Pegylated interferon α-2b （PEG-IFN-α-2b） is currently a first-line drug for the treatment of chronic hepatitis B virus infection and is widely used in clinical practice. This drug has multiple effects of inhibiting viral replication， regulating immunity， and improving liver function， and some patients can achieve clinical cure. However， it often causes various adverse reactions during treatment， which are important factors for compromising treatment compliance and efficacy. This article systematically reviews the adverse reactions and their mechanisms during PEG-IFN-α-2b therapy for chronic hepatitis B， including influenza-like symptoms， peripheral blood cytopenia， thyroid dysfunction， and neuropsychiatric symptoms， and it also summarizes the monitoring and management strategies for these adverse reactions， in order to provide evidence-based guidance for clinical decision-making and emphasize the importance of individualized treatment.

Abstract Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

Gastric cancer has high incidence and mortality rate. Chemotherapy is the first-line treatment for gastric cancer and has achieved considerable success. However, due to genetic variations and tumor heterogeneity, the effectiveness of chemothrapy drugs varies among different patients. Therefore, accurate assessment of patient’s sensitivity to chemotherapy drugs is crucial for personalized treatment. Gastric cancer organoids serve as effective tools for predicting patient’s sensitivity to chemotherapy drugs. This review summarizes the applications and related research progress of gastric cancer organoids in determining chemotherapy drug sensitivity, discusses the strengths and limitations of organoid models, and proposes outlooks for future research directions, hoping that organoids can provide more effective personalized treatment options and a greater range of drug choices for gastric cancer treatment.

(±)-Talapyrones A-F (1-6), six pairs of dimeric polyketide enantiomers featuring unusual 6/6/6 and 6/6/6/5 ring systems, were isolated from the fungus Talaromyces adpressus. Their structures were determined by spectroscopic analysis and HR-ESI-MS data, and their absolute configurations were elucidated using a modified Mosher's method and electronic circular dichroism (ECD) calculations. (±)-Talapyrones A-F (1-6) possess a 6/6/6 tricyclic skeleton, presumably formed through a Michael addition reaction between one molecule of α-pyrone derivative and one molecule of C₈ poly-β-keto chain. In addition, compounds 2/3 and 4/5 are two pairs of C-18 epimers, respectively. Putative biosynthetic pathways of 1-6 were discussed.

Purpose To explore the role of translesion synthesis-related gene NmrA like redox sensor 1(NMRAL1)in the development of papillary thyroid carcinoma(PTC).Methods Bioinformatics analysis was em-ployed to investigate the expression of the NMRAL1 gene across various cancer types and its correlation with prognosis.Immunohistochemistry was utilized to analyze the expression pattern of NMRAL1 in PTC and conduct clinicopathological correlation analysis.Additionally,stable cell lines overexpressing NMRAL1 were established in TPC-1 cells.The effects of NMRAL1 overexpression on cell proliferation,migration,and invasion of TPC-1 and Nthy-ori 3-1 cells were assessed using CCK-8 assay,clonogenic assay,Transwell assay,and scratch assay,respectively.Furthermore,RT-qPCR experiments were conducted to investigate the regulatory effect of NMRAL1 on the expression of genes associated with translesion DNA synthesis.Results Bioinformatics analysis revealed that NMRAL1 was highly expressed in all 26 types of tumors compared to normal tissues in the TCGA x GTEx dataset.Patients with high expression of NMRAL1 in thyroid cancer had significantly lower survival rates than those with low expression(P＜0.05).In the immunohisto-chemical validation of 30 PTC samples,NMRAL1 had a positive rate of 73.33％,in PTC tissues,while it was not ex-pressed in adjacent normal thyroid tissues.The staining intensity scores of NMRAL1 in PTC and adjacent tissues exhib-it significant differences(P＜0.000 1).High expression of NMRAL1 was associated with the size of the tumor(P=0.027 4)and lymph node metastasis(P=0.044 1).In vitro functional experiments revealed a significant enhance-ment in both cell proliferation and migration/invasion capacities upon overexpression of NMRAL1(P＜0.05).Moreo-ver,mRNA and protein expression levels of translesion synthesis-related genes were upregulated(P＜0.001).Con-clusion NMRAL1 promotes proliferation and migration of thyroid carcinoma cells,suggesting that this function may be achieved by enhancing DNA damage repair capacity,thereby improving the survival of damaged cells.

