Objective To analyze the prevalence and related risk factors of mild cognitive impairment (MCI) in the elderly in Zhoukanghang region of Pudong New Area,Shanghai. Methods Clinical data of 1537 elderly people (aged≥60 years old) in Zhoukanghang region of Pudong New Area,Shanghai from Aug. 2019 to Sep. 2022 were collected. Demographic data,cardiovascular risk factors (blood pressure,blood glucose,blood lipids,etc.),family history of dementia,cerebrovascular history,and hippocampal magnetic resonance imaging data were collected,and the MCI was tested by the simple mental state scale (MMSE) and Montreal cognitive assessment (MoCA). According to the clinical diagnostic criteria of MCI,the subjects were divided into MCI group and non-MCI group. The clinical data were compared between the 2 groups,and the independent risk factors of MCI were analyzed by multivariate logistic regression analysis. Results Among the 1537 subjects,226 cases (14.70％) were MCI patients and 1311 cases (85.30％) were non-MCI individuals. Among the 226 patients with MCI,138 had single domain amnestic MCI,33 had multiple domain amnestic MCI,11 had single domain non-amnestic MCI,and 7 had multiple domain non-amnestic MCI. The proportions of male,diabetes mellitus,hyperlipidemia,family history of dementia and cerebrovascular disease in the MCI group were significantly higher than those in the non-MCI group (all P<0.05),and the hippocampal atrophy was significantly higher than that in the non-MCI group (P<0.01). Multivariate logistic regression analysis showed that family history of dementia,cerebrovascular history and hippocampal atrophy were independent risk factors for MCI in the elderly (all P<0.05). Totally 214 patients with MCI were followed up to Feb. 2023,of which 20 cases (9.35％) were diagnosed as Alzheimer's disease and 4 cases (1.87％) as Lewy bodies dementia. Conclusion The prevalence of MCI in the elderly in Zhoukanghang region of Pudong New Area,Shanghai is 14.70％. Family history of dementia,cerebrovascular disease and hippocampal atrophy are independent factors for MCI in the elderly.

【Objective】 Coronary no-reflow during percutaneous conranary intervention (PCI) often results in the failure of ischemic myocardial reperfusion and major adverse cardiovascular events (MACE). The present study sought to evaluate whether the GRACE risk score can predict coronary no-reflow in STEMI patients undergoing PCI. 【Methods】 We consecutively recruited 1 118 patients with STEMI who were admitted to Gansu Provincial People’s Hospital and The First Affiliated Hospital of Xi’an Jiaotong University from January 2009 to December 2011. Main demographic data, cardiovascular risk factors, blood lipid and other biochemical indicators were recorded. Coronary angiography was performed by a radial artery approach using the standard Judkins technique. Coronary no-reflow was evaluated by at least two independent experienced cardiologists. The GRACE risk score was calculated with a computer program. All the cases were followed up by medical records, face-to-face interviews or telephone calls. Finally, we analyzed the predictive value of the GRACE risk score for coronary non-reflow and MACE in STEMI patients undergoing PCI. 【Results】 During a median period of 36 months, 58 of the 1 118 patients (5.2%) were lost to follow-up. Of the remaining 1 060 patients, 118 (11.1%) had no-reflow and 147 (13.9%) had MACE. The GRACE score was higher in patients with no-reflow than those without no-reflow. Multivariate logistic regression established that the GRACE score was an independent predictor for coronary no-reflow (OR=1.034; P=0.002). And multivariate Cox analysis showed the GRACE score was an independent predictor of MACE. The area under the ROC curve for coronary no-reflow and MACE was 0.719 and 0.697, respectively. Kaplan-Meier analysis showed that the probability of rehospitalization for heart failure, reinfarction, all-cause death and cumulative cardiovascular events increased with the increase of the GRACE risk score. 【Conclusion】 The GRACE risk score is a readily available predictive scoring system for coronary no-reflow and MACE in STEMI patients.

