RESUMEN
Objective:To evaluate the effect of teacher simulate standardized patient (TSSP) consultation training in pediatric practical teaching.Methods:A total of 120 interns from the five-year clinical medicine major of Batch 2015 were randomly divided into experimental group and control group. In the experimental group, 60 interns were trained by TSSP for consultation after admission. After the training, the clinical parents of the children were consulted and the children were physically examined under the guidance of teachers. In the control group, 60 interns were trained according to the same requirements, but TSSP consultation training was not included. At the end of the practice, the performance, operation skills and medical record writing ability of the interns were compared, and the satisfaction of the experimental group was investigated. SPSS 25.0 software was used for t test and chi-square test. Results:The medical record writing results of the experimental group were (96.15±3.00) points, significantly higher than that of the control group [(81.02±3.29) points], and the differences were statistically significant ( t = 26.38; P < 0.001). In the mini-clinical evaluation exercise (Mini-CEX), the scores of medical history collection, communication skills, humanistic care and physical examination were significantly higher than those of the control group ( t= 15.41, 17.67, 15.39 respectively; all P < 0.001). The experimental group had high satisfaction with the teaching method of TSSP consultation training. Conclusion:TSSP consultation training improves the intern medical record writing ability, doctor-patient communication ability, clinical operation ability, stimulates the learning interest of interns, trains the trainee doctors humanistic consciousness, integrates into the ideological and political education, effectively ensures the quality of practical teaching of pediatrics, and obtains recognition from intern, which is worth promoting.
RESUMEN
Objective@#To evaluate the efficacy of lung cancer screening in urban areas of Henan province by low-dose computed tomography (LDCT) from 2013 to 2017.@*Methods@#A cluster sampling method was used to select the residents of 40-74 years old in Henan province to investigate the risk factors and conduct lung cancer risk assessment. Subjects with high risk of lung cancer received LDCT for screening.@*Results@#A total of 179 002 residents completed the lung cancer risk assessment, and 35 672 subjects were identified as high risk of lung cancer, with a high risk rate of 19.93%. A total of 13 383 subjects with high risk received LDCT, and the screening rate was 37.52%. There were 786 cases diagnosed as positive nodules, and the detection rate was 5.87%. Among them, 755 cases of solid/partial solid nodule were ≥5 mm, 23 cases of non-solid nodules were ≥8 mm, 8 cases were intratracheal nodules, and 115 cases were diagnosed as suspicious lung cancer. The detection rate in males was 6.74%, which was higher than 5.02% in females. The detection rate was positively related with age (P<0.05).@*Conclusions@#The application of LDCT is a useful screening method which can elevate the early detection rate of positive nodules and other related diseases in lungs. In the future, males and older populations should be paid more attention to improve screening efficacy.
RESUMEN
Objective@#To evaluate effect of screening of esophageal cancer though comparing difference of survival level between screening and non-screening patients in Linzhou city.@*Methods@#The records pathologically diagnosed as serious hyperplasia/carcinoma and esophageal cancer were drawn from database of first round screening in Linzhou city from 2005-2013 and were assigned to the screening group. The records of new esophageal cancer cases which diagnosed within 2 years before, screening from the same village aged from 40 to 69, were drawn from database of cancer registry in Linzhou city and were assigned to the non-screening group. Five or 10 year survival rate with 95%CI of patients with different malignant degree diseases in the screening group and the patients with esophageal cancer in the non-screening group was calculated respectively. The survival curves between the screening and non-screening group were compared by Log rank method.@*Results@#All 26 908 persons were examined in first round screening in Linzhou city from 2005 to 2013. There were 374 persons with serious hyperplasia/carcinoma in situ, 157 persons with esophageal cancer (141 intramucosal carcinomas/submucosal cancers, 16 invasive cancers). The 5 year survival rate of serious hyperplasia/carcinoma, intramucosal carcinoma/submucosal cancer and invasive cancer were 95.0% (95%CI: 91.7%-97.0%) , 72.0% (95%CI: 62.7%-79.3%) and 41.7% (95%CI: 17.4%-64.6%) separately. The 5 year survival rate of esophageal cancer in screening and non-screening group were 68.7% (95%CI:59.9%-75.9%) and 40.8% (95%CI: 36.4%-45.2%). The 10 year survival rate of esophageal cancer in screening and non-screening group were 58.0% (95% CI: 44.6%-69.3%) and 34.3% (95% CI:29.1%-39.5%). The 5 or 10 year survival rate of esophageal cancer in the screening group were higher than that in the non-screening group in whatever sex or age. The survival distribution of the screening group was better than non-screening group (χ2=38.88, P<0.001).@*Conclusion@#More precancerous lesions and early esophageal cancer can be detected and patients' survival level was improved through organized esophageal cancer screening, which provided support to evaluate value of organized screening.

