Methods The clinical data of 120 patients who underwent coronary stenting between January and March 2011 were retrospectively analyzed. Patients were randomly divided into control group (n=58) treated with conventional coronary stent extubation and experiment group (n=62) treated with conventional coronary stent extubation and professional nursing intervention care. Results In 120 patients, VVRs occurred in 10 including 8 in the control group and 2 in the experiment group. The difference between the two groups was significant (Plt;0.05). Conclusion The coronary stent implantation with specific nursing interventions can effectively reduce the vascular vagal reflex, and leads to a higher success rate of the surgery.
Objective To explore the influence of applying the fast-track surgery (FTS) to optimize the process in the perioperative period of cardiac intervention on the rehabilitation of patients with radial artery stenting surgery. Methods A total of 190 patients with radial artery stenting surgery in the Department of Cardiology, West China Hospital from June 2017 to May 2018 were enrolled. They were randomized into a control group (n=95) and a FTS group (n=95) by random umber table. There were 60 males and 35 females aged 35-88 (65.2±9.6) years in the control group as well as 62 males and 33 females aged 34-86 (61.5±11.3) years in the FTS group. Patients in the control group received routine perioperative care, but patients in the FTS group received individual precision interventions by applying the FTS concept to optimize the process of perioperative care, including individual care management before being admitted into hospital, during hospital, and after discharge from hospital. Duration of hospital stay, satisfaction scores, number of comorbidities after surgery, disease self-management ability, and readmission rates were compared between the two groups. Results Compared to the control group, the FTS group had significantly shorter duration of hospital stay, less comorbidities, higher satisfaction scores and disease self-management ability, and lower readmission rate to hospital (P<0.05). Conclusion Applying FTS into the perioperative period of cardiac interventions to optimize its process can help patients recover from radial artery stenting surgery, increase patients’ self-management abilities, shorten duration of hospital stay and decrease comorbidities and cardiac adverse events.
Objective To study the transfection and expression of pleiotrophin (Ptn) gene in mice adipose-derived stem cells (ADSCs) so as to provide a new approach for the treatment of ischemic injury. Methods ADSCs from clean inbred C57BL/6W mice (weighing, 15-20 g) were isolated and cultured in vitro. The cell surface markers (CD29 and CD44) of ADSCs were identified by flow cytometry. The ADSCs were transfected with plasmid pIRES2-LEGFPN1 (containing Ptn gene coding sequence) as experimental group (group A) and with plasmid pLEGFP-N1 (containing GFP gene coding sequence) as control group (group B). After ADSCs were transfected by different plasmids respectively, the cells containing Ptn gene were selected by G418 (the best selected concentration was 200 μg/mL), and the immunophenotype of the cells was identified by flow cytometry after transfection. Meanwhile, real-time fluorescence quantitative PCR and Western blot were used to analyse the expression levels of Ptn mRNA and PTN protein in selected cells. Results The mice ADSCs were isolated and cultured successfully in vitro. The positive rates of the cell surface markers CD29 and CD44 of ADSCs were 99.5% and 95.8%, respectively; the double positive rate of CD44 and CD29 was 93.6%. The positive rates of the cell surface markers CD29 and CD44 of ADSCs were 99.1% and 95.6%, respectively after transfection of Ptn gene; the double positive rate of CD44 and CD29 was 93.4%. The expression levels of Ptn gene and PTN protein in group A were significantly higher than those in group B (P lt; 0.05). Conclusion The ADSCs can be stablely transfected by Ptn gene, the transfected ADSCs can express PTN protein highly, which is a new idea for tissue engineering of vascular reconstruction.
ObjectivesTo evaluate the reporting quality of individual/focus group interviews published in nursing journals included in the Chinese science citation database (CSCD).MethodsCSCD database was electronically searched to collect qualitative studies published in nursing journals included in CSCD from January 2016 to December 2018. Two researchers independently screened literatures, extracted data, and assessed the quality of included studies by COREQ guidelines, SPSS 25.0 software was then used for statistical analysis.ResultsA total of 223 qualitative researches were included. The results of COREQ evaluation showed that full report rate of 43.8% (14/32) studies were less than 50%, 78.6% (11/14) were less than 20%, and the full report rate of item 4 was even 0%. There were no significant differences between different total cites and the availability of funding in COREQ guidelines.ConclusionThe reporting quality of the qualitative researches published in the four nursing journals included in the CSCD requires further improvement. Therefore, we suggest that domestic nursing journals should introduce COREQ guidelines in contribution and strictly implement it in editorial review and peer review.
