    Abstract Background: Patients with foreign bodies in the digestive tract are often encountered, but complete penetration of a foreign body through the gastrointestinal tract is rare, and the choice of imaging method is very important. Improper selection may lead to missed diagnosis or misdiagnosis.
    Case summary: An 81-year-old man was diagnosed as having a liver malignancy after he took magnetic resonance imaging and positron emission tomography/computed tomography (CT) examinations. The pain improved after the patient accepted gamma knife treatment. However, he was admitted to our hospital 2 mo later due to fever and abdominal pain. This time, he received a contrast-enhanced CT scan, which showed fish-boon-like foreign bodies in the liver with peripheral abscess formation, then he went to the superior hospital for surgery. It lasted for more than 2 mo from the onset of the disease to the surgical treatment. A 43-year-old woman with a 1 mo history of a perianal mass with no obvious pain or discomfort was diagnosed as having an anal fistula with the formation of a local small abscess cavity. Clinical perianal abscess surgery was performed, and fish bone foreign body was found in perianal soft tissue during the operation.
    Conclusion: For patients with pain symptoms, the possibility of foreign body perforation should be considered. Magnetic resonance imaging is not comprehensive and that a plain computed tomography scan of the pain area is necessary.

    Abstract Coal chemical industry (CCI) generally utilizes reverse osmosis (RO) for water reclamation, which generates a highly concentrated stream containing refractory organic substances and high-concentration total dissolved solids (TDS). To address this issue, the present work focuses on volume reduction of RO concentrate (ROC) produced from CCI by forward osmosis (FO). We investigated the effects of membrane orientation and draw solution (DS) concentration on FO performance. Foulant removal was tested by using chemical cleaning, physical cleaning and osmotic backwash (OB). AL-FS (active layer facing feed solution) mode outcompeted AL-DS (active layer facing draw solution) mode, achieving a flux of 26.4 LMH, 92.5% water reclamation and energy consumption of 0.050 kWh·m

    Abstract Reverse osmosis (RO) is frequently used forwaterreclamation fromtreated wastewaterordesalination plants. The RO concentrate (ROC) produced from the coal chemical industry (CCI) generally contains refractory organic pollutants and extremely high-concentration inorganic salts with a dissolved solids content of more than 20 g/L contributed by inorganic ions, such as Na⁺,Ca²⁺,Mg²⁺,Cl⁻, and SO₄²⁻. To address this issue, in this study, we focused on coupling forward osmosis (FO) with chemical softening (FO-CS) for the volume minimization of CCI ROC and the recovery of valuable resources in the form of CaCO₃. In the case of the real raw CCI ROC, softenin₂g trea₂tment by lime-soda ash was shown to effectively remove Ca²⁺/Ba²⁺ (>98.5%) and Mg²⁺/Sr²⁺/Si (>80%), as well as significantly mitigate membrane scaling during FO. The softened ROC and raw ROC corresponded to a maximum water recovery of 86% and 54%, respectively. During cyclic FO tests (4 × 10 h), a 27% decline in the water flux was observed for raw ROC, whereas only 4% was observed for softened ROC. The cleaning efficiency using EDTA was also found to be considerably higher for softened ROC (88.5%) than that for raw ROC (49.0%). In additio₃ CaCO₃ (92.2% purity) was recovered from the softening sludge with an average yield of 5.6 kg/m³ treated ROC. This study provides a proof-of-concept demonstration of the FO-CS coupling process for ROC volume minimization and valuable resources recovery, which makes the treatment of CCI ROC more efficient and more economical.

    Abstract The dynamic mechanical behavior and cushioning performance of honeycomb sandwich panels, which are extensively employed in product cushioning packaging due to their exceptional energy absorption capabilities, were examined using a combination of experimental and numerical methods. Several factors, such as maximum acceleration-static stress, cushioning coefficient-static stress, and other curves, were analyzed under various impact conditions. The simulated stress-strain, deformation modes, cushioning coefficients, and other parameters demonstrate consistency with the experimental results. The acceleration, maximum compression, and cushioning coefficient obtained from the experiment and simulation calculation were 30.68 g, 15.44 mm, and 2.65, and 31.96 g, 14.91 mm, and 2.79, respectively. The results indicate that all error values were less than 5%, confirming the precision and reliability of the model. Furthermore, the model was utilized to simulate and predict the cushioning performance of honeycomb sandwich panels with different cell structures and paper thicknesses. These results provide a solid basis for enhancing the design of subsequent honeycomb element structures.

