Objective To determine if aquaporin1 ( AQP1) and aquaporin5 ( AQP5) are expressed in the alveolar-capillary membrane in rats, and to investigate the changes of AQP1 and AQP5 expression in the rat with acute lung injury.Methods The distribution of AQP1 and AQP5 in alveolar capillary membrane was investigated by immunohistochemistry and immunoelectron microscopy with affinity-purified antibodies to human AQP1 and AQP5.The possibility that alveolar capillary membrane AQP1 and AQP5 undergo altered regulation was studied by a rat model established using intra-tracheal instillation of lipopolysaccharide (LPS).Results Immunolabelling showed that AQP1 was stained primarily in the microvascular endothelium of normal lungs, while AQP5 was expressed in type I pneumocytes. Immunohistochemical analysis showed a significant decrease in the expression of AQP1 and AQP5 in injured lungs at 4 -48 h after LPS instillation.AQP1 protein was resumed partly at 24 h after LPS instillation and steroid administration, whereas AQP5 was unchanged.Conclusions The decreased expressions of AQP1 and AQP5 in injured lungs suggest that both of them may play a role in abnormal fluid transportation.

BACKGROUND:Open reduction is general y not advocated for the treatment of children clavicle fracture, because the thick and tough periosteum remains intact and attached by the ligament attachment. In clinic, twin-ring external fixation and simple suspension are commonly used, but there is no reliable basis on which method can get better effect.
OBJECTIVE:To compare the stability of twin-ring external fixation and simple suspension for the treatment of children clavicle fracture.
METHODS:The patients with children clavicle fracture and treated by twin-ring external fixation and simple suspension were selected from June 2008 to December 2012, including 17 patients treated with simple suspension and 22 patients treated with twin-ring external fixation. The X-ray film examination was performed regularly to observe the fracture healing and shoulder function.
RESULTS AND CONCLUSION:The 17 patients treated with simple suspension had good healing;three cases had gap between fracture ends at 1 week after treatment, and re-suspension to increase the height and final y two fracture ends contacted in one case;for the other two cases, there was stil gap between fracture ends, and changed for twin-ring external fixation, the fracture ends contacted. Al the 22 patients in the twin-ring external fixation group obtained healing;five cases had performance of upper extremity neurovascular compression on the fracture side after fixation;after releasing, three cases had recovery, and two cases were treated with simple suspension, the fracture ends began to contact;six cases had armpit redness;four cases had early sleep difficulties;two cases had gap between fracture ends at 1 week after treatment, and after re-adjust, the fracture ends contacted in two cases. The results showed both two methods could not cause appearance deformity, and both could get healing. The simple suspension fixation is easy to operate with reliable effect, and it is comfortable which make it easy to accept by the children, it has the advantages of early for functional exercise, less tissue damage, does not affect the blood supply;the twin-ring external fixation is easy to compress the axil ary arteries and nerves on both sides, thus resulting in upper extremity swel ing, numbness and skin redness, and it can cause discomfort night sleeping and poor comfort which is not easy for children to accept. But, no matter what method we take, the review after 1 week, as wel as the line between proximal and distal part and the contact between fracture ends is stil important.

Long non-coding RNA ( LncRNA) is a class of transcript (>200 nucleotides) that do not encode proteins. It plays an important role in epigenetic regulation and gene expression at transcriptional or post transcriptional level. The abnormal expression of LncRNA may lead to various pathological processes. Diabetic retinopathy ( DR ) is a multifactorial disease. Recent studies have shown that many specific expressions of LncRNAs are closely related to the genesis of DR. In this review, we summarized the recent advances in the function of LncRNA, the regulatory mechanisms of LncRNA involved in the development of DR, and the related therapies.

Diabetic macular edema ( DME ) is a major cause of visual impairment in patients with diabetes mellitus, the central retinal thickness ( CRT ) is correlated with the visual impairment and the changes of visual function before and after treatment. Furthermore, CRT is related to the changes of macular microstructure. The subtle changes of retinal microstructure can be qualitative and quantitative analyzed by spectral- domain OCT ( SD -OCT) . In this study, the changes of retinal microstructure in patients with DME are reviewed, what is of great meaning to explore mechanism, observe disease progress, guide clinical treatment and prospect prognosis of DME.

Objective To investigate the changes of tumor necrosis factor- ?(TNF- ?) and souble intercellular adhesion molecule - 1 (sICAM - 1) in serum and cerebrospinal fluid (CSF) in children with viral encephalitis (VE) before and after treatment,and to explore the pathogenesis of the cytokins in VE. Methods The levels of TNF - ? and sICAM - 1 in serum and CSF were determined before and after treatment using EL1SA in 38 children who were admitted with VE, and 20 children as normal controls. Results The levels of TNF- ? and sICAM - 1 in serum and CSF before treatment were obviously higher than those of control group,and the difference was significant(P 0. 05), but the serum and CSF TNF - ? and sICAM - 1 levels in SVE group were higher than those of control group(P
