BACKGROUND:The decreased postural control ability due to mild cognitive impairment in elderly people leads to the increased risk of falls.Dual-task is the primary research paradigm for evaluating the relationship between cognition and postural control in the scenes close to real life.The sample entropy of the plantar center of pressure(COP)displacement during standing can represent the complexity of postural control. OBJECTIVE:Based on the COP displacement sample entropy,to analyze the differences in postural stability characteristics and control strategies between older adults with mild cognitive impairment and cognitively normal older adults during the dual-task with postural control and spatial working memory,aiming to explore the impact of cognitive impairment on the postural control ability during standing. METHODS:Sixteen older adults with mild cognitive impairment and 17 cognitively normal older adults were eligible and selected for the study.They completed five test tasks,including spatial working memory,double-feet balance stance,Romberg stance,double-feet balance stance-spatial working memory dual-task,and Romberg stance-spatial working memory dual-task,with three valid completions of each task.The plantar COP data were collected by the Kistler 3D force platform.The indicators included cognitive behavior(cognitive score and reaction time)and kinematic indexes(COP displacement and sample entropy). RESULTS AND CONCLUSION:The older adults with mild cognitive impairment performed the spatial working memory task with the greatest cognitive score and the shortest reaction time,the double-feet balance stance-spatial working memory dual-task with moderate cognitive score and reaction time,and the Romberg stance-spatial working memory dual-task with the smallest cognitive score and the longest reaction time,where the differences were significant among the tasks(P<0.05).In the older adults with mild cognitive impairment,the anterior-posterior and medial-lateral COP displacements were significantly greater,and their sample entropy values were significantly smaller in the double-feet balance stance-spatial working memory dual-task and Romberg stance-spatial working memory dual-task than in the double-feet balance stance and Romberg stance tasks(P<0.05).In the spatial working memory task,there were no significant differences in cognitive score and reaction time between the both groups(P>0.05);however,in the double-feet balance stance-spatial working memory dual-task and Romberg stance-spatial working memory dual-task,cognitive scores were significantly smaller and reaction times were longer in the older adults with mild cognitive impairment compared with the cognitively normal older adults(P<0.05).In the double-feet balance stance-spatial working memory dual-task and Romberg stance-spatial working memory dual-task,the older adults with mild cognitive impairment exhibited significantly greater anterior-posterior and medial-lateral COP displacements and significantly smaller sample entropy values compared with the cognitively normal older adults(P<0.05).All findings indicate that compared with cognitively normal older adults,older adults with mild cognitive impairment exhibit smaller complexity,poorer systematic adaption and decreased automatic regulation of the postural control during performing the dual-tasks,who are more susceptible to spatial working memory interference,leading to the increased risk of falls.

Objective To study the spatial distribution of the incidence of pulmonary tuberculosis in Hubei Province and its influencing factors, so as to improve the theoretical basis for scientific development of tuberculosis prevention and control measures in the future. Methods The data of reported incidence of tuberculosis and related influencing factors in various counties and districts of Hubei Province in 2020 were collected. Global Moran's I index, hotspot analysis and geographically weighted regression (GWR) model analysis were used to calculate the spatial autocorrelation of the incidence of tuberculosis, and to analyze the influencing factors affecting the incidence rate of tuberculosis. Results There were obvious regional differences in the space distribution of the incidence rate of tuberculosis. Hot spot analysis showed positive spatial correlation and obvious clustering. The GWR model (AICc=784.251) in this study had higher AICc value compared to the ordinary least squares regression (OLS) model (AICc=804.2585). The GWR model showed that the increase in the proportion of the population aged 65 and above and the proportion of the ethnic minority population had a significant promoting effect on the increase of the incidence rate of tuberculosis, and there was significant spatial heterogeneity. The effect of PM_2.5 concentration on the incidence rate of pulmonary tuberculosis varied in different regions, and the degree of effect was also different. Conclusion The proportion of people aged 65 and above and the proportion of ethnic minorities may significantly influence the incidence of pulmonary tuberculosis. The effect of PM_2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

