With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

Objective: To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children. Methods: Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model. Results: Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats. Conclusions Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.

Objective: To compare the biological characteristics of human induced pluripotent stem cell-derived platelet exosomes (hiPSC-Plt-Exos) with those of conventional apheresis platelet exosomes (Plt-Exos), specifically focusing on their differential abilities to enhance the proliferation and migration of human umbilical cord mesenchymal stem cells (hUC-MSCs). Methods: Exosomes were isolated from hiPSC-derived Plt and apheresis Plt concentrate using size exclusion chromatography. These exosomes were then characterized through nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), and Western blotting. Co-culture experiments into hUC-MSCs were conducted with hiPSC-Plt-Exos and apheresis Plt-Exos, respectively. Their effects on the proliferation and migration of hUC-MSCs were assessed via cell proliferation assays and scratch tests. Results: hiPSC-Plt-Exos and apheresis Plt-Exos exhibited comparable particle sizes, morphological features (such as the characteristic cup-shaped structure), and surface markers (including CD9 and HSP70). Notably, hiPSC-Plt-Exos demonstrated a significantly greater ability to enhance the proliferation and migration of hUC-MSCs compared to apheresis Plt-Exos (P<0.05). These differences provide critical comparative data for their application in various clinical contexts. Conclusion: This study establishes a theoretical foundation for developing precise therapeutic strategies based on hiPSC-Plt-Exos. Furthermore, it underscores the necessity of selecting the appropriate type of exosomes according to the specific disease microenvironment to achieve optimal therapeutic outcomes.

Objective To evaluate the relationship between anxiety levels and clinicopathological characteristics in patients with papillary thyroid carcinoma (PTC). Methods Among the patients who underwent surgical treatment in our center from July 2022 to September 2023, 304 patients completed the Hamilton anxiety rating scale (HAM-A) questionnaire. The clinical and pathological characteristics of these patients and their association with anxiety levels were investigated. Results Among the 304 patients, 271 were pathologically confirmed to have PTC. Of the 271 patients, 75 had higher levels of anxiety (according to HAM-A scoring system, a score ≥14 indicates clinically significant anxiety) and were assigned to the anxiety group. Univariate statistical analysis showed that the proportion of patients with elevated thyroid peroxidase antibody (TPOAb) in the anxiety group was higher than that in the non-anxiety group (34.7% vs. 16.8%, P=0.002 4). Moreover, the proportion of patients with multifocal tumors in the anxiety group was also higher than that in the non-anxiety group (33.3% vs. 16.7%, P=0.004 4). Multivariate Logistic regression confirmed that anxiety levels were associated with elevated TPOAb (P=0.005 6) and tumor multifocality (P=0.001 9). Conclusions Anxiety levels may be related to elevated TPOAb and tumor multifocality in PTC patients.

Objective To compare the filtration effects of different models of leukocyte filters on erythrocyte suspensions,so as to provide a reference for the selection of leukocyte filters in clinic.Methods The erythrocyte suspensions prepared by Department of Blood Transfusion of The First Affiliated Hospital of Naval Medical University were used for filtration.The test was categorized into three groups based on the model of leukocyte filters,namely,AKTT-type(group Ⅰ),STTB-type(group Ⅱ),and STTA-type(groupⅢ).Each group was randomly assigned 8 bags of erythrocyte suspensions(specification 2U)with hematocrit≤55%and 10 bags of erythrocyte suspensions(specification 2U)with hematocrit>55%,and leukapheresis was applied.The quality indexes of the blood were detected before and after filtration,and the experimental data were comprehensively analyzed to evaluate the leukocyte filtration effect of various filters.Results When the hematocrit of the filtered erythrocyte suspensions was≤55%,there were significant differences in the platelet count after filtration(F=49.94,P<0.001)and filtration time(F=73.45,P<0.001)between groups,and the two indexes in group Ⅰ were superior to those in groups Ⅱ and Ⅲ.When the hematocrit of the filtered erythrocyte suspensions was>55%,there were significant differences in the platelet count after filtration(F=160.69,P<0.000 1),filtration time(F=366.09,P<0.000 1),residual leukocytes(F=4.28,P<0.05),and hemolytic rate(F=8.16,P<0.01)between groups.The platelet count after filtration and filtration time in group I were superior to those in group II and III.The indexes of residual leukocyte and hemolytic rate in groups I and II were superior to those in group III.Conclusion In order to ensure the safety and effectiveness of erythrocyte suspension transfusion,AKTT-type filter can be chosen to perform leukocyte filtration,which can further lower the blood transfusion complications.

Objective To understand the current status and influencing factors of patient perception for humanistic care in China hospitals,and to provide a basis for developing nursing humanistic care measures and improving the quality of nursing humanistic care services.Methods A total of 30,099 outpatients and inpatients from 107 hospitals in 30 provinces(autonomous regions and municipalities)from July to August 2022 as survey subjects.A general information questionnaire and the Relational Caring Questionnaire-Patient Form were used for a cross-sectional survey,and a single-factor analysis was used to analyze the influencing factors of patient relationship care.Results Finally,29 108 valid questionnaires were collected,and the effective questionnaire recovery rate was 96.7％.The patient evaluation of relationship care was(65.72±8.61)points.Single-factor analysis showed that gender,age,marital status,children's situation,education level,occupation,place of residence,average family income,medical insurance type,visiting department,and location of the visiting hospital,and whether or not surgery were influencing factors of patient relationship care(P＜0.05).Conclusion The evaluation score of caregiver-patient relationship care among Chinese hospital patients is above average,but there is still room for improvement in western and rural regions,seriously ill and outpatient patients,low-income and low-medical insurance reimbursement populations,and non-surgical patients.Medical institutions at all levels should optimize and improve nursing humanistic care services based on influencing factors,and further enhance patients'perception of nursing humanistic care.

Host immune response to viruses is critical for virus clearance and disease control. Dramatically decreased numbers and exhaustion of immune cells are common in COVID-19 patients, which is found to be closely related to the severity of the disease and poor prognosis. Human leukocyte antigen G (HLA-G) is an important immune checkpoint that can specifically bind to various immunosuppressive receptors expressed by immune cells, and systematically suppress the host immune response. Recent studies have shown that HLA-G gene polymorphism and its expression are of great significance for susceptibility to SARS-CoV-2 and the progression of COVID-19. In this review, the genetic and molecular characteristics of HLA-G, HLA-G/receptor signaling and immune function regulation, and its clinical significance in COVID-19 progression are summarized.

The goal of Medical Immunology is to enable students to pay attention to integration of immunology theory with clini-cal practice,be familiar with professional English,consciously pay attention to cutting-edge knowledge,and can learn independently and lifelong.However,existing teaching models lack explanation of clinical disease related events,and arrangement of experimental content and projects is seriously disconnected from clinical practice,scientific research on solving clinical problems is clearly insuffi-cient.We established a"B to B"cycle model for immunology teaching by starting from clinical practical problems(Bedside),return to basic research(Bench),and then solve clinical problem(Bedside),which will comprehensively cultivate senior medical profession-als with clinical competence,scientific research thinking ability,innovative spirit,and international perspective.
