Objective To describe the factors influencing medication compliance of patients with ulcerative colitis (UC) and provide a reference for health care workers developing effective response plans.Methods In-depth interview was conducted to 10 UC patients and the interview results were analyzed by phenomenology research method.Results There were five factors influence medication compliance of UC patients including drug affect,economic burden,living events,follow-up appointment and stigma.Conclusions The medication compliance of UC patients is mainly related to patients lacking of drugs knowledge,heavy burden on drugs cost and shortage of social support etc.The health education and medication supervision on UC patients should be strengthened and the social health insurance system on UC needed to be improved.

Objective To analyze the predictive factors of fever after percutaneous renal stone surgery,and to provide reference for clinical treatment.Methods A total of 147 patients underwent percutaneous nephrolithotomy in after operation was chosen in the Department of Urology in our hospital from January 2014 to January 2016.According to the existence of fever,patients were divided into fever (n =25,heating rate 17.0％) and control (n =122) groups.Preoperative information were collected,including age,gender,preoperative serum creatinine,stone size and shape,the involvement of calyceal number,water,urine culture results,operative time,blood loss,intraoperative perfusion volume,pyonephrosis,puncture channel length,hospitalization time and other information including intraoperative,postoperative information including fever,and postoperative renal fistula complications if there is information.SPSS 18.0 was used for statistical analysis.Results The fever group stone surface area,CT value affected calyx number,stone shape,stone properties,the involvement of calyceal number,degree of hydronephrosis,operative time,intraoperative blood loss,intraoperative perfusion,hospitalization time,and renal fistula complication rates were higher than the control group (P ＜ 0.05).There were no significant differences between two groups (P ＞0.05).The results of Logistic regression analysis found that the stone surface area (OR =5.19),stone,stone shape (OR =7.86) properties (OR =3.87),operation time (OR =5.68),intraoperative perfusion (OR =5.24),and renal fistula complications (OR =2.65) for the influence factors of fever.Conclusions The stone surface area is large,stone nature infection stones,stone shape for staghorn calculi,longer operation time,and intraoperative perfusion of large renal fistula complications were more prone to postoperative fever in postoperative.

Objective:To observe the effect of Radix Paeoniae Bubra(RPB)on NADPH oxidase p22phox,monocyte chemotactic protein-1(MCP-1)mRNA expression and neointimal hyperplasia after carotid artery balloon injury in cholesterol-fed rabbits.Methods:The rabbit model of carotid balloon injury was established adopting Clowes method,and treated with extract of RPB.Component of neointima and expression of proliferating cell nuclear antigen(PCNA)and macrophage was determined by immunochemical stain.The collagen of typeⅠwas detected by special staining for blood vessels and the area of neointima was measured by image assay system.Expression of NADPH oxidase p22phox mRNA,MCP-1 mRNA was detected by in situ hybridization and transcription-polymerase chain reaction.Results:RPB can attenuate the neointima area and proliferation of collagen typeⅠinduced by balloon-injury,remarkable prevent the formation of restenosi,and down-regulate expression of NADPH oxidase p22 and MCP-1mRNA significantly and decrease the degree of macrophages infiltration especially in vessel wall of injuring carotid artery.Conclusions:RPB inhibited NADPH oxidase P22Phox and MCP-1 mRNA expression,and modestly reduced neointimal hyperplasia,which might be partly attributed to its antioxidant and inflammatory effects.

Objective To explore an algorithm to define the threshold value for tumor contouring on 18F-fluorodexyglucose (FDG) PET imaging. Methods A National Electrical Manufacturing Association (NEMA)NU 2 1994 PET phantom with 5 spheres of different diameters were filled with 18F-FDG. Seven different sphere-to-background ratios were obtained and the phantom was scanned by Discovery LS 4. For each sphere-to-background ratio, the maximum standardized uptake value ( SUVmax ) of each sphere, the SUV of the border of each sphere ( SUVborder ), the mean SUV of a 1 cm region of background (SUVbg) and the diameter (D) of each sphere were measured. SPSS 13.0 software was used for curve fitting and regression analysis to obtain the threshold algorithm. The calculated thresholds were applied to delineate 29 pathologically confirmed lung cancer lesions on PET images and the obtained volumes were compared with the volumes contoured on CT images in lung window. Results The algorithm for defining contour threshold is TH% = 33.1% + 46.8% SUVbg/SUVmax + 13.9%/D ( r = 0.994) by phantom studies. For 29 lung cancer lesions, the average gross tumor volumes ( GTV ) delineated on PET and CT are ( 7.36 ± 1.62 ) ml and (8.31 ±2.05) ml, respectively (t = -1.26, P＞0.05). Conclusion The proposed threshold algorithm for tumor contouring on PET image could provide comparable GTV with CT.

