Objective To investigate the physical and mechanical properties of home-made bone cement mixed with different antibiotics.Methods The specimens of bone cement each of 40g were divid-ed in to6groups depending on mixed antibiotics,groupⅠmixed with1g gentamicin,groupⅡwith2g gen tam icin,groupⅢwith1g cephradine,groupⅣwith1.5g cefuroxine,groupⅤwith1g ceftriaxone and groupⅥwith out any antibiotics served as control.The dough time,compressing depth,compressive strength,bending strength and bending elastic modulus were measured respectively,elution examination of antibiotics from bone ce ment was performed by chromatography.Results The dough time and compress-ing depth of the groups were better than that of ISO5833standard,and there was no significant difference a-mong the groups.The com pressive strength and bending strength of the groupⅡwere lower than that ISO5833standard,but there was no significant difference among the groups by analysis of variance.The bending elastic modulus of the groupⅡwas lower than the control group and other groups(P

Objective To collect the main contents of research in critical care medicine in foreign countries with the purpose of providing references for domestic research. Methods A two-way clustering analysis of foreign literature in PubMed concerning critical care medicine was conducted from 2004 to 2015 in this study, and the subjects of greatest interest were collected through the information visualization analysis pathway. Results Eight areas of most popular interest critical care medicine from January 1st, 2004 to November 8th, 2015 were found: blood sugar control in intensive care unit (ICU), acute kidney injury (AKI) and renal replacement therapy (RRT), nutritional support, the impact of ICU practice on reducing mortality, the assessment of critical patients, study of antibiotic resistance, the assessment of the life quality of critically ill patients, and home care and the rehabilitation of critically ill patients. According to the related literature, research in the field of critical care medicine has been growing steadily. USA, Japan, and Europe are the most developed countries or area in the field of critical care medicine. The four major research networks concerning research in critical care medicine were found: the control of blood glucose, monitor of circulatory function, nutritional support, and studies on AKI. Conclusion The most popular topics in research concerning critical care medicine research from 2004 to 2015 were blood glucose control, monitoring of circulatory function, nutritional support and AKI.

Objective To investigate the protein and gene expression of bcl-2, bcl-6 in diffuse large B-cell lymphoma (DLBCL). Methods 73 cases of DLBCL were selected for study using the Envision immunohistochemistry method with a panel of antibodies CD3, CD10, CD20, bcl-6, bcl-2, MUM-1. The bcl-2gene expression in 57 of 73 cases with chromosome translocation t (14; 18), breakage and amplification of 3q27 chromosome in 54 of 73 cases were detected by fluorescence in situ hybridization (FISH) method. Results The percentages of tumor cells expressing CD10, bcl-6, MUM-1, bcl-2 were separately 15.1%, 38.4 %, 71.2 %, 79.2 %. t (14;18) chromosomes were detected in 16 of 57 cases (28.1%). The expression of bcl-2 protein have significantly correlated with immunophenotype subtype (P=0.035), and t (14;18) was significantly correlated with the prognosis (P=0.045). There were no association between the expression of bcl-2 protein and t (14;18)(P=0.710). 11 of 54 cases were presented with 3q27 chromosomal breakage (20.4 %), and 14 cases were chromosomal amplification (25.9 %). The prognosis of cases with positive bcl-6 protein was better than that with negative protein obviously. There was no relationship between bcl-6 and 3q27 chromosomal breakage or amplification (P=1.000). Conclusion The expression of bcl-2, bcl-6 protein and gene were different events and had the different significance on DLBCL. The expression of bcl-2 protein was a prognostic marker correlated with immunophenotype subtype, and GCB type with the positive expression of bcl-2 protein had the poor prognosis. Conversely, t(14;18) was an independent event for the prognosis, and the positive expression have the poor prognosis. Patients who require the target therapy should be detected for the t(14;18). The expression of bcl-6 protein was beneficial to the judgment of DLBCL prognosis, it could be an independent factor of the prognosis. 3q27 chromosomal breakage may be a hint to the poor prognosis.

Objective To establish the optimal ethanol extraction technology of Qingshen Granule. Methods The total content of emodin, chrysophanol and physcion, the content of tanshinoneⅡA and dry extact rate was set as indexes, orthogonal test was adopted to optimize the technology. Results The optimum extraction conditions were as follows:8 times of 80%alcohol, refluxing 3 times and 2 hours for each time. Conclusion The optimum technology of Qingshen Granule is simple, stable and effective.

To simultaneously determine the contents and explore the pharmacokinetics of ferulic acid and paeoniflorin by high performance liquid chromatography (HPLC) after oral administration of Modified Xiao-yao Decoction (MXYD), a compound of traditional Chinese herbal medicine.

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).
