Objective To explore investigate the current situation of benefit finding and depression among breast cancer patients and to analyze the influencing factors of benefit finding of them so as to provide a basis for clinical practice.Methods A total of 216 breast cancer patients were selected as subjects by convenience sampling from four ClassⅢ hospitals in Shanghai. The general information, benefit finding and depression were investigated with the general information questionnaire, the Chinese version of Benefit Finding Scale (BFS) and Self-rating Depression Scale (SDS). Pearson correlation was used to analyze the correlation between them, and the multiple linear regression was used to analyze the influencing factors of benefit finding among breast cancer patients.Results The score of benefit finding and depression of breast cancer patients was (53.41±16.40) and (43.10±6.77) respectively with a negative correlation between them (r=-0.55,P< 0.01). Single factor analysis showed that there were statistical differences in benefit finding among breast cancer patients with different education levels, domiciles, marital status, mammary contour after surgery and depression (P<0.05). Multiple linear regression revealed that the influencing factors of benefit finding of breast cancer patients included education levels, marital status, mammary contour after surgery and depression (P< 0.05).Conclusions The benefit finding of breast cancer patients can influence depression of patients. Medical staff should actively guide patients to increase benefit finding of patients, reduce patients' depression and improve patients' life quality by appropriate methods.

Objective:To use Meta analysis to understand the prevalence of the heritability of body mass index (BMI) in twins.Methods:All studies on the heritability of the twins' BMI published before December 31, 2020 were retrieved through the China National Knowledge Network, Wanfang, VIP, PubMed and Web of Science databases. The literature quality was evaluated by using Joanna Briggs Institute Critical Appraisal tools. Stata 16.0 was used to perform subgroup analysis on the outcome indicators (heritability, 95% CI) to explore the source of heterogeneity. The local weighted regression method was used to fit the trend of heritability with age. The publication bias test and the sensitivity analysis of included literatures were also performed by using Stata 16.0. Results:A total of 10 articles meeting the inclusion and exclusion criteria were included with 79 twins' independent estimates of heritability for BMI. Meta-analysis showed that the combined value of BMI heritability was 0.69 (95% CI: 0.65-0.71), the combined value of BMI (0.68, 95% CI: 0.65-0.70) in males was lower than that (0.70, 95% CI: 0.68-0.72) in females. The heritability of BMI (0.72, 95% CI: 0.68-0.76) in childhood and adolescence was higher than that (0.68, 95% CI: 0.66-0.70) in adulthood. The gender specific difference in BMI heritability in twins ≤18 years old was even greater, which was lower in males (0.68, 95% CI: 0.61-0.76) than in females (0.75, 95% CI: 0.69-0.81). The heritability increased with age in childhood, reached peak at about 18 years old, and then slowly decreased with age. Conclusions:The heritability of BMI varied with population characteristics, especially age and gender. In view of the high estimated value of BMI heritability in female children and adolescents, more attention should be paid to the start time of health intervention.

Objective:To investigate the chemical constituents in the rattan of Rubia argyi L.. Methods:The air-dried rattan of Rubia argyi L. was powdered and extracted three times by 75% ethanol with refluxing. After removing the solvent under the reduced pressure,the crude extract was dissolved in water,and then filtrated and extracted by petroleum ether and ethyl acetate to obtain crude extract after removing petroleum ether and ethyl acetate. The compounds were isolated and purified by silica gel column chromatogra-phy,reversed-phase silica gel column chromatography and Sephadex LH-20 gel column chromatography,and then identified based on physicochemical properties and spectral analysis(1 H-NMR and 13C-NMR). Results:Totally 13 compounds were isolated from the rat-tan of Rubia argyi L.,and characterized as secoisolariciresinol(1),xanthopurpurin(2),daucosterol(3),dehydroabietic acid(4), 2-hydroxy-1-methoxy-anthraquinone(5),β-sitosterol(6),lirioresinol A(7),2-hydroxy-7-methyl-9,10-anthraquinone(8),strych-novoline (9), ciwujiatone (10), 3,4-divanillyltetrahydrofuran (11), 2-(4-hydroxypheny) -6-(3-methoxy-4-hydroxyphenyl)-3,7-dioxabicyclo[3,3,0]octane (12), and (6S,9R)-vomifoliol (13).Conclusion: The compounds 1-13 are isolated from the rattan of Rubia argyi L. for the first time and the compounds 1,2,4,5 and 7-13 are first isolated from Rubia L..

Objective:To quantitatively analyze the effects of population aging and other risk factors on the burden of atherosclerosis cardiovascular disease (ASCVD) in China from 1990 to 2019.Methods:Disability adjusted life years (DALY) and age-standardized rates obtained from the Global Burden of Disease Study 2019 (GBD2019) were used to describe the temporal trend of a burden on ASCVD. And a decomposition method established by Gupta was applied to quantify the burden related to population growth, aging, age-specific prevalence, and the severity of the disease.Results:In 2019, 61.00% of the burden of cardiovascular disease in China was caused by ASCVD. The DALY of ischemic heart disease increased by 133.66% compared with that in 1990, with 29.57% of the increase attributed to population growth, 108.74% due to population aging, and 8.87% due to the rise of age-specific prevalence and -13.53% benefited from changes in disease severity. The DALY of ischemic stroke increased by 138.64% compared with 1990, and the proportions attributable to the above four parts were 30.95%, 123.38%, 55.80%, and -71.49%, respectively. Hypertension remained the leading risk factor for ASCVD in 2019, followed by high LDL cholesterol. The age-standardized DALY rate attributable to drinking had the most significant increase (486.01%) from 1990, with an average annual growth of 10.93%.Conclusions:Aging population seems responsible for the main reason for the considerable increase in the burden of ASCVD in China. Still, the adverse trends of other avoidable risk factors, especially metabolic risk factors, can not be ignored.
