Tracheobronchial adenoid cystic carcinoma (TACC) is a low-grade malignant tumor originating from the airway mucosa. Despite its slow progression,it is characterized by high invasiveness,frequent recurrence,and a strong tendency for metastasis. Preclinical studies have shown that vascular-targeted therapy holds significant potential. However,an effective systemic treatment for TACC has not been established yet. This study explored TACC from the perspective of "Feiji" in traditional Chinese medicine (TCM) as the starting point. It deeply investigated the mechanisms of abnormal collaterals and tumor vascular recruitment and further elaborated on the theoretical connection between abnormal collaterals and tumor vascular recruitment. Firstly,collateral hyperactivity led to disordered and erratic pulmonary collaterals. Their abnormal structures were similar to the disorderly and tortuous nature of tumor (pseudo)angiogenesis. This resulted in imbalances in the functions of circulation,perfusion,and reverse injection of the pulmonary collaterals,and then led to unrestrained collateral dysfunction and the accumulation of pathogenic factors. Secondly,the remodeling of the extracellular matrix (ECM) and epithelial-mesenchymal transition (EMT) in TACC were critical processes in vascular co-option (VCO),representing the micro-level manifestation of the displacement of nutrient and defense. During this process,ECM remodeling made TACC cells more likely to hijack normal blood vessels,creating a complex vascular microenvironment conducive to tumor growth. In terms of treatment,this study proposed a TCM strategy of "regulating collaterals to expel pathogenic factors and nourishing collaterals to strengthen the healthy Qi",and listed potential TCM. These were intended to regulate the Qi and blood in the collaterals,repair the functions of abnormal collaterals,and intervene in the vascular recruitment process of TACC. Future research should focus on improving the TCM clinical syndrome characteristics of TACC. Through modern molecular biology techniques,it is necessary to deeply analyze the micro-level pattern of vascular recruitment in TACC. This would enrich the understanding of the profound connection between abnormal collaterals and tumor vascular recruitment,providing empirical evidence for TCM-targeted therapies for vascular recruitment in TACC.

OBJECTIVE To provide technical support for improving recognition rate of adverse drug events (ADEs) related to traditional Chinese medicine (TCM) formula granules and decoction pieces among inpatient patients. METHODS By referencing the global trigger tool (GTT) whitepaper, literature on adverse reactions to TCM, and expert review opinions, ADE trigger items for TCM formula granules and decoction pieces used in the inpatients were established. GTT was applied to analyze ADEs in inpatients who had used TCM formula granules and decoction pieces in our hospital from August 2013 to August 2023, utilizing the Chinese Hospital Pharmacovigilance System. The effectiveness of GTT and the characteristics of these ADEs were analyzed. RESULTS A total of forty-eight triggers were established, including thirty-two laboratory test indexes, thirteen clinical symptoms, and three antidotes. Among the 1 682 patients included, GTT identified 652 potential ADEs, 284 true positive ADEs,with a trigger rate of 38.76% and a positive predictive value of 43.56%. After review by the auditor, 278 cases of ADEs were finally confirmed, with an incidence rate of 16.53%, significantly higher than the number of spontaneously reported ADEs during the same period (0). The 278 cases of ADEs were mostly grade 1 (223 cases), mainly involving hepatobiliary system, gastrointestinal system, blood- lymphatic system, etc;a total of 219 types of TCMs are involved,and the top five suspected TCMs used at a frequency higher than 1% were Poria cocos, Codonopsis pilosula, Atractylodes macrocephala, fried Glycyrrhiza uralensis, and Scutellaria baicalensis. CONCLUSIONS The established GTT can improve the recognition rate of ADEs for hospitalized patients using traditional Chinese medicine formula granules and decoction pieces.

