ABSTRACT

@#Skeletal angle class Ⅲ malocclusion with mandibular deviation involves the rotation and translation of the cranial base, maxilla, mandible, and soft tissue. It compromises the patients’ appearance and stomatognathic function. The treatment outcome is not satisfactory, and correct evaluation is of great significance. The causal relationship between skeletal Class Ⅲ with mandibular deviation and TMD remains controversial. This review focuses on the structural alterations of hard and soft tissue, the etiology, the choice of treatment methods, and the association with TMD in patients with skeletal class Ⅲ malocclusion with mandibular deviation. The results show that mandibular deviation is a complex disease with unclear etiology. It involves morphological changes, rotation and displacement of the cranial base, maxilla and mandible, morphological changes of the soft tissue, and occlusal changes, which also compromise the temporomandibular joint and mandibular function. Skeletal Class Ⅲ malocclusion is common in patients with mandibular deviation. Early treatment is needed; however, the treatment methods vary. The correct evaluation of the morphological changes of soft and hard tissues leading to facial asymmetry is the premise of treatment. Orthodontic and orthognathic treatment (combined with soft tissue repair when necessary) is an effective method for the treatment of skeletal class Ⅲ malocclusion with mandibular deviation. In addition, there is a close relationship between mandibular deviation and TMD, which needs to be fully considered in the design of treatment.

ABSTRACT

Resumo Fundamento A dupla antiagregação plaquetária (DAP) é o tratamento fundamental do infarto agudo do miocárdio (IAM). Objetivo O presente estudo visou investigar a eficácia e a segurança da tripla antiagregação plaquetária (TAP) em pacientes femininas idosas com diabetes e infarto agudo do miocárdio com supradesnível do segmento ST (IAMCSST), que foram submetidas à intervenção coronária percutânea ICP. Métodos Trata-se se de um estudo randomizado e mono-cego. O grupo controle A (97 pacientes idosos do sexo masculino com diabetes e STEMI, cujos escores CRUSADE foram < 30) recebeu aspirina, ticagrelor e tirofibana. Um total de 162 pacientes femininas idosas com diabetes e IAMCSST foram divididas aleatoriamente em dois grupos de acordo com o escore CRUSADE. O grupo B (69 pacientes com escore CRUSADE > 31) recebeu aspirina e ticagrelor. O grupo C (93 pacientes com escore CRUSADE < 30) recebeu aspirina, ticagrelor e tirofibana. Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados Após a PCI, o fluxo sanguíneo grau 3 Thrombolysis in Myocardial Infarction (TIMI) e a perfusão miocárdica TIMI grau 3 foram significativamente menos prevalentes no grupo B, em comparação com o grupo A (p < 0,05). Quando comparada aos grupos A e C, a incidência de complicações adversas maiores foi significativamente maior no grupo B (p < 0,05). Conclusão A TAP pode efetivamente reduzir a incidência de complicações maiores em pacientes idosas com diabetes e IAMCSST. No entanto, atenção cuidadosa deve ser dada à hemorragia em pacientes que recebem TAP. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)


Abstract Background Dual antiplatelet therapy (DAPT) is the cornerstone treatment of acute myocardial infarction (AMI). Objective The present study aimed to investigate the efficacy and safety of triple antiplatelet therapy (TAPT) in elderly female patients with diabetes and ST segment elevation myocardial infarction (STEMI), who had undergone percutaneous coronary intervention (PCI). Methods We designed a randomized, single-blind study. Control group A (97 elderly male patients with diabetes and STEMI, whose CRUSADE scores were < 30) received aspirin, ticagrelor, and tirofiban. A total of 162 elderly female patients with diabetes and STEMI were randomly divided into two groups according to CRUSADE score. Group B (69 patients with CRUSADE score > 31) received aspirin and ticagrelor. Group C (93 patients with CRUSADE score < 30) received aspirin, ticagrelor and tirofiban. P values < 0.05 were considered statistically significant. Results Compared to the findings in group A, post-PCI Thrombolysis in Myocardial Infarction (TIMI) grade 3 blood flow and TIMI myocardial perfusion grade 3 were significantly less prevalent in group B (p < 0.05). When compared to groups A and C, the incidence of major adverse complications was significantly higher in group B (p < 0.05). Conclusion TAPT could effectively reduce the incidence of major complications in elderly female patients with diabetes and STEMI. However, close attention should be paid to hemorrhage in patients receiving TAPT. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

