OBJECTIVE To study the improvement effect and mechanism of Tripterygium wilfordii multiglucoside （TWM） on nephrotic syndrome in rats. METHODS The nephrotic syndrome model was established by intravenous injection of adriamycin via the tail vein. The modeling rats were randomly divided into the model group （distilled water）， prednisone group （10 mg/kg）， and TWM high- and low-dose groups （10 and 5 mg/kg， respectively）. Additionally， blank group （distilled water） without model induction was established. Each group consisted of 9 rats. Rats in each group were administered the corresponding drugs or distilled water by gavage， once a day， for 6 consecutive weeks. The histopathological morphology of kidney tissues in rats was observed； the levels of 24-hour urinary protein （24 h-UTP） and serum biochemical indicators [albumin （ALB）， blood urea nitrogen （BUN）， serum creatinine （SCr）， cholesterol （CHOL）， and triglyceride （TG）] in rats were determined； the levels of oxidative stress indicators [superoxide dismutase （SOD）， malondialdehyde （MDA）] in kidney tissue of rats were determined； expressions of hypoxia-inducible factor-1α （HIF-1α）/microRNA-155-5p （miR-155-5p）/nuclear factor erythriod 2- related factor 2 （Nrf2） signaling pathway-related mRNA and protein in the renal tissues of rats were detected. RESULTS Compared with the blank group， the rats in the model group exhibited disordered renal tissue structure， with a small amount of glomerular necrosis and edema of the renal tubular epithelial cells. 24 h-UTP， serum levels of SCr， BUN， CHOL and TG， MDA content， mRNA and protein expressions of HIF-1α and Keap1 as well as the expression of miR-155-5p in renal tissues were increased significantly （ P ＜0.05）. Serum level of ALB， SOD level in renal tissue as well as mRNA and protein expressions of Nrf2 were decreased significantly （ P ＜0.05）. Compared with the model group， TWM high-dose and low-dose groups exhibited significant improvements in renal injury， with notable reversals in the levels of the above quantitative indicators （ P ＜0.05）. CONCLUSIONS TWM can alleviate oxidative stress-induced damage and thereby improve nephrotic syndrome in rats by regulating the HIF-1α/miR-155-5p/Nrf2 signaling pathway.

OBJECTIVE To investigate the improving effect of Yiqi yangyin huoxue formula on renal injury in immunoglobulin A nephropathy （IgAN） rats， and explore its potential molecular mechanism based on nuclear-enriched abundant transcript 1 （NEAT1）/receptor of activated C kinase 1 （RACK1）/NOD-like receptor family pyrin domain containing 3 （NLRP3） pathway.METHODS SD rats were divided into blank group and model-establishing group. Rats in the model-establishing group were induced to establish IgAN model by combined treatment of bovine serum albumin， carbon tetrachloride and lipopolysaccharide. Rats with successful model establishment were randomly divided into model group， prednisone acetate group （6.25 mg/kg）， low-dose and high-dose Yiqi yangyin huoxue formula groups （11， 22 g/kg）. Each group was intragastrically administered corresponding drugs or normal saline once a day for 6 consecutive weeks. After the last administration， urinary red blood cell count， 24-hour urinary total protein （24 h-UTP）， serum creatinine （Cr）， blood urea nitrogen （BUN）， albumin （ALB）， alanine amino-transferase （ALT） and interleukin-1β （IL-1β） levels were detected. Pathomorphological changes of renal tissues and immunoglobulin A （IgA） deposition in glomerular mesangial region were observed. The mRNA expression of NEAT1， as well as mRNA and protein expression levels of RACK1 and NLRP3 in renal tissues were determined.RESULTS Compared with the blank group， the model group presented glomerular mesangial matrix hyperplasia accompanied by inflammatory cell infiltration， and extensive renal tubular dilation with focal atrophy. The levels of 24 h-UTP， urinary red blood cell count， serum IL-1β， Cr， BUN， ALT， mean fluorescence intensity of IgA deposition in glomerular mesangial area， mRNA expression level of NEAT1， mRNA and protein expression levels of RACK1 and NLRP3 in renal tissues were significantly increased （ P ＜0.05）， while serum ALB level was significantly decreased （ P ＜0.05）. Compared with the model group， the glomerular structure was basically restored and renal tubular injury was obviously alleviated in low-dose and high-dose Yiqi yangyin huoxue formula groups； all the above quantitative indicators were significantly reversed （ P ＜0.05）.CONCLUSIONS Yiqi yangyin huoxue formula can mitigate the inflammatory response and ameliorate renal injury in IgAN rats， and its mechanism may be related to the inhibition of NEAT1/RACK1/NLRP3 pathway activity.

