ObjectiveTo establish an ultra-performance liquid fingerprint and multi-components determination method for Naomaili granules. To evaluate the quality of different batches by chemometrics, and the anti-neuroinflammatory effects of water extract and main components of Naomaili granules were tested in vitro. MethodsThe similarity and common peaks of 27 batches of Naomaili granules were evaluated by using Ultra performance liquid chromatography (UPLC) fingerprint detection. Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) technology was used to determine the content of the index components in Naomaili granules and to evaluate the quality of different batches of Naomaili granules by chemometrics. LPS-induced BV-2 cell inflammation model was used to investigate the anti-neuroinflammatory effects of the water extract and main components of Naomaili granules. ResultsThe similarity of fingerprints of 27 batches of samples was > 0.90. A total of 32 common peaks were calibrated, and 23 of them were identified and assigned. In 27 batches of Naomaili granules, the mass fractions of 14 components that were stachydrine hydrochloride, leonurine hydrochloride, calycosin-7-O-glucoside, calycosin,tanshinoneⅠ, cryptotanshinone, tanshinoneⅡA, ginsenoside Rb1, notoginsenoside R1, ginsenoside Rg1, paeoniflorin, albiflorin, lactiflorin, and salvianolic acid B were found to be 2.902-3.498, 0.233-0.343, 0.111-0.301, 0.07-0.152, 0.136-0.228, 0.195-0.390, 0.324-0.482, 1.056-1.435, 0.271-0.397, 1.318-1.649, 3.038-4.059, 2.263-3.455, 0.152-0.232, 2.931-3.991 mg∙g-1, respectively. Multivariate statistical analysis showed that paeoniflorin, ginsenoside Rg1, ginsenoside Rb1 and staphylline hydrochloride were quality difference markers to control the stability of the preparation. The results of bioactive experiment showed that the water extract of Naomaili granules and the eight main components with high content in the prescription had a dose-dependent inhibitory effect on the release of NO in the cell supernatant. Among them, salvianolic acid B and ginsenoside Rb1 had strong anti-inflammatory activity, with IC50 values of (36.11±0.15) mg∙L-1 and (27.24±0.54) mg∙L-1, respectively. ConclusionThe quality evaluation method of Naomaili granules established in this study was accurate and reproducible. Four quality difference markers were screened out, and eight key pharmacodynamic substances of Naomaili granules against neuroinflammation were screened out by in vitro cell experiments.

AIM:To investigate the prevalence of visual impairment and its correction status among junior high school students in Xi'an, so as to provide evidence for the development of targeted myopia prevention and control strategies.METHODS: A stratified cluster sampling design was adopted. From March to May 2025, students in grades 7-9 were recruited from three schools in Xi'an, Shaanxi Province, China: Dongfang Middle School, the Middle School Attached to Xi'an University of Technology, and the Xingqing Campus of the High School Affiliated to Xi'an Jiaotong University. In total, 3 974 students were invited, including 1 726 in grade 7, 1 206 in grade 8, and 1 042 in grade 9. The visual acuity was measured monocularly using a 5 m standard logarithmic visual acuity chart, with the fellow eye occluded; the line corresponding to the smallest optotype that could be correctly identified was recorded as the visual acuity value. Non-cycloplegic autorefraction was performed with a desktop autorefractor to obtain spherical equivalent(SE)values for refractive error screening.RESULTS: This study initially included 3 974 students, of whom 32 did not participate in the vision test, resulting in 3 942 students being included in the final analysis. Among them, 3 067(77.80%)were identified with poor vision. The prevalence of myopia was 81.47%(1 746)in males and 87.55%(1 575)in females(P<0.01). A stratified analysis by grade showed myopia rates of 81.72%(1 386)in junior grade one, 84.47%(1 017)in junior grade two, and 88.10%(918)in junior grade three, demonstrating a significant upward trend with increasing grade level(χ2=19.8484, P<0.01). Among the 3 321 myopic students, 2 287 adopted corrective measures. The rates of full correction, under-correction, and non-correction among all myopic students were 48.15%(1 599), 20.71%(688), and 31.14%(1 034), respectively. The rate of non-correction was significantly higher in male students than in females(32.70% vs 29.40%, χ2=4.2222, P<0.05).CONCLUSION: The findings indicate a high prevalence of visual impairment among junior high school students in Xi'an, coupled with suboptimal spectacle-wearing and full-correction rates. There is an urgent need for collaborative efforts across society, schools, and families to implement effective interventions to slow the onset and progression of myopia in this population.

