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 clinical efficacy and safety of nivolumab(PD-1 inhibitor)in combination with lenvatinib and FOLFOX regimen[5-fluorouracil(5-FU),oxaliplatin(L-OHP),and calcium folinate(LV)]in the treatment of intermediate and advanced hepatocellular carcinoma(HCC)via hepatic arterial infusion chemotherapy(HAIC).Methods A total of 160 patients with intermediate and advanced HCC admitted to the Second Affiliated Hospital of Guilin Medical University from January 2021 to January 2023 were randomly divided into the control group and the observation group,with 80 patients in each group,using a random number table.The control group received once-daily oral lenvatinib and intravenous carrizumab infusions for 12 weeks as part of transcatheter arterial chemoembolization(TACE)therapy.The observation group was administered with FOLFOX regimen via HAIC chemotherapy,plus intravenous infusion of carrizumab for 12 weeks and once-daily oral lenvatinib.All the patients were followed up regularly.The clinical efficacy was evaluated using the mRECIST criteria.The objective response rate(ORR),disease control rate(DCR),overall survival(OS),progression-free survival(PFS),and incidence of adverse reactions were compared between the two groups.Results There were no significant differences in the objective response rate and incidence of adverse reactions between the groups.The disease control rate,overall survival,and progression-free survival in the observation group were significantly higher than those in the control group(P<0.05).Conclusions The FOLFOX-HAIC regimen in combination with nivolumab and lenvatinib is safe and effective for the treatment of intermediate and advanced HCC,without adverse reactions.It can prolong the overall survival and progression-free survival,and improve the patient's quality of life.

Background and Aims:Postoperative intra-abdominal infection(PIAI)is a common postoperative complication in abdominal surgery and a challenging issue worldwide,with a treatment failure rate of 68.3％and an in-hospital mortality rate as high as 40.8％.The key to managing this condition is early control of the infection source,debridement and adequate drainage.Delayed control of the infection source is an independent risk factor for predicting treatment failure.Many PIAI lesions are located deep within the abdominal cavity,lacking optimal routes for percutaneous drainage,and the risks and difficulties of reoperation are significant.Thus,controlling the infection source in PIAI is a difficult task.Here,the authors report the management of 4 PIAI patients treated with nephroscopic debridement and catheter irrigation and drainage via the sinus tract,aiming to provide clinical insights and references. Methods:The clinical data of 4 patients undergoing nephroscopic debridement,catheter irrigation and drainage for PIAI from October 2020 to September 2022 in the Department of Hepatobiliary and Pancreatic Surgery of the Second Affiliated Hospital of Guilin Medical University were retrospectively analyzed.Key techniques of nephroscopic management of PIAI were summarized and contextualized with relevant literature. Results:The 4 PIAI cases included a right-sided retroperitoneal abscess after catheter drainage for severe acute pancreatitis,a hepatic abscess at the liver raw surface after right hemihepatectomy,bile leakage and secondary duodenal fistula after laparoscopic choledocholithotomy and T-tube drainage,and a pancreatic abscess at the pancreatic raw surface after distal pancreatectomy with splenectomy.All patients underwent nephroscopic debridement and catheter irrigation and drainage via the sinus tract:guidewires were inserted into the drainage sinus tract,followed by a minimally invasive expansion drainage kit and nephroscopy;pus was irrigated out,and pus moss was clamped out with foreign body forceps under nephroscopy.Then,irrigation drainage tubes were placed under the guidance of the guidewire,and continuous irrigation and drainage were performed.The 4 patients underwent a total of 5 nephroscopic debridement and catheter irrigation and drainage procedures,with one case requiring two operations.The preoperative catheterization time ranged from 14 to 58 d,with an average of 38.4 d.One patient concurrently underwent choledochoscopy for stone extraction and biliary drainage via the T-tube sinus tract.The operative time ranged from 30 to 115 min,with an average of 67.4 min.Aside from one case of minor intraoperative bleeding,which stopped after injecting diluted norepinephrine solution into the sheath and blocking the sheath,there were no surgical complications in the other three cases.The postoperative drainage tube duration ranged from 7 to 30 d,with an average of 20.75 d.After treatment,all PIAI lesions disappeared,and no recurrence was observed during follow-up,which ranged from 16 to 40 months. Conclusion:Nephroscopic debridement and catheter irrigation and drainage via the sinus tract for PIAI is simple,feasible,and safe,allowing for direct visualization to avoid organ damage.It is effective in removing pus and necrotic tissue,replacing drainage tubes,and can be repeatedly performed with high efficiency and remarkable results.This method is particularly suitable for patients with postoperative abdominal drainage tube obstruction combined with encapsulated intra-abdominal fluid collections.

