OBJECTIVE:To observe the effect of Sanhuang decoction combined with compound amino acid liposome healing membrane on treatment stage Ⅲ pressure ulcer. METHODS:According to the random number table,ninety cases of stage Ⅲ pres-sure ulcer were divided into control group A,control group B,and experimental group with 30 cases in each group. On the basis of the basic processing for each group,control group A was treated by dressing change with Sanhuang decoction only,control group B by dressing change with compound amino acid liposome healing membrane only,and experimental group by dressing change with Sanhuang decoction combined with compound amino acid liposome healing membrane. The results of treatment were observed and the curative effects were compared among 3 groups after 21 days or pressure ulcer healing. Three groups were com-pared with chi-square test and each two groups were compared with chi-square segmentation method. RESULTS:There was no dif-ference on total curative effect in control group A(62.1%)and control group B(66.7%)(P>0.05),however,there was statistical significance on total curative effect in experimental group(93.3%)and control group A(P<0.05),also in experimental group and control group B(P<0.05). CONCLUSIONS:The effect of Sanhuang decoction combined with compound amino acid liposome healing membrane on treatment of stage Ⅲ pressure ulcer is better than the effect of dressing change with Sanhuang decoction only or compound amino acid liposome healing membrane only,and the healing time of wound is shortened. This research is deserved further study.

Objective To investigate the effectiveness and safety of transcatheter radiofrequency ablation guided by a three-dimensional mapping system (Ensite or Carto) for the treatment of complex cardiac arrhythmias. Methods A cohort of 123 consecutive hospitalized inpatients during the period from February 2006 to December 2008 were selected for this study. These patients suffered from various arrhythmias, including paroxysmal atrial fibrillation (n=58). Persistent or permanent atrial fibrillation (n=10), atrial flutter (n=13), atrial tachycardia (n=12) and ventricular tachycardia or frequent ventricular premature beats (n=30). Transcatheter radiofrequency ablation for arrhythmias was performed under the guidance of an EnSite3 000/NavX or Array mapping system in 80 cases, and under the guidance of a CARTO mapping system in the remaining 43 cases. Results Successful ablation of arrhythmias was obtained by single operation in 106 cases(86.18%). Including 59 cases with atrial fibriUation,11 cases with atrial flutter, 10 cases with atrial tachycardia, and 26 cases with ventricular tachycardia or premature ventricular beat. Ablation procedure was carried out and was successful in 10 cases with a successful rate of 94.31%, including 5 cases with atrial fibrillation. 1 case with recurred atrial flutter, 1 case with recurrent atrial tachycardia, and 3 cases with ventricular tachycardia or premature ventricular beat. After operation, complications occurred in 6 cases, including cardiac tamponade in 4 cases, distal embolism of the left anterior descending coronary artery in 1 case, and pulmonary embolism in 1 case. Conclusion Three-dimensional mapping system can clearly and stereoscopically display the cardiac structures. Therefore, this technique is of great value in guiding the transcatheter radiofrequency ablation for complex arrhythmias, in improving the success rate of ablation and in increasing the safety of the procedure.

Objective To investigate the clinical characteristics and prognostic factors after percutaneous coronary intervention of women with the first non-ST-segment elevation myoeardial infarction.Methods A total of 123 female patients with AMI,including 70 patients with NSTEMI and 53 patients with ST-segment elevation myocardial infarction (STEMI),who received PCI within 24 hours of onset were selected from June 2013 to June 2015.The clinical data were compared between patients with NSTEMI and with STEMI.Cox regression model was used to analyze the prognostic factors for the elderly patients with NSTEMI.Results The female patients with NSTEMI had more cases of patients with hypertension (48 vs.26),diabetes (38 vs.38) and hyperlipidemia (52 vs.29)than the female patients with STEMI.Significant differences in systolic blood pressure [(134.31±22.26)mmHg vs.(125.04 ± 19.63) mmHg],levels of white blood cell [(9.02 ± 3.75) 109/L vs.(11.37 ± 3.63) 109/L] and troponin Ⅰ [(8.63 ± 18.34) μg/L vs.(18.79 ± 27.76) μg/L] were observed in the above two groups (l P ＜ 0.05,respectively).The rates of revascularization,major adverse cardiovascular events in NSTEMI group were higher than those in STEMI group during 1 year after discharge (47.7％ vs.28.0％,62.9％ vs.35.8％) (P ＜ 0.05,respectively).Cox survival analysis showed that white blood cell (HR =1.241) and troponin-Ⅰ (HR =1.026) elevation were the risk prognostic factors after PCI for women with the first NSTEMI.Conclusion More hypertension,diabetes,hyperlipidemia and higher levels of systolic blood pressure,lower levels of white blood cell and troponin Ⅰ were observed in women with the first NSTEMI.The long-term prognosis of female patients with NSTEMI is poor.And elevated levels of white blood cell and troponin-Ⅰ were the risk prognostic factors after PCI for women with the first NSTEMI.

Objective:To describe the real experience of the elderly who has felt happy during the time they stayed at nursing homes, and discuss the meaning which is behind their experience during the COVID-19 pandemic, to provide scientific basis for improving their subjective well-being.Methods:Qualitative explanatory phenomenological analysis methods, and semi-structured in-depth interviews were used to interview 21 elderly people living in Guangzhou Songhe Nursing Home. Data analysis and subject extraction were carried out with reference to the Colaizzi 7-step analysis.Results:The real experience of subjective well-being of the elderly in nursing homes has six themes: be satisfied with the nursing home management service, be satisfied with harmonious interpersonal relationship, be satisfied with good health, be satisfied with family support, grateful and expectations for the social support system, be satisfied with and grateful for the epidemic prevention work during the COVID-19 epidemic.Conclusions:The elderly who live in a nursing home with perfect management and service, care for each other, are healthy, receive family and social support, are grateful, and understand family and social support will be more likely to feel happy. Improving the subjective well-being of the elderly in nursing homes requires the coordination and support of nursing homes, the elderly, families, society and other aspects.
