ObjectiveTo investigate the effects of Yueju Wan on the 5-hydroxytryptamine （5-HT） signaling pathway in rats with functional dyspepsia （FD） and to explore its therapeutic mechanism in the treatment of FD. MethodsSixty Sprague-Dawley （SD） rats were randomly divided into a normal group， model group， mosapride group （1.575 mg·kg^-1）， and Yueju Wan low-， medium-， and high-dose groups （0.735， 1.47， and 2.94 g·kg^-1， respectively）. The FD rat model was established using GUO's tail-clamping stimulation combined with irregular feeding. After 14 days of modeling， rats were administered the corresponding drugs by gavage for 28 days. After treatment， gastric emptying rate and small intestinal propulsion rate were measured. Serum levels of 5-HT， tryptophan hydroxylase （TPH）， and substance P （SP） were detected by enzyme-linked immunosorbent assay （ELISA）， and acetylcholine （ACh） levels were determined by chemical methods. Histopathological changes in the gastric antrum were observed using hematoxylin-eosin （HE） staining. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to assess the mRNA and protein expression levels of 5-hydroxytryptamine 4 receptor （5-HT4R）， SP， and acetylcholinesterase （AChE） in colon tissue， as well as 5-hydroxytryptamine 3 receptor （5-HT3R）， SP， and AChE in hypothalamic tissue. Immunohistochemistry （IHC） was used to examine the expression of 5-HT and 5-HT4R in the colon and 5-HT and 5-HT3R in the hypothalamus. ResultsCompared with the normal group， the gastric emptying rate and small intestinal propulsion rate in the model group were significantly decreased （P<0.01）. Serum levels of 5-HT， SP， ACh， and TPH were significantly reduced （P<0.01）. Histopathological examination revealed irregular arrangement of glands in the gastric antrum， slight mucosal atrophy， and mild inflammatory cell infiltration. The mRNA and protein expression levels of 5-HT4R， SP， and AChE in colon tissue， as well as 5-HT3R， SP， and AChE in hypothalamic tissue， were significantly decreased （P<0.01）， and 5-HT protein expression in both the colon and hypothalamus was also significantly reduced （P<0.01）. Compared with the model group， all Yueju Wan groups showed significantly increased gastric emptying rate and small intestinal propulsion rate （P<0.01）. The glands in the gastric antrum were more regularly arranged， with no inflammatory cell infiltration observed. Serum levels of 5-HT， SP， ACh， and TPH were significantly increased （P<0.01）. The mRNA and protein expression levels of 5-HT4R， SP， and AChE in colon tissue and 5-HT3R， SP， and AChE in hypothalamic tissue were significantly upregulated （P<0.05， P<0.01）， and 5-HT protein expression in both the colon and hypothalamus was significantly increased （P<0.01）. ConclusionYueju Wan has preventive and therapeutic effects on FD， and its mechanism may be related to regulation of the 5-HT signaling pathway， promotion of brain-gut peptide secretion， and enhancement of gastric motility.

ObjectiveTo investigate the characteristics and potential mechanisms of Luotong Xianrong Yin （LTXRY） in improving lung injury in rats with idiopathic pulmonary fibrosis （IPF） by regulating glycolysis. MethodsForty specific pathogen-free （SPF） Sprague-Dawley （SD） rats were randomly divided into a sham-operated group （10 mL·kg^-1）， model group （10 mL·kg^-1）， LTXRY group （15.18 g·kg^-1）， and nintedanib group （0.1 g·kg^-1）， with 10 rats in each group. The IPF rat model was established by intratracheal instillation of bleomycin. After 28 days of gavage intervention， pulmonary function was assessed. Lung pathological changes were observed by hematoxylin-eosin （HE） and Masson staining. Enzyme-linked immunosorbent assay （ELISA） was used to determine the levels of inflammatory factors， including tumor necrosis factor-α （TNF-α）， interleukin （IL）-1β， and IL-6， in lung tissue. Chemiluminescence assays were employed to detect lactate content and lactate dehydrogenase activity in lung tissue. Western blot was used to measure the protein expression of transforming growth factor-β₁ （TGF-β₁）， CollagenⅠ and CollagenⅢ to evaluate collagen deposition， as well as hexokinase 2 （HK2）， pyruvate kinase M2 （PKM2）， and 6-phosphofructo-2-kinase/fructose-2，6-bisphosphatase 3 （PFKFB3） to assess glycolysis levels. Network pharmacology was applied to analyze the potential targets and signaling pathways of LTXRY in IPF， and molecular docking was conducted to evaluate the binding energy between active components and potential targets. Western blot was further used to detect the expression of target- and pathway-related proteins. ResultsCompared with the sham-operated group， rats in the model group showed significantly increased main airway resistance （Rn） and respiratory system resistance （Rrs）， and significantly decreased respiratory system compliance （Crs）. Inflammatory infiltration and collagen deposition were observed in lung tissue， with significantly increased levels of TNF-α， IL-1β， and IL-6， as well as elevated protein expression of TGF-β₁， CollagenⅠ and CollagenⅢ. Lactate content， lactate dehydrogenase activity， and the protein expression of HK2， PKM2， and PFKFB3 in lung tissue were significantly increased. Network pharmacology analysis indicated that signal transducer and activator of transcription 3 （STAT3） was a key target of LTXRY in IPF， and hypoxia-inducible factor-1 （HIF-1） was a critical signaling pathway. The expression levels of phosphorylated STAT3 （p-STAT3） and HIF-1α in lung tissue were significantly higher than those in the sham-operated group. Compared with the model group， rats in the LTXRY group showed significantly decreased Rn and Rrs and significantly increased Crs. Lung inflammatory infiltration and collagen deposition were markedly alleviated， with significantly reduced levels of TNF-α， IL-1β， and IL-6， and decreased protein expression of TGF-β₁， CollagenⅠ and CollagenⅢ. Lactate content， lactate dehydrogenase activity， and the protein expression of HK2， PKM2， and PFKFB3 were significantly decreased， accompanied by markedly reduced expression of p-STAT3 and HIF-1α. ConclusionLTXRY alleviates lung tissue injury in IPF rats by regulating glycolysis mediated by the STAT3/HIF-1α signaling pathway.

Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it.

OBJECTIVE To explore the efficacy and safe ty of Tripterygium wilfordii polyglycoside combined with finerenone in the treatment of diabetic nephropathy （DN）. METHODS This study selected 104 DN patients admitted to the Nephrology Department of Handan Central Hospital from January 2023 to May 2024 as the subjects and randomly assigned them into the control group （52 cases） and the combination group （52 cases）. All patients received basic treatment such as lipid-lowering and blood glucose control. On this basis， patients in the control group received finerenone， while those in the combination group received a combination therapy of T. wilfordii polyglycoside and finerenone. Both groups underwent treatment for a duration of three months. The two groups were compared in terms of clinical efficacy， renal function indicators [24-hour urine protein excretion （24 h UPE）， urinary albumin-to-creatinine ratio （UACR）， urinary albumin excretion rate （UAER） ] ， inflammatory factors [high mobility group box 1 protein （HMGB1）， interleukin-6 （IL-6）， nuclear factor-κB （NF-κB）， high-sensitivity C reactive protein （hs-CRP） ] ， and oxidative stress indicators [total antioxidant capacity （T-AOC）， superoxide dismutase （SOD）， advanced oxidation protein products （AOPP）， malondialdehyde （MDA） ] before and after treatment. Additionally， the occurrence of adverse drug reactions was recorded. RESULTS In terms of efficacy， the total effective rate of patients in the combination group was higher than that of the control group （ P ＜0.05）. After treatment， the levels of 24-h UPE， UACR， UAER， HMGB1， IL-6， NF-κB， hs-CRP， AOPP and MDA in the two groups were significantly lower than those in the same group before treatment； the levels of T-AOC and SOD in the two groups were significantly higher than those in the same group before treatment， with the combination group showing superior changes in the above indicators compared to the control group at the corresponding time point （ P ＜0.05）. In terms of safety， there was no statistical significance in the total incidence of adverse drug reactions between the two groups （ P ＞0.05）. CONCLUSIONS Compared to finerenone monotherapy， the combination therapy of T. wilfordii polyglycoside and finerenone demonstrates significant efficacy in treating DN. It effectively reduces proteinuria levels， alleviates inflammatory reaction， mitigates oxidative stress， and does not increase the risk of adverse reactions.

OBJECTIVE To develope a predictive model for medication deviation risks during the hospital-to-home transition period in coronary heart disease （CHD） patients with initial treatment， aiming to assist medical staff in rapidly identifying high-risk groups for medication deviation. METHODS A total of 462 CHD patients with initial treatment from the Affiliated Hospital of North China University of Science and Technology （hereinafter referred to as “our hospital”） between January and July 2024 were enrolled. The patients were randomly divided into a modeling group and an internal validation group. The modeling group was further categorized into a medication deviation group and a non-medication deviation group based on whether medication deviations occurred. Similarly， 57 CHD patients with initial treatment from the cardiology department of our hospital between June and September 2025 were collected as an external validation group. Univariate analysis was used to screen predictive factors， followed by multivariate Logistic regression to construct the predictive model. Internal validation methods were employed to evaluate model performance， while external validation methods were used to test the model’s generalizability. RESULTS The 462 patients were divided into a modeling group （319 cases） and an internal validation group （143 cases）. In the modeling group， the medication deviation group （192 cases， 60.19%） and the non-medication deviation group （127 cases， 39.81%） were identified. Multivariate Logistic regression analysis revealed that age， medication type， medication adherence， and self-efficacy in rational medication use were predictive factors for medication deviations in CHD patients with initial treatment （ P ＜0.05）. The predictive model equation was logit P ＝ln[ P /（1－ P ） ] ＝1.321+1.732×age+4.091×medication type －4.360×medication adherence －3.081×self-efficacy in rational medication use. The model demonstrated good discrimination， with a Hosmer-Lemeshow goodness-of-fit test P -value of 0.439， an area under the receiver operating characteristic curve （AUC） of 0.870， sensitivity of 0.970， and specificity of 0.607. A risk nomogram with a total score of 350 points and a cutoff value of 110 points was plotted. The internal validation group showed an AUC o f 0.787 and a prediction accuracy of 77.6%， while the external validation group exhibited an AUC of 0.802 and a prediction accuracy of 73.7%. CONCLUSIONS This study successfully developed a predictive model for medication deviation risks during the hospital-to-home transition period in CHD patients with initial treatment. The model demonstrates excellent discrimination and predictive accuracy， effectively identifying high-risk populations for medication deviations. Age （＞70 years）， number of drug types≥5， poor medication adherence， and poor self-efficacy in rational medication use are independent risk factors for medication deviations.

