Analyzing the results of finger systolic blood pressure tests in 28 healthy young adults / 中国职业医学

Objective To investigate the level of finger systolic blood pressure (FSBP) in healthy young adults. Methods A total of 28 healthy young adults were selected as the study subjects by convenient sampling method. The FSBP of the study subjects was detected at 30 and 10 ℃, and the FSBP index (Fi) was calculated. Results The FSBP of the study subjects at 30 and 10 ℃ were (102.0±16.5) and (104.4±15.2) mmHg, respectively. The FSBP in male group at 30 and 10 ℃ was (99.6±18.6) and (107.2±17.0) mmHg, respectively. The FSBP in female group at 30 and 10 ℃ was (104.4±13.9) and (101.5±2.8) mmHg, respectively. The results of factorial analysis showed that the interaction between gender and temperature on FSBP was statistically significant (P<0.05). FSBP in male group was higher at 10 than 30 ℃ (P<0.05) and higher than female group at 10 ℃ (P<0.05). There was no statistical significance for the main effect of gender, temperature, finger, or the interaction effect of gender and finger, temperature and finger for FSBP (all P>0.05). The average Fi of the study subjects was (98.0±16.6)%, with males and females having the average Fi of (100.7±20.7) % and (95.2±10.6) % respectively. The results of factorial analysis of variance showed that there was no significant difference on Fi in the main effect gender and fingers or the interaction effect between them(all P>0.05). Conclusion The FSBP test could be used as a detection method for assessing peripheral microcirculation function in Chinese population. However, further research is needed to establish reference ranges and influencing factors.

Research progress on the effect of sleep on obesity among adults / 预防医学

Abstract@#Obesity is a major global public health problem. Long-term sleep deprivation has been identified as a major risk factor of obesity among adults, and oversleeping is found to correlate with the increased risk of obesity. Based on systematic reviews, meta-analysis and prospective cohort studies of the association between sleep and obesity among adults published during the period between 2017 and April, 2022, this review summarizes the direct impact of sleep on obesity among adults, the improvements of adult obesity by sleep and the immune, endocrine, energy metabolism, dietary habit and psychological mechanisms of obesity affected by sleep, so as to provide insights into the development of interventions against adult obesity.

Relationship between obesity and insomnia among adults / 预防医学

Objective@#To investigate the association between obesity and insomnia among adults, so as to provide insights into obesity control and sleep health improvements among adult populations. @*Methods@#Sixteen communities were randomly sampled from Longgang District, Shenzhen City using a multistage cluster sampling method, and permanent residents at ages of 18 years and older living in these communities were recruited as study subjects. Subjects' gender, age, educational level and marital status were collected using a self-designed questionnaire, and the body mass index ( BMI) was calculated. The sleep quality was evaluated using the Insomnia Severity Index ( ISI ), and the correlation between obesity and insomnia was evaluated using a multivariable logistic regression model.@*Results@#A total of 10 434 questionnaires were allocated, and 9 425 valid questionnaires were recovered, with an effective recovery rate of 90.33%. The respondents included 3 448 men ( 36.58% ) and 5 977 women ( 63.42% ), and 6 940 respondents ( 73.63% ) were at ages of 18 to 44 years. There were 778 respondents with underweight ( 8.25% ), 5 522 with normal weight ( 58.59% ), 2 209 with overweight ( 23.44% ) and 916 with obesity ( 9.72% ). Among all respondents, 1 149 respondents were detected with insomnia, with a detection rate of 12.19%, including 839 subjects with mild insomnia ( 8.90% ), 247 subjects moderate insomnia ( 2.62% ) and 63 subjects with severe insomnia ( 0.67% ). Multivariable logistic regression analysis showed a statistically significant correlation between obesity and insomnia ( OR=2.179, 95%CI: 1.824-2.603 ).@*Conclusions@#There is a significant correlation between obesity and insomnia. Body weight management and sleep health education shall be intensified among adults.

The Treatment and Progress in Consolidation Therapy of APL / 现代生物医学进展

Acute promyelocytic leukemia (APL) was considered to be the most rapidly fatal leukemia,because of serve clinical manifestation,high rate of early death and the low cure rate.APL has achieved great success due to the application of ATRA and ATO.Although the complete remission rate is about 90％,the relapse rate has been reported to be as high as 15％-30％.So reducing the recurrence and improving long-time survival have become the focus of the study.Choosing the reasonable treatment after remission is very important.The post remission therapy usually include consolidation therapy and maintenance therapy,but the optimal strategy has been controversy.Therefore,this artical will review the literature of APL in consolidation therapy.

DNA methylation and affective disorder / 中华行为医学与脑科学杂志

Objective Recent years,epigenetics research mainly focused on DNA methylation.A growing body of research indicated that DNA methylation may play vital role in etiology of affective disorder.With brief introduction of DNA methylation molecular mechanisms and relevance of DNA methylation to affective disorder,this review focuses on some supporting evidence which are recently emerged in major depressive disorder (MDD) and bipolar disorder related gene DNA methylation.Methods We retrievaled related articles from databases,such as PUBMED,Foreign medical information resources retrieval platform,CNKI,Wanfang database,ect,from 2013-06 to 2015-01.Index strategy TI:[depression OR bipolar disorder OR affective disorder] AND All field:DNA methylation.Reading and narrowing the scope of the articles,the experimental design was understanded,such as DNA from either blood cell or brain parenchyma of sample,methods of methylation detection,gene detected and methylation position,etc.The articles included 168 in English and 32 in Chinese.The whole and retained the articles were red about MDD and bipolar disorder related gene DNA methylation in recent five years.Results Eventually,the article includes 29 articles and two of in Chinese.Most of them are receptor gene epigenetics research associated with disease.Conclusion MDD and bipolar disorder are associated with the higher of DNA methylation levels in multiple gene promoter region,such as GR,BDNF,5-HTR,SLC6A4 and the lower of COMT.This article only from the perspective of affective disorder reviewed the relationship between DNA methylation and diseases.None of other diseases epigenetics research,there is to be perfected in future.

The research progress of depression with suicide and event related potential / 中华行为医学与脑科学杂志

Objective ERP research has always been the hot spot of the n~ve electrophysiology research.A gTowing body of research suggests that ERP can effectively reflect the cognitive function in patients with depression,evaluate the risk of suicide.This paper reviews the ERP related components with depression and related research.On the basis of the application of ERP in the depression research discusses limitations and prospects on the later development.Methods The articles were retrievaled from databases,such as P UBMED,Foreign medical information resources retrieval platform,CNKI,Wanfang database,ect,from 2013-06 to 2015-01.Index strategy TI:TI:[depression OR affective disorder] AND [suicide OR suicidal] All field:event related potential.Reading and narrowing the scope of the articles,we should understand the experimental design,such as Sample company have suicidal ideation and (or) behavior of patients with depression.Potential induced way,ERP related component detection method,etc.The articles included 43 in English and 15 in Chinese.Read the full text and retain nearly five years about depression and related literature.Results Eventually,the article includes 34 articles and 3 of in Chinese.Conclusion Associated with suicidal ideation and (or) behavior of the existing cognitive dysfunction in patients with depression,ERP related components such as:abnormal P300 and CNV,MMN.N400 have not found abnormal.This article only from the Angle of depression and related research are reviewed in this paper the characteristics of ERP,ERP of other mental illnesses among related research,and to be perfect in the future.
