Diabetic kidney disease (DKD) is one of the common microvascular complications of diabetes mellitus (DM) and a primary cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD). Inflammation is currently a hot topic in exploring the pathogenesis of DKD. Macrophages, T cells, interleukins, tumor necrosis factor, NOD-like receptor protein 3 (NLRP3) inflammasome, Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway, and nuclear factor-kappa B (NF-κB)-related signaling pathway all play a role in regulating the inflammation of DKD and accelerating its progression. Astragali Radix, a Chinese herbal medicine, is widely used in the treatment of DKD and possesses strong anti-inflammatory effects. Studies have revealed that active ingredients of Astragali Radix, including polysaccharides, astragaloside Ⅳ, total flavonoids, calycosin, and quercetin, can regulate multiple signaling pathways to ameliorate the microinflammatory state and alleviate kidney damage, thereby slowing down the progression of DKD. This article systematically reviews the factors influencing the inflammation in DKD and analyzes recent research findings and mechanisms concerning active ingredients of Astragali Radix in the management of DKD inflammation, aiming to offer novel insights and directions for the prevention, treatment, and research of DKD.

Objective To study the seasonal distribution characteristics of polycyclic aromatic hydrocarbons (PAHs) in PM2.5 in Lianyungang City, and analyze the sources of PAHs pollution, and to evaluate the health risks of PAHs in different seasons. Methods PM2.5 samples were collected regularly from January 2019 to December 2023, and 16 types of PAHs were determined by HPLC. Kruskal-Wallis H test was used to compare the concentrations of PM2.5 and PAHs in different years and seasons. The source of PAHs was analyzed by characteristic ratio and principal component analysis (PCA). Health risks were assessed using the BaP equivalent method and the incremental lifetime cancer risk (ILCR) model. Results The annual exceedance rates of PM2.5 and BaP in Lianyungang showed a decreasing trend from 2019 to 2023. PM2.5, total PAHs and PAHs monomers (except Ace, Flu and Acy) all showed significant seasonal differences, with the highest concentration in winter (P<0.001). The average proportion of 4-ring PAHs was the highest and the average proportion of 2-ring PAHs was the lowest. The proportion of 5-6 ring PAHs was relatively high in winter and spring. PM2.5and PAHs were negatively correlated with temperature, relative humidity and precipitation, and were positively correlated with atmospheric pressure. PM2.5 was negatively correlated with wind speed, while some PAHs monomers were positively correlated with wind speed. The characteristic ratio and PCA results showed that the main sources of PAHs in Lianyungang City were mixed sources of road dust and vehicle emissions, oil pollution sources and biomass combustion sources. The results of ILCR showed that the highest risk was found in adults, with males slightly higher than females. In Lianyungang, the maximum value of ILCR in winter was more than 10-6 in people over 9 years old. Conclusion The main sources of PAHs in PM2.5 in Lianyungang City are mixed sources of road dust and vehicle emissions, oil pollution sources, and biomass combustion sources. Under the current exposure level of PAHs in PM2.5, residents have a certain potential carcinogenic risk.

