Objective To understand the current situation of pressure steam sterilization in medical institutions in Xi'an city,and provide reference for the monitoring and quality control of pressure steam sterilization.Methods Central sterile supply departments(CSSDs) in medical institutions in Xi'an in 2012-2014 were investigated.Physical,chemical,and biological monitoring methods were used to evaluate the pressure steam sterilizers.Results A total of 135 medical institutions in Xi' an were monitored,including 40 tertiary medical institutions and 95 secondary and below medical institutions.A total of 540 specimens were collected,454 were qualified,overall qualified rate was 84.07 ％.Qualified rate of monitoring result of pressure steam sterilization of tertiary medical institutions was higher than secondary and below medical institutions(93.13 ％ vs 80.26 ％,x2 =13.91,P＜0.01).Qualified rates of chemical PCD and biological test pack of tertiary as well as secondary and below medical institutions were 100％ and ＞90％ respectively.The qualified rate of recoded temperature in secondary and below medical institutions was 88.42 ％,but actually measured temperature was 38.95 ％,which was significantly lower than 72.50 ％ of tertiary medical institutions(x2 =12.68,P＜0.01).The rates of the measured temperature＞ 134℃ of pressure steam sterilizer in each year were all low,but measured temperature＜132℃ was about 50.00 ％,difference between actually measured temperature and recorded temperature was-4℃-1 ℃,difference between-2.5 ℃-0.5℃ accounted for 80.00％,the main unqualified temperature was 130℃-131 ℃,accounting for 82.61 ％.Conclusion Efficacy of pressure steam sterilization is different in different levels of medical institutions in Xi'an,physical monitoring measures are not standardized,the supervision of physical parameters in key sectors should be strengthened to ensure the sterilization quality of medical institutions and reduce the occurrence of iatrogenic infection.

Objective To understand environmental quality status of clean operating rooms in municipal hospitals of Xi’an,and provide reference for ensuring the clean quality of operating rooms.Methods On-site specimen collec-tion and detection were conducted to detect and analyze the cleanlinss of air in clean operating rooms in 15 hospital of Xi’an.Results A total of 51 operating rooms were monitored,secondary and tertiary hospitals had 24 and 27 operating rooms respectively;26 were grade-I and 25 were grade-Ⅲ operating rooms.The qualified rates of dust particle≥0.5μm/particle size in grade-I and grade-Ⅲ clean operating rooms were 76.92% and 80.00% respective-ly,≥5μm/ particle size were 73.08% and 88.00% respectively.The qualified rates of dust particle counts in grade-I and grade-Ⅲ clean operating rooms were 61 .54% and 80.00% respectively,difference was not significant(χ2=2.092,P >0.05 ).The qualified rate of dust particle counts in clean operating rooms in tertiary hospitals was significantly higher than secondary hospitals(85.19% vs 58.33%,χ2 =4.600,P <0.05 ).The qualified rates of airborne microbes in operating zone of secondary and tertiary hospitals were 87.50% and 92.59% respectively(P >0.05),in surrounding zone were 95.83% and 92.59% respectively (both P >0.05).Conclusion Dust particle and airborne microbes in some clean operating rooms in municipal hospitals of Xi’an are beyond the standard,supervi-sion and management should be strengthened.

Objective To investigate the current status of hand hygiene(HH) among health care workers(HCWs) in clinical laboratories in medical institutions in Xi'an City.Methods HH status of HCWs in clinical laboratories in medical institutions in Xi'an was performed random on-the-spot sampling and monitoring.Results A total of 240 HH specimens of HCWs in clinical laboratories in 80 medical institutions in Xi'an City were collected, 127 detected results were qualified, the total qualified rate was 52.92%.The qualified rates of medical institutions were as follows: municipal hospitals 62.67%,workers' hospitals 55.95%,private hospitals 40.74%;comprehensive medical institutions 67.68%,specialized medical institutions 42.55%;tertiary medical institutions 79.63%(n=43),secondary and below medical institutions 45.16%(n=84),there were significant differences in HH qualified rate among HCWs in different types of medical institutions(all P<0.01).Of different HH detection items, detection rates of Escherichia coli and Staphylococcus aureus were 0.83% and 8.33% respectively.There were significant differences in HH compliance rates among HCWs of all age groups(χ2=9.103,P<0.05), HCWs aged≥50 years had the highest qualified rate of HH(71.43%), followed by those aged<30 years (67.82%),HCWs in 40~ year age group had the lowest HH qualified rate (39.66%).Conclusion The qualified rate of HH of HCWs in clinical laboratory of medical institutions in Xi'an City is low, it is necessary to enhance the procaution awareness of HCWs in clinical laboratories, strengthen quality control of HH, strictly implement standard hand-washing procedures to reduce occurrence of HAI.

