ABSTRACT
Objective:To investigate the effects of 3D video thoracoscopic surgery combined with 3D CTBA (three-dimensional computed tomography bronchography and angiography) method in clinical education practice of the undergraduates.Methods:The study included in 60 undergraduate clinical interns from our hospital, and they were randomly divided into the experimental group ( n=30) and control group ( n=30). The teaching content was diagnosis and surgical treatment of lung cancer. The experimental group applied 3D video thoracoscopic surgery combined with 3D CTBA teaching method. The interns studied the anatomy of lung and diagnosis of lung cancer based on the 3DCTBA and visited the operation of lung cancer under 3D thoracoscopy, which enhanced their knowledge of anatomical structure of lung. The control group applied traditional thoracoscopic surgery for lung cancer. Upon termination of clinic practice, all interns were tested with theoretical and clinical knowledge of lung cancer. A questionnaire survey was conducted among them to access the teaching effect. SPSS 18.0 was used for t test and chi-square test. Results:The scores of theory test were not significantly different between two groups. The scores of anatomic and operational knowledge of lung in the experimental group were significantly higher compared with the control group ( P<0.05). Questionnaire result showed that new teaching method could promote the interest in learning, motivated the desire for thoracic surgery, and improved the comprehension of clinical knowledge. More students approved the new teaching method. Conclusion:The new method, 3D video thoracoscopic surgery combined with 3D CTBA, has beneficial effect on clinical interns, which contributes to inspire the motivation and interest of learning and deepen clinic knowledge, and is a promising teaching method worthy of further exploration and application.
ABSTRACT
A questionnaire was used to investigate the emergency training needs of novel coronavirus pneumonia of disease prevention and control institutions in provinces, deputy provincial level regions and cities specifically designated in the state plan, and the effect evaluation of emergency training activities conducted by Chinese Center for Disease Control and Prevention (China CDC). The results showed that 67.4% of 47 disease prevention and control institutions (31/46) believed that the emergency training at the initial stage of the epidemic should be conducted as soon as possible, and the form of network training should be given priority. The training should focus on the urgently needed technologies such as epidemiological investigation, formulation and response of prevention and control strategies, laboratory testing, etc. The teaching materials should highlight pertinence and practicability and be presented in the form of electronic video. The average satisfaction score of the video training conducted by China CDC was (8.81±1.125) and the score of audio-video courseware was (8.97±0.893). The needs analysis and evaluation of novel coronavirus pneumonia prevention and control in disease prevention and control institutions could provide reference for the follow-up training and improve the emergency training management.

Objective@#To evaluate the implementation effect of the Beijing Tobacco Control Regulation.@*Methods@#An observational study was conducted in a multi-stage randomly selected sample of 93 restaurants in Dongcheng and Chaoyang districts, Beijing. Undercover visits to the restaurants were paid by investigators at lunch or dinner time. The incidence of smoking behavior and the posters of no-smoking signs were observed, waiters were interviewed about awareness of the regulation, and comparisons with the baseline data of 6 months before and 1 month after regulation implementation were made.@*Results@#The pasting rate of no-smoking signs was 76.3%. The awareness of the regulation in the waiters surveyed was high. The incidence rate of smoking in restaurants (29.0%) was lower than that before the regulation implementation (36.7%), but it was significantly higher than that one month after regulation implementation (14.8%). No active interventions from the restaurant staff were observed when smoking occurred. The incidence of smoking in restaurants within commercial buildings (3.3%) was significantly lower than that in non-commercial buildings (41.3%), the difference was significant (P<0.05).@*Conclusions@#The effect of the regulation weakened 3 years after implementation compared with that in 1 month after the implementation. The enforcement degree of the regulation was conflicted with pasting rate of no-smoking signs and the regulation awareness level in waiters in restaurants in Dongcheng and Chaoyang districts.
ABSTRACT
Objective@#To analyze the risk factors for lung cancer and to provide scientific evidence for prevention of lung cancer.@*Methods@#A total of 461 newly diagnosed patients with primary lung cancer from January 2015 to June 2017 in Shaoxing were selected as the case group. Six hundred healthy residents with the same residence,distribution of gender and age as the cases were selected as the control group by frequency matching method. A questionnaire survey was conducted to collect demographic characteristics,family history of major chronic diseases,disease history and behavioral factors. The method of case-control study and multivariate logistic regression model were used for statistical analysis of the risk factors for lung cancer.@*Results@# The results of multivariate logistic regression analysis showed that after adjusting for age and gender,family history of cancer（OR=6.606,95%CI：3.439-12.689）,history of lung diseases（OR=2.836,95%CI：1.208-6.659）,high level of stress（OR=2.485,95%CI：1.830-3.376）,low consumption of fresh vegetables（OR=3.116,95%CI：2.470-3.930）and smoking（OR=6.029,95%CI：3.716-9.783）were risk factors for lung cancer;after adjusting for age,gender,family history of cancer,history of lung diseases,stress levels and consumption of fresh vegetables,quitting smoking for less than ten years was a risk factor for lung cancer（OR=4.751,95%CI：2.404-9.386）compared with quitting smoking for ten years or above.@*Conclusion@#Family history of cancer,history of lung diseases,high level of stress,low consumption of fresh vegetables and smoking were risk factors for lung cancer.