Objective To evaluate the expression of Toll-like receptor(TLR)on the monocyte- derived dendritic cells(DC)from chronic hepatitis B(CHB)patients and to analyze the expression pro- file and significance of the TLR such as TLR3,TLR4,TLR?,TLR8 and TLRg,which are associat- ed with immune response to viral infection.Methods Peripheral blood mononuclear cell(PBMC) centrifugated by the hydroxyethyl starch(HES)centrifugation were cultured and induced into DC by granulocyte-maerophage colony stimulating factor(GM-CSF)and interleukin-4(IL-4),and their mor- phology and phenotype were detected by the inverted microscope and flow cytometry respectively. Monocyte-derived DC were obtained from 10 chronically hepatitis B virus(HBV)-infected patients and 15 healthy volunteers.TLR3,TLR4,TLR7,TLRS,TLR9 expression on immature and mature DC were analyzed by FACS Calibur.DC was pulsed with HBcAg on day 3 and 5,then DC maturation and ability to process HBcAg and to stimulate autogeneic T cells were evaluated.Results Monocyte- derived DC developed different TLR expression patterns as they went through different maturation stages.TLR7,TLR8 expressions on immature DC and TLR3,TLR7 expressions on mature DC were lower in CHB than in control(for TLR7,TLR8 expression on immature DC:75.9%,1.0%vs 98.4%,15.4%,P

Objective To study the effects of nuclear factor-?B(NF-?B)decoy oligodeoxynucleotide(ODN)on the preeclamptic umbilical serum induced expression of precollagen Ⅰ,Ⅲ mRNA and tumor necrosis factor-?(TNF-?)in cultured human umbilical artery smooth muscle cells (HUASMC).Methods Primary cultured HUASMC of normal pregnancy were divided into four groups: group A(HUASMC were incubated with umbilical serum of normal pregnancy);group B(HUASMC were incubated with umbilical serum of preeclampsia);group C(HUASMC were transfected with NF-?B cis decoy ODN 48 h before incubation with umbilical serum of preeclampsia);group D(HUASMC were transfected with NF-?B scramble ODN 24 h before incubation with umbilical serum of preeclampsia).NF-?B cis decoy ODN and NF-?B scramble ODN were transfected with cationic lipofectamine to the latter two groups,respectively.The proliferation of human umbilical artery smooth muscle cells was evaluated by methyl thiazolyl tetrazolium and the apoptosis was analyzed by flow cytometry.The expression levels of precollagen Ⅰ,Ⅲ mRNA were detected by RT-PCR,the expression levels of TNF-? were detected by western blot.Results(1)The proliferation of group B(0.19?0.02)and group D(0.18?0.03)was significantly increased as compared with those of group A(0.11?0.02)and group C(0.14?20.02)(P0.05).(5)The expression of TNF-? of group B(0.74?0.11),group C(0.36?0.09)and group D(0.79?0.12)were significantly higher than that of group A(0.15?0.03)(P0.05).Conclusions NF-?B cis decoy ODN could down-regulate the proliferation,as well as the expression levels of precollagen and TNF-? of HUASMC induced by umbilical serum of preeclampsia.NF-?B may play an important role in the pathogenesis of placental artery abnormalities in preeclampsia.

AIMTo evaluate the therapeutic effects of a left ventricular assist device (LVAD) on pump failure caused by acute myocardial infarction (AMI) in dogs.