OBJECTIVE To investigate the effects of peiminine B (PEI) on Streptococcus pneumoniae (SP)-induced alveolar epithelial cell injury by regulating the Ras-related C3 botulinum toxin substrate 1 in nucleus accumbens (Rac1)/protein kinase B (Akt)/nuclear factor κB (NF-κB) signaling pathway. METHODS Human alveolar epithelial cells (HPAEpiC) were taken and randomly divided into the Control group, SP group (1×108 cfu/mL SP bacterial solution), low-, medium-, and high-concentration PEI groups (1×108 cfu/mL SP bacterial solution+0.05, 0.10, 0.20 mmol/L PEI), and high-concentration PEI+Akt activator group (P-H+SC79 group, 1×108 cfu/mL SP bacterial solution+0.20 mmol/L PEI+10 μmol/L SC79). Except for the Control group, the other groups of cells were treated with SP bacterial solution and/or corresponding drug solution. After 24 h of treatment, the levels of inflammatory factors (interleukin-6, -18, -1β) in the supernatant solution, the contents of oxidative stress indexes [lactate dehydrogenase (LDH), reactive oxygen species (ROS) and superoxide dismutase (SOD)], apoptosis rate, as well as the expressions of proliferation/apoptosis-related proteins [cyclin-dependent kinase 1 (CDK1), B cell lymphoma-2 related X protein (Bax)] and pathway-related proteins (Rac1, Akt, phosphorylated Akt, NF-κB and phosphorylated NF-κB) were detected in each group. RESULTS Compared with the Control group, the levels of inflammatory factors in supernatant solution, LDH and ROS contents, apoptosis rate, the protein expressions of Bax and Rac1 and the phosphorylation levels of Akt and NF-κB in the SP group were significantly increased or up-regulated, while SOD content and the protein expression of CDK1 were significantly decreased or down-regulated (P<0.05). Compared with the SP group, the above indexes in PEI groups were significantly improved in a concentration-dependent manner (P<0.05). SC79 could significantly reverse the improvement effect of the high concentration of PEI (P<0.05). CONCLUSIONS PEI can alleviate SP-induced inflammation and oxidative stress damage of alveolar epithelial cells and inhibit apoptosis, which may be achieved by inhibiting Rac1/Akt/NF-κB signaling pathway.

To investigate the therapeutic effect and related mechanisms of hordenine on ovalbumin (OVA)-induced allergic rhinitis (AR) in rats, HE and AB-PAS staining were used to detect the improvement of pathological damage to the nasal mucosa induced by hordenine. ELISA was employed to detect the effect of hordenine on OVA-sIgE in serum and IL-4 in the nasal mucosa supernatant of rats. IHC and Western blot experiments were undertaken to examine the effect of hordenine on Th1/Th2 cell balance. Bioinformatics analysis was performed to predict pathways, which were verified by in vivo and in vitro experiments. The experimental results showed that hordenine could alleviate the behavioral manifestations of OVA-induced AR rats, alleviate nasal mucosal pathological damage caused by AR, and reduce the secretion of OVA-sIgE and IL-4. In addition, hordenine could regulate the Th1/Th2 balance. Bioinformatics analysis results showed that the potential pathway of action of hordenine on AR was the phosphoinositide 3 kinase (PI3K)/protein kinase B (Akt) signaling pathway. The in vivo experimental results showed that the expression of PI3K and p-Akt proteins in the nasal mucosa of the model group rats was significantly increased (P < 0.01), and that the protein expression level was significantly decreased after the administration of hordenine, which was also confirmed by an in vitro experiment. This study suggests that hordenine may regulate Th1/Th2 cell balance through the PI3K/Akt signaling pathway, thereby exerting an alleviating effect on OVA-induced AR.

ObjectiveTo develop a classification model based on complete blood count (CBC) parameters combined with clinical factors to predict severe respiratory infections caused by Human adenovirus (HAdV) in pediatric patients. MethodsFrom September 2023 to September 2024, the CBC parameters and related clinical data from pediatric patients diagnosed with HAdV infection were collected. Principal component analysis and random forest models were used to identify potential predictors of severe cases. ResultsA total of 668 pediatric patients were included, with 564 cases assigned to the training cohort and 104 cases to the validation cohort. Severe cases were defined as pneumonia and/or fever lasting ≥5 days (pneumonia or prolonged fever, PorPF). Principal component analysis and feature importance analysis (Mean Decrease Gini value) identified the monocytosis ratio (PMono), red blood cell count (RBC), and platelet count (PLT) as the most critical CBC parameters. Logistic regression analysis revealed that oxygen therapy (OR = 4.367, 95% CI: 1.568–12.161) and increased work of breathing (OR = 3.904, 95% CI: 2.146–7.101) were relative risk factors for PorPF. Meanwhile, higher PMono (OR = 0.696, 95% CI: 0.640–0.757), RBC (OR = 0.201, 95% CI: 0.124–0.325), and PLT (OR = 0.990, 95% CI: 0.987–0.994) were protective factors. When PMono was used as a predictive marker for PorPF, the area under the receiver operating characteristic curve (AUC) was 0.648 and 0.705, respectively. A random forest model incorporating four risk factors [PMono, RBC, PLT, and hematocrit (HCT)] was constructed to classify PorPF and general cases, achieving AUCs of 0.688 and 0.768, respectively. ConclusionsPMono, RBC, and PLT may serve as characteristic CBC indicators for predicting pneumonia or prolonged fever in children with HAdV infection. A risk factor model built using PMono, RBC, PLT, and HCT offers a relatively simple and accurate approach to predicting severe cases in pediatric HAdV infections.

