Objective To observe the efficacy of extracorporeal liver support by using less fresh frozen plasma in the treat‐ment of acute‐on‐chronic liver failure.Methods A total of 45 patients with acute‐on‐chronic liver failure were divided into ob‐servation group[plasma perfusion(PP) with a small amount of plasma+ plasma exchange(PE)] ,control group 1(PE) ,control group 2(PP+PE)in terms of the amount of plasma used on the day of treatment. All the patients received artificial liver treatnts 62 times totally.Results The clinical symptoms were improved in the three groups after treatments.There were significant differences in the decrease of alanine transaminase (ALT) ,aspartate transaminase(AST) and direct bilirubin(DBil)rather than the decrease of total bilirubin(TBil)and blood ammonia among the groups.No significant difference was noted in the liver and kidney function among the three groups. The improvement of the coagulation function was poor in the observation group when compared with the control group 1 and control group 2 and there were significant differences.Conclusion During the short sup‐ply of the plasma ,plasma perfusion combined with small amount of plasma can be considered to be used in artificial liver treat‐ments ,which can effectively decrease the level of TBil ,relieve symptoms and decrease the occurrence of complications.

This paper was aimed to study the protective effects and related mechanisms of Zhen-Gan Xi-Feng (ZGXF) decoction containing serum on 6-OHDA-induced oxidative stress in PC12 cells.The ZGXF decoction containing rat serum with low-,medium-,and high-dose (8,16,or 32 g.kg-1) or blank serum was used to preprocess PC12 cells for 1 h,and cultured together with 100 μM 6-OHDA for 24 h.And then,cells were collected.The fluorescent probe 2',7'-dichlorofluorescin diacetate (DCFH-DA) and fluorescence microplate reader were used to detect the level of reactive oxygen species (ROS).Real-time quantitative PCR was used to analyze the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2),Nfe2l2,heme oxygenase-1 (HO-1),glutamate-cysteine ligase catalytic subunit (GCLc),and GCL modulatory subunit (GCLm).The luciferase report gene system was used to detect the antioxidant response element (ARE) activation.The results showed that ZGXF decoction-containing serum inhibited the 6-OHDA-induced oxidative stress,upregulated the Nfe2l2,HO-1 and GCLc mRNA expressions in cells processed with 6-OHDA.However,it has no significant effect on GCLm mRNA expression.It was concluded that ZGXF decoction-containing serum had protective effects on 6-OHDA-induced oxidative stress in PC 12 cells.Its mechanism may be correlated with the upregulation on Nfe2l2 mRNA expression,which activated ARE and further induced its downstream gene of phase Ⅱ detoxifying enzyme,as well as the HO-1 and GCLc mRNA expressions of antioxidant enzyme gene.

Objective To investigate the effects of human umbilical cord mesenchymal stem cells (UC-MSCs) on vascular endothelial growth factor (VEGF) and interleukin-6 (IL-6) expression in acute myocardium infarction (AMI) rats. Methods The human UC-MSCs were cultured to the 4th generation for experiment. Sixty male Sprague-Dawley (SD) rats were randomly divided into sham group, AMI model group and UC-MSCs group, with 20 in each group. AMI animal model was produced by ligation of anterior descending coronary artery; in the sham group, the threading vein was gone below without ligation. In UC-MSCs group 2×106 UC-MSCs were infused through the caudal vein at 24 hours after successful model production. The animals were sacrificed after 7 days; the myocardial tissue and coronary artery below the ligation line were harvested. The mRNA and protein expressions of IL-6 in myocardium were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western Blot. The positive expression of VEGF in coronary artery was observed by immunohistochemisty. Results Compared with the sham group, the mRNA and protein expressions of IL-6 in myocardium in AMI model group were increased significantly (gray value: 0.732±0.131 vs. 0.321±0.080, 0.678±0.191 vs. 0.286±0.061, both P < 0.05). Compared with the AMI model group, the mRNA and protein expressions of IL-6 in myocardium in UC-MSCs group were decreased significantly (gray value: 0.300±0.104 vs. 0.732±0.131, 0.312±0.101 vs. 0.678±0.191, both P < 0.05). Observation under light microscope, the VEGF positive cells in AMI model group was increased significantly compared with the sham group (cells/HP: 21.1±2.2 vs. 7.6±1.3, P < 0.05), the VEGF positive cells in UC-MSCs group were increased significantly compared with the AMI model group (cells/HP: 41.5±3.1 vs. 21.1±2.2, P < 0.05). Conclusion Human UC-MSCs could promote angiogenesis by the improvement of VEGF in coronary artery and inhibit the inflammation by the reduction of IL-6 in rats with AMI.

Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.

Objective To investigate and analyze the status quo of professional identity of nursing students with different educational backgrounds.Methods With stratified-cluster random sampling,635 students were surveyed using the nursing students' professional identity questionnaire.Results The total score of professional identity of junior college nursing students was significantly higher than that of undergraduate students.Junior college nursing students had a higher score in professional knowledge dimension than undergraduate and graduate students,while the score of nursing undergraduate students was higher than that of graduate students.Junior college nursing students had a higher score in professional will dimension than undergraduate and graduate students.Nursing graduate students had a higher score in professional expectation dimension than junior college and undergraduate students,while the score of undergraduate students was higher than that of junior college students.Whatever the educational background,professional skill and professional expectation were the top two dimensions,while professional knowledge and professional emotion were the last two dimensions.The difference was statistically significant between the answers of nursing students with different educational backgrounds to the following questions,such as which is the most probable factor affecting your learning enthusiasm,who has the greatest impact on your professional thought about nursing and which nursing field are you most willing to go in for.There was significant difference in professional identity score between different grades of junior college and undergraduate nursing students,while there is no significant grade difference in graduate students.Conclusions There were some differences of professional identity of nursing students with different educational backgrounds.Nursing educators should carry out the professional education according to the student's educational backgrounds.

Objective To study the feasibility of noninvasive detection of unstable plaques with ~(18)F-Fluorodeoxyglu-cose (~(18)F-FDG) PET/CT imaging. Methods Atherosclerotic plaques were induced in male New Zealand white rabbits. Animals were injected with FDG labeled with ~(18)F, then examined with PET/CT. Aorta was explanted for photography with digital camera, and ~(18)F-FDG uptake analysis. Thirty unstable plaques and 30 stable plaques were choosed so as to compare the quantitativly ~(18)F-FDG uptake. The number of macrophages and smooth muscle cells was detected by immunohistochemical technique. Results Experimental group showed inconsistent uptake of ~(18)F-FDG in the abdominal aorta. The results were confirmed in the ex vivo digital photo of the explanted aorta. The target to non target ratio (T/NT) and macrophages of unstable plaques were higher than stable plaques (P<0.01) , but smooth muscle cells obviously reduced (P <0. 01). Correlation analysis showed that there was a positive correlation between T/NT and macrophage content (r=0. 815,P<0. 01), and a negative correlation between T/NT and SMC content(r=-0. 684,P <0. 01). Conclusion ~(18)F-FDG PET/CT can constitute an attractive imaging method for the noninvasive detection of experimental unstable plaques.
