Objective To investigate the impact of applying patient-centered care concept on easing the negative moods among the parents of the neonates hospitalized in NICU.Methods The parents of neonates (76 people) hospitalized in NICU from March to May in 2012 were selected as the control group,they conducted normal nursing.The parents of neonates hospitalized in NICU during June and August in 2012 were named as the observation group (81 people).In addition to the normal nursing,they were given nursing intervention according to patient-centered care concept.The anxiety and depression moods of the two groups was analyzed.Results Before the patient-centered care concept intervention,there was no statistical difference of SAS,SDS scores for both groups.For the observation group,the SAS,SDS scores after intervention were significantly lower than those before the intervention.While for the control group,there was no statistical difference of SAS,SDS scores.After intervention,the SAS、SDS scores of the observation group were significantly lower than those of the control group,and the difference was statistically significant.Conclusions The negative moods of the parents of hospitalized neonates can be eased significantly by applying patient-centered care concept intervention.

AIM:To investigate the change of short-chain acyl-CoA dehydrogenase (SCAD) expression during cardiomyocyte apoptosis and to explore the relationship between SCAD and cardiomyocyte apoptosis .METHODS: The neonatal rat cardiomyocytes treated by tert-butyl hydroperoxide (tBHP) were used as the model of cardiomyocyte apoptosis . The cell viability , the expression of SCAD at mRNA and protein levels , the activity of SCAD and the content of free fatty acids were determined .RESULTS:The mRNA and protein expression of SCAD decreased in the cardiomyocyte apoptosis model.Compared with negative control group , SCAD expression and activity were both significantly decreased in siRNA-1186 group, but the content of free fatty acids were obviously increased in the cardiomyocytes .Meanwhile, SCAD siRNA treatment triggered the same apoptosis as cardiomyocytes treated with tBHP .CONCLUSION: Down-regulation of SCAD may play an important role in primary cardiomyocyte apoptosis .Increase in the expression of SCAD may become an impor-tant part in intervening cardiomyocyte apoptosis .

[ABSTRACT]AIM:ToinvestigatethedifferenteffectsofERK1/2/PPARα/SCAD(short-chainacyl-CoAdehy-drogenase) signal pathways on the cardiac hypertrophy induced by insulin-like growth factors 1 ( IGF-1) or phenylephrine ( PE) .METHODS:The neonatal rat cardiomyocytes induced by IGF-1 were used as the model of physiological cardiac hypertrophy , and those induced by PE were used as the model of pathological cardiac hypertrophy .The surface area of the cardiomyocytes, the expression of p-ERK1/2, PPARαand SCAD, the activity of SCAD and the content of free fatty acid in the cardiomyocytes were measured .RESULTS:Compared with the control cells , the surface area of the cardiomyocytes in-duced by IGF-1 and PE were both increased .Compared with the controls , the expression of SCAD and PPARα, and the activity of SCAD in the cardiomyocytes induced by IGF-1 were increased , while the expression of p-ERK1/2 was de-creased.However, the cardiomyocytes treated with PE showed decreased expression of SCAD and PPARα, decreased activ-ity of SCAD and increased expression of p-ERK1/2.Meanwhile, the decrease in free fatty acid in IGF-1-induced cardio-myocytes and the increase in PE-induced cardiomyocytes indicated that the fatty acid utilization was increased in the cardio -myocytes induced by IGF-1, but decreased in the cardiomyocytes induced by PE .CONCLUSION: The changes of p-ERK1/2, PPARαand SCAD in the cardiac hypertrophy induced by IGF-1 or PE indicate that the effects of ERK 1/2/PPARα/SCAD signal pathways are different between physiological cardiac hypertrophy and pathological cardiac hypertro -phy , and that SCAD may be a molecular marker of these 2 different cardiac hypertrophies and a potential therapeutic target for pathological cardiac hypertrophy .

