OBJECTIVETo explore the cognitive function status and potential influence factors on cognitive function in hospitalized patients with chronic heart failure.

METHODSUsing a cross-sectional research design, CHF patients (n = 267, mean age (63.8 ± 9.4) years) were recruited from two care units-Heart Failure Care Unit and Intensive Care Unit of our hospital. Cognitive function status was evaluated by the Montreal Cognitive Assessment (MoCA) screen test.

RESULTSBased on the MoCA score, 37.8% (101/267) patients suffered from cognitive impairment (score<26), especially on the three specific cognitive functions-memory, langue and executive capability. Multifactorial analysis showed that after controlling for other factors, there was a downward trend on cognitive function with aging (OR = 1.09, 95%CI:1.05-1.14) while higher left ventricular ejection fraction (LVEF) was related to better cognitive function (OR = 0.97, 95%CI:0.95-0.99); patients who took medicine regularly also had better cognitive function (OR = 3.71, 95%CI:1.40-10.91); cognitive function was better in patients with high level of social support compared those with low social support (OR = 0.92, 95%CI:0.88-0.96).

CONCLUSIONSIncidence of cognitive impairment is high in hospitalized patients with chronic heart failure. Age, LVEF, whether taking medication regularly and social support are factors related to cognitive function in CHF patients.

Objective The 18F-ML-10 PET/CT apoptosis imaging was taken in the early Parkinson's disease (PD) rat models.The feasibility of diagnosis of PD with 18F-ML-10 PET/CT apoptosis imaging is explored.Methods Twenty adult healthy male Sprague-Dawley rats were randomly divided into control group and PD model group (n=l 0).Intrastriat administration of 6-hydroxy dopamine (6-OHDA) was performed to induce progressive and retrograde degenerative changes in the substantial nigra of neurons (PD models).One week after apomorphine inducement,the rotational behaviors of the rats were evaluated.~C-CFT PET/CT imaging and 18F-ML-10 PET/CT were performed to observe the dopamine transport protein expression in the corpus striatum and apoptosis of dopaminergic neurons in the substantia nigra.Immunofluorescence staining of anti-tyrosine hydroxylase (TH) antibody was performed to evaluate the survival of dopaminergic cells in the compact part of substantia nigra.TUNEL was performed to evaluate the apoptosis of dopaminergic cells in the compact part of substantia nigra.Nissl staining was performed to detect the cellular morphology.Results One week after PD modeling,the rats in the experimental group obviously rotated to the contralateral,and the average rotation speed was (4.52 ±1.03) r/min.The ratio of 11C-CFT between the right and left striatum of rats in the experimental group was 0.556±0.017,which was significantly lower than that of the control group (0.998±0.013,P＜0.05).The radioactivity ratio of'8F-ML-10 between the right and left substantia nigra of rats was 1.722±0.083,which was significantly higher than that of the control group (1.024±0.056,P＜0.05).Immunofluorescence showed that the ratio of TH-positive neurons between the right and left compact part of substantia nigra in rats of the experimental group was 0.528 ±0.012,which was significantly lower than that of the control group (1.036±0.030,P＜0.05).TUNEL showed that the number of dopaminergic neuronal apoptosis in the experimental group was 43.200±2.507,which was significantly larger than that of the control group (1.400±0.427,P＜0.05).Conclusion PD is associated with apoptosis of dopaminergic neurons;18F-ML-10 PET/CT imaging can be used to diagnose PD in the early-stage.

OBJECTIVETo investigate the plasma level of amino-terminal pro-brain natriuretic peptide (NT-proBNP) and related influencing factors in a community-based healthy population in Beijing area.

METHODSWe measured plasma NT-proBNP level by fluoroimmunoassay between March 2012 and July 2012 from 1 034 healthy subjects (including 486 men and 548 women). Empiric method was used to determine the reference value and influencing factors were analyzed.

