Objective To investigate the effect of L-arginine on expression of protein kinase C(PKC)mRNA during pulmonary ischemia and reperfusion injury(PIRI)in the rabbits.Methods Single lung ischemia and reperfusion animal model was used in vivo.The rabbits were randomly divided into three groups(n=9,in each),sham operated group (Sham),PIR group(I-R)and PIR+L-arginine group(L-Arg).Changes of several rariables including malondialdehyde (MDA),superoxide dismutase(SOD),malandialde hyde(MDA),nitril oxide(NO),wet to dry ratio of lung tissue weight(W/D)and index of quantitative assessment(IQA)of histolngic lung injury were recorded at 60 minutes after reperfusion in lung tissue.Meanwhile the location and expression of PKC mRNA were observed.Lung tissue was prepared for light microscopic and electron microscopic observation at 60 minutes after reperfusion.Results In comparison with group I-R,PKC mRNA strongly expressed in intima and extima of small pulmonary artery as well as thin-waU vessels (mostly small pulmonary veins).The average optical density values of PKC-?,?and?mRNA in small pulmonary veins in L-Arg group had significance(all P＜0.01);SOD increased while MDA,W/D and IQA decreased at 60 minutes after reperfusion in lung tissue(P＜0.01 and P＜0.05).A morphologically abnormal changes of the lung tissue,were lessen markedly in L-Arg group.Conclusion L-arginine possess notably protective effects on PIRI in rabbits by activating PKC-?,?and?mRNA expression in lung tissue,raising NO level,dropping oxygen free radical level and decreasing lipid peroxidation.

Objective To observe the effect of the decontamination bundle of care for prevention of nosocomial infection after cardiac surgery. Methods Patients who underwent routine perioperative care from January 2012 to December 2013 for cardiac surgery were enrolled as the control group, while patients with bundle of care from May 2014 to April 2016 as the decontamination group. The care bundle included preoperative nasopharyngeal screening for methicillin-resistant Staphylococcus aureus (MRSA), perioperative systematic decontamination, isolation and antibiotic prophylaxis (mupirocin and glycopeptide) for MRSA carriers. The clinical data and nosocomial infection was collected and statistically analyzed. Results There were 712 cases in the control group and the incidence of nosocomial infection was 8.29% (59/712) including 4 MRSA cases. The decontamination group enrolled 791 cases with 5.56% (44/791) nosocomial infection including 2 MRSA cases. The bundles of care inhibited the nosocomial infection significantly (χ2=4.356, P<0.05), and there was a trend of decrease on MRSA infection. A total of 6 cases (0.76%) in the decontamination group were detected as MRSA colonization, but none of them got infected. Conclusions The care bundle of perioperative decontamination is useful to prevent nosocomial infection in cardiac surgery, especially to MRSA infection.

OBJECTIVETo estimate the reliability of heart-type fatty acid-binding protein (H-FABP) for identifying acute coronary syndrome (ACS) in the early stage of chest pain onset.

METHODSThis investigation was conducted based on a small population consisting of 40 healthy individuals, 19 established AMI patients and 20 unstable angina pectoris (UAP) patients. Serum H-FABP concentrations were measured in these subjects by sandwich ELISA, and receiver operating characteristics (ROC) curves for H-FABP for diagnosing AMI and UAP against normal subjects were then generated respectively. The areas under curve (AUCs) were calculated, and 0.5 was defined as the critical value of AUC to evaluate the diagnostic ability.

RESULTSThe concentrations of H-FABP in healthy individuals, AMI patients and UAP patients were 1.29+/-0.64, 24.45+/-32.40 and 1.95+/-3.11 ng/ml, respectively; AUC (AMI) and AUC UAP were 0.978 (95%CI: 0.948-1.000) and 0.503 (95% CI: 0.334-0.671) respectively, and the former was significantly greater than 0.5.

CONCLUSIONSIn the early stage of chest pain onset H-FABP detection is sufficient in distinguishing AMI patients from healthy individuals, but not capable of distinguishing UAP patients from healthy individuals. H-FABP may be used as a diagnostic biochemical marker in the early stage of AMI.