OBJECTIVE To evaluate the cost-effectiveness of amivantamab combined with lazertinib （hereinafter referred to as “AL”） regimen as first-line treatment for EGFR -mutated advanced non-small cell lung cancer （NSCLC） from the perspective of China’s healthcare system. METHODS A partitioned survival model was established based on updated data from the MARIPOSA study， with a 10-year time horizon and 28-day cycles. The primary outcome index was quality adjusted life year （QALY）， and the willingness-to-pay （WTP） threshold was set at three times China’s per capita GDP in 2024 （287 247 yuan/QALY）. Cost-utility analysis was used to calculate the incremental cost-effectiveness ratio （ICER） of AL regimen versus osimertinib monotherapy regimen as first-line treatment for EGFR -mutated advanced NSCLC. One-way and probabilistic sensitivity analyses were performed to test model robustness. Scena rio analyses were conducted to explore the impact of utility values for different health states on the outcomes and determine the required price reductions of amivantamab and lazertinib to achieve cost-effectiveness. RESULTS Compared with the osimertinib monotherapy regimen， the ICER for the AL regimen as first-line treatment for advanced EGFR -mutated NSCLC was 2 062 096.15 yuan/QALY， significantly exceeding the WTP threshold established in this study. One-way sensitivity analysis revealed that the utility value of progression-free survival state and the price of amivantamab were the primary factors influencing the ICER. Probabilistic sensitivity analysis revealed that the AL regimen only became cost-effective when the WTP threshold was set at 2 050 000 yuan/QALY. Scenario analysis indicated that altering the utility value still rendered the AL regimen non-cost-effective. When amivantamab （350 mg） prices decreased by 80%， 85%， and 90% respectively， lazertinib （80 mg） prices would need to decrease by 95.97%， 40.63%， 5.29%， respectively. This would enable the AL regimen’s ICER to consistently fall within the WTP threshold established in this study. CONCLUSIONS At the WTP threshold established in this study， the AL regimen does not demonstrate cost-effectiveness for first-line treatment of advanced EGFR -mutated NSCLC compared to the osimertinib monotherapy regimen. Significant price reductions for both drugs would be required to alleviate the financial burden on patients.

Objective To evaluate the effect of LifePort combined with polymyxin B in preventing donor-derived infections caused by preservation solution contamination. Methods Clinical data of 110 kidney transplant recipients were retrospectively analyzed. According to the decontamination status of preservation solution, the recipients were divided into the decontamination group (n=62) and the non-decontamination group (n=48). The general data of the two groups were compared, and the preventive effect of polymyxin B on possible donor-derived infections (p-DDI) was analyzed, especially infections associated with multidrug-resistant Gram-negative bacteria (MDR GNB). Results There were no statistically significant differences in baseline data (gender, age, preservation solution contamination status, etc.) between the decontamination group and the non-decontamination group (all P > 0.05). The overall contamination rate of preservation solution was 80.0%, and 68 contaminated samples were with single microorganism and 20 with multiple microorganisms. Coagulase-negative staphylococci, Enterococcus and Klebsiella pneumoniae were the most common microorganisms in the positive samples. Fifteen cases of preservation solution were contaminated by MDR GNB, including 10 cases in the non-decontamination group and 5 cases in the decontamination group, with no statistically significant difference between the two groups (P = 0.053). Postoperative infection-related events occurred in 69 recipients, including 39 cases in the non-decontamination group and 30 cases in the decontamination group, with the incidence rate in the non-decontamination group significantly higher than that in the decontamination group (P < 0.001). Only 10 cases of infections were identified as p-DDI, all of which were positive for preservation solution culture, including 8 cases in the non-decontamination group and 2 cases in the decontamination group (P < 0.05). There were 5 cases of p-DDI related to MDR GNB in the non-decontamination group, while no such cases occurred in the decontamination group (P < 0.05). No adverse reactions related to polymyxin B were observed, and no recipient death or renal allograft dysfunction occurred in either group. Conclusions Adding polymyxin B to the preservation fluid during hypothermic machine perfusion with LifePort before renal transplantation may reduce p-DDI and its potential adverse consequences.
