Objective To investigate clinical effects of g rafting of vascular sural nerve.Methods From1998to 2003,97cases of the defects o f the distal ulnar artery and nerve we re repaired by grafting of sural nerv e with anastomosis of short saphenous vein.Results All the cases were followed up for 6to24months.They were e-valuated according to the modified S eddon rating system.The total excellent and good rate was 80.41%.The ex-cellent and good rate of the emergency cases was 89.74%,while the excelle nt and good rate of second operation was74.14%.Conclusions Grafting of sural nerve with anastom osis of short saphenous vein is an effective method to repair the defects of distal ulnar artery and nerve of the forearm,because the procedure is easy,the nerve and vein are widely available,and the nerve is th ick enough to be foldable.The artery can be repaired after reverse vascul ar anastomosis so as to improve the bloo d circulation of limbs and prevent nerve necrosis.[

Objective:To determine the incidence of adrenal incidentalomas(AIs) in patients with diabetes mellitus and the metabolism profiles.Methods:A total of 615 hospitalized patients with diabetes mellitus in the Department of Endocrinology and Metabolism of Peking University People′s Hospital from March 2020 to May 2021 were retrospectively included in this study. AIs were screened by unenhanced chest computed tomography(CT) retrospectively and subsequently confirmed by multiplanar reconstruction. Participants′ physical indicators, metabolic profiles, and adrenal function parameters were collected. Unpaired t test, Mann-Whitney U test, and Chi-Square test were adopted to compare the metabolism profiles between diabetes mellitus patients with or without AIs. Regression models were used to estimate the correlations between AIs and the metabolism profiles such as blood glucose, blood lipids, blood pressure, and the adrenal function parameters.Results:Twenty-seven out of 615 participants were detected with AIs(4.4%). Patients with AIs had higher body mass index, waist circumference, and hip circumference than patients without AIs [(29.4±5.1)kg/m 2vs(26.8±3.8)kg/m 2,P=0.018; (102.3±11.7)cm vs(95.8±10.3)cm, P=0.002; (107.3±10.1)cm vs(101.4±7.6)cm, P=0.008]. The levels of serum uric acid and urinary albumin/creatinine ratio were also significantly increased in patients with AIs [(409.6±118.1)μmol/L vs(357.4±100.6)μmol/L, P=0.009; 21.25(7.49, 180.24)mg/g vs 8.60(4.71, 34.56)mg/g, P=0.010]. Besides, individuals with AIs were also associated with a higher risk of co-existing hypertension( P=0.045). Conclusion:The incidence of AIs in patients with diabetes is 4.4%. The presence of AIs in patients with diabetes may associated with increased risk of obesity and hypertension.
