The escalating phenomenon of global population aging is posing multi-dimensional challenges to society, the economy and medical healthcare system.Among the significant health threats to the elderly population are cardiovascular diseases(CVD)and cognitive frailty(CF), both of which profoundly affect the quality of life and increase the risks of adverse health outcomes, including disability, hospitalization, and death.The concurrent presence of CVD and CF in elderly patients is prevalent, as these conditions share many common risk factors and underlying pathophysiological mechanisms, such as atherosclerosis, microcirculation dysfunction, and inflammation, which interact to perpetuate a vicious cycle.Notably, CF exhibits a certain degree of reversibility; thus, the implementation of a diagnosis and treatment paradigm that incorporates "comprehensive geriatric assessment and geriatric interdisciplinary teams" should be established as a conventional management strategy for elderly patients affected by both CVD and CF.Cognitive digital therapeutics, along with personalized exercise prescriptions based on cardiopulmonary exercise tests, may represent more appropriate precision interventions for these patients.Consequently, there is a necessity for further in-depth research in this area moving forward.

Migraine is a common neurological disorder with a complex pathogenesis that is currently not fully understood;however,the role of mitochondrial function in migraine pathogenesis has recently attracted widespread attention.This review considers the latest research progress on the relationship between mitochondrial dysfunction and migraine,including mitochondrial energy metabolism,oxidative stress,calcium homeostasis,and neuroinflammation.We introduce the epidemiological and clinical characteristics of migraine,and provide a detailed exploration of the key role of mitochondria in these processes.Mitochondrial dysfunction may lead to increased neuronal excitability,abnormal vasoconstriction,and inflammatory responses,thereby inducing migraine.Based on the evidence of mitochondrial involvement in the pathogenesis of migraine,we propose future research directions and potential treatment strategies,with the aim of providing new ideas for the prevention and treatment of migraine.

BACKGROUND:Current studies have shown that electronic moxibustion can improve memory function in amnestic mild cognitive impairment;however,its mechanism of action needs to be further investigated.The atrophy of hippocampal volume and impairment of functional connectivity are important imaging markers of amnestic mild cognitive impairment.Whether electronic moxibustion can regulate the volume of hippocampal subregion of partients with amnestic mild cognitive impairment is worth studying. OBJECTIVE:To observe the effect of electronic moxibustion on the volume of hippocampal subregions in patients with amnestic mild cognitive impairment. METHODS:Forty patients with amnestic mild cognitive impairment were recruited from April 1,2018 to January 31,2019 at the community service centers around the Second Affiliated Hospital of Shenzhen University(Baoan Hospital of Southern Medical University),Shenzhen,China.They were randomly divided into treatment group(n=20)and control group(n=20).The treatment group was treated with electronic moxibustion of regulating the mind and benefiting the intelligence,while the control group was treated with placebo moxibustion.Moxibustion was given at 45 oC,20 minutes each time,once a day,5 times a week,for 8 weeks in total.Memory evaluation using Rivermead behavioral memory test and magnetic resonance imaging scanning for detecting the hippocampal subregion volume were performed for each patient before and after treatment,and cognitive function of each patient was assessed using Montreal cognitive assessment and mini-mental state examination.Correlation of hippocampal subregion volumes with scores on each scale was analyzed. RESULTS AND CONCLUSION:After treatment,the volumes of the left parasubiculum and the left hippocampal-amygdala migrating area increased in the treatment group but decreased in the control group,and there was a significant difference between the two groups(P＜0.05).Compared with the pre-treatment data,the Rivermead behavioral memory test,Montreal cognitive assessment,and mini-mental state examination scores were significantly higher in the treatment group after treatment(P＜0.05),while there was no significant change in the three scale scores in the control group after treatment(P＞0.05).The three scale scores were higher in the treatment group than in the control group after treatment(P＜0.05).Pearson correlation analysis showed that the changes in the volume of the left parasubiculum was significantly and positively correlated with the Rivermead behavioral memory test scale score in the treatment group(r=0.418,P=0.014).To conclude,electronic moxibustion can improve memory in patients with amnestic mild cognitive impairment,and the mechanism may be the regulation of structural plasticity in hippocampal subregions.

ObjectiveTo explore the clinical efficacy and safety of Qifu Yixin prescription in treating chronic heart failure in the patients with the syndrome of heart Qi deficiency， so as to provide clinical evidence for the treatment of chronic heart failure with this prescription and promote the clinical application and transformation of this prescription. MethodA total of 106 chronic heart failure patients with the syndrome of heart Qi deficiency who met the criteria in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine （TCM） from September 2022 to May 2023 were selected and randomized into an observation group （53 cases） and a control group （53 cases）. Both groups received routine Western medicine treatment. In addition， the observation group received Qifu Yixin prescription， while the control group received placebo. The treatment course for both groups was 12 weeks. The New York heart association （NYHA） cardiac function grading， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， soluble growth-stimulating expression gene 2 （sST2）， left ventricular ejection fraction （LVEF）， the ratio of early diastolic maximum mitral flow velocity （E） to early diastolic mitral annular motion velocity （e'） （E/e'）， left ventricular end diastolic diameter （LVEDD）， TCM syndrome scores， 6-minute walking test （6MWT）， Minnesota Living with Heart Failure Questionnaire （MLHFQ）， and Kansas City Cardiomyopathy Questionnaire （KCCQ） were determined before and after treatment. ResultFinally， 102 patients were included for analysis， including 51 patients in the observation group and 51 patients in the control group. After treatment， 42 patients in the observation group showed improved cardiac function grading， with a total response rate of 82.35%， and 32 patients in the control group showed improved cardiac function grading， with a total response rate of 62.75%. The total response rate regarding the cardiac function in the observation group was higher than that in the control group （χ²=4.923， P<0.05）. The observation group outperformed the control group in lowering the NT-proBNP level， elevating LVEF， decreasing the E/e' ratio （P<0.05）， reducing LVEDD and sST2 levels， and recovering TCM syndrome score， 6MWT score， MLHFQ score， and KCCQ score （P<0.05）. None of the safety indexes in the two groups showed abnormal values before and after treatment， and no serious adverse reaction was observed. ConclusionQifu Yixin prescription can improve the heart function， exercise tolerance， and quality of life and alleviate the TCM syndrome of the chronic heart failure patients with the syndrome of heart Qi deficiency by inhibiting myocardial fibrosis.

In general, the application conditions of linear regression models could be met after the natural logarithmic transformation of data. From the practical perspective, this paper introduced the linear regression models with natural logarithmic transformation of independent variable, dependent variable, and both independent and dependent variables in detail. The paper illustrated why the equation and coefficients could not be directly explained after the natural logarithmic transformation of data. The percentage changes of X and/or Y were applied to elaborate the principle and method for the explanation of the equation and coefficients. Three examples were used to fit simple linear models with natural logarithmic transformation of independent, dependent, and both independent and dependent variables and the results of theses models were explained in detail.
