Research on effective teaching influencing factors of basic courses of medical specialty in military university based on the Pharmacology / 中华医学教育探索杂志

The basic course of medical specialty is an important part of medical education. There are few studies on effective teaching of basic courses of medical specialty. Based on the course of Pharmacology, this paper discusses the connotation, influencing factors and strategies of effective teaching of basic courses of medical specialty. The factors influencing the effective teaching of basic courses of medical specialty are multiple, that mainly includes four dimensions: students, teachers, course resources and teaching environment. Strategies to improve teaching effect include strengthening the idea of education, positioning goals hierarchically, optimizing curriculum structure, and innovating education platform.

Preparation and Quality Control of Nifuratel Vaginal Effervescent Tablets / 中国药房

OBJECTIVE:To prepare nifuratel vaginal effervescent tablets(NVET)and establish a method for its quality control.METHODS:The NVET was prepared using acid or alkali effervescent by principal ingredient-separated granulation.The content of the principal ingredient was determined by UV spectrophotometry.RESULTS:The preparation was white or off-white colored tablet and its property was up to the standard stated in Chinese Pharmacopeia(2005 Edition)in identification and test.The linear concentration range of nifuratel was 100～400 ?g?mL-1(r=0.999 6)with an average recovery rate of 101.1%(RSD=0.62%,n=6).CONCLUSION:The preparation process for NVET is simple,and its quality is stable and controllable.

Design and synthesis of demethyl bryoanthrathiophene, a new potential angiogenesis inhibitor / 第三军医大学学报

Objective To design and synthesize a new potential angiogenesis inhibitor, demethyl bryoanthrathiophene. Methods Target molecule-demethyl bryoanthrathiophene was synthesized in 5 steps using 1,8-dihydroxy-9,10-anthraquinone as the starting material, 5,7-dihydroxy-1-carboxyl-6-oxo-6H-anthra thiophene as the key intermediate and decarboxylization as the key step. Results The target molecule was synthesized with a total yield of 10.1% and identified by MS, IR, UV, 1H-NMR, 13C-NMR and 2D-NMR. Conclusion Our synthesis of demethyl bryoanthrathiophene is based on an easily-acquired starting material and accomplished with a simple synthetic route.

Highly efficient synthesis of methyl bryoanthrathiophene-1-carboxylate / 第三军医大学学报

Objective To study the synthesis of methyl bryoanthrathiophene-1-carboxylate with high efficiency. Methods Target compounds were synthesized from 1,8-dihydroxy-9,10-anthraquinone via 5 steps including protecting, nitration, methyl mercaptoacetate substitution, intramolecular Aldol reaction and deprotecting. Results Target molecule was synthesized in the total yield of 45.8%. Conclusion Our synthesis of methyl bryoanthrathiophene-1-carboxylate is characterized by short synthetic route, high selectivity and high efficiency.

Application of Arginine-enriched Total Parenteral Nutrition in Surgical Nutrition Support / 中国药房

OBJECTIVE:To evaluate the effects of arginine-enriched total parenteral nutrition(TPN)on the nutritional and immune parameters of patients undergoing abdominal surgery.METHODS:67 patients undergoing abdominal surgery were randomly assigned to receive routine TPN(control group,n=24),TPN plus 15 g arginine(n=25,trial group Ⅰ)or TPN plus 30 g arginine(n=18,trial group Ⅱ)for 3 days postoperatively.RESULTS:Arginene-enriched TPN significantly improved postoperative nitrogen balance,promoted the recovery of plasma-albumin and total protein,and elevated the levels of CD4+ and CD4+/CD8+,but no significant difference was noted for immunoglobulin,complement C3 and complement C4 during trial period.CONCLUSION:Arginene-enriched TPN can improve patients' postoperative nutritional and immune parameters and enhance the efficacy of TPN support.
