OBJECTIVETo analysis the risk factors predicting intracardial thrombus after prosthetic valve replacement.
METHODSThe clinical data of 29 cases from January 2005 to April 2009 with intracardial thrombus after prosthetic valve replacement during a 1-year follow-up was retrospectively analyzed. There were 11 male and 18 female, aged from 12 to 70 years with a mean of 48 years. The risk factors of intracardial thrombus were examined by univariate and multivariate analysis.
RESULTSUnivariate analysis found that bioprosthetic valve replacement, anticoagulation using aspirin, valve replacement at mitral position, atrial fibrillation, preoperative and postoperative internal diameter of left atrium, postoperative fibrinogen were predict factors of intracardial thrombus after prosthetic valve replacement (P < 0.05). Logistic regression analysis showed valve replacement at mitral position (OR = 9.815, P < 0.05), atrial fibrillation (OR = 5.267, P < 0.05), preoperative internal diameter of left atrium (OR = 4.529, P < 0.05) were significant risk factors of intracardial thrombus after prosthetic valve replacement.
CONCLUSIONSValve replacement at mitral position, atrial fibrillation, and preoperative internal diameter of left atrium are the correlated risk factors of intracardial thrombus after prosthetic valve replacement. Anticoagulation after prosthetic valve (especially bioprosthetic valve) replacement should be standardized to prevent intracardial thrombus formation.

OBJECTIVETo analyze clinical features of pediatric rhino-source diseases for reducing missed diagnosis and misdiagnosis.
METHODData of 3588 children with rhino-source diseases seen from April 2005 to May 2006 were retrospectively analyzed in this study in order to disclose the relationship of etiological factor, clinical features and diagnosis.
RESULTAmong all these cases, 2090 complained of nasal discomfort including nasal obstruction, discharge, rhinalgia and epistaxis. However 1498 cases (41.76%) did not, of whom 470 cases had snoring and apnea, 332 cases of otalgia and otorrhea, 145 cases had chronic cough, 138 had headache and 92 had lower respiratory infection.
CONCLUSIONA high percentage of children who suffered from pediatric rhino-source disease did not develop nasal symptoms. Pediatric rhino-source disease should be considered for patients in whom the therapeutic effect is unexpectedly poor.

OBJECTIVETo analysis the causes of valve prosthesis-patient mismatch (PPM) after mitral valve replacement in Chinese patients.
METHODSConsecutive 100 patients for elective mitral valve replacement from January 2009 to June 2009 were enrolled and followed for this study. There were 37 males and 63 females. The mean age at operation was (52 ± 9) years (ranging 32 to 76 years). The predominant mitral valve lesion was stenosis in 60 patients, regurgitation in 14 patients and mixed in 26 patients. Among them, 63 patients were combined tricuspid valve regurgitation. Mitral valve effective orifice area was measured by Doppler echocardiography in 100 patients who received mitral valve replacement and indexed for body surface area (EOAI). PPM was defined as not clinically significant if the EOAI was above 1.2 cm(2)/m(2), as moderate if it was >0.9 and ≤ 1.2 cm(2)/m(2), and as severe if it was ≤ 0.9 cm(2)/m(2). By using the criteria, all 100 patients were classified to two groups: PPM group and no PPM group. The clinical characteristic of the patients between the two groups was compared to determine the causes of PPM and the predictors of outcomes after mitral valve replacement, such as the gender, age, valve prosthesis type, size, body surface area, and mitral valve lesion, et al.
RESULTSOf the 100 patients after MVR, 52 (52.0%) had significant PPM, 51 (51.0%) had moderate PPM, and 1 (1.0%) had severe PPM. In comparison to patients in no PPM group, patients in PPM group had a significantly larger body surface area [(1.76 ± 0.17) m(2) vs. (1.59 ± 0.13) m(2), P < 0.01] and higher prevalence of male gender (55.8% vs. 16.6%, P < 0.01). The other preoperative and operative data were similar in both groups, such as the valve prosthesis type, size, and mitral valve lesion, et al. There were no significant differences in postoperative Doppler-echocardiographic data of cardiac structure and heart function between the two groups (P > 0.05).
CONCLUSIONSThe higher incidence of PPM in mitral valve position was in male or large body surface area patients. At the time of operation, surgeons should consider the related factors, such as the patient's gender and body surface area, et al. A larger prosthesis size might be implanted to avoid PPM in mitral valve position.

OBJECTIVETo evaluate intraventricular mechanical synchrony in systole by real-time tri-plane tissue synchronization imaging (TSI).
METHODSReal-time tri-plane TSI was performed in 20 normal subjects, and the apical 4-chamber, 2-chamber and long-axis views of the left ventricular (LV) were obtained simultaneously. The data were post-processed offline, and a TSI surface map of LV colorized according to the time-to-positive peak systolic velocity (TTP) was generated to reflect the segment TTP semi-quantitatively. The segmental TTP of the six-basal and six-mid segments of LV was measured and compared.
RESULTSThe myocardium was color-coded mainly by well-distributed green, and only a small portion displayed yellow or red color in the apical area; the TTP showed no significant differences between the segments measured (P>0.05).
CONCLUSIONSIn normal subjects, the long-axis systolic motions of the LV are highly synchronized. TSI allows immediate visual identification of intraventricular mechanical synchrony and quantitative measurement of regional TTP.

