Traditional Chinese medicine and its bioactive components have garnered increasing attention as potential therapeutic options for allergic asthma. By targeting the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway, these natural compounds exhibit unique advantages in multilevel immunomodulation and inflammation suppression compared with single-target synthetic drugs. Accumulating pharmacological evidence supports their capacity to restore pathway homeostasis, positioning them as promising candidates for complementary strategies in asthma management. Allergic asthma, a heterogeneous respiratory disorder affecting approximately 150 million individuals worldwide, arises from a complex interplay of genetic predisposition, environmental exposures, and lifestyle factors. Its pathological progression is marked by aberrant activation of the PI3K/AKT signaling cascade, with the mechanistic target of rapamycin serving as a key downstream regulatory node. This evolutionarily conserved pathway orchestrates fundamental cellular processes that contribute to three hallmark pathological features of allergic asthma: chronic airway inflammation, structural remodeling of the bronchial architecture, and airway hyperresponsiveness. This review has 3 primary objectives: (1) to evaluate the role of the PI3K/AKT pathway in allergic asthma pathogenesis, (2) to analyze the molecular mechanisms of representative traditional Chinese medicine preparations and their active ingredients, and (3) to identify novel bioactive inhibitors derived from natural products. Collectively, these investigations provide a conceptual framework for the development of next-generation targeted therapies and for optimizing clinical management strategies for allergic asthma.

With the increasing use of low-dose computed tomography (LDCT) in lung cancer screening and health examinations, the clinical goal of pulmonary nodule management has shifted from detecting nodules to identifying lesions that warrant intervention while avoiding overdiagnosis and overtreatment of low-risk disease. Artificial intelligence (AI) has consequently evolved from computer-aided detection and segmentation to benign-malignant differentiation, longitudinal growth assessment, invasiveness prediction, risk stratification, and closed-loop workflow support. This review outlines the developmental trajectory of AI for pulmonary nodules and summarizes advances in detection and segmentation, radiomics, end-to-end deep learning, longitudinal modeling, and multimodal integration across incidentally detected, screening-detected, subsolid, and multiple-nodule scenarios. Particular attention is given to real-world failure modes and their causes, including data and label bias, scanner- and protocol-related distribution shift, spectrum bias and overfitting in subsolid nodules, missed atypical lesions, automation bias, and management of discordance between AI outputs and guideline-based recommendations. Current evidence suggests that AI may improve detection efficiency and risk reclassification in selected settings; however, evidence regarding cross-population calibration, patient-relevant outcomes, cost-effectiveness, and post-deployment monitoring remains limited. AI should therefore be positioned as a human-in-the-loop adjunct within guideline-governed pathways, supported by scenario-specific validation, transparent reporting, interpretability and accountability, continuous performance auditing, and multidisciplinary decision-making.

[Objective] To analyze the loss rate of platelet donors and evaluate the strategies for establishing a platelet donor bank. [Methods] A total of 1 443 donors who joined the HLA and HPA gene donor bank for platelets in Henan Province from 2018 to 2020 were included in this study. Data on the total number of apheresis platelet donations, annual donation frequency, age at enrollment, donation habits (including the number of platelets donated per session and whether they had previously donated whole blood), and enrollment location were collected from the platelet donor information management system. Donor loss was determined based on the date of their last donation. The loss rates of different groups under various conditions were compared to assess the enrollment strategies. [Results] By the time the platelet bank was officially operational in 2022, 421 donors had been lost, resulting in an loss rate of 29% (421/1 443). By the end of 2023, the overall cumulative loss rate reached 52% (746/1 443). The loss rate was lower than the overall level in groups meeting any of the following conditions: total apheresis platelet donations exceeding 50, annual donation frequency of 10 or more, age at enrollment of 40 years or older, donation of more than a single therapeutic dose per session, or a history of whole blood donation two or more times. Additionally, loss rates varied across different enrollment locations, with higher enrollment numbers generally associated with higher loss rates. [Conclusion] Through a comprehensive analysis of donor loss, our center has adjusted its strategies for establishing the donor pool. These findings also provide valuable insights for other blood collection and supply institutions in building platelet donor banks.

