Medical professionalism is an important part of competencies which physicians are acquired to own.Team of physician's competency model construction and education revolution project concluded the current situation and theoretical cognition of physician's professionalism of experts from medical education and administration organizations in China according to the results of the first round of Delphi.Meanwhile,suggestions for the further improvement of physician's professionalism were pro

Objective To compare the cardiac function parameters in gated SPECT determined by filtered back projection (FBP) and OSEM reconstruction methods. Methods One hundred and forty-four patients underwent 99Tcm-MIBI gated-SPECT imaging studies. The parameters LVEF, EDV and ESV, were derived using quantitative gated SPECT (QGS), four-dimensional model SPECT (4D-MSPECT) and emory cardiac toolbox (ECToolbox) softwares. Each image was reconstructed by FBP or OSEM. Bland-Altman analysis and paired t-test were applied to evaluate those parameters. Results Correlation coefficients for LVEF, EDV and ESV between FBP and OSEM methods were all more than 0.93 (all P<0.001). EDV calculated by FBP was lower than that by OSEM using QGS software, but became the opposite when using 4D-MSPECT and ECToolbox softwares. (QGS: (82.2±39.1) ml vs (83.5±40.8) ml, t=-2.53, P<0.05; 4D-MSPECT: (93.5±46.9) ml vs (88.8±45.2) ml, t=5.95, P<0.01; ECToolbox: (106.4±51.1) ml vs (100.8±49.0) ml, t=3.99, P<0.01). ESV calculated by FBP was higher than that by OSEM using 4D-MSPECT software (4D-MSPECT:(37.5±41.4) ml vs (34.8±37.6) ml, t=3.92, P<0.01). LVEF calculated by FBP was lower than that by OSEM using QGS software ((62.1±16.9)% vs (63.1±16.1)%, t=-3.14, P<0.05), but higher than that by OSEM using ECToolbox software ((74.1±18.8)% vs (71.3±17.1)%, t=5.28, P<0.01). Conclusion Generally, cardiac functional parameters based on FBP and OSEM construction methods correlated well, although they might have singnificantly different results.

Objective To discuss the pathological classification and lesion's inner imaging features of lung adenocarcinoma presented as pure ground-glass opacity.Methods CT imaging features of 156 pGGO lesions which confirmed by surgery and pathology were analyzed in retrospectively.There were 58 lesions of pre-invasive (including atypical adenomatous hyperplasia and adenocarcinoma in situ),32 lesions of minimally invasive adenocarcinoma and 66 lesions of invasive adenocarcinoma.CT features were analyzed including lesion density,vacuole sign,air bronchogram and abnormal vascular changes (vascular dilatation,distortion or rigid).Results There were statistical difference in lesions density and abnormal vascular changes in 3 different pathological types (P ＜ 0.05),with increase of lesions invasive,the incidence of uneven density and abnormal vascular changes increase,its mean the more invasive of the lesion,the lesion tent to be more uneven and higher incidence of the dilation,twist or rigid of the vascular happened;while the incidence of the air bronchogram will be higher when the lesions invasive degree increased,but there was statistical difference only between the pre-invasive and invasive groups (including minimally invasive adenocarcinoma and invasive adenocarcinoma) (x2 =4.868,P =0.027).Conclusions The uneven density and abnormal vascular changes had certain value in differential diagnosis of lung adenocarcinoma presented as pGGO.

Commercial production of bioethanol from lignocellulosic hydrolysates requires efficient fermenting strains. The abilities of the strain to converting all types of sugars in the hydrolysate to ethanol in high yield and to effectively tolerating/metabolizing inhibitors are necessary. Genome shuffling is a novel method for breeding, and it has been applied in pharmaceutical and food industry. This review summarized the technique of genome shuffling including principle, process, applications and its prospect for strains improvement in ethanol production from lignocellulosic hydrolysates.

Objective To analyze psychological stress level and features of recruits in training camp.Methods Psychological stress self-evaluation test (PSET) was applied to 1 600 recruits in training camp.Results ①There were 64 recruits(64/1600,4％) who had high level of psychological stress(T score ≥70).②The psychological stress symptoms of recruits in training camp mainly manifested as increased alertness (87.7％),sleep deprivation (57.6％),mental and physical fatigue (48.7％) and nervous irritability (45.2％).③Psychological stress levels of recruits with different ages and different levels of self-feeling in camp had significant differences(P＜0.05).Conclusion Recruits in training camp have partly excessive psychological stress responses,targeted emergency decompression trainings should be carried out in recruits.

Objective To study the efficacy and safety of oral calcium carbonate suspension and proton pump inhibitors (PPI) in symptoms relief of acid related diseases.Methods The multi-center,randomized and controlled study was carried out.A total of 400 acid-related diseases patients from 14 to 70 years old with at least one of moderate or severe symptoms such as acid regurgitation,epigastric pain,epigastric discomfort,upper abdominal burning or distension were equally divided into two groups and treated with oral calcium carbonate suspension or omeprazole enteric-coated tablets.The onset of symptoms relief of all patients of the first time after taking medicine was observed.The relief of clinical symptoms at the third day and seventh day after taking medicine was also observed.The adverse events were recorded.Analysis of variance was performed for statistical analysis.Results The onset of symptoms relief of oral calcium carbonate suspension group in acid regurgitation,epigastric pain,epigastric discomfort,upper abdominal burning or distension of the first time after taking medicine were significantly faster than those of PPI group (F=4.866,8.142,41.366,6.955,35.252; all P＜0.05).At the third day after taking medicine,the treatment efficiency of oral calcium carbonate suspension group and PPI group were 69.50％ and 72.50％,and at the seventh day the treatment efficiency of oral calcium carbonate suspension group and PPI group were 92.00％ and 96.50％.There was no significant difference in treatment efficiency and comprehensive efficacy between two groups at day three and seven after taking medicine (both P＞ 0.05).There were 14 cases of mild adverse events and two cases of moderate adverse events in oral calcium carbonate suspension group.There were 10 cases of mild adverse events in PPI group.There was no significant difference between two groups (P＞0.05).Conclusion Oral calcium carbonate suspension provides faster symptom relief than PPI and can effectively improve the symptoms of acid-related diseases.
