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 study the difference in pathogenicity and genotype between two isolates of Veronaeae botryosa with different temperature tolerance. Methods Two strains of Veronaeae botryose were isolated from two patients with phaeohyphomycosis in Jiangsu and Henan province respectively. Of them, the Jiangsu strain could grow well at 37 ℃, but Henan strain could not grow at 36 ℃. Eighty mice were equally classified into immunocompetent and immune-suppressed (induced by cyclophosphamide) groups to be inoculated with the two strains of Veronaeae botryosa respectively. Ten mice remained uninoculated and served as the control. The general condition, growth and organic involvement of mice were observed for 4 weeks followed by the killing of surviving mice. Homogenated tissue samples were obtained from liver, spleen, lung, kidney and brain; then, tissue culture, direct microscopy and pathological examination were performed. Genomie DNA was extracted from tissue samples and subjected to random amplified polymor-phic DNA (RAPD) analysis. PCR was performed to amplify the intemal transcribed spacer (ITS) of rDNA followed by sequencing Results Systemic phaeohyphomycosis was induced in both immunocompetent and immune-suppressed mice by the Jiangsu strain of Veronaeae botryose; the mortality was 30% in immune-competent mice and 65% in immune-suppressed mice with statistical significance between the two groups. In immune-suppressed mice inoculated with the Jiangsu strain, the infection rate was 100% in the lung,signifi-cantly higher than in other organs; on direct microscopy the infection rate reached 64.7% in the liver, and 70.5% on tissue culture. There was no significant difference in the infection rate among these organs in immunocompetent mice inoculated with the Jiangsu strain, with the infection rate being 57.8% in the lung and 42.1% in the liver. Increased infection rate was observed in the lung of immune-suppressed mice com-pared with immunocompetent mice (P < 0.05). No definite infection was seen in immunoeompetent or immune-suppressed mice innoculated with the Henan strain. RAPD analysis and sequencing revealed that there was a base variation (A/G) at position 236 of ITS gene between the two strains. Conclusions The two strains of Veronaeae botryosa have different genotypes. Systemic phaeohyphomycosis can be caused in immunocompetent and immuno-suppressed mice by the Veronaeae botryosa isolate from Jiangsu Province; the mortality was higher in immuno-suppressed mice than in immunocompetent mice. The pathogenicity of Veronaeae botryose is associated with the immune status of hosts. In immuno-suppressed mice, lung is the organ most susceptible to infection by Veronaeae botryosa.

Objective To report a case of vaginal colonization due to Trichosporon inkin. Methods A 34-year-old female presented with increased vaginal discharge accompanied by abnormal odor for 2 months. Clinical laboratory examination was carried out. Cultures of vaginal discharge yielded yeast-like colony. Subsequently, the isolate underwent the following mycological examinations: purification, slide micro-culture, temperature test, urea enzyme test, biochemistry identification, antifungal susceptibility test, and gene sequencing. Results Gynecological examination revealed white homogeneous secretions attached to mucous membrane of the vagina. Nugent scores of vaginal discharge amounted to 5-6. Two rounds of culture of vaginal discharge resulted in stramineous, reductus and yeast-like colony. The isolate could grow in 42 ℃. Appressorium on the top of hypha and typical sarcinae formed in slide microculture of corn agar, and yeast malt agar was the optimal growth medium for it. Urea enzyme test was positive. API 20C AUX biochemical test and gene sequencing revealed that the isolate was consistent with Trichosporon inkin. The isolate was sensitive to amphotericin B and azoles such as clotrimazole and fluconazole, but resistant to flucytosine and caspofungin. Conclusions It is the first report of vaginal colonization due to T. Inkin in China. The accu-rate identification of T. Inkin relies on synthetic analysis of phenotype characteristics, biochemistry test and molecular sequencing.