Objective:To investigate the relationship between prolonged PR interval and carotid atherosclerosis(CAS)in middle-aged and elderly patients with type 2 diabetes mellitus(T2DM).Methods:A total of 537 middle-aged and elderly inpatients with T2DM in the Southern Branch of the Sixth People′s Hospital of Shanghai Jiaotong University from January 2019 to January 2021 were selected as the research objects. Color Doppler ultrasound was used to detect bilateral carotid artery intima-media thickness(CIMT). The subjects were divided into carotid atherosclerosis group(CAS group, n=352)and non-carotid atherosclerosis group(NCAS group, n=185). The difference in the PR interval of ECG between the two groups was compared. Pearson or Spearman rank correlation analysis was used for evaluating the correlation of PR interval and CAS lesions with various clinical index. The relationship between PR interval and CAS lesions was adopted by multivariate logistic regression analysis. Results:The average PR interval of middle-aged and elderly patients with T2DM was(164.57±23.02)ms. The average PR interval in CAS group was significantly higher than that in NCAS group [(169.76±24.28) vs (154.70±16.42)ms, P<0.01]. The results of multifactorial logistic regression analysis showed that age, low density lipoprotein-cholesterol, serum osteocalcin, and PR interval were independent factors influencing the development of CAS lesions in middle-aged and elderly patients with T2DM( OR=1.079, 1.936, 0.879, 1.039, respectively, P<0.05 or P<0.01)where each 1 ms increase in PR interval was associated with a 3.9% increase in the risk of CAS in middle-aged and elderly patients with T2DM( OR=1.039, 95% CI 1.006-1.073, P=0.020). Multivariate logistic regression analysis showed that middle-aged and elderly type 2 diabetic patients with PR interval≥158 ms were 4.072 times more likely to have CAS lesions than those with PR interval<158 ms( OR=4.072, 95% CI 1.417-11.702, P<0.01). Conclusion:The PR interval of electrocardiogram is correlated with CAS lesions in middle-aged and elderly patients with T2DM. Middle-aged and elderly type 2 diabetic patients with significantly prolonged PR interval should be reminded to screen for CAS lesions early.

Acetaminophen (APAP) overdose is the leading cause of drug-induced liver injury, and its prognosis depends on the balance between hepatocyte death and regeneration. Sirtuin 6 (SIRT6) has been reported to protect against oxidative stress-associated DNA damage. But whether SIRT6 regulates APAP-induced hepatotoxicity remains unclear. In this study, the protein expression of nuclear and total SIRT6 was up-regulated in mice liver at 6 and 48 h following APAP treatment, respectively.

Pyroptosis is a form of new programmed cell death which is dependent on Caspase-1 in recent years.When it' s stimulated by various dangerous signals from hepatic ischemia-reperfusion injury,the intracellular pattern recognition receptors are assembled into inflammasomes and Caspase-1 which was transformed into active form.Activated Caspase-1 promotes the maturation and secretion of pro-inflammatory cytokines IL-1β and IL-18,initiates the innate immunity rapidly and then induces severe inflammatory reaction.In addition,Caspase-1 can also cleave Gasdermin D and release its N-terminal domain triggering pyroptosis.Many studies showed that pyroptosis play a crucial role in hepatic ischemia-reperfusion injury.In this review,we discussed the activation mechanism and research progress of pyroptosis in hepatic ischemia-reperfusion injury.

Objective To examine the effect of the inter-stimulus interval (ISI) in magnetic stimulation (MS) on astrocyte migration and its related mechanism.Methods Cultured astrocytes were treated with intermittent MS with intervals of 1,5 and 10 seconds.The PEA-15 inhibitor BisI (10 μmol/ml) and the ERK1/2 inhibitor U0126 (10 μmol/ml) were administered and cell migration assays evaluated the astrocytes' migration.The expression of phosphorylated ERK1/2 and PEA-15 was detected using Western blotting.Results The 1 second interval significantly facilitated astrocyte migration,the phosphorylation of PEA-15 and ERK1/2,and the expression of MMP-9 (browse matrix metalloproteinase-9).The addition of Bis I significantly reduced the production of phosphorylated ERK1/2 and MMP-9,as well as astrocyte migration induced by MS.In addition,pretreatment with U0126 also significantly decreased the astrocyte migration induced by MS.Conclusion 1s-ISI MS can induce PEA-15 activation and subsequently lead to ERK1/2 phosphorylation and upregulation of MMP-9,which may contribute to the migration of astrocytes.
