RESUMO
Leukemia is a hematopoietic hyperplastic disease with an increasing incidence year by year, involving bone marrow and lymphatic system. The disease is complex and a highly heterogeneous disease, including a variety of subtypes, with difficulties in treatment and a poor prognosis. Currently, retinoic acid and its derivatives, arsenic are commonly used in clinical treatment as leukemia cell differentiation inducers. However, their clinical range of treatment is mostly restricted to granulocytic leukemia, with a high price and certain toxic and side effects. With the development of molecular genetics, molecular biology, second-generation sequencing and other technologies, the etiology and pathology of leukemia has been significantly studied, but the specific pathogenesis of leukemia has still been unclear. With the further promotion of molecular targeted drugs, chimeric antigen receptor T-cell immunotherapy (CAR-T) and hematopoietic stem cell transplantation, although the treatment of leukemia has entered a new field, compared with traditional chemotherapy, these therapies have high costs, and the long-term efficacy is yet to be further confirmed. After years of basic research and clinical research, traditional Chinese medicine(TCM) volatile oil in the treatment of leukemia has made remarkable achievements. Essential oil can alleviate the toxic and side effect of chemotherapy drugs, effectively prolong or prevent the relapse of leukemia, inhibit the proliferation of leukemia cells, and promote the apoptosis of leukemia cells. In this paper, the authors reviewed relevant domestic and foreign literatures by literature tracking method, summarized the anti-leukemia mechanism of essential oil of TCM, analyzed the characteristics and existing problems of essential oil of TCM, and proposed the improvement direction, in order to provide reference for accelerating the research and development and innovation of essential oil in the treatment of leukemia.
RESUMO
Objective To discuss the application about the TPDS educational reform of molecular biology in the medical students. Methods Choose 2009 and 2010 7-year program students (174 person) of clinical medicine as the research object, achieve to TPDS teaching; Control group ( 2010 basic medicine and general medicine students , 2011 basic medicine and pediatric medical students (394 person) carry out general teaching model. Taking the students test scores as the main teaching effect evaluation index, the questionnaire survey as the supplement. Statistical analysis was carried out using t test analysis method. Results Molecular biology of the experimental group students scores (94.39 ±4.34)are significantly higher than that of the control group (85.1 ±8.77), and P<0.05. The questionnaire showed that more than 80%students improved themselves in the areas of self-study ability, information collecting ability, problem-solving ability, and team cooperation abilityafter the course of study. Conclusion TPDS educational reform isoptional for the cultivating applied talents, intend to stimulate students' autonomous learning ability, inspire students to independent analysis and solve problems, improve students' unity cooperation spirit and model the humanistic spirit.
RESUMO
It lists 3 misunderstandings in acupuncture moxibustion theory and clinical study for students of the major:(1) Bias on manipulation exercise,less attention on grasping combination of TCM and western medicine;(2) only pay attention on dimensional points and sides,neglect acupuncture angle and depth;(3) have misunderstanding to acupuncture moxibustion effect and no enough confidence on clinical acupuncture moxibustion.
