Objective To explore the feasibility and clinical result in reconstructing of femoral artery defects with external jugular vein graft. Methods Sixteen cases of femoral artery defects caused by pseudoaneurgsm resected were reconstructed with external jugular vein graft from June 2002 to August 2005. Results The limbs of all the patients were salvaged successfully.Thirteen patients were followed up from 1 to 24 months. Their dorsal arteries of foot pulsated well, and there was no pseudoaneurgsm broken or defect recurred. Femoral nerve injury was found in one case. Femoral artery continuity was detected under the color ultrasound Doppler in 6 cases. Conclusion Reconstructing of femoral artery defects with external jugular vein graft is feasible, the effect of which is sure. The shortcoming is that the scar on the neck affects appearance after resect of external jugular vein.

Objective To study the pathogens associated with infectious keratitis for early diagnosis and treatment.Methods This study was conducted with the patients with confirmed diagnosis of infectious keratitis in our hospital during the period from January 2011 through December 2015.The specimens from corneal ulcer were subject to bacterial and fungal culture.The pathogens and associated risk factors of infectious keratitis were analyzed retrospectively.Results Of the 1 046 corneal specimens,369 (35.3％) were positive for microorganisms.The most frequently isolated microorganism was fungal species (53.1％),followed by grampositive cocci (31.2％),gram-negative bacilli (11.1％),and gram-positive bacilli (4.6％).Of the fungal strains,most were Fusarium (69.4％),followed by Aspergillus species (21.9％).Coagulase negative Staphylococcus accounted for more than half (50.4％) of the gram positive cocci.Conclusions Infectious keratitis is primarily associated with fungal infection,especially filamentous fungus such as Fusarium.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.
