ObjectiveThis paper used the AGREE Ⅱ guideline evaluation tool to evaluate the quality of 14 clinical guidelines for acute myocardial infarction，aiming to provide reference for the formulation and improvement of the guidelines. MethodsClinical guidelines and expert consensus related to acute myocardial infarction were searched by web search. The search period ranges from January 1，2019 to November 1，2024 in CNKI，VIP，Wanfang Data，SinoMed，Web of Science，OVID， the International Guidelines Collaboration Network （GIN），the UK National Institute for Health and Clinical Excellence （NICE），Yimaitong， and other platforms. Three researchers independently screened the literature and used AGREE Ⅱ to score the screening results. After ensuring that the researchers have a consistent understanding of each guideline，the quality of the guidelines was evaluated. After that，the ratings were analyzed by layer according to the issuing agency，category，method of formulation，and funding situation and compared longitudinally by rating time. The clinical guidelines and expert consensus were compared in terms of content and evidence. ResultsA total of 14 guidelines and consensus were included. The results of AGREE Ⅱ in the six areas in descending order were scope and purpose （62.82%±10.43%），rigor （62.40%±12.77%），editorial independence （62.11%±22.26%），participants （61.42%±11.65%），clarity of expression （59.98%±9.62%），and application （52.94%±16.90%） . Eleven of the guidelines were at level B， and three were at level A. In the stratified analysis，the score of the guideline formulated by the Chinese Medical Doctor Association was lower. There was little difference between the scores of Chinese/Western and Western medicine guidelines. The average score of the guidelines was higher than the consensus. Funded guidelines and consensus scores were higher. In the longitudinal comparison，the highest number of guidelines were developed in 2020 and 2021，while those developed in 2023 scored the highest. In the differential comparison analysis，the content of the guidelines was more comprehensive， and the evidence level was higher，while the content of the consensus was more novel， and the evidence was less. ConclusionThe AGREE Ⅱ score of the clinical guidelines for acute myocardial infarction is generally moderate，and there is room for improvement in terms of applicability. At the same time，the content quality of expert consensus should be improved，and more efforts should be made to develop and apply Chinese medicine guidelines for complications such as heart failure and microcirculatory obstruction after acute myocardial infarction.

Objective To analyze the monitoring data of cardio-cerebrovascular diseases prevention and control system in Yichang in 2022, and to provide data support and experience for the precise prevention and treatment of cardio-cerebrovascular diseases. Methods Acute cardiovascular and cerebrovascular event data were collected from the Yichang Cardio-cerebrovascular Events Monitoring System from January 1, 2022 to December 31, 2022. Descriptive analysis was conducted for the data collected. Statistical analysis was performed using SPSS 20.0 software, and a chi-square test was used to analyze the count data. Results A total of 37,217 cases of cardio-cerebrovascular events were monitored in Yichang in 2022. The crude incidence and the standardized incidence were 983.84/100,000 and 541.55/100,000, respectively. The incidence in males was higher than females (554.93/100,000 vs 428.91/100,000，χ² =464.52，P＜0.05). The top three diseases were cerebral infarction, acute myocardial infarction, and cerebral hemorrhage. The incidence of events increased with age, and 79.80% of the cases were over 60 years old. The main onset time was from May to August. Conclusion The use of the cardio-cerebrovascular events monitoring system in Yichang and the implementation of ^“mandatory reporting card^” monitoring can timely obtain the epidemic characteristics of the diseases, provide support for the precise formulation of prevention and control strategies and measures, reduce underreporting rates, and improve the monitoring system, which is worthy of reference and promotion.

Objective:To explore the inhibitory effect of long non-coding RNA (lncRNA) KCNQ1 overlapping transcript 1 (KCNQ1OT1) by targeting microRNA-199a-5p (miR-199a-5p) on the apoptosis of human lens epithelial cells (LECs).Methods:The anterior lens capsule tissue of 23 age-related cataract patients who underwent cataract surgery in Xinxiang First People's Hospital from December 2018 to August 2019 was collected.At the same time, anterior lens capsules from 20 healthy donor were collected.The expressions of KCNQ1OT1 and miR-199a-5p in the tissues were detected by real-time fluorescence PCR.Human LECs SRA01/04 cultured in vitro were divided into blank control group, model control group, small interfering RNA-negative control (siR-NC) group, siR-KCNQ1OT1 group, miR-NC group, miR-199a-5p group, siR-KCNQ1OT1+ anti-miR-NC group and siR-KCNQ1OT1+ anti-miR-199a-5p group.No intervention was administered to blank control group.Cells in model control group were cultured with 100 μmol/L H 2O 2 for 24 hours to establish oxidative stress injured model, and cells in the other six groups were transfected with corresponding transfection reagents for 6 hours by liposome method according to grouping, and then treated with 100 μmol/L H 2O 2 for 24 hours.The expressions of KCNQ1OT1 and miR-199a-5p in lens anterior capsule tissue and LECs cells were determined by real-time fluorescent quantitative PCR.Cell viability was detected with thiazolyl blue (MTT). Cell apoptosis was analyzed by flow cytometry.The expressions of B-cell lymphoma/leukemia-2 (bcl-2) and bcl-2 related X protein (Bax) proteins were assayed by Western blot.The superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were measured by enzyme-linked immunosorbent assay (ELISA). The targeting relationship between KCNQ1OT1 and miR-199a-5p was verified by dual luciferase reporter experiment.The study protocol was approved by an Ethics Committee of Xinxiang First People's Hospital (No.2019-001). Written informed consent was obtained from relatives of patient. Results:The relative expression of KCNQ1OT1 in the anterior capsule of patients with age-related cataract was 2.41±0.42, which was significantly higher than 0.97±0.19 of normal people, and the relative expression of miR-199a-5p in the capsule of patients with age-related cataract was 0.36±0.12, which was lower than 1.04±0.15 of normal people, and the differences were statistically significant ( t=14.112, 16.507; both at P<0.001). Compared with blank control group, the relative expressions of KCNQ1OT1 and bax protein, cell apoptosis rate and MDA content were significantly increased, and the relative expressions of miR-199a-5p and bcl-2 protein, cell viability and SOD activity were significantly reduced in model control group, showing statistically significant differences (all at P<0.001). Compared with siR-NC group, the relative expressions of KCNQ1OT1 and bax protein, cell apoptosis rate and MDA content in cells of siR-KCNQ1OT1 group were decreased, while the relative expression of bcl-2 protein, cell survival rate and SOD activity were increased, and the differences were statistically significant (all at P<0.05). Compared with miR-NC group, the KCNQ1OT1-wild type (WT) luciferase activity in miR-199a-5p group was significantly decreased, with a statistically significant difference ( t=21.131, P<0.001). The relative expression levels of miR-199a-5p and bcl-2 proteins, cell survival rate and SOD activity were significantly increased, and the relative expression of bax protein, cell apoptosis rate and MDA content were significantly decreased in miR-199a-5p group than those in miR-NC group, and the differences were statistically significant (all at P<0.05). The relative expression levels of miR-199a-5p and bcl-2 proteins, cell survival rate and SOD activity were significantly lower, and the cell apoptosis rate, relative expression of bax protein and MDA content were significantly higher in siR-KCNQ1OT1+ anti-miR-199a-5p group than those in siR-KCNQ1OT1+ anti-miR-NC group, and the differences were statistically significant (all at P<0.05). Conclusions:The inhibition of KCNQ1OT1 can promote the cell viability of human LECs, inhibit H 2O 2-induced cell apoptosis and oxidative stress, and the mechanism may be related to the up-regulation of miR-199a-5p.
