Objective To study the expression of multidrug resistance associated protein 1 (MRP1) and MRP2 in the peripheral blood mononuclear cells of children with intractable epilepsy (IE).Methods During Nov.2010 to Oct.2013,50 children with I E were collected as the experimental group,simultaneously 50 children with epilepsy controlled by the anti-epileptic drugs (AEDs) and 50 healthy children without epilepsy were collected as the control group from the outpatient or inpatient of Xuzhou Children's Hospital.The expressions of MRP1 and MRP2 in the peripheral blood mononuclear cells of children were detected by reverse transcriptase polymerase chain reaction and Western blot.Results 1.The mean relative expression of MRP1 and MRP2 mRNA in the peripheral blood mononuclear cells of children with IE (0.795 ± 0.042,0.804 ± 0.023) were higher than those in epilepsy controlled by AEDs (0.682 ± 0.030,0.675 ± 0.021) and healthy children without epilepsy (0.665 ± 0.031,0.654 ± 0.029) (all P ＜0.001).2.The mean relative expression of MRP1 and MRP2 protein in the peripheral blood mononuclear cells of children with IE (2.027 ±0.034,1.902 ±0.021) were higher than those in epilepsy controlled by AEDs(1.131 ±0.042,1.086 ± 0.027) and healthy children without epilepsy (1.093 ± 0.023,1.045 ± 0.018) (all P ＜ 0.001).3.There was no difference in the expression of MRP1,MRP2 mRNA and proteins between the children with epilepsy controlled by AEDs and healthy children without epilepsy (all P ＞ 0.05).Conclusions MRP1 and MRP2 over-expression in the peripheral blood mononuclear cells of children with IE may be associated with drug-resistance mechanism for medically intractable epilepsy.

Many studies have shown that chronic inflammation occurs in the brain of patients with Alzheimer's disease (AD). It is well known that long-term administration of non-steroidal anti-inflammatory drugs (NSAIDs) can alleviate the cognitive decline of AD patient and elderly. Several inflammatory cytokines produced in the metabolism of arachidonic acid (AA) are closely related to inflammatory diseases. Lipoxygenases (LOXs) and cyclooxygenases (COXs) play a crucial role in the AA network, the products eicosanoids have an important impact on the progression of AD. Although there are many arguments and conflicting evidence, currently LOXs and COXs are still the hot topics in the research on AD pathogenesis and drug development. Here, we review the progress in research on COXs and LOXs, including their actions on CNS and their association with AD, and explore the feasibility of LOXs and COXs as targets for the drugs to prevent and/or treat AD.

Objective To evaluate risk factors of in-hospital mortality during extracorporeal membrane oxygenation(ECMO) support for those with refractory cardiogenic shock after aortic surgery.Methods Retrospective analyses were conducted for 35 patients using ECMO after aortic surgery at Beijing Anzhen Hospital,Capital Medical University from September 2009 to March 2016.Demographic characteristics,diagnosis,ECMO related data,including ECMO indication,operation,clinical parameters before and 24 hours during ECMO were collected to set up a database.The patients were divided into survival group and non-survival group according to the prognosis.The risk factors of mortality in hospital after ECMO were analyzed by multivariate logistic regression analysis regression.Results There were 35 adult patients who had received ECMO support with 32 male and 3female.All patients received veno-arterial ECMO (V-A ECMO).ECMO was successfully weaned in 22 patients (62.9％),and 18 patients(51.4％) survived.Multivariate logistic regression analysis revealed that high lactic acid levels at 12 hours after ECMO(OR =1.445;95％ CI:1.026-2.034) and multiple organ dysfunction syndrome(MODS,OR =10.412;95％ CI:2.246-70.798)(P ＜ 0.05) were independent risk factors of in-hospital mortality in adult patients undergoing ECMO after aortic surgery.Conclusion High lactic acid levels at 12 hours after ECMO and MODS were very important factors of patients undergoing ECMO after aortic surgery.The proper identification and management shall improve the prognosis of patients.

Objective To compare the effect of diversification rehabilitation team mode on function in patients with cerebral infarction. Methods Sixty-six patients with cerebral infarction were divided into diversification rehabilitation team mode group (diversification group) and routine rehabilitation mode (routine group) according to the rehabililation method with 33 cases each. All patients of 2 groups were treated for 2 weeks. Evaluations were made before and after treatment. The simplified Fugl-Meyer motor function rating scale was used to evaluate motor function, modified Barthel index was used to evaluate activities of daily living, and MOS 36-item short form health survey was used to evaluate quality of life;and 0-100 digital simulation assessment was used to evaluate patient satisfaction after treatment. Results The simplified Fugl-Meyer motor function rating scale score, modified Barthel index score, MOS 36-item short form health survey score and patient satisfaction rate after treatment in diversification group were significantly better than those in routine group: (76 ± 4) scores vs. (63 ± 3) scores, (65 ± 3) scores vs. (52 ± 4 ) scores, (57 ± 7) scores vs. (44 ± 6) scores, (92 ± 5) scores vs. (77 ± 3) scores, and there were statistical differences (P<0.05). Conclusions Both kinds of rehabilitation model can promote functional recovery in patients with cerebral infarction, but diversification rehabilitation team model is better than conventional model.

