Objective To study the value of two-dimensional Echocardiography(2DE)and doppler tissue synchronization imaging (TSI) during early diagnosis of close myocardial contusion.Methods 9 small Guizhou-Panama pigs were used.The close myocardial contusion animal model was successfully established by using the serf made small impactor.Echocardiography wag applied before and after injury for 0.5,2,4,8 and 12h respectively,these data were analyzed together with the TYC pathological results.Results After the strike for 0.5h,the location and area of the damage call be directly and rapidly shown by 2DE and TSI,which showed that after myocardial contusion (MC),main damaged areas are anterior and lateral myocardial walls.After myocardial contusion MC,three echocardiography techniques were used to observe the scale of the abnormal segment,the movement of the myocardial wall,Time tO Peak of Systolic Velocity and wall motion segmental inter(WMSI),Time to Peak of Systolic Velocity index(TPI),which all were increased than that pre-injury.Conclusion 2DE and TSI can be used for accurately early diagnosis of the location of myocardial contusion.TSI is more specific for the diagnosis of myocardial contusion.

Objective To evaluate the two-dimensional strain by speckle tracking echocardiography in healthy piglets.Methods 9 small Guizhou-Panama pigs were used.High frame rate two-dimensional images were recorded from the left ventricular short-axis views at the levels of mitral annulus,papillary muscle and apex.Radial strain,circumferential strain and rotation were measured in the left ventricular short-axis views using two-dimensional strain software.Results Left ventricular two-dimensional radial strain gradually increased from the base to apex.As seenfromthe apex.LV performs a wringing motion with a clockwise rotation at the base and counterclockwise rotation at the apex.Conclusion 2DS technique is a rapid,accurate,easy,repeatable and no angle reliant method to quantitatively estimate the left ventrlcle function.

Objective To analyse CT diagnosis of unusual closed retroperitoneal trauma so that to improve its diagnostic accuracy.Methods CT features of unusual closed retroperitoneal trauma confirmed by clinical data and surgery in 13 cases were analyzed.Results There were adrenal hematomas in 11 cases,among them,2 cases accompanied with renal arterial occlusion,appeared as renal arterial ruptured suddenly and "interface sign".The hematomas appeared as round,similar round or mass hyperdense shadows and in combination with periadrenal tissue injury;pancreatic rupture in 2 cases,appeared as linear area of low attenuation inside pancreas.Conclusion CT scan is an effective modality for diagnosing the unusual closed retroperitoneal trauma.Correct CT diagnosis is very important for the effective surgical treatment as well as reduction of severe complications and mortality of unusual closed retroperitoneal trauma.

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 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.

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.
