ABSTRACT
Objective To understand the status and influencing factors of benefit finding in patients with cancer.Methods 350 patients with cancer were collected with convenience sampling method from two Jiangsu hospitals.All patients received a questionnaire survey.Multiple linear regression analysis was used to analyze the influencing factors of benefit finding in patients with cancer.Results (1) The score of benefit finding in patients with cancer was statistically significant in different frequency of physical exercise (F=8.37,P=0.00),different character (F=3.04,P=0.04) and different educational level (F=2.91,P=0.03).(2) There was a positive correlation between benefit finding(78.53± 10.50) and communication with physicians(7.27±2.19),medical coping(43.48±4.50),optimism(17.33±2.24) and social support(44.81±3.91)(r=0.31,0.35,0.29,0.23,all P＜0.05) in patients with cancer.The benefit finding in patients with cancer was negatively correlated with depression(8.59± 1.83) (r=-0.37,P＜0.05).(3) Multiple linear regression analysis results showed that medical coping modes-confrontation,objectively social support and utilization,physical exercise,depression,communication with physicians and character were the factors influencing benefit finding in patients with cancer(△R2 =28％,P＜ 0.05;△R2 =5.5％,P＜ 0.05;△R2 =3.1％,P＜ 0.05;△R2 =1.9％,P＜0.05;△R2 =1.7％,P＜0.05;△R2 =1.0％,P＜0.05;△R2 =1.1％ P＜0.05),which explained 42.0％ of the total variance.Conclusion Medical coping modes-confrontation,objectively social support and utilization,physical exercise,depression,communication with physicians and character are the factors influencing benefit finding in patients with cancer.
ABSTRACT
BACKGROUND: The main reason for the postoperative loosening of cemented prosthesis is interfacial debonding and bone cement internal damage. Most studies have suggested that both of them occur in the process of fatigue damage, however, little is reported on primary loading that results in the initial damage to the bone cement-stem interface and inside of bone cement. OBJECTIVE: To study the mechanical properties of bone cement-stem interface, and the effect of crack formation in bone cement on interfacial loosening. METHODS: The cement-titanium al oy handle implant components were prepared. The maximum adhesive force of bone cement-stem interface was measured using push-in experiment. The cement damage and crack in the process of bone cement-handle interfacial debonding were monitored online using acoustic emission tester. The non-destructive testing on the metal surface and the inner layer of bone cement cylinder was conducted using three-dimensional surface profiler, ultrasonic microscopy and X-ray detector. RESULTS AND CONCLUSION: The online monitoring results of debonding experiment and acoustic emission tester demonstrated that the initial damage of bone cement initiated in the primary loading of patients after operation, rather than at fatigue damage stage. Bone cement coffin caused cracks initiation mainly due to the combination effect of radial and axial stress. The bone cement-stem interfacial shear lag effect could not prevent the gradual extension of interface and inner coffin crack from top to bottom. The bone cement defects formed in solidification process was likely to affect the mechanical properties of the material, and eventual y induced the crystal face and macromolecular chain fractures, forming silver striated cracks and leading component failure.
ABSTRACT
Objective To define the concept of the benefit finding of breast cancer patients by Morse,Hupcey and Penrod's developed analytical methods.Methods Twenty-two references were recruited through the databases of Medline,Cochrane Library,Embase,Web of Science,ProQuest,according to the inclusion and exclusion criteria.Coding related content of literatures based on the concept of property from Morse terms:boundaries,preconditions and outcome,and from the epistemological,pragmatics,linguistics,logic perspective to evaluate the maturity of the concept.Results The benefit finding of breast cancer patients involved a perception of cognitive processes,including the three attributes,three word boundaries,two preconditions and three results.Development of the concept was not fully mature.Conclusions Clarifying the benefit finding of breast cancer patients can help researchers use the techniques and principles of positive psychology to promote the benefits finding of breast cancer patients and the patients' physical and mental rehabilitation.
ABSTRACT
Objective To evaluate the effect of preoperative ambroxol aerosol inhalation on postoperative lung complications in patients with chest and abdominal surgery.Methods The randomized controlled trials (RCTs) taking preoperative ambroxol aerosol inhalation interventions were collected from the databases of Chinese Technology Journal Database,China National Knowledge Internet and Wanfang Database.Data were analyzed with RevMan 5.0 software.Results Eleven articles with 1 160 patients met the inclusion criteria.There was a certain heterogeneity across the analysis,which might result from kind of included patients,inhalation method,difference of the medication,inhalation time,etc,according to subgroup analysis.The result showed that compared with the control group,patients in the experimental group had lower incidence of postoperative lung complications and the differences were not statistically significant.Conclusions The Meta analysis had identified a significant effect of preoperative ambroxol aerosol inhalation on postoperative lung complications in patients with chest and abdominal surgery,but high quality were in need.
ABSTRACT
Objective To compare the preoperative eternal nutrition bowel preparation method with the conventional method in the intestinal cleansing effect,postoperative infection and postoperative complications of gastrointestinal function recovery time,and to provide reference for selection for our clinical preoperative practice.Methods Computer Retrieval of Chinese Biomedical Literature Database,VIP Chinese Science and Technology Journal Full-text Database and China Academic Journal was conducted.The time limit was from establishment of database till May 2013.The research type was randomized controlled trial.Two investigators independently screened,assessed quality and extracted data according to the inclusion and exclusion criteria for literatures,and cross-checked them using RevMan 5.0 software for Metaanalysis,then applied the grading method recommended by the GRADE grading system.Results Ultimately seven RCTs were included,with a total of 478 cases of colorectal cancer patients.Compared with conventional preoperative bowel preparation,eternal nutrition method showed similar bowel cleansing effects and the incidence of complications,but it could shorten the postoperative recovery of gastrointestinal function time,lower positive rate of abdomen,intestine shedding of tumor cells,improve postoperative albumin and transferritin levels.Conclusions Eternal nutrition alternative method for bowel preparation before colorectal surgery is safe and effective.
ABSTRACT
BACKGROUND:As lumbar spine biomechanics research is unceasingly thorough and the constant development of related fusion and dynamic fixation device, the spine fusion technique which is represented by artificial disc replacement is a new choice to the spine surgeons. Therefore, it is particularly important to design reasonable artificial intervertebral disc. OBJECTIVE:To establish the finite element model of the new artificial disc replacement of the lumbar motion segment for further biomechanical study. METHODS:The L3-4 thin-section CT images of a healthy male volunteer was selected, combined with human anatomy data and applied the reverse engineering technology to rebuild the lumbar spine model with medical image software Mimics and tool software Geomagic Studio. The three-dimensional model of the silicone artificial disc was converted into a finite element model through software ANSYS12.0. RESULTS AND CONCLUSION:Through CT scanning, digital image processing and computer-aided design, the three-dimensional model of the lumbar motion segment and the finite element model of artificial disc replacement were successful y established. The finite element model contained 691 085 units and 1 008 913 nodes which could be applied constraint and load and could be used for spinal biomechanics and the further research of the new artificial intervertebral disc.
