ObjectiveTo investigate the incidence of medical adhesive-related skin injuries (MARSI) and analyze its influencing factors among elderly patients, in order to provide reference for its prevention. MethodWe carried out a cross-sectional descriptive study in the Department of Geriatrics of a class-3 grade A hospitals in Sichuan Province between June 1 and July 31, 2015. Totally, 288 patients aged from 62 to 95 years [with the average of (82±13) years] met the inclusion criteria of the study. We analyzed the MARSI situation of the patients, and at the same time, we surveyed 126 nursing workers on their knowledge about MARSI. ResultsThe number of patients with MARSI was 37, and the incidence was 12.85%. The difference of Braden scores between patients with and without MARSI was statistically significant (P<0.001) . About 70% of the nursing staff knew little about MARSI. ConclusionsWe should pay attention to MARSI, improve nurses' knowledge and explore scientific preventive measures.
ObjectiveTo summarize clinical experience of minimally invasive non-thoracoscopic Nuss procedure for the treatment of pectus excavatum (PE). MethodsFifty-one pediatric patients received minimally invasive nonthoracoscopic Nuss procedure for PE between July 2008 and February 2014 in Department of Thoracic Surgery, Jinan Military General Hospital. There were 32 males and 19 females with their average age of 8.32 (2.5-17.0) years. Transverse incisions were made in bilateral chest wall. Supporting plate was put to right chest wall through retrosternal approach, turned over and fastened onto the ribs. ResultsDeformity of all the patients was successfully corrected. Operation time was 30-52 (38±9) minutes. One patients had heart injury which was repair after open thoracotomy, and then supporting-plate was successfully secured. Postoperative complications included subcutaneous emphysema in 7 patients, pneumothorax in 3 patients and atelectasis in 3 patients, all of whom were cured by conservative treatment. Supportingplate transposition occurred in 1 patient and was corrected by reoperation. All the patients were followed up for 1-42 (21.6±7.6) months. According to Nuss standard, there were 39 patients with excellent results, 9 patients with good results, and 3 patients with fair results. ConclusionMinimally invasive Nuss procedure is an efficacious, easy, feasible and safe procedure for the treatment of PE with low morbidity.
ObjectiveTo study the expression of cytokine-induced neutrophil chemoattractant-1(CINC-1)in rats with transfusion-related acute lung injury(TRALI),explore its possible role in the pathogenesis of TRALI. MethodsSixty Sprague-Dawley rats were randomly divided into a normal control group with sham operation,a positive control group with ALI induced by intravenous infusion of lipopolysaccharide(5 mg/kg),and a TRALI group treated by intraperitoneal injection of LPS 2h before the transfusion of human plasma (1mL),a LPS control group treated by intraperitoneal injection of LPS 2h before the transfusion of normal saline(1mL).The reverse transcription-polymerase chain (RT-PCR)was used to detect CINC-1 mRNA.The level of CINC-1 in lung tissue homogenate was measured by ELISA.Morphological changes of the lung tissue were observed under light microscope.Myeloperoxidase (MPO)in lung homogenate and wet lung weight to dry lung weight ratio (W/D)were observed.The number of cells and the percentage of polymorphonuclear neutrophil (PMN)in Bronchoalveolar lavage fluid (BALF)were also compared. ResultsCompared with the normal control group and the LPS control group,the expression of CINC-1 protein and CINC-1 mRNA were increased significantly in lung of the positive control group and the TRALI group(P<0.05).The number of cells and the percentage of PMN in BALF of the TRALI group [(310.63±76.67)×106/L and (33.57±11.51)%] were significantly higher than those in BALF of the normal control group [(101.36±63.83)×106/L and (9.87±3.56)%](P<0.05).Tissue water content and MPO activity in the TRALI group were significantly higher than those in the normal control group (P<0.05). ConclusionExpression of CINC-1 protein and CINC-1 mRNA are increased in the rat lung with TRALI and PMN infiltration in lung tissue,which suggests CINC-1 participate in the process of the PMN and endothelial cell adhesion and may play an important role in the pathogeneses of TRALI.
