Objective:To investigate the effects of different local complications of acute pancreatitis (AP) on the microcirculation of multiple organs in the upper abdomen.Methods:A dynamic volume perfusion computed tomography (DVPCT) scan in the upper abdomen was prospectively conducted in 101 patients with AP and 24 patients with neither AP nor other obvious upper abnominal lesions diagnosed in People′s Hospital of Deyang City from April 1 to October 31, 2019, 86 patients with AP (AP group) and 21 controls (control group) were enrolled in the study. AP patients were divided into no local complications group (21 cases), acute peripancreatic fluid collection (APFC) group (19 cases), acute necrotic collection (ANC) group (27 cases), walled-off necrosis (WON) group (11 cases) and walled-off necrosis with infection (WONI) group (8 cases). The blood flow (BF) of pancreas, liver, spleen, two kidneys and adrenal glands was measured by deconvolution. The hepatic arterial perfusion (HAP), hepatic portal perfusion (HPP) and hepatic perfusion index (HPI) of each group were calculated by maximum slope. T test was used for statistical analysis. Results:The BF of pancreas, spleen and left adrenal gland of ANC group was (139.89±34.28), (141.42±47.85) and (107.87±26.41) mL·min -1·(100 g) -1, respectively, the BF of pancreas, spleen and left adrenal gland of WON group was (130.00±44.83), (106.12±38.16) and (98.38±41.39) mL·min -1·(100 g) -1 respectively, and the BF of pancreas, spleen and left adrenal gland of WONI group was (127.91±35.86), (102.09±23.73) and (105.66±27.01) mL·min -1·(100 g) -1, respectively, which were all lower than those of control group ((161.22±31.60), (174.00±62.73) and (134.53±36.36) mL·min -1·(100 g) -1), and the differences were statistically significant ( t=2.440, 2.043, 2.943; 2.296, 3.796, 2.548; 2.448, 4.479, 2.154; all P<0.05). The BF of left kidney cortex of WONI group was lower than that of control group ((247.44±39.32) mL·min -1·(100 g) -1 vs. (294.80±39.13) mL·min -1·(100 g) -1), and the difference were statistically significant ( t=2.910, P<0.05). The HAP of ANC group, WON group and WONI group was (18.63±9.54), (19.10±7.47) and (19.51±6.26) mL·min -1·(100 g) -1, respectively, and the HPI was (25.01±15.51)%, (45.98±31.42)% and (35.92±24.95)%, respectively, which were all higher than those of control group ((12.18±5.14) mL·min -1·(100 g) -1 and (13.44±6.49)%), and the differences were statistically significant ( t=2.997, 3.088, 3.235; 3.503, 3.397, 2.517; all P<0.05) . The HPP of ANC group, WON group and WONI group was (72.37±21.76), (48.83±35.10) and (57.55±29.45) mL·min -1·(100 g) -1, respectively, which were all lower than that of control group ((86.43±17.98) mL·min -1·(100 g) -1), and the differences were statistically significant ( t=2.391, 3.331 and 3.226, all P<0.05). The HAP and HPI of APFC group were both higher than those of control group ((18.67±10.24) mL·min -1·(100 g) -1 vs. 12.18±5.14) mL·min -1·(100 g) -1 and (23.75±20.41)% vs. (13.44±6.49)%), and the differences were statistically significant ( t=2.572 and 2.108, both P<0.05) . Conclusions:AP complicated with ANC, WON and WONI can reduce the BF of pancreas, spleen and left adrenal gland, and WONI can induce the decrease of BF of left kindney cortex. AP complicated with ANC, WON and WONI can increase HAP and HPI, but decrease HPP. Furthermore, AP complicated with APFC can increase HAP.

Objective To evaluate the value of MSCT and MRI in diagnosis of early postoperative complications of inguinal hernia repair (IHR).Methods Imaging and clinical data in 1 6 patients with early complications of IHR were analyzed retrospectively.Re-sults Among the complications,postoperative infection in 2 was found including incision infection in 1 and groin cellulitis in other 1. CT showed swelling abdominal wall and heterogeneous enhancement for incision infection,and inguinal mass,deep inguinal ring thickening,edema of residual sac with fluid and air collections for groin cellulitis.Seroma was found in 8,and CT and MRI demon-strated residual sac effusion,spermatic cord thickening and spermatic vascular tortuosity.Residual sac edema was found in 4,and CT and MRI showed thickening spermatic cord without effusion in residual sac or scrotum.Effusions between patch and anterior abdom-inal wall were detected by MRI in 2,one of which was accompanied by patch shrinking.Conclusion With specific clinical background for early complications of IHR,MSCT and MRI provide more anatomical information of inguinal region,which may contribute to di-agnosis and treatment of early postoperative complications.

Objective To explore surgical methods and their efficacy for post-traumatic Made-lung deformity complicated with dorsal or volar angulation in the adults. Methods Volar plate or exter-nal fixator, combined with the techniques osteotomy and bone grafting, were selected to treat adult pa-tients with post-traumatic Madelung deformity complicated with dorsal or volar angulation. The effects were preliminarily evaluated through comparing the volar tilting angle, ulnar inclination, radial shortening and the range of joint motion before and after the operation. Results All the patients were followed up for 6-27 months (mean 16 months). The volar tilting angle, radial inclination, radial shortening, range of joint motion of all patients were improved significantly (P<0.05). Conclusions For patients with Madelung deformity complicated with dorsal angulation, internal fixation of volar plate combined with volar osteotomy and bone grafting is recommended; while dynamic eternal fixator combined with combined with dorsal osteotomy and bone grafting is an ideal choice for patients with Madelung deformity complicated with volar angulation.

Objective To explore the effect of recombinant bovine basic fibroblast growth factor(rb-bFGF)combined with boric acid solution on vulval ulcer.Methods 64 patients with vulval ulcer were divided into two groupa randomly.33 patients( group A) with vulval ulcer was treated with rb-bFGF and boric acid solution locally,while the others (group B) accepted ultra-red rays.Before the different treatment above,metronidazole or clotrimasole was put into the vaginae of all the patients,which were given relative medicine according to etiopathogenesis.The two groups were treated continually for two weeks and then were examined.Results The effective rate in group A was significantly higher than that in group B,which was the same result as the ulcer heating time between two groups.Conclusion rb-bGFG combined with boric acid solution is an effective remedy for the treatment of vulval ulcer.
