With a growing public emphasis on oral health, efficacy-focused toothpastes have become mainstream. By combining chemical active ingredients with mechanical cleaning, these products deliver multifunctional benefits, such as caries prevention, dentin hypersensitivity relief, whitening, and anti-inflammation. This article systematically reviews recent advances in key efficacious ingredients across four functional domains: fluoride, often supplemented with calcium-phosphorus compounds, probiotics, and herbal preparations, primarily prevents caries; antibacterial and anti-inflammatory effects arise from multi-ingredient synergy; anti-hypersensitivity works via physical occlusion and nerve inhibition, with herbal extracts as natural alternatives; and whitening involves mechanical abrasion, chemical action, and optical modification. However, current research remains fragmented and repetitive, lacking a systematic evidence base. This complicates evidence-based consumer choice, while studies on precision and personalized formulations are still limited. Future efforts should establish comprehensive efficacy evaluation systems, investigate multi-component synergies, and advance precision toothpaste development tailored to individual oral microbiomes and needs. By summarizing ingredients, mechanisms, efficacy, and safety elements, this review aims to support optimized toothpaste formulation and clinical application, thereby contributing to oral healthcare precision.

Objective:To evaluate the short-term outcomes of robotic double-flap technique following proximal gastrectomy in patients with carcinoma of esophagogastric junction(AEG).Methods:Clinical data of 5 AEG cases undergoing robotic double-flap technique following proximal gastrectomy were analyzed at the Department of Gastrointestinal Surgery, Peking University First Hospital from Dec 2023 to Aug 2024 .Results:All the 5 patients were of Siewert Ⅱ type AEG. Robot-assisted radical proximal gastrectomy and esophagogastric double-flap anastomosis were successfully completed. The operation time was (361±63) min, the installation time was (21±11) min, the anastomosis time was (90±21) min, and the median intraoperative blood loss was 100 (50,200) ml. The median number of intraoperative lymph nodes resected was 23 (14,32), the first postoperative exhaust time was (4.8±1.1) d, and postoperative hospital stay was (14.6±8.8) d. Postoperative abdominal distension occurred in 1 patient, and no significant anastomotic stenosis or anastomotic leakage was observed by upper gastroenterography. After conservative treatment, the patient recovered. None of them had Clavien-Dindo grade ≥Ⅲ complications. There were no anastomotic complications such as anastomotic leakage, anastomotic hemorrhage and anastomotic stenosis.Conclusion:Robotic double-flap technique following proximal gastrectomy is a safe and effective treatment for AEG.

Gene regulation relies on the precise binding of transcription factors (TFs) at regulatory elements, but simultaneously detecting hundreds of TFs on chromatin is challenging. We developed cFOOT-seq, a cytosine deaminase-based TF footprinting assay, for high-resolution, quantitative genome-wide assessment of TF binding in both open and closed chromatin regions, even with small cell numbers. By utilizing the dsDNA deaminase SsdAtox, cFOOT-seq converts accessible cytosines to uracil while preserving genomic integrity, making it compatible with techniques like ATAC-seq for sensitive and cost-effective detection of TF occupancy at the single-molecule and single-cell level. Our approach enables the delineation of TF footprints, quantification of occupancy, and examination of chromatin influences on TF binding. Notably, cFOOT-seq, combined with FootTrack analysis, enables de novo prediction of TF binding sites and tracking of TF occupancy dynamics. We demonstrate its application in capturing cell type-specific TFs, analyzing TF dynamics during reprogramming, and revealing TF dependencies on chromatin remodelers. Overall, cFOOT-seq represents a robust approach for investigating the genome-wide dynamics of TF occupancy and elucidating the cis-regulatory architecture underlying gene regulation.

At present, the incidence and mortality of tumors are increasing, and the treatment of tumors has attracted much attention. Radiotherapy is a key method for tumor treatment; however, its effectiveness is often constrained by radioresistance. During tumor radiotherapy, DNA damage response (DDR) is a key factor in the radioresistance of tumor cells. Research has shown that the radiosensitivity of tumor cells can be effectively improved by regulating the expression of key proteins in the DDR pathway. Targeting the DDR signaling pathway has become an effective strategy to reduce tumor radioresistance. This article focuses on the mechanisms, clinical research status, limitations, and current challenges associated with the key DDR proteins DNA-PKcs, ATM, ATR, and PARP as therapeutic targets for tumor radiotherapy sensitization, in order to provide a reference for the development of radiotherapy sensitization agents.

