Objective To analyze the main epidemiological characteristics of fungal infection in this hospital in the past 7 years,and to provide reference for clinical treatment and prevention and control strategies of fun-gal infection.Methods The fungal data and clinical data of related patients isolated from clinical samples in Peking Union Medical College Hospital from early January 2018 to the end of May 2024 were selected,and the main epidemiological characteristics of fungal infection in this hospital were identified and described through multi-angle statistical analysis.Results A total of 4 479 patients with filamentous fungal infection were en-rolled.The proportion of male patients[57.5％(2 576/4 479)]was higher than that of female patients[42.5％(1 903/4 143)],mainly distributed in internal medicine,Intensive Care Unit(ICU)and emergency de-partment,among which internal medicine accounted for the highest proportion[50.0％(2 241/4 479)].About 90.0％of the specimens were from the lower respiratory tract,in addition to specimens from skin and soft tis-sue,tissue,ear and blood culture.In terms of seasonal distribution,there are more patients in winter.The fun-gi were mainly composed of Aspergillus,Mucor,Cerdosporium,Fusarium and Penicillium,among which As-pergillus was the most abundant,accounting for 74.6％of the total.Aspergillus fumigatus was the most a-bundant Aspergillus,accounting for 42.5％of the total Aspergillus(1 418/3 340).Among the related infec-tions caused by mold,Aspergillus was the most common in the lower respiratory tract,accounting for 76.8％.Among them,Aspergillus fumigatus accounted for the highest proportion(33.6％).98.6％of the molds infected the ear were Aspergillus,of which Aspergillus niger and Aspergillus terreus were the most common.Skin infections are mainly caused by Sporothrix schenckii,Trichophyton rubrum,Microsporum ca-nis.The results of in vitro drug sensitivity test showed that the four common Aspergillus isolated in this hos-pital were sensitive to voriconazole,and amphotericin B had better antifungal activity against Mucorales in vitro.Conclusion Based on the main epidemiological characteristics of fungal infections in this hospital,it is recommended that special attention be paid to the admission of patients in the respiratory department during the peak infection period in autumn and winter.In the treatment of fungal infections in different regions and on different body parts,attention should be paid to the differences in the distribution of bacterial species.

Objective To explore the role of transvertebral transposition of the spinal cord in the treatment of the pa?tients suffering from angular kyphoscoliosis with neurologic deficit. Methods Twelve patients with at least 1 year follow?up, in?cluding 5 females and 7 males, suffering from neurologic deficit secondary to angular kyphoscoliosis underwent transvertebral transposition of the spinal cord and posterior correction from January 2005 to June 2013 were retrospectively analyzed. The initial age averaged 21±14 years. The etiologies of deformity were congenital kyphoscoliosis in 9 patients, idiopathic kyphoscoliosis in 3 patients. Preoperative spinal cord function graded by Frankel criteria was 3 cases of grade C and 9 of grade D. The initial major curve was 79.4°±16.2° with a global kyphosis of 68.3°±25.0°. The change of distance between spinal cord and canal on the convex side at the apex was measured on MR images to evaluate the efficacy of transposition;in addition, Cobb angle on coronal and sagit?tal plane was evaluated before surgery, on discharge and at the last follow?up. Results All patients were followed up for 2 years on average (1-5 years). The post operation spinal function evaluated by Frankel criteria were as follow:with grade C of 1 case, grade D of 4 cases and grade E of 7 (7 cases changed one grade, 1 case changed two grades, 4 cases did not change obvious). At the last follow?up, all the cases got obvious recovery of spinal function, with 1 case of grade C and 11 of grade D (10 cases changed one grade, 2 cases changed two grades). The distance between spinal cord and canal on the convex side at the apex changed from 11.9±6.4 mm to 9.8±6.9 mm. After surgery, the major curve improved to 39.3°±15.1° with 50.3%±20.5%correction rate, and the mean loss of correction was 6.1%±7.5%. The mean kyphosis was 41.3°±16.6°, demonstrating a 39.0%±13.0%correction rate im?mediately after operation, and showing 3.1%±4.2%correction loss at the final follow?up. No neurologic complications or no death occurred intra?and post?operatively. No screw or rod fracture, instrumentation loosening and pseudarthrosis were found during fol?low?up. Conclusion Transvertebral transposition of the spinal cord and posterior correction is a useful procedure for the recovery of neurologic deficit secondary to angular kyphoscoliosis, with good results of deformity correction.
