ObjectiveTo investigate the protective effect of astragalosideⅣ pretreatment against liver ischemia/reperfusion (I/R) injury in mice.MethodsSixty male C57BL/6 mice were randomized into four groups (15 mice in each group):group A:sham surgery with saline injection,group B:sham surgery with astragalosideⅣ injection,group C:I/R group with saline injection,group D:I/R and astragalosideⅣ injection.Mice were pretreated by daily intraperitoneal injection of saline or astragalosideⅣ (24 mg · kg-1 · d-1 ) for one week.The mouse partial liver model of I/R injury was established,and samples were collected at the 24 h after the I/R injury.Serum ALT and AST levels were determined,the histologic changes were observed by H&E staining under the light microscopy,whereas the nuclear factor (NF)-κB was assessed with Western blotting.Serum IL-1β,IL-6,and TNF-α levels were measured by enzyme-linked immunosorbent assay (ELISA). ResultsSerum ALT and AST levels significantly decreased and the histological damage was significantly alleviated in astragalosideⅣ treated I/R group as compared with saline I/R group [ AST:C:(4290± 292) U/L vs.D:(2373± 416) U/L t =0.844 ; ALT:C:(4146±500) U/L vs.D:(2318±289) U/L t =7.08 P ＜0.05].In comparison with group 3,astragalosideⅣ reduced NF-κB nuclear expression.ELISA showed astragalosideⅣ significantly inhibit the levels of IL-1 β,IL-6,and TNF-α in the serum (IL-1β:t =10.04;IL-6:t =6.281;TNF-α:t =6.817; P ＜0.05).ConclusionsPretreatment with astragaloside Ⅳ effectively protect against liver ischemia/reperfusion injury in mice.

Objective To investigate the treatment and clinical outcomes in developmental dislocation of the hip in chil?dren above 8 years old. Methods We retrospectively reviewed the results of operation treatment for developmental dislocation of the hip in 94 children (112 hips) from 2006 to 2012. The age of the patients ranged from 8.2 to 13.6 years at the time of treatment, with an average age 9.8 years. In 94 patients, there are 18 males and 76 females. The patients were classified into three group based on the age at time of operation:Group 8-9 years old, Group 10-11 years old, Group 12-13 years old. The dislocation of hip was classified by T?nnis classification system:gradeⅡ34 hips, gradeⅢ29 hips, gradeⅣ49 hips. Surgery was performed in all the patients. The procedures consisted of open reduction of the hip, capsulorraphy, shortening and derotational osteotomy of proxi?mal femur, and acetabular osteotomy which include Pemberton osteotomy (66 hips), Salter osteotomy (30 hips), Ganz osteotomy (3 hips), Triple osteotomy (5 hips) and Chiari osteotomy (8 hips). McKay and Severin modified criteria were used to assess the func?tion and radiographic results of the hip. Results The average follow?up was 2.3 years ranged from 1 to 7 years. According to McKay modified criteria at final follow?up, 75 hips (67%) had excellent (22 hips) and good (53 hips) clinical results, 32 hips (29%) were fair and 5 hips (4%) were poor. According to the Severin criteria, the outcomes of T?nnis grade Ⅳgroup was significantly worse than T?nnis gradeⅡ,Ⅲgroup. There is no significant differences between T?nnisⅡandⅢtype groups. If the patients were classified by age at time of operation, the function of group 8-9 years old was significantly better than others group according to the McKay criteria; the group 12-13 years old was significantly worse than others group according to Severin criteria. Conclu?sion Open reduction with proximal femoral osteotomy and acetabular osteotomy was an effective procedure for the treatment of developmental dislocation of the hip in children above 8 years old. The surgical results were related to the age at time of treatment and T?nnis classification system; low dislocation (T?nnis Ⅱ, Ⅲ) and young age (younger than 10 years old) had better function and radiographic results compared with high dislocation (T?nnisⅣ) and elder age group.