ObjectiveTo evaluate the quality of clinical practice guidelines and expert consensus statements on knee osteoarthritis （KOA） based on the Appraisal of Guidelines for Research & Evaluation Ⅱ （AGREE Ⅱ）， thus providing a new perspective for clinical selection as well as guideline development and updating. MethodsA systematic search was conducted for KOA-related guidelines and consensus statements published from November 1， 2019 to December 31， 2025. The databases and platforms searched included CNKI， VIP， Wanfang Data， PubMed， Web of Science， the National Institute for Health and Care Excellence （NICE）， SinoMed， Yimaitong， and relevant official websites. Two researchers independently screened the literature， and four researchers used AGREE Ⅱ to score the included documents and completed the quality appraisal after reaching a unified understanding. Subgroup analyses were further performed according to developing organization， document type， medical approach， funding status， and region of development， and longitudinal comparisons were conducted by year of publication. ResultsA total of 23 guidelines and consensus statements were included. The standardized scores of the six AGREE Ⅱ domains， from the highest to the lowest， were clarity of presentation ［（70.36±8.13）%］， scope and purpose ［（67.46 ± 11.44）%］， editorial independence ［（64.50±20.01）%］， rigor of development ［（62.24±15.26）%］， stakeholder involvement ［（55.73±10.29）%］， and applicability ［（53.89±13.17）%］. In terms of overall recommendation， 6 documents were rated as grade A and 17 as grade B. Stratified analyses showed that professional organizations scored higher than comprehensive organizations. The overall scores of traditional Chinese medicine/integrative medicine and Western medicine guidelines （or consensus statements） were similar. Guidelines scored higher than consensus statements. The overall scores were similar between documents with reported funding and those without reported funding. International guidelines scored higher than domestic guidelines. Longitudinal comparisons showed that the largest number of documents was published in 2021. The overall scores were higher in 2021—2022， and some domain scores declined in 2023—2024. Overall， the quality of recent guidelines and consensus statements for KOA showed slight fluctuations， without a clear linear trend. ConclusionThe included guidelines and consensus statements for KOA can generally serve as references for clinical practice. However， the quality across domains remains uneven， and stakeholder involvement and applicability are still weak domains. Future guideline development and updating should further improve methodological standardization and transparency in reporting.

AIM: To explore the clinical application effect of visual training equipment combined with conventional corrective treatment on children with ametropic amblyopia(AMA).METHODS: Prospective randomized control study. A total of 188 children(376 eyes)with AMA treated in our hospital from June 2021 to December 2022 were selected, and they were divided into two groups using a random number table. The conventional correction group(94 cases, 188 eyes)received conventional correction treatment, while the visual training group(94 cases, 188 eyes)received visual training equipment combined with conventional correction treatment, both lasted for 12 mo. The best corrected visual acuity, diopter, eye accommodation function, adverse reactions, amblyopia recurrence rates, and clinical efficacy were compared between the two groups at 6 and 12 mo after treatment.RESULTS:The two groups each had 8 cases(16 eyes)detached, the rate of loss to follow-up was 8.5%, and 86 cases(172 eyes)were included in each group. There were statistically significant differences in the best corrected visual acuity, diopter, amplitude of accommodation, accommodation facility and accommodative lag between the two groups of children before and after treatment(all P<0.05). The total effective rate of the visual training group(98.8%)was higher than that of the conventional correction group(91.9%; P<0.05). There was no statistically significant difference in the total effective rate of clinical efficacy between the two groups in different age groups and different degrees of amblyopia(all P>0.05). There was no statistically significant difference in the incidence of redness and swelling between the two groups(P>0.05). The recurrence rate of amblyopia in the visual training group(1.2%)was lower than that in the conventional correction group(8.1%; P<0.05).CONCLUSION: The combination of visual training equipment and conventional correction therapy has a significant clinical effect on children with AMA, which can effectively correct visual acuity, adjusting diopter and improve eye accommodation function, and recurrence rate of amblyopia is low and safety is high.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

Epidemiology research has found that ABO blood group and the gene coding ABO glycosyltransferases are associated with many human diseases. The activity of ABO glycosyltransferases varies with different blood types, mediating different glycosylation modifications. The variation in glycosylation level might be the risk factor of specific disease. Based on the literature retrieval and analysis, glycosylation levels regulated by ABO glycosyltransferases mainly affect the ABH blood group antigens and von Willebrand factor (vWF). By modulating key glycosylation components, ABO glycosyltransferases partly determine the activity or expression levels of the ABH antigens and vWF, thereby affecting the development and progression of diseases. Exploring the pathogenic mechanisms of ABO glycosyltransferases can improve the understanding of the molecular pathology of related diseases and provide reference for clinical research and application.

