ObjectiveTo analyze the quality of life (QOL) and psychological status among patients having undergone cardiac resynchronization therapy (CRT). MethodsA total of 42 patients underwent CRT in our hospital during January 2011 to January 2014. All the patients were studied by MOS SF-36 scale and symptom checklist-90 (SCL-90) on overall QOL and psychological QOL, respectively. Another 42 healthy people in matched control group were also tested. ResultsThe QOL of patients after CRT was significantly lower than that of healthy subjects (P<0.05). The psychological status score, which was obtained by the examination of SCL-90, was significantly higher in patients after CRT than in the healthy population (P<0.05). The length of the disease course and leveling exercise tolerance are the influence factors for the QOL and psychological status in patients undergoing CRT. Gender does not make any difference between the two groups. ConclusionThe QOL of patients having undergone CRT is significantly lower than that of healthy people, and the psychological status score is higher. Medical staff need to pay attention to the mental illness (such as depression, anxiety and panic) of patients after CRT, especially in patients with long course of disease, and patients who fail to improve exercise tolerance or who are mateless. Psychological interventions can further improve the QOL of patients.
Micro- and integrated biosensor provides a powerful means for cell electrophysiology research. The technology of electroplating platinum black on the electrode can uprate signal-to-noise ratio and sensitivity of the sensor. For quantifying analysis of the processing method of electroplating process, this paper proposes a grid search algorithm based on the Monte-Carlo model. The paper also puts forward the operational optimization strategy, which can rapidly implement the process of large-scale nanoparticles with different particle size of dispersion (20-200 nm) attaching to the electrode and shortening a simulation time from average 20 hours to 0.5 hour when the test number is 10 and electrode radius is 100 μm. When the nanoparticle was in a single layer or multiple layers, the treatment uniformity and attachment rate was analyzed by using the grid search algorithm with different sizes and shapes of electrode. Simulation results showed that under ideal conditions, when the electrode radius is less than 100 μm, with the electrode size increasing, it has an obvious effect for the effective attachment and the homogeneity of nanoparticle, which is advantageous to the quantitative evaluation of electrode array's repeatability. Under the condition of the same electrode area, the best attachment is on the circular electrode compared to the attachments on the square and rectangular ones.
ObjectiveFor better health interventions, blood pressure control and reducing risk of cardiovascular events, we explored the effects of health education by nurses on hypertension patients after discharging. MethodsHypertensive discharging-patients from the department of cardiology of the West China Hospital of Sichuan University were enrolled from January to October in 2011. They were divided into two groups, including a health education group and a control group. The patients in the health education group were given all-side care, health guidance, education lectures and telephone follow-up by nurses. The control group got no intervention. After one year follow-up, the information about situation of blood pressure control, new-onset cardiovascular events and changes of life habits were collected from the two groups. SPSS 19.0 was used to perform statistic analysis. ResultsA total of 300 discharged hypertensive cases were included, with 150 cases in each group. The systolic blood pressure of patients in the health education group was significantly lower than that of the control group (P < 0.05). Both blood control rates and the habit of low salt intake in the health education group were also better than those of the control group (both P < 0.05). There was no significant difference in changes of smoking, drinking, physical exercise and new-onset cardiovascular events between the two groups. ConclusionHealth education by nurses could effectively improve the management of blood pressure in patients with hypertension.
