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.

Drug therapy is a common method to cure diseases and relieve symptoms.The value of patient-reported outcome(PRO)in evaluating the effect of drug therapy has been increasingly paid attention.The PRO scale is a standardized questionnaire,which can scientifically evaluate the experiences and subjective effects of drug use from a patient-centered perspective,and help patients and clinicians make more reasonable medication decisions.By reviewing and sorting out relevant global literature,this paper found that the content of the PRO scales relevant to drug therapy focused on five fields:"medication satisfaction""medication adherence""drug treatment burden""medication-related quality of life"and"adverse drug reactions".This paper described the basic information,measurement characteristics and application of common scales in recent years respectively,and summarized and analyzed the problems and enlightenment of scale development,aiming to provide theoretical reference for the selection,application and development of PRO scales.

Innate immune response is the first line of immune defense in our body against invaded pathogens.After receive pathogen stimulation,immune cells synthesize abundant type Ⅰ interferons(IFNs)through activating three different signaling path-ways to establish strong antiviral immune response.Mounting evidences have revealed that selective autophagy participates in the regu-lation of innate type Ⅰ IFN response and prevents the excessive activation of immune responses.E3 ubiquitin ligases transfer different type of polyubiquitin chains to some key signaling proteins,and trigger the selective degradation of these proteins through autophago-some-lysosome pathway.Therefore,autophagy and E3 ubiquitin ligases integrate the spatiotemporal regulation of innate type Ⅰ IFN response.In this review,we summarized current data elucidating the critical role of autophagy and E3 ubiquitin ligases in the regula-tion of innate immune response.

Objective:To explore the diagnostic value of laboratory examination in bronchoalveolar lavage fluid(BALF) for interstitial lung disease (ILD) and its application value in assessing the degree of fibrosis in the disease.Methods:Retrospective analysis. The clinical data of ILD patients treated in Shanghai First People′s Hospital from January 1, 2021 to December 31, 2023[104 cases, male︰female=48︰56, (62.79±1.24) years] were collected. According to the imaging scores, they were divided into a mild fibrosis ILD group [53 cases, male︰female=26︰27, (61.32±1.71) years] and a moderate to severe ILD fibrosis group [51 cases, male︰female=22︰29, (64.31±1.88) years]. Patients with community-acquired pneumonia without fibrotic lesions by HRCTduring the same period were selected as the control group [49 cases, male︰female=25︰24, (65.37±1.65)years]. The clinical information of all study subjects, as well as BALF lymphocyte subset analysis, cytokine and cytology count detection results were collected. Furthermore, the Kruskal-Wallis H test was used to screen the differential indexes, and the receiver operating characteristic (ROC) curve was used to evaluate the differential indexes to assess the degree of ILD pulmonary fibrosis.Results:Compared with the non-fibrotic pneumonia group, IL-6, IL-8, CD4+CD45RO+cells and macrophages (M%) were significantly upregulated in the mild fibrosis ILD group (P<0.05), and significantly higher in the moderate to severe fibrosis ILD group ( P<0.05). Compared with the non-fibrotic pneumonia group, IL-1β and white blood cell (WBC) count were significantly upregulated only in the moderate to severe fibrotic ILD group ( P<0.05). The correction model was constructed by stepwise logistic regression analysis, and the differential indexes were combined, and the proportion of IL-1β+IL-6+IL-8+CD4+CD45RO+cells+macrophages was finally screened as the optimal combined diagnostic mode, with an area under the curve of 0.925, sensitivity of 92.3%, and specificity of 80.0%. Conclusion:Compared with the non-fibrotic pneumonia group, BALF-derived IL-1β, IL-6, IL-8, CD4+CD45RO+cells, WBC count and M% can be used as potential biomarkers to assess the degree of fibrosis, and the combination of IL-1β+IL-6+IL-8+CD4+CD45RO+cells+macrophages has a better diagnostic efficacy for moderate to severe fibrotic ILD.

Arsenic is a widely occurring metalloid element in the natural environment and is one of the primary carcinogens identified by the World Health Organization (WHO), but the specific carcinogenic mechanism is currently unclear. In recent years, through toxicological studies on arsenic, it has been found that exposure to arsenic can affect cellular metabolism in the body, which may be closely related to the carcinogenic mechanism of arsenic. Therefore, the authors review the research progress on arsenic exposure-induced effects on glucose metabolism, lipid metabolism, and amino acid metabolism, with a view to providing a theoretical basis for the study of the mechanism of arsenic carcinogenesis.

