Objective To investigate the expression of CD14/CD16 by monocytes and the anti-inflammatory effects of hypertonic saline plus dextran (HSD) in adult blunt trauma patients in hemonhagic shock. Method A total of 30 adult patients were eligible for inclusion in the study if they sustained blunt trauma from March to October 2007 and had at least one recorded episode of hypotension (systolic blood pressure ≤ 90 mm Hg) with clear evidence of blood loss (external or internal including the thorax, abdomen or retroperitoneum). Patients were excluded if they refused to participate, were admitted ≥ 6 hours after injury, were pregnant, or had chronic disease. The enrolled patients were randomly divided in a double-blinded manner into an HSD group which was administered 7.5% Nad plus 6% dextran - 70, and a control group which was administered 0.9% NaCl. A single 250 ml dose of either HSD or NaO was immediately administered to the patients in each of the two groups while they were in the emergency room. The primary outcomes were to measure the changes in CD4/CD16 expression by monocytes and the levels of anti-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin (IL)-lra and IL-10. Patient demographics, fluid requirements, organ dysfunction, infection and death were recorded. Results A total of 28 patients were enrolled with no significant differences in their clinical measurements. Hyperosmolarity was modest and transient. HSD altered the shock-induced monocyte redistribution pattern by reducing the drop in the "classic" CD14 ++ subset and remarkably affecting the expansion of the "pro-inflammatory" CD14+CD16+ subsets. In parallel, HSD significamly reduced pro-inflammatory TNF-α production while increasing anti-inflammatory IL-lra and IL-10 production. Conclusions This human trial demonstrates that HSD has anti-inflammatory and immunologic properties for trauma patients in hemorrhagic shock. HSD exerts profound immunomodulatory effects, promoting more balanced pro-/anti-inflammatory responses and reducing post-traumatic complications. Therefore, it could be useful in attenuating post-trauma multiorgan dysfunction (MOD).

Objective To explore the expression of PRR11(Proline-rich protein 11) in human osteosarcoma and investigate the effect of PRR11 on the proliferation of human osteosarcoma cells.Methods Immunohistochemical staining was applied to detect the PRR11 expression in 75 cases of osteosarcoma and corresponding normal tissues.Western blotting was used to examine PRR11 protein expression levels in osteosarcoma cell lines.We used siRNA to knock down the expression of PRR11 and tested the effects of PRR11 down-regulation on the proliferation in SaOS2 cells.Results PRR11 was overexpressed in osteosarcoma specimens compared to their paired normal tissues,the over expression rate of PRR11 in osteosarcoma and corresponding paracancerous tissues were 76％(57/75) and 9.33％(7/75) with statistical difference(P<0.05).The high expression of PRR11 was correlated with tumor pathological grade and lymphatic metastasis(P<0.05).PRR11 was expressed in 4 osteosarcoma cell lines which were SaOS2,143B,U2OS and MG63 respectively,the expression was highest in SaOS2 cells.Silencing PRR11 inhibited cell growth as compared with control cells(P<0.05).Conclusion PRR11 is overexpression in human osteosarcoma and promotes its progression by enhancing proliferation.The increased expression of PRR11 in osteosarcoma is a new target for treatment and early diagnosis of human osteosarcoma patients.

AlM: To compare the different formulas in intraocular lens(lOL) power calculations on high myopia after LASlK with cataract patients who received the phacoemulsification and intraocular lens implantation ( Phaco+lOL) .
METHODS:This was a retrospective study. Data from 102 eyes of 61 cataract patients with high myopia, who received Phaco+lOL after LASlK, were collected. Patients were divided into three groups by formulas in lOL power calculations before surgery: Holladay group ( 11 cases, 21 eyes), Haigis-L group (30 cases, 47 eyes) and SRK-T group (20 cases, 34 eyes). The ratios of equivalent lOL power after LASlK were predicted and the accuracy of their predictions were compared 3mo after surgery. lt was an index of reliability of the formulas outcomes.
RESULTS:The ratios of equivalent lOL power after LASlK using the Holladay, Haigis-L and SRK-T formulas were 0. 86 ± 0. 41D, 0. 43 ± 0. 30D and 1. 27 ± 0. 58D, respectively . There was no significant difference between Holladay group and SRK-T group ( t=-0. 271, P=0. 625>0. 05 ). However, significant difference was found between Haigis-L group and Holladay group ( t=2. 249, P=0.047<0. 05), Haigis-L group and SRK-T group (t=6. 012, P=0. 031<0. 05).
CONCLUSlON:The Haigis-L formula is more accurate than the SRK-T and Holladay formulas in predicting lOL power for cataract patients with high myopia after LASlK.
