RESUMEN
ObjectiveTo explore the risk factors of stroke， and to provide reference for the prevention and health management of stroke. MethodsFrom February 2022 to March 2022， four community residents over 60 years old with stroke in Shanghai were randomly selected as the case group （n=100）， and non-stroke residents were selected as the control group （n=100）. The survey was in the form of questionnaires to record and compare the age， body mass index （BMI）， blood lipids， blood pressure-related indicators， family history of other diseases， living habits， mood and sleep conditions of all subjects. The value of predicting the incidence of stroke among the elderly in Shanghai community was analyzed by receiver operating characteristic （ROC）， and the influencing factors of stroke were analyzed by logistic model. ResultsBMI， hypertension， heart disease， diabetes， transient ischemic attack （TIA）， dyslipidemia， family history of stroke， smoking， lack of exercise or only light physical labor， SBP， DBP， TG levels were significantly higher in the case group （P<0.05）. The level of HDL-C was significantly lower than that in the control group （P<0.05）. BMI， SBP， DBP， TG， HDL-C predicted the incidence of stroke by ROC analysis （P<0.05）. Logistic regression analysis showed that BMI≥23.820 kg·m-2， heart disease， diabetes， TIA， dyslipidemia， family history of stroke， smoking， lack of exercise or only light physical labor， SBP≥139.535 mmHg， DBP≥89.605 mmHg， TG≥1.565 mmol·L-1 and HDL-C≤1.105 mmol·L-1 were risk factors for stroke （P<0.05）. ConclusionPhysical health status including blood lipids and blood pressure， family history of certain diseases， and living habits could be important risk factors for stroke in the elderly in Shanghai community. Preventive intervention measures for the above factors have important clinical significance.
RESUMEN
Objective:To explore the characteristics of cognitive function in patients with early onset and adult onset schizophrenia.Methods:In this cross-sectional study, 546 patients with schizophrenia who met the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-Ⅳ) were selected.Among them, 62 cases were defined as early onset schizophrenia (EOS, age of onset＜18 years) and 175 patients were defined as adult onset schizophrenia (AOS, age of onset≥25 years).Patients underwent clinical assessments with the Positive and Negative Symptom Scale (PANSS) and the Personal and Social Performance Scale (PSP), and comprehensive neuropsychological assessments.Results:The EOS patients got lower scores in motor function-PEGDOM T score [ (26±12) vs. (30±11), P＜0.01], working memory-average T score of PASAT and WMSSP[ (34±12) vs. (38±10), P＜0.05]and executive function (inhibition) -Stroop T score [ (35±12) vs. (39±10), P＜0.05]than AOS patients.No differences were fund in processing speed, verbal memory and learning, visual memory and learning (Ps＞0.05) between the two groups.Conclusion:It suggests that the EOS patients have worse motor function, working memory and inhibition.
RESUMEN
When senescence induction is based on DNA damage, senescent cells display a unique phenotype, which has been termed “senescence-associated secretory phenotype”( SASP ) . SASP, including proinflammatory cytokines, growth factors, chemokines, matrix remodeling enzymes and other cytokines, may be an important driver of chronic inflammation and therefore may be part of a vicious cycle of inflammation, DNA damage and senescence. Senescence-associated secretory products released by such cells can affect the neighboring cells and further exacer-bate their regenerative capacity. SASP is associated with many chronic age-related diseases.
RESUMEN
Non-coding RNAs ( ncRNA ), including ribosomal RNA( rRNA), transfer RNA( tRNA), MicroRNA ( miRNA), long noncoding RNA(lncRNA) and small nucleolar RNA(snoR-NA), are a class of RNA that have multiple functions and are not translated to proteins. MicroRNA and lncRNA are involved in the injury, remodeling and aging of blood vessels, and it is necessary to understand the regulatory roles of MicroRNA and lncRNA in these processes. It is reported that MicroRNA and lncRNA are not only participated in the regulation of oxidative response, inflammation, cell proliferation and migration, and phenotype transition, they are also involved in the regulation of gene expression by conducting different mechanisms, including transcriptional regulation, post-transcriptional modification and chromatin remodeling. These aspects of regulation by MicroRNA and lncRNA are related to cardiovascular diseases, such as ath-erosclerosis, hypertension, myocardial infarction, stroke, pul-monary hypertension and diabetes, and thus provide a new way for genetic diagnosis and therapy of cardiovascular diseases.
