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 evaluate the role of myocardial contrast echocardiography (MCE) to select target vessel, to monitor the opacification zone and to avoid complications during transcoronary ablation of septal hypertrophy(TASH) for hypertrophic obstructive cardiomyopathy(HOCM). Methods In 37 HOCM patients cardiac apex four chamber view, parasternal left ventricular long axis view and left ventricular short axis view were recorded after injection of the myocardial agents and absolute ethanol 5 minutes later respectively. And the opacification zones of the myocardial agents and absolute ethanol were observed. Results Among 37 patients,2 patients gave up treatment because of no appropriate vessel to provide ablation by coronary Doppler flow imaging.Two of 37 patients gave up treatments and did not undergo myocardial contrast echocardiography because of diffused coronary arteries in coronary angiography. Among 33 patients who underwent MCE, 5 patients gave up TASH including one of the opacification of left ventricular mammary muscles, one of the opacification of right ventricular and right ventricular mammary muscles, one for the opacification zone out of the target area and two for the large opacification zone. Other 28 patients underwent TASH successfully. Just after operations and 7 days, left ventricular outflow tract pressure gradient decreased at no less than 50%. Distribution zone of absolute ethanol was smaller than that of myocardial opacification zone in some patients. Conclusions MCE is a credible reference for selection of target vessels in TASH for HOCM.

Objective To explore whether Cl2MDP-loaded gelatin particles can induce the depletion of macrophage or can depress the immunity of macrophage in SD rat models of immune thrombocytopenic purpura(ITP) to treat the ITP rats.Methods SD rats were intravenously injected with 150 ?L of anti-platelet serum once per 24 hr to induce the ITP model.The platelet count was persistently less than 50?109L-1 in these models.After intravenous injection of a group dose of Cl2 MDP-gelatin particles,the platelet counts of these models were examined at the time of 4 hr,24 hr,48 hr,72 hr and 96 hr,respectively.The pathological change of macrophages in spleen was observed by electron microscopy.Results Cl2MDP-loaded gelatin particles can significantly increase the platelet counts of ITP models from less than 50?109L-1 to mean 180?109L-1 in 24 hr after injection.The pathological changes of macrophages were seen under electron microscope,such as degeneration, necrosis and so on.Furthermore,rats pre-treated with Cl2 MDP-loaded gelatin particles can evade the decrease of platelet counts when they were injected anti-platelet serum.Conclusion Cl2 MDP-loaded gelatin particles can promptly,effectively restoreplatelet counts of ITP models to physiological level with a dose dependent manner.So,the targeting therapy of drug-loaded gelatin particles offers a new approach to treat ITP.

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 explore the value of diagnosis and treatment of conization of cervix to cervical intraepithelial neoplasia(CIN)Ⅱ-Ⅲ grade.Methods The data of 76 patients diagnosed as CIN Ⅱ-Ⅲ grade through pre-operative multiple-punch biopsies from July 1st 2006 to June 30th 2007 was retrospectively analyzed.Compared the pathohistology and treatment methods before and after conization of cervix.Results Accordance rate of diagnosis in pre-operative cervical biopsies under vaginoscopy was 48.68%,pathological up-grade were 24 cases(31.58%),among invasive carcinomas were 8 cases(10.53%),pathological down-grade were 15 cases(19.74%).Conclusion Diagnostic cervical conization could enhance the rate of diagnosis,and prevent the omission of invasive carcinomas for the patients with CIN Ⅱ-Ⅲ grade.

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 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.
