ObjectiveTo compare the effects of povidone iodine handwashing with brush and brush-free handwashing on the hand skin condition of nurses in operation room. MethodA random sampling method was used to choose 150 nurses from the operation room of a grade-3 class-A hospital as our study subjects from June 2013 to December 2014. They were randomly divided into control group and study group according to the random number table with 75 in each. The control group used the traditional povidone iodine handwashing with brush, while the study group applied brush-free handwashing method. Then, we compared the hand skin condition and disinfection effect of these two kinds of handwashing methods. ResultsThe control group had dry skin in 34 nurses (45.3%), dry desquamation in 9 (12.0%), tight feeling in 51 (68.0%), and allergy in 5 (6.7%). The study group had dry skin in 19 nurses (25.3%), dry desquamation in 0 (0.0%), tension in 21 (28.0%), and allergy in 0 (0.0%). The differences between the two groups were statistically significant (P<0.05). ConclusionsThe brush-free handwashing method is able to achieve the requirements of surgical hand disinfection, and can protect the skin of nurses in operation room.
ObjectiveTo investigate the risk factors associated with failure of weaning from invasive mechanical ventilation in gerontal patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). MethodsA retrospective study was conducted on 76 patients aged 65 years and older with AECOPD who received invasive mechanical ventilation and met the weaning criteria from July 2012 to June 2014. The subjects who passed the spontaneously breathing trial (SBT) and did not need mechanical ventilation within 48 h were enrolled into a weaning success group. The subjects who did not pass the SBT or needed mechanical ventilation again within 48 h were enrolled into a weaning failure group. The risk factors associated with failure of weaning were studied by univariate and multivariate Logistic regression analysis. ResultsThere were 53 subjects in the weaning success group and 23 in the weaning failure group. The incidences of sepsis, multiple organ dysfunction syndrome (MODS), fungal infection, hypoproteinemia, duration for mechanical ventilation > 14 d, the prevalences of aeropleura, cardiac failure, diabetes, coronary heart disease and hepatic insufficiency were higher in the weaning failure group than those in the weaning success group (P < 0.05). Logistic analysis revealed that MODS (OR=8.070), duration for mechanical ventilation > 14 d (OR=17.760), cardiac failure (OR=4.597) and diabetes (OR=13.937) were risk factors of weaning failure (P < 0.05). ConclusionMODS, duration for mechanical ventilation > 14 d, cardiac failure and diabetes were associated with the failure of weaning from invasive mechanical ventilation in gerontal patients with AECOPD.
Abstract： Objective To observe the expression changes of microRNA 1 （miRNA-1） and microRNA 21（miRNA-21） after ischemic preconditioning （IPC）, ischemic postconditioning （IPO） and remote ischemic preconditioning （RIPC）in an ischemia-reperfusion rat heart model in vitro, as well as the expression of their target protein heat shock protein 70 （HSP70） and programmed cell death 4 （PDCD4）, and evaluate whether miRNA are involved in endogenous cardio-protective mechanism. Methods The Langendorff-perfused Sprague-Dawley rat hearts were randomly assigned into one of the four groups, control group （CON group, n=12）, ischemia preconditioning group （IPC group， n=12） , ischemia postconditioning group （IPO group， n=12） and remote ischemia preconditioning group （RIPC group，n=12）. Cardiac function was digitalized and analyzed. The expression of HSP70, PDCD4, B-cell lymphoma/leukemia-2 （Bcl-2） and Bax was detected by Western blotting. The expression of miRNA-1 and miRNA-21 was detected by real-time reverse transcriotion-polymerase chain reaction （RT-PCR）. Assessment of cardiac infarct size and myocardial apoptosis was determined using triphenyltetrazolium chloride （TTC） assay and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay （TUNEL） assay respectively. Results The expressions of miRNA-1 and miRNA-21 were up-regulated in IPC group, but the expression of miRNA-1 was down-regulated in RIPC group and IPO group （P＜0.05）. The expressionsof PDCD4, HSP70 and Bax were down-regulated in ‘conditioning’ groups compared with CON group （P＜0.05）. The expression of Bcl-2 was not statistically different among the four groups. The infarct size and the myocardial apoptosis in ‘conditioning’ hearts were significantly decreased compared with CON group （P＜0.05）. Conclusion The expressions of the miRNA-1 and miRNA-21 are different in IPC, RIPC and IPO groups, and their target proteins are not inversely correlated with the miRNAs in all the ‘conditioning’ groups.
【摘要】 目的 观察糖尿病合并胃癌围手术期患者应用胰岛素泵的治疗效果。 方法 2004年1月-2010年12月收治的胃癌合并2型糖尿病患者86例，将患者随机分为常规组（A组）46例和胰岛素泵组（B组）40例，比较两组患者在血糖控制、手术并发症方面的差异。 结果 B组与A组出院时，空腹血糖以及餐后血糖均能达标，但B组明显好于A组（Plt;0.05）；B组胃排空障碍发生率降低（Plt;0.05）。 结论 胰岛素泵能更好地控制血糖、减少手术并发症的发生。【Abstract】 Objective To observe the therapeutic effect of insulin pump on type 2 diabetes mellitus combined with gastric cancer during the perioperative period. Methods Between January 2004 and December 2010, 86 patients with type 2 diabetes mellitus combined with gastric cancer were randomly divided into control group (group A, 46 cases) and insulin pump group (group B, 40 cases). The differences in blood glucose level and infection rate of operation incisions were compared between the two groups. Results Both groups reached the aimed glucose level (fasting blood glucose and postprandial blood glucose) at the discharge from the hospital, which in group B were significantly better than those in group A （Plt;0.05）. The obstruction of gastric emptying in group B decreased significantly (Plt;0.05). Conclusion Insulin pump can control the blood glucose and reduce the surgical complications．
ObjectiveTo observe the effect of Budesonide formoterol inhalant on teenager patients with allergic rhinitis accompanied with asthma. MethodsForty-five teenager patients with allergic rhinitis accompanied with asthma treated between January 2012 and December 2013 were randomly divided into general treatment group, budesonide group and budesonide formoterol group, with 15 patients in each. Another 15 subjects undergoing physical examination were designated as the control group. Besides routine treatment, the budesonide group was also treated with budesonide inhalation at 100-200 μg twice a day, and the budesonide formoterol group was also treated with budesonide formoterol inhalation at 160 μg and 4.5 μg twice a day. The course of treatment lasted for four weeks. The patients were followed up for four weeks after the use of medicine halted. After treatment, exhaled nitric oxide (NO) examination were performed. ResultsThe amount of NO in the exhaled gas in all the three treatment groups were significantly different from the control group (P<0.05), and it was also significantly different between the Budesonide group and the budesonide formoterol group (P<0.05). ConclusionBudesonide formoterol inhalant has a good effect on teenager patients with allergic rhinitis accompanied with asthma in terms of improving exhaled NO.