ABSTRACT

Objective To investigate the epidemiology of echinococcosis in Serthar County, Sichuan Province, so as to provide insights into optimization of echinococcosis control measures. Methods The prevalence of human echinococcosis was surveyed among permanent residents living in Serthar County at ages of over 2 years from 2016 to 2019, and the prevalence of Echinococcus infections was surveyed in owned dogs, yaks and rodents in 2019. The epidemiological features of echinococcosis in humans and animals were descriptively analyzed. Results The overall prevalence of human echinococcosis was 3.72% (1 613/43 362) in Serthar County from 2016 to 2019, and the prevalence rates of cystic echinococcosis, alveolar echinococcosis and mixed infections of cystic echinococcosis and alveolar echinococcosis were 1.72% (745/43 362), 1.98% (860/43 362) and 0.02% (8/43 362), respectively. The prevalence of human echinococcosis was higher in pastoral areas (4.13%, 1 577/38 149) than in semi-agricultural and semi-pastoral areas (0.69%, 36/5 213) (χ2 = 151.82, P < 0.05); however, there was no significant difference in the prevalence between men (3.76%, 819/21 787) and women (3.68%, 794/21 575) (χ2 = 0.19, P > 0.05). Cystic echinococcosis was the predominant type in students with echinococcosis (93.78%, 422/450), while alveolar echinococcosis was the predominant type in herders with echinococcosis (72.16%, 801/1 110). There was a significant difference in the constituent ratio of echinococcosis types between students and herders (χ2 = 588.57, P < 0.05). In addition, higher prevalence of echinococcosis was detected in nomadic populations (4.58%, 1 008/22 021) than in community-dwelling populations (2.83%, 605/21 341) (χ2 = 91.88, P < 0.05). The Echinococcus copro-antigen-positive rate was 0.19% (4/2 157) in owned dogs, and the detection rate of echinococcosis was 8.00% (16/200) in yaks and 3.10% (31/1 000) in rodents in 2019. Conclusions Echinococcosis is highly prevalent in Serthar County, Sichuan Province. Sustained management of source of Echinococcus infections, improved treatment of echinococcosis patients and timely health education for nomadic populations are recommended.

ABSTRACT

Macular edema is an important cause of visual impairment in many eye diseases such as diabetic retinopathy, retinal vein occlusion and uveitis. Optical coherence tomography (OCT) provides high-resolution image of retinal microstructures in a non-contact and rapid manner, which greatly improves the ability of diagnosis and follow-up to macular edema patients. OCT has been widely used in the clinical detection of patients with macular edema. No matter what the cause of macular edema is, it can be observed in OCT images that there are spot-like deposits with strong reflection signals in the retina, which are mostly distributed discretely or partially convergent, and are called hyperreflective foci. At present, the nature or source of hyperreflective foci is not clear, however, may involve the destruction of the blood retina barrier, retinal inflammatory reaction, neurocellular degeneration, and so on. These mechanisms are also the key physiological mechanisms in the development of macular edema. The clinical research on hyperreflective foci provides a new direction for understanding the pathogenesis of macular edema and predicting the prognosis of macular edema. The distribution and quantity characteristics of hyperreflective foci may be an important biological marker to predict the prognosis of macular edema.nosis of macular edema. foci provides a new direction for understanding the pathogenesis of macular edema and predicting the prognosis of macular edema. The distribution and quantity characteristics of HRF may be an important biological marker to predict the prognosis of macular edema.

ABSTRACT

Objective:To investigate the effect of heme oxygenase-1 (HO-1) modified rat bone marrow mesenchymal stem cells (BMSCs) on fibrotic rats.Methods:110 male SD rats aged 6-8 weeks were selected randomly divided into model group, BMSCs group and HO-1/BMSCs group with 11 rats in each group after intraperitoneal injection of CCl 4, PBS, BMSCs and HO-1/BMSCs were injected respectively. Another 11 rats were selected as control group. After 4 weeks of intervention, tracer experiment was used to detect the location of BMSCs. Rats in each group were executed, and liver function were detected by biochemical analyzer, liver fibrosis indexes were detected by ELISA, liver histopathology were detected by HE and Sirius red staining. Immunohistochemistry, Western blot and RT-PCR were used to detect the protein and mRNA expression of E-cadherin and Vimentin. Results:The rat fibrosis model was successfully established. Tracer experiment showed that BMSCs were implanted in rat liver after transplantation. Compared with the model group, the liver function and liver fibrosis indexes of BMSCs group and HO-1/BMSCs group were improved, and Ishak score and stage were significantly decreased, and HO-1/BMSCs group was superior to BMSCs group. The expression of E-cadherin in HO-1/BMSCs group (0.92±0.21), (0.84±0.03) were higher than those in BMSCs group [(0.54±0.16), (0.53±0.04)] and model group [(0.49±0.06), (0.11±0.06)] both at protein and mRNA level, while protein and mRNA level of Vimentin (1.21±0.23), (3.82±0.80) were lower than that in BMSCs group [(1.32±0.17), (6.39±0.75)] and model group [(1.41±0.18), (16.94±1.30)]. The difference was statistically significant ( P<0.05). Conclusion:HO-1/BMSCs can improve liver function and liver fibrosis in fibrotic rats more effectively than BMSCs alone. The mechanism was possibly through inhibiting liver epithelial mesenchymal transition.

