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.

Objective:Induced pluripotent stem cells (iPSCs) cell lines were established using peripheral blood mononuclear cells (PBMCs) from a patient suffering from neonatal respiratory distress syndrome (NRDS) who carried Adenosine triphosphate-binding cassette transporter A3 ( ABCA3) compound heterozygous mutations. Methods:Cell experimental research.Peripheral venous blood was collected and PBMCs were isolated and cultured in vitro. PBMCs were transfected with non-integrated Sendai vector carrying reprogramming factors.The chromosome karyotypes of the established iPSCs were analyzed.Immunofluorescence and flow cytometry were used to detect pluripotency markers of stem cells and verify their differentiation potential.Sanger sequencing was performed to analyze gene mutations.In addition, short tandem repeat (STR) analysis was performed, polymerase chain reaction(PCR) and agarose gel electrophoresis were used to detect virus residual. Results:Karyotype analysis of established iPSCs cell lines showed normal diploid 46, XY karyotype.Immunofluorescence showed positive staining of stem cell pluripotency markers OCT4, SSEA4, Nanog and Sox2.Flow cytometry was used to detected stem cell pluripotency markers and showed expression of TRA-1-60, SSEA-4 and OCT4.After differentiation into all three germ layers, immunofluorescence was performed to detect ectoderm (Pax-6), mesoderm (Brachyury) and endoderm alpha-fetoprotein markers, and the results showed positive staining, which confirmed that the iPSCs had the potential to differentiate.Sanger sequencing showed c. 3997_3998del and c. 3137C>T compound heterozygous mutations.STR analysis showed they originate from PBMCs, and no Sendai virus residual was detected by PCR and agarose gel electrophoresis.Conclusions:In this study, PBMCs from patient carrying ABCA3 compound heterozygous mutations was used to establish iPSCs cell lines.The research lays a foundation for the study of pathogenesis, therapeutic drug screening and cell therapy of NRDS caused by ABCA3 gene mutations.

[Objective]To explore the etiology,pathogenesis and clinical treatment of histiocytic necrotizing lymphadenitis(HNL)based on the insidious pathogen warm disease theory.[Methods]To analyze the etiology,pathogenesis,characteristics of symptoms and transmission of the disease in Chinese medicine,and summarize the treatment principles based on the descriptions about insidious pathogen warm disease in ancient literature and modern researches on HNL,and cite a clinical case for verification.[Results]The pathogenesis of the HNL is mainly characterized by deficient healthy Qi leading to latent evil.The specific manifestation is that exogenous evils are latent in the Moyuan,which causes Yang Qi to be blocked and depressed and turns into heat.Evil heat spreads from the Moyuan to the Shaoyang tri-Jiao,leading to the generation of phlegm,static blood,turbid evil and toxin in the body,which in turn leads to disease.In terms of treatment,supporting healthy Qi and eliminating the evil is regarded as the law of treatment,and the emphasis is eliminating the evil.Aiming at the three pathogenetic links of latent evil,depressed heat and internal production of pathological products,the following treatment principles are formulated:expelling evils from Moyuan,dredging tri-Jiao and promoting the flow of Qi to make the evil heat go out,clearing away endogenous pathological products,removing toxin and dispersing knots.The focus of supporting healthy Qi is the protection of Qi and Yin as well as recuperation after recovery,which prevents evil Qi from remaining and causing the disease to reoccur.The medical case cited was a patient with HNL treated by applying the theory of insidious pathogen warm disease.Damp-heat and toxin brewing,phlegm combined with static blood was the traditional Chinese medicine(TCM)pattern of this case.The the prescriptions were based on Shengjiang Powder combined with Sanren Decoction,and Ganlu Xiaodu Pill successively,added and subtracted according to the syndrome,and the case achieved a significant effect.[Conclusion]The effect of treating HNL based on the insidious pathogen warm disease theory is quite good,which can provide new ideas and methods for the diagnosis and treatment of HNL.

Genome-wide association studies (GWASs) are the most widely used method to identify genetic risk loci associated with orofacial clefts (OFC). However, despite the increasing size of cohort, GWASs are still insufficient to detect all the heritability, suggesting there are more associations under the current stringent statistical threshold. In this study, we obtained an integrated epigenomic dataset based on the chromatin conformation of a human oral epithelial cell line (HIOEC) using RNA-seq, ATAC-seq, H3K27ac ChIP-seq, and DLO Hi-C. Presumably, this epigenomic dataset could reveal the missing functional variants located in the oral epithelial cell active enhancers/promoters along with their risk target genes, despite relatively less-stringent statistical association with OFC. Taken a non-syndromic cleft palate only (NSCPO) GWAS data of the Chinese Han population as an example, 3664 SNPs that cannot reach the strict significance threshold were subjected to this functional identification pipeline. In total, 254 potential risk SNPs residing in active cis-regulatory elements interacting with 1 718 promoters of oral epithelium-expressed genes were screened. Gapped k-mer machine learning based on enhancers interacting with epithelium-expressed genes along with in vivo and in vitro reporter assays were employed as functional validation. Among all the potential SNPs, we chose and confirmed that the risk alleles of rs560789 and rs174570 reduced the epithelial-specific enhancer activity by preventing the binding of transcription factors related to epithelial development. In summary, we established chromatin conformation datasets of human oral epithelial cells and provided a framework for testing and understanding how regulatory variants impart risk for clefts.

It is an important measure to establish an effective communication mechanism for filling in the front page of medical records to ensure the good operation of diagnosis-related groups. Taking cerebral infarction as an example, the authors carried out the pilot work of multidisciplinary cooperation mode based on disease types around its coding axis. The multi-disciplinary assistance model could provide a good platform for communication and learning among multiple disciplines, break the barriers between disciplines, improve the quality of the front page and medical record writing of clinicians, and improve the quality and efficiency of coders′ coding.

BACKGROUNDOveractive bladder (OAB) is a series of symptoms with high prevalence in elderly people. This study was conducted using the overactive bladder symptom score (OABSS) to evaluate the efficacy of solifenacin succinate for the treatment of OAB.

METHODSThis was a prospective, multicenter, single-arm, 12-week study that enrolled 241 OAB patients. The patients received 5-10 mg/day solifenacin. Changes in OABSS, symptoms from voiding diary, perception of bladder condition (PPBC) score, international prostate symptom score (IPSS) and quality of life (QOL) were evaluated at weeks 0, 4, and 12. The relationship between OABSS and PPBC score or parameters of voiding diary was also evaluated.

RESULTSAt baseline, the mean OABSS for all patients was 9.41 ± 2.40, and was reduced significantly at week 12 (-3.76 points; 61.21%, P < 0.0001). The OABSS subscore, PPBC score, IPSS, and QOL were also significantly reduced during the study (P < 0.0001). The overall incidence of adverse events was 19.91% (44 cases). The gastrointestinal system was the most commonly affected (11.31%). Around 5.88% of the cases had adverse events related to the genitourinary system. There was a strong correlation between OABSS and urinary symptoms that was recorded in the 3-day voiding dairy.

CONCLUSIONSWe showed that solifenacin was clinically effective for relieving OAB symptoms, considering the balance between efficacy, patients' well-being, and tolerability. OABSS integrates four OAB symptoms into a single score and can be a useful tool for research and clinical practice.
