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 investigate the key genetic mutations during the progressive disease (PD) /leukemic transformation (LT) course in MDS by analyzing the dynamic changes of genetic mutations in patients with myelodysplastic neoplasms (MDS) with or without PD/LT.Methods:This study enrolled 84 patients with sequential MDS from May 2019 to August 2023 at ZhongDa Hospital Southeast University and used the next generation sequencing to detect gene mutations. The dynamic changes of genetic mutations in patients with MDS with or without PD/LT were retrospectively analyzed.Results:①This study analyzed data from 84 patients diagnosed with MDS with a median age of 63 (range: 31-95) years and consisting of 51 males and 33 females. Participants were distributed to the PD cohort ( n=20), LT cohort ( n=13), and non-PD/LT cohort ( n=51). Patients from the PD/LT cohorts demonstrated a higher proportion of bone marrow blasts than the non-PD/LT cohort at the first sequencing (1.6% vs. 0.4%, P=0.013). ②The most frequently mutated genes that were detected at first sequencing were ASXL1 ( n=21, 25.0%), TP53 ( n=17, 20.2%), TET2 ( n=12, 14.3%), DNMT3A ( n=11, 13.1%), and U2AF1 ( n=11, 13.1%). Further, patients from the PD/LT cohorts exhibited a higher median number of mutated genes than the non-PD/LT cohort (2 vs.1, P=0.014) at first sequencing. TET2 (27.3% vs. 5.9%, P=0.010), SETBP1 (15.2% vs.2.0%, P=0.033), and RUNX1 (18.2% vs. 2.0%, P=0.013) mutations were enriched in the PD/LT cohorts than in the non-PD/LT cohort. ③The most frequently detected acquired mutations (Ⅰ mutations) and clonally expanded mutations (Ⅱ mutations) were TP53 ( n=9, 10.7%), TET2 ( n=7, 8.3%), ASXL1 ( n=7, 8.3%), and RAS pathway ( n=7, 8.3%). Furthermore, patients from the PD/LT cohorts showed a higher median number of Ⅰ/Ⅱ genes than the non-PD/LT cohort (2 vs. 0, P<0.001), and Ⅰ/Ⅱ RAS pathway (21.2% vs. 0, P=0.001), TP53 (27.3% vs. 0, P<0.001), and TET2 (18.2% vs. 2.0%, P=0.013) mutations were enriched in PD/LT cohorts than in the non-PD/LT cohorts. ④Most of the TP53 mutations (9/12, 75.0%) in PD/LT cohorts were Ⅰ/Ⅱ mutations, whereas all of the TP53 mutations in non-PD/LT cohort were clone-decrease mutations (Ⅲ mutations) (5/8, 62.5%) or clone-stable mutations (Ⅳ mutations) (3/8, 37.5%). Most of the RAS pathway mutations (7/8,87.5%) in the PD/LT cohorts were Ⅰ/Ⅱ mutations, whereas only one patient in the non-PD/LT cohort demonstrated RAS pathway mutations, which belonged to Ⅳ mutations. Conclusion:Patients from the PD/LT cohorts demonstrated a higher proportion of bone marrow blasts and a higher median number of mutations than the non-PD/LT cohort at first sequencing; TET2, SETBP1, and RUNX1 mutations were enriched in the PD/LT cohorts than in the non-PD/LT cohort at first sequencing. Patients from the PD/LT cohorts exhibited a higher number of Ⅰ/Ⅱ mutations than the non-PD/LT cohort. Further, Ⅰ/Ⅱ TP53, RAS pathway, and TET2 mutations were enriched in the PD/LT cohorts, and Ⅰ/Ⅱ TP53 and RAS pathway mutations may contribute to the PD/LT.

Artificial intelligence(AI)is reconstructing drug quality control systems with unprecedented depth.With the rapid development of the traditional Chinese medicine(TCM)industry,the quality regulation of TCM has garnered increasing attention.The efficacy and safety of TCM directly impact public health,making it imperative to enhance the scientific rigor and effectiveness of its quality control.In recent years,the application of AI technology has expanded across various fields,and its potential in TCM quality regulation has gradually been recognized.Cur-rently,AI has demonstrated advantages in multiple stages of TCM production,including cultivation and planting,authenticity identification of decoction pieces,compliance review of manufacturing processes,market circulation monitoring,and risk assessment.However,despite existing research achievements,challenges such as limited technological adoption,low standardization,and insufficient data sharing persist.This paper provides an in-depth review of innovative AI applications in TCM quality control,comprehensively analyzes their effectiveness and future prospects,and proposes a novel"AI-Digital Sensory-Blockchain"tri-synergistic quality control paradigm based on domestic and international research advancements.Furthermore,it explores potential future research directions to advance the modernization of TCM quality regulation,thereby achieving higher levels of safety assurance and scien-tifically robust supervision.

