Objective: To investigate the current status and influencing factors of moderate and severe injuries caused by falls among the elderly in Longhua District, Shenzhen City, Guangdong Province, so as to provide a basis for formulating prevention and control policies and intervention measures. Methods: Data on elderly patients (aged ≥60 years) who sought first-time outpatient or emergency treatment for falls at sentinel hospitals in Longhua District from January 1, 2021, to December 31, 2024, were collected through the Shenzhen Injury Surveillance System. The data included general information, basic characteristics of the fall incidents, and clinical characteristics of the fall-related injuries. Factors affecting moderate and severe injuries caused by falls among the elderly were analyzed using a multivariable logistic regression model. Results: A total of 2 797 elderly fall cases were reported in Longhua District from 2021 to 2024, including 990 males (35.40%) and 1 807 females (64.60%). The mean age was (70.56±8.85) years. There were 1 305 cases of moderate and severe injuries, accounting for 46.66%. Multivariable logistic regression analysis showed that female (OR=1.428, 95%CI: 1.211-1.684); 70-<80 years (OR=1.391, 95%CI:1.153-1.679), or ≥80 years (OR=1.586, 95%CI: 1.260-1.996); falls occurring at home (OR=1.659, 95%CI: 1.142-2.409), or in public residential settings (OR=1.666, 95%CI: 1.029-2.697); and activities during the fall such as walking (OR=1.738, 95%CI: 1.383-2.183) or performing life activities (OR=1.562, 95%CI: 1.254-1.947) were associated with a higher risk of moderate and severe injuries among elderly fall cases. High school/secondary technical school education level (OR=0.695, 95%CI: 0.526-0.919) and occupation as professional and technical/clerical staff (OR=0.540, 95%CI: 0.310-0.942) were associated with a lower risk of moderate and severe injuries among elderly fall cases. Conclusions The proportion of moderate and severe injuries caused by falls among the elderly in Longhua District is relatively high, which is mainly associated with gender, age, education level, occupation, fall location and activity during the fall.

Objective:To investigate the relationship between lipid levels and cognitive impairment in the elderly Chinese population using prospective cohort data.Methods:Based on the China-PAR (Prediction for Atherosclerotic Cardiovascular Disease Risk in China) cohort, this study included 24 380 individuals aged ≥60 years who participated in the cognitive function follow-up survey from 2018 to 2019. Cognitive function was assessed using the Mini-Mental State Examination (MMSE), with cognitive impairment defined according to different educational levels: MMSE ≤17 for illiterate individuals, MMSE ≤20 for those with primary education and MMSE ≤24 for those with secondary education or above. Multivariable linear regression and logistic regression models were employed to examine the associations between six baseline lipid indicators and cognitive scores, as well as cognitive impairment. Additionally, restricted cubic splines were used to explore the exposure-dose relationship between lipid levels and cognitive function.Results:The study population had a median follow-up time of 11.6 years, with a baseline age of (59.7±6.8) years. Among the participants, 9 510 (39.0%) were males, and the mean MMSE score was 24.7±6.8. A total of 3 887 individuals (15.9%) were identified as cognitively impaired. The results of multivariable linear regression and logistic regression indicated that total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) levels were not only significantly positively associated with cognitive scores but also significantly associated with a lower risk of cognitive impairment. Each 1 mmol/L increase in these lipid levels corresponded to β values (95% CI) of 0.267 (0.173-0.361), 0.385(0.271-0.499) and 0.331(0.231-0.431), respectively. Each 1 mmol/L increase in these lipid levels corresponded to odds ratio ( OR) (95% CI) values of 0.915 (0.876-0.956), 0.875 (0.830-0.923) and 0.886 (0.848-0.927), respectively. The dose-response curve demonstrated that the negative association was primarily observed within the guideline-recommended optimal lipid level range. Specifically, when LDL-C was less than 3.4 mmol/L and non-HDL-C was less than 4.1 mmol/L, the corresponding OR (95% CI) values were 0.859 (0.796-0.926) and 0.876 (0.818-0.939). Conclusion:Lipid levels exhibit a certain linear negative association with cognitive impairment in elderly Chinese adults, with LDL-C and non-HDL-C demonstrating a stronger effect, particularly within the guideline-recommended optimal range.