ObjectiveTo construct a large language model (LLM)-based intelligent pre-consultation system for traditional Chinese medicine (TCM) to improve efficacy of clinical practice. MethodsA TCM large language model was fine-tuned using DeepSpeed ZeRO-3 distributed training strategy based on YAYI 2-30B. A weighted undirected graph network was designed and an agent-based syndrome differentiation model was established based on relationship data extracted from TCM literature and clinical records. An agent collaboration framework was developed to integrate the TCM LLM with the syndrome differentiation model. Model performance was comprehensively evaluated by Loss function, BLEU-4, and ROUGE-L metrics, through which training convergence, text generation quality, and language understanding capability were assessed. Professional knowledge test sets were developed to evaluate system proficiency in TCM physician licensure content, TCM pharmacist licensure content, TCM symptom terminology recognition, and meridian identification. Clinical tests were conducted to compare the system with attending physicians in terms of diagnostic accuracy, consultation rounds, and consultation duration. ResultsAfter 100 000 iterations, the training loss value was gradually stabilized at about 0.7±0.08, indicating that the TCM-LLM has been trained and has good generalization ability. The TCM-LLM scored 0.38 in BLEU-4 and 0.62 in ROUGE-L, suggesting that its natural language processing ability meets the standard. We obtained 2715 symptom terms, 505 relationships between diseases and syndromes, 1011 relationships between diseases and main symptoms, and 1 303 600 relationships among different symptoms, and constructed the Agent of syndrome differentiation model. The accuracy rates in the simulated tests for TCM practitioners, licensed pharmacists of Chinese materia medica, recognition of TCM symptom terminology, and meridian recognition were 94.09%, 78.00%, 87.50%, and 68.80%, respectively. In clinical tests, the syndrome differentiation accuracy of the system reached 88.33%, with fewer consultation rounds and shorter consultation time compared to the attending physicians (P<0.01), suggesting that the system has a certain pre- consultation ability. ConclusionThe LLM-based intelligent TCM pre-diagnosis system could simulate diagnostic thinking of TCM physicians to a certain extent. After understanding the patients' natural language, it collects all the patient's symptom through guided questioning, thereby enhancing the diagnostic and treatment efficiency of physicians as well as the consultation experience of the patients.

ObjectiveTo investigate the mechanism of kidney-tonifying and liver-regulating cyclical therapy and its formula in regulating endometrial receptivity during the "implantation window" in rats with polycystic ovary syndrome (PCOS). MethodsSix rats were randomly selected from 36 SPF SD female rats as the normal group, and the remaining rats were administered letrozole to induce a PCOS model. By using a random number method, the rats were divided into the following groups: normal group, model group, Xiaoyaosan group (11.97 g·kg-1), Sanzi Yangmo decoction group (28.35 g·kg-1), cyclical therapy group (11.97/28.35 g·kg-1), and aspirin group (8 × 10-3 mg·kg-1). After 12 days of continuous administration by gavage (equivalent to three estrous cycles), female and male rats were co-housed. On the fifth day of pregnancy, the number of blastocyst implantation in each group was counted. Hematoxylin-eosin (HE) staining was used to observe the pathological morphology of rat endometrial tissue. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of estradiol (E2) and progesterone (P) in rat serum. Western blot was used to detect the protein expression of vascular endothelial growth factor (VEGF), progesterone receptor (PR), estrogen receptor (ER), androgen receptor (AR), and integrin(ITG) αvβ3 in rat endometrial blood vessels. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of miR-140-5 P, VEGF, vascular endothelial growth factor receptor 2 (VEGFR2), PR, ER, AR, and ITGαvβ3 in rat endometrium. ResultsCompared with normal group, the estrous cycle of the rats in model group continued to be in the estrus interval and the estrous cycle lost regular changes. The endometrium was significantly thinner, the number of uterine glands and blood vessels were significantly reduced (P<0.01), and the pregnancy rate was significantly reduced. Compared with the model group, each drug group restored the regular estrous cycle to varying degrees, and the endometrial thickness and the number of blood vessels were significantly improved (P<0.01). The pregnancy rate of each drug group increased, and the effect of the cycle therapy group could reach the normal level. The results of molecular biology experiments showed that compared with the normal group, the levels of serum E2 and P in the model group were significantly decreased (P<0.01), the expression of VEGF, ER, PR and ITGαvβ3 protein was significantly decreased (P<0.05,P<0.01), the expression of AR protein was significantly increased (P<0.01), the expression of miR-140-5P and AR mRNA was significantly increased (P<0.01), and the expression of VEGF, VEGFR2, ER, PR and ITGαvβ3 mRNA was significantly decreased (P<0.01). Compared with model group, the serum E2 level in the Xiaoyaosan group was significantly increased (P<0.01).The levels of E2 and P in serum of rats in Sanzi Yangmo decoction group, cycle therapy group and aspirin group were significantly increased (P<0.01). The expression of AR protein in each drug group was significantly decreased (P<0.01). The expression of VEGF and ITGαvβ3 protein in Xiaoyaosan group was significantly increased (P<0.01). The expression of VEGF, ER and PR protein in Sanzi Yangmo decoction group was increased to varying degrees (P<0.05,P<0.01). The expression of VEGF, PR, ER and ITGαvβ3 protein in the cycle therapy group and the aspirin group increased to varying degrees (P<0.05,P<0.01). The expression of miR-140-5P and AR mRNA in each drug group was significantly decreased (P<0.01). The expression of VEGF, VEGFR2, ER, PR and ITGαvβ3 mRNA in each drug group increased to varying degrees (P<0.05,P<0.01). Compared with Xiaoyaosan group and Sanzi Yangmo decoction group, the expression of miR-140-5P, VEGFR2, ER, PR, AR and ITGαvβ3 mRNA in the cycle therapy group were significantly different (P<0.05,P<0.01). ConclusionThe kidney-tonifying and liver-regulating cyclical therapy may reduce the activity of miR-140-5P, target the upregulation of VEGF expression, mediate angiogenesis, and promote endometrial angiogenesis, thereby playing a synergistic role in improving endometrial receptivity in PCOS-induced infertility. Its efficacy in increasing pregnancy rates surpasses that of Xiaoyaosan or Sanzi Yangmo decoction used alone.