ObjectiveTo investigate the effects and underlying mechanisms of Shenqi Wenfei prescription (SQWF) on chronic obstructive pulmonary disease (COPD). MethodsA rat model of COPD with lung Qi deficiency was established using lipopolysaccharide (LPS) combined with cigarette smoke. Forty-eight SD rats were randomly divided into a blank group, a model group, low-, medium-, and high-dose SQWF groups (2.835, 5.67, 11.34 g·kg-1), and a Yupingfeng group (1.35 g·kg-1). Drug administration began on day 29 after modeling and continued for 2 weeks. The general condition of the rats was observed, and the lung function in each group was assessed. Hematoxylin-eosin (HE) staining was used to observe pathological changes in lung tissue. The proportion of inflammatory cells in bronchoalveolar lavage fluid (BALF) was measured. Apoptosis in lung tissue was examined by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining. The release level of lactate dehydrogenase (LDH) in BALF was detected by a microplate assay. Reactive oxygen species (ROS) levels in lung tissue were detected using fluorescent probes. The levels of malondialdehyde (MDA), total superoxide dismutase (SOD), and reduced glutathione (GSH) in BALF were measured by biochemical methods. Ultrastructural changes in lung cells were observed via transmission electron microscopy. Double immunofluorescence staining was performed to detect the expression of thioredoxin-interacting protein (TXNIP) and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) in lung tissue. Western blot analysis was used to detect the protein expression of TXNIP, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), cysteinyl aspartate-specific protease-1 (Caspase-1), Caspase-1 p20, gasdermin D (GSDMD), GSDMD N-terminal active fragment (GSDMD-N), interleukin-1β (IL-1β), and IL-18 in lung tissue. Serum IL-1β and IL-18 levels were measured by ELISA. ResultsCompared with the blank group, the model group showed lassitude, fatigue, tachypnea, and audible phlegm sounds, and lung function significantly declined (P0.01). Pulmonary emphysema and inflammatory cell infiltration were obvious. The level of inflammatory cells in BALF increased significantly (P0.05). The number of TUNEL-positive cells increased (P0.01). Levels of LDH, ROS, and MDA in BALF increased significantly (P0.01), while GSH and SOD activities decreased significantly (P0.01). Lung tissue cells showed irregular morphology, swollen mitochondria, disrupted cell membranes, and abundant vesicles, i.e., pyroptotic bodies. Protein levels of TXNIP, NLRP3, ASC, Caspase-1, Caspase-1 p20, GSDMD, GSDMD-N, IL-1β, and IL-18 in lung tissue were significantly elevated (P0.01), and serum IL-1β and IL-18 levels also increased significantly (P0.01). Compared with the model group, each medication group showed alleviation of qi deficiency symptoms and improved lung function (P0.01). Pulmonary emphysema and inflammatory cell infiltration were reduced. Inflammatory cell levels decreased (P0.05). The number of TUNEL-positive cells decreased significantly (P0.01). Levels of LDH, ROS, and MDA decreased significantly (P0.05), while GSH and SOD activities significantly increased (P0.01). Morphological and structural damage in lung tissue was improved to varying degrees. Protein levels of TXNIP, NLRP3, ASC, Caspase-1, Caspase-1 p20, GSDMD, GSDMD-N, IL-1β, and IL-18 in lung tissue significantly decreased (P0.01), and serum IL-1β and IL-18 levels also decreased significantly (P0.05). ConclusionSQWF can improve lung function and alleviate inflammatory responses in COPD rats. Its mechanism may be related to regulating the ROS/TXNIP/NLRP3 pathway and inhibiting pyroptosis.

ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction (清肺渗湿汤) combined with western medicine for patients with bronchial asthma of heat wheezing syndrome, and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group, each group with 43 participants. The control group received conventional western medicine, and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group, 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness; secondary outcome measures included traditional Chinese medicine (TCM) syndrome score, asthma control test (ACT) score, pulmonary function indices such as forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), serum inflammatory factor levels including interleukin-4 (IL-4), tumour necrosis factor-α (TNF-α), and high-sensitivity C-reactive protein (hs-CRP), and immune function indices including CD3+, CD4+, CD8+, CD4+/CD8+. All outcome measures were evaluated before and after treatment. Vital signs were monitored, and electrocardiography, blood routine, urine routine, liver function, and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% (39/40), which was significantly higher than that of the control group (85.0%, 34/40, P<0.05). After treatment, both groups showed decreased TCM syndrome scores, IL-4, TNF-α, hs-CRP, and CD8+ levels, as well as increased ACT scores, CD3+, CD4+, CD4+/CD8+, FEV1, FVC, and PEF levels (P<0.05 or P<0.01). Moreover, the improvements in these indices were more significant in the treatment group than in the control group (P<0.05 or P<0.01). No significant abnormalities in safety indicators were observed in either group, and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms, pulmonary function, and clinical effectiveness, with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

Antibody-drug conjugates (ADCs) are a novel class of anti-tumor agents composed of a targeted monoclonal antibody, a cytotoxic drug, and a linker connecting the two. They combine the high specificity of antibodies with the potent cytotoxicity of chemotherapeutic agents. Triple-negative breast cancer (TNBC) is characterized by high aggressiveness, elevated risks of recurrence and metastasis, and poor prognosis, largely due to the lack of effective therapeutic targets. This review summarizes the research progress of ADCs in the treatment of TNBC. It has been found that ADCs targeting human epidermal growth factor receptor 2 (such as trastuzumab deruxtecan), trophoblast cell surface antigen 2 (such as sacituzumab govitecan and datopotamab deruxtecan), zinc transporter LIV-1 (such as ladiratuzumab vedotin), HER-3 (such as patritumab deruxtecan), epidermal growth factor receptor (such as AVID100), and glycoprotein non-metastatic melanoma protein B (such as glembatumumab vedotin) have all demonstrated promising therapeutic effects against TNBC. Despite challenges including acquired resistance and treatment-related toxicities, ADCs are undoubtedly reshaping the therapeutic landscape for TNBC and are expected to occupy a more central position in TNBC treatment in the future.

ObjectiveThe paper aims to investigate the mechanism by which Xiaozheng Zhitong paste (XZP) alleviates bone cancer pain (BCP) through regulating the PTEN-induced putative kinase 1 (PINK1)/Parkin-mediated mitophagy-NOD-like receptor protein 3 (NLRP3) inflammasome pathway to suppress microglial pyroptosis. MethodsLipopolysaccharide (LPS) and LPS-adenosine triphosphate (ATP) were used to establish an inflammation and pyroptosis model in microglial cells. The cells were randomly divided into the following groups: control group, LPS group, LPS+low-dose XZP group, LPS+high-dose XZP group, LPS-ATP group, LPS-ATP+low-dose XZP group, LPS-ATP+high-dose XZP group, LPS-ATP+XZP group, and LPS-ATP+XZP+CsA group. Techniques including terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining, enzyme-linked immunosorbent assay (ELISA), Western blot, and confocal fluorescence staining were employed to assess the effects of XZP on microglial apoptosis, inflammatory cytokine release, inflammasome activation, pyroptosis, and mitophagy. ResultsIn vitro experiments showed that compared with the blank group, the LPS group exhibited significantly increased levels of microglial apoptosis and pro-inflammatory factors interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α)(P<0.01), along with significantly upregulated protein expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and phosphorylated nuclear factor-κB p65 (p-NF-κB p65) (P<0.01). Compared with the LPS group, the high-dose LPS-XZP group significantly reduced the level of apoptosis (P<0.01) and the content of the aforementioned pro-inflammatory factors (P<0.01). Both the low- and high-dose LPS-XZP groups dose-dependently downregulated the protein expression of iNOS, COX-2, and p-NF-κB p65 (P<0.05, P<0.01). Compared with the blank group, the LPS-ATP group showed significantly upregulated expression of pyroptosis-related proteins, including Caspase-1/pro-Caspase-1, N-terminal fragment of gasdermin D (GSDMD-N)/full-length