Objective: To explore the long term trend of forced vital capacity to weight index (FWI) among Chinese Han students aged 7-18 from 2000 to 2019, and to predict its changes over the next decade, so as to provide scientific evidences for targeted health interventions and school health policies. Methods: Based on the data of the five Chinese National Surveys on Students Constitution and Health conducted from 2000 to 2019, a total of 216 500, 233 565, 215 267, 214 256 and 212 632 Han students aged 7-18 were included, respectively. The long term trend of FWI among students was analyzed, and the GM (1,1) grey model was used to predict FWI changes over the next decade. Subgroup analyses were conducted by sex, age, and urban-rural residence. Results: The FWI levels of Chinese Han students aged 7-18 were (55.30±11.47)(47.43±11.92)(48.11±12.46)(48.75±12.81)(50.93±13.11)mL/kg in 2000, 2005, 2010, 2014, and 2019, respectively. The FWI of Chinese Han students showed a decreasing then increasing trend from 2000 to 2019, reaching the lowest point of approximately 47.03 mL/kg around 2006, and was projected to recover to 52.88 mL/kg by 2029. Boys had higher FWI for each year and the total level than girls from 2000 to 2019( t =72.58-304.66), and the decline between 2000 and 2005 was smaller in boys (13.1%) than in girls (15.4%). However, the gender gap gradually narrowed and was projected to reduce to 5.36 mL/kg by 2029. FWI increased with age, with the largest difference observed in 2014 between the 7-9 and 16-18 age groups (8.62 mL/kg). Before 2014, urban boys had slightly lower FWI than rural boys; the gap narrowed thereafter, and their FWI levels were expected to become similar by 2029. Urban girls generally had higher FWI than rural girls, and the urban-rural gap showed an increasing trend. By 2029, the largest difference was projected to occur in the 13-15 age group, reaching 7.74 mL/kg. Conclusions The FWI of Chinese Han students showed a trend of initial decline followed by a gradual increase from 2000 to 2019, with notable differences across sex, age, and urban-rural residence. Greater attention should be paid to the respiratory health of rural girls, and effective measures should be taken to reduce urban-rural disparities.

The investigator-initiated trials （IIT）， as a widely existing form of clinical research both domestically and internationally， have attracted the attention of governments around the world due to the potential legal risks and issues they may cause， and the trend of legal supervision has gradually strengthened. The legal regulation of IIT in China is still in its early stages， with numerous legal issues that need to be clarified and sorted out. Based on the domestic and international legal reviews of IIT， this paper systematically sorted out the current situation of legal supervision of IIT in China and examined the existing issues， including weak legislative rules， incomplete regulatory systems， imperfect protection rules for research participants and informed consent systems， inadequate regulation of conflicts of interest management， and lax legal supervision of ethical review. Furthermore， this paper proposed suggestions for legal regulation of IIT from three perspectives， including strengthening legislation and emphasizing regulation， improving the mechanism for protecting research participants’ rights and interests， and balancing the legalization of IIT and the scientific development of clinical research， with a view to providing references for legal regulatory paths of IIT in China.

Background Existing studies have confirmed that fine particulate matter (PM_2.5)is one of the important factors inducing pulmonary fibrosis. Pulmonary fibrosis is the terminal stage of a major category of lung diseases characterized by the destruction of tissue structure, and eventually leading lung ventilation and ventilation dysfunction. No effective pulmonary fibrosis treatment is available yet. Objective To investigate the protective effect of salidroside on pulmonary fibrosis induced by the exposure of PM_2.5 and its molecular mechanism. Methods Seventy 7-week-old male C57BL/6 mice were randomly divided into four groups: control group (intratracheal instillation of normal saline + saline by gavage, n=25), Sal group (intratracheal instillation of normal saline + Sal 60 mg·kg⁻¹ by gavage, n=10), PM_2.5 group (intratracheal instillation of PM_2.5 5 mg·kg⁻¹ + saline by gavage, n=10), and Sal + PM_2.5 group (intratracheal instillation of PM_2.5 5 mg·kg⁻¹ +Sal 60 mg·kg⁻¹ by gavage, n=10). The mice were administered by gavage once daily, intratracheal instillation once every 3 d, and every 3 d constituted an experimental cycle. At the end of the 26-30th cycles, 3 mice in the control group and 3 mice in the PM_2.5 group were randomly sacrificed, and the lung tissues were collected for Masson staining to verify whether the pulmonary fibrosis model was successfully established. After 30 cycles, the model was successfully constructed. After 1 week of continuous observation, the mice were sacrificed, and the blood and lung tissues of the mice were collected to make lung tissue sections. Assay kits were correspondingly employed to detect oxidative stress indicators such as serum malondialdehyde (MDA) and superoxide dismutase (SOD). Western blotting was used to detect the expression of fibrosis-related proteins (Collagen-III, α-SMA), mitochondrial dynamics-related proteins (MFN1, Drp1), and mitophagy-related proteins (PINK1, Parkin, and LC3). Results Compared with the control group, the weight gain rate of the PM_2.5 group was slowed down (P<0.05), which was alleviated by the Sal intervention (P<0.05). The lung coefficient increased after the PM_2.5 exposure (P<0.05), which was alleviated by Sal intervention. Compared with the control group, the PM_2.5 group showed severe alveolar structure damage, inflammatory cell infiltration, and blue collagen deposition, and significantly increased the lung injury score, collagen volume fraction (CVF), Szapiel score, and Ashcroft score (P<0.05), as well as serum oxidative stress levels (P<0.05). The protein expression levels of Collagen-III, α-SMA, Drp1, PINK1, Parkin, and LC3 II/I were increased (P<0.05), and the expression of MFN1 was decreased (P<0.05). Compared with the PM_2.5 group, the Sal intervention alleviated lung injury, reduced inflammatory cell infiltration and collagen deposition, showing decreased lung injury score, CVF, Szapiel score, and Ashcroft score (P<0.05), and decreased serum oxidative stress levels (P<0.05); the protein expression levels of Collagen-III, α-SMA, PINK1, Parkin, and LC3 II/I were decreased (P<0.05), the expression level of Drp1 was decreased, and the expression level of MFN1 was increased. Conclusion In the process of pulmonary fibrosis induced by PM_2.5 exposure in mice, Sal may affect mitochondrial autophagy through PINK1/Parkin pathway and play a protective role. The specific mechanism needs to be further verified.

