Objective: To analyze the impact of premature death due to four major chronic diseases on life expectancy in Yangpu District, Shanghai Municipality from 2010 to 2021, so as to provide the evidence for formulating chronic disease prevention and control strategies. Methods : Mortality data of registered residents in Yangpu District from 2010 to 2021 were collected through the Death Information Registration and Management System of the Shanghai Municipal Disease Control and Prevention Information Management Platform. The premature death probability of malignant tumors, diabetes, cardiovascular and cerebrovascular diseases, and chronic respiratory diseases, and life expectancy of residents were calculated using the abridged life table method. Trends in premature death probability for four types of chronic diseases were analyzed using the average annual percent change (AAPC). The impact of premature death probability due to four chronic diseases on life expectancy was assessed by Arriaga's decomposition method. Results : The premature death probability due to four major chronic diseases in Yangpu District decreased from 9.88% in 2010 to 9.22% in 2021, showing an overall declining trend (AAPC=-0.540%, P<0.05). Among females, the premature death probability declined from 6.71% to 4.90% (AAPC=-2.715%, P<0.05), whereas no statistically significant trend was observed in males (P>0.05). Life expectancy increased from 82.52 years in 2010 to 84.50 years in 2021, with an overall upward trend (AAPC=0.244%, P<0.05). Life expectancy rose by 1.71 years for males and 2.34 years for females (AAPC=0.197% and 0.303%,both P<0.05). Declines in premature death probability from malignant tumors (AAPC=-0.967%, P< 0.05) and chronic respiratory diseases (AAPC=-3.071%, P<0.05) contributed to gains in life expectancy of 0.30 years and 0.03 years, with contribution rates of 12.18% and 1.29%, respectively. Changes in premature death probability due to diabetes as well as cardiovascular and cerebrovascular diseases were not statistically significant (both P>0.05), resulting in reductions in life expectancy of 0.05 years and 0.10 years, with contribution rates of -2.40% and -5.05%, respectively. Notably, an increase in premature death probability due to cardiovascular and cerebrovascular diseases among males (AAPC=1.673%) contributed to a decrease of 0.22 years in male life expectancy, whereas a decrease among females (AAPC=-3.824%) contributed to an increase of 0.03 years in female life expectancy, with contribution rates of -13.03% and 1.14%, respectively. Conclusions From 2010 to 2021, Yangpu District experienced an overall decline in premature death probability due to four major chronic diseases and an increase in life expectancy. Greater attention should be paid to the negative impacts of premature death probability from diabetes as well as cardiovascular and cerebrovascular diseases among males on life expectancy.

Objective To observe the impact of brain-computer interface(BCI)robot combined with task-oriented training(TOT)on hand function and activities of daily living in stroke patients.Methods A total of 40 patients with subacute stroke who were hospitalized in the Department of Rehabilitation Medicine of Anhui No.2 Province People's Hospital from December 2022 to December 2024 were prospectively and consecutively included in this study.The stroke patients were randomly assigned to the experimental group and the control group using the random number table method,with 20 cases in each group.Baseline data were collected from all patients,including gender,age,personal history(smoking,drinking),past medical history(hypertension,diabetes),stroke type(hemorrhagic stroke,ischemic stroke),hemiplegia side(left,right),disease course,stroke location(basal ganglia,internal capsule),and admission assessment indicators(including kinesthetic and visual imagery questionnaire[KVIQ-20]score,mini-mental state examination[MMSE]score and National Institutes of Health stroke scale[NIHSS]score).Both groups of patients received conventional rehabilitation training and TOT.The experimental group then underwent BCI robot training combined with TOT on this basis.Both groups received treatments for 4 weeks,and the upper limb and hand functions of all patients were evaluated using the Fugl-Meyer upper extremity function assessment scale(FMA-UE),the wrist-hand part of the FMA-UE scale(FMA-WH),the Wolf motor function test(WMFT),and the modified Ashworth scale(MAS)before and after the treatment;the hand function related part(feeding[10 score],bathing[5 score],dressing[10 score],grooming[5 score],and toilet using[10 score])of modified Barthel index(MBI)was used to assess the patients'hand dexterity to perform daily activities.Results(1)No statistically significant differences were found in the baseline data between the two groups of patients(all P＞0.05).