ABSTRACT
Objective@#To assess the effectiveness of online and offline myopia prevention and control health education interventions using wearable behavior monitoring tools for non myopic elementary school students,so as to provide evidence based medical support for public health practices.@*Methods@#From May to June in 2021, two schools were selected within the same county in Jiangsu Province. School 1 conducted online and offline parental health education ( n =111), while school 2 exclusively conducted offline health education activities, representing the traditional intervention group ( n =122). Students from both schools underwent monitoring through wearable behavior tracking tools, with feedback reports provided (eye distance, eye duration, ambient light, and outdoor exposure time). Both schools relied on activities to carry out health education interventions, and organized the distribution of promotional materials and display boards. The intervention group also established WeChat groups to conduct online "Healthy Parents Action" (answering and providing feedback on health knowledge related to myopia prevention and control, myopia prevention and control, science popularization, etc. raised by parents). Evaluation criteria included myopia rates, post dilation refractive error, and axial length, with a tracking period of two years (from 2021 to 2023). Additionally, the study collected refractive parameters from non myopic students who did not participate in wearable tool monitoring in the 12 classes across the two schools.@*Results@#The baseline results indicated that there were no significant differences between the two groups in terms of refractive parameters and wearable tool monitoring results (including screen time, viewing distance, outdoor exposure time, and homework light exposure)( t/Z/χ 2=1.94,1.17,0.58,0.40,0.80,0.69,0.32, P >0.05). After a two-year follow up, in the first and second year, the myopia rate of the online Healthy Parents Action group (11.4%, 29.7%) were lower than that of the traditional group (26.2%, 50.9%), and the degree of refractive change in the intervention group [0.63(0.38,1.19)D] was lower than that of the traditional group [0.91(0.40,1.50)D], and all the differences were statistically significant( χ 2/ Z =4.93，10.37，2.29， P <0.05). However, there were no significant differences ( P >0.05) in axial length changes between the two groups over the twoyear intervention period. Nevertheless, in the second year, the axial length change in the traditional group [0.35(0.20,0.65)mm] was lower than that in the natural observation group [0.55(0.30,0.75)mm], and this difference was statistically significant ( Z =1.92, P <0.05).@*Conclusions@#Online and offline myopia prevention and control health education can effectively reduce myopia rates. The intervention mode combining wearable behavior monitoring tools with online health education may have better effects, but further large sample and multi center studies are needed to provide additional evidence and confirmation.
ABSTRACT
Objective To compare the degree of coronary lesions in different types of heart failure with ischemic heart disease. Methods This retrospective analysis include 282 cases diagnosed as heart failure with ischemic heart disease in Zhengzhou People′s Hospital from January 2015 to May 2016. Based on LVEF and the level of BNP and NT-proBNP examination results ,282 cases were divided into HFmrEF(89 cases),HFrEF(109 cases) and HFpEF (84 cases). The clinical basic data ,cardiac color Doppler ultrasound and the difference of coronary artery lesions were compared. Results (1) HFpEF,HFmrEF and HFrEF groups gensini score were 30.45 ± 33.18,62.12 ± 41.25,86.72 ± 38.80. The differences are significant(P < 0.05). Pairwise comparison showed significant difference.(2)HFpEF,HFmrEF and HFrEF groups SYNTAX score were 11.77 ± 8.39,19.08 ± 8.39,26.41 ± 10.31. Compared with HFpEF group,the SYNTAX score of other groups are higher(P < 0.05). (3)The duration of disease ,LVEDD ,LVESD ,LVMI ,the number of vascular lesions was significantly higher in HFrEF group than those in other groups. (4) Multivariate correlation analysis suggested that SYNTAX scores were related to cardiac function classification,BNP,NT-proBNP and LVEF. Gensini integral is related to cardiac function classification ,BNP and NT-proBNP. Conclusions With the severity and complexity of coronary artery disease,the degree of heart failure is more serious. The complexity and severity of coronary artery disease is an important factor in heart failure in patients with ischemic heart disease.

ABSTRACT
@#Objective To establish a coupled model combining the rat brain nuclei microelectrode recordings and the behavioristics for rehabilitation experiment. Methods The modified indwelling tube connection fixed device was put inside the rats' back, and the microprobes were implanted into related neural nucleus. A signal connection was made between self-administration system and electrophysiological data acquisition system. The rat was addicted after training by self-administration system. The related cerebral nucleus electrophysiological sig-nals were recorded in different states of addiction. Results and Conclusion The modified indwelling tube connection fixed device has a bet-ter quality for reducing the phenomenon of leak. The signal was well in the combination of two different systems. The signals for the rat's ac-tion and neural electrical were recorded in the same time.
