ABSTRACT
Objective:To study the application of powder comprehensive properties characterization of cefuroxime axetil in batch changes .Methods:The stability and change of the powder before the batch change of cefuroxime axetil were measured by an FT 4 mul-tifunctional powder flow tester .The flow rate, compression rate, shear property, air inflation and air permeability were measured .The corresponding powder index was established .After the batch change , the above indices were detected to assess whether meeting the re-quirements.Results:The volume index of three batches of products after the batch change was within the optimal range .Conclusion:The batch changes of cefuroxime axetil have no effect on the smooth progress of cefuroxime axetil production , which provides a new rap-id verification method for preparation manufacturers .
ABSTRACT
In order to optimize the teaching process, improve the teaching quality and cultivate of emergency nursing talents with comprehensive quality, we systematically designed the teaching process of foreign body airway obstruction first aid. From the design ideas and curriculum innovation, we focused on the use of a variety of teaching methods, and we combined it with modern information technology, which demonstrated the practicability and operability of first aid skill. This teaching practice has proved that the systematically teaching reform design is helpful to improve the learning efficiency of nursing students and cultivate the comprehensive quality of students' emergency response ability.
ABSTRACT
Objective To explore the current situation of nursing students′ self-learning and its influencing factors in the western China.Methods Based on the method of proportion allocation in stratified random sampling,the self-made general questionnaire and Williamson self-directed learning rating scale(translated by Shen Wangqin)were used for questionnaire survey among full-time nursing undergraduates and junior college students in four universities.Results The self-directed learning ability of nursing students was in general at a medium level;and the dimensions with the highest score and the lowest score were interpersonal relationship skills and learning behaviors.The self-directed learning ability of top public university was better than that of basic public universities(P<0.01);and the degree of self-directed learning ability of nursing students who were girls,in senior classes,voluntarily choosing and showing interest in this major was higher than those of other students(P<0.05);the motivation,learning interest,self-directed learning time per week were positive factors,and the learning difficulties acted as a negative impact factor.Conclusion The main factors influencing the self-directed learning ability of nursing students include the grade,gender,the willingness to choose the nursing major,the degree of preference for the nursing major,learning motivation,and learning interest.
ABSTRACT
Objective:To detect the expression of Shank1 protein in renal cell carcinoma (RCC), to investigate its difference between the tumor and carcinoma adjacent tissue, and to analyze its correlation with RCC clinicopathological characteristics and prognosis. Methods:The renal carcinoma and carcinoma adjacent tissues of 120 patients were selected from Cangzhou Central Hospital and Ji'nan Central Hospital from May 2008 to December 2014. The expression level of Shank1 was determined by immunohistochemistry and Western blot. Statistical analysis was performed to determine the relationship between the expression of Shank1 and the clinicopathological features of RCC patients. Results:Results of immunohistochemistry showed that the expression level of Shank1 in renal cancer tissue was significantly higher than that in carcinoma adjacent tissue, and the difference was statistically significant (P<0.05). Western blot results showed that the expression level of Shank1 protein in renal cancer tissue was also significantly higher than in carcinoma adjacent tissue. Correlation analysis found that the high expression level of Shank1 in renal cancer tissue was not significantly related to gender, age, tumor size, and TNM stage, but was significantly associated with the histological differentiation of RCC (P<0.05). Conclusion:Shank1 is abnormal y expressed in RCC renal cancer tissues and is correlated with the histological differentiation of RCC.
ABSTRACT
Objective To investigate the expression of a proliferation-inducing ligand (APRIL) in urothelial carcinoma tissue and its clinical significance. Methods We investigated the expression of APRIL mR-NA in urothelial carcinoma tissue of 33 patients in urothelial carcinoma in Cangzhou Central Hospital from July 2013 to March 2015, Among of them, 23 cases of adjacent pericancerous tissues were detected by qRT-PCR. Immunohistochemistry and western blot were used to detect the APRIL protein expression level in urothelial carci-noma tissue and adjacent pericancerous tissues. We analyzed the relationship between APRIL expression and clinical pathology in patients with urothelial carcinoma by statistical methods. Results The qRT-PCR revealed that the expression of APRIL in urothelial carcinoma tissue was significantly higher than that in the adjacent peri-cancerous tissues (P 0.05). Conclusion The APRIL is a high abnormal expression in urothelial carcinoma tissues , and maybe related to the occurrence and development of urothelial carcinoma.
