Objective To explore the role of graph-text-combined health education in dieting health education for patients with hematologic diseases. Methods About 56 patients with hematologic diseases hospitalized in February 2015 were assigned as the control group and another 57 patients with the same diseases during March to April 2015 as the experiment group. In the control group, routine dieting health education was done and in the latter the graph-text-combined health education was used for the dieting health education. The two groups were compared in view of recognition on dieting knowledge, dieting compliance and patient's satisfaction level. Result The recognition on dieting knowledge, dieting compliance and patient's satisfaction level were all higher those of that the control group (P<0.05). Conclusions The graph-text-combined health education can improve the recognition on dieting knowledge, dieting compliance and patient's satisfaction level when it is used in the health education for the patients with hematologic diseases. Therefore, it is worth clinically popularizing.

OBJECTIVE To discuss the cause of CABG infection and its controlling methodology. METHODS In order to conduct comparative analysis of 40 cases of CABG incision infection and 40 cases of CABG without infection,the "rank sum test" statistical models were applied. RESULTS According to the analysis of statistics,the hospitalized days and costs in sample group with infection were higher than that of control group,and the difference had statistical significance.Compared with the control group,the hospitalized days of sample group with infection averagely increased 43.03 days(2.85 times),and the total hospitalized costs of it averagely increased RMB 84 314.38 yuan(2.02 times). CONCLUSIONS Apart from patients themselves,there are also many possibilities which will cause the infection,which request the on-going works on surgery skills improvement,standardizing the process of aseptic technique,disinfection and isolation,utilizing antimicrobial agents rationally,reducing patients′ hospitalized days before surgery,as well as improving the pre-operative management etc.

OBJECTIVE Discuss the cooperative relationship between The Office of Nosocomial Infection Control("the Office") and the Center for Disease Control and Prevention("the Center") in hospital.METHODS The cooperative relationship between the Office of Nosocomial Infection Control and the Center were analyzed,the third degree A Class hospitals in Beijing area.RESULTS 25 hospitals had set up Centers.Among them,there are special stuff in charge of the report of the infection in 17 hospitals which had the Office with the function of the Center.So far,none of the Offices with the function of the Center can operate all the functions of the office.CONCLUSIONS The setup of the Center is to detect and control infectious disease on the basis of nosocomial infection control.

Objective To understand the development history and current situation of healthcare-associated infection(HAI)management in children’s hospitals in China during the past 30 years.Methods A retrospective survey was conducted in 20 children’s hospitals,the investigated contents included:basic situation of hospitals, HAI management organizations and professionals,the support of hospital leaders for the management of HAI, training on HAI knowledge,monitoring on HAI,and so on.Results Up to 2015,20 hospitals all set up independent HAI management departments and HAI management committees,46.15%(6/13)of hospitals with more than 1 000 beds were understaffed in HAI management.There were a total of 88 professionals in HAI management in 20 children’s hospitals in 2015,53.41% (n=47)of professionals had bachelor degree,34.09% (n=30)were with intermediate professional title,46.59%(n=41)were nursing staff.Up to 2015,incidences and missing report rates of HAI,antimicrobial usage rates,incidences of HAI in neonates all decreased compared with 2006.In 2015,20 (100.00%)hospitals all carried out monitoring on antimicrobial application,multidrug-resistant organisms,disin-fection and sterilization,and provided personnel protective equipment.In 2015,9(45.00%)hospitals used non-tou-ch faucets in all wards,19(95.00%)hospitals supplied hand-drying paper towel and alcohol-based hand rub in all wards.None of professionals in these hospitals participated in national-level training on HAI for ≥3 times in 1996, professionals in 11 hospitals (55.00%)participated in national-level training for ≥3 times in 2015.Conclusion In the past 30 years,the management of HAI in children’s hospitals in China has basically met the requirement,moni-toring on HAI gradually improved,but allocation of HAI professionals and personnel quality ability still need to be strengthened.

Objective To investigate the status and influencing factors of infusion-related adverse events in third-party cord blood stem cell infusion. Methods A total of 305 patients successfully underwent haploidentical stem cell transplantation combined with the third-party cord blood(CB) infusion,were recruited by convenience sampling from January 2013 to December 2015,in hematological department of a tertiary hospital in Suzhou. A self-developed questionnaire and adverse event assessment scale were used to investigate the influencing factors. Results The rate of infusion-related adverse events was 49.51%,81.82% were related to cardiovascular adverse events with the high-est rate of hypertension(76.14%). Logistic regression analysis showed that age(OR=1.030,95CI%:1.010-1.051),HLA matching between CB and receptor (OR=0.589,95%CI:0.413-0.838),thawed CB cell activity (OR=1.064,95%CI:1.015-1.115)were major influencing factors. Conclusion Nurses should pay attention to patients who are elderly,with low matching HLA and receive thawed CB product with high cell activities,and provide timely nursing care in advance.