ABSTRACT
Objective To know the situation of extramarital sexual behaviors and HIV infection in middle-aged and elderly people in Chongqing,and provide reference for AIDS prevention and treatment.Methods From October to December 2017,a multi-stage sampling method was used to recruit middle-aged and elderly people aged ≥50 years who lived in Dazu and Hechuan districts of Chongqing for at least one year,with a sample size of 410.Face-to-face questionnaires survey and HIV antibody test were conducted.Results A total of 408 people were surveyed,including 313 males and 95 females aged 50-88 (64.93 ± 9.03) years.The HIV infection rate was 1.47％ (6/408),with the rate of 1.28％ (4/313) in males and 2.11％ (2/95) in females.The awareness rate of AIDS related knowledge was 37.50％ (153/408).And 18.87％ (77/408) of subjects surveyed reported extramarital sexual behaviors,7.60％ (31/408) reported extramarital sexual behaviors in the past half year,the constant condom use rate was 19.35％ (6/31).The results of multivariate logistics model analysis on extramarital sexual behaviors showed that the prevalence in males were 39.51 times higher than that in females (OR=39.51,95％CI:5.03-310.30),4.60 times higher in those who were unmarried,divorced or widowed than that in the married or cohabitants (OR=4.60,95％CI:1.50-14.05),2.03 times higher in those with outside activities than those with individual activities (OR=2.03,95％CI:1.08-3.81) and 3.94 times higher in those with self-evaluation of emptiness of living state than that in those with engaged life (OR=3.94,95％CI:1.86-8.36).Conclusions The prevalence of extramarital sexual behavior in middle-aged and elderly people in some counties and districts in Chongqing is high.The factors such as gender,marital status,leisure activities,and self-evaluation of living state were related to the prevalence of extramarital sexual behaviors in this population.The condom use rate in extramarital sexual behavior was low.It is necessary to take effective interventions in this population.

ABSTRACT
Objective To understand the current status,type,and effect of training programs conducted by Health Bureau and CDC in China.Methods One person of each province was selected from China field epidemiology training network and designated as contact person who was responsible for collecting information of field practical training lasting for at least 6 months for staff of public health emergency and infectious disease control in each province from October 2001 to October 2010.Questionnaire including basic condition,organization and management,training design,faculty condition,trainee condition and training outputs was designed and filled in by contact person.Results There were 35 training programs covering over 9 provinces in China.The first province and city FETP started in 2004,including Guangdong FETP,Zhejiang FETP,Hangzhou FETP,Ningbo FETP and Guizhou FETP.Thirty-five training programs had 355 mentors,22(6％)were CFETP graduates and 57 (16％)were local FETP graduates.All program funds were paid by local governments.The training programs included two parts,theoretical lectures and field practice,which occupying 10％-20％ and 80％-90％ of the whole training time,respectively.Among 6 evaluative items including emergency investigation,surveillance analysis,surveillance evaluation,planned investigation,investigation report and paper publication,most programs(50％-94％) had less than average one person per time.Conclusions Field epidemiology training program after several years of development in china achieves the certain scale.Some provincial programs are successful,but the effect and quality of training programs in different areas are uneven.We suggest optimizing of field epidemiology training resources and further expanding China field epidemiology training network.
ABSTRACT
Objective To evaluate the methods of standard patient (SP)combined with case-based learning (CBL ) in humanistic quality cultivation for interns in the department of thoracic surgery. Methods Medical interns in the department of thoracic surgery were divided randomly into experimental(n=30)and control group(n=30)respectively. In experimental group,SP combined with CBL was used while in control group traditional teaching was used. At the end of the study,teaching effect was assessed by the final examination and questionnaires and the data were processed by t test andX2 test. P0.05). Scores of history-taking,medical check-up,paper writing quality in the final examination in experimental group were significantly higher than those in control group(P<0.01). Satisfaction degrees of doctor-patient communication,responsibility and service attitude in experimental group were better than those of control group(X2=16.484,10.335,20.376,32.851,P<0.01). Conclusions SP combined with CBL teaching method can stimulate the students' interests in thoracic surgery practice,improve the doctor-patient relationship and strengthen the ability of human-istic concern. It is a better clinical thoracic practice teaching method and it is beneficial to cultivating medical students with humanistic concern.
ABSTRACT
Objective To summarize the experiences in clinical diagnosis and surgical treatment of chest cancers invading the superior vena cava (SVC). Method Retrospective study of 12 cases with chest cancers invading the SVC, SVC and innominate vein were reconstructed with prosthesis in 3 cases, the side wall of the SVC was excised and repaired in 9 cases. Results Complete resection was performed in 10cases,2 cases had incomplete resection. There was no death associated with operation in these patients. All patients were followed up for 1 - 7 years after operation,and 3 cases were lost to follow up,5 of remaining 9cases were dead because of relapse and metastasis, their median survival time was 8 months,other 4 cases lived, their median survival time was 42 months. Conclusions Patients with chest cancers invading the SVC should have surgical treatment of not only tumor resection but also the vessel reconstruction,the prognosis would be better than without surgical treatment. These patients have a high quality of life and live with long-term survival.
