Premature ovarian insufficiency （POI） is a reproductive endocrine disorder that severely affects female reproductive health. However， there remains a lack of clinically effective and safe therapeutic options to restore ovarian function. Traditional Chinese medicine （TCM）， with its advantages of multi-component and multi-target holistic regulation， has shown unique potential in the prevention and treatment of POI. Among TCM monomers， curcumin， resveratrol， and icariin exert antioxidant， anti-inflammatory， and anti-ovarian granulosa cell apoptosis effects by regulating signaling pathways such as nuclear factor-erythroid 2-related factor 2/heme oxygenase-1， phosphoinositide 3-kinase/protein kinase B， and mitogen-activated protein kinase. Single TCM herbs， including American ginseng， Cuscutae Semen， and Cistanches Herba， can regulate sex hormone levels， and alleviate ovarian oxidative stress and immune damage. TCM compound formulas such as Yijing decoction， Siwu decoction， Zuogui pill， and Kuntai capsule modulate multiple signaling pathways， including vascular endothelial growth factor/vascular endothelial growth factor receptor-2， phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin， and silence information regulator 1/p53， thereby promoting angiogenesis， inhibiting mitochondrial apoptosis， and regulating autophagy and ferroptosis， which ultimately delay follicular atresia and improve ovarian reserve function. Further studies are suggested to apply artificial intelligence to deeply explore the underlying mechanisms and carry out high-quality clinical trials， so as to promote the standardized application of TCM in the prevention and treatment of POI.

Sanhuang Xiexintang （SHXXT）， originating from the Synopsis of the Golden Chamber （Jin Gui Yao Lue）， comprises three medicinal herbs： Rhei Radix et Rhizoma， Coptidis Rhizoma， and Scutellariae Radix. Renowned for its effects of purging fire， detoxifying， drying dampness， and draining heat， SHXXT primarily treats syndromes characterized by internal excess heat， dampness-heat stagnation， and reckless blood movement due to heat. Because of the concise formulation and remarkable efficacy of this formula， modern research has extensively explored the chemical composition， clinical applications， and pharmacological mechanisms of SHXXT， yielding significant advancements. As a modern derivative of SHXXT， Yiqing granules exemplify the transformation of classical formulas into convenient and precise applications， embodying the paradigm of modern development of classical formulas. This systematic review synthesizes recent research progress in SHXXT. Chemical analyses reveal that the active components—anthraquinones， alkaloids， and flavonoids—of SHXXT exert holistic therapeutic effects through multi-component synergy. Clinical studies demonstrate broad utility of this formula in managing digestive disorders， endocrine diseases， urinary tract infections， dermatological conditions， and systemic inflammatory diseases， highlighting its multi-system regulatory potential. Mechanism investigations elucidate its multi-target mechanism of action， including antimicrobial， anti-inflammatory， metabolic-regulatory， hepatoprotective， and gastrointestinal-modulating effects， reflecting an integrated multi-component， multi-target， multi-pathway mode of action. This review systematically summarizes the modern research progress in SHXXT， providing a theoretical foundation for deciphering the scientific essence of classical formulas and advancing their precision application in clinical practice.

