ABSTRACT

Objective:To explore the application value of establishing standardized mobile nurses in operation room in improving the quality of operation nursing and reducing the occurrence of adverse events.Methods:A total of 3 445 operations in the Eastern and Western surgical wards of Shengjing Hospital Affiliated to China Medical University from 2018 to 2019 were selected in this study. The surgeries performed in the eastern surgical wards were the experimental group ( n = 1 650), and the standardized mobile nurse operation mode was adopted. The surgeries performed in the Western surgical wards were the control group ( n=1 795) adopted the general operation management and cooperation mode. The differences of nursing quality score, incidence of adverse events and satisfaction of doctors and nurses under different operation modes were observed. Results:The scores of surgical preparation, instrument management, surgical safety, and environmental management in the quality of surgical care in the experimental group were 9.14±0.38, 9.42±0.37, 9.64±0.27, 9.64±0.27, respectively, which were higher than those of the control group 9.11±0.36, 7.99±0.33, 8.03±0.39, 7.98±0.79, the difference between the two groups was statistically significant ( t value was 2.379-139.712, P<0.05). The satisfaction rate of doctors in the test group was 97.33% (73/75), which was higher than 91.67% (52/60) in the control group, and the satisfaction rate of nurses in the test group was 99.00% (99/100), which was higher than 97.92% (90/96) in the control group. The difference between the two groups was statistically significant ( χ2 value was 5.530, 3.920, P<0.05). The incidence of adverse surgical events in the experimental group was 0.79%(13/1 650), which was less than 1.78%(32/1 795) in the control group, the difference was statistically significant ( χ2 value was 6.600, P<0.05). Conclusions:The establishment of mobile nurse database in the operating room can not only alleviate the current situation of human resource shortage in the operating room, improve the quality of surgical care and physician satisfaction, but also reduce the probability of adverse events.

ABSTRACT

Objective To evaluate the value of imaging examination and diagnosis of airway foreign body in children. Methods 218 of airway foreign bodies confirmed by bronchoscopy were retrospectively analyzed in terms of clinical and imaging data. Results 218 patients included 140 males and 78 females. Their ages ranged 6 months to 12 years(mean,19.2 months). All patients had conventional radiographs on frontal chest films,neck lateral films and fluoroscopy. 34 cases underwent 64-slice spiral chest CT examination. According to the location of the foreign bodies,29 cases were in throat and subglottic,55 cases in trachea and 134 cases in bronchus(79 cas-es in the right,55 cases in the left). According to the character of the foreign bodies,5 cases were metal,29 cas-es in bone,93 cases in peanuts,59 cases in seeds,22 cases in fruits and vegetables and 10 cases in others respec-tively. Thirty-fourcases showed a direct sign of the foreign body and 177 cases showed the indirect signs. 34 cases on CT examination directly were showed foreign body in the tracheal bronchi. The diagnostic accuracy of CT exami-nation was 100%. Conclusions X-ray photograph and fluoroscopy were the first choice for aspiratory foreign bod-ies in children. CT examination is an important supplementary method when conventional X-ray examination is neg-ative.

ABSTRACT

PurposePrimary chest wall rhabdomyosarcoma (RMS) is very rare with limited imaging characteristic studies in the literature. This paper analyzes the CT imaging features of chest wall RMS in children to improve the diagnostic accuracy.Materials and MethodsThe imaging data of contrast enhanced CT scan of pathology conifrmed chest wall RMS in ifve children were analyzed.ResultsThe lesion was located in the anterior chest wall in one case, in the posterior chest wall in two cases, and the lateral chest wall in two cases (axillary). The tumors were round or spindle in shape with shallow spiculation. Plain CT showed heterogeneous density with patchy low-density necrotic area in two cases, and homogeneous attenuation in three patients. In all ifve cases there was no calciifcation or fatty tissue. The tumor involvement of adjacent spinal canal was seen in one case. Visceral compression was evident including lung parenchyma in one case, heart and liver in one case. Tumor blood vessel growth was seen in two cases. All ifve lesions were adjacent to the ribs, humerus, scapula and the spine with bone destruction in one case. On contrast enhanced scan, all ifve cases demonstrated heterogeneous mild to moderate enhancement, more prominent in the periphery. There were enlarged feeding arteries. Necrotic areas did not enhance. In two cases there were pulmonary metastases. Pleural effusion and ascites were identiifed in one case. There was lymph node metastasis in one case.ConclusionThe CT manifestation of children's chest wall RMS for chest wall include large soft tissue mass, heterogeneous density, no calciifcation or fatty tissue, partial necrosis, adjacent tissue compression, lymph node or distant metastasis. Combining with clinical manifestations, comprehensive analysis of contrast enhanced CT imaging can improve diagnostic accuracy.

ABSTRACT

Secretory anti-gp96 scFv fragment was expressed in Pichia pastoris to obtain a small molecule antibody that specifically recognizes heat shock protein gp96. The gp96-scFv fragment gene was synthesized and cloned to Pichia pastoris expression plasmid pPICZa-A. Pichia pastoris X33 was electroporated with the linearized recombinant expression vector, and expression of gp96-scFv fragment was induced by methanol. The His-tagged recombinant protein was then purified by affinity chromatography and analyzed with SDS-PAGE and Western blotting assays. The biological activities of recombinant gp96-scFv fragment were determined by Western blotting, Immunofluorescence, ELISA and FACS assays. The gp96-scFv fragment was expressed successfully in Pichia pastoris. About 50 mg of recombinant protein could be purified from 1 liter of the Pichia pastoris culture supernatant. Its molecular weight was about 15 kDa. The gp96-scFv fragment could specifically bind to gp96 protein by Western blotting, immunofluorescence, ELISA and FACS analyses. Pichia pastoris-expressed gp96-scFv fragment specifically recognizes gp96 protein, which could be used for Western blotting, Immunofluorescence, ELISA and FACS analyses.
