AIM:To determine the relationship of pulmonary abnormalities and bowel disease activity in inflammatory bowel disease(IBD).METHODS:Thirty ulcerative colitis(UC)and nine Crohn's disease patients,and 20 control subjects were enrolled in this prospective *** clinical information was *** and activity of the bowel disease were established *** patient underwent pulmonary function tests and high-resolution computed tomography(HRCT).Blood samples for measurement of C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),angiotensin converting enzyme and total IgE were delivered by the ***:Ten(25.6%)patients had respiratory symptoms.A pulmonary function abnormality was present in 22 of 39 *** all patients,the most prevalent abnormalities in lung functions were a decrease in forced expiratory volume in 1 s(FEV1),FEV1/forced vital capacity(FVC),forced expiratory flow(FEF)25%-75%,transfer coefficient for carbon monoxide(DLCO),DLCO/alveolar *** respiratory symptoms score was associated with high endoscopic activity index in UC *** and clinical activities in UC patients were correlated with FEV1,FEV1/FVC,and FEF 25%-75%.Smoking status,duration of disease and medication were not correlated with pulmonary physiological test results,HRCT abnormalities,clinical/endoscopic disease activity,CRP,ESR or total IgE level or body mass ***:It is important that respiratory manifestations are recognized and treated early in ***,they can lead to destructive and irreversible changes in the airway wall.

With the increasing development of intelligent robots and wearable electronics,the demand for high-performance flexible energy storage devices is drastically *** this study,flexible symmetric microsupercapacitors(MSCs)that could operate in a wide working voltage window were developed by combining laser-direct-writing graphene(LG)electrodes with a phosphoric acid-nonionic surfactant liquid crystal(PA-NI LC)gel *** increase the flexibility and enhance the conformal ability of the MSC devices to anisotropic surfaces,after the interdigitated LG formed on the polyimide(PI)film surface,the devices were further transferred onto a flexible,stretchable and transparent polydimethylsiloxane(PDMS)substrate;this substrate displayed favorable flexibility and mechanical characteristics in the bending ***,the electrochemical performances of the symmetric MSCs with various electrode widths(300,400,500 and 600μm)were *** findings revealed that symmetric MSC devices could operate in a large voltage range(0–1.5 V);additionally,the device with a 300μm electrode width(MSC-300)exhibited the largest areal capacitance of 2.3 mF cm^(−2)at 0.07 mA cm^(−2)and an areal(volumetric)energy density of 0.72μWh cm−2(0.36 mWh cm^(−3))at 55.07μWcm−2(27.54mWcm−3),along with favorable mechanical and cycling *** charging for~20 s,two MSC-300 devices connected in series could supply energy to a calculator to operate for~130 s,showing its practical application potential as an energy storage ***,the device displayed favorable reversibility,stability and *** 12 months of aging in air at room temperature,its electrochemical performance was not altered,and after charging-discharging measurements for 5000 cycles at 0.07 mA cm^(−2),~93.6%of the areal capacitance was still retained;these results demonstrated its practical long-term application potential as an energy storage device.
