Evaluation of pretreatment methods for filamentous fungal detection.

In order to obtain the best mass spectrometry identification results for using the most appropriate methods in clinical practice, we explore the optimal pretreatment methods for different species and morphologies of filamentous fungi. 98 fungal strains were treated with formic acid sandwich method, dispersion method, extraction method, and other methods using a medium element mass spectrometer (EXS3000) as a platform. Each strain had three targets, and the identification rates and confidence differences under different pre-treatment methods were compared to evaluate the identification effects of these methods.

[Influencing factors for the performance of trainees after hands-on training of endoscopic retrograde cholangiopancreatography].

Objective: To evaluate the performance of trainees after finishing hands-on training of endoscopic retrograde cholangiopancreatography (ERCP) at our hospital.

Methods: Questionnaire was distributed to 46 trainees of ERCP training over the past 5 years. And the effects of training duration, case volume and hospital facilities on ERCP performance were examined.

Postoperative endoscopic surveillance of human living-donor small bowel transplantations.

Aim: To determine the significance of endoscopic surveillance in the diagnosis of acute rejection after human living-donor small bowel transplantations.

Methods: Endoscopic surveillance was performed through the ileostomy after human living-donor small bowel transplantations. The intestinal mucosa was observed and biopsies were performed for pathological observations.
