ObjectiveTo investigate the value of ultrasound in diagnosis and differential diagnosis of uterine arteriovenous fistula (UAF).MethodsUltrasound results of 12 patients with UAF were analyzed retrospectively,and were compared with uterine artery angiography.ResultsUAF showed uneven echo signals of uterine muscle wall near endometrium or cesarean section incision and irregular echo-free zone on ultrasonographies,the typical case of which displayed “honeycomblike” change.Color Doppler ultrasound showed rich blood flow in local area and lake-like or multicolored mosaic change.Spectral Doppler waveform shape was characterized as high-speed low resistance.The ultrasonographic results of UAF were consistent with those of uterine artery angiography.ConclusionUltrasonography combined with uterine artery angiography contributes to the diagnosis of UAF.

OBJECTIVE To know the compliance and it′s impact factors of hand hygiene of healthcare workers.METHODS The wards and healthcare workers were sampled randomly.Survey the compliance,qualified rate and impact factors of hand hygiene of healthcare workers when they didn′t know to be observed by special training staffs.RESULTS The compliance and the qualified rate of hand hygiene was 30.2% bothly,and be affected by the time before or after operation,occupations and work post.The factors causing low qualified rate were anenough time and improper technique for washing hand,and drying hand wrong.CONCLUSIONS The hand hygiene for healthcare workers in hospitals should be strengthened.

Objective To evaluate the preliminary screening effect of the ESS、SAQLI and QOLOSAHS for OSAHS,and find out the most effective preliminary screening method.Methods The scores of ESS、SAQLI、QOL-OSAHS of the 93 participants were analyzed.The predictive values of the three scales for OSAHS were determined by receiver operator curve and discriminatory analysis.Results The sensitivity and specificity of ESS(ESS≥9 points) were 0.486 and 0.870.The sensitivity and specificity of SAQLI (≤246 points) were 0.914 and 0.522.The sensitivity and specificity of QOL-OSAHS (≤161 points) were 0.886 and 0.522.Conclusions ESS、SAQLI、QOL-OSAHS have moderate predictive value for OSAHS.SAQLI is better to drinker than ESS for diagnosis of OSAHS.

OBJECTIVE To analyze the effect of the disposable over-shoes for the control of nosocomial infection of the intensive care units(ICU). METHODS The effects of the disposable over-shoes for the environment contamination and nosocomial infection control of the surgical ICU were investigated. RESULTS The mean of air bacteria colony counts when disposable over-shoes were worn was lower than that when without their use by healthcare workers (P0.05). The rates of nosocomial infection beteen them were 21.5‰ and 17.1‰,respectively. CONCLUSIONS The use of disposable over-shoes can't improve the environment quality and is not benefit for the control of nosocomial infection of surgical ICU.

Diffuse large B-cell lymphoma (DLBCL) is a group of heterogeneous diseases, and further classification is of great value for prognostic stratification. In recent years, some subtypes with poor prognosis have been recognized, such as "double-hit" lymphoma or "double-expressing" lymphoma. In addition, the new molecular classification provides a new perspective for the accurate diagnosis and prognosis stratification of DLBCL. The mutation and deletion of p53 gene are high risk factors in the traditional sense of DLBCL, while with the application of the next generation sequencing and other technologies, the influence of more accurate gene mutation or deletion on prognosis and its prognostic value in new cell molecular subtypes still need to be further confirmed. This paper reviews the progress of cell phenotypes and molecular subtypes as well as p53 gene abnormalities in the prognosis of DLBCL.

Objective To evaluate the comprehensive medical goal appraisal system on hand hygiene compliance rate of health care workers(HCWs).Methods Comprehensive medical goal appraisal system was adopted to inter-vene hand hygiene compliance rate of HCWs in a comprehensive hospital ,hand hygiene compliance rates of HCWs and consumption of instant hand sanitizer per bed-day before (December 2012)and after intervention (January 2013-June 2014)were compared.Results Hand hygiene compliance rate after intervention was higher than before interven-tion (85.17% [18 208/21 379]vs 39.92%[853/2 137]),hand hygiene compliance rate enhanced by 113.35%(χ2 =2 590. 81,P <0.001).Hand hygiene compliance rates of HCWs of different departments,different occupations and different hand hygiene moments were all higher than before intervention (all P <0.001);after intervention ,hand hygiene compliance rate revealed a increased tendency,and has maintained high since October 2013 (>90%),consumption of instant hand sanitizer before and after intervention was 7.24 mL/bed-day(4 200 L/579 841 bed-day)and 10.54 mL/bed-day(9 323.5L/884 489 bed-day)respectively,the consumption after intervention increased by 45.58% compared with that before intervention. Conclusion Comprehensive medical goal appraisal can effectively enhance hand hygiene compliance rate ,and maintains at a high level;the measure can affect hand hygiene behavior of HCWs by hawthorne effect,and is an effective and long-term measure to improve hand hygiene compliance of HCWs.

ObjectiveTo evaluate the effect of respiratory failure "disease-characteristics nursing quality improvement" program(DNQIP)in respiratory intensive care unit(RICU).Methods On basis of patient-centered,evidence-based practice and high-quality nursing service chain,DNQIP nursing service procedure and scheme was built for patients with respiratory failure. The self-rating ability of nurses and the patients′ relevant indicators before and after the implementation of DNQIP were observed and evaluated.ResultsAfter DNQIP,the self-rating comprehensive professional ability of nurses was improved from(61.1±13.6)to(84.2±10.3)(P<0.05). The integrity of nurse′s assessment for patients with respiratory failure increased from 51.7% to 75.4%. The incidence of VAP decreased from 5.86‰ to 2.09‰.Conclusions Evidence-based DNQIP can improve the nursing quality provided to patients with respiratory failure and the ability of nurses.

PURPOSE: Vascular endothelial growth factor (VEGF) signal transduction mainly depends on its binding to VEGF receptor 2 (VEGFR-2). VEGF downstream signaling proteins mediate several of its effects in cancer progression, including those on tumor growth, metastasis, and blood vessel formation. The activation of VEGFR-2 signaling is a hallmark of and is considered a therapeutic target for breast cancer. Here, we report a study of the regulation of the VEGFR-2 signaling pathway by a small molecule, isomangiferin. METHODS: A human breast cancer xenograft mouse model was used to investigate the efficacy of isomangiferin in vivo. The inhibitory effect of isomangiferin on breast cancer cells and the underlying mechanism were examined in vitro. RESULTS: Isomangiferin suppressed tumor growth in xenografts. In vitro, isomangiferin treatment inhibited cancer cell proliferation, migration, invasion, and adhesion. The effect of isomangiferin on breast cancer growth was well coordinated with its suppression of angiogenesis. A rat aortic ring assay revealed that isomangiferin significantly inhibited blood vessel formation during VEGF-induced microvessel sprouting. Furthermore, isomangiferin treatment inhibited VEGF-induced proliferation of human umbilical vein endothelial cells and the formation of capillary-like structures. Mechanistically, isomangiferin induced caspase-dependent apoptosis of breast cancer cells. Furthermore, VEGF-induced activation of the VEGFR-2 kinase pathway was down-regulated by isomangiferin. CONCLUSION: Our findings demonstrate that isomangiferin exerts anti-breast cancer effects via the functional inhibition of VEGFR-2. Pharmaceutically targeting VEGFR-2 by isomangiferin could be an effective therapeutic strategy for breast cancer.
