Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics. There is an urgent need for a precise and adaptable restoration strategy that is more suitable for older individuals. The proposal of a new concept of functional tooth loss updates the minimal restoration standards for elderly patients and establishes the theory of age-friendly functional restoration. Based on the restoration strategy of functional tooth loss, this paper proposes a new concept termed "age-friendly functional restoration of the stomatognathic system", which integrates treatment considerations including endodontics, periodontology, mucosa, muscles, temporomandibular joint, and systemic health. Efforts should be made in four areas as follows. Firstly, the "assessment of accessible function" should be enhanced by considering the interrelationship between stomatognathic and systemic health. Secondly, the "evaluation of appropriate function" is supposed to be optimised in view of subjective needs and objective evaluation of the stomatognathic system. Moreover, the "formulation of treatment plans" needs to be accomplished with the aid of assistive technologies, such as artificial intelligence, to accurately exert appropriate functional restoration. Lastly, the "management and maintenance of health" is likely to be strengthened through follow-ups, propaganda and education, and preventive healthcare, so as to improve quality of life and ultimately achieve healthy ageing among older individuals.

Objective To investigate the effects of two driving pressure-based methods to set positive end-expiratory pressure on pulmonary mechanics and oxygenation in patients undergoing laparoscopic and thoracoscopic esophagectomy.Methods Sixty patients undergoing laparoscopic and thoracoscopic esophagectomy were divided into two groups(n=30 each):incremental group(group Ⅰ)and decremental group(group D).PEEP titration was performed in both groups during thoracoscopy and laparoscopy.Respiratory mechanics parameters,hemodynamic parameters,and blood gas analysis were collected for analysis before preoxygenation(T0),10 minutes after intuba-tion(T1),20 minutes after PEEP application for one-lung ventilation(T2),20 minutes after PEEP application for two-lung ventilation(T3),before extubation(T4),and 30 minutes after extubation(Ts).The postoperative pulmonary complications within 3 days and 7 days after operation,hospitalization duration,and costs were recorded.Results Compared with group Ⅰ,patients in group D showed higher oxygenation index and pulmonary compliance during surgery(P＜0.05).In both groups,driving pressure decreased and compliance increased after PEEP titration(P＜0.05).Conclusion Both driving pressure-guided incremental and decremental titration of individualized PEEP improved intraoperative respiratory mechanics in patients undergoing laparoscopic and thoracoscopic esopha-gectomy,and decremental titration was more effective in improving intraoperative respiratory mechanics and oxygenation in patients during operation.

Objective:To analyze the risk factors for growth disturbance (GD) in children with distal femoral epiphyseal fracture (DFEF) after surgical treatment.Methods:A retrospective study was conducted to analyze the clinical data of the 72 children who had undergone surgery for DFEF at Department of Pediatric Orthopaedics, The Second General Hospital of Fuzhou between February 2013 and February 2024. There were 52 boys and 20 girls with an age of 11.0 (5.0, 13.0) years. The data collected included age at injury, gender, side affected, cause for injury, time from injury to surgery, the maximum fracture displacement, Salter-Harris fracture classification, and presence of high-energy trauma. The risk factors for GD after DFEF surgical treatment were determined through univariate analysis and logistic regression analysis.Results:Distal femur GD occurred in 40.2% (29/72) of the children treated surgically for DFEF. The univariate analysis showed that, compared with the children without GD, those with GD had a significantly significantly longer time from injury to surgery ( P=0.005), a significantly greater fracture displacement ( P=0.002), and more severe Salter-Harris fracture classification ( P=0.045). The logistic analysis showed that all the 3 factors were independent risk factors for GD ( P<0.05). Conclusion:After DFEF surgery, the GD risk is significantly increased by the 3 factors:longer time from injury to surgery, greater fracture displacement, and more severe fracture classification.

Objective:To aralyze the clinical characteristics of Chlamydia pneumoniae infection in Beijing.Methods:Based on Beijing Respiratory Pathogen Surveillance System, acute respiratory infection patients were recruited from 35 different types of sentinel hospitals in Beijing. Their epidemiological and clinical data were systematically collected and clinical specimens were also obtained. Nuclear acid testing was performed for 30 types of respiratory pathogens (including Chlamydia pneumoniae). The identified patients of Chlamydia pneumoniae infection were divided into two groups, the acute upper respiratory tract infection (AURI) group and pneumoniae group. The differences in clinical characteristics, laboratory examination and prognosis were compared by using independent sample t test, Mann-Whitney U test, χ 2 test or Fisher′s exact probability test. Results:A total of 119 patients of Chlamydia pneumoniae infection were included, including 12 patients in the AURI group and 107 patients in pneumoniae group. Chlamydia pneumoniae infection mainly occurred in people aged from 5 to 44 years, accounting for 81.5% (97/119). The three most common clinical symptoms were cough (92.4%, 110/119), fever (88.8%, 95/107), and sputum production (76.5%, 91/119). White blood cell counts increased in 39.3% (46/117) of patients. Neutrophile granulocyte proportion increased in 39.7% (46/116) of patients. Platelet count increased in 36.9% (41/111) of patients. An increase of the creatine kinase MB isoenzyme (CKMB) was observed in 12 pneumonia patients (24.5%, 12/49). Radiological examination showed that 90.6% (87/105) of patients in the pneumoniae group had pulmonary parenchymal changes; the lesion occurred most commonly in the lower right lung lobe (34.3%, 36/105) and the lower left lung lobe (27.6%, 29/105). Although 73.8% (79/107) of patients in the pneumoniae group were hospitalized, no case received intensive care unit or mechanical ventilation. As to outcomes, one patient developed respiratory failure and 6 patients suffered myocardial injury. No death was observed in this study. The median days of hospitalization and course of illness for pneumonia patients M( P25, P75) were 10.0 (7.0, 13.0) days and 18.0 (13.5, 22.0) days, respectively. Conclusion:Generally, Chlamydia pneumoniae infections in Beijing from 2015 to 2019 were mild, and the main clinical manifestations were cough, fever and sputum. However, most patients in the pneumoniae group caused by Chlamydia pneumoniae still required hospitalization but with a better outcome.
