Objective To discuss the effect of continuing nursing care on patients with rheumatoid arthritis. Methods 117 patients with rheumatoid arthritis were divided into the control group (60 pa-tients) and the experimental group(57 patients). The control group adopted clinic follow-up visit and rou-tine responding measures. The experimental group was given knowledge education according to the ASMP course, which included demonstration,nurse-patient communication,communication between patients, video show, telephone follow-up and support, etc. The degree of pain,cognition degree of disease knowledge, fre-quency of physical exercises,compliance with doctor's advice, readmission rate and self-care ability of pa-tients with joint deformity were compared by χ2 test between the two groups. Results The experimental group was superior to the control group in the following aspects, such as degree of pain,cognition degree of disease knowledge, frequency of physical exercises,compliance with doctor's advice, readmission rate and self-care ability. Conclusions Application of continuing nursing care in patients with rheumatoid arthri-tis contribute to the prognosis of patients.

Objective To assess the efficacy of cardiac resynchronization therapy (CRT) using real-time three-dimen?sional echocardiography (RT-3DE) and speckle tracking imaging (STI) in patients with heart failure. Methods Thirty-one patients with chronic heart failure were examined by RT-3DE and STI before CRT and 3, 6 months after CRT. The values of left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were measured. RT-3DE was used to evaluate the minimum regional volume for 16 segments (Tmsv-16SD) and the ratio of Tmsv16SD to R-R interval, and the maximum time difference (Tmsv-16Dif). STl was used to evaluate the ratios of standard deviation of the time to peak longitudinal radial and circumferential strain to R-R interval (Tls-16SD%, Trs-16SD%,Tcs-16SD%) from the beginning of Q wave of electrocardiography to the point minimal systolic volume of all 16 segments and the maximum time difference. Results The values of LVEDV and LVESV were smaller 3 and 6 months after CRT than those before CRT. The value of LVEF was significantly improved after CRT (P < 0.05). The values of Tmsv-16SD%, Tmsv-16Dif%, Tls-16SD%, Trs-16SD%, Tcs-16SD%and T-Dif%were gradually decreased after CRT (P<0.05). The values of Tmsv-16SD%, Tmsv-16Dif%,Trs-16SD%and Tcs-16SD%were negatively related with LVEF (r=-0.79,-0.82,-0.69 and-0.74(P<0.05). The better consistency was found between RT-3DE and STI methods(Kappa=0.77). Conclusion Re?al-time three-dimensional echocardiography and speckle tracking imaging can provide more accurate quantitative informa?tion of cardiac resynchronization therapy for assessment of treatment and prognosis in patients with heart failure.

Objective To investigate the diagnostic value of preoperative real-time three-dimensional color Doppler transthoracic echocardiography on assessment of patients with structural heart disease (SHD). Methods A total of 111 pa?tients were assessed preoperatively using real-time three-dimensional color Doppler transthoracic echocardiography (RT-3D-CDTTE), which include 31 SHD patients and 80 patients without SHD that were designed as negative control. Conven?tional two-dimensional color Doppler transthoracic echocardiography (2D-CDTTE) were used to compared with RT-3D-CDTTE while cardiovascular angiography and intraoperative findings were used as“Golden Standard”simultaneously. First of all, preoperative echocardiographic examination were performed and diagnosis was given. Angiography and intraoperative findings were hired to verify the accuracy of echocardiographic diagnosis before operation. Results (1) The preoperative RT-3D-CDTTE displayed three-dimensional structure and hemodynamic status of SHD cardiac lesions clearly, which were consistent with cardiovascular angiography and intraoperative findings. (2) P value of McNemar test between 2D-CDTTE and“Golden Standard”was greater than 0.05, Kappa=0.654 (P<0.001). P value of McNemar test between RT-3D-CDTTE and“Golden Standard”was greater than 0.05, Kappa=0.932 (P<0.001). Conclusion RT-3D-CDTTE can provides essen?tial information for preoperative evaluation which is important for decision of SHD management.

Objective To investigate the diagnosis and treatment in patients with acute myocardial infarction (AMI) and complicated left ventricular wall rupture (LVWR). Methods A retrospective analysis was made on the clinical features, diagnosis and successful treatment in three AMI patients with LVWR from December 2015 to April 2016. Results Three cases were included in this study. Case 1, the mesh like cardiac rupture after AMI was diagnosed by ultrasonic Doppler. Emergency revascularization was performed due to the combined cardiac shock, and the infarct related artery was opened. The vasoactive drugs were used after revascularization to reduce ventricular pressure load and volume load in the haemodynamic monitoring, and anticoagulation, antiplatelet agents were less used or discontinued to promote local thrombus healing of ventricular rupture. Case 2 was a recurrent myocardial infarction patient. LVWR was diagnosed by ultrasonic Doppler one day after emergency operation. The ruptured ventricular wall was encapsulated by thrombus. The drug therapy was effective in hemodynamic monitoring. LVWR was further confirmed by cardiac CT after clinical stabilization. Case 3 was diagnosed LVWR by ultrasonic Doppler four days after AMI. Because the ruptured ventricular wall was limited by incompletely organized thrombus, and the haemodynamic condition was stable, selective surgical repair of rupture after coronary angiography was performed. Conclusion The effective drug therapy combined with percutaneous coronary intervention and surgical repair can reduce the risk of death in patients with LVWR after AMI.

