Objective To observe the efficacy of multifactor intensive nursing intervention on chronic heart failure patients with outside hospital treatment,including self-management ability and related clinical indicators.Methods By application of prospective study,a total of 215 patients with chronic heart failure discharged from hospital were randomized into the usual care group (105 cases) and the intensive nursing intervention group (1 10 cases).Patients were followed up for 12 months,and 205 patients completed the follow-up.The usual care group only received conventional outpatient follow-up,the intensive intervention group patients received telephone counseling,more detailed clinical follow-up and regular health education.The intervention effect was compared between two groups.Results Compared with the usual care group,the passing rate of sodium/water limit and daily monitoring of weight was higher in the intensive intervention group.Left ventricular ejection fraction and six-minute walking test were better in the intensive intervention group,while the level of NT-pro-BNP was lower in the intensive intervention group.Compared with the usual care group,re-hospitalization rate and incidence of cardiovascular events were lower in the intensive intervention group.Conclusions Multifactor intensive nursing intervention is helpful on improving self-management ability,alleviate cardiac function,reduce re-hospitalization rate and incidence of cardiovascular events for chronic heart failure patients.

Fourty wistar rats were used for experimental study of myocardial infarction (MI )induced by ligation of the left coronary artery. The results showed that the AF and HBFP stalng as well as Ao fluorescence were sensitive in demonstrating the early MI changes occuced 1 ~ 2 hour after coronary arteryligation. The TTC stamg method was reliable for demonstrating the MI margin. Both HBFP and AOfluorescence were under no influeence of the post-mortem autolysis, but the AF reaction were undeithe influence of the early post-mortem autolysis. Four hours were required for complete developemenof MI. The early stage of MI demonstrated by SEM was conslstant with that bv TEM. Both resuhwere influenced by the post-mortem autolysis.

Objective To investigate the clinical spectrum of respiratory viruses in infants and young children with acute lower respiratory infection(ALRI) in Chongqing area from 2003-2007.And to assess the clinical diagnostic value of virus detection in nasopharyngeal secretions(NPS) and serum viral antibody detection for ALRI.Methods Cases of 2 529 specimens of NPS in hospitalized children with ALRI from Apr.2003 to Oct.2007 were taken for detecting 7 common respiratory virus antigens by immunofluorescence assay including respiratory syncytial virus (RSV),adenovirus(ADV),influenza A(IA),influenza B (IB),parainfluenza virus1-3 (PIV1,PIV2,PIV3).Fifty-five thousand eight hundred and eighty-seven samples were tested for ADV-IgM by ELISA.Among those,45 159 cases were further tested for RSV-IgM by ELISA.Results Respiratory virus pathogens were detected in 778 samples out of 2 529(30.76%) including RSV positive in 668 samples (85.86%),PIV3 positive in 75 samples (9.64%),IA positive in 22 samples (2.57%),ADV positive in 15 samples ( 1.93%),only 1 sample ( 0.13%) positive for both PIV1 and RSV. And the positive rate of RSV-IgM was 0.9%-15.2%,and the positive rate for ADV-IgM was about 0.6%-10.6%.RSV infection occured mainly in winter and spring.Conclusions Respiratory virus is the most common pathogen in children with ALRI during the survey period in Chongqing area,especially for RSV infection.The pattern of RSV circulation varied every year with seasonality.It is suggest that this year is peak one for RSV infection from the monthly positive results,especially in Feburary(50%) in 2007.But the infection rate of PIV3,IA,ADV and PIV1 are lower,particularly IB and PIV2 infection have not been seen for the last 5 years.It is fast and accurate to detect RSV antigen and suit to clinical diagnosis by using immunofluorescence assay than other antibody detection.

Objective:To analyze the result of smooth pursuit test(SPT) in unilateral vestibular peripheral vertigo and investigate its influencing factors.Method:Smooth pursuit test (SPT) and spontaneous nystagmus (SN)were examined in one hundred and eighty-five patients with unilateral peripheral vertigo(case group) and 51 normal persons(control group) by Video-Nystagmography (Synapsys, France), and the gain of SPT and SN were selected as the observation parameters in order to analyze the waveform and gain of SPT and the relativity between SN and the gain of SPT.Result:Of the 185 patients, 105(56.8%),72(38.9%) and 8(4.3%) cases producedⅠ,Ⅱ and Ⅲ waveforms respectively. Of these patients, 58(31.4%) demonstrated SN and none had Ⅳ waveform. While of 51 normal persons, 38(74.5%), 13(25.5%) persons producedⅠand Ⅱwaveforms repectively and there were no Ⅲ, Ⅳ waveforms or SN. There was statistical significance between the stong and weak gain of SPT in these two groups. Weak gain was significantly different between two groups. The stong and weak gain of SPT in case group were 0.86±0.06,0.80±0.06; 0.78±0.09, 0.65±0.1; 0.68±0.13, 0.45±0.12. The relativity between SN and the gain of SPT was positive when they had same direction(r_s=-0.63,P＜0.05)and negative when opposite (r_s=0.34,P＜0.05).Conclusion:Ⅰ,Ⅱ,Ⅲ three waveforms of SPT could appear in unilateral vestibular peripheral vertigo and the corresponding gains are gradually decreasing.SN is the influencing factor of SPT.
