Objective:To observe the protective effect of deproteinized extract of calf blood (DECB)on the ethanol-induced liver injury of the mice,and to preliminaryly discuss its mechanism. Methods:Sixty healthy ICR mice were divided into control group,model group,positive drug group,low,medium and high doses of DECB groups (n=10).By intragastric administration,the mice in control group were given 20 mL·kg-1 saline solution, the mice in low,medium and high doses of DECB groups were administrated with 0.125,0.250,0.500 g·kg -1 DECB,and the mice in positive drug group were administrated with 0.63 g·kg -1 Hugan Tablets;once a day for 30 d. 1 h after the last administration,except control group,the mice in other groups were administrated with one-time grant of 50% ethanol 14 mL·kg -1 ,and fasted for 16 h to establish the models of acute alcohol liver injury.The endurance alcohol time and drunk time of the mice were determined,the activities of aspartate aminotransferase (ALT)and alanine transaminase (AST)activity in serum of the mice were detected,the levels of triglyceride (TG),glutathione (GSH)and malonic dialdehyde (MDA)in liver tissue were determined,and the pathological changes of liver tissue were detected.Results:Compared with model group,the drunk symptoms of the mice in different doses of DECB groups were obviously reduced,the endurance time of the mice in high dose of DECB group and positive drug group was prolonged (P <0.05),and the drinking time was shortened (P <0.05);the ALT and AST activities in serum in mediun and high doses of DECB groups were significantly lower than those in model group (P <0.05).Compared with model group,the MDA and TG levels in liver tissue of the mice in medium and high doses of DECB groups and positive drug group were obviously reduced,and the GSH levels were increased (P <0.05);compared with model group,the pathological damages of liver tissue of the mice in high dose of DECB group caused by ethanol were significantly reduced.Conclusion:DECB can improve ethanol-induced liver injury which may be related to the inhibition of hepatic oxidative stress response.

BACKGROUND:Previous studies have indicated that resistin stimulates a large set of chemokines in chondrocytes that are known to be important in inflammatory joint lesions.
OBJECTIVE:To further investigate the mechanism of co-regulation roles of transcription and post-transcription in the up-regulation of two chemokine genes CCL3 and CCL4 in chondrocytes in response to resistin.
METHODS:Human chondrocytes, T/C-28a2 and ATDC5 cels were cultured. The function of resistin on the chemokine genes, and the expression of C/EBPβ, nuclear factor-κB isoforms and chondrogenic specific miRNAs were tested by qPCR. The co-regulation of C/EBPβ and nuclear factor-κB was investigated by nuclear factor-κB inhibitor (IKK-NBD) and C/EBPβ inhibitor (SB303580) treatments, and subcelular localization was detected with or without resistin stimulation.
RESULTS AND CONCLUSION:Resistin could increase the expression of chemokine genes independently. Chondrocytes reacted in a non-restrictedly cel-specific manner to resistin; C/EBPβ inhibitor, nuclear factor-κB and some chondrogenic specific miRNAs in a combinatorial manner regulated chemokine gene expression. The activity of C/EBPβ was augmented by a transient increase in activity of nuclear factor-κB, and both transcription factors acted independently on the chemokine genes, CCL3 and CCL4.

Objective To investigate the effect of selectively upward placement of acetabular implants on limb length and post?operative function of developmental dysplasia of the hip patients with shortened legs during total hip arthroplasty (THA). Methods Twenty?six cases of developmental dysplasia of the hip received THA between January 2008 and December 2013, in?cluding 12 cases of Crowe typeⅠ, 8 of Crowe typeⅡ, 6 of Crowe typeⅢ. There were 5 males and 21 females with an average age of 62.7 years (range, 36-80 years). The left hip was involved in 9 cases and the right hip in 17 cases. The preoperative mean Har?ris score was 42.30±12.84, and the preoperative mean WOMAC score was 59.08±13.84 at the last follow?up. The anteroposterior X?ray films and CT scan of the pelvis, anteroposterior and lateral X?ray films of the femur, and TraumaCad analysis were conducted routinely preoperation. More than 70%of the bone?implant interface was covered by appropriate upward distance of acetabular im?plant. Results The follow?up time ranged from 6 to 73 months (mean, 36 months). The Harris score improved to 91.18±7.09, and WOMAC score reduced to 9.85±3.75. According to postoperative measurement, affected limb had been lengthened by 0-5 mm in 8 cases, 6-10 mm in 5 cases, 11-15 mm in 5 cases,>15 mm in 7 cases, and shortening increased 1 mm in 1 case, but the average lengthening was 9.23±7.54 mm. The upward distance of acetabular implant was 0-5 mm in 10 cases, 6-10 mm in 7 cases and>10 mm in 9 cases. The average lengthening was 6.60±6.72 mm in patients having 0-5 mm upward distance, 11.90±5.64 mm in patients having 6-10 mm upward distance and 10.11 ± 9.35 mm in patients having>15 mm upward distance, showing no significant differ?ence. The leg length discrepancy was-3.70±6.43 mm in patients having 0-5 mm upward distance, 1.71±6.24 mm in patients having 6-10 mm upward distance and 0.56 ± 7.70 mm in patients having>15 mm upward distance, showing no significant difference. Con?clusion The limb length could be improved by selectively upward placement of acetabular implants in developmental dysplasia of the hip patients with anatomically abnormal acetabulum during THA, with reasonable preoperative design and corrective operation.
