To investigate their pathogenesis, we performed infrared spectroscopic analysis of meconium-calcified lesions. Methods: Meconium calculi were collected from the colostomy in a newborn patient with imperforate anus and rectourethral fistula. The potassium bromide method was employed to obtain the infrared absorption spectrum of the meconium calculi. Results: The wavelength pattern of the meconium calculi exhibited 4 specific peaks at 1570, 1390, 1105,and 1005 cm-1 between 22%and 45%transmittance values. The unique absorption spectrum exclusively indicated ammonium hydrogen urate (C5N5O3H7), having the combined constituents of ammonium and uric acid. Conclusions: These results suggest that the intraluminal meconium calculi were originally derived from meconium and fetal urine. The stasis of meconium passage and fetal urine mixing through the rectourethral fistula in a low-pH condition was deduced to be the main cause of this rare stone formation.展开更多

Specific energy absorption(SEA) was defined as the energy absorbed by the honeycomb structure per unit volume. This parameter was often used for determining the crashworthiness of thin-walled structures. In order to find the most optimized metal square honeycomb structure with the maximum SEA and the lowest peak stress, the cell length and the foil thickness of the metal honeycombs were optimized, with a low peak stress and a high SEA set as the two primary objectives. The pre-processing software Patran was used to build FE models, and the explicit solver LS-DYNA was employed to perform the crashworthiness analyses. The results show that the square honeycomb exhibits good energy absorption performance in some cases. The geometry is effective using 16.8% less buffer structure volume than the hexagonal honeycombs with a peak stress limitation of 1.21 MPa.展开更多

The patients were divided into three groups according to level of total bilirubin (< 100umol/L, 100 - 250umol/L, >250umol/L), the difference among three levels are significant. however, there are no difference of temperature. HB, pH, Pao2, PaCO2, AB and hemoglobin saturation measured by pulse oximetry among three groups. These results suggest that neonatal hyperbilirubinemia dose not interfere with pulse oximetry readings directly. Because bilirubin and carbon monoxide are produced during the hemolysis, thus increasing CoHB level, resulting in the overestimation of hemoglobin saturation by pulse oximetry. The co-oximeter is required to determine the concentrtion of CoHB and correct the CoHB-inducde spectral error.展开更多

The main challenge in the construction of flexible PDs is to maintain the optoelectronic performance during repetitive bending, folding and stretching.Herein, flexible PDs based on ZnO nanowires(NWs) and CsPbBr3 nanosheets(NSs) were constructed by an integrated low-dimensional structure strategy. Benefiting from the flexibility of unique sheet and wire structures, the PDs were able to maintain excellent operational stability under various mechanical stresses. For example, the PDs exhibited no obvious changes in optoelectronic performance after bending for 1000 times. Additionally, the PDs exhibited an integrated broadband response ranging from ultraviolet to visible region due to the combination of the intrinsic light absorption capability of ZnO and CsPbBr3. The PDs demonstrated high responsivities of 3.10 and 0.97 A W^-1 and detectivities of 5.57×10^12 and1.71×10^12 Jones under ultraviolet and visible light irradiation,respectively. The proposed construction strategy for highly flexible and performance-integrated PDs shows great potential in future smart, wearable optoelectronic devices.展开更多
