Objective To investigate the psychological status of family members of patients with depression, and discuss the health education pathway. Methods The families of 200 inpatients with major depression accepted systemic health education about depression according to the investigation of the self-designed questionnaire. They were assessed with Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS) when the patients admitted and accepted 8 weeks of treatment. Results The score of SDS was more than 50 in 76.5% families of patients, and it was 79.0% for SAS when admission. The scores of SDS and SAS reduced after education (P<0.01). Conclusion Health education can improve the psychology of family members of patients with depression.

Objective To assess the value of echocardiography in guiding surgical operation approach of ventricular septal defect (VSD). Methods A total of 200 patients with VSD underwent surgical repair. The type of VSD was determined with echocardiography before operation and the results were analyzed in comparison with operation approach. Results There was significant accordance in the type of VSD detected with echocardiography and the surgical findings, and the coincidence rate of 80.00%. The transatrial approach was chosen in patients with perimembranous VSD, subseptal cusp VSD and simple membranous;the anspulmonary approach was chosen in subarterial VSD, while transventricular approach was chosen in muscular VSD or VSD with large size. Combined approach was suitable in VSD complicated with intracardiac malformations. Conclusion The type of VSD determined with echocardiography plays a key role in the selection of operation approach, and is benefit to reducing complications.

In this experiment, we introduced human interleukin-2(lL-2)gene and Neomycin resistance (Neo~R) gene into a human lung adenocarcinoma cell line GLC, using a retroviral vector PLXSN. The positive cells obtained by selecting in G418 were compared with the wild-type cells. We observed their growth characteristics in vitro and the quantity of IL-2 in the culture supernatants. PCR result demonstrated the integration of foreign genes into tumor genome DNA after transfection and permanent existence. Under electron microscope, what can be seen was the surface villi of trans-duced-cells are less and shorter. It deserves further investigation to determine whether the change of cell surface influence metastatic ability of cells.

Objective By exploring echocardiographic ch aracters and pathologic examination of noncompacted ventricular myocardium(NVM), to prevent life-threatening arrhythmias and embolism. Methods Echocardiographic examinations included four-chamber view, two-chamber view and short axis view of left ventricle, with an emphasis on observing left ventricular myocardium and endocardium approach to one-third of apex of heart. Results All 24 patients showed obvious echocardiographic findings characterized by prominent and excessive myocardial trabeculations and deep intratrabecular recesses in the affected ventricular cavity. Three cases complicated with other congenital heart malformations, 20 cases with congestive heart failure and only 2 cases were asymptomatic. Coronary arteriography was performed in 13 cases and revealed normal findings. Two cases eventually underwent heart transplantation because of severe congestive heart failure. Gross and histological findings demonstrated prominent muscular trabeculations, with deep intratrabecular recesses into lesion heart. Serial section from the base of the ventricle toward the apex revealed gradually weaker myocardium. Noncompaction of ventricular myocardium showed a thin, compacted epicardial and an extremely thickened endocardium by fibrous tissue. Conclusions Noncompaction of ventricular myocardium has characteristic echocardiographic manifestations and specific pathologic changes, which are different from those of primary enlarged type of cardiomyopathy.

Objective To show left anterior descending artery and interventricular septal branch Doppler flow and Doppler flow spectrum using coronary Doppler flow imaging,provide reference to select target artery,and judge collateral circulation formation after percutaneous transluminal septal myocardial ablation (PTSMA) of hypertrophic cardiomyopathy. Methods In 28 patients with hypertrophic cardiomyopathy left anterior descending artery and interventricular septum branch flow were displayed using coronary flow Doppler imaging system before and after PTSMA,and flow velocity were measured by Doppler spectrum. Results In 22 patients the target arteries were successfully selected in the first time using coronary flow Doppler imaging combined with coronary angiography and proved by the results of PTSMA. In 2 patients PTSMAs were performed successfully after additional choosing other interventricular septal branch. Therefore,PTSMAs in 24 patients were performed effectively in total. In 4 patients PTSMAs were given up due to vessel thinness and suffusion of interventricular septal branch in 2 patients,myocardial contrast agent distributing right ventricular and right ventricular papillary muscle during operation in one patient and contrast agent distributing left ventricular papillary muscle in another patient. Left ventricular flow tract pressure rebounded in 5 patients postoperatively,and neighboring interventricular septum branch extending to melting area were seen in 3 patients accompanied by flow velocity increasing. Melted vessel nub markedly prolonged in 1 patient. Conclusions Coronary Doppler flow imaging can directly reveal interventricular septum branch flow in hypertrophic cardiomyopathy,provide detailed hemodynamic information for myocardial PTSMA and monitor PTSMA for hypertrophic cardiomyopathy effectively and reliably.

