Objective To investigate the status quo of oral nursing in the emergency department of top three hospitals in Shanxi province, and to analyze the existing problems so as to provide the basis and reference for improving the clinical operation standard. Methods In the form of WeChat questionnaire, a questionnaire survey was conducted to investigate 190 nurses who met the requirements in emergency departments of 6 top three hospitals in Shanxi province. Results All the 6 hospitals surveyed did not incorporate oral care into the nurse examination program; 28.42％(73/190) of the subjects had oral assessments of endotracheal intubation according to their clinical experience;chlorhexidine (70.00％,133/190) and physiological saline (65.79％,125/190) were the most commonly used oral care solutions in clinic;48.42％(92/190) of nurses performed this operation for 6-10 min;91.58％(114/190) of nurses believed that oral care played an important role in the recovery of these patients. Conclusions The oral care and oral care of the patients in the emergency department are mostly clinical experience, so it is urgent to establish a unified standard of implementation on the basis of evidence. The professional knowledge of oral nursing of the patients undergoing oral trachea intubation is low, so it is suggested that the training of emergency nurses be strengthened and the operation should be included in the assessment of nursing operations.

Objective:To investigate the diagnostic efficacy of miR-9 and miR-195-3p for primary hepatic carcinoma (PHC), and the changes in miR-9 and miR-195-3p levels after interventional therapy.Methods:A total of 123 cases of PHC patients and 30 cases of liver cirrhosis patients attending Tangshan People's Hospital from May 2019 to May 2020 were selected as the PHC group and the liver cirrhosis group, respectively, and 50 people who were physically healthy during the same period were selected as the healthy group. Serum miR-9 and miR-195-3p levels were detected by real-time quantitative PCR. The relationship between serum miR-9 and miR-195-3p levels and clinical-pathological characteristics of PHC patients was analyzed. Receiver operator characteristic (ROC) curve was applied to analyze the diagnostic efficacy of miR-9 and miR-195-3p for PHC. The changes in serum miR-9 and miR-195-3p levels in PHC patients before and after transcatheter arterial chemoembolization (TACE) were compared.Results:There were statistically significant differences in serum miR-9 (0.99±0.10, 1.31±0.28, 1.68±0.43) and miR-195-3p (0.97±0.10, 0.83±0.22, 0.63±0.18) levels among the healthy group, liver cirrhosis group, and PHC group ( F=69.78, P<0.001; F=74.82, P<0.001), with serum miR-9 levels increased successively and miR-195-3p levels decreased successively among the three groups (all P<0.05). There were statistically significant differences in serum miR-9 ( t=7.45, P<0.001; t=5.32, P<0.001; t=4.96, P<0.001) and miR-195-3p ( t=16.17, P<0.001; t=4.21, P<0.001; t=7.53, P<0.001) levels in PHC patients with different maximum diameters of tumor, clinical stages and degrees of differentiation. ROC curve analysis showed that the area under the curve (AUC) for the combined differential diagnosis of liver cirrhosis and PHC by serum miR-9 and miR-195-3p testing was 0.919, which was higher than the AUC for the differential diagnosis of serum miR-9 (AUC: 0.712, Z=4.38, P<0.001) and miR-195-3p (AUC: 0.844, Z=2.04, P=0.042) alone. After TACE treatment, serum miR-9 levels decreased (1.39±0.21 vs. 1.68±0.43, t=14.22, P<0.001) and miR-195-3p levels increased (0.78±0.22 vs. 0.63±0.18, t=14.84, P<0.001) in patients compared to pre-treatment levels. Conclusion:Serum miR-9 level is increased and miR-195-3p level is decreased in patients with PHC compared with patients with liver cirrhosis and healthy subjects, and the combination of the two has high differential diagnostic efficacy for liver cirrhosis and PHC. After TACE treatment, serum miR-9 level is decreased and miR-195-3p level is increased in PHC patients.

Objective To assess the feasibility of low concentration contrast medium (270 mgI/ml) and low radiation dose (100 kV) for enhanced CT scanning in infants and young children abdominal CT examination.Methods Ninety children with abdomen tumors or abdominal injuries who underwent contrast-enhanced CT examination were selected.The patients were divided into 3 groups (each n＝ 30):Group A with tube voltage of 120 kV for non-contrast enhanced and parenchymal phase scanning and iodixanol contrast-medium (320 mgI/ml);group B with tube voltage of 100 kV for non-contrast enhanced and parenchyrnal phase scanning and iodixanol contrast-medium (270 mgI/rnl);group C with tube voltage of 100 kV for non-contrast enhanced and parenchymal phase scanning and iodixanol contrast-medium (270 mgI/ml).The 4-point scale was used to evaluate the quality of parenchymal phase imaging.The standard difference (SD) of CT value in subcutaneous fat,SNR and CNR of liver parenchyma,splenic parenchyma,renal cortical,renal vein,and abdominal aorta were measured at parenchymal phase,and CT dose index of volume (CTDI,ol),dose length product (DLP) and effective dose (ED) were recorded.The data were statistically analyzed among 3 groups.Results There was no significant difference of SNR,CNR nor objective scores of liver parenchyma,splenic parenchyma,renal cortical,renal vein and abdominal aorta among 3 groups (all P＞0.05).The differences of CTDIvol,DLP and ED among 3 groups were statistically significant (all P＜0.01).The CTDIvol had no statistical difference between group B and group C (P ＝ 0.001,0.002),DLP (P ＝ 0.013,0.004) and ED (P ＝ 0.03,＜0.001) of group A had statistical difference with those of group B and C.Conclusion CNR of the abdominal image can be guaranteed using low concentration contrast medium (270 mgI/ml) combined with 100 kV tube voltage for CT scanning of infants and young children,therefore satisfying clinical diagnostic requirements.