OBJECTIVETo investigate the long-term outcomes of off-pump coronary artery bypass grafting (OPCAB) in patients aged over 75 years and analyze the risk factors affecting the outcomes of the procedure.
METHODSClinical data were reviewed for 97 consecutive patients aged 75 years or above receiving OPCAB at our center between November, 2000 and November, 2013. The perioperative data including length of ICU stay, duration of mechanical ventilation, incidence of postoperative complications and mortality rate of the patients were analyzed. The follow-up data of the patients were also analyzed including all-cause mortality rate and major adverse cardiac and cerebral events (MACCE, including myocardial infarction, cerebrovascular event, and repeated revascularization).
RESULTSThe perioperative mortality rate was 3.09% (3/97) in these patients. Of the 97 patients analyzed, 91 (93%) were available for follow-up for 29-192 months (with a median of 95.61∓34.07 months). The 10-year survival rate of the patients was 62% with a 10-year MACCE-free survival rate of 47.4%. During the follow-up, 6 (6.8%) patients underwent repeated revascularization procedures, 12 (12.37%) had cerebrovascular accidents and 5 (5.15%) had myocardial infarction. Logistic regression analysis showed that hypertension (OR=1.388, P=0.043) and diabetes (OR=1.692, P=0.017) were independent predictors of MACCE, and incomplete revascularization did not increase the risk of postoperative MACCE.
CONCLUSIONOPCAB is safe and effective in elderly patients with good long-term outcomes. Hypertension and diabetes are independent risk factors of MACCE, and adequate control of blood pressure and blood glucose can reduce the incidence of postoperative MACCE. Incomplete revascularization is not detrimental to the long-term outcomes of OPCAB in elderly patients.

Objective To disclose the etiological factors and to investigate the therapeutical effect on nasal disorders in 128 children with intractable cough. Methods One hundred and twenty-eight children with intractable cough were consulted by ENT doctors using electronic nasopharyngoscope, for those children with nasal diseases, relevant treatment was given. Results Among 128 children, one hundred and sixteen had nasal disorders. Upper airway cough syndrome (UACS) was diagnosed in 92 cases(71.9% ), nasal disorders without UACS was diagnosed in 24 cases(18.7%) ,no nasal disorders were found in 12 cases (9.4% ). Among children with UACS, allergic rhinitis was diagnosed in 76 cases, rhino-sinusitis in 39 cases,adenoid hypertrophy in 54 cases, and chronic rhinitis in 8 cases. However, for those children without UACS, 10 cases had chronic rhinitis and 14 cases had allergic rhinitis. Clinical symptoms, signs and the findings of electronic nasopharyngescope were analyzed in 92 children with UACS. The results showed that regular cough occurred in 62 cases, nasal disease in 65 cases, subjective feeling of postnasal discharge in 18 cases, mouse breathing or snoring in 32 cases, purulent secretion in nasal meatus in 61 cases,retropharyngeal folliculosis in 58 cases, purulent secretion in pharynges detected from pharynx in 41 cases,and purulent or viscosity secretion were found in 91 cases by first electronic nasopharyngoscopy. After 14 days of treatment, the children with UACS (90/92) had significant higher remission rate (χ~2=32.21 ,P=0.000) in cough than those who had nasal disorders but without UACS (13/24). Conclusions The nasal disorders, especially for UACS, were common in children with intractable cough. The therapy to nasal disorders could release the chronic cough symptoms in children with intractable cough.

OBJECTIVETo explore the effect of T(3) on the expression of transferrin receptor (TfR) and ferritin (Fn) in K562 cells and its possible mechanism.
METHODSFlow cytometry was used for the detection of TfR expression, radioimmunoassay for Fn expression, RNA/protein band shift assay for the binding activity of iron regulatory protein (IRP) and iron responsive elements (IRE), and RT-PCR for TfR and Fn mRNA levels.
RESULTSDifferent concentration of T(3) significantly increased Fn expression of K562 cells, especially at 100 nmol/L and 200 nmol/L (p < 0.05). However, T(3) had no effect on TfR expression. T(3) decreased the binding activity between IRP and IRE, particularly at concentration of 50 nmol/L. Different concentration of T(3) increased Fn-H mRNA level at different time point while it had no effect on TfR mRNA level.
CONCLUSIONT(3) increased Fn expression of K562 cells through the possible mechanisms of either the post-transcriptional regulation or transcriptional modulation.

OBJECTIVETo analyze the effects of perioperative intra-aortic balloon pump (IABP) support in EuroSCORE high-risk patients undergoing cardiac surgery, and evaluate the risk factors associated with mortality and midterm survival.
METHODSFifty-eight patients with EuroSCORE of no less than 6 underwent cardiac surgery and received peri-operative IABP support, including 29 with preoperative IABP support, 21 with intra-operative IABP support, and 8 with postoperative IABP support. The patients who survived the surgeries were followed up for at least 1 year.
RESULTSComplications related to IABP support occurred in 2 cases (3.45%). The in-hospital mortality was 6.89% (4/58) in this series. Patients with intra-operative IABP had a lower ejection fraction, and those with pre-operative IABP showed more frequent unstable angina and recent myocardial infarction. The number of emergency procedures was also significantly higher in patients with pre-operative IABP support. Patients with intra- or postoperative IABP support had a longer ICU stay. The 1-year follow-up was completed in 54 patients and 4 deaths were recorded, with a 1-year survival of 86.21%. The 1-year survival rate was significantly higher in patients with preo- and intra-operative IABP support than those with post-operative IABP.
CONCLUSIONPeri-operative IABP support benefit cardiac support for cardiac surgery, and its preoperative use does not increase the surgical risk. Early prophylactic IABP support according to the EuroSCORE can improve the outcome of the high-risk cardiac surgery.