ObjectiveTo investigate the expression of miR-155 and miR-146a in peripheral blood mononuclear cells (PBMC) and plasma of rheumatoid arthritis (RA) patients.MethodsPBMC and plasma were separated from the peripheral blood of 34 RA patients and 15 healthy individuals.Total RNAs were isolated and miRNAs were purified.The levels of miR-155 and miR-146a were determined by quantitative reverse transcription PCR(qRT-PCR).U6 was used as housekeeping control.The amount of target miRNA was normalized relative to the amount of U6(ΔCt=ΔCtmiRNA-ΔCtU6).Relative expression levels were expressed as 2 △-ΔCt.Data were analyzed using SPSS 13.0 software.The test of homogeneity of variance and unpaired t-test was used to compare between groups.P values(2-tailed) less than 0.05 were considered as statistically significant.ResultsThe expressions of PBMC and plasma miR-155 were higher in RA patients than those in the healthy control individuals(0.08±0.08 vs 0.05±0.03,t=-2.225,P＜0.05; 5.9±6.7 vs 1.3±2.0,t=-3.677,P＜0.05).The expression of miR-146a in PBMC and plasma of RA patients and controls were(1.3±1.2 vs 0.8±0.6,t=-2.154,P＜0.05)and(741±1001 vs 300±295,t=-1.669,P＞0.05).According to their DAS28 value,RA patients were divided into high activity group (23 cases,DAS28≥5.0) and low disease activity group( 11cases,DAS28＜5.0).The plasma miR-155 and miR-146a expressions were significantly higher in high activity group than those in low activity group.There were no significant differences in the expression of PBMC miR-155 and miR-146a between the two groups.ConclusionThe expression of PBMC and plasma miR-155 and miR-146a are higher in RA patients.The expression of plasma miR-155 and miR-146a are associated with RA patients' activity.Plasma miR-155 and miR-146a may be potential non-invasive biomarkers for RA diagnosis anddisease activity assessment.

Objective To elucidate the function way of micro RNA(miR)-155 in the differentiation of Th17 cells.Methods CD4+T cells were separated from mice spleens using MACS CD4+T cells separatinge kit and cultured with interleukins [interleukin (IL)-2, IL-23 and IL-6] which could induce CD4+ T cells differentiate into Th17 cells.IL-17 was detected by flow cytometry and enzyme linked immunosorbent assay (ELISA) after transfected with miR-155 mimics or inhibitor lentiviral vectors.The expression levels of miR-155, IL-17A mRNA and Ets-1 mRNA were detected using fluorescent quantitation real-time quantitative polymerase chain reaction (RT-PCR).The si-Ets and miR-155 co-function for Th17 differentiation was analyzed.Data analysis was perfoemed using one-way analysis of variance (ANOVA) test and Dunnett test for pair-wise comparison and t test.P＜0.05 was considered to be statistically significant.Results The CD4+T cells were divided into four groups (the untreated control untreat group, the treatment control treat group, the miR-155 mimnics group and miR-155 inhibitor group).IL-17 was scarcely expressed and secreted in the untreated control untreat group.The cells expression of IL-17 were significantly different among the four groups (F=160.549, P＜0.01).The cells expressing of IL-17 were higher in the miR-155 mimics group (39.86±4.62)％ than those at the miR-155 inhibitor group (22.02±2.81)％, P＜0.01) and in the treated control treat group [(19.44±1.49)％, P＜0.01].The level of IL-17 was also significantly different among the four groups (F=260.813, P＜0.01).The level of IL-17 was higher in the miR-155 mimics group [(1 509±136) pg/ml] than that in the miR-155 inhibitor group [(923± 42) pg/ml, P＜0.01);and in the treated control group [(767±94) pg/ml, P＜0.01).The expression of miR-155 (12.53±0.80 vs 1.78±0.14, 7.16±0.62, 6.47±0.92, P＜0.01) and IL-17A mRNA (46.55±6.71 vs 1.01±0.19,15.62±1.26, 14.20±2.73, P＜0.01) was significantly higher than that in the other three groups, while the expression of Ets-1 mRNA was significantly lower (0.66±0.10 vs 1.19±0.04, 1.01±0.16, 1.37±0.27, P＜0.01).si-Ets-2 was screened because it markedly inhibited the expression of Ets-1 mRNA among the three designed siRNAs.The expression of IL-17A mRNA was higher (17.19±3.58 vs 10.08±0.76, t=-3.361, P=0.028) and the expression of Ets-1 mRNA was lower (0.27±0.01 vs 0.74±0.03, t=-30.275, P＜0.01) in si-Ets-2 group than that in si-Con group when si-Ets-2 or si-Con was co-transfected with miR-155 mimics or inhibitor lentiviral vectors.The expression of Ets-1 protein was lower in si-Ets-2 group than that in si-Con group by Western blotting and the decrease was markedly obvious in the miR-155 mimics group.Conclusion miR-155 can induce CD4+T cells to differentiate into Th17 cells by inhibiting the gene expression of Ets-1.