Objective To investigate the difference of hypoglycemic and hypolipidemic effects of Coptis deltoidea (Coptis chinensis) and its processed products on T2DM rats. Methods Type 2 diabetes mellitus induced by high sugar, high fat diet and low dose of streptozotocin. C. deltoidea were processed with yellow wine, ginger, and evodia rutaecarpa, respectively. The effects of C. deltoidea on fasting blood glucose (FBG), fasting insulin (FINS), glycosylated serum protein (GSP), pancreatic pathology, serum triglyceride (TG), total cholesterol (TC) and lipoprotein (HDL-C or LDL-C) and key protein and gene expression of SCAP\SREBP-1c pathway in liver of model rats were investigated. Result C. deltoidea and its processed products reduced the FBG and GSP in T2DM rats. The wine products significantly reduced FBG and GSP in model rats (P < 0.01). The hypoglycemic range was better than raw and ginger products. At hypolipidemic aspect, C. deltoidea and its processed products decreased the content of TG, TC, and LDL-C (P < 0.05, 0.01), increased the content of HDL-C in serum (P < 0.05, 0.01), and down-regulated the protein and gene expression of SCAP/SREBP-1c in liver, the insulin target organ. However, wine and evodia products were better than crude drug or ginger products. Conclusion C. deltoidea processed by yellow wine, ginger and evodia rutaecarpa is traditional method to improve the disadvantages of C. deltoidea with bitter cold nature and not easy to take for a long time. However, different processing methods have different effects. Clinical medication should be combied withTCM syndrome differentiation and simple hypoglycemic effect of wine product is appropriate; while wine and evodia products were better in hypoglycemic and lipid regulation aspects.

Our goal was to establish two new predictive models of prostate cancer to determine whether to require a prostate biopsy when the prostate-specific antigen level is in the diagnostic gray zone. A retrospective analysis of 197 patients undergoing prostate biopsy with prostate-specific antigens between 4 and 10 ng ml-1 was conducted. Of these, 47 patients were confirmed to have cancer, while the remaining 150 patients were diagnosed with benign prostate disease after examining biopsy pathology. Two multivariate logistic regression models were established including age, prostate volumes, free/total prostate-specific antigen ratio, and prostate-specific antigen density using SPSS 19.0 to obtain the predicted probability and Logit P, and then, two receiver operating characteristic (ROC) curves were drawn to obtain the best cutoff value for prostate biopsy: one for the group of all the prostate cancers and one for the group of clinically significant prostate cancers. The best cutoff value for prostate biopsy was 0.25 from the multivariate logistic regression ROC curve model of all the prostate cancers, which gave a sensitivity of 75.4% and a specificity of 75.8%. The best cutoff value for prostate biopsy was 0.20 from the multivariate logistic regression model of clinically significant prostate cancers, which gave a sensitivity of 76.7% and a specificity of 80.1%. We identified the best cutoff values for prostate biopsy (0.25 for all prostate cancers and 0.20 for clinically significant prostate cancers) to determine whether to require prostate biopsy when the PSA level is in the diagnostic gray zone.

Although current synthetic anti-gout drugs have significant therapeutic effects in reducing serum uric acid levels, they have serious side effects such as allergic reactions and liver and kidney damage. Natural products with a wide range of uric acid-lowering and high safety have played a critical role in anti-gout drug discovery and development. This paper reviews the natural products with uric acid-lowering or anti-gout pharmacological effects and the investigation on their mechanisms of action, to provide information for drug discovery and development.

Objective To compare the effects of short- term high- intensity interval training (HIT) and moderate continuous training (MCT) on inflammatory mediators for healthy young males. Methods 19 healthy young male volunteers were randomized into HIT group (n=6), MCT group (n=7) and no training control (CON, n=6) group. The groups of HIT and MCT accepted treadmill exercise once per 2 days to 6 times (2 weeks), and the CON group did not accepted treadmill exercise. The levels of high-sensitive C-reactive protein (hs-CRP), interleukin (IL) -1α, IL-6 and tumor necrosis factor α (TNF-α) were detected 3 days before exercise, immediately after the first exercise, 3 days after the course. Results There was no difference among groups in the level of hs-CRP, IL-1α, IL-6 and TNF-α in all the time (P>0.05). The concentration of IL-1α increased in the MCT group after the first exercise (P<0.01), and also the concentration of IL-6 in the CON group after the course (P<0.05). Conclusion It needs further srudy for the significance of HIT and MCT in the levels of inflammatory media.