OBJECTIVE: To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI. METHODS: From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients. RESULTS: Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation. CONCLUSION Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective:s To investigate the risk factors for delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) in patients with acute carbon monoxide poisoning (ACOP) and to develop predictive models based on machine learning algorithms.Methods:Patients with ACOP hospitalized at the First Affiliated Hospital of Zhengzhou University from August 2019 to October 2024 were included, with the occurrence of DEACMP as the outcome measure. The dataset was randomly divided into training and validation sets at a ratio of 7:3. Lasso regression was used to select features influencing the outcome in training sets. Nine machine learning models—including Random Forest (RF), Extreme Gradient Boosting (XGBoost), and Support Vector Machine (SVM)—were constructed. Receiver operating characteristic (ROC) curves were plotted and the area under the curve (AUC) calculated for each model. Calibration curves were used to assess accuracy, and decision curve analysis (DCA) was applied to evaluate clinical utility. The SHapley Additive exPlanations (SHAP) method was employed to visualize and interpret the best-performing model.Results:A total of 264 ACOP patients were included, of whom 54 (20.5%) developed DEACMP. Lasso regression identified eight key feature variables. Based on these factors, predictive models were constructed, showing good AUC stability across the nine machine learning models in both training (0.92–0.99) and validation sets (0.85–0.91). The RF model performed best, with an AUC of 0.99 in the training set and 0.90 in the validation set; its calibration curve and DCA curve also demonstrated excellent performance. SHAP analysis of the RF model revealed the importance ranking of factors from highest to lowest as follows: Glasgow Coma Scale (GCS) score, duration of coma, age, history of coronary heart disease, CK-MB level, monocyte count, diastolic blood pressure (DBP), and drinking history.Conclusions:The RF model exhibited the highest predictive performance for DEACMP occurrence in ACOP patients. The influencing factors, ranked in order of importance from highest to lowest, are as follows: GCS score, duration of coma, age, history of coronary heart disease, CK-MB level, monocyte count, DBP, and drinking history.

Objective To analyze the perioperative outcomes of cardiac valve surgery in patients with asymptomatic SARS-CoV-2 infection. Methods The perioperative clinical data of patients receiving heart valve replacement in the Department of Cardiovascular Surgery, the First Affiliated Hospital of University of Science and Technology of China from November 2022 to February 2023 were retrospectively analyzed. According to whether the patients were infected with SARS-CoV-2, they were divided into a non-infected group and an asymptomatic group. The perioperative data of the patients were compared between the two groups, and the effect of asymptomatic infection on the result of heart valve replacement surgery was analyzed. Results A total of 66 patients were enrolled including 36 males and 30 females with a mean age of 58.0±11.1 years. There were 51 patients in the non-infected group and 15 patients in the asymtomatic group. There were 2 patients of mitral valve replacement, 20 patients of aortic valve replacement, 1 patient of double valve replacement, 3 patients of aortic valve replacement with tricuspid valvoplasty, 22 patients of mitral valve replacement and tricuspid valvoplasty, 18 patients of double valve replacement and tricuspid valvoplasty. Asymptomatic infected patients received more emergency surgery than uninfected patients (26.7% vs. 0.0%, P<0.01). There was no statistical difference in the duration of extracorporeal circulation, aortic occlusion, mechanical ventilation time after the surgery, ICU stay, postoperative drainage volume, or postoperative complications between the two groups. Conclusion Perioperative results of cardiac valve surgery in patients with asymptomatic SARS-CoV-2 infection and non-infection are almost the same.

