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.

OBJECTIVE To promote the standardization of the “Indications” section in package inserts for Chinese patent medicines and ensure rational clinical and patient use. METHODS The “Function and Indications” information of package inserts for Chinese patent medicines was retrieved and collected from the 2020 edition of the Chinese Pharmacopoeia (Volume Ⅰ) and various national and regional standards. Identification criteria were established for syndrome, pathogenesis, disease name, and symptom terminology in the “Indications” section. Microsoft Office Access 2021 was utilized to create query tables for manual extraction of terminological elements, followed by the construction of a three-tier classification system for “Indications” descriptions. A standardized template for “Indications” was developed through quantitative analysis. RESULTS & CONCLUSIONS A total of 9 851 valid package inserts for Chinese patent medicines were included. Among these, the majority (7 991) contained symptom terminology, followed by disease names (5 867) and pathogenesis descriptions (5 167). Within disease name terminology, Western medical disease names predominated (4 446), followed by traditional Chinese medicine disease names (2 018). The “Function and Indications” content of 6 962 package inserts complied with existing requirements. Notably, the secondary classifications of “disease name”, as well as the tertiary classification of “disease name+symptoms” and “symptoms”, failed to meet established standards. Two standardized templates for “Indications” were formulated based on pathogenesis and syndrome:“pathogenesis+disease name+symptoms” and “disease name+syndrome+symptoms”. The “Indications”section should provide complete and accurate information, adhere to standardized formatting, and employ appropriate conjunctions and punctuation. For non-prescription patent medicines, package inserts should be categorized into professional and patient versions. These measures will facilitate the standardization of “Indications” descriptions and advance the overall package inserts for Chinese patent medicines documentation.

Background:
Obesity and chronic pain are related in both directions, according to earlier observational research.This research aimed to analyze the causal association between obesity and chronic pain at the genetic level, as well as to assess whether common factors mediate this relationship.
Methods:
This study used bidirectional two sample Mendelian randomization (MR) technique to analyze the association between obesity and chronic pain. Obesity's summary genome-wide association data were obtained from European ancestry groups, as measured by body mass index (BMI), waist-to-hip ratio, waist circumference (WC), and hip circumference (HC), genome-wide association study data for chronic pain also came from the UK population, including chronic pain at three different sites (back, hip, and headache), chronic widespread pain (CWP), and multisite chronic pain (MCP). Secondly, a two-step MR and multivariate MR investigation was performed to evaluate the mediating effects of several proposed confounders.
Results:
The authors discovered a link between chronic pain and obesity. More specifically, a sensitivity analysis was done to confirm the associations between greater BMI, WC, and HC with an increased risk of CWP and MCP.Importantly, the intermediate MR results suggest that education levels and smoking initiation may mediate the causal relationship between BMI on CWP, with a mediation effect of 23.08% and 15.38%, respectively.
Conclusions
The authors’ findings demonstrate that the importance of education and smoking in understanding chronic pain’s pathogenesis, which is important for the primary prevention and prognosis of chronic pain.

OBJECTIVE To investigate the effects and potential mechanism of paeoniflorin on oxidative stress of ulcerative colitis (UC) mice based on adenosine monophosphate-activated protein kinase (AMPK)/nuclear factor-erythroid 2-related factor 2 (Nrf2) pathway. METHODS Male BALB/c mice were randomly divided into control group, model group, inhibitor group (AMPK inhibitor Compound C 20 mg/kg), paeoniflorin low-, medium- and high-dose groups (paeoniflorin 12.5, 25, 50 mg/kg), high- dose of paeoniflorin+inhibitor group (paeoniflorin 50 mg/kg+Compound C 20 mg/kg), with 8 mice in each group. Except for the control group, mice in all other groups were given 4% dextran sulfate sodium solution for 5 days to establish the UC model. Subsequently, mice in each drug group were given the corresponding drug solution intragastrically or intraperitoneally, once a day, for 7 consecutive days. The changes in body weight of mice were recorded during the experiment. Twenty-four hours after the last administration, colon length, malondialdehyde (MDA) content, and activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in colon tissues were measured; histopathological morphology of colon tissues, tight junctions between intestinal epithelial cells, and histopathological scoring were all observed and evaluated; the mRNA expressions of AMPK and Nrf2, as well as the protein expressions of heme oxygenase-1(HO-1), occludin and claudin-1, were all determined in colon tissue. RESULTS Compared with model group, paeoniflorin groups exhibited recovery from pathological changes such as inflammatory cell infiltration and crypt damage in the colon tissue, as well as improved tight junction damage between intestinal epithelial cells. Additionally, significant increases or upregulations were observed in body weight, colon length, activities of SOD and GSH-Px, phosphorylation level of AMPK, and protein expression of Nrf2, HO-1, occludin, claudin-1, and mRNA expressions of AMPK and Nrf2; concurrently, MDA content and histopathological scores were significantly reduced (P< 0.05 or P<0.01). In contrast, the inhibitor group showed comparable (P>0.05) or worse (P<0.05 or P<0.01) indicators compared to the model group. Conversely, the addition of AMPK inhibitor could significantly reverse the improvement of high- dose paconiflorin (P<0.01). CONCLUSIONS Paeoniflorin can repair intestinal epithelial cell damage in mice, improve tight junctions between epithelial cells, upregulate the expression of related proteins, and promote the expression and secretion of antioxidant-promoting molecules, thereby ameliorating UC; its mechanism may be associated with activating AMPK/Nrf2 antioxidant pathway.

