AIM： To compare the treatment modalities for patients with massive pancreaticojejunal anastomotic hemorrhage after pancreatoduodenectomy （PDT）.METHODS： A retrospective study was undertaken to compare the outcomes of two major treatment modalities： transcatheter arterial embolization （TAE） and open surgical hemostasis. Seventeen patients with acute massive hemorrhage after PDT were recruited in this study. A comparison of two treatment modalities was based upon the clinicopathological characteristics and hospitalization stay, complications, and patient prognosis of the patients after surgery.RESULTS： Of the 11 patients with massive hemorrhage after PDT treated with TAE, 1 died after discontinuing treatment, the other 10 stopped bleeding completely without recurrence of hemorrhage. AIJ the 10 patients recovered well and were discharged, with a mean hospital stay of 10.45 d after hemostasis. The patients who underwent TAE twice had a re-operation rate of 18.2% and a mortality rate of 0.9%. Among the six patients who received open surgical hemostasis, two underwent another round of open surgical hemostasis. The mortality was 50%, and the recurrence of hemorrhage was 16.67%, with a mean hospital stay of 39.5 d.CONCLUSION： TAE is a safe and effective treatment modality for patients with acute hemorrhage after PDT. Vasography should be performed to locate the bleeding site.

The excitation functions were measured in the reaction of 27Al+27Al at incident energies from 114MeV to 127MeV in steps of 200keV. The detection angles were continuously covered from 10o to 57° in the laboratory system. The energy autocorrelation functions of the dissipative fragments were analyzed by using different approaches. The nonself-averaging oscillations in the excitation functions were considered due to the angular momentum coherence and damping of the coherent nuclear rotation. The damping results from a quantum chaotic motion.

The high-spin states in 197Bi are studied with the 197Re(16O, 6n) reaction, theenergies of 16O being between 85 and 105 MeV. In-beam measurements of γ-ray excitation func-tions, γ-γ-t coincidences and γ-ray angular distributions are performed with six BGO （AC）HPGe detectors and one intrinsic Ge planar detector. Eleven new transitions and three new iso-mers at 2089, 2357 and 1968+△keV with T1/2=19, 34±4, 9, 53, 4±20. 5 and 18. 04±3. 1 ns,respectively, are observed, and a level scheme established.
