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.

Gene chip is a research tool on molecular biology which can detect generous gene expression rapidly.The studies on gene chip of leiomyoma have revealed the changes of gene expression related to cell growth,proliferation,apoptosis,metabolism,angiogenesis,formation of extracellular matrix,cell differentiation and immunity.The article reviews the advance on gene chip of leiomyoma and approaches the pathogenesis of leiomyoma on molecular level.

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 investigate the effect of polygona-polysaccharose on experimental Alzheimer Disease(AD)mice and its possible mechanism. Methods Twenty-six amyloid precursor protein(APP)transgenic mice were randomly divided into high dosage group(HDG),low dosage group(LDG)and model group(MG)which consisted of 9,9 and 8 mice respectively.1 ml of 16%,4% polygona-polysaccharose solution and 1 ml of drinkable tap water were infused into the mouse stomach in HDG,LDG and MG respectively once a day for 45 days.Morris water maze was used to test the mice's proactive learning and memorizing ability.The morphology of cerebral hippocampus was observed by microscope.The content of amyloid-β-protein(Aβ)and the activity of choline acetyltransferase(ChAT)in the cerebral hippocampus were examined by immunochemical staining method. Results Comparisons among treatment groups(including HDG and LDG)and MG showed:(1)Escape delitescence was shortened[at seventh day:(26.0±9.4)s,(31.2±8.7)s and (39.3±10.9)s,P＜0.05];(2)The frequency of finding the hidden platform within 120 seconds was inereased(5.28±0.76)times,(3.00±0.77)times and(1.00±0.63)times,(P＜0.01);(3)The duration of swimming in objective quadrant(the forth quadrant)within 120 seconds was prolonged [(75.50±8.39)s,(51.39±11.9)s and(36.87±1.25)s,(P＜0.05)].HDG provided better results than those in LDG(all P＜0.05);(4)The activity of ChAT was enhanced and Aβ concentration was decreased for which results mice in HDG showed better than in LDG(all P＜0.05);(5)Morphological study in MG showed the sign of neuron apoptosis such as the reduced number of neuron.the shrinking neuron nuclei,the nucleic membrane being irregular and slightly thickened.However.the neuron in treatment groups were more in number,less transformed and more regularly distrIbuted. Conclusions Polygona-polysaccharose can reduce the accumulation of Aβ in the cerebral hippocampus of AD mice and enhance the activity of ChAT.It can significantly improve the learning and memorizing ability of AD mice and thus proves to be an effective experimental drug for treating AD.
