AIM: To investigate the protective effect of onychin on the endothelial cells injured by oxidative stress. METHODS: The injured model was established by endothelial cells treated with menadione. The growth inhibitory rate of endothelial cell was determined by MTT assay; NO - 2/NO - 3 concentration in the medium was determined by nitrate reductase assay; eNOS and caveolin-1 protein levels were determined by Western blot. RESULTS: Onychin significantly decreased the growth inhibitory rate of endothelial cells injured by menadione, increased NO - 2/NO - 3 concentration in the medium and eNOS activity and up-regulated caveolin-1 expression. CONCLUSION: Onychin possesses a protective effect against endothelial cell injury induced by menadione via caveolin-1/eNOS pathway.

Objective To evaluate the effect of Ebselen on the ischemia-reperfusion injury (IRI) in rat lungs from non-heart-beating donors (NHBD).Methods Forty Sprague-Dawley rats were paired randomly divided into two groups:group Ⅰ,NHBD with 30 min of warm ischemia time (WIT); group Ⅱ,NHBD with 30 min of WIT and administration of Ebselen.The donor lungs remained ventilated at the room temperature for 30 min after asystolia and then flushed with LPD solution.The recipient rats underwent left lung transplantation.The recipients of group Ⅱ were administered with Ebselen (500 mg/kg body weight) one h before transplantation.Results All the recipients survived during the observation period.In the group Ⅱ,the MDA of the pulmonary tissue was 0.631 ± 0.23 nrmol/mg protein,and the polymorphonuclear neutrophils and the total protein of the bronchoalveolar lavage fluid were (78.4 ± 35.2) × 107/L and (0.41 ± 0.12) mg/ml respectively.The MPO was (25.09 ± 1.19) ％ and W/D was 0.359 ± 0.017.There was significant difference between group Ⅱ and group Ⅰ (all P＜ 0.05).Conclusion The administration of ebselen is an effective treatment to attenuate the acute injury resulted from the ischermia-reperfusion in the rat lungs from non-heart-beating donors.

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.