RESULTSAge and gender are important factors affecting the level of NT-proBNP in healthy subjects. NT-proBNP plasma level is significantly higher in women than in men within each age strata below 75 years old, i.e. < 45, 45-54, 55-64 and 65-74 years old (P = 0.005, 0.001, 0.001, 0.011 respectively), but NT-proBNP plasma level is similar between male and female older than 75 years (P = 0.504). NT-proBNP level also increases with age irrespective of gender. Body mass index (BMI) is another independent influencing factor of NT-proBNP (P < 0.001), while estimated glomerular filtration rate is not influencing factor. The reference range of NT-proBNP is < 133 ng/L for men and < 289 ng/L for women aged < 55 years old, < 185 ng/L for men and < 333 ng/L for women aged between 55 and 64 years old, and < 465 ng/L for men and < 378 ng/L for women aged ≥ 75 years old.

CONCLUSIONThe major influencing factors of NT-proBNP level in the healthy population are age, gender and BMI. It essential to establish normal reference range of NT-proBNP according to these factors for Chinese population.

OBJECTIVETo explore the predict value of plasma soluble ST2 (sST2) on one-year mortality for hospitalized patients with chronic heart failure (HF).

METHODSA total of 1 244 consecutive hospitalized patients admitted to Heart Failure Center Fuwai Hospital between March 2009 and July 2012 and with HF as their primary diagnosis were included. Plasma sST2 was measured in all patients and patients were followed up for 1 year, and the primary endpoint was defined as all-cause death.

RESULTSThere were 193 deaths during follow up. sST2 concentrations at admission were positively correlated with NT-proBNP, NYHA functional class and heart rate, and negatively correlated with left ventricular ejection fraction, blood sodium, total cholesterol and glomerular filtration rate at admission. sST2 concentrations were significantly higher in non-survivors compared with survivors (P < 0.001). Multivariable Cox regression analyses showed that sST2 independently predicted 1-year mortality (per 1 log unit, hazard ratio 1.87, 95% confidence interval: 1.56 to 2.25, P < 0.001). In receiver operating characteristic analyses, the area under the curve for ST2 was 0.776 which was similar to that of N-terminal pro-B-type natriuretic peptide (NT-proBNP) (AUC = 0.775). The prognostic value was improved when combining these two biomarkers together (AUC = 0.813).

CONCLUSIONSsST2 concentration at admission is correlated with clinical and biochemical indexes and associated with 1-year mortality for hospitalized patients with HF.

Objectives: To study an effects on hearing ability and speech performance of the patients with auditory neuropathy (AN) after cochlear implantation (CI). Methods: Thirty-five AN patients (26 males and 9 females) after CI in our center since 2007 were chosen, including 5 postlingual patients (implanted age from 14.3 to 38.6 years old) and 30 prelingual patients (implanted age from 1.1 to 13.7 years old). Hearing sensitivity and speech performance were estimated via following methods: (1) implanted hearing thresholds by sound field audiometry; (2) speech audiometry, including monosyllable, disyllable and sentences recognition test by computer-controlled software and sentence recognition test under noise condition (signal to noise ratio=+ 10dB); (3) Mandarin Early Speech Perception test (MESP), Mandarin Pediatric Speech Intelligibility test (MPSI), MAIS, or IT-MAIS for prelingual AN implantees. Results: The average implanted hearing threshold (250-4 000 Hz) was (41.1±11.7) dBHL in 22 AN implantees, while those prelingual implantees was (39.1±10.9) dBHL, and (44.9±12.3) dBHL in postlingual implantees. Speech audiometry were implemented in four of 5 postlingual AN implantees, the results showed increasing tendency in monosyllable recognition scores, dramatic individual variation in computer-controlled disyllable and sentences recognition test, and poor scores (<30%) in speech recognition test in noise condition. Four of 30 prelingual implantees reconstruct their speech recognition ability within 1-3 years after switch-on, characterized as recognition scores (>60%) in monosyllable, disyllable and sentences. The one of prelingual implantee gained recognition scores of speech in noise within 1 year after switch-on. MAIS or IT-MAIS were implemented in twenty-five prelingual implantees, the average score in these patients was 28.6±11.7. Conclusion Cochlear implant can improve the hearing thresholds of AN patients, however, the improvement in speech performance presented significant variations among the implanted individuals.
