The incidence of dextrocardia is lower. The dextrocardia is often associated with congenital anatomical abnormalities. The patient with normal cardiac structure of dextrocardia and severe coronary heart disease that needs coronary artery bypasss is rarer. This article summarizes the perioperative management and surgical experience of dextrocardia with bypass surgery via a clinical case.

Objective To establish a rat model of liver metabolism profile in chronic heart failure (CHF), to explore the dynamics of liver metabolism in CHF from the point of view of metabolism, and to find the characteristic metabolites valuable for the molecular mechanism and management of CHF.Methods Twenty male Wistar rats were assigned to the CHF group to receive aortic coarctation or to the control group to receive sham surgery, and were bred for 24 weeks following surgery.The metabolic profiling of the rat liver tissues was analyzed on a metabonomics research platform. Orthogonal partial least squares-discriminant analysis ( OPLS-DA) model and principal component analysis ( PCA) model were established for liver tissues of the CHF rats, and the characteristic metabolites were finally derived by data processing with SPSS 19.0 software.Results The PAC and OPLS-DA models were established successfully.Ten characteristic metabolites with significant differences between the CHF and control groups, including lysophosphatidyl choline, lysophosphatidyl ethanolamine, oleic acid, glycocholic acid, and dehydroepiandrosterone sulfate, were screened and identified from the models.Conclusions The metabolic disorders in CHF rats are well fitted to the established metabolic profile models, and these identified characteristic metabolites may provide reference for the pathophysiological molecular mechanism and management, etc., of chronic heart failure.

Objective To investigate endoscropic assist in rat orotracheal intubation.Methods 40 rats were randomly divided into two groups.The procedure time, total time, intubation frequency,the success rate of the first intubation and the survival rate in 24h were compared between the conventional group and the endoscropic group.Results The total time in two groups were nearly the same.But the procedure time and frequency of intubation were significantly less in the endoscropic group than those in the conventional group.The success rate of the first intubation in the endoscropic group was obviously higher than that of the conventional group.There was no obviously difference between the survival rate after extubation in 24h between groups.Conclusion Endoscropic assist is superior to the conventional method and worth promoting.

Objective To investigate the status of genotype of the KPC(Klebsiella pneumoniae carbapenemase)-encoding genes in Pan-resistant K. Pneumoniae, isolated from the 98th Hospital of People' s Liberation Army, Huzhou district, Zhejiang province, China. Methods 19 strains of Pan-resistant K. Pneumoniae were isolated from the inpatients between November, 2008 and July,2009. Phenotypic confirmatory test for suspected carbapenemases production were carried out by Modified Hodge test. Carbapenemase gene of blaKPC was analyzed by PCR and verified by DNA sequencing. Results In 19 strains of K. Pneumoniae, the positive rates of Modified Hodge test and gene of blaKPC were both 100.0%. These genes all belonged to blaKPC-2 subtype confirmed by nucleotide sequence analysis. Among them, the blaKPC-2 gene sequence of the HZ001 strain (its original serial number was HZ9871 ) had been registered in GenBank (GenBank Accession Number: GU086225).Conclusion All of the Pan-resistant K. Pneumoniae isolated from the inpatients harbored blaKPC-2 type carbapenemases gene and causing an outbreak in a hospital. Carbapenemases that producing type KPC-2 might be the major reason which causing the resistance to Carbapenems antibiotics.
