Objective To evaluate the curved cutter stapler in the anus-preserving surgery of low rectal cancer. Methods To retrospectively analyse the clinical data of the application of the Curved Cutter Stapler in the anus-preserving surgery of low rectal cancer from 2006 to 2008. Results All the eases of patients with low rectal cancer received the anus-preserving surgery,one of them occurred in sub-clinical small fistula who recovered by con-servative treatment,no anastomofic leakage and no local recurrence occurred,two patients were died in 12,14 months after surgery. Conclusion The Curved Cutter Stapler has an advangtageous position in the anus-preserving surgery of low rectal cancer, can increase the rate of the anus-preserving.

Objective To explore the principle of diagnosis and treatment of early postoperative inflammatory ileus. Method To retrospectively analyse the clinical data and treatment results of early postoperative inflammatory ileus. Results 15 cases after fasting, decompression, nutritional support, somatostatin and dexamethasone, and other conservative treatment were cured. Conclusion Early postoperative inflammatory ileus usually occurred in 2 weeks, has a typical performance of the obstruction, conservative treatment is effective.

Dental hard tissues lack the ability to self-heal. In dentin and cementum, hydroxyapatite (HA) can exist outside and/or inside collagen fibers. It is difficult to repair or regenerate HA with a highly ordered orientation in the presence of collagen fibers. At present, the biomimetic mineralization of dentin and cementum, mainly carried out by imitating its biological formation process and its physiological structure, can be divided into those originating from the fiber mineralization mechanism and those with HA as the main component. The materials used include natural materials such as demineralized dentin matrix (DDM) and calcined bovine hydroxyapatite (BHA), and synthetic materials such as polymer-induced liquid precursor (PILP) and synthetic HA. In the future, natural materials and synthetic materials should be combined for the restoration and regeneration of dentin and cementum by means of biomimetic mineralization of calcium phosphate released by remineralization solution-HA.
