Objective To explore the characteristics of gastric emptying in the whole process of drinking water for colonoscopy in the elderly,and to develop an elderly-friendly drinking water program,thereby improving the comfort and the quality of bowel preparation.Methods From April to September 2024,gastric ultrasound was used to monitor gastric emptying indicators in the whole process of drinking water for colonoscopy in the elderly,summa-rizing its physiological features.On this basis,in October 2024,through literature review and expert argumentation,a bowel preparation drinking water program that meets the characteristics of gastric emptying in the elderly was de-veloped.A convenience sample of 90 elderly patients scheduled for colonoscopy at 2 tertiary hospitals in Beijing was enrolled from November 2024 to January 2025.A non-concurrent controlled trial was conducted:an experimen-tal group from December 2024 to January 2025 received the new elderly-friendly drinking water program,while a control group in November 2024 followed the conventional program.Outcomes included drinking comfort assessed via Visual Analogue Scale(VAS),adverse events,total fluid intake volume and bowel preparation quality via Boston Bowel Preparation Scale(BBPS).Results The experimental group demonstrated superior VAS score(P＜0.05),bowel preparation quality(P＜0.05),total fluid intake(P＜0.05),and higher compliance with optimal stool consistency(P＜0.05),compared to the control group.The experimental group also exhibited a lower incidence of adverse events(P＜0.05).No significant difference was observed in total bowel preparation duration between 2 groups(P＞0.05).Conclusion The bowel preparation drinking water program based on the characteristics of gastric emptying in the elderly improved solution intake tolerance and bowel preparation quality,with practical implications for clinical implementation.

The early symptoms of chronic obstructive pulmonary disease(COPD)are insidious,and its occurrence and development are a gradual accumulation of pathogenic factors.Clinically,it exhibits symptoms of yang deficiency and yin injury,and its pathogenic characteristics are consistent with the insidious,accumulative and injury positive characteristics of the latent cold."Latent cold"runs through the entire course of COPD.Qi-yang deficiency is the basis for the production of latent cold,external cold triggers the onset of latent cold and the cohesion of latent cold is the key to its onset.The clinical practice advocates for staged treatment based on clinical manifestations and the characteristics of changes in latent cold.During the acute phase of the attack,external cold invasion occurs and there is excessive movement due to the presence of cold.Treatment is based on warming and promoting the spread of pathogenic factors;during chronic stable period,warming and supplementing qi yang should be adopted;during the gradual aggravation period,the patients are prone to prolong chilliness and stagnation with phlegm and blood stasis forming.The treatment is based on a combination of warming and cooling.

Objective:To investigate the current status of fear of falling in postoperative cardiac surgery patients, and to analyze its influencing factors and interrelationships.Methods:A convenience sample of 246 postoperative cardiac surgery patients hospitalized in the Department of Cardiac Surgery, the First Affiliated Hospital of Xiamen University, from December 2023 to December 2024 was surveyed. The Body Image Scale, the Personal Mastery Scale, the Fear of Falling Questionnaire-Revised, and a self-designed demographic and clinical questionnaire were used for data collection. Pearson correlation analysis was conducted to examine the relationships among body image, personal mastery, and fear of falling. PROCESS Model 4 was applied to test the mediating role of personal mastery between body image and fear of falling, with bootstrapping for verification.Results:A total of 246 questionnaires were distributed, and 236 valid responses were obtained (valid response rate: 95.93%) . The body image score was (14.02±6.36) , personal mastery score was (20.44±4.16) , and fear of falling score was (38.28±10.83) . Body image was positively correlated with fear of falling ( r=0.324, P<0.01) , while personal mastery was negatively correlated with fear of falling ( r=-0.552, P<0.01) . After controlling for variables with statistically significant differences in univariate analysis (including sex, age, education level, body mass index, history of syncope, pain level, and self-rated preoperative exercise capacity) , PROCESS analysis showed that body image had a direct positive effect on fear of falling ( β=0.288, P<0.05) , and also indirectly affected fear of falling through personal mastery, with the indirect effect accounting for 49.5% of the total effect (0.237/0.525) . Conclusions:Postoperative cardiac surgery patients require improvement in body image, personal mastery, and fear of falling. Understanding how body image influences fear of falling through personal mastery not only enriches theoretical frameworks but also provides guidance for psychological interventions in clinical practice, thereby meeting patients' psychological support needs during rehabilitation.

