  • Current Advances in Laparoscopic Splenectomy

    【Abstract】Objective To evaluate the operation of laparoscopic splenectomy(LS), its safety and clinical effects.Methods Literature of the advances of LS were reviewed and analyzed.Results With the development of technology and surgical technique, the indications for LS were widened, the size of spleen plays an important role in the clinical outcome of LS.Conclusion LS has all the advantages of minimally invasive surgery. The application of handassisted technique is safe and feasible for giant spleen. With the accumulation of surgical experiences and technique development, LS will be extensively used in clinic.

  • Effects of Endogenous Photodynamic Therapy on Intracellular cAMP and cGMP Concentrations of Human Colon Carcinoma Cell Lines SW480

    【Abstract】ObjectiveTo investigate the effects of endogenous photodynamic therapy (PDT) on intracellular cAMP and cGMP concentrations of human colon carcinoma cell lines SW480. MethodsSW480 cells were divided into control group, light group, δaminolevulinic acid (ALA) group (ALA group) and endogenous PDT group (ALAPDT group). Intracellular cAMP and cGMP concentrations of each group were detected by radioimmunoassay at 30, 60, 90 and 120 min after irradiation. ResultsThere was a significant increase in intracellular cAMP concentration of ALAPDT group at 30 min after irradiation (P<0.001) and sequent decrease, but intracellular cAMP concentrations of ALAPDT group at 60, 90 and 120 min after irradiation had no statistical difference than the other groups (Pgt;0.05). Intracellular cGMP concentration of different time point of each group was not significantly different. ConclusionThese results indicate that the cytoprotection of SW480 cell are produced by an instantaneous increase in the intracellular cAMP concentration while endogenous PDT is killing SW480 cell.
