Objective To survey the current situation of teaching for general practitioners (GPs) in community health centers of Shanghai.Methods A questionnaire survey on the teaching situation was conducted among 742 GP mentors who attended a municipal training workshop during July to October 2012 in Shanghai.The items of the survey included general background,previous teaching experience and self-evaluation on teaching ability.Results Among 742 GP mentors receiving the survey,the average age was (37 ± 6) years old.49.8％ (366/734) of mentors expressed their willingness of teaching,and the main reason was that it may upgrade themselves,while learning from teaching (58.6％,419/715).Heavy work load,lack of teaching time (31.8％,378/1 187) and teaching experience (30.7％,364/1 187) were the main obstacles for teaching.Among 106 GP mentors who had teaching experience in community health center previously,79.2％ (80/101) made teaching plans,but only 8.9％ (9/102) often prepared syllabus.Teaching plans were made mainly according to the work needs in community health care (54.2％,52/96),the situation and demands students (29.1％,28/96) or requirement of syllabus (17.7％,17/96).The problems included lack of teaching experience (50.5 ％,50/99) and time (42.4％,42/99),monotonous instructional modality (24.1％,25/104),and weak operability of the syllabus (21.2％).The self-reported results showed that 14.4％ were not able to develop a teaching program and to execute,18.3％ were not able to use a variety of teaching methods,31.2％ were not able to engage in teaching for 1.5 days per week.Logistic regression analysis showed that mentors with higher education background (OR =2.027,P ＜ 0.05),community teaching experience (OR =3.069,P ＜ 0.05),higher self assessment of general personal quality and communication ability (OR =2.488,P ＜ 0.05),higher teaching ability (OR =2.399,P ＜ 0.05) and strong training wishes (OR =11.382,P ＜ 0.05) were more willing to engage in the teaching work.Conclusions Heavy work load,insufficiency of teaching capacity and experience are main problems for GP mentors in Shanghai community health centers.Educational theory and methods should be focus on teacher training so as to improve teaching abilities.

Objective To investigate the capacity and training needs of the community general practice mentors in different areas of Shanghai.Methods General practice mentors from community health centers,who attended a municipal training program in Shanghai during July 2012 to October 2012,were participated in the survey with a self-designed questionnaire.The general condition,basic ability (clinical skill,teaching ability and professional development),motivation and needs of training were investigated.The factors affecting the willingness of training were analyzed.Results Among 742 mentors receiving the survey,259 were from the urban area,174 from rural-urban continuum and 309 from rural area.The academic degree in urban group was relatively higher:17 out of 257 (6.6％) holding master degree.The ratio of participants who had received standardized training in urban,rural-urban and rural areas was 33.2％,25.3％,37.4％,respectively.The personal quality and communication skills in urban group were significantly higher than those in rural-urban continuum and rural group (18.58 ± 2.49,17.89 ± 2.69,17.85 ±2.34,P ＜0.05).The clinical skill (12.31 ± 1.98,11.95 ±2.02,11.52 ± 1.81),teaching ability (11.99 ± 2.62,11.63 ± 2.86,11.12 ± 2.77) and professional development (6.42 ± 1.61,6.36 ± 1.55,5.61 ± 1.38) in urban group were all significantly poorer than those in other two groups.The main purpose of participation in training was to improve medical knowledge and clinical skills in three groups (70.8％,74.0％,80.4％,respectively),followed by the need for community teaching.The rural group has higher training requirements in improving clinical diagnosis and treatment ability (75.3％,80.1％,85.5％,respectively in three groups),doctor-patient communication ability (38.0％,44.0％,50.7％,respectively) and community preventive care ability (29.4％,30.7％,42.8％,respectively).The urban group had much more requirements in scientific research training (38.8％,34.9％,14.1％,respectively).Logistic regression analysis showed that doctors with supports from the leadership (OR =2.688,P ＜ 0.05) and with less working stress (OR =2.241,P ＜ 0.05) were more willing to participate in mentor training.Conclusion There are discrepancies in basic ability and training needs of community general practice mentors in different areas of Shanghai,so we should develop specific or targeted training program in the future.

