ObjectiveTo explore the inhibitory effect and related molecular mechanisms of Saponin of Schizocapsa plantaginea HanceⅠ (SSPHⅠ) on human nasopharyngeal carcinoma HONE-1 cells. MethodsThe effect of SSPHⅠ on HONE-1 cell viability was detected using the CCK-8 assay. Its inhibitory effect on cell proliferation was evaluated through a colony formation assay. Changes in cell invasion ability were analyzed using the Transwell assay. Intracellular reactive oxygen species (ROS) levels were measured using the DHE fluorescent probe. The extent of intracellular content release was reflected by the LDH release assay. The rate of cell pyroptosis was detected using the Annexin-V/PI double staining method. Changes in the expression of proteins related to the classical pyroptosis pathway were examined by Western Blot. ResultsCCK-8 assay showed that treatment with SSPHⅠ for 24 hours reduced HONE-1 cell viability in a concentration-dependent manner, with an IC50 value of 3.383 μmol/L. In the colony formation assay, the number of HONE-1 cell colonies gradually decreased with increasing concentrations of SSPHⅠ (P<0.01). The Transwell assay revealed that the number of cells migrating through the chamber was reduced following SSPHⅠ treatment (P<0.01). DHE fluorescence probe detection indicated that intracellular ROS fluorescence intensity increased after SSPHⅠ treatment (P<0.001). The LDH release assay showed that LDH activity in the cell supernatant increased with higher concentrations of SSPHⅠ (P<0.001). Annexin-V/PI double staining demonstrated that the proportion of Annexin-V/PI-positive cells increased after SSPHⅠ treatment (P<0.001). Western blot analysis showed that, compared with the control group, the protein expression levels of cleaved-Caspase-1 and GSDMD-N-terminal were upregulated in SSPHⅠ-treated cells (P<0.05), and NLRP3 protein expression levels also increased (P<0.05). ELISA results showed that the levels of IL-1β and IL-18 in the cells increased with higher concentrations of SSPHⅠ (P<0.05). ConclusionSSPHⅠ can induce pyroptosis in nasopharyngeal carcinoma HONE-1 cells by regulating the ROS/NLRP3/Caspase-1 signaling axis, thereby exerting an anti-nasopharyngeal carcinoma effect. This suggests that SSPHⅠ may serve as a potential therapeutic agent for nasopharyngeal carcinoma.

ObjectiveTo explore the mechanism by which Qiangjing tablets (QJT) alleviate the spermatogenic function damage caused by varicocele (VC) based on the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway-mediated oxidative stress. MethodsTen Sprague-Dawley (SD) rats were randomly assigned into a control group and a model group. Pathological examination confirmed the stability of the model. Thirty-six SD rats were randomized into control, model, low-dose (0.23 g·kg-1) QJT, medium-dose (0.46 g·kg-1) QJT, high-dose (0.92 g·kg-1) QJT, and mazhilin (61.7 mg·kg-1) groups, with 6 rats in each group. A rat model of experimental left varicocele (ELV) was established by partially ligating the left renal vein to simulate the human nutcracker syndrome. The rats were administrated with corresponding agents once a day for 28 consecutive days. The in vitro testicular culture model of rats was established through the Transwell chamber method and intervened with QJT-containing sera (2.3, 4.6, and 9.2 g·kg-1). Microscopic observation was carried out for the morphology of the left kidney. A micrometer was used to measure the diameter of the left spermatic vein (LSV). The body weights of rats were recorded weekly, and the epididymis and testis weights were measured. The pathological changes of the testicular tissue was observed via hematoxylin-eosin (HE) staining. The levels of testosterone (T) in the cell culture supernatant and reactive oxygen species (ROS) in the rat testicular tissue were measured by enzyme-linked immunosorbent assay (ELISA). Flow cytometry was employed to determine the ROS content. Immunohistochemical staining was conducted to analyze Keap1, Nrf2, 3β-hydroxysteroid dehydrogenase (3β-Hsd), GATA-binding protein-4 (Gata-4), and proto-oncogene receptor tyrosine kinase (C-kit). The ultrastructure of the tissue was observed by transmission electron microscopy (TEM). Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining. The expression of Keap1, Nrf2, glutathione S-transferase α2 (Gsta2), glutathione S-transferase μ1 (Gstm1), heme oxygenase-1 (HO-1), quinone oxidoreductase 1 (Nqo1), and thioredoxin reductase 1 (Txnrd1) was quantified by Real-time quantitative polymerase chain reaction(Real-time PCR) and Western blot. ResultsCompared with the control group, the ROS content and the percentage of apoptotic cells in the model group were significantly increased (P<0.01), the T concentration was significantly decreased (P<0.01), the mRNA and protein expressions of Keap1 were significantly increased (P<0.01), and the mRNA and protein expressions of Nrf2, Gsta2, Gstm1, HO-1, Nqo1 and Txnrd1 were significantly decreased (P<0.05). Compared with the model group, the ROS content and the percentage of apoptotic cells in each dose group of the Qiangjing Tablets were significantly reduced (P<0.05), and the mRNA and protein expressions of Keap1 were significantly decreased (P<0.05), while the mRNA and protein expressions of Nrf2, Gsta2, Gstm1, HO-1, Nqo1 and Txnrd1 were significantly increased (P<0.05). ConclusionQJT improves sperm motility in the rat model of VC by modulating the Keap1/Nrf2 signaling pathway and reducing oxidative stress injury.

