Objective To explore causes and high risk electrocardiogram expression of cardiac syncope caused by malignant rapid ventricular arrhythmia.Methods Forty-eight patients were analysed, they had cardiac syncope once or more that after which were admitted to the hospital. Results The basic causes of cardiac syncope were individed following types in 48 patients: coronary heart disease with acute or dated myocardial infarction,dilated or hypertrophic cardiomyopathy,hypokalaemia were ordinarist inducer.Torsade de pointes(TdP) were most common type of malignant rapid ventricular arrhythmia.They had some high risk electrocardiogram expression: secondary long QT syndrome,Brugada's syndrome,idiopathic abnormal J wave,complex ventricular ectopic beats,acute myocardial infarction with ST-T electrical alternation; or extensive anterior myocardial infarction with tombstone ST segment elevation,dilated cardiomyopathy with advance QRS complex low voltage.They were different electrocardiographic and clinical characteristic. Conclusion The cardiac syncope caused by malignant rapid ventricular arrhythmia is not single and independent clinical entity, which presents different the causes and high risk electrocardiogram expression.

Objective To compare the effects of peripherally inserted central catheter(PICC)and venous port access (VPA)on the complication incidence of breast cancer.Methods A total of 191 breast cancer patients with VPA and 218 ones with PICC for chemotherapy from January 2012 to January 2014 were involved.The two groups were compared in respect of incidence of complications during intubation.Result The complication incidence in the VPA group was lower than the PICC group(P<0.05). Conclusion VPA is an ideal pathway for intravenous infusion in breast cancer patients undergoing chemotherapy.

Objective To investigate the nutritional risks in hospitalized patients with liver diseases and work out nursing countermeasures.Methods Forty patients with liver cirrhosis, 40 patients with primary liver cancer and another 40 revisiting after liver transplantation involved in the investigation with a self-designed general information questionnaire and the nutritional risk screening 2002. The three groups were compared in terms of nutritional risks.Results Among the total 120 patients,38.3%(46/120)of them took the nutritional risk and even 12.5%(15/120)had the risk of undernourishment.The risk in the patients with liver cirrhosis was higher than that in the other two groups(χ2=9.899 and 11.4299 and P=0.002 and 0.001,respectively).Conclusions The nursing staffs should pay attention to the nutritional status of patients with liver diseases, especially the patients with liver cirrhosis.It is necessary to take effective measures in order to improve the nutritional status of the patients to reduce the nutritional risks.

OBJECTIVETo observe the effects of danshensu on function of endothelial progenitor cells (EPCs) from peripheral blood which were damaged by oxidative low density lipoprotein (Ox-LDL). And study its possible mechanism.

METHODTotal mononuclear cells (MNCs) were isolated from peripheral blood by ficoll density gradient centrifugation, and were identified by demonstrating the expression of CD34, VEGFR-2 and AC133 with flow cytometry, to sure that all the cells needed were EPCs. Then the cells were plated on fibronectin-coated culture dishes. After incubation for 7 days, attached cells were collected and divided into three groups: Control group, Ox-LDL group, danshensu intervention group, stimulated with different cencentrations of danshensu (2, 10 and 50 mg x L(-1)), adhesion assay respectively. EPCs adhesion assay were performed by replating those on fibronectin-coated dishes, then adherent cells were counted. And take cell supernate of each group to carry on the SOD, MDA content examination.

RESULTOx-LDL impaired EPC proliferative and adhesive capacity. In Ox-LDL group, The SOD content obviously drops, the MDA content obviously elevates. After danshensu interventing for 24 h, adhesive EPCs and migratory EPCs were significantly increased. Compared with Ox-LDL group, the SOD content of Danshensu intervention group obviously increased and the MDA content obviously reduced.

CONCLUSIONdanshensu could improve proliferative and adhesive capacity of EPCs that were impaired by Ox-LDL. The mechanism might relate to the oxidation resistance damage.

OBJECTIVETo examine the change of puerarin on the expression of apelin and its receptor of the two-kidney, one-clip (2K1C) rats.

METHODTirty male Sprague-Dawley rats were randomly divided into normal control group (C), model group (M) and puerarin group (P). The mean of carotid arterial pressure (mCAP), mean of left ventricular end diastolic pressure (LVEDP), and the weight ratio of left ventricular mass (left ventricle plus septum) to bodyweight (LVM/BW) were measured to evaluate the model of 2K1C renal hypertension. The concentrations of apelin in the plasma and left ventricle (LV) were measured with radioimmunoassay. Apelin mRNA and APJ mRNA expressed in the LV were examined by reverse transcription-polymerase chain reaction (RT-PCR). The peptides of apelin and APJ expressed in the LV were detected with immunohistochemistry (IHC).

RESULTCompared with C group, the mCAP, LVEDP and LVM/BW of M group were higher 36.58%, 333.8% and 20.24%, respectively (P<0.05, P<0.01, P<0.01). Compared with M group, LVEDP and LVM/BW of P group were lower 65.24% and 13.12%, respectively (both P<0.05). However mCAP was of no significant difference between these two groups. The levels of apelin-36 in the plasma and LV of M group were respectively higher 18.56% and 207.38% than those of C group (both P<0.05), while ones of P group were lower 24.21% and 49.40% than those of M group (both P<0.05). The expressions of apelin mRNA and APJ mRNA at left ventricle tissues of 2K1C rats were higher 77.66% and 119.00% (both P<0.05) than those of C group. The ones of P group were lower 27.40% and 45.66% than those of M group (both P<0.01). The IHC results indicate that the expressions of apelin and APJ peptides at left ventricle tissues of 2K1C rats were higher 129.51% and 154.1% (both P<0.01) than those of C group, respectively. Whereas the ones of P group were lower 65.36% and 62.87% than those of M group (both P<0.01).

CONCLUSIONThrough regulating apelin/APJ system puerarin has protective effect on the development of left ventricular hypertrophy by renal hypertension.