BackgroundPatients with depressive disorder commonly experience sleep disturbances. Previous studies have indicated that group exercise therapy is beneficial in alleviating depressive symptom among patients with depressive disorder. However， there is a lack of research on the impact of group exercise therapy on improving sleep quality in patients with depressive disorder. ObjectiveTo explore the impact of group exercise therapy on sleep quality in patients with acute mild-to-moderate depression during the acute phase， so as to provide references for clinically improving the sleep quality of patients with mild to moderate depressive disorder during the acute phase. MethodsFrom December 2018 to July 2021， patients with mild-to-moderate depressive disorder during the acute phase （n=40）， who met the diagnostic criteria for depressive disorder according to International Classification of Diseases， tenth edition （ICD-10） ，were recruited from the outpatient clinic of Beijing Anding Hospital， Capital Medical University. All participants underwent an 8-week moderate-intensity group exercise therapy program comprising three sessions per week， each lasting 60 minutes. Assessments were conducted at baseline and after 2， 4， 6 and 8 weeks of intervention using Visual Analogue Scale （VAS）， Hamilton Depression Scale-17 item （HAMD-17） and Pittsburgh Sleep Quality Index （PSQI）. The reduction scores at each time point relative to baseline treated as the dependent variables， time as the independent variable， baseline scores as covariates， with time as a fixed effect and baseline values as random effects. Data were analyzed using a linear mixed-effects model. ResultsThe PSQI scores of patients at baseline， 2， 4 ， 6 and 8 weeks after the intervention were （10.62±5.12）， （9.07±3.58）， （7.39±3.66）， （6.54±3.84） and （5.50±3.41）， respectively. The results of linear mixed effect model analysis showed that after 2， 4， 6 and 8 weeks of intervention， patients scored lower than baseline， with statistically significant differences observed in all cases （P<0.01）. The HAMD-17 sleep fcctor scores at baseline， 2， 4， 6 and 8 weeks were （2.25±1.56）， （2.06±1.49）， （1.36±1.27）， （1.22±1.46） and （0.97±1.34）， respectively. The results of linear mixed effects model analysis showed that the HAMD-17 sleep factor scores of 4， 6 and 8 weeks of intervention were lower than that of baseline， and the difference was statistically significant （P<0.05 or 0.01）. The VAS scores at baseline， 2， 4， 6 and 8 weeks after the intervention were （3.18±2.17）， （4.74±2.22）， （6.01±2.31）， （6.54±2.16） and （7.90±1.64）， respectively. The results of linear mixed effect model analysis showed that VAS scores of 2， 4， 6 and 8 weeks of intervention were higher than baseline，and the difference was statistically significant （P<0.01）. ConclusionGroup exercise therapy may improve sleep quality and alleviate depressive symptoms in patients with mild-to-moderate depressive disorder during the acute phase. ［Funded by National Key Research and Development Plan Project （number， 2016YFC1307200）； Beijing Municipal Hospital Scientific Research and Cultivation Plan Project （number， PX2024070）］

Objective:To construct a leadership evaluation indicator system for managers in primary healthcare institutions.Methods:This study was a qualitative research. Based on the Chinese Academy of Sciences′ Five Forces Model of Leadership, the framework of the leadership evaluation indicator system for primary healthcare institution managers was initially constructed through literature review, expert interviews, surveys, and group discussions. From November 2020 to June 2021, 19 experts were invited to participate in two rounds of Delphi expert consultations. Based on the consultation results, the leadership evaluation indicator system for primary healthcare institution managers was developed, and the analytic hierarchy process (AHP) was used to determine the weight of each indicator.Results:Nineteen consulting experts were included in the study, 13 of whom were aged 40 years or older, and seven of whom had 20 years or more of professional experience. The response rates of the two rounds of Delphi expert consultation questionnaires were 18/19 and 19/19, respectively; the authority coefficients of the experts were 0.92 and 0.91, respectively. In the second round of consultation, the coordination coefficients of each level of indicators were 0.640, 0.557, and 0.512 ( P<0.05), respectively. The constructed leadership indicator system for managers of primary healthcare institutions included five primary indicators, 16 secondary indicators, and 44 tertiary indicators. The primary indicators, in order of their weight, were "influence"(0.299),"decisiveness"(0.245),"control"(0.156),"inspiration"(0.150), and "foresight"(0.150). Conclusions:This study is a preliminary construction of a leadership evaluation indicator system for managers of primary healthcare institutions, which can be a reference for the training and evaluation of relevant talents.

【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.
