Objective To investigate the epidemiological characteristics of three common susceptive gene retared hearing loss in the patients with the congenital deafness in Liuzhou.Methods 161 patients with congenital hearing loss were diagnosed with audiologic evolutions,including newborns and outpatients.The blood samples of all patients were taken for the extraction of DNA which was amplified by PCR.The common mutationsl hot spots of the mitochondrial DNA 12SrRNA,GJB2 and SLC26A4 were examined by restricted enzyme and directed sequencing.Results 1 case(0.62%)was found to carry mitoehondrial DNA 12SrRNA A1555G and 4 patients(2.48%)carried heterozygotes or homozygotes pathologic mutations of GJB2.10 patients(6.21%)were heterozygous carriers with pathologic mutations,IVS7-2 A>G,in the SLC26A4 gene.The detection rate of GJB2,mitochondrial DNA A1555G and SLC26A4 mutations in 161 patients were 9.31%.Conclusion The patients with congenital hearing loss distributed different minority groups in liuzhou zone.The mutational frequencies of the three common gene related hearing loss in the patients of Liuzhou were noticeably lower than the data reported in other regions in China.The gene screening for deafness was very important for early diagnosis and treatment.

Objective:To survey the training requirements for doctoral candidates in general practice.Methods:A questionnaire survey was conducted to investigate the requirements for general practice doctorate training; the items included the training target, training objectives and training contents. A total of 130 stakeholders of general practice participated in the survey, including administrators in health committees, general practice educators of medical schools, general practitioners in hospital and community health service centers and students in general medicine. The participants were divided into training unit group ( n=42), employer group ( n=42) and doctor and student group ( n=46). Results:Among all training objectives, the training "general medicine scientific research ability" ranked the first (121, 93.1%); while 114 (87.7%) respondents believed that the training target should be the leading talents in general medicine. Regarding the content of clinical competence training, 86 (66.1%) respondents believed that there was a lack of medical care training for whole life-cycle and whole population currently. The training requirement for acute disease management and referral competence in employer group was significantly higher than the training unit group (χ2=25.73, P<0.01) and the doctor and student group (χ2=24.37, P<0.01). Most survey respondents believed that the doctorate candidates in general medicine should focus on scientific research training in community clinical medicine ( n=110, 84.6%), community preventive medicine and epidemiology ( n=114, 87.7%); 117 (90.0%) respondents believed that clinical research design and methodology training should be strengthened, and 125 (96.2%) respondents believed that clinical teaching thinking training should be strengthened; 108 (83.1%) survey respondents believed that it is necessary for their units to recruit personnel with doctoral degree in general medicine. Conclusion:The training of doctorate candidates in general medicine should aim at cultivating leading talents in general medicine, strengthen the training of clinical scientific research capabilities, and focus on cultivating their comprehensive abilities of "being able to research, be good at teaching, and understand management", so that they can truly become the leaders in this discipline.

German family physicians practice independently in clinics, and provide primary health care services. General practitioners are a type of specialists. The basis for the self-management of German doctors is the homogeneous medical education in Germany. The new round of medical education reform emphasizes the theory and practical training throughout the entire process of medical education. All medical students in Germany need to go to the clinic for internship and be familiar with primary health care models. Post-graduation education sets rotation plans and assessment standards according to the characteristics of general practice specialties, emphasizes the clinical practice time in the clinics, and urges doctors to continue medical education through the payment of medical insurance. This article draws on the German general practitioner training model, proposes to strengthen the enlightenment of general practice education during the education of undergraduate medical colleges, and strengthen the clinical practice of general practitioners and the construction of general practice training bases, as well as improve the ability of the community physician faculties, in order to provide a reference for the training of general practitioners in China.

Objective:To explore the criteria of general practice doctoral supervisors.Methods:The expert consultation questionnaire was formed by literature analysis. Experts in the field of general medicine from universities and tertiary hospitals in Shanghai were invited to participate in two rounds of Delphi consultation. The consultation content included the basic requirements and the importance evaluation of the selection criteria for general practice doctoral supervisors. Descriptive analysis and Analytic Hierarchy Process (AHP) were used to analyze the results of the study.Results:A total of 29 experts participated in the consultation, all with senior professional titles and doctoral degrees. The positive coefficient and expert authority coefficient of the two rounds of expert consultation were 1.0 and 0.925, respectively. The Kendall coordination coefficient of indicator importance evaluation were 0.436 and 0.397, respectively. The ethics, age, professional title, educational background and academic degree and diploma were considered to be included in the basic qualifications. The optimal standards for supervisor selection included teaching ability, scientific research ability, student training and team promotion ability that subdivided into 13 evaluation indexes.Conclusion:The basic qualifications and optimal standards for general practice doctoral supervisors have been preliminarily developed, which provides reference for selection of qualified general practice doctoral supervisors.