Objective Because of the major trauma from thoracotomy , postoperative pain may arouse patients'psychological and physiological stress response and hence affected the treatment outcome and functional recovery seriously .We retrospectively studied the correlation between the staging of pain and nursing interference to investigate the effect of nursing interference on the pain intensity after thoracic surgery . Methods Five hundred and eighty cases of patients surviving thoracotomy between December 2013 and March 2014 in Nanjing Jingling Hospital were reviewed .Correlations between comfortable nursing measures such as effective analgesia , postural care , catheter care , environmental interventions , psychological intervention and the standard assessment of pain were analysed according to postoperative pain stage . Results With comprehensive nursing interference , the highest pain score occurred in the first 24 hour (2.89 ±0.39).The score was reduced gradually to 2.25 ±0.90 in stage Ⅱ, 1.58 ±0.57 in stage Ⅲ and 1.06 ±0.24 in stage Ⅳrespectively . Conclusion Comprehensive nursing interference according to pain staging may relieve pain effectively after thoracotomy .

To develop the awareness of in student nurses during their clinical nursing practice for the prevention of legal disputes and protection of patients’ safety. Enough efforts should be made to strengthen legal education at the beginning, to enrich legal knowledge in the middle, and to stress nursing safety and related countermeasures towards the end of the clinical nursing practice. It is necessary to have student nurses under the supervision of the teachers make sure that they are aware of and abide by the law all the time.

Objective To investigate the causes and factors of hemoglobinuria in patients with thrombosis after AngioJet mechanical thrombectomy.Methods The clinical data of 16 patients with thrombosis treated by AngioJet thrombectomy system were retrospectively analyzed.Nine patients with hemoglobinuria during the procedure were included in group A,while 7 patients without hemoglobinuria in group B.The type of surgical procedure,time of intraoperative aspiration and the thrombus volume were compared between both groups.Results Nine (9/16,56.23 ％) of 16 patients were found hemoglobinuria during and after AngioJet mechanical thrombectomy.There were no statistically significant differences in surgical approaches (x2 =1.667,P=0.197),the time of intraoperative aspiration ([320.11±108.80]s vs [265.29±31.46]s,t=0.741,P=0.457),the thrombus volume (x2=0.442,P=0.506) between both groups.No renal function failure were noted directly relating to the use of the AngioJet thrombectomy device.Condusion There are many factors influenced the occurrence of hemoglobinuria in the patients after AngioJet thrombectomy.It can be reduced by using reasonable type of intraoperative aspiration,controled time of aspiration and active perioperative symptomatic treatment.

Fe3O4-grafted nitrogen-doped graphene (Fe3O4/N-G) nanomaterials were synthesized by chemical co-precipitation method, and its adsorption properties were discussed preliminarily.It was demonstrated that the adsorption of parachlormetaxylenol on Fe3O4/N-G was not limited to uniform monolayer adsorption and the adsorption kinetic followed the pseudo-second-order kinetic mode.Then, an ultrasound-assisted magnetic solid-phase extraction with Fe3O4/N-G as the magnetic adsorbent has been developed for the determination of four compounds including triclosan, chloroxylenol, hexachlorobenzene and 2,2′,4,4′,5,5′-hexachlorobiphenyl in environmental water samples, in combination with gas chromatography coupled to tandem mass spectrometry.Several factors related to extraction efficiencies, such as the amount of adsorbent, extraction time, sample pH and desorption conditions were investigated.The proposed preparation procedure was as follows: 6.0 mg of Fe3O4/N-G was dispersed into 100 mL of water sample under ultrasound.After 15 s, the Fe3O4/N-G carrying four compounds was separated from the water sample by an external magnetic field.Then, the targets were eluted from Fe3O4/N-G with 3 mL of ethanol and 2 mL of dichloromethane, sequentially.Finally, the eluent was dried under a mild stream of nitrogen and reconstituted with methanol and dichloromethane (1∶1, V/V) for the subsequent GC-MS/MS analysis.Under the optimized condition, an excellent linearity was observed in the range of 0.1-10 ng/L for the four compounds, with the correlation coefficients ranging from 0.9983 to 0.9999.The limits of detections (S/N=3) ranged from 0.05 to 0.6 ng/L and the limits of quantity (S/N=10) ranged from 0.2 to 2.4 ng/L.The mean recoveries at three spiked levels ranged from 68.2% to 99.6%.The relative standard deviations (RSDs) of intraday and interday were in the range of 3.3%-6.9% and 3.4%-9.4% (n=6), respectively.The proposed method was demonstrated to be simple and feasible for the trace analysis of antimicrobial agents and organochlorine contaminants in environmental water samples.