To implement the instructions and directives of General Secretary Xi Jinping on important documents related to traditional Chinese medicine （TCM）， adhere to the equal emphasis on TCM and Western medicine， and promote mutual complementarity， win-win cooperation， and coordinated development between TCM and Western medicine， the China Association of Chinese Medicine has organized seminars on the clinical dominant diseases of TCM in multiple professional fields， achieving a series of results. The aim is to implement the research on dominant diseases of TCM described in the Law of the People's Republic of China on Traditional Chinese Medicine and the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance， Innovation and Development of Traditional Chinese Medicine， thus serving the construction of advantageous specialties， clinical talent cultivation， national scientific and technological layout， and academic innovation leadership. In the field of otolaryngology， the China Association of Chinese Medicine and many Chinese and Western medicine experts across the country have conducted multiple in-depth discussions and research. At the 10^th Clinical Dominant Disease Series Youth Salon， they have elaborated and demonstrated the basic and specific suggestions and consensus on the clinical advantages of TCM and integrated TCM and Western medicine in the treatment of allergic rhinitis （AR）， making great progress. However， there is still a lack of detailed research paths. Under the guidance of the China Association of Chinese Medicine and based on the TCM Dominant Disease Series Salon for AR， this study analyzed the difficulties encountered in AR diagnosis and treatment according to the occurrence and development law of AR. Based on the advantages and characteristics of AR diagnosis and treatment by TCM and integrated TCM and Western medicine， it explored the research paradigm and technological layout points of AR and put forward suggestions. The layout involved four aspects： Optimization of the AR diagnosis and treatment system， prevention and control of comorbidities， management of chronic diseases， and a platform for TCM inheritance. Additionally， suggestions for layout and research directions， expected goals and values， and priority levels for funding were proposed. The study is expected to provide a theoretical basis and development ideas for the future prevention and treatment of AR with TCM and integrated TCM and Western medicine and promote the high-quality development of TCM.

Occlusal rehabilitation is an effective means of treating tooth wear, edentulous jaws and other oral diseases. Among them, full-mouth fixed occlusal reconstruction can effectively restore aesthetics and function, but the complexity of the clinical process, the high sensitivity of the technique, and the high incidence of various complications have always drawn much attention. With the application and development of digital technology in occlusal rehabilitation, the treatment outcome has been improved compared with traditional treatment. However, there are many kinds of digital technology with different efficacy, how to build an efficiently standardized digital clinical technical solution is a current difficulty. Therefore, combined with the long-term work of the department of prosthodontics in our hospital, in this paper, the minimum (occlusal perception of thickness) and maximum (centric relation) geometric quantities which should be paid attention to during reconstruction are put forward. We systematically organized the clinical procedure of digital full-mouth fixed occlusal rehabilitation used in our department for a long time. In conclusion, a 5-stage 19-step or n-step solution (5-19N for short) characterized by "from large to small" restorative space splitting logic is proposed. It has a certain reference value for the future use of digital technology to deal with complex occlusal rehabilitation cases.

Objective:To evaluate the outcomes of intensive conservative treatment compared to conventional conservative treatment in patients with acute aortic syndrome(AAS).Methods:The study prospectively enrolled consecutive patients with AAS who were admitted to Beijing Anzhen Hospital, affiliated with Capital Medical University, and Beijing Dawanglu Emergency Rescue Hospital from January 2024 to December 2024. These patients with surgical contraindications or refused surgery for various reasons opted for conservative treatment. A total of 282 patients were included, and 15 patients with missing data or those who died without any treatment were excluded. Finally, 267 patients were enrolled, of whom 94 received intensive conservative treatment, and 173 received conventional conservative treatment, the inverse probability of treatment weighting (IPTW) was used to reduce the influence of confoundings. After adjusting of baseline datas via IPTW, the survival outcomes of the two groups were compared at 14 days, 30 days, and at the end of follow-up.Results:The results showed significant differences in acute phase survival rates between the enhanced conservative treatment group and the conventional conservative treatment group at 14 days(82.40%vs.53.20%, P<0.0001). Significant survival differences were also observed at 30 days and at 276-day mid-term follow-up (96.29% vs.51.60%, P<0.0001; 78.50% vs.48.50%, P<0.0001). In the subgroup analysis, for type A aortic dissection, the enhanced conservative treatment group had higher survival rates compared to the conventional conservative treatment group at 14, 30 and 276 days (63.46% vs.41.35%, P<0.05; 52.17% vs.37.90%, P<0.05; 50.00% vs. 31.97%, P<0.05). However, for type B aortic dissection, although the enhanced conservative treatment group had higher survival rates than the conventional conservative treatment group, no statistically significant differences were observed (96.29% vs. 80.00%, P=0.054; 95.65% vs.78.37%, P=0.067; 94.12% vs.74.20%, P=0.088). Conclusion:For patients diagnosed with AAS are forced to choose conservative treatment if emergency surgery is not possible in the first place, intensive conservative treatment strategies can significantly reduce the mortality in the acute phase compared with conventional conservative treatment. Mid-term follow-up, intensive conservative treatment still has a significant survival advantage.

