Both Baicalin and Octreotide have obvious protective effects on the multiple organ injury in SAP with mechanisms associated to manifold factors. By comparing the pharmacologic effects of Octreotide and Baicalin, we believe that Baicalin as a new drug has a protective effect on multiple organs of a SAP rat model similar to that of Octreotide and is worth further study and development.

Through the addition of nano-silicon dioxide in the pure polyphenylene sulfide, the masterbatches were obtained, then using melt spinning technology to prepare SiO2/PPS fiber. The structure and heat-resistant properties of samples were characterized by transmission election microscopy (TEM), infrared spectrum (IR), differential scanning calorimeter (DSC) and other measurements. The experiment results indicate that the mechanical and heat resistance properties of PPS fiber were improved after adding the content of 1%wt nano-silicon dioxide. When the fiber was heated at 230°C for 24 hours, the breaking strength and elongation increased by 2.412cN/dtex and 11.90% compared to the pure PPS fiber. Moreover, the working temperature raised by 50°C.

Using the capillary rheometer to study the effect of shear rate, shear stress and temperature of Japanese and domestic PPS resin( fiber grade) on the apparent viscosity, index of non-Newtonian and viscous flow activation energy.The results show that with the increase of shear rate and temperature,compared to the domestic sample, Japanese sample has higher apparent viscosity, smaller non-Newtonian index(n),lower viscous flow activation energy,and smaller sensitivity to temperature.The Japanese specimens are suitable for processing and forming under high shear rate and spinning speed, but the domestic specimens are suitable for processing and froming under low shear rate and spinning speed.

Because of the hydrophobicity of PPS fiber,we used normal pressure air plasma treatment on PPS fiber with the rusult that the PPS fiber was modied and its hydrophilicity was improved effectively.The surface of PPS fiber was etched under the scanning electron microscope (SEM), observation. With the power and the time increasing, the water absorption of PPS fiber increased first and then decreased. However, to the breaking strength of PPS fiber, it was declined basically with the power increasing. Also, it had no great influence for the lasting of time.

Using capillary rheometer to study PPS temperature, shear rate, activation energy of viscous flow. Experiments show that with the increase of shear rate, apparent viscosity decreased. As the apparent viscosity is affected by temperature, so when the temperature increased, the apparent viscosity also decreased. It also indicates that the higher the shear rate comes, the lower the impact of temperature on the apparent viscosity is. As the temperature increased, non-Newtonian index (n) increased and tended to 1, PPS melt is pseudoplastic fluid. The activation energy of viscous flow of PPS decreased with the increasing of the shear rate. In addition, with the increasing of temperature, structural viscosity index felt regularly.