Objective To analyze the status of occupational disease hazards in Shantou City for 2019 to 2022 and propose corresponding management measures. Methods Technical reports on various occupational-disease-specific activities in Shantou City from 2019 to 2022 were collected and the data were comprehensively analyzed. Results Among the 3 066 enterprises surveyed in the 2020 occupational disease hazard investigation in Shantou City, occupational hazards were reported in 2 982 enterprises (accounting for 97.3%), with 2 955 being small and micro enterprises, accounted for 99.1%(2 955/2 982). The exposure rate of occupational hazards was 58.7% (42 894/73 054) among workers in the surveyed enterprises, with dust and noise exposure rates of 59.7% and 77.8%, respectively. The reported rate of occupational disease hazard projects by employers, regular detection rate of workplace occupational hazards, detection rate of occupational medical examination among workers, and occupational health training rate of key responsible personnel and occupational health management staff were 8.4%, 1.4%, 2.4%, and 4.3%, respectively. The results of occupational hazards monitoring of workplace in key industries from 2019 to 2022 showed that noise had the highest rate of exceeding national standards workplace, followed by silica dust, accounting for 34.2% and 13.8%, with the on-site exceedance rate of 32.2% and 10.0%, respectively. From 2019 to 2022, 31 suspected occupational disease cases were identified in key occupational disease monitoring, including 27 suspected cases of occupational pneumoconiosis and four suspected cases of occupational noise-induced deafness. Conclusion The workers in Shantou City have a high exposure rate to occupational hazards, and the occupational health management level of employers remains low, with noise and silica dust being the most severe occupational hazards. It is essential to improve technical support and service system development for occupational disease prevention and treatment, strengthen supervision and management in key industries and positions, explore occupational health assistance mechanisms for small and micro enterprises, and enforce employers' responsibility in occupational disease prevention to protect workers' occupational health and safety.

Objective To evaluate the potential risk of transmission of angiostrongyliasis by common freshwater snails in Dali Bai Autonomous Prefecture, Yunnan Province, so as to provide insights into local surveillance of angiostrongyliasis. Methods Common freshwater snails were collected from Dali Bai Autonomous Prefecture, Yunnan Province from March to April, 2020, and identified and bred in laboratory. SD rats were infected with third-stage larvae of Angiostrongylus cantonensis that were isolated from commercially available Pomacea canaliculata snails in Dali Bai Autonomous Prefecture, and freshwater snails were infected with the first-stage larvae of A. cantonensis that were isolated from the feces of SD rats 39 days post-infection at room temperature. The developmental process and morphological characteristics of worms in hosts were observed, and the percentages of A. cantonensis infections in different species of freshwater snails were calculated. Then, SD rats were infected with the third-stage larvae of A. cantonensis that were isolated from A. cantonensis-infected freshwater snails, and the larval development and reproduction was observed. Results More than 3 000 freshwater snail samples were collected from farmlands, ditches and wetlands around Erhai Lake in Dali Bai Autonomous Prefecture, and Cipangopaludina chinensis, P. canaliculata, Parafossarulus striatulus, Oncomelania hupensis robertsoni, Galba pervia, Physa acuta, Radix swinhoei, Assiminea spp., Tricula spp. and Bellamya spp. were morphologically identified. A total of 105 commercially available P. canaliculata snails were tested for A. cantonensis infections, and 2 P. canaliculata snails were found to be infected with A. cantonensis, in which the third-stage larvae of A. cantonensis were isolated. Ten species of freshwater snails were artificially infected with the third-stage larvae of A. cantonensis, and all 10 species of freshwater snails were found to be infected with A. cantonensis, with the highest positive rate of A. cantonensis infections in Bellamya spp. (62.3%, 137/204), and the lowest in C. chinensis (35.5%, 11/31). After SD rats were infected with the third-stage larvae of A. cantonensis isolated from different species of freshwater snails, mature adult worms of A. cantonensis were yielded. Conclusions Multiple species of freshwater snails may serve as intermediate hosts of A. cantonensis under laboratory conditions in Dali Bai Autonomous Prefecture of Yunnan Province. Further investigations on natural infection of A. cantonensis in wild snails in Dali Bai Autonomous Prefecture seem justified.

Objective:To provide a basis for its diagnosis and treatment for clinicians by analyzing the clinical manifestations, imaging features and surgical efficacy of primary intraspinal paraganglioma.Methods:The clinical data of 6 patients with intraspinal paraganglioma from April 2014 to January 2021 in Xiangyang Central Hospital were retrospectively analyzed, and all patients were treated with microsurgery via a posterior median approach.Results:All 6 patients achieved total tumor resection, and the postoperative pathological diagnosis was paraganglioma. Among them, 1 patient′s tumor located inside and outside the cervical spinal canal without destruction of the vertebral body; 1 patient′s tumor located lumbosacral canal with destruction of the vertebral body; the others 4 patients′ tumor located within the lumbar spinal canal. The patients were followed up for 12 to 120 months after surgery, with a median follow-up time of 61.5 months. MRI examination was performed at the last follow-up, and no recurrence was observed. The patients underwent MRI examination at the last follow-up, and none of the patients recurred.Conclusions:The intraspinal paraganglioma is a rare tumor, and nonfunctional benign tumors are predominant. Its clinical and imaging manifestations lack specificity and are often difficult to diagnose before surgery. Surgical resection, especially complete resection, has a better prognosis, and the effectiveness of adjuvant therapy is uncertain.