Objective:To systematically evaluate the efficacy and safety of nirsevimab in preventing respiratory syncytial virus (RSV) infection in infants.Methods:Randomized controlled trials (RCTs) of nirsevimab in the prevention of RSV infection in newborns and infants (≤ 2 years old) were collected by searching relevant databases at home and abroad (up to February 12, 2025). Subjects in the trial group received a single dose injection of nirsevimab, while those in the control group received placebo or no interventions, with an observation period of ≥150 days. The efficacy outcome indicators included the incidence of acute lower respiratory tract infections (LRTI), RSV-associated hospital visits, RSV-associated hospitalization, and severe RSV infection events. The safety outcome indicators were the occurrence of adverse events (AEs) after injection of nirsevimab. Quality of methodology was evaluated using bias risk assessment tool of Cochrane collaboration networks. Meta-analysis was performed using RevMan 5.4 software. The effect sizes were relative risk ( RR) and its 95% confidence interval ( CI). Results:A total of 4 RCTs and 11 051 subjects were entered in the analysis, including 6 032 subjects in the trial group and 5 019 in the control group. The results of meta-analysis showed that compared with the control group, the incidences of acute LRTI [4.94% (298/6 032) vs. 5.70% (286/5 019), RR=0.57, 95% CI: 0.41-0.81], RSV-associated hospital visits [1.85% (37/1 995) vs. 7.11% (71/998), RR=0.26, 95% CI: 0.18-0.38], RSV-associated hospitalization [0.31% (19/6 032) vs. 1.75% (88/5 019), RR=0.17, 95% CI: 0.07-0.43], and severe RSV infection events [0.10% (5/5 038) vs. 1.52% (69/4 523), RR=0.07, 95% CI: 0.03-0.17] in the trial group were significantly lower, and the differences were statistically significant (all P<0.001). The differences in incidences of AEs, grade ≥3 AEs, AEs of great concern, and death events in the 2 groups during the observation period were not significant (all P>0.05), and no nirsevimab-related death events occurred. Conclusion:Nirsevimab is effective in preventing RSV infection in infants and has a good safety profile.

Objective To explore the clinical efficacy and safety of salbutamol sulfate combined with reduced glutathione in treating acute exacerbation of chronic obstructive pulmonary disease(COPD)in the elderly.Methods A total of 103 elderly patients with acute exacerbation of COPD who were admitted to the Qingpu Branch of Zhongshan Hospital,Fudan University from January 2020 to June 2022 were randomly assigned to three groups.Control group 1(34 cases)received nebulized normal saline treatment.Control group 2(34 cases)received conventional treatment(e.g.,oxygen therapy,anti-infection,expectorant therapy,etc.)plus reduced glutathione.Treatment group(35 cases)received additional salbutamol sulfate on the basis of the control group 2.The treatment course was 12 days.Lung function,inflammatory factors,COPD assessment test,(CAT)score,BODE index,cardiopulmonary oxygenation function,6-minute walk test(6MWT)distance,modified medical research council dyspnea scale(mMRC)score,St.George's respiratory questionnaire(SGRQ)score,acute exacerbation frequency within 2 years,and adverse reactions were recorded.Results After treatment,the forced expiratory volume in 1 second(FEV1),forced vital capacity(FVC),and FEV1/FVC ratio in the treatment group were significantly higher than those in the control groups,while procalcitonin(PCT)and C-reactive protein(CRP)levels in the treatment group were significantly lower than those in the control groups(P<0.05).The treatment group exhibited lower CAT scores and BODE indices,higher maximal oxygen uptake(VO2max),metabolic equivalent of task at peak exercise(METspk),and respiratory frequency at peak exercise(RFEspk),longer 6MWT distances,and lower mMRC and SGRQ scores as compared with the control groups(P<0.05).The frequency of acute exacerbation in the treatment group was lower than that in the control groups at 6 months,1 year,and 2 years after treatment(P<0.05).No significant differences in adverse reactions were observed among the three groups(P>0.05).Conclusion The combination of salbutamol sulfate and reduced glutathione can significantly improve lung function,reduce inflammation,enhance quality of life,decrease acute exacerbation frequency,and demonstrate good safety in elderly patients with acute exacerbation of COPD.