ABSTRACT

Adalimumab, one of the tumor necrosis factor-α (TNF-α) inhibitors, has been approved as a therapeutic drug for non-infectious intermediate, posterior and pan-uveitis by FDA.Due to the good efficacy, TNF-α inhibitors are being applied widely in ophthalmology.However, some researches based on the application of TNF-α inhibitor in treating inflammatory bowel diseases and rheumatoid arthritis, etc.have showed that it can bring out some adverse effects such as infection and tumor occurrence and/or progression.The main safety problems in the application of TNF-α inhibitors lie in its increased risk of serious infection, postoperative infection, the occurrence or progression of tuberculosis and hepatitis, as well as the tumorigenesis and tumor progression.With the wider application of adalimumab in refractory uveitis, ophthalmologists should not only focus on its therapeutic effect, but also get to know the adverse effects of the drug, so as to standardize the examination, prevention and control of primary diseases before and after the administration of adalimumab and observe closely clinical manifestations of patients with administration of adalimumab, select the treating method and timing reasonably to reduce and avoid the adverse drug reactions, and improve the therapeutic outcome.

ABSTRACT

Objective:To investigate the protective effect of baicalein on injured PC12 cell induced by Aβ and explore its mechanism.Methods:The method of MTT was used to detect the cell activity of each group and screened the concentration of baicalein. The PC12 cells were randomly divided into the blank group, the Aβ group, the baicalin group and the estradiol group. 24 hours after inoculation, baicalein group was intervened with 1×10 -6 mol/L baicalein solution, and estradiol group was intervened with 1×10 -5 mol/L estradiol solution. Two hours later, except the blank group, the other groups were added with 1.5×10 -4 mol/L Aβ to make the model. MTT assay was used to detect the cell viability of each group after 24 hours of cultivation. Then used oxidation kit to detect the contents of superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and lactate dehydrogenase (LDH) in each group. And the level of caspase-3 mRNA was detected by Real-time Quantitative PCR (RT-PCR). Then the Western blot method was used to detect the expressions of p-PI3K, p-AKT and caspase-3. Results:Compared with the Aβ group, the PC12 cell viability [(96.348 ± 0.571)%, (97.183 ± 0.714)% vs. (86.922 ± 0.429)%] in the baicalin group and the estradiol group significantly increased( P<0.01). The activities of SOD [(54.31 ± 1.34) U/mgprot, (57.38 ± 2.25) U/mgprot vs. (36.18 ± 2.24) U/mgprot] and GSH-PX [(4.46 ± 0.23) U/mgprot, (4.72 ± 0.31) U/mgprot vs. (2.05 ± 0.37) U/mgprot] significantly increased, and the level of LDH [(85.43 ± 0.92) nmol/ml, (82.46 ± 0.27) nmol/ml vs. (99.17 ± 0.52) nmol/ml] significantly decreased ( P<0.01). The expression of caspase-3 mRNA (2.24 ± 0.64, 2.33 ± 0.75 vs. 3.46 ± 0.46) and p-PI3K (0.46 ± 0.03, 0.44 ± 0.06 vs. 0.66 ± 0.09), p-AKT (0.43 ± 0.05, 0.41 ± 0.02 vs. 0.58 ± 0.03), caspase-3 (0.61 ± 0.03, 0.56 ± 0.53 vs. 0.92 ± 0.07) protein significantly decreased ( P<0.01). Conclusion:Baicalein could slow down cell apoptosis and oxidative reaction, reduce the damage of Aβ to PC12 cells by inhibiting the expression of PI3K/AKT pathway.