Objective:Pediatric chronic sinusitis （CRS） is a common disease within the field of otolaryngology-head and neck surgery. Due to the immaturity of sinus development and immune competence in children, its etiology and pathophysiology are complex, and its clinical features and outcomes differ significantly from those in adult patients. Currently, there are issues in the diagnosis and treatment of pediatric CRS, particularly in areas such as antibiotic use and surgical interventions, owing to a lack of sufficient attention. In recognition of this, the Chinese Rhinopathy Research Cooperation Group developed this expert consensus based on a systematic review of the latest literatures from both domestic and international sources, with reference to the latest evidence-based medical evidence worldwide, and in combination with their own clinical experience. The consensus covers various aspects including epidemiology, predisposing factors, pathophysiology, diagnosis and differential diagnosis, as well as treatment strategies such as medical therapy and surgical intervention. It aims to standardize the clinical diagnosis and treatment of pediatric CRS, improve clinical efficacy and patient satisfaction, reduce clinical expenditures, and decrease the occurrence of adverse reactions.

Periodontitis imparting the increased risk of atherosclerotic cardiovascular diseases is partially due to the immune subversion of the oral pathogen, particularly the Porphyromonas gingivalis (P. gingivalis), by inducing apoptosis. However, it remains obscure whether accumulated apoptotic cells in P. gingivalis-accelerated plaque formation are associated with impaired macrophage clearance. Here, we show that smooth muscle cells (SMCs) have a greater susceptibility to P. gingivalis-induced apoptosis than endothelial cells through TLR2 pathway activation. Meanwhile, large amounts of miR-143/145 in P.gingivalis-infected SMCs are extracellularly released and captured by macrophages. Then, these miR-143/145 are translocated into the nucleus to promote Siglec-G transcription, which represses macrophage efferocytosis. By constructing three genetic mouse models, we further confirm the in vivo roles of TLR2 and miR-143/145 in P. gingivalis-accelerated atherosclerosis. Therapeutically, we develop P.gingivalis-pretreated macrophage membranes to coat metronidazole and anti-Siglec-G antibodies for treating atherosclerosis and periodontitis simultaneously. Our findings extend the knowledge of the mechanism and therapeutic strategy in oral pathogen-associated systemic diseases.

Objective:To evaluate the MRI manifestations of condylar bone regeneration after disc reduction and suture for anterior disc displacement without reduction (ADDWoR) patients and to analyze the relevant factors affecting bone regeneration.Methods:A total of 61 patients of 75 joints with ADDWoR who attended the Department of Maxillofacial Surgery of the Affiliated Hospital of Stomatology of Nanjing Medical University from April 2020 to December 2021 were enrolled in the study. The characteristics of MRI condylar bone regeneration were analyzed before and after surgery (follow-up for 6 months or more), and logistic regression analysis was performed on the influencing factors of bone regeneration.Results:The new bone formation of the condyle was found in 28 patients, with age of (20.2±4.9) years. However, there were 33 patients that had no condylar bone regeneration, with age of (41.9±17.5) years. A total of 35 joints in this study were found new bone formation. There were 16 joints (45.7%) had new bone formation on the posterior slope of the condyle, 10 joints (28.6%) around the condyle, 6 joints (17.1%) on the anterior slope of the condyle, and only 3 joints (8.6%) on the top of the condyle. Multivariate logistic regression analysis showed that age, preoperative disc length and degree of condylar bone resorption correlated with postoperative condylar bone regeneration( P<0.05). Patients younger than 30 years with non-shortened preoperative disc length and less condylar bone resorption have a higher probability of new bone formation. Conclusions:The condyle has bone regeneration capacity after correcting the abnormal relationship between disc and condyle, and young age, non-shortened preoperative disc length and less condylar bone resorption are conducive to postoperative condylar bone regeneration.