Objective To explore the effects and influencing factors of traditional occupational health training on occupational health literacy (OHL) of employees in micro-, small- and medium-sized enterprises. Methods A total of 540 employees from 154 micro-, small- and medium-sized enterprises, who participated (347 employees) and not-participated (193 employees) in traditional occupational health training, and 171 community residents/students (not-participated in occupational health training) were selected as the research subjects using the convenient sampling method. The OHL level was investigated using Occupational Health Literacy Questionnaire of National Key Populations. Results The overall OHL level of employees was 43.3% (234/540). Among them, the overall OHL level of untrained and trained employees was 38.9% and 45.8%, respectively, and the overall OHL level of community residents/students was 43.3%. The results of multivariate logistic regression analysis showed that the higher the educational level, the higher the OHL level (all P<0.01). The OHL level of untrained and trained employees was higher than that of untrained community residents/students (all P<0.05). The interaction of education level and training status had no statistical difference on the OHL level of the research subjects (P>0.05). The results of factorial design analysis of variance showed that the overall OHL score rate of untrained employees and trained employees was higher than that of untrained community residents/students (all P<0.05). However, there was no significant difference in overall OHL score rate between untrained and trained employees (P>0.05). Conclusion The role of traditional occupational health training in improving the OHL level of employees in micro-, small- and medium-sized enterprises needs to be improved. The responsibility of enterprise occupational health training should be implemented, and multiple measures should be taken to enrich the ways and approaches of occupational health education for enterprise employees, to effectively improve the OHL of workers.

Objective Using Wisconsin Stone Quality of Life questionnaire (WISQOL) to compare standard percutaneous nephrolithotomy(PCNL) and tubeless PCNL.Methods From January 2017 to June 2017,patients who met the criteria (no urinary tract infection,stones between 1-3 cm,hydronephrosis larger than 3cm,renal cortex thickness ＞ 2 cm and without serious heart,lung,liver and kidney dysfunction and coagulation dysfunction) and underwent PCNL were prospectively enrolled and randomized into 2 groups,standard PCNL group and tubeless PCNL group.Diclofenac sodium suppositories were used to relieve pain in all patients with obvious pain.The quality of life of these patients were estimated and compared by using WISQOL.Safety and efficacy were also estimated.Result At the end of the study,a total of 50 patients were included in the analysis.There were 24 patients in the standard PCNL group and 26 patients in the tubeless PCNL group.There were 9 male patients in the standard PCNL group and 17 male patients in the tubeless PCNL group.There was no significant difference in gender between the two groups.The differences between the standard PCNL group and tubeless PCNL group in mean age (yrs.) [(53.21 ±13.35) vs.(51.1 ± 11.5),P =0.55],stone diameter (mm) [(18.46 ± 5.58) vs.(18.75 ± 5.39),P =0.85],stone-free rate (23/24 vs.24/26,P =0.60),mean hemoglobin decline (g/L) [(11.87 ± 9.20)vs.(10.43 ± 8.49),P =0.56] were not significant.Mean dosage of acesodyne(pcs) in tubeless PCNL group (4.07 ± 1.49) was significantly less than that in standard PCNL group (7.54 ± 2.23).There were no patient need transfusion or postoperative fever management.The influence of perioperative quality of life of patients treated with tubeless PCNL is significantly better than those treated with standard PCNL in 16 items which includ energy,sleep,work and family,physical symptoms,concerns related to intimacy and travel,and general emotional well-being.Conclusion Tubeless PCNL can improve patients' quality of life compared with standard PCNL.

General Biology is basic discipline in Environmental Science and Engineering, which lays a basis for the specialized courses in this major. As the course involves a wide range of knowledge, traditional "cramming education" cannot attract the interest of students. To meet the needs of talents against the backdrop of "double world-class project", our teaching team applied the "double-cycle teaching mode" of blended teaching in the first class along with ideological education, professional education, innovation and entrepreneurship education in the second class of this course. With this method, major headway has been made in this course. This study is expected to serve as a reference for reform in other relevant courses.
