Objective: To observe the effect of edaravone combining ulinastatin on brain protection in patients of type A aortic dissection (AAD) after total arch replacement. Methods: A total of 60 AAD patients with total arch replacement in our hospital from 2014-09 to 2016-01 were prospectively studied. Based on peri-operative application of edaravone and ulinastatin, the patients were divided into 2 groups: EU group: 1) the patients received ulinastatin 300000 U/8h and edaravone 0.5mg/Kg/12h from administration to 3 days post-operation, 2) during cardiopulmonary bypass, the patients received ulinastatin 300000 U/2h and edaravone 0.5mg/Kg; Control group, the patients had no such treatment.n=30 in each group. The following items were observed:①operative condition;②blood levels of speciifc brain injury markers as S-100 and neuron speciifc enolase (NSE) at different time points: beginning of surgery (T0), opening aorta clamp (T1), right after cardiopulmonary bypass (T2), entering ICU (T3), 24h post-operation (T4) and 3 days post-operation (T5); ③post-operative condition. Results:①Durations of operation, cardiopulmonary bypass, cardiac arrest and bilateral antegrade selective cerebral perfusion (BACP), the frequency of BACP and UACP (unilateral antegrade selective cerebral perfusion), the lowest rectal temperature and blood levels of S-100, NSE at T0 were similar between 2 groups.②Compared with Control group, EU group had decreased S-100 and NSE from T1 to T5,P<0.05.③The in-hospital and ventilation time, frequency of PND and TND, the patients with CSS score≥16 before discharge and the in-hospital death rate were similar between 2 groups,P>0.05. Conclusion: Edaravone combining ulinastatin had brain protective effect in AAD patients after total arch replacement;it may reduce blood speciifc brain injury markers while the clinical signiifcance should be further investigated.

Objective To estimate the application value of colony PCR in the detection of pathogenic filamentous fungi. Methods Colony PCR was established and performed to amplify the internal transcribed spacer (ITS) region of 19 species (strains) of filamentous fungus followed by sequencing analysis. At the same time, DNA extracts from 8 of the 19 species of filamentous fungus were subjected to conventional PCR. Hha I and Hinf I endonucleases were used for restriction fragment length polymorphism (RFLP) analysis of the conventional and colony PCR products. Comparison analysis was carried out between the colony and conventional PCR. Results Of the 19 strains, 16(84.2%) yielded positive results by colony PCR; sequence analysis of the PCR products of ITS region revealed a 96% - 100% similarity with the reference sequence (NCBI database)of corresponding fungi. The amplification product length and RFLP profile of these products from the 8 species of filamentous fungus, except for those from Aspergillus nidulans, were consistent between the colony and conventional PCR. Conclusions Compared with conventional PCR, colony PCR-based detection of filamentous fungi is easy to operate, time and labor-saving, with high accuracy and reliability, and can be applied to the rapid identification of filamentous fungi.

Objective To evaluate the in vitro activity of seven imidazole antifungals against clinical isolates of common Candida species.Methods According to the Clinical and Laboratory Standards Institute (CLSI) microdilution method M27-A3,the in vitro activity of luliconazole,ketoconazole,miconazole,econazole,clotrimazole,sertaconazole and bifonazole was determined among 183 clinical isolates belonging to 5 species of Candida.Results The minimal inhibitory concentration range was 0.03-8 (geometric mean:0.067) mg/L for ketoconazole,0.03-16 (geometric mean:0.071 ) mg/L for miconazole,0.03-8 (geometric mean:0.207) mg/L for econazole,0.03-8 (geometric mean:0.061 ) mg/L for clotrimazole,0.03-16 (geometric mean:0.187) mg/L for sertaconazole and 0.03 -＞16 (geometric mean:1.050) mg/L for bifonazole. Luliconazole exhibited a superior activity against the 5 species of Candida in vitro,with the MIC range being 0.03-8 mg/L,geometric mean MIC 0.087 mg/L,MIC50 0.06 mg/L and MIC90 0.5 mg/L,respectively.However,some Candida isolates were identified to be relatively insensitive to these tested antifungals,including luliconazole.Conclusion All the tested imidazole antifungals,except for bifonazole,show an excellent activity against Candida species in vitro,but there exist a few Candida strains with relative insensitivity.

[ ABSTRACT] AIM:To compare the differences of the genome-wide methylation levels and methylated regions be-tween nasopharyngeal carcinoma ( NPC) cells in the same genetic background but different radiation resistance ( CNE-2 cells and CNE-2R cells).METHODS:Using the method which was developed by Doctor Zhao Cun-you, based on using methyl-sensitive restriction enzyme to measure the genome-wide methylation levels.In addition, MeDIP-Seq was used to analyze the methylated regions in 6 gene functional elements, including the upstream 2k sequence, 5’ UTR, coding se-quence, intron, 3’UTR and downstream 2k sequence, between CNE-2 cells and CNE-2R cells.RESULTS:The genome-wide methylation level was approximately 30%lower in CNE-2R cells than that in CNE-2 cells.No obvious difference on the amount of genes and the coverage of the peak in the 6 gene functional elements was observed.However, the methylation pattern of plentiful genes had altered in the gene function elements.CONCLUSION:The genome-wide methylation levels and methylated regions between NPC cells in the same genetic background but different radiation resistance were quite dif-ferent, indicating that the DNA methylation may be associated with NPC radioresistance.