Objective To develop an index system for evaluation index system for community general practice teaching base.Methods A draft of evaluation index system for community general practice teaching base was preliminarily developed on the basis of literature research.Two rounds Delphi consultations with 32 experts of general practice were conducted between July 2014 and May 2015.The results of consultation were analyzed and the evaluation index system for community teaching base was established.Results In two rounds of Delphi consultation,the positive coefficients were both 100％,the authority coefficient of experts were 0.879 and 0.897,respectively,and the coordination coefficient were 0.165 and 0.204 (P ＜0.01).The established evaluation index system consisted of 4 first-class indexes,8 second-class indexes and 27 third-class indexes.Four first-class indexes were basic conditions,teaching conditions,teaching staff and teaching practice.Conclusion The established evaluation index system may be used to accredit community general practice teaching base and to improve the quality of general practitioner training.

ObjectiveTo understand the characteristics of mutations in BCR-ABL1 kinase domain mutation,these chronic myeloid leukemia (CML) and Ph positive acute lymphoblastic leukemia (ALL)patients who got imatinib treatment had poor effect.MethodsTotally 177 CML patients and 33 Ph( + )ALL patients were selected at Beijing Dao-Pei Hospital from Sep.2007 to Dec.2010.All of them were Chinese patients.Totally 243 bone marrow or peripheral blood specimens were collected from the patients,who had early effect,then resistance emergenced,or for more than 3 months of poor efficacy.Extracted total RNA from the specimens' nuclear cells,reversed transcription to cDNA.Amplified the whole span of BCRABL1 fusion kinase gene by nest PCR (from 242 to 493 amino acid coding sequence),used the type AB3130XL gene sequencing instrument determinate the gene sequence of ABL1 kinase region and then used the Variant Reporter V1.0 software to analyze the results of gene mutations.ResultsThirty-two kinds of different mutations were detected of ABL1 gene mutations,accounting for 34.2％ (83/243 cases).Among them,the T315I was 12％ (10/83),mutation rate was the highest,followed by Y253H was 11％ (9/83),G250E was 7％ (6/83),E255K was 7％ (6/83),M351T was 6％ (5/83),E459K was 5％ (4/83) ;Q252H,D276G,F317L,E355G,F359V,H396R were all 4％ (3/83).Three cases of insertion mutations were found,including 2 cases of 357-358insk,1 case of V304RfsX17.Seven patients had found existence two or more point mutations.The multiple drug resistance mutations might exist in the same leukemia clone.The same individual was not only contain common resistance mutations,but also rare point mutations,insertion mutations.The mutations might be lead to loss of kinase activity.ConclusionsUnder the imatinib drugs pressure,the ABL1 gene mutation in leukemia cells appears randomly,and results in different resistant clones.Different resistant clones can coexist in the same patients in vivo; resistant clones not only contain point mutations,but also contain inserted deletion mutations.

Objective To evaluate the effect of clinical competence training for general practitioners in Shanghai.Methods Total 759 general practitioners participated in clinical competence training from July 2011 to October 2012 in Shanghai.The theoretical and practical operation scores of all the 759 trainees were compared before and after the training and the influencing factors of training effect were analyzed.Results The trainees,including 260 (34.26％) males and 499 (65.74％) females,had average working experiences (13.6±7.1) years.The average total scores before and after training were(67.40 ±8.57)and (73.61 ±7.20) (t =17.96,P ＜ 0.01).The practical operation scores were improved more significantly,the average scores of physical examination before and after training were (12.90 ± 3.76) and (14.00 ±3.51),scores of clinical skill before and after training were (9.41 ±4.80) and (13.40 ±4.02) (t =6.31 and 19.01,P ＜ 0.01).Among seven items of physical examination test,scores of four items (cardiopulmonary examination,abdominal examination,neurological examination and thyroid examination) were significantly higher than those before training (P ＜ 0.05 or ＜ 0.01).Scores of all 7 items of clinical skill test were higher than those before training (P ＜ 0.01).The main factors influencing the effect of training were gender,educational background,score before training and type of practice (P ＜ 0.01 or ＜0.05).Conclusions The clinical competence of general practitioners can be improved after the training.The training contents should be optimized in consistent with conditions of community health and general practitioners in the future.
