ObjectiveTo investigate the efficacy and safety of the self-expandable metal stent for treatment of gastric outlet and duodenal obstruction.MethodsData of 24 patients with symptomatic gastric outlet and duodenal obstruction diagnosed from January 2005 to February 2011 were retrospectively studied.All patients were measured by gastric outlet obstruction scoring system ( GOOSS ) before and one week after the placement of self-expandable metal stent.ResultsStent placement was succeeded in all patients with a mean operation time of 25.90 ± 11.03 min.Twenty patients (83.3％) were able to intake liquid food after the procedure.The GOOSS (P50 =0) before and after stent placement were 0.14 (P50 =0) and 1.42( P50 =2),respectively,with significant difference (P ＜0.01 ).Minor digestive bleeding occurred in 3 patients,but no severe complications including perforation or aspiration were observed.ConclusionPlacement of a self-expandable metal stent in patients with gastric outlet or duodenal obstruction is safe and effective for resolving obstructive symptoms.

[ABSTRACT]OBJECTIVETo explore the role and mechanism of IL-13 in regulating the differentiation of ciliated cells on cultured human primary nasal epithelial cells.METHODSHuman nasal epithelial cells were cultured in vitro and treated by IL-13, the differentiation of epithelial cells was observed by western blot detection ofβ-tubulinⅣ and ELISA detection of MUC5AC; the percentage of ciliated and goblet cells was quantified by cytospin followed by immunohistochemical staining; the expression level of central ciliary genes was detected by real-time PCR.RESULTSCompared with control group, IL-13 treatment for 14 day significantly decreased the percentage of ciliated cells and expression ofβ-tubulinⅣ, additionally increased the goblet cells and the secretion of MUC5AC; IL-13 treatment significantly reduced the expression of ciliary key transcription factors such as FOXJ1, RFX2 and RFX3, as well as basal body biogenesis genes like CCNO and CETN2.CONCLUSIONIL-13 inhibits the differentiation of human nasal ciliated epithelial cells, which may be by down-regulating the expression of ciliary key transcription factors and basal body biogenesis proteins.

Objective To study the effect of the genetic factors on the occurrence and development of type 2 diabetes mellitus(T2DM) and its general genetic pattern.Methods 21 T2DM cases,as proband,were investigated for T2DM genealogical tree.The heritability of T2DM was estimated by Falconer method.T2DM segregation rate and genetic pattern were evaluated with Penrose's method,Li-Mantel-Gart method and the threshold value model method of Jiang San-Duo.Results The prevalent rate of T2DM in first-degree relatives was 7.6%,which was higher than that in general population.The heritability of T2DM was 46.8%.The s/q score was 3.312 with Penrose's method,which was near to 1/q1/2.The segregation rate P was 0.131,which was lower than 0.25.The theoretical prevalent rate in first relatives was 8.0%,while the investigated prevalent rate was 7.6%.Conclusion There is an obvious heritable trend in T2DM.It is fit to the multi-factorial inheritance pattern but the mono-gene heritability model.

Biomass is a renewable resource, which can be transformed into useful chemical products. The effects of dilute hydrochloric acid on the hydrolysis of steam explosion pretreatment of corn straw were studied. This article developed the application research of ergosterol using corn straw hydrolysates as fer- mentation substrates. The results showed that when corn straw was hydrolyzed with 1.5% hydrochloric acid, temperature at 90?C, hydrolysis for 3 h and the corresponding solid to liquid ratio at 10%, the reducing sugar content can reached up to 53.3% and cellulose conversion efficiency was 79%. The optimal fermental pa- rameters were as follows: 6.0 oBx of corn straw hydrolysates, corn concentration steep water at 4%, pH 7.5, 10% of inoculation, 28?C cultivated for 32 h. Under these conditions, the yeast biomass up to 8.5 g/L and the ergosterol content up to 2.35%. The infrared spectrometer and the X-ray diffract meter used to characterize of crystallite structure.