ABSTRACT

Abstract@#Overweight and obesity among children is not only harmful to physical and mental health, but also associated with an increased risk of chronic diseases such as hypertension and diabetes in adulthood. Health related behavioral factors are one of the most important causes of child overweight and obesity, which commonly co occur and show a synergistic negative influence on health. The synergistic effects suggest that interventions are likely to be more cost effective and to maximize impact by targeting health risk behaviors in combination with the improvement of a variety of modificable behaviors. The present review aims to describe the update of co occurrence and clustering patterns of obesity related health risk behaviors, and proposes the future direction for prevention and control of overweight and obesity in children.

ABSTRACT

Objective:To explore the key gens of peripheral blood mononuclear cells in hepatocellular carcinoma(HCC-PBMC) and potentially effective Chinese herbs based on bioinformatics, and to verify the clinical efficacy of these Chinese herbs via a systematic review. Method:The chips GSE58208 and GSE36076 of HCC-PBMC were downloaded from the Gene Expression Omnibus (GEO), followed by the identification of differentially expressed genes (DEGs) using RStudio. After protein-protein interaction (PPI) analysis by STRING, the DAVID was employed for gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The DEGs of HCC-PBMC were visualized by Cytoscape. The key genes of HCC-PBMC were calculated by CytoHubba plug-in and mapped with those in Coremine Medical for screening out the potential Chinese herbs for the treatment of HCC, which were then included for subsequent systematic review. Result:A total of 203 DEGs were obtained (194 up-regulated and nine down-regulated). As revealed by DAVID analysis, the DEGs were mainly enriched in such biological processes and signaling pathways as transcriptional regulation of DNA template, hydrolysis of ribonucleic acid phosphodiester bond, positive regulation of intranuclear mitosis and division, skeletal muscle fiber development, activation of mitogen-activated protein kinase(MAPK)activity, Fanconi anemia pathway, and metabolic pathway. The key genes of HCC-PBMC were calculated by Cytoscape to be<italic> </italic>GTPase IMAP family member 1 (GIMAP1), GTPase IMAP family member 4 (GIMAP4), GTPase IMAP family member 6 (GIMAP6), GTPase IMAP family member 7 (GIMAP7), GTPase IMAP family member 8 (GIMAP8), interleukin-1<italic>β </italic>(IL-1<italic>β)</italic>, CX3C chemokine receptor 1 (CX3CR1), C-C chemokine receptor type 2 (CCR2), Toll-like receptor 7(TLR7), and epidermal growth factor(EGF). Through Coremine Medical analysis, it was concluded that Ginseng Radix et Rhizoma, Curcumae Longae Rhizoma, Centellae Herba, and Hedyotidis Herba were closely related to the key genes. Ginseng Radix et Rhizoma has the effects of tonifying and benefiting lung and spleen and enhancing strength, suitable for the liver depression and spleen deficiency syndrome or Qi-Yin deficiency syndrome of HCC. Hence, Si Junzitang with Ginseng Radix et Rhizoma as the sovereign medicinal was included for systematic review. It has been confirmed that Ginseng Radix Et Rhizoma was superior to western medicine alone in improving the overall clinical efficacy, alleviating TCM syndrome, elevating serum CD4<sup>+ </sup>and CD4<sup>+</sup>/CD8<sup>+ </sup>levels, and reducing the serum CD8<sup>+ </sup>and TBIL levels (<italic>P</italic><0.01), with high safety. Conclusion:This study conducted at the gene level has provided new ideas for clinical diagnosis and treatment of HCC. The systematic review of Ginseng Radix Et Rhizoma against HCC provides a basis for the clinical prevention and treatment of HCC with TCM.