OBJECTIVES: To elucidate the molecular mechanism by which villin-like protein VILL (VILL) inhibits proliferation of nasopharyngeal carcinoma (NPC) cells. METHODS: Co-immunoprecipitation (CO-IP) assay, mass spectrometry, Western blotting, immunofluorescence staining, and GST pull-down assay were employed to identify and confirm the protein interacting with VILL that had the highest abundance in NPC cell lines. Transgenic experiments were conducted in both NPC cell lines and nude mice to validate the regulatory role of VILL and its target protein in NPC proliferation. Immunohistochemistry was utilized to assess the correlation of the expression levels of VILL and its target protein in clinical tissue specimens of NPC with the clinical features of the patients. RESULTS: In NPC cell lines (HONE1 EBV and S18), VILL was found to interact most abundantly with the E3 ubiquitin ligase LMO7, and both proteins co-localized in the cytoplasm with direct interactions. Overexpression of LMO7 partially counteracted the inhibitory effect of VILL on NPC cell proliferation. The expression of VILL was significantly downregulated in 136 NPC tissue samples compared to 67 non-cancerous nasopharyngeal tissues (P<0.00001) with close correlation with clinical T stage (P=0.04), N stage (P=0.01), and M stage (P=0.013), whereas LMO7 was highly expressed in all the NPC tissues. CONCLUSIONS VILL overexpression inhibits NPC proliferation probably by suppressing the oncogenic function of LMO7.