Objective@#To investigate the incidence and survival of esophageal cancer with different histological types and to understand the incidence trend and burden of esophageal cancer in Linzhou during 2003-2012.@*Methods@#All incidence records of esophageal cancer and population reported were collected from Linzhou Cancer Registry during 2003-2012. Incidence rate was calculated using gender and histological types. Age standardized incidence rate was calculated according to world Segi's population and Chinese census data in 2000. Age standardized incidence rate by world population between 2003 and 2012 was analyzed with JoinPoint regression model and estimated annual percentage change (EAPC) was calculated. 5-year survival rate was calculated with Kaplan-Meier model.@*Results@#There were 8 229 esophageal cancer cases in Linzhou during 2003-2012. The average annual incidence rate was 80.08/100 000 (8 229/10 276 481). Among all esophageal cancer cases, 7 019 (85.3%) were diagnosed as esophageal squamous cell carcinoma (ESCC). In Linzhou, the age standardized incidence rate by Chinese standard population and by world standard population was 80.92/100 000 and 81.85/100 000 in 2003, 67.97/100 000 and 68.63/100 000 in 2012. JoinPoint regression model showed that EAPC was-12.9% (95%CI:-16.4%--9.1%) for other and unspecified histological type between 2003 and 2012. The EAPC was-5.5% (95%CI:-9.2%--1.6%) for esophageal cancer between 2007 and 2012,-5.4% (95%CI:-7.0%--3.9%) for esophageal cancer in female between 2006 and 2012,-4.9% (95%CI:-9.5%--0.1%) for ESCC between 2007 and 2012. The 5-year prevalence of esophageal cancer was 215.49 per 100 000 (2 337/1 084 493), and 5 489 died within 5 years after incidence. 5-year survival rate of esophageal cancer was 34.6% (95%CI: 33.5%-35.6%).@*Conclusion@#Esophageal cancer had a decreasing trend in Linzhou. The survival rate was increasing. But, esophageal cancer was still a major burden in Linzhou. The major histological type was ESCC. ESCC had a similar decreasing trend with esophageal cancer.
RESUMEN
Objective To understand the effect of improving compliance rate to multidrug-resistant organism (MDRO)prevention and control measures on reducing MDRO transmission in the intensive care unit (ICU ). Methods All patients in 5 ICUs of a hospital in March-June 2014 were chosen,March 1-April 30,2014 was base-line survey stage,May 1-June 30,2014 was intervention stage (comprehensive intervention measures were taken), the implementation of patients contact isolation measures,as well as awareness of MDRO-related knowledge among health care workers(HCWs)in 5 ICUs before and after intervention were compared respectively. Results HCWs' awareness rates of MDRO transmission modes,contact isolation measures,and informing of department transfer after intervention were all higher than before intervention(100.00% vs 67.22% ,98.89% vs 61.11% ,93.33% vs 45 .56% ,respectively);except single-room isolation,compliance rates to other prevention and control measures (including doctor's advice on isolation,bedside isolation,wearing isolation gowns,adding isolation logo)were all higher than before intervention(>70% vs <50% ,all P<0.01). Detection rate of MDROs after intervention was lower than before intervention (7.16% [90/1257]vs 9.65% [117/1212],χ2= 5.00,P= 0.03). Conclusion Com-prehensive intervention measures can improve HCWs'compliance to prevention and control measures on MDROs, and reduce the transmission of MDROs.
