Objective To determine the effect of using cytomegalovirus-seronegative blood components in preventing transfusion-acquired cytomegalovirus infection,which laid foundation for the application of blood antibody screening of cytomegalovirus.Methods The documents of studies about the comparison in transfusion-acquired cytomegalovirus ratio between using cytomegalovirus-seronegative blood components with using cytomegalovirus-unscreened /non-WBC-reduced blood were retrieved from the databases of PubMed,MEDLINE,Ovid,ProQuest,EBSCO,Cochrane Library,EMbase,CNKI,VIP,CBM and WanFang Library,and the reference in studies were retrieved by hands at the same time.The documents were screened,extracted and evaluated according to inclusion and exclusion criteria,and then given a Meta-analysis by using Rev Man 5.1 software.Results There were totally 7 controlled studies(430 patients) included.The results of Meta-analysis showed that compared with using cytomegalovirus-unscreened/non-WBC-reduced blood,the effect of using cytomegalovirus-seronegative blood components in preventing transfusion-acquired cytomegalovirus infection had a statistical difference(OR=0.07,95%CI:0.03-0.18,P<0.01).Conclusion Application of blood antibody screening of cytomegalovirus is effective in preventing transfusion-acquired cytomegalovirus infection,especially organ transplantation and neonate patients.

ObjectiveTo investigate the effects of intramuscular Botulinum toxin type A (BTX-A) injection on spasticity of lower limb, walking and activities of daily living (ADL) after stroke. Methods13 patients with spasticity on lower limb were injected intramuscularly with BTX-A, and assessed with Composite Spasticity Scale (CSS), step length and gait velocity, and Barthel index (BI) before and 1, 4, 8 and 12 weeks after treatment. ResultsThe scores of CSS and BI significantly improved after treatment (P<0.05). There was some improvement in step length and gait velocity, but not significant (P>0.05). All the improvement appeared 1 week after injection and lasted to the 12th week. ConclusionLocal intramuscular BTX-A injection can reduce the spasticity on lower limb and improve ADL.

Objective To assess the efficacy of the mixtures of different concentrations of ropivacaine(R) and chloroprocaine(C)for epidural anesthesia in patients undergoing hysterectomy.Methods Sixty ASAⅠorⅡpatients aged 27-56 weighing 45-75 kg undergoing elective hysterectomy were randomly divided into 4 groups(n= 15 each);groupⅠ0.75% R alone;groupⅡ0.5% R-1% C;groupⅢ0.5% R-1.5% C and groupⅣ0.75% R+1% C.The epidural catheter was placed at L_(2,3)interspace and advanced 3.5 cm into the epidural space in cephalad direction.A total of 22 ml of epidural solution was injected in each group.The onset time,block height and duration of sensory block and the onset time,degree and duration of motor block(using Bromage scale)were assessed.The use of supplementary drugs(ketamine and ephedrine)and side effects were recorded.Results The onset time of sensory and motor block was significantly shorter in groupⅡ,ⅢandⅣthan in groupⅠ(0.75% R alone).The duration of sensory and motor block was significantly shorter in groupⅡandⅢthan in groupⅠandⅣ.The incidence of hypotension was significantly increased but the incidence of discomfort produced by traction on the viscera during operation was reduced in groupⅣas compared with groupⅠ.Conclusion The anesthetic efficacy of epidural 0.5% ropivacaine is significantly enhanced when mixed with 1.0% or 1.5% chloroprocaine.

[ ABSTRACT] AIM: To determine the aberrant methylation status in the gene promoter regions of CDH13, RASSF1A, DLEC1, SEPT9 and RUNX3 by detecting the plasma specimens and the value of their combined detection for di-agnosis of lung cancers.METHODS:Nest methylation specific PCR ( nMSP) was used to detect the promoter methylation status of the 5 genes in the plasma from 106 normal controls, lung cancer tissues, lung benign tissues and the plasma from 106 patients with lung cancers.Multiple displacement amplification ( MDA) was used to amplify modified genomic DNA to solve the problem of insufficient of plasma DNA template.RESULTS: The positive rates of promoter methylation of CDH13, RASSF1A, DLEC1, SEPT9 and RUNX3 in the lung cancer tissues were 51.9%, 44.3%, 54.7%, 36.8%, 24.5%, respectively, and those in the plasma were 46.2%, 41.5%, 50.9%, 31.1%, 19.8%, respectively.The re-sults of the Kappa consistency check showed that the lung cancer tissues and the plasma had obviously coherence in the methylation status of the 5 gene promoter regions.Combination of DLEC1, CDH13, RASSF1A, and SEPT9 had a higher di-agnostic efficiency than the others, as their ACC value was 0.8208 and youden index was 0.6415 ( with the sensitivity of 81.13% and the specificity of 83.02%) .CONCLUSION:Combination detection of promoter methylation of lung cancer-related genes in the plasma is expected to apply to the early diagnosis of lung cancer.

Objective To observe the changes of foot processes,expression and distribution of transient receptor potential cation channel 6 (TRPC6) in podocytes by puromycin aminonucleoside (PAN) and dexamethasone (DEX) intervention,then to investigate the function of TRPC6 in podocytes and its relation to proteinuria in kidney diseases.Methods Podocytes cultured in vitro were divided into three group:control group,PAN stimulation group and DEX intervention group.Mouse podocyte cell line (MPC5) were cultured in 0.02％ dimethyl sulfoxide (DMSO) in control group,subjected to PAN (50 μg/ml) treatment alone or with DEX (1 μmol/L) in other two groups for 8 h,24 h,48 h.The podocyte morphology was observed and took pictures by phase-contrast microscope,then the differences of morphology and areas were analyzed.The distribution,mRNA expression and protein expression of TRPC6 were detected by indirect immunocyto-fluorescence,real-time quantitative PCR and Western blotting,respectively.Results The well-developed podocyte arborization and interconnection was formed in control group,but PAN led to significant shrinkage of podocytes (P ＜ 0.05),together with podocyte foot process retraction,effacement and loss of cell contact.DEX significantly prevented the shrinkage and apoptosis of podocytes.The apoptosis rate was significantly increased after PAN stimulated 48 h (P ＜ 0.05).Real-time quantitative PCR and Western blotting found TRPC6 mRNA and protein expression were prone to increase in PAN group compared with control group (P ＜ 0.05).The distribution of TRPC6 becamed abnormal in PAN group.DEX decreased TRPC6 mRNA and protein expression at 48 h compared with PAN group (P ＜ 0.05).The abnormal distribution of TRPC6 was also alleviated by the protection of DEX.Conclusion DEX exerts a direct action to podocyte which retains the integrity of slit diaphragm against podocyte injury,and alleviates proteinuria via stabilizing mRNA,protein expression and distribution of TRPC6.
