Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

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.

In May 2023, the Chinese Stomatological Association promulgated the group standard of "Clinical Practice Specifications for Permanent Tooth Extraction". These specifications were formulated after repeated discussions and revisions guided by relevant literature and the opinions of well-known experts in the field across the country. However, the content of the group standard is not elaborated and is limited to its writing form and requirements. As a consequence, medical workers might not easily understand and comprehend its content and knowledge points, which also limits its dissemination and wide use in primary medical units. This study aims to sort out and interpret the content of the 2023 edition of the "Clinical Practice Specification for Permanent Tooth Extraction" to help medical staff understand and apply it in clinical practice.

Immature permanent teeth refer to those that have erupted but have not yet formed and matured in terms of shape and structure. The characteristics of their disease onset and treatment methods are different from those of ordinary permanent teeth. Children with special healthcare needs often lack the capacity to cooperate during routine dental procedures, making treatment under general anesthesia (GA) the preferred option. With social advancements, the demand for pediatric dental GA has considerably increased. This study discuss the treatment strategies for immature permanent teeth under GA, including diagnosis, therapeutic principles, key considerations, and clinical approaches for dental caries, pulpitis periapical periodontitis, etc.

Tooth autotransplantation is a restoration technology that grafts the patient's own teeth to the missing tooth area, usually by using the third molar to replace a nonnormally functioning molar for the purpose of "turning waste into treasure". Robotic surgical assistance has been widely used in the fields of breast cancer, liver cancer, and orthopedics; however, its application in the dental field, particularly in tooth autotransplantation, remains relatively rare. This paper reports a case of tooth autotransplantation with the assistance of a domestic autonomous oral surgery robot, providing a reference for the application of robotic surgery assistance in tooth autotransplantation.