Objective To investigate the value of screening bridge vessels before coronary artery bypass graft(CABG) by ultrasonic examination. Methods To analyze the ultrasonic result of internal mammary arteries,carotid arteries,and radial arteries before CABG. Results Among the 140 cases,11 internal mammary arteries were not qualified,14 of 74 radial arteries were not qualified. And the stenosis of carotid arteries were present in 28 cases. Conclusions It is valuable to examine the bridge vessels before CABG.

Objective To discuss the influence of health education pathway on detaining time of thoracic drainage tube and standardize the nursing procedure for postoperative patients.Methods Forty five patients after thoracotomy from March to December in 2006 were set as the control group.Fifty patients of the same kind from January to September in 2007 were named the test group.The control group received conventional nursing education.The test group received health education on the day of operation,the first,second,third and fourth day after operation from specified nurses according to health education pathway.The contents included psychological nursing,pain management,respiratory function and physical training and enhancement of drainage efficacy.The average indwelling time of thoracic drainage tube was recorded.Results The average indwelling time of thoracic drainage tube in the test group and the control group was(74.40±8.88)h and(91.68±10.08)h respectively,which showed statistical difference,P＜0.01.Conclusions Application of health education pathway effectively shortened indwelling time of thoracic drainage tube as well as reduced pain and medical costs of patients.

Objective To discuss the drug resistance and the vicissitude of Pseudomonas aerugi-nosa in Intensive Care Unit (ICU), in order to provide basis for rational use of antibiotics in clinic. Methods Identification of bacteria was performed by applying ATB Expression Identification System produced by BioMerieux Company; drug susceptibility tesr was done by using K-B method. The drug resistance of Pseudomonas aeruginosa was compared between ICU and general wards; and then the difference of drug resistance was investigated between 2006 and 2007. Resnlts The more sensitive an-tibiotics to Pseudomonas aeruginosa in ICU of our hospital were as follows, amikacin (resistance rate 6.7%-9.4%), eiprofloxacin (resistance rate 7.7%-24.7%), cefoperazone/sulbactam (resistance rate 11.5%-34%), ceftazidime (resistance rate 11.5%-37.7%), aztreonam (resistance rate 20.2%-40.6%). The drug resistance rate of ICU was higher than that of the general wards, and the drug re-sistance rates to ciprofloxacin, ceftazidime, cefoperazone/sutbaetam,meropenem, imipenem and aztreo-nam in 2007 were significantly higher than those in 2006 (P<0.01). Conclusion The drug resistance rate of Pseudomonas aeruginosa in ICU of our hospital was very high,and it is rising year by year. So it is important to retrospect the results of the drug resistance periodically and provide the up-to-the-mi-nute data of epidemiology and vicissitude of drug resistance.

Objective To investigate the effects of Shuxuetong Injection (SXT ) on expressions of cell apoptosis and TLR4 a-round ischemic area after focal cerebral infarction in rats and to discuss its neuroprotective mechanism on ischemia-induced brain in-jury .Methods The SD rats were subjected to establish the model of middle cerebral artery occlusion (MCAO)by nylon monofila-ment suture ,then were randomly divided into the sham-operated group ,the model group and the SXT treatment group ;the cell ap-optosis and the expressions of TLR4 mRNA and protein around ischemic area at 12 ,24 ,48 ,72 h after cerebral ischemia were detec-ted respectively by TUNEL test mediated with DNA ,RT-PCR and immunohistochemistry .Results In the model group ,the number of TUNEL positive cells ,the expressions of TLR4 mRNA and protein were gradually increased at 12 h ,reached the peak at 24 h , then decreased and were still higher than those in the sham-operated group(P<0 .01);in the SXT treatment group ,these expres-sions after 24 h were lower than those in the model group (P<0 .05)and declined as the treatment time increase(P<0 .05) .Conclu-sion In subacute stage of cerebral ischemia injury ,apoptosis is related with the expression of TLR4 ,SXT may inhibit apoptosis , down-regulate the expression of TLR4 around ischemic area ,this may be one of the mechanisms of neuroprotection .
