Epoxy resin/hollow glass beads-chopped basalt fiber (EP/HGM-CBF) composite foam materials with different fiber mass fractions of CBF were prepared. The effects of the solution corrosion environment on the compression properties of the specimens were investigated by immersing the composite foam material specimens in distilled water, seawater, and seawater with five times the concentration of the compounds, and the causes were analyzed by combining scanning electron microscope photographs and EDS energy spectrometry. The study shows that the moisture absorption rate of the specimen first increases and then decreases with the increase of fiber mass fraction, and the moisture absorption rate is the largest at 10% fiber mass fraction, and the moisture absorption rate is larger in distilled water than in seawater, and the increase of the particle concentration in the solution decreases the diffusion coefficient of the solution. In the solution-immersed corrosive environment, the compression properties of EP/HGM-CBF composite foams all increased with the increase of CBF mass fraction, and reached a maximum when the CBF mass fraction was 30%, and the greatest increase in compression strength and compression modulus was seawater with five times the concentration of the compounds, and the compression strength was increased by 28.4% compared with that of the specimens without CBF. The solution corrosive environment decreased the compressive mechanical properties of the specimens, and the damage forms of the composites were different in the distilled water and seawater environments; the distilled water environment was mainly physical damage such as the dissolution of resin leading to interfacial debonding, whereas the seawater environment was mainly chemical damage due to the dissolution of the interfacial structure by elemental Cl.

Aim: To explore whether and to what extent, nurse–patient assessment differences mediate the association between nurse‐to‐patient ratios and readiness for hospital discharge, and examine whether nurse–patient characteristics moderate the indirect and/or direct effect of mediation model. Design: A cross‐sectional study was carried out from March 2021 to December 2022. Methods: A total of 523 pairs of gastrointestinal cancer patients with PICC and their nurses were recruited. All the participants were invited to complete the general information questionnaire and the Readiness for Hospital Discharge Scale. Outcome measure was patient‐reported readiness for hospital discharge. This study was reported according to the STROBE checklist. Results: The patients reported a low level of readiness for hospital discharge. Nurse–patient assessment differences were positively associated with nurse‐to‐patient ratios but negatively associated with readiness for hospital discharge. Furthermore, nurse–patient assessment differences fully mediated the effect of nurse‐to‐patient ratios on readiness for hospital discharge, and age and gender of patients only moderated the indirect path of mediation model.

Based on the software of traditional Chinese medicine inheritance support system (TCMISS), this article aims to analyze the experience and composition rules for cough from the descendant of Meng He Medical School, Xu Di-hua. The cough cases treated by Xu Di-hua were collected, and recorded into TCMISS (V2.0). Data mining methods such as Apriori algorithm and complex system entropy cluster were used to analyze the medication principles of Xu Di-hua for cough from pathogenesis and therapeutie aspects, and dig out the frequency of the herbs in prescription, core medicine and new combinations. The experience of curing cough from Professor Xu Di-hua were well found in the research. He is good at choosing prescriptions accurately, and pays attention to simultaneous use of cold and moisture drugs with combination of tonification and purgation. He is skilled in adding or reducing materia medica flexibly, as well as regulating lung to relieve cough and eliminating phlegm by clearing heat.

Gastric schwannomas are rare mesenchymal tumors of the gastrointestinal tract. They are usually misdiagnosed as other submucosal tumors preoperatively. Experience of the imaging features of gastric schwannomas is extremely limited. In this report, we summarize the features of a series of endoscopic ultrasound (EUS) images of gastric schwannomas in an effort to improve the diagnosis and differential diagnosis rate. We retrospectively reviewed the endosonographic features of four patients with gastric schwannomas and their computed tomography imaging results. Gastric schwannomas had heterogeneous hypoechogenicity or isoechogenicity, and a well-demarcated margin. The tumors originated from the fourth layer. Cystic changes and calcification were uncommon. Marginal hypoechoic haloes were observed in two patients. The results described here were different from those of previous studies. In the EUS evaluation, the internal echogenicity of gastric schwannomas was heterogeneous and low, but slightly higher than that of muscularis propria. These features might help us differentiate gastric schwannomas from other submucosal tumors. Further investigation is needed to differentiate these mesenchymal tumors.

Objective: To study the effect of emodin on pancreatic fibrosis and potential mechanism thereof., Methods: Fifty SD rats were randomly divided into 5 equal groups: normal control group, model control group, low-dose emodin-treated group, mediate-dose emodin-treated group, and high-dose emodin-treated group. The rats of the latter 4 groups underwent infusion of trinitrobenzene sulfonic acid (TNBS) into the pancreatic duct so as to establish models of pancreatic fibrosis. The emodin-treated rats were fed with different doses of emodin (20, 40, and 80 mg/kg body weight), while the normal and model control groups received 0.9% sodium chloride solution instead. Twenty-eight days later the rats were killed, blood samples were collected, and their pancreases were taken out. The serum levels of hyaluronic acid (HA) and laminin (LN) were determined by radioimmunoassay. The histopathological alterations were studied by optical microscopy. The expression of collagen was examined by Van Gieson staining. Western blotting was used to detect the protein expression of transforming growth factor-beta(1) (TGF-beta(1))., Results: (1) The serum level of HA of the low-dose, mediate-dose, and high-dose emodin-treated groups were 87 microg/L +/- 22 microg/L, 78 microg/L +/- 25 microg/L, and 62 microg/L +/- 19 microg/L respectively, all significantly lower than that of the model control group (113 microg/L +/- 27 microg/L, P < 0.05 or < 0.01). The serum levels of laminin in the low-dose, mediate-dose, and high-dose emodin-treated groups were 67 microg/L +/- 14 microg/L, 57 microg/L +/- 12 microg/L, and 44 microg/L +/- 10 microg/L respectively, all significantly lower than that of the model control group (86 microg/L +/- 17 microg/L, P < 0.05 or P < 0.01); (2) The degrees of fibrosis of the emodin-treated groups were obviously ameliorated in comparison with the model control group, the higher the dose of emodin the more improved the pathological changes, especially in the high-dose emodin-treated group (P < 0.05). (3) The percentages of collagen positive cells of the low-dose, mediate-dose, and high-dose emodin-treated groups were 39% +/- 7%, 38% +/- 4%, and 36% +/- 5% respectively, all lower than that of the model control group (42% +/- 6%), with a significant difference between the high-dose emodin-treated group and the model control group (P < 0.05). (4) The protein content of TGF-beta(1) of the low-dose, mediate-dose, and high-dose emodin-treated groups were 44.3% +/- 2.1%, 39.2% +/- 1.8%, and 28.8% +/- 1.6% respectively, all significantly lower than that of the model control group (60.7% +/- 1.7%, all P < 0.05), and the protein content of TGF-beta(1) of the high-dose emodin-treated group was significantly lower than those of the other 2 emodin-treated groups (both P < 0.05)., Conclusion: Emoidn has an anti-fibrosis effect on pancreatic fibrosis, which maybe related to the content of TGF-beta(1) protein.

The aim of this article was to investigate the mechanisms of emodin in antagonizing against organ fibrosis, and to illustrate that emodin can be an effective Chinese herbal preparation for treatment of organ fibrosis.