Objective:To explore the surgical efficacy of cervical cerclage with cervical length (CL) <10 mm and emergency cerclage.Methods:From January 2013 to June 2022, a total of 98 singleton pregnant women who underwent ultrasound-indicated cervical cerclage because of CL<10 mm in the second trimester and underwent emergency cervical cerclage because of cervical dilation found by physical examination in Peking University First Hospital were enrolled. The differences in clinical data between the <34 weeks delivery group (25 cases) and the ≥34 weeks delivery group (73 cases) were compared. Meanwhile, according to different cervical status, they were divided into CL<10 mm group (43 cases) and cervical dilatation group (55 cases), and the cervical dilatation group was further divided into cervical dilatation <4 cm group and cervical dilatation ≥4 cm group. The clinical data and pregnancy outcomes of pregnant women with different cervical status were compared.Results:(1) There were significant differences in the proportion of preoperative CL<10 mm and the degree of preoperative cervical dilation between the <34 weeks delivery group and the ≥34 weeks delivery group (all P<0.05). (2) After cervical cerclage, compared with women in the cervical dilatation group, the prolonged gestational age in the CL<10 mm group was longer [(10.5±4.6) vs (14.3±3.4) weeks], the gestational age at delivery was later (median: 35.7 vs 38.0 weeks), the preterm birth rates before 37 and 34 weeks were lower, the late abortion rate was lower [9% (5/55) vs 0 (0/43)], and the newborn birth weight was higher, the differences were statistically significant (all P<0.05). (3) Compared with the cervical dilation ≥4 cm group, the prolonged gestational age of the cervical dilatation <4 cm group was longer [(7.5±5.3) vs (11.1±4.2) weeks], the gestational age at delivery was later (median: 29.2 vs 36.0 weeks), and the birth weight of the newborn was higher (all P<0.05). The late abortion rate of cervical dilatation <4 cm group was lower than that of cervical dilatation ≥4 cm group [7% (3/45) vs 2/10; P=0.220]. Conclusions:Timely cervical cerclage in individuals with CL<10 mm could reduce preterm birth rate before 34 weeks gestation, and the pregnancy outcome is better than that of individuals with cervical dilation. Moreover, the pregnancy outcome of cervical cerclage in women with cervical dilation <4 cm is significantly better than that in women with cervical dilatation ≥4 cm.

Objective:To investigate the prevalence and risk factors of overweight and obesity among Chinese children aged 3-18 years from 11 provinces, antonomous regions, or municipalities.Methods:This national cross-sectional community health survey utilized a multistage stratified cluster-random sampling method to recruit 193 997 nationally representative participants from 11 provinces, autonomous regions, or municipalities between January 2017 and December 2019. All participants underwent physical examinations, and their caregivers completed questionnaires assessing participants′ dietary, lifestyle, familial, and perinatal information. Multilevel multinomial logistic regression models were employed to identify the potential risk factors.Results:The cohort comprised 193 997 children (102 178 boys, 91 819 girls),aged (10±4) years. Overall prevalence rates were 30 574(15.8%)overweight children and 17 217(8.9%) obesity children. Boys exhibited higher overweight and obesity rates than girls (17.0% (17 368/102 178) vs. 14.4% (13 206/102 178), 11.3% (11 553/91 819) vs. 6.2% (5 664/91 819), χ2=249.12,1 578.69,both P<0.001). The detection rates of obesity in Tanner stage 2 and 3 were the highest in boys and girls, with 13.4%(2 231/16 665) and 8.6%(880/10 221) respectively. Risk factors for obesity included parental overweight (paternal OR=2.34 and maternal OR=2.29), annual household income of 100 000-200 000 yuan (compared with<100 000 yuan, OR=1.04), higher paternal education (compared with below high school,high school and a college education OR=1.09,1.14), birth weight >4.0 kg (≤5 and>5 years old OR=1.74, 1.44,respectively), and western food consumption≥1 time/month (compared with<1, 1-2, 3-4,>4 times/month OR=1.36, 1.30, 1.67(≤5 years), 1.19, 1.16, 1.15 (>5 years), respectively) (all P<0.05). Conversely, coarse grain intake≥1 times/week (compared with<1 times/week, every day, 3-4, 1-2 times/week OR=0.74, 0.80, 0.71 (≤5 years), 0.75, 0.87, 0.90(>5 years), respectively, all P<0.05) was associated with reduced obesity risk. Conclusions:Obesity epidemiology in children demonstrates significant heterogeneity across age, gender, geographic regions, and pubertal stages. It is necessary to establish a personalized prevention and control strategy.

