ObjectiveTo investigate the status of tooth loss in people aged 50 and above, so as to understand their oral health status and provide scientific evidences for promoting oral health of middle-aged and elderly people. MethodsA total of 400 patients who visited the department of stomatology at Sijing Hospital in Songjiang District of Shanghai were performed oral health examinations and their information was collected according to the national epidemiological survey standards for oral health. ResultsThere were statistically significant differences in tooth loss among people aged 50 and above with different ages, educational levels, occupations, types of medical insurance and chronic diseases (P<0.05), but gender and monthly income had no statistically significant correlations with tooth loss (P>0.05). Among lifestyle factors, smoking, alcohol consumption and tea drinking had no statistically significant impacts on the number of remaining teeth (P>0.05), but toothbrushing frequency, flossing frequency, toothpick use frequency, toothbrush replacement frequency, and tooth loosening were statistically associated with the number of remaining teeth (P<0.05). Multiple linear regression analyses indicated that a total of 7 related factors including age, educational level, occupation, medical payment type, chronic disease, tooth loosening and toothpick use frequency were significantly associated with the number level of remaining teeth in individuals aged 50 and above. ConclusionAge, chronic disease, and tooth loosening were influencing factors affecting the number of teeth left in people aged 50 and above. It is recommended to strengthen oral health education and improve healthcare awareness to reduce the risk of tooth loss in people aged 50 and above.

Objective To investigate the impact of type 2 inflammation markers blood eosinophils(EOS)and fractional exhaled nitric oxide(FeNO)on bronchodilator responsiveness(BDR)in patients with chronic obstructive pulmonary disease(COPD).Methods This study was conducted among 389 patients with an established diagnosis of COPD in our hospital from October,2019 to October,2023,who all underwent bronchial dilation test(BDT)of the large and small airways.Based on smoking history,blood EOS,and FeNO,these patients were divided group A(blood EOS<300/μL+FeNO<35 ppb+smoking history<20 pack-years),group B(blood EOS<300/μL+FeNO<35 ppb+smoking history≥20 pack-years),group C(blood EOS≥300/μL or FeNO≥35 ppb+smoking history≥20 pack-years),and group D(blood EOS≥300/μL or FeNO≥35 ppb+smoking history<20 pack-years)for analyzing the relationship between clinical indexes and BDR.Results BDR evaluation based on forced expiratory volume in 1 second(FEV1),forced vital capacity(FVC),and maximum mid-expiratory flow(MMEF)yielded consistent results,all showing a younger mean age,higher FeNO levels,and higher blood EOS counts and percentages in patients positive for BDT(P<0.05).The improvement value and improvement rate of FEV1 were significantly lower in group A than in group D.The improvement value and improvement rate of FEV1 as well as the improvement rate of MMEF were significantly lower in group B than in group D.In the overall patients,age and FeNO were significantly correlated with the improvement value and improvement rate of FEV1 and the improvement rate of MMEF(P<0.05).Conclusion Type 2 inflammation markers have different effects on BDR in the large and small airways of COPD patients,and their clinical significance needs further investigation.

Objective:To summarize the content and effects of exercise interventions for stroke survivors, providing references for medical and nursing personnel in formulating exercise intervention plans for these patients.Methods:Literature on exercise interventions for stroke survivors was searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, China Biology Medicine disc, Cochrane Library, PubMed, Embase, and Web of Science up to May 1, 2023. Data extraction and summarization were conducted on the included literature.Results:Twenty-two articles were included in the review. The exercise types for stroke survivors primarily involved aerobic and resistance training; the intensity was mainly moderate to high; the frequency was mostly 3-5 times per week, with each session lasting 30-60 minutes; and the duration of interventions ranged from as short as two weeks to as long as one year. Exercise interventions improved stroke survivors' functional mobility, quality of life, cardiopulmonary function, mental state, cognitive function, fatigue, sleep, and compliance to varying degrees.Conclusions:Exercise interventions have achieved positive outcomes in stroke survivors. In the future, medical and nursing personnel can incorporate patient preferences into exercise intervention plans while ensuring patient safety to promote rehabilitation.

