Objective To study the changes of serum albumin and its relationship with B-Type Natriuretic Peptide(BNP),High sensitivity C-reactive protein(hs-CRP)and left ventricular ejection fraction (LVEF) in patients with acute myocardial infarction(AMI).Methods Serum levels of albumin,BNP,hs-CRP at baseline were analyzed in 95 patients with AMI,and LVEF were measured by echocardiography.All AMI patients were divided into 2 groups based on the values of serum albumin:the hypoalbuminemia group and the normal albuminemia group.Fifty patients without coronary artery disease were selected as controls.The correlations between serum albumin and BNP,hs-CRP,LVEF were analyzed.Results Serum albumin in AMI patients was lower than that in the controls[(38.45±4.60) g/L vs.(43.15±3.11) g/L ;t =8.53,P ＜ 0.001].BNP and hs-CRP levels in the hypoalbuminemia group were higher than that in the normal albuminemia group [(5.24±1.71)ng/L vs.(4.17±1.61) ng/L;t =2.660,P =0.009;(1.64±0.93) mg/L vs.(1.13±1.03)mg/L;t =2.159,P =0.045].LVEF in hypoalbuminemia group was lower than that in the normal albuminemia group[(49.10±11.63) ％ vs.(54.63±9.60) ％ ; t =2.268,P =0.025].Levels of serum albumin were negatively correlated with BNP and hs-CRP in AMI patients(r =-0.465,P ＜0.001 ; r =-0.391,P ＜ 0.001).Levels of BNP were positively correlated with hs-CRP(r =0.492,P ＜ 0.001).LVEF was negatively correlated with BNP values(r =-0.371,P ＜ 0.001).Conclusion Hypoalbuminemia is associated with the prognosis of AMI and may be an important predictor of adverse outcome in patients with it.

OBJECTIVE:To observe the efficacy and safety of amikacin different administrations in the treatment of ventila-tor-associated pneumonia. METHODS:Data of 109 patients with ventilator-associated pneumonia were divided into observation group (58 cases) and control group (51 cases) based on different administrations. All patients received 3.0 g Ceftriaxone sodium for injection,adding into 100 ml 0.9% Sodium chloride injection,intravenously,once every 12 h. Based on it,control group re-ceived 7.5 mg/kg Amikacin sulfate injection,once a day. Observation group received 7.5 mg/kg Amikacin sulfate injection,adding into 20 ml 0.45% Sodium chloride injection,aerosol inhalation,twice a day. The treatment course for both groups was 7 d. Clini-cal pulmonary infection score (CPIS),alanine aminotransferase (ALT),serum creatinine (Cr),oxygenation index (PaO2/FiO2), IL-10,IL-6,C-reactive protein(CRP),tumor necrosis factor(TNF)-α,cumulative mortality after 3 months of treatment and the incidence of adverse reactions before and after treatment in 2 groups were observed. RESULTS:Before treatment,there were no significant differences in the CPIS score,ALT,Cr,PaO2/FiO2,IL-10,IL-6,CRP and TNF-α levels in 2 groups(P>0.05). After treatment,CPIS score,TNF-α,IL-6 and CRP levels in 2 groups were significantly lower than before,observation group was low-er than control group,the difference was statistically significant(P<0.05),and there was no significant difference in IL-10 before and after treatment in 2 groups(P>0.05). PaO2/FiO2 in observation group and ALT,Cr and PaO2/FiO2 in control group were signif-icantly higher than before,PaO2/FiO2 in observation group was higher than control group,ALT and Cr were significantly lower than control group,the differences were statistically significant(P<0.05). The cumulative mortality after 3 months of treatment in observation group was significantly lower than control group,the difference was statistically significant(P<0.05). And there were no severe adverse reactions during treatment. CONCLUSIONS:The efficacy of amikacin by aerosol inhalation is superior to by in-travenous infusion in the treatment of ventilator-associated pneumonia,it can effectively reduce inflammatory cytokine levels and mortality rate,do not increase the incidence of adverse reactions.

OBJECTIVE:To explore the effects of xingnaojing combined with naloxone on related indexes of patients with he-patic encephalopathy. METHODS:In retrospective analysis,76 patients with hepatic encephalopathy were divided into control group(40 cases)and observation group(36 cases)according to drug use. Based on routine treatment,control group was additional-ly given Naloxone injection 1 mg added into 10% Glucose solution 100 mL intravenously twice a day. Observation group was addi-tionally given Xingnaojing injection 20 mL added into 0.9% Sodium chloride injection 250 mL intravenously once a day on the ba-sis of control group. Treatment courses of 2 groups lasted for 2 weeks. HDS score,MMSE score,the levels of blood ammonia,β-endorphin,CRP,IL-6 and TNF-α,the occurrence of ADR were observed in 2 groups before and after treatment. RESULTS:Af-ter treatment,HDS score and MMSE score of 2 groups were significantly higher than before treatment,and the observation group was significantly higher than the control group;the levels of blood ammonia,β-endorphin,IL-6,CRP and TNF-α in 2 groups were significantly lower than before treatment,and the observation group was significantly lower than the control group,with statis-tical significance(P<0.05). There was no statistical significance in the level of IL-10 between 2 groups before and after treatment (P>0.05). There was no statistical significantly in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on routine treatment,Xingnaojing combined with naloxone can significantly improve cognitive function for patients with hepatic en-cephalopathy and reduce peripheral blood neurotoxin and inflammatory factor,moreover,do not increase the incidence of ADR.

OBJECTIVE:To explore the effects of the early use of heparin on the prognosis related indicators of patients with acute respiratory distress syndrome(ARDS). METHODS:Data of 86 ARDS patients were retrospectively analyzed and divided in-to observation group(45 cases)and control group(41 cases)by whether the early use of heparin. Control group received invasive mechanical ventilation,using end-expiratory pressure(PEEP)ventilation method,enteral nutrition support,nasogastric enteral nu-trition suspension 35-40 kcal/(kg·d);patients with combined infection were given Sodium ceftizoxime for injection 2 g,adding in-to 0.9% Sodium chloride injection 100 mL by intravenously infused,twice a day. Observation group was additionally given Hepa-rin sodium injection 6250 units by continuous intravenously pumped. They were treated for 14 d. The cumulative incidence of dis-seminated intravascular coagulation(DIC),and D-dimer,platelet count(PLT)before treatment and after 3,7,14 d of treatment, IL-6,IL-8,IL-10,TNF-α levels before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RE-SULTS:The cumulative incidence of DIC in observation group was significantly lower than control group,with statistical signifi-cance(P<0.05). Before treatment,there were no significant differences in the D-dimer,PLT,IL-6,IL-8,IL-10,TNF-α levels, with no statistical significance (P>0.05). After treatment,D-dimer,IL-6,IL-8 and TNF-α levels in 2 groups were significantly higher than before,while observation group was significantly lower than control group;PLT in 2 groups was significantly lower than before,while observaton group was higher than control group,with statistical significance (P<0.05). There was no signifi-cant difference in the IL-10 level in 2 groups before and after treatment (P>0.05). And there were no obvious adverse reactions during treatment. CONCLUSIONS:Based on conventional treatment,early use of heparin can significantly decrease the DIC rick for ARDS patients,which can improve coagulation disorders,reduce inflammatory response,and dose not increase the incidence of adverse reactions.