(2)Before treatment,the scores of FMA-UE,FMA-WH,WMFT,MAS and hand function related score of MBI in the experimental group were(18.75±7.38),(2.95±1.54),(26.90±8.69),(1.10±0.66),and(15.45±1.82)respectively,while those in the control group were(15.90±5.39),(2.25±1.12),(24.15±6.78),(1.25±0.60),and(15.65±3.12)respectively.There were no statistically significant differences in the scores of FMA-UE,FMA-WH,WMFT,MAS and hand function related score of MBI between the two groups before treatment(all P＞0.05).After 4 weeks of treatment,the scores of FMA-UE,FMA-WH,WMFT,MAS and hand function related score of MBI in the experimental group were(27.10±7.76),(5.75±2.97),(40.85±10.19),(0.73±0.57),and(21.15±2.66)respectively,while those in the control group were(21.25±5.29),(4.00±1.49),(31.85±7.60),(0.73±0.64),and(17.40±3.14)respectively.The time main effects(Ftime values were 925.061,138.138,624.635 and 405.986 respectively,all P＜0.01),group main effects(Fgroup values were 4.460,4.562,5.011 and 4.411 respectively,all P＜0.05),and the interaction effects of time and group(Ftime×group values were 44.358,7.356,52.506 and 114.128 respectively,all P＜0.05)of FMA-UE,FMA-WH,WMFT and hand function related score of MBI scores were all significant.The time main effect of MAS scores was significant(Ftime value was 59.478,P＜0.01),while the group main effect(Fgroup value was 0.162,P＞0.05),the interaction effects of time and group(Ftime×group value was 1.652,P＞0.05)were not significant.Conclusion The combined task-oriented training with BCI robots can improve the upper limb and hand functions of stroke patients,enhance their ability to perform daily activities,and the effect is superior to that of single task-oriented training.

Objective To observe the effect of sevoflurane(SEV)on the expression of myocardial biological clock gene aromatic hydrocarbon receptor nuclear transport-like protein 1(BMAL1)in diabetic rats and to explore its changes.Methods Sixty healthy male SD rats with a body mass of 200-250 g were divided into oxygen inhalation group(NC)and sevoflurane inhalation group(SEV).The diabetic model was routinely replicated,and the model was divided into oxygen group(DM)and sevoflurane group(DM+SEV)with an inhalation time of 5 h(n=15).Four groups of experimental animals were executed at 0,12 and 24 h after the anesthesia was stopped and then myocardial tissue was isolated.Western blot was used to determine the expression level of biological clock gene BMAL1 protein and its activation enzyme USP9X;HE staining microspy to observe the pathological changes of my-ocardial tissue and immuno-fluorescence co-localization to observe the relationship between USP9X and BMAL1.Results At 0 and 12 h after stopping anesthesia,the expression of BMAL1 and USP9X in the DM+SEV group was significantly down-regulated as compared with the DM group,and the expression of BMAL1 and USP9X in the DM+SEV group was significantly down-regulated(P<0.05)at 24 h after stopping anesthesia(P>0.05).HE staining microscopy found changes of myocardial tissue structure in the DM+SEV group at 0 and 12 hrs after stopping anes-thesia.This change was most significant at 0 h after stopping anesthesia,but the myocardial tissue structure was neatly arranged at 24 h.The results of immuno-fluorescence colocalization showed that USP9X and BMAL1 proteins were mainly distributed in the cytoplasm of cardio-myocardium with and overlapping parts between them.Under the influence of sevoflurane,there was less overlap between the two at 0 and 12 hrs after stopping anesthesia and more overlap between the two at 24 h,which was close to that of the DM group.Conclusions Sevoflurane reversibly changes the expression of myocardial circadian clock gene BMAL1 in diabetic rats and this change still existe for 12 h after stopping anesthesia,then significantly fade away 24 hrs after stopping anesthesia.