OBJECTIVETo investigate the major influence factors of child neglect among rural areas children aged 3-6 years in China.

METHODSAccording to multi-stage stratified cluster sampling, distribution characteristics and the level of economic development, we randomly sampled 10 provinces, 26 cities (8 capital cities, 16 prefecture-level cities and 2 municipalities) using lottery method. Depending on the different level of economic and cultural, we sampled one medium county from each city (municipalities sampled two counties), a total of 28 counties. All towns were divided into high, medium and low three levels in accordance with economic and cultural, each level sampled one town, each conty sampled three towns, a total of 84 towns were sampled. Each town sampled 40 children, including 20 boys and 20 girls (including each 10 children aged 3 to 6, half and half boys and girls). 4 096 rural children aged 3-6 years old were sampled and surveyed of China. Based on "the Neglect Norms for Children Aged 3 to 6 Years Old in Rural Areas of China" explored the risk factors of child neglect. SPSS 18. 0 for windows was employed for statistics analysis. Multifactorial analysis was conducted through multivariate Logistic Regression.

RESULTSThe total neglected rate of the rural children aged 3 to 6 was 53.7% (2,047/3,810), and the total neglected degree was 44.42±7.57. The multivariate logistic regression analysis showed that, neglected risk of the boys was higher than the girls (OR=1.30, 95% CI: 1.13-1.49), neglected risk of children were higher, when their mothers were migrant workers (OR=2.18, 95% CI: 1.59-3.00); the lower educational level of mothers, the higher neglected risk of children, the children in families that mothers only received primary education or was uneducated were most likely to be neglected (OR=2.92, 95% CI: 1.91-4.47), the second was the families that mothers received primary education (OR=1.86, 95% CI: 1.29-2.69); the lower the household income, the easier to be neglected the children, the easiest one was the household income less than 5000 RMB (OR=2.85, 95% CI: 2.14-3.79), the second was 5000-9,999 RMB (OR=1.76, 95% CI: 1.40-2.20); the relationship between children and mothers was distanced, neglect risk of children was higher (OR=3.88, 95% CI: 1.31-11.52); left behind children were easier to be neglected (OR=1.30, 95% CI: 1.09-1.54).

CONCLUSIONThe influence factors among children aged 3-6 years in the rural areas of China were boys, mother's occupation, maternal education level, the relationship between children and mothers, household income and left-behind children.

Objective To evaluate the quality of diet among rural residents in Hanzhong, Shaanxi province and to investigate the relative factors. Methods A cross-sectional survey on dietary status together with a semi-quantitative food frequency questionnaire were conducted among rural residents aged between 18 and 80 in Hanzhong of Shaanxi,in 2010. Quality of diet was evaluated by using DBI-07 scoring and evaluating system. Linear regression models were developed to identify factors related to under or over intakes. Results 2 241 rural residents were under study. 65%of the residents’daily intake of grains,oil and salt exceeded the RNI while animal food,diary food,eggs, vegetables and fruits were under,to some extent. The average values of DBI_LBS and DBI_HBS were 24.83 and 5.70. The proportions of moderate under-intake (25≤DBI_LBS≤36) and moderate over-intake(14≤DBI_HBS≤19)were 33.4%and 51.0%. Factors as family number,education level, fortune index,physical activity,higher labor intensity seemed to be protective for dietary under intake (P<0.05). Moderate fortune index,drinking alcohol(more than once a week),being male,age and smoking status(>15 cigarettes per day)were risk factors for over-intake of diet(P<0.05). Factors as larger family size and having had education above the levels senior school were significantly and negatively associated with the over-intake of diet (P<0.05). Conclusion The main diet problem among the rural residents was related to under-intaken but over-intake did exist to some extents. Our study results called for specific intervention in improving the quality of diet among the residents in Hanzhong.
