To explore the cognitions and behavior of cough etiquette of 556 residents in Longhua Community and self-compare the changes of cognitions and behavior before and after health education and training.The results showed that awareness rate of cough etiquette was low before training (senior group:25.4％,children:11.9％,young white-collar:36.1％,immigrants:14.3％,P ＜ 0.05) and increased significantly (senior group:97.2％,children:99.2％,young white-collar:100.0％,immigrants:98.6％,P ＜ 0.05).Except for no difference in compliance aspects of immigrants (P ＞ 0.05),the other three groups improved after training.And the difference was statistically significant before and after training (P＜0.05).

Objective To investigate the therapeutic effect of bundle treatments for critically ill patients with pulmonary tuberculosis and respiratory failure (RF).Methods A prospective study was conducted, including 56 patients with pulmonary tuberculosis and RF necessary for invasive mechanical ventilation admitted into Department of Critical Care Medicine of the Fourth People's Hospital of Nanning City from January 2013 to December 2014 as the observation group to be treated by bundle treatments. A series of treatments and cares were given to the critically ill patients, such as invasive mechanical ventilation, application of antibiotics by experience within the first hour, supportive treatment targeted to hemodynamics in early stage, correction of brain dysfunction, effective therapy for tuberculosis, establishment of enteral nutrition in early stage and prevention of ventilator-associated pneumonia (VAP), etc. All the above treatments were completed one by one in 6 hours to 12 hours. Meanwhile, 42 patients who hospitalized from January 2011 to December 2012 and treated with conventional targeted therapy were designed as the control group. The changes of vital signs, blood routine test, respiration, liver, kidney, etc organ functions, the improvement of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, expected mortality and sequential organ failure assessment (SOFA) score, the incidence of VAP, cure and improvement rate, mortality, duration of invasive mechanical ventilation, the length of stay in intensive care unit (ICU) were compared between the two groups after treatments.Results There were no statistically significant differences in the comparisons between the two groups before and after treatments in temperature, white blood cell count (WBC), blood glucose, total bilirubin (TBil), alanine transaminase (ALT), albumin (Alb) and cholesterol level (allP > 0.05), except the platelet (PLT) count in observation group was higher than that in control group before treatments. After treatments for 72 hours, in the two groups, the heart rate (HR), respiration rate (RR), APACHE Ⅱ score and expected mortality were lower than those before treatments, while the arterial partial pressure of oxygen (PaO2) and oxygenation index were higher than those before treatments. There were no statistically significant differences in pH value, PLT, arterial partial pressure of carbon dioxide (PaCO2) and SOFA score before and after treatments in the control group (allP > 0.05). In the observation group, after treatments, the pH value was increased compared with that before treatments, while PLT, PaCO2 and SOFA score were decreased compared with those before treatments (allP < 0.05). The degrees of improvement of PaCO2 and oxygenation index in the observation group were superior to those in the control group [PaCO2 (mmHg, 1 mmHg = 0.133 kPa): 43.32±9.10 vs. 56.10±9.39, oxygenation index (mmHg): 330.60±100.98 vs. 245.65±83.20, bothP < 0.05]. After bundle treatments, compared with control group, the incidence of VAP was decreased [16.07% (9/56) vs. 33.33% (14/42),P < 0.05], improvement and cure rate was increased [78.57% (44/56) vs. 59.52% (25/42),P < 0.05] and mortality was decreased significantly in observation group [10.71% (6/56) vs. 28.57% (12/42),P < 0.05]. The duration of invasive mechanical ventilation (days: 9.15±3.59 vs. 16.96±13.44) and the length of stay in ICU (days: 13.30±4.24 vs. 23.00±15.03) in the observation group were shorter than those in the control group, but no statistically significant differences were found (bothP > 0.05).Conclusion The bundle treatments can effectively reduce the incidence of VAP and elevate the improvement and cure rate in patients with pulmonary tuberculosis complicated with RF.

Objective To select antiplatelet regimen according to the results of CYP2C19 gene polymorphism,and then compare the major adverse cardiac events,bleeding events and the incidence of adverse reactions between two antiplatelet regimens. Methods Two hundred and seven patients who were diagnosed with acute coronary syndrome(ACS)and underwent elective PCI were tested for CYP2C19 genetic polymorphism,and 94 cases with CYP2C19 intermediate metabolism were randomly divided into high-dose clopidogrel group and ticagrelor group(47 cases each).High-dose clopidogrel group was given clopidogrel 150 mg once daily,and ticagrelor group ticagrelor 180 mg twice daily.Major adverse cardiac events,bleeding events and the incidence of adverse reactions were observed between two groups one month later. Results The average declined platelet aggregation rate was significantly different between the two groups[(6.27±5.65)% and(12.30±10.23)%,P<0.01];Adverse drug reactions ,the incidence of bleeding events and major adverse cardiac events of two groups were not significantly different. Conclusion Ticagrelor has stronger antiplatelet aggregation effects than high-dose clopidogrel.There is no difference in short-term clinical outcomes between the two groups.
