ABSTRACT
Infective endocarditis (IE) refers to the pathogenic microbial infect the endocardium, valves or intima adjacent to the cardiac arteries through the bloodstream with the formation of vegetations. Valves are the most frequently affected sites. Here, we described a 49-year-old female, who admitted to respiratory outpatient department in the Third Xiangya Hospital, Central South University for long time of fever. Chest computer tomography (CT) found a thick wall cavity in the apex of the right lung with smooth wall and fluid plane, without enhancement, which was considered as inflammation and tuberculosis to be excluded. Echocardiography showed vegetations on the aortic valve, where abscess was found on the root. Accidentally in surgery, a patent ductus arteriosus (PDA) was found. The surgeon closed the PDA and performed aortic valve prosthetic valve replacement. Bacterial colony of coccus was found in the pathological tissue, which was consistent with the diagnosis of valvular degeneration with infection. Lung lesion was obviously absorbed after 6 weeks of treatment with vancomycin, which has been confirmed as a sensitive antibacterial drug to Enterococcus faecalis. Overall, the pulmonary lesion was caused by the detachment of bacterial neoplasm of aortic valve, which has passed through the PDA and entered the pulmonary circulation.

Objective To evaluate the effect of mind-map in health education of elderly patients with knee osteoarthritis in community.Methods 71 elderly patients with knee osteoarthropathy were randomly divided into observation group(n=35)and control group(n=36).The control group received routine oral mode health education,and the observation group applied mind map to health education.Before and after the intervention,the self-designed disease knowledge and compliance questionnaire were used to evaluate the effect of two groups of health education.Results There was no significant difference in score between the two groups(P=0.997).After intervention,the score of disease knowledge questionnaire(20.25±3.01)points in the observation group was higher than(18.17±3.12)points in the control group,the difference was statistically significant(t=2.858,P=0.006).At the 1st,3rd and 6th month,the compliance scores of the observation group were(19.35±3.14)points,(19.68±3.22)points,(20.18±3.42)points,respectively,which of the control group were(17.42±3.11)points,(17.89±3.35)points,(18.32±3.47)points,respectively,the differences between the two groups were statistically significant(t=2.602,2.294,2.274,P=0.011,0.025,0.026).The scores of the observation group questionnaire were all more than 3 points,the difference was statistically significant between the two groups(all P=0.000).Conclusion Using mind map to carry out health education to middle-aged and elderly patients with knee joint disease can help patients master disease knowledge and improve compliance,its effect is better than traditional method.
ABSTRACT
It was developed that a new method for measuring the ratio of pulmonary blood flow tosystemic biood flow by two-dimensional Doppler echocardiography.Qp and Qs blood flow were consid-ered to be propotional to the mitral and tricuspid Doppler flow velocity time integral multipled respectively by mitral or tricuspid valve ring diameters(MVID or TVID),I.e.MVID/TVID was equal to Qp/Qs.With the method,we calculated the Qp/Qs ratio close to 1:1(0.939+/-0.083)in 18 normal Per-sons,0-656+/-0.167 in 15 patients with Tetralogy of Fallot.Qp/Qs in TOF corrected negativly With hemoglobin.Our results demonstrated that conventional Doppler mdthod to calculate the Qp/Os ratio can be simplified.
