The issue as to whether hospital ownership has an impact on the quality of care has long been a serious concern.Hand hygiene (HH) compliance is regarded as an important indicator of the quality of care in the control of hospital-acquired infections.However,little information is available on whether hospital ownership influences HH compliance.In this study,of 229 hospitals selected from Hubei province in China,152 were public and 77 were private hospitals.A total of 23 652 healthcare workers (HCWs) were surveyed,using a convenience sampling.HH compliance,the WHO's "My Five Moments for hand hygiene" (5MHH),among HCWs,together with the factors of hospital ownership,training frequency,bed occupancy rates,etc.were collected.Univariate analysis and ordinal logistic regression analysis were used to analyze factors affecting HH compliance.Overall,HH compliance rates were 67％ and 79％ for public and private hospitals,respectively.The HH compliance rates of HCWs and 5MHH were between 55％ and 95％,and influenced by hospital ownership (P＜0.05),excluding compliance rate at the moment after body fluid exposure,and other influence factors included training frequency and bed occupancy rate (P＜0.05).HH compliance is better in private than in public hospitals.Hospital ownership is a significant factor affecting HH compliance,in addition to training frequency and bed occupancy rate.

Objective To learn the current status of job burnout and influencing factors for nurses from infectious disease hospital.Methods The Chinese version MBI -HSS was used to survey 218 nurses from infectious disease hospital,and linear regression was used to analyze the influencing facters of job burnout.Results A total of 210 questionairs were cocleted.The incidence of severe occupational job burnout was 22.38%,and the score of emotional exhaustion (EE), depersonalization (DP),personal accomplishment (PA)was(22.82 ±9.98),(6.48 ±5.20),and (35.20 ±8.82), respectively.Regression analysis demonstrated that the main influencing factors were entering the isolation ward, opportunity for infectious diseases ,disinfection damage,fear of occupational exposure and concern on family infection(P <0.05).Conclusion The status of job burnout of nurses in infectious disease hospital is not optimistic.There is a positive relationship with the working environment,occupational exposure.Managers need to explore an effective way to ease the job burnout of nurses,and to stabilize the nursing team.

Hypoxia-inducible factor-1 (HIF-1) is a key transcription factor on hypoxia responses in mammalian tissues. HIF-1 plays as a positive factor in solid tumor and leads to hypoxia-driven responses that enhance its downstream gene expression for tumor growth and survival. LXY6099 was obtained by the structural modification and optimization of manassantin A (MA) as a high potent HIF-1 inhibitor. Antitumor activity of LXY6099 was observed in this study. LXY6099 with an IC50 value of 2.46 x 10(-10) mol x L(-1) showed more sensitive inhibition activity to HIF-1 than that of MA detected by reporter gene assay (> 100 folds). It showed strong inhibition on the growth of human solid tumor cell lines. Furthermore, LXY6099 exhibited significant antitumor activity against established human tumor xenografts in nu/nu mice with treatment of MX-1 breast cancer. Thus, LXY6099 as a novel HIF-1 inhibitor could be further developed into anti-cancer agents.

Objective Insulin autoantibody (IAA) is known to exist in sera of type 1 diabetes mellitus (T1DM) patients and pre-T1DM individuals. The aim of this study was to establish a novel microtiter plate radioimmunoassay (RIA) for IAA and evaluate its clinical value. Methods Diluted 125Ⅰ-insulin was mixed with 5 ul serum samples in a 96-well microtiter plate and then incubated for 72 h on an orbital plate shaker (4℃). The immunocomplexes were transferred to another protein a coated Millipore plate, and then the plate was washed with Tri-Buffered Saline Tween-20 (TBT) buffer. Counts per minute (CPM) was measured with liquid scintillation and luminescence counter. The positive cut-off point of IAA index was defined as ≥0.06 based on the 99-percentile of the distribution in 317 healthy individuals. The specificity and sensitivity of the assay were calculated from the samples provided by the fourth Diabetes Autoantibodies Standardization Program (DASP 2005). The IAA levels were determined in 71 T1 DM and 551 newly diagnosed type 2 diabetes (T2DM) patients, and 317 healthy controls. The t test, non-parametric test, x2 test and linear correlation analysis were performed on the data using SPSS 11.5 software. The concordance rate was estimated with Kappa value. Results (1) The optimized testing condition was described as 2×104 CPM of 125Ⅰ-insulin, 5 ul serum sample and slowly horizontal shaking for 72 h. (2) The intra-assay CV was 4.8%-8.9% and inter-assay CV was 6.4%-10.5%. Based on DASP 2005 samples, the specificity and sensitivity of the assay were 97% (97/100) and 50% (25/50), respectively. Ninety-six serum samples with different IAA levels were selected and tested to compare between our new method and a domestic IAA RIA kit. The results showed that the IAA indices from the two methods were positively correlated (r= 0.678, P<0.001). The concordance rate was 72.9 %(Kappa value=0.402). There were 25 samples with discordant results, which were positive for IAA titer using the corresponding microtiter plate RIA but negative using the novel RIA kit. (3) In TIDM group the positive rate of IAA was 19.7% (16/71), higher than the healthy controls (0.9%, x2=54.36, P<0.001). The subgroup of T1DM children (with 0-9 years) showed the highest IAA positive rate (55.6% ,x2=4.85, P<0.05). In T2DM group the frequency of IAA was 1.5% (8/551), which had no significant difference comparing with that of healthy controls (x2= 0.95, P >0.05). Conclusions Our proposed microtiter plate RIA method for IAA is highly sensitive and specific, likely to be feasible for clinical application. The frequency of IAA is high in children with T1DM.

Objective To evaluate subclavicular angiography with brachial-axillary artery externally and temporally occluded in depicting hemoptysis-related ectopic arteries originating from shoulder, neck and chest wall in the interventional treatment of hemoptysis. Methods A retrospective analysis of the medical records and angiograms of 103 patients who underwent transarterial procedures for hemoptysis was carried out. The arteries originating from the subclavicular arteries supplying the shoulder, the neck and the chest wall, ectopic bronchial arteries (EBA) as well as non bronchial systemic arteries (NBSA), were depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. The number and distribution of the responsible aberrant arteries were investigated. Results Of the hemoptysis-related arteries(n=372) depicted and embolized in the studies, 51.9% was normally-originated bronchial arteries(n=193),6.7% was ectopic bronchial arteries (n=25),41.4% was NBSA(n=154).Both anomalous and NBSA arising from subclavicular-axillary area(n=80) were accounted for 21.5% (80/372) of all aberrant arteries, and 44.7%(80/179) of all anomalous and NBSA (n=25+154=179).Of those arising from subclavicular-axillary arteries,56.3%(45/80) were found to be originated from the internal thoracic artery (n=45),98.2%(112/114)of responsible internal thoracic arteries and their distal branches were well depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. Conclusion Subclavicular-axillary artery is a very important vessel where EBA and NBSA originate. Subclavicular angiography with brachial-axillary artery externally and temporally occluded could help to determine the abnormal arteries in the region quickly. The method should be taken as a routine procedure for interventional treatment of hemoptysis.
