracycline,erythromycin,clindamycin,levo-floxacin,ciprofloxacin,moxifloxacin,nitrofurantoin,and rifampicin were all lower than those of methicillin-sensi-tive Staphylococcus aureus(MSSA),differences were all statistically significant(all P<0.05);antimicrobial sus-ceptibility rate of MRSA to compound sulfamethoxazole was higher than MSSA,difference was significant(P<0.05). Susceptibility rates of MRSA isolated from skin and soft tissue to gentamicin,levofloxacin,ciprofloxacin,moxifloxacin,and rifampicin were 86.90% -95.24%,while MRSA isolated from sputum were only 1.56% -15.63%.Of 967 strains of S.aureus,210 harbored mecA gene,10 harbored PVL gene,8(3.81%)of 210 MRSA strains weren't typed. The main types of MLST,SCCmec,spa,and agr were ST 239(n= 177 strains),type Ⅲ(n= 177 strains),t 030(n= 177 strains),and typeⅠ(n= 196 strains)respectively.Conclusion The main epidemic clone of MRSA strain in this hospital is ST239-MRSA-SCCmec III-t030,antimicrobial resistance is serious,monitoring on drug-resistant strains in hospital should be strengthened.
