BACKGROUND:Eucommia ulmoides gum has good thermoplastics, liquidity, bondability and antimicrobial properties. However, the application of Eucommia ulmoides gum as a root canal filing material is rarely reported. OBJECTIVE: To compare the different contents of gas phase nano-silica on mechanical performance of composite material taking the gutta-percha as the matrix, and observe the effect of the root canal filing. METHODS:Four kind of root canal filing materials were prepared through adding barium sulfate (20%), nano-hydroxyapatite (10%) and different contents of gutta-percha and gas phase nano-silica (40% and 15%, 45% and 20%, 50% and 25%, 55% and 30%). PureEucommia ulmoidesgum served as the blank control. The mechanical properties (hardness, tensile strength and rupture elongation rate) of those five materials were detected. Furthermore, four kinds of composite materials, pureEucommia ulmoidesgum and Gutta-Percha Pelets were filed into the fresh extracted premolar root canal by using Obtura II technology. The effect of root canal filing was observed under X-ray and scanning electron microscopy.RESULTS AND CONCLUSION: Along with the increase of the content of gas phase nano-silica, the hardness of Eucommia ulmoides gum composite material increased, tensile strength increased firstly and then decreased, and rupture elongation rate decreased. PureEucommia ulmoides gum was transmitted to the X-ray and no image of filing material was obtained. Four kinds of composite materials were resistant to X-ray, and images showed that al composite materials were equaly filed into the root canal, without cacuole, and were in contact with the root canal inner wal, showing good filing effect. Scanning electron microscopy showed that, fingerlike projections were the longest at the surface of pureEucommia ulmoides gum; as the content of gas phase nano-silica increased, fingerlike projection length reduced at the surface of composite materials.Eucommia ulmoides gum composite materials could be developed as a canal filing material under heat flow condition.

Objective To explore the value of trypsinogen activation pepfide (TAP) levels in blood plasma and urine in the diagnosis of acute pancreafitis at early stage and severity predicting combined with the CT results. Method Sixty-five patients with acute pancreatitis who scanned with enhanced CT were di-vided into mild acute pancreatitis (MAP) group and severe acute pancreatitis (SAP) group according to the CT results, 29 patients with acute abdomen except for acute pancreatitis were as control group. TAP levels in blood plasma and urine were measured in all patients. Results At the time of 6, 12 and 24 h after admis-sion, the level of blood plasma TAP in SAP group ( > 9.0 nmol/L) was significantly higher than that in MAP group(< 3.5 nmol/L), there were significant differences between SAP group and MAP group or control group (P<0.05). And the median urinary TAP in SAP group (102.8, 78.2, 52.3 nmol/L)was significantly higher than those in MAP group (32.5, 28.7, 25.6 nmol/L)and control group(12.6, 12.2, 11.5 nmol/L), there were significant differences among three groups (P<0.05). At the time of 3, 5 d after admission, there was no significant difference in TAP levels in blood plasma and urine among three groups (P>0.05). Conclusions Early dynamic detection of TAP levels in blood plasma and urine is of higher diagnostic value and predictive value for acute pancreatitis, which is of benefit in the early diagnosis and treatment of acute pancreatitis.
