OBJECTIVE To study pathogen distribution and susceptibility to sevenral antifungal agents.METHODS The CHROMagar candida color medium was applied to isolate and identify Candida strains.Drug sensitivity was analyzed by the K-B diffusion method.The drug sensitivity to econazole(ECO),nystatin(NYS),itraconazole(ITR),ketoconazole(KET),fluconazole(FLU),flucytosine(FCT),and amphotericin B(AMB)was tested.RESULTS Candida albicans was the most frequent isolated organism accounting for 62.5%.C.tropicalis and others accounted for 21.62% and 8.1%,respectively.The respiratory tract infection accounted for 76.57%,and the urinary tract was the second(6.31%),the blood and genitourinary tract were the third(5.00%).The susceptibility of Candada spp strains to nystatin and amphotericin B was more active than to other antifungal agents.CONCLUSIONS The fungal infection is relative to some risk factors,such as using antibiotics,underlying diseases and aging.Therefore,using antibiotics reasonably and improving the immunity are the main measures of preventing the fungal infection.

Objective To explore the role of eNOS and NF-?B in the cultured endothelial cells apoptosis induced by TNF-? and Ang II.Methods The cultured endothelial cells were treated with TNF-? and Ang II in absence and presence of PDTC(an inhibitor of NF-?B);the mRNA of eNOS was measured by RT-PCR,the protein of eNOS and I?B? were assessed by Western-blot,the activity of NF-?B was evaluated by EMSA,and the apoptosis of cells was detected with Tunel.Results The mRNA and protein of eNOS were significantly decreased in the endothelial cells induced by TNF-? and AngII(P

Objective To compare the diagnostic value of CT and NE for lesions of nasal cavity and paranasal sinus area.Methods 80 cases of nasal and paranasal sinus diseases which were examined by both CT and NE at same period and proved by pathology.were reviewed.Results Compare with results of pathology,the accucy rate of both CT and NE was identical in diagnosing sinusitis and tumours of paranasal sinus,NE was higher than CT in nasal and paranasal sinus polyp and nasal cavity tumour,turbinate hyperplasia CT was higher than NE in paranasal sinus cyst and anatomic variations.Conclusion Pathologic biopsy can be taken under NE guide to understand the shape,texture and colour of the illness focus CT can show the size,shape and anatomy relation between lesion and its neighbor tissue.The diagnosis may more perfectly through NE combined with CT.

Objective To explore the personality characteristics of abused children in order to reduce the incidence of child abuse.Methods Two hundred and ninty five middle school students were investigated with general questionnaire and Eysenck Personality Questionnaire of children. Eighty six students experiencing child abuse (CA) last year as study group and one hundred and ninety six non-abuse children as controls (NCA) were analyzed by means of Eysenck Personality Questionnaire of children.Results The score of neuroticism in CA group was significantly higher than that in the control group (55.62±10.60/52.65±10.98,t=-2.114 P=0.035). The score of lie in CA group was significantly lower than that in control group (42.21±9.87/46.04±9.20,t=3.184 P=0.002). On the impact of different sex, the psychoticism score of male was significantly higher than that in the control group(52.37±11.49/48.04±9.97,t=-2.227 P=0.028), and the lie score was significantly lower than that in control group(41.03±9.18/46.18±8.79,t=3.125 P=0.002).The scores of those in the female were not significant.Conclusions There is a close association between the unstable emotion and child abuse in children, so training emotional self-control and emotional expression of children might be a intervention strategy in the future. In addition, the frequency of lie in children is probably one of factors that determine whether children are abused or not.