OBJECTIVE To evaluate the quality of Mongolian medicine Sendeng-4 based on qualitative and quantitative analysis combined with chemical pattern recognition, in order to provide the reference for its quality control. METHODS The chemical components in Sendeng-4 were analyzed qualitatively by HPLC-Q-Exactive-MS. The contents of 16 components (methyl gallate, ethyl gallate, epicatechin, dihydromyricetin, genipin-1-O-β-D-gentiobioside, caffeic acid, catechin, corilagin, deacetylasperulosidic acid methyl ester, rutin, geniposide, luteolin, myricetin, quercetin, ferulic acid, and toosendanin) in 15 batches of Sendeng-4 (sample S1-S15) were quantitatively analyzed by HPLC-MS/MS. Cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares discriminant analysis were conducted and variable importance projection (VIP) value greater than 1 was used as the index to screen the differential components. RESULTS A total of 73 chemical components were identified in Sendeng-4, including 20 flavonoids, 16 tannins, 14 organic acids, etc. According to the quantitative analysis, the results exhibited that the average contentsthe of above 16 components in 15 batches of Sendeng-4 were 3.683-7.730, 2.391-6.952, 2 275.538-4 377.491, 2 699.188-3 537.924, 858.266-1 377.393, 3.366-11.003, 140.624-315.683,414.629-978.334, 285.501-1 510.457, 27.799-48.325, 3 625.415-6 309.563, 0.506-0.656, 442.337-649.283, 47.093-59.736, 12.942-15.822, 127.738-326.649 μg/g, respectively. According to the results of CA and PCA, 15 batches of samples could be clustered into two categories: S1-S3, S5-S6, S9-S10 and S13 were clustered into one category; S4, S7-S8, S11-S12, S14-S15 were clustered into one category. VIP values of geniposide, epicatechin, deacetylasperulosidic acid methyl ester and genipin-1-O- β-D-gentiobioside were all greater than 1. CONCLUSIONS HPLC-Q-Exactive-MS and HPLC-MS/MS techniques are employed for the qualitative and quantitative analysis of Sendeng-4. Through chemical pattern recognition analysis, four differential components are identified: geniposide, epicatechin, deacetylasperulosidic acid methyl ester, and genipin-1-O-β-D-gentiobioside.

Retinal displacement refers to the strong fluorescent lines parallel to the retinal vessels that are detected through autofluorescence examination after rhegmatogenous retinal detachment(RRD)surgery. Actually, even if patients with RRD achieve macroscopic structural reattachment after the operation, the visual function of some patients remains suboptimal. This is associated with the incomplete recovery of retinal function, and retinal displacement is one of the critical influencing factors. This paper reviews the related concepts of retinal displacement and systematically summarizes the incidence of retinal displacement after RRD surgery and its impact on function, the possible mechanisms of retinal displacement, and the influence of various factors on the occurrence of retinal displacement reported in the recent 5 a. It is conducive to enabling surgeons to conduct better design and planning for retinal reattachment surgeries, then achieve higher integrity of retinal function recovery, and enable patients to obtain better postoperative visual function.

ObjectiveTo investigate the ameliorative effect of paeonol on acute alcohol-induced hepatic inflammation in mice via the regulation of the short-chain fatty acids (SCFAs)-specific receptor GPR43/mitogen-activated protein kinase (MAPK) signaling pathway. MethodsC57BL/6 mice were randomly divided into five groups: blank control group, model group, low-dose paeonol group (120 mg·kg-1), high-dose paeonol group (480 mg·kg-1), and silybin group (36.8 mg·kg-1). A mouse model of alcohol-induced liver disease (ALD) was established by ad libitum administration of a Lieber-DeCarli alcohol liquid diet. Serum lipid levels, liver function, inflammatory cytokines, and oxidative stress markers were measured. Liver hematoxylin-eosin (HE) staining and Oil Red O staining were performed to validate successful modeling. Western blot analysis was used to assess the expression levels of zonula occludens-1 (ZO-1), Claudin-1, and proteins related to the GPR43/MAPK signaling pathway in the colonic tissue. Immunohistochemistry was employed to detect the protein expression of GPR43, ZO-1, and Claudin-1 in the colon. Then 16S rDNA sequencing was performed to analyze differences in intestinal flora between the model group and the high-dose paeonol group. Additionally, fecal microbiota transplantation (FMT) experiments were conducted to validate the regulatory effect of paeonol on ALD via modulation of intestinal flora. ResultsCompared with the blank control group, the model group showed significantly elevated serum lipid levels, oxidative stress, and inflammatory cytokine expression (P<0.01). Liver histology revealed increased inflammatory infiltration and lipid droplet accumulation. Colonic mucosal injury and impaired intestinal barrier function were observed. Levels of MAPK pathway-related proteins in the colonic tissue were upregulated (P<0.01), while GPR43, ZO-1, and Claudin-1 protein expression levels were significantly decreased (P<0.01). The composition and abundance of the intestinal flora were markedly altered, with a reduced Bacteroidetes-to-Firmicutes ratio and decreased relative abundances of Eubacterium, Parabacteroides, Erysipelothrix, and Adlercreutzia, alongside increased abundances of Clostridium butyricum, Enterococcus, and Helicobacter pylori in the model group. Compared with the model group, paeonol significantly reduced serum lipid levels, oxidative stress responses, and the expression of inflammatory cytokines in ALD mice (P<0.05, P<0.01). It also attenuated hepatic lipid accumulation, restored intestinal barrier function, and repaired the structural integrity of liver and colonic tissues. The protein expression levels of ZO-1, Claudin-1, and GPR43 in the colonic tissue were significantly increased (P<0.05, P<0.01), while those of MAPK pathway-related proteins were significantly decreased (P<0.05, P<0.01). The intestinal flora dysbiosis was effectively alleviated, rendering its composition closer to that of normal mice. The efficacy of paeonol in modulating ALD was further confirmed by FMT experiments, supporting its mechanistic involvement in the SCFAs-GPR43/MAPK signaling pathway. ConclusionPaeonol exerts a protective effect against ALD in mice, which may be mediated through regulation of the SCFAs-GPR43/MAPK signaling pathway, thereby achieving anti-inflammatory effects and improving intestinal barrier function.