Disrupted bone morphogenetic protein type 2 receptor (BMPR2) signaling in endothelial cells drives pulmonary arterial hypertension (PAH). However, targeted recovery of this signaling pathway by lipid nanoparticles (LNPs) has not been explored as a therapy. Here, we employed Design of Experiments to optimize the delivery efficiency of LNPs targeting pulmonary endothelial cells developed by our laboratory, resulting in a remarkable 35-fold increase in a simplified three-component formulation without helper lipids. Administration of BMPR2 mRNA LNPs effectively reversed established PAH in two experimental rat models (monocrotaline or SU5416-hypoxia) by reversing pulmonary vascular remodeling. Specifically, BMPR2 mRNA LNPs replenished the expression of BMPR2 protein and subsequently activated downstream pathways, as confirmed by elevated levels of p-SMAD1/5/9 and ID1 proteins. The relief of pulmonary arterial occlusion was demonstrated by thinned pulmonary arterial media and decreased proportion of full muscularized vessels. Alleviation of right ventricular hypertrophy was indicated by declined Fulton index, the cross-sectional area of right ventricular cardiomyocytes as well as collagen deposition. Effective recovery of right ventricular function was evidenced by increased pulmonary artery flow acceleration time/pulmonary artery flow ejection time ratio. These findings underscore the potential of restoring BMPR2 signaling through pulmonary endothelial cell-specific LNPs for treating PAH.

Objectives:This study aims to investigate the association between Chinese visceral adiposity index(CVAI)and the risk of cardiovascular disease(CVD),and explore the sex differences.Methods:Participants were screened from the three sub-cohorts of Prediction for Atherosclerotic Cardiovascular Disease Risk in China(China-PAR)project,baseline information on body measure and biochemistry examinations were collected from 1998,2000-2001,and 2007-2008,separately.Participants were followed up to 2015.Cohort-stratified Cox proportional risk models were used to analyze the relationship between CVAI,both in continuous(per standard deviation increase)and categorical(quartiles,with Q1 as reference)scales,and CVD risk in the total population,men and women.The multiplicative interaction between sex and CVAI on CVD risk were calculated.Restricted cubic spline regression was employed to investigate the dose-response relationship.Results:A total of 98 464 participants without CVD at baseline were included.During the 723 508 person-years of follow-up,3 605 CVD events were recorded.After multivariate adjustment,the HRs(95％CIs)of CVD were 1.25(1.20-1.29),1.09(1.04-1.15),and 1.54(1.46-1.64)for per standard deviation increment in CVAI in the general population,men and women,respectively.Besides,compared with Q1 group,the HRs(95％CIs)in Q4 group were 1.87(1.67-2.10),1.33(1.14-1.54)and 3.84(3.09-4.78),correspondingly,and the effect of CVAI on the risk of CVD was significantly higher in women than in men(Pinteraction<0.05).Additionally,there was a positive dose-response relationship between CVAI and the risk of CVD.Conclusions:Elevated CVAI is an independent risk factor for CVD,especially in women.

Colorectal cancer is the third leading cause of cancer-related mortality worldwide.Hepatic resection is the standard treatment for colorectal cancer liver metastasis.Microwave ablation(MWA),as a minimally invasive therapeutic approach,offers an alternative treatment option for these patients.But the clinical efficacy of hepatic resection and MWA in treating colorectal cancer liver metastasis patients is still inconclusive.Literatures were retrieved on comparative studies about the treatment of colorectal cancer liver metastasis with hepatic resection and MWA from multiple databases,including sinoMed,PubMed,Web of Science,EMBASE,CNKI,Wanfang,etc.The cutoffdate of retrieval was September 2024.Finally,a total of 13 studies comprising 2 057 patients,were included in this study.The papers were assessed using the Newcastle-Ottawa Scale and Jadad Scale.All included studies were of high quality.Data extraction focused on postoperative complications,length of hospital stay,surgical duration,hospitalization costs,and patient survival outcomes,including overall survival(OS)and disease-free survival(DFS).A meta-analysis was performed using Review Manager 5.4 software.There were no significant differences in OS(HR=1.03,95%CI:0.85-1.25,P=0.77)and DFS(HR=1.27,95%CI:0.94-1.71,P=0.13)between the MWA group and the hepatic resection group.In the subgroup analysis of patients with≤5 liver metastases and size of metastases≤3 cm,there were no statistically significant differences in OS and DFS between the MWA group and the hepatic resection group.The MWA group exhibited shorter hospital stay,reduced hospitalization costs,decreased surgical duration,less intraoperative blood loss,and lower incidence of complications compared to the hepatic resection group(P＜0.05).Therefore,for patients with colorectal liver metastases characterized by a number of liver metastases≤5 and size of metastases≤3 cm,MWA serves as an effective alternative to hepatic resection,with a lower morbidity associated with treatment.Further validation of these findings is warranted through additional randomized controlled trials and cohort studies.The registration number of this Meta-analysis on the PROSPERO platform is CRD42024610278.

