Abstract: Objective To evaluate the biological characteristics of decellularized bovine jugular vein valved conduit treated with dyemediated photo oxidation. Methods From July 2009 to July 2010, this study was carried out in Xijing Hospital affiliated to the Fourth Military Medical University. Forty bovine jugular vein valved conduits were obtained from Qinchuan scalpers aged between 2 to 6 years with the weight ranged from 200 to 400 kg. Then, the 40 conduits were divided into four groups by random digital table with 10 in each group. The conduits were treated with glutaraldehyde in the glutaraldehyde group (GA group), were decellularized in the decellularized group (DC group), were decellularized and treated with dyemediated photo oxidation in the decellularized and dyemediated photo oxidation treated group (DP group) , and were not dealt with in the control group (CO group). Thickness, appearance, histology, water content, shrinkage temperature, breaking strength, and soluble protein level of the conduit wall and valve were detected and compared among the four groups. Results Thickness and water content of the conduit wall and valve in the DP group were similar to those in the CO group (Pgt;0.05), while thickness of both wall and valve in the DP group was less than those in the GA group (wall: 0.8±0.1 mm vs. 1.1±0.1 mm; valve: 02±0.1 mm vs. 0.3±0.1 mm, Plt;0.05), and water content of the conduit wall and valve in the DP group was more than those in the GA group (wall: 86.1%±2.2% vs. 70.4%±2.8%; valve: 87.1%±2.5% vs. 72.1%±3.1%, Plt;0.05). The breaking strength and shrinkage temperature of the DP group were similar to those of the GA group (Pgt;0.05), while the shrinkage temperature (wall: 84.7±1.4 ℃ vs. 70.4±0.3 ℃; valve: 85.7±1.5 ℃ vs. 70.7±0.6 ℃, Plt;0.05) and the breaking strength (wall: 10.4±1.1 N vs. 6.8±1.0 N; valve: 8.0±0.9 N vs. 3.2±0.6 N, Plt;0.05) of the DP group were higher than those in the CO group. Conclusion Decellularized bovine jugular vein valved conduits treated with dyemediated photo oxidation have nice biological characteristics.Key words: Dyemediated photo oxidation; Decellularized; Bovine jugular vein valved conduit; Biological characteristics
Abstract: Objective To evaluate the results of surgical treatment of tetralogy of Fallot in adults． Methods From July 2002 to August 2009，75 adult patients with tetralogy of Fallot received surgical treatment in Xijing Hospital, ForthMilitary Medical University．There were 35 males and 40 females, with age at l7 to 37 years (23.30±3.50 years), and eoperativehemoglobin at 143 to 231 g/L(172.00±31.00 g/L)．All these patients were diagnosed by.echocardiograph before operation. All the patients were received tetralogy of Fallot of corrective operation in the hypothermia cardiopulmonary bypass. A total of 46 patients had a transannular right ventricular outflow tract patch，and 29 patients had a non ansannular patch． Results Operation time was 157 to 276 min(221.32±41.34 min), cardiopulmonary bypass time was 68 to 163 min(91.71±28.35 min) and aorta intercepted time was 37 to 96 min（55.47±23.61 min）. There were 6 operative deaths with an operative mortality at 8.00％. The causes of death were low output syndrome(n=3)，acute renal failure(n=2)， and multiple organ failure(n=1)．Nine patients needed reoperation for postoperative bleeding(12.00％)．We followed up 69 patients from 3 to 56 months (26.31±7.40 months). There were 2 patients with trivial residual shunt. The cardiac function status were New York Heart Association(NYHA) Ⅰ to Ⅱ in the 69 patients．No late death occured． Conclusion The effectiveness of surgical treatment for adults with tetralogy of Fallot is satisfactory．
Objective To discuss the effect of Balint groups on promoting mental health of oncology nurses through developing Balint group activities. Methods From December 2015 to December 2016, a series of Balint group activities were carried out among 63 oncology nurses in West China Hospital of Sichuan University. Huaxi Emotion Index was used to investigate the psychological status in the nurses before and after the activities of Balint groups, and then the data was analyzed statistically. Result Except the scores of nurses aged over 41 and nurses above the primary and secondary level (P>0.05), all other scores had significant differences (P<0.05). Conclusions Balint group activities can significantly relieve oncology nurses’ negative emotions such as anxiety, tension and depression, alleviate body discomfort symptoms and improve interpersonal relationships. Huaxi Emotion Index is easy to understand, which helps rapid clinical assessment and nurses’ psychological problems screening. It is suitable for popularization and application clinically.
Due to the high incidence rate, high mortality rate, high disability rate, high recurrence rate and many complications of stroke, patients are easily re-admitted after discharge, which seriously affects their quality of life. A scientific and standardized discharge plan can ensure continuous medical care for stroke patients, reduce readmission rates, and improve patient outcomes, which is of great significance for reducing the burden of stroke. This paper reviewes the development and connotation, the nursing model and the implementation status of the discharge planning among stroke patients at home and abroad, and makes recommendations on the opportunities and challenges of implementing the stroke discharge plan, in order to provide a reference for scientific and standardized stroke disease management.
Wound infection can prolong wound healing time, increase hospitalization cycle and readmission rate, seriously affect patients’ quality of life and increase economic expenditure. Timely and accurate identification and management of wound infections is key to promoting wound healing and maximizing cost-effective management. In 2022, the International Wound Infection Association published the third edition of Wound Infection in Clinical Practice: Principles of Best Practice. The consensus incorporates new advances in research and clinical practice in the areas of wound environment, risk factors for infection, biofilms, antibiotic resistance, and the identification and management of wound infections, and provides detailed approaches to infection assessment and management. This article introduces the key elements of the 2022 expert consensus and interprets the updated content to help healthcare professionals, patients, caregivers, and policy makers understand the latest consensus document, promote its clinical application in the prevention and treatment of wound infection, and better improve the quality of clinical practice.
