Objective To explore the effect of solution-focused approach nursing on the perioperative anxiety and depression of patients with percutaneous renal needle biopsy.Methods Totals of 60 cases who underwent renal biopsy were randomly divided into control group and experimental group with 30 cases each group.Two groups were received regular health education,while the experimental group from 1 day before surgery to 3 days after surgery received the nursing intervention on the solution-focus approach.Before and after surgery,self-rating anxiety scale (SAS),self-rating depression scale (SDS) were used to investigated the patients and compared.Results The incidence of anxiety and depression among all patients was 63.3％ and 66.7％,and no significant difference was found in the score of SAS and before received the percutaneous renal needle biopsy between two groups( P ＞0.05 ).After intervention,the score of SAS and SDS score of experimental group were ( 42.60 ± 6.95 ) and ( 46.80 ± 7.73 ),respectively,and that of control group were ( 50.53 ± 8.63 ),(53.53 ± 10.93 ),and the differences were statistically significant ( P ＜ 0.05 ).Conclusions The intervention solution-focused approach nursing can reduce renal biopsy perioperative patients' degree of anxiety and depression,and improve the quality of nursing.

OBJECTIVETo investigate the clinical manifestations, imaging characteristics as well as prognosis of neonatal polycythemia complicated with brain damage.

METHODSOne hundred and sixteen in-patients with neonatal polycythemia admitted to our hospital during January 2003 to October 2005 were analyzed. Their clinical manifestations were observed. Craniocerebral ultrasonic examination (2D, 3D), CT and MRI were employed to dynamically observe the craniocerebral imaging variances as well as the cerebral hemodynamic variations and near infrared spectroscopy (NIR) was adopted to test the cerebral oxygenation. Twenty-two cases with moderate or severe disease were followed up for 3 to 12 months.

RESULTSOut of the 116 polycythemic neonates, 53 cases had brain damages, of whom 31 had mild, 14 had moderate, and 8 had severe damages. Cranial imaging alterations were mostly ischemic injuries of various areas of different severity. The severity of brain damage was closely related to the duration of polycythemia, oxygen saturation of cerebral tissues as well as cerebral hemodynamic abnormalities. Brain injury was likely to occur in those whose polycythemia persisted for more than three days. The regional saturation of oxygen (rSO(2)) in mild brain injury cases was found to be 52.1%, while it was 47.1% in moderate and severe brain injury cases. Compared to the 58% as found in non-brain injury cases, the variance was found to be statistically significant (F = 104.466, P < 0.01). Among the cases with brain injury, cerebral hemodynamics displayed a slowdown in the blood flow velocity in the cerebral anterior artery and medium artery during the systolic phase and/or the diastolic phase. The abnormality ratio was closely related to the severity of brain injury. Through the chi(2) test the variance was proved to be statistically highly significant (chi(2) = 18.889, P < 0.01), however it was not correlated with the increase of the initial levels of hemoglobin (Hb) and hematocrit (HCT) (P > 0.05). During the follow up, neurological developmental abnormalities of various severity were found to exist in the cases with moderate (5/12) and severe disease (7/8), while cerebral palsy or epilepsy was not yet found.

CONCLUSIONNeonatal polycythemia might tend to bring about a reduction in the perfusion of cerebral blood flow and damaged cerebral oxygenation metabolism which in turn might lead to cerebral ischemic injury, which in some of the moderate and severe cases might lead to long-term neurological complications. Imaging investigations especially craniocerebral ultrasonic examination could be the practical means for the early diagnosis and evaluation of prognosis.

OBJECTIVETo evaluate the effect of irbesartan on the proliferation, apoptosis, and VEGF mRNA expression of human umbilical vein cell line EA.hy926 in vitro.

METHODSThe human umbilical vein cell line EA.hyY926 were treated with various concentrations of irbesartan for 24 h. The cell proliferation after the treatment was detected by CCK8 assay, flow cytometry and FITC Annexin V/PI kit were used to detect changes in the cell apoptosis. RT-PCR was used to evaluate the expression of VEGF mRNA.

RESULTSThere were no changes in cell shape with various concentration of irbesartan. CCK-8 assay showed a greater rate of the cell proliferation in irbesartan group than that in control group with a dose-independent manner after 24 h treatment. After incubation with irbesartan, cell proliferation rate was significant (P < 0.05). FCM analysis showed no significantly changes in the cell apoptosis. Irbesartan increased the proliferation of EA.hy926 cells. At concentration of 1 x 10(-4), 1 x 10(-5), 1 x 10(-6) mol/L, VEGF mRNA expression enhanced either (P < 0.05).

CONCLUSIONIrbesartan could promote the proliferation and up-regulated VEGFmRNA expression in EA.hy926 cell line. This result suggested that in addition to antihypertensive effect, angiotensin receptor antagonist might be a novel therapeutic approach to chronic ischemic heart disease as heart failure.

Receptors play a crucial role in determining the host specificity and tissue tropism of virus. Foot-and-mouth disease virus(FMDV)has been showed to use four integrins, ?v?1, ?v?3, ?v?6 and ?v?8 as receptors to initiate infection and ?v?6 functions as the major receptor.The cDNA encoding bactrian camel integrin ?6 from the lung tissue was cloned and sequenced. The 2367bp cDNA of bactrian camel integrin ?6 encodes a polypeptide of 788 amino acids consisting of a 26-residue putative signal peptide, a 681-residue ectodomain with 8 potential N-linked glycosylation sites and 58 cysteine residues, a 29-residue transmembrane domain, and a 52-residue cytoplasmic domain with a NPLY motif and 1 potential N-linked glycosylation site. The nucleotide sequence similarity of integrin ?6 between bactrian camel and cattle, pig, sheep, human, mouse, Norway rat is 91.1%、91.8%、90.6%、90.5%、83.7%、84.1%, and the amino acid sequence similarity is 94.3%、93.4%、93.4%、93.7%、88.7%、88.6%, respectively. The bactrian camel ?6 gene exhibited the higher sequence homology with the ?6 gene of cattle, pig and sheep, indicating their close genetic relationships. It is possible that host tropism of FMDV may related to divergence in ?6 receptors among different species.