Objective To study the single nucleotide polymorphisms (SNPs) in IL-23R gene in Chinese Han population with ankylosing spondylitis (AS). Methods SNPs rs11209026, rs1343151, rs11209032 and another three SNPs near them based on their physical distances were genotyped by PCR-directed sequencing. Hardy-Weinberg equilibrium, genotypes and allele frequency analysis were analyzed by SPSS 13.0. Linkage disequilibrium and haplotype analysis were carried out by SHEsis software. Results The difference of genotypes of rs11209032 and the difference of genotypes and allele frequencies of rs6677188 between patients and controls were statistically significant (P＜O.01) ; The two SNPs rs11209032 and rs6677188 had strong linkage disequlibfium (D'=0.925, r2=0.561 ). Haplotype analysis had shown a higher proportion of GAC haplotype in patients and a higher proportion of GTC haplotype in controls. Conclusion These results suggest that IL-23R polymorphisms is associated with susceptibility to AS in Chinese Han population and IL-23R gene may be a susceptible gene of AS.

Objective To search for the genetic and molecular immunity basis of CXCR-1 associated pathogenesis in ankylosing spondylitis (AS) patients. Methods Sequencing analysis was used to detect mutation in the exonic, junctional and promoter sequences of CXCR-1 which might be related with ankylosing spondylitis; the hydrophobicity, conservation and evolutionary distance of the mutated amino acids were also analyzed. Results Six affected individuals in the family were detected with a novel mutation Arg192Gly. The glycine at 192 codon was highly conserved in different species. Arginine and glycine had quite distinct hydrophobicity and BLOSUM score. Conclusion The mutation CXCR-1 (Arg192Gly) detected in these patients might be involved in genetic and molecular immunity mechnisms of ankylosing spondylitis.

Objective To investigate the expression of pancreatic thioredoxin-1 (TRX-1) in rats with acute necrotizing pancreatitis (ANP) and the effect of pretreatment of melatonin on its expression. Methods Male Spraque-Dawley rats (n = 12) were randomly divided to ANP group, melatonin group, control group with 24 rats in each group. The rats in ANP group received three intraperitoneal injections of 25 ml/kg body weight 6% L-arginine at an interval of 1 h to induce ANP. The rats in melatonin group received intraperitoneal injections of 25 ml/kg body weight 6% melatonin 30 min before ANP induction; rats in ANP group and control group received intraperitoneal injections of same amount of saline. Rats were sacrificed at 6 h, 12 h and 24 h after ANP induction. The serum level of amylase was measured and the pathological evaluation of pancreatic tissues was performed. The concentrations of malondialdehyde (MDA) and myeloperoxidase (MPO) in pancreatic tissues were measured. The expressions of TRX-1 protein were detected by immunohistochemistry and the expressions of TRX-1 mRNA in pancreatic tissues were determined by RT-PCR.Results In ANP group, serum level of amylase, MDA, MPO, TRX-1 mRNA and TRX-1 protein in pancreatic tissues were (3 012 ±1 425) U/L, (4.13 ± 1. 85)nmol/mg prot,(7.45 ± 1.26)nmol/mg prot, 0.68 ±0. 18, 66.8 ±8. 1, while they were (1 835±499)U/L, (3.03 ±2.12) nmol/mg prot, (5. 32 ± 1.06) nmol/mg prot, 0.50±0.09, 80. 29 ±8. 14, respectively in melatonin group, the values in melatonin group were significantly lower thanthose in ANP group (P < 0.05). The peak value of TRX-1 mRNA and TRX-1 protwein expressions shifted from 12 h after ANP induction in ANP group to 6 h after ANP induction in melatonin group. Conclusions The expression of pancreatic TRX-1 protein and TRX-1 mRNA in rats with ANP was significantly increased. Melatonin pretreatment could promote pancreatic tissues to express TRX-1 protein and TRX-1 mRNA, and may be protective for pancreatic tissues damages.