Objective:To explore the relationship between dietary pattern and sexual function in people of childbearing age.Methods:This study adopted a cross-sectional method and included all women and men who visited Reproduction Center of Maanshan Maternal and Child Health Hospital, Reproductive Medicine Center of the 901th Hospital of the Joint Logistics Support Force of People's Liberation Army and Reproduction Center of Anhui Wanbei Coal Power Group General Hospital from December 2020 to March 2022. The Female Sexual Function Index (FSFI) and International Index of Erectile Function-15 (IIEF-15) were used to assess sexual function. Factor analysis was used to establish dietary patterns, and multivariate logistic regression was used to analyze the association between dietary patterns and sexual function.Results:A total of 1 290 females and 1 331 males were included in the study, including 1 031 females and 899 males with sexual dysfunction. There were 289 women and 272 men with balanced dietary pattern, 473 women and 395 men with traditional dietary pattern, 272 women and 324 men with processed dietary pattern, and 256 women and 340 men with beverage dietary pattern. After adjusting for confounding factors such as residence and age, it was found that balanced dietary pattern was negatively correated with female sexual desire disorder ( OR=0.904, 95% CI: 0.820-0.995, P=0.039), sexual arousal disorder ( OR=0.840, 95% CI: 0.759-0.929, P=0.001), vaginal lubrication disorder ( OR=0.833, 95% CI: 0.710-0.979, P=0.026), orgasmic disorder ( OR=0.764, 95% CI: 0.680-0.858, P<0.001), low sexual satisfaction ( OR=0.887, 95% CI: 0.796-0.987, P=0.028), sexual dysfunction ( OR=0.805, 95% CI: 0.714-0.907, P<0.001), and male orgasmic disorder ( OR=0.859, 95% CI: 0.763-0.967, P=0.012). The traditional dietary pattern was negatively correlated with female sexual desire disorder ( OR=0.879, 95% CI: 0.786-0.983, P=0.024), sexual arousal disorder ( OR=0.884, 95% CI: 0.784-0.995, P=0.042), male erectile disorder ( OR=0.736, 95% CI: 0.634-0.855, P<0.001), sexual desire disorder ( OR=0.753, 95% CI: 0.648-0.876, P<0.001), and sexual dysfunction ( OR=0.769, 95% CI: 0.653-0.907, P=0.020). The processed dietary pattern was positively correlated with erectile disorder ( OR=1.162, 95% CI: 1.049-1.287, P=0.004), orgasmic dysfunction ( OR=1.207, 95% CI: 1.091-1.337, P<0.001), sexual desire disorder ( OR=1.199, 95% CI: 1.081-1.330, P=0.001) and sexual dysfunction ( OR=1.134, 95% CI: 1.020-1.261, P=0.002). Beverage dietary pattern was not associated with sexual dysfunction in men and women (all P>0.05). Conclusion:Balanced, traditional dietary patterns were related to the reduce risk of sexual dysfunction in both women and men of childbearing age, while processed dietary patterns were related to the increased risk of sexual dysfunction in men of childbearing age.
