Pancreatic cystic lesions are being recognized increasingly due to the development of computed tomography and magnetic resonance imaging.Differential diagnosis between pseudocysts and cystic tumors is the key point for pancreatic cystic lesions.Patients with pancreatic pseudocysts generally have a history of acute or chronic pancreatitis,whereas patients with cystic tumors did not have such a history.Some pancreatic cystic lesions did not have typical imaging presentations,and they were difficult to be diagnosed.Pancreatic cystic lesions could be divided into unilocular cysts,microcystic lesions,macrocystic lesions and cysts with a solid component according to the presentations under computed tomography and magnetic resonance imaging.This typing system is helpful for the diagnosis and differential diagnosis of pancreatic cystic tumors,as well as for the guidance of therapy.

Objective To evaluate the effectivness of photodynamic therapy (PDT) with chloroaluminum sulfonated phthalocyanine (CASPc) in B16F10 melanomas in a rabbit model. Methods B16F10 murine melanoma tumor fragments were implanted transclerally into the subchoroidal space of 38 immunosuppressed New Zealand albino rabbits and examined with indirect ophthalmoscopy and ultrasonography. When the tumors ranged from 2.0~3.8 mm in height, 30 rabbits were treated by PDT, with intravenous injection of CASPc 5 mg/kg, and irradiation at the wavelength of 675 nm of an argon-pumped dye laser after 24 hours. Light dose ranged from 20 J/cm 2 to 70 J/cm 2. The other 8 animals were treated with light only or photosensitizer only. The animals were followed up for 6~8 weeks. Results The 30 tumor-bearing rabbits were by PDT (laser and CASPc) regressed in 21 animals after treatment. At light doses under 40 J/cm 2, tumor regrowth was observed in 9 animals after two weeks of treatment. In all of the 8 control animals, the tumor-bearing eyes were filled with tumor at the third week after implantation with laser doses of 70 J/cm 2. Conclusion The study suggest that CASPc PDT may be effective in the treatment of B16F10 choroidal melanomas.

Objective Comparing the effects of steam sterilization on cyclic fatigue of stainless steel files. Meth-ods Fifty instruments of 25# stainless steel K files were randomly divided into 5 groups, which include 10 in each group. Group 1 was the blank control group, group 2 to 5 were subjected to 1, 3, 4, 5 steam sterilization cycles, then the files were tested by a custom-made device to assess cyclic fatigue and the number of cycles of failure (NCF) was calculated. Microstruc-ture of each file’s fracture surface was analyzed by Scanning Electron microscope (SEM). Results NCF in the 5 groups were 4 345.2 ± 384.2,3 937.9 ± 645.4,3 812.9 ± 532.5,3 626.2 ± 380.0,3 625.9 ± 565.6 respectively, and the differences among 5 groups were significantly different(F=2.598, P<0.05). After 4 or 5 times of steam sterilization, cyclic fatigue de-creased if compared with that in control group (P<0.05). Fracture surface in group 1 and group 2 was tough dimple structure and large numbers of regular, deep dimples were distributed on the surface. You could also see micro cavities clearly formed by fracture;Fracture surface in group 4 was dimple structure in brittle intergranular morphology. It is characterized by the presence of thin brittle precipitates, clean and smooth crystal interface, and a great sense of polyhedral stereo. Conclusion After 4 times of steam sterilization, cyclic fatigue strength of 25# stainless steel K files declined, which possessed the poten-tial risk of fracture.
