This paper summarizes professor TU Jinwen's clinical experience in treating cancer-related insomnia (CRI) based on different qi and fire. It is believed that the pathogenesis of CRI can be divided into three stages. At the initial stage, qi movement is constrained, while the strong fire begins to stir, and the sovereign fire is unsettled, when qi is abundant, but the fire is not excessive. For this, Sanhua Jieyu Anshen Decoction (三花解郁安神汤) is suggested, which can move qi and vent constraint, clear and diffuse strong fire, calm the heart and spirit. At the progressive stage, strong fire becomes intense and burning, and qi transformation weakens, with toxin fire harassing the spirit. This is the stage where both qi and fire are excessive, for which Huanglian Jiedu Anshen Decoction (黄连解毒安神汤) can be used to clear and dissipate strong fire, drain fire and resolve toxin, clear heart and calm spirit. At the terminal stage, strong fire subsides, and consumption of qi damages healthy qi, with failure of nourishment of heart spirit, when both qi and fire deplete. Correspondingly, Erren Yangxin Anshen Decoction (二仁养心安神汤) is used to boost qi and nourish yin, restore interaction between the heart and the kidney, nourish the heart and calm spirit.

ObjectiveTo explore the efficacy and mechanism of Euphorbia humifusa on acute kidney injury (AKI) based on network pharmacology, molecular docking and experimental verification. MethodsThe active components and targets of E. humifusa were retrieved from TCMSP and SwissTargetPrediction database, and the AKI targets were screened by GeneCards and Online Mendelian Inheritance in Man(OMIM) databases. The drug targets and disease targets were intersected to construct a protein-protein interaction network, and the intersection targets were subjected to gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. Discover Studio software was used to verify the molecular docking of key components and core targets. Gentamicin (GM) was used to induce AKI rat model. Control group, model group, verapamil (16 mg·kg-1) group, E. humifusa extract (18, 54, 162 mg·kg-1·d-1) group and E. humifusa 70% ethanol extract (423 mg·kg-1) group were continuously administered for 14 days. Urine volume was detected 24 h after modeling and administration. Serum creatinine (SCr), Blood urea nitrogen (BUN), 24-hour urine protein (24 hUTP) and uric acid (UA) content; the contents of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), carbon monoxide synthase (NOS) and lactate dehydrogenase (LDH) in kidney were measured. The levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α in serum were detected by enzyme linked immunosorbent assay(ELISA) kit. The pathological changes of renal tissue were detected by hematoxylin-eosin (HE) and Masson staining. Western blot was used to detect the expression of PI3K/protein kinase B(Akt)/NF-κB signaling pathway-related proteins. ResultsIn this study, 13 active components such as kaempferol, luteolin, apigenin, gallic acid and quercetin were screened and identified from E. humifusa. Through bioinformatics analysis, these components and AKI have a total of 289 targets, of which 62 are core targets, including Akt1, TNF, tumor protein p53(TP53) and IL-1β. These targets are mainly involved in the regulation of biological processes such as NF-κB signaling pathway, HIF-1 signaling pathway, TNF signaling pathway, PI3K/Akt signaling pathway and mitogen-activated protein kinase(MAPK) signaling pathway. In animal experiments, we successfully constructed a GM-induced AKI model in rats. Compared with the model group, E. humifusa extract could significantly reduce the levels of 24 hUTP, BUN and SCr in rats (P<0.01), indicating its improvement effect on renal function. In addition, the extract of E. humifusa also significantly reduced LDH activity and MDA content in rat kidney tissue (P<0.05, P<0.01), and significantly increased SOD, NOS activity and GSH content (P<0.05), indicating that the extract of E. humifusa has the potential of anti-oxidation and protection of renal function. Further analysis of inflammatory factors showed that the levels of IL-6 and TNF-α in serum of rats treated with E. humifusa extract were significantly decreased (P<0.01), indicating that E. humifusa extract had anti-inflammatory effects. In addition, the extract of E. humifusa can also regulate the protein expression of PI3K/Akt/NF-κB signaling pathway, which further confirmed its mechanism of reducing GM-induced AKI. ConclusionThe extract of E. humifusa has a significant therapeutic effect on acute kidney injury through its multi-component and multi-target mechanism. Its effect is reflected in improving renal function, anti-oxidation, anti-inflammation and regulating immune response. These findings provide a scientific basis for the application of E. humifusa in the treatment of acute kidney injury, and point out the direction for future drug development and clinical research.

