Objective:To investigate the clinical value of tympanic membrane repairment with modified ear canal flap under endoscope. Methods:A retrospective analysis was conducted on the clinical data of 62 patients who underwent simple tympanic membrane perforation repair surgery in our hospital from August 2019 to January 2023. All patients were divided into two groups: 37 cases in the otoscopy group and 25 cases in the microscope group. The surgical duration, postoperative pain response, and postoperative tympanic membrane healing and hearing recovery were compared between the two groups. Results:Compared with the microscope group, the total surgical duration of the otoscopy group was significantly shortened[（70.4±13.2） min vs. （102.8±17.5） min, P<0.001], and there was a statistically significant difference in postoperative VAS pain score[（3.1±1.2） vs. （6.5±1.4）, P<0.001]. The two groups achieved tympanic membrane healing and no infection occurred after operation. There was no significant difference in postoperative hearing recovery between the two groups（P>0.05）. Conclusion:Modified tympanic membrane repairment through otoscope can greatly shorten the operation time and reduce the hospitalization cost, which is more suitable for the application of primary hospitals.

Objective To evaluate the effect of ameliorating the pancreatic microcirculation in the early stage on the patients with severe acute pancreatitis(SAP). Methods 84 SAP patients admitted from 1995-1998 and 1998-2001 were retrospectively analyzed. Routine united management were given to 44 SAP patients in the former period (FP)(1995-1998),and special regime aimed at improving the microcirculation and preventing cell Ca 2+ overload besides routine management were given to 40 SAP patients in the later period(LP)(1998-2001).Results Cure rate (85.0%) in FP group was significantly higher than that of LP group(68.2%)(P