ABSTRACT

BACKGROUND@#Age-related macular degeneration (AMD) is the leading cause of vision loss worldwide. However, the mechanisms involved in the development and progression of AMD are poorly delineated. We aimed to explore the critical genes involved in the progression of AMD.@*METHODS@#The differentially expressed genes (DEGs) in AMD retinal pigment epithelial (RPE)/choroid tissues were identified using the microarray datasets GSE99248 and GSE125564, which were downloaded from the gene expression omnibus database. The overlapping DEGs from the two datasets were screened to identify DEG-related biological pathways using gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. The hub genes were identified from these DEGs through protein-protein interaction network analyses. The expression levels of hub genes were evaluated by quantitative real-time polymerase chain reaction following the induction of senescence in ARPE-19 with FK866. Following the identification of AMD-related key genes, the potential small molecule compounds targeting the key genes were predicted by PharmacoDB. Finally, a microRNA-gene interaction network was constructed.@*RESULTS@#Microarray analyses identified 174 DEGs in the AMD RPE compared to the healthy RPE samples. These DEGs were primarily enriched in the pathways involved in the regulation of DNA replication, cell cycle, and proteasome-mediated protein polyubiquitination. Among the top ten hub genes, HSP90AA1, CHEK1, PSMA4, PSMD4, and PSMD8 were upregulated in the senescent ARPE-19 cells. Additionally, the drugs targeting HSP90AA1, CHEK1, and PSMA4 were identified. We hypothesize that Hsa-miR-16-5p might target four out of the five key DEGs in the AMD RPE.@*CONCLUSIONS@#Based on our findings, HSP90AA1 is likely to be a central gene controlling the DNA replication and proteasome-mediated polyubiquitination during the RPE senescence observed in the progression of AMD. Targeting HSP90AA1, CHEK1, PSMA4, PSMD4, and/or PSMD8 genes through specific miRNAs or small molecules might potentially alleviate the progression of AMD through attenuating RPE senescence.

ABSTRACT

Objective@#To understand the prevalence of overweight and obesity, dietary habits and main food intake frequency among primary school students in Shenyang, so as to provide a reference for exploring the effect of diet related factors on the development of overweight and obesity in children.@*Methods@#A total of 2 041 students from two primary schools in a certain district of Shenyang were selected by convenience sampling in May 2017, with height and weight measured, meanwhile the questionnaire survey regarding dietary habits and the frequency of main food intake were administered.@*Results@#The rates of overweight and obesity were 18.4% and 22.1% respectively, and the rate of overweight and obesity in boys (21.0%,27.8%) were significantly higher than that in girls (15.8%,16.2%)(χ 2=22.45,53.40,P<0.01). The results of univariate analysis showed that frequency of eating breakfast, eating speed, appetite, picky eaters or not, and the frequency of fruit, seafood and canned food intake were associated with overweight and obesity in primary school students (χ 2=7.67,97.92,229.70,95.88,6.40,6.58,7.96,P<0.05). Multivariate Logistic regression analysis showed that slow eating speed (OR=0.46, 95%CI=0.29-0.69) and normal eating speed (OR=0.47, 95%CI=0.32-0.69) were associated with lower rates of overweight and obesity; good appetite (OR=43.73, 95%CI=5.88-325.36) was associated with higher rates of overweight and obesity in primary school students (P<0.01).@*Conclusion@#The detection rate of overweight and obesity is relatively high among primary school students in Shenyang, and the rate of obesity is already higher than that of overweight; The frequency of common food intake has little impact on the development of overweight and obesity in primary school students, but fast eating speed and good appetite are the risks of overweight and obesity among them.

ABSTRACT

Gastric cancer(GC), one of the most common malignancies worldwide, seriously threatens human health due to its high morbidity and mortality. Precancerous lesion of gastric cancer(PLGC) is a critical stage for preventing the occurrence of gastric cancer, and PLGC therapy has frequently been investigated in clinical research. Exploring the proper animal modeling methods is necessary since animal experiment acts as the main avenue of the research on GC treatment. At present, N-methyl-N'-nitro-N-nitroso-guanidine(MNNG) serves as a common chemical inducer for the rat model of GC and PLGC. In this study, MNNG-based methods for modeling PLGC rats in related papers were summarized, and the applications and effects of these methods were demonstrated by examples. Additionally, the advantages, disadvantages, and precautions of various modeling methods were briefly reviewed, and the experience of this research group in exploring modeling methods was shared. This study is expected to provide a reference for the establishment of MNNG-induced PLGC animal model, and a model support for the following studies on PLGC.

ABSTRACT

As a new type of intercellular signaling rector, extracellular vesicles (EV) are involved in almost the whole process of tumorigenesis, progression, metastasis, and drug resistance. Therefore, EV have become the ideal biomarker candidates and research hotspots for cancer diagnosis and treatment. However, EV tumor biomarker research mainly focused on RNA and protein, and a small part of the research focused on lipids at the early stage. EV DNA has received little attention and its diagnostic value has gradually been recognized in recent years. Study on the biological characteristics and function of EV DNA may highlight its potential in tumor diagnosis.