OBJECTIVE To predict and verify the mechanism of Jiawei qifang weitong granule in ameliorating precancerous lesions of gastric cancer （PLGC）. METHODS Transcriptomic data of PLGC-related were obtained from the GEO database to screen differentially expressed genes and conduct functional enrichment analysis. Targets related to gastric mucosal injury repair were screened via the GeneCards database. The active ingredient targets of Jiawei qifang weitong granule were predicted using the TCMSP and other databases. The intersection of differentially expressed genes， gastric mucosal repair targets and active ingredient targets was extracted. A protein-protein interaction network was constructed based on the STRING database， and the top 6 hub target genes with the highest connectivity were screened. A PLGC rat model was established by combining 1-methyl-3-nitro-1-nitrosoguanidine with alternating fasting and full feeding. Model rats were divided into model group， weifuchun group （positive control， 0.40 g/kg）， low-， medium- and high-dose Jiawei qifang weitong granule groups （9.73， 19.44， 38.90 g/kg）， with 10 rats in each group. Another 10 unmodeled rats were set as control group. Rats in each group were intragastrically administered corresponding liquid medicine or normal saline once a day for 30 consecutive days. After the last administration， pathological morphological changes of rat gastric tissues were observed， and the mRNA expression levels of hub target genes as well as partial protein expression levels in gastric tissues were detected. RESULTS Transcriptomics and network pharmacology analyses revealed that the top 6 hub target genes ranked by connectivity included MMP9 （matrix metalloproteinase 9）， BCL2（B-cell lymphoma 2）， IL10（interleukin 10），ICAM1（intercellular adhesion molecule 1）， PTGS2 （prostaglandin-endoperoxide synthase 2）， and HIF1A （hypoxia-inducible factor 1α subunit）. Animal experiments showed that compared with the model group， gastric mucosal pathological injury was significantly alleviated in medium- and high-dose Jiawei qifang weitong granule groups and weifuchun group. The pathological injury score of gastric mucosa， the mRNA expression levels of MMP9， PTGS2， ICAM1， BCL2 and HIF1A， as well as the protein expression levels of PTGS2 and BCL2 in gastric tissues were significantly decreased （P＜0.05）， while the mRNA expression level of IL10 was significantly increased （P＜0.05）. CONCLUSIONS Jiawei qifang weitong granule may ameliorate PLGC by targeted down-regulating the mRNA expression of MMP9， PTGS2， ICAM1， BCL2 and HIF1A， up-regulating IL10 mRNA expression， and regulating the imbalance between gastric mucosal inflammatory response and injury repair.

ObjectiveTo investigate the therapeutic effect of paeoniflorin on metabolic dysfunction-associated fatty liver disease （MASLD） combined with insulin resistance （IR）， and to elucidate its regulatory mechanisms on the Toll-like receptor 4 （TLR4）/nuclear transcription factor （NF）-κB-insulin receptor substrate 1 （IRS1） inflammation-insulin signaling axis. MethodsMASLD mouse model was established using a 60% high-fat diet. Mice were randomly assigned to a normal control group， a MASLD model group， and paeoniflorin groups （low dose： 25 mg·kg^-1·d^-1， medium dose： 50 mg·kg^-1·d^-1， high dose： 100 mg·kg^-1·d^-1）， receiving intragastric administration for consecutive 12 weeks. Concurrently， a palmitic acid/oleic acid （PA/OA）-induced lipid deposition model was established in HepG2 cells. Cell counting kit-8 （CCK-8） assay was performed to determine the optimal concentrations of PA/OA and paeoniflorin for intervention. Mice body weight， liver index， and serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， triglycerides （TG）， and total cholesterol （TC） were measured. Fasting blood glucose （FBG） and fasting insulin （FINS） levels were measured， and the homeostatic model assessment of insulin resistance （HOMA-IR） was calculated， while an oral glucose tolerance test （OGTT） was performed to evaluate glucose metabolism. Hematoxylin and eosin （HE） staining was used to observe pathological changes and inflammatory cell infiltration in liver tissue， and oil red O staining was used to evaluate lipid droplet deposition in liver tissue and HepG2 cells. Potential targets were screened using network pharmacology and molecular docking. Western blot analysis was performed to detect the expression of HSP90AA1， TLR4， p-NF-κB p65， p-IRS1， and p-Akt proteins in liver tissue and HepG2 cells. ResultsCompared with the normal control group， mice in the MASLD model group exhibited significantly increased body weight， liver index， and serum levels of ALT， AST， TG， and TC， as well as markedly elevated FBG， FINS， and HOMA-IR， and impaired glucose tolerance （P<0.01）. HE staining revealed marked hepatic steatosis and inflammatory cell infiltration， while oil red O staining showed a significant increase in lipid droplet deposition. Compared with the MASLD model group， after intervention with various doses of paeoniflorin， the increase in body weight and liver index was reduced， serum ALT， AST， TG， and TC levels decreased， and FBG， FINS， and HOMA-IR were significantly lowered， with glucose tolerance markedly improved （P<0.05， P<0.01）， showing a certain dose-dependent trend. HE and oil red O staining results showed a marked reduction in hepatic steatosis and lipid deposition. In vitro experiments demonstrated that， compared with the control group， PA/OA treatment significantly induced increased lipid deposition in HepG2 cells. Compared with the model group， paeoniflorin intervention significantly reduced intracellular lipid droplets， and lipid deposition showed a dose-dependent decreasing trend. Mechanism studies indicated that， compared with the normal control group， the MASLD model group exhibited significantly elevated expression of TLR4， HSP90AA1， and p-NF-κB p65， while p-IRS1 （Ser307） expression was elevated and p-Akt （Ser473） expression was reduced （P<0.01）. Compared with the model group， the expression of the aforementioned proteins was significantly reversed in all treatment groups following intervention （P<0.05， P<0.01）. ConclusionPaeoniflorin significantly alleviates lipid deposition and insulin resistance in MASLD mice. Its mechanism of action may involve targeting HSP90AA1， TLR4， and NF-κB1 to regulate the TLR4/NF-κB-IRS1 inflammation-insulin signaling axis. This regulation suppresses inflammatory responses and restores insulin signaling， thereby ameliorating abnormalities in glucose and lipid metabolism.

