Objective To investigate the clinical value of blood urea nitrogen and albumin ratio (B/A) in prognosis assessment of severe patients with gynecological tumors and female breast cancer. Methods General clinical data were collected from the Medical Information Mart for Intensive Care (MIMIC) for gynecological tumors and female breast cancer patients admitted to intensive care unit (ICU). According to the 360 days prognosis,patients were divided into survival group (n=472) and death group (n=388),and the general situation of two groups was compared. Patients were divided into low B/A group (B/A<0.075,n=435) and high B/A group (B/A≥0.075,n=425) based on B/A levels. Kaplan-Meier method was used to plot the survival curve,and Cox risk scale model was established to compare the correlation between B/A and 360 days all-cause death risk. Results The B/A of patients in death group was significantly higher than that in survival group (P<0.05). There was a non-linear trend between B/A and 360 days all-cause death risk (x2=18.790,P<0.001). Survival analysis showed that patients with high B/A had significantly lower cumulative survival than patients with low B/A,both in the general population and in patients with gynecological tumors or female breast cancer (P<0.001). Cox regression analysis suggested that B/A≥0.075 was an independent risk factor for 360 days all-cause death in severe patients with gynecological tumors and female breast cancer (HR=1.529,95％CI:1.197-1.952,P=0.001). Conclusion High B/A at ICU admission is an independent risk factor for increased long-term mortality in severe patients with gynecological tumors and female breast cancer,and helps clinicians and caregivers identify high-risk patients early.

Objective To understand the cleaning quality of dental handpieces in Suzhou City, analyze the relevant factors that influencing cleaning effect.Methods A cross-sectional study was performed with the proportional system sampling method, questionnaires were adopted to investigate the cleaning location, cleaning method and process of dental handpieces, the ATP fluorescence detection method was conducted to detect cleaning quality.Results In 10 administrative regions of this city, a total of 72 medical institutions were selected, 25 were public medical oral diagnosis and treatment institutions, 47 were private clinics.Cleaning effect of automatic handpiece cleaning machine was better than traditional manual cleaning (unqualified rate :3.95% vs 11.96%, P<0.05), unqualified rate of handpieces cleaned by cleaning personnel without inadequate knowledge was higher than that by personnel with adequate knowledge(14.88% vs 3.57%, P<0.05).Qualified rate of cleaning: different cleaning locations ranged from 5.00% to 11.23%, cleaning equipment was inadequate and sufficient 11.89% and 7.29% respectively, cleaning personnel were not designated and designated 12.16% and 9.83% respectively, but the difference were not statistically significant (all P>0.05).The quality of cleaning of handpieces could be improved if waiting time of cleaning ≤30 minutes, enzymes were used during cleaning, and purified water was used at the end rinse(all P<0.05);whether there was drying process and used lubricant, difference were both not significant.Conclusion Using automatic handpiece cleaning machine, cleaning personnel with adequate knowledge, cleaning waiting time ≤30 minutes, enzyme use during the cleaning process, and purified water use at the end rinse can improve the quality of cleaning of dental handpieces.

Objective To explore the cleaning status and cleaning quality of dental handpieces in various types of medical institutions in Suzhou City.Methods On October 26-31, 2015, dental clinics in the whole city were sampled according to cross-sectional survey and proportional sampling method, the cleaning quality of dental handpieces in each clinic was detected by ATP bioluminescence assay.Results 72 medical institutions, 201 handpieces, 402 samples in 10 administrative regions of the city were sampled, 42 samples was unqualified, unqualified rate was 10.45％, unqualified rate of cleaning of dental handpiece surface was higher than waterline of dental handpiece(17.91％ vs 2.99％, P<0.05).Cleaning quality of dental handpieces in different grades of medical institutions was different(P<0.05), tertiary medical institutions were all ualified, medical institutions without grade was 14.45％.According to the classification based on name of different medical institutions, cleaning quality of handpieces was statistically significant(P<0.05), cleaning efficacy of dental handpieces in department of stomatology of public hospitals was best(unqualified rate was 4.31％), while private dental clinics had the worst cleaning efficacy(unqualified rate was 13.81％).Conclusion Education and training of dental handpieces cleaning in the whole city should be strengthened, especially the management of cleaning of dental handpieces in low grade and private dental clinics.

cleaning and disinfection.Results All 28 surveyed medical institutions had separate endoscope disinfection rooms, 89.29% of which had integrated endoscopic cleaning station,17.86% had automatic endoscope washer/disinfector;100% used multi-enzymatic detergent,chose the right disinfectant,monitored disinfectant concentration every day, and implemented standard disinfection time.But only 39.29% changed multi-enzymatic detergent for each endo-scope,cleaning and disinfection personnel in 78.57% of medical institutions wore personal protective equipment correctly.77 digestive endoscopes were detected,the qualified rate was 88.31%.Conclusion Cleaning and disin-fection management of digestive endoscope in secondary and above medical institutions in Suzhou City is generally standardized,there are still some problems in the manipulation procedures,relevant national regulations should be strictly complied with,efficacy of cleaning and disinfection of digestive endoscope should be further improved.

Objective To investigate the effects of club mode of health education on social support of breast cancer patients and their spouses.Methods A total of 100 breast cancer patients who underwent modified radical mastectomy and their spouses in Suzhou Municipal Hospital from May 2012 to March 2013 were randomly divided into the intervention group and the control group with 50 cases respectively. Patients and spouses in the intervention group were involved in the club, while in the control group patients and spouses received routine nursing care. Perceived social support scale (PSSS) and social support ratings scale (SSRS) were used in the questionnaires for patients before the intervention and at the 1st month, 3rd month, 6th month after the intervention.Results In the intervention group, the score of the support on the patients out of family was (29.80±5.77) at the 1st month after the intervention; the total score of perceived social support was (57.22±5.26) at the 3rd month after the intervention; the score of support from family was (26.59±2.51) at the 6th month after the intervention. All of those scores were significant higher than those in the control group (F=6.391, 0.304, 7.435;P<0.05). At the 3rd month after the intervention, the score of the social support on the spouses were (45.02±6.40) in the intervention group and (39.17±7.77) in the control group. The difference between the two groups was statistically significant (F=1.250,P<0.05).Conclusions The club mode of health education can effectively improve the social support status for breast cancer patients and their spouses.