Objective:To investigate the clinical characteristics of cervical adenocarcinoma and analyze the survival status and related prognostic factors.Methods:The data of 229 patients with cervical adenocarcinoma who were diagnosed pathologically in the General Hospital of Ningxia Medical University from January 2013 to October 2022 were retrospectively analyzed. Among them, 198 early stage patients were mainly treated with surgery, and 31 locally advanced stage patients were mainly treated with chemoradiotherapy. The overall survival (OS) and progression-free survival (PFS) rates in the whole cohort of patients and different treatment subgroups were calculated. Kaplan‐Meier method and log‐rank test were used for survival analysis, and Cox proportional hazards model was used for univariate and multivariate survival analyses.Results:Among the 229 patients, there were 11 subtypes of pathological classifications, predominantly of the usual‐type. At the end of follow‐up, 57 patients (24.9%) relapsed. The 3‐ and 5‐year OS rates were 86.4% and 79.3%, respectively, and the 3‐ and 5‐year PFS rates were 81.6% and 73.6%, respectively. Multivariate analysis showed that International Federation of Gynecology and Obstetrics (FIGO) staging of stages Ⅲ‐Ⅳ was an independent prognostic factor for OS and PFS ( HR=2.033, 95% CI=1.456‐2.839, P<0.001; HR=1.701, 95% CI=1.251‐2.313, P=0.001). Lymph node metastasis was an independent risk factor for PFS ( HR=1.610,95% CI=1.021‐2.539, P=0.041). Subgroup analysis of 198 patients with surgical treatment: the 3‐ and 5‐year OS rates were 90.0% and 84.9%, and the 3‐ and 5‐year PFS rates were 82.7% and 76.7%, respectively. Multivariate analysis showed that lymph node metastasis and deep invasion depth were the main risk factors for OS ( HR=6.893, 95% CI=2.592‐18.327, P<0.001; HR=1.952, 95% CI=1.164‐3.272, P=0.011) and PFS ( HR=5.507, 95% CI=2.569‐11.805, P<0.001; HR=1.638, 95% CI=1.09‐2.461, P=0.018). Ovarian preservation was an independent risk factor for PFS ( HR=3.364, 95% CI=1.115‐10.151, P=0.031). Conclusions:The pathological types of cervical adenocarcinoma are complex and diverse. Local recurrence and distant metastasis are the main reasons for treatment failure. FIGO stage, lymph node metastasis and postoperative depth of invasion are the main prognostic factors of cervical adenocarcinoma.

Objective:To investigate the feasibility of segmented total marrow and lymphoid irradiation(TMLI)using Helical TomoTherapy(HT)in adults,and to analyze the impact of positional errors in the treatment on the actually received dose.Methods:Imaging data from four adult patients with acute myeloid leukemia were treated at the First Medical Center of the Chinese PLA General Hospital between November 2022 and December 2024 were retrospectively selected.The prescribed dose was 12 Gy in 3 fractions,and the heights range of patient was from 162 to 178 cm.The planning target volume(PTV)included the entire bone marrow and lymphatic drainage regions.The mid-femur was used as the dividing landmark,and the segmented location of head-in first(upper segmentation)and foot-in first(lower segmentation)were adopted to design plan for each segmentation.The upper segmentation used helical tomotherapy,and the lower segmentation used tomo direct therapy.The dosimetric parameters of planning target volume,and organ at risk(OAR)included eye lens,testicles and lungs were analyzed.The located computed tomography(CT)images of patients were used to simulate the changes of dosimetric parameters of each planning target region and OAR when the positions of patients moved 3,5,10 and 15 mm to outside of rack aperture.The changes of dose distribution of connection region of upper and lower segmentation were further analyzed.Results:The segmented irradiation technique can better achieve the cover(95%)of whole target region of TMLI under the condition of protecting normal organs.Under the condition with different position errors,the cover rate of the most of target region significant decreased.The largest dose of right lens increased 9.272%than primary under the 5 mm position error,and that of left and right lens increased respectively 40.199%and 67.898%under the 10 mm position error,and the max dose and mean dose of testicles increased respectively 5.847%and 5.240%under the 3mm position error.The mean dose of whole lung increased all under the error at different grades,which increased 3.021%under the 10mm position error.The non-uniformity of dose distribution of connection region increased after the position error was introduced,and the largest variation range reached to 4 Gy.Conclusion:The technique of segmented radiotherapy of Helical Tomotherapy has feasibility for TMLI of adult.But the error of the position of patients can reduce the cover of target region,and decrease the control rate for target region,and can lead to the occurrences of excessive doses on eye lens,testicles,lung and other OAR at the same time,which can increase the probability of occurring OAR injury.It should be high pay attention in treatment and implementation.
