Chinese Journal of Practical Nursing 2011;27(22):1-3
Objective To discuss influence of evidence-based nursing on compliance and quality of life of patients with coronary heart disease after percutaneous coronary intervention (PCI). Methods From January to September, 2010, 86 patients with coronary heart disease undergoing percutaneous coronary intervention therapy were randomly divided into the study group and the control group with 43 patients in each group. Two groups of patients underwent percutaneous coronary intervention therapy and routine care after related check-up, and the study group was given comprehensive and systemic evidence-based nursing intervention on the basis of routine care. Medical compliance and life quality and other clinical indicators of the two groups of patients were comparatively analyzed. Results Compared with the control group, fully compliance rate of the study group was significantly higher, and partical compliance rate decreased significantly. At the same time, score of neurological function, psychological function, social function and other aspects of material life were significantly increased in the study group. Conclusions Application of evidence- based nursing has significant meaning for improving compliance and life quality of coronary heart disease patients undergoing percutaneous coronary intervention, which is worthy of further clinical promotion and application.

Objective:To compare suicide attempters with community-based controls for more specific prevention strategies.Method:From the list of suicide attempters of three general hospitals 2 years before, 363 of 786 attempters (48.5%) were found. We collected a control group matched for sex, age and location of residence and compared the life events for the past two years, life quality, family cohesion and adaptability of the past month, and impulsivity and aggressiveness.Result:The two groups were similar in sex, age, family income, marital status, occupation and health insurance status. But the suicide attempt group had less education, had more prominent impulsive and aggressive in traits, had higher levels of hopelessness, more negative life events and greater distress from negative life events in the two years after their attempt. They had poorer life quality and lower family cohesion and adaptability for the past month. They had also more severe depressive symptoms in the prior week.Conclusion:Two years after their suicide attempt, the attempters still have substantial differences from normal controls. They are a distinct high-risk subgroup that deserves specific interventions.

Objective To investigate the effect of antiserum against VEGF on angiogenesis and growth of bladder cancer in a mouse model in order to explore a novel strategy for the treatment of bladder cancer. Methods Antiserum against VEGF was prepared by using recombinant human VEGF and was identified for its specific affinity with VEGF by ELISA.The bladder carcinoma cell lines BST739 were implanted in T739 mice which were randomly divided into 2 groups:the control group receiving normal mice serum intraperitoneally,and the experimental group receiving antiserum against VEGF intraperitoneally.All the animals were sacrificed at last.Then all the bladder carcinomas were weighted and the microvessel density (MVD) in them was studied by immunohistochemical staining. Results The antiserum against VEGF was prepared and demonstrated with high specificity. The MVD in the antiserum group was lower than that in the control group. But the average weight of tumors was not significantly less in the antiserum group. Conclusions The study shows that to inhibit the activity of VEGF may reduce the angiogenesis in bladder cancer and supports the antiangiogenic therapy for bladder cancer.Inhibition of VEGF activity might become an important way of adjuvant therapy for bladder cancer.

Objective:Describe the prevalence of depressive disorder and the care-seeking of depressed individuals among inpatients in general hospitals in Beijing.Methods:2 925 inpatients ≥15 years of age from 40 general hospitals (selected by stratified random sampling) were first screened by psychiatric nurses and then psychiatrists used DSM-IV criteria to generate a 'gold standard' diagnosis in subjects screened positive and 10% of those screened negative. Results:Adjusted point prevalence, one-year prevalence, and lifetime prevalence of any type of depressive disorder were 7.04%, 7.47% and 9.96%, respectively; corresponding prevalences of Major Depressive Disorder were 3.83%, 4.33%, and 6.11%, respectively. Of the 123 depressed patients only 12 (9.8%) had ever received treatment. The prevalence was significantly higher in females than in males(5.18%vs 3.59%,RR=1.44 95%CI:1.01~2.05), in patients from Level-2 hospitals than in those from Level-3 hospitals(6.28%vs 3.31%,RR=1.90 95%CI:1.31~2.75), and in patients on internal medicine wards than in those from surgery (6.08%vs3.60%,RR=1.69 95%CI:1.15~2.49)or other wards(6.08%vs 3.01%,RR=2.02 95%CI:1.21~3.37).Conclusions:The prevalence of depressive disorder among inpatients in Beijing's general hospitals is high but very few are diagnosed or treated. Different programs to increase the recognition and treatment of depression in general hospitals need to be developed and regularly monitored.
