ObjectiveTo explore the potential mechanism of Xiaoqinglongtang(XQL) in the prevention and treatment of high altitude pulmonary edema(HAPE) by network pharmacology, molecular docking, and molecular dynamics simulation, and to verify it by in vivo animal model. MethodsIn this study, the active ingredients, drug targets, and HAPE-related targets of XQL were collected from BATMAN-TCM, GeneCards, and Online Mendelian Inheritance in Man(OMIM) databases. The protein-protein interaction(PPI) network was constructed by using intersection targets, and the core targets were screened and visualized by Cytoscape software. Functional annotation and pathway analysis of the intersection targets were performed by gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) functional enrichment. AutoDock and GROMACS were used to evaluate the binding ability of active ingredients to key targets. In the experimental verification part, a mouse model of HAPE induced by hypobaric hypoxia(simulated 6 000 m altitude for 48 h) was established. The control effect was evaluated by hematoxylin-eosin(HE) staining, lung tissue water content, lung tissue wet/dry weight ratio, real-time quantitative polymerase chain reaction(Real-time PCR) detection of gene expression levels, and immunohistochemistry and Western blot detection of key protein expression. ResultsA total of 355 active ingredients of XQL, 2 142 targets, 716 HAPE-related targets, and 236 intersection targets were obtained by network pharmacology analysis. Key core targets such as interleukin (IL)-6, tumor necrosis factor (TNF), protein kinase B1 (Akt1), and hypoxia-inducible factor-1α (HIF-1α) were screened. The results of GO analysis of common targets involved 738 biological processes(BP), 72 cellular components(CC), and 135 molecular functions(MF). KEGG analysis effectively enriched two important signaling pathways: Phosphoinositol 3-kinase (PI3K)/Akt and HIF-1α. The results of molecular docking and molecular dynamics simulation showed that the screened active ingredients had good binding ability with key targets. In the HAPE model induced by hypobaric hypoxia(6 000 m, 48 h), the lung tissue water content, lung tissue wet/dry weight ratio, and pathological injury score of the model group were significantly increased(P<0.01), accompanied by exudation of a large number of red blood cells in the alveoli and alveolar interstitium, a significant increase in inflammatory cells, a significant widening of the alveolar septum, and mutual fusion between the alveoli. The XQL administration group significantly improved the above pathological changes(P<0.01). The results of inflammatory factor expression showed that compared with the control group, the model group showed significantly up-regulated expression of TNF-α, IL-6, and IL-1β in the lung tissue(P<0.01). Compared with the model group, the XQL administration group had significantly decreased expression of inflammatory factors(P<0.05, P<0.01). The mRNA expression of key pathway related genes PI3K, Akt1, mammalian target of rapamycin(mTOR), and HIF-1α was significantly increased in the model group(P<0.01), and decreased in a concentration-dependent manner after XQL administration(P<0.05, P<0.01). The expression levels of key proteins PI3K, phosphorylation(p)-PI3K, Akt1, p-Akt1, mTOR, p-mTOR, and HIF-1α in lung tissue were analyzed by immunohistochemistry and Western blot. Compared with the blank group, the model group showed increased expression of key proteins(P<0.05, P<0.01). Compared with the model group, the XQL administration group exhibited decreased expression of key proteins(P<0.05, P<0.01). ConclusionXQL can reduce lung inflammation and improve HAPE. The mechanism may be related to the regulation of PI3K/Akt/mTOR and HIF-1α pathways. This study provides a new idea and a theoretical basis for the treatment of HAPE with XQL.