gasdermin D (GSDMD-F), NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), IL-1β precursor (pro-IL-1β), and mature IL-1β (P<0.01). The levels of pyroptotic factors IL-1β and IL-18 were significantly elevated (P<0.01), and membrane pore formation and intracellular reactive oxygen species (ROS) levels were significantly increased (P<0.01). Compared with the LPS-ATP group, both the low- and high-dose LPS-ATP+XZP groups dose-dependently downregulated the expression of the aforementioned pyroptosis-related proteins (P<0.05, P<0.01). The low-dose LPS-ATP+XZP group reduced IL-1β levels (P<0.01), while the high-dose group reduced both IL-1β and IL-18 levels (P<0.01) Both the low- and high-dose LPS-ATP+XZP groups dose-dependently reduced membrane pore formation and intracellular ROS production (P<0.01). Compared with the blank group, the LPS-ATP group showed significantly reduced expression of mitophagy-related proteins PINK1 and Parkin, and a decreased ratio of microtubule-associated protein 1 light chain 3Ⅱ(LC3Ⅱ) to LC3Ⅰ(P<0.01), while p62 expression was significantly increased (P<0.01). Mitochondrial ROS levels were significantly enhanced (P<0.01). Compared with the LPS-ATP group, both the low- and high-dose LPS-ATP+XZP groups dose-dependently reversed the expression of these proteins (P<0.05, P<0.01) and reduced mitochondrial ROS levels (P<0.01). After treatment with the mitophagy inhibitor cyclosporin A (CsA), the beneficial effects of XZP on mitochondrial function and its inhibitory effects on pyroptosis-related protein expression were significantly reversed (P<0.05, P<0.01). ConclusionXZP reduces ROS levels by activating PINK1/Parkin-mediated mitophagy, thereby inhibiting NLRP3 inflammasome activation and microglial pyroptosis, which provides new molecular evidence for the mechanism by which XZP alleviates BCP.

ObjectiveTo investigate the effects and underlying mechanisms of Xiaozheng Zhitong Paste (XZP) on bone cancer pain (BCP). MethodsThirty female BALB/c mice were randomly divided into five groups: a Sham group, a BCP group, a BCP+low-dose XZP group, a BCP+high-dose XZP group, and a BCP+high-dose XZP + protease-activated receptor 2 (PAR2) agonist GB-110 group. BCP mice model was constructed by injecting Lewis lung carcinoma cells into the femoral cavity of the right leg, which was followed by being treated with XZP for 21 d. After 21 d, the mice were sacrificed. Nissl staining was used to evaluate the survival of spinal cord neurons. Immunofluorescence staining was conducted to localize ionized calcium-binding adapter molecule 1 (Iba1) and neuronal nuclear antigen (NeuN) in spinal cord tissue, thereby assessing microglial activation and neuronal survival. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), transforming growth factor-β (TGF-β), interleukin-4 (IL-4), and interleukin-10 (IL-10) in spinal cord tissue. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression levels associated with M1/M2 polarization of microglia. Western blot analysis was performed to examine the expression of proteins related to microglial polarization as well as those involved in the PAR2/nuclear factor kappa B (NF-κB)/NOD-like receptor protein 3 (NLRP3) signaling pathway in the spinal cord. ResultsCompared with the Sham group, the spinal cord neurons were damaged, the number of Nissl-positive spinal cord neurons in the spinal cord tissue was significantly reduced (P<0.01), and the rate of NeuN-positive cells was significantly decreased (P<0.01). The spinal cord microglia were activated, the inflammatory level of the spinal cord tissue was enhanced, and Iba1 staining was significantly enhanced (P<0.01). The levels of IL-1β, TNF-α, IL-6, TGF-β, IL-4 and IL-10 were significantly increased (P<0.01). The mRNA expressions of IL-1β, TNF-α and inducible nitric oxide synthase (iNOS) were significantly increased (P<0.01), and the expression of PAR2, NLRP3, ASC and NF-κB p65 proteins in the spinal cord tissue of the BCP mice was significantly enhanced (P<0.01). Compared with the BCP group, high-dose XZP treatment significantly increased the number of Nissl-positive spinal cord neurons in the BCP mice (P<0.01), significantly enhanced the rate of NeuN-positive cells in the spinal cord tissue, and significantly weakened Iba1 staining (P<0.01). In addition, the levels of IL-1β, TNF-α, and IL-6 were significantly decreased, while the levels of TGF-β, IL-4, and IL-10 were significantly increased (P<0.05, P<0.01). The mRNA expression levels of IL-1β, TNF-α, and iNOS were decreased, whereas those of cluster of differentiation 206 (CD206), arginase-1 (Arg-1), and YM1/2 were significantly increased (P<0.05, P<0.01). Low-dose and high-dose XZP treatment significantly decreased the expression of PAR2, NLRP3, ASC, and NF-κB p65 proteins in the spinal cord tissue (P<0.05, P<0.01). These effects could all be significantly eliminated by the PAR2 agonist GB-110. ConclusionXZP can mitigate BCP in mice, which may be achieved through blocking the activated PAR2/NF-κB/NLRP3 pathway.

