Objective To inhibit the expression of matrix metalloproteinase-2(MMP-2) and matrix metalloproteinase-9(MMP-9) in human kidney tubular epithelial cell(HKC) with specific small interference RNA(siRNA),then to observe whether the expression of intercellular adhesion molecule-1(ICAM-1) on HKC could be influenced.Methods HKCs were transfected with MMP-2,MMP-9 siRNA or irrespective siRNA respectively,untransfected HKC was considered as blank control.Four groups of HKCs were stimulated with 100nmol/L phorbol myristate acetate(PMA) for 18h.Total RNA or protein of cells were extracted with Trizol and RIPA cell lysate respectively,the mRNA expression levels of MMP-2,MMP-9 and ICAM-1 were detected by real time PCR,the protein expression levels of above indexes were detected by western blotting and immunofluorescence combined with confocal laser microscopy.Results The specific siRNA could inhibit the expression of MMP-2 and MMP-9 in HKCs effectively.Immunofluorescence combined with confocal assay demonstrated that while HKCs was stimulated with PMA,the expression of ICAM-1 was up-regulated,which was significantly up-regulated in the group transfected with MMP-9 siRNA(P0.05).Conclusions The inhibitory expression of MMP-9 of HKC may up-regulate the expression of ICAM-1,implying that,besides taking part in the degradation of extracellular matrix,MMP-9 may throw an influence on the proceeding of renal fibrosis by inflammatory pathway.

Objective To observe the effect of eradication of helicobacter pylori (Hp) combined with comprehensive rehabilitation treat-ment on patients with non-alcoholic fatty liver disease (NAFLD). Methods From December, 2015 to April, 2016, 219 patients diagnosed as NAFLD with Hp infection were enrolled, in which 119 patients (observation group) were treated with anti Hp quadruple therapy. They were tested with 13C urea breath test one month after drug withdrawal. The other 100 patients were as control group. The severity of NAFLD was observed with abdominal ultrasound after six months. Results After treatment, Hp was eradicated in 107 cases (90.68%) in the observation group, one dropped out for pulmonary infection. After six months, the severity of NAFLD improved better in the patients eradicated Hp in the observation group than in the control group (χ2=8.397, P<0.05). Conclusion Eradication of Hp combined with comprehensive rehabilita-tion treatment can improve the severity of NAFLD.

Objective To investigate the regulatory effects of IFN-γon Treg cells from HIV/AIDS patients receiving highly active antiretroviral therapy (HAART) for one year.Methods Thirty HIV/A1DS patients whose CD4+T cells were below 350/μ1 were recruited for HAART therapy.Blood samples were collected at the time points of 0,24,48 weeks after HAART.PBMCs were isolated and randomly divided into two culture groups.One group was cultured directly in medium and another group was co-cultured with IFN-γ (40 pg/ml).The supernatants and cells were separated after 5 days of culture for analysis.The concentrations of IL-12 and CD4+CD25+Foxp3 Treg cells were measured by ELISA and flow cytometry,respectively.Results The levels of IL-12 in the supernatants from the culture without IFN-γ at time points of 0,24,48 weeks after HAART were lower than those from the co-cultured group [(37.02±12.76) vs (41.79± 15.02),t=2.336,P=0.03; (41.76±17.01) vs (47.2±14.26),t=2.702,P=0.014; (48.01± 11.84) vs (53.44± 11.30),t =3.14,P =0.003].The percentages of CD4+ CD25 + Foxp3 Treg cells in CD4+ T cells from the direct-cultured group were higher than those from the co-cultured group at the three time points [(10.41±1.10)％ vs (2.40±1.11)％,t=13.89,P=0.000; (8.33±2.03)％ vs (1.99± 0.86)％,t=12.93,P=0.000; (5.65±1.55)％ vs (1.32±0.73)％,t=10.61,P=0.000].Moreover,the results within the same group at the time points of 0,24,48 weeks upon HAART were also significantly different.Conclusion With the interference of HAART,IL-12 levels were increased,while CD4+CD25+ Foxp3 Treg cells were decreased in patients with HIV/AIDS.IFN-γ plays an important role in this process.