ObjectiveTo investigate the effect of Tougu Xiaotong capsules (TGXTC) on the regulation of chondrocyte PANoptosis, delay of chondrocyte degeneration, and improvement of the symptoms in knee osteoarthritis (KOA). MethodsIn vivo experiments: 50 male C57BL/6 mice were randomly assigned into five groups (n=10 per group): sham operation group, model group, low-dose TGXTC group (7.2 g·kg-1), high-dose TGXTC group (14.4 g·kg-1), and diclofenac sodium group (0.05 g·kg-1). Except for the sham group, KOA models were established in all other groups using the modified Hulth method. Following successful model induction, the TGXTC groups received daily oral gavage of 7.2 or 14.4 g·kg-1 for 6 weeks, while the diclofenac sodium group received 0.05 g·kg-1 solution daily over the same duration. Model evaluation was performed using Lequesne MG score; micro-computed tomography (micro-CT) was used to scan the knee, hematoxylin-eosin (HE) staining and safranin O-fast green staining were used to observe the morphology of cartilage, transmission electron microscopy (TEM) was used to determine ultrastructural changes of PANoptosis. Multiple immunofluorescence (IF) co-localization assays was performed to detect the co-localization of cleaved Caspase-3, receptor-interacting protein 3 (RlPK3), and the N-terminal domain of gasdermin D (GSDMD-N) in cartilage tissue, while western blot was employed to detect the expression levels of cleaved Caspase-3, RIPK3, and GSDMD-N. In vitro experiments: The knee cartilages of 4-week-old SD rats were isolated, and a chondrocyte in vitro culture system was established through mechanical digestion with 0.2% type Ⅱ collagenase. Second-generation chondrocytes were divided into three groups: the control group, the model group (pretreated with 10 mg·L-1 lipopolysaccharide (LPS) for 24 h followed by treatment with 1 μmol·L-1 nigericin for 4 h), and the TGXTC treatment group (pretreated with 10 mg·L-1 LPS for 24 h, followed by exposure to 1 μmol·L-1 nigericin for 4 h and subsequently treated with 100 mg·L-1 TGXTC for an additional 24 h). The levels of reactive oxygen species (ROS), apoptosis, necroptosis, and pyroptosis of chondrocytes were evaluated via fluorescence microscopy following staining with ROS detection, AO/EB and YO-PRO-1/PI staining kits. Transmission electron microscopy was utilized to investigate the ultrastructural changes associated with PANoptosis in cartilage tissue of KOA mice. Inflammatory cytokine levels (IL-1β and IL-18) were measured using ELISA. Western blot was conducted to assess protein expressions related to PANoptosis, including cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3. ResultsCompared with the sham group, the Lequesne MG scores were significantly up-regulated(P<0.01) in the model group, and the pathological changes of cartilage were significantly, with joint spaces narrower, osteophyte formation increased, secere abrasion of cartilage surface. Ultrastructural analysis revealed pronounced chondrocyte apoptosis, necroptosis, and pyroptosis, along with markedly elevated expression of cleaved Caspase-3, RlPK3, and GSDMD-N in cartilage tissue (P<0.01). In addition, The mean fluorescence intensities of ROS, orange-red fluorescence in AO/EB staining, green fluorescence and red fluorescence in YO-PRO-1/PI staining were increased of chondrocyte in the model group (P<0.01) . The levels of inflammatory factors IL-1β and IL-18 in the supernatant were increased (P<0.01). The expression of PANoptosis related proteins (cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3) were also significantly upregulated(P<0.05). Compared to the model group, the TGXTC group demonstrated a significant improvement in various parameters of mice. These included a reduction in the Lequesne MG score, an increase in joint space, a decrease in osteophyte formation, diminished cartilage damage, reduced release of ROS, and alleviation of apoptotic, necroptotic, and pyroptotic processes in chondrocytes. Additionally, mitochondrial swelling and endoplasmic reticulum dilation were also mitigated. The levels of ROS as well as IL-1β and IL-18 were significantly decreased (P<0.05). Furthermore, the expression levels of proteins associated with PANoptosis in cartilage tissue showed marked reductions (P<0.05). Similar results were observed in chondrocytes: cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3 exhibited significant decreases as well (P<0.05). ConclusionTGXTC may mitigate chondrocytes degeneration and alleviate KOA symptoms by reducing oxidative stress and suppressing the activation of PANoptosis pathways.