Objective To explore the effect of sex on the incidence of immune-related cutaneous adverse event (ircAE) during immunotherapy for gastric cancer, and to further analyze the correlation between sex, ircAE and prognosis. Methods A retrospective analysis was conducted on patients with advanced gastric cancer who received immune checkpoint inhibitors at the Department of Oncology, Nanjing Drum Tower Hospital, The Affiliated Hospital of Medical School, Nanjing University, from February 1, 2022, to December 31, 2024. Clinicopathological characteristics, occurrence of ircAE, and survival data were collected. The incidence of ircAE was compared between male and female patients. Kaplan-Meier method was used to plot survival curves, and univariate Cox regression analysis was performed to assess prognostic factors. Results A total of 116 patients with advanced gastric cancer were enrolled, including 76 males (65.5%) and 40 females (34.5%). The overall incidence of ircAE was 23.28%, with a higher incidence in male patients than in female patients (28.95% vs 12.50%, P=0.046). Kaplan-Meier survival analysis on 86 patients with complete follow-up data indicated that patients with ircAE had longer overall survival (OS) than those without ircAE (P=0.045). Univariate Cox regression analysis showed that male (HR=0.43, 95%CI 0.22–0.83, P=0.012) was associated with prolonged OS. Conclusions In gastric cancer immunotherapy, male patients are more likely to develop ircAE and have longer OS than female patients, and the occurrence of ircAE may be related to prolonged OS.

Objective The study aimed to elucidate the population composition and seasonal distribution characteristics of mosquitoes in Laoshan District, Qingdao City, providing a scientific basis for the prevention and control of mosquito-borne infectious diseases. Methods Mosquito surveillance was conducted in Laoshan District in Qingdao City using light traps from April to November 2020-2022. Dominant mosquito species were identified using the Berger-Parker dominance index(I)and mosquito density was compared using the Kruskal-Wallis H test. The seasonal distribution characteristics of adult mosquitoes were analyzed using concentration and circular distribution method. Spearman rank correlation analysis was used to study the relationship between mosquito populations and meteorological factors with mean monthly temperature, mean monthly relative humidity, and mean monthly rainfall. Results The mean mosquito density for the trapping period was 9.771 females/(trap·night)in 2020,9.771 in 2021, and 9.427 in 2022. There was no statistically significant difference in mosquito density between different years(H = 0.095, P = 0.954). In total, 2 781 adult female mosquitoes comprising five species from four genera were captured over three years. Culex pipiens(I = 0.654), Aedes albopictus(I = 0.202), and Aedes aegypti(I = 0.118)were identified as dominant species. Seasonal fluctuations in the adult mosquitoes were unimodal, and primarily concentrated from June to September. The peak period of adult mosquito varied between years with statistical significance. (F = 3.838, P < 0.05). Mosquito density was highly correlated with mean monthly temperature, mean monthly relative humidity and mean monthly precipitation(P< 0.05). Conclusions Cx. pipiens pallens, Ae. albopictus, and Ar. inamoratus are the dominant mosquito species in the Laoshan District of Qingdao City. The activity of adult mosquitoes is seasonal, and primarily concentrated in summer and autumn, during which the risk of mosquito-borne diseases such as dengue fever is increased.

Objective To develop a predictive model of acute hematologic toxicity (HT) based on preradiotherapy CT radiomic features combined with clinical and dosimetric characteristics for patients with cervical cancer undergoing definitive radiotherapy. Methods Data from 82 patients with cervical cancer who received definitive radiotherapy were retrospectively analyzed. The patients were divided into training and test sets at an 8:2 ratio, with grade ≥2 HT as the study endpoint. Clinical characteristics and dosimetric parameters of pelvic regions were collected, and 1 046 radiomic features were extracted from the overall pelvic structure using PyRadiomics. Radiomic features were processed using Z-score normalization, Spearman correlation analysis (>0.9), and LASSO regression for feature selection. A radiomics model was constructed using K-nearest neighbor machine learning with fivefold cross-validation. For 56 clinical and dosimetric features, independent predictors were identified through univariate and multivariate analyses to establish a clinical-dose model. A hybrid model was further constructed by combining the two sets of features. Model performance was evaluated using the area under the receiver operating characteristic curve (AUC), decision curve analysis, and calibration curves. Results Forty patients (48.8%) developed grade ≥2 HT. Univariate and multivariate analyses showed that V20 of the lumbosacral spine was significantly associated with grade ≥2 HT (P<0.05). The AUC values for the radiomics, clinical-dose, and hybrid models were 0.802, 0.750, and 0.861 in the training set, respectively, and 0.703, 0.633, and 0.781 in the test set, respectively. Conclusion Preradiotherapy CT radiomic features combined with dosimetric characteristics can predict the occurrence of acute hematologic toxicity in patients with cervical cancer, potentially facilitating early clinical intervention.