OBJECTIVES: To investigate the inhibitory effect of multimerin-2 (MMRN2) overexpression on growth and metastasis of cutaneous melanoma cells. METHODS: Clinical data of patients with cutaneous melanoma were obtained from the GEO database to compare MMRN2 expressions between normal and tumor tissues. A protein-protein interaction network was constructed using the STRING database, and the intersecting genes from GEPIA2.0 were subjected to GO and KEGG enrichment analysis. The prognostic relevance of MMRN2 expression level was assessed using Cox regression and "timeROC". The correlations of MMRN2 expression level with immune infiltration and angiogenesis-related genes were analyzed using GSCA database and the ssGSEA algorithm. Colony-forming assay, Transwell assay, and wound healing assay were used to examine the changes in proliferation and migration of cultured cutaneous melanoma cells following MMRN2 knockdown. In a mouse model bearing cutaneous melanoma xenograft, the effect of MMRN2 knockdown on vital organ pathologies, survival of the mice and GM-CSF, CXCL9, and TGF‑β1 protein expressions were analyzed. RESULTS: MMRN2 was significantly upregulated in metastatic cutaneous melanoma (P<0.001). Protein interaction network analysis identified 15 intersecting genes, which were enriched in endothelium development and cell-cell junctions. In patients with cutaneous melanoma, a high MMRN2 expression was correlated with a poor prognosis, an advanced T stage, a greater Breslow depth, and ulceration (P<0.05). MMRN2 expression level was strongly correlated with 24 immune cell types (P<0.001), fibroblasts, endothelial cells, and expressions of the pro-angiogenic genes (KCNJ8, SLCO2A1, NRP1, and COL3A1; P<0.001). In cultured B16F10 cells, MMRN2 knockdown significantly suppressed cell proliferation, migration and invasion and caused remo-deling of the immunosuppressive microenvironment. CONCLUSIONS MMRN2 overexpression drives progression of cutaneous melanoma by enhancing tumor metastasis, angiogenesis and immune evasion, highlighting its potential as a therapeutic target for melanomas.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:To analyze the value of 68Ga-fibroblast activation protein inhibitor (FAPI)-04 PET/CT in the detection of myocardial injury in patients treated with anti-tumor therapy. Methods:A retrospective study was conducted on 164 patients who underwent 68Ga-FAPI-04 PET/CT to evaluate the efficacy of anti-tumor therapy in Renji Hospital, School of Medicine, Shanghai Jiao Tong University between August 2021 and March 2024. The patients were divided into 68Ga-FAPI-04-positive group ( n=63, 36 males, 27 females, age (66.7±9.6) years) and 68Ga-FAPI-04-negative group ( n=101, 42 males, 59 females, age (55.2±14.1) years) based on the uptake of left ventricular myocardium (LVM). Moreover, FAPI-04 uptake was analyzed based on different types and locations, and the corresponding SUV max differences were analyzed by Kruskal-Wallis rank sum test. The differences of SUV max between 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were analyzed by Mann-Whitney U test. The clinical factors such as gender, age, body mass index (BMI), previous history of coronary heart disease, left ventricular ejection fraction (LVEF), smoking history, hypertension, diabetes, cancer types and immune checkpoint inhibitors (ICIs) treatment were collected, and their predictive values for LVM 68Ga-FAPI-04 uptake were investigated by the binary logistic regression analysis. Results:Fifty patients of the 68Ga-FAPI-04-positive group (79.4%, 50/63) showed focal uptake of LVM, 7 patients (11.1%, 7/63) showed multifocal myocardial uptake, and 6 patients (9.5%, 6/63) showed diffuse myocardial uptake. A total of 127 uptake lesions were found, and most of them were located in the septum (37.8%, 48/127). The SUV max of LVM in 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were 4.00(3.10, 5.40) and 1.31(1.20, 1.40) respectively ( z=-10.82, P<0.001). Differences of the SUV max among focal uptake group, multifocal myocardial uptake group, and diffuse myocardial uptake group were not significantly different (4.00(3.00, 5.10) vs 7.60(3.60, 9.30) vs 3.95(3.05, 5.05); H=3.81, P=0.149). There is no statistically significant difference either in FAPI uptake among different sites of LVM ( H=1.51, P=0.825). Age, previous history of coronary heart disease, BMI, LVEF and ICIs treatment were independent predictive factors for positive 68Ga-FAPI-04 uptake in the LVM (odds ratio ( OR) values: 0.87-10.43, all P<0.05). Conclusion:68Ga-FAPI-04 PET/CT is a potential new imaging method for the visualization of myocardial injury in patients with anti-tumor therapy.

Objective:To summarize the clinical and EEG characteristics of children with self-limited epilepsy with centrotemporal spikes (SeLECTS), and explore the risk factors for comorbid attention-deficit hyperactivity disorder (ADHD).Methods:Demographic and medical history data, seizure characteristics, EEG data, and treatment information of 122 children with SeLECTS admitted to Department of Neurology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from July 2020 to March 2024 were collected. Based on Swanson, Nolan and Pelham-IV Rating Scale (SNAP-IV) results, these patients were divided into comorbid ADHD group ( n=64) and non-ADHD group ( n=58); the clinical data and EEG characteristics (location and lateralization of discharges, synchronicity of bilateral discharges, period of discharges, spike wave frequency and special waveforms) of the patients between the 2 groups were compared to analyze the risk factors for comorbid ADHD. Results:(1) In 122 SeLECTS children, 70 (57.38%) were males and 52 (42.62%) were females; onset age was (7.50±1.98) years (3-12 years); 72.95% (89/122) patients had seizures only within 1 h after falling asleep, 9.84% (12/122) had seizures only 1-2 h before awakening in the morning, 9.84% (12/122) had seizures both after falling asleep and before awakening in the morning; duration of a single episode was (116.60±89.68) seconds (10-600 seconds). (2) Background activity in EEG showed no obvious abnormalities; the discharges were located in the central temporal region in 93.20% (96/103) patients and in the central temporal region and other brain regions (including frontal region, anterior head, bilateral occipital midline and bilateral cerebral hemispheres) in 6.80% (7/103) patients; among 69 patients whose overnight EEG recording was obtained, the spike frequency was 35.00 (20.67, 55.00) times/min (0.33-86.33 times/min). (3) Among 120 patients who accepted drug treatment, 87 (72.50%) received monotherapy, including valproic acid ( n=30, 34.48%), oxcarbazepine ( n=21, 24.14%), lacosamide ( n=17, 19.54%), levetiracetam ( n=17, 19.54%), perampanel ( n=1, 1.15%), and lamotrigine ( n=1, 1.15%); 33 (27.50%) received combination therapy with two or more drugs. (4) The comorbid ADHD group had statistically younger age of onset, longer duration of a single episode, higher proportion of seizures both after falling asleep and before awakening, and higher spike wave frequency in EEG than the non-ADHD group ( P<0.05). Conclusions:SeLECTS patients generally have onset age of 3-12 years, seizures within 1 h after falling asleep or 1-2 h before awakening, normal EEG background activity, and epileptiform discharges mostly located in the centrotemporal area, which are different from other types of epilepsy. SeLECTS patients with young age of onset, long duration of a single episode, seizures both after falling asleep and before awakening and high spike wave frequency in EEG trend to develop ADHD comorbidity.
