ObjectiveTo investigate the effect of noninvasive positive-pressure ventilation for elderly patients with chronic obstructive pulmonary disease (COPD) combined with left heart failure. MethodsA total of 152 patients (70-85 years old) diagnosed with COPD combined with left heart failure and treated in our hospital between June 2011 and January 2015 were randomly divided into trial group (noninvasive positive-pressure ventilation with routine treatment, n=76) and control group (routine treatment, n=76). Respiratory rate, heart rate, blood pressure, pH, arterial partial pressure of carbon dioxide (PaCO2), arterial partial pressure of oxygen (PaO2) and left ventricular ejection fraction (LVEF) were analyzed and compared between the two groups after treatment. We did t-test to analyze the difference of these indexes between the two groups statistically. ResultsRespiratory rate, heart rate and PaCO2 in both of the two groups after the treatment were significantly lower than those before the treatment (P<0.001), while PaO2 and LVEF in both of the two groups after the treatment were significantly higher than those before the treatment (P<0.001). The systolic pressure and diastolic pressure in both of the two groups after the treatment didn't differ much from those before the treatment (P>0.05). The pH value after the treatment increased only in the trial group compared with that before the treatment (P<0.05). The respiratory rate, heart rate, pH value, PaO2, PaCO2 and LVEF after the treatment in trial group were meliorated compared with those in the control group (P<0.05). ConclusionTreatment with noninvasive positive-pressure ventilation for elderly patients with COPD combined with left heart failure is more efficient than the routine treatment.
ObjectiveTo explore the plan-do-check-action (PDCA) circulation method in reducing errors in general inspection items of health examination and to improve the quality of examination. MethodsUsing PDCA circulation method, the reasons of errors in general items of health examination for 39 individuals examinied between August and December 2010 were analyzed. Rectification was carried out according to the reasons, and the differences in the incidence rate of errors in general items of health examination before (from August to December, 2010) and after the rectification was (from Auguest to December, 2011) was compared. ResultsAfter the rectification, the incidence of errors in general items of health examination (0.08%) was significantly lower than that before the rectification (0.45%) (P<0.05). ConclusionPDCA circulation method can effectively reduce the incidence of errors in general items of health examination thus may ensure the medical quality.
Social Evaluation is an important reference to guide the reform and development of a public hospital. In view of the patient, hospital stakeholders and the public, West China Hospital of Sichuan University creatively constructed a social evaluation system, including patient satisfaction degree, expert appraisal and online public comment, in order to maintain a good medical environment. After several years of construction and application, the system has been quite effective in promote the development of the hospital. In the assessment of patients' satisfaction degree toward the hospital, we made a great improvement.
We investigated the baseline brain activity level in patients with major depressive disorder (MDD) by amplitude of low-frequency fluctuation (ALFF) based on resting-state functional MRI (fMRI). We examined 13 patients in the MDD group and 14 healthy volunteers in the control group by resting-state fMRI on GE Signa 3.0T. We calculated and compared the ALFF values of the two groups. In the MDD group, ALFF values in the right medial prefrontal were higher than those in control group, with statistically significant differences (P<0.001). ALFF values in the left parietal in the MDD group were lower than those in control group with statistically significant differences (P<0.001). This resting-state fMRI study suggested that the alteration brain activity in the right medial prefrontal and left parietal ALFF contributed to the understanding of the pathophysiological mechanism of MDD patients.
