What is its epidemiological characteristics and clinical manifestations? As pediatric medical workers,what should we do? The hot issues at present will be discussed in this article.

Clinical data of 150 patients with mild and 38 patients with severe confirmed influenza A/H1N1 were collected and retrospectively analyzed in this paper with descriptive epidemiology. Mild patients mainly presented with symptoms similar to seasonal influenza with few complications, however,persistent high fever, cough with bloody sputum expectoration, chest distress and short of breath manifested in severe patients with respiratory failure and acute respiratory distress syndrome in some cases. Proportion of obesity and underlying diseases in severe patients, who were at high risk for severe influenza A/H1N1, was higher than that in mild ones (P＜0. 05). Average course of the illness spanned five to 11 days in patient with mild influenza A/H1N1 with all cured, and 34 of severe cases discharged with better recovery and other four died with a case-fatality of 10. 5 percent.

BACKGROUND: 6-minute walking test (6MWT) is a submaximal test, characterizing by easily processing and low cost, thus it is widely used in the clinic. However, how to change walking distance into maximal motor capacity needs to be further studied.OBJECTIVE: To study the correlation of 6-minute walking distance (D), work (W), peak oxygen uptake (VO_2 peak) and maximal oxygen uptake (VO_2 max) detected by Bruce.DESIGN, TIME AND SETTING: This study was performed at tshe Department of Rehabilitation Medicine, Zhongda Hospital affiliated to Southeast University from March to May 2009.PARTICIPANTS: A total of 25 healthy volunteers were enrolled, including 14 males and 11 females, with a mean age of (22.0±2.3) years.METHODS: All 25 subjects were tested with cardiopulmonary exercise testing (CPET) according to Bruce, VO_2 max and anaerobic threshold (AT) was detected respectively, then 6MWT" was adopted to detect 6-minute walking distance (D), work (W) and maximal oxygen uptake (VO_2 max) of subjects. Data of pulmonary gas exchange in breathing was detected by wireless remote sensor K4b~2 to obtain VO_2 max and VO_2 peak.MAIN OUTCOME MEASURES: ① Regularity of cardiac rate, oxygen uptake and respiratory frequency varied with time passing; ② Walking distance, work, oxygen uptake, cardiac rate and respiratory frequency were compared before and after testing; ③ Maximal oxygen uptake and anaerobic threshold with CPET were compared to peal oxygen uptake with 6MWT; ④ Correlation of distance, work between maximal oxygen uptake and peal oxygen uptake.RESULTS: There was no significant difference between AT from CPET and VO2 peak from 6MWT (P > 0.05). 6-minute walking distance was not correlated with either VO_2 peak or VO_2 max. However, 6-minute walking work was linearly correlated with both VO2 peak (r=0.779 7, P < 0.001) and VO_2 max (r=0.894 1, P < 0.001).CONCLUSION: 6-minute walking test is an exercise test at level of anaerobic threshold. 6-minute walking work can reflect both submaximal exercise capacity and maximal exercise capacity.

Magnetic resonance imaging has shown its important role in both early diagnosis of Alzheimer's disease and revealing the Alzheimer's disease pathogenesis.Structural magnetic resonance imaging include lineal mesure,volume measure and volume rendered.They can detect the abnormal brain structure,especially the change of mesial temporal lobe(hippocampus,amygdale) in early onset of Alzheimer's disease.Recent studies more focused on functional imaging which can find the functional changes in brain.Prior to structural changes,functional changes happen,so it can reflect the sutile pathological process in Alzheimer's disease.The functional imaging mainly refers to magnetic resonance spectroscopy,functional magnetic resonance imaging,diffusion weighted imaging and diffusion tensor imaging.As developing of these new technologies,we know more and more about pathogenesis and biological characteristics of Alzheimer's disease.

AIM: To investigate whether calcium activated potassium channel(KCa) and mitochondrial permeability transition pore(mPTP) contribute to cardioprotective effect elicited by anoxic postconditioning.METHODS: The isolated perfused hearts of male Sprague-Dawley rats were subjected to 30 min global anoxic followed by 120 min reoxygenation.Formazan content of myocardium was measured at 490 nm spectrophotometrically,and the level of lactate dehydrogenase(LDH) in the coronary effluent was detected.The absorbance of isolated heart mitochondria at 520 nm was determined.RESULTS: Anoxic postconditioning increased formazan content,reduced LDH release,improved the hemodynamic parameters of the left ventricular developed pressure,maximal rise/fall rate of left ventricular pressure,left ventricular end-diastolic pressure and rate pressure product and attenuated the decrease of coronary flow during reperfusion.Pretreatment with paxilline(1 ?mol/L) inhibited the effect of anoxic postconditioning.The opening of mPTP was suppressed in the mitochondria isolated from A/R hearts treated with anoxic postconditioning.CONCLUSION: The findings indicate that in the isolated rat heart,anoxic postconditioning protects myocardium against anoxic/reoxygenation injury via inhibiting KCa and the mPTP opening.
