OBJECTIVE:To study compatible stability of pazufloxacin mesilate for injection with three kinds of hemostatics in sodium chloride injection.METHODS:The changes of the mixtures in appearance,pH values,insoluble particles and the content of pazufloxacin mesilate within 8 hours after mixing of pazufloxacin injection with etamsylate,Vitamin K1 or aminomethylbenzoic at 25 ℃ under natural illumination in a simulated clinical common concentration were followed.RESULTS:There were no significant change in the appearance,pH value and the content of pazufloxacin mesilate within 8 hours after mixing of pazufloxacin mesilate for injection with aminomethylbenzoic injection or etamsylate injection;when mixed with Vitamin K1,there were no significant change in the appearance,pH and the content of pazufloxacin mesilate within 2 hours,but the insoluble particles was found to be unqualified after 1 hour of mixing,and white precipitate appeared after 4 hours and the content of pazufloxacin mesilate decreased to some degree.CONCLUSION:The mixture of pazufloxacin mesilate for injection and etamsylate or aminomethylbenzoic was stable within 8 hours at room temperature.The mixing of pazufloxacin mesilate for injection with Vitamin K1 should be conducted with caution.

Objective To evaluate the effect of enteral nutrision (EN) containing dietary fiber complex (DFC) on intestinal mucosal barrier in rats with experimental colitis. Methods Ninety six SD rats were induced into ulcerative colitis by acetic acid enema.than were divided into 3 groups. The rats in group C received non-DFC nutrison, while the rats in group Tl or group T2 received soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) of the EN with different proportion (1:2 or 1:3, respectively). At the first-, third-,fifth- and seventh-day after the EN, the concentration of D-lactate and diamine oxidase (DAO) activity in plasma were detected and intestinal samples were obtained to observe the changes of intestinal mucosa. Results At the third-,fifth- and seventh-day,the D-lactate concentration and the DAO activity in plasma significantly reduced in group Tl and T2 when compared with group C (P<0. 05) , but there was no statistical difference between group Tl and group T2. The scores of histological damages of colon in the group Tl and group T2 decreased in comparison with group C at all time points (P < 0. 05). However, the scores of histological damages of colon significantly decreased in group T2 when compared with group Tl at day 5 and day 7 (P <0. 05). Conclusion EN containing DFC may reduce the intestinal permeability of colitis in rats, which has a protective effect on intestinal mucosal barrier. While different proportions of the SDF or IDF ratio result in different effects on the mucosal protection. This protective effect will be enhanced by increasing the ratio of IDF in a certain scale.

BACKGROUND:The finite element model has been developed from two-dimensional model to three-dimensional model, from linear model to nonlinear model. As the advantage of this method in the analysis of mechanical characteristics of the irregular objects, the finite element model has been widely used in the research of orthopedic biomechanics, especial y in the research of hip joint. OBJECTIVE:To analyze the stress state of human femur with finite element analysis method and to investigate a method that can rapidly construct femoral finite element model and precisely analyze the biomechanics. METHODS:Normal male femur was used as specimen for CT scan to obtain cross-sectional images of femur in each slice. Three-dimensional reconstruction was performed with DICOM data and MIMICS software, then the femoral three-dimensional finite element model was established with the finite element analysis ABQUS 6.8 software, and the stress distribution of the model was analyzed under loading condition. RESULTS AND CONCLUSION:Based on DICOM data, three-dimensional finite element model of femur was constructed more quickly and precisely. The models were divided into 38 636 nodes and 201 422 units. The model included the parts of cortical and cancel ous bone. The biomechanical test results were accorded with the previous results, so the model could objectively reflect the real femur shape and biomechanical behavior with high precision. The Mimics software provided a simpler and effective method for the construction of femur model and improved the efficiency of modeling, and the three-dimensional finite element model based on DICOM data was accurate in shape and can be used for the normal research on biomechanical behavior of femur. The stress distribution analyzed with ABQUS 6.8 software is consistent with the clinical observation.