Objective To investigate the constituent ratio and clinical features of diffuse interstitial lung disease（DILD） in Chongqing city.Methods Data was collected from all patients diagnosed as DILD in five comprehensive teaching hospitals in Chongqing from 2002 to 2006.The disease constituent ratio of DILD in the respiratory department or in the whole hospital was analysised.Meanwhile the clinical manifestation and the laboratory examination such as lung function and biopsy were also analysised.Results Mean age of DILD patients is （61.65±13.31）years with a ratio male to female of 1.83.The constituent ratio of DILD were 2.83‰ in respiratory department and 0.30‰ in hospital in 2002，and increased to 8.29‰ and 0.48‰ respectively in 2006.Graticule（62.20%）and honeycombing（24.50%） were predominant imaging manifestations.47.55% patients had restrictive lung function impairment，and 51.05% had mixed lung function impairment.Pathologic examination revealed UIP as the most common type，however，81.82% cases could not be classified to any category pathologically.Conclusions The prevalence of DILD increased progressively from 2002 to 2006.A definite diagnosis of DILD demands cooperation of physicians，radiologists and pathologists.
Objective To explore the imaging features of acute exacerbation of idiopathic pulmonary fibrosis ( IPF) under high-resolution computed tomography ( HRCT) . Methods The HRCT imaging features of six patients who met the criteria for acute exacerbation of IPF were analyzed retrospectively. Results The manifestations of IPF on HRCT scan were various in forms and distribution, as multifocal, ground-glass opacity, reticular shadow, honeycombing densities, capillary bronchiectasis,subpleural lines, traction bronchiolectasis and emphysema. The characteristic lesions were newly diffuse bilateral ground-glass opacity at the time of acute exacerbation, superimposed on subpleural reticular and honeycombing densities. Conclusions Chest HRCT findings in acute exacerbation of IPF are characteristic.HRCT is accurate and superior in diagnosis of IPF and in determining acute exacerbation of IPF.
Objective To investigate the effects of immunoliposomes containing vasohibin on pulmonary fibrosis in mice. Methods Liposomes containing vasohibin plasmids were prepared by reverse phase evaporation technique, then combined with VWF antibody to form the immunoliposomes. 30 mice were randomly divided into a control group, a model group, and a vasohibin group. The mice in the model group and the vasohibin group were nasally instilled with bleomysin to induce pulmonary fibrosis. After 3 days, the mice in the vasohibin group were nasally instilled with the immunoliposomes containing vasohibin. The mice were all sacrificed after 14 days. Lung tissue sections were stained by HE and CD31 immunohistochemistry staining. The level of hydroxyproline in lung was measured by colorimetry. Results The resultsdemonstrated that the vasohibin immunoliposome could markedly decrease angiogenesis with the number of ( 46 ±16) compared to ( 78 ±12 ) , and decrease fibroblast proliferation with ( 0. 84 ±0. 12) μg/mg compared to ( 1. 39 ±0. 23) μg/mg. Conclusion The vasohibin immunoliposome can attenuate pulmonaryfibrosis and provide a novel strategy for clinical application in the future.
Objective To systematically review the efficacy of long-acting antibacterial material in the prevention of secondary urinary infection. Methods PubMed, The Cochrane Library, CNKI, CBM, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of long-acting antibacterial material in the prevention of secondary urinary infection from inception to November, 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software. Results A total of 16 RCTs were included. The results of meta-analysis showed that: the long-acting antibacterial material group was superior to the general intervention group in morbidity of secondary urinary infection (Peto OR=0.17, 95%CI 0.13 to 0.23, P<0.000 01), and bacterial positive rate of secondary urinary infection (Peto OR=0.15, 95%CI 0.08 to 0.27,P<0.000 01). Conclusion Current evidence shows that long-acting antibacterial material can effectively reduce the infection rates of secondary urinary infection. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
