Chronic fatigue syndrome (CFS) is a common problem in military maritime navigation, which greatly affects the safety of military missions. The use of animal models to carry out research on the mechanism of CFS and treatment measures is a common method. This paper systematically introduced the construction methods of CFS models such as single-factor and multi-factor models, summarized common evaluation indicators of CFS, including behavioral and biochemical indicators, and summed up key characteristics of CFS animal models in military oceanic navigation combined with common causes of CFS in military contexts, such as prolonged continuous work, high-intensity physical activity, sleep deprivation, psychological stress, and extreme environmental conditions. The key characteristics of the animal models included, but not limited to, chronic fatigue, sleep disorders, impaired cognitive function, psychological stress responses, and abnormal biochemical indicators. Furthermore, this article identified future research directions for CFS animal models in military oceanic navigation to enhance the application value of the models and provide robust support for the health protection and disease prevention of military personnel.

Objective: To explore the effectiveness eye caring theme based intervention model in the improvement of students’ vision, and to provide a systematic method for pupils’ visual intervention. Methods: A total of 965 students in the same grade of the three schools were divided into intervention group(482) and control group(483) at a 1∶1 ratio match. The intervention group received a one year intervention through the design of the series of eye caring theme activities, and the control group did not receive any intervention. Results: The mean values of visual related knowledge literacy improvement in the intervention group and the control group were 7.08 and 2.18, respectively, with a significant difference( t =92.18, P <0.05); The mean values of improvement of vision related belief literacy in the intervention group and the control group were 7.88 and 4.57, respectively, and the difference was statistically significant( t =45.57, P <0.05); The mean values of visual related behavior literacy improvement in the intervention group and the control group were 17.41 and 2.21. The differences were statistically significant( t =117.37, P <0.05); The mean values of total vision improvement in the intervention group and the control group were 10.80 and 2.99, respectively, and the differences were statistically significant( t =87.74, P <0.05); The mean values of the parents’ improvement in children’s vision health care in the intervention group and the control group were 13.33 and 0.80, respectively, and the difference was statistically significant( t =128.76, P <0.05); The mean values of visual acuity reduction in the intervention group and the control group were 0.07 and 0.71, respectively, and the differences were statistically significant( t =128.00, P <0.05). Conclusion Theme based intervention can improve students’ visual literacy, especially visual behavior literacy, and can effectively slow down the deterioration of students’ vision.

Objective: To understand effects of timing and duration of separation experiences from parents on emotion regulation of left-behind preschoolers,and to provide the reference for phychological instruction and intervention among the special groups of children. Methods: Children’s emotion regulation strategy and the relevant information among 1 373 left-behind preschool children from Funan county in Fuyang.Qianshan county in Anqing,Changfeng county and Fexi county inFeixi were investigated. Results: Children with left-behind experiences younger than 18 months old tend to use less cognitive restructuring (P=0.03) and alternative action strategies (P=0.00) than non-left behind children. Children separated from father less than 47 months (median) and 36 months (median) from mother tend to use less cognitive restructuring (P=0.00) and alternative action strategies (P=0.00) than non-left behind children. Conclusion Separation experiences from parents younger than 18 months old exert severe damage on children’s emotional regulation. With the duration of separation increases, children show resilience of emotion regulation, which might be a protective factor for negative emotion due to parent-child separation.

Objective : To construct a visual literacy evaluation system for pupils by Delphi expert consultation method（Delphi method）. Methods : The visual literacy evaluation indices for pupils were preliminarily constructed through literature review. Twenty experts in relevant fields were invited and the visual literacy evaluation system for pupils was established by two rounds of expert consultation based on Delphi method. Results : The average age of 20 experts was（48.35±5.79）years old,of which 19 experts had senior titles,and 17 experts had master's degree or above. The enthusiasm of the experts in two rounds of consulting was both 100.00%. The average authoritative coefficient（W）of the experts was 0.88. For the first consulting round,the W of importance scores from experts was 0.91（P<0.01）;the W of operability scores from experts was 0.89（P<0.01）,which indicated satisfactory consistency. For the second consulting round,the W of importance scores from experts was 0.79（P<0.01）;the W of operability scores from experts was 0.77（P<0.01）,which also indicated satisfactory consistency. The finalized visual literacy evaluation system for pupils after two rounds of expert consultation included three primary indices（eye care knowledge literacy,eye care attitude literacy and eye care behavior literacy）,six secondary indices（basic knowledge,eye care behavior,eye care attitude,eye care willingness,bad eye care behavior and eye protection）and 40 tertiary indices（≥5.0 of eyesight among normal people,always wearing glasses due to poor eyesight and so on）. Conclusion The experts who participated in the construction of visual literacy evaluation system for pupils had strong professional representativeness,high enthusiasm,high authority and good coordination,and the evaluation system can be used for evaluating pupils visual literacy.

Objective To know the anxiety status of preschool children in rural areas and to explore its influential factors. Methods Subjects of 1363 rural preschool children aged 3-6 years were selected from Anhui Province( Changfeng and Feixi county of Hefei city; Qianshan county of Anqing city; Funan county of Fuyang city) . The primary caregivers of preschool children were investigated by Chinese version of Spence Preschool Anxiety Scale (SPAS),Devereux Early Childhood Assessment for Preschoolers (DECA-P2) ,Neglect Norms for Children Aged 3 to 6 Years in Rural Areas of China,Adaptation Partnership Growth Affection Resolve (APGAR),Self-rating anxiety scale (SAS) and Self-rating depression (SDS). Result-s Among the 1363 preschool children,the positive rate of anxiety was 14. 7％. Physical injury fears score was highest (1. 24±0. 84),followed by social phobia anxiety (0. 86±0. 75) and separation anxiety (0. 85± 0. 74) . Except for obsessive compulsive disorder,the other four types of anxiety and total anxiety scores were negatively correlated with the total protective factors of mental resilience (r=-0. 054- -0. 070,P<0. 05). Besides,all anxiety scores were positively correlated with behavioral problems(r=0. 121-0. 237,P<0. 05)and neglect degree (r=0. 157-0. 269,P<0. 05). The results of multiple linear regression analysis of different anxiety types showed that gender,family type,family income status,parental rearing pattern was consistent or inconsistent,children' s neglect degree,behavior problem and anxiety/depression status of primary caregivers were the main factors affecting the anxiety level of preschool children in rural areas. Conclusions In order to reduce or avoid anxiety of preschool children,it is necessary to establish a good family environment,im-prove parents' upbringing level,and take effective education intervention.

OBJECTIVE: To investigate the expressions of LL-37 and IL-8 in chronic sinusitis with nasal polyps. METHOD: Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemical staining were used to detect the expressions of LL-37 and IL-8 in nasal polyp tissues of 31 patients with chronic sinusitis and inferior turbinate tissues of 11 patients with chronic rhinitis. RESULT: LL-37 and IL-8 mRNA were all positively expressed in all nasal polyps and inferior turbinate tissues. There were significant increases of LL-37 and IL-8 mRNA expressions in nasal polyps compared with the inferior turbinate tissues (P < 0.01). There were also significant increases of positive expression rates of LL-37 and IL-8 protein in nasal polyps, compared with the inferior turbinate tissues (P < 0.01). There was a positive relationship between the mRNA and protein expressions of LL37 and IL-8 (P < 0.01). CONCLUSION The expressions of LL-37 and IL-8 in nasal polyps suggest that they may play a role in the pathogenesis of chronic sinusitis. Besides its innate immune, LL-37 could enhance human body's anti-infected function by increasing acquired immune.