ObjectiveTo study the biological characterization and the genetic background of circulating CA16 strains in mainland of China for the purpose of CA16 vaccine development in the future.MethodsCA16 strains were isolated from throat swabs of patients with hand-foot-mouth disease and identified by neutralization assay and RT-PCR.The genotype of these isolates were determined by sequence alignment and phylogenetic analysis of VP1 gene.The proliferation dynamics and the plaque morphology were observed when propagated in Vero cells.The pathogenicity of these CA16 isolates was evaluated by challenging newborn mice.ResultsIn this study,six CA16 circulating isolates,BJ-1-6 were obtained.The RT-PCR products were 150 bp amplified with the general enterovirus primers and 210 bp with CA16 primers respectively,which cannot be amplified by EV71 primers.Additionally,these isolates were identified to display some obvious proliferation dynamics and plaque morphology when propagated for 96 h in Vero cells.The diameter of plaques were about 1.5 to 2 mm for BJ-1,BJ-2,BJ-4,BJ-6,4-5 mm for BJ-3 and 3 mm for BJ5,the plaques were regular except BJ-3.All the six isolates can be neutralized by the convalescent serum of patient infected with CA16.The virus titer of different isolates propagated for five passages in Vero cells was 7.0LgCCID50/ml.The sequence alignment of VP1 gene demonstrated that the genotypes of BJ-2,BJ-4,BJ5 were C1 and BJ-1,BJ-3,B J-6 were C,3 comparatively.The genetic distance of the VPI gene from theseisolates suggested that they were highly genetic identity with the homology of 90％ in nucleotide and 99％ in dedicated amino acid respectively.However,a distinctive difference in pathogenic ability in neonatal mice was found that the suckling mice challenged with BJ-3 & BJ-5 were paralyzed 4-5 d and dead 6-7d postchallenge,compared with the control group without any abnormality in the during of 14 d.ConclusionThe circulating CA16 isolates in China have different biological characteristics,different pathogenic ability and similar genetic backgrounds,which is helpful for the development of a CA16 vaccine in the future.

Objective:To evaluate the effect of propofol on right ventricular hypertrophy induced by pulmonary arterial hypertension (PAH) in rats.Methods:Twenty-two clean-grade healthy adult male Wistar rats, weighing 250-280 g, were divided into 3 groups using a random number table method: control group (group C, n=8), PAH group (group PH, n=6) and propofol group (group P, n=8). In PH and P groups, monocrotaline 60 mg/kg was injected intraperitoneally to establish the model of PAH, while the equal volume of normal saline was administered in group C. Propofol 100 mg/kg was injected intraperitoneally twice a week for 6 consecutive weeks starting from 2 weeks after establishment of the model in group P. The weight of rats was measured before establishment of model and after administration, and the weight difference (△BW=weight after administration-weight before administration) was calculated.At the end of administration, the right ventricular end-diastolic dimension (RVEDD), right ventricular wall thickness in diastole (RVWTd), intraventricular septum in diastole (IVSd), left ventricular posterior wall in diastole (LVPWd) and maximal velocity of pulmonic valve (PV) were measured using cardiac ultrasound.The animals were then sacrificed, and the lungs and hearts were removed for examination of the pathological changes (after haematoxylin and eosin staining) and for determination of the degree of myocardial fibrosis in right ventricular (by Masson staining), expression of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in lung tissues and myocardial tissues of the right ventricle (by immunohistochemistry). Results:Compared with group C, △BW and PV were significantly decreased, RVWTd, IVTd and RVEDD were increased, the thickness of the wall of pulmonary arterioles and myocardial cell penetration area in right ventricular were increased, the expression of IL-6 and TNF-α in lung tissues and myocardial tissues of right ventricle was up-regulated ( P<0.05 or 0.01), inflammatory cell infiltration and structural disorders were found in lung tissues, and intercellular spaces were widened, and the myocardial tissue was extensively fibrotic in group PH.Compared with group PH, △BW and PV were significantly increased, RVWTd, IVTd and RVEDD were decreased, the thickness of the wall of pulmonary arterioles and myocardial cell penetration area (the area of cardiomyocytes in which the nucleus located in the middle) were decreased, the expression of IL-6 and TNF-α in lung tissues and myocardial tissues of right ventricle was down-regulated ( P<0.05 or 0.01), inflammatory cell infiltration, structural disorders, intercellular spaces and degree of fibrosis were improved in group P. Conclusion:Propofol can alleviate right ventricular hypertrophy induced by PAH, and the mechanism is probably related to reduction of inflammatory responses in rats.