Objective To investigate the characteristics of thickness changes in peripapillary retinal nerve fiber layer(pRNFL)and identify related risk factors in patients with Moyamoya disease(MMD).Methods A retrospective study was conducted on 150 MMD patients(150 eyes)aged 6-65 years admitted to the Neurosurgery Department of the Fifth Medical Center,Chinese PLA General Hospital from May 2016 to December 2023(observation group),and 150 age-matched healthy volunteers(150 eyes)from the hospital's ophthalmology outpatient department(control group).Both groups were subdivided into pediatric(≤18 years),young adult(18-40 years),and middle-aged(40-65 years)subgroups.The pRNFL thickness in four quadrants was measured by optical coherence tomography(OCT):superior(pRNFL-Sup),inferior(pRNFL-Inf),nasal(pRNFL-Nas),temporal(pRNFL-Tmp),and average thickness(pRNFL-Avg).General clinical data and pRNFL thickness were compared between two groups.Univariate and multivariate logistic regression analyses were performed to identify risk factors for pRNFL thinning in MMD patients.The cohort was randomly divided into training(n=210)and validation(n=90)sets at a 7:3 ratio.A predictive model for pRNFL thinning in MMD patients was constructed based on logistic regression results.Model performance was evaluated using the area under the receiver operating characteristic curve(AUC),and clinical utility was assessed via decision curve analysis.Results Compared with control group,MMD patients exhibited significantly reduced pRNFL-Avg,pRNFL-Sup,pRNFL-Tmp,and pRNFL-Inf thickness(P<0.05 or P<0.001),while pRNFL-Nas showed no significant difference(P>0.05).In the pediatric subgroup,pRNFL-Avg and pRNFL-Inf were thinner(P<0.05).In the young adult subgroup,pRNFL-Avg and pRNFL-Sup were reduced(P<0.001 or P<0.05).In the middle-aged subgroup,pRNFL-Avg,pRNFL-Sup,pRNFL-Inf,and pRNFL-Tmp were all thinner(P<0.05 or P<0.001).Multivariate logistic regression identified visual field defects(OR=15.28,95%CI 2.95-79.10),disease duration(OR=1.11,95%CI 1.05-1.18),and the number of involved cerebral vessels(OR=1.49,95%CI 1.01-2.22)as independent risk factors for pRNFL thinning.The predictive model achieved AUC of 0.94(95%CI 0.91-0.97)and 0.95(95%CI 0.91-0.99)in the training and validation sets,respectively.Decision curve analysis confirmed the model's favorable clinical net benefit.Conclusion Thinning of pRNFL was observed in Moyamoya disease patients with visual field defects,disease duration,and cerebral vascular involvement identified as independent risk factors for pRNFL atrophy.

Objective To explore the mechanism by which curcumin improves behavioral deficits in mice with Parkinson's disease(PD)through fecal microbiota transplantation.Methods A subacute model of PD in mice was induced by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP).Fecal microbiota from both the model group and the curcumin(Cur)-treated group(80 m g/kg)were collected and analyzed.The experiment involving fecal microbiota transplantation was structured into four distinct groups,fecal microbiota solvent transplantation group(FMTcon),model fecal microbiota transplantation group(FMTmodel),MPTP-induced model group(model),and model group subjected to fecal microbiota transplantation following curcumin treatment(model+FMTCur).The motor skills of the mice were assessed by using rod rotation,pole climbing experiment,and open field tests.Immunofluorescence techniques were employed to observe the expression tyrosine hydroxylase(TH)-positive neurons in the substantia nigra of the brain.Additionally,the gene expression of tumor necrosis factor-α(TNF-α)in the midbrain of mice was analyzed,alongside the protein expression of nuclear factor-κB(NF-κB)and nucleotide binding oligomerization domain-like receptor protein 3(NLRP3).Results The subacute PD animal model in mice was successfully established,and fecal microbiota were separated and gathered.The model group exhibited significant motor impairment,as evidenced by a shortened rod rotation time(P＜0.05),prolonged pole climbing time(P＜0.05),significantly reduced total movement distance within the open field(P＜0.001),and decreased time spent in the central zone(P＜0.01).The relative expression level of TH+neurons in the substantia nigra was significantly reduced(P＜0.01).Moreover,mRNA expression of TNF-α in the