ObjectiveTo study the effect of behavior training on the expression of neural growth factor(NGF) in the dentate gyrus(DG) in rats with left lateral hippocampal infarction.Methods102 SD rats were randomized into fore-training,3 d,7 d,14 d,21 d,28 d,35 d,42 d,49 d training groups,fore-immobilization, 3 d、7 d,14 d,21 d,28 d,35 d,42 d,49 d immobilization groups and control group.Behavior training and immobilization were performed at 1st day after the infarction.Immunohistochemistry was used to detect the expression of NGF in the DG at different points of time.ResultsThe expression of NGF is certain in the normal DG of rats.The expression of NGF increased after infarction.However,the expression of NGF had obviously increased in fore-training groups compared with that in fore-immobilization groups.ConclusionBehavior training can accelerate the expression of NGF in the DG of rats with left hippocampal infarction.

Objective To study the incidence and risk factors of infection caused by methicillinresistant staphylococcus aureus (MRSA) with a targeted surveillance at intensive care unit (ICU) acquired MRSA infection in Tianjin area.Methods A prospective multi-center observational analysis of consecutive patients admitted to 15 adult ICUs from March 1,2012 through March 31,2014 was carried out.The ICUs were divided into four groups according to the type of the ICU.All of the patients were cared for with routine MRSA surveillance.A number of risk markers and prognostic factors were recorded.The risk factors contributing to ICU acquired MRSA were evaluated using a logistic regression model.Comparison of survival between groups was analyzed with Kaplan-Meier method.Results A total of 1 787 patients were enrolled,and 144 cases of them were MRSA infections.The patients with MRSA infection were significantly older than those with non-MRSA infection (P =0.043),length of ICU stay,length of antimicrobial therapy,the history of repeated administration of antibiotics in recent days,history of operation in the past five years,history of MRSA infection or colonization,frequent application of and the overall length of time for mechanical ventilation and central venous catheter and catheter-associated infection were significantly higher than those with non-MRSA infection.The survival rate of patients with non-MRSA infection were higher than those with MRSA infection (x2 =9.23,P =0.004).The rate of MRSA infection and MRSA colonization in 2013 were significantly lower than that in 2012,because the rate of hand hygiene rule execution and bacterial clearance rate were significantly higher in 2013.Multivariate Logistic regression analysis demonstrated that advanced age (OR =1.05,95％ CI:1.009-1.086),length of ICU stay (OR =1.05,95％ CI:1.01-1.08),history of MRSA infection or colonization (OR =1.33,95％ CI:1.82 -3.27),glucocorticoid therapy (OR =2.85,95％ CI:1.18-6.91),antacid medicine (OR =4.92,95％ CI:1.18-20.58),history of recent or repeated application of antibiotics (OR =3.26,95％ CI:1.06-4.59) catheter-associated infections (OR =2.22,95％ CI:1.08-4.59) were associated with ICU acquired MRSA infections.Conclusions Performing the rule of hand hygiene strictly as well as strengthening prevention and control of MRSA infections can effectively reduce the incidence of ICU acquired MRSA infections.The advanced age,length of ICU stay,history of MRSA infection or colonization,glucocorticoid therapy,antacids medicine,history of recent or repeated application of antibiotics,catheterassociated infections were independent risk factors of ICU acquired MRSA infections.

