RESUMO
Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.
RESUMO
Objective:To explore the effect of student standardized patients in experimental teaching of Internal Medicine Nursing. Methods:Totally 440 undergraduate students in Batch 2016 from the Nursing Department of Chengdu Medical College were divided into 9 groups with 5-6 students in each group. The situational teaching method of students' standardized patients playing clinical cases was adopted in internal medicine experimental teaching, and the teaching effect was evaluated by the questionnaire survey after the class.Results:More than 90.45% (398/440) of the students thought that this teaching method could enhance the ability of knowledge understanding and memorizing, 91.36% (402/440) of them thought that it could improve their corporation with classmates, 90.23% (397/440) of them thought that various abilities such as clinical thinking could be improved, and 87.27% (384/440) of them were satisfied with it.Conclusion:Applying standardized patients to the experimental teaching of internal medicine nursing is effective and can stimulate students' learning enthusiasm, thus improving the teaching effect.
RESUMO
Objective To explore the clinical characteristics,diagnosis and treatment of polycythemia vera(PV) transforming to acute myeloid leukemia(AML).Methods The clinical features and process of diagnosis and treatment in 4 cases of PV transforming to AML were analyzed.Results The case 1 had 10 years history of PV,after experiencing PV,had myelofibrosis and transformed to AML at the end stage of natural disease course;the case 2 had 7 years history of PV,orally took hydroxyurea(HU) treatment in recent 2 years and transformed to AML at present,his chromosome karyotype analysis showed 46,XY,del(7)(q31q36),del (18) (q22)[10],which was considered as treatment-related AML;the case 3 and 4 orally took H U for a long time after diagnosing HU,and respectively turned into AML during the pathologic polyemia stage after 6 and 7 years.Conclusion PV can be transformed to AML,the safety of HU in treatment should by paid attention to.
RESUMO
During the period of 11th Five-Year Plan,the Natural Science Foundation of China Peking University First Hospital acquired has improved in the total amount and project types.An analysis was made on the status of grant application and support in Peking University First Hospital as well as on the management method of the grant,offering some suggestions for the general hospitals on the management and development of Natural Science Foundation.
RESUMO
Based on the investigation of a hospital's grants during 2004-2005 and the authorized during 2002-2005 (385 in total), we tried to find the trends and bias of clinical sciences at present. We analysed on the types of grants (clinical or basic), research objects, experimental methods, discipline involved, modes of cooperation, and background of applicants. A close connection between research and clinical trial, interdisciplinary study, patient-centered practice and international competitions are becoming more and more important. To meet the needs of clinical research, policies and devotions such as technical platforms are needed.
RESUMO
Insulinoma-glucagonoma clone 20 can express at least 6 isoforms in human cells.These isoforms can affect cell apoptosis and proliferation through apoptosis related signaling pathway,such as TRAIL or TNF signaling pathways.Furthermore,insulinoma-glucagonoma clone 20,as a GTP-GDP exchange factor,participates in the transportation of nerve synaptophysins.
