BACKGROUND: Cognitive impairments are often accompanied in patients with silent cerebral infarction (SCI) and depression, and there is still no reliable objective assessing method for the evaluation.OBJECTIVE: The purpose of this study was to probe into the value of auditory P300 in detecting the cognitive impairment in SCI patients with depression.DESIGN: A golden standard control study.SETTING: Department of Neurology, Xi 'an Central Hospital; Department of Neurology, the Second Hospital of Xi' an Jiao Tong University.PARTICIPANTS: Thirty-eight SCI patients were selected from the Outpatient Department of Neurology, the Second Hospital of Xi' an Jiao Tong University between January 2002 to May 2003, including 10 got dizziness,11 got poor concentration, 8 got headache, 5 got numbness of extremities and 4 got syncope. Among them, 26 were detected by CT and 12 by MRI.The patients'aged 45 to 63 years with mean age of (57.3±5.1) years, including 20 males and 18 females.METHODS: The existence of depressive symptoms was measured with the 17-item Hamilton depression scale (HAMD). In this scale, the total score ranged from 0 to 52, with higher score indicating more severe depressive symptoms, and the patient was considered as having depression if the HAMD score was ≥ 9. HAMD tests were administered by two psychiatrists,who were experienced in psychiatric disorders in stroke and other somatic diseases, and the two psychiatrists had a better coincidence (Kappa=0.86 -0.91). The auditory event related potential was detected with MYTO serial cerebra induced potential meter, while lying in a bed placed in a sound-attenuated room. Auditory stimuli were delivered binaurally through headphones. The subject was required to distinguish between the tones by noting the occurrence of the target and not to respond to the standard. All patients underwent a routine experimental test at first, and then a normal test was performed to obtain a better coincidence. Mini-mental state examination (MMSE) was conducted for the 38 patients by specialized training neurologist to assess the cognitive impairment, in which the total score ranged from 0 to 30, with lower score indicating greater impairment. The criteria of intellectual deterioration was defined on the basis of educational level:MMSE score of 17 for illiterate, 20 for primary school and 24 for middle school and above.MAIN OUTCOME MEASURES: The score of MMSE, latent period of P300 wave and amplitude of P300 wave were mainly observed.RESULTS: All the 38 cases were involved in the final statistical analyhave depressive symptoms (47%, depression group) and 20 had no depresindexes and score of MMSE between the SCI patients with and without depression: As compared with the SCI patients without depression, the P300 latent period was obviously prolonged, the P300 amplitude and MMSE score were markedly decreased in the SCI patients with depression [(383.3±31.1), (347.2±37.3) ms; (5.6±0.7), (9.9±1.6) μV; (15.2±1.1),and P300 indexes: In the SCI patients with depression, the P300 latent period had significant negative correlation with the MMSE score (r=-0.549, P ＜ 0.05), the P300 amplitude had significant positive correlation with the MMSE score (r =0.525, P ＜ 0.05). However, there was no correlation between the latent period and amplitude of P300 and the MMSE score in the SCI patients without depression (r=-0.349 to 0.065, P ＞ 0.05).CONCLUSION: Depression and cognitive impairments may have the same pathophysiological basis in SCI patients. P300 can be used as a referential and objective method to analyze the cognitive function in SCI patients with depression.

With the development of business of manned spaceflight, the body damage of astronauts on the space en-vironment has received growing concern. Weight loss is the most important cause of various diseases, and the weightlessness muscle atrophy is one of urgent problems to be solved in aerospace medicine. Although there is no concept of weightlessness or weightlessness muscle atrophy in the theory of traditional Chinese medicine (TCM), TCM can grasp the pathogenesis of complex diseases, and provide important theoretical references for the prevention and management of weightlessness diseases, especially weightlessness muscle atrophy. In this paper, TCM Cognition of weightlessness and the pathogenesis of weightlessness muscle atrophy was studied by the sight of TCM theory of qi hoisting. The discussion was made from aspects of circulation of qi and blood, zang-fu function. This work is wished to be beneficial to apply the TCM theory in aerospace medicine.

Objective: To understand the relationship between parental nutritional literacy and dietary behaviors of primary school students in Bao an District of Shenzhen, so as to provide a basis for promoting childhood healthy eating habits. Methods: In December 2022, a total of 2 293 students in grades 4-6 and their parents from seven schools in Baoan District, Shenzhen were surveyed with questionnaire by using stratified cluster random sampling method. Multiple linear regression model was used to explore the relationship between parental nutrition literacy and dietary behaviors among primary school students. Results: The mean score of parental total nutritional literacy was (75.04±8.08), and the mean scores of the three dimensions for basic knowledge and concepts, basic skills and lifestyle and dietary behaviors were (24.23±2.45) (34.99±5.61), and (15.82±2.56), respectively. The mean total nutrient literacy score of parents with normal body mass index (BMI) was (75.47±8.04), which was higher than that of parents with abnormal BMI (74.45±7.85) ( t=2.78, P <0.01); and the mean dietary behavior score of primary school students whose parents were sufficient nutritional literacy (32.45±3.02) was higher than those of parents with low nutritional literacy ( 30.98± 3.60) ( t=9.22, P <0.01). In multiple linear regression analyses, after adjusting for gender, grade, household registration, parental education, parental occupation, whether living with their parents, and parental BMI of primary school students and other factors, parental basic knowledge and concepts ( β=0.13, 95%CI =0.07-0.19), basic skills ( β=0.10, 95%CI =0.08-0.13), lifestyle and dietary behaviors ( β=0.28, 95%CI =0.23-0.34), and total nutritional literacy level ( β=0.09, 95%CI =0.07-0.11) were positively correlated with healthy dietary behaviours of primary school students ( P <0.05). Conclusions As parental nutritional literacy increases in Bao an District of Shenzhen, unhealthy dietary behavior among primary school students also relatively decreases. It s recommended that comprehensive parental nutritional literacy interventions should be enhanced to foster healthy dietary behaviors in children.