AIM:To be one of the primary cause injury to multiple sites of ocular of glaucoma which affects over 70 million people worldwide. We applied data mining techniques, linear and the matrix operations, efficiently calculated the network and estimated the possible function of the“node” genes of the retina and optic of glaucoma, in order to provide new thought and method on the pathogenesis of glaucoma.
METHODS: The data in this study is from Gene Expression Omnibus ( GEO ) which belong to Nation Center for Biotechnology Information ( NCBI) , the quality of the raw data CEL files was processed and analyzed by the Expression software which belong to Affymetrix Inc. , Santa Clare, CA, USA. Significant analysis method ( SAM) which base on the T test was used to identified the significant genes. Based on GRNInfer and Gvedit soft we set up gene networks of optic and retina of mice and further more enriched analysis which based on DAVID and MAS3. 0 online software were processed.
RESULTS:The analysis between the group of the optic nerve heads and retinas in different stage of glaucoma showed that the amount of significant different expressed genes in the optic never head group increased significantly comparing with the group of retina in the early stage of glaucoma, the analysis of the genes network construction show that:the node genes of optic nerve heads included Unc13c、Kif5a、TRPM1、PANX; and the node genes of retina include POU4F1, NEFL, BC03870, CALB2. Metabolic pathways enrichment analysis which based on MAS3. 0 online platform show that there was mainly the amyotrophic lateral sclerosis, tyrosine metabolism, melanogenesis, Nitrogen metabolism, Gap junction, Leukocyte transendothelial migration metabolism pathway enriched out in optic nerve head; and there was mainly amyotrophic lateral sclerosis, neurodegenerative disorders, prostate cancer, leukocyte transendothelial migration metabolism pathway enriched out in retina.
CONCLUSION:By understanding bioinformatics result, it seems optic were more sensitive than the retina to high intraocular pressure, and weather high expression of TYrp1 gene can be as a sensitive diagnostic item require more evidence back up. Functional enrich analysis of node gene showed that cytoskeleton reconstructed, molecular motor and nutrients transport function improve in optic; and in retina, the most prominent finding in retina was enrichment function modules were focus on regeneration, repairing and differentiation of cells, which remind that we should reinforce research on reparation of retina of primary glaucoma. Metabolic pathways enrichment analysis show that inflammatory response plays prominent place in optic and retina of primary glaucoma, because of the optic narrow and crowed anatomic shape, nutrient metabolism and substances transfer enrichment modules play an important role in optics of primary glaucoma.

The aim of this thesis is to prepare etoposide submicro-emulsion (ESE) for intravenous injection and investigate its characteristics in vitro and in vivo. High-pressure homogenization was used to prepare ESE, using 10% (w/w) soybean oil and 10% (w/w) medium-chain triglyceride as mixed oil phase, and 1.8% (w/w) fabaceous lecithin as emulsifier. The pH was adjusted to 5.5 with 0.1 mol x L(-1) NaOH to keep the most stability of ESE. The particle size distribution and zeta potential were measured using photon correlation spectroscopy. Ultrafiltration was used to estimate the relative percentages of etoposide in each phase. Long-term storage test and accelerated isothermal test-Weibull distribution method were used to estimate the physical and chemical stability of ESE. Plasma pharmacokinetics in rats was monitored by high performance liquid chromatography by comparison with etoposide nonaqueous solution at the same time. The mean particle size, zeta potential and entrapment efficiency of ESE were (189.9 +/- 54.6) nm, - 32.6 mV and 91.7%, respectively. The emulsion was stable during 9 month storage at 4 degrees C. The shelf life (T0.9) of etoposide in lipid emulsion was estimated to be about 665 days at 4 degrees C. The drug concentration-time curves of ESE and solution were similar and could be described by two compartment model. The area under the curve of concentration versus time from zero to the last time point and the mean residence time of ESE and solution were (18.30 +/- 8.74) and (19.32 +/- 6.45) microg x h x mL(-1), and (1.46 +/- 0.32) and (1.71 +/- 0.52) h, respectively. Etoposide was incorporated in submicro-emulsion to improve its physical and chemical stability without addition of organic solvents with insignificant different characteristics in vivo when compared with solution.

Objective To compare the treatment effects between lymphatic chemotherapy and regional extended release chemotherapy (RERC) for rectal cancer lymph node metastasis. Methods The lymph nodes at or beside colon (first station), beside (second station) and at the root of mesentery blood vessel (third station) of the patients with rectal cancer in control group (20 cases), lymphatic chemotherapy group (20 cases) and RERC group (20 cases) were removed to compare proliferation index (PI), apoptotic index (AI) and AL/PI of cancer cells in the lymph nodes. Results The PI, AI, and AI/PI of cancer cells in correspondent lymph nodes were not statistically different between lymphatic chemotherapy group and the other 2 groups (F=4.973-7.394, 5.372-8.694, 4.527-5.436, P<0.05; t=3.128-7.688, 3.388-9.615, 6.518-13.180, P<0.05). The PI, AI, and AI/PI of cancer cells in the first and second station lymph nodes in RERC group were significantly different from those in control group (t=5.103, 4.927; 6.938, 6.450; 8.839, 9.021; P<0.05), and from those in the third station lymph nodes in RERC group (F=6.572, 8.964, 5.845, P<0.05; t=3.505, 3.353; 5.397, 4.701; 9.039, 8.629; P<0.05). Sorted by the treatment effects for cancer cells in lymph nodes, the first is each station of the lymphatic chemotherapy group, followed by the first and second station of the RERC group, and then the third station of the RERC group which was almost equal to any station of the control group. Conclusion Lymphatic chemotherapy is better than RERC in the treatment of rectal lymph node metastasis in the aspect of scale and degree.
