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.