Objective:To investigate the effect of dandelion polysaccharide(DP)on inflammatory response and the protein expression of S100 calcium binding protein A8/A9(S100A8/A9)in lung tissue and small intestinal tissue of rats with multiple organ dysfunction syndrome(MODS).Methods:The two-hit method of hemorrhagic shock and intraperitoneally injected lipopolysaccharide was used to establish a rat model of MODS,and the rats were divided into sham-operation group,model group,low-dose DP group,and high-dose DP group.The organ coefficient and wet/dry weight ratio of the lung and the small intestine were observed for each group of rats;HE staining was used to observe the pathomorphological changes of lung tissue and small intestinal tissue;immunohistochemical staining was used to measure the expression of interleukin-1β(IL-1β),interleukin-6(IL-6),and interleukin-10(IL-10)in lung tissue and small intestinal tissue;Western blot was used to measure the protein expression level of S100A8/A9 in lung tissue and small intestinal tissue.Results:Compared with the sham-operation group,the model group had significant increases in the organ coefficient of the lung(5.849±0.824),the wet/dry weight ratio of the lung(6.556±0.631),the wet/dry weight ratio of the small intestine(6.356±0.535),and the wet weight/length ratio of the small intestine(73.950±5.569).HE staining showed that that the model group had massive in-flammatory cell infiltration in alveolar space and pulmonary interstitium,thickened alveolar wall,and disintegration and fragmentation of the villi of the small intestine,with inflammatory cell infiltration and proliferation of segmental aggregated lymphoid follicles.In the model group,S100A8/A9 was mainly expressed in neutrophils and macrophages,and there were increases in the expression of S100A8/A9,IL-1β,and IL-6 and a reduction in the expression of IL-10 in the lung tissue and small intestinal tissue of rats.After treatment with high-dose DP,there were reductions in the organ coefficient of the lung(4.297±0.462),the wet/dry weight ratio of the lung(5.313±0.495),the wet/dry weight ratio of the small intestine(5.398±0.388),and the wet weight/length ratio of the small intestine(59.417±2.891).The high-dose group also had alleviation of pathological injury in the small intestine,with reductions in the expres-sion of S100A8/A9,IL-1β,and IL-6 and an increase in the expression of IL-10 in lung tissue and small intestinal tissue.Conclusion:DP may alleviate inflammatory response in lung and small intestinal injuries of rats with MODS by inhibiting the expression of S100A8/A9.

