ABSTRACT
Objective To evaluate comprehensive therapy in the treatment of keloid effect and the patients' satisfaction.Methods From 2002 to 2015,a total of 523 patients with comprehensive treatment,according to the treatment the patients were divided into group A (surgery combined radiotherapy group) and group B (operation with corticosteroid hormone therapy group),group C (corticosteroids in combination with radiotherapy group),and the therapeutic effect of patients with satisfaction was evaluate.Results Total effective rate of three groups of patients were 85.7％,84.0％,64.9％;the efficiency in group A was higher than that of group B and group C;there was statistically significant difference between group A and C (P＜0.05),but there were no significant difference between the group A and group B (P＞0.05).All the patients were follow up for one years and the adverse reaction in the three groups was slight and happened in the 2 month after cure.And the adverse reaction was all self-cure in the final follow up.Difference was statistically significant between three groups of patients' satisfaction,group B better than in group A and group C;there was no significant difference between group A and group B (P＞0.05);the difference between group B and C group was statistically significant (P＜0.05).Conclusions Three kinds of comprehensive therapy effect are obvious,among which surgical adjuvant radiotherapy effect is best,being worth to recommend for clinical use.
ABSTRACT
Transition metal oxide ZnO nanoparticles as inorganic matrix was adopted in the matrix assisted laser desorption ionization time-of-flight mass spectrometry ( MALDI-TOF-MS ) analysis of small molecule compounds including sugars and stearic acid and its performances were investigated. In addition, the feasibility of metal ion selective ionization of L-arginine by using NiO and CuO nanoparticles as matrix directly was explored initially. In the experiment, the analyte and nanoparticle suspension were mixed on the sample plate. The crystal of analyte and matrix was excited by 337 nm laser after the solvent was evaporated, and then detected under reflection mode of TOF-MS. The results indicated that ZnO nanoparticles with high UV absorption could eliminate the interference of conventional matrix, simplify the mass spectra, and enhance the peak intensity of stearic acid under negative mode. Moreover, Cu+ ion selective ionization of L-arginine was achieved in comparison of CuO and NiO as matrix for MALDI-TOF-MS analysis of L-arginine.
ABSTRACT
We innovated video assessment integrated teaching method on the basis of clinical case discussion,teaching rounds,problem-based learning,case method and micro teaching.According to this video feedback teaching,students became teaching subject and teacher acted as guide.In order to realize the purposes of early contact with clinical practice,more clinical practice and repeated clinical practice teaching,we implemented student-centered small class teaching,which was heuristic,inquisitive,interactive and was discussion-based.At the same time with the help of medical simulation equipment and video feedback teaching,this method developed students' life-long learning ability and work competence and combined theory with practice,demonstration with imitation as well as standards with innovation.This method was not only suitable for theoretical study but also for skills training,especially for standardization training.
ABSTRACT
Clinical teaching plan of pneumothorax and hemorrhagic shock was prepared with mind maps. The process of making this teaching plan was demonstrated as follows:relationship among all levels of subjects in this course was manifested by text and graph as belong and relevance. It is sim-ple, smooth, focused, lucid and easy to understand and remember. Application of mind mapis ex-tremely simple;it is suitable for medical education and is conducive to enhancing teaching efficiency.