Objective To evaluate the effect of transurethral feedback microwave thermotherapy with the ProstaLund CoreTherm Device(PLFT) in high risk patients with benign prostate hyperplasia (BPH). Methods Sixty-six high risk patients diagnosed with BPH, including aged ≥80 in 32 pa-tients, hypertension in 31 patients, diabetes in 5 patients, heart failure in 8 patients, chronic obstruc-tive pulmonary disease in 8 patients, cerebral infarction in 11 patients, fracture, amputation or joint stiffness unsuitable for lithotomy position in 3 patients, abnormal blood coagulation in 4 patients, pan-creatitis in 2 patients, cardiac arrhythmia in 6 patients and malignant tumor in 3 patients, were treated with PLFT using individual power at urethral local anesthesia, resulting in coagulation necrosis in 15%-30% of prostate tissue around urethra. Meanwhile, real-time monitoring the temperature of prostate and the tissue around it was used. All patients were evaluated by comparing volume of pros-tate, maximal urinary flow (Q_max), international prostate symptom score (IPSS) and quality of life questionnaire (QOL) in pre-treatment and three months after respectively. Results All of patients well tolerated PLFT. There was bleeding lightly, infection lightly and temporary incontinence. There was no severe surgical complication. After three months, the volume of prostate reduced from 62. 2 ml to 44.5 ml; IPSS decreased from 23. 4 to 11.7; QOL decreased from 4.5 to 2.4; Q_max rised from 4, 2 ml/s to 11.2 ml/s. All differences reached significance. Conclusion PLFT is one of effective and safe treatments for patients with BPH especial BPH complicating with severe conditions.

Objective To investigate the approach and safety of minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi. Methods Clinical data of 21 cases with symptomatic caliceal diverticular calculi were retrospectively reviewed. Twelve females and 9 males aged 22 to 57 years old. The average diameter of caliceal diverticulum was 3.7 cm (2.5-7.0 cm) and average diameter of calculi was 2.3 cm (0.8-3.5 cm). The patients underwent flexible ureteroscopic lithotripsy, PCNL or mPCNL, laparoscopic techniques and laparoscopy-assisted transperitoneal PCNL, respectively. Four cases underwent flexible ureteroscopic lithotripsy. PCNL (2 cases) or mPCNL(5 cases)were performed in 7 cases. Nine cases underwent laparoscopic techniques. Laparoscopyassisted transperitoneal PCNL was performed in 1 case. Results The operations were performed successfully in 21 cases. No case need to transfer to open surgery during the operation and no major complications like perforation or organic injury were noted. One case with iatrogenic arteriovenous fistula of the kidney after 1 week postoperative was cured by delayed hemorrhage 2 days later, while clinical symptoms of 2 cases with residue calculi relieved. 19 cases without residue calculi were followed up for 6 to 12 month without recurrence. Conclusions After handling indication of treatment efficiently and creating advisable therapeutic decision-making, minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi appears to be effective and safe.