midbrain increased significantly(P＜0.01),along with significant elevations in protein expression of NF-κB(P＜0.001),phosphorylated NF-κB(p-NF-κB)(P＜0.01),NLRP3(P＜0.001),and Caspase-1(P＜0.01).The transplanted model microbial group(FMTmodel)also exhibited motor impairment,manifested by a trend of shortened rod rotation time,prolonged pole climbing time,a significant decrease in total movement distance within the open field(P＜0.01),and a trend of shortened time spent in the central zone.The relative expression level of TH+neurons in the substantia nigra decreased significantly(P＜0.05).Additionally,mRNA expression of TNF-α in the midbrain increased significantly(P＜0.01),along with notable elevations in the protein expression of NF-κB(P＜0.05),and Caspase-1(P＜0.01).Treatment with curcumin in the fecal microbiota transplantation group of mice(model+FMTCur)showed improvements in motor abilities,evidenced by shortened pole climbing time(P＜0.05),significantly prolonged rod rotation time(P＜0.01),and extended time spent in the central zone(P＜0.05).The relative expression level of TH+dopaminergic neurons in the substantia nigra increased significantly(P＜0.05).Moreover,mRNA expression of TNF-α in the midbrain decreased significantly(P＜0.01),along with notable reductions in the protein expression of NF-κB(P＜0.001),p-NF-κB(P＜0.01),NLRP3(P＜0.05),and Caspase-1(P＜0.01).Conclusion Fecal microbiota transplantation in PD model mice can induce behavioral deficits,damage TH+neurons in the substantia nigra,and trigger neuroinflammation in the brain.Subsequent curcumin treatment can ameliorate these deficits,reverse damage to TH+neurons,reduce neuroinflammatory factors,and decrease the expression of NF-κB and NLRP3 pathways.This preliminary evidence suggests that curcumin may improve Parkinsonian behavioral deficits in mice by modulating the gut microbiota.

ObjectiveTo understand the incidence and mortality trends of acute cardiovascular and cerebrovascular events in Yangpu District of Shanghai from 2009 to 2022, and provide a basis for the prevention and control of cardiovascular and cerebrovascular events. MethodsData were obtained from the Shanghai Acute Cardiovascular and Cerebrovascular Events Surveillance Platform. Data on the incidence and mortality of cardiovascular and cerebrovascular events in the population (age group, gender) from 2009 to 2022 were collected, and the Joinpoint Regression Program version 4.9 was used to calculate the average annual percent change (AAPC) in the incidence and mortality rates of acute cardiovascular and cerebrovascular events. ResultsFrom 2009 to 2022, the crude incidence and standardized incidence rate of acute cardiovascular and cerebrovascular events in Yangpu District showed no significant changes (AAPC=1.41%, P=0.569; AAPC=-1.03%, P=0.675), the crude mortality rate of acute cardiovascular and cerebrovascular events in Yangpu District did not change significantly (AAPC=-3.04%, P=0.213), while the standardized mortality rate showed a decreasing trend (AAPC=-6.23% P=0.014). From 2009 to 2022, the crude incidence rates and age-standardized incidence rates for both males and females in Yangpu District showed no significant changes. The crude mortality trends for both genders were not significant, while the age-standardized mortality rates showed a decline (AAPC=-5.33%, P=0.029; AAPC=-7.50%, P=0.006). The incidence rate and age-standardized incidence rate were higher in males than in females. The crude incidence rates in the 30‒, 40‒, and 45‒year-old age groups increased annually (AAPC=9.13%、7.11%、4.67%, all P=0.001), and the crude mortality ratse in the 60‒, 65‒, 70‒, 75‒, 80‒, and 85‒year-old age groups declined annually (AAPC=-4.24%, P=0.044; AAPC=-5.41%, P=0.028; AAPC=-6.73%, P=0.004; AAPC=-7.46%, P=0.002; AAPC=-8.24%, P=0.002; AAPC=-6.16%, P=0.035). ConclusionFrom 2009 to 2022, the crude incidence, standardized incidence rate and crude mortality rate of cardiovascular and cerebrovascular events in Yangpu District tended to be stable, and the standardized mortality rate showed a downward trend. Men, middle-aged and young people were the key groups in the prevention and treatment of cardiovascular and cerebrovascular diseases, and it should be continued to improve the ability of medical emergency and increase the integration of medical and prevention.