Objective To compare the effects of equivalent dose sufentanil,remifentanil or fentanyl on hemodynamic and cardiac output in the elderly patients during induction of general anesthesia.Methods Ninety elderly patients(ASA Ⅰ ～ Ⅱ) undergoing elective abdominal surgery under general anesthesia were randomly divided into sufentanil group(group S),remifentanil group(group R) and fentanyl group(group F),30 patients in each group.Patients in group S,group R and group F received sufentanil 0.2μg/kg,remifentanil 2μg/kg and fentanyl 2μg/kg Ⅳ,respectively,using an blind method before intubation.SBP,DBP,MAP,HR,CO,CI and SVR were recorded before of anesthesia (T0),immediately after induction (T1),1,3 minutes after tracheal intubation (T2,T3).Changes of SBP and HR during observation were also recorded.Results The MAP and HR in three groups at T1 were significantly lower than those at T0 and decreased significantly in group R than those in group F and S(P ＜0.05).The MAP and HR in group F significantly increased at T1 than T0.The MAP and HR in group R were significantly decreased after tracheal intubation.Compared with the baseline,the MAP and HR in group S at T1,T2,remained unchanged.In group R,there were two patients whose HR were under 50 bpm.In group F,the MAP at T1,T2 were significantly higher than those at T.In group S,there were no significant changes in CO,CI,SVR which were all within normal range (P ＞ 0.05).Conclusion Both sufentanil and remifentanil effectively inhibit the stress response during induction of general anesthesia.At the same time,sufentanil has better hemodynamic stability.

Objective To explore the MRI features of ejaculatory duct obstruction.Methods During January 2003 to Dccember 2010,transrectal ultrasonography (TRUS) was performed for 106 patients and underwent surgical treatment for ejaculatory duct obstruction.Among them,16 patients underwent MRI examination.The MRI features of ejaculatory duct obstruction in these patients were summarized.Results Ejaculatory duct cysts,ranging in size from 4 mm ×4 mm ×7 mm to 4 mm ×4 mm ×9 mm and locating in the paramedian line,were detected in 5 of the 16 patients; ejaculatory duct dilation located in the paramedian line was detected in 7 patients,with the internal diameter of 5 to 30 mm. After contrast injection,significant enhancement of the wall of the ejaculatory duct was observed in 2 patients.Mullerian duct cysts complicated with dilated ejaculatory duct and seminal vesicles were detected in 4 patients,in whom the cysts were located in the median line,ranging in size from 4 mm × 5 mm × 6 mm to 34 mm×35 mm ×44 mm,with inverted teardrop shaped pointing toward the seminal colliculus.ConclusionThe most common MRI features of ejaculatory duct obstruction are ejaculatory duct dilation and ejaculatory duct cysts.

Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.

Objective To introduce the methods and key points for the external fixation combinel with limited percutaneous internal fixation plus colostomy in the treatment of open pelvic fracture concomitant with perineal laceration.Methods Nine patients with open pelvic fractures concomitant with perineallaceration were treated by external fixator combined with limited percutaneous internal fixer plus colostomy. Data including injury details, management and outcomes were collected for comparison.Results All the patients survived and attained bony union except for two patients with local infection that was healed several days after repeated wound debridement and use of wide spectrum antibiotics. All the patients had good extremity function at the latest follow-up. Conclusion External fixation combined with limited percutaneous internal fixation plus colostomy is a reliable, safe and less invasive procedure for the treatment of open pelvic fractures concomitant with perineal open wound.

Sensory, chemical, microbiological quality and bacterial flora on fresh Pseudosciaena crocea were qualitatively and quantitatively investigated. The results showed that total viable counts and total volatile basic nitrogen reached 5. 51?0. 25Log10cfu/g, 7. 84?2. 25mg/100g respectively. 279 strains of bacteria were isolated and 84.2% of them were gram negative bacteria, a small percentages of gram positive bacteria were detected (6. 1% ) . The predominant bacterial floras were composed of Enterobacteriaceae (14. 7% ), Aeromonas spp. (12. 5% ), Acinetobacter spp. (11. 5% ) and Moraxella spp. (11. 1% ) . A few percent of Pseudomonas spp. , Stenotrophomonas maltophilia and other bacteria were also found. The high number of Enterobacteriaceae showed that bacterial contamination on Pseudosciaena crocea, was mainly from cultural water field and polluted seriously by non-borne bacteria, and it should be paid attention to.
