With the development of society, people request the doctors higher and higher, which advances a new project for cultivating the doctors in new century. In order to provide the basis for confirming the medical talent cultivating target of new century, we have finished the research on the request to the doctors in new century, and the purpose is to make our medical colleges cultivate more medical talents to meet the need of the 21st century.

Objective To explore the clinical characteristics of mycoplasma pneumonia with pulmonary atelectasis and lavage interventional effect through fiberoptic bronchoscopy in children.Methods During Jun 2012 to Apr 2013,fifty-three children diagnosed of mycoplasma pneumonia with pulmonary atelectasis who received fiberoptic bronchoscopy were enrolled as the experimental group.Thirty-five children diagnosed of mycoplasma pneumonia without pulmonary atelectasis were chosen as control group.According to the lavage interventional time of fiberoptic bronchoscopy,we divided the patients in the experimental group into two groups,the early group and late group.Clinical data and laboratory finds were collected and analyzed.Results The duration of fever,hospital stay and C-reactive protein (CRP) of the experimental group were significantly higher than those of the control group (P ＜ 0.05).The location of pulmonary atelectasis in the experimental group were usually in the right middle lobe (18 cases,33.9％).Under fiberoptic bronchoscope,all patients had obviously bronchial mucosa congestive edema.Some of them had follicular hyperplasia (9 cases,17.0％),mucosal erosion (3 cases,5.7％),mucus plug formation (7 cases,13.2％) and poor ventilation of segmental bronchi (4 cases,7.5 ％).Neutrophils (43 cases,81.1％) increased and phagocytic cells (31 cases,58.5％) dereased obviously in bronchoalevolar lavage fluid.After treatment in the experimental group,52 children (98.1％) got complete recruitment of atelectasis.The average duration of fever and hospital stay of the early group were significantly shoter than those of late group (P ＜ 0.05).Conclusion Children diagnosed of mycoplasma pneumonia with pulmonary atelectasis had longer fever duration and higher CRP level.Bronchoscopic interventional therapy promoted the recovery of pulmonary atelectasis.Using bronchoscop early in shorten the duration of fever and hospitalization in children diagnosed of mycoplasm pneumonia with pulmonary atelectasis.

Objective To assess the feasibility and safety of transradial approach in Chinese elderly patients undergoing coronary intervention.Methods In this prospective study, 764 elderly patients with coronary artery disease received percutaneous coronary intervention via either a transradial approach (TRA group) or a transfemoral approach (TFA group). The procedural success rate, success rate of artery access, puncture time, fluoroscopy time, dose of contrast, local complications and post-procedural pulmonary embolism were recorded and compared between 2 groups. Results There was no significant difference of the procedural success rate between the TRA group and the TRF group (96.3% vs. 98.2%, P＞0.05); there were also no differences of success rate of cannulation, mean fluoroscopy time and mean dose of contrast between the 2 groups. The mean puncture time was longer in the TRA group than in the TFA group (3.8±2.1 min vs. 2.0±3.4 min, P＜0.05). However, there were fewer access site-related complications in the TRA group than in the TFA group. Postprocedural pulmonary embolism occurred in 2 patients in the TFA group but none in the TRA group. Conclusion Transradial coronary intervention was feasible and safe in most Chinese elderly patients when performed by experienced operators.

OBJECTIVETo analyze the clinical characteristics of protracted bacterial bronchitis (PBB) in children.

METHODThe clinical data of patients seen from October, 2010 to March, 2014 in Department of Respiratory Diseases of our hospital were retrospectively analyzed. Inclusion criteria were over 4 weeks cough, receiving fiberoptic bronchoscopy, positive bacterial culture and (or) the increased percentage of neutral granulocytes in bronchoalveolar lavage fluid (BALF).

RESULTTwenty eight patients were involved, 26 were male (93%) and two were female (7%). The median age of patients was 8.5 months. The median duration of cough was four weeks. The average length of hospital stay was (8.3 ± 3.9)days. The main clinical feature was wet cough in 28 cases, wet cough with wheezing was seen in 21 cases. The wet cough phase distribution was irregular in 21 cases. The crackles with wheeze (in 21 cases) was main signs of PBB. The percentage of CD3⁻ CD16⁺ 56⁺ cells increased in peripheral blood. The fiberoptic bronchoscopic manifestations of PBB were luminal mucosal edema. Eleven patients also had airway malacia. The neutrophil median in BALF was 0.2. The positive rate of bacterial culture of BALF was 36%. The main bacteria were Streptococcus pneumoniae (50%) and Haemophilus influenzae (30%). The main treatment for PBB patients included amoxycillin/clavulanate potassium and second-generation cephalosporins. The average duration of treatment was (17.3 ± 3.2)days, the prognosis was good.

CONCLUSIONPBB is common in male infants. Persistent wet cough with wheezing was the main characteristic of PBB. PBB is commonly accompanied by immune dysfunction and airway malacia, and the pathogens were Streptococcus pneumoniae and Haemophilus influenzae.

Objective To establish a reasonable evaluation system of the training effect of residents and professional master degree graduates in order to meet the needs of the construction of medical education system.Methods A questionnaire study had been conducted by stratified sampling to evaluate the abilities of the residents and medical professional degree graduates who had finished residency training in Beijing from 2015 to 2016.The trainees were evaluated by themselves,their colleagues and patients they had dealt with.Results The results showed that 95.29％ of the trainees and 99.00％ of their colleagues or patients thought that the overall abilities of the trainees were "excellent" or "better",and the evaluation results of all kinds of personnel above were consistent.Statistical analysis showed that some of the sub items of each ability index were evaluated better than the others,such as professional ethics,team cooperation ability and interpersonal communication ability,while some of the sub abilities need to be improved such as the information and management ability as well as teaching and research ability.The comparative analysis indicated that the postgraduates were superior to the residents in abilities of clinical diagnosis and treatment,information and management ability,and teaching and research ability.Conclusion The study showed that the training effect of residents and professional degree graduates had met the basic requirements,but the comprehensive quality and innovation ability needs to be promoted.The combination of degree education and resident training helps to cultivate the comprehensive ability of medical talents.