Objective To explore the potential categories of health risk behaviors among students aged 11 to 18 years in Minhang District,Shanghai in order to identify the influencing factors of health risk behaviors among different categories of students.Methods Using stratified cluster sampling techniques,a random selection of 1 690 middle school students from Minhang District,Shanghai,were chosen as the study sample.Data was collected using the"Shanghai Adolescent Health-Related Behavior Survey Questionnaire"to assess participants'scores on six categories of health risk behaviors.Latent profile analysis(LPA)was employed to cluster students'health risk behaviors,and a multifactorial Logistic regression model was used to analyze the related influencing factors.Results The health risk behaviors of students aged 11 to 18 in Minhang District,Shanghai,were categorized into 3 groups:Class 1,comprising 915 students(54.14%),with moderate to low scores in health risk behaviors,named"the group with moderately low levels of various health risk behaviors";Class 2,comprising 539 students(31.89%),with higher scores in psychological addiction,named"the group with psychological addiction as the prominent health risk behavior";Class 3,comprising 236 students(13.97%),with higher scores in substance addiction,named"the group with substance addiction as the prominent health risk behavior".The results of the univariate analysis for the three potential categories of student health risk behaviors show that there are statistically significant differences in the 3 potential categories of health risk behaviors among students of different schools,ages,ethnicities,and boarding situations(P<0.05).The analysis results of the multivariate Logistic regression indicate that compared to junior high school students,both senior high school students and vocational high school students have a higher risk of exhibiting unhealthy behaviors characterized by psychological addiction and substance addiction,with all differences being statistically significant(P<0.05).Conclusion The latent profile analysis reveals three distinct categories of health risk behaviors among students aged 11 to 18 years in Minhang District,Shanghai,with significant distribution differences among students from diverse backgrounds.Consequently,it is recommended that tailored health education and intervention measures be implemented for students with different school characteristics and at various educational stages.

Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

Objective　To analyse the crude detection rate and trends of newly detected HIV/AIDS cases in medical institutions in China from 2017 to 2023, and to provide a reference for optimizing HIV testing strategies in medical institutions. Methods　Data on HIV testing and newly reported HIV/AIDS cases were analysed using data from the Comprehensive AIDS Prevention and Control Information System of the China Information System for Disease Control and Prevention for the period from 2017 to 2023. HIV testing in medical institutions includes patients tested preoperatively, those tested before transfusion, those tested in sexually transmitted disease (STD) clinics, prenatal care clinics, and other types of patients. Descriptive statistical analysis and χ2 test were performed using SAS 9.4 software. Joinpoint regression was performed using Joinpoint 4.9.0 software to analyse trends of the crude detection rates over time. Results　From 2017 to 2023, the person-times of HIV tests in medical institutions increased from 143 million to 255 million, with an increase of 78.07%. The number of newly detected HIV/AIDS cases increased from 74 000 to 88 000 and then declined to 69 000. The crude detection rate of new HIV/AIDS cases declined from 5.18/10 000 to 2.71/10 000, showed a declining trend, the mean annual percentage change was -9.99%(P<0.001). The crude detection rate of new HIV/AIDS cases in STD clinics was the highest among all types of clinic visits (12.79/10 000-24.47/10 000), and the crude detection rate of new cases among all types of clinic visits showed a decreasing trend(P<0.05). Among different medical institutions, general hospitals were the most important source of the number of tests and the number of newly detected HIV/AIDS cases, accounting for more than 62.93% and 62.68%, respectively. Specialised medical institutions had the highest crude detection rate of new cases, which was maintained at more than 5.13/10 000. The crude detection rate of new cases for all four types of medical institutions, except for primary medical institutions, showed a decreasing trend (P<0.05). Conclusions　The detection rate of new cases in medical institutions showed a decreasing trend in 2017-2023, and the efficiency of STD clinics testing and detection was higher among all types of attendees. General hospitals are the main source of new cases detection, and testing in specialised medical institutions is more efficient. Testing should be strengthened in key groups of patients and in key medical institutions.