OBJECTIVEN-acetyltransferase 2 (NAT2) and cytochrome P450 2EI (CYP2E1) play a crucial role in the drug metabolic process. The aim of this study was to understand the genotype and phenotype polymorphisms of NAT2 and CYP2E1 in the Han Chinese pediatric population in order to provide a theoretical basis for individualized drug treatment.

METHODSA total of 341 (211 males and 130 females) randomly sampled Han Chinese children, aged from 2 months to 14 years, were enrolled in this study. Genotyping was carried out by PCR method, and metabolic phenotypes were identified.

RESULTSIn this study population, wild genotype was found as a major genotype in seven SNPs of NAT2, rs1801279, rs1041983, rs1801280, rs1799929, rs1799930, rs1208 and rs1799931. The frequency of NAT2 fast metabolism was highest (61.3%), followed by middle to slow metabolism (34.1%). Wild genotype also predominated in the four SNPs of CYP2E1 (rs2031920, rs3813867, rs6413432 and rs72559720) named as CYP2E1*5, *6 and *2, with a frequency of 61.3%, 60.1% and 99.4% respectively. As the relationship between CYP2E1 genotype and phenotype was unknown, phenotyping of CYP2E1 was not done.

CONCLUSIONSThe important SNPs of NAT2 and CYP2E1 are predominantly wild genotype in the Han Chinese pediatric population. Fast metabolic phenotype predominates in important SNPs of NAT2.

Objective To assess the effect of anemia on long-term outcomes in patients with acute coronary syndrome(ACS) undergoing pereutaneous coronary intervention(PCI). Methods In 3136 patients presenting with ACS,636 patients were anemic. The clinical features, mortality and major cardiocerebral events including non-fatal acute myocardial infaret,revascularization and non-fatal cerebral stroke were compared in patients with or without anemia. The average follow-up period was 550 days. Results Anemic patients were older and had a higher percentage of comorbidities compared with nonanemic cohorts. Compared with nonanemic patients, anemic patients had higher mortality (4.7% versus 1.5% ,P <0. 001) and a higher major adverse end point events,including nonfatalmyocardial infarction, stroke and revaseularization (14.2% versus 11.0%, P = 0.032). After adjustment for comorbidities, anemia was associated with a higher risk of mortality after percutaneous coronary intervention (adjusted hazard rate ratioRR2. 166 ;95% CI 1. 298-3. 612 ;P =0.003). Conclusion Anemia before PCI is an independent factor for predicting the long-term mortality of ACS.

Objective To understand the current epidemic and immunity status of hepatitis B virus in Ma’anshan City, and to compare the prevention and control effect after the adjustment of hepatitis B vaccine immunization strategy. Methods Multi-stage random sampling method was used to select 10 investigation points in the whole city, a random sample of 3 460 people under 60 years old was included according to urban and rural stratification. questionnaires and blood were collected from the subjects, and domestic enzyme linked immunosorbent assay (ELISA) was used for hepatitis B immunoglobulins detection. Results The total positive rate of hepatitis B virus surface antigen (HBsAg), hepatitis B virus surface antibody (HBsAb) and Hepatitis B virus (HBV) infection was 3.32%, 51.21% and 29.16% respectively. The positive rate of HBsAb in urban area was higher than that in rural area ( 2=28.204, P<0.001). The positive rate of HBsAb was significantly different between the medical and nursing staff and other occupational groups ( 2=22.772, P<0.001). The difference of HBsAb positive rate before and after HepB vaccine content adjustment was statistically significant ( 2=90.331, P<0.001). The rate of HepB decreased with age ( 2trend=1 984.342, P<0.001). Conclusions Since HepB was incorporated into the immunization program, hepatitis B prevention and control in school-age children has achieved remarkable results. More attention should be paid on the low positive rate of HBsAb in students and the low immunization rate of HepB in adults.