Objective To observe the effects of postoperative complications, anal exhaust time, immune function and fatigue index of parenteral and enteral nutrition support after abdominal surgery in elderly patients with malnutrition diagnosed by GLIM criteria. Methods Ninty elderly abdominal surgery patients (more than 70 years old) who diagnosed as malnutrition by GLIM 2-step method were divided into enteral nutrition(EN) group and parenteral nutrition (PN) group randomly. The corresponding immune and fatigue indexes were tested on day 1 and day 7 of postoperation. Postoperative complications, anal exhaust time and mean time of hospitalization were observed and analyzed. Results The incidence of malnutritional risk was 61.0% (122/200) in elderly abdominal surgery patients and malnutrition incidence was 45.0% (90/200). IgA, IgM, IgG, CD3, CD4 and CD4/CD8 on postoperative day 7 increased significantly in EN group than those in PN group (P<0.05). The postoperative complications in EN group significantly lower than that in PN group (P<0.05). Anus exhaust time and hospitalization days of EN group were shorter than that of PN group (P<0.05). Fatigue index on postoperative day 7 of EN group was significantly better than that of PN group (P<0.05). Conclusions The malnutrition diagnosis of elderly patients based on GLIM crteria is a necessary prerequisite for nutritional intervention. Early EN support can reduce postoperative complications and hospitalization days in elderly patients, improve postoperative fatigue syndrome and immune status, and improve the patients with malnutrition recover from surgery.

Conclusion The expression of serum exosomal miR⁃30d-5p decreases in OMDT patients , which is negatively correlated with the level of liver function , and the target gene RHOB may be involved in the process of liver injury induced by trichloroethylene.

Objective:To investigate the clinical value of computer tomography (CT)-based three-section formula in identification of Siewert types of adenocarcinoma of esophagogastric junction (AEG).Methods:The retrospective and descriptive study was conducted. The clinicopatho-logical data of 62 AEG patients who were admitted to two medical centers, including 33 patients from Peking University Cancer Hospital and 29 patients from the First Affiliated Hospital of Amy Medical University, between January 2019 and January 2021 were collected. There were 53 males and 9 females, aged (66±9)years. All patients underwent CT examination to obtain the coronal and axial images and determine the upper and lower edges of the tumor and the esophagogastric junction, which were imported into the formula for Siewert classification. Observation indicators: (1) results of CT examination and pathological examination; (2) consistence of judgements for CT examination between doctors; (3) consistence of judgements between CT examination and patholo-gical examination. Results of pathological examination came from intraoperative surgical observa-tion and postoperative histopathological examination. Measurement data with normal distribution were represented as Mean± SD, and count data were described as absolute numbers or percentages. The consistency coefficient Kappa ( κ) was used to evaluate the consistency of diagnosis between resear-chers. The κ≥0.75 was regarded as excellent consistency, 0.40< κ<0.75 as good consistency, κ ≤0.40 as poor consistency. Wilcoxon rank sum test was used to evaluate the statistical difference between results of the CT-based three-section formula method and the pathological examination. Taking the results of histopathological examination as standard, the sensitivity, specifi-city, accuracy and 95% confidence interval of the CT-based three-section formula method were calculated. Results:(1) Results of CT examination and pathological examination: all the 62 patients underwent CT examination successfully to obtain the coronal and axial images and determine the upper and lower edges of the tumor and the esophagogastric junction, which were used for Siewert classifica-tion. There were 3 cases with AEG of Siewert type Ⅰ, 47 cases with AEG of Siewert type Ⅱ and 12 cases with AEG of Siewert type Ⅲ according to doctor's judgement from the Peking University Cancer Hospital, and there were 3 cases with AEG of Siewert type Ⅰ, 49 cases with AEG of Siewert type Ⅱ and 10 cases with AEG of Siewert type Ⅲ according to doctor's judgement from the First Affiliated Hospital of Amy Medical University, respectively. After arbitration, there were 2 cases with AEG of Siewert type Ⅰ, 48 cases with AEG of Siewert type Ⅱ and 12 cases with AEG of Siewert type Ⅲ determined by the CT based three-section formula. There were 7 cases of stage T1, 10 cases of stage T2, 24 cases of stage T3, 14 of stage T4a and 7 cases of stage T4b of pathological T staging. There were 2 cases with AEG of Siewert type Ⅰ, 48 cases with AEG of Siewert type Ⅱ and 12 cases with AEG of Siewert type Ⅲ determined by pathological examination. (2) Consistence of judgements for CT examination between doctors: the consistency of Siewert classification determined by CT-based three-section formula between 2 doctors was good ( κ=0.74, P<0.001). (3) Consistence of judgements between pathological examination and CT examination: with Siewert classification determined by pathological examination as reference, the accuracy of Siewert classification determined by CT based three-section formula was 90.3%( κ=0.73, P<0.001). The sensitivity and specificity of CT-based three-section formula were 66.7%(95% confidence interval as 20.8%-93.9%) and 100.0%(95% confidence interval as 93.9%-100.0%) for AEG of Siewert type Ⅰ, 97.7%(95% confidence interval as 88.2%-99.6%) and 72.2%(95% confidence interval as 49.1%-87.5%) for AEG of Siewert type Ⅱ, 73.3%(95% confidence interval as 48.0%-89.1%) and 97.9%(95% confidence interval as 88.9%-99.9%) for AEG of Siewert type Ⅲ, respectively. Conclusion:The CT-based three-section formula can be used for identification of Siewert types of AEG, with a high accuracy.
