ObjectiveTo investigate the effect of quercetin on acute gouty arthritis (GA) in rats by inhibiting the reactive oxygen species (ROS)/NOD-like receptor protein 3 (NLRP3)/interleukin-1β (IL-1β) signaling pathway. MethodsSixty SPF-grade male SD rats were randomized into normal, model, colchicine (0.3 mg·kg-1), and low-, medium-, and high-dose (25, 50, 100 mg·kg-1, respectively) quercetin groups (n=10). The rats in the dosing groups were administrated with the corresponding drugs (10 mL·kg-1) by gavage once a day for one week. An equal volume of normal saline was given by gavage to rats in normal and model groups. One hour after drug administration on day 5, an acute GA model was established in other groups except the control group via intra-articular injection of monosodium urate (MSU) suspension into the right posterior ankle joint cavity. The joint swelling and gait were scored at the time points of 6, 12, 24, 48 h after modeling. Histopathological alterations in the ankle joint tissue from each group were assessed by hematoxylin-eosin (HE) staining. Malondialdehyde (MDA), xanthine oxidase (XOD), and total superoxide dismutase (T-SOD) assay kits were used to assess the levels of MDA, XOD, and T-SOD in the serum. The levels of tumor interleukin-6 (IL-6), necrosis factor-α (TNF-α), and IL-1β in the rat serum, as well as ROS in the ankle joint tissue, were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was performed to determine the protein levels of NLRP3, thioredoxin-interacting protein (TXNIP), apoptosis-associated speck-like protein containing a CARD domain (ASC), precursor cysteinyl aspartate-specific proteinase-1 (pro-Caspase-1), cleaved Caspase-1 (Caspase-1 p20), and IL-1β in the ankle joint tissue. Real-time PCR was employed to assess the mRNA levels of TXNIP, NLRP3, ASC, IL-1β, and TNF-α in the ankle joint tissue. ResultsCompared with the normal group, the model group exhibited decreased spontaneous activity, mental fatigue, increased ankle joint swelling and gait scores (P<0.01), aggravated synovial tissue edema and inflammatory cell infiltration (P<0.01), elevated levels of XOD, MDA, TNF-α, IL-1β, and IL-6 in the serum and ROS in the joint tissue (P<0.01), a declined level of T-SOD (P<0.01), up-regulated protein levels of NLRP3, TXNIP, ASC, pro-Caspase-1, Caspase-1 p20, and IL-1β in the ankle joint tissue (P<0.01), and up-regulated mRNA levels of NLRP3, TXNIP, ASC, IL-1β, and TNF-α in the ankle joint tissue (P<0.01). Compared with the model group, the medium- and high-dose quercetin groups showed improved general conditions, decreased gait scores (P<0.05, P<0.01), reduced joint swelling (P<0.01), alleviated synovial tissue edema and inflammatory cell infiltration (P<0.05, P<0.01), lowered levels of XOD, MDA, TNF-α, IL-1β, and IL-6 in the serum and ROS in the joint tissue (P<0.01), increased levels of T-SOD (P<0.01), down-regulated protein levels of TXNIP, NLRP3, ASC, pro-Caspase-1, Caspase-1 p20, and IL-1β in the ankle joint tissue (P<0.05, P<0.01), and down-regulated mRNA levels of TXNIP, NLRP3, ASC, IL-1β, and TNF-α in the ankle joint tissue (P<0.01). Low-dose quercetin also ameliorated some of the above parameters (P<0.05, P<0.01). ConclusionQuercetin exerts anti-GA effects by blocking the ROS/NLRP3/IL-1β signaling pathway, downregulating NLRP3 inflammasome activation, and inhibiting the production of pro-inflammatory cytokines including TNF-α, IL-1β, and IL-6.

