Objective To investigate the influence of family support on the psychology and life quality of patients with diabetic retinopathy. Methods To survey the family support status, psychological status and quality of life by the questionnaire among 86 cases of diabetic retinopathy (DR) patients and to do the correlation analysis. Results Most of the dimension scores and total score of CLVQOL of the group of low score of family support (33 cases) were significantly lower than the group of high score of family support (53 cases). The score of somatization, compulsion, interpersonal sensitivity, depression, anxiety, paranoia, psychosis and the SCL-90 total score of family support group with low scores was significantly higher than the family support group with high scores. Conclusions The family support can help maintain and improve the quality of life and the status of mental health of patients. Health care workers should pay more attentions to the guidance and education of the DR family members of patients to enhance the awareness of timely improved family support, to ensure the provision of high quality family support and promote the quality of life of patients.

Objective To investigate the role and possible mechanism of P120 catenin involving in the hemodynamic changes by inducing vascular endothelial cells injury through an in vitro experiment. Methods The hemodynamic environment under the different hemodynamic conditions at the vascular bifurcations was simulated through a T-shaped flow chamber system designed by ourselves. The human umbilical vein endothelial cells (HUVEC)cultured in vitro were stimulated and used the HUVEC cells of the small interfering RNA (SiRNA)after P120ctn gene fragments being knocked out. After loading flow rate of 250 and 500 ml/ min respectively and acting on for 12 h,the HUVEC morphology,growth pattern,and expression of P120ctn and other proteins were observed. Results (1)Normal HUVEC:500 ml/ min was loaded for 12 h,the cells were fused excessively at the impinging point,the cell gaps became narrowed,the cell density decreased and the morphology was elongated in the high wall shear stress (WSS)and wall
shear stress gradient (WSSG)regions. A part of cells migrated downstreamly,and their arrangement direction was consistent with the direction of impinging flow. Compared with the unloaded impinging flow field,after the 2 kinds of impinging flows being loaded for 12 h,the expression levels of P120ctn,vascular endothelial calcium (VEC),Kaiso,α-catenin,and other proteins were decreased. The expression level of matrix metalloproteinase 2 (MMP-2)was increased. There were significant differences (all P < 0. 05). (2)HUVEC after P120ctn being knocked out:Under the impact of the impinging flow,the cell growth time was reduced to 60 min. 250 ml/ min being loaded for 60 min,the impinging point and its surrounding cells still maintained the polygon,but some cells in the high WSS and high WSSG regions began to move downstreamly and aggregated,the cell arrangement mode partly arranged along with the direction of the flow;500 ml / min being loaded for 60 min,the cell density in the high WSS and high WSSG regions were decreased significantly and the morphology was elongated. A large number of cells migrated downstreamly and aggregated. The arrangement mode was parallel and consistent with the direction of the impinging flow. Compared with the unloaded impinging flow field,after the 2 kinds of velocities being loaded for 60 min,the expression levels of VEC,Kaiso,α-catenin proteins were decreased. The expression level of MMP-2 was increased,There were significant differences (all P < 0. 05) Conclusions The hemodynamic change may induce the changes in vascular endothelial cell morphology,growth pattern,and expression of P120ctn and other related proteins, leading to the decrease of vascular endothelial cell adhesion connection stability and the expression changes of related proinflammatory factors. The knockout of P120ctn may result in a further decrease of the vascular endothelial cell adhesion connection stability.

Objective:
To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD.
Methods:
Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model.
Results:
A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966).
Conclusion
The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.