Objective:To preliminarily explore whether sirtuin1 (SIRT1) activation can inhibit neuronal ferroptosis in rats after traumatic brain injury (TBI) by regulating hypoxia-inducible factor-1α (HIF-1α)-mediated glycolysis.Methods:(1) Six SD rats were randomly divided into sham-operated group and TBI group, with 3 rats in each group; TBI model in the TBI group was established by hydraulic impact method, and rats in the sham-operated group underwent same surgery without impact. Cortical tissues of the two groups were sent for tandem mass tag (TMT) labeled quantitative proteomics detection to analyze the differential expression proteome; Kyoto encyclopedia of genes and genomes (KEGG) and gene set enrichment analysis (GSEA) were used to detect pathway enrichment of the screened differential proteins. (2) Twelve SD rats were randomly divided into sham-operated group and 1-day, 3-day and 7-day post-TBI groups, with 3 rats in each group. Treatment methods were the same as above; Western blotting was used to detect SIRT1 protein expression. (3) Forty-eight rats were randomly divided into sham-operated group, TBI group, TBI+vehicle group and TBI+SIRT1 agonist group, with 12 rats in each group; rats in the sham-operated group and TBI group accepted treatment as above; rats in the TBI+SIRT1 agonist group were intraperitoneally injected with SRT1720 (dissolved in ≤ 5% dimethyl sulfoxide, at a dose of 20 mg/kg) within 30 minutes after modeling, twice a day (with an interval of 12 hours); and rats in the TBI+vehicle group were injected with same dose of dimethyl sulfoxide at the same time. One d after modeling, neurological deficit was assessed using modified Neurological severity score (mNSS), brain water content was measured by dry-wet weight method, histopathological changes in the cortical lesions were observed by HE staining, mitochondrial ultrastructure was examined by transmission electron microscopy, malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in the brain tissues were detected by colorimetry, and protein expressions of SIRT1, HIF-1α (key protein in the glycolytic pathway), glutathione peroxidase 4 (GPX4, key protein in the ferroptosis pathway), and acyl-CoA synthetase long-chain family member 4 (ACSL4, key protein in the ferroptosis pathway) were evaluated by Western blotting.Results:(1) KEGG analysis revealed that the glycolysis pathway and HIF-1 signaling pathway were obviously enriched in the cortical tissues of rats in the TBI group compared with the sham-operated group; GSEA showed that the HIF-1 signaling pathway (mmu04066) and ferroptosis pathway (mmu04216) gene sets in the cortical tissues of rats in the TBI group exhibited enrichment trends compared with those in the sham-operated group. (2) Compared with the sham-operated group, the 1-day, 3-day, and 7-day post-TBI groups had significantly decreased SIRT1 protein expression ( P<0.05), with the most prominent decline in 1-day post-TBI group. (3) Compared with the TBI+vehicle group, rats in the TBI+SIRT1 agonist group showed significantly reduced mNSS score and brain tissue water content (9.83±1.17 vs. 7.66±1.21; [83.62±0.91]% vs. [80.09±0.68]%, P<0.05). HE staining indicated clearer structure of the cortical area at the injury sites, and improved neuron morphology in the TBI+SIRT1 agonist group compared with those in the TBI+vehicle group; and transmission electron microscopy showed reduced mitochondrial shrinkage and partial restoration of cristae structures in the TBI+SIRT1 agonist group compared with those in the TBI+vehicle group. Compared with the TBI+vehicle group, the TBI+SIRT1 agonist group exhibited significantly decreased MDA content ([62.72±9.20] nmol/g vs. [39.34±3.48] nmol/g), increased SOD activity ([1.95±0.23] U/mg vs. [2.48±0.14] U/mg), elevated GPX4 protein expression (0.37±0.04 vs. 0.46±0.03), and decreased HIF-1α and ACSL4 protein expressions (1.16±0.15 vs. 0.81±0.12; 1.14±0.06 vs. 1.29±0.04), with significant differences ( P<0.05). Conclusion:SIRT1 activation can exert neuroprotective effect by inhibiting HIF-1α-mediated glycolysis and reducing neuronal ferroptosis after TBI.

Soybean meal (SBM) prepared by soybean crushing is the most popular protein source in the poultry and livestock industries (Cai et al., 2015) due to its economic manufacture, high protein content, and good nutritional value. Despite these benefits, SBM contains various antigen proteins such as glycinin and β-conglycinin, which account for approximately 70% of the total proteins of the SBM and reduce digestibility and damage intestinal function (Peng et al., 2018). Treating SBM with proteases (neutrase, alcalase, and trypsin) or fermentation can eliminate these antigen proteins (Contesini et al., 2018). Because of its safety and rapid growth cycle, Bacillus strains are considered ideal for the fermentation industry (Yao et al., 2021). SBM fermented by Bacillus yields products with high nutritional value and low levels of antinutritional factors (ANFs), stimulating research in this area (Yuan et al., 2017). Kumari et al. (2023) demonstrated that fermentation with Bacillus species effectively degrades antigen proteins and increases crude protein content. The degradation of antigen proteins relies on protease hydrolysis. Low protease production is the major obstacle hindering the widespread use of microbial fermentation techniques.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.