ObjectiveHistorically documented Zhejiang Atractylodis Macrocephalae Rhizoma(Baizhu) possesses premium characteristics such as phoenix-like head and crane-like neck, pronounced sweetness, and fragrant aroma. However, its current market circulation is low, and the processed products with Zhejiang-style characteristics are at the risk of being lost. This study aims to preserve the ancient Zhejiang-style processing techniques and evaluate them using modern scientific methods. MethodsMultidimensional intelligent sensory evaluation was used to digitally characterize the "quality-structure" of the external appearance of nine-steamed and nine-processed Baizhu medicinal materials(intermediate processed products) and the "odor-taste" of the internal quality of its decoction pieces(slices), and the appearance parameters were digitally characterized by colorimeter, texture analyzer, electronic nose and electronic tongue, the chemical composition was analyzed via ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS). Then, cluster analysis on the differences in odor between the medicinal materials(intermediate processed products) and decoction pieces(slices) of nine-steamed and nine-processed Baizhu was conducted, as well as the differences in taste between water-soluble and alcohol-soluble extracts of the decoction pieces(slices), and the correlation analysis of chroma value-alcohol-soluble extract content-component response value. ResultsThe nine-steamed and nine-processed Baizhu had a dark brown to black epidermis, a brownish-yellow to brownish-gray cross-section, a slightly tough texture, a faint odor, and a slightly sweet, bitter and pungent taste. Texture analyzer measurements revealed minimal adhesion and maximum recovery in the middle section of the characteristic processed Baizhu, consistent with the processing endpoint of thorough steaming and cooking. The head section showed the highest internal hardness, elasticity and chewiness, indicating a denser texture in this area. The electronic nose sensor could clearly distinguish the difference between the medicinal materials and its decoction pieces, with a more significant clustering effect at 60 ℃ for 30 minutes compared to ambient temperature headspace for 2 hours, highlighting the significant impact of the baking degree before slicing on the quality. The electronic tongue taste signal map clearly distinguished the differences between water-soluble and alcohol-soluble extracts of nine-steamed and nine-processed Baizhu decoction pieces, and the addition of auxiliary materials during processing could enhance its alcohol-soluble extract content. A total of 82 chemical components were identified in the characteristic processed Baizhu. After processing, the contents of 58 components increased, while 24 components decreased. Correlation analysis revealed significant negative correlations(P<0.01) between ethanol-soluble extract content and colorimetric values of brightness(L*), yellow-bule value(b*), and total color difference(E*ab). E*ab showed marked negative correlations(P<0.05) with the response values of isochlorogenic acid A and C. ConclusionThis study establishes a modern intelligent sensory evaluation model for multidimensional holographic characterization of nine-steamed and nine-processed Baizhu, clarifying the correlation between increased isochlorogenic acid content and the visual color appearance after different steaming cycles, as well as its intrinsic alcohol-soluble extracts. This provides a reference for quality evaluation and processing standards of the Zhejiang-style characteristic processed products.

Gouty arthritis (GA) is caused by monosodium urate(MSU) deposition due to purine metabolism disorders. In traditional Chinese medicine (TCM), it falls under the category of "dampness-heat Bi syndrome", with core pathogenesis involving dampness-heat accumulation and dysfunction of the spleen and kidney. The dampness-heat syndrome is the most common and the primary syndrome type during acute attacks. In Western medicine, GA is associated with purine metabolism imbalance and inflammation triggered by MSU crystals, involving pathways such as NOD-like receptor protein 3 (NLRP3) inflammasome activation and Toll-like receptor 2/4 (TLR2/4) signaling. Clinically, colchicine and similar drugs are commonly used to treat GA, although long-term use carries potential side effects. Ermiao Formula analogs originate from ancient prescriptions, including Ermiao, Sanmiao, and Simiao compound formulas. All contain Atractylodis Rhizoma and Phellodendri Chinensis Cortex. Ermiaowan follow a 1∶1 formulation ratio. Sanmiaowan add Cyathulae Radix. Simiaowan further incorporate Coicis Semen. These formulas are rich in active ingredients, including alkaloids, terpenoids, flavonoids, and sterols, and treat GA through multi-component, multi-pathway, and multi-target mechanisms. Ermiaosan primarily exerts anti-inflammatory effects by inhibiting pathways such as TLR4/nuclear factor kappa-B (NF-κB) or regulating immune responses to reduce the release of inflammatory mediators, while also suppressing xanthine dehydrogenase (XDH) and xanthine oxidase (XO) activity to decrease uric acid production. Sanmiaowan enhance uric acid-lowering and anti-inflammatory effects through the guiding herb Cyathulae Radix, while also protecting cartilage from damage. Simiaowan utilizes Coicis Semen to regulate intestinal flora, alleviate dampness-heat symptoms, and exert multi-pathway anti-inflammatory and uric acid-lowering effects. The active ingredients contribute differently to uric acid metabolism regulation, anti-inflammation, antioxidant activity, and bone repair, resulting in varying therapeutic effects due to differences in formula composition. In summary, formulas derived from Ermiaosan demonstrate significant efficacy in treating dampness-heat type GA. This review summarizes their research progress and mechanisms, providing a reference for clinical application, new drug development, and further studies.

