The excessive concentration of NO_(2) in the atmosphere has gained considerable attention due to its damage to the environment and human health. Gas sensor technology has important application prospects in detecting atmospheric NO_(2) concentration. Restricted by its wide bandgap, pristine ZnO needs additional energy to power the electronic transition as a gas sensing material.

Barium ferrite micro-/nanofibers with special morphology,nanowires with diameters of 100 nm,nanoribbons with diameters of 1μm,and nanotubes with outer diameter of about 300 nm while inner diameter of 100 nm were successfully prepared via electrospinning using different solvents（dimethyl formamide（DMF）,solutions of deionized water and ethyl alcohol,and solutions of deionized water and acetic acid,respectively）.The barium ferrite micro-/nanofibers were characterized by scanning electron microscope（SEM）,X-ray diffraction analysis（XRD）,and vibration sample magnetometer（VSM）.The results demonstrate that the pure BaFe12O19 ferrite phase is successfully *** the SEM results show excellent *** magnetic hysteresis loops demonstrate that their magnetic properties are quite different with different *** specific saturation magnetization is approximately the same（46.12-49.17 A·m^2·kg^-1）,but the coercivity of the BaFe12O19 increases from wires（190.08 kA·m^-1）,ribbons（224.16 kA·m^-1） to tubes（258.88 kA·m^-1）.

AIM： To investigate the effect of Tangweian Jianji （TWAJJ） on the biomechanical and morphometrical remodeling of the upper gastrointestinal tract in diabetic rats. METHODS： Diabetes was induced in 27 rats by in- jecting streptozotocin （40 mg/kg body weight）, the animals were then divided into three groups （n = 9 in each group）, i.e., diabetic control （DM）; high dose （10 g/kg, T1） and low dose （5 g/kg, T2）. Another 10 rats acted as normal controls （Control）. TWAJJ was admin- istered by gavage once daily. Blood glucose and serum insulin levels were measured. Circumferential length, wall thickness and opening angle were measured from esophageal, duodenal, jejunal and ileal ring segments. The residual strain was calculated from the morpho- metric data. Step-wise distension was carried out on esophageal and jejunal segments. The obtained data on the length, diameter and pressure changes were then used to calculate the circumferential and longitu- dinal stresses and strains. Real-time reverse transcrip- tion polymerase chain reaction was used to detect the receptor of advanced glycation end-products （RAGE） mRNA level in jejunal tissues. RESULTS： At the end of the experiment, the blood glucose level was significantly higher and the serum insulin level was significantly lower in DM, T1 and T2 groups than in the control group （Glucose： 30.23 ± 0.41 mmol/L, 27.48 ± 0.27 mmol/L and 27.84 ± 0.29 mmol/ L vs 5.05 ± 0.04 mmol/L, P = 1.65 x 10-16, P = 5.89 x 1019 and P = 1.63 x 10-Is, respectively; Insulin： 1.47 ± 0.32 °tg/L, 2.66 ± 0.44 pg/L, 2.03 ± 0.29 pg/L and 4.17 ± 0.54 pg/L, P = 0.0001, P = 0.029 and P = 0.025, re- spectively）. However, these levels did not differ among the DM, T1 and T2 groups. The wet weight per unit length, wall thickness and opening angle of esophageal and intestinal segments in the DM group were signifi- cantly higher than those in the control group （from P = 0.009 to P = 0.004）. These parameters in the T1 group were significantly lower than those in th
