Objective: To explore change of hemoglobin (Hb) concentration, the relationship between anemia and left ventricular function and the influence of anemia on prognosis in patients with diastolic heart failure (DHF). Methods: According to NYHA classification, a total of 176 DHF patients were divided into class Ⅱ group (n=78), class Ⅲ group (n=50) and class Ⅳ group (n=48), then Hb level and morbidity rate of anemia were analyzed in each group. According to diagnostic standard of anemia, patients were divided into anemia group (n=58, , occupied 33.0%) and non anemia group (n=118, occupied 67.0% ). Left ventricular diastolic function, mortality rate and rehospitalization rate during follow-up were compared and analyzed between two groups. Results: Along with cardiac function class rose (from class Ⅱ to class Ⅳ), Hb level showed a decreasing trend [(130±6) g/L vs. (108±4) g/L vs. (96±12) g/L], while morbidity rate of anemia gradually rose (8.97% vs. 36.0% vs. 68.8%), P<0.05 all in anemia group；Compared with non-anemia group, there were significant rise in percentages of patients with coronary heart disease (55.1% vs. 65.5%), levels of creatinine [(87.6±39.2) μmol/L vs. (113.7±59.8) μmol/L] and N terminal pro B type natriuretic peptide [NT-proBNP, (578.0±136.7) pg/ml vs. (886.0±174.8) pg/ml], and early-diastolic peak velocity deceleration time [(137±15)ms vs. (196±13)ms], and significant reduction in mitral early/late diastolic peak flow velocity [E/A, (0.87±0.32) vs. (0.62±0.29)], P<0.05 all. Compared with non-anemia group, there were significant rise in mortality rate (9.3% vs. 20.7%) and rehospitalization rate (18.6% vs. 32.8%) in anemia group during follow-up, P<0.05 all. Conclusion: DHF patients often complicate with anemia. Along with heart failure aggravates, their morbidity rate of anemia rises, and anemia may aggravate cardiac diastolic dysfunction. Mortality rate and rehospitalization rate rise in DHF patients complicated with anemia.

Objective To examine the consistency between asthma children's self-assessment health-related quality of life and their proxies' assessment, to give theoretic basis of clinical treatment for asthma children. Methods Parents and asthma children completed the PedsQLTM 4.0 Generic Core Scales and PedsQLTM 3.0 Asthma Module during an outpatient visit or in the hospital. Wilcoxon signed rank test and ICC were used to compare the difference between asthma children's self-report and their proxies' report. Results The findings indicated that neither the total scores nor domain scores (except physiological domain) between asthma children's self-reports and proxies' reports (parents most of all)showed inconsistency. The value of ICC was not less than 0.7 except physiological dimension and showed consistency. Some different information in several domains was founded by the scores after layered by age. Conclusions There are consistency between children's self assessment of health-related quality of life and their proxies' assessment based upon results of PedsQLTM scale.

OBJECTIVE: To explore the difference of the threshold of auditory steady-state evoked responses (ASSR) in awake and sleeping. METHOD: Fifteen adults (30 ears) with normal hearing were selected to ASSR test. ASSR parameters: carrier frequency (CM)are 0.5, 1.0, 2.0, 3.0, 4.0, 6.0 kHz, modulation frequency (FM) are 46.81 Hz. The test was performed in two different status (in awake and sleeping). RESULT: In awake, the thresholds of ASSR with FM of 46 Hz are significantly lower than 81 Hz (P < 0.01); In sleeping, the thresholds of ASSR with FM of 81 Hz are lower than 46 Hz above 2 kHz CM (P < 0.05), which thresholds were close to pure tone. CONCLUSION To select low modulate (46 Hz) frequency in awake, and use high modulate (81 Hz) frequency in sleeping. When perform ASSR test, the test values are closer to the actual hearing threshold.