Objective To use superparamagnetic iron oxide nanoparticles(SPIONs)to label chimeric antigen receptor(CAR)T cells targeting carcinoembryonic antigen(CEA),and perform magnetic resonance imaging(MRI)to real time trace CEA CAR-T cells in vivo.Methods Appropriate amount of ferumoxytol,heparin sodium and protamine sulfate were mixed at high(ferumoxytol 100 μg/mL,heparin sodium 4 IU/mL,protamine sulfate 120 μg/mL),medium(ferumoxytol 50 μg/mL,heparin sodium 2 IU/mL,protamine sulfate 60 μg/mL),and low(ferumoxytol 25 μg/mL,heparin sodium 1 IU/mL,protamine sulfate 30 μg/mL)concentrations to form a SPIONs complex ferumoxytol/heparin/protamine(FHP),and then co-incubated with CEA CAR-T cells for cell labeling.The biocompatibility of FHP was detected by CCK-8 assay,EdU assay and flow cytometry.The uptake of FHP was detected by Prussian blue staining,and SPIONs content in the cells was quantitatively detected by inductively coupled plasma-mass spectrometry(ICP-MS).Flow cytometry was used to detect the lytic effect of FHP-labeled CEA CAR-T cells on tumor cells,and MRI was employed to scan FHP-labeled CEA CAR-T cells.Results FHP at high,medium,and low concentrations had no significant effect on the activity of CEA CAR-T cells,with cell activity above 100％determined by CCK-8 assay.DNA proliferation was above 94.3％in EdU assays.Prussian blue staining showed that CEA CAR-T cells could take FHP up,with the uptake increased with the increment of FHP concentration.ICP-MS showed that the intracellular Fe content was 440.23±189.36 ng/mL.Tumor cell killing experiment showed that FHP-labeled CEA CAR-T cells had excellent killing capability against tumor cells.MRI scans indicated that T2WI signals of FHP-labeled CEA CAR-T cells were significantly reduced with increasing FHP concentration(P＜0.01).Conclusion SPIONs complex FHP shows good biocompatibility and can effectively label CEA CAR-T cells.SPIONs complex FHP can be used as a magnetic marker for CEA CAR-T cells and a feasible MRI tracer for clinical application.

Objective:To conduct an overview of systematic reviews on the safety and effectiveness of early mobilization in stroke patients.Methods:Systematic reviews of early mobilization in stroke were electronically searched on China National Knowledge Infrastructure, WanFang Data, VIP, Chinese Biology Medicine, Cochrane Library, PubMed, Web of Science, CINAHL, Embase, and the Joanna Briggs Institute Evidence-Based Health Care Center Database. The search period was from database establishment to May 2023. Two researchers independently conducted literature screening, data extraction, and methodological quality evaluation of the included literature, as well as evidence summary and grading.Results:A total of 10 systematic reviews were included. The methodological quality evaluation showed that one article was of medium quality, two articles were of low quality, and seven articles were of extremely low quality. The evidence quality evaluation indicated that there were three pieces of high-quality evidence, 17 pieces of medium-quality evidence, 21 pieces of low-quality evidence, and 17 pieces of extremely low-quality evidence.Conclusions:Early mobilization is beneficial for improving the daily living ability and limb motor function of stroke patients, reducing the incidence of complications, shortening hospital stay, and enhancing their walking ability in the short term. However, the quality of evidence in the systematic review is relatively low, and further improvement is needed in the research design of early mobilization intervention measures to provide strong support for clinical practice.

Objective To investigate the current status and influencing factors of physical activity (PA) among stroke survivors. Methods A total of 203 stroke survivors were selected as the research subjects using convenient sampling method. General information questionnaire, Stroke Self-efficacy Scale, Perceived Social Support Scale, Modified Rankin Scale, International Physical Activity Questionnaire-Long Form, Fatigue Severity Scale, and European Five-Dimension Health Scale were used for questionnaire survey. Based on the health ecological model, hierarchical multiple linear regression analysis was used to explore the influencing factors of PA among stroke survivors. Results Using metabolic equivalents (MET) to quantify energy expenditure, the weekly PA energy expenditure of 203 stroke survivors was 693.0 (0, 1 386.0) MET. The results of hierarchical multiple linear regression analysis showed that personal traits (stroke staging), behavioral characteristics and psychology (Modified Rankin Scale score, fatigue severity, stroke recovery self-efficacy), and interpersonal networks (perceived social support-friend support dimension) were the main influencing factors of PA among stroke survivors (P < 0.05), which could explain 55.5% of the variation in PA. Conclusion The level of PA among stroke survivors is influenced by multi-dimensional and multi-level complex factors in their health ecosystem, and it is currently at a low level. Healthcare professionals can formulate comprehensive strategies to improve PA among stroke survivors based on the health ecological model, aiming to further enhance the PA level of stroke survivors and promote physical function recovery.