Objectives:To explore the independent and combined effects of sleep duration and physical activity(PA)on the incidence of cardiovascular disease(CVD).Methods:The study subjects were derived from three sub-cohorts of the China-PAR project.Information on sleep and PA was collected from the surveys conducted in 2007-2008,and the incidence and mortality data of CVD were obtained during the follow-up survey from 2012 to 2015.Sleep duration was categorized into≤6 h/d,>6-8 h/d,and>8 h/d,and the PA level was classified according to the tertiles of PA volume(MET-h/d).The Cox proportional hazards model stratified by cohort source was applied to estimate the associations of PA and sleep duration with CVD incidence,coronary heart disease(CHD)incidence,and stroke incidence.Results:A total of 93 933 participants were included.During an average follow-up of(5.82±0.98)years,3 862 CVD events were documented.Compared with the low PA group,the hazard ratios(HRs)and 95%confidence intervals(CIs)of the CVD incidence,CHD incidence,and stroke incidence for the high PA group were 0.73(0.65-0.82),0.62(0.49-0.77)and 0.88(0.76-1.01),respectively.A U-shaped relation between sleep duration and incidence of CVD and stroke was observed.Compared with those who slept for>6-8 h/d,the risk of CVD(HR[95%CI]:1.10[1.00-1.21],P=0.04)and stroke(HR[95%CI]:1.33[1.18-1.49],P<0.01)was higher among participants slept>8 h/d.The risk of CVD,CHD and stroke tended to be higher in the≤6 h/d sleep group.Compared with the high PA combined with>6-8 h/d,the risk of stroke was highest in the high PA combined with>8h/d sleep group(HR[95%CI]:1.74[1.37-2.22],P<0.05),while the risks of CVD(HR[95%CI]:1.69[1.39-2.04],P<0.05)and CHD(HR[95%CI]:1.99[1.41-2.81],P<0.05)were highest in the low PA combined with≤6 h/d sleep group.Conclusions:Adequate physical activity and appropriate sleep duration are associated with lower risk of morbidity from CVD,CHD and stroke.

Background::Statins are the first line of treatment for dyslipidemia, but their side effects often reduce medication compliance. Natto and red yeast rice are natural ingredients with lipid-lowering effects. However, the efficacy of Natto Red Yeast Rice (NRYR) supplement in combination with statins in regulating blood lipid levels has not been fully evaluated.Methods::A multicenter, double-blinded, randomized-controlled trial was conducted among individuals with low-density lipoprotein cholesterol (LDL-C) of 3.4 to 5.0 mmol/L at six sites in China, of those at moderate risk of cardiovascular disease (CVD) are prioritized. Participants are enrolled and randomly assigned into four groups by a combination of NRYR (or its placebo) and Simvastatin (or its placebo) in a ratio of 1:1:1:1. After examination at baseline, all participants underwent intervention for 3 months and two follow-up visits at 1 month and 3 months after the intervention. The primary outcome is the change in LDL-C level at 3 months, and secondary outcomes include changes in levels of other lipid profiles and biomarkers, as well as calculated 10-year CVD risk. A total of 1136 participants were randomly assigned, of whom 1110 received the intervention.Discussion::This study may provide new evidence for the efficacy of NRYR supplement in combination with statins to regulate lipid levels and optimize lipid management.Trial Registration::Chinese Clinical Trial Registry database: registration nos.

