2.Congenital cystic lung lesions
Journal of Clinical Pediatrics 2010;(3):292-294
Congenital cystic lung lesions are a group of congenital lung diseases with low incidence. These include congenital cystic adenomatoid malformation,bronchogenic cyst,congenital lobar emphysema and pulmonary sequestration. These malformations occur during the period of lung development stimulated by various factors. Manifestations of the diseases are very similar,but the pathogenesis and pathology are very different. Congenital cystic adenomatoid malformations are thought to be the results of the cessation of bronchiolar maturation with overgrowth of mesenchymal elements and without development of alveoli. There are 5 pathological types of congenital cystic adenomatoid malformations. Bronchogenic cysts are the results of abnormal budding from a segment of the tracheobronchial tree during embryo development,and the buds with no communication with normal tracheobronchial tree. Congenital lobar emphysema is a term reserved for hyperinflation of alveoli from idiopathic reasons or extrinsic compression,as well as pathological changes of the bronchial wall. Pulmonary sequestrations account for parts of nonfunctioning lung tissue that mostly do not communicate with normal bronchoalveolar tree and vascularized by a systemic artery,two types(intralobar and extralobar sequestration)are described.

Objective To study the regulatory role of chemerin in infant with respiratory syncytial virus (RSV) pneumonia by investigating the level of serum chemerin,pro-inlfammatory cytokine (TNF-α, IL-17), and anti-inlfammatory cytokine (IL-10, TGF-β). Methods The serum level of chemerin,TNF-α,IL-1,IL-10,TGF-βwere tested in 82 RSV pneumonia inpatients (17 severe RSV pneumonia cases,65 mild cases) and 40 controls by ELISA and the severity of the RSV pneumonia was evaluated using a scoring system. Results The serum level of chemerin of RSV pneumonia cases were (610.45±106.63pg/ml) which were signiifcantly higher than the control(337.24±43.37 pg/ml). Chemerin level of severe RSV pneumonia group is signiifcantly higher than mild cases as well [(786.62±82.59 pg/ml)vs (539.98±65.86 pg/ml)P<0.01 ]. Signiifcant positive correlations were found be-tween serum chemerin level and TNF-α,IL-17 level (r=0.81,r=0.61;P<0.01) while the serum level of chemerin is negatively correlated with IL-10, TGF-β(r=-0.80,r=-0.75;P<0.01). Conclusions The level of chemerin increased in RSV pneumonia patients,and related to clinical severity after RSV infection. These results indicate that chemerin may play an important role in the pathogenesis of RSV pneumonia and to the severity of the infection.

Objective To investigate the application value of free plasma metanephrines metanephrine(MN) and normetanephrine (NM) measured with enzyme immunoassay (EIA), NM in diagnosis of pheochromocytoma. Methods Histologically confirmed pheochromocytomas (n=30) and control patients with hypertension (n=51) were enrolled in the study. Blood tests for free plasma metanephrines(MN and NM) were performed with a commercially available EIA kit and the results were compared with [3] I-metaiedobenzyl guanidine (MIBG) whole body scan findings. Results The whole body scan was positive in all pheochromocytoma patients and negative in 15 control patients with 100% accuracy. The median values in the 2 groups were 59.3 ng/L and 33.7 ng/L (Z=-2. 440, P<0.05) for MN, 652.0 ng/L and 36. 3 ng/L (Z=-6.699, P<0.001) for NM, with 96. 7% (29/30) sensitivity, 86. 3% (44/51)specificity and 90.1% (73/81) accuracy for their combination ( either or both positive). There was no significantly statistical difference when compared with 13I-MIBG whole body scan findings (100. 0% ,P >0. 05). Conclusion The results show that the EIA method may be eligible as an alternative to HPLC for plasma metanephrines determination in the identification of pheochromocytoma.