Birth cohort study has played an important role in exploring the effect of exposures in early life on long-term health of offspring. With the rapid increase of problems of reproductive health among couples at childbearing age, the assisted reproductive technology (ART) has been widely introduced into clinical practice. However, the influences of ART on long-term outcomes of mothers and infants have not been fully studied. In 2016, the China National Birth Cohort (CNBC), a multicenter prospective cohort study recruiting families with ART-conceived pregnancies and spontaneous-conceived pregnancies simultaneously was launched officially. By June 30, 2021, a total of 72 000 families covering 39 000 ART- pregnancies and 33 000 spontaneous- pregnancies have been recruited in the study, their information and biological samples were collected at multiple time points, i.e., before assisted reproductive treatment, in embryo transfer period, in first, second and third trimesters, at delivery, and at 42 days after birth, 6 months, 1 year old and 3 years old. The main objectives of this study are to assess the development and health of offspring born after ART treatment, identify risk factors associated with adverse birth outcomes and childhood diseases and provide scientific basis for the strategies to improve the quality of new birth population. This paper will give a brief introduction to the establishment and research progress of CNBC.

Objective:To investigate the risk factors of in-hospital mortality in elderly patients with traumatic brain injury (TBI).Methods:A case control study was conducted on 709 elderly patients with TBI admitted to Luhe Hospital, Capital Medical University from January 2012 to October 2018, including 468 males and 241 females; aged 60-97 years [(70.4±8.5)years]. Patients were divided into death group ( n=82) and survival group ( n=627) based on death or not during hospitalization. Data of the two groups were documented, including gender, age, causes of injury (traffic accident injury, fall injury, assault injury or others), history of comorbidities (hypertension, coronary heart disease, diabetes or coronary heart disease), Glasgow coma score (GCS) on admission, operation modalities (trepanation and drainage, hematoma evacuation, decompressive craniectomy or intracranial pressure monitoring), complications (pneumonia, stress ulcer, electrolyte imbalance, hypoproteinemia or secondary epilepsy) and length of hospitalization. Univariate analysis was used to analyze the correlation between the above factors and in-hospital mortality in elderly patients with TBI. Multivariate Logistic regression analysis was used to determine the independent risk factors for their in-hospital mortality. Results:Univariate analysis showed that sex, causes of injury, hypertension, cerebral infarction, diabetes, GCS on admission, hematoma evacuation, decompressive craniectomy, intracranial pressure monitoring, pneumonia, stress ulcer and length of hospital stay were correlated with in-hospital mortality in elderly patients with TBI ( P<0.05 or 0.01), while there was no correlation with age, history of coronary heart disease, trepanation and drainage, electrolyte imbalance, hypoproteinemia and secondary epilepsy (all P>0.05). Multivariate Logistic regression analysis showed that fall injury ( OR=0.28, 95% CI 0.08-0.96, P<0.05), hypertension ( OR=0.29, 95% CI 0.10-0.84, P<0.05),GCS of 9-12 points on admission ( OR=12.98, 95% CI 4.70-35.84, P<0.01), GCS of 3-8 points on admission ( OR=33.67, 95% CI 14.01-80.93, P<0.01) and length of hospital stay<11 days ( OR=0.06, 95% CI 0.02-0.13, P<0.01) were significantly associated with their in-hospital mortality. Conclusions:Fall injury, hypertension, GCS≤12 points on admission and length of hospital stay <11 days are independent risk factors for in-hospital mortality in elderly patients with TBI, especially that patients with GCS of 3-8 points on admission have higher in-hospital modality than patients with GCS≥ 9 points, indicating the importance of above independent risk factors in evaluating outcome.

In China, the survival rate of liver cancer remains low while the mortality rate is high. Effectively reducing the burden of liver cancer is still a major challenge in the field of public health and chronic disease prevention in the Chinese population. Optimizing screening strategies for liver cancer remains a profound approach to secondary prevention worthy of continuous explora-tion. This guideline was commissioned by the Bureau of Disease Control and Prevention of the National Health Commission. The National Cancer Center of China initiated the guideline develop-ment and convened a multidisciplinary expert panel and working group. Following the World Health Organization Handbook for Guideline Development, this guideline integrated the most up-to-date evidence of liver cancer screening, China′s national conditions, and existing practical experience in liver cancer screening. Evidence-based recommendations on the target population, screening technologies, surveillance strategies, and other key points across the process of liver cancer screening and surveillance management were provided. This guideline would help to standardize the practice of liver cancer screening in China.