Objective:To evaluate the efficacy and safety of the pegaspargase, etoposide, methotrexate, and dexamethasone (PEMD) regimen in patients with early-stage nonupper respiratory digestive tract or advanced extranodal natural killer/T-cell lymphoma (ENKTL) .Methods:This retrospective analysis included 38 patients with newly diagnosed early-stage non-upper respiratory digestive tract or advanced ENKTL who received PEMD regimen for induction chemotherapy at the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2022. Survival outcomes and prognostic factors were examined by Kaplan-Meier, and the Log-rank test was used to compare survival.Results:The study population had a median age of 48 years (range, 26-72 years) and included 30 males (78.9%) and 8 females (21.1%). 7 patients’ age >60 years (18.4%). The Eastern Cooperative Oncology Group (ECOG) performance score was >1 in 7 patients (18.4%) ; 20 patients (52.6%) had elevated lactate dehydrogenase levels; and 37 patients (97.4%) exhibited extranodal involvement. Using the Ann Arbor staging system, 37 patients (97.4%) were classified as stage Ⅲ-Ⅳ. The median number of treatment cycles was 5 (1-6), and the median follow-up duration was 60 months (24 - 101 months). Interim efficacy assessment revealed an overall response rate of 52.7%. At 2 and 4 years, the progression-free survival (PFS) rates were 34.2% (95% CI 22.0%-53.2%) and 25.5% (95% CI 14.7%-44.4%), respectively, and the overall survival rates were 50.0% (95% CI 36.4%-68.7%) and 45.5% (95% CI 31.4%-65.7%), respectively. The risk factors for worse PFS were ECOG performance score >1 [ HR=3.711 (95% CI 1.494-9.218), P=0.005]; bone marrow infiltration [ HR=2.251 (95% CI 1.026 - 4.938), P=0.043]; and Prognostic Index for Natural Killer/T-Cell Lymphoma score of 3 - 5 [ HR=2.350 (95% CI 1.009 - 5.476), P=0.048]. Multivariate analysis identified ECOG performance score >1 as an independent risk factor for PFS [ HR=7.971 (95% CI 2.222 - 28.591), P=0.001]. The main adverse effect was anemia in 31 patients (81.6%) . Conclusion:The PEMD regimen was safe and effective for patients with newly diagnosed early-stage non-upper respiratory digestive tract or advanced ENKTL.
9.Research advances in monogenic hereditary cerebral small vessel disease
Journal of Apoplexy and Nervous Diseases 2025;42(10):947-954
Monogenic hereditary cerebral small vessel disease (CSVD) is a group of genetic disorders characterized by cerebrovascular lesions, including cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy, COL4A1 and COL4A2-related CSVD, and other rare types such as retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations and leukoencephalopathy with calcifications and cysts. These diseases are often caused by specific gene mutations and exhibit highly heterogeneous pathological mechanisms and clinical manifestations, including inflammatory response, abnormal gene expression, and microangiopathy. The advances in imaging findings and biomarkers have provided new methods for early diagnosis, while treatment strategies include stem cell therapy, immunotherapy,gene editing, and molecular targeted therapy. However, further studies are needed to develop individualized treatment regimens for different subtypes. This article reviews the important advances in the pathogenesis, clinical features, diagnostic methods, and treatment modalities of monogenic hereditary CSVD in recent years, in order to provide guidance for future research and clinical practice.

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.