Cancer pain is one of the most common complications in patients with malignant tumors, severely affecting their quality of life. Its pathogenesis involves complex interactions among the tumor microenvironment, peripheral sensitization, and central sensitization. The tumor microenvironment initiates peripheral pain sensitization by secreting algogenic mediators, activating ion channels and related receptor signaling pathways, driving abnormal osteoclast activation, and mediating neuro-immune crosstalk. Persistent nociceptive input further triggers increased excitability of central neurons, activation of glial cells, and neuroinflammatory cascade reactions, ultimately leading to central pain sensitization. Although traditional opioid drugs can alleviate pain to some extent, they still have many limitations, such as incomplete analgesia, drug tolerance, and adverse reactions. In recent years, traditional Chinese medicine (TCM) compounds have made continuous progress in the treatment of cancer pain. Studies have shown that they can not only effectively relieve cancer pain and reduce the dosage of opioids but also significantly improve patients' quality of life. TCM treatment of cancer pain follows the principle of syndrome differentiation and treatment. Based on this, targeted therapeutic principles have been proposed, including promoting blood circulation, removing stasis, regulating Qi, and unblocking collaterals; tonifying the kidney, replenishing essence, warming Yang, and dispersing cold, activating blood, resolving phlegm, detoxifying, and dispersing nodules, as well as strengthening the body, replenishing deficiency, and harmonizing Qi and blood. Modern research indicates that TCM compounds can exert synergistic effects through multiple pathways, inhibiting inflammatory responses, regulating nerve conduction, intervening in bone metabolism and related gene expression, thereby producing anti-inflammatory and bone-protective effects to achieve the goal of alleviating cancer pain. This article systematically elaborates on the pathogenesis of cancer pain, the clinical application of TCM in treating cancer pain, and its related mechanisms of action, aiming to provide a theoretical basis and new strategies for the integration of TCM into comprehensive cancer pain management.

Pain, as one of the most common symptoms in cancer patients, seriously affects the survival quality of patients. The three-step pain relief program currently used in clinical practice cannot completely relieve pain in cancer patients and is accompanied by many problems. From the perspective of Jueyin syndrome in traditional Chinese medicine (TCM), this paper believed that the core pathogenesis of cancer pain was declined healthy Qi and cold and heat in complexity, and used Wumeiwan as the main formula with modification according to syndrome for clearing the upper, warming the lower part of the body, and harmonizing the cold and heat. It can regulate the pathological environment of deficiency, cold, stasis, toxicity, and heat, and restore the physiological function of Yang transforming Qi while Yin constituting form, so as to prevent, relieve, and even eliminate cancer pain, having achieved good clinical efficacy. It can not only help cancer patients relieve pain, but also control tumor and eliminate tumor, achieving a dual benefit of pain relief and tumor suppression. It gives full play to the characteristics and advantages of syndrome differentiation and treatment in TCM, and expands the scope of ZHANG Zhongjing's treatment for Jueyin syndrome, which provides ideas for the clinical diagnosis and treatment of cancer pain from the perspective of deficiency-excess in complexity and cold and heat in complexity.
