Objective To investigate the prognostic factors in patients with sepsis and to provide the theoretical basis for clinical diagnosis and treatment. Methods A total of 141 septic patients were analyzed retrospectively. Patients were divided into two groups:those who were alive at time of ICU discharge ( survivors;n=83 ) and those who died or to give up before terminal stage ( nonsurvivors;n=58 ) . Then the clinical data were statistically ana-lyzed. Results In the death group: age, APACHE II score, blood urea nitrogen, serum creatinine, C-reactive protein were significantly higher than the survival group (P<0. 01) while albumin, pre albumin were lower than that in the survival group (P<0.01). The Logistic regression analysis illustrated: age ( > 60 years), APACHEIIscore ( >20 score) and blood urea nitrogen ( > 9 mmol/L) , serum creatinine ( > 176 μmol/L) , C-reactive protein level were independent predictors of death in patients with sepsis ( P<0 . 05 ) . Then drew the receiver oper-ating characteristic curve ( ROC curve) and analyzed the respective risk factor for predicting prognosis value of sep-sis with the help of ROC curve. Conclusion Age, high APACHE II score in early sepsis, increased urea nitro-gen, elevated serum creatinine and increased C-reactive protein levels were regarded as prognostic value indicators for adverse clinical outcomes in patients with sepsis.

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.

OBJECTIVETo study the anti-asthmatic effect of sodium ferulate (SF) and its mechanism in guinea pig asthmatic model.

METHODSGuinea pigs were sensitized with ovalbumin as animal asthmatic model and treated with 3 different concentration of SF for 8 days. Levels of endothelin (ET) and nitric oxide (NO) in blood and lung tissue, and eosinophil (EOS) in blood and bronchoalveolar lavage fluid (BLAF) was counted at the end of trial.

RESULTSSF could significantly lower the ET content and increase the NO concentration in serum and lung tissue, reduce the number of EOS in blood and BLAF (P < 0.05, P < 0.01). Stronger effect was showed in the high dose group.

CONCLUSIONMechanism of anti-asthmatic action of SF might be to increase NO concentration, lower ET content, alleviate EOS infiltration.

Objective To analyze the correlationship of ACE I/D gene polymerphisms with the anti-hypertensive efficacy of irbesartan among essential hypertension (EH) patients in Yunnan han people.Methods One hundred EH patients hypertension were treated with irbesartan 150mg once daily for 4 weeks,and anti-hypertensive efficacy were monitored during the treatment.Results There was a significant difference between anti-hypertensive efficacy of irbesartan among different genotype groups,DD group ＞ID group ＞Ⅱ group (P ＜ 0.05) Conclusions There is different therapy responsiveness in diffenent genotypes.ACE I/D polymorphism may be an important hereditary factor that impacts the efficacy of irbesartan.

A new instrument for measuring pressure pain strength to different bodily parts is introduced in this paper. For a new measuring appliance, it can be used conveniently for detection and evaluation of a patient's pressure pain threshold value, and for the research of bodily channels and network vessels. The system uses silicone oil as pressure conducting medium of a transducer, and five pressure detecting probes with different surface areas are designed to meet the requirements of the parts to be measured. The system has digital lock function for easy operation.