Objective:To investigate the effects of Jianpi Rougan Xifeng Decoction on the behaviors and the Ca 2+ -CaM-CaMK Ⅱ signaling pathway in the striatum of rats with tic disorder models. Methods:Seventy-two SPF-grade SD male rats were randomly divided into blank group, model group, tiapride group (15.93 mg/kg, intragastric administration), low-dose (4.32 g/kg, intragastric administration), medium-dose (8.64 g/kg, intragastric administration) and high-dose (17.28 g/kg, intragastric administration) Jianpi Rougan Xifeng Decoction groups, with 12 rats in each group. Rats in the blank group and model group were gavaged with 0.5 mg/kg of distilled water while rats in other 4 groups were gavaged with corresponding drugs, all rats were gavaged once a day for 28 days.The evaluations of motor behavior and stereotyped behavior were conducted using the Kadasah scoring method and the Diamond scoring method. Calcium content in the striatum was detected using a calcium assay kit. Immunohistochemical analysis was employed to detect the expression of dopamine transporter (DAT) and inositol 1, 4, 5-triphosphate (IP3) in the striatum of rats. Western blot was used to assess the expression of calmodulin (CaM) and calcium/calmodulin-dependent protein kinase Ⅱ (CaMK Ⅱ) in the striatum. RT-PCR was utilized to detect the expression of CaM and CaMK Ⅱ mRNA in the striatum. All data were processed using SPSS 26.0 software, and comparisons among multiple groups were performed using one-way ANOVA and Kruskal-Wallis test.Results:(1) After four weeks of pharmacological intervention, statistically significant differences were observed in the locomotor activity scores and stereotyped scores among the six groups of rats ( H=41.20, 44.24, both P<0.01). Specifically, the locomotor activity scores(3.00(3.00, 3.25), 1.00(0.75, 1.25), 1.00(0.75, 2.00), 1.00(0, 1.00)) and stereotyped scores(3.00(3.00, 4.00), 1.00(0.75, 2.00), 2.00(0.75, 2.00), 1.00(0, 1.25)) in the tiapride group and the medium- and high-dose Jianpi Rougan Xifeng Decoction groups were significantly lower than those in the model group (all P<0.01). (2) Results from the calcium assay kit revealed statistically significant differences in striatal calcium content among the six groups of rats ( F=146.67, P<0.01). The calcium content in the tiapride group and the medium- and high-dose Jianpi Rougan Xifeng Decoction groups was significantly lower than that in the model group (all P<0.01). Additionally, the calcium content in the medium-dose ((0.40±0.02)mmol/g) and high-dose ((0.30±0.03)mmol/g) Jianpi Rougan Xifeng Decoction groups was lower than that in the low-dose group ((0.48±0.02)mmol/g) (both P<0.01). (3) Immunohistochemical results showed that there were statistically significant differences in the mean optical density values of DAT and IP3 in the striatum among the six groups of rats ( F=25.57, 154.98, both P<0.01). The IP3 mean optical density in the tiapride group and the Jianpi Rougan Xifeng Decoction groups with medium and high doses exhibited lower values compared to the model group (all P<0.05), whereas the DAT mean optical density displayed higher values in these groups compared to the model group (all P<0.05). The low-dose Jianpi Rougan Xifeng Decoction group also exhibited a lower optical density value of IP3 compared to the model group( P<0.05). The optical density values of IP3 (2.68±0.21, 2.40±0.22) in the medium-dose and high-dose Jianpi Rougan Xifeng Decoction groups were lower than that in the low-dose group (4.27±0.23) (both P<0.01). (4) Western blot results indicated that there were statistically significant differences in the protein expression levels of CaM and CaMK Ⅱ in the striatum among the six groups of rats ( F=233.03, 118.60, both P<0.01). The protein expression levels of CaM and CaMK Ⅱ in the tiapride group and the low-dose, medium-dose, and high-dose Jianpi Rougan Xifeng Decoction groups were lower than those in the model group (all P<0.01). The protein expression levels of CaM (1.02±0.06, 0.84±0.02) and CaMK Ⅱ (0.48±0.03, 0.40±0.02) in the medium-dose and high-dose Jianpi Rougan Xifeng Decoction groups were lower than those in the low-dose group (1.21±0.03, 0.57±0.02)) (all P<0.05). Additionally, the protein expression level of CaM in the high-dose Jianpi Rougan Xifeng Decoction group was lower than that in the medium-dose group( P<0.05).(5) The RT-PCR results indicated significant variations in the mRNA expression levels of CaM and CaMK Ⅱ within the striatum across the six groups rats ( F=30.54, 20.78, both P<0.01). The mRNA expression levels of CaM and CaMK Ⅱ in the tiapride group and the high-dose Jianpi Rougan Xifeng Decoction group were lower than those in the model group (both P<0.05). The mRNA expression levels of CaMK Ⅱ (1.38±0.17) in the high-dose Jianpi Rougan Xifeng Decoction group were lower than those in the low-dose group (1.99±0.27) ( P<0.01). Conclusion:Jianpi Rougan Xifeng Decoction can improve locomotor activity and stereotyped behavior in rats with tic disorder model. The mechanism may be through inhibiting the Ca 2+ -CaM-CaMK Ⅱ signaling pathway and regulating the expression of DAT and IP3, thereby modulating the release and recovery of dopamine and reducing the occurrence of tic symptoms.

