Moral education and professional quality training remain important part of medical education and talent training. This article aimed to conduct a questionnaire survey on medical college students about their professional ethics status and school education in professional ethics, so as to explore the paths and measures of medical students' professional ethics education. College education bears the primary responsibility for the medical students' professional ethics education, thus reasonable curriculum should be set up and teaching methods should be innovated; Industry environment and social ethos also have important implications on medical students' professional ethics cognition and behavior, so it is necessary to regulate the behavior of the medical industry according to law; Information age requires correct public opinion by means of network guidance, and under the impact of the pluralistic culture and values, doctors need to adapt themselves to our excellent traditional culture.
ObjectiveTo study status-quo of humanity quality education of clinical medical postgraduates in China, provide ideas and suggestion for humanity quality education of medical postgraduates. MethodsGeneral evidence-based concepts and management research methods were applied. CNKI as well as other main official websites in China were searched to collect Chinese literature about humanity quality education of medical postgraduates. Then descriptive analysis was performed. ResultsA total of 62 studies were included. The results of qualitative analysis showed that, humanity quality education was not enough in class hours, category setting, demanding satisfaction, and actual effects. The effects of tutors did not effectively play in humanity quality education. General contents of humanity quality education were not the focus of education for clinical medical graduates. We should not easily replace humanity quality education evaluation with education assessment. ConclusionWe should improve humanity quality course setting, models and construction in humanity quality education of clinical medical postgraduates; take values, ideas, innovation and thinking capacity as content focus; consistently develop the style of humanity quality education; improve the effects of tutors on humanity quality education; and establish relevant complete effect evaluation system.
ObjectiveTo investigate the diagnostic value of 18F-FDG PET/CT scan for fever of unknown origin. MethodsThe 18F-FDG PET/CT scan results and clinical data were analyzed retrospectively in 32 patients with fever of unknown origin examined between January 2011 and October 2013. Final diagnoses were determined with recognized diagnostic standard. Results18F-FDG PET/CT scan was able to detect the cause of fever precisely in 53.1% (n=17) of the patients and was helpful in 25 patients (78.1%). The final cause of fever was determined in 20 patients, including infection (40%), malignancy (10%), non-infectious inflammatory disease (40%) and miscellaneous causes (10%). True positive, false positive, true negative and false negative rate of the modality were 17.0%, 4.0%, 8.0% and 3.0%; and the sensitivity and specificity were 85.0% and 66.7%. Conclusion18F-FDG PET/CT scan plays an important role in the diagnosis of fever of unknown origin.
This research aims to construct a lentiviral expression vector carrying the extracelluar domain (ED) of human hepatocyte growth factor receptor (C-Met), and to express it in transfected 293T cells. The extracellular domain of C-Met was amplified by RT-PCR, ligated with lentiviral expression vector p RRL-CMV-ED, and then expressed in 293T cell line. The expressed protein was purified and identified by RT-PCR and Western blot. The enzyme digestion and sequence analysis showed that the lentiviral expression vector p RRL-CMV-ED was constructed correctly. The size of amplified genes was about 2 700 bp. The purified protein with Ni-affinity column was about 105 kD analyzed by SDS-PAGE. The Western blot and ELISA results showed that the expressed protein which could bind to HGF specifically was the extracelluar domain of human hepatocyte growth factor receptor. This research may lay a foundation for further study of anti-C-MET monoclonal antibody and neutralizing antibody.
ObjectiveTo investigate the surgical methods and effectiveness to use the iliac flap combined with anterolateral thigh flap for repair of the first metatarsal bone and large skin defect. MethodsBetween January 2013 and January 2016, iliac flap combined with anterolateral thigh flap was used to repair the first metatarsal bone and large skin defect in 9 patients. There were 5 males and 4 females, with a median age of 15 years (range, 10 to 60 years). The causes included traffic accident injury in 6 cases and crush injury of machine in 3 cases. The average time from injury to operation was 3 hours to 14 days (mean, 7 days). The size of skin soft tissue defect ranged from 10 cm×6 cm to 20 cm×10 cm. The size of first metatarsal bone defect ranged from 2 cm×1 cm to 5 cm×1 cm. The size of iliac flap was 3.0 cm×1.5 cm to 6.0 cm×1.5 cm, and the size of anterolateral thigh flap was 10 cm×6 cm to 20 cm×10 cm. The donor site was directly sutured or repaired by free skin graft. ResultsAfter operation, the composite flaps survived with primary healing of wound; the skin grafts at donor site survived and the incision healed by first intention. All patients were followed up 6 months to 2 years (mean, 1.6 years). X-ray examination showed that the bone healing time was 3.5-5.0 months (mean, 4 months). The flap had soft texture, good color and appearance. All patients could normally walk. According to the American Orthopaedic Foot and Ankle Society (AOFAS) standard, the foot function was excellent in 6 cases and good in 3 cases, and the excellent and good rate was 100% at last follow-up. ConclusionThe iliac flap combined with anterolateral thigh flap for repair of the first metatarsal bone and large skin defect is a practical way with good shape at one stage.
