Objective To isolate and observe Pityrosporum yeasts from a patient with onychomycosis. Methods The involved nail specimens were investigated by means of culture, pathological and scanning electron microscopic examination and 20% KOH preparation. Results Physical examination showed that each finger and toe nail appeared brownish black, rough and thick, some of the fore part of the nail plate detached from the nail bed. Fingernail specimen's culture results showed that Trichophyton rubrum grew on Sabouraud's dextrose agar and Pityrosporum ovale grew on the medium containing rapeseed oil. The pathological examination revealed P.ovale yeast involvement in the fissure of the nail plate. Under the scanning electron microscopy, a lot of P.ovale yeasts with characteristic collarette structure inserted in the nail tissue was noticed. In the 20% KOH preparations of nail incubated at 56℃for 1h and stained with Quink Parker ink, spores and hyphae were identified morphologically with P.ovale and T.rubrum respectively. The patient received intermittent pulse therapy with itraconazole, the color of the nails became much brighter 1 to 2 months after the fourth cycle of therapy, but no further improvement was observed afterwards. P.ovale and T.rubrum grew again 6 months after treatment when the clippings of the fingernail were cultured. Conclusion This is the first document of onychomycosis related with P.ovale in China.

Objective To evaluate the prognostic value of white blood cell and hemoglobin in patients with acute aortic dissection(AAD).Methods White blood cell.hemoglobin and fibrinogen were measured in 42 AAD patients.The mortality during hospitalization was observed and the short-term prognosis in AAD patients was as-seased.Results There was 13 death during hospitalization.with the mortality of 30.95%.The value of white blood cell was higher in death group than in survival group[(13.73±6.91)×109>/L vs.(9.43±4.97)×109>/L.P< 0.05).The value of hemoglobin was lower in death group of than in survival group[(118.54±22.38)g/L vs. (131.72±18.17) g/L,P<0.05].There were no differences in the value of fibrinogen between the groups [(3.15±1.15)g/L vs.(3.48±1.24)g/L,P>0.05).The mortality in the group of elevated white blood cell(≥10.0×109>/L)was higher than that in the group of normal white blood cell(10.0×109/L)(41.18%vs.24%.P<0.05).The mortality in the group of decreased hemoglobin(≤110g/L)was higher than that in the group of nor-mal hemoglobin(>110 g/L)(50.00%vs.27.78%,P<0.05).Conclusion The value of white blood cell and he-moglobin could help to assess the short-term prognosis of patients with AAD.

Objective To observation the changes of left atrium and pulmonary veins(PV)in patients with atrial fibrillation(AF) by transthoracic two-and three-dimensional echocardiography. Methods Transthoracic echocardiography were applied in 126 patients,which were divided into sinus rhythm(SR) group(64 cases)and AF group(62 cases),AF group were further divided into two subgroups:the paroxysmal AF and non-paroxysmal AF group.Left atrial area(LAA),left atrial volume(LAV),left atrial diameter(LAD)were measured by 2-dimensional echocardiography imaging.PV diameters were measured by three-dimensional echocardiography. Results Compared with SR group,PV diameters were significantly increased in AF group(P＜0.05).In patients with AF,PV diameters in non-paroxysmal AF group were larger than paroxysmal AF group.The four PV diameters in SR,paroxysmal AF and non-paroxysmal AF group did not show statisticant difference(P＞0.05).Compared with SR group,LAD,LAA,LAV were increased in AF group.LAD,LAA,LAV were larger in non-paroxysmal AF group than SR group and paroxysmal AF group(P＜0.05).Conclusions Left atrium and PV dilate significantly in patients with AF,transthoracic echocardiography could be a non-invasive method to observe left atrium and PV.

Objectives To compare the difference between multipoint inoculation and routine method for isolation of pathogenic fungi from nail samples of onychomycosis,and to analyze the epidemiology of pathogenic fungi in those patients.Methods The nail clipping samples from each patient were inoculated onto the plates with Sabouraud's agar,Sabouraud's agar without cycloheximide and medium containing rapeseed oil,respectively,by an approach of at least seven inoculating points in each plate (multipoint inoculation),and onto medium slope in tubes with the same media as above mentioned (routine method).In the multipoint inoculation method,plates with more than 3 colonies were taken for further identification of pathogenic fungi based on morphological and biochemical properties.Results Based on the data from 150 samples of onychomycosis,significant differences were found between multipoint inoculation method and routine method (P

Objective To examine the distribution of Malassezia species in follicular contents and perifollicular superficial skin in patients with Malassezia folliculitis and search for its causative agent. Methods A total of 120 patients with Malassezia folliculitis were investigated. Follicular lesions at three different anatomic sites were selected in each patient. Perifolliclar superficial skin specimens were taken by sterile adhesive tape, and the follicular contents of the same follicle were taken by sterile haemostatic forceps. The above specimens were cultured respectively on media containing rapeseed oil. The isolated colonies were identified by their physiological and morphological characteristics. Results Out of 319 isolates obtained from the perifollicular superficial skin, 247 isolates (77.43%) were identified as M. sympodialis, 40 isolates (12.54%) as M. furfur, 27 isolates(8.46%) as M. globosa and 5 isolates(1.57%) as M. obtusa. Out of 314 isolates obtained from follicular contents, 252 isdates(80.25%) were identified as M. globosa, 57 isolates(18.15%) as M. sympodialis, 4 isolates(1.27%) as M. furfur, and 1 isolate(0.32%) as M. obtusa. There was statistical difference in species distribution between the follicular contents and the perifolliclar superficial skin (P

Objective To study the clinical effect of continuous central venous pressure monitoring and select a better method for central venous pressure momtoring. Methods Continuous central venous pressure wag monitored by connecting pressure sensor to central venous catheter in 56 patients with open heart operation.At the same time routine monitoring method was used in the same central venous vein of the saine patient The CVP values from the two methods were compared for 100 times and analyzed the difference.Results The VCP values of the two groups had no statistical difference(P＞0.05).Conclusions Continuous monitoring by pressure sensor had advantages such as continuous data,dynamic,direct-viewing,Veracious and decreased chance of infection.It could reduce the workload of nurses and possessed more clinical value compared with routine monitoring method.

Objective To assess the prognostic value of tissue Doppler imaging(TDI) parameters in aeute myocardial infarction(AMI) patients. Methods After one week of AMI,102 patients underwent twodimensional/Doppler echocardiography and TDI examination.Early and late transmitral flow velocity E,A,deceleration time(DT)were measured. The average velocity of mitral valve at septal and lateral weremeasured including the systolic velocity(Sm),early diastolic velocity(Em)and late diastolic velocity(Am),Em/Am,E/Em were calculated.After 1 year follow up,the patients were divided into two groups according to whether hospitalizated due to heart failure(HF)or not. Stepwise multivariate COX regression analysis was used to identify the predictors of the cardiac event. Results In patients with H F,Sm,Em were lower than those of no HF group(P＜0.05),E,E/Em were higher than those of no HF group(P＜0.05 and0.01 respectively). Stepwise multivariate COX analysis identified that the E/Em was the only independent predictors of HF.E/Em≥12 was a useful HF predictors with a sensitivity of 84.2%,specificity of 77.1%.Conclusions E/Em ratio may assist in the risk stratification in AMI,and is a powerful predictor of HF.