Objective:To investigate the prevalence and severity of symptom burden among long-term survivors of oropharyngeal cancer after radiotherapy, to identify core symptom clusters, and to explore their correlation with quality of life.Methods:A previous retrospective study was conducted by the Cancer Hospital, Chinese Academy of Medical Sciences on patients with oropharyngeal cancer who underwent radiotherapy between January 2010 and December 2020. Patients who were still alive as of December 2023 were further followed and analyzed. From December 2023 to August 2024, symptom burden and quality of life were assessed using the Chinese version of the MD Anderson Symptom Inventory–Head and Neck Module (MDASI-HN) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ). Exploratory factor analysis (principal component analysis with Promax rotation) were used to identify symptom clusters. Spearman correlation analysis was performed to explore the relationship between total symptom cluster scores and standardized domain scores of quality of life. Multivariate linear regression analysis was further employed to determine the relationship between identified symptom clusters and overall quality of life.Results:A total of 273 patients were included, with a median follow-up duration of 6.2 years (range: 3.5-14.5 years) and a median age of 61 years (range: 27-88 years) at follow-up. The top 5 incidence rates of symptom reported by patients were mucus problems in the mouth or throat (147 cases, 53.8%), dental or gum issues (143 cases, 52.4%), xerostomia (140 cases, 51.3%), difficulty swallowing or chewing (95 cases, 34.8%), and taste disturbance (79 cases, 28.9%). Among them, xerostomia was the most serious symptom. The most frequently reported interference was impact on work (including household chores) (55 cases, 20.1%). Exploratory factor analysis identified 3 symptom clusters: fatigue-nausea cluster, eating-voice cluster, and xerostomia-sleep cluster, all of which were significantly correlated with lower overall quality of life of patients (all P<0.001). Conclusion:Long-term survivors of oropharyngeal cancer after radiotherapy experience substantial symptom burden. The fatigue-nausea, eating-voice, and xerostomia-sleep clusters are the core symptom clusters impacting quality of life.

Objective:To explore the prognostic value of monocyte to high-density lipoprotein cholesterol (HDL-C) ratio (MHR) in assessing patients with heart failure with reduced ejection fraction (HFrEF).Methods:Patients with HFrEF (LVEF<40%) admitted to the TEDA International Cardiovascular Disease Hospital between 2 January 2019 and 15 January 2023 were selected. The MHR levels were recorded at admission in patients with HFrEF who were followed up regularly for 12 months. The major adverse cardiovascular events (cardiac death and readmission for heart failure) were defined as poor prognosis. Multivariate Cox regression was used to analyze factors associated with poor prognosis. The receiver operator characteristic (ROC) curves were used to assess the diagnostic value of MHR for poor prognosis. The DeLong test was used to analyze whether there was a difference in the effectiveness of MHR and BNP for detecting poor prognosis. The critical value grouping for poor prognosis was evaluated by MHR, and survival analyses were performed using Kaplan-Meier.Results:A total of 286 subjects were enrolled in the study, including 206 males and 80 females, with a median age ( Q1, Q3) of 67 (58, 74) years. Multivariate Cox regression showed that MHR ( HR=1.482, 95% CI:1.015-2.164) and BNP ( HR=1.001, 95% CI:1.000-1.001) were associated with poor prognosis in patients with HFrEF. The area under the ROC curve for the adjunctive diagnostic value of MHR, BNP and the combination of both for poor prognosis in patients with HFrEF was 0.709, 0.738 and 0.769, respectively. The critical values were 0.486, 1 090 pg/ml and 0.41, respectively. The DeLong test showed no differences in the validity of MHR, BNP and their combination for detecting poor prognosis. Kaplan Meier survival analysis of 12-month follow-up showed that the time for poor prognosis in HFrEF patients with MHR>0.486 group (8.645 months) was significantly shorter than that in MHR≤0.486 group (10.296 months, P<0.001), and the risk of poor prognosis in MHR>0.486 group was 2.843 times higher than that in MHR≤0.486 group ( HR=2.843, 95% CI:1.867-4.327). Conclusion:MHR can be an indicator of poor prognosis in patients with HFrEF.