Qingfeitang, specialized in resolving phlegm to stop cough and producing fluid to moisten dryness, is a classic prescription inherited and developed by physicians of successive generations and has been included in the Catalogue of Ancient Classic Prescriptions (First Batch) published by the National Administration of Traditional Chinese Medicine (TCM) in 2018. Relevant ancient books data and modern literature were collected by bibliometrics to analyze the historic origin, formula composition, herb origin, preparation methods, processing methods, clinical effect, and indications of Qingfeitang. The key information of Qingfeitang was summarized to provide reference for the clinical application of the decoction. In this study, a total of 43 pieces of effective data on relevant ancient literature, including 35 ancient TCM books, were collected based on a systematic collation of relevant historic and modern literature. Results showed that "Qingfeitang" was originated from the "Renshen Qingfeitang" recorded in the Taiping Holy Prescriptions for Universal Relief from the Qing dynasty. The name of "Qinfeitang" was first recorded in the Yeshi Luyanfang written by YE Dalian in the Song dynasty. We suggested the modern dosage and usage of Qingfeitang as follows: "Scutellariae Radix of 5.60 g, Platycodon grandiflora, Poria, Tangerine, Fritillaria, and Cortex Mori of 3.73 g respectively, Angelicae Sinensis Radix, Asparagi Radix, Gardeniae Fructus, Armeniacae Semen Amarum, and Ophiopogonis Radix of 2.61 g respectively, Schisandra of 1 g, and Glycyrrhizae Radix et Rhizoma of 1.12 g, and they were taken 3 times daily. The above formula is recommended to be decocted with 400 mL of water, with 3.37 g ginger and 6 g jujubae fructus, to 320 mL, and taken after a meal, three times per day". Qingfeitang has the effect of resolving phlegm to stop cough and producing fluid to moisten dryness, specialized in treating cough, asthma, rash, and other symptoms in ancient times. Modern applications are mainly focused on the respiratory system, used for treating diseases such as bronchopneumonia and cough. The above research results provide a reference basis for the later development and research of Qingfeitang.

BACKGROUND:
Chronic kidney disease (CKD)-associated anemia (CKD-anemia) is associated with poor survival, and hemoglobin targets are often not achieved with current therapies. Phase 3 trials have demonstrated the treatment efficacy of roxadustat for CKD-anemia. This phase 4 study aims to evaluate the long-term (52-week) safety and effectiveness of roxadustat in a broad real-world patient population with CKD-anemia with and without dialysis in China.
METHODS:
This Phase 4 multicenter, open-label, prospective study, conducted from 24 November 2020 to 11 November 2022, evaluated the long-term safety and effectiveness of roxadustat for CKD-anemia in China. Patients aged ≥18 years with CKD-anemia with or without dialysis were included. The initial oral dose was 70-120 mg (weight-based followed by dose adjustment) over 52 weeks. The primary endpoint was safety based on adverse events (AEs). The secondary endpoints were hemoglobin changes from baseline and the proportion of patients who achieved mean hemoglobin ≥100 g/L. Effectiveness evaluable populations 1 (EE1) and EE2 included roxadustat-naïve and previously roxadustat-treated patients, respectively. The safety analysis set (SAF) included all patients who received ≥1 occasion.
RESULTS:
The EE1, EE2, and SAF populations included 1804, 193, and 2021 patients, respectively. In the SAF, the mean age was 50 ± 14 years, and 1087 patients (53.8%) were male. Mean baseline hemoglobin was 96.9 ± 14.0 g/L in EE1 and 100.3 ± 12.9 g/L in EE2. In EE1, the mean (95% confidence interval) hemoglobin changes from baseline over weeks 24-36 and 36-52 were 14.2 (13.5-14.9) g/L and 14.3 (13.5-15.0) g/L, respectively. Over weeks 24-36 and 36-52, 83.3% and 86.1% of patients in EE1 and 82.7% and 84.7% in EE2 achieved mean hemoglobin ≥100 g/L, respectively. In the SAF, 1643 (81.3%) patients experienced treatment-emergent AEs (TEAEs). Overall, 219 (10.8%) patients experienced drug-related TEAEs. Thirty-eight (1.9%) patients died of TEAEs (unrelated to the study drug). Vascular access thrombosis was uncommon.
CONCLUSIONS:
Roxadustat (52 weeks) increased hemoglobin and maintained the treatment target in Chinese patients with CKD-anemia with acceptable safety, supporting its use in real-world settings.