ObjectiveTo characterize the seasonal patterns of influenza in Kunming City, Yunnan Province before, during, and after the COVID-19 pandemic, and provide scientific evidence for optimizing influenza prevention and control strategies. MethodsInfluenza-like illness (ILI) and etiological surveillance data for influenza from the 14^th week of 2010 to the 13^th week of 2024 in Kunming City of Yunnan Province were collected. Harmonic regression models were constructed to analyze the epidemic characteristics and seasonal patterns of influenza before (2010/2011‒2019/2020 influenza seasons), during (2020/2021‒2022/2023 influenza seasons), and after (2023/2024 influenza season) the COVID-19 pandemic. ResultsBefore the COVID-19 pandemic, influenza in Kunming City mainly exhibited an annual cyclic pattern without a significant semi-annual periodicity, peaking from December to February of the next year, with an epidemic duration of 20‒30 weeks. During the pandemic, influenza seasonality shifted, with an increase in semi-annual periodicity and an approximate one month delay in annual peaks. However, after the pandemic, the annual amplitude of influenza increased compared with that before the pandemic, and the epidemic duration extended by about one month. Although the annual peak largely reverted to the pre-pandemic levels, the annual peaks for different influenza subtypes/lineages had not fully recovered. ConclusionInfluenza seasonality in Kunming City underwent substantial alterations following the COVID-19 pandemic and has not yet fully reverted to pre-pandemic levels. Continuous surveillance on different subtypes/lineages of influenza viruses remains essential, and prevention and control strategies should be adjusted and optimized in a timely manner based on current epidemic trends.

Objective To investigate the correlation between apathy and imaging markers in pa-tients with aCSVD.Methods A total of 143 patients diagnosed with aCSVD and hospitalized in the Department of Neurology of the First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology from August 2023 to August 2024 were continu-ously included as the study objects.According to MAES,they were divided into an apathetic group(MAES score＞14,68 cases)and a non-apathetic group(MAES score ≤14,75 cases).The clinical data and imaging markers were compared between the two groups.Results The apathetic group had significantly older age and larger ratio of hypertension,but shorter years of education and lower MAES score than the non-apathetic group(P＜0.05,P＜0.01).The apathetic group also had notably higher Fazekas score of white matter hyperintensity(WMH),larger recent small sub-cortical infarct(RSSI),lacunar infarct(LI),and perivascular space(PVS)in the basal ganglia and the centrum semiovale,more obvious cerebral atrophy and cerebral microbleed(CMB),and high-er total imaging burden score when compared with the non-apathetic group(P＜0.01).In the aCSVD patients,the MAES score was positively correlated with WMH Fazekas score,RSSI,LI,basal ganglia PVS,centrum semiovale PVS,cerebral atrophy,CMB,and total imaging burden score(P＜0.01).WMH Fazekas score was an independent risk factor for apathy in the aCSVD patients(OR=2.218,95％CI:1.343-3.664,P=0.002).Conclusion The higher the score of ima-ging markers in patients with aCSVD,the more severe the apathy.

Objective To investigate the risk factors for stroke-associated pneumonia(SAP)in patients with acute anterior circulation large-vessel occlusion stroke after endovascular treatment(EVT).Methods A total of 115 patients with acute anterior circulation large-vessel occlusion stroke who received EVT in the Department of Neurology,The First Affiliated Hospital of Xi'an Jiaotong University,from March 2022 to May 2023 were continuously included.Their clinical data were retrospectively collected.The patients were divided into SAP group(55 cases)and non-SAP group(60 cases)according to the occurrence of SAP after the operation.Differences in baseline data,surgical and perioperative indicators were compared between the two groups,and the risk factors for SAP after EVT were analyzed using the multivariate Logistic regression analysis.Results Univariate analysis showed there were significant differences in the Glasgow Coma Scale(GCS)score and the National Institute of Health Stroke Scale(NIHSS)score at admission,incidence of dysphagia,duration of the surgery,proportion of general anesthesia,rate of unsuccessful vascular recanalization and the rate of immediate CT high-density sign between SAP group and non-SAP group(all P＜0.05).Multivariate Logistic regression analysis of the above indicators showed that duration of the surgery(OR=1.014,95％CI:1.001-1.028,P＜0.05),dysphagia(OR=6.137,95％CI:1.694-22.232,P＜0.01)and unsuccessful vascular recanalization(OR=6.043,95％CI:1.062-34.382,P＜0.05)were independent risk factors for SAP after EVT.Conclusion Long duration of EVT,dysphagia and unsuccessful vascular recanalization are directly related to the occurrence of SAP after EVT in patients with acute anterior circulation large-vessel occlusive infarction.Therefore,targeted measures should be taken as soon as possible to reduce the incidence of SAP after EVT and thus improve the clinical prognosis of these patients.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.