Chinese Journal of Experimental Traditional Medical Formulae 2025;31(2):268-278
This article provides a systematic review of the research progress in the mechanisms related to lung cancer and ferroptosis, ferroptosis-related lung cancer biomarkers and gene mutation targets, and ferroptosis-targeted regulation of Chinese medicine in treating lung cancer in the past five years, providing a feasible and effective basis for the prevention and treatment of lung cancer with Chinese medicine and the development of new drugs. According to the available studies, ferroptosis is widely suppressed in lung cancer, while the specific regulatory mechanisms have not been fully elucidated. The suppression is related to lipid metabolism, iron metabolism, cystine/glutamate antiporter system Xc- (System Xc-)/glutathione (GSH)/glutathione peroxidase 4 (GPX4), ferroptosis suppressor protein 1 (FSP1)/coenzyme Q10 (CoQ10)/nicotinamide adenine dinucleotide phosphate [NAD(P)H], long non-coding RNA (lncRNA), nuclear factor E2-related factor 2 (Nrf2), and p53. In modern times, traditional Chinese medicine is widely used in the comprehensive treatment of lung cancer, and it has gradually become a hot research topic due to its obvious advantages of anti-tumor activity, high efficacy, and low toxicity. Traditional Chinese medicine plays an important role in the treatment of lung cancer. Studies have shown that the active components, extracts, and prescriptions of Chinese medicine can induce ferroptosis in lung cancer cells through targeted regulation of iron metabolism, lipid metabolism, and p53, Nrf2, LncRNA, and GPX4 pathways to inhibit the growth and proliferation of lung cancer, thus exerting anti-tumor effects. Therefore, regulating ferroptosis is expected to become a new direction for preventing lung cancer. Basic research has shown that Chinese medicine can regulate ferroptosis via multiple targets and pathways in the treatment of lung cancer. At present, Chinese medicine demonstrates great research prospects in regulating ferroptosis to treat lung cancer, which, howeve, still faces challenges to achieve clinical transformation.

Objective To construct an aptamer-functionalized carboxylated graphene oxide(CGO)fluo-rescent sensor to achieve highly sensitive and specific detection of ketamine(KET)and its metabolite norketamine(NK)using an aptamer capable of simultaneously recognizing KET and NK.Methods A specific aptamer for simultaneous recognition of KET and NK was screened using graphene oxide-sys-tematic evolution of ligand by exponential enrichment(GO-SELEX)and molecular docking tech-niques.The aptamer,labeled with Cy5 fluorescence,was chemically conjugated to CGO to construct an aptamer-functionalized CGO fluorescent sensor.By optimizing detection conditions,including the mass concentration of CGO,aptamer concentration,reaction temperature,and incubation time,quantita-tive analysis of the target analytes was achieved using the ratio of fluorescence intensity changes be-fore and after target addition.The stability of the sensor in biological matrices was evaluated by moni-toring fluorescence intensity changes over incubation time in blank blood and urine,in comparison with the traditional physical adsorption-based CGO fluorescent sensor.Spiked recovery experiments in blank blood and urine were conducted to compare performance with that of HPLC-MS/MS.Results A specific aptamer A5 was selected and chemically conjugated with CGO to construct the aptamer-functionalized CGO fluorescent sensor.Under optimized conditions,the proposed fluorescent sensor ex-hibited a linear detection range of 1.0-5.0 ng/mL for KET,with a limit of detection(LOD)of 0.86 ng/mL;while for NK,the linear detection range was 1.0-5.0 ng/mL,with an LOD of 0.70 ng/mL.Com-pared with the CGO fluorescent sensor constructed via physical adsorption,this sensor demonstrated greater stability in blood and urine.The spiked recovery rates of KET and NK in blank blood and urine ranged from 81.50%to 110.03%,exhibiting detection performance comparable to that of HPLC-MS/MS.Conclusion The aptamer screening method offers a novel approach for selecting aptamers tar-geting drugs and their metabolites.The constructed aptamer-functionalized CGO fluorescent sensor pro-vides an efficient and reliable strategy for the high-performance detection of KET and NK.
