Objective:To explore the factors influencing patient safety behavior of nursing students during clinical practice.Methods:A cross-sectional study was used, in which a total of 214 participants completed the online survey related to the undergraduate nursing students ′ clinical teaching satisfaction scale, safety attitude questionnaire and nurse safety behavior questionnaire. Results:The mean scores of clinical teaching satisfaction, safety attitude and nurse safety behavior were (3.83±0.81), (3.70±0.65) and (3.93±0.79) respectively. There were positive correlations between clinical teaching satisfaction, safety attitude with the nurse safety behavior ( r=0.82, 0.75, P<0.01). The results also showed that the same shifts with their clinical instructors, clinical teaching satisfaction and safety attitude could affect safety behavior of nursing students ( F=67.81, R2=0.753, ΔR2= 0.742, P=0.00), which accounted for 74.20% of total variation. Conclusions:The same shift arrangement for both clinical instructors and nursing students, enhancement of the demonstration and guidance from clinical instructors, as well as strengthening the cultivating patient safety attitude would be beneficial to promoting the safety behavior of nursing students during clinical practice.

ObjectiveTo investigate the effects of different amounts of iodine intake on the cellular and humoral immune in Grave's disease (GD) patients.MethodsThe clinical GD cases were diagnosed by thyroid fine needle Cytology examination.Patients in GD group are divided into GD group Ⅰ and GD group Ⅱ based on the median of urine iodine.The blood levels of FT4,FT3,TSH,TPOAb,TGAb,TRAb and TNF-t were detected.The difference and association of these parameters between these groups were analyzed.ResultsThe TNF-αt level in GD Ⅰ group was higher than that of GD Ⅱ group( P ＞ 0.05 ) ;The average level of TRAb of GD Ⅰgroup ( [ 1.4 ±0.2 ] U/L) were higher than that of GD Ⅱ group ( [ 1.2 ± 0.1 ] U/L) ( P ＜ 0.05 ) ;The positive rates of TGAb and TPOAb of GD Ⅰ group were higher than that of GD Ⅱ group ( P ＜ 0.05 ).The percentages of patients with high level of TGAb and TPOAb in GD Ⅰ group ( 78.9％ 、84.2％ ) were higher than that in GD Ⅱ group (50.0％,62.5％ ) ( x2 =6.79,10.70,P ＜0.05 ) ; Analysis showed a linear positive correlation of TNF-αwith TRAb and TPOAb ( r is 0.489 and 0.563,P ＜ 0.01 ).ConclusionIodine is an important factor to the development of Graves disease.Excessive iodine intake will exaggerate the GD condition and patients with GD should be controlled for iodine intake.

Objective To investigate the current status of treatment on traumatic ruptured spleen in a regional medical center in Tianjin,China.Method Logistic analysis of 16 impact ffactors of treatment decision on 147 patients with traumatic ruptured spleen.Results The type of trauma,pulse rate at admission,result of abdominal puncture and CT grade were related to treatment decision making.Splenectomy was carried out in 89 patients (60.54％) which accounted for 89.90％ of all surgical procedures.Splenectomy was carried out in 50.85％ of patients with CT grade 1 or 2 (or 85.71％ of grade 1 and 2 surgery),and 100％ of CT grade 3 or 4.Spleen preservation surgery was carried out in 7 patients with CT grade 1 or 2.Conclusion Splenectomy was carried out in most cases in this study.It is necessary to investigate the treatment of splenic trauma in regional medical centers,and to develop more reliable surgical techniques to carry out more spleen-preservation surgery ffor CT grade 1 or 2 ruptured spleen.

OBJECTIVETo develop and evaluate a mouse model of nonalcoholic steatohepatitis (NASH) induced by a high-fat and high-fructose (HFHFr) diet.

METHODSSix-week-old C3H mice were randomly divided into groups for HFHFr diet experimental modeling, high fat-only (HF) diet controls, high fructose-only (HFr) diet controls, and standard chow (SC) diet controls. The standard HFHFr diet was modified so that it consisted of 76.5% standard chow, 12% lard, 1% cholesterol, 5% egg yolk powder, 5% whole milk powder, and 0.5% sodium cholate, along with 20% fructose drinking water. At the end of experimental weeks 4, 8, and 16, measurements were taken for the NASH-related parameters of body mass, serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), lipid profile, and wet liver weight (upon sacrifice). In addition, histological changes in the liver were evaluated by hematoxylin-eosin (HE) and oil red O staining. The significance of differences between groups was assessed by statistical analysis, using the

METHODSof t-test, Wilcoxon rank sum test, x2 test, F test or Fisher's test as appropriate.

RESULTSAs compared to the mice in the SC group at the corresponding time points, the mice in the HFHFr and HF groups showed significantly higher body mass and wet liver weight, as well as more extensive and robust lipid disposition in hepatic tissues as evidenced by oil red O staining. However, HE staining indicated that the HFHFr and HF groups had different degrees of macrosteatosis accompanied with intralobular inflammatory foci, with the former showing more remarkable NASH-related histological changes. Analysis at the end of week 16 showed that about 80% of the mice in the HFHFr group had developed NASH [nonalcoholic fatty liver disease (NAFLD) activity score (NAS): less than 5]. The levels of low-and high-density lipoprotein (LDL and HDL) cholesterol, as well as the levels of ALT and AST, were increased from the end of week 4 to the end of week 8 for the HFHFr and HF groups. At the end of week 16, the two groups differed in the extent of increase in total cholesterol and LDL and HDL cholesterol, with only the HFHFr group showing statistically significant changes. Specifically, at the end of week 16, the HFHFr group showed ALT levels of 108.5 +/- 93.34 U/L (F=5.099, P =0.005 vs. HF group: 44.30 +/- 35.71 U/L, HFr group: 46.70 +/- 17.95 U/L, SC group: 24.70 +/- 6.57 U/L), AST levels of 316.30 +/- 208.98 U/L (F=6.654, P=0.001 vs. HF: 132.12 +/- 75.43 U/L, HFr: 143.30 +/- 38.53 U/L, SC: 122.60 +/- 12.76 U/L), total cholesterol levels of 5.18 +/- 0.58 mmol/L (F=72: 470, P =0.000 vs. HF: 3.94 +/- 0.75 mmol/L, HFr: 2.30 +/- 0.50 mmol/L, SC: 2.02 +/- 0.24 mmol/L), HDL cholesterol levels of 3.05 +/- 0.49 mmol/L (F=25.413, P =0.000 vs. HF: 2.65 +/- 0.54 mmol/L HFr: 1.77 +/- 0.47 mmol/L, SC: 1.58 +/- 0.16 mmol/L), LDL cholesterol levels of 1.11 +/- 0.23 mmol/L (F =83.297, P =0.000 vs. HF: 0.72 +/- 0.17 mmol/L, HFr: 0.27 +/- 0.04 mmol/L, SC: 0.20 +/- 0.05 mmol/ L).

CONCLUSIONThe present study suggests that a mouse model of NASH can be successfully induced by a 16-week modified HFHFr diet.