ObjectiveTo investigate the effect of phytoestrogen biochanin A (BCA) on liver fibrosis induced by CCl4 in female mice with bilateral oophorectomy (ovariectomized) and its mechanism. MethodsA total of 50 ovariectomized Kunming mice were selected and given intraperitoneal injection of CCl4 to establish a model of liver fibrosis, and then according to body weight, they were randomly divided into model group, positive control group, and low-, middle-, and high-dose BCA groups, with 10 mice in each group. In addition, 10 female mice in the same litter were given resection of a small amount of adipose tissue near both ovaries to establish the sham-operation group. The mice in the positive control group were given estradiol 2 mg/kg by gavage, and those in the low-, middle-, and high-dose BCA groups were given BCA by gavage at a dose of 25, 50, and 100 mg/kg, respectively, once a day for 7 consecutive weeks; the mice in the sham-operation group and the model group were given an equal volume of 0.5% sodium carboxymethyl cellulose solution by gavage. The mice were anesthetized and sacrificed after administration to collect samples. Liver index and uterus index were measured; HE staining and Masson staining were used to observe liver histopathological changes; the biochemical analysis was used to measure the activity of aspartate aminotransferase (AST) and alanine aminotransferase (ALT); ELISA was used to measure the levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in liver tissue, and Western blot was used to measure the relative protein expression levels of collagen Ⅰ, transforming growth factor-beta 1 (TGF-β1), alpha-smooth muscle actin (α-SMA), estrogen receptor beta (ERβ), and p-NF-κBp65/NF-κBp65 in liver tissue. The t-test was used for comparison of continuous data between two groups; a one-way analysis of various was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and further comparison between two groups. ResultsCompared with the sham-operated group, the model group had a significant increase in liver index and a significant reduction in uterus index, as well as significant increases in the activities of serum AST and ALT, the levels of IL-6 and TNF-α in liver tissue, and the protein expression levels of collagen Ⅰ, TGF-β1, α-SMA, and p-NF-κBp65/NF-κBp65 in liver tissue (all P<0.05), with no significant change in the expression of ERβ in liver tissue (P>0.05), and the model group showed significant fibrosis lesions in the liver, such as hepatocyte edema, steatosis, and necrosis with inflammatory cell infiltration and hyperplasia, deposition, and staggered distribution of collagen fibers. Compared with the model group, the low-, middle-, and high-dose BCA groups had significant reductions in liver index, the activities of serum AST and ALT, the levels of IL-6 and TNF-α, and the protein expression levels of collagen Ⅰ, TGF-β1, α-SMA, and p-NF-κBp65/NF-κBp65 in liver tissue (all P<0.05), with no significant change in uterine index (P>0.05), as well as a significant increase in the protein expression level of ERβ in liver tissue (P<0.05) and varying degrees of improvement in liver fibrosis lesions. ConclusionBCA can effectively improve CCL4-induced liver fibrosis in ovariectomized female mice, possibly by upregulating ERβ to inhibit the NF-κB signaling pathway and then alleviating inflammatory response.

Recent studies have identified that metabolic reprogramming in lung adenocarcinoma cells,particularly lactate metabolism disorders,plays a crucial role in tumor development and immune therapy response.The accumulation of lactic acid not only provides energy support for the proliferation of tumor cells but also affects the function of immune cells by changing the tumor microenvironment,thereby promoting immune escape.Immunotherapy,especially the application of immune checkpoint inhibitors,has become an important strategy for treating lung adenocarcinoma.However,lactate metabolism disorders might affect the efficacy of immunotherapy,leading to resistance in some patients.Therefore,a thorough understanding of the mechanisms of lactic acid metabolism in lung adenocarcinoma and its impact on the response to immu-notherapy is essential for developing new therapeutic strategies and improving the efficacy of immunoth-erapy.This review summarizes the role of lactate metabolism disorders in the development and immun-otherapy of lung adenocarcinoma,discusses the potential role of lactic acid metabolism-related genes and pathways in lung adenocarcinoma,and explores the progress in therapeutic strategies targeting lactic acid metabolism regulation.This work aims to provide new insights for the treatment of lung adenocarcinoma.

Objective:To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors.Methods:This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects′ music listening was investigated using SPSS 25.0 statistical software.Results:All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors ( P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors ( P value>0.05). Conclusions:Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.
