1.Compatible Stability of Pazufloxacin Mesilate for Injection with Three Kinds of Hemostatics in Sodium Chloride Injection
China Pharmacy 2005;0(20):-
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.
2.Precise mechanical analysis on the femoral three-dimensional finite element model constructed based on DICOM data
Chinese Journal of Tissue Engineering Research 2013;(30):5483-5489
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.
3.Application evaluation of procalcitonin in diagnosis of neonatal infection
Chinese Pediatric Emergency Medicine 2014;21(1):48-50
Procalcitonin (PCT) has been recognized a marker of infectious diseases for the past few years.The value of PCT is specific elevation in infectious diseases or inflammation caused by bacterial and it has an important role in the identification of bloodstream infections,bacterial and non-bacterial,rational usage of antibiotics and prediction disease prognosis.PCT is a high value diagnostic indicators.However,the PCT do not reflect a clear advantage in the diagnosis of neonatal infection.In this paper,the composition of the PCT,the source in the body of PCT,the metabolism of PCT,laboratory testing methods of PCT and its applications in neonatal infection were reviewed in order to gain a deeper understanding of the value of PCT in the neonatal diagnosis of infectious diseases.
