Objective: To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies. Methods: From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects. Results: Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05). Conclusion Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

Objective: Biological potency assay, as a core component of biopharmaceutical quality control, directly influences drug efficacy assessments through the reliability of the methods. While ELISA-based potency assays accurately characterize drug-target interactions, traditional manual operations are often limited by cumulative operational errors, high variability, human errors, and low throughput.
Methods: A fully automated ELISA platform using the Microlab STARplus system was introduced by integrating high-precision pipetting modules with external devices.
Results: This platform not only meet accuracy and precision requirements but also significantly reduces variability compared to manual operations.
Conclusion: The platform enables a seamless, end-to-end workflow-from sample processing to detection, and standardized protocols and data traceability functions to effectively ensure data integrity.

Objective:To investigate the applicability and surgical effect of direct horizontal suture in the repair of defects after the excision of eyelid nevus.Methods:The clinical data of patients with eyelid nevus who were admitted to Department of Facial and Neck Plastic Surgery, Plastic Surgery Hospital of Chinese Academy of Medical Sciences from March 2015 to March 2023 were retrospectively analyzed. After the eyelid nevus was removed, the defect was closed by horizontal suture parallel to the eyelid margin. In the preoperative simulation suture scheme, one or more horizontal lines were marked on the eyelid skin according to the scope of the nevus. The intersection points of the horizontal lines and the edges of the nevus were marked for simulated suturing. If the marked points aligned horizontally, direct suturing was applied. After 3 months of postoperative follow-up, the therapeutic effect was evaluated based on eyelid function (classified as excellent, good and poor), cosmetic effects (classified as excellent, good and poor) and patient satisfaction (classified as very satisfactory, satisfactory and dissatisfactory). At the same time, the effect of different wound length (<1 cm, 1-2 cm, >2 cm) on the therapeutic effect was also analyzed. SPSS 27.0 software was used for statistical analysis of the data. The counting data were represented by examples and percentages, and Kruskal-Wallis H test was used for comparison between groups. P<0.05 indicated that the difference was statistically significant. Results:A total of 71 patients were enrolled, including 30 males and 41 females. Aged 4 to 35 years old, with an average age of 15 years old. The lesions involved the upper eyelid in 47 cases, the lower eyelid in 14 cases, and co-involved in 10 cases. Lesion areas ranged from 0.5 cm×0.5 cm to 2.3 cm×2.0 cm. None of the lesions involved the palpebral margin and conjunctiva, and the depth did not reach the orbicularis oculi muscle. Immediately after the operation, all the patients had different degrees of eyelid deformation, and some severe patients had difficulty opening their eyes. The above symptoms were relieved within 7 days to 3 months after the operation, and eventually the eyelid movement returned to normal, leaving only mild scarring. In cases where the eyelid nevus was close to or involved the eyebrow area, eyebrow shape changed after surgery, and it gradually returned to normal after 1 month. Some patients with part of the eyebrow defect were able to improve their appearance through eyebrow tattoos, eyebrow transplatation and other methods. The eyelid function of 71 patients was excellent. The evaluation of cosmetic effect, 41 cases (58%) were excellent, and 30 cases (42%) were good. The evaluation of patient satisfaction, 56 cases (79%) were very satisfied, and 15 cases (21%) were satisfied. Statistical analysis showed that with the increase of the horizontal length of the wound, the cosmetic effect and patient satisfaction would be affected to a certain extent, but the differences were not statistically significant ( P>0.05). Conclusion:For eyelid nevus excision defects that can be closed horizontally, direct suturing method should be considered priority. This method is simple to perform, offers stable postoperative effects, and leads to high patient satisfaction.

BACKGROUND: The proportion of patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations is relatively high in China. However, these patients currently lack significant benefits from available neoadjuvant treatment options. This study aims to explore the potential application value of neoadjuvant targeted therapy by evaluating its efficacy and safety in patients with EGFR-mutant resectable lung adenocarcinoma. METHODS: A multicenter retrospective study was used to analyze the treatment effect of patients with stage IIA-IIIB EGFR-mutant lung adenocarcinoma who underwent surgical resection after receiving neoadjuvant targeted therapy from July 2019 to October 2024. RESULTS: A total of 24 patients with EGFR-mutant lung adenocarcinoma from three centers were included in this study. All patients successfully underwent surgery and achieved R0 resection of 100.0%. The objective response rate (ORR) was 83.3% (20/24) . The major pathologic response (MPR) rate was 37.5% (9/24), with 2 patients (8.3%) achieving pathological complete response (pCR). During neoadjuvant therapy, 13 out of 24 patients (54.2%) experienced adverse events of grade 1-2, with no occurrences of ≥ grade 3. The most common treatment-related adverse events were rash (n=4, 16.7%), mouth sores (n=2, 8.3%), and diarrhea (n=2, 8.3%). The median follow-up time was 33.0 months, no deaths occurred in all patients, and the overall survival (OS) rate was 100.0%. The 1-year disease-free survival (DFS) rate was 91.1%, and the 2-year DFS rate remained at 86.2%. CONCLUSIONS The application of neoadjuvant targeted therapy in patients with EGFR-mutant resectable lung adenocarcinoma is safe and feasible, and is expected to become a highly promising neoadjuvant treatment option for the patients with EGFR-mutant lung adenocarcinoma.