ABSTRACT

Objective:To explore the feasibility of artificial intelligence ultrasound to diagnose of biliary atresia (BA) based on deep learning.Methods:A total of 531 gallbladder ultrasound images in 177 cases of BA patients (BA group) and 585 gallbladder ultrasound images in 195 cases of Non-BA patients (Non-BA group) were collected in Hunan Children′s Hospital from September 2018 to October 2020. For the BA and Non-BA groups, all images were divided into training set and test set according to the ratio of 2∶1. The Mask R-CNN model was trained by training samples, and then the model was tested, according to patient and image as a unit respectively, to evaluate the gallbladder organ detection rate and the diagnostic accuracy of BA. In addition, the images of the test set were randomly numbered.Four sonographers were invited to interpret the images to calculate the diagnostic accuracy individually. Last, the diagnostic accuracy of the Mask R-CNN model was compared with that of sonographers.Results:In terms of the automatic detection of gallbladder organs, the detection rate in both BA and Non-BA group reached 100%, but there were 17 false alarms in 372 test images, with a false alarm rate of 4.57%. In terms of the diagnostic rate of gallbladders, when taking patient as a unit, the total diagnostic accuracy of the model in the test set was 95.97%, which was higher than that of the sonographers in other hospitals and the sonographer with intermediate professional title in our hospital, and the difference was statistically significant ( P<0.005). It was slightly higher than that of sonographer with senior professional title in our hospital (91.94%), but the difference was not statistically significant ( P=0.183). When taking picture as a unit, the total diagnostic accuracy of the model was 97.04%, which was higher than that of the sonographers in other hospitals and the sonographer with intermediate professional title in our hospital, and the difference was statistically significant ( P<0.001). It was slightly higher than that of sonographer with senior professional title in our hospital (94.09%), but the difference was not statistically significant ( P=0.05). Conclusions:The artificial intelligence technology based on Mask R-CNN can automatically and accurately detect gallbladder organs and diagnose BA, which is worthy of further study.

ABSTRACT

Abstract@#The visual health of children and adolescents in China has become a major issue that is relevant to the nation s present and its future. This article analyzed the value of map reading and searching for specific features during orienteering projects for myopia prevention and control. The findings suggest that orienteering exercises show good regulatory effects on eye muscles, effectively improve concentration, and help to stimulate mental activity and visual system. Targeted exercises, including scanning maps for specific features, is beneficial for myopia prevention and control. It is proposed that, by changing the teaching style of cross-country orienteering, teaching space, and teaching scene, exercises can be tailored to treat and relieve eye strain, as well as to prevent and control myopia, which is essential to promote the visual health of children and adolescents.

ABSTRACT

Objective@#To understand the trend of cardiovascular diseases death and disease burden caused by early death from 2009 to 2018 in Ningbo, so as to provide evidence for the prevention and control of cardiovascular disease.@*Methods@#The monitoring data of cardiovascular diseases death from 2009 to 2018 was collected from Ningbo death cause surveillance system. The mortality rate, early death probability, years of life lost ( YLL ) and working years of potential life lost ( WYPLL ) were calculated, and the mortality rate and YLL rate were standardized by 2010 national standard population. The annual percentage change ( APC ) was used to measure the time trend. @*Results@#From 2009 to 2018, there were 42 961 deaths from cardiovascular diseases in Ningbo, with a mortality rate of 7.35/104, a standardized mortality rate of 4.25/104, and an early death probability of 0.84%. The APC of cardiovascular disease mortality and standardized mortality were 57.488% and 6.004%, both showing an upward trend ( P<0.05 ); the APC of the probability of early death was -1.253%, showing a downward trend ( P<0.05 ). The male mortality rate was 4.16×104, which was lower than the female's 4.36/104 ( P<0.05 ). The YLL, standardized YLL rate, and WYPLL for cardiovascular diseases were 329 266.65 person-years, 3.82‰, and 18 355.63 person-years, respectively. The overall APC of YLL is 1.700%, showing an upward trend ( P<0.05 ). The standardized YLL rate of cardiovascular diseases increased with age ( P<0.05 ). with the APC of 1.503%. Ischemic heart disease and hypertensive heart disease were dominant, their YLLs were 105 949.75 and 46 015.68 person-years, respectively. @*Conclusion@#From 2009 to 2018, the mortality of cardiovascular diseases show an increasing trend, while the burden caused by early death in Ningbo reverses. Women and the elderly are high-risk groups, and ischemic heart disease and hypertensive heart disease are high-risk diseases.