The theory of constitution in traditional Chinese medicine (TCM) has emerged as a new discipline in recent years. Constitution plays a vital role in the onset,progression,transformation,and prognosis of diseases. At present,some clinical scholars have adopted a novel diagnostic and treatment model of "constitution differentiation-disease identification-syndrome differentiation",in which constitution is regarded as a core element throughout the diagnostic and therapeutic process. Constitution is closely associated with etiology,onset,pathogenesis,syndrome differentiation,and treatment. Against this background,the construction of animal models based on constitution holds far-reaching significance for advancing clinical research. This paper focuses on the construction and evaluation of rodent models with Qi-deficiency constitution,aiming to explore how to further induce Qi-deficiency syndromes and related disease states on the basis of Qi-deficiency constitution models,thereby developing an integrated animal model that embodies the trinity of "constitution-disease-syndrome". The establishment of this model not only provides a solid experimental foundation for the development of new therapies and drugs in TCM targeting specific constitutions,diseases,and syndromes,but also greatly promotes the modernization and scientific advancement of TCM theory. By comprehensively applying multidisciplinary technologies and methods,the study evaluates the model's validity,reliability,and practicality,with the aim of opening new avenues for future research in TCM and promoting the development of the field.

Chronic heart failure (CHF) is an end-stage cardiac syndrome driven by multiple factors. Its pathological process involves interactions of multiple pathways such as energy metabolism dysfunction, neuroendocrine dysregulation, and myocardial fibrosis. Although current clinical medicine can alleviate symptoms through single-target approaches, significant limitations in reversing cardiac remodeling and disease progression remain. Puerarin, a major bioactive isoflavone constituent derived from Pueraria lobata, exhibits multidimensional pharmacological effects, such as vasodilatory effects, regulation of neuroendocrine balance, enhancement of metabolic homeostasis, and suppression of myocardial apoptosis. This review systematically integrated puerarin's multi-target regulatory network, elucidating its mechanisms such as improving energy metabolism by AMP-activated protein kinase/mechanistic target of rapamycin (AMPK/mTOR) pathway, inhibiting fibrosis mediated by transforming growth factor-β (TGF-β)/Smad signals, and attenuating oxidative-inflammatory cascades by regulating nuclear factor erythroid 2 (E2)-related factor 2/nuclear transcription factor-κB(Nrf2/NF-κB) axis. Clinical research data was used to validate its efficacy in improving the left ventricular ejection function and reducing the therapeutic potential of cardiovascular events' risks. The study proposed that puerarin's "systemic regulation" characteristic breaks through the limitations of traditional single-target drugs and prospected its clinical translation pathway based on metabolomics and nano-delivery technology, offering an integrative perspective from molecular mechanisms to precise therapy for the research on modernization of traditional Chinese medicine.

AIM:To evaluate visual outcomes and visual function in nonamblyopic adults with myopic anisometropia treated with small incision lenticule extraction(SMILE).METHODS:Prospective comparative cohort study. The consecutive patients who underwent SMILE for the treatment of myopia or myopic astigmatism at Zhongshan Ophthalmic Center(Guangzhou, China)between October 2015 and January 2016 were included. They were divided into two groups based on the bilateral difference of a spherical equivalent(SE)refraction ≥1.50 D: the anisometropic myopia group(interocular SE difference ≥1.50 D)and non-anisometropic myopia group(interocular SE difference<1.50 D). Refractive status, uncorrected and corrected distance visual acuity(UDVA and CDVA), and visual function parameters including fusional vergence amplitude, stereoacuity and horizontal phoria were measured preoperatively and at 1 wk,1,3 and 6 mo after surgery.RESULTS:A total of 49 cases(98 eyes)were included in the study, and 19 cases(38 eyes)in the anisometropic group, including 11 males and 8 females, with a mean age of 25.4±6.2 y, and 30 cases(60 eyes)in the non-anisometropic myopia group, including 19 males and 11 females, with a mean age of 26.8±4.6 y. The CDVA of the non-anisometropia group was significantly better than that of the anisometropia group 6 mo postoperatively(P=0.036). However, the safety and efficacy indexes of the two groups did not show significant differences. The fusional vergence(break point and recovery point)of the anisometropia group decreased(P=0.005 and P=0.03)and was significantly lower than that in the non-anisometropia group at 6 mo post operatively(P=0.029 and P=0.046). Both groups showed a significant improvement in distance and near stereopsis at 1, 3 and 6 mo in comparison with the preoperative baseline and 1 wk postoperatively(all P<0.05). No clinically significant change in the amount of ocular alignment in terms of distance and near deviation postoperatively in either groups.CONCLUSION: SMILE is a predictable, effective, and safe method for correcting myopic anisometropia in adults without amblyopia. Although the fusional vergence amplitudes changed, stereopsis can be improved after surgery.