Objective:To explore the correlation between weekend moderate-to-vigorous physical activity(MVPA), weekday sedentary behavior(SB)and the risk of frailty in the elderly population monitored by wearable devices, and to provide a scientific basis for lifestyle interventions for frailty in the elderly.Methods:This study was based on the data of the UK Biobank from 2013 to 2015.A cross-sectional study design was adopted, and 33, 212 elderly people aged 60 and above with complete physical activity monitoring data were selected.The Frailty Index(FI)constructed by the deficit accumulation method was used to assess the frailty status.The correlation between the combined effect of weekday SB and weekend MVPA and the frailty status was analyzed, and the differences between genders were explored.Results:There were significant differences in physical activity indicators among the elderly with different frailty statuses.As the degree of frailty increased, the MVPA-related indicators showed a downward trend, while the weekday SB time gradually increased.There were sex differences in physical activity patterns and frailties.Compared with women, men had longer SB time on weekdays, lower metabolic equivalent of weekly MVPA consumption, and higher MVPA time on weekends, but the frailties index of women was slightly higher than that of men.After adjusting for confounding factors, the frailty risks for men and women in the subgroup with the lowest weekday SB and the highest weekend MVPA duration decreased by 46.9% and 59.8%, respectively( P<0.001)when compared to the highest-risk group. Conclusions:Based on the monitoring data from wearable devices, elderly individuals who reduced their SB time during weekdays and increased their MVPA time on weekends were associated with a lower risk of frailty, especially among women; which providing a new perspective for lifestyle-based intervention strategies for frailty among the elderly.

The activation proteins released by fibroblasts in the tumor microenvironment regulate tumor growth, migration, and treatment response, thereby influencing tumor progression and therapeutic outcomes. Owing to the proliferation and metastasis of tumors, fibroblast activation protein (FAP) is typically highly expressed in the tumor stroma, whereas it is nearly absent in adult normal tissues and benign lesions, making it an attractive target for precision medicine. Radiolabeled agents targeting FAP have the potential for targeted cancer diagnosis and therapy. This comprehensive review aims to describe the evolution of FAPI-based radiopharmaceuticals and their structural optimization. Within its scope, this review summarizes the advances in the use of radiolabeled small molecule inhibitors for tumor imaging and therapy as well as the modification strategies for FAPIs, combined with insights from structure-activity relationships and clinical studies, providing a valuable perspective for radiopharmaceutical clinical development and application.

Astragali Radix (AR) and Notoginseng Radix et Rhizoma (NR) are frequently employed in cardiovascular disease treatment. However, the efficacy of the AR-NR medicine pair (AN) in improving cardiac remodeling and its underlying mechanism remains unclear. This study aimed to evaluate AN's cardioprotective effect and potential mechanism on cardiac remodeling using transverse aortic constriction (TAC) in mice and angiotensin II (Ang II)-induced neonatal rat cardiomyocytes (NRCMs) and fibroblasts in vitro. High-performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry (HPLC-Q-TOF-MS/MS) characterized 23 main components of AN. AN significantly improved cardiac function in the TAC-induced mice. Furthermore, AN considerably reduced the serum levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), cardiac troponin T (CTn-T), and interleukin-6 (IL-6) and mitigated inflammatory cell infiltration. Post-AN treatment, TAC-induced heart size approached normal. AN decreased cardiomyocyte cross-sectional area and attenuated the upregulation of cardiac hypertrophy marker genes (ANP, BNP, and MYH7) in vivo and in vitro. Concurrently, AN alleviated collagen deposition in TAC-induced mice. AN also reduced the expression of fibrosis-related indicators (COL1A1 and COL3A1) and inhibited the activation of the transforming growth factor-β1 (TGF-β1)/mothers against decapentaplegic homolog 3 (Smad3) pathway. Thus, AN improved TAC-induced cardiac remodeling. Moreover, AN downregulated p-dynamin-related protein (Drp1) (Ser616) expression and upregulated mitogen 2 (MFN-2) and optic atrophy 1 (OPA1) expression in vivo and in vitro, thereby restoring mitochondrial fusion and fission balance. In conclusion, AN improves cardiac remodeling by regulating mitochondrial dynamic balance, providing experimental data for the rational application of Chinese medicine prescriptions with AN as the main component in clinical practice.