Anti-tumor drug research and development in non-small cell lung cancer (NSCLC) is rapidly developing, and the clinical application of high-throughput sequencing technology is also becoming widespread. Accordingly, researchers are focusing on human epidermal growth factor receptor-2 (HER-2) gene as a rare target of NSCLC, and a series of exploratory studies has been performed. Traditional chemotherapy and immunotherapy are unsatisfactory in the HER-2 mutant population, whereas the survival improvement of anti-HER-2 monoclonal antibodies and pan-HER inhibitors is limited. The development of antibody drug conjugate (ADC) ushers in a turning point for HER-2-mutated NSCLC, and new ADC drugs represented by trastuzumab deruxtecan are making a breakthrough. It opens up a new era of precision therapy for advanced HER-2-mutated NSCLC. Additionally, novel HER-2 inhibitors show very encouraging initial efficacy and safety, and clinical trials are ongoing. This review focuses on the latest progress of research on HER-2-mutated NSCLC.

Immunoglobulin A nephropathy (IgAN) is the primary glomerulonephritis with the highest incidence rate in the world. It is also the main cause of end-stage renal disease (ESRD) in China, which has brought heavy economic burden to the society and patient families. Traditional Chinese medicine (TCM) has certain advantages in treating IgAN. In TCM, IgAN is classified into consumptive disease, hematuria, and edema categories, with the location in the kidney and involving the lung, liver, and spleen. Professor Ren Jixue, a master of TCM, believes that kidney deficiency and spleen deficiency are the root causes of IgAN, and the throat is the source of the disease. He proposed the theory of throat-kidney correlation and used the method of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat to treat IgAN, achieving significant therapeutic effects. Studies have shown that IgAN is closely related to mucosal immune defense. IgAN patients often experience recurrent and gradually worsening symptoms due to mucosal infections, and polymeric Ig receptor (PIgR) is an important component of mucosal defense function. The lack of PIgR leads to the accumulation of IgA molecules in the mucosal lamina propria, and the molecules enter the bloodstream in large quantities and ultimately deposit in the kidneys, causing kidney damage. Complement regulatory protein complement receptor type 1 (CR1) exists on red blood cells and glomeruli and has the function of inhibiting the activation and differentiation of B cells, clearing immune complexes, and inhibiting excessive activation of the complement system. Therefore, regulating the immune defense function through the mucosal-renal axis mediated by PIgR-CR1 will be an important target for preventing and treating IgAN. Based on the theory of throat-kidney correlation, this article explores the effects and molecular mechanisms of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat in preventing and treating IgAN by regulating the mucosal-kidney axis mediated by PIgR-CR1. It provides effective theoretical support and a scientific basis for TCM prevention and treatment of IgAN based on the theory of throat-kidney correlation.

Osteoporosis is a common bone disease, whose incidence is still on the rise, posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress, inflammatory response, and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation, oxidative stress, etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB (NF-κB) ligand (RANKL) pathway, osteoprotegerin (OPG) pathway, Wnt/β-catenin pathway, NF-κB pathway, mitogen-activated protein kinase (MAPK) pathway, adenosine monophosphate (AMP)-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway, and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine, aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.
