Objective To study the effect of cardiac troponin T(cTnT)on the prognosis of chronic heart failure in the elderly patients.Methods Serum level of cTnT,and serum activities of creatine kinase (CK)and creatine kinase-MB(CK-MB)were measured in 60 elderly patients of chronic heart failure with varied classes of cardiac function.Cardiac events,including malignant cardiac arrhythemia,repeated or aggravated heart failure or cardiac death,in patients with increased cTnT during hospitalization were compared to those without it.Results Serum level averaged(89.1?13.6)mmol/L for CK and(7.9? 1.4)mmol/L for CK-MB in 20 patients with Class Ⅱ cardiac function by New York Heart Association (NYHA)classification and without increased cTnT,(88.2?13.4)mmol/L for CK and(7.5?1.8) mmol/L for CK-MB in 19 patients with Class Ⅲ cardiac function and four of them with increased cTnT,and (93.3?14.2)mmol/L for CK and(8.1?1.6)mmol/L for CK-MB in 21 patients with Class Ⅳ cardiac function and 14 of them with increased cTnT.Malignant cardiac arrhythemia occurred in six,repeated heart failure in eight,and death in three of 18 patients with increased cTnT,and one,two and one in 22 patients without increased cTnT,respectively.Incidence of cardiac events was higher in patients with increased cTnT than those without it(P

Volatile oil components and the contents and types of amino acid in spica of Prunella vulgaris were analysed by GC-MS and amino acid analyzer. Esters, fatty acids, aromatic hydrocarbon, ketone and several alcohol compounds were identified by mass spectrum comparison. In these ingredients, beta-ionone smelled aroma of cedar, raspberry, nerolidol showed weak sweet soft orange blossom flavor, neroli tasted sweet and fresh, nerolidol tasted sweet with light aroma of wood, hexadecanal showed a weak aroma of flowers and wax, alpha-sinensal had rich and fresh sweet orange flavor. To some extent, these types of aromatic substances can affect the taste of herbal tea or decoction made of Spica Prunellae. Among amino acids detected, natural amino acids accounted for a larger proportion, and those natural amino acids showed bitterness, slight bitterness, sourness (freshness), sweetness, slight sweetness, sourness (slight freshness). The results indicated that bitter and slightly bitter amino acids have the greatest impacts on the sense of Spica Prunellae.

Objective To investigate the nutritional status of elderly inpatients with benign orthopedic diseases and to assess its relationship with clinical outcomes.Methods Nutritional Risk Screening 2002 ( NRS 2002) was used to prospectively investigate undernutrition and nutritional risk in elderly patients hospitalized between April 1 and May 31, 2012 in Beijing Hospital for benign orthopedic diseases.Associations between nu-tritional status and clinical outcomes were analyzed.Results A total of 520 patients were included, with a mean age of (75 ±7.09) years.The mean body mass index (BMI) was (23.20 ±3.83) kg/m2, mean dominant-hand grip strength was (16.87 ±19.19) kg, mean mid-upper arm circumference was (25.62 ±3.81) cm, mean calf circumference was (31.92 ±4.02) cm.Compared with patients aged 65-79 years, patients≥80 years showed significantly lower hand grip strength [ (13.58 ±15.92) kg vs.(18.48 ±20.42) kg, P=0.004].All the pa-tients completed NRS 2002, which showed that 9.31%of the patients had undernutrition (BMI≤18.5 kg/m2), and 45.19%had nutritional risk (NRS 2002 score≥3).Compared with patients aged 65-79 years, patients≥80 years had significantly higher incidence of undernutrition (13.97% vs.7.21%, P=0.024) and nutritional risk (52.38%vs.41.76%, P=0.024), higher incidence of infectious complications in patients with nutritional risk (10.21%vs.5.26%, P=0.044), longer hospital stay [ (11.66 ±5.76) days vs.(10.42 ±4.37) days, P=0.016], and higher hospital expense [(20.28 ±1.811) thousand yuan vs.(16.39 ±1.362) thousand yuan, P=0.016].Conclusion Elderly patients hospitalized for benign orthopedic diseases have a high incidence of undernutrition and nutritional risk, which is associated with worse clinical outcomes.

Objective To detect plasma amino-terminal pro-brain natriuretic peptide (NT-ProBNP) ,D-Dimer levels in the pa-tients with acute pulmonary embolism (APE) in order to investigate their change characteristics and significance .Methods Among 60 patients with suspected APE ,40 cases diagnosed by CT and meeting the thrombolytic condition were set as the experimental group and other 20 cases of excluded APE by CT as the control group .Plasma NT-ProBNP and D-dimer before treatment in the two groups and after 2-week thrombolytic therapy in the experimental thrombolysis were detected and compared .Results The diagnos-tic sensitivity of NT-ProBNP for early APE was 92 .3% and the specificity was 65% ,while the diagnostic sensitivity of D-dimer for early APE was 100% and the specificity was 70% ;the plasma NT-ProBNP and D-dimer levels before thrombolysis in the experi-mental group were significantly higher than those in the control group with statistical differences (P<0 .01) .Conclusion Plasma NT-ProBNP and D-dimer has important clinical significance for APE and can provide the basis for the early diagnosis and the cura-tive effect observation of the patients with APE .

Objective To explore the interaction between serum melatonin and the status of disease and probe the effect factor of serum melatonin change in asthmatic children.Methods Serum melatonin was measured in asthmatic children with 15 cases of mild persistent asthma,15 cases of moderate persistent asthma,15 cases of severe persistent asthma,15 cases of stable asthma and 15 cases of normal subjects by enzyme-linked immunosorbent assay(ELISA).Results The levels of serum melatonin in the 5 groups of mild persistent asthma,moderate presistent asthma,Severe Persistent asthma,Stable asthma,control subject were(22.76?5.16)ng/L,(16.79?3.35)ng/L,(11.54?1.45)ng/L,(22.06?3.36)ng/L,(28.72?4.32)ng/L,respectively.There were significant differences between any of them(Pa

OBJECTIVETo analyze the computed tomography (CT) and magnetic resonance imaging (MRI) findings of small hepatocellular carcinoma to improve the accuracy in the diagnosis.

METHODSThis retrospective analysis involved 41 patients with small hepatocellular carcinoma cases confirmed by pathological examination of the biopsy samples or follow-up. These patients were assessed for CT and MRI findings including lesion size, density or signal intensity, enhancement patterns, and presence of tumor capsules.

RESULTSOn unenhanced CT images, small hepatocellular carcinomas were displayed mainly as low-density masses, and the majority of tumors presented with low signal intensity on T1-weighted unenhanced MR images with increased signal intensity on T2-weighted images in comparison with the surrounding liver parenchyma. Most of tumors showed intense enhancement during the arterial phase (CT in 15 cases and MRI in 13 cases), but some appeared isointense to the liver parenchyma (CT in 4 cases and MRI in 4 cases). In portal and delayed phases, the tumors typically had lower signal intensity than that of the surrounding liver tissues (CT in 25 cases and MRI in 12 cases) with enhancement of the tumor capsules (13 cases).

CONCLUSIONDynamic enhanced scanning can be more informative of the pathology and blood supply of small hepatocellular carcinoma. Early and late arterial phase imaging may help in detecting the small lesions and in making differential diagnosis.