This study is to investigate the influence and mechanism of action of asymmetrical dimethylarginine (ADMA) and the induced oxidative stress level on Alzheimer's disease (AD) incidence. ADMA concentration, nitric oxide, Abeta(40)/Abeta(42) ratio, inducible NO synthase (iNOS) activity and the concentrations of the induced free radicals including malondialdehyde (MDA), 3-nitrotyrosine (3-NT) and peroxynitrite (ONOO-) in the cerebrospinal fluid (CSF) from 34 neurologically normal controls and 37 AD patients were quantitatively determined and statistically compared. The results showed that the ADMA concentration significantly decreased in AD patients, and it showed negative correlation with the NO, iNOS activity, and showed positive correlation with MMSE score. ADMA concentration was negatively correlated with Abeta(40)/Abeta(42) ratio (P<0.01) with the observation that Abeta(40)/Abeta(42) ratio increased while ADMA level decreased in CSF in AD patients. The concentration levels of MDA, 3-NT and ROS significantly increased compared with the control with all the P values less than 0.05. These findings suggested that the ADMA disorder and the oxidative damage effect of the induced free radicals in CSF of AD patients are an important mechanism of AD incidence, and their joint regulation may provide new idea for the prevention and clinical treatment of AD.

Objective To study the methods and effects by using thrombolytic catheter in interventional treatment for patients with acute lower limb arterial thrombosis or embolism. Methods One hundred and twelve patients suffered acute lower limb arterial thrombosis or embolism. There were 85 cases of acute lower limb arterial embolism induced by atrial fibrillation in coronary or rheumatic heart disease,other 27 cases of arterial thrombosis caused by different reasons. Interventional treatment by inlying thrombolytic catheter was applied and continuous perfusion was received locally in all patients. Results Complete recanalization was got in 77 cases (68.8%) of 112 cases. Partial re canalization was got in 23 cases (20.5%), and ischemia limbs were saved in spite of chronic limb ischemia(chronic spasmodic limb) occurring in the later follow-up. Nine cases (8.0%) were amputated as a result of irreversible limbs necrosis, 3 cases (2.7%) died from acute renal failure resulting from reperfusion injury or recurrent cerebral embolism.Conclusion Interventional treatment by inlying thrombolytic catheter is a safe and effective method with lower amputation rate for acute lower limb arterial thrombosis or embolism in patients.

Objective To explore the significance of changes of matrix metalloproteinase-9 (MMP-9),interleukin-6 (IL-6),and tumor necrosis factor-alpha (TNF-oα) protein level in the cerebrospinal fluid (CSF) of children with viral encephalitis (VE).Methods The concentration of neuron-specific enolase (NSE),structural proteins 100B (S100B),and MMP-9,IL-6,TNF-α in the CSF of VE children were detected by an enzyme linked immunosorbent assay,and the correlations of them were analyzed.Results NSE,S100B,MMP-9,IL-6,TNF-α protein expression could be found significantly higher than those in the control group,and there were significant differences according to statistics expression trends(all P ＜0.05).The NSE protein expression was significantly positive related with S100B in the VE group (r =0.467,P =0.009),and the concentration was markedly negative related with the duration of viral encephalitis (r =-0.472,P =0.008).MMP-9,IL-6 protein expression were significantly positive related with NSE,S100B respectively (r =0.698,P =0.00 ; r =0.559,P =0.00 ; r =0.812,P =0.00 ; r =0.664,P =0.00).TNF-α protein expression was positive related with CSF S100B(r =0.363,P =0.049),but there was no correlation between TNF-α and NSE (r =0.245,P =0.193).Conclusions The neurons and the neuroglial cells are damaged in the viral encephalitis children.MMP-9,IL-6,TNF-α protein may participate in the pathological damage process of nerve cells in VE children in different degrees.

Objective To investigate the correlations between plasma levels of carnitine(CT),free fat acid(FFA) and insulin resisitance in children with simple obesity.Methods Fifty-six children diagnosed with simple obesity were enrolled as study group(obesity group),36 healthy children as control group.The concentration of plasma level of insulin was measured by radioimmunoassay(RIA),CT was measured by high performance liquid chromatography(HPLC),FFA and triglyceride(TG) were measured by enzymatic-colorimetric assay.Body mass index(BMI) and waist to hip ratio(WHR) were caculated.Insulin sensitivity index (InSI) and insulin resistance index (InRI) were cacula-ted by homeostasis model assessment of insulin resistance (HOMA-IR).SPSS 13.0 software was used to analyze the data.Results The concentration of CT in plasma was (43.67?12.75) ?mol/L in obesity group,(58.31?21.25) ?mol/L in control group,respectively.There was a significant difference between 2 groups (t=2.566 P

The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P < 0.000 010 and electrocardiogram curative effect (OR = 2.21; 95% CI; [1.83, 2.68]; P < 0.000 010. Funnel figure seemed that there was publication bias. The current limited evidence showed that when compared with the control group, treatment group was superior in improving patients with angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.