This paper aims to discuss the construction and promotion strategy of medical care capacity framework based on the core literacy of palliative care, combining domestic and foreign research and clinical status. The research results show that it is particularly important to construct a framework of medical care competence based on palliative care. The core competencies required for palliative care include the ability to comprehensively evaluate and formulate personalized programs, effective communication skills, interdisciplinary teamwork skills, and the ability to continuously learn and improve themselves. The quality of care can be further improved if the above abilities are incorporated into the framework of medical care ability based on palliative care. However, there are a series of problems in the process of constructing the framework of palliative medical care capacity, such as difficult implementation of policy support, poor professionalism of talent team, single and irregular service model, low social acceptance, and difficult interdisciplinary cooperation and resource integration. After a detailed analysis of the problems, this paper puts forward the countermeasures to construct the framework of caring ability literacy based on palliative care. Effective countermeasures such as increasing policy support, cultivating comprehensive talents, developing diversified palliative care models, improving social recognition, and strengthening interdisciplinary cooperation and resource integration can effectively improve the core literacy and professional ability of medical care personnel, and then promote the development and improvement of palliative care services. In-depth discussion of the above contents can provide scientific reference for building a care model and literacy framework with palliative care as the core.

OBJECTIVE To investigate the ameliorative effects and mechanism of Sanwei ganlu on hepatic fibrosis in rats. METHODS The rats were randomly divided into normal group, model group, silibinin group (positive control, 50 mg/kg), and Sanwei ganlu low-dose, medium-dose, and high-dose groups (80, 250, 800 mg/kg). Except for normal group, hepatic fibrosis rat models were established by intraperitoneal injection of CCl4 in the other groups of rats. Starting from the 6th week of modeling administration, they were given normal saline or corresponding drugs intragastrically at the same time. At the end of the ninth-week experiment, liver and spleen indexes of rats were calculated; the pathological structure and fibrosis changes of liver tissue were observed by HE, Masson and Sirus Red staining. The contents of alanine transaminase (ALT), aspartate transaminase (AST), procollagen type Ⅲ (PC Ⅲ), collagen type Ⅳ (COL-Ⅳ), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and IL-1β in serum, and hyaluronic acid (HA) and laminin (LN) in liver tissue were all detected. RESULTS Compared with the model group, the liver injury and collagen fiber deposition of rats were improved to different extents in Sanwei ganlu groups and silibinin group; the contents of ALT, AST, PC Ⅲ, COL-Ⅳ, IL-6, TNF-α and IL-1β in serum as well as the contents of HA and LN in liver tissue significantly decreased (P<0.05 or P<0.01). CONCLUSIONS Sanwei ganlu can alleviate the progression of hepatic fibrosis in rats, possibly by inhibiting the synthesis of collagen fiber, reducing transaminase content, down-regulating the levels of HA, LN, PC Ⅲ and COL-Ⅳ, and reducing the inflammatory response.