OBJECTIVE: To investigate the prevalence of vitamin D deficiency and its association with blood eosinophil count in healthy population and patients with chronic obstructive pulmonary disease (COPD). METHODS: We analyzed the data of a total 6163 healthy individuals undergoing routine physical examination in our hospital between October, 2017 and December, 2021, who were divided according to their serum 25(OH)D level into severe vitamin D deficiency group (< 10 ng/mL), deficiency group (< 20 ng/mL), insufficient group (< 30 ng/mL) and normal group (≥30 ng/mL). We also retrospectively collected the data of 67 COPD patients admitted in our department from April and June, 2021, with 67 healthy individuals undergoing physical examination in the same period as the control group. Routine blood test results, body mass index (BMI) and other parameters were obtained from all the subjects, and logistic regression models were used to investigate the association between 25(OH)D levels and eosinophil count. RESULTS: The overall abnormal rate of 25(OH)D level (< 30 ng/mL) in the healthy individuals was 85.31%, and the rate was significantly higher in women (89.29%) than in men. Serum 25(OH)D levels in June, July, and August were significantly higher than those in December, January, and February. In the healthy individuals, blood eosinophil counts were the lowest in severe 25(OH)D deficiency group, followed by the deficiency group and insufficient group, and were the highest in the normal group (P < 0.05). Multivariable regression analysis showed that an older age, a higher BMI, and elevated vitamin D levels were all risk factors for elevated blood eosinophils in the healthy individuals. The patients with COPD had lower serum 25(OH)D levels than the healthy individuals (19.66±7.87 vs 26.39±9.28 ng/mL) and a significantly higher abnormal rate of serum 25(OH)D (91% vs 71%; P < 0.05). A reduced serum 25(OH)D level was a risk factor for COPD. Blood eosinophils, sex and BMI were not significantly correlated with serum 25(OH)D level in patients with COPD. CONCLUSION Vitamin D deficiency is common in both healthy individuals and COPD patients, and the correlations of vitamin D level with sex, BMI and blood eosinophils differ obviously between healthy individuals and COPD patients.

Objective:To analyze the compliance with enhanced recovery after surgery (ERAS) protocol in geriatric patients with fresh fracture.Methods:A retrospective study was conducted on the data of the patients with fresh extremity fracture which had been included in the ERAS perioperative protocol database during May 2019 and January 2022 at Department of Orthopaedic Trauma, Beijing Jishuitan Hospital. The patients ≥65 years were selected as a study group which was matched by a control group of the patients < 65 years in sex, fracture type and date frame of hospitalization at a ratio of 1∶1. The 2 groups were compared in the compliance with the 14 ERAS core perioperative elements.Results:The study group and the control group each included 66 patients who were matched in sex and fracture type. 62.1% (41/66) of the patients in the study group had combined diseases, significantly more than that [16.7% (11/66)] in the control group( P<0.001). Altogether, the compliance with the 14 ERAS core perioperative elements was 78.6 (71.4, 85.7) % in both groups, showing no significant difference between them ( P>0.05). Respectively, the compliance with the postoperative oral intake in the study group (80.3%, 53/66) was significantly lower than that in the control group (92.4%, 61/66) ( P<0.05); the compliance with the other 13 elements showed no statistically significant difference between the 2 groups ( P>0.05). Conclusion:The ERAS perioperative protocol can be carried out smoothly in geriatric patients with fresh fracture whose compliance may be comparable to that of the none-elderly patients.

Objective To explore the effect of proprioceptive neuromuscular facilitation (PNF) rehabilitation training on functional recovery of athletic rotator cuff injury. Methods Twenty-two college students with athletic rotator cuff injuries were stratified according to their gender and randomly divided into resistance band + passive joint range of motion (ROM) training group (control group) and PNF training group (experimental group). The visual analog scale (VAS) was used to evaluate subjective pain intensity of the shoulder joint. Pain positive rate for each manipulation test of rotator cuff injury was observed, and active ROM and muscle strength of the shoulder joint were measured. Improved UCLA shoulder joint score was used to evaluate comprehensive function of the shoulder joint. Results After training, VAS scores and pain positive rate in two groups were lower than those before training, and VAS scores and pain positive rate in experimental group were lower than those in control group. Muscle strength, active ROM in all directions and improved UCLA score of the shoulder joint in two groups were also higher than those before training, and the internal rotation muscle strength, the internal rotation and external rotation active ROM, improved UCLA score of the shoulder joint in experimental group were higher than those in control group. Conclusions PNF rehabilitation training can reduce the pain of athletic rotator cuff injury, improve the active ROM, muscle strength and UCLA shoulder joint score. The function recovery effect of PNF training is better than that of resistance band + passive ROM training.