Objective:To explore the factors influencing adherence to voice therapy among patients with voice disorders in China. Methods:Patients with voice disorders who visited the Voice Therapy Center at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, from February to May 2022 were enrolled in the study. Adherence was assessed using the URICA-Voice scale, while influencing factors were assessed through the Voice Handicap Index(VHI) scale and a general information questionnaire. Correlation analysis was conducted using univariate and multivariate logistic regression analysis. Results:A total of 247 patients were included in the study, comprising 57 males(23.08%) and 190 females(76.92%). The results revealed that: ①Female patients demonstrated higher likelihood of being in the contemplation stage(OR=0.22) compared to males. ②Patients with a monthly family income per capita>6 000 yuan were more likely to be in the contemplation stage than those with<3 000 yuan with an OR = 13.94. ③High vocal-demand occupations increased contemplation stage probability(OR=7.70) compared to moderate-demand occupations. ④Residence within 30-minute commute predicted action/maintenance stages(OR=7.14) versus≥60-minute commute. ⑤Patients whose occupations had high voice demands were more likely to be in the action and maintenance stages than those with average voice demands, with an OR of 16.20. Conclusion:Gender, monthly family income per capita, occupational voice demands, and distance to the hospital significantly impact the URICA-Voice compliance stages of patients. Patients who are female, have higher family income, have occupations with high voice demands, and live closer to the hospital exhibit higher compliance with voice training.

AIM:To investigate the effect of Biejiajian pill(BJJP)in reducing carbon tetrachloride(CCl4)-in-duced liver fibrosis in rats and to explore the underlying mechanism of the TLR4-NF-κB signaling pathway.METHODS:A total of 40 male Wistar rats were randomly assigned to 4 groups:control group,model group,low-dose BJJP group,and high-dose BJJP groups,with 10 rats per group.The rat model of liver fibrosis was established by intraperitoneal injection of CCl4,and two doses of BJJP(2.2 g/kg and 0.55 g/kg)were administered simultaneously.After 8 weeks of modeling and BJJP administration,the enzyme-linked immunosorbent assay(ELISA)was used to measure liver injury indicators,including alanine aminotransferase(ALT)and aspartate aminotransferase(AST).Masson trichrome staining and Sirius red staining were performed to assess the fibrin deposition in liver tissue.Immunohistochemistry and Western blot analysis were conducted to detect the expression of extracellular matrix produced by hepatic stellate cells(HSCs).The expression of fibrosis-related proteins was examined using morphological assessment and Western blot.Finally,Western blot analysis was performed to detect the expression of proteins related to the Toll-like receptor 4(TLR4)/myeioid differentiation factor 88(MyD88)/NF-κB signaling pathway.RESULTS:The ELISA results indicated that BJJP treatment significantly re-duced ALT and AST levels in the serum of rats with liver fibrosis(P<0.01).Hematoxylin-eosin staining confirmed the protective effect of BJJP on liver tissue.Morphological analysis using Masson trichrome staining,Sirius Red staining,and alpha smooth muscle actin(α-SMA)immunohistochemical staining demonstrated that BJJP effectively reduced fibrin depo-sition in CCl4-induced rat liver fibrosis.Furthermore,the decreased expression of other markers associated with hepatic stellate cell activation,including fibronectin,collagen type Ⅰ,and α-SMA(P<0.01).Additionally,BJJP treatment sig-nificantly inhibited the activation of the TLR4/MyD88/NF-κB signaling pathway induced by CCl4(P<0.05).CONCLU-SION:BJJP alleviates CCl4-induced liver injury and fibrosis in rats.This effect may be attributed to its inhibition of the TLR4-NF-κB signaling pathway,which subsequently suppressed the HSCs activation.