Objective To investigate the effects of emergency endovascular treatment on the short-term and long-term prognosis of patients with minor stroke(National Institutes of Health stroke scale[NIHSS]score≤5)caused by posterior circulation large vessel occlusion(LVO).Methods A retrospective analysis was performed on consecutive patients with minor stroke caused by posterior circulation LVO admitted to the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University from July 2019 to March 2024.The patients were divided into the emergency endovascular treatment group and the standard medical treatment group according to the treatment method.Baseline and clinical data were collected from all patients enrolled,including age,sex,smoking history,history of alcohol consumption,medical history(hypertension,diabetes,hyperlipidemia,atrial fibrillation,transient ischemic attack[TIA],blood pressure on admission,stroke history,coronary heart disease),intravenous thrombolysis,tandem lesions,posterior circulation Alberta stroke program early CT score(pc-ASPECTS)on admission,NIHSS score on admission and discharge,time from onset to admission,responsible occluded vessel(basilar artery,left vertebral artery,right vertebral artery),vertebral artery development(left vertebral artery dominant,right vertebral artery dominant,bilateral vertebral artery dominant),non-lesion side vertebral artery development(poor,good,not applicable),basilar artery on CT angiography(BATMAN)score,leptomeningeal branch compensation(open,not open),surgery-related indicators(number of thrombectomy passes[≤2 times,＞2 times],rescue interventions[stent placement,balloon dilation,arterial thrombolysis,intra-arterial tirofiban infusion],immediate postoperative modified thrombolysis in cerebral infarction[mTICI]grade≥2b[successful recanalization],anesthesia method[general,local],endotracheal intubation status[yes,no],duration of mechanical ventilation[not using a ventilator or successfully intubation for≤24 hours and＞24 hours]),in-hospital systematic complications(deep-vein thrombosis,urinary tract infection,lung infection).The primary outcome for short-term prognosis was an excellent outcome(modified Rankin scale[mRS]score of 0-1)within 90 days after onset.Secondary outcomes included a good outcome(mRS score of 0-2)within 90days after onset,recurrent ischemic stroke within 90 days after onset,all-cause mortality within 90 days after onset.Safety outcomes were symptomatic intracerebral hemorrhage(sICH)within 24 hours of treatment(NIHSS score increased by≥4 points or increased level of consciousness score by≥1 point compared with admission,with visible hemorrhagic lesions on follow-up CT scan)and early neurological deterioration(END,NIHSS score increased by≥2 points or motor score increased by≥1 point compared with admission,within 24 hours after treatment).Long-term outcome was defined as recurrent ischemic stroke within 1 year after onset.Short-term and safety outcomes were compared between the emergency endovascular treatment group and the standard medical treatment group.Kaplan-Meier survival curves was used to evaluate the effect of emergency endovascular treatment on the long-term prognosis.Based on the mRS score at 90 days from onset,all patients were divided into an excellent outcome(mRS score 0-1)group and a non-excellent outcome(mRS score 2-6)group.Baseline and clinical data were compared across the two groups.Variables with statistically significant differences were included in the multivariate Logistic regression analysis to investigate the influencing factor of 90-day excellent outcomes in patients with minor stroke caused by posterior circulation LVO.Results A total of 56 patients with minor stroke caused by posterior circulation LVO were enrolled,including 18 patients in the emergency endovascular treatment group and 38 patients in the standard medical treatment group.45 patients achieved excellent outcomes and 11 patients achieved non-excellent outcomes.(1)The emergency endovascular treatment group had lower pc-ASPECTS on admission(8.0[7.0,9.0]points vs.9.0[8.0,10.0]points,P=0.043)and There were no statistically significant differences in the excellent outcome rate,good outcome rate,and ischemic stroke recurrence rate within 90 days after onset between the two groups(all P＞0.05).No all-cause mortality occurred within 90 days after onset in either group.In the emergency endovascular treatment group,one patient developed sICH and one developed END within 24 hours after treatment.(3)No recurrent ischemic stroke in the emergency endovascular treatment group within 1 year after onset,while 3cases(7.89%)of recurrence were observed within 1year after onset in the standard medical treatment group.The Kaplan-Meier survival curve analysis showed that there was no statistically significant difference in the incidence of ischemic stroke within one year after onset between the two groups(P=0.341).(4)There were statistically significant differences between patients with excellent outcome and patients with non excellent outcome in drinking history,diabetes history,NIHSS score after discharge,distribution of responsible occlusive vessels,and distribution of vertebral artery development(all P＜0.05).The results of multivariate Logistic regression analysis showed that the NIHSS score at discharge was an independent influencing factor for excellent outcome at 90 days after onset in patients with minor stroke caused by posterior circulation LVO(OR,0.448,95%CI 0.275-0.728,P=0.001).Conclusions This study shows potential safety and effectiveness of emergency endovascular treatment on patients with minor stroke caused by posterior circulation LVO,but it is not superior to standard medical treatment in terms of short-term and long-term outcomes.Further large-sample randomized controlled trials are warranted to validate the findings of this study.