    Abstract To demonstrate the treatment effect on structural damage in rheumatoid arthritis (RA) and psoriatic arthritis (PsA), radiographic images of hands and feet are scored according to Sharp scoring systems in randomized clinical trials. However, the quantification of such an effect is challenging because the overall mean progression is lack of clinical interpretation. This article attempts to shed a light on the statistical challenges resulted from its scoring methods and heterogeneity of the study population and proposes a mixture distribution model approach to fit radiographic progression data. With such a model, the drug effect is fully captured by the mean progression of those patients who would progress in the study period under the control treatment. The resulting regression model also lends a tool in examining prognostic factors for radiographic progression. Simulations have been carried out to evaluate the precision of the parameter estimation procedure. Using the data examples from RA and PsA, we will show that the mixture distribution approach provides a better goodness of fit and leads to a casual inference of the study drug, hence a clinically meaningful interpretation.

    Abstract Huangqi-Danshen decoction (HDD), a Chinese herbal preparation, is effective in clinical treatment of chronic kidney disease (CKD). However, the underlying mechanism remains to be clarified. In this study, we aimed to investigate the role of HDD in the regulation of renal glucose metabolism in a CKD mouse model. The 0.2% adenine-induced CKD mouse model was administered HDD extract at a dose of 6.8 g/kg/day for 4 weeks. Detection of renal glucose metabolites was performed by ultra-performance liquid chromatography-tandem mass spectrometry. The expression of renal fibrosis and glucose metabolism-related proteins was tested by Western blotting, immunohistochemistry, and immunofluorescence. The results showed that HDD treatment could significantly reduce serum creatinine (0.36 ± 0.10 mg/dL vs. 0.51 ± 0.07 mg/dL, P < 0.05) and blood urea nitrogen (40.02 ± 3.73 mg/dL vs. 62.91 ± 10 mg/dL, P < 0.001) levels, and improve renal pathological injury and fibrosis. Aberrant glucose metabolism was found in the kidneys of CKD mice, manifested by enhanced glycolysis and pentose phosphate pathway, and tricarboxylic acid cycle inhibition, which could be partially restored by HDD treatment. Furthermore, HDD regulated the expression of hexokinase 2, phosphofructokinase, pyruvate kinase M2, pyruvate dehydrogenase E1, oxoglutarate dehydrogenase, and glucose-6-phosphate dehydrogenase in CKD mice. In conclusion, HDD protected against adenine-induced CKD, reshaped glucose metabolism profiles, and restored the expression of key enzymes of glucose metabolism in the kidneys of CKD mice. This study sheds light on targeting glucose metabolism for the treatment of CKD and screening small molecule compounds from herbal medicine to slow CKD progression.

    Abstract Objective To analyze the correlation between juvenile idiopathic scoliosis (JIS) patients with lumbar and thoracic scoliosis and the degree of pelvis obliquity in standing position and during walking. Methods The patients with JIS(Cobb≥10°) admitted into Peking Union Medical College Hospital from September 2020 to December 2022 and non-JIS patients(Cobb < 10°) during the same period were retrospectively included. According to the results of anteroposterior X-ray of the whole spine in the standing position, JIS patients were divided into a group with lumbar/thoracolumbar scoliosis (group A) and a group without lumbar/thoracolumbar scoliosis (group B). The change value of the bilateral iliac crest height, used as osseous landmarks, was measured in standing position and during walking. Bilateral iliac crest heights and their change values were measured in standing position and during the walking cycle to analyze the degree of pelvic coronal tilt in patients with different types of JIS. Results A total of 73 JIS patients (54 patients in group A, and 19 patients in group B) and 34 non-JIS patients who met the inclusion and exclusion criteria were enrolled. In group A, 61.1%(33/54) of patients showed a 'reasonable' relationship between the higher side of the iliac ridge and the convex side of the spine (the iliac ridge of the convex side of the lumbar spine/thoracolumbar spine was lower than that of the concave side), and 38.2%(13/34) of non-JIS patients showed a 'reasonable' relationship between the higher side of the iliac ridge and the convex side of the spine (the iliac ridge of the convex side of the lumbar spine/thoracolumbar spine was at the same height as that of the concave side). The difference was statistically significant(P=0.036). The proportion of 'reasonable' relationship in group B was not significantly different from that in non-JIS patients(26.3% vs. 38.2%, P=0.380). In group A, there were statistically significant differences in iliac crest height changes on both sides during the whole gait cycle ...