METHODSThe pump failure caused by AMI was established in 18 dogs, 9 of them were treated with a LVAD that could expel the autoblood from the left ventricle into the aorta and named the experimental group, and the rest of them were treated with intravenous infusion and served as the control group. The changes of arrhythmia, mortality, pulmonary capillary wedge pressure (PCWP), left ventricular end-diastolic pressure (LVEDP), peripheral artery pressure and the diameter of left ventricular chamber were observed.

RESULTSThe ratio of ventricular extrasystole and the mortality resulted from ventricular fibrillation of the experimental group were lower than that of the control group. The systolic blood pressure of peripheral artery of the control group was significantly lower (< 100 mmHg) than that of the experimental group (>100 mmHg, P < 0.01). The PCWP and LVEDP of the experimental group during all the stages 45 minutes after the procedures were significantly lower than that of the control group (P < 0.01). The left ventricular end-diastolic diameter of the control group was larger than that of the experimental groups (P < 0.01).

CONCLUSIONTo assist circulation by expelling autoblood from left ventricle into aorta in dogs with AMI could reduce the frequency of ventricular fibrillation, improve hemodynamics, and prevent the enlargement of left ventricle. Therefore, it could play an important role in assisting the left ventricular functions.

PURPOSE: Numerous studies have assessed the association of SP110 gene variants with tuberculosis (TB), but the results were inconsistent. Through a comprehensive review and meta-analysis, our study aimed to clarify the nature of genetic risks contributed by 11 polymorphisms for the development of TB. MATERIALS AND METHODS: Through searching PubMed, web of science, China National Knowledge Infrastructure (CNKI) databases, a total of 11 articles including 13 independent studies were selected. The pooled odd ratios (ORs) along with their corresponding 95% confidence interval (CI) were estimated for allelic comparisons, additive model (homozygote comparisons; heterozygote comparisons), dominant model and recessive model. We also assessed the heterogeneity across the studies and publication bias. RESULTS: The results of combined analysis revealed a significantly increased risk of TB for single nucleotide polymorphism (SNP) rs9061 in all five comparisons (allelic comparisons: OR=1.28, 95% CI=1.14–1.44, p<0.0001; homozygote comparisons: OR=2.84, 95% CI=1.84–4.38, p<0.00001; heterozygote comparisons: OR=1.23, 95% CI=1.05–1.43, p=0.009; dominant model: OR=1.32, 95% CI=1.14–1.53, p=0.0003; recessive model: OR=2.26, 95% CI=1.18–4.34, p=0.01). In subgroup analysis, the risk of TB associated with SNP rs9061 appeared to be increased. Moreover, increased risk of TB was also found in Asian subgroup of SNP rs11556887, while decreased risk of TB appeared in large sample size subgroup of SNP rs1135791. No significant association was observed between other SNPs and the risk of TB. CONCLUSION: Our meta-analysis suggested that the variant of SNP rs9061 might be a risk factor for TB.

OBJECTIVETo study the expressions of p35 and p25 and Cdk5 kinase activity in cultured rats hippocampal neurons following X-ray exposure to provide experimental evidence for prevention and treatment of radiation encephalopathy.

METHODSThe hippocampal neurons cultured for 12 days were subjected to a single-dose X-ray exposure of 30 Gy. Western blotting was used to detect the p35 and p25 protein levels, and the effect of pretreatment with roscovitine, a Cdk5 inhibitor, on the apoptosis of the hippocampal neurons following the exposure was examined with 4',6-diamidino-2-phenylindole (DAPI) staining.

RESULTSThe protein level of p35 increased significantly 3.5 and 4 h after the irradiation by 1.51-/+0.13 and 1.45-/+0.14 folds in comparison with the control level, respectively (P<0.01), and the p25 level increased significantly 6 h after irradiation by 1.62-/+0.28 folds (P<0.05). Nuclear condensation occurred in (24.8-/+3.97)% of the neurons 24 h after 30 Gy X-ray exposure, a rate significantly higher than that in the nonexposed cells [(1.82-/+1.08)%, P<0.01) and that in roscovitine-pretreated neurons [(7.74-/+2.27)%, P<0.01).

CONCLUSIONX-ray exposure activates Cdk5 by increasing the p35 and p25 expressions in rat hippocampal neurons, and inhibition of Cdk5 activity with roscovitine can significantly protect the neurons from apoptosis.