Background/Aims:
Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA.
Methods:
We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021. The primary outcome measure was recurrence-free survival.
Results:
Ninety-two and 33 patients with superficial ESCN underwent ESD and ERFA, respectively. The en bloc, R0, and curative resection rates for ESD were 100.0%, 90.2%, and 76.1%, respectively. At 12 months, the complete response rate was comparable between the two groups (94.6% vs 90.9%, p=0.748). During a median follow-up of 66 months, recurrence-free survival was significantly longer in the ESD group than in the ERFA group (p=0.004), while no significant differences in overall survival (p=0.845) and disease-specific survival (p=0.494) were observed.Preoperative diagnosis of intramucosal cancer (adjusted hazard ratio, 5.55; vs high-grade intraepithelial neoplasia) was an independent predictor of recurrence. Significantly fewer patients in the ERFA group experienced stenosis compare to ESD group (15.2% vs 38.0%, p=0.016).
Conclusions
The risk of recurrence was higher for ERFA than ESD for ESCN but overall survival was not affected. The risk of esophageal stenosis was significantly lower for patients who underwent ERFA.

Objective:
To evaluate the feasibility of dynamic contrast-enhanced MRI (DCE-MRI) in differentiating tumor deposits (TDs) from metastatic lymph nodes (MLNs) in rectal cancer.
Materials and Methods:
A retrospective analysis was conducted on 70 patients with rectal cancer, including 168 lesions (70 TDs and 98 MLNs confirmed by histopathology), who underwent pretreatment MRI and subsequent surgery between March 2019 and December 2022. The morphological characteristics of TDs and MLNs, along with quantitative parameters derived from DCE-MRI (K trans , kep, and v e) and DWI (ADCmin, ADCmax, and ADCmean), were analyzed and compared between the two groups.Multivariable binary logistic regression and receiver operating characteristic (ROC) curve analyses were performed to assess the diagnostic performance of significant individual quantitative parameters and combined parameters in distinguishing TDs from MLNs.
Results:
All morphological features, including size, shape, border, and signal intensity, as well as all DCE-MRI parameters showed significant differences between TDs and MLNs (all P < 0.05). However, ADC values did not demonstrate significant differences (all P > 0.05). Among the single quantitative parameters, v e had the highest diagnostic accuracy, with an area under the ROC curve (AUC) of 0.772 for distinguishing TDs from MLNs. A multivariable logistic regression model incorporating short axis, border, v e, and ADC mean improved diagnostic performance, achieving an AUC of 0.833 (P = 0.027).
Conclusion
The combination of morphological features, DCE-MRI parameters, and ADC values can effectively aid in the preoperative differentiation of TDs from MLNs in rectal cancer.

The general models for intermediates quality analysis in the production process of Yaobitong capsule were established by near infrared spectroscopy (NIRS) combined with chemometrics, realizing the rapid determination of notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, ginsenoside Rd and moisture. The spray-dried fine powder and total mixed granule were selected as research objects. The contents of five saponins were determined by high performance liquid chromatography and the moisture content was determined by drying method. The measured contents were used as reference values. Meanwhile, NIR spectra were collected. After removing abnormal samples by Monte Carlo cross validation (MCCV), Monte Carlo uninformative variables elimination (MC-UVE) and competitive adaptive reweighted sampling (CARS) were used to select feature variables respectively. Based on the feature variables, quantitative models were established by partial least squares regression (PLSR), extreme learning machine (ELM) and ant lion optimization least squares support vector machine (ALO-LSSVM). The results showed that CARS-ALO-LSSVM model had the optimum effect. The correlation coefficients of the six index components were greater than 0.93, and the relative standard errors were controlled within 6%. ALO-LSSVM was more suitable for a large number of samples with rich information, and the prediction effect and stability of the model were significantly improved. The general models with good predicting effect can be used for the rapid quality determination of Yaobitong capsule intermediates.
