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 To analyze the clinicopathological characteristics and the prognostic survival factors of young patients who have undergone hepatectomy for primary hepatic carcinoma.Methods Clinicopathological da-ta and treatment outcomes in 79 young (≤40 years old)and 67 elderly (≥65 years old)patients who underwent hep-atectomy for primary hepatic carcinoma between 2008 and 2012 were retrospectively collected and compared using various parameters.Then the survival rate and prognostic factors of the younger patients were analyzed using Kap-lan-Meier and COX multivariate proportional hazards model.Results The positive rate of HBs-antigen and alpha-fetoprotein level were significantly higher in the younger patients than in the elderly patients (P<0.05).However, the positive rate of Anti-HCV-Ab was markedly lower in the younger patients (P<0 .0 5 ).The two groups did not significantly differ in gender,clinical symptoms,intraoperative parameters or pathological features (P>0.05).The overall survival rate was similar between the two groups.COX multivariate proportional hazards model analysis showed that the independent prognostic factors of overall survival were pre-operative albumin level <3 5 g/L and maximum tumor diameter ≥5 cm.Conclusion Hepatectomy is a safe and feasible treatment for young and elderly patients with primary hepatic carcinoma.The independent prognostic factors of survival for young patients are pre-operative albumin level <3 5 g/L and the maximum tumor diameter ≥5 cm.

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.

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.
