Objective To identify nurses' practice of 5A's smoking cessation intervention in clinical settings of Beijing.Methods A cross-sectional survey was conducted among 248 nurses by convenient sampling.The questionnaire included the frequency of nurses' practice of 5A's intervention and its influencing factors,nurses' self evaluation of competency,and tobacco-related curricula in school of nursing.Results Most nurses implemented “advice” and “evaluated the patients' smoking history and current status” more frequently,but nurses' practice of other interventions was dissatisfactory.The belief that smokers could benefit from quitting was facilitating,however the barriers included no motivations to quit smoking,heavy work,and the belief that helping smokers to quit is not the priority in nursing routine.The nurses got insufficient knowledge about smoking cessation through school education and in-service training (12.8％).Conclusions There's a big gap between the implementation of nurses' smoking cessation intervention,accepted smoking cessation education,smoking cessation intervention competency and the urgent demands to help patients quit smoking.

Objective To investigate the effects of Wuling Powder on insulin resistance of C57BL/6J mice induced by high lipid diet, and discuss the mechanism. Methods C57BL/6J mice were randomly divided into six groups:normal group, model group, rosiglitazone group, Wuling Powder in low, middle, and high dose groups, 10 mice per group. Besides the normal group, other five groups were fed with high fat and sugar diet, with a purpose to establish insulin resistance model. Normal group and model group were given pure water. Rosiglitazone group received a gavage with rosiglitazone of 0.75 mg/kg. Wuling Power low, middle, and high groups received gavage with Wuling Power of 1.23, 3.69, 11.07 g/kg, respectively, the does volume was 0.2 mL/10 g, once a day. The weight and abdominal girth were detected every week. At the end of the sixth week, mice were given 12-hour fasting, and their eyeball were taken for blood. The body weight, length, and fat in abdomen and both kidneys were detected. Paraffin section was made with HE staining. FPG and FINS of each group were detected. ISI and IRI were calculated, and TC and TG were detected. Results Compared with the model group, Wuling Powder can significantly reduce the body weight and abdominal girth of mice (P<0.01, P<0.001), improve liver fatty degeneration, lower the FPG, FINS, TCH, TG, IRI, and increase the ISI in mice (P<0.05, P<0.01). Conclusions Wuling Powder has the effect of preventing insulin resistance of C57BL/6J mice induced by high lipid diet.

Objective To evaluate the effects of positive end-expiratory pressure (PEEP) targeting optimal oxygenation on local gas distribution and inflammation in dogs with acute respiratory distress syndrome (ARDS). Methods ARDS was induced by saline alveoli-lavage and oleic acid intravenous. The animals were mechanical ventilated 4 h at optimal PEEP titrated by oxygenation. Computed tomography (CT) scans were performed before and after induction of ARDS and at the end the study. NF-κB was measured by electrophoretic mobility shift assay (EMSA), IL-6 and IL-10 were assessed by ELISA.Myeloperoxidase (MPO) and malondialdehyde (MDA) were measured. Pathological changes were examined under optical microscope. Results (1) Compared to baseline, total lung volumes decreased and nonaerated areas increased significantly after the induction of ARDS in both groups (P ＜ 0.05 ). Compared with ARDS models, PEEP titrated to achieve optimal oxygenation resulted in greater lung recruitment but was accompanied with hyperinflation, hyperinflation occurred in non-dependent lung. Compared with oleic acidinjured ARDS, the changing of hyperinflated lung areas was increased markedly in saline lavage-injured ARDS (P＜0.05). (2) Compared with right lung ventral lower lobe, lung injury score was lower in right lung upper lobe. Histological injury in right lung dorsal lower lobe was severer than that in right lung upper lobe and right lung ventral lower lobe. NF-κB activation of right lung dorsal lower lobe was markedly higher than right lung upper lobe (P ＜ 0.05 ). MPO and MDA were much higher with right lung dorsal lower lobe than right lung upper lobe and right lung ventral lower lobe ( P ＜ 0.05 ). Compared with right lung upper lobe and right lung ventral lower lobe, IL-6 and IL-10 increased markedly in right lung dorsal lower lobe ( P ＜ 0.05 ). Conclusions Alveolar hyperinflation and aggravated lung injury in non-dependent region were occurred at PEEP targeting optimal oxygenation. Hyperinflation was more common in saline lavage-injured ARDS.

Objective To evaluate and demonstrate ultrasonographic characteristics of mandibular ameloblastoma with active proliferation. Methods Nineteen subjects with ameloblastomas in the mandibles were examined with ultrasonography. In addition to sizes,internal echoes,the research was focused on blood flow of the tumors and destruction of mandibles. Ultrasonographic appearances of the tumors were compared with histopathological findings. Sensitivity and specificity of Doppler flow signals and destruction of mandibles for prediction of active tumor proliferations were calculated. Results Fifteen cases (79%)showed no or minimal flow signals on color Doppler flow imaging(CDFI), whereas the remaining 4 lesions demonstrated abundant flow signals,in which 3 cases were confirmed histopathologically with active tumor proliferations. The sensitivity and specificity of the Doppler flow signals for prediction of active tumor proliferations were 100% and 94%, respectively. Fourteen cases (74%) showed the mandibular cortices were thin but continuous,among the remaining 5 lesions showed local cortices destruction,3 of them were confirmed histopathologically with active proliferations. The sensitivity and specificity of the destruction of cortical bone for prediction of active tumor proliferations were 100% and 88 %, respectively. Conclusions Ultrasonography can be used as a new effective supplementary diagnostic method for mandibular ameloblastomas. CDFI of tumor vascularity and destruction of cortical bone could be used to predict active tumor proliferations and invasiveness.