Objective: To explore the effect of orienteering exercises on the improvement of children s executive function, and to explore the relationship between executive function and orienteering intervention to provide theoretical support. Methods: Forty children from the fourth grade of Zhonghai the First Experimental Primary School in Changchun City were selected as the experimental subjects, 20 as the experimental group (10 males, 10 females) and 20 as the control group (10 males, 10 females). The functional changes of executive function subfunctions (inhibitory function, conversion function, refresh function) before and after orienteering exercises intervention were measured by More odd shifting, 1 back and Flanker. Results: After intervention, the inhibitory function, conversion function and refresh function were significantly decreased in the experimental group (10.29±15.99, 295.19±189.76, 642.85±220.78)ms compared with before intervention (25.62±10.18, 616.04±287.92, 1 051.25±275.00)ms (F=12.52, 20.76, 20.89, P<0.01), while there was no significant change in the control group (P>0.05). In this study, neither gender main effect nor interaction between sex × group, sex × time and sex × time × group were found (P>0.05). Conclusion Orienteering exercises can significantly improve children s executive function, which are not vaired by sex.

Objective:To investigate the biofilm-forming abilities of pathogens associated with contact lens related microbial keratitis and to compare the efficacies of different treatments in eliminating biofilms in contact lens cases (CLCs).Methods:Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans biolm formation in polypropylene CLCs was examined by using a static biofilm formation model, which was incubated at 37 ℃ for 24 hours.According to the CLC treatment methods, the experimental groups were divided into a control group, a room temperature air-drying group, a contact lens care solution soaking group, a heat-drying group and a soaking-heating group.A pathogen colony counting-based serial dilution micro-counting method was applied to evaluate the biofilm elimination efficacies and pathogen killing rates of treatments.Results:All four tested strains formed biofilms on the inner walls of the CLC, and the biomasses of S. aureus, P. aeruginosa, E.coli and C. albicans biofilm were (10.78±2.12), (9.19±0.57), (8.03±0.30), and (7.50±0.07)lg CFU/ml, respectively.The S. aureus biofilm biomass was significantly higher than those of the other strains (P<0.05). The biofilm biomasses of all the tested strains in the heat-drying and the soaking-heating groups were significantly lower than those in the control group (all at P<0.05); and the biofilm biomasses of S. aureus and E. coli in the soaking group were significantly lower than that in the control group (all at P<0.05). The heat-drying treatment resulted in a killing rate of (51.76±16.75)% for S. aureus, (68.63±4.43)% for P. aeruginosa, (83.51±13.97)% for E. coli, and (97.13±5.19)% for C. albicans, respectively (F=31.806, P<0.001). Significant differences were observed between the killing rates for each bacterium (all at P<0.05). The E. coli and C. albicans killing rates of the soak-heating treatment were (100.00±0.00) % and (97.79±7.67)%, respectively, and were significantly higher than (81.13±14.86)% of S. aureus and (74.22±11.91)% of P. aeruginosa (all at P<0.05).Conclusions:Heating alone or combined with the use of contact lens care solution treatment can improve the pathogen killing rates and effectively eliminate the bacterial and fungal contaminations in CLCs.

【Objective】 To investigate the feelings of blood donors during blood donation and its influencing factors, thus providing references for high quality blood donation service for blood banks. 【Methods】 A self-developed questionnaire concerning voluntary blood donation was randomly issued by the research group and recruited investigators among blood donors in 6 street blood donation sites of Nanjing Red Cross Blood Center at weekends during December 1~23, 2018. The basic information of blood donors, the difference of feelings during blood donation and the influencing factors were analyzed by descriptive analysis, chi-square test and binary Logistic regression analysis, respectively. 【Results】 A total of 405 questionnaires were issued, and all 405 copies were valid, with the response rate at 100% (405/405). Among the valid questionnaires, 46.67% (189/405) were first-time blood donors, 27.65% (112/405) had donated for 2~3 times, and 25.68% (104/405) donated more than 4 times. 53.59%(97/181), 23.7%(43/181) and 22.65%(41/181) of the above three groups of blood donors worried about the needles, and 55.48%(81/146), 22.60%(33/146) and 21.92%(32/146) worried about the blood outflow, 52.69% (88/167), 28.14% (47/167), and 19.16% (32/167 )worried about the pain during blood collection (P<0.05). The anxiety of unqualified blood test was similar to that of poor service (P>0.05). There were differences in blood donation experience among the three groups (P<0.05), and gender (P<0.05) was its influencing factor showed by binary Logistic regression analysis. 【Conclusion】 The majority of blood donors, who have donated at the street sites of Nanjing, are worried during blood donation collection. Therefore, the blood centers should provide high-quality services and humanized nursing interventions as well as strengthen the citizens′ awareness of blood donation.