Objective To analyze the correlation between quantitative evaluation of high-resolution CT (HRCT) and pulmonary function tests (PFT) in chronic obstructive pulmonary disease (COPD), and evaluate the characteristics of PFT in different CT phenotypes of COPD. Methods 65 patients with COPD underwent CT chest scan and PFT. The dimensions of subsubsegmental apical bronchi of right upper lobes were measured , which included the following parameters:airway wall thickness (T), total airway diameter (D), and pulmonary artery (PA), ratio of airway wall thickness and pulmonary artery (T/PA), thickness diameter ratio (TDR), percentage of wall area (WA%) and percentage of airway luminal area (Ai%). The percentage of total lung area occupied by low attenuation area (LAA%) was measured by lung density software. The relationship between the measurements and PFT parameters were analyzed. Patients were classified into three phenotypes based on the presence of emphysema or bronchial wall thickening evaluated by HRCT. Phenotype A: without or with little emphysema (LAA% < 25%), with or without bronchial wall thickening; Phenotype E: emphysema without bronchial wall thickening (LAA%≥25%, T/PA < 30%); Phenotype M: emphysema with bronchial wall thickening (LAA%≥25%, T/PA≥30%). The characteristics of different CT phenotypes were analyzed. Results LAA% had a good correlation with PFT parameters. PA, T/PA, WA% and Ai% also had correlation with PFT parameters. There was 53 patients of Phenotype A, 12 patients of Phenotype M. PA, T/PA, LAA%and PFT were different in two groups. Conclusions LAA%and airway quantitative measurements in HRCT have certain correlation with PFT parameters. Patients with different CT phenotypes differs in PFT parameters , which can provide reference for clinical diagnosis and treatment.

Objective To further investigate the association among clinical pathology,complement activation and renal secretory IgA (SIgA) deposition in patients with IgA nephropathy (IgAN).Methods The activation of serum complements were detected by immunoturbidimetry and ELISA.Renal deposition of SIgA and activation of complements were detected by immunofluorescence.Then the association among clinical pathology,complement activation and renal SIgA deposition were analyzed in IgAN patients.Results In all 201 patients with IgAN,59 patients had SIgA deposition with higher incidences of mucosal infection history and hematuria (P ＜ 0.05),lower levels of serum cystatin C,β2 microglobulin and lower tubulointerstitial lesion grades and T-grade in the Oxford classification (P ＜ 0.05),when compared with patients without SIgA deposition.Both alternative and mannose binding lectin (MBL) pathways were activated in patients with or without SIgA deposition.Patients with MBL pathway activation had lower estimate glomerular filtration rate (P ＜ 0.01),higher serum creatinine,higher proportion of glomerulosclerosis and S-grade in the Oxford classification,more severe tubulointerstitial lesion (P ＜ 0.05).Conclusions Compared with patients without SIgA deposition,patients with SIgA deposition have a stronger link to mucosal immune.The deposition of SIgA is associated with different clinical and pathological manifestations;however,the complement activation is similar in both groups of patients.Patients with MBL pathway activation show more severe kidney injury.

Objective To understand the life attitude of college students in earthquake-stricken area. Methods 166 college students were conducted by life value scale (LVS) and suicide attitude questionnaire (QSA). Results ①On the LVS, males( (1.85 ±0.57) , (1.73±0.55) ) got significantly higher scores than females ((1.66±0.43),(1.54±0.40)) on survival values-oriented and spiritual values-oriented, and lower scores on tool values-oriented ((2.59±0.46 vs (2.76±0.51) ) , there was significant difference on overcome values-oriented between different grades(F = 3.710, P = 0.013). On the QSA, males (3.01 ±0.51) got significantly lower scores than females (3.28 ±0.51) on the cognition of suicidal behavior difference (t=3.110, P=0.002). There were significant differences on attitude to relationship of suicides between different gender and areas (P<0.05) , and attitude to euthanasia between different gender, grades and subjects (P<0.05). ②Social valuesoriented can predict cognition of suicidal behavior, personal and tool values-oriented can predict attitude to relationship of suicides, the total of life value can predict cognition of suicidal behavior and attitude to relationship of suicides. Conclusion The life value can predict the suicide attitude of college students in earthquake-stricken area, thus the life education should be enhanced to improve their quality of life.

ObjectiveTo investigate the treatment effects of comprehensive nursing intervention on patients with chronic obstructive pulmonary disease(COPD) treated by non-invasive mechanical ventilation with BiPAP mode.Methods96 patients with diagnosed COPD and using non-invasive mechanical ven- tilation with BiPAP mode were randomly divided into the control group(46 cases) which was treated with routine measures and the comprehensive nursing intervention group (50 cases) which adopted comprehen- sive nursing intervention according to experimental design. The frightening degree, incidence rate of com- plications and clinical treatment effect by ventilator were compared between the two groups.ResultsPa- tients compliance with treatment and clinical treatment effect by ventilator in the comprehensive nursing in- tervention group was better than that of the control group. The frightening degree and incidence rate ofcomplications were lower than those of the control group (P < 0.01 ).ConclusionsComprehensive nurs-ing intervention with non-invasive mechanical ventilation with BiPAP mode can improve the treatmentcompliance of COPD patients,reduce complications followed by non-invasive mechanical ventilation andreach the prospective treatment effect.
